The current study was designed to compare the effects of oral administration of the streptococcal preparation, OK-432, as an adjuvant immunotherapy versus those of intradermal administration of OK-432 on the survival of patients after surgery for gastric cancer. The patients were stratified into two groups after surgery: a curative surgery stratum and a palliative surgery stratum. Then the patients in each stratum were randomly assigned into three groups: an oral placebo group, an oral OK-432 group, and an intradermal OK-432 group. All of the patients were given fluoropyrimidines orally in combination with OK-432 or placebo for 2 years after surgery. A total of 1011 patients were registered between 1982 and 1985, and 970 patients were eligible for statistical analysis. The survival rate of the oral OK-432 group was significantly higher than those of the other two groups after curative surgery. There were no significant difference in the survival rates between the three groups after palliative surgery, however. The effect of oral OK-432 was quite pronounced in patients after curative surgery for stage II to IV gastric cancer, especially in those patients with regional node involvement. Furthermore, it was found that the spleen is necessary for effective immunotherapy with oral OK-432, because the survival rate of the oral OK-432 group was significantly improved in patients whose spleens were preserved, when compared with splenectomized patients. These results demonstrate that oral adjuvant immunotherapy with OK-432 is beneficial after curative surgery for gastric cancer. PMID:1632701

To study the effect of piezosurgery in the extraction of mandibular impacted third molars. 228 mandibular impacted third molars with relative difficulty for extraction according to the scheme of degree of difficulty for extraction were included in the study, and were divided into two groups (114 teeth each group): Test group (treated by piezosurgery), control group (treated by traditional chisel osteotomy). The surgery time and pain, restriction of mouth opening and facial swelling after surgery, were evaluated in both groups. The average surgery time was (16 +/- 5.2) min in test group and (30 +/- 8.7) min in control group. The surgery time, pain, facial swelling rate, and restriction of mouth opening were lower than control group (P<0.05). Compared with traditional chisel osteotomy, the average surgery time with piezosurgery was significantly shorter and the complications are obviously reduced.

Physiological and psychosocial factors might contribute to differences in weight loss, eating behaviour and health-related quality of life (HRQoL) after bariatric surgery. The aim of this study was to investigate how perceived control over eating changes after bariatric surgery and whether it affects outcome in super-obese patients. In a retrospective analysis of a prospective study (n = 60), 49 patients were divided into two groups based on eating control 2 years after surgery, as assessed by the Three-Factor Eating Questionnaire-R21 (TFEQ-R21): 29 with good eating control (GC) and 20 patients with poor eating control (group PC). Eating behaviour and generic and condition-specific HRQoL was assessed by questionnaires. There were significant differences in all TFEQ-R21 domains 2 years after surgery in favour of group GC; uncontrolled eating p < 0.001, emotional eating p < 0.001 and for cognitive restraint p = 0.04. The improvement in HRQoL 2 years after surgery was significantly less in group PC compared to group GC in 7 of 8 SF-36 domains (p < 0.05). Mean (SD) percentage of excess body mass index lost was similar between groups, 71.2 (17.8) in group GC versus 65.4 (17.4) in group PC 2 years after surgery (p = 0.27). However, group GC had a significant weight loss between first and second year after surgery (p < 0.001) compared to group PC (p = 0.15). In super-obese patients, perceived poor control over eating 2 years after bariatric surgery was associated with lower HRQoL and more emotional and cognitive restraint eating, than good control overeating.

To describe the incidence and outcomes of reoperations for glaucoma in the Tube Versus Trabeculectomy (TVT) Study. Cohort study of patients in a multicenter randomized clinical trial. The TVT Study enrolled 212 patients with medically uncontrolled glaucoma who had previous cataract and/or glaucoma surgery. Randomization assigned 107 patients to surgery with a tube shunt (350 mm(2) Baerveldt glaucoma implant) and 105 patients to trabeculectomy with mitomycin C (0.4 mg/mL for 4 minutes). Data were analyzed from patients who failed their assigned treatment and had additional glaucoma surgery. Outcome measures included intraocular pressure (IOP), use of glaucoma medications, visual acuity, surgical complications, and failure (IOP >21 mm Hg or not reduced by 20%, IOP ≤5 mm Hg, additional glaucoma surgery, or loss of light perception vision). Additional glaucoma surgery was performed in 8 patients in the tube group and 18 patients in the trabeculectomy group in the TVT Study, and the 5-year cumulative reoperation rate was 9% in the tube group and 29% in the trabeculectomy group (P = .025). Follow-up (mean ± SD) after additional glaucoma surgery was 28.0 ± 16.0 months in the tube group and 30.5 ± 20.4 months in the trabeculectomy group (P = .76). At 2 years after a glaucoma reoperation, IOP (mean ± SD) was 15.0 ± 5.5 mm Hg in the tube group and 14.4 ± 6.6 mm Hg in the trabeculectomy group (P = .84). The number of glaucoma medications (mean ± SD) after 2 years of follow-up was 1.1 ± 1.3 in the tube group and 1.4 ± 1.4 in the trabeculectomy group (P = .71). The cumulative probability of failure at 1, 2, 3, and 4 years after additional glaucoma surgery was 0%, 43%, 43%, and 43%, respectively, in the tube group, and 0%, 9%, 20%, and 47% in the trabeculectomy group (P = .28). Reoperations to manage complications were required in 1 patient in the tube group and 5 patients in the trabeculectomy group (P = .63). The rate of reoperation for glaucoma was higher following trabeculectomy with mitomycin C than tube shunt surgery in the TVT Study. Similar surgical outcomes were observed after additional glaucoma surgery, irrespective of initial randomized treatment in the study. Copyright © 2014 Elsevier Inc. All rights reserved.

Studies evaluating the return to sports and work after shoulder arthroplasty are rare, and there are no studies evaluating return to work after total shoulder arthroplasty (TSA). Patients undergoing TSA will be able to return to their preoperative sports levels and occupations. Case series; Level of evidence, 4. A total of 154 patients with 170 TSAs for primary glenohumeral arthritis were included. Two subgroups were formed: patients who had participated in sports during the 5 years before surgery (group 1; n = 105 [68%]) and patients who had never participated in sports (group 2; n = 49 [32%]). The return-to-work rate in patients who had not retired after surgery were also analyzed, as were responses to a survey. The mean age at the time of surgery was 71 years (range, 33-88 years) in group 1 and 76 years (range, 54-88 years) in group 2. Mean follow-up time was 6.2 years (range, 2.5-12.6 years). Fifty-seven patients (54%) in group 1 participated in sports right up to the time of surgery. All 57 (100%) returned to sports after surgery. A further 3 patients (3%) from group 1 resumed sporting activity after surgery; swimming was the most popular sport. No patient in group 2 started sports activity after shoulder replacement surgery. Many of the patients, 14% of the entire group, had retired by final follow-up because of TSA. Fourteen percent of patients in group 1 and group 2 were pursuing their work at the time of most recent follow-up. Thirty patients of the entire cohort (19.5%) had to change their occupations because of surgery. Patients who participated in sports before TSA were successfully able to return to sports activities after surgery. Patients who did not participate in sports just before surgery were unlikely to start sports after surgery. Fourteen percent of the entire cohort was able to return to work after surgery. © 2014 The Author(s).

This study examined the influence of preoperative administration of amiodarone and metoprolol in preventing postoperative atrial fibrillation (AF) after coronary artery bypass grafting (CABG) surgery.The study comprised 251 patients who underwent CABG surgery at our hospital between January 2012 and May 2014. The patients were randomly divided into 2 groups: amiodarone therapy group (n = 122 patients) and metoprolol therapy group (n = 129 patients).In the amiodarone group, the patients received amiodarone tablet orally 1 week before coronary bypass surgery and during the postoperative period. In the metoprolol group, the patients received metoprolol tablet orally 1 week before surgery and during the postoperative period. The AF development rate was retrospectively evaluated between the first 3 days and 4 weeks after surgery.AF developed in 14 patients in the amiodarone group and 16 patients in the metoprolol group 4 weeks after the operation (P = 0.612).No significant difference was observed between the groups in terms of intensive care unit and hospital stay. Furthermore, hospital charges were similar in both groups (P = 0.741).The results of the logistic regression analysis showed age, left ventricular ejection fraction, left atrial diameter, and aortic cross-clamping time to be predictors for postoperative AF.This study demonstrates that amiodarone and metoprolol have similar effects in prevention of AF after cardiac surgery. However, larger-scale studies need to be conducted to substantiate these findings.

Objective: An evaluation is made of pain, swelling and peri-implant attached mucosal width after implant-based rehabilitation involving guided surgery and a modification of the technique with the raising of a semicircular miniflap, in single and partial replacements. Study design: A case-control study was carried out. The study group consisted of 12 patients with the placement of 19 implants using a guided surgery and miniflap technique. The control group consisted of 12 patients with the placement of 22 implants using the conventional technique. Each patient scored postoperative swelling and pain by means of a visual analog scale (VAS). Attached vestibular mucosa width was evaluated 12 weeks after implant placement. Results: Twelve operations were carried out in each group. Immediate aesthetics were established for all implants of the study group. One implant failed in each group. Maximum pain was recorded after 6 hours in both groups (mean VAS score 4 and 4.9 in the study and control group, respectively). Maximum swelling was recorded after 24 hours (mean VAS score 2.5) in the study group and on the second day (mean VAS score 3.4) in the control group. The mean attached vestibular mucosa width was 2.9 mm in the study group and 3.2 mm in the control group. Conclusion: In this preliminary study, guided implant surgery with a semicircular miniflap in single and partial replacements resulted in slightly less postoperative pain and swelling than with the conventional implant technique. The attached vestibular mucosa width was greater in the control group, though the differences were very small. Key words:Guided surgery, flapless surgery, miniflap, peri-implant mucosa.

The aim was to study the risk of non arteritic ischemic optic neuropathy after phacoemulsification cataract surgery. This study was conducted at King Hussein Medical Center during the period between January 2015 and July 2016. Patients attending ophthalmology clinic complaining of decreased vision due to lens opacity were evaluated. Patients were divided into two groups. First group included patients with no medical illness and second group included patients with diabetes mellitus, hypertension or hyperlipidemia. The two groups were further divided into two subgroups. First subgroup included patients who had phacoemulsification surgery and second subgroup did not have surgery. All patients were followed up for 6 months. They were assessed by neuro-ophthalmologist looking for ischemic optic neuropathy. A total number of 568 patients were enrolled. Group 1A included patients with no medical illness who underwent surgery and group 1B did not undergo surgery. The number of patients in these two subgroups was 119 and 103 respectively. Number of patients in group 2A (medical illness and surgery) was 188 and number of patients in group 2B (medical illness and no surgery) was 130. The incidence of ischemic optic neuropathy was 4.3 % in group 2A, 4.2 % in group 1A, 0.8% in group 2B, and 0% in group 1B. Phacoemulsification is a risk factor for non arteritic ischemic optic neuropathy independent of the presence of medical risk factors. Suggested mechanisms would be local anaesthesia, intraocular pressure fluctuation and local intraocular inflammation.

Infusions of carbohydrates before surgery have been shown to reduce postoperative insulin resistance. Presently, we investigated the effects of a carbohydrate drink, given shortly before surgery, on postoperative insulin sensitivity. Insulin sensitivity and glucose turnover ([6, 6,(2)H(2)]-D-glucose) were measured using hyper-insulinemic, normoglycemic clamps before and after elective surgery. Sixteen patients undergoing total hip replacement were randomly assigned to preoperative oral carbohydrate administration (CHO-H, n = 8) or the same amount of a placebo drink (placebo, n = 8) before surgery. Insulin sensitivity was measured before and immediately after surgery. Patients undergoing elective colorectal surgery were studied before surgery and 24 h postoperatively (CHO-C (n = 7), and fasted (n = 7), groups). The fasted group underwent surgery after an overnight fast. In both studies, the CHO groups received 800 ml of an isoosmolar carbohydrate rich beverage the evening before the operation (100g carbohydrates), as well as another 400 ml (50g carbohydrates) 2 h before the initiation of anesthesia. Immediately after surgery, insulin sensitivity was reduced 37% in the placebo group (P < 0.05 vs. preoperatively) while no significant change was found in the CHO-H group (-16%, p = NS). During clamps performed 24h postoperatively, insulin sensitivity and whole-body glucose disposal was reduced in both groups, but the reduction was greater compared to that in the CHO-C group (-49 +/- 6% vs. -26 +/- 8%, P> 0.05 fasted vs. CHO-C). Patients given a carbohydrate drink shortly before elective surgery displayed less reduced insulin sensitivity after surgery as compared to patients undergoing surgery after an overnight fast.

Purpose Ab interno trabeculectomy (AIT) with the Trabectome has been shown to reduce intraocular pressure (IOP) in eyes with pseudoexfoliation (PEX) glaucoma. Here, we examined the change of IOP fluctuations before and after only AIT or AIT with cataract surgery in PEX patients using the contact lens sensor Triggerfish®. Methods This was a prospective open-label study. Twenty-four consecutive patients with PEX glaucoma were included. Twelve patients underwent cataract surgery and AIT (triple-surgery group), and 12 patients underwent only AIT (single-surgery group). In each eye, IOP fluctuations over 24 h were measured with the contact lens sensor before and at 3 months after the surgery. We compared the change of IOP fluctuation before and after operation. We also evaluated the difference in IOP changes between the triple- and single-surgery groups. Results At 3 months after the surgeries, the mean IOP was significantly reduced from 23.5±6.5 mmHg to 14.6±2.8 mmHg in the single-surgery group and from 22.5±3.0 mmHg to 11.5±2.9 mmHg in the triple-surgery group. The mean IOP reduction rate was significantly higher in the triple-surgery group compared to the single-surgery group (p=0.0358). In both groups, the mean range of IOP fluctuations was significantly decreased during nocturnal periods. The mean range of 24 h IOP fluctuations was decreased in the triple-surgery group (p=0.00425), not in the single-surgery group (p=0.970). Conclusion Triple surgery could decrease IOP value and the IOP fluctuations to a greater extent than single surgery in PEX glaucoma patients. PMID:28979095

The aims of the study were to assess the degree of accuracy of model surgery performed manually using the Eastman technique and to compare it with model surgery performed with the aid of a robot arm. Twenty-one patients undergoing orthognathic surgery gave consent for this study. They were divided into 2 groups based on the model surgery technique used. Group A (52%) had model surgery performed manually, whereas group B (48%) had their model surgery performed using the robot arm. Patients' maxillary casts were measured before and after model surgery, and results were compared with those for the original treatment plan in horizontal (x-axis), vertical (y-axis), and transverse (z-axis) planes. Statistical analysis using Mann-Whitney U test for x- and y-axis and independent sample t test for z-axis have shown significant differences between both groups in x-axis (P =.024) and y-axis (P =.01) but not in z-axis (P =.776). Model surgery performed with the aid of a robot arm is significantly more accurate in anteroposterior and vertical planes than is manual model surgery. Robot arm has an important role to play in orthognathic surgery planning and in determining the biometrics of orthognathic surgical change at the model surgery stage.

Purpose. To compare the corneal endothelial cell loss after phacoemulsification, alone or combined with microinvasive glaucoma surgery (MIGS), in nonglaucomatous versus primary open angle glaucoma (POAG) eyes affected by age-related cataract. Methods. 62 eyes of 62 patients were divided into group 1 (n = 25, affected by age-related cataract) and group 2 (n = 37, affected by age-related cataract and POAG). All patients underwent cataract surgery. Group 2 was divided into subgroups A (n = 19, cataract surgery alone) and B (n = 18, cataract surgery and MIGS). Prior to and 6 months after surgery the patients' endothelium was studied. Main outcomes were CD (cell density), SD (standard deviation), CV (coefficient of variation), and 6A (hexagonality coefficient) variations after surgeries. Results. There were no significant differences among the groups concerning preoperative endothelial parameters. The differences in CD before and after surgery were significant in all groups: 9.1% in group 1, 17.24% in group 2A, and 11.71% in group 2B. All endothelial parameters did not significantly change after surgery. Conclusions. Phacoemulsification determined a loss of endothelial cells in all groups. After surgery the change in endothelial parameters after MIGS was comparable to the ones of patients who underwent cataract surgery alone. PMID:26664740

Recurrent postoperative CRPS I in patients with abnormal preoperative sympathetic function.

Ackerman, William E; Ahmad, Mahmood

2008-02-01

A complex regional pain syndrome of an extremity that has previously resolved can recur after repeat surgery at the same anatomic site. Complex regional pain syndrome is described as a disease of the autonomic nervous system. The purpose of this study was to evaluate preoperative and postoperative sympathetic function and the recurrence of complex regional pain syndrome type I (CRPS I) in patients after repeat carpal tunnel surgery. Thirty-four patients who developed CRPS I after initial carpal tunnel releases and required repeat open carpal tunnel surgeries were studied. Laser Doppler imaging (LDI) was used to assess preoperative sympathetic function 5-7 days prior to surgery and to assess postoperative sympathetic function 19-22 days after surgery or 20-22 days after resolution of the CRPS I. Sympathetic nervous system function was prospectively examined by testing reflex-evoked vasoconstrictor responses to sympathetic stimuli recorded with LDI of both hands. Patients were assigned to 1 of 2 groups based on LDI responses to sympathetic provocation. Group I (11 of 34) patients had abnormal preoperative LDI studies in the hands that had prior surgeries, whereas group II (23 of 34) patients had normal LDI studies. Each patient in this study had open repeat carpal tunnel surgery. In group I, 8 of 11 patients had recurrent CRPS I, whereas in group II, 3 of 23 patients had recurrent CRPS I. All of the recurrent CRPS I patients were successfully treated with sympathetic blockade, occupational therapy, and pharmacologic modalities. Repeat LDI after recurrent CRPS I resolution was abnormal in 8 of 8 group I patients and in 1 of 3 group II patients. CRPS I can recur after repeat hand surgery. Our study results may, however, identify those individuals who may readily benefit from perioperative therapies. Prognostic I.

ABSTRACT Background: Respiratory physiotherapy plays an important role preventing complications in bariatric surgery. Aim: To assess the effects of out-patient physiotherapy during post-operative period through respiratory pressures and functional capacity in individuals submitted to bariatric surgery. Method: A prospective longitudinal and controlled study was done in adults with body mass index (BMI) equal or greater than 40 kg/m², who have been submitted to bariatric surgery. They were divided into two groups: intervention-group, who performed out-patient physiotherapy twice a week, from thirty to sixty days after surgery; and the control-group, who only followed home instructions. Both groups were evaluated before surgery and sixty days after surgery through manovacuometry, six-minute walk test and the Borg Scale of perceived exertion. Results: Twenty participants were included the intervention-group and twenty-three in the control-group. Both groups had significant and similar weight loss after surgery. The manovacuometry presented no differences comparing pre- and post-surgery and in the comparison between the groups. The result of the six-minute walk test for the intervention-group increased by 10.1% in the post-operative period in relation to pre-. The Borg scale of perceived exertion in the intervention-group in pre-surgery decreased by 13.5% in the post-surgery compared to pre-surgery. In the control-group there was no difference comparing pre- and post-operative values, as in the comparison with the intervention-group. Conclusion: The low-intensity exercise program, carried out between the 30th and the 60th day after bariatric surgery provided better functional capacity; did not change respiratory muscle strength; and improved the perceived exertion rate.

Endometriosis affects 2-50% of women at reproductive age. Surgery is an option for treatment, but there is no convincing evidence that it promotes a significant improvement in fertility. Also, the removal of ovarian endometrioma might lead to a reduction in the follicular reserve and response to stimulation. Therefore, the aim of this study was to evaluate the effect of previous ovarian surgery for endometriosis on the ovarian response in assisted reproduction treatment cycles and its pregnancy outcome. A total of 61 women, with primary infertility and previously having undergone ovarian surgery for endometriosis, who had received 74 IVF/intracytoplasmic sperm injection (ICSI) cycles, were studied (study group). A further 74 patients with primary infertility who underwent 77 IVF/ICSI cycles within#10; the same period of time, at the same clinic and without previous ovarian surgery or endometriosis were studied as a control group. Patients were matched for age and treatment performed. Patients 35 years with previous ovarian surgery needed more ampoules for ovulation induction (P = 0.017) and had fewer follicles and oocytes than women in the control group (P = 0.001). Duration of folliculogenesis was similar in both groups, as was fertilization rate. A total of 10 patients achieved pregnancy in the study group (34.5%) and 14 (48.3%) in the control group. Although a lower pregnancy rate was observed in patients who had undergone previous ovarian surgery, this difference was not statistically significant (P = 0.424). In conclusion, ovarian surgery for the treatment of endometriosis reduces the ovarian outcome in IVF/ICSI cycles in women >35 years old, and might also decrease pregnancy rates. Therefore, for infertile patients, non-surgical treatment might be a better option to avoid reduction of the ovarian response.

Robotic colorectal surgery continues to rise in popularity, but there remains little evidence on the stress response following the procedure. The aim of this study was to evaluate the inflammatory response to robotic colorectal surgery and compare it with the response generated by open colorectal surgery. This was a prospective nonrandomized comparative study involving 61 patients with colorectal cancer. The evaluation of inflammatory response to either robotic or open colorectal surgery was expressed as changes in interleukin-1β, interleukin-1 receptor antagonist, interleukin-6, tumor necrosis factor-α, C-reactive protein, and procalcitonin during the first three postoperative days. Of the 61 patients, 33 underwent robotic colorectal surgery while 28 had open colorectal surgery. Groups were comparable with respect to age, sex, BMI, cancer stage, and type of resection. The relative increase of interleukin-1 receptor antagonist at 8 h postoperative, compared to baseline, was higher in the open group (P = 0.006). The decrease of interleukin-1 receptor antagonist on postoperative days 1 and 3, compared to the maximum at 8 h, was more pronounced in the open group than in the robotic group (P = 0.008, P = 0.006, respectively), and the relative increase of interleukin-6 at 8 h after incision was higher in the open group (P = 0.007). The relative increase of procalcitonin on postoperative days 1 and 3 was higher in the open group than the robotic group (P < 0.001, P = 0.004, respectively). This study shows that when compared with open colorectal surgery, robotic colorectal surgery results in a less pronounced inflammatory response and more pronounced anti-inflammatory action.

The aim of this study was to determine whether changes to referral protocols for cardiac surgery have had an impact on waiting times, hospitalizations and mortality during the waiting period and during the first year of follow-up after surgery. In this retrospective study of patients referred for cardiac surgery between January 1, 2008 and September 30, 2014, the study population was divided into two groups: those referred before (group A, January 1, 2008 to August 31, 2011) and after (group B, September 1, 2011 to September 30, 2014) the change in referral protocols. A telephone follow-up was conducted. There were 864 patients referred for cardiac surgery, 557 in group A and 307 in group B. Patient characteristics were similar between groups. The mean waiting time for surgery was 10.6±18.5 days and 55.7±79.9 days in groups A and B, respectively (p=0.00). During the waiting period two patients (0.4%) were hospitalized in group A and 28 (9.1%) in group B (p=0:00); mortality was, respectively, 0% and 2.3% (p=0.00). During one-year follow-up 12.8% of group A patients and 16% of group B patients were hospitalized. Cardiovascular mortality in this period was around 5% in both groups (p>0.05). Changes to referral protocols for cardiac surgery had an impact on waiting times, on the number of hospitalizations and on mortality in this period.

This study compared the total joint arthroplasty (TJA) surgical outcomes of patients who had bariatric surgery prior to TJA to TJA patients who were candidates but did not have bariatric surgery. Patients were retrospectively grouped into: Group 1 (n=69), those with bariatric surgery >2 years prior to TJA, Group 2 (n=102), those with surgery within 2 years of TJA, and Group 3 (n=11,032), those without bariatric surgery. In Group 1, 2.9% (95%CI 0.0–6.9%) had complications within 1 year compared to 5.9% (95%CI 1.3–10.4%) in Group 2, and 4.1% (95%CI 3.8–4.5%) in Group 3. 90-day readmission (7.2%, 95%CI 1.1–13.4%) and revision density (3.4/100 years of observation) was highest in Group 1. Bariatric surgery prior to TJA may not provide dramatic improvements in post-operative TJA surgical outcomes. PMID:24674730

Patient-reported outcome measures reveal the quality of surgical care from the patient's perspective. We aimed to compare body image, self-esteem, hospital anxiety and depression, and cosmetic outcomes by using validated tools between patients undergoing robot-assisted surgery and those undergoing conventional open surgery. This single-center, multidisciplinary, randomized, prospective study of 62 patients who underwent cardiac surgery was conducted at Hospital from May 2013 to January 2015. The patients were divided into two groups: the robotic group (n = 33) and the open group (n = 29). The study employed five different tools to assess body image, self-esteem, and overall patient-rated scar satisfaction. There were statistically significant differences between the groups in terms of self-esteem scores (p = 0.038), body image scores (p = 0.026), overall Observer Scar Assessment Scale (p = 0.013), and overall Patient Scar Assessment Scale (p = 0.036) scores in favor of the robotic group during the postoperative period. Robot-assisted surgery protected the patient's body image and self-esteem, while conventional open surgery decreased these levels but without causing pathologies. Preoperative depression and anxiety level was reduced by both robot-assisted surgery and conventional open surgery. The groups did not significantly differ on Patient Satisfaction Scores and depression/anxiety scores. The results of this study clearly demonstrated that a minimally invasive approach using robotic-assisted surgery has advantages in terms of body image, self-esteem, and cosmetic outcomes over the conventional approach in patients undergoing cardiac surgery.

Ambulatory cleft lip repair after its acceptance in developed countries is also becoming popular in developing world. This study was performed to compares the outcomes of ambulatory cleft lip repair with the inpatient group for adult patients. Objectives were to compare outcome after ambulatory and inpatient cleft lip surgery for adults with respect to perioperative complications (Early: pain, oedema of upper lip, bleeding, nausea or vomiting, infection, dehiscence; Late: visible scar and white roll discrepancy), to compare the economic benefits, and evaluate patient satisfaction in terms of acceptance for ambulatory surgery. This comparative study is carried out in Plastic Surgery Department, King Edward Medical University, Mayo Hospital, Lahore. The study included 80 adult patients fulfilling inclusion criteria and were randomly divided into two groups, i.e., Ambulatory (Group-A, n=40) and Inpatient (Group-B, n=40). Those belonging to ambulatory group were worked up on OPD basis, advised to report on morning of surgery, operated under loco-regional anaesthesia and were discharged on same day. Patients of inpatient group were admitted two days before surgery, worked up in ward, operated under general anaesthesia and were discharged on 2nd day. Ambulatory cleft lip surgery can be easily performed under loco-regional anaesthesia. Perioperative complications between these groups were comparable. Hospital stay was significantly reduced in ambulatory surgery. The patients felt more satisfied after ambulatory than inpatient surgery. Ambulatory cleft lip repair for adults is as safe as inpatient surgery. It is dependable option and can be successfully performed in our setup. It should be considered whenever possible due to cost effectiveness, reduction of waiting lists, earlier discharge and better utilisation of hospital resources.

Throat packs are commonly used to prevent ingestion or aspiration of blood and other debris during cleft lip/palate surgery. However, dislodgement or (partial) retainment after extubation could have serious consequences. The aim of the present study was to investigate the effect of omitting pharyngeal packing during cleft lip/palate surgery on the incidence of early postoperative complications in children. A retrospective study was performed on all children who underwent cleft lip/palate surgery at the Wilhelmina Children's Hospital. This study compared the period January 2010 through December 2012 when pharyngeal packing was applied according to local protocol (group A) with the period January 2013 till December 2015 when pharyngeal packing was no longer applied after removal from the protocol (group B). Data were collected for sex, age at operation, cleft lip/palate type, type of repair, lateral incisions, length of hospital stay, and complications in the first 6 weeks after surgery. Early complications included wound dehiscence, postoperative bleeding, infection, fever, upper respiratory tract infection (URTI), and lower respiratory tract infection (LRTI). This study included 489 cleft lip/palate operations (group A n = 246, group B n = 243). A total of 39 (15.9%) early complications were recorded in group A and a total of 40 (16.5%) in group B. There were no significant differences (P = 0.902) in complications between the two groups; however, there was a significant difference (P < 0.001) in length of hospital stay between the two groups (group A 3.6 days vs group B 3.2 days). Omitting routine placement of throat packs in cleft lip/palate surgery was not associated with an increased early postoperative complication rate. Therefore, the traditional, routine placement of a throat pack during cleft lip/palate surgery can be questioned. The traditional, routine placement of a throat pack during cleft lip/palate surgery can be questioned.

Laparoscopic surgery has become a popular surgical tool when compared to traditional open surgery. There are limited data on pediatric patients regarding whether pneumoperitoneum affects cerebral oxygenation although end-tidal CO2 concentration remains normal. Therefore, this study was designed to evaluate the changes of cerebral oxygen saturation using near-infrared spectroscope during laparoscopic surgery in children. The study comprised forty children who were scheduled for laparoscopic (Group L, n=20) or open (Group O, n=20) appendectomy. Hemodynamic variables, right and left regional cerebral oxygen saturation (RrSO2 and LrSO2), fraction of inspired oxygen, end-tidal carbon dioxide pressure (PETCO2), peak inspiratory pressure (Ppeak), respiratory minute volume, inspiratory and end-tidal concentrations of sevoflurane and body temperature were recorded. All parameters were recorded after anesthesia induction and before start of surgery (T0, baseline), 15min after start of surgery (T1), 30min after start of surgery (T2), 45min after start of surgery (T3), 60min after start of surgery (T4) and end of the surgery (T5). There were progressive decreases in both RrSO2 and LrSO2 levels in both groups, which were not statistically significant at T1, T2, T3, T4. The RrSO2 levels of Group L at T5 were significantly lower than that of Group O. One patient in Group L had an rSO2 value <80% of the baseline value.

Study Design Retrospective study. Purpose In this study, we compared the postoperative outcomes of extreme lateral interbody fusion (XLIF) indirect decompression with that of mini-open transforaminal lumbar interbody fusion (TLIF) in patients with lumbar degenerative spondylolisthesis. Overview of Literature There are very few reports examining postoperative results of XLIF and minimally invasive TLIF for degenerative lumbar spondylolisthesis, and no reports comparing XLIF and mini-open TLIF. Methods Forty patients who underwent 1-level spinal fusion, either by XLIF indirect decompression (X group, 20 patients) or by mini-open TLIF (T group, 20 patients), for treatment of lumbar degenerative spondylolisthesis were included in this study. Invasiveness of surgery was evaluated on the basis of surgery time, blood loss, hospitalization period, and perioperative complications. The Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ), disc angle (DA), disc height (DH), and slipping length (SL) were evaluated before surgery, immediately after surgery, and at 12 months after surgery. Cross-sectional spinal canal area (CSA) was also measured before surgery and at 1 month after surgery. Results There was no significant difference between the groups in terms of surgery time or hospitalization period; however, X group showed a significant decrease in blood loss (p<0.001). Serious complications were not observed in either group. In clinical assessment, no significant differences were observed between the groups with regard to the JOABPEQ results. The change in DH at 12 months after surgery increased significantly in the X group (p<0.05), and the changes in DA and SL were not significantly different between the two groups. The change in CSA was significantly greater in the T group (p<0.001). Conclusions Postoperative clinical results were equally favorable for both procedures; however, in comparison with mini-open TLIF, less blood loss and greater correction of DH were observed in XLIF.

Surgeries may trigger the stress response which leads to changes in blood glucose level, and studies suggest that different sedation and anesthesia methods have different effects on blood glucose level. The aim of this study was to investigate changes of blood glucose levels in diabetic patients and compare them in two sedation methods of propofol + fentanyl and midazolam + fentanyl. Totally, 80 diabetic candidates for cataract surgery who had all the inclusion criteria, underwent cataract surgery using two methods of propofol (1 mg/kg/h) + fentanyl (2 μg/kg) (Group P) and midazolam (0.03 mg/kg) + fentanyl (2 μg/kg) (Group M) for light sedation. In the end, 70 patients (Group P n = 35 and Group M n = 35) remained in the study. Patients' blood glucose levels, vital signs, and hemodynamic data were assessed 30 min prior to the surgery, each 15 min during surgery and at the end of surgery. Hemodynamic parameters did not have a statistically significant difference between the two groups mean blood glucose level in Group M was 149.15 mg/dl and in Group P was 149.2 mg/dl, and based on repeated measures analysis of variance test, significant differences were not observed between the two groups (P = 0.99). T-test showed no significant differences in the blood glucose level at any time of the study between the two groups. Light sedation methods of propofol + fentanyl and midazolam + fentanyl did not have any differences in alteration of blood glucose level.

Robotic surgery is a rapidly growing area in surgery. In an era of emphasis on cost reduction, the question becomes how do you train residents in robotic surgery? The aim of this study was to determine if there was a difference in operative time and complications when comparing general surgery residents learning robotic cholecystectomies to those learning standard laparoscopic cholecystectomies. A retrospective analysis of adult patients undergoing robotic and laparoscopic cholecystectomy by surgical residents between March 2013 and February 2014 was conducted. Demographic data, operative factors, length of stay (LOS), and complications were examined. Univariate and multivariate analyses were performed. The significance was set at p < 0.05. A total of 58 patients were included in the study (18 in the robotic cholecystectomy group and 40 in the laparoscopic group). Age, diagnosis, and American Society of Anesthesiologists score were not significantly different between groups. There was only 1 complication in the standard laparoscopic group in which a patient had to be taken back to surgery because of an incarcerated port site. LOS was significantly higher in the standard laparoscopic group (mean = 2.28) than in the robotic group (mean = 0.56; p < 0.0001). Operating room (OR) time was not statistically different between the standard laparoscopic group (mean = 90.98 minutes) and the robotic group (mean = 97.00 minutes; p = 0.4455). When intraoperative cholangiogram was evaluated, OR time was shorter in the robotic group. Robotic training in general surgery residency does not amount to extra OR time. LOS in our study was significantly longer in the standard laparoscopic group. Copyright © 2015 Association of Program Directors in Surgery. Published by Elsevier Inc. All rights reserved.

In this study, we aim to evaluate the effectiveness and safety of PNL in patients with a history of open renal surgery or PNL by comparing with primary patients and to compare impact of previous open renal surgery and PNL on the success and complications of subsequent PNL. Charts of patients, who underwent PNL at our institute, were analyzed retrospectively. Patients were divided into three groups according to history of renal stone surgery. Patients without history of renal surgery were enrolled into Group 1. Other patients with previous PNL and previous open surgery were categorized as Group 2 and Group 3. Preoperative characteristic, perioperative data, stone-free status, and complication rates were compared between the groups. Stone-free status was accepted as completing clearance of stone and residual fragment smaller than 4 mm. Eventually, 2070 patients were enrolled into the study. Open renal surgery and PNL had been done in 410 (Group 2) and 131 (Group 3) patients, retrospectively. The mean operation time was longer (71.3 ± 33.5 min) in Group 2 and the mean fluoroscopy time was longer (8.6 ± 5.0) in Group 3 but there was no statistically significant difference between the groups. Highest stone clearance was achieved in primary PNL patients (81.62%) compared to the other groups (77.10% in Group 2 and 75.61% in Group 3). Stone-free rate was not significantly different between Group 2 and Group 3. Fever, pulmonary complications, and blood transfusion requirement were not statically different between groups but angioembolization was significantly higher in Group 2. Percutaneous nephrolithotomy is a safe and effective treatment modality for patients with renal stones regardless history of previous PNL or open renal surgery. However, history of open renal surgery but not PNL significantly reduced PNL success.

Abstract Backgroud: This study aimed to investigate the protective effect of intraoperative used hydroxypropyl methylcellulose (HPMC 2%) on the ocular surface after cataract surgery. Methods: A total of 149 eyes (149 patients) diagnosed with age-related cataract, age 69.19 ± 9.74 years, were enrolled in this prospective, parallel-design, continuous, randomised controlled study. Patients were randomly assigned to receive HPMC 2% (study group) or balanced salt solution (control group) during the surgery to moisturize the cornea surface. The Ocular Surface Disease Index, Schirmer test without topical anesthetics, tear break-up time, and corneal fluorescein staining were assessed preoperatively, 1 day, 1 week, and 1 month after the surgery, respectively. Results: The Schirmer test value of male patients in the study group at 1 week postoperation was higher than that of male patients in the control group (P = .019). For patients diagnosed with dry eye before the surgery, Schirmer test value in the male patients in the study group at 1 month after surgery was higher than that in the male patients in the control group (P = .037). Furthermore, for the cluster of preoperative dry eye patients whose surgical time was longer than median, corneal fluorescein staining of the patients in the study group was superior to that of the patients in the control group (P = .032). Conclusion: Intraoperative use of HPMC 2% on the cornea surface could improve clinical outcomes of tear film and ocular surface health to some degree, especially in the patients diagnosed with dry eye before the surgery, male patients, and patients whose surgical time was relatively longer.

The aim of the present study is to compare piezoelectric surgery to the conventional rotatory surgery in mandibular cyst enucleation, and to determine the 2 method's suitability and the postoperative outcomes. Eighty patients were included in the study. 35 male and 45 female, which showed cystic mandibular lesions, compared with the inferior alveolar nerve or the mental nerve. The patients were randomly divided into two groups. In the test group, cystectomy was performed using conventional rotatory instrumentation (rotatory-group), and in the other one piezoelectric surgery (piezo-group). The swelling was documented 24/48/72 h and 1 week post-surgery and the patients recorded their subjective postoperative pain daily for 7 days using a Visual Analog Scale (VAS). Patients treated with piezoelectric technique have presented a lower VAS, minor swelling and less recovery time compared to the rotatory-group. No lesions of the mandible nerve were detected with piezosurgery whereas surgery with rotary instruments resulted in 8% hypesthesia at least up to one week. The results of this study suggest that piezosurgery may be considered effective in cyst enucleation compared to traditional procedures with burs, since it grants the patients significantly less post-surgical pain and swelling.

Neoadjuvant therapy-induced immunological deterioration may be a key factor in postoperative morbidity in patients with esophageal cancer. This study aimed to determine the effects of perioperative feeding with an immuno-enhanced diet on immune competence in patients treated with neoadjuvant therapy followed by surgery. Because an immuno-enhanced diet that contained several antioxidants was used, perioperative oxidative stress and the effects of the immuno-enhanced diet on this stress were also investigated. Of 39 patients with esophageal cancer who underwent similar surgical procedures, 26 patients who received chemotherapy or chemoradiation therapy before surgery were randomly divided into two groups: group 1 (n= 14) was given an immuno-enhanced diet for 5 days before surgery, and group 2 (n= 12) received no enteral feeding products before surgery. Group 3 (n= 13) consisted of patients that did not receive neoadjuvant therapy and received no enteral feeding products before surgery. Several markers for coagulation and fibrinolysis were determined and immunological assessments were performed for each patient. To measure reactive oxygen metabolites and the total antioxidant capacity, diacron-reactive oxygen metabolites (d-ROMs) and OXY-adsorbent tests were performed using a free radical elective evaluator. Significant depression in lymphocyte numbers was observed in groups 1 and 2 before and early after surgery as compared to group 3. Numbers of B cells, CD4/CD8 ratio, and phytohemagglutinin-induced lymphocyte transformation tests were also significantly decreased in groups 1 and 2 on postoperative day 1. Fibrin and fibrinogen degradation products were significantly elevated in group 2 compared to group 1. d-ROMs and OXY-adsorbent test values were elevated before surgery and were decreased transiently early after surgery. Compared to groups 2 and 3, d-ROMs values were significantly lower in group 1 patients throughout the postoperative period, while OXY-adsorbent test values were significantly higher in group 2 patients. Oxidative index was significantly suppressed in group 1 compared to group 3. No significant intergroup differences were observed with regard to morbidity after surgery. Although the baseline levels of immunological function might have been different because of less-advanced cancer stages in group 3, neoadjuvant therapy significantly affected several immunological parameters. Preoperative administration of an immuno-enhanced diet did not significantly prevent neoadjuvant therapy-induced immunological deterioration prior to esophageal cancer surgery. Patients with esophageal cancer had elevated levels of oxidant and antioxidant activities before surgery, which were transiently decreased early after surgery. Although the underlying mechanisms for these perioperative changes are unclear, this study showed that an immuno-enhanced diet containing several antioxidants may reduce oxidative stress following esophageal cancer surgery. After these mechanisms are studied further, oxidative stress control may become another tool for perioperative management to reduce morbidity after esophageal cancer surgery. © 2011 Copyright the Authors.

Combined surgery versus cataract surgery alone for eyes with cataract and glaucoma

Zhang, Mingjuan Lisa; Hirunyachote, Phenpan; Jampel, Henry

2016-01-01

Background Cataract and glaucoma are leading causes of blindness worldwide, and their co-existence is common in elderly people. Glaucoma surgery can accelerate cataract progression, and performing both surgeries may increase the rate of postoperative complications and compromise the success of either surgery. However, cataract surgery may independently lower intraocular pressure (IOP), which may allow for greater IOP control among patients with co-existing cataract and glaucoma. The decision between undergoing combined glaucoma and cataract surgery versus cataract surgery alone is complex. Therefore, it is important to compare the effectiveness of these two interventions to aid clinicians and patients in choosing the better treatment approach. Objectives To assess the relative effectiveness and safety of combined surgery versus cataract surgery (phacoemulsification) alone for co-existing cataract and glaucoma. The secondary objectives include cost analyses for different surgical techniques for co-existing cataract and glaucoma. Search methods We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (2014, Issue 10), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to October 2014), EMBASE (January 1980 to October 2014), PubMed (January 1948 to October 2014), Latin American and Caribbean Health Sciences Literature Database (LILACS) (January 1982 to October 2014), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov), and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 3 October 2014. We checked the reference lists of the included trials to identify further relevant trials. We used the Science Citation Index to search for references to publications that cited the studies included in the review. We also contacted investigators and experts in the field to identify additional trials. Selection criteria We included randomized controlled trials (RCTs) of participants who had open-angle, pseudoexfoliative, or pigmentary glaucoma and age-related cataract. The comparison of interest was combined cataract surgery (phacoemulsification) and any type of glaucoma surgery versus cataract surgery (phacoemulsification) alone. Data collection and analysis Two review authors independently assessed study eligibility, collected data, and judged risk of bias for included studies. We used standard methodological procedures expected by the Cochrane Collaboration. Main results We included nine RCTs, with a total of 655 participants (657 eyes), and follow-up periods ranging from 12 to 30 months. Seven trials were conducted in Europe, one in Canada and South Africa, and one in the United States. We graded the overall quality of the evidence as low due to observed inconsistency in study results, imprecision in effect estimates, and risks of bias in the included studies. Glaucoma surgery type varied among the studies: three studies used trabeculectomy, three studies used iStent® implants, one study used trabeculotomy, and two studies used trabecular aspiration. All of these studies found a statistically significant greater decrease in mean IOP postoperatively in the combined surgery group compared with cataract surgery alone; the mean difference (MD) was -1.62 mmHg (95% confidence interval (CI) -2.61 to -0.64; 489 eyes) among six studies with data at one year follow-up. No study reported the proportion of participants with a reduction in the number of medications used after surgery, but two studies found the mean number of medications used postoperatively at one year was about one less in the combined surgery group than the cataract surgery alone group (MD -0.69, 95% CI -1.28 to -0.10; 301 eyes). Five studies showed that participants in the combined surgery group were about 50% less likely compared with the cataract surgery alone group to use one or more IOP-lowering medications one year postoperatively (risk ratio (RR) 0.47, 95% CI 0.28 to 0.80; 453 eyes). None of the studies reported the mean change in visual acuity or visual fields. However, six studies reported no significant differences in visual acuity and two studies reported no significant differences in visual fields between the two intervention groups postoperatively (data not analyzable). The effect of combined surgery versus cataract surgery alone on the need for reoperation to control IOP at one year was uncertain (RR 1.13, 95% CI 0.15 to 8.25; 382 eyes). Also uncertain was whether eyes in the combined surgery group required more interventions for surgical complications than those in the cataract surgery alone group (RR 1.06, 95% CI 0.34 to 3.35; 382 eyes). No study reported any vision-related quality of life data or cost outcome. Complications were reported at 12 months (two studies), 12 to 18 months (one study), and two years (four studies) after surgery. Due to the small number of events reported across studies and treatment groups, the difference between groups was uncertain for all reported adverse events. Authors' conclusions There is low quality evidence that combined cataract and glaucoma surgery may result in better IOP control at one year compared with cataract surgery alone. The evidence was uncertain in terms of complications from the surgeries. Furthermore, this Cochrane review has highlighted the lack of data regarding important measures of the patient experience, such as visual field tests, quality of life measurements, and economic outcomes after surgery, and long-term outcomes (five years or more). Additional high-quality RCTs measuring clinically meaningful and patient-important outcomes are required to provide evidence to support treatment recommendations. PMID:26171900

This study examined the effects of previous ovarian surgery on the clinical response to ovulation induction with clomiphene citrate-human menopausal gonadotropin in an in vitro fertilization program. Patients were divided into five clinical groups: group A (n = 63), no previous ovarian surgery; B (n = 9), unilateral cystectomy; C (n = 6), unilateral oophorectomy with no contralateral ovarian surgery; D (n = 7), bilateral ovarian surgery with both ovaries present; and E (n = 4), unilateral oophorectomy and contralateral cystectomy. Patients in group E demonstrated significantly lower serum estradiol on cycle days 9-11 (P less than or equal to .05) and fewer follicles on cycle days 11-12 (P less than or equal to .05) than did patients in groups A-D. The percentage of cancelled cycles increased with increasing amounts of ovarian surgery (P less than or equal to .03). The study suggests that one cause of a poor response to ovulation induction for in vitro fertilization may be prior extensive ovarian surgery.

To investigate the non-inferiority of postoperative single-dose intravenous antimicrobial prophylaxis to multiple-dose intravenous antimicrobial prophylaxis in terms of the incidence of surgical site infections (SSIs) in patients undergoing elective rectal cancer surgery by a prospective randomized study. Patients undergoing elective surgery for rectal cancer were randomized to receive a single intravenous injection of flomoxef (group 1) or five additional doses (group 2) of flomoxef after the surgery. All the patients had received preoperative oral antibiotic prophylaxis (kanamycin and erythromycin) after mechanical cleansing within 24 h prior to surgery, and had received intravenous flomoxef during surgery. A total of 279 patients (including 139 patients in group 1 and 140 in group 2) were enrolled in the study. The incidence of SSIs was 13.7% in group 1 and 13.6% in group 2 (difference [95% confidence interval]: -0.2% [-0.9 to 0.7%]). The incidence of SSIs was not significantly different in patients undergoing elective rectal surgery who were treated using a single dose of postoperative antibiotics compared to those treated using multiple-dose antibiotics when preoperative mechanical and chemical bowel preparations were employed.

Body dysmorphic disorder among patients referring for cosmetic surgeries is a disorder that if not diagnosed by a physician, can cause irreparable damage to the doctor and the patient. The aim of this study was to compare body image concern in candidates for rhinoplasty and therapeutic surgery. This was a cross-sectional study conducted on 212 patients referring to Loghman Hospital of Tehran for rhinoplasty and therapeutic surgery during the period from 2014 through 2016. For each person in a cosmetic surgery group, a person of the same sex and age in a therapeutic surgery group was matched, and the study was conducted on 60 subjects in the rhinoplasty group and 62 patients in the therapeutic surgery group. Then, the Body Image Concern Inventory and demographic data were filled by all patients and the level of body image concern in both groups was compared. Statistical analysis was conducted using SPSS 16, Chi-square test as well as paired-samples t-test. P-value of less than 0.05 was considered statistically significant. In this study, 122 patients (49 males and 73 females) with mean age of 27.1±7.3 between 18 and 55 years of age were investigated. Sixty subjects were candidates for rhinoplasty and 62 subjects for therapeutic surgery. Candidates for rhinoplasty were mostly male (60%) and single (63.3%). Results of the t-test demonstrated that body image concern and body dysmorphic disorder were higher in the rhinoplasty group compared to the therapeutic group (p<0.05). Results of this study showed that the frequency of rhinoplasty candidates is higher in single male subjects. In addition, body image concern was higher in rhinoplasty candidates compared to candidates for other surgeries. Visiting and correct interviewing of people who referred for rhinoplasty is very important to measure their level of body image concern to diagnose any disorders available and to consider required treatments.

The high frequency of surgical site infections (SSIs) after hepato-pancreato-biliary (HPB) surgery is a problem that needs to be addressed. This prospective, randomized, controlled study examined whether perioperative prophylactic use of antibiotics based on preoperative bile culture results in HPB surgery could decrease SSI. Participants comprised 126 patients who underwent HPB (bile duct, gallbladder, ampullary, or pancreatic) cancer surgery with biliary reconstruction at Hokkaido University Hospital between August 2008 and March 2013 (UMIN Clinical Trial Registry #00001278). Before surgery, subjects were randomly allocated to a targeted group administered antibiotics based on bile culture results or a standard group administered cefmetazole. The primary endpoint was SSI rates within 30 days after surgery. Secondary endpoint was SSI rates for each operative procedure. Of the 126 patients, 124 were randomly allocated (targeted group, n = 62; standard group, n = 62). Frequency of SSI after surgery was significantly lower in the targeted group (27 patients, 43.5%) than in the standard group (44 patients, 71.0%; P = 0.002). Among patients who underwent pancreaticoduodenectomy and hepatectomy, SSI occurred significantly less frequently in the targeted group (P = 0.001 and P = 0.025, respectively). This study demonstrated that preoperative bile culture-targeted administration of prophylactic antibiotics decreased SSIs following HBP surgery with biliary reconstruction. © 2017 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

Esophagectomy and definitive chemoradiotherapy are recognized standard initial treatment modalities for cervical esophageal cancer. The goal of this study was to compare the treatment outcomes of curative surgery with those of chemoradiotherapy in patients who had potentially resectable tumor and who were candidates for surgery. We evaluated the data from 49 consecutive patients who were diagnosed with potentially resectable cervical esophageal cancer and who were deemed candidates for surgery. Thirteen patients were included in the surgery group, and 36 patients were included in chemoradiotherapy group. Baseline characteristics were balanced between the two groups. In the chemoradiotherapy group, the complete response rate was 58.3%. There was no significant difference in 5-year overall survival when comparing the surgery group and the chemoradiotherapy group (surgery, 60.6%; chemoradiotherapy, 51.4%; P = 0.89). In the chemoradiotherapy group, of the 15 patients who failed to respond to initial treatment, 11 patients subsequently underwent salvage surgery. In conclusion, curative surgery and chemoradiotherapy as initial treatment for cervical esophageal cancer have comparable survival outcomes. Chemoradiotherapy should be selected as the initial larynx-preserving treatment for patients with cervical esophageal cancer although chemoradiotherapy non-responders require additional treatment, including salvage surgery. © 2016 International Society for Diseases of the Esophagus.

To examine the effects of aromatherapy massage on anxiety and sleep quality in patients undergoing colorectal surgery in the preoperative period. In recent years, there has been an increase in the number of studies conducted on aromatherapy massage. It is stated that studies conducted on aromatherapy massage for anxiety and sleep quality reveal contradictory results and that more research is required on the issue. A randomized controlled trial. Eighty patients undergoing colorectal surgery were randomly assigned to experimental and control group. To the experimental group (n = 40), aromatherapy massage was applied in accordance with the "Back Massage Guide" using 5% lavender oil (Lavandula Hybrida) for ten minutes before surgery and the morning of surgery. The control group received standard nursing care in compliance with the hospital procedure. Data were obtained by the State Anxiety Inventory (SAI) and Richard-Campbell Sleep Questionnaire (RCSQ). Results were analyzed using the t-test, Chi-square test or Fisher's exact test. There was no baseline difference between the groups. A statistically significant difference was found between the experimental and control group in terms of the SAI and RCSQ mean scores recorded on the morning of surgery. It was determined that the SAI and RCSQ mean score of the experimental group after aromatherapy massage on the morning of surgery decreased when compared to that of the evening before surgery. It was found that aromatherapy massage with lavender oil increased the sleep quality and reduced the level of anxiety in patients with colorectal surgery in the preoperative period.

Our study is a prospective, randomized study on patients undergoing arthroscopic shoulder surgery in the beach-chair position to evaluate the effects of positive end-expiratory pressure (PEEP) on hemodynamic stability, providing a bloodless surgical field and surgical satisfaction. Fifty patients were divided into two groups. Group I (n=25) had zero end-expiratory pressure (ZEEP) administered under general anesthesia, and group II (n=25) had +5 PEEP administered. During surgery, intraarticular hemorrhage and surgical satisfaction were evaluated on a scale of 0-10. During surgery, at the 5th, 30th, 60th, and 90th minutes and at the end of surgery, heart rate, mean arterial pressure (MAP), and positive inspiratory pressure were recorded. At the end of the surgery, the amount of bleeding and duration of the operation were recorded. In group I, the duration of operation and amount of bleeding were found to be significantly greater than those in group II (p<0.05). The surgical satisfaction score and clarity of the surgical field were found to be significantly lower in group I than in group II (p<0.05). MAP values in group I were significantly lower than those in group II. The SPO² values in group I were significantly lower than those in group II. Adding PEEP to the ventilation parameters of arthroscopic shoulder surgery in the beach-chair position reduces the amount of hemorrhage in the surgical field and thus increases surgical satisfaction without requiring the creation of controlled hypotension.

Clinical use of an adhesion barrier made of oxidized, regenerated cellulose, Interceed®, has been reported in the field of obstetrics and gynecology to help prevent adhesions between the peritoneum and the bowel in various types of operations. In gastrointestinal surgery, sodium hyaluronate/carboxymethylcellulose has been reported as an absorbable membrane to reduce postoperative adhesions. The present study was a prospective randomized controlled study to investigate the safety and usefulness of Interceed in laparoscopic colorectal surgery. We analyzed 99 patients who underwent laparoscopic colorectal surgery from 2013 to 2014. The patients were randomly allocated to the group that used Interceed (Interceed group) or the group that did not (Non-Interceed group). Fifty cases used Interceed, and 49 cases did not. The incidence of adverse events was 12.0% in the Interceed group and 16.3% in the Non-Interceed group (P = 0.58). There were no significant differences, and no adhesive bowel obstructions were observed in the Interceed group. We have shown that using Interceed in laparoscopic colorectal surgery is valid and technically safe. © 2016 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

Vulvar intraepithelial neoplasia (VIN) is a premalignant lesion of the vulva. The incidence of VIN is increasing. The surgery is currently the gold standard therapy for VIN, but Imiquimod could be a completion to surgery. The aim of this study is to compare the overall complete response, the recurrence rate and the risk factors for recurrence among two groups of patients: women with high grade VIN underwent surgery and patients treated with surgery plus Imiquimod. 80 patients with histologically diagnosed VIN 2/3 were enrolled in this prospective study. Our patients were divided into two groups: 40 women underwent surgery (A) and 40 patients were treated with surgery plus Imiquimod (B). All women had a 5-year follow-up. Recurrence rate and complete response were evaluated. The following patients' characteristics were analyzed: smoke, multifocal disease, multicentric disease, degree of the lesion. In the group A recurrence rate was 44.8%, in the group B it was 48.4%. In both groups the presence of multifocal lesions (p = 0.02) and VIN 3 (p = 0.006) before treatment was associated with a higher risk of recurrence. This study found that surgery remains the principal approach for VIN with regard to relapse and complete response since the treatment with Imiquimod associated with surgery didn't show a lower recurrence rate. Although the surgical treatments remain the best therapeutic option for VIN with regard to recurrence and overall complete response, the combined therapy seems to be an interesting modality, but further studies are needed.

Surgery for cataracts in people with age-related macular degeneration

Background Cataract and age-related macular degeneration (AMD) are common causes of decreased vision that often occur simultaneously in people over age 50. Although cataract surgery is an effective treatment for cataract-induced visual loss, some clinicians suspect that such an intervention may increase the risk of worsening of underlying AMD and thus have deleterious effects on vision. Objectives The objective of this review was to evaluate the effectiveness and safety of cataract surgery compared with no surgery in eyes with AMD. Search methods We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 11), Ovid MEDLINE, Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Ovid MEDLINE Daily (January 1946 to December 2016), Embase (January 1980 to December 2016), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982to December 2016), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov), and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 2 December 2016. Selection criteria We included randomized controlled trials (RCTs) and quasi-randomized trials that enrolled participants whose eyes were affected by both cataract and AMD in which cataract surgery was compared with no surgery. Data collection and analysis Two review authors independently evaluated the search results against the inclusion and exclusion criteria. Two review authors independently extracted data, assessed risk of bias for included studies, and graded the certainty of evidence. We followed methods as recommended by Cochrane. Main results We included two RCTs with a total of 114 participants (114 study eyes) with visually significant cataract and AMD. We identified no ongoing trials. Participants in each RCT were randomized to immediate cataract surgery (within two weeks of enrollment) or delayed cataract surgery (six months after enrollment). The risk of bias was unclear for most domains in each study; one study was registered prospectively. In one study conducted in Australia outcomes were reported only at six months (before participants in the delayed-surgery group had cataract surgery). At six months, the immediate-surgery group showed mean improvement in best-corrected visual acuity (BCVA) compared with the delayed-surgery group (mean difference (MD) -0.15 LogMAR, 95% confidence interval (CI) -0.28 to -0.02; 56 participants; moderate-certainty evidence). In the other study, conducted in Austria, outcomes were reported only at 12 months (12 months after participants in the immediate-surgery group and six months after participants in the delayed-surgery group had cataract surgery). There was uncertainty as to which treatment group had better improvement in distance visual acuity at 12 months (unit of measure not reported; very low-certainty evidence). At 12 months, the mean change from baseline between groups in cumulated drusen or geographic atrophy area size was small and there was uncertainty which, if either, of the groups was favored (MD 0.76, 95% CI -8.49 to 10.00; 49 participants; low-certainty evidence). No participant in one study had exudative AMD develop in the study eye during 12 months of follow-up; in the other study, choroidal neovascularization developed in the study eye of 1 of 27 participants in the immediate-surgery group versus 0 of 29 participants in the delayed-surgery group at six months (risk ratio 3.21, 95% CI 0.14 to 75.68; 56 participants; very low-certainty evidence). Quality of life was measured using two different questionnaires. Scores on the Impact of Vision Impairment (IVI) questionnaire suggested that the immediate-surgery group fared better regarding vision-related quality of life than the delayed-surgery group at six months (MD in IVI logit scores 1.60, 95% CI 0.61 to 2.59; low-certainty evidence). However, we could not analyze scores from the Visual Function-14 (VF-14) questionnaire from the other study due to insufficient data. No postoperative complication was reported from either study. Authors' conclusions At this time, it is not possible to draw reliable conclusions from the available data as to whether cataract surgery is beneficial or harmful in people with AMD after 12 months. Although cataract surgery provides short-term (six months) improvement in BCVA in eyes with AMD compared with no surgery, it is unclear whether the timing of surgery has an effect on long-term outcomes. Physicians must make recommendations to their AMD patients regarding cataract surgery based on experience and clinical judgment until large controlled trials are conducted and their findings published. There is a need for prospective RCTs in which cataract surgery is compared with no surgery in people with AMD to better evaluate whether cataract surgery is beneficial or harmful in all or a subset of AMD patients. However, ethical considerations preclude withholding surgery, or delaying it for several years, if it may be a potentially beneficial treatment. Designers of future trials are encouraged to utilize existing standardized systems for grading cataract and AMD and for measuring key outcomes: visual acuity, change in visual acuity, worsening of AMD, quality of life measures, and adverse events.

Background: The thought of having a surgery can be stressful for everyone. Providing the necessary information to the patient can help both the patient and the treatment team. This study was conducted to compare the effectiveness of face-to-face verbal training and educational pamphlets on the readiness of patients for undergoing non-emergency surgeries. Materials and Methods: The study was a before–after randomized clinical trial. 90 patients scheduled to undergo non-emergency surgery who referred to Shahrekord Ayatollah Kashani Hospital in 2013 were distributed randomly and gradually into two experimental groups (group of face-to-face verbal training and group of educational pamphlet) and one control group. Dependent variable of the study was pre-surgery readiness. Data analysis was carried out by using SPSS statistical software. Statistical analysis were analysis of variance (ANOVA) and correlation test. Results: Results showed that the mean scores of pre-surgery readiness in both interventional groups were significantly higher than that in the control group after the intervention (P < 0.05). However, there was no significant difference between the two experimental groups (P > 0.05). Conclusions: Each of the methods of face-to-face verbal education and using the pamphlet could be equally effective in improving the readiness of the patients undergoing surgery. Therefore, in environments where the health care providers are facing with the pressure of work and lack of sufficient time for face-to-face verbal training, suitable educational pamphlets can be used to provide the necessary information to patients and prepare them for surgery.

Objective: To evaluate the changes of adipocytokines after surgery in OSAHS patients with insulin resistance. Method: Eighty-four OSAHS patients were enrolled in this study and divided into two group based on insulin resistance: IR group(n=52) and non-IR group(n=32). All patients received UPPP surgery. The levels of chemerin,visfatin and obestatin were measured before and one week after surgery. Result: Before surgery,the levels of chemerin,visfatin and HOMA-IR in IR group were higher than those in non-IR group,while level of obestatin was lower than those in non-IR group. One week after surgery,the level of obestatin in IR group was lower than those in non-IR group. The levels of chemerin,visfatin and HOMA-IR were decreased while obestatin increased after surgery. Correlation analysis showed that UPPP surgery was negatively related with △chemerin（ r =-0.685， P <0.05）and △HOMA-IR（ r =-0.622， P <0.05）.△HOMA-IR was positively associated with △chemerin（ r =0.634， P <0.05）. Conclusion: The levels of chemerin,visfatin and obestatin are significantly improved after UPPP surgery. Level of chemerin seems to have a close relationship with IR.

Retrospective study. In this study, we compared the postoperative outcomes of extreme lateral interbody fusion (XLIF) indirect decompression with that of mini-open transforaminal lumbar interbody fusion (TLIF) in patients with lumbar degenerative spondylolisthesis. There are very few reports examining postoperative results of XLIF and minimally invasive TLIF for degenerative lumbar spondylolisthesis, and no reports comparing XLIF and mini-open TLIF. Forty patients who underwent 1-level spinal fusion, either by XLIF indirect decompression (X group, 20 patients) or by mini-open TLIF (T group, 20 patients), for treatment of lumbar degenerative spondylolisthesis were included in this study. Invasiveness of surgery was evaluated on the basis of surgery time, blood loss, hospitalization period, and perioperative complications. The Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ), disc angle (DA), disc height (DH), and slipping length (SL) were evaluated before surgery, immediately after surgery, and at 12 months after surgery. Cross-sectional spinal canal area (CSA) was also measured before surgery and at 1 month after surgery. There was no significant difference between the groups in terms of surgery time or hospitalization period; however, X group showed a significant decrease in blood loss ( p <0.001). Serious complications were not observed in either group. In clinical assessment, no significant differences were observed between the groups with regard to the JOABPEQ results. The change in DH at 12 months after surgery increased significantly in the X group ( p <0.05), and the changes in DA and SL were not significantly different between the two groups. The change in CSA was significantly greater in the T group ( p <0.001). Postoperative clinical results were equally favorable for both procedures; however, in comparison with mini-open TLIF, less blood loss and greater correction of DH were observed in XLIF.

The comparatively evaluate the three surgical treatment modalities namely cryosurgery, diode and CO2 laser surgery in terms of healing outcomes on the day of surgery, first and second week post operatively and recurrence at the end of 18 months was assessed. Thirty selected patients were divided randomly into three groups. Each group comprising of ten patients were subjected to one of the three modalities of treatment namely cryosurgery, diode laser or CO2 laser surgery for ablation of OL. Obtained data was analyzed using mainly using Chi-square and Anova tests. Study showed statistical significant differences (p > 0.05) for evaluation parameters like pain, edema and scar. The parameters like infection, recurrence, bleeding showed no statistical significance. Pain was significantly higher in CO2 laser surgery group as compared with diode laser group. There was no recurrence observed at the end of the 6 months follow up period in all the three study groups. Observations from the study highlights that all three surgical modalities used in this study were effective for treatment of OL, and the overall summation of the results of the study showed that laser therapy (CO2 and Diode) seems to offer better clinically significant results than cryotherapy. Key words: Oral premalignant lesion, leukoplakia, cryosurgery, CO2 laser surgery, diode laser surgery.

Context Extreme obesity is associated with health and cardiovascular disease risks. Although gastric bypass surgery induces rapid weight loss and ameliorates many of these risks in the short term, long-term outcomes are uncertain. Objective To examine the association of Roux-en-Y gastric bypass (RYGB) with weight loss, diabetes mellitus, and other health risks 6 years after surgery. Design, Setting, and Participants A prospective Utah-based study conducted between July 2000 and June 2011 of 1156 severely obese (body mass index [BMI] ≥35) participants aged 18–72 years (82% women; mean BMI 45.9; 95% CI, 31.2–60.6) who sought and received RYGB surgery (n=418), sought but did not have surgery (n=417; control group 1), or were randomly selected from a population-based sample not seeking weight loss surgery (n=321; control group 2). Main Outcome Measures Weight loss, diabetes, hypertension, dyslipidemia, and health-related quality of life were compared between participants having RYGB surgery and control participants using propensity score adjustment. Results Six years after surgery, patients who received RYGB surgery (with 92.6% follow-up) lost 27.7% (95% CI, 26.6%–28.9%) of their initial body weight compared with 0.2% (95% CI, -1.1% to 1.4%) gain in control group 1 and 0% (95% CI, −1.2 to 1.2%) in control group 2. Weight loss maintenance was superior in patients who received RYGB surgery, with 94% (95% CI, 92%–96%) and 76% (95% CI, 72%–81%) of patients receiving RYGB surgery maintaining at least 20% weight loss 2 and 6 years after surgery, respectively. Diabetes remission rates 6 years after surgery were 62% (95% CI, 49%–75%) in the RYGB surgery group, 8% (95% CI, 0%–16%) in control group 1, and 6% (95% CI, 0%–13%) in control group 2, with remission odds ratios (ORs) of 16.5 (95% CI, 4.7–57.6; P<.001) vs control group 1 and 21.5 (95% CI, 5.4–85.6; P<.001) vs control group 2. The incidence of diabetes throughout the course of the study was reduced after RYGB surgery (2%; 95% CI, 0%–4%; versus 17%; 95% CI, 10%–24%; OR, 0.11; 95% CI, 0.04–0.34 compared with control group 1 and 15%; 95% CI, 9%–21%; OR, 0.21; 95% CI, 0.06–0.67 compared with control group 2; both P<.001). The numbers of participants with bariatric surgery-related hospitalizations were 33 (7.9%), 13 (3.9%), and 6 (2.0%) for RYGB surgery group and 2 control groups, respectively. Conclusion Among severely obese patients, compared with nonsurgical control patients, the use of RYGB surgery was associated with higher rates of diabetes remission and lower risk of cardiovascular and other health outcomes over 6 years.

Day surgery is being more and more adopted by clinicians. Higher wavelength lasers give patients better experience than lower wavelength lasers, which makes it more suitable for day surgery. This study compares the short- and mid-term efficacy, postoperative morbidity, and patient satisfaction of "1470-nm endovenous laser ablation (EVLA) combining foam sclerotherapy in day surgery" with "810-nm EVLA with high ligation combining foam sclerotherapy in hospital surgery" on great saphenous vein (GSV) insufficiency postoperatively. A single-institution historical cohort study of 194 patients was performed in Shanghai Ninth People's Hospital, China. Ninety-seven patients received 1470-nm EVLA combining foam sclerotherapy in day surgery ("1470-nm group"), and 97 patients received 810-nm EVLA with high ligation combining foam sclerotherapy in hospital surgery recommended by guidelines ("810-nm group"). No significant difference was found between the 1470-nm group and the 810-nm group in terms of GSV occlusion rate (both 100%), complication rate, and recurrence rate (8.2 vs. 11.3%) during the period of 1-12 months after surgery. Serious complications in the 1470-nm group and 810-nm group were 0 and 1.0%. Minor complications in the 1470-nm group and 810-nm group were ecchymosis at 20.6 and 18.6%, edema at 69.1 and 63.9%, and paresthesia around ankle at 0 and 3.1%, respectively. Advantage of the 1470-nm group over the 810-nm group was statistically significant considering the patient perioperative comfort and economic cost. Treatment of 1470-nm EVLA combining foam sclerotherapy in day surgery has similar efficacy as the 810-nm EVLA with high ligation combining foam sclerotherapy in hospital surgery in GSV insufficiency and is more comfortable with less incision, hospitalization procedure, and medical costs. It may be a new option for patients who are afraid or unable to be hospitalized.

We aimed to explore the feasibility and the safety of the laparoscopic surgery for incarcerated indirect inguinal hernia (IIH) in children. From January 2012 to December 2014, 64 children were enrolled into this study. All 64 patients received laparoscopic surgery and we reviewed their perioperative and postoperative follow-up studies. In addition, we enrolled 60 cases of children who received traditional surgery of IIH administered through minimally invasive surgery as the control group. Results from the present study showed that the mean operation time for the laparoscopic group was 41.5 min (range, 15-80 min) which was significantly shorter than the control group. Nine cases developed incarcerated intestine necrosis, expanded umbilical incision and parallel resection anastomosis. They received laparoscopic hernia sac high ligation. Only 5 cases developed scrotum edema after the surgery. The postoperative length of the stay ranged from 2 to 7 days (average, 3.2). The postoperative follow-up was from 6 months to 1 year and no relapse or secondary testicular atrophy was observed in the laparoscopic group. The operation time, incidence of postoperative complications and length of stay in the laparoscopic group were decreased compared to the control group, and differences were statistically significant (P<0.05). In conclusion, laparoscopic surgery treatment for incarcerated inguinal hernia is safe and feasible and produced better results compared with the alternative.

Background and Objectives: One of the main treatment methods of coronary artery disease is coronary artery bypass graft (CABG) surgery. The anxiety level in patients undergoing this surgery is relatively very high. Thus, reducing anxiety in these patients is an important step toward wellness. This study aimed to compare the effects of peer education (PE) and orientation program (OP) on the anxiety levels of patients before CABG surgery. Material and Methods: This randomized controlled trial was conducted in 2014 at the Mazandaran Heart Center on three groups of 50 persons each: PE, OP, and control (Cl). The anxiety levels of patients in each group were measured one day and one hour before the surgery. All groups received routine education. In addition, the PE group received PE and the OP group received OP. Two questionnaires were used to collect the demographics and the clinical data; and Spielberg state anxiety questionnaire was used to measure the anxiety level. Data from descriptive statistics, chi-square, ANOVA, ANCOVA, Bonferroni, and Fisher exact test were analyzed in SPSS v20 software. Findings: The mean anxiety score before surgery was not significantly different in the three groups (P=0.955). However, after the intervention at 1 h before surgery, the mean anxiety level in the PE and OP group was lower than in the Cl group (P=0.000). However, the mean anxiety score between PE and OP groups showed no significant difference (P=0.051). Conclusion: Both PE and OP group reduced the anxiety naturally developed in a patient before surgery. Although the influence of the PE group was greater in reducing anxiety, the use of this technique in clinical practices required further studies.

To compare carprofen to butorphanol, with regard to postsurgical analgesic effects, duration of analgesia, and adverse side effects. Blinded, randomized clinical study. Seventy-one cats, 0.5-5 years of age, weighing 3.24 +/- 0.61 kg, undergoing ovariohysterectomy (OHE). Cats were premedicated with subcutaneous atropine (0.04 mg kg(-1)), acepromazine (0.02 mg kg(-1)), and ketamine (5 mg kg(-1)). Anesthesia was induced with ketamine (5 mg kg(-1)) and diazepam (0.25 mg kg(-1)) given intravenously, and maintained with isoflurane. There were three treatment groups: group C (4 mg kg(-1) carprofen SC at induction), group B (0.4 mg kg(-1) butorphanol SC at end of surgery), and group S (0.08 mL kg(-1) of sterile saline SC at induction and end of surgery). Behavioral data were collected using a composite pain scale (CPS), prior to surgery (baseline) and 1, 2, 3, 4, 8, 12, 16, 20, and 24 hours post-surgery. Interaction scores were analyzed separately. Cats with CPS scores >12 received rescue analgesia (meperidine, 4 mg kg(-1), intramuscular). Sixty cats completed the study. The CPS scores did not differ significantly between groups C and B at any time period. CPS scores for groups B and C were significantly increased for 12 hours post-surgery, and in group S for 20 hours. Both group C and B CPS scores were significantly lower than group S in this 20-hour postoperative period, except at 4 hours (B and C) and at 3 and 8 hours (B alone). Interaction scores for group C returned to preoperative baseline 4 hours after surgery, while both groups B and S remained increased for at least 24 hours post-surgery. Nine cats required meperidine. In this study, carprofen provided better postsurgical analgesia than butorphanol. Clinical relevance Neither drug completely abolished pain, however preoperative carprofen provided better pain control compared with postoperative butorphanol in the 24-hour period following OHE surgery in cats.

We report a single-center, prospective, randomized study for pedicle screw insertion in opened and percutaneous spine surgeries, using a computer-assisted surgery (CAS) technique with three-dimensional (3D) intra-operative images intensifier (without planification on pre-operative CT scan) vs conventional surgical procedure. We included 143 patients: Group C (conventional, 72 patients) and Group N (3D Fluoronavigation, 71 patients). We measured the pedicle screw running time, and surgeon's radiation exposure. All pedicle runs were assessed according to Heary by two independent radiologists on a post-operative CT scan. 3D Fluoronavigation appeared less accurate in percutaneous procedures (24 % of misplaced pedicle screws vs 5 % in Group C) (p = 0.007), but more accurate in opened surgeries (5 % of misplaced pedicle screws vs 17 % in Group C) (p = 0.025). For one vertebra, the average surgical running time reached 8 min in Group C vs 21 min in Group N for percutaneous surgeries (p = 3.42 × 10(-9)), 7.33 min in Group C vs 16.33 min in Group N (p = 2.88 × 10(-7)) for opened surgeries. The 3D navigation device delivered less radiation in percutaneous procedures [0.6 vs 1.62 mSv in Group C (p = 2.45 × 10(-9))]. For opened surgeries, it was twice higher in Group N with 0.21 vs 0.1 mSv in Group C (p = 0.022). The rate of misplaced pedicle screws with conventional techniques was nearly the same as most papers and a little bit higher with CAS. Surgical running time and radiation exposure were consistent with many studies. Our work hypothesis is partially confirmed, depending on the type of surgery (opened or closed procedure).

To investigate the association between surgical variables and the risk of revision surgery after ACL reconstruction in the Swedish National Knee Ligament Register. This cohort study was based on data from the Swedish National Knee Ligament Register. Patients who underwent primary single-bundle ACL reconstruction with hamstring tendon were included. Follow-up started with primary ACL reconstruction and ended with ACL revision surgery or on 31 December, 2014, whichever occurred first. Details on surgical technique were collected using an online questionnaire. All group comparisons were made in relation to an "anatomic" reference group, comprised of essential AARSC items, defined as utilization of accessory medial portal drilling, anatomic tunnel placement, visualization of insertion sites and pertinent landmarks. Study end-point was revision surgery. A total of 108 surgeons (61.7%) replied to the questionnaire. A total of 17,682 patients were included [n = 10,013 males (56.6%) and 7669 females (43.4%)]. The overall revision rate was 3.1%. Older age as well as cartilage injury evident at index surgery was associated with a decreased risk of revision surgery. The group using transtibial drilling and non-anatomic bone tunnel placement was associated with a lower risk of revision surgery [HR 0.694 (95% CI 0.490-0.984); P = 0.041] compared with the anatomic reference group. The anatomic reference group showed no difference in risk of revision surgery compared with the transtibial drilling groups with partial anatomic [HR 0.759 (95% CI 0.548-1.051), n.s.] and anatomic tunnel placement [HR 0.944 (95% CI 0.718-1.241), n.s.]. The anatomic reference group showed a decreased risk of revision surgery compared with the transportal drilling group with anatomic placement [HR 1.310 (95% CI 1.047-1.640); P = 0.018]. Non-anatomic bone tunnel placement via transtibial drilling resulted in the lowest risk of revision surgery after ACL reconstruction. The risk of revision surgery increased when using transportal drilling. Performing anatomic ACL reconstruction utilizing eight selected essential items from the AARSC lowered the risk of revision surgery associated with transportal drilling and anatomic bone tunnel placement. Detailed knowledge of surgical technique using the AARSC predicts the risk of ACL revision surgery. III.

The aim of this study is to assess the difficulty of intracorporeal suturing in single-port surgery, using experimental suturing model in dry box. Subjects were divided for three groups: seven experienced laparoscopic surgeons, seven surgical residents, and seven interns. An experimental suturing model is developed, and working angle was set from 0° to 90°. The completion rate in 0° was significantly lower than that in the other angles. Completion rate of group A was higher than that of the other groups. Precision of task in group A was significantly higher than that of group B and group C in 0° and 60°. Stress score in 0° were significantly higher than that in the other angles. Our study demonstrated that intracorporeal suturing in single-port surgery seems to be more difficult than conventional laparoscopic surgery. Our data should be taken the institution under consideration for introduction of single-port surgery.

Fibrous hyperplasia is treated by surgical incision using a scalpel, together with removal of the source of chronic trauma. However, scalpel techniques do not provide the haemostasis that is necessary when dealing with highly vascular tissues. Diode laser surgery can be used in the management of oral tissues due to its high absorption by water and haemoglobin, and has provided good results in both periodontal surgery and oral lesions. The aim of the present study was to compare the effects of diode laser surgery to those of the conventional technique in patients with fibrous hyperplasia. A randomized clinical trial was performed in which surgical and postoperative evaluations were analyzed. On comparison of the laser-treated (study group) patients to those treated with a scalpel (control group), significant differences were observed in the duration of surgery and the use of analgesic medications. Over a 3-week period, clinical healing of the postoperative wound was significantly faster in the control group as compared to the study group. In conclusion, diode laser surgery proved to be more effective and less invasive when compared to scalpel surgery in the management of fibrous hyperplasia. However, wound healing proved to be faster when using scalpel surgery. Copyright © 2015 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd. All rights reserved.

Devendra, Jaya; Singh, Sneha

2015-10-01

Cataract surgery is one of the most frequently performed intra-ocular surgeries, of these manual Small Incision Cataract Surgery (SICS) is a time tested technique of cataract removal. Any corneal incisional surgery, including cataract surgery, can induce dry eye postoperatively. Various factors have been implicated, of which oneis the inflammation induced by the surgery. Lactoferrin, a glycoprotein present in tears is said to have anti-inflammatory effects, and promotes cell growth. It has been used orally in patients of immune mediated dry eye to alleviate symptoms. This study was aimed to evaluate the dry eyes induced by manual Small Incision Cataract Surgery, and the effect if any, of oral lactoferrin on the dry eyes. A single centre, prospective randomised controlled trial with a concurrent parallel design. The study was carried out on patients presenting in the OPD of Rohilkhand Medical College hospital for cataract surgery. Sixty four patients of cataract surgery were included in the study. Patients with pre-existing dry eyes, ocular disease or systemic disease predisposing to dry eyes were excluded from the study. The selected patients were assigned into two groups by simple randomisation-Control Group A-32 patients that did not receive oral lactoferrin postoperatively. Group B-32 patients that received oral lactoferrin 350 gm postoperatively from day 1 after SICS. All patients were operated for cataract and their pre and postoperative (on days 7, 14, 30 and 60) dry eye status was assessed using the mean tear film break-up time (tBUT) and Schirmer test 1 (ST 1) as the evaluating parameters. Subjective evaluation of dry eye was done using Ocular Surface Disease Index (OSDI) scoring. Data was analysed for 58 patients, as 6 did not complete the follow up. Unpaired t-test was used to calculate the p-values. There was a statistically significant difference between the tBUT values of the Control and Lactoferrin group from day 14 onwards. The tBUT of control group on day 60 was 7.86 (±0.86) seconds as compared to 13.9(± 0.99) seconds in the lactoferrin group. The Schirmer test 1 values also showed a statistically significant difference between the two groups- 15.86 (± 5.83) seconds in the control group versus 30.9 (±1.66) in the lactoferrin group on day 60. OSDI score showed 42.8% patients complaining of at least mild dry eye symptoms in the control group, as compared to 26.6% patients in the lactoferrin group on day 60. Small Incision Cataract Surgery induces dry eye postoperatively. Oral lactoferrin given postoperatively improves tear film status and dry eye after cataract surgery.

Patient anxiety about nail surgery relates mainly to pain associated with needle puncture, anesthetic flow during the procedure, and postoperative care, as well as possible past traumatic experience. The aims of this study were to compare anxiety levels among patients undergoing nail surgery and skin punch biopsy and to assess the effects of demographic characteristics on anxiety. Forty-eight consecutive patients who were referred to a dermatological surgery unit for nail surgery intervention (group 1) and 50 age- and sex-matched patients referred to the same unit for skin punch biopsy (group 2) were enrolled in the study. Patients' anxiety levels were measured using Spielberger's State-Trait Anxiety Inventory. There was no significant difference in median anxiety level between group 1 (42.00; interquartile range, 6.50) and group 2 (41.00; interquartile range, 8.25) (P = .517). The demographic factors of patient sex, educational status, and prior surgery showed no significant effects on anxiety levels. Nail surgery does not seem to cause significantly greater anxiety than skin punch biopsy. © The Author(s) 2015.

To evaluate the effects of orthodontic camouflage treatment (OCT), one-jaw surgery, and two-jaw surgery on the correction of lip line cant (LLC) and to examine factors affecting the correction of LLC in Class III craniofacial asymmetry patients. A sample of 30 Class III craniofacial asymmetry patients was divided into OCT (n = 10), one-jaw surgery (n = 10), and two-jaw surgery (n = 10) groups such that the pretreatment LLC was similar in each group. Pretreatment and posttreatment cone-beam computed tomography scans were used to measure dental and skeletal parameters and LLC. Pretreatment and posttreatment measurements were compared within groups and between groups. Pearson's correlation tests and multiple regression analyses were performed to investigate factors affecting the amount and rate of LLC correction. The average LLC correction was 1.00° in the one-jaw surgery group, and in the two-jaw surgery group, it was 1.71°. In the OCT group it was -0.04°, which differed statistically significantly from the LLC correction in the other two groups. The amount and rate of LLC correction could be explained by settling of skeletal discrepancies or LLC at pretreatment with goodness of fit percentages of approximately 82% and 41%, respectively. Orthognathic surgery resulted in significant correction of LLC in Class III craniofacial asymmetry patients, while OCT did not.

Preoperative fasting is an established procedure to be practiced for patients before surgery, but optimal preoperative fasting time still remains controversial. The aim of this study was to investigate the effect of "shortened preoperative fasting time" on the change in the amount of total body water (TBW) in elective surgical patients. TBW was measured by multi-frequency impedance method. The patients, who were scheduled to undergo surgery for stomach cancer, were divided into two groups of 15 patients each. Before surgery, patients in the control group were managed with conventional preoperative fasting time, while patients in the "enhanced recovery after surgery (ERAS)" group were managed with "shortened preoperative fasting time" and "reduced laxative medication." TBW was measured on the day before surgery and the day of surgery before entering the operating room. Defecation times and anesthesia-related vomiting and aspiration were monitored. TBW values on the day of surgery showed changes in both groups as compared with those on the day before surgery, but the rate of change was smaller in the ERAS group than in the control group (2.4±6.8% [12 patients] vs. -10.6±4.6% [14 patients], p<0.001). Defecation times were less in the ERAS group. Vomiting and aspiration were not observed in either group. The results suggest that preoperative management with "shorted preoperative fasting time" and "reduced administration of laxatives" is effective in the maintenance of TBW in elective surgical patients.

Hypotensive anesthesia is crucial during arthroscopic shoulder surgery to reduce bleeding and allow for clear visibility. The aim of this study was to compare the clinical efficacy of continuous infusion of remifentanil, nicardipine, and remifentanil plus nicardipine to control hypotensive anesthesia in arthroscopic shoulder surgery. For this study, we enrolled 45 consecutive patients who were scheduled to have arthroscopic rotator cuff repair surgery and randomly allocated them into remifentanil (group R, n = 15), nicardipine (group N, n = 15), and remifentanil plus nicardipine (group RN, n = 15) groups. During the surgeries, these drugs were administered with continuous infusion. We analyzed the mean arterial pressure (MAP) and heart rate during surgery, stay time in the recovery room, visual analogue scale (VAS) scores, use of antiemetics in the recovery room, and postoperative blood urea nitrogen and creatinine changes. The VAS score in the recovery room was higher for group R (mean 5.6, SD 1.4) than for groups N (mean 3.9, SD 0.9) and RN (mean 4.0, SD 1.1; p = 0.000). There were no statistical differences regarding other clinical variables among the three groups (all p > 0.05) except for MAP at 120 min of surgery between groups N and RN (N: 84.67 (SD 10.7) mmHg, RN: 65.4 (SD 9.2) mmHg, p = 0.027). The continuous infusion of remifentanil plus nicardipine appeared to be advantageous for maintaining hypotensive anesthesia until 120 min of arthroscopic shoulder surgery without rebound pain in a postanesthesia care unit.

In this prospective, randomized, double-blind study, we evaluated and compared the incidence of postoperative nausea and vomiting (PONV) after paediatric strabismus surgery with two different anaesthetic methods, sevoflurane or remifentanil-sevoflurane. In total, 78 paediatric patients (aged 6-11 yr) undergoing strabismus surgery were enrolled and randomly assigned to two groups, sevoflurane (Group S) and remifentanil-sevoflurane (Group R). Anaesthesia was maintained with 2-3% sevoflurane in Group S (n=39) or with a continuous infusion of remifentanil combined with 1% sevoflurane in Group R (n=39), both using 50% N(2)O/O(2). Arterial pressure and heart rate before induction, after tracheal intubation, after skin incision, and at the end of surgery were recorded. The incidence of PONV in the post-anaesthesia care unit, the day surgery care unit, and at home 24 h after surgery was recorded. Arterial pressure and heart rate were stable throughout the surgery, but were significantly lower in Group R than in Group S after tracheal intubation and skin incision. The incidence of PONV and postoperative vomiting was 17.9%/17.9% and 12.8%/10.2% (Group S/Group R) at the respective time points; values were comparable between the groups. The incidence of PONV after paediatric strabismus surgery under sevoflurane anaesthesia was relatively low, and combining remifentanil with sevoflurane did not further increase the incidence.

The aim of this study was the comparision of postoperative outcomes in impacted mandibular third molars that were treated using either platelet-rich fibrin (PRF), a combination of PRF and piezosurgery, or conventional rotatory osteotomy. The study included 20 patients; 40 extractions of impacted mandibular third molars were performed. Patients were divided into two main groups. In group A (n = 20), traditional surgery was performed on one side (Group 1, n = 10); traditional surgery was performed, and PRF was administered to the extracted socket on the other side of same patient (Group 2, n = 10). In group B (n = 20), on one side, piezosurgery was used for osteotomy, and PRF was administered (Group 3, n = 10); on the other side of same patient, traditional surgery was performed (Group 4, n = 10). Parameters assessed at baseline for each patient included pain, the number of analgesics taken, trismus, and cheek swelling. These variables were also assessed on postoperative days 1, 2, 3, and 7. Statistical analysis revealed a significant reduction in postoperative pain (sum of 1(st), 2(nd), 3(rd) and 7(th) days) and trismus (on postoperative day 1) in group 2 (traditional surgery + PRF group), and in postoperative pain, the number of analgesics taken (sum of 1(st), 2(nd),3(rd) and 7(th) days) and trismus (on postoperative day 1) in group 3 (piezosurgery + PRF group) compared to groups 1 and 4 (traditional surgery groups), (p ≤ 0.05). However, swelling on postoperative days 1, 3, and 7 did not differ among the groups (p > 0.05). Only difference was on second day between groups 1-4 and 2-4 (p ≤ 0.05). The results of our study have shown that the use of PRF with traditional surgery and PRF combined with piezosurgery significantly reduced pain during the postoperative period. In addition, PRF in combination with piezosurgery significantly decreased the number of analgesics taken. Both operations also significantly decreased trismus 24 h after the surgery. As a result of this study, PRF and combination use of PRF and piezosurgery have positive effects in reducing postoperative outcomes after impacted third molar surgery.

The aim of this study was to assess the use of mechanical bowel preparation (MBP) and antimicrobial prophylaxis in elective colorectal surgery regarding still existing controversies. A prospective study of 85 patients undergoing elective colon and rectal surgery during 2 years period was performed, divided in two groups. Group A (N = 46) with patients who underwent mechanical bowel preparation, and group B (N = 39) patients without mechanical bowel preparation. We analysed: gender, age, preoperative difficulties, diagnostic colonoscopy, tumor localization, operation performed, pathohystological findings, Dukes classification, number of lymphonodes inspected, liver metastasis, other organ infiltrations, mean time of surgery, length of hospital stay, postoperative complications and mortality. Demographic characteristics, pathohystological findings, the site of malignancy, and type of surgical procedure did not significantly differentiate the two groups. The only significance revealed in mean time of surgery (138/178 minutes) in favor of patients with MBP (p = 0.017). Mechanical bowel preparation (MBP) for elective colorectal surgery is not advantageous. It does not influence radicalism of the procedure, does not decrease neither postoperative complications, nor hospital mortality.

To study the effect of aprotinin (Trasylol) administration on bleeding after surgery and on the need for blood transfusion in patients undergoing cardiopulmonary bypass with extracorporeal circulation (ECC). One hundred ten patients were studied prospectively, divided into two groups. In the aprotinin group (n = 80), the ECC pump was primed with 140 mg of aprotinin and followed with continuous intravenous perfusion at 70 mg/h from the start of ECC until the patient left the operating theater. The control group (n = 30) served as reference. The parameters compared were the hematocrit, number of platelets, prothrombin time and activated coagulation time, as well as drainage of blood through thoracic tubes at 3 and 24 h after surgery and the amount of blood transfused both during and after the procedure. Blood loss was significantly lower in the aprotinin group as compared with the control group, both at 3 h (227 +/- 193 vs 380 +/- 169 ml; p < 0.05) and at 24 h (422 +/- 322 ml vs 736 +/- 342 ml; p < 0.05) after surgery. There was also a significant decrease in blood requirements in the aprotinin group (550 +/- 450 ml vs 872 +/- 747 ml; p < 0.05). There were no differences between the two groups for the other parameters studied. Administration of aprotinin at low doses during surgery in patients undergoing cardiac surgery with ECC significantly reduces postoperative bleeding and the amount of blood transfused.

Recent studies have indicated that bone shows auto-fluorescence under an appropriate fluorescence lamp. The aim of this preliminary study was to compare the success rates of the established tetracycline fluorescence-guided bone surgery with auto-fluorescence-guided bone surgery in the treatment of medication-related osteonecrosis of the jaw (MRONJ). Forty patients suffering from MRONJ were referred for surgical treatment and were divided randomly into two groups: auto-fluorescence (n=20) or tetracycline fluorescence (n=20) guided bone surgery. The primary endpoint was treatment success, defined as the absence of exposed bone at 8 weeks after surgery. Secondary outcomes assessed were mucosal integrity, signs of infection, pain, and loss of sensitivity; these were evaluated descriptively at 10 days, 8 weeks, 6 months, and 1 year after surgery. At 8 weeks postoperative, 18/20 patients (90%) in the auto-fluorescence group and 17/20 patients (85%) in the tetracycline fluorescence group showed mucosal integrity (P>0.05). At the last follow-up, 94% in the auto-fluorescence group and 89% in the tetracycline fluorescence group presented complete mucosal coverage with no exposed bone, infection, or pain (P>0.05). There was no significant difference between the two techniques for any of the secondary outcomes (P>0.05). The results of this preliminary study show that auto-fluorescence-guided bone surgery has comparable success rates to the established tetracycline fluorescence-guided bone surgery.

Objective To compare the operative outcomes, postoperative pain, and subsequent convalescence after laparoendoscopic single-site surgery (LESS) or conventional laparoscopic surgery for adnexal preservation. Study design From December 2009 to September 2010, 63 patients underwent LESS (n = 33) or a conventional laparoscopic surgery (n = 30) for cyst enucleation. The overall operative outcomes including postoperative pain measurement using the visual analog scale (VAS) were evaluated (time points 6, 24, and 24 hours). The convalescence data included data obtained from questionnaires on the need for analgesics and on patient-reported time to recovery end points. Results The preoperative characteristics did not significantly differ between the two groups. The postoperative hemoglobin drop was higher in the LESS group than in the conventional laparoscopic surgery group (P = 0.048). Postoperative pain at each VAS time point, oral analgesic requirement, intramuscular analgesic requirement, and the number of days until return to work were similar in both groups. Conclusion In adnexa-preserving surgery performed in reproductive-age women, the operative outcomes, including satisfaction of the patients and convalescence after surgery, are comparable for LESS and conventional laparoscopy. LESS may be a feasible and a promising alternative method for scarless abdominal surgery in the treatment of young women with adnexal cysts PMID:22448110

Previous studies have demonstrated that early surgery in Crohn disease (CD) can result in a better clinical course than late surgery. The aim of this study was to compare the clinical course of CD following bowel resection performed at the time of diagnosis (early surgery) and during the course of the disease (late surgery).We reviewed medical records from a hospital-based cohort database that includes Korean CD patients diagnosed before 2009. Patients who underwent bowel resection were included. Age, sex, disease phenotype, time of surgery, medication history including use of corticosteroids, immunomodulators, and biologics, and further surgical history were assessed.In all, 243 CD patients who had undergone bowel resection were included, and 120 patients underwent surgery at the time of diagnosis, while 123 underwent surgery after diagnosis (median 105 months, range 2-277). The use of biologics was significantly higher in the late surgery group than in the early surgery group (P = .020). The use of immunomodulators and reoperation rates did not differ between the groups. Early surgery was associated with less use of biologics (Kaplan-Meier curve analysis P = .015). Multivariate analysis indicated that early surgery and old age at surgery were independent variables associated with less use of biologics.CD patients who underwent bowel resection at the time of diagnosis have a more favorable disease course, represented by less use of biologics. Early surgery might be a treatment option in a subset of CD patients.

Background Studies of the impact of pre-surgery weight loss and lifestyle preparation on outcomes following bariatric surgery are needed. Objective To evaluate whether a pre-surgery behavioral lifestyle intervention improves weight loss through 24-months post-surgery. Setting Bariatric Center of Excellence at a large, urban medical center. Methods Candidates for bariatric surgery were randomized to a 6-month behavioral lifestyle intervention or to 6 months of usual pre-surgical care. The lifestyle intervention consisted of 8 weekly face-to-face sessions followed by 16 weeks of face-to-face and telephone sessions prior to surgery; the intervention also included 3 monthly telephone contacts after surgery. Assessments were conducted at 6-, 12- and 24-months post-surgery. Results Participants who underwent surgery (n = 143) were 90.2% female and 86.7% White. Average age was 44.9 years, and average BMI was 47.5 kg/m2 at study enrollment. At follow-up, 131 (91.6%), 126 (88.1%), 117 (81.8%) patients participated in the 6-, 12- and 24 month assessments, respectively. Percent weight loss from study enrollment to 6- and 12-months post-surgery was comparable for both groups, but at 24-months post-surgery, the lifestyle group had significantly smaller percent weight loss than the usual care group (26.5% vs. 29.5%, respectively, p = 0.02). Conclusions Pre-surgery lifestyle intervention did not improve weight loss at 24 months post-surgery. Findings raise questions about the utility and timing of adjunctive lifestyle interventions for bariatric surgery patients. PMID:26410538

To compare the clinical outcome of pterygium surgery combining intraoperative mitomycin C (MMC) with a free conjunctival autograft, with three other methods of pterygium surgery, including intraoperative MMC alone, conjunctival autograft alone, and bare sclera without adjunctive treatment. Interventional, randomized and in part nonrandomized, prospective, comparative study. setting: A university medical center department of ophthalmology. One hundred and twenty patients underwent pterygium excision surgery. These patients were divided into four treatment groups. In group 1 (30 patients), MMC, 0.2 mg/ml, was applied for three minutes. In group 2 (30 patients), conjunctival autografting was performed. Group 3 (30 patients) received sodium chloride 0.9% only, and group 4 (30 patients) underwent conjunctival autografting combined with one minute application of MMC, 0.2 mg/ml. Recurrence rates and complications. Pterygium recurred in two patients (6.6%) in group 1, in four patients (13.3%) in group 2, in 14 patients (46.6%) in group 3, and in none of the patients in group 4. chi(2) analysis revealed a significantly lower recurrence rate in group 4 compared with group 2 (P = .038) and with group 3 (P < .0001). Epithelialization of the wounds was complete within 14 days of surgery. No complications were demonstrated in any of the study groups except for one case of minor melting of the flap in group 4. This study indicates that pterygium excision with a free conjunctival autograft combined with intraoperative low-dose MMC is a safe and effective technique in pterygium surgery.

To assess the impact of a short hypnotic session on postoperative anxiety and pain in major orthopaedic surgery. Despite specific information given before a scheduled paediatric surgery, perioperative anxiety can become important. Randomised Clinical Study. The study is an open single-centre randomised clinical study comparing a "control" group versus a "hypnosis" group receiving a short hypnosis pre-induction session as additional experimental analgesic procedure. The primary endpoint was the postoperative anxiety, blindly assessed using a visual analogue scale. The study involved 120 children (age 10-18 years). The results showed no difference between control group versus hypnosis group. Twenty-four hours after surgery (Day+1), the patient's anxiety score was not different between control and hypnosis groups (median [Q1-Q3]: 1 [0; 3] vs. 0 [0; 3], respectively, p = .17). Each group experienced a significant decrease in anxiety level between the day before surgery (Day-1) and the day after surgery (Day+1) (median ([Q1-Q3]) difference of the anxiety score: 2 [4; 0] and 2 [4; 0], respectively, p < .0001 in each group). The postoperative pain scores were low and not different between groups (median [Q1-Q3]: 2 [0; 3] in control group vs. 3 [1; 3] in hypnosis group, p = .57). This randomised study on a short hypnosis session performed in the operating room prior to a major surgery showed no difference in postoperative anxiety and pain levels. The decrease in anxiety and pain levels may be due to the addition of nurse pre-operative interviews and optimisation in communication in the operating room. As postoperative anxiety level was low in both control and hypnosis groups, nurse pre-operative interviews and nurse training in hypnosis may contribute to the optimisation of global management and decrease the postoperative anxiety level. © 2017 John Wiley & Sons Ltd.

Effect of a single acupuncture treatment on surgical wound healing in dogs: a randomized, single blinded, controlled pilot study

PubMed Central

2010-01-01

Background The aim of the study was to investigate the effect of acupuncture on wound healing after soft tissue or orthopaedic surgery in dogs. Methods 29 dogs were submitted to soft tissue and/or orthopaedic surgeries. Five dogs had two surgical wounds each, so there were totally 34 wounds in the study. All owners received instructions for post operative care as well as antibiotic and pain treatment. The dogs were randomly assigned to treatment or control groups. Treated dogs received one dry needle acupuncture treatment right after surgery and the control group received no such treatment. A veterinary surgeon that was blinded to the treatment, evaluated the wounds at three and seven days after surgery in regard to oedema (scale 0-3), scabs (yes/no), exudate (yes/no), hematoma (yes/no), dermatitis (yes/no), and aspect of the wound (dry/humid). Results There was no significant difference between the treatment and control groups in the variables evaluated three and seven days after surgery. However, oedema reduced significantly in the group treated with acupuncture at seven days compared to three days after surgery, possibly due the fact that there was more oedema in the treatment group at day three (although this difference was nor significant between groups). Conclusions The use of a single acupuncture treatment right after surgery in dogs did not appear to have any beneficial effects in surgical wound healing. PMID:20950467

This study aimed to evaluate the effects of ultrasound-guided rectus sheath block in gynaecological surgery with Pfannenstiel incision. After the approval of the ethics committee and the patients' consent, 75 ASA I-II patients who were aged between 20 and 70 years and scheduled for a gynaecological surgery with Pfannenstiel incision were included in this study. After induction of general anaesthesia, patients were randomly divided into three groups. In Group UR patients (n=25), ultrasound-guided rectus sheath block with 0.25% levobupivacaine (0.2 mL kg(-1)) was performed. In Group SR patients (n=25), surgical rectus sheath block with 0.25% levobupivacaine (0.2 mL kg(-1)) was applied. In Group T (n=25) patients, tramadol (2 mg kg(-1)) was intravenously administered 30 min before the end of surgery. Patient-controlled analgesia device was established for postoperative pain relief in all groups. Haemodynamic data and inspired sevoflurane concentration were recorded during the operation. Pain scores, total tramadol consumption, supplemental analgesic requirement and side effects were postoperatively evaluated. Demographic characteristics, duration of surgery and haemodynamic parameters were similar between the groups. Inspired sevoflurane concentration (%) and VAS scores were significantly lower in Group UR than those in Groups SR and T. Total tramadol consumption was significantly lower in Groups UR and SR than that in Group T. There was no significant difference in the incidence of side effects. This study demonstrates that ultrasound-guided rectus sheath block helps to provide the effective analgesia without any side effects compared with surgical rectus sheath block and intravenous tramadol for gynaecological surgery with Pfannenstiel incision.

Cataract is a leading cause of vision impairment worldwide, and surgery is the only available treatment. The process that initiates lens opacification is dependent on the oxidative stress experienced by the lens components. A healthy overall dietary pattern, with the potential to reduce oxidative stress, has been suggested as a means to decrease the risk of developing cataract. We aimed to investigate the hypothesis that an intervention with a Mediterranean diet (MedDiet) rather than a low-fat diet could decrease the incidence of cataract surgery in elderly subjects. We included 5802 men and women (age range: 55-80 years) from the Prevención con Dieta Mediterránea study (multicenter, parallel-group, randomized controlled clinical trial) who had not undergone cataract surgery. They were randomly assigned to one of three intervention groups: (1) a MedDiet enriched with extra-virgin olive oil (EVOO) ( n = 1998); (2) a MedDiet enriched with nuts ( n = 1914), and a control group recommended to follow a low-fat diet ( n = 1890). The incidence of cataract surgery was recorded yearly during follow-up clinical evaluations. Primary analyses were performed on an intention-to-treat basis. Cox regression analyses were used to assess the relationship between the nutritional intervention and the incidence of cataract surgery. During a follow-up period of 7.0 years (mean follow-up period: 5.7 years; median: 5.9 years), 559 subjects underwent cataract surgery. Two hundred and six participants from the MedDiet + EVOO group, 174 from the MedDiet + Nuts group, and 179 from the control group underwent cataract surgery. We did not observe a reduction in the incidence of cataract surgery in the MedDiet groups compared to the control group. The multivariable adjusted hazard ratios were 1.03 (95% confidence interval [CI]: 0.84-1.26, p = 0.79) for the control group versus the MedDiet + EVOO group and 1.06 (95% CI: 0.86-1.31, p = 0.58) for the control group versus the MedDiet + Nuts group. To our knowledge, this is the first large randomized trial assessing the role of a MedDiet on the incidence of cataract surgery. Our results showed that the incidence of cataract surgery was similar in the MedDiet with EVOO, MedDiet with nuts, and low-fat diet groups. Further studies are necessary to investigate whether a MedDiet could have a preventive role in cataract surgery.

The aim of this study was to investigate the effects of oral carbohydrate solution (CHO) on perioperative discomfort, biochemistry, hemodynamics, and patient satisfaction in elective surgery patients under general anesthesia. Sixty cases in ASA I-II group who were planned to have operation under general anesthesia were included in the study. The cases were randomly divided into two groups having 30 subjects in each. The patients in the study group were given CHO in the evening prior to the surgery and 2-3 hr before the anesthesia while routine fasting was applied in the control group. In the study group; 2-3 hr before the surgery; malaise, thirst, hunger, and weakness; just before the surgery malaise, thirst, hunger, and fatigue; 2 hr after the operation thirst, hunger, weakness, and concentration difficulty; 24 hr after the operation malaise and weakness were found significantly lower. Fasting blood glucose (FBG) level was found to be higher in the control group at the 90th min of the operation. Gastric volumes were higher in the control group; gastric pH values were found significantly higher in the study group. The level of anxiety and depression risk rate were found lower in the study group. In conclusion, preoperative CHO reduces perioperative discomfort and improves perioperative well being when compared to overnight fasting.

Laparoscopic surgery in Korea increased rapidly because of the early detection of gastric cancer by the development of diagnostic tools and nationwide screening. The Korean Laparoscopic Gastrointestinal Surgery Study Group (KLASS group) played a leading role in various projects related with minimally invasive surgery. The justification of minimally invasive procedures including robotic surgery, sentinel-node biopsy, or single-port surgery/Natural Orifice Transluminal Endoscopic Surgery (NOTES) must be predetermined by the clinical trial before a wide application, and the medical industry as well as surgeons should have great responsibility.

Obstetric haemorrhage accounts for 20-25% of maternal mortality and morbidity. Anti-fibrinolytics are being widely used in field of surgery. It is also used to reduce heavy menstrual blood loss. To analyse the effectiveness of Tranexamic Acid (TXA) in reducing blood loss during elective caesarean section. This interventional, randomized, parallel group study was done in the Department of Obstetrics and Gynaecolgy, PSG IMSR, Coimbatore, from June 2014 to May 2015. It was conducted on 120 women undergoing caesarean section. They were allocated to either Study or Control group by computer generated random number tables. TXA was given prior to surgery in study group in addition to the routine care {10 units of oxytocin added to the intravenous drip soon after baby delivery} whereas, the control group had routine care alone. Blood loss was measured in both groups by gravimetric method. Haemoglobin before and after surgery was estimated and the percentage of difference was compared. Primary outcome variables were volume of blood loss and percentage fall in haemoglobin before and after surgery. Secondary outcomes were duration of surgery, proportion of subjects with >500ml of blood loss, need for additional uterotonics and side effects. Unpaired t-test and Chi-square test were used to compare the outcome variables. There was significant reduction in blood loss calculated from placental delivery till end of surgery: 347.17ml in study group versus 517.72ml in control group (p<0.001). Another parameter studied was the percentage of fall in haemoglobin before and after surgery and the number of subjects who had more than 10% fall in haemoglobin. 9.3% of subjects in study group and 39% of subjects in control group had more than 10% fall in haemoglobin (p<0.01). There were no immediate post-operative complications to the mother and neonate. TXA significantly reduced the amount of blood loss during Lower Segment Caesarean Section (LSCS). Use of TXA was not associated with adverse effects. Thus, TXA can be used safely and effectively in subjects undergoing LSCS.

Objective: To evaluate the effectiveness of prophylactic administration of nepafenac 0.1% in maintaining mydriasis and in preventing postoperative macular edema following cataract surgery. Methods: This was a prospective, randomized, single-masked comparative study in 60 patients undergoing phacoemulsification cataract surgery. Patients were randomized to either the nepafenac or the control group. Nepafenac was administered 3 times daily 1 day before surgery and continued for 6 weeks. The control group received tobramycin-dexamethasone treatment only. Trans-operative mydriasis was measured before surgery, after nuclear emulsification, following cortex aspiration, and at the conclusion of surgery. Macular optical coherence tomography determined central foveal thickness (FT) and total macular volume (TMV) before surgery and at 2 and 6 weeks after surgery. All patients received tobramycin-dexamethasone for 2 weeks after surgery. Results: The difference in mean pupil size, at the end of surgery, between the control group (6.84 ± 0.93 mm) and the nepafenac group (7.91 ± 0.74 mm) was statistically significant (p < 0.001). There were no significant differences in FT values between the two groups at any time point; however, TMV at 2 and at 6 weeks was statistically significantly different (p < 0.001), with higher TMV in the control group. Conclusion: Prophylactic use of nepafenac was effective in reducing macular edema after cataract surgery and in maintaining trans-operative mydriasis. PMID:19668569

OBJECTIVE To analyze the incremental cost-utility ratio for the surgical treatment of hip fracture in older patients. METHODS This was a retrospective cohort study of a systematic sample of patients who underwent surgery for hip fracture at a central hospital of a macro-region in the state of Minas Gerais, Southeastern Brazil between January 1, 2009 and December 31, 2011. A decision tree creation was analyzed considering the direct medical costs. The study followed the healthcare provider’s perspective and had a one-year time horizon. Effectiveness was measured by the time elapsed between trauma and surgery after dividing the patients into early and late surgery groups. The utility was obtained in a cross-sectional and indirect manner using the EuroQOL 5 Dimensions generic questionnaire transformed into cardinal numbers using the national regulations established by the Center for the Development and Regional Planning of the State of Minas Gerais. The sample included 110 patients, 27 of whom were allocated in the early surgery group and 83 in the late surgery group. The groups were stratified by age, gender, type of fracture, type of surgery, and anesthetic risk. RESULTS The direct medical cost presented a statistically significant increase among patients in the late surgery group (p < 0.005), mainly because of ward costs (p < 0.001). In-hospital mortality was higher in the late surgery group (7.4% versus 16.9%). The decision tree demonstrated the dominance of the early surgery strategy over the late surgery strategy: R$9,854.34 (USD4,387.17) versus R$26,754.56 (USD11,911.03) per quality-adjusted life year. The sensitivity test with extreme values proved the robustness of the results. CONCLUSIONS After controlling for confounding variables, the strategy of early surgery for hip fracture in the older adults was proven to be dominant, because it presented a lower cost and better results than late surgery.

Recurrent respiratory papillomatosis (RRP) is a benign epithelial tumor that exhibits a high frequency of recurrence. This study assesses the vocal function after laser treatment for RRP, particularly in relation to the frequency of surgery. Retrospective study. Thirty RRP patients who underwent laser surgery that controlled the tumor were included. Preoperative and postoperative Grade, Roughness, Breathiness, Asthenia, and Strain Scale, videostroboscopic findings, aerodynamic and acoustic parameters, and self-assessment questionnaires were measured and compared with an age- and sex-matched control group. Subsequently, to evaluate the association between postoperative voice quality and the number of surgeries, the patients were divided into three groups (group 1: single surgery, group 2: 2-5 surgeries, group3: >6 surgeries), and comparative multidimensional vocal assessments were performed. The mean number of surgeries was 3.4 (range, 1-8). Although all patients exhibited poorer vocal function than the control group preoperatively, they showed improvement in postoperative subjective and objective parameters. However, four patients who underwent one surgery with relatively aggressive ablation exhibited vocal cord scarring and deteriorated objective parameters. All remaining patients showed voice quality that was on par with the control group. Subgroup analysis proved no association between post-therapeutic voice quality and the patient characteristics, including preoperative staging and the number of surgical treatments performed. RRP patients can achieve a close to normal voice with high satisfaction even after recurrent surgical treatment when ablation of a subepithelial lesion using sufficient laser energy is adequate. 3b Laryngoscope, 127:679-684, 2017. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

The issue of cost effectiveness of laparoscopic surgery remains uncertain and its impact on the ward nursing staff is unaddressed. This study investigated these issues using patients from a single centre admitted to a randomized controlled trial. All patients recruited into the Australasian Laparoscopic Colon Cancer Study (ALCCaS) from The Queen Elizabeth Hospital between January 1999 and March 2005 were included in this study. Data relating to hospital cost were collated from the Hospital Patient Costing System. Nursing interventions were calculated in minutes per patient, using the excelcare Software database. Data from 97 patients were analysed (laparoscopy, 53; open surgery, 44). The median number of hours of nursing input per patient was 80 (27.5-907) h in the open surgery group and 58.5 (15-684.5) h in the laparoscopy group. This difference was further increased after exclusion of patients converted from laparoscopy to open surgery. The median total cost of the procedure was AUS $9698/£ 5631 (AUS $3862-90,397) in the open surgery group and AUS $10,951/£ 6219 (AUS$2337-66,237) in the laparoscopy group. These data suggest that laparoscopic colorectal surgery is equivalent in price to open surgery and there may be added benefits in reduced nursing intensity. © 2011 The Authors.

The purposes of the study were to investigate and evaluate the differences detected by the patients between the traditional orthognathic approach and the surgery-first one in terms of level of satisfaction and quality of life. A total of 30 patients who underwent orthognathic surgery for correction of malocclusions were selected and included in this study. Fifteen patients were treated with the conventional orthognathic surgery approach, and 15 patients with the surgery-first approach. Variables were assessed through the Orthognathic Quality of Life Questionnaire and the Oral Health Impact Profile questionnaire and analyzed with 2-way repeated-measures analysis of variance. The results showed significant differences in terms of the Orthognathic Quality of Life Questionnaire (P <0.001) and the Oral Health Impact Profile (P <0.001) scores within groups between the first and last administrations of both questionnaires. Differences in the control group between first and second administrations were also significant. Questionnaire scores showed an immediate increase of quality of life after surgery in the surgery-first group and an initial worsening during orthodontic treatment in the traditional approach group followed by postoperative improvement. This study showed that the worsening of the facial profile during the traditional orthognathic surgery approach decompensation phase has a negative impact on the perception of patients' quality of life. Surgeons should consider the possibility of a surgery-first approach to prevent this occurrence. Copyright © 2017 American Association of Orthodontists. Published by Elsevier Inc.

Best practices for patient education in bariatric surgery (BS) remain undefined. The aims of this study were to evaluate the effect of an online lecture on nutrition knowledge, weight loss expectations, and anxiety among BS candidates and present a new tool to assess this knowledge before BS. An interventional non-randomized controlled trial on 200 BS candidates recruited while attending a pre-BS committee. The first 100 consecutive patients were assigned to the control group and the latter 100 consecutive patients to the intervention group and were instructed to watch an online lecture of 15-min 1-2 weeks prior to surgery. All participants completed a BS nutrition knowledge and the state-trait anxiety inventory (STAI) questionnaires at the pre-BS committee and once again at the pre-surgery clinic. Body mass index (BMI), comorbidities, surgery type, marital status, and number of dietitian sessions were obtained from medical records. Data for paired study questionnaires scores were available for 128 patients (n = 69 and n = 59 for the control and intervention groups, respectively), with a mean age and BMI of 40.3 ± 11.4 years and 41.3 ± 4.9 kg/m 2 , respectively. The BS nutrition knowledge and the state anxiety scores increased for both study groups at the pre-surgery clinic as compared to the pre-BS committee (P ≤ 0.028), but the improvement in the nutrition knowledge score was significantly higher for the intervention group (P = 0.030). No within or between-group differences were found for the trait anxiety items score. The "dream" and "realistic" weight goals were lower than the expected weight loss according to 70% excess weight loss (EWL) for both study groups at both time-points (P < 0.001 for all). Education by an online lecture prior to the surgery improves BS nutrition knowledge, but not anxiety. ClinicalTrials.gov number: NCT02857647.

The aim of this study was to investigate the effect of the submucosal injection of 1ml dexamethasone (4mg/ml) on pain, swelling, and trismus following the extraction of retained lower third molars. Ninety patients (mean age 23.5 years) were split randomly into three equal study groups (30 patients in each): the 'before' group received dexamethasone 15min before surgery and placebo 15min after surgery; the 'after' group received placebo 15min before surgery and dexamethasone 15min after surgery; the 'placebo' group received placebo 15min before surgery and placebo 15min after surgery. Postoperative pain was recorded by the patients using a visual analogue scale, numerical rating scale, and the McGill Pain Questionnaire at 1, 2, 4, 6, 8, 12, and 24h after surgery. The patients also recorded the total number of analgesic doses consumed during the 24h after the procedure. Swelling (determined using linear measurements of the face) and trismus (determined through measurement of maximum mouth opening) were assessed at 48h, 72h, and 7 days following surgery. Better control of pain, swelling, and trismus was demonstrated for dexamethasone in comparison to placebo. Postoperative dexamethasone provided better pain control than preoperative dexamethasone. There was no difference in total rescue analgesic intake between the preoperative and postoperative dexamethasone groups.

In the aging society, there is a growing number of patients with advanced degenerative disease of the spine. These patients frequently require surgical treatment. This paper aims to analyse the reasons for failure of surgery for degenerative disease of the lumbar spine. Histories of patients operated on by one group of surgeons in the Neuroorthopaedic Department of "STOCER" in 2014 and 2015 due to degenerative disease of the lumbar spine were analysed retrospectively. Out of the cohort, patients who had undergone a revision surgery were selected for the study and divided into two groups: group A (60) of patients previously operated on in another centre and group B (47) of patients previously operated on in "STOCER". The reasons for failure of the surgery were analysed in detail based on history, physical examination, imaging studies and surgery reports. Surgery was performed in 601 patients, of whom 107 patients had been previously operated on. The most frequent reasons for revision surgery of the same motor segment were recurrent disc herniation, inadequate decompression and inappropriate surgical technique. In the group of patients who had implants inserted to stabilise the spine, the revision surgery in most cases was due to adjacent segment disease. Use of implants and spinal fusion is always associated with a risk of complications and is frequently independent of the surgeon. 2. In order to reduce the rate of revision surgeries, it is important to perform complete decompression and select an adequate surgical technique.

Does surgery for deep infiltrating endometriosis (DIE) before in vitro fertilization (IVF) improve pregnancy and birth rate? Cohort study of 177 consecutive patients with DIE related infertility and receiving IVF. Patients were divided into 3 groups according to surgical management decided during multidisciplinary team meeting. Group no surgery (NS) (n=65), group complete surgery (CS) with complete resection of all lesions (n=49) and group incomplete surgery (IS) with gestures improving ovaries accessibility for IVF and/or facilitating embryonic implantation (n=63). Pre-surgery clinical, MRI lesion locations, and history of IVF characteristics were analyzed with logistic regression. There was no significant difference in general and IVF characteristics and in the severity of endometriosis among the three groups (P=0.43). Overall pregnancy and birth rates after IVF were 45.8% and 33.3%, respectively and were not different among the 3 groups (P=0.59 and P=0.49). Four major complications during oocytes retrievals were observed in NS group, one in IS group and none in CS group. Presence of an inter-utero-rectal lesion at MRI decreased the rate of pregnancy (OR=0.49 [0.25, 0.97]). Surgery for deep infiltrating endometriosis does not improve pregnancy and birth rates before IVF. This inter-utero-rectal extensive lesion might explain IVF failures by ovarian difficult access and difficulties in embryonic transfers. Further studies should explore the impact of surgical excision of inter-utero-rectal lesion on oocyte retrieval and embryonic transfer. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Surgical wound infections are more frequent in patients undergoing heart transplantation than in other heart surgery patients. There is a wide spread of sternal wound infection incidence in transplant patients ranging from 4% to 40%. It is first study describing local gentamicin sponge application during heart transplantation procedure. We enrolled 75 patients in a retrospective, single-center study, including 25 patients who underwent orthotopic heart transplantation (heart transplant group) and 50 in the cardiac surgery group. They were in mean age of 49 ± 12 years and 51 ± 13 years in heart transplantation and cardiac surgery group, respectively. A gentamicin sponge was inserted intraoperatively between sternal borders before chest closure in all heart transplantation patients. There was 1 early death (4%) on postoperative day 7 owing to Clostridium difficile infection in the heart transplant group. There was 1 death (2%) in the cardiac surgery group owing to multiorgan failure secondary to perioperative heart ischemia. There was neither bacterial sternal wound infection nor sternal instability in the heart transplant group. None of the patients who had gentamicin sponge applied had wound healing problems. Two patients (4%) had a deep sternal wound infection in the cardiac surgery group, who had no sponge application; 1 (2%) was treated by surgical debridement and active drainage and 1 (2%) by vacuum therapy. There were 11 patients (44%) discharged on insulin therapy in the heart transplant group and 21 (21%) in the cardiac surgery group. Mean overall postoperative hospital stay was 35 ± 19 days in the heart transplant group and 10 ± 4 days in the cardiac surgery group. Gentamicin sponge is an effective local infection prophylaxis in heart transplant patients. Copyright © 2015 Elsevier Inc. All rights reserved.

Background During head and neck surgery including orthognathic surgery, mild intraoperative hypothermia occurs frequently. Hypothermia is associated with postanesthetic shivering, which may increase the risk of other postoperative complications. To improve intraoperative thermoregulation, devices such as forced-air warming blankets can be applied. This study aimed to evaluate the effect of supplemental forced-air warming blankets in preventing postanesthetic shivering. Methods This retrospective study included 113 patients who underwent orthognathic surgery between March and September 2015. According to the active warming method utilized during surgery, patients were divided into two groups: Group W (n = 55), circulating-water mattress; and Group F (n = 58), circulating-water mattress and forced-air warming blanket. Surgical notes and anesthesia and recovery room records were evaluated. Results Initial axillary temperatures did not significantly differ between groups (Group W = 35.9 ± 0.7℃, Group F = 35.8 ± 0.6℃). However, at the end of surgery, the temperatures in Group W were significantly lower than those in Group F (35.2 ± 0.5℃ and 36.2 ± 0.5℃, respectively, P = 0.04). The average body temperatures in Groups W and F were, respectively, 35.9 ± 0.5℃ and 36.2 ± 0.5℃ (P = 0.0001). In Group W, 24 patients (43.6%) experienced postanesthetic shivering, while in Group F, only 12 (20.7%) patients required treatment for postanesthetic shivering (P = 0.009, odds ratio = 0.333, 95% confidence interval: 0.147–0.772). Conclusions Additional use of forced-air warming blankets in orthognathic surgery was superior in maintaining normothermia and reduced the incidence of postanesthetic shivering. PMID:28879279

Obesity is a major public health problem leading to co-morbidities such as diabetes, hypertension and kidney failure. Bariatric surgery results in pronounced and maintained weight loss and prevention of obesity-related diseases and their complications. Most studies of bariatric surgery on kidney disease show improvements after surgery. However, long-term studies analyzing hard end-points are lacking. Here we report on the long-term effects of bariatric surgery compared to usual obesity care on incidence of end-stage renal disease (ESRD) alone and in combination with chronic kidney disease stage 4 (CKD4/ESRD). 4047 patients were included in the Swedish Obese Subjects (SOS) study. Inclusion criteria were age 37-60 years and BMI ≥ 34 in men and BMI ≥ 38 in women. Patients in the bariatric surgery group (N = 2010) underwent banding (18%), vertical banded gastroplasty (69%), or gastric bypass (13%); controls (N = 2037) received usual obesity care. In this analysis, patients were followed up for a median time of 18 years. The incidence of ESRD and CKD4 was obtained by crosschecking the SOS database with the Swedish National Patient Register. During follow-up, ESRD occurred in 13 patients in the surgery group and in 26 patients in the control group (adjusted hazard ratio (HR) = 0.27; 95% CI 0.12-0.60; p = 0.001). The number of CKD4/ESRD events was 23 in the surgery group and 39 in the control group (adjusted HR = 0.33; 95% CI 0.18-0.62; p < 0.001). In both analyses, bariatric surgery had a more favorable effect in patients with baseline serum insulin levels above median compared to those with lower insulin levels (interaction p = 0.010). Treatment benefit of bariatric surgery was also greater in patients with macroalbuminuria at baseline compared to those without macroalbuminuria (interaction p < 0.001). Our study showed for the first time that bariatric surgery is associated with a long-term protection against ESRD and CKD4/ESRD.

Despite several experimental studies on the role of S100B and NSE in fractures, no studies on the influence of surgery on the biomarker serum levels have been performed yet. The serum levels of S100B and NSE were analysed in patients with fractures that were located in the spine (group 1, n = 35) or in the lower extremity (group 2, n = 32) pre- and post-operatively. The mean S100B serum level showed a significant increase (p = 0.04) post-surgery in the patients of group 1. In patients undergoing acute surgery (< 24 hours) the mean S100B serum level was 0.23 ± 0.22 μg L(-1) pre-operatively and 1.24 ± 1.38 μg L(-1) post-operatively. Likewise, the mean S100B serum level significantly increased in group 2 after surgery (p < 0.0001). In this group patients undergoing acute surgery showed a mean S100B serum level of 0.23 ± 0.14 μg L(-1) and 1.11 ± 0.73 μg L(-1) pre- and post-operatively. This study demonstrates significant alterations of the biomarker S100B serum levels in patients undergoing surgery. Higher S100B serum levels were found within 24 hours and might be related to the acute fracture. The NSE serum levels were unchanged and this biomarker may offer the probability to serve as a future outcome predictor in studies with patients with traumatic brain injury and additional extracerebral injuries.

Postoperative pain due to tissue damage caused during surgery not only causes discomfort for the patients, but can also result in prolonged hospitalization, increased morbidity and respiratory disorders, and readmission to the hospital. For postoperative pain control, numerous methods and medications have been suggested, such as non-steroidal anti-inflammatory drugs (NSAIDs) and narcotics. Pethidine, as a narcotic analgesic, and ketorolac, as an NSAID, are widely used for pain control. Thus, in this study, the effects of these two drugs were studied and compared in terms of pain control after inguinal hernia surgery in children of 1-12 years of age. Sixty-six children undergoing inguinal herniorrhaphy were selected and randomly divided into 2 groups. The first group received 0.5 mg/kg ketorolac and the second group received 1 mg/kg pethidine during extubation. Postoperative pain (using Wong Baker pain scale) and complications were measured until 24 hours after surgery. Mean and standard deviations of postoperative pain 1 hour after surgery in the pethidin and ketorolac groups were 5.06 ± 1.41 and 3.88 ± 0.93, respectively. The scale was significantly lower in the ketorolac group (P < 0.001). Postoperative pain intensity 2 hours after surgery in these two groups was 4.48 ± 1.52 and 3.55 ± 1.15, respectively, and the difference between the two groups was significant (P = 0.006). The variation in postoperative pain intensity in the ketorolac group was statistically lower than the pethidin group (P = 0.020). CONCLUSION.

The purpose of this study was to determine the effect of music listening on postoperative anxiety and intubation time in patients undergoing cardiovascular surgery. Coronary artery disease and valvular heart disease affect approximately 15 million Americans and 5 million persons in the U.K. annually, with the majority of these patients being older adults. The anxiety experienced before, during and after surgery increases cardiovascular workload, thereby prolonging recovery time. Music listening as a nursing intervention has shown an ability to reduce anxiety. The study used a randomized control trial design. Sixty adults older than 65 years were randomly assigned to the control and the experimental groups. The experimental group listened to music during and after surgery, while the control group received standard postoperative care. The Spielberger State Trait Anxiety Inventory was administered to both groups before surgery and 3 days postoperatively. The mean of the differences between scores was compared using analysis of variance. Differences in mean intubation time were measured in both groups. Older adults who listened to music had lower scores on the state anxiety test (F = 5.57, p = .022) and had significantly fewer minutes of postoperative intubation (F = 5.45, p = .031) after cardiovascular surgery. Older adults undergoing cardiovascular surgery who listen to music had less anxiety and reduced intubation time than those who did not.

Aim: Preoperative fasting is an established procedure to be practiced for patients before surgery, but optimal preoperative fasting time still remains controversial. The aim of this study was to investigate the effect of “shortened preoperative fasting time” on the change in the amount of total body water (TBW) in elective surgical patients. TBW was measured by multi-frequency impedance method. Methods: The patients, who were scheduled to undergo surgery for stomach cancer, were divided into two groups of 15 patients each. Before surgery, patients in the control group were managed with conventional preoperative fasting time, while patients in the “enhanced recovery after surgery (ERAS)” group were managed with “shortened preoperative fasting time” and “reduced laxative medication.” TBW was measured on the day before surgery and the day of surgery before entering the operating room. Defecation times and anesthesia-related vomiting and aspiration were monitored. Results: TBW values on the day of surgery showed changes in both groups as compared with those on the day before surgery, but the rate of change was smaller in the ERAS group than in the control group (2.4±6.8% [12 patients] vs. −10.6±4.6% [14 patients], p<0.001). Defecation times were less in the ERAS group. Vomiting and aspiration were not observed in either group. Conclusion: The results suggest that preoperative management with “shorted preoperative fasting time” and “reduced administration of laxatives” is effective in the maintenance of TBW in elective surgical patients.

To compare functional and anatomical outcomes after idiopathic epiretinal membrane (ERM) peeling combined with phacoemulsification and intraocular lens implantation versus ERM peeling alone. A retrospective, non-randomised comparative case series study was conducted of 81 eyes from 79 patients who underwent ERM peeling at the Beth Israel Deaconess Medical Center between 2001 and 2010. Eyes that underwent combined surgery for ERM and cataracts (group 1) were compared with those that had ERM peeling alone (group 2) with respect to best-corrected visual acuity at 6 months and 1 year after surgery, postoperative central macular thickness (CMT) as measured on optical coherence tomography, and rates of complications, including elevated intraocular pressure (IOP), ERM recurrence and need for reoperation. Mean logMAR visual acuity improved significantly in both groups at 6 months (p<0.001) and 1 year (p<0.001) after surgery. There was no statistical difference between the two groups in visual acuity improvement at 6 months (p=0.108) or 1 year (p=0.094). Mean CMT of both groups also significantly decreased after surgery (p=0.002), with no statistical difference in CMT reduction between the two groups, but a trend toward less CMT reduction in group 1 (p=0.061). The rates of complications, including IOP elevation, ERM recurrence and frequency of reoperation, were similar in the two groups, with non-statistical trends toward greater ERM recurrence (p=0.084) and need for reoperation (p=0.096) in those that had combined surgery. Combined surgery for ERMs and cataracts may potentially be as effective as membrane peeling alone with respect to visual and anatomical outcomes. Further studies are necessary to determine if there may be greater ERM recurrence or need for reoperation after combined surgery.

Achieving weight loss after bariatric surgery depends on the individual's ability to sustain lifestyle changes involving dietary modifications. Presurgical dietary assessment is critical to evaluate usual dietary habits and identify the need for intervention before surgery. The objective of this study was to identify usual dietary habits of black and white women seeking bariatric surgery and to examine potential differences between these ethnic groups. An additional aim was to describe participants' plans to change dietary behaviors after surgery. This study examined data from an observational study sponsored by a benefits management group in Louisiana. In this cross-sectional study, a presurgical dietary assessment interview questionnaire collected information on dietary habits. Participants (n = 200) were adult women being screened for bariatric surgery; 54% were white, and 46% were black. Descriptive statistics were calculated and differences between groups were tested using 2-way analysis of the variance. Participants reported consuming fast food 2.9 ± 2.6 times per week, fried foods 2.1 ± 1.8 times per week, and desserts 3.4 ± 3.2 times per week. Blacks reported more frequent consumption of fast food (P<.01), sugar-sweetened sodas (P<.05), and sugar-sweetened tea (P<.01) compared with whites. Plans for changing dietary behaviors after surgery were similar between ethnic groups. Findings indicated that frequent consumption of fast foods, fried foods, desserts, and sugar-sweetened beverages was common among women seeking bariatric surgery. Blacks tended to consume these foods and beverages more often than whites. Current dietary habits and future plans to change dietary behaviors should be addressed before surgery for success. Follow-up studies investigating the assessment instrument's ability to predict dietary adherence and weight loss after surgery are warranted. Copyright © 2018 American Society for Bariatric Surgery.

The use of a self-expanding metallic stent as a bridge to surgery in acute malignant left colonic obstruction has been suggested as an alternative treatment to emergency surgery. The aim of the present study was to compare the morbi-mortality, cost-benefit and long-term oncological outcomes of both therapeutic options. This is a prospective, comparative, controlled, non-randomized study (2005-2010) performed in a specialized unit. The study included 82 patients with left colon cancer obstruction treated by stent as a bridge to surgery (n=27) or emergency surgery (n=55) operated with local curative intention. The main outcome measures (postoperative morbi-mortaliy, cost-benefit, stoma rate and long-term oncological outcomes) were compared based on an "intention-to-treat" analysis. There were no significant statistical differences between the two groups in terms of preoperative data and tumor characteristics. The technically successful stenting rate was 88.9% (11.1% perforation during stent placement) and clinical success was 81.4%. No difference was observed in postoperative morbi-mortality rates. The primary anastomosis rate was higher in the bridge to surgery group compared to the emergency surgery group (77.8% vs. 56.4%; P=.05). The mean costs in the emergency surgery group resulted to be €1,391.9 more expensive per patient than in the bridge to surgery group. There was no significant statistical difference in oncological long-term outcomes. The use of self-expanding metalllic stents as a bridge to surgery is a safe option in the urgent treatment of obstructive left colon cancer, with similar short and long-term results compared to direct surgery, inferior mean costs and a higher rate of primary anastomosis.

To examine the effects of therapeutic play intervention on outcomes of children undergoing day surgery, and to highlight the importance of parental involvement in the psychoeducational preparation of children for surgery. A randomized controlled trial, two group pre-test and repeated post-test, between subjects design was employed. Hong Kong Chinese children (7-12 years of age; n=203) admitted for elective surgery in a day surgery unit, along with their parents during a 13-month period, were invited to participate in the study. By using a simple complete randomization method, 97 of children with their parents were assigned to the experimental group receiving therapeutic play intervention, and 106 children with their parents were assigned to the control group receiving routine information preparation. The results showed that both children and their parents in the experimental group reported lower state anxiety scores in pre- and post-operative periods. Children in the experimental group exhibited fewer instances of negative emotional behaviors and parents in the experimental group reported greater satisfaction. The results, however, find no differences in children's post-operative pain between the two groups. The study provides empirical evidence to support the effectiveness of using therapeutic play intervention and the importance of parental involvement in the psychoeducational preparation of children for surgery. The findings heighten the awareness of the importance of integrating therapeutic play and parental involvement as essential components of holistic and quality nursing care to prepare children for surgery.

The accuracy of pedicle screw placement was evaluated in posterior scoliosis surgeries with or without the use of computer-assisted surgical techniques. In this retrospective cohort study, the pedicle screw placement accuracy in posterior scoliosis surgery was compared between conventional fluoroscopic and computer-assisted surgical techniques. There has been no study systemically analyzing the perforation pattern and comparative accuracy of pedicle screw placement in posterior scoliosis surgery. The 45 patients who received posterior correction surgeries were divided into 2 groups: Group C, manual control (25 patients); and Group N, navigation surgery (20 patients). The average Cobb angles were 73.7 degrees and 73.1 degrees before surgery in Group C and Group N, respectively. Using CT images, vertebral rotation, pedicle axes as measured to anteroposterior sacral axis and vertebral axis, and insertion angle error were measured. In perforation cases, the angular tendency, insertion point, and length abnormality were evaluated. The perforation was observed in 11% of Group C and 1.8% in Group N. In Group C, medial perforations of left screws were demonstrated in 8 of 9 perforated screws and 55% were distributed either in L1 or T12. The perforation consistently occurred in pedicles in which those axes approached anteroposterior sacral axis within 5 degrees . The average insertion errors were 8.4 degrees and 5.0 degrees in Group C and Group N, respectively, which were significantly different (P < 0.02). The medial perforation in Group C occurred around L1, especially when pedicle axis approached anteroposterior sacral axis. This consistent tendency was considered as the limitation of fluoroscopic screw insertion in which horizontal vertebral image was not visible. The use of surgical navigation system successfully reduced the perforation rate and insertion angle errors, demonstrating the clear advantage in safe and accurate pedicle screw placement of scoliosis surgery.

The aim of this study was to determine the influence of music on anxiety levels and physiologic parameters in women undergoing gynecologic surgery. This study employed a pre- and posttest experimental design with nonrandom assignment. Ninety-seven women undergoing gynecologic surgery were included in the study, where 49 were allocated to the control group (nonmusic group) and 48 were assigned to the experimental group (music group). Preoperative anxiety was measured using the State Trait Anxiety Inventory (STAI) while noninvasive instruments were used in measuring the patients' physiologic parameters (blood pressure [BP], pulse [P], and respiration [R]) at two time periods. Women allocated in the experimental group had lower STAI scores (t = 17.41, p < .05), systolic (t = 6.45, p < .05) and diastolic (t = 2.80, p < .006) BP, and P rate (PR; t = 7.32, p < .05) than in the control group. This study provides empirical evidence to support the use of music during the preoperative period in reducing anxiety and unpleasant symptoms in women undergoing gynecologic surgery. © The Author(s) 2014.

Increased infection risk in inflammatory rheumatic diseases may be due to inflammation or immunosuppressive treatment. The influence of tumor necrosis factor (TNF) inhibitors on the risk of developing surgical site infections (SSIs) is not fully known. We compared the incidence of SSI after elective orthopedic surgery or hand surgery in patients with a rheumatic disease when TNF inhibitors were continued or discontinued perioperatively. We included 1,551 patients admitted for elective orthopedic surgery or hand surgery between January 1, 2003 and September 30, 2009. Patient demographic data, previous and current treatment, and factors related to disease severity were collected. Surgical procedures were grouped as hand surgery, foot surgery, implant-related surgery, and other surgery. Infections were recorded and defined according to the 1992 Centers for Disease Control definitions for SSI. In 2003-2005, TNF inhibitors were discontinued perioperatively (group A) but not during 2006-2009 (group B). In group A, there were 28 cases of infection in 870 procedures (3.2%) and in group B, there were 35 infections in 681 procedures (5.1%) (p = < 0.05). Only foot surgery had significantly more SSIs in group B, with very low rates in group A. In multivariable analysis with groups A and B merged, only age was predictive of SSI in a statistically significant manner. Overall, the SSI rates were higher after abolishing the discontinuation of anti-TNF perioperatively, possibly due to unusually low rates in the comparator group. None of the medical treatments analyzed, e.g. methotrexate or TNF inhibitors, were significant risk factors for SSI. Continuation of TNF blockade perioperatively remains a routine at our center.

Nowadays, pain, nausea, and vomiting are regarded as important complications of anesthesia and surgery. The current study aimed at assessing the effect of preemptive intravenous acetaminophen on control of pain, nausea, vomiting, shivering, and drowsiness following the general anesthesia for retina and/or vitrectomy surgeries. In a randomized, double-blind, clinical trial, 83 candidates for retina or vitrectomy eye surgery under general anesthesia were distributed into 3 groups: A) 41 patients in the control group who received 100 mL of normal saline just before the surgery and 100 mL of normal saline 20 minutes before the end of surgery; B) 21 patients in the preemptive group who received acetaminophen 15 mg/kg in 100 mL normal saline just before the surgery and 100 mL normal saline 20 minutes before the end of surgery; C) 21 patients in the preventive group who received 100 mL normal saline just before the surgery and acetaminophen 15 mg/kg in 100 mL normal saline 20 minutes before the end of surgery. Pain, nausea, vomiting, and shivering were assessed at the recovery and 2, 4, and 24 hours after the operation. Anesthesia emergence situation was assessed after arrival in the recovery room by the Richmond agitation-sedation scale (RASS) questionnaire. Blood pressure and heart rate were recorded before anesthesia induction, just after intubation, before extubation, and on discharge from the recovery room. Total intraoperative fentanyl, duration of operation, and duration of anesthesia were not different among the studied groups. Vital signs were not statistically different among the groups at before anesthesia induction, just after intubation, before extubation, and on discharge from the recovery room. Thirty-three patients in the control group (87.8%), 11 in preemptive (52.4%), and 14 in preventive groups (66.7%) needed acetaminophen in the first 24 hours after the surgery (P value = 0.008). Pain scores measured by visual rating scale (VRS) was lower in the preemptive and preventive groups, compared with those of the control group, in the recovery (P value = 0.006), 2 hours after the surgery (P value = 0.008), and 4 hours after the surgery (P value = 0.012), but not in 24 hours after the operation (P value = 0.1). Intravenous acetaminophen administered as preemptive or preventive medication was effective and safe to control acute postoperative pain and analgesic request after the vitrectomy eye surgery.

Rajyoga meditation is a form of mind body intervention that is promoted by the Brahma Kumaris World Spiritual University. This form of meditation can be easily performed without rituals or mantras and can be practiced anywhere at any time. The practice of Rajyoga meditation can have beneficial effects on modulating anxiety and cortisol level in patients undergoing major cardiac surgery. A prospective randomized control study was carried out in a single tertiary care center. One hundred and fifty patients undergoing elective coronary artery bypass surgery were enrolled in the study. The patients were randomized in two groups namely, Group 1 (Rajyoga group) and Group 2 (Control Group). Anxiety was measured on a visual analog scale 1-10 before the start of Rajyoga training or patient counseling (T1), on the morning of the day of surgery (T2), on the 2nd postoperative day (T3), and on the 5th postoperative day (T4). The serum cortisol level was measured in the morning of the day of surgery (T1), on the 2nd postoperative day (T2) and on the 5th postoperative day (T3), respectively. In the study, it was seen that the anxiety level of the patients before the surgery (T1) and on the day of surgery (T2) were comparable between the two groups. However on the 2nd postoperative day (T3), the patients who underwent Rajyoga training had lower anxiety level in comparison to the control group (3.12 ± 1.45 vs. 6.12 ± 0.14, P < 0.05) and on the 5th postoperative day (T4) it was seen that Rajyoga practice had resulted in significant decline in anxiety level (0.69 ± 1.1 vs. 5.6 ± 1.38, P < 0.05). The serum cortisol level was also favorably modulated by the practice of Rajyoga meditation. Mindbody intervention is found to effective in reducing the anxiety of the patients and modulating the cortisol level in patients undergoing wellknown stressful surgery like coronary artery bypass surgery.

We examined the effectiveness of tranexamic acid in preventing intraoperative blood loss during major cardiac surgery. Out of initial 81 patients undergoing major cardiac surgery (both coronary artery bypass and valve repair procedures) at our teaching hospital, sixty-seven patients were selected for this study. We compared estimated blood loss, decrease in percent hemoglobin and hematocrit following surgery between two groups of patients (none of them received any blood product during surgery), one group receiving no tranexamic acid (n=17) and another group receiving tranexamic acid (n=25). In the second study, we combined these patients with patients receiving modest amounts of blood products (1-2 unit) and compared these parameters between two groups of patients (25 patients received no tranexamic acid, 42 patients received tranexamic acid). In patients who received no blood product during surgery, those who received no tranexamic acid showed statistically significant (independent t-test two tailed at p <0.05) reduced estimated blood loss (mean: 713.5 mL, SD: 351.6, n=17) compared to those who received tranexamic acid (mean: 987.2 mL, SD: 459.9, n=25). We observed similar results when the patients receiving no blood products and patients receiving modest amount of blood products were combined based on the use of tranexamic acid or not. No statistically significant difference was observed in percent reduced hemoglobin or hematocrit following surgery in any group of patients. We conclude that intraoperative antifibrinolytic therapy with tranexamic acid does not reduce intraoperative blood loss during major cardiac surgery which contradicts popular belief. © 2017 by the Association of Clinical Scientists, Inc.

To examine bowel wall edema development in laparoscopic and open major visceral surgery. In a prospective study, 47 consecutively operated patients with gastric and pancreatic resections were included. Twenty-seven patients were operated in a conventional open procedure (open group) and 20 in a laparoscopic fashion (lap group). In all procedures, a small jejunal segment was resected during standard preparation, of which we measured the dry-wet ratio. Furthermore, HE staining was performed for measuring of bowel wall thickness and edema assessment. Mean value (±std) of dry-wet ratio was significantly lower in the open than in the lap group (0.169 ± 0.017 versus 0.179 ± 0.015; p = 0.03) with the same amount of fluid administration in both groups and a longer infusion interval during laparoscopic surgery. Subgroup analyses (only pancreatic resections) still showed similar results. Histologic examination depicted a significantly larger bowel wall thickness in the open group. Laparoscopic surgery does not seem to lead to the bowel wall edema observed to occur in open surgery regardless of the degree of intravenous fluid administration, thus supporting its use even in major visceral surgery.

Research findings concerning cognitive effects of pediatric epilepsy surgery form an important basis for decisions about surgery. However, most follow-up studies have been of limited duration. In this study, a 2-year follow-up of intelligence was undertaken. Risk factors were analyzed. Included were 38 patients aged 3 to 17 years. Surgery was left in 19 patients and right in 19 patients. Types of surgery included temporal lobe resection (n = 23), extratemporal or multilobar resection (n = 8), and hemispherectomy (n = 7). The Wechsler Scales of Intelligence were administered presurgically, 6 months postsurgically, and 2 years postsurgically. No significant change in verbal or performance intelligence quotient (IQ) was demonstrated on a group level. Lateralization, type of surgery, age at surgery, sex, and presurgical IQ did not affect outcome. Across assessments, IQ scores of left-hemisphere patients were lower than those of right-hemisphere patients. Scores of patients in the hemispherectomy group were lower than those of the extratemporal or multilobar resection group, which were lower than the temporal lobe resection group. Scores improved significantly in six patients and deteriorated in seven. In conclusion, epilepsy surgery in children and adolescents does not, in general, have a significant impact on cognitive development in a 2-year perspective. In individual patients, poor seizure control and extensive surgery for Rasmussen's encephalitis were related to a deterioration of IQ.

Ultrasound-guided foam sclerotherapy and endovenous laser ablation are widely used alternatives to surgery for the treatment of varicose veins, but their comparative effectiveness and safety remain uncertain. In a randomized trial involving 798 participants with primary varicose veins at 11 centers in the United Kingdom, we compared the outcomes of foam, laser, and surgical treatments. Primary outcomes at 6 months were disease-specific quality of life and generic quality of life, as measured on several scales. Secondary outcomes included complications and measures of clinical success. After adjustment for baseline scores and other covariates, the mean disease-specific quality of life was slightly worse after treatment with foam than after surgery (P=0.006) but was similar in the laser and surgery groups. There were no significant differences between the surgery group and the foam or the laser group in measures of generic quality of life. The frequency of procedural complications was similar in the foam group (6%) and the surgery group (7%) but was lower in the laser group (1%) than in the surgery group (P<0.001); the frequency of serious adverse events (approximately 3%) was similar among the groups. Measures of clinical success were similar among the groups, but successful ablation of the main trunks of the saphenous vein was less common in the foam group than in the surgery group (P<0.001). Quality-of-life measures were generally similar among the study groups, with the exception of a slightly worse disease-specific quality of life in the foam group than in the surgery group. All treatments had similar clinical efficacy, but complications were less frequent after laser treatment and ablation rates were lower after foam treatment.

Arrhythmia occurring during and after surgery is one of the major complications in open-heart surgery. Dexmedetomidine is an intravenous alpha-2 agonist and very specific short-acting drug to protect the various organs against ischemic injuries and blood reflow. However, the effect of dexmedetomidine for preventing intraoperative heart arrhythmias has not been recognized. This study aimed to determine the effect of dexmedetomidine on the incidence rate of heart arrhythmias and anesthetic required in off-pump coronary artery bypass surgery. This randomized clinical trial was conducted on patients who were candidates for off-pump coronary artery bypass referring to Imam Reza Hospital of Mashhad, Iran, from July 2016 through January 2017. The patients were randomly assigned to two groups of intervention (infusion of 0.5 mcg/kg/h dexmedetomidine together with induction followed by infusion of 0.5 mcg/kg/h by the end of the surgery) or control (saline infusion). Mean arterial pressure (MAP) and heart rate (HR) were measured before induction, during surgery operation and ICU admission. Data were analyzed by SPSS version 18 using Chi Square and independent-samples t-test. A total of 76 patients with a mean age of 59.8 ± 8.2 years (in two groups of 38) were studied. The two groups had no statistically significant difference in terms of background variables. The MAP and HR values before induction, during surgery and ICU admission were significantly higher in the control group than in the intervention group (p=0.001). Out of the studied arrhythmias, the values of PAC (55.2% vs. 15.7%), PVC (81.5% vs. 21.0%), AF (26.3% vs. 7.8%), VTAC (21.0% vs. 2.6%) were significantly lower in dexmedetomidine group (p=0.001). It seems that dexmedetomidine administration during induction and surgery can cause significant reduction in most of the common arrhythmias in off-pump coronary bypass surgery. The use of dexmedetomidine maintains MAP and HR at significantly lower values, and changes compared to the control group as well as reduces the need for anesthetic compounds. The present study has been registered at the Iranian Registry of Clinical Trials (www.IRCT.IR) with a code of IRCT2016072413159N9 before starting the study. This study was fully sponsored by the Research Deputy at Mashhad University of Medical Sciences, Iran (grant number 941413).

To evaluate the learning curve of non-penetrating glaucoma surgery (NPGS). The study included 32 eyes of 27 patients' (20 male and 7 female) with medically uncontrolled glaucoma. Non-penetrating glaucoma surgeries performed by trainees under control of an experienced surgeon between 2005 and 2007 at our tertiary referral hospital were evaluated. Residents were separated into two groups. Humanistic training model applied to the one in the first group, he studied with experimental models before performing NPGS. Two residents in the second group performed NPGS after a conventional training model. Surgeries of the residents were recorded on video and intraoperative parameters were scored by the experienced surgeon at the end of the study. Postoperative intraocular pressure, absolute and total success rates were analyzed. In the first group 19 eyes of 16 patients and in the second group 13 eyes of 11 patients had been operated by residents. Intraoperative parameters and complication rates were not statistically significant between groups (p > 0.05, Chi-square). The duration of surgery was 32.7 ± 5.6 min in the first group and 45 ± 3.8 min in the second group. The difference was statistically significant (p < 0.001, Student's t test). Absolute and total success was 68.8 and 93.8% in the first group and 62.5 and 87.5% in the second group, respectively. The difference was not statistically significant. Humanistic and conventional training models under control of an experienced surgeon are safe and effective for senior residents who manage phacoemulsification surgery in routine cataract cases. Senior residents can practice these surgical techniques with reasonable complication rates.

Objective This study aimed to evaluate the effects of ultrasound-guided rectus sheath block in gynaecological surgery with Pfannenstiel incision. Methods After the approval of the ethics committee and the patients’ consent, 75 ASA I–II patients who were aged between 20 and 70 years and scheduled for a gynaecological surgery with Pfannenstiel incision were included in this study. After induction of general anaesthesia, patients were randomly divided into three groups. In Group UR patients (n=25), ultrasound-guided rectus sheath block with 0.25% levobupivacaine (0.2 mL kg−1) was performed. In Group SR patients (n=25), surgical rectus sheath block with 0.25% levobupivacaine (0.2 mL kg−1) was applied. In Group T (n=25) patients, tramadol (2 mg kg−1) was intravenously administered 30 min before the end of surgery. Patient-controlled analgesia device was established for postoperative pain relief in all groups. Haemodynamic data and inspired sevoflurane concentration were recorded during the operation. Pain scores, total tramadol consumption, supplemental analgesic requirement and side effects were postoperatively evaluated. Results Demographic characteristics, duration of surgery and haemodynamic parameters were similar between the groups. Inspired sevoflurane concentration (%) and VAS scores were significantly lower in Group UR than those in Groups SR and T. Total tramadol consumption was significantly lower in Groups UR and SR than that in Group T. There was no significant difference in the incidence of side effects. Conclusion This study demonstrates that ultrasound-guided rectus sheath block helps to provide the effective analgesia without any side effects compared with surgical rectus sheath block and intravenous tramadol for gynaecological surgery with Pfannenstiel incision.

Use of nonsteroidal anti-inflammatory drugs (NSAIDs) should be avoided in bariatric surgery patients. If use of an NSAID is inevitable, a proton pump inhibitor (PPI) should also be used. To determine the effect of an, compared to care-as-usual, additional intervention to reduce NSAID use in patients who underwent bariatric surgery, and to determine the use of PPIs in patients who use NSAIDs after bariatric surgery. A randomized controlled intervention study in patients after bariatric surgery. Patients were randomized to an intervention or a control group. The intervention consisted of sending a letter to patients and their general practitioners on the risks of use of NSAIDs after bariatric surgery and the importance of avoiding NSAID use. The control group received care-as-usual. Dispensing data of NSAIDs and PPIs were collected from patients' pharmacies: from a period of 6 months before and from 3 until 9 months after the intervention. Two hundred forty-eight patients were included (intervention group: 124; control group: 124). The number of users of NSAIDs decreased from 22 to 18 % in the intervention group and increased from 20 to 21 % in the control group (NS). The use of a PPI with an NSAID rose from 52 to 55 % in the intervention group, and from 52 to 69 % in the control group (NS). Informing patients and their general practitioners by letter, in addition to care-as-usual, is not an effective intervention to reduce the use of NSAIDs after bariatric surgery (trial number NTR3665).

The purpose of this study is to observe the affection of different clinical surgeries on alar nasal cartilages' growth and development. The experimental results can provide some theory basis for clinical surgeries. Twenty-eight New Zealand immature rabbits were used in this study, and divided into normal control group, hidden dissection group and cutting off alar nasal cartilages group randomly, which included 4,12 and 12 rabbits, separately. Arc incision were made on the mucous membrane of nasal cavity,and then dissect the alar nasal cartilages hidden or cut off the alar nasal cartilages, separately. The growth and development of the alar cartilage were observed at different stages after the surgery using histological and immuno-histochemical methods. Four weeks, eight weeks, twelve weeks and sixteen weeks after surgery, there were no significant differences in the indexes of chondrocytes between hidden dissection group and control group. In cutting off alar nasal cartilages group, fiber tissue were observed in the vacancy left after being cut off cartilages, and even mucous membrane tissue could be seen in some slices. There is no adverse influence on the growth and development of the alar cartilage after being hidden dissected. Contrarily, the restoring capability of transparent cartilage cannot counteract the injury resulted form the surgery after the alar nasal cartilages being cut off.

Trans-metatarsal operation to diabetic foot necrosis is a common procedure although only half of the patients do not need a second amputation due to surgery wound ischemia. No current tools are available for early prediction of surgery success and the clinical decision for a second operation may take weeks. Heparanase protein is involved in inflammation, angiogenesis and coagulation activation. The aim of the study was to evaluate heparanase level and procoagulant activity as an early predictor for success or failure of diabetic foot trans-metatarsal surgery. The study group included 40 patients with diabetic foot necrosis requiring trans-metatarsal surgical intervention. Eighteen patients designated as necrotic group, developed post-surgery necrosis at the surgery wound within the first month, requiring a second more proximal amputation. Skin biopsies from the proximal surgery edge were stained for heparanase, tissue factor (TF), TF pathway inhibitor (TFPI) and by hematoxylin and eosin. Plasma samples were drawn pre-surgery and at 1h, 1week and 1month post-surgery. Samples were tested for heparanase levels by ELISA and TF+heparanase activity, TF activity and heparanase procoagulant activity. Skin biopsy staining did not predict subsequent necrosis. In the non-necrotic group a significant rise in TF+heparanase activity, heparanase activity and heparanase levels were observed 1h and 1week post-surgery. The most significant increase was in heparanase procoagulant activity at the time point of 1h post-surgery (P<0.0001). Pre-surgery TF activity was significantly lower in the non-necrotic group compared to the necrotic group (P<0.05). Measuring heparanase procoagulant activity pre-surgery and 1h post-surgery could potentially serve as an early tool to predict the procedure success. The present results broaden our understanding regarding early involvement of heparanase in the wound healing process. Copyright © 2016 Elsevier Ltd. All rights reserved.

Tumors may induce systemic immune dysfunction, which can be aggravated by surgery and anesthesia/analgesia. Data on the effect of flurbiprofen preemptive analgesia on immune dysfunction is limited. The aim of this study was to investigate the effect of flurbiprofen preemptive analgesia on lymphocytes and natural killer (NK) cells in patients undergoing thoracotomy and thoracoscopy radical esophagectomy, and to explore the analgesic methods suitable for tumor patients. This was a randomized controlled pilot study of 89 patients with esophageal cancer treated with surgery at the Henan Cancer Hospital between January 1, 2015 and December 31, 2016. The patients were divided into three groups: group 1, thoracotomy; group 2, thoracoscopy and laparoscopic surgery; and group 3, flurbiprofen, thoracoscopy, and laparoscopic surgery. CD3+, CD19+, NK, CD4+, and CD8+ cells in whole blood were measured by flow cytometry 30 minutes before surgery (T0), at the end of the thoracic section of the procedure (T1), and at the end of the operation (T2). There were no significant differences in CD3+, CD19+, CD8+, NK, and CD4+ cells between the three groups or regarding the time points during the procedure (all P > 0.05). Thoracotomy and thoracoscopy surgery resulted in similar immunological outcomes. Flurbiprofen ester preemptive analgesia did not suppress the immune function in patients and could be a safe analgesic method for patients with esophageal cancer undergoing surgery. © 2017 The Authors.

A prospective, nonrandomized study. To evaluate the effectiveness of periodic intraoperative text messages (SMS) in reducing parental anxiety level during posterior spinal fusion (PSF) surgery for adolescent idiopathic scoliosis (AIS) patients. No studies have reported the use of intraoperative SMS to reduce level of anxiety in parents of patients who are undergoing AIS corrective surgery. Parents of 50 AIS patients were studied at two centers. Group 1 did not receive any SMS whereas those in Group 2 received periodic SMS. Parents' anxiety were assessed using a validated Visual Analog Scale for anxiety (VAS-A) and the anxiety component of the Hospital Anxiety Depression Score (HADS). The assessment was carried out at five different periods: (P1) 6 hours before the surgery; (P2) at separation in the operation theatre; (P3) 1 hour after commencement of surgery; (P4) immediately after completion of surgery; (P5) 1 day postsurgery. A total of 96 parents (47 fathers, 49 mothers) were involved in this study. Both groups were comparable in terms of demographics and education level. The mean VAS for Group 1 peaked at P2 and the HADS scores peaked at P3. The anxiety level of Group 1 remained high at P2, P3, and P4. There was a steady decline in parental anxiety in Group 2 from P1 to P5. There were significantly lower mean VAS score and HADS score for both father and mother in Group 2 during P3 and P4. The mean HADS scores for parents in Group 1 at P2 and P3 were higher than 8, which indicate abnormal anxiety. The anxiety levels of parents receiving the SMS were significantly lower than parents who did not receive any messages. Thus, intraoperative SMS is an effective intervention to decrease parental anxiety of AIS patients undergoing PSF surgery. 3.

The aim of this study was to evaluate the clinical efficacy and the effects on decreasing the recurrence of AFRS (allergic fungal rhinosinusitis) of a budesonide inhalation suspension delivered via transnasal nebulization to patients following endoscopic sinus surgery. Thirty-five patients were recruited into this study. Final diagnoses were reached using Bent and Kuhn's criteria. The eligible patients were randomly divided into two groups: the budesonide transnasal nebulization group (group A) and the topical nasal steroids group (group B). Nasal symptoms, Lund-Mackay scores, and Kupferberg grades were evaluated before surgery, after surgery and during the follow-up to assess the effects of these two approaches. A total of 30 patients with AFRS who were eligible were included in the study. Four of the 15 patients in group B (26.67%) developed recurrent disease, whereas no patients in group A developed recurrent disease. This difference was statistically significant (p=0.032). Nebulized budesonide is an effective and safe treatment for patients with AFRS following endoscopic sinus surgery, as evidenced by the reduced recurrence rate observed in the budesonide transnasal nebulization group relative to the topical nasal steroids group.

This study investigates the importance of communication in surgery and how delivering preoperative patient education can lead to better health outcomes postoperatively, via promoting tolerable pain scores and minimizing the use of narcotics after surgery. Patients who underwent outpatient surgery were randomly divided into groups to compare the pain scores of those who received preoperative patient education, the experimental group, and those who did not receive any form of patient education, the control group. Two weeks before surgery, the experimental group subjects received oral and written forms of patient education consisting of how the body responds to pain, and how endorphins cause natural analgesia. Moreover, patients were educated on the negative effects narcotics have on endorphin production and activity, as well as mechanisms of non-opioid analgesics. Of the 69 patients in the experimental group, 90% declined a prescription for hydrocodone after receiving preoperative education two weeks prior to surgery. The control group consisted of 66 patients who did not receive preoperative patient education and 100% filled their hydrocodone prescriptions. Patients in both groups were offered and received gabapentin and celecoxib preoperatively for prophylaxis of postoperative pain unless they declined. The control groups were found to have average pain scores significantly greater (P <.05) than the experimental groups and also a significantly longer (P <.005) duration of pain. This study illustrates the power of patient education via oral, written and visual communication, which can serve as an effective means to minimize narcotic analgesia after surgery.

The objective of this study was to compare coronary artery bypass graft (CABG) surgery with non-extracorporeal vs. extracorporeal circulation. The study outcomes included operative time, number of graft vessels, pulmonary infection rates, and systemic inflammatory markers. 96 patients received selective CABG, either with non-extracorporeal (study group; n = 48) or extracorporeal circulation (control group; n = 48). Operative time, pulmonary infection rates, and blood levels of inflammatory markers TNF-α, IL-6, and IL-8 before and 4, 24, and 48 hours after the surgery were quantified. Graft vessels were quantified using computed tomography. Operative time was significantly shorter in study group (4.58 ± 0.91 vs. 5.36 ± 1.12 hours in control group; p < 0.05). The number of graft vessels and pulmonary infection rates were comparable between both techniques. However, systemic inflammatory markers were significantly (p < 0.05) lower in study group at 4 and, partly, 24 hours after the surgery. Extracorporeal circulation prolongs operation and can aggravate systemic inflammatory response. Therefore, CABG with non-extracorporeal circulation offers more beneficial outcomes.

The aims of our study were to compare quality of life (QOL) in obese patients after bariatric surgery with that in controls seeking surgery and to investigate which factors are associated with QOL in the Moorehead-Ardelt Quality of Life Questionnaire II (MA II). This was a cross-sectional study. The operated group consisted of patients after laparoscopic sleeve gastrectomy or laparoscopic Roux-en-Y gastric bypass. The MA II was administered by e-mail to 305 patients 12-18 months after surgery. The control groups consisted of 101 obese patients. We compared the QOL scores and considered good and very good outcomes to be satisfactory. Multiple logistic regression and correlation analysis was performed to identify factors associated with QOL. In the operated group, the total MA II score was 1.70 ± 0.76, which was higher than 0.59 ± 1.17 in the control group. The score adjusted for the type of surgery was comparable. The prevalence of satisfactory QOL outcomes was similar in both post-operative subgroups and was still higher than in the control group. We identified four factors associated with higher QOL in obese patients. Weight loss was not correlated with total score in MAII. This study demonstrates that patients after bariatric surgery have a higher score in MA II, which reflects better QOL. The scoring adjusted by type of operation is comparable. QOL among obese patients is dependent on age, gender, history of bariatric surgery, and partnered status. Body mass reduction was not associated with outcome in MAII.

We sought to determine whether preoperative statin treatment is more effective in reducing, after cardiac surgery with cardiopulmonary bypass, systemic inflammatory response and myocardial damage markers in patients who have elevated preoperative interleukin-6 levels than in patients who have normal preoperative interleukin-6 levels. The study involved a prospective cohort of 164 patients who underwent coronary and valvular surgery with cardiopulmonary bypass. There were 2 study groups: group A (n = 60), patients with elevated preoperative interleukin-6 levels; and group B (n = 104), patients with normal preoperative interleukin-6 levels. Each group was subdivided according to whether patients were (group 1) or were not (group 2) treated preoperatively with statins. Accordingly, the subdivided study groups were A1 (n = 40), A2 (n = 20), B1 (n = 56), and B2 (n = 48). The plasma levels of proinflammatory interleukin-6 were measured 1, 6, 24, and >72 hours after surgery. The baseline, operative, and postoperative morbidity and mortality characteristics were similar in all groups. Group A1 had significantly lower levels of interleukin-6 and troponin I than did group A2 at all postoperative time points. Group B1 had significantly lower levels of interleukin-6 than did group B2 postoperatively. There were no significant differences in troponin I levels between groups B1 and B2. We conclude that, in patients with preoperative activation of the inflammatory system, preoperative treatment with statins is associated with lower postoperative interleukin-6 and troponin I levels after cardiac surgery with cardiopulmonary bypass.

The aim of this pilot study was to assess the effect of pre-operative inspiratory muscle training (IMT) on respiratory variables in patients undergoing major abdominal surgery. Respiratory muscle strength (maximum inspiratory [MIP] and expiratory [MEP] mouth pressure) and pulmonary functions were measured at least 2 weeks before surgery in 80 patients awaiting major abdominal surgery. Patients were then allocated randomly to one of four groups (Group A, control; Group B, deep breathing exercises; Group C, incentive spirometry; Group D, specific IMT). Patients in groups B, C and D were asked to train twice daily, each session lasting 15 min, for at least 2 weeks up to the day before surgery. Outcome measurements were made immediately pre-operatively and postoperatively. In groups A, B and C, MIP did not increase from baseline to pre-operative assessments. In group D, MIP increased from 51.5 cmH(2)O (median) pre-training to 68.5 cmH(2)O (median) post-training pre-operatively (P < 0.01). Postoperatively, groups A, B and C showed a fall in MIP from baseline (P < 0.01, P < 0.01) and P = 0.06, respectively). No such significant reduction in postoperative MIP was seen in group D (P = 0.36). Pre-operative specific IMT improves MIP pre-operatively and preserves it postoperatively. Further studies are required to establish if this is associated with reduced pulmonary complications.

This study prospectively measured teasing and emotional adjustment before and after ear reconstruction in younger and older children with microtia. Participants with isolated microtia (n = 28) were divided into two groups by age at surgery, with a younger group aged 3-5 years (n = 13) with a mean age of 4.0 (0.71) years at the time of surgery and an older group aged 6-10 years old (n = 15) with a mean age of 7.87 (1.30) years. Children and their parents were interviewed preoperatively and a year after surgery about teasing and emotions about their ear(s). Teasing began between the ages of 2.4-4.8 years. A third of the younger group and all of the older group reported preoperative teasing. Before surgery, the older group reported higher rates of negative emotions about their ear(s) and teasing was correlated for all ages with feeling sad, worried, and mad about their ear(s). After surgery, teasing and negative emotions significantly decreased with increased happiness about their ear(s). Postoperative teasing was correlated with trying to hide their ear(s). There were significant interactions from before to after surgery based on surgery age for frequency of teasing, sadness, and feeling mad, with the older group showing relatively greater change postoperatively. Teasing and negative emotions about their ear(s) decreased for all ages after surgery, with a potential protective factor seen in younger surgery age.

BACKGROUND Few long-term or controlled studies of bariatric surgery have been conducted to date. We report the 12-year follow-up results of an observational, prospective study of Roux-en-Y gastric bypass that was conducted in the United States. METHODS A total of 1156 patients with severe obesity comprised three groups: 418 patients who sought and underwent Roux-en-Y gastric bypass (surgery group), 417 patients who sought but did not undergo surgery (primarily for insurance reasons) (non-surgery group 1), and 321 patients who did not seek surgery (nonsurgery group 2). We performed clinical examinations at baseline and at 2 years, 6 years, and 12 years to ascertain the presence of type 2 diabetes, hypertension, and dyslipidemia. RESULTS The follow-up rate exceeded 90% at 12 years. The adjusted mean change from baseline in body weight in the surgery group was −45.0 kg (95% confidence interval [CI], −47.2 to −42.9; mean percent change, −35.0) at 2 years, −36.3 kg (95% CI, −39.0 to −33.5; mean percent change, −28.0) at 6 years, and −35.0 kg (95% CI, −38.4 to −31.7; mean percent change, −26.9) at 12 years; the mean change at 12 years in nonsurgery group 1 was −2.9 kg (95% CI, −6.9 to 1.0; mean percent change, −2.0), and the mean change at 12 years in nonsurgery group 2 was 0 kg (95% CI, −3.5 to 3.5; mean percent change, −0.9). Among the patients in the surgery group who had type 2 diabetes at baseline, type 2 diabetes remitted in 66 of 88 patients (75%) at 2 years, in 54 of 87 patients (62%) at 6 years, and in 43 of 84 patients (51%) at 12 years. The odds ratio for the incidence of type 2 diabetes at 12 years was 0.08 (95% CI, 0.03 to 0.24) for the surgery group versus nonsurgery group 1 and 0.09 (95% CI, 0.03 to 0.29) for the surgery group versus nonsurgery group 2 (P<0.001 for both comparisons). The surgery group had higher remission rates and lower incidence rates of hypertension and dyslipidemia than did nonsurgery group 1 (P<0.05 for all comparisons). CONCLUSIONS This study showed long-term durability of weight loss and effective remission and prevention of type 2 diabetes, hypertension, and dyslipidemia after Roux-en-Y gastric bypass.

This retrospective comparative study aims to explore the time courses of serum myoglobin (Mb) changes, and summarize our experience in treating patients with hypermyoglobinemia after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC).This study covered 60 patients with peritoneal carcinomatosis treated with CRS + HIPEC as the study group, and another 25 cancer patients treated with conventional extensive surgery without HIPEC as the control group from February to October 2016. In the study group, patients with postoperative hypermyoglobinemia were on a comprehensive treatment regimen consisting intravenous injection of sodium bicarbonate solution according to the Mb level. In the control group, patients were recorded and treated with the same regimen except for special sodium bicarbonate solution. The preoperative and postoperative serum Mb, blood urine nitrogen (BUN), and creatinine (Cr) levels were evaluated.There were no significantly difference between the 2 groups in serum Mb, BUN, and Cr levels before surgery. Postoperative serum Mb levels were elevated in both groups and significantly higher on postoperative 0 to 2 days (P < .05) in the study group than the control group. The peak value of serum Mb levels (426.65 ± 108.386 μg/L) occurred on the surgery day. The serum Mb change rate was much bigger in the study group than the control group. Serum BUN levels in both groups revealed a slow increase during the early postoperative period and were significantly lower in the study group than the control group on days 1 and 2. The serum Cr levels were similar and stable between the 2 groups after surgery. The serum Cr change rates changed synchronously with same tendency in both groups, and on postoperative day 1 the increase rate was bigger in the control group than the study group.Hypermyoglobinemia is a common and prominent lab abnormality after CRS + HIPEC, and serum Mb levels could be an early and sensitive indicator for dramatic disturbances in the internal milieu after CRS + HIPEC. Adequate treatment with sodium bicarbonate could accelerate the reduction in serum Mb levels and reduce the risk for major organ damages.

This study was an exploratory repeated measures design comparing patients undergoing two magnitudes of surgery in the lumbar spine: lumbar herniated disc repair and posterior lumbar fusion. The present study evaluated and compared the effect of perceived pain, perceived stress, anxiety, and mood on natural killer cell activity (NKCA) and IL-6 production among adult patients undergoing lumbar surgery. Presurgical stress and anxiety can lead to detrimental patient outcomes after surgery, such as increased infection rates. It has been hypothesized that such outcomes are due to stress-immune alterations, which may be further exacerbated by the extent of surgery. However, psychologic stress, anxiety, and mood have not been previously characterized in patients undergoing spinal surgery. Pain, stress, anxiety, and mood were measured using self-report instruments at T1 (1 week before surgery), T2 (the day of surgery), T3 (the day after surgery), and T4 (6 weeks after surgery). Blood (30 mL) was collected for immune assessments at each time point. Pain, stress, anxiety, and mood state were elevated at baseline in both surgical groups and were associated with significant reduction in NKCA compared with the nonsurgical control group. A further decrease in NKCA was observed 24 hours after surgery in both surgical groups with a significant rise in stimulated IL-6 production, regardless of the magnitude of surgery. In the recovery period, NKCA increased to or above baseline values, which correlated with decreased levels of reported pain, perceived stress, anxiety, and mood state. This study demonstrated that patients undergoing elective spinal surgery are highly stressed and anxious, regardless of the magnitude of surgery and that such psychologic factors may mediate a reduction in NKCA.

This study was designed to evaluate and compare the complication rates of patients having abdominoplasty without breast surgery with the rates of those having abdominoplasty with various types of elective breast surgery, including breast augmentation, breast reduction, mastopexy, and mastopexy combined with simultaneous augmentation. The data collected represent a retrospective chart review of consecutive abdominoplasty procedures performed at a single outpatient facility by the senior surgeon (W.G.S.) over a 15-year period (1989 to 2004). Two groups were compared: patients who underwent abdominoplasty without breast surgery and those who had abdominoplasty with breast surgery. The second group was subdivided by the various types of breast procedures noted above. The minor complications assessed included seromas, hematomas, infections, and small (<5 cm) wound breakdowns. Major complications evaluated included large (>5 cm) flap necrosis, need for blood transfusion, deep vein thrombosis, pulmonary embolus, myocardial infarction, and death. Additional data compiled included age, sex, tobacco use, body mass index, past medical history, American Society of Anesthesiologists physical status level, and operative times. Of the 415 abdominoplasty procedures, 264 (group 1) did not include simultaneous breast surgery. One hundred fifty-one procedures (group 2) involved simultaneous breast surgery, representing 36 percent of the total. Group 2 was further subdivided into those who had breast augmentation surgery (group 2A, n = 50), those who had breast reduction surgery (group 2B, n = 31), those who had mastopexy surgery (group 2C, n = 28), and those who had simultaneous mastopexy and breast augmentation surgery (group 2D, n = 42). Removal and replacement of implants and capsulectomy/capsulotomy procedures were included in the augmentation group (group 2A). There were no major complications, including flap necrosis (open wound >5 cm), blood transfusions, deep vein thrombosis, pulmonary embolus, myocardial infarction, or death. No patients required hospitalization. No statistically significant associations with complications were noted between groups 1 and 2 (chi-square, 0.0045; p > 0.95, not significant). Furthermore, when subdivided by type of breast surgery, no statistically significant associations were noted among subgroups: group 1 versus 2A (chi-square, 0.96; p > 0.05, not significant), group 1 versus 2B (chi-square, 0.032; p > 0.9, not significant), group 1 versus 2C (chi-square, 0.003; p > 0.975, not significant), and group 1 versus 2D (chi-square, 0.83; p > 0.5, not significant). The results of this retrospective review indicate that combining elective breast surgery with abdominoplasty does not appear to significantly increase the number of major or minor complications.

This study examined the effects of WeChat-assisted perioperative instructions for parents whose children were to undergo herniorrhaphy. A randomized controlled trial was conducted in a day surgery center in China. Participants were randomly assigned to the intervention (WeChat) group (n = 209) and the control (Leaflet) group (n = 209). The primary outcomes of this study were parents' knowledge regarding hernia and rate of cancellation of children's surgery. The secondary outcomes were the rate of lost-to-follow-up and the rate of complications and adverse events during the seventh postoperative follow-up day. There was a significant difference in the rate of cancelling the surgery and the mean knowledge score between the WeChat group and leaflet groups. The lost-to-follow-up rate was significantly lower in the WeChat group (0.54%) than in the leaflet group (3.66%). The incidence of postoperative complications were higher in the control group. WeChat-assisted perioperative care instructions enhanced parents' knowledge on perioperative instructions and promoted the preparation of their children for day surgery resulting in lower rate of cancelling the surgery. WeChat has the ability to expand health services outside the hospital confines and could be used as an important low-cost health educational medium in China. Copyright © 2018 Elsevier B.V.

Scoliosis surgery usually is associated with large volume of intraoperative blood loss, and cell salvage is used commonly to filter and retranfusion autologous blood to patients. The efficacy of using cell salvage in scoliosis surgery, however, is still controversial. The purpose of this study is to make clear that intraoperative use of cell salvage is effective to decrease the volume of perioperative allogenic blood transfusion in scoliosis surgery. A meta-analysis was conducted to identify the relevant studies from PubMed, Embase, Medline, Cochrane library, and Google scholar until July 2016. All randomized trials and controlled clinical studies comparing the clinical outcomes of using cell salvage versus noncell salvage in scoliosis surgery were retrieved for the meta-analysis. The data were analyzed by RevMan 5.3. A total of 7 studies with 562 patients were included in this meta-analysis. Based on the analysis, the volumes of perioperative and postoperative allogenic red blood cell (RBC) transfusion in cell salvage group were significantly less than those in control group (P = 0.04 and P = 0.01); however, no significant difference was detected in the amount of intraoperative allogenic RBC transfusion and the risk of patients needing allogenic blood transfusion between the 2 groups (P = 0.14 and P = 0.61). Both the hemoglobin and hematocrit levels on the first day after surgery were significantly greater in cell salvage group than those in control group (P = 0.002 and P < 0.001). No significant differences, however, were noted in neither hemoglobin nor hematocrit level at the time of discharge between the 2 groups (P = 0.76 and P = 0.32). One of the included study reported the number of patients with complications related to transfusion in the two groups, which was not significant different (P = 0.507). Cell salvage significantly reduced the volumes of perioperative and postoperative allogenic RBC transfusion in scoliosis surgery and increased the hemoglobin and hematocrit levels on the first day postoperatively. In addition, it seemed not to increase the rate of transfusion complications during the surgery. Copyright © 2017 Elsevier Inc. All rights reserved.

In severely obese individuals, reducing body weight induced by bariatric surgery is able to promote a reduction in comorbidities and improve respiratory symptoms. However, cardiorespiratory fitness (CRF) reflected by peak oxygen uptake (VO 2peak ) may not improve in individuals who remain sedentary post-surgery. The objective of this study was to evaluate the effects of a physical training program on CRF and pulmonary function in obese women after bariatric surgery, and to compare them to a control group. Twelve obese female candidates for bariatric surgery were evaluated in the preoperative, 3 months postoperative (3MPO), and 6 months postoperative (6MPO) periods through anthropometry, spirometry, and cardiopulmonary exercise testing (CPX). In the 3MPO period, patients were divided into control group (CG, n = 6) and intervention group (IG, n = 6). CG received only general guidelines while IG underwent a structured and supervised physical training program involving aerobic and resistance exercises, lasting 12 weeks. All patients had a significant reduction in anthropometric measurements and an increase in lung function after surgery, with no difference between groups. However, only IG presented a significant increase (p < 0.05) in VO 2peak and total CPX duration of 5.9 mL/kg/min (23.8%) and 4.9 min (42.9%), respectively. Applying a physical training program to a group of obese women after 3 months of bariatric surgery could promote a significant increase in CRF only in the trained group, yet also showing that bariatric surgery alone caused an improvement in the lung function of both groups.

Since the surgery for congenital heart disease (CHD) is considered highly risky, appropriate postoperative care is crucial. After the surgery, children are often discharged with unhealed wounds, incomplete recovery, and continuing pain. Health education programs based on empowerment education model can assist clients to develop skills in self-management. This study aimed to evaluate the effectiveness of an empowerment health education program for improving caregiving knowledge, caring behaviors, and self-efficacy of parents caring for children after corrective surgery for CHD. This prospective clinical trial enrolled pediatric patients undergoing surgical correction for CHD. Patients were divided into two groups: the control group (n = 42), which received the standard education program, and the intervention group (n = 44), which participated in the empowerment theory-based education program. We collected data on left ventricular ejection fraction (LVEF); peripheral oxygen saturation (SpO2); New York Heart Association classification of the patients; and the parents' caregiving knowledge, caring behaviors, and self-efficacy before surgery and one month and three months after surgery. At one month and three months after surgery, the intervention group scored higher than the control group in caregiving knowledge, caring behavior, and self-efficacy. By the third month after surgery, the intervention group had significantly higher values of LVEF and SpO2 than the control group. © The Author(s) 2015.

Most medical schools in the United States use the National Board of Medical Examiners Subject Examinations as a method of at least partial assessment of student performance, yet there is still uncertainty of how well these examination scores correlate with clinical proficiency. Thus, we investigated which factors in a surgery clerkship curriculum have a positive effect on academic achievement on the National Board of Medical Examiners Subject Examination in Surgery. A retrospective analysis of 83 third-year medical students at our institution with 4 unique clinical experiences on the general surgery clerkship for the 2007-2008 academic year was conducted. Records of the United States Medical Licensing Examination Step 1 scores, National Board of Medical Examiners Subject Examination in Surgery scores, and essay examination scores for the groups were compared using 1-way analysis of variance testing. Rush University Medical Center, Chicago IL, an academic institution and tertiary care center. Our data demonstrated National Board of Medical Examiners Subject Examination in Surgery scores from the group with the heavier clinical loads and least time for self-study were statistically higher than the group with lighter clinical services and higher rated self-study time (p = 0.036). However, there was no statistical difference of National Board of Medical Examiners Subject Examination in Surgery scores between the groups with equal clinical loads (p = 0.751). Students experiencing higher clinical volumes on surgical services, but less self-study time demonstrated statistically higher academic performance on objective evaluation, suggesting clinical experience may be of higher value than self-study and reading.

Synovial fluid was collected prior to and at 3 to 4 days after ACL reconstruction to investigate the correlation between inflammatory cytokine levels in the acute phase after surgery and physical functional recovery at 3 months postoperatively.  For this purpose, 79 patients with ACL reconstruction using semitendinosus tendons were included in the study. Median days from injury to surgery were 80 days (13-291 days). Synovial fluid was obtained just before surgery and at 3 to 4 days after surgery. Physical activity of each patient was evaluated at 3 months postoperatively, and scored from 0 (hard to walk) to 5 (run). Patients able to jog (score 4) or run (score 5) were considered as the "quick recovery" group and others (scores 1-3) as the "delayed recovery" group. Physical activity recovery scores in the early surgery group (preoperative period less than 60 days; Group I) were significantly better than those in the delayed surgery group (Group II). Among the cytokines tested, TNF-alpha and IL10 levels in synovial fluid were significantly higher in Group II at 3 to 4 days postoperatively, while levels of these cytokines were quite comparable preoperatively between the groups. Increased IL1-beta expression was noted in the delayed recovery group at 3 to 4 days postoperatively. In addition, levels of IL6, IL10 and IFN-gamma also tended to increase in patients with delayed recovery. Delayed ACL reconstruction increases levels of inflammatory cytokines in synovial fluid after surgery and correlates with a prolonged recovery of short-period physical activity of the patients.

Abstract The aim of the present study was to compare differential impacts of bariatric surgery and exercise-induced weight loss on excessive abdominal and cardiac fat deposition. Excessive fat accumulation around the heart may play an important role in the pathogenesis of cardiovascular disease. Recent evidences have suggested that bariatric surgery results in relatively less decrease in epicardial fat compared with abdominal visceral fat and paracardial fat. Sixty-four consecutive overweight or obese subjects were enrolled in the study. Clinical characteristics and metabolic profiles were recorded. The volumes of abdominal visceral adipose tissue (AVAT), abdominal subcutaneous adipose tissue (ASAT), epicardial (EAT), and paracardial adipose tissue (PAT) were measured by computed tomography in the bariatric surgery group (N = 25) and the exercise group (N = 39) at baseline and 3 months after intervention. Subjects in both the surgery and exercise groups showed significant reduction in body mass index (15.97%, 7.47%), AVAT (40.52%, 15.24%), ASAT (31.40, 17.34%), PAT (34.40%, 12.05%), and PAT + EAT (22.31%, 17.72%) (all P < 0.001) after intervention compared with baseline. In both the groups, the decrease in EAT was small compared with the other compartments (P < 0.01 in both groups). Compared with the exercise group, the surgery group had greater loss in abdominal and cardiac visceral adipose tissue (AVAT, ASAT, PAT, EAT+PAT) (P < 0.001), but lesser loss in EAT (P = 0.037). Compared with the exercise group, bariatric surgery results in significantly greater percentage loss of excessive fat deposits except for EAT. EAT, but not PAT, was relatively preserved despite weight reduction in both the groups. The physiological impact of persistent EAT deserves further investigation. PMID:26844473

Evidence regarding the efficacy of psychosocial interventions after bariatric surgery is rare and shows conflicting results. The Bariatric Surgery and Education (BaSE) study aimed to assess the efficacy of a psychoeducational group intervention in patients after bariatric surgery. The BaSE study was a randomized, controlled, multicenter clinical trial involving 117 patients who underwent bariatric surgery. Patients received either conventional postsurgical visits or, in addition, a 1-year psychoeducational group program. The present study evaluated the sustained effects of the intervention program. Mean follow-up duration was 37.9 months (standard deviation [SD] 8.2 months) after surgery. Outcome measures were as follows: body mass index (BMI), weight loss, self-efficacy, depression severity, and health-related quality of life (HRQOL). Groups were compared using an intention-to-treat approach with a mixed model for repeated measurements. A total of 74 patients (63.2%) completed the follow-up (T5) assessment. Mean weight loss for all patients was 43 kg (SD 15.5 kg) at T5 (mean BMI 35.1 kg/m 2 ). Mean excess weight loss was 60.4%. The effects of the surgery during the first postsurgical year were reflected, on average, by both decreasing weight and psychosocial burden. At the T5 time point, patients had slowly started to regain weight and to deteriorate regarding psychosocial aspects. However, at T5, patients who had participated in the intervention program (n = 39) showed significantly lower depression severity scores (p = .03) and significantly higher self-efficacy (p = .03) compared to the control group (n = 35). The 2 groups did not differ regarding weight loss and quality of life. Psychoeducational intervention shows sustained effects on both depression severity scores and self-efficacy.

To evaluate the effects of music listening on pain intensity and pain distress on the first and second postoperative days in abdominal surgery patients and the long-term effects of music on the third postoperative day. Music has been found to relieve pain intensity in surgery patients. There are only a few studies on music intervention in abdominal surgery. Music intervention studies assessing multidimensional pain such as pain intensity and pain distress are also scarce. Prospective clinical study with two parallel groups. Patients undergoing elective abdominal surgery (n = 168) were divided into either a music group (n = 83) or a control group (n = 85). Patients assessed pain intensity and pain distress in bed rest, during deep breathing and in shifting position once in the evening of the operation day and on the first and second postoperative days in the morning, at noon and in the evening. On the third postoperative day, the patients assessed their pain intensity and pain distress only once. In the music group, the patients' pain intensity and pain distress in bed rest, during deep breathing and in shifting position were significantly lower on the second postoperative day compared with control group of patients. On the third postoperative day, when long-term effects of music on pain intensity and pain distress were assessed, there were no significant differences between music and control groups. This study demonstrates that the use of music alleviates pain intensity and pain distress in bed rest, during deep breathing and in shifting position after abdominal surgery on the second postoperative day. Music intervention is safe, inexpensive and easily used to improve the healing environment for abdominal surgery patients. Music intervention should be offered as an adjunct alternative to pharmacological pain relief after abdominal surgery in nursing practice. © 2011 Blackwell Publishing Ltd.

We studied the effects of enteral nutrition (EN) support initiated 1 week before surgery on postoperative nutritional status, immune function, and inflammatory response in gastric cancer patients. A total of 200 gastric cancer patients were randomly divided into two groups: EN starting 1 week before surgery (study group) and EN starting early after surgery (control group). The two groups received EN support, following different therapeutic schedules, until the 9th day after operation. In the patients, body weight, skinfold thickness, upper-arm circumference, white blood cell count, albumin, prealbumin, C-reactive protein, peripheral immunoglobulins (IgA, IgG, and IgM), T lymphocyte subsets, interleukin-6, and tumor necrosis factor-α were measured 10 days before and after surgery and on the first day after surgery. There was no statistically significant difference in the results of recovery time of passage of gas by anus, abdominal distension, stomachache, blood glucose, hepatic and renal functions, and electrolytes between the two groups of patients (P > 0. 05). Adverse reactions occurred to both groups at 1 and 2 days after operation. Such conditions was improved after the intravenous drip rate was adjusted. The albumin and prealbumin levels of the patients in both groups decreased at 1 day after operation (P < 0. 05). The levels rose when the research was finished (P < 0. 05). The prealbumin level of the study group was higher than that of the control group at 10 days after operation (P < 0. 05). The IgG level of the study group was higher than that of the control group at 10 days after operation (P < 0. 05). The two groups of inflammatory reaction indicators of the study group were lower than those of the control group at 10 days after operation (P < 0. 05). This study indicates that appropriate preoperative EN support for gastric cancer patients can improve their postoperative nutritional status and immune function, can reduce inflammatory response, and is more conducive to the recovery of patients.

The purpose of this study was to construct a new clinical tool for establishing levels of indications for cataract surgery, and to validate this tool. Teams from nine eye clinics reached an agreement about the need to develop a clinical tool for setting levels of indications for cataract surgery and about the items that should be included in the tool. The tool was to be called 'NIKE' (Nationell Indikationsmodell för Kataraktextraktion). The Canadian Cataract Priority Criteria Tool served as a model for the NIKE tool, which was modified for Swedish conditions. Items included in the tool were visual acuity of both eyes, patients' perceived difficulties in day-to-day life, cataract symptoms, the ability to live independently, and medical/ophthalmic reasons for surgery. The tool was validated and tested in 343 cataract surgery patients. Validity, stability and reliability were tested and the outcome of surgery was studied in relation to the indication setting. Four indication groups (IGs) were suggested. The group with the greatest indications for surgery was named group 1 and that with the lowest, group 4. Validity was proved to be good. Surgery had the greatest impact on the group with the highest indications for surgery. Test-retest reliability test and interexaminer tests of indication settings showed statistically significant intraclass correlations (intraclass correlation coefficients [ICCs] 0.526 and 0.923, respectively). A new clinical tool for indication setting in cataract surgery is presented. This tool, the NIKE, takes into account both visual acuity and the patient's perceived problems in day-to-day life because of cataract. The tool seems to be stable and reliable and neutral towards different examiners.

Support following bariatric surgery is vital to ensure long-term postoperative success. Many individuals undergoing bariatric surgery are turning to online modalities, especially the popular social media platform Facebook, to access support groups and pages. Despite evidence suggesting that the majority of patients considering bariatric surgery are utilizing online groups, little is known about the actual content of these groups. The purpose of the present study was to conduct a content analysis of bariatric surgery support groups and pages on Facebook. Online via Facebook, independent academic medical center, United States. Data from bariatric surgery-related Facebook support groups and pages were extracted over a 1-month period in 2016. Salient content themes (e.g., progress posts, depression content, eating behaviors) were coded reliably (all κ> .70). More than 6,800 posts and replies were coded. Results indicated that seeking recommendations (11%), providing information or recommendations (53%), commenting on changes since surgery (19%), and lending support to other members (32%) were the most common types of posts. Content surrounding anxiety, eating behaviors, depression, body image, weight bias, and alcohol was found less frequently. Online bariatric surgery groups can be used to receive support, celebrate physical and emotional accomplishments, provide anecdotal accounts of the "bariatric lifestyle" for preoperative patients, and comment on challenges with mental health and experiences of weight bias. Providers should become acquainted with the content commonly found in online groups and exercise caution in recommending these platforms to information-seeking patients.

In a randomized, double-blind, prospective study, we have evaluated the effect of i.v. infusion of magnesium sulphate during spinal anaesthesia on postoperative analgesia and postoperative analgesic requirements. Forty patients undergoing total hip replacement arthroplasty under spinal anaesthesia were included. After the induction of spinal anaesthesia, the magnesium group (Group M) received magnesium sulphate 50 mg kg(-1) for 15 min and then 15 mg kg(-1) h(-1) by continuous i.v. infusion until the end of surgery. The saline group (Group S) received the same volume of isotonic saline over the same period. After surgery, a patient-controlled analgesia (PCA) device containing morphine and ketorolac was provided for the patients. Postoperative pain scores, PCA consumption, and the incidences of shivering, postoperative nausea, and vomiting were evaluated immediately after surgery, and at 30 min, 4, 24, and 48 h after surgery. Serum magnesium concentrations were checked before the induction of anaesthesia, immediately after surgery, and at 1 and 24 h after surgery. Postoperative pain scores were significantly lower in Group M at 4, 24, and 48 h after surgery (P<0.05). Cumulative postoperative PCA consumptions were also significantly lower in Group M at 4, 24, and 48 h after surgery (P<0.05). Postoperative magnesium concentrations were higher in Group M (P<0.05 at 4, 24, and 48 h after surgery), but no side-effects associated with hypermagnesemia were observed. Haemodynamic variables and the incidences of shivering, nausea, and vomiting were similar in the two groups. I.V. magnesium sulphate administration during spinal anaesthesia improves postoperative analgesia.

OBJECTIVE Pain control is an important clinical consideration and quality-of-care metric. No studies have examined postoperative pain control following transsphenoidal surgery for pituitary lesions. The study goals were to 1) report postoperative pain scores following transsphenoidal surgery, 2) determine if multimodal opioid-minimizing pain regimens yielded satisfactory postoperative pain control, and 3) determine if intravenous (IV) ibuprofen improved postoperative pain scores and reduced opioid use compared with placebo. METHODS This study was a single-center, randomized, double-blinded, placebo-controlled intervention trial involving adult patients with planned transsphenoidal surgery for pituitary tumors randomized into 2 groups. Group 1 patients were treated with scheduled IV ibuprofen, scheduled oral acetaminophen, and rescue opioids. Group 2 patients were treated with IV placebo, scheduled oral acetaminophen, and rescue opioids. The primary end point was patient pain scores (visual analog scale [VAS], rated 0-10) for 48 hours after surgery. The secondary end point was opioid use as estimated by oral morphine equivalents (OMEs). RESULTS Of 136 patients screened, 62 were enrolled (28 in Group 1, 34 in Group 2). The study was terminated early because the primary and secondary end points were reached. Baseline characteristics between groups were well matched except for age (Group 1, 59.3 ± 14.4 years; Group 2, 49.8 ± 16.2 years; p = 0.02). Mean VAS pain scores were significantly different, with a 43% reduction in Group 1 (1.7 ± 2.2) compared with Group 2 (3.0 ± 2.8; p < 0.0001). Opioid use was significantly different, with a 58% reduction in Group 1 (26.3 ± 28.7 mg OME) compared with Group 2 (62.5 ± 63.8 mg OME; p < 0.0001). CONCLUSIONS Multimodal opioid-minimizing pain-management protocols resulted in acceptable pain control following transsphenoidal surgery. IV ibuprofen resulted in significantly improved pain scores and significantly decreased opioid use compared with placebo. Postoperative multimodal pain management, including a nonsteroidal antiinflammatory medication, should be considered after surgery to improve patient comfort and to limit opioid use.

Surgeons are increasingly confronted by patients on long-term low-dose acetylsalicylic acid (ASA). However, owing to a lack of evidence-based data, a widely accepted consensus on the perioperative management of these patients in the setting of non-cardiac surgery has not yet been reached. Primary objective was to evaluate the safety of continuous versus discontinuous use of ASA in the perioperative period in elective general or abdominal surgery. Fifty-two patients undergoing elective cholecystectomy, inguinal hernia repair or colonic/colorectal surgery were recruited to this pilot study. According to cardiological evaluation, non-high-risk patients who were on long-term treatment with low-dose ASA were eligible for inclusion. Patients were allocated randomly to continuous use of ASA or discontinuation of ASA intake for 5 days before until 5 days after surgery. The primary outcome was the incidence of major haemorrhagic and thromboembolic complications within 30 days after surgery. A total of 26 patients were allocated to each study group. One patient (3.8%) in the ASA continuation group required re-operation due to post-operative haemorrhage. In neither study group, further bleeding complications occurred. No clinically apparent thromboembolic events were reported in the ASA continuation and the ASA discontinuation group. Furthermore, there were no significant differences between both study groups in the secondary endpoints. Perioperative intake of ASA does not seem to influence the incidence of severe bleeding in non-high-risk patients undergoing elective general or abdominal surgery. Further, adequately powered trials are required to confirm the findings of this study.

Surgery is supposed to modulate the production of carbon monoxide by the reduction of heme oxygenase activity or transcriptional regulation of inducible heme oxygenase. On the other hand, the inhalation of tobacco smoke can substantially raise the level of carboxyhemoglobin in the blood. Furthermore, methemoglobin is maintained at a constant level. However, excessive production of methemoglobin relative to total methemoglobin reductase activity results in methemoglobin increase. The aim of our study was to investigate the perioperative variations of carboxyhemoglobin and methemoglobin during urologic surgeries, and at the same time to evaluate the changes in methemoglobin as a possible indicator of nitric oxide generation. Our second aim was to evaluate the effect of preoxygenation on the level of carboxyhemoglobin and methemoglobin and the influence of blood transfusion on their changes. The study included 30 patients scheduled for urologic surgery under general endotracheal anesthesia, aged 18-60 years without any history of respiratory disease, divided into two groups. The study group comprised patients who were smoking cigarettes or tobacco pipe, while the control group included non-smokers. In both groups carboxyhemoglobin (COHb) and methemoglobin (MetHb) levels were determined preoperatively, after preoxygenation, and postoperatively. COHb levels were decreased postoperatively in both groups. The average values of COHb between the two groups were statistically significantly different (p=0.00). MetHb levels increased postoperatively in the group of smokers and decreased in the group of non-smokers. There were no statistically significant differences in the average postoperative MetHb levels between the two groups. Changes in carboxyhemoglobin and methemoglobin concentrations in arterial blood occur during urologic surgery, although these amplitudes are small when compared with carbon monoxide intoxication and methemoglobinemia. It is likely that organ perfusion and functions are affected by these monoxide gas mediators during urologic surgery.

BAHA implantation surgery in a pediatric population is usually done in two-stage surgeries. This study aims to evaluate the safety and possible superiority of the one-stage over the two-stage BAHA implantation and which one would be the best standard of care for our pediatric patients. A retrospective chart review of 55 patients operated in our tertiary care institutions between 2005 and 2010 was conducted. The actual tendency in our institutions, applied at the time of the study, is to perform a one-stage surgery for all operated patients (pediatric and adult), except for patients undergoing translabyrinthine surgeries for cerebellopontine tumor excision. These patients indeed had a two-stage insertion. 26 patients underwent one-stage surgery (group I) while 29 patients had a two-stage (group II) BAHA insertion. A period of 4 months was allowed for osseointegration before BAHA processor fitting. As for the safety assessment of the one-stage surgery, we compared both groups regarding the incidence and severity (minor, moderate and major) of encountered complications, as well as the operating time and follow-up. The operating time of the two-stage surgery includes the time of the first and of the second stage. The mean age at surgery was 8.5 years old for the group I and 50 years old for the group II patients. There was no difference in the incidence of minor (p=0.12), moderate (p=0.41) nor severe (p=0.68) complications between groups I and II. Two cases of traumatic extrusion were noted in the group I. Furthermore, the one-stage BAHA implantation requests a significantly lower operating time (mean: 54 [32-100] min) than the two-stage surgery (mean: 79 [63-148] min) (p=0.012). All pediatric cases of BAHA insertion were performed in a one day surgery. The mean postoperative follow-up was 114 and 96 weeks for groups I and II respectively (p=0.058). One-stage BAHA insertion surgery in the pediatric population is a reliable, safe and efficient therapeutic option that allows a good result in a significantly lower operating time compared to the two-stage insertion and is achieved in a one day surgery. It could therefore be considered as a standard of care for pediatric patients. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

OBJECTIVE The aim of this study was to analyze the outcomes of transsphenoidal surgery (TSS) in a single-center clinical series of pediatric craniopharyngioma patients treated with gross-total resection (GTR). METHODS The authors retrospectively reviewed the surgical outcomes for 65 consecutive patients with childhood craniopharyngiomas (28 girls and 37 boys, mean age 9.6 years) treated with TSS (45 primary and 20 repeat surgeries) between 1990 and 2015. Tumors were classified as subdiaphragmatic or supradiaphragmatic. Demographic and clinical characteristics, including extent of resection, complications, incidence of recurrence, pre- and postoperative visual disturbance, pituitary function, and incidence of diabetes insipidus (DI), as well as new-onset obesity, were analyzed and compared between the primary surgery and repeat surgery groups. RESULTS Of the 45 patients in the primary surgery group, 26 (58%) had subdiaphragmatic tumors and 19 had supradiaphragmatic tumors. Of the 20 patients in the repeat surgery group, 9 (45%) had subdiaphragmatic tumors and 11 had supradiaphragmatic tumors. The only statistically significant difference between the 2 surgical groups was in tumor size; tumors were larger (mean maximum diameter 30 mm) in the primary surgery group than in the repeat surgery group (25 mm) (p = 0.008). GTR was accomplished in 59 (91%) of the 65 cases; the GTR rate was higher in the primary surgery group than in the repeat surgery group (98% vs 75%, p = 0.009). Among the patients who underwent GTR, 12% experienced tumor recurrence, with a median follow-up of 7.8 years, and recurrence tended to occur less frequently in primary than in repeat surgery patients (7% vs 27%, p = 0.06). Of the 45 primary surgery patients, 80% had deteriorated pituitary function and 83% developed DI, whereas 100% of the repeat surgery patients developed these conditions. Among patients with preoperative visual disturbance, vision improved in 62% but worsened in 11%. Visual improvement was more frequent in primary than in repeat surgery patients (71% vs 47%, p < 0.001), whereas visual deterioration was less frequent following primary surgery than repeat surgery (4% vs 24%, p = 0.04). Among the 57 patients without preoperative obesity, new-onset postoperative obesity was found in 9% of primary surgery patients and 21% of repeat surgery patients (p = 0.34) despite aggressive resection, suggesting that hypothalamic dysfunction was rarely associated with GTR by TSS in this series. However, obesity was found in 25% of the repeat surgery patients preoperatively due to prior transcranial surgery. Although there were no perioperative deaths, there were complications in 12 cases (18%) (6 cases of CSF leaks, 3 cases of meningitis, 2 cases of transient memory disturbance, and 1 case of hydrocephalus). Postoperative CSF leakage appeared to be more common in repeat than in primary surgery patients (20% vs 4.4%, p = 0.2). CONCLUSIONS The results of TSS for pediatric craniopharyngioma in this case series suggest that GTR should be the goal for the first surgical attempt. GTR should be achievable without serious complications, although most patients require postoperative hormonal replacement. When GTR is not possible or tumor recurrence occurs after GTR, radiosurgery is recommended to prevent tumor regrowth or progression.

The aim of this study was to evaluate the chronological changes in the amount of drainage fluid after thyroidectomy, and to establish standard indications for the drain to be removed. We examined a cohort of 249 patients undergoing thyroid surgery. The patients were divided into four groups: a Graves' group, a non-dissection group, a central-dissection group and a lateral-dissection group. The amount of drainage was measured every 6 h, and the drain was removed postoperatively when the drainage decreased in amount and contained serous fluid after a meal. In all four groups, the most drainage occurred in the first 6 h after surgery. The total amount of drainage from the operation to the time of drain removal was significantly higher in Graves' group and in the lateral-dissection group than in the other two groups. The median wound drainage significantly decreased from 12 to 18 h after surgery in all four groups. In the lateral-dissection group, the wound drainage significantly decreased again in the first 24-30 h. The findings of this study suggest that drains can be removed postoperatively if the drainage was less than 15 mL during a 6-h period and contain serous fluid.

We developed laparoscopic-assisted rectus sheath block (LRSB) as a novel technique and report on its safety and effectiveness. Patients were randomly enrolled to an LRSB or control group (n=19 each). In the LRSB group, after the umbilical wound was closed, local anesthetic was injected transcutaneous at each of 4 sites (3 cm above and below the umbilicus bilaterally) with 10 mL of 0.25% levobupivacaine, laparoscopically. The control group received conventional postoperative pain management. The primary endpoint was visual analogue scale (VAS) pain score at the end of surgery. Secondary endpoints were VAS and Prince Henry pain scale after surgery, number of administrations of analgesics, and side effects of anesthesia. No significant differences in background were seen between groups. VAS at the end of surgery was significantly lower in the LRSB group than in controls (P<0.01). VAS and Prince Henry pain scale were significantly lower in the LRSB group from soon after surgery to postoperative day 2. No complications related to LRSB were encountered. LRSB was particularly effective at the end of surgery and pain scores were significantly lower in the LRSB group long after surgery. Our study shows LRSB is effective and safe for laparoscopic abdominal surgery.

The aim of the study was to compare the effects of peritonsillar infiltration of tramadol before and after the surgery on post-tonsillectomy pain. In this double-blinded clinical trial study, 80 children aged 5-12 years old with ASA (American Society of Anesthesiologists) class I or II undergoing tonsillectomy involved. In group A (n = 40), after anesthesia induction and before starting the surgery, tramadol 2 mg/kg diluted in normal saline up to 2 cc total volume was injected into the tensile bed by the anesthesiologist using a 25 gauge needle. Surgery began 3 min later and the tonsils were removed using the sharp dissection method. In children of group B (n = 40), anesthesia induction was performed. When surgery was completed, tramadol 2 mg/kg diluted in normal saline up to 2 cc total volume was injected at the site of removing each tonsil using a 25 gauge needle by the anesthesiologist. Using the CHEOPS (Children's Hospital of Eastern Ontario Pain Scale) Scale, pain recorded at different times. Patient sedation was recorded using the RAMSAY Sedation Scale. All the data were analyzed using SPSS 17 statistical software. Two groups significantly felt different pain intensities at different times following the surgery. At the three times, the mean sedation score in the group receiving tramadol infiltration before surgery was a little higher compared to the other group, but this difference was not significant (p > 0.05). As for the relative frequency of nausea and vomiting, the difference was not significant (p = 0.793). Request for analgesics between the groups was not significant (p = 0.556). The mean time of the first feeding after the surgery was not significant between the groups (p = 0.062). Surgical duration was almost the same for both groups (p > 0.05). Systolic blood pressures (before surgery, before extubation, and after extubation) were statistically the same in both groups (p < 0.05). Furthermore, systolic blood pressures 10, 15, and 30 min after entry into the recovery room were the same in both groups. We concluded that peritonsillar infiltration of tramadol before surgery controlled postoperative pain better from 8 h after the surgery to hospital discharge (late effect), but that local infiltration of tramadol after surgery controlled postoperative pain better up to 2 h after the operation (early effect).

To compare the early psychological changes of cleft lip and palate (CLP) and noncleft patients after maxillofacial corrective surgery, including maxillary distraction osteogenesis and conventional orthognathic surgery. Nine CLP patients were compared with a group of 9 non-CLP patients having similar dentofacial deformities in a prospective longitudinal cohort study. Five of the CLP patients underwent maxillary distraction osteogenesis and 4 underwent conventional orthognathic surgery. A control group of 9 noncleft patients received conventional orthognathic surgery. All patients completed a set of questionnaires to enable their psychological profile to be assessed. The data were collected immediately before surgery (T1), and at 3 weeks (T2) and 12 weeks (T3) after surgery. The CLP patients treated with distraction osteogenesis were happier, but had a higher level of social anxiety and distress than the CLP patients receiving conventional orthognathic surgery. On the other hand, the CLP patients overall were happier, with lower social anxiety and distress, than the noncleft control group. The CLP patients showed a higher level of parental self-esteem than the noncleft patients. This preliminary study shows that CLP patients were generally happier, and had a higher level of parental support, than normal patients suffering from dentofacial deformities. Maxillary distraction osteogenesis seemed to induce a higher level of anxiety and distress in CLP patients than conventional orthognathic surgery in both cleft and noncleft patients.

Bariatric surgery is known as one of the most effective treatments for sustainable weight loss; however, it may be associated with some complications. This study was designed to examine the effects of probiotic supplementation on some morbidities related to this surgery. This was a placebo-controlled, double-blind, randomized clinical trial on morbid obese patients referred for One Anastomosis Gastric Bypass- Mini Gastric Bypass (OAGB-MGB) surgery to a tertiary referral center. Patients were assigned to receive a probiotic supplement (Familact®) or placebo from 4 weeks prior to surgery to 12 weeks after surgery. Anthropometric, biochemical, and inflammatory indices were evaluated at the beginning and the end of the study. At the end of study, significant improvements in some serum inflammatory markers, vitamin D status, and anthropometric measurements were observed (p < 0.05), which were significantly more in probiotic group rather than placebo group (p < 0.05). Moreover, significant improvements in glycemic indices and lipid profile were observed in both groups; however, these changes were not significantly different between the groups. There was no significant difference in serum levels of vitamin B 12 , folate, and homocysteine between groups at week 16 of the study. Our results indicate that probiotic supplementation promotes inflammatory markers, body weight loss, and status of vitamin D in patients undergoing OAGB-MGB bypass. Whether these findings will sustain in longer treatment duration remained to be elucidated in future studies. This study has been registered at Clinicaltrial.gov with registration number NCT02708589.

The caudal epidural block is one of the most commonly used regional anesthetic techniques in children. Administration of morphine via caudal injection enables analgesia, even for upper abdominal surgery. The thoracic paravertebral block has also been successfully used to treat perioperative pain during upper abdominal procedures in pediatric patients. In the current study, we compared the two regional techniques for upper abdominal surgery in infants to determine whether one of them was preferable to the other. Consecutive patients under 12 months of age who underwent upper abdominal surgery were retrospectively divided according to the chosen postoperative analgesia: Group C, caudal ropivacaine-morphine; Group P, paravertebral catheter. We analyzed the following outcomes: requirement for additional analgesics, pain scores, need for mechanical ventilation and oxygen dosage, postoperative blood pressure and heart rate, time to pass first stool, time until first full meal, and complications. Twenty-one consecutive patients were included: 10 in Group C and 11 in Group P. Median age at surgery was 80 (47.5-270.0) and 84.5 (34.3-287.5) days, respectively. No difference was found between the two groups in requirement for additional analgesics at 24 h after surgery (median 1 in Group C vs 1 in Group P, P = 0.288, 95% CI: -2 to 1). BOPS pain scores were only lower in Group P when compared to Group C at 24 h after surgery (median 1 vs 2, P = 0.041, 95% CI: -2 to 0). None of the patients had perioperative complications. In this small series, there was no significant difference between caudal ropivacaine-morphine and paravertebral catheter for postoperative care in infants undergoing upper abdominal surgery. Further prospective studies are needed to compare the efficacy and incidence of complications of caudal block and paravertebral catheter for postoperative analgesia. © 2017 John Wiley & Sons Ltd.

Previous studies have shown that laparoscopic colorectal cancer surgery is highly safe and effective compared to laparotomy. However, whether laparoscopic colorectal cancer surgery can be safely performed in patients with severe comorbidities remains unclear. The aim of this study was to evaluate the safety of laparoscopic colorectal cancer surgery in patients with severe comorbidities. A total of 82 consecutive patients with colorectal cancer who underwent laparoscopic surgery were retrospectively divided into two groups according to whether they had severe comorbidity (50 patients) or non-severe comorbidity (32 patients). An age-adjusted Charlson comorbidity index of ≥6 was defined as severe comorbidity. Operative time, blood loss, and rate of conversion to laparotomy did not differ between the groups. Postoperative complications and the length of the postoperative hospital stay also did not differ significantly between the groups. Laparoscopic colorectal cancer surgery is feasible and safe, even in patients with severe comorbidities. Copyright© 2018, International Institute of Anticancer Research (Dr. George J.

Management of postoperative pain is a common problem in endoscopic sinus surgery. The objective of this study is the evaluation of pregabalin and acetaminophen effects on the management of postoperative pain in patients with nasal polyposis undergoing functional endoscopic sinus surgery (FESS). In this clinical trial, double-blinded study, 70 patients with nasal polyposis who have indication of FESS were enrolled to this study. After operation, patients were divided randomly into pregabalin and acetaminophen therapy groups. The pregabalin group (n = 35) was treated under pregabalin 50 mg TDS and the acetaminophen group (n = 35) was treated under tablet acetaminophen 500 mg/6 h. Each group was administered for 3 d. The visual analogue scale (VAS) was measured in onset, 12, 24, 48 and 72 h after surgery. All data were entered into SPSS software (SPSS Inc., Chicago, IL) and appropriate statistical tests were assessed to every relation. In this study, there was no significant difference between two groups according to VAS in onset (p = .37); however, VAS in 12, 24, 48 and 72 h after operation was significantly lower in the pregabalin group compared with the acetaminophen group (p < .0001, for every four). Also in the pregabalin group, adverse effects were significantly lower than the acetaminophen group (p < .03). Pregabalin has more effect, safely and usefully than acetaminophen on the management of postoperative pain in the patients with nasal polyposis undergoing functional endoscopic sinus surgery.

In recent years, Da Vinci robot system applied in the treatment of intrathoracic surgery mediastinal diseases become more mature. The aim of this study is to summarize the clinical data about mediastinal lesions of General Hospital of Shenyang Military Region in the past 4 years, then to analyze the treatment effect and promising applications of da Vinci robot system in the surgical treatment of mediastinal lesions. 203 cases of mediastinal lesions were collected from General Hospital of Shenyang Military Region between 2010 and 2013. These patients were divided into two groups da Vinci and video-assisted thoracoscopic surgery (VATS) according to the selection of the treatments. The time in surgery, intraoperative blood loss, postoperative drainage amount within three days after surgery, the period of bearing drainage tubes, hospital stays and hospitalization expense were then compared. All patients were successfully operated, the postoperative recovery is good and there is no perioperative death. The different of the time in surgery between two groups is Robots group 82 (20-320) min and thoracoscopic group 89 (35-360) min (P>0.05). The intraoperative blood loss between two groups is robot group 10 (1-100) mL and thoracoscopic group 50 (3-1,500) mL. The postoperative drainage amount within three days after surgery between two groups is robot group 215 (0-2,220) mL and thoracoscopic group 350 (50-1,810) mL. The period of bearing drainage tubes after surgery between two groups is robot group 3 (0-10) d and thoracoscopic group: 5 (1-18) d. The difference of hospital stays between two groups is robot group 7 (2-15) d and thoracoscopic group 9 (2-50) d. The hospitalization expense between two groups is robot group (18,983.6±4,461.2) RMB and thoracoscopic group (9,351.9±2,076.3) RMB (All P<0.001). The da Vinci robot system is safe and efficient in the treatment of mediastinal lesions compared with video-assisted thoracoscopic approach, even though its expense is higher.

Bariatric surgery is a well-documented treatment for obesity, but there are uncertainties about the degree to which such surgery is associated with health care cost reductions that are sustained over time. To provide a comprehensive, multiyear analysis of health care costs by type of procedure within a large cohort of privately insured persons who underwent bariatric surgery compared with a matched nonsurgical cohort. Longitudinal analysis of 2002-2008 claims data comparing a bariatric surgery cohort with a matched nonsurgical cohort. Seven BlueCross BlueShield health insurance plans with a total enrollment of more than 18 million persons. A total of 29 820 plan members who underwent bariatric surgery between January 1, 2002, and December 31, 2008, and a 1:1 matched comparison group of persons not undergoing surgery but with diagnoses closely associated with obesity. Standardized costs (overall and by type of care) and adjusted ratios of the surgical group's costs relative to those of the comparison group. Total costs were greater in the bariatric surgery group during the second and third years following surgery but were similar in the later years. However, the bariatric group's prescription and office visit costs were lower and their inpatient costs were higher. Those undergoing laparoscopic surgery had lower costs in the first few years after surgery, but these differences did not persist. Bariatric surgery does not reduce overall health care costs in the long term. Also, there is no evidence that any one type of surgery is more likely to reduce long-term health care costs. To assess the value of bariatric surgery, future studies should focus on the potential benefit of improved health and well-being of persons undergoing the procedure rather than on cost savings.

To study the value of indoleamine 2,3-dioxygenase (IDO) in the early diagnosis of systemic inflammatory response syndrome (SIRS) after cardiopulmonary bypass in children with congenital heart disease. A total of 90 children with congenital heart disease who underwent cardiopumonary bypass surgery between May 2012 and January 2016 were enrolled. According to the prsence or absence of SIRS after surgery, they were divided into SIRS group (n=43) and control group (n=47). Peripheral blood samples were collected before surgery, during surgery, and after surgery. Serum levels of IDO, C-reactive protein (CRP), and interleukin-6 (IL-6) were measured and compared between the two groups. The receiver operating characteristic (ROC) curve was used to evaluate their diagnostic efficiency. Compared with the control group, the SIRS group had higher serum CRP levels at 72 hours after surgery, higher IL-6 levels during surgery and at 72 hours after surgery, and higher IDO levels at 24 and 72 hours after surgery. IDO had a certain value in the diagnosis of SIRS at 24 hours after surgery with an area under the ROC curve (AUC) of 0.793, a specificity of 100%, and a sensitivity of 58.14%. CRP, IL-6, and IDO had a certain value in the diagnosis of SIRS at 72 hours after surgery. IDO had the highest diagnostic efficiency with an AUC of 0.927, a specificity of 95.74%, and a sensitivity of 76.74% at 72 hours after surgery. IL-6, CRP, and IDO have a certain value in the diagnosis of SIRS after surgery for congenital heart disease, and IDO has a higher diagnostic efficiency. IDO can predict the development of SIRS in children after surgery for congenital heart disease earlier.

The incidence of gallstones and gallbladder sludge is known to be higher in patients after gastrectomy than in general population. This higher incidence is probably related to surgical dissection of the vagus nerve branches and the anatomical gastrointestinal reconstruction. Therefore, some surgeons perform routine concomitant cholecystectomy during standard surgery for gastric malignancies. However, not all the patients who are diagnosed to have cholelithiasis after gastric cancer surgery will develop symptoms or require additional surgical treatments and a standard laparoscopic cholecystectomy is feasible even in those patients who underwent previous gastric surgery. At the present, no randomized study has been published and the decision of gallbladder management is left to each surgeon preference. The study is a randomized controlled investigation. The study will be performed in the General and Oncologic Surgery, Department of Oncology-Azienda Ospedaliero-Universitaria Careggi-Florence-Italy, a large teaching institution, with the participation of all surgeons who accept to be involved in, together with other Italian Surgical Centers, on behalf of the GIRCG (Italian Research Group for Gastric Cancer).The patients will be randomized into two groups: in the first group the patient will be submitted to prophylactic cholecystectomy during standard surgery for curable gastric cancer (subtotal or total gastrectomy), while in the second group he/she will be submitted to standard gastric surgery only.

Epilepsy Surgery: An Evidence Summary

PubMed Central

2012-01-01

Background The Medical Advisory Secretariat, the predecessor of Health Quality Ontario, published an evidence-based analysis on functional brain imaging. This analysis highlighted the low uptake of epilepsy surgery in Ontario and internationally. Objective The objective of this analysis was to review the effectiveness of epilepsy surgery at reducing seizure frequency, as well as the safety of epilepsy surgery. Data Sources The literature search included studies published between January 1995 and March 2012. Search terms included epilepsy, surgery, resection, safety, and complications. Review Methods Studies were eligible for inclusion if they included at least 20 patients undergoing surgery; had a comparison group of patients with epilepsy who were not undergoing surgery; and reported follow-up periods of at least 1 year. Outcomes of interest included seizure frequency and complications associated with surgery. Results Six systematic reviews reported pooled seizure-free rates that ranged from 43% to 75%. Two randomized controlled trials compared the effectiveness of epilepsy surgery with no surgery in patients with drug-refractory epilepsy. Both trials reported significant improvements in the seizure frequency in the surgery group compared with the nonsurgery group. Eight retrospective cohort studies reported on the safety of epilepsy surgery. Of the 2,725 patients included in these studies, there were 3 deaths reportedly related to surgery. Other complications included hemiparesis, infection, and visual field defects. The studies had long follow-up periods ranging from a mean of 2 to 7 years. Limitations The most recent randomized controlled trial was stopped early due to slow enrolment rates. Thus results need to be interpreted with caution. Conclusions There is high quality evidence that epilepsy surgery is effective at reducing seizure frequency. Two randomized controlled trials compared surgery to no surgery in patients with drug-refractory epilepsy. Both demonstrated significant reductions in seizure frequency. There are some complications associated with epilepsy surgery. In the published literature identified, we observed a 0.1% mortality rate associated with the surgery. Plain Language Summary About 30% of patients with epilepsy continue to have seizures despite optimal drug treatment. In some of these patients, surgery to control the number of seizures may be an option. Patients are carefully selected based on frequency of seizures, location of seizure in the brain, and type of seizures. There is good evidence to indicate that surgery is an effective and safe option for some patients with drug-refractory epilepsy. PMID:23074427

The aim of the study was to assess the microperimetric consequences of active internal limiting membrane (ILM) peeling during idiopathic epimacular membrane (IEMM) surgery. This retrospective monocentric study included 32 eyes of 31 consecutive patients who underwent IEMM surgery. Internal limiting membrane integrity was assessed by ILM Blue staining after IEMM removal: peeling was spontaneous (Group S) or active (Group A). Preprocedure and postprocedure (1 and 6 months) examinations were performed using visual acuity determination, spectral domain optical coherence tomography and microperimetry. Twenty-two eyes had an "active ILM peeling" and 10 a "spontaneous ILM peeling." Both groups had comparable and significant improvements in visual acuity 6 months after surgery (+1.82 lines [+9 letters] [Group A] and +1.51 lines [+8 letters] [Group S], P < 0.01) associated with a significant reduction in optical coherence tomography central thickness (-99.9 μm [Group A], P < 0.01 and -62.2 μm [Group S], P = 0.05). Six months after surgery, the microperimetry showed more numerous and deeper microscotomas in the Group A than in the Group S (change in the number of microscotomas: 2.09 vs. -0.10, P = 0.06; change in deficit severity score: 13.18 dB vs. -2 dB, P < 0.01 for Group A and S, respectively). The number of microscotomas and also severity were increased in 63.6% of Group A patients and in only 20% of Group S patients. Microscotomas were most frequently located in IEMM and/or ILM areas. Internal limiting membrane peeling has progressively become generalized in IEMM surgery to reduce recurrences. This additional procedure does not change the postoperative visual acuity but increases the development of deeper microscotomas. The real impact on the quality of vision remains unclear. Active ILM peeling in IEMM surgery may be responsible for visual impairment related to its microtraumatic effects.

Due to the importance of pain control after abdominal surgery, several methods such as transversus abdominis plane (TAP) block are used to reduce the pain after surgery. TAP blocks can be performed using various ultrasound-guided approaches. Two important approaches to do this are ultrasound-guided lateral and posterior approaches. This study aimed to compare the two approaches of ultrasound-guided lateral and posterior TAP blocks to control pain after cesarean section. In this double-blind clinical trial study, 76 patients scheduled for elective cesarean section were selected and randomly divided into two groups of 38 and underwent spinal anesthesia. For pain management after the surgery, one group underwent lateral TAP block and the other group underwent posterior TAP block using 20cc of ropivacaine 0.2% on both sides. Pain intensity was evaluated based on Numerical Analog Scale (NAS) at rest and when coughing, 2, 4, 6, 12, 24 and 36 hours after surgery. The pain at rest in the posterior group at all hours post surgery was lower than the lateral group, especially at 6, 12 and 24 hours after the surgery and the difference was statistically significant ( p =0.03, p <0.004, p =0.001). The results of this study show that ultrasound-guided posterior TAP block compared with the lateral TAP block was more effective in pain control after cesarean section.

Wound healing in cardiac surgery has become a major problem due to the impaired risk profile of many patients. The aim of this study was to prove the influence of autologous platelet gel (APG) on wound healing in a special group of high-risk patients undergoing coronary surgery. We performed a prospective, double-blind study in 44 patients with a special risk constellation relating to wound complications (obesity, diabetes, smoker, New York Heart Association (NYHA) III-IV and peripheral vascular disease). The study group was treated with APG, prepared using the Magellan platelet separator, the control group underwent conventional wound treatment. The incidence of major and minor wound complications at the thoracotomy, as well as in the area of saphenous vein harvesting, was not pronounced in either of the groups. Blood loss and pain sensations did not differ significantly either. Stay in the intensive care unit (ICU) and the in-hospital mortality were also comparable. The duration of the entire operation and the time until removing the chest-tubes were prolonged in the study group. Despite promising results in other fields of surgery, APG shows no beneficial effect in high-risk patients undergoing cardiac surgery. Probably, it depends on different types of microcirculation in atherosclerotic patients, which are quite different from those of other surgical areas. This factor may offset the existing beneficial platelet effects which could be observed, for example, in maxillo-facial surgery.

The objective of this study was to evaluate the effects of musical intervention on preoperative anxiety and vital signs in patients undergoing day surgery. Studies and systematic meta-analyses have shown inconclusive results of the efficacy of music in reducing preoperative anxiety. We designed a study to provide additional evidence for its use in preoperative nursing care. Randomised, controlled study. Patients (n = 183) aged 18-65 admitted to our outpatient surgery department were randomly assigned to either the experimental group (music delivered by earphones) or control group (no music) for 20 minutes before surgery. Anxiety, measured by the State-Trait Anxiety Inventory, and vital signs were measured before and after the experimental protocol. A total of 172 patients (60 men and 112 women) with a mean age of 40·90 (SD 11·80) completed the study. The largest number (35·7%) was undergoing elective plastic surgery and 76·7% of the total reported previous experience with surgery. Even though there was only a low-moderate level of anxiety at the beginning of the study, both groups showed reduced anxiety and improved vital signs compared with baseline values; however, the intervention group reported significantly lower anxiety [mean change: -5·83 (SD 0·75) vs. -1·72 (SD 0·65), p < 0·001] on the State-Trait Anxiety Inventory compared with the control group. Patients undergoing day surgery may benefit significantly from musical intervention to reduce preoperative anxiety and improve physiological parameters. Finding multimodal approaches to ease discomfort and anxiety from unfamiliar unit surroundings and perceived risks of morbidity (e.g. disfigurement and long-term sequelae) is necessary to reduce preoperative anxiety and subsequent physiological complications. This is especially true in the day surgery setting, where surgical admission times are often subject to change and patients may have to accommodate on short notice or too long a wait that may provoke anxiety. Our results provide additional evidence that musical intervention may be incorporated into routine nursing care for patients undergoing minor surgery. © 2011 Blackwell Publishing Ltd.

Adenoid and tonsil surgeries in children: how relevant is pre-operative blood grouping and cross-matching?

2013-01-01

As a part of pre-operative evaluation, several otolaryngologists group and cross-match blood routinely for children undergoing adenoid and tonsil surgeries. This practice has generated several debates either in support or against this practice. The aim of this study is to critically evaluate the incidence of post-tonsillectomy (with or without adenoidectomy) bleeding and blood transfusions in otherwise healthy children with adenoid/tonsil pathologies conducted in the University of Port Harcourt Teaching Hospital (UPTH). A descriptive retrospective study of children who underwent adenoid and tonsil surgeries in the Department of Ear, Nose and Throat (ENT) surgery of UPTH from January 2003 to December 2012. Children with family history of bleeding disorders and derangement of clotting profile as well as different co-morbidity like sickle cell disease were excluded from this study. The patients' data were retrieved from the registers of ENT out-patient clinics, theatre registers and patients case notes. Demographic data, indications for surgery, preoperative investigations, complications and management outcomes were recorded and analyzed. Out of 145 children that had adenoid and tonsil surgeries; only 100 met the criteria for this study. The study subjects included 65 males and 35 females (male: female ratio 1.9:1) belonging to 0-16 years age group (mean age: 3.46 ± 2.82 years). The age group of 3-5 years had the highest (n = 40, 40%) number of surgeries. Adenotonsillectomy was the commonest (n = 85, 85%) surgery performed on patients who had obstructive sleep apnea (OSA). The commonest (n = 6, 6%) complication was haemorrhage, and only few (n = 3, 3%) patients had blood transfusion. However, mortality was recorded in some (n = 3, 3%) patients. This study confirms that the incidence of post adenoidectomy/tonsillectomy bleeding in otherwise healthy children is low and rarely requires blood transfusion. We can conclude that routine preoperative blood grouping and cross-matching of blood for all children undergoing elective adenoid and tonsil surgeries seemed irrelevant and not cost effective. However, it could be carried out in only special circumstances.

To evaluate the impact of enhanced recovery after surgery (ERAS) programs on postoperative complications of pancreatic surgery. Computer searches were performed in databases (including PubMed, Cochrane Library and Embase) for randomized controlled trials or case-control studies describing ERAS programs in patients undergoing pancreatic surgery published between January 1995 and August 2017. Two researchers independently evaluated the quality of the studies' extracted data that met the inclusion criteria and performed a meta-analysis using RevMan5.3.5 software. Forest plots, demonstrating the outcomes of the ERAS group vs the control group after pancreatic surgery, and funnel plots were used to evaluate potential publication bias. Twenty case-control studies including 3694 patients, published between January 1995 and August 2017, were selected for the meta-analysis. This study included the ERAS group ( n = 1886) and the control group ( n = 1808), which adopted the traditional perioperative management. Compared to the control group, the ERAS group had lower delayed gastric emptying rates [odds ratio (OR) = 0.58, 95% confidence interval (CI): 0.48-0.72, P < 0.00001], lower postoperative complication rates (OR = 0.57, 95%CI: 0.45-0.72, P < 0.00001), particularly for the mild postoperative complications (Clavien-Dindo I-II) (OR = 0.71, 95%CI: 0.58-0.88, P = 0.002), lower abdominal infection rates (OR = 0.70, 95%CI: 0.54-0.90, P = 0.006), and shorter postoperative length of hospital stay (PLOS) (WMD = -4.45, 95%CI: -5.99 to -2.91, P < 0.00001). However, there were no significant differences in complications, such as, postoperative pancreatic fistulas, moderate to severe complications (Clavien-Dindo III- V), mortality, readmission and unintended reoperation, in both groups. The perioperative implementation of ERAS programs in pancreatic surgery is safe and effective, can decrease postoperative complication rates, and can promote recovery for patients.

Hallux valgus (HV) is associated with poorer performance during gait and balance tasks and is an independent risk factor for falls in older adults. We sought to assess whether corrective HV surgery improves gait and balance. Using a cross-sectional study design, gait and static balance data were obtained from 40 adults: 19 patients with HV only (preoperative group), 10 patients who recently underwent successful HV surgery (postoperative group), and 11 control participants. Assessments were made in the clinic using body-worn sensors. Patients in the preoperative group generally demonstrated poorer static balance control compared with the other two groups. Despite similar age and body mass index, postoperative patients exhibited 29% and 63% less center of mass sway than preoperative patients during double-and single-support balance assessments, respectively (analysis of variance P =.17 and P =.14, respectively [both eyes open condition]). Overall, gait performance was similar among the groups, except for speed during gait initiation, where lower speeds were encountered in the postoperative group compared with the preoperative group (Scheffe P = .049). This study provides supportive evidence regarding the benefits of corrective lower-extremity surgery on certain aspects of balance control. Patients seem to demonstrate early improvements in static balance after corrective HV surgery, whereas gait improvements may require a longer recovery time. Further research using a longitudinal study design and a larger sample size capable of assessing the long-term effects of HV surgical correction on balance and gait is probably warranted.

Trigger finger is a common clinical disorder, characterised by pain and catching as the patient flexes and extends digits because of disproportion between the diameter of flexor tendons and the A1 pulley. The treatment approach may include non-surgical or surgical treatments. Currently there is no consensus about the best surgical treatment approach (open, percutaneous or endoscopic approaches). To evaluate the effectiveness and safety of different methods of surgical treatment for trigger finger (open, percutaneous or endoscopic approaches) in adults at any stage of the disease. We searched CENTRAL, MEDLINE, Embase and LILACS up to August 2017. We included randomised or quasi-randomised controlled trials that assessed adults with trigger finger and compared any type of surgical treatment with each other or with any other non-surgical intervention. The major outcomes were the resolution of trigger finger, pain, hand function, participant-reported treatment success or satisfaction, recurrence of triggering, adverse events and neurovascular injury. Two review authors independently selected the trial reports, extracted the data and assessed the risk of bias. Measures of treatment effect for dichotomous outcomes calculated risk ratios (RRs), and mean differences (MDs) or standardised mean differences (SMD) for continuous outcomes, with 95% confidence intervals (CIs). When possible, the data were pooled into meta-analysis using the random-effects model. GRADE was used to assess the quality of evidence for each outcome. Fourteen trials were included, totalling 1260 participants, with 1361 trigger fingers. The age of participants included in the studies ranged from 16 to 88 years; and the majority of participants were women (approximately 70%). The average duration of symptoms ranged from three to 15 months, and the follow-up after the procedure ranged from eight weeks to 23 months.The studies reported nine types of comparisons: open surgery versus steroid injections (two studies); percutaneous surgery versus steroid injection (five studies); open surgery versus steroid injection plus ultrasound-guided hyaluronic acid injection (one study); percutaneous surgery plus steroid injection versus steroid injection (one study); percutaneous surgery versus open surgery (five studies); endoscopic surgery versus open surgery (one study); and three comparisons of types of incision for open surgery (transverse incision of the skin in the distal palmar crease, transverse incision of the skin about 2-3 mm distally from distal palmar crease, and longitudinal incision of the skin) (one study).Most studies had significant methodological flaws and were considered at high or unclear risk of selection bias, performance bias, detection bias and reporting bias. The primary comparison was open surgery versus steroid injections, because open surgery is the oldest and the most widely used treatment method and considered as standard surgery, whereas steroid injection is the least invasive control treatment method as reported in the studies in this review and is often used as first-line treatment in clinical practice.Compared with steroid injection, there was low-quality evidence that open surgery provides benefits with respect to less triggering recurrence, although it has the disadvantage of being more painful. Evidence was downgraded due to study design flaws and imprecision.Based on two trials (270 participants) from six up to 12 months, 50/130 (or 385 per 1000) individuals had recurrence of trigger finger in the steroid injection group compared with 8/140 (or 65 per 1000; range 35 to 127) in the open surgery group, RR 0.17 (95% CI 0.09 to 0.33), for an absolute risk difference that 29% fewer people had recurrence of symptoms with open surgery (60% fewer to 3% more individuals); relative change translates to improvement of 83% in the open surgery group (67% to 91% better).At one week, 9/49 (184 per 1000) people had pain on the palm of the hand in the steroid injection group compared with 38/56 (or 678 per 1000; ranging from 366 to 1000) in the open surgery group, RR 3.69 (95% CI 1.99 to 6.85), for an absolute risk difference that 49% more had pain with open surgery (33% to 66% more); relative change translates to worsening of 269% (585% to 99% worse) (one trial, 105 participants).Because of very low quality evidence from two trials we are uncertain whether open surgery improve resolution of trigger finger in the follow-up at six to 12 months, when compared with steroid injection (131/140 observed in the open surgery group compared with 80/130 in the control group; RR 1.48, 95% CI 0.79 to 2.76); evidence was downgraded due to study design flaws, inconsistency and imprecision. Low-quality evidence from two trials and few event rates (270 participants) from six up to 12 months of follow-up, we are uncertain whether open surgery increased the risk of adverse events (incidence of infection, tendon injury, flare, cutaneous discomfort and fat necrosis) (18/140 observed in the open surgery group compared with 17/130 in the control group; RR 1.02, 95% CI 0.57 to 1.84) and neurovascular injury (9/140 observed in the open surgery group compared with 4/130 in the control group; RR 2.17, 95% CI 0.7 to 6.77). Twelve participants (8 versus 4) did not complete the follow-up, and it was considered that they did not have a positive outcome in the data analysis. We are uncertain whether open surgery was more effective than steroid injection in improving hand function or participant satisfaction as studies did not report these outcomes. Low-quality evidence indicates that, compared with steroid injection, open surgical treatment in people with trigger finger, may result in a less recurrence rate from six up to 12 months following the treatment, although it increases the incidence of pain during the first follow-up week. We are uncertain about the effect of open surgery with regard to the resolution rate in follow-up at six to 12 months, compared with steroid injections, due high heterogeneity and few events occurred in the trials; we are uncertain too about the risk of adverse events and neurovascular injury because of a few events occurred in the studies. Hand function or participant satisfaction were not reported.

We retrospectively examined the effect of remifentanil on urine output during gynecological laparoscopic surgery under general anesthesia performed from April 2006 to July 2007. Forty six patients undergoing gynecological laparoscopic surgery under general anesthesia were divided into 2 groups. In group C (n=23), anesthesia was performed using sevoflurane and/or propofol with intermittent fentanyl. In group R (n=23), remifentanil was additionally used with the method of group C. Patient's demography was not different between the two groups. Intraoperative conditions were compatible in both groups. In group R, total dose of fentanyl is significantly lower than group C. BP and HR measured at 20 min after pneumoperitoneum were significantly lower in group R. Intraoperative urine output was significantly greater in group R than group C. A decrease in urine output is commonly seen particularly in laparoscopic surgery. Increased stress hormonal responses due to pneumoperitoneum have been explained as one of the causes of this phenomenon. Remifentanil has been reported to maintain urine output as well as to blunt hormonal responses in CABG surgery. Although we did not measure hormonal responses in the present study, increased urine output could be attributed to decreased catecholamine levels by remifentanil.

Semuloparin is a novel ultra-low-molecular-weight heparin under development for venous thromboembolism (VTE) prevention in patients at increased risk, such as surgical and cancer patients. Three Phase III studies compared semuloparin and enoxaparin after major orthopedic surgery: elective knee replacement (SAVE-KNEE), elective hip replacement (SAVE-HIP1) and hip fracture surgery (SAVE-HIP2). All studies were multinational, randomized and double-blind. Semuloparin and enoxaparin were administered for 7-10 days after surgery. Mandatory bilateral venography was to be performed between days 7 and 11. The primary efficacy endpoint was a composite of any deep vein thrombosis, non-fatal pulmonary embolism or all-cause death. Safety outcomes included major bleeding, clinically relevant non-major (CRNM) bleeding, and any clinically relevant bleeding (major bleeding plus CRNM). In total, 1150, 2326 and 1003 patients were randomized in SAVE-KNEE, SAVE-HIP1 and SAVE-HIP2, respectively. In all studies, the incidences of the primary efficacy endpoint were numerically lower in the semuloparin group vs. the enoxaparin group, but the difference was statistically significant only in SAVE-HIP1. In SAVE-HIP1, clinically relevant bleeding and major bleeding were significantly lower in the semuloparin vs. the enoxaparin group. In SAVE-KNEE and SAVE-HIP2, clinically relevant bleeding tended to be higher in the semuloparin group, but rates of major bleeding were similar in the two groups. Other safety parameters were generally similar between treatment groups. Semuloparin was superior to enoxaparin for VTE prevention after hip replacement surgery, but failed to demonstrate superiority after knee replacement surgery and hip fracture surgery. Semuloparin and enoxaparin exhibited generally similar safety profiles. © 2012 International Society on Thrombosis and Haemostasis.

The prompt recognition of complications is essential in reducing morbidity following anti-reflux surgery. Consequently, many centres employ a policy of routine post-operative contrast studies. The study aimed to examine whether routine contrast studies more effectively recognised early post-operative complications following anti-reflux surgery compared with selective use. This was a retrospective analysis of 240 adults who had undergone primary anti-reflux surgery. Selective use of water-soluble contrast swallows was employed for 115 patients (Group 1) while 125 patients (Group 2) had routine studies. 10 (0.9%) patients from Group 1 underwent contrast studies, four (40%) of which were abnormal. Routine studies in Group 2 identified thirty-two abnormalities (27%) however the inter-group difference was not significant (p = 0.32). Only one case from group 2 required immediate re-intervention. This was not statistically significant (p = 0.78). Multivariate analysis found no significant association between selective or routine imaging and re-intervention rates. One patient from group 2 presented three days following discharge with wrap migration requiring reoperation despite a normal post-operative study. Routine use of contrast imaging following anti-reflux and hiatus hernia surgery is not necessary. It does not identify a significantly greater number of post-operative complications in comparison to selective use. Additionally, routine use of contrast studies does not ensure the diagnosis of all complications in the post-operative period. Copyright © 2015 IJS Publishing Group Limited.

Iatrogenic trauma induced by thyroid surgery is the most common etiology of unilateral vocal fold paralysis (UVFP). UVFP after thyroid surgery may lead to profound physical and psychosocial distress. This study comprehensively evaluated UVFP caused by thyroid surgery, and compared the results with those caused by other surgical trauma. Patients with surgery-related UVFP were evaluated using quantitative laryngeal electromyography, videolaryngostroboscopy, voice acoustic analysis, the Voice Outcome Survey, and the Short Form-36 Health Survey quality-of-life questionnaire. Patients with thyroid surgery and other surgeries were compared. A total of 105 patients were recruited, of whom 52 and 53 were assigned to the thyroid surgery and the other surgery group, respectively. Patients in the thyroid surgery group had a higher proportion of external branch of superior laryngeal nerve (eSLN) involvement, longer duration from disease onset to the first laryngeal electromyography examination, lower jitter, higher harmonic-to-noise ratio, and better quality of life compared with the other surgery group. Specifically for patients in the thyroid surgery group, those with eSLN involvement tended to have more pronounced impairment in jitter and shimmer compared with patients without eSLN involvement. UVFP caused by thyroid surgery has a distinct clinical presentation with relatively high involvement in the eSLN, better voice acoustics, longer waiting time before asking for evaluation, and less impact on quality of life. The involvement of eSLN in these patients further impaired their voice. Early referral is suggested for these patients, especially with suspected eSLN injury.

The pain following gynecological laparoscopic surgery is less intense than that following open surgery; however, patients often experience visceral pain after the former surgery. The aim of this study was to determine the effects of preemptive ketamine on visceral pain in patients undergoing gynecological laparoscopic surgery. Ninety patients undergoing gynecological laparoscopic surgery were randomly assigned to one of three groups. Group 1 received placebo. Group 2 was intravenously injected with preincisional saline and local infiltration with 20 mL ropivacaine (4 mg/mL) at the end of surgery. Group 3 was intravenously injected with preincisional ketamine (0.3 mg/kg) and local infiltration with 20 mL ropivacaine (4 mg/mL) at the end of surgery. A standard anesthetic was used for all patients, and meperidine was used for postoperative analgesia. The visual analogue scale (VAS) scores for incisional and visceral pain at 2, 6, 12, and 24 h, cumulative analgesic consumption and time until first analgesic medication request, and adverse effects were recorded postoperatively. The VAS scores of visceral pain in group 3 were significantly lower than those in group 2 and group 1 at 2 h and 6 h postoperatively (P<0.05 and P<0.01, respectively). At 2 h and 6 h, the VAS scores of incisional pain did not differ significantly between groups 2 and 3, but they were significantly lower than those in group 1 (P<0.01). Groups 1 and 2 did not show any differences in visceral pain scores at 2 h and 6 h postoperatively. Moreover, the three groups showed no statistically significant differences in visceral and incisional pain scores at 12 h and 24 h postoperatively. The consumption of analgesics was significantly greater in group 1 than in groups 2 and 3, and the time to first request for analgesics was significantly longer in groups 2 and 3 than in group 1, with no statistically significant difference between groups 2 and 3. However, the three groups showed no significant difference in the incidence of shoulder pain or adverse effects. Preemptive ketamine may reduce visceral pain in patients undergoing gynecological laparoscopic surgery.

The aim of this study was to explore the effect of electroacupuncture (EA) on immune function in patients undergoing supratentorial craniotomy. We also examined whether point specificity in EA was present. The study involved 29 patients undergoing craniotomy. The patients were divided into three groups: a control (C, n=10), an EA (A, n=9) and a sham acupoints group (S, n=10). Blood samples were collected at the following time points: before anesthesia (T0), 4 h after the induction of anesthesia (T1), 1 day post-surgery (T2) and 2 days post-surgery (T3) to determine the levels of tumor necrosis factor-α (TNF-α), interleukin-8 (IL-8), interleukin-10 (IL-10), immunoglobulin M (IgM), IgA and IgG. Data were analyzed using SPSS 13.0 software. When comparing the levels of cytokines following surgery, we observed that the peripheral blood IL-8 levels in groups A and S were increased significantly compared with those of group C at 1 and 2 days after surgery. When comparing immunoglobulin levels after surgery, we established that the peripheral blood IgA levels in group C had decreased significantly compared to those of group A and group S 4 h after induction of anesthesia and 1 day after surgery. However, there was no significant difference between group A and group S. Compared with simple general anesthesia, acupuncture combined with anesthesia partially reduces immune suppression in the perioperative periods under the same conditions as the simple general anesthesia. Point specificity in EA was not present. PMID:24137250

This study aimed to evaluate whether one-shot dilatation technique is as safe in patients with a history of open-stone surgery as it is in patients without previous open-stone surgery. Between January 2007 and February 2015, 82 patients who underwent percutaneous nephrolithotomy (PNL) surgery with one-shot dilation technique who previously had open-stone surgery were retrospectively reviewed and evaluated (Group 1). Another 82 patients were selected randomly among patients who had PNL with one-shot dilation technique, but with no history of open renal surgery (Group 2). Age, gender, type of kidney stone, duration of surgery, radiation exposure time, and whether or not there was any bleeding requiring perioperative and postoperative transfusion were noted for each patient. The stone-free rates, operation and fluoroscopy time, and peroperative and postoperative complication rates were similar in both groups (p>0.05). Our experience indicated that PNL with one-shot dilation technique is a reliable method in patients with a history of open-stone surgery.

The aim of our study was to evaluate, through prospective randomized study, the outcome and the immediate and late complications of the two types of surgery most widely used for degree III-IV haemorrhoids. A total of 122 patients with degree III and IV hemorrhoids were elected for surgical intervention and, randomly, underwent surgery for PPH or THD. We assessed the most common immediate postoperative complications. The patients have been followed for three months with a mean follow-up at 1 month and 3 months after surgery. Parameters taken into consideration were: bleeding, pain at rest and after evacuation, soiling, constipation and tenesmus. Five patients in PPH group (7.9%) had a major postoperative bleeding, whereas no such episode occurred in THD group (P=ns). In percentage terms, VAS score was lower in THD group than in PPH group, although the difference was not statistically significant. Finally parameters values observed, during the follow-up, proved to be lower for THD group compared to PPH group. PPH and THD are two surgical treatments for degree III and IV haemorrhoids with low perioperative complications and good results in the short term. However, our experience shows that better results in terms of pain and fewer postoperative complications are obtained after THD surgery, such surgery is less invasive and more adaptable to the needs of day surgery.

Preoperative oral carbohydrate (CHO) reduces postoperative insulin resistance. In this randomized trial, the effect of CHO on postoperative whole-body protein turnover was studied. Glucose and protein kinetics ([6,6(2)H(2)]D-glucose, [(2)H(5)]phenylalanine, [(2)H(2)]tyrosine and [(2)H(4)]tyrosine) and substrate oxidation (indirect calorimetry) were studied at baseline and during hyperinsulinaemic normoglycaemic clamping before and on the first day after colorectal resection. Fifteen patients were randomized to receive a preoperative beverage with high (125 mg/ml) or low (25 mg/ml) CHO content. Three patients were excluded after the intervention, leaving six patients in each group. After surgery whole-body protein balance did not change in the high oral CHO group, whereas it was more negative in the low oral CHO group after surgery at baseline (P = 0.003) and during insulin stimulation (P = 0.005). Insulin-stimulated endogenous glucose release was similar before and after surgery in the high oral CHO group, but was higher after surgery in the low oral CHO group (P = 0.013) and compared with the high oral CHO group (P = 0.044). Whole-body protein balance and the suppressive effect of insulin on endogenous glucose release are better maintained when patients receive a CHO-rich beverage before surgery.

To compare the effects of ketorolac 0.45% and diclofenac 0.1% on macular thickness and volume after uncomplicated cataract surgery. A total of 76 eyes of 76 patients who underwent uncomplicated cataract surgery were included. Patients were treated with either diclofenac 0.1% (38 eyes) or ketorolac 0.45% (38 eyes) after surgery. The macular thickness and volume were obtained with optical coherence tomography (OCT). Central subfield thickness (CST, OCT 1 mm zone), total foveal thickness (TFT, OCT 3 mm zone), total macular thickness (TMT, OCT 6 mm zone), average macular thickness (AMT) and total macular volume (TMV) were compared between the two study groups. No significant differences between groups were found in macular thickness or volume 1 month after cataract surgery. Two months after surgery, the ketorolac group had significantly lower CST, TFT, TMT and AMT than the diclofenac group (p < 0.05 for all). Additionally, 1 and 2 months after surgery, changes from preoperative values in CST (both p = 0.04), AMT (p = 0.02 and p < 0.01, respectively) and TMV (both p = 0.04) were significantly less in the ketorolac group than in the diclofenac group. Following uncomplicated cataract surgery, topical ketorolac 0.45% was more effective than diclofenac 0.1% in preventing increases in macular thickness and volume. © 2015 Acta Ophthalmologica Scandinavica Foundation.

The aim of this comparative, prospective, randomized, controlled study was to evaluate two different regimens of analgesics: a preoperative intravenous dose of either Tramadol or Ketorolac given 10 min prior to surgery to assess their impact on clinical recovery after third molar surgery. Forty patients requiring surgical extraction of unilateral impacted mandibular third molars similar in position were enrolled in the study. Patients were randomly divided into two groups based on permuting the numbers. Patients in Group 1 and Group 2 were administered either Tramadol 50 mg or Ketorolac 30 mg, intravenously, 10 min prior to surgery. The difference in postoperative pain was assessed by four primary points: pain intensity as measured by a 10 mm visual analogue scale hourly for 12 h, median time to rescue analgesics, number of analgesics consumed and patient's overall 5-point global assessment scale. Throughout the 12 h investigation period, patients treated with Ketorolac reported significantly lower pain intensity scores, significantly longer time to rescue analgesics (Acetaminophen 500 mg) and less intake of postoperative analgesics. In Group 2, 40% of the patient had good overall assessment as compared to Group 1 where only 25% of patients had good overall assessment. The current study shows that pre-emptive use of Inj. Ketorolac 30 mg intravenously can reduce the severity of the postoperative sequelae of asymptomatic impacted mandibular third molar surgery.

To develop and evaluate an individualized fluid therapy in the elderly patients with coronary heart disease undergoing gastrointestinal surgery. In this prospective study, 60 coronary heart disease patients undergoing gastrointestinal surgery were included in the First Affiliated Hospital of Xinjiang Medical University from March 2009 to March 2012. Patients were randomized into the intervention group and the control group with 30 patients in each group. Individualized fluid therapy was used during surgery and postoperative period in the ICU, which was determined based on target controlled fluid therapy according to cardiac index, stroke volume, and stroke volume variation. Traditional fluid therapy was used in the control group in the intraoperative and postoperative period. The two groups were compared in terms of postoperative hemodynamic parameters, total fluid volume, incidence of adverse cardiac events, and recovery of bowel function. Compared with the control group, mean arterial pressure was significantly increased at the commencement of the surgery. The cardiac index was significantly elevated during surgery and at the end of the surgery. Stroke volume was significantly increased after induction of anesthesia, during the surgery, and at the early stay of ICU period(all P<0.05). Serum lactic acid in the intervention group was significantly lower at the end of surgery and during ICU stay than that in the control group (all P<0.05). During surgery and 24-hour stay in ICU, the total fluid volume, crystal usage, and urine were significantly less, while colloidal fluid use was significantly more in the intervention group as compared to the control group(all P<0.05). The perioperative adverse cardiac event rate was 36.7%(11/30) in the intervention group, lower than 56.7%(17/30) in the control group, but the difference was no statistically significance(P>0.05). In the intervention group, defecation time, time to first flatus, resumption of liquid intake, length of ICU stay and hospital stay were significantly less compared with the control group(P<0.05). In the elderly patients with coronary arterial disease undergoing gastrointestinal surgery, individualized fluid therapy can effectively decrease adverse cardiac events, improve postoperative gastrointestinal function, and reduce length of hospital stay.

As new devices come into the market, percutaneous techniques improve and interventionalists become more experienced; percutaneous closure gets more common in preterms. In this study we aimed to compare efficacy and safety of Patent Ductus Arteriosus closure surgically versus transcatheter method in preterms <2kg. Best of our knowledge this study is the first one that compares outcomes of surgery and percutaneous Patent Ductus Arteriosus closure in preterms. Between the dates July 1997 to October 2014 in our center Patent Ductus Arteriosus of 26 patients <2kg were closed percutaneously (Group A) and 31 less than 2kg operated (Group B). Weight of patients in percutaneous Patent Ductus Arteriosus closure group was significantly more than the surgery group. Mean gestational age of the patients in Group A was 30±1.8weeks, in group B was 28.6±3.5weeks. In group A; all cases were closed successfully except 4 cases: device embolization in 2, cardiac tamponade and iatrogenic aortic coarctation were seen. Pneumomediastinum and chylothorax were the major complications of the surgery group. There was no statistically significance between complication and success rates between two groups. Percutaneous Patent Ductus Arteriosus closure is the candidate for taking the place of surgery in preterms. However, it is not applied routinely; can only be done in fully equipped large centers by experienced interventionalists. Copyright © 2017 Elsevier B.V. All rights reserved.

Background Patients scheduled for bariatric surgery (BS) are encouraged to chew slowly in order to optimise the digestion process. The influence of dental status on patients' ability to comply with advice on chewing behaviour is poorly documented. This study aims to compare modifications of chewing function before and after BS in three groups of obese patients differing in dental status. Method and Findings A cohort of 46 obese women provided three groups: FD group: fully dentate (7–10 functional dental units [FU]); PD group: partially dentate (4–6 FU) without partial dentures; DW group: partial and complete denture wearers. Chewing time (CT), number of chewing cycles (CC), and chewing frequency (CF) were measured before and after surgery during mastication of standardised samples of raw carrot, peanuts, banana, apple and jelly. The median particle-size distribution (D50) of the pre-swallowed bolus was also evaluated for peanut and carrot. Before surgery, the PD and DW groups exhibited greater mean CCs and CTs than the FD group (SNK p<0.05) and produced a bolus with higher granulometry (SNK, p<0.05) than the FD group. After surgery, CT and CC increased for all groups and for all foods, but not statistically significant for jelly. The resulting changes in bolus granulometry observed depended on both food and dental status. The granulometry of carrot bolus remained as fine or as coarse in FD and DW groups respectively as it was before surgery while it was significantly decreased in the PD group (Student's test, p<0.001). Conclusions After bariatric surgery, all the obese patients, regardless of dental status modified their chewing kinematics. The effects of this chewing behaviour on bolus granulometry depended on dental status and type of food. Further studies are needed to understand better the impact of dental status on feeding behaviour and nutrition in patients with obesity. PMID:21799822

 To investigate whether bariatric surgery increases the risk of fracture.  Retrospective nested case-control study.  Patients who underwent bariatric surgery in the province of Quebec, Canada, between 2001 and 2014, selected using healthcare administrative databases.  12 676 patients who underwent bariatric surgery, age and sex matched with 38 028 obese and 126 760 non-obese controls.  Incidence and sites of fracture in patients who had undergone bariatric surgery compared with obese and non-obese controls. Fracture risk was also compared before and after surgery (index date) within each group and by type of surgery from 2006 to 2014. Multivariate conditional Poisson regression models were adjusted for fracture history, number of comorbidities, sociomaterial deprivation, and area of residence.  Before surgery, patients undergoing bariatric surgery (9169 (72.3%) women; mean age 42 (SD 11) years) were more likely to fracture (1326; 10.5%) than were obese (3065; 8.1%) or non-obese (8329; 6.6%) controls. A mean of 4.4 years after surgery, bariatric patients were more susceptible to fracture (514; 4.1%) than were obese (1013; 2.7%) and non-obese (3008; 2.4%) controls. Postoperative adjusted fracture risk was higher in the bariatric group than in the obese (relative risk 1.38, 95% confidence interval 1.23 to 1.55) and non-obese (1.44, 1.29 to 1.59) groups. Before surgery, the risk of distal lower limb fracture was higher, upper limb fracture risk was lower, and risk of clinical spine, hip, femur, or pelvic fractures was similar in the bariatric and obese groups compared with the non-obese group. After surgery, risk of distal lower limb fracture decreased (relative risk 0.66, 0.56 to 0.78), whereas risk of upper limb (1.64, 1.40 to 1.93), clinical spine (1.78, 1.08 to 2.93), pelvic, hip, or femur (2.52, 1.78 to 3.59) fractures increased. The increase in risk of fracture reached significance only for biliopancreatic diversion.  Patients undergoing bariatric surgery were more likely to have fractures than were obese or non-obese controls, and this risk remained higher after surgery. Fracture risk was site specific, changing from a pattern associated with obesity to a pattern typical of osteoporosis after surgery. Only biliopancreatic diversion was clearly associated with fracture risk; however, results for Roux-en-Y gastric bypass and sleeve gastrectomy remain inconclusive. Fracture risk assessment and management should be part of bariatric care. Published by the BMJ Publishing Group Limited.

Background Tumors may induce systemic immune dysfunction, which can be aggravated by surgery and anesthesia/analgesia. Data on the effect of flurbiprofen preemptive analgesia on immune dysfunction is limited. The aim of this study was to investigate the effect of flurbiprofen preemptive analgesia on lymphocytes and natural killer (NK) cells in patients undergoing thoracotomy and thoracoscopy radical esophagectomy, and to explore the analgesic methods suitable for tumor patients. Methods This was a randomized controlled pilot study of 89 patients with esophageal cancer treated with surgery at the Henan Cancer Hospital between January 1, 2015 and December 31, 2016. The patients were divided into three groups: group 1, thoracotomy; group 2, thoracoscopy and laparoscopic surgery; and group 3, flurbiprofen, thoracoscopy, and laparoscopic surgery. CD3+, CD19+, NK, CD4+, and CD8+ cells in whole blood were measured by flow cytometry 30 minutes before surgery (T0), at the end of the thoracic section of the procedure (T1), and at the end of the operation (T2). Results There were no significant differences in CD3+, CD19+, CD8+, NK, and CD4+ cells between the three groups or regarding the time points during the procedure (all P > 0.05). Thoracotomy and thoracoscopy surgery resulted in similar immunological outcomes. Conclusion Flurbiprofen ester preemptive analgesia did not suppress the immune function in patients and could be a safe analgesic method for patients with esophageal cancer undergoing surgery.

Hypoalbuminemia may increase the risk of acute kidney injury (AKI). The authors investigated whether the immediate preoperative administration of 20% albumin solution affects the incidence of AKI after off-pump coronary artery bypass surgery. In this prospective, single-center, randomized, parallel-arm double-blind trial, 220 patients with preoperative serum albumin levels less than 4.0 g/dl were administered 100, 200, or 300 ml of 20% human albumin according to the preoperative serum albumin level (3.5 to 3.9, 3.0 to 3.4, or less than 3.0 g/dl, respectively) or with an equal volume of saline before surgery. The primary outcome measure was AKI incidence after surgery. Postoperative AKI was defined by maximal AKI Network criteria based on creatinine changes. Patient characteristics and perioperative data except urine output during surgery were similar between the two groups studied, the albumin group and the control group. Urine output (median [interquartile range]) during surgery was higher in the albumin group (550 ml [315 to 980]) than in the control group (370 ml [230 to 670]; P = 0.006). The incidence of postoperative AKI in the albumin group was lower than that in the control group (14 [13.7%] vs. 26 [25.7%]; P = 0.048). There were no significant between-group differences in severe AKI, including renal replacement therapy, 30-day mortality, and other clinical outcomes. There were no significant adverse events. Administration of 20% exogenous albumin immediately before surgery increases urine output during surgery and reduces the risk of AKI after off-pump coronary artery bypass surgery in patients with a preoperative serum albumin level of less than 4.0 g/dl.

Transanal endoscopic microsurgery (TEM) is used for the resection of large rectal adenomas and well or moderately differentiated T1 carcinomas. Due to difficulty in preoperative staging, final pathology may reveal a carcinoma not suitable for TEM. Although completion total mesorectal excision is considered standard of care in T2 or more invasive carcinomas, this completion surgery is not always performed. The purpose of this article is to evaluate the outcome of patients after TEM-only, when completion surgery would be indicated. In this retrospective multicenter, observational cohort study, outcome after TEM-only (n = 41) and completion surgery (n = 40) following TEM for a pT2-3 rectal adenocarcinoma was compared. Median follow-up was 29 months for the TEM-only group and 31 months for the completion surgery group. Local recurrence rate was 35 and 11% for the TEM-only and completion surgery groups respectively. Distant metastasis occurred in 16% of the patients in both groups. The 3-year overall survival was 63% in the TEM-only group and 91% in the completion surgery group respectively. Three-year disease-specific survival was 91 versus 93% respectively. Although local recurrence after TEM-only for pT2-3 rectal cancer is worse compared to the recurrence that occurs after completion surgery, disease-specific survival is comparable between both groups. The lower unadjusted overall survival in the TEM-only group indicates that TEM-only may be a valid alternative in older and frail patients, especially when high morbidity of completion surgery is taken into consideration. Nevertheless, completion surgery should always be advised when curation is intended. © 2018 The Author(s) Published by S. Karger AG, Basel.

Patients going through surgery being awake often have a sense of anxiety and need support to relax. The aim of this study was to investigate whether looking at pictures of natural scenery could reduce anxiety and pain and increase relaxation and well-being being awake during the elective surgery. This three-arm, randomized intervention study consisted of one group viewing pictures of natural scenery, one group listening to soft instrumental music, and one control group without distraction, all adult patients (n=174). The State Trait Anxiety Inventory short form and a visual analogue scale on well-being were used as well as sedation treatment if necessary. No differences related to anxiety after surgery were found among the three groups. When controlling for the effect of sedative treatment, however, patients without sedation had a lower degree of anxiety postoperatively (p=0.014). Younger patients had a higher degree of anxiety and lower degree of postoperative relaxation and well-being. Viewing pictures of natural scenery while being awake during elective surgery is as relaxing as listening to soft instrumental music. Offering nature scenery pictures for patients to view could be relaxing during the elective surgery.

Background Skin flaps are commonly used in soft-tissue reconstruction; however, necrosis can be a frequent complication. Several systemic and local agents have been used in attempts to improve skin flap survival, but none that can prevent flap necrosis have been identified. Aims This study aims to determine whether the use of systemic Rosmarinus officinalis (R. officinalis) extract can prevent flap necrosis and improve skin flap recovery. Study Design Animal experimentation. Methods Thirty-five Wistar albino rats were divided in five groups. A rectangular random-pattern flaps measuring 8×2 cm was elevated from the back of each rat. Group I was the control group. In Group II, 0.2 ml of R. officinalis oil was given orally 2h before surgery. R. officinalis oil was then applied orally twice a day for a week. In Group III, R. officinalis oil was given orally twice a day for one week before surgery. At the end of the week, 0.2 mL of R. officinalis oil was given orally 2 h before surgery. In Group IV, 0.2 mL of R. officinalis oil was injected subcutaneously 2 h before surgery. After the surgery, 0.2 mL R. officinalis oil was injected subcutaneously twice a day for one week. In Group V, 0.2 mL R. officinalis oil was injected subcutaneously twice a day for one week prior to surgery. At the end of the week, one last 0.2 mL R. officinalis oil injection was administered subcutaneously 2 h before surgery. After the surgery, 0.2 mL R. officinalis oil was injected subcutaneously twice a day for one week. Results The mean percentage of viable surface area was significantly greater (p<0.05) in Groups II, III, IV, and V as compared to Group I. Mean vessel diameter was significantly greater (p<0.05) in Groups II, III, IV, and V as compared to Group I. Conclusion We have determined that, in addition to its anti-inflammatory and anti-oxidant effects, R. officinalis has vasodilatory effects that contribute to increased skin flap survival.

To compare the results of maternal and perinatal pregnancies of obese women after bariatric surgery. A retrospective cross-sectional study was carried out on 63 women who had undergone bariatric surgery and 73 obese women (control). Demographic data, the characteristics of the bariatric surgery, and the maternal and perinatal results were evaluated. The Student's t-test and chi-square test (χ2) were used to compare the groups. The gestational complications of the prevalence of gestational diabetes mellitus, anemia, and preeclampsia were analyzed using simple and multivariate logistical regression and odd ratios (OD) with their respective confidence intervals (CI) of 95%. The average body mass index (BMI) at the 1st prenatal appointment of the control group was 34.6±3.3 kg/m2 and that of the post-surgical group was 26.5±4.2 kg/m2. The Roux-en-Y Gastric Bypass was used in 100% of cases; no complications were observed during or after the surgeries. The average weight loss in patients with a prior bariatric surgery was statistically significant (P=0.000). The average weight at birth of the control group was significantly higher than in the post-bariatric surgery group (P=0.017). The women who had a prior bariatric surgery had a higher chance of anemia (OR=3.5; CI 95%: 1.5-8.3) and a reduced chance of macrosomia (OR=0.2; CI 95%:0.1-0.5), and prematurity (OR=0.3; CI 95%:0.1-0.7). Those women who had been submitted to bariatric surgery presented better maternal and perinatal results when compared to obese women.

After surgery, rodents frequently receive acetaminophen-treated drinking water for pain relief, but the effectiveness of this practice is often questioned. Gel products are now available to facilitate the delivery of oral medication to rodents after surgery. We sought to compare consumption of flavored medicated gel and medicated water after surgery and to determine whether providing supplemental acetaminophen in gel form ensures the ingestion of a therapeutic dose of an analgesic after surgery. Male C57BL/6 mice were allocated into 3 groups after surgery: those that received acetaminophen-treated water and untreated gel (MW group); those that received medicated gel and untreated water (MG group); and those that received acetaminophen in both forms (MWG group). Total water and gel consumption were monitored daily from the day before surgery until 2 d thereafter. Mice in the MG group consumed significantly less gel than water, and consequently, the total acetaminophen dose per mouse in the MG group (49 mg/kg) was significantly less than that of the MWG group (347 mg/kg). Although the dose consumed by mice in the MW group (158 mg/kg) approached the targeted acetaminophen dose of 200 mg/kg, only mice in the MWG group actually achieved the desired dose. The results of this study indicate that flavored acetaminophen-containing gel can be used in combination with medicated water to ensure that rodents ingest the targeted dose of medication.

Current guidelines for the management of patients with specific low back pain pathology suggest non-surgical intervention as first-line treatment, but there is insufficient evidence to make recommendations of the content in the non-surgical intervention. Opinions regarding the dose of non-surgical intervention that should be trialled prior to decision making about surgery intervention vary. The aim of the present study is to investigate if physiotherapy administrated before surgery improves function, pain and health in patients with degenerative lumbar spine disorder scheduled for surgery. The patients are followed over two years. A secondary aim is to study what factors predict short and long term outcomes. This study is a single blinded, 2-arm, randomized controlled trial with follow-up after the completion of pre-surgery intervention as well as 3, 12 and 24 months post-surgery. The study will recruit men and women, 25 to 80 years of age, scheduled for surgery due to; disc herniation, spinal stenosis, spondylolisthesis or degenerative disc disease. A total of 202 patients will be randomly allocated to a pre-surgery physiotherapy intervention or a waiting list group for 9 weeks. The waiting-list group will receive standardized information about surgery, post-surgical rehabilitation and advice to stay active. The pre-surgery physiotherapy group will receive physiotherapy 2 times per week, consisting of a stratified classification treatment, based on assessment findings. One of the following treatments will be selected; a) Specific exercises and mobilization, b) Motor control exercises or c) Traction. The pre-surgery physiotherapy group will also be prescribed a tailor-made general supervised exercise program. The physiotherapist will use a behavioral approach aimed at reducing patient fear avoidance and increasing activity levels. They will also receive standardized information about surgery, post-surgical rehabilitation and advice to stay active. Primary outcome measure is Oswestry Disability Index. Secondary outcome measures are the visual analogue scale for back and leg pain, pain drawing, health related quality of life, Hospital anxiety and depression scale, Fear avoidance beliefs questionnaire, Self-efficacy scale and Work Ability Index. The study findings will help improve the treatment of patients with degenerative lumbar spine disorder scheduled for surgery.

Parecoxib provides analgesia following a variety of surgeries, including minor gastrointestinal procedures. To our knowledge, there is no data on parecoxib following major gastrointestinal surgery. This study assessed the efficacy and opioid-sparing effects of parecoxib following major gastrointestinal surgeries. Patients in this analysis were a subset from a large, randomized, double-blind, placebo-controlled trial of parecoxib following noncardiac surgeries and consisted of those undergoing a variety of major gastrointestinal surgeries via laparotomy. Pain, pain interference with function, supplemental opioid utilization, opioid-related symptoms, and Patient/Physician Global Evaluation of Study Medication were compared between placebo and parecoxib groups in the 2-3 days following surgery. Significantly ( p <0.001) lower pain scores were observed in the parecoxib group (n=111), relative to placebo (n=126), on Day 2 (-33%) and Day 3 (-35%). Pain interference with function scores was also significantly ( p <0.001) lower among patients receiving parecoxib compared with placebo on Day 2 (-29%) and Day 3 (-36%). At 24, 48, and 72 hours, the cumulative amount of supplemental morphine consumed was 45%, 41%, and 40% less in patients receiving parecoxib compared with placebo (all p <0.001). The risk of experiencing ≥1 opioid-related symptoms was also significantly lower with parecoxib than with placebo on Day 2 (relative risk=0.75; p <0.001). Specifically, the risks of fatigue and drowsiness were significantly (both p <0.05) lower in patients receiving parecoxib compared to those receiving placebo. Patient and Physician Global Evaluation of Study Medication scores were significantly better in the parecoxib group than in the placebo group ( p <0.001). This study is the first to demonstrate that multiple-dose parecoxib, initiated upon recovery from anesthesia, provides analgesia and opioid-sparing effects following a variety of major gastrointestinal surgeries employing laparotomy.

Background Arrhythmia occurring during and after surgery is one of the major complications in open-heart surgery. Dexmedetomidine is an intravenous alpha-2 agonist and very specific short-acting drug to protect the various organs against ischemic injuries and blood reflow. However, the effect of dexmedetomidine for preventing intraoperative heart arrhythmias has not been recognized. Objective This study aimed to determine the effect of dexmedetomidine on the incidence rate of heart arrhythmias and anesthetic required in off-pump coronary artery bypass surgery. Methods This randomized clinical trial was conducted on patients who were candidates for off-pump coronary artery bypass referring to Imam Reza Hospital of Mashhad, Iran, from July 2016 through January 2017. The patients were randomly assigned to two groups of intervention (infusion of 0.5 mcg/kg/h dexmedetomidine together with induction followed by infusion of 0.5 mcg/kg/h by the end of the surgery) or control (saline infusion). Mean arterial pressure (MAP) and heart rate (HR) were measured before induction, during surgery operation and ICU admission. Data were analyzed by SPSS version 18 using Chi Square and independent-samples t-test. Results A total of 76 patients with a mean age of 59.8 ± 8.2 years (in two groups of 38) were studied. The two groups had no statistically significant difference in terms of background variables. The MAP and HR values before induction, during surgery and ICU admission were significantly higher in the control group than in the intervention group (p=0.001). Out of the studied arrhythmias, the values of PAC (55.2% vs. 15.7%), PVC (81.5% vs. 21.0%), AF (26.3% vs. 7.8%), VTAC (21.0% vs. 2.6%) were significantly lower in dexmedetomidine group (p=0.001). Conclusion It seems that dexmedetomidine administration during induction and surgery can cause significant reduction in most of the common arrhythmias in off-pump coronary bypass surgery. The use of dexmedetomidine maintains MAP and HR at significantly lower values, and changes compared to the control group as well as reduces the need for anesthetic compounds. Trial Registration The present study has been registered at the Iranian Registry of Clinical Trials (www.IRCT.IR) with a code of IRCT2016072413159N9 before starting the study. Founding This study was fully sponsored by the Research Deputy at Mashhad University of Medical Sciences, Iran (grant number 941413). PMID:29238500

Background: Pain is a common phenomenon after surgery. Cardiac surgeries are no exception and patients generally experience acute pain after these surgeries. Inadequate pain management after cardiac surgery predisposes patients to many complications. Therefore, the aim of this study was to determine the effects of listening to preferred music on pain intensity after open heart surgery. Materials and Methods: This study was a randomized clinical trial (RCT) conducted in open heart intensive care unit (ICU) of a university hospital in Sari, Iran. A total of 60 patients who were scheduled to undergo open heart surgery were randomly allocated in two groups. Patients in the intervention group (n = 30) listened to their preferred music by headphones for 30 minutes, whereas those in the control group (n = 30) did not listen to music. Using a Numerical Rating Scale (NRS), pain intensity was measured among the patients before the intervention, and immediately, 30 minutes and one hour after the intervention. Data was analyzed by Chi-square test, student's t-test and repeated measures analysis of variance (ANOVA). Findings: Mean pain intensity in the intervention group before, immediately after, 30 minutes and one hour after the intervention were 5.8, 3.1, 2.5 and 2.4, respectively. Corresponding numbers in the control group were 4.7, 4.7, 4.8 and 4.9, respectively. Repeated measures ANOVA showed music to significantly reduce pain intensity (p = 0.0001) Conclusions: Music can be effective as a non-pharmacological, inexpensive, non-invasive and side effect free method for pain management after open heart surgery.

Prospective controlled data on the long-term effects of bariatric surgery on disability pension are not available. This study prospectively compare disability pension in surgically and conventionally treated obese men and women. The Swedish obese subjects study started in 1987 and involved 2010 obese patients who had bariatric surgery and 2037 contemporaneously matched obese controls, who received conventional treatment. Outcomes of this report were: (i) incidence of disability pension from study inclusion to 31 December 2006 in all subjects, and, (ii) number of disability pension days over 10 years in a subgroup of individuals (N=2901) followed for at least 10 years where partial pensions were recalculated to full number of days per year. Objective information on granted disability pension was obtained from the Swedish Social Insurance Agency and disability pension follow-up rate was 99.9%. In men, the unadjusted incidence of disability pension did not differ between the surgery and control groups (N=156 in both groups). When adjusting for baseline confounders in men, a reduced risk of disability pension was suggested in the surgery group (hazard ratio 0.79, 95% confidence interval 0.62-1.00; P=0.05). Furthermore, the adjusted average number of disability pension days was lower in the surgery group, 609 versus 734 days (P=0.01). In women, bariatric surgery was not associated with significant effects on incidence or number of days of disability pension. Bariatric surgery may be associated with favourable effects on disability pension for up to 19 years in men whereas neither favourable nor unfavourable effects could be detected in women.

Specialization and high volume are reported to be related to a better outcome after abdominal aortic aneurysm repair. The aim of this study was to compare, in patients undergoing abdominal aortic aneurysm repair, the outcomes of those whose surgery was done by general surgeons with the outcomes of those whose surgery was done by specialist vascular surgeons. All patients undergoing abdominal aortic aneurysm repair at the Basel University Hospital (referral center) from January 1990 to December 2000 were included. Patients with endovascular treatment were excluded. Operations in group A (n = 189), between January 1990 and May 1995, were done by general surgeons. Operations in group B (n = 291), between June 1995 and December 2000, were done by vascular surgeons. In-hospital mortality and local and systemic complications were assessed. In-hospital mortality rates were significantly lower for group B (with specialist surgeons) than for group A, both overall (group B, 11.7%; group A, 21.7%; p = .003) and for emergency interventions (group B, 28.1%; group A, 41.9%; p = .042). The reduction in mortality for elective surgery in group B was not statistically significant (group B, 1.1%; group A, 4.9%; p = .054). There were significantly fewer pulmonary complications in group B compared with group A (p = .000). We conclude that in patients undergoing abdominal aortic aneurysm repair, those whose surgery is done by a specialized team have a significantly better outcome than those whose surgery is done by general surgeons.

To evaluate the protection of urinary function after laparoscopic radical resection with pelvic autonomic nerve preservation (PANP) for rectal cancer. Prospectively 139 patients with middle or low rectal cancer receiving surgery during November 2005 to October 2007 were divided into two groups (L-PANP, n = 63; O-PANP, n = 76). The radicalism and safety of L-PANP surgery were analyzed and the effects upon urinary function between the two groups assessed by follow-ups and urodynamic study. Patients receiving subtypes I and II of L-PANP surgery had less decrease in contraction of bladder than those receiving the same subtype of O-PANP surgery at 10 days post-operation (Z = -2.358, P = 0.018; Z = -2.268, P = 0.033). And no difference was observed in patients receiving subtype III PANP surgery (Z = -1.302, P = 0.237). However, no matter which subtype of PANP surgery, patients of L-PANP group had a better contraction of bladder than those of O-PANP group at 1 month post-operation (P < 0.05). The 1-year survival rate was 98.0% (50/51) in L-PANP group and 96.6% (57/59) in O-PANP group. And no statistical difference was found between them (P = 0.898). Meanwhile, the 1-year relapse rate of pelvic cavity was 3.9% (2/52) in L-PANP group and 5.1% (3/59) in O-PANP group. And no statistical difference was found between them (P = 0.867). As compared with O-PANP surgery, L-PANP surgery shows a superiority in protection of urinary function.

Bariatric surgery with or without diet change has become one of the most effective treatments for obesity. The objective of this study was to observe the effects of vertical sleeve gastrectomy (VSG) and diet change in Sprague-Dawley rats on both body and tissue weights. Eighteen rats were fed with a standard chow diet (SCD) (C group), and 36 rats were fed with a high-fat diet (HFD) (diet-induced obesity (DIO) group). After 8 weeks, the animals underwent VSG, sham surgery or no surgery (NS). After surgery, a third of the rats fed with the HFD changed to the SCD (DIO + C group). Body weight, food and energy intake were recorded daily during the experiment (12 weeks). Food efficiency (%) (FE) was determined from weekly weight gain and weekly kilocalorie consumed measurements. The DIO group had higher and significant weight gain than the C group at the time of surgery (p < 0.001). The major weight loss (WL) was observed in the DIO + C-VSG group, during the 4 weeks after surgery. Adipose tissues in the DIO + C-VSG group were drastically reduced and had a weight similar to those in the C-VSG group. VSG and the diet change combination led to a greater WL, which was maintained during the 4 weeks post-surgery, leading to a normalization of body weight. VSG and diet change also affected most of the tissues, not only adipose, showing a global change in whole body composition.

There has been increasing number of requests for cosmetic rhinoplastic surgery among Iranian people in different age groups in recent years. One risk for people who undergo such plastic operations is the presence of body dysmorphic disorder (BDD), which can complicate the result and decrease the rate of satisfaction from surgery. This study aimed to investigate mental health problems in people seeking rhinoplastic surgery. In this case-control study, the scores of General Health Questionnaire (GHQ) and DCQ (Dysmorphic Concerns Questionnaire) were obtained from 50 individuals who were candidates for rhinoplasty, and the results were compared with a normal control group. The total GHQ score and scores in anxiety, depression, and social dysfunction sub-scales were higher among the study group. This was the same for the DCQ score. However, the scores of somatization sub-scale of GHQ were not significantly different between the two groups. Psychiatric evaluation of candidates for rhinoplasty seems necessary for prevention of unnecessary and repetitive surgical operations.

This study compared long-term speech performance after cochlear implantation (CI) between surgical strategies in patients with chronic otitis media (COM). Thirty patients with available open-set sentence scores measured more than 2 yr postoperatively were included: 17 who received one-stage surgeries (One-stage group), and the other 13 underwent two-stage surgeries (Two-stage group). Preoperative inflammatory status, intraoperative procedures, postoperative outcomes were compared. Among 17 patients in One-stage group, 12 underwent CI accompanied with the eradication of inflammation; CI without eradicating inflammation was performed on 3 patients; 2 underwent CIs via the transcanal approach. Thirteen patients in Two-stage group received the complete eradication of inflammation as first-stage surgery, and CI was performed as second-stage surgery after a mean interval of 8.2 months. Additional control of inflammation was performed in 2 patients at second-stage surgery for cavity problem and cholesteatoma, respectively. There were 2 cases of electrode exposure as postoperative complication in the two-stage group; new electrode arrays were inserted and covered by local flaps. The open-set sentence scores of Two-stage group were not significantly higher than those of One-stage group at 1, 2, 3, and 5 yr postoperatively. Postoperative long-term speech performance is equivalent when either of two surgical strategies is used to treat appropriately selected candidates.

The aim of this study was to evaluate the effectiveness of submucosal application of tramadol, for acute postoperative facial pain, following the extraction of impacted third molar teeth. This prospective, double-blind, randomised placebo-controlled study included 60 ASA I-II patients undergoing impacted third molar surgery under local anaesthesia. Following the surgical procedure, patients were randomly divided into two groups; group T (1 mg/kg tramadol) and group S (2-mL saline). Treatments were applied submucosally after surgery. Pain after extraction was evaluated using a visual analogue scale (VAS) 0.5, 1, 2, 4, 6, 12, 24, and 48 h postoperatively. The time at which the first analgesic drug was taken, the total analgesic dose used, and adverse tissue reactions were also evaluated. In group T, postoperative VAS scores were significantly lower compared to that in group S (p < 0.05). This study demonstrated that post-operative submucosal application of tramadol is an effective method for reducing acute post-operative facial pain after impacted third molar surgery.

The aim of this study was to determine the kind of information patients need preoperatively about postoperative pain (POP) and whether this is affected by previous surgery experience. A descriptive study design using preoperative questionnaires. Questionnaires with fixed questions related to POP and its management were distributed preoperatively to consenting, consecutive surgical patients. Patients were divided into two groups: patients with previous surgery experience (group A) and patients without previous surgery experience (group B). Of the patients who participated in the study, 94.2% wanted information about POP and 77.8% of them believe that they will feel calmer if they get the information they need. The patients' biggest concern relates to pain management issues after discharge. Next, in order of preference is information about the analgesics that they need to take. The patients want to be informed primarily with a personal interview (59.4%). Previous surgery experience has no effect on patients' needs for information. Most of the patients want to be informed about the management of the POP after being discharged. It is remarkable that patients who had previous surgery experience need the same information with those who had no previous surgery. Copyright © 2016 American Society of PeriAnesthesia Nurses.

The optimal regional technique for analgesia and improved quality of recovery after video-assisted thoracic surgery (a procedure associated with considerable postoperative pain) has not been established. The main objective in this study was to compare quality of recovery in patients undergoing serratus plane block (SPB) with either ropivacaine or normal saline on the first postoperative day. Secondary outcomes were analgesic outcomes, including postoperative pain intensity and opioid consumption. Ninety patients undergoing video-assisted thoracic surgery were randomized to receive ultrasound-guided SPB with 0.4 mL/kg of either 0.375% ropivacaine (SPB group) or normal saline (control group) after anesthetic induction. The primary outcome was the 40-item Quality of Recovery (QoR-40) score at 24 hours after surgery. The QoR-40 questionnaire was completed by patients the day before surgery and on postoperative days 1 and 2. Pain scores, opioid consumption, and adverse events were assessed for 2 days postoperatively. Eighty-five patients completed the study: 42 in the SPB group and 43 in the control group. The global QoR-40 scores on both postoperative days 1 and 2 were significantly higher in the SPB group than in the control group (estimated mean difference 8.5, 97.5% confidence interval [CI], 2.1-15.0, and P = .003; 8.5, 97.5% CI, 2.0-15.1, and P = .004, respectively). The overall mean difference between the SPB and control groups was 8.5 (95% CI, 3.3-13.8; P = .002). Pain scores at rest and opioid consumption were significantly lower up to 6 hours after surgery in the SPB group than in the control group. Cumulative opioid consumption was significantly lower up to 24 hours postoperatively in the SPB group. Single-injection SPB with ropivacaine enhanced the quality of recovery for 2 days postoperatively and improved postoperative analgesia during the early postoperative period in patients undergoing video-assisted thoracic surgery.

To investigate the effects of a preoperative pulmonary rehabilitation programme in patients with lung cancer undergoing video-assisted thoracic surgery. Randomized, single-blind controlled trial. Teaching hospital. Patients with suspected or confirmed lung cancer undergoing video-assisted thoracic surgery. Participants were randomized to either a prehabilitation group or a control group. Participants in the prehabilitation group underwent a combination of moderate endurance and resistance training plus breathing exercises three to five times per week. The primary outcome of the study was exercise capacity. Secondary outcomes were muscle strength (Senior Fitness Test), health-related quality of life (Short-Form 36) and the postoperative outcomes. Patients were evaluated at baseline (before randomization), presurgery (only the prehabilitation group), after surgery and three months post-operatively. A total of 40 patients were randomized and 22 finished the study (10 in the prehabilitation group and 12 in the control group). Three patients were lost to follow-up at three months. After the training, there was a statistically significant improvement in exercise tolerance (+397 seconds, p = 0.0001), the physical summary component of the SF-36 (+4.4 points, p = 0.008) and muscle strength ( p < 0.01). There were no significant differences between groups after surgery. However, three months postoperatively, significant differences were found in the mean change of exercise capacity ( p = 0.005), physical summary component ( p = 0.001) and upper and lower body strength ( p = 0.045 and p = 0.002). A pulmonary rehabilitation programme before video-assisted thoracic surgery seems to improve patients' preoperative condition and may prevent functional decline after surgery.

Inadequate perioperative fluid therapy impairs gastrointestinal function. Studies primarily evaluating the impact of goal-directed fluid therapy on primary postoperative ileus are missing. The objective of this study was to determine whether goal-directed fluid therapy reduces the incidence of primary postoperative ileus after laparoscopic colorectal surgery within an Enhanced Recovery After Surgery program. Randomized patient and assessor-blind controlled trial conducted in adult patients undergoing laparoscopic colorectal surgery within an Enhanced Recovery After Surgery program. Patients were assigned randomly to receive intraoperative goal-directed fluid therapy (goal-directed fluid therapy group) or fluid therapy based on traditional principles (control group). Primary postoperative ileus was the primary outcome. One hundred twenty-eight patients were included and analyzed (goal-directed fluid therapy group: n = 64; control group: n = 64). The incidence of primary postoperative ileus was 22% in the goal-directed fluid therapy and 22% in the control group (relative risk, 1; 95% CI, 0.5 to 1.9; P = 1.00). Intraoperatively, patients in the goal-directed fluid therapy group received less intravenous fluids (mainly less crystalloids) but a greater volume of colloids. The increase of stroke volume and cardiac output was more pronounced and sustained in the goal-directed fluid therapy group. Length of hospital stay, 30-day postoperative morbidity, and mortality were not different. Intraoperative goal-directed fluid therapy compared with fluid therapy based on traditional principles does not reduce primary postoperative ileus in patients undergoing laparoscopic colorectal surgery in the context of an Enhanced Recovery After Surgery program. Its previously demonstrated benefits might have been offset by advancements in perioperative care.

The perioperative safety profile of clopidogrel, a potent antiplatelet agent used in the management of cardiovascular disease, is unknown, and there are no evidence-based guidelines recommending for either its interruption or continuation at this time. The aim of this study was to determine whether patients who are maintained on clopidogrel before general surgical procedures are at increased risk of perioperative bleeding complications. Patients receiving clopidogrel at the time of elective general surgery were randomized to either discontinue clopidogrel 1 week before surgery (group A) or continue clopidogrel into surgery (group B). All other antiplatelet and anticoagulant agents were discontinued before surgery. The primary end points were perioperative bleeding requiring intraoperative or postoperative transfusion of blood or blood components and bleeding-related readmission, reoperation, or mortality within 90 days of surgery. The secondary end points were perioperative myocardial infarction or cerebrovascular accidents within 90 days of surgery. Thirty-nine patients were enrolled and underwent 43 general surgical operations. Twenty-one procedures were randomized to group A and 22 to group B. The most commonly performed individual procedures were open inguinal hernia repair (23%), laparoscopic cholecystectomy (21%), open ventral hernia repair (15%), laparoscopic ventral hernia repair (11%), and laparoscopic inguinal hernia repair (9%). No perioperative mortalities, bleeding events requiring blood transfusion, or reoperations occurred. One readmission for intra-abdominal hematoma requiring percutaneous drainage occurred in each group (group A: 4.8% vs group B: 4.5%; P = 1.0). No myocardial infarctions or cerebrovascular accidents were observed or reported. The outcomes from this prospective study suggest that, patients undergoing commonly performed elective general surgical procedures can be safely maintained on clopidogrel without increased perioperative bleeding risk.

Background There is a need for investigating the analgesic method as part of early recovery after surgery tailored for laparoscopic colorectal cancer (LCRC) surgery. In this randomized trial, we aimed to investigate the analgesic efficacy of an inverse ‘v’ shaped bilateral, subfascial ropivacaine continuous infusion in LCRC surgery. Methods Forty two patients undergoing elective LCRC surgery were randomly allocated to one of two groups to receive either 0.5% ropivacaine continuous infusion at the subfascial plane (n = 20, R group) or fentanyl intravenous patient controlled analgesia (IV PCA) (n = 22, F group) for postoperative 72 hours. The primary endpoint was the visual analogue scores (VAS) when coughing at postoperative 24 hours. Secondary end points were the VAS at 1, 6, 48, and 72 hours, time to first flatus, time to first rescue meperidine requirement, rescue meperidine consumption, length of hospital stay, postoperative nausea and vomiting, sedation, hypotension, dizziness, headache, and wound complications. Results The VAS at rest and when coughing were similar between the groups throughout the study. The time to first gas passage and time to first rescue meperidine at ward were significantly shorter in the R group compared to the F group (P = 0.010). Rescue meperidine was administered less in the R group; however, without statistical significance. Other study parameters were not different between the groups. Conclusions Ropivacaine continuous infusion with an inverse ‘v ’ shaped bilateral, subfascial catheter placement showed significantly enhanced bowel recovery and analgesic efficacy was not different from IV PCA in LCRC surgery.

Ebine, Kunio

Prevention of post-transfusion hepatitis is still a problem in cardiovascular surgery. We initiated the cryopreservation of autologous blood for the transfusion in elective cardiovascular surgery since 1981. This study includes 152 surgical cases in which autologous frozen, allogeneic frozen, and/or allogeneic non-frozen blood were used. In the 152 surgical cases, there were 69 cases in which autologous blood only (Group I) was used; 12 cases with autologous and allogeneic frozen blood (Group II); 46 cases with autologous and allgeneic frozen plus allogeneic non-frozen blood (Group III); and 25 cases with allogeneic frozen plus allogeneic non-frozen blood (Group IV). No hepatitis developed in Groups I (0%) and II (0%), but there was positive hepatitis in Groups III (4.3%) and IV (8.0%) . In 357 cases of those who underwent surgery with allogeneic non-frozen whole blood during the same period, the incidence rate of hepatitis was 13.7% (49/357). Patients awaiting elective surgery can store their own blood in the frozen state. Patients who undergo surgery with the cryoautotransfusion will not produce any infections or immunologic reactions as opposed to those who undergo surgery with the allogeneic non-frozen blood.

An International Consultation on Incontinence-Research Society (ICI-RS) Think Tank in 2015 discussed and evaluated the evidence of when stress incontinence surgery should be performed with prolapse surgery and highlighted evidence gaps, with the aim of recommending further clinical and research proposals. A review of the literature assessing randomized studies where women with vaginal prolapse have been randomized to vaginal prolapse surgery with or without continence surgery were evaluated. The different clinical presentations were also evaluated and their impact on outcome was critically reviewed. There are three symptomatic groups of women with vaginal prolapse who are treated. The first group is continent women with vaginal prolapse. The second group has stress urinary incontinence (SUI) and vaginal prolapse. The last group has vaginal prolapse and have been found through testing to have occult SUI. The studies have reported a range of outcomes for each of these groups. There are different outcomes based on the surgical method used to correct the prolapse and also the different continence surgical techniques. There are insufficient studies to allow firm conclusions to be drawn. The economic impact of the different management pathways is also discussed although costs vary according to different national medical funding systems. There is considerable uncertainty about the optimal method of managing women with vaginal prolapse and stress incontinence due to the different surgical techniques available. In particular the group of women with occult SUI are a challenge as the optimal diagnostic method has not yet been defined. © 2017 Wiley Periodicals, Inc.

Morbidly obesity is characterized by physical and psychological comorbidities which are associated with reduced quality of life. Bariatric surgery has been linked to a reduction of psychopathology other than to a reduction of weight and improvement in physical functioning. Aim of the present study was to compare psychological features of two groups of morbidly obese patients, before and after bariatric surgery, assessing social phobia and quality of life. A total of 46 morbidly obese patients were enrolled in the study. Of them, 20 were waiting for bilio-pancreatic diversion (group A), while 26 had already undergone surgical procedure (group B). Psychometric evaluation assessed social phobia, fear for the body-shape and quality of life, using appropriate psychometric tests. The percentage of patients showing social phobia was significantly higher compared to a sample of healthy controls (p=0.004), both in group A (p=0.003) and in group B (p=0.029). No differences in percentage of patients affected by social phobia were found between groups. A significantly higher percentage of patients affected by distress about the body (p<0.0001) was found in group A with respect to group B. A reduction of quality of life was found in both groups. The present study shows a high prevalence of social phobia in a population of morbidly obese patients, both before and after surgery. A general reduction of quality of life was also observed, with a partial improvement after surgery. Future studies are needed to clarify the relationship between social phobia and quality of life in surgically-treated morbidly obese patients. Copyright © 2015 Elsevier B.V. All rights reserved.

Quality-of-life questionnaires have been used to support decision-making in patients with chronic rhinosinusitis in the past decade. The choice of treatment in practice, however, also considers the patient's decision. To assess the long-term quality of life of patients with chronic rhinosinusitis who decided to avoid surgery. This is a prospective longitudinal study with a group of patients with chronic rhinosinusitis, with and without indication for surgery, with application of the questionnaire SNOT-22 in two periods: between 2011 and 2012 and between June and August 2016, via email. Data were collected from 42 patients, of which 13 presented indications for surgery and 29 were not indicated for surgery. The average quality of life score was 42.1 (±16.4) in the group with an indication for surgery and 40.6 (±23.4) in the group without this indication, p=0.84. All the patients were assessed by a single doctor with blinding in relation to the initial score. No differences were detected between the groups. The impact of the chronic rhinosinusitis was reduced even among the patients with the indication for surgery. Both groups scored over 40. This study can help predict the impact of the chronic rhinosinusitis over time and better adjust expectations with non-surgical treatment.

Surgery, as a treatment, is a stressful experience. The anxiety is more severe in open-heart surgery patients due to its risk and complications. The present study aimed to determine the effect of lavender essence on the levels of anxiety and blood cortisol in candidates for open-heart surgery. This was a single-blind clinical trial, a random allocation study with a control group conducted on 90 candidates for open-heart surgery in two groups of study and control. The study and control groups inhaled two drops of lavender and distilled water for 20 min, respectively. Spielberger questionnaire was filled by the patients. A 2 ml blood sample was taken to measure the cortisol level and patients' vital signs were recorded before and after intervention. Data were analyzed by chi-square in the form of mean, SD, and frequency distribution, independent t-test, paired t-test, and analysis of covariance (ANCOVA), with a significance level of P = 0.05 to modify the pre-test scores. Results showed a significant reduction in mean anxiety score from 56.73 (5.67) to 54.73 (5.42) after intervention in the study group, compared to the control group [1.11 (1.17)] (P < 0.001). There was also a higher difference in cortisol level in the study group compared to the control group [1.88 (0.56) vs. 0.42 (0.45)]. ANCOVA test showed that the 10.8% variance in anxiety score and 69.6% decrease in blood cortisol resulted from inhalation of lavender. Results showed the positive effect of lavender essence on anxiety and blood cortisol level among the patients. Aromatherapy with lavender is suggested to be considered as a nursing intervention in clinical settings.

The use of neuromuscular blocking agent (NMBA) during anesthesia may interfere with facial nerve monitoring (FNM) during parotid surgery. Sugammadex has been reported to be an effective and safe reversal of rocuronium-induced neuromuscular block (NMB) during surgery. This study investigated the feasibility and clinical effectiveness of sugammadex for NMB reversal during FNM in Parotid surgery. Fifty patients undergoing parotid surgery were randomized allocated into conventional anesthesia group (Group C, n = 25) and sugammadex group (Group S, n = 25). Group C did not receive any NMBA. Group S received rocuronium 0.6 mg/kg at anesthesia induction and sugammadex 2 mg/kg at skin incision. The intubating condition and influence on FNM evoked EMG results were compared between groups. The intubation condition showed significantly better in group S patients than C group patients (excellent in 96% v.s. 24%). In group S, rapid reverse of NMB was found and the twitch (%) recovered from 0 to >90% within 10 min. Positive and high EMG signals were obtained in all patients at the time point of initial facial nerve stimulation in both groups. There was no significant difference as comparing the EMG amplitudes detected at the time point of initial and final facial nerve stimulation in both groups. Implementation of sugammadex in anesthesia protocol is feasible and reliable for successful FNM during parotid surgery. Copyright © 2017. Published by Elsevier Taiwan.

Perioperative enteral nutrition (EN) enriched with immune-modulating substrates is preferable for patients undergoing major abdominal cancer surgery. In this study, perioperative EN enriched with immune-modulating nutrients such as arginine, glutamine, and omega-3 fatty acids was evaluated for its anti-inflammatory efficacy in patients with gastric adenocarcinoma or gastrointestinal stromal tumor (GIST) receiving curative surgery. This prospective, randomized, double-blind study recruited 34 patients with gastric adenocarcinoma or gastric GIST undergoing elective curative surgery. These patients were randomly assigned to the study group, receiving immune-modulating nutrient-enriched EN, or the control group, receiving standard EN from 3 days before surgery (preoperative day 3) to up to postoperative day 14 or discharge. Laboratory and inflammatory parameters were assessed on preoperative day 3 and postoperative day 14 or at discharge. Adverse events (AEs) and clinical outcomes were documented daily and compared between groups. No significant differences were observed between the two groups in selected laboratory and inflammatory parameters, or in their net change, before and after treatment. AEs and clinical outcomes, including infectious complications, overall complications, time to first bowel action, and length of hospital stay after surgery, were comparable between treatment groups (all P > 0.05). Immune-modulating nutrient-enriched EN had no prominent immunomodulation effect compared with that of standard EN.

Thoracic spinal anesthesia has been used for laparoscopic cholecystectomy and abdominal surgeries, but not in breast surgery. The present study compared this technique with general anesthesia in breast cancer surgeries. Forty patients were enrolled in this comparative study with inclusion criteria of ASA physical status I-III, primary breast cancer without known extension beyond the breast and axillary nodes, scheduled for unilateral mastectomy with axillary dissection. They were randomly divided into two groups. The thoracic spinal group (S) (n = 20) underwent segmental thoracic spinal anesthesia with bupivacaine and fentanyl at T5-T6 interspace, while the other group (n = 20) underwent general anesthesia (G). Intraoperative hemodynamic parameters, intraoperative complications, postoperative discharge time from post-anesthesia care unit (PACU), postoperative pain and analgesic consumption, postoperative adverse effects, and patient satisfaction with the anesthetic techniques were recorded. Intraoperative hypertension (20%) was more frequent in group (G), while hypotension and bradycardia (15%) were more frequent in the segmental thoracic spinal (S) group. Postoperative nausea (30%) and vomiting (40%) during PACU stay were more frequent in the (G) group. Postoperative discharge time from PACU was shorter in the (S) group (124 ± 38 min) than in the (G) group (212 ± 46 min). The quality of postoperative analgesia and analgesic consumption was better in the (S) group. Patient satisfaction was similar in both groups. Segmental thoracic spinal anesthesia has some advantages when compared with general anesthesia and can be considered as a sole anesthetic in breast cancer surgery with axillary lymph node clearance.

Postoperative ileus (POI) is one of the most common complications of gastrointestinal surgery. The present study was performed to evaluate the effects of glutamine administration on POI after gastric surgery in humans. The subjects were 31 patients who underwent partial distal gastrectomy for gastric cancer and who were randomly assigned to one of two groups based on postoperative treatment: the glutamine group (3 g/day) and the control group. Manometric recording was done 12 days after surgery, and plasma glutamine concentrations were measured preoperatively and on postoperative day 12. Motor activities of the duodenum in the glutamine group were significantly greater than those of the control group in the interdigestive state. The incidence of phase III motor activity (interdigestive migrating motor contractions) in the glutamine group was significantly higher than that in the control group (60 versus 19%). The glutamine group showed a significantly smaller decrease of plasma glutamine levels compared with the control group. Glutamine could act as a motility-recovery agent after gastrectomy in humans.

Bariatric surgery consists in duodenal exclusion from the food passage in obese patients with coexistent type 2 diabetes. Nowadays bariatric surgery is considered the most effective method of glycemic index normalization and insulin resistance reduction. Recent results on obese and non-obese rats showed remission of type 2 diabetes symptoms within few days after the surgery. The aim of the present work was to analyze the mechanisms of neuro-hormonal regulation responsible for early normalization of metabolic syndrome after bariatric surgery. In present study the concentration of selected intestinal hormones and adipokines in blood plasma and gastrointestinal tissues were analyzed. Study was conducted on Wistar rats. Animals were divided into three groups (each n=6): control (SH) shame-operated rats; animals in which visceral fat tissue was extracted (LP); and rats in which Scopinaro bariatric surgery was performed (BPD). Immunochemistry analysis of blood plasma showed decrease of insulin concentration in BPD and LP and increase of polypeptide YY (PYY) in BPD group as compared to the control. In duodenal mucosa homogenates the tendency to reduce insulin in LP and BPD group, and increase PYY and visfatin in BPD group was observed. Histometry analysis showed reduction of mucosa thickness in excluded segments of gastrointestinal tract in BPD group as compared to the SH and LP. Concluding, model studies on rats allowed better understanding of mechanisms important for early normalization of glycemic index and insulin resistance reduction in rats.

Little data exist regarding the recurrence of pancreatitis in pediatric patients with gallstone pancreatitis awaiting cholecystectomy. This study evaluates the recurrence rate of pancreatitis after acute gallstone pancreatitis based on the timing of cholecystectomy in pediatric patients. A retrospective chart review of all patients admitted with gallstone pancreatitis from 2007 to 2015 was performed. Children were divided into the following five groups. Group 1 had surgery during the index admission. Group 2 had surgery within 2 wk of discharge. Group 3 had surgery between 2 and 6 wk postdischarge. Group 4 had surgery 6 wk after discharge, and group 5 patients had no surgery. The recurrence rates of pancreatitis were calculated for all groups. Forty-eight patients with gallstone pancreatitis were identified in this study. The 19 patients in group 1 had no recurrence of their pancreatitis. Of the remaining 29 patients, nine (31%) had recurrence of pancreatitis or required readmission for abdominal pain prior to their cholecystectomy. In group 2, two of the eight patients (25%) had recurrent pancreatitis. In group 3, three of eight patients (37.5%) developed recurrent pancreatitis. In group 4, three of five patients (60%), and in group 5, one of eight. No children in group 5 had demonstrable gallstones at presentation, only sludge in their gallbladder. Cholecystectomy during the index admission is associated with no recurrence or readmission for pancreatitis. Therefore, we recommend that cholecystectomy be performed after resolution of an episode of gallstone pancreatitis during index admission. Copyright © 2017 Elsevier Inc. All rights reserved.

Blood transfusions are common in cardiac surgery, but have been associated with increased morbidity and long-term mortality. Efforts to reduce blood product use during cardiac surgery include fluid restriction to minimize hemodilution, and protocols to guide transfusion decisions. INVOS is a modality that monitors brain tissue oxygen saturation, and could be useful in guiding decisions to transfuse. However, the role of INVOS (brain tissue oxygen saturation) as part of an algorithm to direct blood transfusions during cardiac surgery has not been evaluated. This study was conducted to investigate the value of INVOS as part of a protocol for blood transfusions during cardiac surgery. Prospective, randomized, blinded clinical trial, on 150 (75 per group) elective cardiac surgery patients. The study was approved by the Institution Ethics committee and all patients gave written informed consent. Data were initially analyzed based on "intention to treat", but subsequently were also analyzed "per protocol". When protocol was strictly followed ("per protocol analysis"), compared to the control group, significantly fewer patients monitored with INVOS received any blood transfusions (46 of 70 patients in INVOS group vs. 55 of 67 patients in the control group, p = 0.029). Similarly, patients monitored with INVOS received significantly fewer units of red blood cell transfusions intraoperatively (0.20 ± 0.50 vs. 0.52 ± 0.88, p = 0.008) and overall during hospital stay (1.31 ± 1.20 vs. 1.82 ± 1.46, p = 0.024). When data from all patients (including patient with protocol violation) were analyzed together ("intention to treat analysis"), the observed reduction of blood transfusions in the INVOS group was still significant (51 of 75 patients transfused in the INVOS group vs. 63 of 75 patients transfused in the control group, p = 0.021), but the overall number of units transfused per patient did not differ significantly between the groups (1.55 ± 1.97 vs. 1.84 ± 1.41, p = 0.288). Our data suggest that INVOS could be a useful tool as part of an algorithm to guide decisions for blood transfusion in cardiac surgery. Additional data from rigorous, well designed studies are needed to further evaluate the role of INVOS in guiding blood transfusions in cardiac surgery, and circumvent the limitations of this study.

To compare the rates of intraoperative and postoperative complications of robotic surgery and laparoscopy in the surgical treatment of endometrial cancer. Unicentric retrospective study (Canadian Task Force classification II-2). Tertiary teaching hospital. The study was performed from January 2002 to December 2011 and included patients with endometrial cancer who underwent laparoscopic or robotically assisted laparoscopic surgical treatment. Data collected included preoperative data, tumor characteristics, intraoperative data (route of surgery, surgical procedures, and complications), and postoperative data (early and late complications according to the Clavien-Dindo classification, and length of hospital stay). Morbidity was compared between the 2 groups. The study included 146 patients, of whom 106 underwent laparoscopy and 40 underwent robotically assisted surgery. The 2 groups were comparable in terms of demographic and preoperative data. Intraoperative complications occurred in 9.4% of patients who underwent laparoscopy and in none who underwent robotically assisted surgery (p = .06). There was no difference between the 2 groups in terms of postoperative events. Robotically assisted surgery is not associated with a significant difference in intraoperative and postoperative complications, even when there were no intraoperative complications of robotically assisted surgery.

To compare effective phacoemulsification time (EPT) for the removal of brunescent cataracts treated with femtosecond laser-assisted cataract surgery with standard cataract phacoemulsification techniques. Ruhr University Eye Hospital, Bochum, Germany. Comparative prospective case study. The Lens Opacities Classification System III (LOCS III) grading system was used to measure eyes divided into 4 groups having cataract surgery. Groups 1 and 2 contained eyes with LOCS III grade nuclear opalescence (NO) 3 cataracts treated with standard cataract surgery and femtosecond laser-assisted cataract surgery, respectively. Groups 3 and 4 contained brunescent cataracts, LOCS III grades NO5, treated with standard cataract surgery and femtosecond laser-assisted cataract surgery, respectively. There were 240 eyes, with 60 eyes in each group. The EPT in Group 1 ranged from 0.46 to 3.10 (mean 1.38); the EPT in all eyes in Group 2 was 0 (P < .001). The EPT in Groups 3 and 4 was 2.12 to 19.29 (mean 6.85) and 0 to 6.75 (mean 1.35), respectively (P < .001). A comparison between EPT in Groups 1 and 4 showed that EPT in Group 4 was also lower than in Group 1 (P = .013). Groups 4 and 1 were the most statistically similar of all groups compared, suggesting that EPT for a femtosecond laser-treated grade 5 cataract was most similar to that of a standard-treated grade 3 cataract. Femtosecond laser pretreatment for brunescent cataracts allowed for a significant reduction in EPT compared with manual standard phacoemulsification techniques. Drs.

AIM To compare visual performance of wavefront-guided laser in situ keratomileusis (LASIK) with iris-registration (Wg-LASIK group) and conventional LASIK (LASIK group) one year after surgery and analyze the correlation between wavefront aberrations and visual performance. METHODS Eight hundred and fifty-two myopic eyes of 430 patients were enrolled in this prospective study and divided into two groups: Wg-LASIK group (436 eyes) and LASIK group (416 eyes). A Wavescan Wavefront aberrometer was used to analyze Zernike coefficients and the root-mean-square (RMS) of higher order aberrations, and Optec 6500 visual function instrument was used to measure contrast sensitivity (CS) before and 3, 6, 12 months after surgery. RESULTS The mean spherical equivalent (SE) in Wg-LASIK group was significantly better than those in LASIK group one year after surgery (P=0.024). Wg-LASIK eyes showed better CS values than LASIK eyes at all spatial frequencies with and without glare after surgery (P all<0.01). Moreover, the increase of higher RMS (RMSh), coma, RMS3, RMS4, RMS5 in Wg-LASIK group were significantly lower than those in LASIK group 1 year after surgery (P all<0.05). The increase of coma, spherical aberration (SA), RMS3 and RMS4 in Wg-LASIK and coma and RMS3 in LASIK group were negatively correlated with reduction of contrast sensitivity 1 year after surgery. CONCLUSION A significant better visual performance is got in Wg-LASIK group compared with LASIK group 1 year after surgery, and the Wg-LASIK is particularly suitable for eyes with high-magnitude RMSh.

On-pump coronary artery bypass graft (CABG) surgery impairs gas exchange in the early postoperative period. The main object on this study was evaluation of changes in arterial blood gas values in patients underwent on pump CABG surgery receiving different dose of intravenous nitroglycerin (NTG). sixty-seven consecutive patients undergoing elective on-pump CABG randomly enrolled into three groups receiving NTG 50 μg/min (Group N1, n =67), 100 μg/min (Group N2, n = 67), and 150 μg/min (Group N3, n = 67). Arterial blood gas (ABG) tensions were evaluated just before induction of anesthesia, during anesthesia, at the end of warming up period, and 6 h after admission to the intensive care unit. Pao2 and PH had the highest value during surgery in Group N1, Group N2, and Group N3. No significant difference was noted in mean values of Pao2 and PH during surgery between three groups (P > 0.05). There was no significant difference in HCO3 values in different time intervals among three groups (P > 0.05). our results showed that infusing three different dosage of NTG (50, 100, and 150 μg/min) had no significant effect on ABG tensions in patients underwent on-pump CABG surgery.

To assess the decentration and angle of tilt of the intraocular lens (IOL) according to the intravitreal tamponade types used in combined phacoemulsification and vitreoretinal surgery. This prospective and randomized clinical study involved 73 eyes of 69 patients who underwent combined vitreoretinal surgery. Eyes with intravitreal tamponades formed the study group and eyes without intravitreal tamponades formed the control group. The study group was further divided into silicone oil and gas tamponade subgroups. Cross-sectional IOL images were captured using a Pentacam HR (Oculus, Germany) and tilt and decentration were calculated with Adobe Photoshop software (Adobe, San Jose, CA). The mean angle of tilt and decentration at the vertical meridian were significantly higher in both tamponade groups than in the control group (P < 0.05 for all). No significant difference was observed among the groups regarding IOL position parameters at the horizontal meridian (P > 0.05). When comparing the silicone oil and gas tamponade subgroups, no significant differences were noted on the position of IOL at both meridians (P > 0.05 for all). Intravitreal tamponades have an important effect on the position of IOL in combined vitreoretinal surgery. Silicone oil and gas tamponades may induce postoperative tilt and decentration of one-piece acrylic IOLs.

Many studies have shown the benefits of diathermy over scalpel for making skin incisions in terms of post operative pain and post operative analgesics requirement. The objective of the study is to compare the pain following incision by scalpel and diathermy for skin in ENT surgery. We conducted a prospective, randomized study and compared early post operative pain and analgesics requirement in patients undergoing ENT and Head and Neck surgery in Department of ENT at Kathmandu Medical College from September 2016 to August 2017. The statistical analysis was done using MS Excel and SPSS software. Out of 65 participants, 31 were allocated in scalpel group and 30 were allocated in diathermy group. The mean VAS score was significantly greater in scalpel group as compared to diathermy group in post operative 12, 24 and 48 hours (P<0.05). The mean ketorolac requirement was significantly more in scalpel group than in diathermy group in post operative 24 hours. The early post operative pain is less in ENT-Head and Neck surgery patients with skin incision by diathermy as compared to the patients with skin incision by scalpel.

Introduction: The present study examined the favorable attitude of a sample of female university students regarding elective cosmetic surgery, body dysmorphic disorder, self-esteem and body dissatisfaction following a media literacy training intervention. Methods: This study was a quasi-experimental type. The study sample included 140 female university students who were allocated to either the intervention (n=70) or the control group (n=70). Attitude toward cosmetic surgery, body dysmorphic disorder, self-esteem and, body satisfaction was measured in both groups before the intervention and 4 weeks later. Four media literacy training sessions were conducted over 4 weeks for the intervention group. The data was analyzed through analysis of covariance, student’s paired-samples t test, and Pearson correlation. Results: Our findings showed that favorable attitude, body dysmorphic disorder and body dissatisfaction scores were significantly lower (p<0.05) in the intervention group than the control group. Furthermore, self-esteem score increased significantly in the intervention group. Conclusions: Our results underscores the importance of media literacy intervention in decreasing female’s favorable attitude towards elective cosmetic surgery, body dysmorphic disorder and body dissatisfaction as well as increasing self-esteem.

Currently, many scholars are concerned about the treatment of postoperative infection; however, few have completed multivariate analyses to determine factors that contribute to the risk of infection. Therefore, we conducted a multivariate analysis of a retrospectively collected database to analyze the risk factors for acute surgical site infection following lumbar surgery, including fracture fixation, lumbar fusion, and minimally invasive lumbar surgery. We retrospectively reviewed data from patients who underwent lumbar surgery between 2014 and 2016, including lumbar fusion, internal fracture fixation, and minimally invasive surgery in our hospital's spinal surgery unit. Patient demographics, procedures, and wound infection rates were analyzed using descriptive statistics, and risk factors were analyzed using logistic regression analyses. Twenty-six patients (2.81%) experienced acute surgical site infection following lumbar surgery in our study. The patients' mean body mass index, smoking history, operative time, blood loss, draining time, and drainage volume in the acute surgical site infection group were significantly different from those in the non-acute surgical site infection group (p < 0.05). Additionally, diabetes mellitus, chronic obstructive pulmonary disease, osteoporosis, preoperative antibiotics, type of disease, and operative type in the acute surgical site infection group were significantly different than those in the non-acute surgical site infection group (p < 0.05). Using binary logistic regression analyses, body mass index, smoking, diabetes mellitus, osteoporosis, preoperative antibiotics, fracture, operative type, operative time, blood loss, and drainage time were independent predictors of acute surgical site infection following lumbar surgery. In order to reduce the risk of infection following lumbar surgery, patients should be evaluated for the risk factors noted above.

Postoperative pain is less intense after laparoscopic than after open surgery. However, minimally invasive surgery is not a a pain-free procedure. Many trials have been done in adults using intraperitoneal and/or incisional local anesthetic, but similar studies have not yet been reported in the literature in children. The aim of this study was to evaluate the analgesic effect of periportal infiltration and intraperitoneal instillation of ropivacaine in children undergoing laparoscopic surgery. Thirty patients who underwent laparoscopic surgery were randomly allocated to one of three groups. Group A (n = 10) received local infiltration of port sites with 10 mL of ropivacaine. Group B (n = 10) received both an infiltration of port sites with 10 mL of ropivacaine and an intraperitoneal instillation of 10 mL of ropivacaine. Group C did not receive any analgesic treatment. The local anesthetic was always administered at the end of surgery. The degree of postoperative abdominal parietal pain, abdominal visceral pain, and shoulder pain was assessed by using a Wong-Baker pain scale and a Visual Analog Scale (VAS) at 3, 6 12, and 24 hours postoperatively. The following parameters were also evaluated: rescue analgesic treatment, length of hospital stay, and time of return to normal activities. Three hours after operation, patients had low pain scores. Six and 12 hours postoperatively, the abdominal parietal pain was significantly higher (P < 0.0005) in group C than in the other two groups, both treated with an infiltration at the trocar sites; mean intensity of abdominal visceral pain was significantly lower (P < 0.0005) in group B than in groups A and C; the overall incidence of shoulder pain was significantly lower (P < 0.0005) in group B patients than in patients of groups A and C. At 20 hours postoperatively, pain scores were significantly reduced of intensity in all groups. Rescue analgesic treatment was significantly higher in group C, if compared to groups A and B 12 hours after the operation. No statistically significant difference was found in length of hospital stay, but children who received analgesic treatment had a more rapid return to normal activities than untreated patients (P < 0.0005). Our study demonstrates that the combination of local infiltration and intraperitoneal instillation of ropivacaine is more effective for pain relief in children after laparoscopic surgery than the administration of ropivacaine only at the trocar sites.

Adult spinal deformity (ASD) is an important problem to consider in the elderly. Although studies have examined the complications of ASD surgery and have compared functional and radiographic results of primary surgery versus revision, no studies have compared the costs of primary procedures with revisions. We assessed the in-hospital costs of these 2 surgery types in patients with ASD. The PearlDiver Database, a database of Medicare records, was used in this study. Mutually exclusive groups of patients undergoing primary or revision surgery were identified. Patients in each group were queried for age, sex, and comorbidities. Thirty-day readmission rates, 30-day and 90-day complication rates, and postoperative costs of care were assessed with multivariate analysis. For analyses, significance was set at P < 0.001. The average reimbursement of the primary surgery cohort was $57,078 ± $30,767. Reimbursement of revision surgery cohort was $52,999 ± $27,658. The adjusted difference in average costs between the 2 groups is $4773 ± $1069 (P < 0.001). The 30-day and 90-day adjusted difference in cost of care when sustaining any of the major medical complications in primary surgery versus revision surgery was insignificant. Patients undergoing primary and revision corrective procedures for ASD have similar readmission rates, lengths of stays, and complication rates. Our data showed a higher cost of primary surgery compared with revision surgery, although costs of sustaining postoperative complications were similar. This finding supports the decision to perform revision procedures in patients with ASD when indicated because neither outcomes nor costs are a hindrance to correction. Copyright © 2017 Elsevier Inc.

Leptin may be involved in the acute stress response, regulating inflammatory parameters of major importance after cardiopulmonary bypass (CPB) surgery. Critically ill patients demonstrated significant increases in leptin levels in response to stress-related cytokines (tumor necrosis factor, interleukin [IL]-1) and abolishment of the circadian rhythm of leptin secretion. We characterized the pattern of leptin secretion in the acute postoperative period in children undergoing cardiac surgery and compared the changes in leptin levels with concomitantly occurring changes in cortisol levels, IL-8, and clinical parameters. Investigative study. University-affiliated tertiary care hospital. Twenty-nine consecutive patients, aged 6 days to 15 yrs, operated upon for the correction of congenital heart defects were studied. Surgery in 20 patients (group 1) involved conventional CPB techniques, and 9 (group 2) underwent closed-heart surgery. The time courses of leptin, cortisol, and IL-8 levels were determined. Serial blood samples were collected preoperatively, on termination of CPB, and at six time points postoperatively. Plasma was recovered immediately, aliquoted, and frozen at -70 degrees C until use. The leptin levels in group 1 decreased during CPB to 51% of baseline (p <.001), then gradually increased, reaching 120% of baseline levels at 12-18 hrs postoperatively (p <.001), returning to baseline levels at 24 hrs (p <.01). In patients undergoing closed-heart surgery (group 2), leptin levels displayed a pattern resembling the first group: they decreased during surgery to 71% of baseline levels (p =.002) and showed a tendency to return to baseline thereafter. All group 1 patients' cortisol levels increased significantly during the first hour of surgery, then decreased, returning to baseline levels at 18-24 hrs postoperatively. There was a significant negative correlation between leptin and cortisol levels (r = -2.8, p <.01). In group 2, cortisol levels increased during and after surgery, peaking 4 hrs postoperatively and decreasing thereafter. IL-8 levels determined in 15 group 1 patients increased significantly during CPB, peaked at the end of surgery, and then decreased but remained slightly elevated even at 48 hrs postoperatively. There was a significant correlation between cortisol and IL-8 levels (r = 2.55, p <.05). Children with leukocytosis, tachycardia, and hypotension had lower leptin levels and less variation over time as opposed to those with an uncomplicated course. CPB is associated with acute changes in circulating leptin levels. These changes parallel those in cortisol, demonstrating an inverse relationship between leptin and cortisol. Further studies of the prognostic and therapeutic roles of leptin after CPB should be investigated.

Localized macular edema and retinal nerve fiber layer (RNFL) thinning have been reported shortly after laser in situ keratomileusis (LASIK) in adults. However, it is still unclear how LASIK affects the retina of children. This study aimed to investigate the macular retina and RNFL thickness in children with refractive amblyopia who underwent femtosecond laser-assisted LASIK (FS-LASIK). In this study, we included 56 eyes of 32 patients with refractive amblyopia who underwent FS-LASIK in our hospital from January 2012 to December 2016. Foveal (foveal center retinal, parafoveal retinal, and perifoveal), macular inner retinal (superior and inferior), and peripapillary RNFL thicknesses (superior, inferior, temporal, and nasal) were measured using Fourier-domain optical coherence tomography before surgery and 1 day, 3 days, and 1 week after surgery. We divided these patients into three groups based on their refractive error: High myopic group with 22 eyes (equivalent sphere, >6.00 D), mild myopic group with 19 eyes (equivalent sphere, 0-6.00 D), and hyperopic group with 15 eyes (equivalent sphere, >+0.50 D). We compared the macular retina and RNFL thickness before and after LASIK. A paired simple t-test was used for data analysis. One week after surgery, the visual acuity for all 56 eyes of the 32 patients reached their preoperative best-corrected vision. Visual acuity improved two lines or better for 31% of the patients. The residual refractive errors in 89% of the patients were within ±0.5 D. In the high myopic group, the foveal center retinal and parafoveal retinal thicknesses were thicker 1 day and 3 days after surgery than before surgery (t = 2.689, P = 0.012; t = 2.383, P = 0.018, respectively); no significant difference was found 1 week after surgery (P > 0.05). The foveal center retinal and parafoveal retinal thicknesses were greater 1 day after surgery than they were before surgery (P = 0.000 and P = 0.005, respectively) in the mild myopic and hyperopic groups. No significant difference was found 3 days or 1 week after surgery (P > 0.05). In all three groups, no significant difference was found in the macular inner retinal or peripapillary RNFL thickness 1 day, 3 days, or 1 week after surgery (P > 0.05). The foveal center retinal edema after FS-LASIK is mild and reversible in children, that mostly occurred in the high myopic group with no effect on the visual acuity, and is always relieved within 1 week.

An acute infection after arthroscopic shoulder surgery is a rare but serious complication. Previous studies estimating the incidence of infections after arthroscopic surgery have been conducted, but the majority of these had either relatively small study groups or were not specific to shoulder arthroscopic surgery. To investigate the incidence of acute infections after arthroscopic shoulder surgery and compare infection rates by age group, sex, geographic region, and specific procedures. Case series; Level of evidence, 4. A retrospective review of a large insurance company database was performed for all shoulder arthroscopic surgeries performed in the United States between 2004 and 2009 that required additional surgery for infections within 30 days. The data were stratified by sex, age group, and region. Data were also stratified for specific procedures (capsulorrhaphy, treatment for superior labrum anterior-posterior tears, claviculectomy, decompression, and rotator cuff repair) and used to assess the variation in the incidence of infections across different arthroscopic shoulder procedures. Linear regression was used to determine the significance of differences in the data from year to year. χ(2) analysis was used to assess the statistical significance of variations among all groups. Poisson regression analysis with exposure was used to determine significant differences in a pairwise comparison between 2 groups. The total number of arthroscopic shoulder surgeries performed was 165,820, and the number of infections requiring additional surgery was 450, resulting in an overall infection rate of 0.27%. The incidence of infections varied significantly across age groups (P < .001); the infection rate was highest in the ≥60-year age group (0.36%) and lowest in the 10- to 39-year age group (0.18%). The incidence of infections also varied by region (P < .001); the incidence was highest in the South (0.37%) and lowest in the Midwest (0.11%). The incidence of infection treatments was also significantly different between different arthroscopic procedures (P < .01) and was highest for rotator cuff repair (0.29%) and lowest for capsulorrhaphy (0.16%). The incidence did not significantly vary by year or sex. The overall infection rate for all arthroscopic shoulder procedures was 0.27%. The incidence was highest in elderly patients, in the South, and for rotator cuff repair. The incidence was lowest in young patients, in the Midwest, and for capsulorrhaphy. In general, shoulder arthroscopic surgery in this study population had a low rate of reoperation in the acute period.

The purpose of the following study is to evaluate the treatment modalities, clinical status and prognostic factors affecting survival rates in patients with newly diagnosed brain metastasis from non-small cell lung cancer (NSCLC). NSCLC patients with a new diagnosis of one to four brain metastasis evaluated retrospectively for the effects of treatment regimens on local failure-relapse-free survival (LRFS) and overall survival (OS). The relationship between age, gender, performance status, recursive partitioning analysis (RPA) classification, the primary tumor under control, number of metastatic tumors in the brain and total volume of brain metastasis and prognosis is analyzed. Out of a total of 138 (121 male and 17 female) patients, nearly 44.2% received only gamma-knife (GK); 24.6% were received both GK and whole brain radiotherapy (WBRT), 2.9% had GK and surgery, 3.6% received GK, surgery and WBRT, 10.9% had surgery and WBRT and 12.3% received only WBRT for treatment. Median LRFS of surgery plus WBRT group was significantly higher when compared with WBRT group (P<0.0001). The OS was significantly longer for surgery plus WBRT group than the other treatment groups (P=0.037). When median survival of WBRT-only group compared with surgery plus WBRT, it was significantly higher (29.6 months vs. 16.7 months, P=0.006). Median OS of surgery plus WBRT group was significantly higher than GK plus WBRT group (29.6 months vs. 9.3 months, P=0.007). WBRT is still the most effective treatment method following surgery in selected patients according to their age, performance status and spread of the primary disease with NSCLC had limited number brain metastasis. Adding WBRT treatment after surgery significantly improved OS and LRFS.

There is no clear data about the optimum time for chest tube removal after coronary artery bypass surgery. The aim of this study was to assess the impact of the chest tube removal time following coronary artery bypass grafting surgery on the clinical outcome of the patients. An analysis of data from 307 patients was performed. The patients were randomized into two groups: in group 1 (N=107) chest tubes were removed within the first 24 hours after surgery, whereas in group 2 (N=200), chest tubes were removed in the second 24 hours after surgery. Demographics, lactate and pH at the beginning, during and after the operation, creatinine, left ventricular ejection fraction, inotropic drugs administration, length of ICU stay, and mortality data were collected. Respiratory rate and pain level was assessed. In these surgeries, the mean± standard deviation for the aortic clamping time was 49.18±17.59 minutes and cardiopulmonary bypass time was 78.39±25.12 minutes. The amount of heparin consumed by the second group was higher (P <0.001) which could be considered as an important factor in increasing the drainage time after the surgery (P =0.047). The pain level evaluated 24 hours post-operation was lower in the first group, and the difference in the pain level between the 2 groups evaluated 30 hours post-operation was significant (P=0.016). The mean time of intensive care unit stay was longer in the second group but it was not statistically significant. Early extracting of chest tubes after coronary artery bypass graft surgery when there is no significant drainage can lead to pain reduction and consuming oxygen is an effective measure after surgery toward healing; it doesn't increase the risk of creation of plural effusion and pericardial effusion.

This study aims to explore the effects of tranexamic acid on the coagulation indexes of patients undergoing heart valve replacement surgery under the condition of cardiopulmonary bypass (CPB). One hundred patients who conformed to the inclusive criteria were selected and divided into a tranexamic acid group and a non-tranexamic acid group. They all underwent heart valve replacement surgery under CPB. Patients in the tranexamic acid group were intravenously injected with 1 g of tranexamic acid (100 mL) at the time point after anesthesia induction and before skin incision and at the time point after the neutralization of heparin. Patients in the non-tranexamic acid group were given 100 mL of normal saline at corresponding time points, respectively. Then the coagulation indexes of the two groups were analyzed. The activated blood clotting time (ACT) of the two groups was within normal scope before CPB, while four coagulation indexes including prothrombin time (PT), activated partial thromboplastin time (APTT), international normalized ratio (INR), and fibrinogen (FIB) had significant increases after surgery; the PT and INR of the tranexamic acid group had a remarkable decline after surgery. All the findings suggest that the application of tranexamic acid in heart valve replacement surgery under CPB can effectively reduce intraoperative and postoperative blood loss. PMID:27694613

To determine if imaging findings on computed tomography (CT) can predict the need of surgery in patients with idiopathic mesenteric phlebosclerosis (IMP).This retrospective study included 28 patients with IMP. Abdominal CT images were reviewed to determine the extent and severity of mesenteric calcifications and the presence of findings related to colitides. We compared the number of colonic segments with mesenteric venous calcification, a total calcification score, and the rate of colonic wall thickening, pericolic fat stranding, and bowel loop dilatation between patients undergoing surgery (surgery group) and patients without surgery (nonsurgery group). Comparisons were made using the Mann-Whitney U test and Fisher exact test. Receiver operating characteristic analysis was also performed. Inter-reader agreement for the calcification scores was analyzed using kappa statistics.The number of colonic segments with mesenteric venous calcification and the total calcification scores were both significantly higher in the surgery group than the nonsurgery group (4.33 vs 2.96, P = 0.003; and 15.00 vs 8.96, P <0.001). The areas under the receiver operating characteristics to identify patients who need surgery were 0.96 and 0.92, respectively. The prevalence of bowel loop dilatation in the surgery group was also significantly higher than that in the nonsurgery group (16% vs 100%, P = 0.011).Evaluation of the severity and extent of IMP based on the total mesenteric venous calcification score, number of involved colonic segments, and the presence bowel loop dilatation on CT may be useful to indicate the outcomes of conservative treatment and need for surgery.

Quality of voice after immediate recurrent laryngeal nerve (RLN) reconstruction in thyroid cancers has not been thoroughly studied. Thirteen patients with fixed vocal cords (fixed vocal cord group) and 8 patients with intact or impaired mobile vocal cords (mobile vocal cord group) who had immediate RLN reconstruction simultaneously with total thyroidectomy, and patients who had arytenoid adduction and thyroplasty for vocal cord paralysis caused by previous surgery (arytenoid adduction thyroplasty group) were enrolled in this study. Preoperative phonation efficiency index was significantly lower (p = .008) in the fixed vocal cord group than in the mobile vocal cord group. One year after surgery, all voice parameters of the patients in the fixed vocal cord group had improved, compared with their preoperative data. The fixed vocal cord group had attained satisfactory voice qualities equivalent to those of the mobile vocal cord group in terms of various voice parameters. The present results support the idea that immediate RLN reconstruction at the time of surgery for thyroid cancers may spare the need for subsequent arytenoid adduction thyroplasty even in the patients with preoperatively fixed vocal cords. © 2016 Wiley Periodicals, Inc.

To determine if pretreatment with topical nonsteroidal anti-inflammatory drug (NSAID) prior to femtosecond laser-assisted cataract surgery (FLACS) prevents intraoperative prostaglandin level elevation as a potential risk factor of postoperative complications. Thirty-six patients with clinically significant cataract and without any concomitant general or ophthalmic disease were enrolled into the three age-matched groups of the study. The mean age of the patients was 62.3 ± 13.1 years. The first group of patients underwent traditional phacoemulsification (Control group), on the second group of patients FLACS was performed, and the third group of patients received topical 0.1% nepafenac pretreatment for 1one day prior to FLACS. Before the phacoemulsification part of the cataract surgery, approximately 110 µL of aqueous humor was collected in all groups. Total prostaglandin concentrations of the collected aqueous humor samples were evaluated by enzyme immunoassay (EIA). The mean of the total prostaglandin concentrations of the aqueous humor samples was 208.8 ± 140.5 pg/mL in patients in the control group, 1449.1 ± 1019.7 pg/mL in the FLACS group (p > 0.001), and 92.2 ± 51.7 pg/mL in the group pretreated with topical NSAID before the FLACS (p > 0.001 compared to FLACS; p > 0.01 compared to control), respectively. FLACS surgery increases intracameral prostaglandin concentration. However, using preoperative 1-day-long nonsteroid anti-inflammatory drops prior to FLACS, this intraoperative increase diminishes. Our study raises the possibility that NSAID pretreatment may be routinely administered before FLACS cataract surgeries to achieve a further decrease in the potential complications of increased total prostaglandin concentration during FLACS surgeries.

Caudal anesthesia is widely used as intraoperative and postoperative analgesia in children's subumbilical surgeries such as on the urogenital system, lower extremities and lower abdomen to reduce the stress response to surgery and to facilitate the general anesthesia. The purpose of this study was to compare the effects of caudally administered bupivacaine and levobupivacaine of equal volume and concentration on motor block and postoperative pain in children undergoing circumcision surgery. The prospective, randomized, double-blind study included 60 patients with ages ranging from 1-10 years and ASA (American Society of Anesthesiologists) physical status of I-II who underwent elective circumcision surgery. The patients were divided into two groups: group B received 0.5 ml/kg of bupivacaine 0.25% caudally and group L received 0.5 ml/kg of levobupivacaine 0.25% caudally. Postoperative pain was assessed by children's and infant's postoperative pain scale and motor block was assessed by the Bromage scale. The mean children's and infant's postoperative pain scale of group B was significantly lower than that of group L (p < 0.001). Three patients in group B and seven patients in group L needed additional analgesia after the incision. There was no significant difference between groups in terms of Bromage scores and in both groups the residual motor block was found to be zero at the 150th minutes. According to these findings, bupivacaine has an adequate quality of analgesia than levobupivacaine. We suggest that bupivacaine for caudal block at the concentration of 0.25% (0.5 ml/kg) provides an adequate level of analgesia for outpatient circumcision surgery.

Children with epilepsy have elevated rates of behavior problems. Research findings on the impact of epilepsy surgery on children's behavior have been mixed, with some studies showing improvements in behavior 3 to 18 months after surgery and other studies finding no change within this time interval. We examined behavior in a large surgical sample and in a nonsurgical comparison group. We also examined for potential effects of epilepsy-related and cognitive/linguistic variables. Behavior was assessed by parent report in 147 children who underwent epilepsy surgery and 40 children who did not, using the Child Behavior Checklist (CBCL). For the surgical group, the CBCL was completed prior to surgery (baseline) and approximately 1 year after surgery (follow-up); ratings of the nonsurgical group were also conducted twice, at comparable intervals. At baseline, the groups did not differ on age, sex, age at seizure onset, antiepileptic drugs (AEDs), or intelligence quotient (IQ). Baseline Social and Attention Problems were higher in the nonsurgical group. At follow-up, 65% of the surgical group and 20% of the nonsurgical group were seizure-free. Behavioral change was not related to surgical status or seizure outcome. Children with temporal lobe seizure focus had more Externalizing Behaviors compared to those with frontal or multilobar foci. Attention was poorer in children who underwent frontal lobe excisions relative to temporal or multilobar excisions. Baseline IQ did not predict behavioral change. Our results suggest that surgery and seizure outcome do not affect behavior in the first year following surgery; it may be the abnormal neural substrate and not seizure control that influences behavior in children with epilepsy. If changes are to occur due to seizure freedom, they may require a longer time to emerge. Some behaviors may be resistant to change in children with epilepsy or may require even longer intervals for improvement. Wiley Periodicals, Inc. © 2015 International League Against Epilepsy.

The aim of this study is to describe the different modalities of congenital obstructing vaginal malformations and the evaluation of techniques to solve the problem. A retrospective study. The University Hospital Nijmegen, the Netherlands. The medical records of 18 patients with congenital obstructive malformations of the vagina operated on by one gynecologist were retrospectively reviewed. The conditions were classified in three groups: group I with one uterus and vagina and with a transverse vaginal septum, group II with a partial vaginal agenesis and group III with a double genital system and a septum with occlusion of one vagina. Operating technique used, mold treatment after surgery, menstruation outflow, the possibility of having intercourse and the need for additional surgery. 18 patients were evaluated. Of 10 patients in group I, 8 patients were treated with the pull-through technique and 2 patients with the push-through technique. Four of the patients with a pull-through operation did not get mold treatment; of these patients, 3 needed repeat surgery because of the tendency for constriction. Of 4 patients in group II, 1 patient was treated with the pull-through technique and 3 with the push-through technique. The patient with the pull-through technique needed repeat surgery because of constriction. There was no mold treatment after the first procedure. Group III were 4 patients all treated with the pull-through technique. None of them received mold treatment, and none of these patients needed repeat surgery. The push-through method is a good surgical technique for the patients in whom problems of constriction after surgery are expected and for patients with difficulties during surgery. Mold treatment is recommended after surgery in patients with a thick transversal vaginal septum or a partial vaginal aplasia.

The purpose of this study was to determine the effect of distraction through humor on anxiety among children having outpatient surgery, and their parents. Quasi-experimental design using a nonrandomized control group. The study assessed preoperative anxiety in child-parent dyads. The control group received usual care. The intervention group received the "Wacky Wednesday" (WW) intervention in which they entered an environment where employees were dressed in "wacky" attire and children and parents were provided with gifts and costume items. Anxiety scores, heart rate, and blood pressure were collected from patients and parents in both groups on admission and just before transfer to surgery. Children who arrived for surgery on WW had significantly lower anxiety scores on admission than children in the control group. In addition, children and parents who received the WW intervention had significantly lower anxiety scores just before surgery than those in the control group. Humor and distraction are effective with children and parents in relieving preoperative anxiety. Copyright © 2014 American Society of PeriAnesthesia Nurses. Published by Elsevier Inc.

Our aim is to investigate the effect of active ankle movement to prevent deep vein thrombosis (DVT) in patients who received lower limb surgery, and to provide a theory of evidence for rehabilitation nursing of patients after orthopedic surgery. Between January 2012 and December 2013, a total of 174 patients were randomized as case group (n = 96) and control group (n = 78). Case group received routine nursing and active ankle movement (30 times/min, 1-7 days after surgery), while control group only received routine nursing. The symptoms and signs of DVT were in real-time observation during the experiment. Thigh and crus circumference, maximum venous outflow (MVO), maximum venous capacity (MVC), and MVO ratio (MVO ratio = MVO/MVC) in the two groups were measured 1-7 days after surgery. Six-month follow-up study was also conducted to observe the occurrence of DVT. Our study revealed that thigh circumference in the case group decreased compared with the control group in 5-7 days (fifth day: 39.98 ± 3.25 vs. 41.01 ± 3.38, P = 0.043; sixth day: 38.21 ± 3.81 vs. 39.49 ± 3.79, P = 0.029; seventh day: 37.13 ± 3.15 vs. 38.76 ± 3.31, P = 0.001), and crus circumference in the case group also decreased compared with the control group in 5-7 days (fifth day: 26.35 ± 2.11 vs. 27.01 ± 2.19, P = 0.045; sixth day: 25.99 ± 2.31 vs. 26.88 ± 3.12, P = 0.032; seventh day: 25.56 ± 1.99 vs. 26.38 ± 2.89, P = 0.028). MVO and MVC in the case group increased compared with the control group 7 days after surgery (MVO: 15.01 ± 2.56 vs. 14.12 ± 2.56, P = 0.024; MVC: 10.18 ± 3.15 vs. 8.91 ± 2.78, P = 0.006). Significant difference in the incidence of thrombus and DVT were found between the case group and the control group 1-7 days after surgery (thrombus: 1.0% and 7.7%, P = 0.027; DVT: 7.6% and 18.4%, P = 0.032). Our result manifested that active ankle movement can relieve the swelling of patients after lower limb surgery, and improve the MVO and MVC of patients to prevent formation of DVT after lower limb surgery.

Introduction: The aim of this study was to assess the effect of low-level laser therapy (LLLT) on pain, swelling and maximum mouth opening in patients undergoing third molar surgery. Methods: A prospective, randomized double-blind study was undertaken on 44 patients at the Dental School, Ahvaz Jundishapur University of Medical Sciences, in 2015. A low-level laser was randomly applied on one of the two sides after surgery of 15 patients. The experimental side received 18 J/cm2 of energy density, wavelength of 980 nm, and output power of 1.8 W. On the control side, a hand-piece was applied intra-orally, but laser was not activated. In addition, in order to evaluate trismus, 13 patients were treated by unilateral laser therapy and 16 patients did not receive laser therapy at all. The laser was administered intraorally on two points of vestibular and lingual sides at 1 cm from the surgery site, and extraorally at the emergence of the masseter muscle, immediately after surgery, and repeated 24 hours later. The pain, swelling and maximum mouth opening (MMO) were compared between the two groups at 24 hours and a week after surgery. Results: The mean score of pain 24 hours after surgery in the laser therapy group (2.3 ± 3.5) was significantly lower than the mean score of pain in the drug therapy (4.19 ± 3.09) (P = 0.036). Moreover, the mean score of pain at one week after surgery in the laser therapy group (0.13 ± 2.33) was significantly lower than the drug therapy group (1.43 ± 2.45) (P = 0.046). The amount of swelling according to different measurements did not significantly differ between the two groups neither at 24 hours nor at 1 week after surgery. Conclusion: Our findings showed that LLLT was useful in reducing pain and could slightly reduce swelling compared to drug therapy in impacted third molar surgery. PMID:28912943

The aim of the present study was to assess the efficacy of a thrombin-based topical haemostatic in reducing blood requirements after total knee replacement (TKR) revision surgery. This prospective, randomized, controlled study was designed to evaluate the haemostatic efficacy and safety of a thrombin-based topical haemostatic (Floseal) versus standard treatment in patients receiving total knee revision arthroplasty. The decrease in haemoglobin values postsurgery and the blood units transfused were recorded. The decision to transfuse was made by a surgeon blinded to the patient's group allocation. Forty-eight patients were enroled in the study; twenty-four patients each were randomized to the treatment and control groups, respectively. The median decrease in haemoglobin concentration on the first postoperative day was 2.2 g/dL in the treatment group and 2.7 g/dL in the control group. A significant reduction in units of blood transfused was also observed in the treatment group compared with the control group [1.1 ± 1.13 (range 0-4) vs. 1.9 ± 1.41 (range 0-5) blood units; P = 0.04]. No major treatment-related adverse events were recorded in the study. This study shows that a thrombin-based topical haemostatic reduces the need for blood transfusion in TKR revision surgery. A thrombin-based topical haemostatic agent can be an appropriate solution to enhance haemostasis and vessel sealing at the operative site in TKR revision surgery, in order to reduce the need for blood transfusion after surgery.

Retrospective study. Local infiltration analgesia is effective in many surgeries as knee arthroplasty, but the analgesic efficacy of local infiltration analgesia with ropivacaine in trauma spine surgery in T10 to L2 has not been clarified. We conducted a trial to assess the analgesic efficacy of intraoperative local infiltration analgesia (LIA) with ropivacaine. The aim of the present study was to clarify the effect of intraoperative local infiltration analgesia with ropivacaine on postoperative pain for patients undergoing thoracolumbar junction fracture surgery. In a retrospective study, in 76 patients undergoing spine surgery for thoracolumbar junction fracture, 20ml of ropivacaine 7.5% (n R group=38) was infiltrated using a systematic technique, or no infiltration was realized (n M group=38). We assessed postoperative pain with Visual Analogue Scale (VAS) and morphine consumption in the 24 first hours. VAS pain score upon awakening and at 2hours postoperatively were significantly lower in the ropivacaine group (P=0.01 and P=0.002). Rescue opioid requirement during the 24 first hours were about 50% lower in the ropivacaine group (P=0.01). No local or systemic side effects were observed. Intraoperative LIA with ropivacaine in thoracolumbar junction fracture surgery may have an analgesic effect in postoperative pain control (24hours) with a reduction of VAS and morphine consumption.

To evaluate the effects of gum chewing combined with a semi-liquid diet on patients after gynaecologic laparoscopic surgery. Previous studies suggested that chewing gum before traditional postoperative care promotes the postoperative recovery of bowel motility and function after open and laparoscopic surgery. However, gum chewing combined with a semi-liquid diet has not been reported in postoperative care of patients following gynaecologic laparoscopic surgery. A prospective randomised study. Total 234 patients were randomly assigned after elective gynaecologic laparoscopic surgery to a gum chewing and semi-liquid diet group, a semi-liquid only diet group or a liquid diet group. The gum chewing and semi-liquid diet group chewed sugar-free gum with an oral intake of a semi-liquid diet six hours postoperatively. The semi-liquid only diet and liquid diet groups received a semi-liquid diet or a liquid diet, respectively. The time to first bowel sounds, time to first regular postoperative bowel sounds, time to first passage of flatus, time to first defecation, serum gastrin and incidences of hunger, nausea, vomiting and abdominal distension were recorded. Hunger and gastrointestinal sensations were assessed using a four-point scale. Serum gastrin was assayed pre- and postoperatively using a gastrin radioimmunoassay kit. The gum chewing and semi-liquid diet group had first bowel sounds, first regular bowel sounds, first passage of flatus and first defecation earlier than the semi-liquid only and liquid groups. Increased serum gastrin was observed in the gum chewing and semi-liquid diet group. Incidences of nausea, vomiting and abdominal distention were not significantly different between these groups. Chewing gum combined with an oral intake of a semi-liquid diet is safe and accelerates the postoperative recovery of bowel function. It might be recommended as a better postoperative care regimen for patients after gynaecologic laparoscopic surgery. This study developed a new postoperative diet regimen to improve the postoperative care of patients undergoing laparoscopic gynecologic surgery. © 2016 John Wiley & Sons Ltd.

To assess the long-term effect of bariatric surgery on the incidence of gout and hyperuricaemia in participants of the Swedish Obese Subjects (SOS) study. This report includes 1982 subjects who underwent bariatric surgery and 1999 obese controls from the SOS study, a prospective intervention trial designed to assess the effect of bariatric surgery compared with conventional treatment. None of the subjects had gout at baseline. An endpoint on gout incidence was created based on information on gout diagnosis and use of gout medications through national registers and questionnaires. Median follow-up for the incidence of gout was about 19 years for both groups. Moreover, the incidence of hyperuricaemia over up to 20 years was examined in a subgroup of participants having baseline uric acid levels <6.8 mg/dL. Bariatric surgery was associated with a reduced incidence of gout compared with usual care (adjusted HR 0.60, 95% CI 0.48 to 0.75, p<0.001). The difference in absolute risk between groups was 3 percentage points at 15 years, and the number of subjects needed to be treated by bariatric surgery to prevent one incident gout event was 32 (95% CI 22 to 59). The effect of bariatric surgery on gout incidence was not influenced by baseline risk factors, including body mass index. During follow-up, the surgery group had a lower incidence of hyperuricaemia (adjusted HR 0.47, 95% CI 0.39 to 0.58, p<0.001). The difference in absolute risk between groups was 12 percentage points at 15 years, and the number of participants needed to be treated by bariatric surgery to prevent hyperuricaemia was 8 (95% CI 6 to 13). Bariatric surgery prevents gout and hyperuricaemia in obese subjects. NCT01479452; Results. Published by the BMJ Publishing Group Limited.

Preoperative exposure to clopidogrel and aspirin significantly increases postoperative bleeding in patients undergoing on-pump coronary artery bypass graft surgery. Off-pump coronary bypass grafting has been proposed as an alternative technique to attenuate postoperative bleeding associated with clopidogrel. This study aimed to determine the effects of aspirin and clopidogrel therapy on perioperative blood loss and blood transfusion requirements in off-pump coronary artery bypass grafting. One hundred six patients scheduled for off-pump coronary artery bypass grafting were divided into three groups: aspirin and clopidogrel discontinued more than 6 days before surgery (group 1, n = 35), aspirin and clopidogrel continued until 3 to 5 days before surgery (group 2, n = 51), and both medications continued within 2 days of surgery (group 3, n = 20). Thromboelastographic tracings were analyzed before induction of anesthesia. Routine coagulation profiles were measured before and after surgery. A cell salvage device was used during surgery and salvaged blood was reinfused. Chest tube drainage and blood transfusion requirement were recorded postoperatively. Patient characteristics, operative data, and thromboelastographic tracings were similar among the groups. There were significant decreases in hematocrit level and platelet count and prolongation in prothrombin time postoperatively in all groups without any intergroup differences. The amounts of perioperative blood loss and blood transfusion required were all similar among the groups. Preoperative clopidogrel and aspirin exposure even within 2 days of surgery does not increase perioperative blood loss and blood transfusion requirements in patients undergoing elective off-pump coronary artery bypass grafting.

Purpose: Esophagectomy remains the mainstay treatment for esophageal cancer, although retrospective studies have suggested that chemoradiotherapy (CRT) is as effective as surgery. To determine whether CRT can substitute for surgery as the primary treatment modality, we performed a prospective direct comparison of outcomes after treatment in patients with resectable esophageal cancer who had received CRT and those who had undergone surgery. Methods and Materials: Eligible patients had resectable T1-3N0-1M0 thoracic esophageal cancer. After the surgeon explained the treatments in detail, the patients selected either CRT (CRT group) or surgery (OP group). The CRT course consisted of two cycles of cisplatinmore » and fluorouracil with split-course concurrent radiotherapy of 60Gy in 30 fractions. Patients with progressive disease during CRT and/or with persistent or recurrent disease after CRT underwent salvage resection. Results: Of 99 eligible patients with squamous cell carcinoma registered between January 2001 and December 2005, 51 selected CRT and 48 selected surgery. Of the patients in the CRT group, 13 (25.5%) underwent esophagectomy as salvage therapy. The 3- and 5-year survival rates were 78.3% and 75.7%, respectively, in the CRT group compared with 56.9% and 50.9%, respectively, in the OP group (p = 0.0169). Patients in the OP group had significantly more metastatic recurrence than those in the CRT group. Conclusions: Treatment outcomes among patients with resectable thoracic esophageal squamous cell carcinoma were comparable or superior after CRT (with salvage therapy if needed) to outcomes after surgery alone.« less

Objective Postoperative bleeding after cardiac surgery is commonly associated with hyperfibrinolysis. This study was designed to evaluate the efficacy of topical tranexamic acid in addition to intravenous tranexamic acid in reducing bleeding in cardiac surgery cases. Methods From July 1, 2014 to September 30, 2015, 82 patients who underwent elective on-pump cardiac surgery were randomized into a tranexamic acid group and a placebo group. In the tranexamic acid group, 1 g of tranexamic acid dissolved in 100 mL of normal saline solution was poured into the pericardium during sternal closure; the placebo group had 100 mL of saline only. Two patients were excluded from the study due to obvious surgical bleeding. The primary endpoint was total blood loss 24 h after surgery. Repeated measures with mixed models was used to analyze bleeding over time. Results There was no significant difference in demographic and intraoperative data except for a significantly lower platelet count preoperatively in the tranexamic acid group ( p = 0.030). There was no significant difference in postoperative drainage volumes at 8, 16, and 24 h, postoperative bleeding over time (coefficient = 0.713, p = 0.709), or blood product transfusion between the groups. There were no serious complications. Conclusions Topical tranexamic acid is safe but it adds no additional efficacy to the intravenous application in reducing postoperative blood loss. Intravenous tranexamic acid administration alone is sufficient antifibrinolytic treatment to enhance the hemostatic effects during on-pump cardiac surgery.

The use of a patient's image in plastic surgery is common today. Thus, plastic surgeons should master the use of the image and be aware of the implications of the patients' perception of themselves. The mere-exposure effect is a psychological phenomenon in which a person tends to rate things more positively merely because (s)he is familiar with them. Faces are asymmetric, so faces in photos are different from those observed in mirrors. The main objective of this study was to assess whether patients within a plastic surgery population, particularly those undergoing facial aesthetic surgery, preferred standard photographs or mirror-reversed photographs of themselves. A prospective study was conducted in a plastic surgery department, which included women who were admitted to the hospital the day before their procedures. The patients were separated into the following two groups: Group 1 was composed of patients who were undergoing facial aesthetic surgeries, and Group 2 consisted of other patients who presented to the plastic surgery department for surgery. The patients were required to rate their appreciation of their own faces and to choose between standard and mirror-reversed photos of themselves. A total of 214 patients participated. The median age was 47.9 years (interquartile range (IQR): 36.4-60.6), and the median face appreciation was 5 (IQR: 5-7). The preference for the mirror-reversed photograph was significantly different from chance (p < 0.001, binomial (214, 156, 0.5)); 73% of the patients preferred the mirror-reversed photographs. The proportions of patients who preferred the mirror-reversed photograph differed significantly (p = 0.047) between Groups 1 (84%) and 2 (70%). Plastic surgery patients have a significant preference for mirror-reversed photographs of themselves over standard photographs. This preference is even more pronounced among patients who are undergoing facial aesthetic surgery. III. Copyright © 2015 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Induced hypotension is widely used intraoperatively to reduce blood loss and to improve the surgical field during spinal surgery. To determine the effect of milrinone on induced hypotension during spinal surgery in elderly patients. Prospective randomized clinical trial. Forty patients, 60 to 70 years old, ASA I-II, who underwent elective lumbar fusion surgery. Intraoperative hemodynamics, blood loss, hourly urine output, and grade of surgical field. All patients were randomized to group M or N. The study drug was infused after perivertebral muscle retraction until complete interbody fusion. In group M, 50 μg/kg/min of milrinone was infused over 10 minutes as a loading dose followed by 0.6 μg/kg/min of milrinone as a continuous dose. In group N, an identical volume of normal saline was infused in the same fashion. This study was not funded by commercial or other sponsorship and the authors confirm no conflicts of interest, financial or otherwise. During infusion of the study drug, the systolic and mean blood pressures were maintained within adequate limits of induced hypotension in group M. Intraoperative blood loss was 445.0±226.5 mL in group M and 765.0±339.2 mL in group N (p=.001). Hourly urine output was 1.4±0.6 mL in group M and 0.8±0.2 mL in group N (p<.001). The grade of the surgical field was better in group M than in group N (p=.004). We conclude that milrinone is useful for induced hypotension in elderly patients during spinal surgery.

AIM To evalaute the effect of fixed-combination latanoprost 0.005%/timolol maleate 0.5% and dorzolamide hydrochloride 2%/timolol maleate 0.5% on postoperative intraocular pressure after phacoemulsification cataract surgery. METHODS This study is a prospective, randomized, double-masked and placebo-controlled. The study included 90 eyes of 90 patients which were scheduled to have phacoemulsification surgery. Patients were randomly assigned preoperatively to 1 of 3 groups (30 eyes of 30 patients). Two hour before surgery, the patients received one drop latanoprost/timolol (group 1), dorzolamide/timolol (group 2) and placebo (group 3, control group). The IOPs were measured at preoperative and postoperative 4, 8, and 24 hours. RESULTS The preoperative mean intraocular pressure was not statistically significant between both drug groups and control group. In group 1 and 2, the postoperative mean IOP [group1: (14.03±3.15)mmHg and group 2: (14.16±4.43)mmHg] at 24 hours were significantly lower than the control group [(16.93±3.70)mmHg, (P<0.05)]. In addition, the postoperative mean IOP of group 1 [(14.90±3.69)mmHg] at 8 hours was significantly lower than the control group [(17.70±3.89)mmHg, (P<0.05)], but there was no significant difference between group 2 [(16.16±5.23)mmHg] and control group at 8 hours (P>0.05). CONCLUSION When compared with placebo, the use of preoperative fixed combination of latanoprost/timolol and dorzolamide/timolol is an effective method for preventing intraocular pressure elevation in 24 hours after phacoemulsification surgery, but did not completely prevent IOP spikes.

In this study, we aimed to evaluate, the efficacy of surgical methods and the factors affecting the residual stone rate by scrutinizing retrospectively the patients who had undergone renal stone surgery. Records of 109 cases of kidney stones who had been surgically treated between January 2010, and July 2013 were reviewed. Patients were divided into three groups in terms of surgical treatment; open stone surgery, percutaneous nephrolithotomy (PNL) and retrograde intrarenal surgery (RIRS). Patients' history, physical examination, biochemical and radiological images and operative and postoperative data were recorded. The patients had undergone PNL (n=74; 67.9%), RIRS (n=22;20.2%), and open renal surgery (n=13; 11.9%). The mean and median ages of the patients were 46±9, 41 (21-75) and, 42 (23-67) years, respectively. The mean stone burden was 2.6±0.7 cm(2) in the PNL, 1.4±0.1 cm(2) in the RIRS, and 3.1±0.9 cm(2) in the open surgery groups. The mean operative times were 126±24 min in the PNL group, 72±12 min in the RIRS group and 82±22 min in the open surgery group. The duration of hospitalisation was 3.1±0.2 days, 1.2±0.3 days and 3.4±1.1 days respectively. While the RIRS group did not need blood transfusion, in the PNL group blood transfusions were given in the PNL (n=18), and open surgery (n=2) groups. Residual stones were detected in the PNL (n=22), open surgery (n=2), and RIRS (n=5) groups. PNL and RIRS have been seen as safe and effective methods in our self application too. However, it should not be forgotten that as a basical method, open surgery may be needed in cases of necessity.

Background The objective of this study was to appraise the prognostic role of initial pan-endoscopic tumor length at diagnosis within or between operable esophageal squamous cell carcinoma (ESCC) undergoing upfront esophagectomy or neoadjuvant concurrent chemoradiotherapy (nCCRT) followed by esophagectomy. Methods Between Jan 2001 and Dec 2013 in Koo-Foundation Sun Yat-sen Cancer Center in Taiwan, 101 ESCC patients who underwent upfront esophagectomy (surgery group) and 128 nCCRT followed by esophagectomy (nCCRT-surgery group) were retrospectively collected. Prognostic variables, including initial pan-endoscopic tumor length at diagnosis (sub-grouped ≤3, 3–5 and >5 cm), status of circumferential resection margin (CRM), and pathological T/N/M-status and cancer stage, were appraised within or between surgery and nCCRT-surgery groups. Results Within surgery group, longer initial pan-endoscopic tumor length at diagnosis (≤3, 3–5 and >5 cm; HR =1.000, 1.688 and 4.165; P=0.007) was an independent prognostic factor that correlated with advanced T/N/M-status, late cancer stage, and CRM invasion (all’s P<0.001). Based on the initial pan-endoscopic tumor length at diagnosis ≤3, 3–5 and >5 cm, nCCRT-surgery group had a poorer (P=0.039), similar (P=0.447) and better (P<0.001) survivals than did surgery group, respectively. For those with initial pan-endoscopic tumor length at diagnosis >5 cm, nCCRT-surgery group had more percentage of T0/N0-status and stage 0 (all’s P<0.05), and fewer rate of CRM invasion (P=0.036) than did surgery group. Conclusions Initial pan-endoscopic tumor length at diagnosis could be a criterion to select proper ESCC cases for nCCRT followed by esophagectomy to improve survival and reduce CRM invasion.

The utilization of surgical simulation continues to grow in medical training. The TouchSurgery application (app) is a new interactive virtual reality smartphone- or tablet-based app that offers a step-by-step tutorial and simulation for the execution of various operations. The purpose of this study was to compare the efficacy of the app versus traditional teaching modalities utilizing the "Carpal Tunnel Surgery" module. We hypothesized that users of the app would score higher than those using the traditional education medium indicating higher understanding of the steps of surgery. A total of 100 medical students were recruited to participate. The control group (n = 50) consisted of students learning about carpal tunnel release surgery using a video lecture utilizing slides. The study group (n = 50) consisted of students learning the procedure through the app. The content covered was identical in both groups but delivered through the different mediums. Outcome measures included comparison of test scores and overall app satisfaction. Test scores in the study group (89.3%) using the app were significantly higher than those in the control group (75.6%). Students in the study group rated the overall content validity, quality of graphics, ease of use, and usefulness to surgery preparation as very high (4.8 of 5). Students utilizing the app performed better on a standardized test examining the steps of a carpal tunnel release than those using a traditional teaching modality. The study findings lend support for the use of the app for medical students to prepare for and learn the steps for various surgical procedures. This study provides useful information on surgical simulation, which can be utilized to educate trainees for new procedures. Copyright © 2017 American Society for Surgery of the Hand.

Implementation study. To describe the development and potential value of the New Zealand (NZ) upper limb surgery registry and report the demographic and spinal cord injury characteristics of individuals with tetraplegia collated to date. Multi Center-coordinated from Burwood Spinal Unit, NZ. Following discussions with eight international units, clinical information and outcomes measures were agreed upon for use in this specific population. To implement this consensus, a web-based upper limb surgery registry was developed in NZ. Inclusion criteria included referral to a hand clinic for clinical assessment for suitability for tendon transfer surgery. Clinical data were collected regardless of acceptance of surgery thereby creating a self-selected control group. Twenty-eight years of retrospective NZ data was entered into the registry, as well as 3 years of prospective data collected in NZ. From 1982 to 2013, a total of 357 persons with tetraplegia were assessed as suitable for surgery. Of those, 223 individuals underwent surgery and 134 declined the intervention(s). The prospective group currently comprises 55 assessments with 23 surgery individuals and 32 who have declined surgery to date. Clinical information is now available within a web-based registry for all individuals reviewed in hand clinics from when upper limb surgery was first introduced. A broad range of outcomes of interest can easily be reported directly from the registry. The self-selected control group will allow comparative studies to be explicitly linked to the specific interventions of interest.

The aim of this study was to compare the visual outcomes, intraocular pressure (IOP), and endothelial cell loss caused by trabeculectomy (TRAB) and Ahmed glaucoma valve (AGV) implantation in patients who had previously undergone penetrating keratoplasty (PKP). The data from all patients who underwent surgical treatment of glaucoma after PKP were reviewed at the Cornea Department of Haydarpasa Numune Education and Research Hospital. Eighteen patients who had undergone surgical treatment of glaucoma after PKP were included in this retrospective study. Time between PKP and glaucoma surgeries, visual acuity results, IOP results, endothelial cell counts (ECC) before the surgery, at 1st, 6th, and 12th month of surgery were recorded. Differences between two groups were evaluated. Mean loss of ECC was 315 cells/mm(2) in the AGV group and 197 cells/mm(2) in TRAB group at 12th month of glaucoma surgery. The difference between endothelial cell loss at 12th month of surgery was statistically significant and higher in AGV group (p < 0.001). The decrease in IOP was 64.2 % in AGV group and 46.9 % in TRAB group at 12th month of surgery. Both differences were statistically significant between 2 groups (p = 0.001, 0.001). TRAB successfully decreased both the IOP and endothelial cell loss in patients with post-PKP glaucoma. Ahmed glaucoma valve had a significantly better IOP lowering but higher endothelial cell loss effect.

To investigate the aorta movement following correction surgery for patients with thoracolumbar/lumbar scoliosis and to determine the subsequent risk of the aorta impingement for pedicle screw (PS) misplacement. Thirty-six AIS patients with a main thoracolumbar or lumbar curve were included in this study. According to the direction of the main curve, the patients were divided into Group R and Group L, with Group R comprising 16 patients with a right-sided curve and Group L comprising 20 patients with a left-sided curve. All patients underwent CT scans of the lower thoracic and lumbar spine before and after surgery. To identify the relative positions of the aorta to vertebral body, several parameters were measured from the CT images of the middle transverse planes of vertebrae from T11 to L4, including aorta-vertebra angle (α), vertebral rotation angle (β), left safety distance (LSD) and right safety distance (RSD). The risk of the aorta impingement from T11 to L4 was calculated. An intragroup comparison regarding the position of the aorta relative to the vertebral body before and after correction surgery was performed accordingly. After surgery, the aorta moved toward the vertebral body among all levels in both groups. Compared with that in Group L, the aorta in Group R was significantly closer to the entry point at all levels, especially at T11. Before surgery, the aorta in Group R was at a high risk of impingement from left PS placement regardless of the diameters of the simulated screws. While in Group L, the risk of aorta impingement was mainly caused by the right placement of 45 mm PS. After surgery, both groups had an increased risk of aorta impingement from PS insertion, especially at T11. The risk of aorta impingement from PS placement was significantly higher in Group R than in Group L. The risk of aorta impingement increased as the aorta shifted leftward after correction surgery, especially in right-sided Lenke 5C curve. Thus, preoperative risk evaluation could be insufficient for clinical practice due to aorta movement following correction surgery. Surgeons should be aware of the potential risk of aorta impingement, especially when placing PS in patients with right-sided curves.

Background Ketamine, an N-methyl-D-aspartate receptor antagonist, can suppress hyperalgesia and allodynia. The purpose of the present study was to evaluate the clinical efficacy of preincisional intravenous or subcutaneous infiltration of ketamine for postoperative pain relief after appendectomy. Methods Ninety patients, aged 18–60 years, scheduled for appendectomy was enrolled in this study. Patients were divided into three groups of 30 each and received subcutaneous infiltration of ketamine 0.5 mg/kg (KS), intravenous ketamine 0.5 mg/kg (KI), or subcutaneous infiltration of normal saline 3 mL (C) before surgery. Visual analog scale (VAS) values and analgesic consumption were evaluated for 24 hours after surgery. Results VAS scores were significantly lower at the time of arrival in the recovery room, and at 10, 20, and 30 minutes thereafter in group KI and group KS compared with group C (P < 0.05). VAS scores were not significantly different between group KI and group KS at these intervals. Postoperative VAS scores were significantly lower at 6, 12, 18, and 24 hours in group KI compared with group C (P < 0.05). In group KS, the postoperative VAS score was significantly lower at 6 hours (P < 0.05). VAS scores were significantly lower at 12, 18, and 24 hours after surgery in group KI compared with group KS (P < 0.05). Conclusion A 0.5 mg/kg dose of ketamine given at approximately 15 minutes before surgery by the intravenous route provided analgesia for 24 hours after surgery in patients undergoing appendectomy.

Surgery because of disc herniation or spinal stenosis results mostly in large improvement in the short-term, but mild to moderate improvements for pain and disability at long-term follow-up. Prehabilitation has been defined as augmenting functional capacity before surgery, which may have beneficial effect on outcome after surgery. The aim was to study if presurgery physiotherapy improves function, pain, and health in patients with degenerative lumbar spine disorder scheduled for surgery. A single-blinded, two-arm, randomized controlled trial (RCT). A total of 197 patients were consecutively included at a spine clinic. The inclusion criteria were patients scheduled for surgery because of disc herniation, spinal stenosis, spondylolisthesis, or degenerative disc disease (DDD), 25-80 years of age. Primary outcome was Oswestry Disability Index (ODI). Secondary outcomes were pain intensity, anxiety, depression, self-efficacy, fear avoidance, physical activity, and treatment effect. Patients were randomized to either presurgery physiotherapy or standardized information, with follow-up after the presurgery intervention as well as 3 and 12 months post surgery. The study was funded by regional research funds for US$77,342. No conflict of interest is declared. The presurgery physiotherapy group had better ODI, visual analog scale (VAS) back pain, EuroQol-5D (EQ-5D), EQ-VAS, Fear Avoidance Belief Questionnaire-Physical Activity (FABQ-PA), Self-Efficacy Scale (SES), and Hospital Anxiety and Depression Scale (HADS) depression scores and activity level compared with the waiting-list group after the presurgery intervention. The improvements were small, but larger than the study-specific minimal clinical important change (MCIC) in VAS back and leg pain, EQ-5D, and FABQ-PA, and almost in line with MCIC in ODI and Physical Component Summary (PCS) in the physiotherapy group. Post surgery, the only difference between the groups was higher activity level in the physiotherapy group compared with the waiting-list group. Presurgery physiotherapy decreases pain, risk of avoidance behavior, and worsening of psychological well-being, and improves quality of life and physical activity levels before surgery compared with waiting-list controls. These results were maintained only for activity levelspost surgery. Still, presurgery selection, content, dosage of exercises, and importance of being active in a presurgery physiotherapy intervention is of interest to study further to improve long-term outcome.

2013-04-01

Postoperative neurological deficits are one of the risks associated with cardio vascular surgery, necessitating development of new techniques for cerebral monitoring. In this study an experimental observation regarding the dynamics of transcephalic Electrical Bioimpedance (EBI) in patients undergoing cardiac surgery with and without extracorporeal circulation (ECC) was conducted to investigate the potential use of electrical Bioimpedance for cerebral monitoring in cardio vascular surgery. Tetrapolar transcephalic EBI measurements at single frequency of 50 kHz were recorded prior to and during cardio vascular surgery. The obtained results show that the transcephalic impedance decreases in both groups of patients as operation starts, however slight differences in these two groups were also observed with the cerebral impedance reduction in patients having no ECC being less common and not as pronounced as in the ECC group. Changes in the cerebral impedance were in agreement with changes of haematocrit and temperature. The origin of EBI changes is still unexplained however these results encourage us to continue investigating the application of electrical bioimpedance cerebral monitoring clinically.

Light information is the most important cue of circadian rhythm which synchronizes biological rhythm with external environment. Circadian misalignment of biological rhythm and external environment is associated with increased risk of depression, insomnia, obesity, diabetes, cardiovascular disease, and cancer. Increased light transmission by cataract surgery may improve circadian misalignment and related health outcomes. Although some observational studies have shown improvement of depression and insomnia after cataract surgery, randomized controlled trials are lacking. We will conduct a parallel-group, assessor-blinded, simple randomized controlled study comparing a cataract surgery group at three months after surgery with a control group to determine whether cataract surgery improves depressive symptoms, sleep quality, body mass regulation, and glucose and lipid metabolism. We will recruit patients who are aged 60 years and over, scheduled to receive their first cataract surgery, and have grade 2 or higher nuclear opacification as defined by the lens opacities classification system III. Exclusion criteria will be patients with major depression, severe corneal opacity, severe glaucoma, vitreous haemorrhage, proliferative diabetic retinopathy, macular oedema, age-related macular degeneration, and patients needing immediate or combined cataract surgery. After baseline participants will be randomized to two groups. Outcomes will be measured at three months after surgery among the intervention group, and three months after baseline among the control group. We will assess depressive symptoms as a primary outcome, using the short version geriatric depression scale (GDS-15). Secondary outcomes will be subjective and actigraph-measured sleep quality, sleepiness, glycated haemoglobin, fasting plasma glucose and triglyceride, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, body mass index, abdominal circumference, circadian rhythms of physical activity and wrist skin temperature, and urinary melatonin metabolite. Chronotype and visual function will be assessed using the 'morningness-eveningness' questionnaire, the Munich chronotype questionnaire, and the National Eye Institute Visual Function Questionnaire. Although there are potential limitations due to the difference in duration from baseline survey to outcome measurements between two groups, any seasonal effect on the outcome measurement will be balanced as a result of continuous inclusion of participants through the year, and outcomes will be adjusted for day length at outcome measurements at analysis.

Patients undergoing general anesthesia for laparoscopic cholecystectomy are at high risk for postoperative nausea and vomiting (PONV). This study compared ramosetron and ondansetron in terms of efficacy for PONV prevention after laparoscopic cholecystectomy. For this study, 120 patients scheduled to undergo laparoscopic cholecystectomy were randomized (in double-blind fashion) to receive 4 mg of ondansetron (group O4, n = 40), 8 mg of ondansetron (group O8, n = 40), or 0.3 mg of ramosetron (group R, n = 40) intravenously after surgery. Postoperative nausea, retching, vomiting, pain, and side effects were assessed at 2 h, 24 h, and 48 h after surgery. No statistical differences were observed among the three groups with regard to patient characteristics and information on surgery and anesthesia. The ratio of complete response (no PONV for 2 h) was higher for groups O8 and R than for group O4 as follows: 80% (n = 32) for groups O8 and R versus 58% (n = 23) for group O4 during the first postoperative 2 h (p = 0.04), 90% (n = 36) for groups O8 and R versus 76% (n = 30) for group O4 over 24 h (2-24 h) (p = 0.09), and 98% (n = 38) for groups O4 and O8 versus 100% (n = 40) for group R over the next 24 h (24-48 h) after surgery (p = 0.36). During the first 2 h after surgery, rescue antiemetics were used for significantly fewer patients in groups O8 and R (20%) than in group O4 (42.5%) (p = 0.04). Postoperative pain and the use of rescue analgesics were comparable among the groups. There was no clinically serious adverse event due to the study drugs. Ramosetron 0.3 mg and ondansetron 8 mg are more effective than ondansetron 4 mg for the prevention of PONV (2 h). Ramosetron 0.3 mg is as effective as ondansetron 8 mg for the prophylaxis of PONV after laparoscopic cholecystectomy.

Intra-operative incidental contamination of surgical wounds is not rare. Povidone-iodine solution can be used to disinfect surgical wounds. Although povidone-iodine is a good broad-spectrum disinfecting agent, it has occasionally been reported to have a negative effect on wound healing and bone union. Therefore, its safety in a spinal surgery is unclear. A prospective, single-blinded, randomized study was accordingly conducted to evaluate the safety of povidone-iodine solution in spinal surgeries. Ascertained herein was the effect of wound irrigation with diluted povidone-iodine solution on wound healing, infection rate, fusion status and clinical outcome of spinal surgeries. From January 2002 to August 2003, 244 consecutive cases undergoing primary instrumented lumbosacral posterolateral fusion due to degenerative spinal disorder with segmental instability had been collected and randomly divided into two groups: the study group (120 cases, 212 fusion levels) and the control group (124 cases, 223 fusion levels). Excluded were those patients with a prior spinal surgery, spinal trauma, malignant tumor, infectious spondylitis, rheumatoid arthritis, ankylosing spondylitis, metabolic bone disease, skeletal immaturity or with an immunosuppressive treatment. In the former group, wounds were irrigated with 0.35% povidone-iodine solution followed by normal saline solution just before the bone-grafting and instrumentation procedure. However, only with normal saline solution in the latter. All the operations were done by the same surgeon with a standard technique. All the patients were treated in the same postoperative fashion as well. Later on, wound healing, infection rate, spinal bone fusion and clinical outcome were evaluated in both groups. A significant improvement of back and leg pain scores, modified Japanese Orthopedic Association function scores (JOA) and ambulatory capacity have been observed in both groups. One hundred and seven patients in the study group and one hundred and nine in the control group achieved solid union. There was no infection in the study group but six deep infections in the control group. Wound dehiscence was noted in one group 1 and two group 2 patients. A subsequent statistical analysis revealed higher infection rate in the control group (P<0.05), but no significant difference in fusion rate, wound healing, improvement of pain score, function score and ambulatory capacity between the two groups. Diluted povidone-iodine solution can be used safely in spinal surgeries, and it will not influence wound healing, bone union and clinical outcome.

To compare the efficacy of a transdermal buprenorphine patch (5, 10, 15, and 20 μg/h) with that of oral tramadol (150, 200, 250, and 300 mg) for postoperative pain control after single level spinal fusion surgery. The present study (ClinicalTrials.gov, number NCT02416804) was a prospective, randomized controlled non-inferiority trial designed to determine the efficacy of buprenorphine TDS for alleviating postoperative pain following patient controlled analgesia (PCA) in persons underwent a single level posterior lumbar interbody fusion surgery through 1:1 allocation. The primary outcome was the Visual Analog Pain Scale (VAS) score for postoperative back pain at 7 days after surgery. The non-inferior margin of the VAS was set at δ = 1.5 points. The VAS score (primary outcome) for postoperative back pain at 7 days after surgery in the Buprenorphine group was not inferior compared to the Tramadol group. The overall changes in VAS scores for postoperative pain during follow-up assessments over a 2-week period did not differ between both groups. However, the VAS scores for postoperative pain significantly improved with time after surgery in both groups. The patterns of changes in the VAS scores for postoperative pain during the follow-up period were not significantly different between the both groups. The efficacy of buprenorphine TDS was not inferior to that of oral tramadol medication for alleviating postoperative pain in the subacute period from 72 h after surgery, following PCA administration. In addition, adverse events were similar between both groups.

An increasing number of patients presenting for urgent coronary surgery have been exposed to clopidogrel, which constitutes a risk of bleeding and related events. Based on the wide variability in clopidogrel response and platelet function recovery after cessation, we evaluated the role of point-of-care platelet function testing to define the optimal time for off-pump coronary artery bypass graft (CABG) surgery in a case-control study. Three equally matched groups (300 patients in total) undergoing isolated off-pump CABG for acute coronary syndrome were compared. Group A were treated with clopidogrel and prospectively underwent a strategy guided by platelet function testing. Outcomes were compared with 2 propensity score matched groups: group B underwent CABG after the currently recommended 5 days without clopidogrel; group C were never exposed to clopidogrel. Patients in group A had reduced postoperative bleeding compared with those in group B (523±202 mL vs 851±605 mL; P<.001) and a lower number of units packed red blood cells (PRBCs) transfused during the postoperative hospital stay (1.2±1.6 units vs 1.9±1.8 units; P=.004). Postoperative bleeding and the number of units of PRBCs transfused were similar in group A and group C. There was no difference in blood-derived products and platelet consumption, mortality, or the need for reoperation among the groups. Patients in group A waited 3.6±1.7 days for surgery. The strategy used for group A saved 280 days of hospital stay in total. The strategy guided by platelet function testing for off-pump CABG offers improved guidance for optimal timing of CABG in patients treated with clopidogrel. This strategy significantly reduces postoperative bleeding and blood consumption, and has a shorter waiting time for surgery than current clinical practice.

To determine the level of depression in women during the early post-operative period. 220 women treated surgically for various gynecologic conditions were enrolled. The study was done between day 4-6 after surgery using Beck's Depression Inventory (BDI). The results were analyzed statistically. It was found that the mean level of depression on the BDI scale in the study group of women was 12.24 +/- 8.73. The mean level of depression in patients who underwent surgery using the vaginal route was significantly greater (p = 0.003) than in patients after laparoscopy and patients after laparotomy. The mean level of depression in the study group approached values found in depression. Patients after surgery using the vaginal route demonstrated higher levels of depression than patients after laparoscopy. Age, education, source of subsistence, and number of children had an impact on the level of depression in the study group. Marital status and place of residence were without effect on the level of depression in the patients.

To present an economic-analysis comparison of simultaneous and sequential bilateral cataract surgery. Helsinki University Eye Hospital, Helsinki, Finland. Economic analysis. Effects were estimated from data in a study in which patients were randomized to have bilateral cataract surgery on the same day (study group) or sequentially (control group). The main clinical outcomes were corrected distance visual acuity, refraction, complications, Visual Function Index-7 (VF-7) scores, and patient-rated satisfaction with vision. Health-care costs of surgeries and preoperative and postoperative visits were estimated, including the cost of staff, equipment, material, floor space, overhead, and complications. The data were obtained from staff measurements, questionnaires, internal hospital records, and accountancy. Non-health-care costs of travel, home care, and time were estimated based on questionnaires from a random subset of patients. The main economic outcome measures were cost per VF-7 score unit change and cost per patient in simultaneous versus sequential surgery. The study comprised 520 patients (241 patients included non-health-care and time cost analyses). Surgical outcomes and patient satisfaction were similar in both groups. Simultaneous cataract surgery saved 449 Euros (€) per patient in health-care costs and €739 when travel and paid home-care costs were included. The savings added up to €849 per patient when the cost of lost working time was included. Compared with sequential bilateral cataract surgery, simultaneous bilateral cataract surgery provided comparable clinical outcomes with substantial savings in health-care and non-health-care-related costs.

Intraoperative computed tomography (iCT) is a reliable method for the detection of residual tumour, but previous single-slice low-resolution computed tomography (CT) without coronal or sagittal reconstructions was not of adequate quality for clinical use. The present study evaluated the results of multi-slice iCT-assisted endoscopic transsphenoidal surgery for pituitary macroadenoma. This retrospective study included 30 consecutive patients with newly diagnosed or recurrent pituitary macroadenoma with supradiaphragmatic extension who underwent endoscopic transsphenoidal surgery using iCT (eTSS+iCT group), and control 30 consecutive patients who underwent conventional endoscope-assisted transsphenoidal surgery (cTSS group). The tumour volume was calculated by multiplying the tumour area by the slice thickness. Visual acuity and visual field were estimated by the visual impairment score (VIS). The resection extent, (preoperative tumour volume - postoperative residual tumour volume)/preoperative tumour volume, was 98.9% (median) in the eTSS+iCT group and 91.7% in the cTSS group, and had significant difference between the groups (P = 0.04). Greater than 95 and >90% removal rates were significantly higher in the eTSS+iCT group than in the cTSS group (P = 0.02 and P = 0.001, respectively). However, improvement in VIS showed no significant difference between the groups. The rate of complications also showed no significant difference. Multi-slice iCT-assisted endoscopic transsphenoidal surgery may improve the resection extent of pituitary macroadenoma. Multi-slice iCT may have advantages over intraoperative magnetic resonance imaging in less expensive, short acquisition time, and that special protection against magnetic fields is not needed.

This study evaluates endoscopic and quality of life (QoL) outcomes in two groups, composed by both allergic (A) and non-allergic (N-A) adolescents undergoing septoplasty with concurrent turbinate surgery by radiofrequency treated after surgery with nasal spray containing liposomes and vitamins A and E. This double-blind randomized study was carried out on 40 patients (22 males, 18 females, mean age 15.5±1.0 years) undergoing septoplasty and volumetric tissue reduction of inferior turbinates by radiofrequency for post-traumatic deformities and severe nasal obstruction. We enrolled 20 subjects with positive skin prick tests and 20 with negative skin prick tests (SPT) to aeroallergens. All subjects underwent the Visual Analogue Scale (VAS) questionnaire and the nasal endoscopy score by Lund and Kennedy (LK) at baseline before surgery (T0) and 15 days (T15) and 21 days (T21) after treatment. After surgery, the nose was not packed and the day after surgery all subjects were randomized into two groups, experimental arm group I (GI) and control arm group II (GII) and given the treatment, nasal spray containing liposomes composed of phospholipids, fatty acids, and vitamin A and E for group I and saline solution (sodium chloride 0.9%) for group II. After therapy, the VAS and LK scores were better (P<0.05) in the investigational than in the control arm in both sub-groups (A and N-A). Our findings suggested that liposomal, vitamins A and E nasal spray improves the QoL in the early postoperative period, both in A and N-A sub-groups.

Adequate bleeding control is essential for the success of periapical surgery. The aim of this study was to evaluate the effects of 2 hemostatic agents on the outcome of periapical surgery and their relationship with patient and teeth parameters. A prospective study was designed with 2 randomized parallel groups, depending on the hemostatic agent used: gauze impregnated in epinephrine (epinephrine group) and aluminum chloride (aluminum chloride group). The analysis of the hemorrhage control was judged before and after the application of the hemostatic agents by the surgeon, and 2 examiners independently recorded it as adequate (complete hemorrhage control) or inadequate (incomplete hemorrhage control). Ninety-nine patients with a periradicular lesion were enrolled in this study and divided into 2 groups: gauze impregnated in epinephrine in 48 patients (epinephrine group) or aluminum chloride in 51 (aluminum chloride group). In epinephrine group adequate hemostasis was achieved in 25 cases, and in aluminum chloride group it was achieved in 37 cases (P < .05). The outcome was better in the aluminum chloride group than in the gauze impregnated in epinephrine group. Copyright © 2016 American Association of Endodontists. Published by Elsevier Inc.

A good patient-surgeon relationship relies on adequate preoperative education and counseling. Several multimedia resources, such as web-based education tools, have become available to enhance aspects of perioperative care. The purpose of this study was to evaluate the effect of an interactive web-based education tool on perioperative patient satisfaction scores after outpatient orthopaedic surgery. It was hypothesized that web-based education prior to outpatient orthopaedic surgery enhances patient satisfaction scores. Randomized controlled trial; Level of evidence, 1. All patients undergoing knee arthroscopy with meniscectomy, chondroplasty, or anterior cruciate ligament reconstruction or shoulder arthroscopy with rotator cuff repair were eligible for inclusion and were randomized to the study or control group. The control group received routine education by the surgeon, whereas the study group received additional web-based education. At the first postoperative visit, all patients completed the OAS CAHPS (Outpatient and Ambulatory Surgery Consumer Assessment of Healthcare Providers and Systems) survey. Differences in patient satisfaction scores between the study and control groups were determined with an independent t test. A total of 177 patients were included (104 [59%] males; mean age, 42 ± 14 years); 87 (49%) patients were randomized to receive additional web-based education. Total patient satisfaction score was significantly higher in the study group (97 ± 5) as compared with the control group (94 ± 8; P = .019), specifically for the OAS CAHPS core measure "recovery" (92 ± 13 vs 82 ± 23; P = .001). Age, sex, race, workers' compensation status, education level, overall health, emotional health, procedure type and complexity, and addition of a video did not influence patient satisfaction scores. Supplemental web-based patient education prior to outpatient orthopaedic surgery enhances patient satisfaction scores.

The purpose of this study was to compare quality of life (QoL) and the survival rate after surgery with and without radiotherapy versus superselective intra-arterial chemoradiotherapy (SSIACRT) for advanced cancer of the tongue and floor of the mouth. Patients with stage III and IV squamous cell carcinoma of the tongue and floor of the mouth treated between 2000 and 2013 were included in this study. The predictor variables were surgery without radiotherapy, surgery followed by radiotherapy, and SSIACRT. The outcome variables were QoL and the survival rate. The University of Washington QoL questionnaire (UW-QOL) was used for evaluation of QoL. The Kaplan-Meier method was used to estimate the overall survival rate. The UW-QOL was analyzed by analysis of covariance, and the survival rate was analyzed statistically by the log-rank test. Sixty-two patients were eligible for this study. Of these, 13 were treated by surgery without radiotherapy, 29 were treated by surgery plus radiotherapy, and 20 were treated by SSIACRT. The SSIACRT group had the best UW-QOL scores among the 3 groups. The 5-year Kaplan-Meier disease-specific survival rates for these groups were 92.9%, 62.9%, and 83.2%, respectively, with no significant difference (P = .20) shown. The QoL scores of the SSIACRT group were the best among the 3 groups in most domains. The superiority of QoL and the survival rate in the SSIACRT group showed that SSIACRT should be preferred in managing advanced cancer of the tongue and floor of the mouth.

To assess the efficacy of labetalol versus nitroglycerin for induction of controlled hypotension during sinus endoscopic surgery. A prospective, double-blind and randomized study. Carried out in operating room in university hospital. 60 patients of both sexes, American Society of Anesthesiologists (ASA) physical status I and II, age range from 20 to 60years; scheduled for elective sinus endoscopic surgery under general anesthesia (GA). Patients were divided into two groups (30 each). NTG group received nitroglycerin infusion at a dose of 2-5μg/kg/min, LAB group received labetalol infusion at a dose of 0.5-2mg/min. Surgical condition was assessed by surgeon using average category scale (ACS) of 0-5, a value of 2-3 being ideal. In both groups mean arterial blood pressure (MAP) was gradually reduced till the ideal ACS for assessment of surgical condition, the target of ACS was 2-3 or lower. Both studied drugs achieved desired hypotension and improved visualization of surgical field by decreasing bleeding in the surgical site, but ideal surgical conditions were created at mild hypotension (MAP 70-75) in LAB group while same conditions were created at MAP of 65-69mmHg in NTG group. Mean heart rate (HR) was significantly higher in NTG group as compared to LAB group. Blood loss decreased significantly in LAB group. Both labetalol and NTG are effective and safe drugs for induction of controlled hypotension during sinus endoscopic surgery. While, labetalol was better as it offered optimum operative condition with mild decrease in blood pressure, decreased surgical bleeding and less tachycardia during the surgery.

To investigate the impact of preoperative oral liquid carbohydrate on postoperative insulin resistance (IR) in gastric cancer patients undergoing elective resection, and to examine the association of IR index (homeostasis model assessment, HOMA-IR) with tumor necrosis factor-α (TNF-α). Between January 2013 and September 2013, 35 patients undergoing elective resection for gastric cancer were prospectively enrolled and randomized into two groups. Patients in trial group (n=18) received oral 500 ml of 10% glucose solution two hours before surgery. Patients in control group (n=17) were asked to fast for 8-12 hours before operation. About 300 mg of rectus abdominis and subcutaneous fatty tissues was removed before the closure of abdominal wall. Blood samples were collected to measure the serum concentration of TNF-α with double antibody sandwich ELISA in perioperative period (3-hour before operation, end of operation, 1-day and 3-day after operation). HOMA-IR was calculated on preoperative 3-hour and postoperative 1-day. Western blotting was used to detect protein expression of TNF-α. Correlation of HOMA-IR with TNF-α was examined. HOMA-IR on the first day after surgery was not different from that at 3-hour before surgery in trial group (P=0.090), which was significantly lower than that in control group (P=0.000). In trial group, serum TNF-α at the end of operation was higher than that at 3-hour before surgery, which declined rapidly on the first day after surgery and had no significant difference compared with that on the third day after surgery. In control group, serum TNF-α at the end of operation was also higher than that before surgery, which rose to the peak on the first day after surgery and was still higher than that at 3-hour before surgery. The TNF-α protein expression in muscle tissues of trial group was higher than that of control group (P=0.001), while no significant difference was observed between two groups in adipose tissues (P=0.987). Correlation analysis showed that HOMA-IR was positively correlated with TNF-α on the first day after surgery (r=0.832, P=0.000). Oral intake of liquid carbohydrate 2 hours before surgery can reduce the level of TNF-α, which is likely to improve the postoperative insulin resistance.

To analyze the correlation between the K-line-based classification of patients with ossification of the posterior longitudinal ligament (OPLL) and their outcome after anterior controllable antedisplacement and fusion (ACAF) surgery. A series of 24 patients with multisegmental OPLL were enrolled. All patients underwent ACAF surgery. First, the patients were classified into 2 groups according to their K-line classification. Then, we separated the patients into subgroups according to their OPLL thickness. The Japanese Orthopaedic Association scores before and 6 months after surgery were studied, and the recovery rate (RR) was calculated. The preoperative and postoperative radiologic parameters were also investigated. Clinical and radiographic assessments showed no significant correlation between the K-line-based classification of patients with OPLL and their outcome of ACAF surgery (P > 0.05). When the OPLL was ≤6 mm thick, K-line-based classification groups had a similar change of occupation ratio and RR (P > 0.05). However, when the OPLL was >6 mm thick, the mean RR was 61.8% ± 14.0% in the K-line (+) group and 78.3% ± 9.7% in the K-line (-) group (P < 0.05), and the mean was 16.0% ± 4.2% in the K-line (+) group and 28.0% ± 7.1% in the K-line (-) group (P < 0.05). This study shows that K-line can predict the clinical outcome of ACAF surgery for multisegmental OPLL in a different way from posterior decompression surgery. When the OPLL was thin, the outcome was satisfactory and there was no correlation with K-line-based classification of patients with OPLL. When the OPLL was >6 mm thick, the K-line (-) group patients had a better outcome than did K-line (+) group patients. Copyright © 2018 Elsevier Inc. All rights reserved.

To investigate the effects of oral intake of glucose solution before surgery on the pH at the lower esophagus, perioperative blood glucose level, and plasmic protein in patients undergoing radical resection for colorectal cancer. Between January 2008 and December 2008, 60 patients undergoing radical surgery for colorectal cancer were enrolled and randomized into three groups using the table of random digits. Four patients were withdrawn from the study. Patients in group A (n=19) were given 800 ml of 12.5% glucose solution for oral intake the night before surgery, and 200 ml two hours before surgery. Patients in group B (n=19) were given distilled water instead of glucose. Patients in group C (n=18) were asked to fast for 8-12 hours before operation. Combined general and epidural anesthesia was used. pH at the lower esophagus was monitored during intubation and extubation. Albumin, transferrin, prealbumin, insulin, and fasting blood glucose were measured before surgery and at postoperative day 1, 3, and 7. pH at the lower esophagus was 8.05±0.43 in group A, 7.98±0.41 in group B, and 7.94±0.41 in group C. There were no perioperative acid regurgitations (P>0.05). Serum insulin in group A at postoperative day 1 was (16.32±16.11) μU/L, which was significantly lower than that in group B (30.65±41.74) μU/L and group C (34.01±52.91) μU/L. Log HOMA-IR in group A at postoperative day 1 was significantly lower than that in group B and group C (0.49±0.35 vs. 0.59±0.56 and 0.60±0.63, P<0.05). Transferrin in group C at postoperative day 3 and 7 was significantly lower than that in the other two groups, as was albumin at postoperative day 3 (P<0.05). Oral liquid intake 2 hours before surgery is not associated with increased risk of regurgitation or aspiration during intubation and extubation, and may glucose solution intake reduce insulin resistance and protein degradation after colorectal surgery.

OBJECTIVE: The most frequent and critical complications of thyroid surgery are recurrent laryngeal nerve palsy and hypocalcemia. In first years of the 21st century, intraoperative neuromonitoring (IONM) was introduced as a new technique to avoid the recurrent laryngeal nerve (RLN) injury. However, the role and the benefits of IONM are still controversial. In this study, we aimed to compare the postoperative complication rates during thyroid surgery with IONM usage (Group 1) and conventional direct visual technique without IONM usage (Group 2). METHODS: We conducted retrospective review of all patients undergoing thyroid surgery in Lütfiye Nuri Burat State Hospital General Surgery Department between 2014 and 2016 years. Patients have been classified in to two groups: Group 1 and 2. RESULTS: Overall, 191 patients were included in the study; Group 1 comprised 79 patients and Group 2 comprised 112 patients. Unilateral RLN paralysis was observed in 7 patients in Group 1 (8.9%) and 15 patients in Group 2 (13.4%) without any significant difference between the groups (p=0.368). Hypocalcemia was encountered in 5 patients (6.3%) in Group 1 and 18 patients (16.1%) in Group 2; this difference was statistically significant (p=0.045). Other complications (such as hematoma and suture reaction) were not significantly different. Operation time was found to be significantly shorter in Group 1 (Mean time, 93.08 min) than in Group 2 (116.54 min) (p=0.03). CONCLUSION: Proven effect of IONM on RLN paralysis is still controversial. However, easy identification of RLN, which gives more confidence to surgeon, and shorter operation time may be factors to lower hypocalcemia rates. PMID:29607426

Background Alpha-2 adrenergic agonists produce safe and effective analgesia, but most investigations studying the analgesic effect of alpha-2 adrenoceptor agonists postoperatively included previous or concomitant administration of other analgesics. Because clonidine potentiates the effect of these drugs, its own intrinsic analgesic effect has been difficult to establish. This study was designed to compare the intraoperative and postoperative effects of epidural clonidine vs bupivacaine for patients undergoing lower abdominal surgery. Methods This randomized controlled trial included 40 patients aged 18-50 who were scheduled for elective lower abdominal surgery. Patients were randomly divided into 2 groups. Group I (n=20) received epidural clonidine; Group II (n=20) received epidural bupivacaine. Intraoperative and postoperative hemodynamics, pain scores, and complications were monitored. Results Mean pain scores were significantly lower in Group I compared to Group II (1.5 ± 0.5 compared to 3.4 ± 1.0, respectively) in the first 12 hours after surgery. Sedation was more prominent in Group I until 9 hours after surgery. Opioid requirements were significantly lower in Group I. Respiratory rate was similar in the 2 groups. Group I had larger decreases from baseline in systolic blood pressure and diastolic blood pressure than Group II. Heart rate in Group I was reduced from baseline, while it was increased in Group II. Less postoperative nausea and vomiting, urinary retention, pruritus, and shivering were observed in Group I. Conclusion Compared to bupivacaine, epidural clonidine provided effective intraoperative and postoperative analgesia in selected patients, resulting in a decreased intravenous pain medication requirement and prolonged duration of analgesia after epidural infusion was discontinued.

Weight loss can be influenced by genetic factors and epigenetic mechanisms that participate in the regulation of body weight. This study aimed to investigate whether the weight loss induced by two different obesity treatments (energy restriction or bariatric surgery) may affect global DNA methylation (LINE-1) and hydroxymethylation profile, as well as the methylation patterns in inflammatory genes. This study encompassed women from three differents groups: 1. control group (n = 9), normal weight individuals; 2. energy restriction group (n = 22), obese patients following an energy-restricted Mediterranean-based dietary treatment (RESMENA); and 3. bariatric surgery group (n = 14), obese patients underwent a hypocaloric diet followed by bariatric surgery. Anthropometric measurements and 12-h fasting blood samples were collected before the interventions and after 6 months. Lipid and glucose biomarkers, global hydroxymethylation (by ELISA), LINE-1, SERPINE-1, and IL-6 (by MS-HRM) methylation levels were assessed in all participants. Baseline LINE-1 methylation was associated with serum glucose levels whereas baseline hydroxymethylation was associated with BMI, waist circumference, total cholesterol, and triglycerides. LINE-1 and SERPINE-1 methylation levels did not change after weight loss, whereas IL-6 methylation increased after energy restriction and decreased in the bariatric surgery group. An association between SERPINE-1 methylation and weight loss responses was found. Global DNA methylation and hydroxymethylation might be biomarkers for obesity and associated comorbidities. Depending on the obesity treatment (diet or surgery), the DNA methylation patterns behave differently. Baseline SERPINE-1 methylation may be a predictor of weight loss values after bariatric surgery.

The aim of the study was to determine the influence of the dissection of the palate during primary surgery and the type of orthognathic surgery needed in cases of unilateral total cleft. The review concerns 58 children born with a complete unilateral cleft lip and palate and treated between 1994 and 2008 at the appropriate age for orthognathic surgery. This is a retrospective mixed-longitudinal study. Patients with syndromes or associated anomalies were excluded. All children were treated by the same orthodontist and by the same surgical team. Children are divided into 2 groups: the first group includes children who had conventional primary cleft palate repair during their first year of life, with extensive mucoperiosteal undermining. The second group includes children operated on according to the Malek surgical protocol. The soft palate is closed at the age of 3 months, and the hard palate at 6 months with minimal mucoperiosteal undermining. Lateral cephalograms at ages 9 and 16 years and surgical records were compared. The need for orthognathic surgery was more frequent in the first than in the second group (60% vs 47.8%). Concerning the type of orthognathic surgery performed, 2- or 3-piece Le Fort I or bimaxillary osteotomies were also less required in the first group. Palate surgery following the Malek procedure results in an improved and simplified craniofacial outcome. With a minimal undermining of palatal mucosa, we managed to reduce the amount of patients who required an orthognathic procedure. When this procedure was indicated, the surgical intervention was also greatly simplified.

Major burn surgery causes large hemorrhage and coagulation dysfunction. Treatment algorithms guided by ROTEM ® and factor VIIa reduce the need for blood products, but there is no evidence regarding factor XIII. Factor XIII deficiency changes clot stability and decreases wound healing. This study evaluates the efficacy and safety of factor XIII correction and its repercussion on transfusion requirements in burn surgery. Randomized retrospective study with 40 patients undergoing surgery at the Burn Unit, allocated into Group A those with factor XIII assessment (n = 20), and Group B, those without assessment (n = 20). Erythrocyte transfusion was guided by a hemoglobin trigger of 10g.dL -1 and the other blood products by routine coagulation and ROTEM ® tests. Analysis of blood product consumption included units of erythrocytes, fresh frozen plasma, platelets, and fibrinogen. The coagulation biomarker analysis compared the pre- and post-operative values. Group A (with factor XIII study) and Group B had identical total body surface area burned. All patients in Group A had a preoperative factor XIII deficiency, whose correction significantly reduced units of erythrocyte concentrate transfusion (1.95 vs. 4.05, p = 0.001). Pre- and post-operative coagulation biomarkers were similar between groups, revealing that routine coagulation tests did not identify factor XIII deficiency. There were no recorded thromboembolic events. Correction of factor XIII deficiency in burn surgery proved to be safe and effective for reducing perioperative transfusion of erythrocyte units.

Various adverse effects of homologous blood transfusion detected particularly in open heart surgery, in which it is frequently used, lead researchers to study on autologous blood use and to evaluate the patient's blood better. Due to the complications of homologous blood transfusion, development of techniques that utilize less transfusion has become inevitable. We aimed to evaluate the effects of acute normovolemic hemodilution (ANH) in patients undergoing open heart surgery. In this study, 120 patients who underwent open heart surgery were included. Patients were grouped into three: Autologous transfusion group (Group 1), homologous transfusion group (Group 2), and those received autologous blood and homologous blood products (Group 3). Patient data regarding preoperative characteristics, biochemical parameters, drainage, extubation time, duration of stay at intensive care, atrial fibrillation (AF) development, and hospital stay were recorded. A statistically significant difference ( P < 0.005) was found in favor of autologous group (Group 1) with respect to gender, body surface area, European System for Cardiac Operative Risk Evaluation, smoking, hematocrit levels, platelet counts, urea, C-reactive protein levels, protamine use, postoperative drainage, frequency of AF development, intubation period, stay at intensive care and hospital stay, and amount of used blood products. The use of autologous blood rather than homologous transfusion is not only attenuates side effects and complications of transfusion but also positively affects postoperative recovery process. Therefore, ANH can be considered as an easy, effective, and cheap technique during open heart surgery.

Anesthetic agents used for general anesthesia are emerging possible influential factors for surgical site infection (SSI). In this retrospective study, we evaluated the incidence of SSI after colorectal surgery according to the main anesthetic agents: volatile anesthetics vs. propofol. A total 1,934 adult patients, who underwent elective colorectal surgery under general anesthesia between January 2011 and December 2013, were surveyed to evaluate the incidence of SSI: 1,519 using volatile anesthetics and 415 using propofol for main anesthetic agents. Patient, surgery, and anesthesia-related factors were investigated from all patients. Propensity-score matching was performed to reduce the risk of confounding and produced 390 patients in each group. Within the propensity-score matched groups, the incidence of SSI was higher in the volatile group compared with the propofol group (10 [2.6%] vs. 2 [0.5%], OR = 5.0 [95% CI = 1.1-2.8]). C-reactive protein was higher in the volatile group than in the propofol group (8.4 ± 5.6 vs. 7.1 ± 5.3 mg/dl, P = 0.001), and postoperative white blood cells count was higher in the volatile group than in the propofol group (9.2 ± 3.2 × 10(3)/µl vs. 8.6 ± 3.4 × 10(3)/µl, P = 0.041). The results of this study suggest that intravenous anesthesia may have beneficial effects for reducing SSI in colorectal surgery compared to volatile anesthesia.

Introduction In this retrospective study, we aimed to determine the risk factors for coronary artery bypass surgery in patients under 45 years of age, and evaluate the early postoperative results and the effect of gender. Methods A total of 324 patients under 45 years of age who undergone on-pump coronary artery bypass surgery between April 12, 2004 and January 10, 2012 were included to the study. Patients divided into groups as follows: Group 1 consisted of 269 males (mean age 41.3), Group 2 consisted of 55 females (mean age 41.6). Preoperative risk factors, intraoperative and postoperative data and early mortality rates of the groups were compared. Results Smoking rate was significantly higher in Group 1. Diabetes mellitus incidence and body mass index were significantly higher in Group 2 (P values P=0.01; P=0.0001; P=0.04 respectively). The aortic cross-clamping and cardiopulmonary bypass time and number of grafts per patient were significantly higher in Group 1 (P values P=0.04; P=0.04; P=0.002 respectively). There were no deaths in either group. Conclusion We found that gender has no effect on early mortality rates of the coronary bypass surgery patients under 45 years. PMID:25714211

Heat Moisture Exchangers (HMEs) conserve heat and moisture during expiration and make this available to inspired gases during subsequent inspiration. We sought to evaluate the effectiveness of HMEs in the prevention of perioperative hypothermia in patients scheduled for abdominal surgery under general anaesthesia relaxant technique with endotrachael intubation (GART.) Lagos University Teaching Hospital, in Modular theatre, Anaesthesia unit. The study was a randomized, controlled, longitudinal, interventional study Methods: 100 ASA I, II and III patients aged 18 to 65 years scheduled for abdominal surgery under GART were randomly assigned to 2 groups, groups H and C. Group H had HMEs, while group C served as controls. Core temperature measured using tympanic probe was every 10 minutes till end of anaesthesia Data from total 99 patients, 49 in group H and 50 in group C were eventually analysed. Although patients in both groups developed hypothermia in the course of anaesthesia, core temperature was significantly lower p< 0.05 after one hour in the control group than the intervention group. The use of HMEs during general anaesthesia with endotrachael intubation did not prevent hypothermia but resulted in higher core temperature and should be part of a multimodal approach in the prevention of perioperative hypothermia.

Background: Thoracic spinal anesthesia has been used for laparoscopic cholecystectomy and abdominal surgeries, but not in breast surgery. The present study compared this technique with general anesthesia in breast cancer surgeries. Materials and Methods: Forty patients were enrolled in this comparative study with inclusion criteria of ASA physical status I-III, primary breast cancer without known extension beyond the breast and axillary nodes, scheduled for unilateral mastectomy with axillary dissection. They were randomly divided into two groups. The thoracic spinal group (S) (n = 20) underwent segmental thoracic spinal anesthesia with bupivacaine and fentanyl at T5-T6 interspace, while the other group (n = 20) underwent general anesthesia (G). Intraoperative hemodynamic parameters, intraoperative complications, postoperative discharge time from post-anesthesia care unit (PACU), postoperative pain and analgesic consumption, postoperative adverse effects, and patient satisfaction with the anesthetic techniques were recorded. Results: Intraoperative hypertension (20%) was more frequent in group (G), while hypotension and bradycardia (15%) were more frequent in the segmental thoracic spinal (S) group. Postoperative nausea (30%) and vomiting (40%) during PACU stay were more frequent in the (G) group. Postoperative discharge time from PACU was shorter in the (S) group (124 ± 38 min) than in the (G) group (212 ± 46 min). The quality of postoperative analgesia and analgesic consumption was better in the (S) group. Patient satisfaction was similar in both groups. Conclusions: Segmental thoracic spinal anesthesia has some advantages when compared with general anesthesia and can be considered as a sole anesthetic in breast cancer surgery with axillary lymph node clearance.

Lower deep venous thrombosis (DVT) is one of the major complications of patients with tumors or patients undergoing major surgery. Electrical acupoint stimulation, an established technique of traditional Chinese medicine (TCM), can be well combined with Western medicine to reduce the incidence of postoperative DVT, especially in elderly patients. The objectives of this study were to assess the efficiency of electrical acupoint stimulation in the prevention of postsurgery DVT in elderly patients with gastrointestinal malignant tumors and to validate an effective and safe nursing approach that integrates TCM and Western medicine. A total of 120 patients (none aged <60 years) who underwent malignant gastrointestinal tumor surgery between July 2005 and May 2007 were randomly divided into 3 groups: routine nursing group (group C1), graduated compression stockings group (group C2), and electrical acupoint stimulation group (group T). Hemorheological parameters (blood viscosity, etc) were measured and compared before and after surgery. Compared with groups C1 and C2, group T showed a significant difference in blood viscosity and blood flow velocity (P < .05). However, there were no statistical differences among groups C1, C2, and T in other hemorheological parameters. By speeding up the blood flow in patients' lower limbs, electrical acupoint stimulation showed a great potential to prevent symptomless DVT in elderly patients after malignant gastrointestinal tumor surgery. Western medical care combined with TCM can reduce the occurrence of lower DVT in elderly patients suffering from gastrointestinal cancer. This approach may help nurses to plan effective care for elderly patients.

The creation of an acute care surgery service provides a rich operative experience for acute care surgeons. Elective surgeons typically have concerns about whether their practice volume will be restored with elective cases. Acute care surgery has financial implications for both groups. The aim of this project is to examine the impact in terms of work relative value units (wRVUs), collections, and cases in both groups with creation of an acute care surgery service at our institution. Work RVUs, collections, and case volume were examined from departmental records for 2 groups before and after acute care surgery service creation. The service began on September 1, 2008. Before this time, emergency surgical consults went to the general surgeon on call. After this date, all emergency consults were seen by acute care surgeons. The number of operations performed by the acute care surgery group increased significantly when the mean of the 2 years after institution of acute care surgery were compared with the mean of the 2 years preceding the service creation (1,639 vs 790/year; p = 0.007). There was no change in total operations done by the elective surgery group (2,763 vs 2,496/year: p = 0.13). Elective caseload, however, did increase by 23% in the elective surgery group. In the acute care surgery group, wRVUs increased by 140% and elective surgery group wRVUs decreased by 8%. Collections increased in both groups (acute care surgery 129%, elective surgery 7%) and the combined collections of the groups increased by $2,138,00 in the year after service creation. Acute care surgery service creation took emergency business from the elective surgery group, but this was almost immediately replaced with elective cases. This resulted in higher collections for both groups and a resultant significant increase in collections in aggregate. Copyright © 2012 American College of Surgeons. Published by Elsevier Inc.

The therapeutic effects of vitamin K3 (VK3) on osteoporosis are still unknown. In this study, we hypothesized that VK3 possesses therapeutic effects on osteoporosis; to verify this hypothesis, the ovariectomized rat was used as an osteoporosis model. Fifty-six Sprague-Dawley female rats aged 8 to 9 months were randomly assigned to 4 groups: sham surgery, ovariectomy with saline, ovariectomy with low-dose VK3, and ovariectomy with high-dose VK3. Intramuscular injection of VK3 was performed every other day beginning 1 month postoperatively. The therapeutic effects of VK3 on osteoporosis were evaluated by measurement of bone mineral density (BMD), bone biochemical markers, biomechanical properties, and bone morphometric parameters. The overall average BMD in VK3-treated groups increased to a level between those of the ovariectomy group and the sham surgery group. The procollagen I N-terminal peptide level peaked at 2 months after surgery in all groups except in the group that had undergone ovariectomy with low-dose VK3. The tartrate-resistant acid phosphatase 5b level increased more slowly at 4 months after surgery than at 2 months after surgery in the VK3-treated groups. The ovariectomy with high-dose VK3 group had the highest maximum stress of the middle femur of all groups. With VK3 treatment, the trabecular bone area percentage increased. All morphometric indicators for the middle tibia in the VK3-treated groups reached the levels found in the sham surgery group. In summary, VK3 therapy increased BMD at 1 and 2 months postsurgery and the maximum stress of the middle femur. In addition, VK3 therapy slowed the increase in bone turnover in ovariectomized rats. Furthermore, VK3 can improve morphometric indicators for the middle tibia. Our preliminary study indicates that VK3 has a potential therapeutic effect on osteoporosis and is worthy of further investigation. Copyright © 2015 Elsevier Inc. All rights reserved.

Postoperative epidural analgesia for major upper abdominal and thoracic surgery can provide significant benefits, including superior analgesia and reduced pulmonary dysfunction. Nevertheless, epidural analgesia may also be associated with decreased muscle strength, sympathetic tone, and proprioception that could possibly contribute to falls. The purpose of this retrospective case-control study was to search a large national database in order to investigate the possible relationship between postoperative epidural analgesia and the rate of inpatient falls. Data from the nationwide inpatient sample for 2007-2011 were queried for adult patients who underwent elective major upper abdominal and thoracic surgery. Multiple International Classification of Diseases, Ninth Revision, Clinical Modification codes for inpatient falls and accidents were combined into one binary variable. Univariate analyses were used for initial statistical analysis. Logistic regression analyses and McNemar's tests were subsequently used to investigate the association of epidural analgesia with inpatient falls in a 1:1 case-control propensity-matched sample after adjustment of patients' demographics, comorbidities, and hospital characteristics. Forty-two thousand six hundred fifty-eight thoracic and 54,974 upper abdominal surgical procedures were identified. The overall incidence of inpatient falls in the thoracic surgery group was 6.54% with an increasing trend over the study period from 4.95% in 2007 to 8.11% in 2011 (P < 0.001). Similarly, the overall incidence of inpatient falls in the upper abdominal surgery group was 5.30% with an increasing trend from 4.55% in 2007 to 6.07% in 2011 (P < 0.001). Postoperative epidural analgesia was not associated with an increased risk for postoperative inpatient falls in the thoracic surgery group (relative risk [RR], 1.18; 95% confidence interval [CI], 0.95 to 1.47; P = 0.144) and in the upper abdominal surgery group (RR, 0.84; 95% CI 0.64 to 1.09; P = 0.220). Inpatient falls compared with non-falls were associated with a longer median (interquartile range) length of hospital stay in both the thoracic surgery group (11 [7-17] days vs 9 [6-16] days, respectively; P < 0.001) and the upper abdominal surgery group (12 [7-20] days vs 10 [6-17] days, respectively; P < 0.001). Our study suggests that postoperative epidural analgesia for patients undergoing major upper abdominal and thoracic surgery is not associated with an increased risk of inpatient falls.

Adolescent idiopathic scoliosis (AIS) surgery usually require prolonged operative times with extensive soft tissue dissection and significant perioperative blood loss, and allogeneic blood products are frequently needed. Methods to reduce the requirement for transfusion would have a beneficial effect on these patients. Although many previous studies have revealed the efficacy of tranexamic acid (TXA) in spinal surgery, there is still a lack of agreement concerning the reduction of both blood loss and transfusion requirements of large dose tranexamic acid (TXA) in surgery for adolescent idiopathic scoliosis (AIS). The objective of this study was to elevate the efficacy and safety of a large dose tranexamic acid (TXA) in reducing transfusion requirements of allogeneic blood products in adolescent idiopathic scoliosis (AIS) surgery using a retrospective study designed with historical control group. One hundred thirty seven consecutive AIS patients who underwent surgery treatment with posterior spinal pedicle systems from August 2011 to March 2015 in our scoliosis center were retrospectively reviewed. Patients were divided into two groups, the TXA group and the historical recruited no TXA group (NTXA). Preoperative demographics, radiographic parameters, operative parameters, estimated blood loss (EBL), total irrigation fluid, number of patients requiring blood transfusion, mean drop of Hb (Pre-op Hb-Post-op Hb), haematocrit pre and post-surgery, mean volume of blood transfusion, hospitalization time, and adverse effect were recorded and compared. All the patients were successfully treated with satisfied clinical and radiographic outcomes. There were 71 patients in the TXA group and 66 patients in the NTXA group. The preoperative demographics were homogeneity between two groups (P > 0.05). There were no significant difference in average operative time between two groups (209 min vs 215 min, p >0.05). Number of patients in the TXA group showed a significant decrease in transfusion requirements with an associated reduced intraoperative blood loss of nearly 45% compared with those in NTXA group (8 vs 37, 619 ml vs 1125 ml, P < 0.05). There were no significant difference in total irrigation fluid between two groups (540 vs 550, p >0.05). Additional, patients in NTXA group showed significant decrease of Hb compared with patients in TXA group (5.2 g/dL vs 3.3 g/dL, P < 0.05), No significant difference were found in hospitalization time between two groups (6.3 vs 7.2 days, P > 0.05). No minor adverse effects associated with use of TXA were noted. Use of large dose tranexamic acid routinely seems to be effective and safe in reducing allogenic blood transfusion and blood loss in adolescent idiopathic scoliosis surgery.

Despite the widespread adoption of endoscopic transsphenoidal surgery for pituitary adenomas, the sinonasal quality of life (QOL) and health status in patients who have undergone this technique have not been compared with these findings in patients who have undergone the traditional direct uninostril microsurgical technique. In this study, the authors compared the sinonasal QOL and patient-reported health status after use of these 2 surgical techniques. The study design was a nonblinded prospective cohort study. Adult patients with sellar pathology and planned transsphenoidal surgery were screened at 4 pituitary centers in the US between October 2011 and August 2013. The primary end point of the study was postoperative patient-reported sinonasal QOL as measured by the Anterior Skull Base Nasal Inventory-12 (ASK Nasal-12). Supplementary end points included patient-reported health status estimated by the 8-Item Short Form Health Survey (SF-8) and EuroQol (EQ)-5D-5L instruments, and sinonasal complications. Patients were followed for 6 months after surgery. A total of 301 patients were screened and 235 were enrolled in the study. Of these, 218 were analyzed (111 microsurgery patients, 107 endoscopic surgery patients). Demographic and tumor characteristics were similar between groups (p ≥ 0.12 for all comparisons). The most common complication in both groups was sinusitis (7% in the microsurgery group, 13% in the endoscopic surgery group; p = 0.15). Patients treated with the endoscopic technique were more likely to have postoperative nasal debridements (p < 0.001). The ASK Nasal-12 and SF-8 scores worsened substantially for both groups at 2 weeks after surgery, but then returned to baseline at 3 months. At 3 months after surgery, patients treated with endoscopy reported statistically better sinonasal QOL compared with patients treated using the microscopic technique (p = 0.02), but there were no significant differences at any of the other postoperative time points. This is the first multicenter study to examine the effect of the transsphenoidal surgical technique on sinonasal QOL and health status. The study showed that surgical technique did not significantly impact these patient-reported measures when performed at high-volume centers.

The study was to comprehensively compare the postoperative outcome and imaging parameter characters in a short/middle period between the percutaneous endoscopic lumbar discectomy (PELD) and the internal fixation of bone graft fusion (the most common form is posterior lumbar interbody fusion [PLIF]) for the treatment of adjacent segment lumbar disc prolapse with stable retrolisthesis after a previous lumbar internal fixation surgery.In this retrospective case-control study, we collected the medical records from 11 patients who received PELD operation (defined as PELD group) for and from 13 patients who received the internal fixation of bone graft fusion of lumbar posterior vertebral lamina decompression (defined as control group) for the treatment of the lumbar disc prolapse combined with stable retrolisthesis at Department of Spine Surgery, the Third Hospital of Hebei Medical University (Shijiazhuang, China) from May 2010 to December 2015. The operation time, the bleeding volume of perioperation, and the rehabilitation days of postoperation were compared between 2 groups. Before and after surgery at different time points, ODI, VAS index, and imaging parameters (including Taillard index, inter-vertebral height, sagittal dislocation, and forward bending angle of lumbar vertebrae) were compared.The average operation time, the blooding volume, and the rehabilitation days of postoperation were significantly less in PELD than in control group. The ODI and VAS index in PELD group showed a significantly immediate improving on the same day after the surgery. However, Taillard index, intervertebral height, sagittal dislocation in control group showed an immediate improving after surgery, but no changes in PELD group till 12-month after surgery. The forward bending angle of lumbar vertebrae was significantly increased and decreased in PELD and in control group, respectively.PELD operation was superior in terms of operation time, bleeding volume, recovery period, and financial support, if compared with lumbar internal fixation operation. Radiographic parameters reflect lumber structure changes, which could be observed immediately after surgery in both methods; however, the recoveries on nerve function and pain relief required a longer time, especially after PLIF operation.

To study the effectiveness of relaxation hypnosis in outpatient cataract surgery. Prospective study of 171 patients undergoing cataract surgery under hypnosis, performed by the same nurse anesthetist. The procedures were performed by 2 senior surgeons, A and B (A=78 surgeries, and B=93 surgeries) under topical anesthesia and with a 2.2-mm mini-incision. The hypnosis group (n=102) was compared to a control group (n=69) according to quantitative, objective criteria: hemodynamic changes and the need for intravenous medication in operating room, as well as subjective, qualitative criteria: surgical comfort, effectiveness of hypnosis, and patient satisfaction. Subgroup analyses by surgeon, 1st and 2nd eye surgery, were performed. Hemodynamic parameters were not significantly different between the 2 groups: systolic blood pressure (P=0.06) and maximum heart rate (P=0.25). However, the use of intraoperative intravenous medication was significantly higher in the control group (49.3% versus 21.6%, P<0.001). The effectiveness of relaxation was scored at a mean of 5.25/6 by the nurse anesthetist. The patients in the hypnosis group reported a mean comfort rating of 8.4/10, and 100% were satisfied with this hypnosis experience. Preliminary results of this study are very positive for all three parties: patient/anesthetist/surgeon. They are leading to an expanded university training program for operating room personnel in order to improve quality of care and reduce premedication in elderly patients so as to facilitate their return to home.

Background. Parasternal block and transcutaneous electrical nerve stimulation (TENS) have been demonstrated to produce effective analgesia and reduce postoperative opioid requirements in patients undergoing cardiac surgery. Objectives. To compare the effectiveness of TENS and parasternal block on early postoperative pain after cardiac surgery. Methods. One hundred twenty patients undergoing cardiac surgery were enrolled in the present randomized, controlled prospective study. Patients were assigned to three treatment groups: parasternal block, intermittent TENS application, or a control group. Results. Pain scores recorded 4 h, 5 h, 6 h, 7 h, and 8 h postoperatively were lower in the parasternal block group than in the TENS and control groups. Total morphine consumption was also lower in the parasternal block group than in the TENS and control groups. It was also significantly lower in the TENS group than in the control group. There were no statistical differences among the groups regarding the extubation time, rescue analgesic medication, length of intensive care unit stay, or length of hospital stay. Conclusions. Parasternal block was more effective than TENS in the management of early postoperative pain and the reduction of opioid requirements in patients who underwent cardiac surgery through median sternotomy. This trial is registered with Clinicaltrials.gov number NCT02725229. PMID:27445610

During the past decade, it has become increasingly more common to offer hip arthroscopic surgery when treating people with femoroacetabular impingement (FAI). Nevertheless, the latest reviews conclude that it still remains to be properly investigated how surgery affects the patients. Specifically, detailed information on the functional, muscular and mechanical impact of surgery in larger groups is lacking. Furthermore, the long-term outcome of the surgery is still to be investigated. In this prospective cohort study, a total of 60 patients with FAI scheduled for arthroscopic surgery will be followed and tested preoperatively, and again after 3, 6, 9 and 12 months. Assessment includes isokinetic dynamometry evaluating hip flexion and extension; evaluation of functional capacity in a three-dimensional motion laboratory; pain assessment; self-reported function, quality of life, expectation and satisfaction with the surgery; recording of previous and present sporting activities and accelerometry. In addition, data on surgical procedure, rehabilitation progress, adverse events and failure will be recorded. Patients will be compared with an age-matched and gender-matched reference group of 30 persons with no hip, knee, ankle or back problems. Long-term follow-up of this cohort may evaluate possible reoperations and development of hip osteoarthritis. Furthermore, analysis on how subgroups respond to the treatment could be performed together with identification of possible "non-responders". The study is approved by the Central Denmark Region Committee on Biomedical Research Ethics (Journal No 1-10-72-239-14). The results from this study will be presented at national and international congresses and published in peer-reviewed journals. NCT02306525. Published by the BMJ Publishing Group Limited.

Enhanced recovery after surgery (ERAS) programs have been shown to ease the postoperative recovery and improve clinical outcomes for various surgery types. ERAS cost-effectiveness was demonstrated for colorectal surgery but not for liver surgery. The present study aim was to analyze the implementation costs and benefits of a specific ERAS program in liver surgery. A dedicated ERAS protocol for liver surgery was implemented in our department in July 2013. The subsequent year all consecutive patients undergoing liver surgery were treated according to this protocol (ERAS group). They were compared in terms of real in-hospital costs with a patient series before ERAS implementation (pre-ERAS group). Mean costs per patient were compared with a bootstrap T test. A cost-minimization analysis was performed. Seventy-four ERAS patients were compared with 100 pre-ERAS patients. There were no significant pre- and intraoperative differences between the two groups, except for the laparoscopy number (n = 18 ERAS, n = 9 pre-ERAS, p = 0.010). Overall postoperative complications were observed in 36 (49 %) and 64 patients (64 %) in the ERAS and pre-ERAS groups, respectively (p = 0.046). The median length of stay was significantly shorter for the ERAS group (8 vs. 10 days, p = 0.006). The total mean costs per patient were €38,726 and €42,356 for ERAS and pre-ERAS (p = 0.467). The cost-minimization analysis showed a total mean cost reduction of €3080 per patient after ERAS implementation. ERAS implementation for liver surgery induced a non-significant decrease in cost compared to standard care. Significant decreased complication rate and hospital stay were observed in the ERAS group.

The Singapore General Hospital Burns Protocol was implemented in May 2014 to standardize treatment for all burns patients, incorporate new techniques and materials, and streamline the processes and workflow of burns management. This study aims to analyze the effects of the Burns Protocol 2 years after its implementation. Using a REDCap electronic database, all burns patients admitted from May 2013 to April 2016 were included in the study. The historical preimplementation control group composed of patients admitted from May 2013 to April 2014 (n = 96). The postimplementation prospective study cohort consisted of patients admitted from May 2014 to April 2016 (n = 243). Details of the patients collected included age, sex, comorbidities, total body surface area (TBSA) burns, time until surgery, number of surgeries, number of positive tissue and blood cultures, and length of hospital stay. There was no statistically significant difference in the demographics of both groups. The study group had a statistically significant shorter time to surgery compared with the control group (20.8 vs 38.1, P < 0.0001). The study group also averaged fewer surgeries performed (1.96 vs 2.29, P = 0.285), which, after accounting for the extent of burns, was statistically significant (number of surgeries/TBSA, 0.324 vs 0.506; P = 0.0499). The study group also had significantly shorter length of stay (12.5 vs 16.8, P = 0.0273), a shorter length of stay/TBSA burns (0.874 vs 1.342, P = 0.0101), and fewer positive tissue cultures (0.6 vs 1.3, P = 0.0003). The study group also trended toward fewer positive blood culture results (0.09 vs 0.35, P = 0.0593), although the difference was just shy of statistical significance. The new Singapore General Hospital Burns Protocol had revolutionized Singapore burns care by introducing a streamlined, multidisciplinary burns management, resulting in improved patient outcomes, lowered health care costs, and improved system resource use.

Having poor sleep quality is common among patients following cardiopulmonary artery bypass graft surgery. Pain, stress, anxiety and poor sleep quality may be improved by massage therapy. This study evaluated whether massage therapy is an effective technique for improving sleep quality in patients following cardiopulmonary artery bypass graft surgery. Participants included cardiopulmonary artery bypass graft surgery patients who were randomized into a control group and a massage therapy group following discharge from the intensive care unit (Day 0), during the postoperative period. The control group and the massage therapy group comprised participants who were subjected to three nights without massage and three nights with massage therapy, respectively. The patients were evaluated on the following mornings (i.e., Day 1 to Day 3) using a visual analogue scale for pain in the chest, back and shoulders, in addition to fatigue and sleep. Participants kept a sleep diary during the study period. Fifty-seven cardiopulmonary artery bypass graft surgery patients were enrolled in the study during the preoperative period, 17 of whom were excluded due to postoperative complications. The remaining 40 participants (male: 67.5%, age: 61.9 years ± 8.9 years, body mass index: 27.2 kg/m² ± 3.7 kg/m²) were randomized into control (n = 20) and massage therapy (n = 20) groups. Pain in the chest, shoulders, and back decreased significantly in both groups from Day 1 to Day 3. The participants in the massage therapy group had fewer complaints of fatigue on Day 1 (p=0.006) and Day 2 (p=0.028) in addition, they reported a more effective sleep during all three days (p=0.019) when compared with the participants in the control group. Massage therapy is an effective technique for improving patient recovery from cardiopulmonary artery bypass graft surgery because it reduces fatigue and improves sleep.

Management of diseases of the descending thoracic aorta is trending from open surgery toward thoracic endovascular aortic repair (TEVAR), because TEVAR is reportedly associated with less perioperative mortality. However, comparisons between TEVAR and open surgery, adjusting for patient comorbidities, have not been well studied. In this nationwide population-based study, we compared the outcomes between TEVAR and open surgery in type B aortic dissection. From 2003 to 2009, data on patients with type B aortic dissection who underwent either open surgery or TEVAR were obtained from the National Health Insurance Research Database. Survival, length of stay, and complications were compared between TEVAR and open repair. To minimize possible bias, we performed an additional analysis after matching patients by age, sex, and propensity score. A total of 1661 patients were identified, of whom 1542 underwent open repair and 119 TEVAR. Patients in the TEVAR group were older (63.0 ± 15.4 years vs. 58.1 ± 13.1 years; p = 0.001), included more males, and had more preoperative comorbidities. Thirty-day mortality in the TEVAR group was significantly lower than that in the open repair group (4.2% vs. 17.8%; p < 0.001). The midterm survival rates in the unmatched cohort between the open surgery and TEVAR groups at 1 year, 2 years, 3 years, and 4 years were 76%, 73%, 71%, and 68% vs. 92%, 86%, 82%, and 79%, respectively. The length of stay in the TEVAR group was shorter than that in the open repair group (p = 0.001). The TEVAR group had less respiratory failure (p = 0.022) and fewer wound complications than the open repair group (p = 0.008). The matched cohort showed similar results. TEVAR for type B aortic dissection repair has less perioperative mortality, a shorter length of hospitalization, a higher midterm survival rate, less postoperative respiratory failure, and fewer wound complications than open surgery.

Abstract Background: Breast reduction surgery is a common cosmetic surgery with a high incidence of blood loss and transfusion. In this surgery, the reduction of blood loss related to surgical manipulation and the volume of resected tissue is a target. In the present study, we compared the effects of esmolol-induced controlled hypotension on surgical visibility, surgical bleeding, and the duration of surgery in patients anesthetized with propofol/remifentanil (PR) or sevoflurane/remifentanil (SR). Methods: Patients in the American Society of Anesthesiologists I/II risk group undergoing breast reduction surgery were prospectively randomized into PR (n = 25) and SR (n = 25) groups. Controlled hypotension was induced with esmolol in both groups. During the intraoperative period, the heart rate (HR), mean arterial pressure (MAP), operation duration, volume of intraoperative blood loss, volume of blood received through postoperative drains, volume of resected tissues, and surgical area bleeding score were recorded. Results: The duration of operation in the incisional period was shorter in group PR compared to group SR (P = 0.04). The change in HR was lower in incision and hemostasis periods in the group PR compared to the group SR (P < 0.001). Total intraoperative intraoperative bleeding volume and volume of blood received through drains on postoperative postoperative day 1, day 2, and in total were found to be significantly lower in group PR compared to group SR. Surgical visibility scoring was more effective in group PR compared to SR. Conclusion: In the breast reduction surgery performed under esmolol-induced controlled hypotension, the effect of propofol + remifentanil anesthesia on the duration of incisional surgery, surgical visibility, and volume of surgical blood loss was more reliable and effective compared to that of sevoflurane + remifentanil, which seems to be an advantage.

Systemic inflammation is involved in the development of acute kidney injury (AKI) after cardiac surgery with cardiopulmonary bypass (CPB). Ulinastatin, a urinary trypsin inhibitor (UTI), possesses a variety of anti-inflammatory effects. Therefore, we hypothesized that the administration of ulinastatin would reduce the occurrence of AKI in patients undergoing cardiac surgery with CPB. A retrospective propensity score matched analysis was used to evaluate the effect of ulinastatin on the development of AKI in patients undergoing first documented cardiac surgery with CPB between January 2008 and December 2012 in our hospital. Multiple logistic regression models were also employed to identify the association between UTI administration and development of AKI. A total of 2072 patients who underwent cardiac surgery with CPB met the inclusion criteria. Before propensity score matching, variables such as age, baseline creatinine, CPB duration, red blood cells transfused, and hematocrit were statistically different between the ulinastatin (UTI) group and the control group. On the basis of propensity scores, 409 UTI patients were successfully matched to the 409 patients from among those 1663 patients without UTI administration. After propensity score matching, no statistically significant differences in the baseline characteristics were found between the UTI group and the control group. The propensity score matched cohort analysis revealed that AKI and the need for renal replacement therapy occurred more frequently in the control group than in the UTI group (40.83% vs. 30.32%, P = 0.002; 2.44% vs. 0.49%, P = 0.02, respectively). However, there were no significant differences in mortality, length of intensive care unit stay, and length of hospital stay between the UTI group and the control group. Using multivariate logistic regression analysis, we found ulinastatin played a protective role in the development of AKI after cardiac surgery (odds ratio 0.71, 95% confidence interval 0.56-0.90, P = 0.005). This study shows that ulinastatin was associated with a lower incidence of AKI after cardiac surgery, suggesting that the administration of ulinastatin may be favorable for those patients undergoing cardiac surgery with CPB.

Retrospective comparative cohort study. Examine the impact of multilevel fusion on return to work (RTW) status and compare RTW status after multi- versus single-level cervical fusion for patients with work-related injury. Patients with work-related injuries in the workers' compensation systems have less favorable surgical outcomes. Cervical fusion provides a greater than 90% likelihood of relieving radiculopathy and stabilizing or improving myelopathy. However, more levels fused at index surgery are reportedly associated with poorer surgical outcomes than single-level fusion. Data was collected from the Ohio Bureau of Workers' Compensation (BWC) between 1993 and 2011. The study population included patients who underwent cervical fusion for radiculopathy. Two groups were constructed (multilevel fusion [MLF] vs. single-level fusion [SLF]). Outcomes measures evaluated were: RTW criteria, RTW <1year, reoperation, surgical complication, disability, and legal litigation after surgery. After accounting for a number of independent variables in the regression model, multilevel fusion was a negative predictor of successful RTW status within 3-year follow-up after surgery (OR = 0.82, 95% CI: 0.70-0.95, P <0.05).RTW criteria were met 62.9% of SLF group compared with 54.8% of MLF group. The odds of having a stable RTW for MLF patients were 0.71% compared with the SLF patients (95% CI: 0.61-0.83; P: 0.0001).At 1 year after surgery, RTW rate was 53.1% for the SLF group compared with 43.7% for the MLF group. The odds of RTW within 1 year after surgery for the MLF group were 0.69% compared with SLF patients (95% CI: 0.59-0.80; P: 0.0001).Higher rate of disability after surgery was observed in the MLF group compared with the SLF group (P: 0.0001) CONCLUSION.: Multilevel cervical fusion for radiculopathy was associated with poor return to work profile after surgery. Multilevel cervical fusion was associated with lower RTW rates, less likelihood of achieving stable return to work, and higher rate of disability after surgery. 3.

The aim of this study was to investigate the effect of listening to personal choice of music on self-report of pain intensity and the physiologic parameters in patients who have undergone open heart surgery. The study design was quasiexperimental. Patients were selected through convenience sampling in the Cardiovascular Surgery Intensive Care Unit at a university hospital. The study was conducted with a total of 87 patients who underwent open heart surgery: 44 in the music group, 43 in the control group, ages between 18 and 78 years. Through pretest-posttest design, postoperative first-day data were collected. First, physiologic parameters (blood pressure, heart rate, oxygen saturation, and respiratory rate) were recorded and a unidimensional verbal pain intensity scale applied to all participants. Later, the control group had a rest in their beds while the music group listened to their choice of music for 30 minutes. Physiologic data were then collected and the pain intensity scale applied once more. In the music group, there was a statistically significant increase in oxygen saturation (p = .001) and a lower pain score (p = .001) than in the control group. There was no difference between the groups in the other physiologic parameters. Results of this research provide evidence to support the use of music. Music might be a simple, safe, and effective method of reducing potentially harmful physiologic responses arising from pain in patients after open heart surgery.

Investigate if quality of life (QOL) normalizes on long-term follow-up after surgery for partial epilepsy in children. This is a cohort study with controls in which a consecutive cohort of nineteen 2-14-year-old children who underwent focal resections for intractable partial seizures between 1996 and 2006, were matched with 19 non-surgery intractable partial epilepsy patients, and with 19 healthy subjects. The two epilepsy groups were matched for age, sex, socio-economic status (SES), cognitive level, seizure type, and seizure frequency. The healthy group was matched with the two epilepsy groups for age, sex, SES, and cognitive level. QOL was assessed using the QOLCE (Quality of Life in Childhood Epilepsy Questionnaire). In the surgery group (follow-up 3.84+/-2.26 years), 78.9% had Engel class-I versus 21.1% in non-surgery (p=0.01) (follow-up 3.44+/-2.95 years). Surgery patients were similar to healthy subjects in the social, emotional, cognitive, behavioral, and overall QOL (p>0.05) but had lower scores in the total QOL, physical, and health domains (p<0.05). Surgery patients scored better than non-surgery in the behavioral domain and the HASES (Hague Side Effects Scale) score (p<0.05). Non-surgery patients scored worse than healthy in total QOL, physical, behavioral, health, and overall QOL (p<0.05). IQ, HASS (Hague Seizure Severity Scale), and HASES scores were positively associated with total QOL score (p<0.05). Subgroup analysis on seizure-free surgery patients showed that they did not differ from healthy subjects in any of QOL domains (p>0.05, power>0.8). Our data indicate that epilepsy surgery for partial seizures in children is associated with better QOL as compared to children with intractable epilepsy who are not operated on, and suggest that in those who achieve seizure freedom normal QOL may at least potentially be possible.

Abnormal pretreatment flexion-relaxation in chronic disabling occupational lumbar spinal disorder patients has been shown to improve with functional restoration rehabilitation. Little is known about the effects of prior lumbar surgeries on flexion-relaxation and its responsiveness to treatment. To quantify the effect of prior lumbar surgeries on the flexion-relaxation phenomenon and its responsiveness to rehabilitative treatment. A prospective cohort study of chronic disabling occupational lumbar spinal disorder patients, including those with and without prior lumbar spinal surgeries. A sample of 126 chronic disabling occupational lumbar spinal disorder patients with prior work-related injuries entered an interdisciplinary functional restoration program and agreed to enroll in this study. Fifty-seven patients had undergone surgical decompression or discectomy (n=32) or lumbar fusion (n=25), and the rest had no history of prior injury-related spine surgery (n=69). At post-treatment, 116 patients were reevaluated, including those with prior decompressions or discectomies (n=30), lumbar fusions (n=21), and no surgery (n=65). A comparison group of 30 pain-free control subjects was tested with an identical assessment protocol, and compared with post-rehabilitation outcomes. Mean surface electromyography (SEMG) at maximum voluntary flexion; subject achievement of flexion-relaxation (SEMG≤3.5 μV); gross lumbar, true lumbar, and pelvic flexion ROM; and a pain visual analog scale self-report during forward bending task. Identical measures were obtained at pretreatment and post-treatment. Patients entered an interdisciplinary functional restoration program, including a quantitatively directed, medically supervised exercise process and a multimodal psychosocial disability management component. The functional restoration program was accompanied by a SEMG-assisted stretching training program, designed to teach relaxation of the lumbar musculature during end-range flexion, thereby improving or normalizing flexion-relaxation and increasing lumbar flexion ROM. At 1 year after discharge from the program, a structured interview was used to obtain socioeconomic outcomes. At pre-rehabilitation, the no surgery group patients demonstrated significantly better performance than both surgery groups on absolute SEMG at maximum voluntary flexion and on true lumbar flexion ROM. Both surgery groups were less likely to achieve flexion-relaxation than the no surgery patients. The fusion patients had reduced gross lumbar flexion ROM and greater pain during bending compared with the no surgery patients, and reduced true lumbar flexion ROM compared with the discectomy patients. At post-rehabilitation, all groups improved substantially on all measures. When post-rehabilitation measures were compared with the pain-free control group, with gross and true lumbar ROM corrected by 8° per spinal segment fused, there were no differences between any of the patient groups and the pain-free control subjects on spinal ROM and only small differences in SEMG. The three groups had comparable socioeconomic outcomes at 1 year post-treatment in work retention, health-care utilization, new injury, and new surgery. Despite the fact that the patients with prior surgery demonstrated greater pretreatment SEMG and ROM deficits, functional restoration treatment, combined with SEMG-assisted stretching training, was successful in improving all these measures by post-treatment. After treatment, both groups demonstrated ROM within anticipated limits, and the majority of patients in all three groups successfully achieved flexion-relaxation. In a chronic disabling occupational lumbar spinal disorder cohort, surgery patients were nearly equal to nonoperated patients in responding to interdisciplinary functional restoration rehabilitation on measures investigated in this study, achieving close to normal performance measures associated with pain-free controls. The responsiveness and final scores shown in this study suggests that flexion-relaxation may be a useful, objective diagnostic tool to measure changes in physical capacity for chronic disabling occupational lumbar spinal disorder patients.

Harmonic instruments are an alternative tool for surgical dissection. The aim of this study is to evaluate differences in clinical outcomes relating to harmonic dissection when compared with electrocautery in patients undergoing major breast surgery in a regional centre over a 3-year period. Retrospective chart analysis was conducted of 52 patients undergoing major breast surgery for carcinoma or ductal carcinoma in situ by a single surgeon in a regional centre from May 2008 to January 2011. Analysis involved the extraction of qualitative data relating to patient demographics, surgery type and specimen histopathology. Quantitative data were extracted relating to duration of surgery, duration of patient-controlled analgesia (PCA) use, length of hospital admission, drainage output and presence of infection, haematoma or seroma. Fifty-two patients underwent major breast surgery; harmonic dissection n = 32 and electrocautery n = 20. The two groups were comparable. There was no significant difference identified relating the outcome measures. The median operative duration was shorter in the harmonic dissection group, however, was not of statistical significance. No significant difference was identified between groups relating to length of inpatient stay, duration of PCA use and total volume wound drainage and total days of drainage. Incidence of seroma and infection in the groups was not significantly different. The harmonic dissection is safe and effective in major breast surgery. The study did not demonstrate any clinical advantage from the use of harmonic dissection in major breast surgery compared with electrocautery, nor was there any difference in the complication rates measured. © 2014 Royal Australasian College of Surgeons.

  To evaluate waiting times for first-eye cataract surgery in Sweden following widespread adoption of the Nationell Indikationsmodell for Kataraktextraktion (NIKE) tool for prioritizing patients for cataract surgery.   Waiting times for all first-eye cataract surgeries in Sweden in 2009-2011 were identified from the Swedish National Cataract Register. Waiting times were compared according to demographic, clinical and NIKE indication group for surgery. Multivariate logistic regression modelling was used to determine factors associated with waiting times less than the 3-month Government guarantee period.   There were 141,070 first-eye cataract surgeries in 2009 to 2011; an annual increase of around 6%. Over the study period, mean waiting times decreased across all NIKE groups. The proportion waiting <3 months for surgery also increased across all NIKE groups. Surgery within 3 months of waitlisting was more likely for patients with a NIKE 1 indication classification (most need for surgery), in later years, male patients, younger patients and patients with a preoperative visual acuity in the better eye worse than 6/24.   Prioritizing patients for cataract surgery using NIKE reduces waiting times for those with the greatest need. © 2013 Acta Ophthalmologica Scandinavica Foundation.

Callosotomy can reveal hidden primary epileptogenic areas in Lennox-Gastaut syndrome (LGS). We studied the significance of causal connectivity for identifying hidden epileptogenic areas in preoperative electroencephalography (EEG) and for making a decision regarding resective surgery. We enrolled 18 LGS patients who underwent corpus callosotomy. Eight patients with unilateral epileptogenicity on post-callosotomy EEG underwent resective surgery (group A). Ten patients with independent bilateral epileptogenicity did not undergo resective surgery (group B). We analyzed generalized epileptiform discharges on pre-callosotomy EEG via direct directed transfer function (dDTF) and partial directed coherence (PDC). All regions exhibiting unilaterality in group A and bilaterality identified by dDTF or PDC in group B were concordant with the lateralization of the irritative zone on post-callosotomy EEG and with the localization of the resective areas, except for one patient in group A. The regions identified by dDTF exhibited high concordance rates with the resective areas in patients with good outcomes. Causal connectivity methods showed good concordance with hidden epileptogenic areas, and its concordance was associated with the prognosis of surgical outcome. This study provides evidence that causal connectivity methods can be helpful in deciding which type of surgery will be suitable for an LGS patient.

Prospective study. The purpose of this study was to compare the long-term clinical and radiologic outcomes of hybrid surgery (HS) and 2-level anterior cervical discectomy and fusion (2-ACDF) in patients with 2-level cervical disk disease. In a previous study with a 2-year follow-up, HS was shown to be superior to 2-ACDF, with a better Neck Disability Index (NDI) score, less postoperative neck pain, faster C2-C7 range of motion (ROM) recovery, and less adjacent ROM increase. Between 2004 and 2006, 40 patients undergoing 2-level cervical disk surgery at our hospital were identified as 2-level degenerative disk disease. Forty patients were included in the previous study; 35 patients were followed up for 5 years. Patients completed the NDI and graded their pain intensity before surgery and at routine postoperative until 5 years. Dynamic cervical radiographs were obtained before surgery and at routine postoperative intervals and the angular ROM for C2-C7 and adjacent segments was measured. The HS group had better NDI recovery until 3 years after surgery (P<0.05). Postoperative neck pain was lower in the HS group at 1 and 3 years after surgery (P<0.05), but arm pain relief was not differently relieved. The HS group showed more angular ROM for C2-C7 at 2 and 3 years after surgery. The superior adjacent segment ROM showed hypermobility in the 2-ACDF group and hypomobility in the HS group at all follow-up periods without statistically significance, but the inferior adjacent segment ROM differed significantly (P<0.05). HS is superior to 2-ACDF; it leads to better NDI recovery, less postoperative neck pain, faster C2-C7 ROM recovery, and less adjacent ROM increase over a 2-year follow-up, but these benefits of HS become similar to those of 2-ACDF with 5 years of follow-up.

Previous research has demonstrated the efficacy of using local compression to reduce postoperative pain after third molar surgery. It has been theorized that compression reduces pain intensity through vasoconstriction. The current research tests the veracity of this vasoconstriction hypothesis by testing the impact of local epinephrine (a local vasoconstrictor) versus a control on patients' pain ratings over 7 days following surgery. Fifty patients scheduled for mandibular third molar surgery were randomly assigned to receive one cartridge of Ultracaine DS Forte (the treatment group) or one cartridge of Ultracaine DS (the control group) after surgical removal of the third molar. Participants used the visual analog scale (VAS) to provide daily ratings of pain intensity for 7 days following surgery. In addition, on day 7, the perceived effectiveness of the pain treatment was measured with the global perceived effect (GPE) scale. A quality- of-life questionnaire was also completed. A repeated-measures ANOVA indicated that the treatment group perceived significantly less pain than the control group on days 2 to 7 following surgery. In addition, 77.8% of the treatment group perceived their pain treatment to be successful, while only 69.6% of the control group reported that their pain was reduced successfully by day 7. The results of this study provide an initial proof of concept that epinephrine may have an analgesic effect on the period following third molar surgery. Further research with larger sample sizes is needed to strengthen evidence for the clinical utility of offering localized epinephrine to patients following third molar surgery.

Vaginal pessaries, pelvic floor exercises and surgery are treatment options for women with symptomatic pelvic organ prolapse (POP). The aim of this study was to compare the outcomes of pessaries and surgery in women with symptomatic POP using the validated International Consultation on Incontinence Questionnaire-Vaginal Symptoms (ICIQ-VS) and Urinary Incontinence (ICIQ-UI) Short Form (SF). Women attending the Urogynecology clinics with symptomatic POP were recruited. All women were treated using either a vaginal pessary or surgery. Outcomes were evaluated and then compared at 1 year using the validated ICIQ-VS and ICIQ-UI (SF) questionnaires. A total of 287 women with symptomatic prolapse were recruited. 269 women completed the questionnaires at baseline and 183 at 1 year. At 1 year, improvement was noted in quality of life (QOL), frequency of urinary leak and vaginal symptoms in both groups except for the symptom of vaginal soreness in the pessary group and the symptom of a tight vagina in the surgery group. However, both these symptoms were not bothersome. Women who underwent surgery demonstrated an improvement in faecal evacuation and sex life. There was an overall statistically significant improvement in vaginal, sex, QOL and urinary symptom scores in both groups. No statistically significant difference was noted between the surgery and the pessary groups. Using validated questionnaires 1 year after treatment, women with symptomatic POP report improvement in vaginal, bowel, urinary and quality of life scores when treated with either pessary use or surgery. No statistically significant difference was noted in the two groups.

The use of self-expanding metal stents as a bridge to surgery in the setting of malignant colorectal obstruction has been advocated as an acceptable alternative to emergency surgery. However, concerns about the safety of stenting have been raised following recent randomized studies. The aim of the current study was to compare outcomes. This was an observational, comparative study. This study was conducted at a tertiary referral center and university teaching hospital. Patients with malignant colonic obstruction (n = 49) treated by either emergency surgery (n = 26) or with stent placement (n = 23) as a bridge to surgery were identified and followed. Short-term outcomes including stoma rates and postoperative morbidity and medium-term oncological outcomes were compared based on an "intention-to-treat" analysis. Patients in both groups were well matched on clinicopathological parameters. Technical and clinical successful stent deployment was achieved in 91% and 83%. This did not adversely impact cancer-specific and overall survival (log rank = nonsignificant). No difference was observed in stoma rates, primary anastomosis rates, perioperative mortality rates, or reoperation rates between the 2 groups. Significantly fewer patients underwent total colectomy in the stent group in comparison with the emergency surgery group (1/23 vs 6/26: p = 0.027). There was no difference in postoperative morbidity (59% vs 66%: p = 0.09). There was a significant reduction in readmission rates in the stent group (5/26 vs 0/23: p = 0.038). The small sample size of this study could lead to type II error. In addition, the study was nonrandomized and demonstrated a limited length of follow-up. Despite a high rate of technical and clinical success in selected patients with colonic obstruction, stenting has no impact on stoma rates. Despite concerns about the rate of stent-associated perforation, stenting does not adversely impact disease progression or survival. Future comparative trials are essential to better define the role of stenting in this setting and to ensure that we are not using costly technology to create an elective operative situation without concomitant patient benefits.

This study aims to explore the effects of tranexamic acid on the coagulation indexes of patients undergoing heart valve replacement surgery under the condition of cardiopulmonary bypass (CPB). One hundred patients who conformed to the inclusive criteria were selected and divided into a tranexamic acid group and a non-tranexamic acid group. They all underwent heart valve replacement surgery under CPB. Patients in the tranexamic acid group were intravenously injected with 1 g of tranexamic acid (100 mL) at the time point after anesthesia induction and before skin incision and at the time point after the neutralization of heparin. Patients in the non-tranexamic acid group were given 100 mL of normal saline at corresponding time points, respectively. Then the coagulation indexes of the two groups were analyzed. The activated blood clotting time (ACT) of the two groups was within normal scope before CPB, while four coagulation indexes including prothrombin time (PT), activated partial thromboplastin time (APTT), international normalized ratio (INR), and fibrinogen (FIB) had significant increases after surgery; the PT and INR of the tranexamic acid group had a remarkable decline after surgery. All the findings suggest that the application of tranexamic acid in heart valve replacement surgery under CPB can effectively reduce intraoperative and postoperative blood loss. © The Author(s) 2016.

The purpose of this study was to evaluate the effect of intraoperative dexmedetomidine sedation on patient's and surgeon's satisfaction during retinal surgery under sub-tenon's anesthesia. Forty-four patients scheduled for elective retinal surgery under sub-tenon's anesthesia were enrolled in this randomized controlled trial. The patients were divided into Dexmedetomidine (n = 22) and Control (n = 22) groups. Intravenous dexmedetomidine or 0.9% saline via infusion pump were administered continuously to the dexmedetomidine or control group, respectively. Ramsay sedation scale with a target level of 3-4 was used to assess adequacy of sedation. Perioperative pain, hemodynamic and respiratory data were collected, while satisfaction from patients and surgeon were assessed post-surgery using a 5-point satisfaction scale. Patient and surgeon satisfaction was higher in the dexmedetomidine group (P < 0.001, P = 0.002, respectively). The pain associated with sub-tenon's anesthesia and peripheral vitrectomy was lesser in the dexmedetomidine group than in the control group (P = 0.020). There was significant reduction of heart rate in the dexmedetomidine group (P = 0.001), but only one patient needed treatment with atropine. There was no respiratory effect on both groups. Dexmedetomidine sedation during retinal surgery improved satisfaction from both patient and surgeon without respiratory complication. It is a safe and preferable choice of sedation for retinal surgery.

To compare long-term results of radiotherapy alone versus radiotherapy followed by exenteration of the nasal cavity in dogs with malignant intranasal neoplasia. Retrospective study. 53 dogs with malignant intranasal neoplasia. All dogs underwent radiotherapy consisting of administration of 10 fractions of 4.2 Gy each on consecutive weekdays. For dogs in the surgery group (n=13), follow-up computed tomography was performed, and dogs were scheduled for surgery if persistent or recurrent tumor was seen. Perioperative complications for dogs that underwent surgery included hemorrhage requiring transfusion (2 dogs) and subcutaneous emphysema (8). Rhinitis and osteomyelitis-osteonecrosis occurred significantly more frequently in dogs in the radiotherapy and surgery group (9 and 4 dogs, respectively) than in dogs in the radiotherapy-only group (4 and 3 dogs, respectively). Two- and 3-year survival rates were 44% and 24%, respectively, for dogs in the radiotherapy group and 69% and 58%, respectively, for dogs in the surgery group. Overall median survival time for dogs in the radiotherapy and surgery group (477 months) was significantly longer than time for dogs in the radiotherapy-only group (19.7 months). Results suggest that exenteration of the nasal cavity significantly prolongs survival time in dogs with intranasal neoplasia that have undergone radiotherapy. Exenteration after radiotherapy may increase the risk of chronic complications.

Neuroimaging research in surgically treated pediatric hydrocephalus patients remains challenging due to the artifact caused by programmable shunt. Our previous study has demonstrated significant alterations in the whole brain white matter structural connectivity based on diffusion tensor imaging (DTI) and graph theoretical analysis in children with hydrocephalus prior to surgery or in surgically treated children without programmable shunts. This study seeks to investigate the impact of brain injury on the topological features in the left hemisphere, contratelateral to the shunt placement, which will avoid the influence of shunt artifacts and makes further group comparisons feasible for children with programmable shunt valves. Three groups of children (34 in the control group, 12 in the 3-month post-surgery group, and 24 in the 12-month post-surgery group, age between 1 and 18 years) were included in the study. The structural connectivity data processing and analysis were performed based on DTI and graph theoretical analysis. Specific procedures were revised to include only left brain imaging data in normalization, parcellation, and fiber counting from DTI tractography. Our results showed that, when compared to controls, children with hydrocephalus in both the 3-month and 12-month post-surgery groups had significantly lower normalized clustering coefficient, lower small-worldness, and higher global efficiency (all p  < 0.05, corrected). At a regional level, both patient groups showed significant alteration in one or more regional connectivity measures in a series of brain regions in the left hemisphere (8 and 10 regions in the 3-month post-surgery and the 12-month post-surgery group, respectively, all p  < 0.05, corrected). No significant correlation was found between any of the global or regional measures and the contemporaneous neuropsychological outcomes [the General Adaptive Composite (GAC) from the Adaptive Behavior Assessment System, Second Edition (ABAS-II)]. However, one global network measure (global efficiency) and two regional network measures in the insula (local efficiency and between centrality) tested at 3-month post-surgery were found to correlate with GAC score tested at 12-month post-surgery with statistical significance (all p  < 0.05, corrected). Our data showed that the structural connectivity analysis based on DTI and graph theory was sensitive in detecting both global and regional network abnormality when the analysis was conducted in the left hemisphere only. This approach provides a new avenue enabling the application of advanced neuroimaging analysis methods in quantifying brain damage in children with hydrocephalus surgically treated with programmable shunts.

Wisdom teeth remains impacted in the jaw due to several reasons and surgery of impacted wisdom teeth is one of the most common surgeries in dental clinics. Pain, swelling and trismus are the common complications after this surgery which affect quality of life. In articles, various methods are introduced to control immediate inflammatory-response associated with third-molar surgery. The aim of this study is to evaluate the adjunctive effect of low-level laser Therapy on pain, swelling and trismus after surgical removal of impacted lower third molar. This double-blind randomized controlled trial (RCT) was conducted on two groups of 24 patients (age range of 18-35) that had referred to surgical ward of Faculty of Dentistry, Tabriz University of Medical Sciences for surgery of their mandibular third molar(2015-16). All the subjects were systemically healthy and had at least one impacted mandibular third molar. After surgery, in experimental group, the laser was applied intraorally (inside the tooth socket) and extraorally (at the insertion point of the masseter muscle) immediately after surgery in contact with the target area for 25 seconds each. The laser energy was 2.5 J per area with an energy density of 5 J/ cm 2 at the surface of the probe (spot size= 0.5 cm 2 ). In the other group, as the control group, it was pretended to radiate. Trismus, pain, and swelling were evaluated on the first and seventh days after surgery. The obtained data were evaluated using SPSS 16 software and independent samples T-test. In the group where LLLT had been used, P> 0.05 was calculated for pain, swelling, and trismus on days 1 and 7 after surgery that was not statistically significant. Under limitations of this study, using low-power laser with mentioned parameters, clinically reduces pain, swelling and trismus after surgical removal of impacted mandibular wisdom, but not statistically significant.

Little is known about functional outcomes of ankle arthroplasty compared with arthrodesis. This study compared pre-surgical and post-surgical gait measures in both patient groups. Eighteen patients with end-stage ankle arthritis participated in an ongoing longitudinal study (pre-surgery, 12 months post-surgery) involving gait analysis, assessment of pain and physical function. Outcome measures included temporal-distance, kinematic and kinetic data, the Short Form 36 (SF-36) body pain score, and average daily step count. A mixed effects linear model was used to detect effects of surgical group (arthrodesis and arthroplasty, n = 9 each) with walking speed as a covariate (α = 0.05). Both groups were similar in demographics and anthropometrics. Followup time was the same for each group. There were no complications in either group. Pain decreased (p < 0.001) and gait function improved (gait velocity, p = 0.02; stride length, p = 0.035) in both groups. Neither group increased average daily step count. Joint range of motion (ROM) differences were observed between groups after surgery (increased hip ROM in arthrodesis, p = 0.001; increased ankle ROM in arthroplasty, p = 0.036). Peak plantar flexor moment increased in arthrodesis patients and decreased in arthroplasty patients (p = 0.042). Initial findings of this ongoing clinical study indicate pain reduction and improved gait function 12 months after surgery for both treatments. Arthroplasty appears to regain more natural ankle joint function, with increased ROM. Long-term follow up should may reveal more clinically meaningful differences.

The introduction of endourological procedures such as percutaneous nephrolithotomy and ureterorenoscopy have led to a revolution in the the management of urinary stone disease. The indications for open stone surgery have been narrowed significantly, making it a second- or third-line treatment option. To study the safety and efficacy of retroperitoneal laparoscopic pyelolithotomy in retroperitoneal renal stone. We compared the results of laparoscopic and open surgery in terms of easy accessibility, operative period, renal injuries, and early recovery. This prospective study was conducted on renal pelvic stone cases from January 2009 to February 2016 in Suchkhand Hospital, Agra, India. The study included a total of 1700 cases with the diagnosis of solitary renal pelvic stones. In group A - 850 cases - retroperitoneal laparoscopic pyelolithotomy was performed, while group B - 850 cases - underwent open pyelolithotomy. The mean operative time was less in group B than group A (74.83 min vs. 94.43 min) which was significant (p<0.001). The blood loss was less in the laparoscopic group than in the open group (63 mL vs. 103mL). There were statistically significant differences in the post-operative pain scores, and postoperative complications compared to group B (p<0.001). The mean hospital stay was less in group A (p<0.03), which was significant. Laparoscopic surgery reduces analgesic requirements, hospital stay, and blood loss. The disadvantages include the reduced working space, the cost of equipment and the availability of a trained surgeon.

The aim of this study was to evaluate the precision of bimaxillary surgery performed to correct vertical maxillary excess, when the procedure is sequenced with mandibular surgery first or maxillary surgery first. Thirty-two patients, divided into two groups, were included in this retrospective study. Group 1 comprised patients who received bimaxillary surgery following the classical sequence with repositioning of the maxilla first. Patients in group 2 received bimaxillary surgery, but the mandible was operated on first. The precision of the maxillomandibular repositioning was determined by comparison of the digital prediction and postoperative tracings superimposed on the cranial base. The data were tabulated and analyzed statistically. In this sample, both surgical sequences provided adequate clinical accuracy. The classical sequence, repositioning the maxilla first, resulted in greater accuracy for A-point and the upper incisor edge vertical position. Repositioning the mandible first allowed greater precision in the vertical position of pogonion. In conclusion, although both surgical sequences may be used, repositioning the mandible first will result in greater imprecision in relation to the predictive tracing than repositioning the maxilla first. The classical sequence resulted in greater accuracy in the vertical position of the maxilla, which is key for aesthetics.

This study evaluated the accuracy of mandibular reconstruction and assessed clinical outcomes in both virtual planning and conventional surgery patients. ProPlan CMF surgical planning software was used preoperatively in the virtual planning group. In the virtual planning group, fibula flaps were harvested and osteotomized, and the mandibles were resected and reconstructed assisted by the prefabricated cutting guides and templates. The main outcome measures included the operative time, postoperative computed tomography (CT) scans, facial appearance, and occlusal function. The ischemia time and total operation time were shorter in the virtual planning group than in the conventional surgery group. High precision with the use of the cutting guides and templates was found for both the fibula and mandible, and a good fit was noted among the pre-bent plate, mandible, and fibula segments in the virtual planning group. Postoperative CT scans also showed excellent mandibular contours of the fibula flaps in accordance with virtual plans in the virtual planning group. This study demonstrated that virtual surgical planning was able to achieve more accurate mandibular reconstruction than conventional surgery. The use of prefabricated cutting guides and plates makes fibula flap moulding and placement easier, minimizes the operating time, and improves clinical outcomes.

Timing of surgery in the management of infective endocarditis is controversial, and there is still no definite conclusion on how early the surgery should be performed. This study focuses on the outcomes of surgery during the active period of infective endocarditis in consideration of the duration after diagnosis. One hundred and thirty-four patients with active native valve infective endocarditis who underwent surgery from January 2006 to December 2013 were reviewed retrospectively. They were divided in 2 groups based on timing of surgery: early group (first week after diagnosis, n = 37) and delayed group (2 to 6 weeks after diagnosis, n = 97). Compared to the delayed group, the early group had significantly more patients in New York Heart Association class IV (81% vs. 43.3%), more mechanically ventilated (54.1% vs. 18.6%), more on inotropic support (62.2% vs. 38.1%), and hence a worse EuroSCORE II (14.8% vs. 8.8%). Operative mortality was comparable (5.4% vs. 10.3%) and 7-year survival was similar (77.4% vs. 74.6%). On multivariable regression analysis, delayed surgery did not impact on short- and long-term outcomes. Preoperative cardiac arrest and infection with Haemophilus, Actinobacillus, Cardiobacterium, Eikenella, or Kingella were risk factors for higher operative mortality. Predictors of poor 7-year survival were diabetes mellitus and acute renal failure. Delayed surgery is not associated with worse outcomes. Both early and delayed approaches are safe and provide acceptable results. Timing of surgery should be tailored to each patient's clinical status, not based on duration of endocarditis alone. © The Author(s) 2016.

With a focus on providing high quality care and reducing facility based expenses there has been an evolution in perioperative care by way of enhanced recovery after surgery (ERAS). ERAS allows for a multidisciplinary and multimodal approach to perioperative care which not only expedites recovery but maximizes patient outcomes. This paradigm shift has been generally accepted by most surgical specialties, including plastic surgery. The goal of this study was to evaluate the impact of ERAS on outcomes in cosmetic plastic surgery. A prospective study consisting of phone call questionnaires was designed where patients from two senior plastic surgeons (N.H.R. and J.D.F.) were followed. The treatment group (n = 10) followed an ERAS protocol while the control group (n = 12) followed the traditional recovery after surgery which included narcotic usage. Patients were contacted on postoperative days (POD) 0 through 7+ and surveyed about a number of outcomes measures. The ERAS group demonstrated a significant reduction in postoperative pain on POD 0, 1, 2, and 3 (all P < 0.01). There was also statistically less nausea/vomiting, fatigue/drowsiness, constipation, and hindrance on ambulation compared to the control group (all P < 0.05). Significance was achieved for reduction in fatigue/drowsiness on POD 0 and 1 (P < 0.01), as well as ability to ambulate on POD 0 and 3 (P = 0.044). Lastly, opioid use (P < 0.001) and constipation (P = 0.003) were decreased. ERAS protocols have demonstrated their importance within multiple surgical fields, including cosmetic plastic surgery. The utility lies in the ability to expedite patient's recovery while still providing quality care. This study showed a reduction in postoperative complaints by avoiding narcotics without an increase in complications. Our findings signify the importance of ERAS protocols within cosmetic plastic surgery. 4. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

Previous studies have documented a decrease in proprioceptive capacity in the unstable shoulder. The degree to which surgical approach affects recovery of strength and proprioception is unknown. The recovery of strength and proprioception after open surgery for recurrent anterior glenohumeral instability was compared for 2 surgical procedures. A prospective analysis of 55 consecutive patients with posttraumatic unilateral recurrent anterior glenohumeral instability was performed. Thirty patients (group 1) underwent an open inferior capsular shift with detachment of the subscapularis, and 25 (group 2) underwent an anterior capsulolabral reconstruction. Mean preoperative proprioception and strength values were significantly lower for the affected shoulders in both groups. At 6 months after surgery, there were no significant differences for mean strength and proprioception values between the unaffected and operative sides for group 2 patients. In group 1 patients, however, there were still significant deficits in mean position sense and strength values. Complete restoration of proprioception and strength, however, was evident by 12 months in group 1. This study demonstrates that there are significant deficits in both strength and proprioception in patients with posttraumatic, recurrent anterior glenohumeral instability. Although both are completely restored by 1 year after surgery, a subscapularis-splitting approach allows for complete recovery of strength and position sense as early as 6 months postoperatively. Detachment of the subscapularis delays recovery of strength and position sense for up to 12 months after surgery. Copyright 2010 Journal of Shoulder and Elbow Surgery Board of Trustees.

Purpose Hallux valgus surgery often results in significant postoperative pain. Adequate control of pain is essential for patient satisfaction and improves the outcome of the procedure. This study aimed to investigate the perioperative analgesic effect of a buprenorphine transdermal patch in patients who underwent hallux valgus surgery. Patients and methods A total of 90 patients were randomly divided into the following three groups based on the perioperative analgesic method: flurbiprofen axetil intravenous injection (Group F), oral celecoxib (Group C), and buprenorphine transdermal delivery system (BTDS) (Group BTDS). The pain status, degree of satisfaction, adverse effects, and administration of tramadol hydrochloride for uncontrolled pain were recorded on the night before surgery, postoperative day 1, postoperative day 2, and postoperative day 3. Results The BTDS could effectively control perioperative pain for patients undergoing hallux valgus surgery. The analgesic effect of the BTDS was better than that of oral celecoxib. In addition, statistically significant differences were not observed in the visual analog scale (VAS) scores, adverse effects, and rescue analgesia between the patients who received the BTDS and the patients who received the flurbiprofen axetil intravenous injection. However, the degree of patient satisfaction of the BTDS group was significantly higher (P<0.05) than that of the other two groups. Conclusion The BTDS (a preemptive analgesia regimen) could exert an analgesic effect during the perioperative period for patients who had received hallux valgus surgery, and this effect is beneficial for sustaining postoperative physiological and psychological states and promoting functional rehabilitation.

2014-05-01

For more than a decade, peri-implant tissues have been treated with soft tissue lasers to create a bloodless flap for implant placement and to uncover implants with minimal bleeding, trauma, and anaesthesia. This study was designed to assess if dental implant uncovering is possible with a diode laser without anaesthesia, and to compare its performance with traditional cold scalpel surgery. Thirty patients with a total of 45 completely osseointegrated implants participated in this study. Patients were divided into two groups. For the study group, second-stage implant surgery was done with a 970nm diode laser. For the control group, the implants were exposed with a surgical blade. Certain parameters were used for evaluation of the two techniques. The use of the diode laser obviated the need for local anaesthesia; there was a significant difference between the two groups regarding the need for anaesthesia (P<0.0001). However, there were no significant differences between the two techniques regarding duration of surgery, postoperative pain, time for healing, and success of the implants. The diode laser can be used effectively for second-stage implant surgery, providing both the dentist and the patient with additional advantages over the conventional methods used for implant exposure.

Goal theory states that novices may experience unintended, detrimental learning effects, with decreased performance, when given performance goals on complex tasks. In these situations, it may be more appropriate to give novices learning goals to help avoid these negative consequences. The purpose of this study was to see whether this tenant of goal theory applied to novices learning 2 tasks of fundamentals of laparoscopic surgery (FLS). Medical and physician assistant students were randomized to a performance goals group and a learning goals group. The performance goals consisted of the published proficiency standards of FLS. Both groups were pretested on perception of surgery, self-efficacy, and general affect. Each group underwent a practice session for the peg transfer task. They were tested and scored per the published standards of FLS. The participants completed NASA Task Load Index, task complexity, and postaffect questionnaires related to the peg transfer task. This was repeated with the suture with intracorporeal knot task. Posttest perception of surgery and self-efficacy questionnaires were completed. In total, 48 students participated in the study: 23 in the performance goals group and 25 in the learning goals group. Most of the participants (n = 40) were first-year medical and physician assistant students. There were no significant differences between the groups in perception of surgery, affect, goal commitment, subjective task complexity, subjective workload, and self-efficacy. There were no differences between the groups concerning overall FLS score for both the peg transfer and suturing tasks. Both groups exhibited significant increases in self-efficacy and perception of surgery (p < 0.05). FLS skills can be given to novice learners without concern for detrimental effects as might be expected by other work on goal theory. Given that performance was the same for both groups, surgical educators may have multiple pathways to educational success when incorporating goals into training programs for basic surgical skills.

Third molar surgery is one of the most common surgical procedures performed in general dentistry. Post-operative variables such as pain, swelling and trismus are major concerns after impacted mandibular third molar surgery. Use of passive tube drain is supposed to help reduce these immediate post-operative sequelae. The current study was designed to compare the effect of tube drain on immediate post-operative sequelae following impacted mandibular third molar surgery. To compare the post-operative sequelae after surgical removal of impacted mandibular third molar surgery with or without tube drain. Thirty patients with bilateral impacted mandibular third molars were divided into two groups: Test (with tube drain) and control (without tube drain) group. In the test group, a tube drain was inserted through the releasing incision, and kept in place for three days. The control group was left without a tube drain. The post-operative variables like, pain, swelling, and trismus were calculated after 24 hours, 72 hours, 7 days, and 15 days in both the groups and analyzed statistically using chi-square and t-test analysis. The test group showed lesser swelling as compared to control group, with the swelling variable showing statistically significant difference at post-operative day 3 and 7 (p≤ 0.05) in both groups. There were no statistically significant differences in pain and trismus variables in both the groups. The use of tube drain helps to control swelling following impacted mandibular third molar surgery. However, it does not have much effect on pain or trismus.

It is currently unknown what makes some obese individuals opt for bariatric surgery whereas others choose not to. The aim of this study was to examine whether personality characteristics differed between obese individuals signed up for Roux-en-Y gastric bypass (RYGB) (N=30) and obese individuals not seeking RYGB (N=30) compared to non-obese controls (N=30). All participants completed the NEO Personality Inventory-Revised. The obese RYGB group displayed higher levels of Neuroticism and borderline lower levels of Extraversion compared to the obese non-RYGB and the non-obese group, while the two latter groups did not differ in terms of personality. The Neuroticism domain and possibly the Extraversion domain may therefore be worthwhile to consider in future studies investigating the outcome of bariatric surgery. Copyright © 2014 Elsevier Ltd.

Objective The undergraduate medical curriculum has been overcrowded with core learning outcomes with no formal exposure to plastic surgery. The aim of this study was to compare medical students from two educational settings for the basic understanding, preferred learning method, and factors influencing a career choice in plastic surgery. Design and Setting A prospective cohort study based on a web-based anonymous questionnaire sent to final year medical students at Birmingham University (United Kingdom), McGill University (Canada), and a control group (non-medical staff). The questions were about plastic surgery: (1) source of information and basic understanding; (2) undergraduate curriculum inclusion and preferred learning methods; (3) factors influencing a career choice. A similar questionnaire was sent to non-medical staff (control group). The data was analysed based on categorical outcomes (Chi-square χ2) and level of significance p ≤ 0.05. Results Questionnaire was analysed for 243 students (Birmingham, n = 171/332, 52%) (McGill n = 72/132, 54%). Birmingham students (14%) considered the word “plastic” synonymous with “cosmetic” more than McGill students (4%, p < 0.025). Teaching was the main source of knowledge for McGill students (39%, p < 0.001) while Birmingham students and control group chose the media (70%, p < 0.001). McGill students (67%) more than Birmingham (49%, p < 0.010) considered curriculum inclusion. The preferred learning method was lectures for McGill students (61%, p < 0.01) but an optional module for Birmingham (61%). A similar proportion (18%) from both student groups considered a career in plastic surgery. Conclusions Medical students recognised the need for plastic surgery inclusion in the undergraduate curriculum. There was a difference for plastic surgery source of information, operations, and preferred method of learning for students. The study highlighted the urgent need to reform plastic surgery undergraduate teaching in collaboration with national educational bodies worldwide. PMID:28630768

Purpose Parecoxib provides analgesia following a variety of surgeries, including minor gastrointestinal procedures. To our knowledge, there is no data on parecoxib following major gastrointestinal surgery. This study assessed the efficacy and opioid-sparing effects of parecoxib following major gastrointestinal surgeries. Patients and methods Patients in this analysis were a subset from a large, randomized, double-blind, placebo-controlled trial of parecoxib following noncardiac surgeries and consisted of those undergoing a variety of major gastrointestinal surgeries via laparotomy. Pain, pain interference with function, supplemental opioid utilization, opioid-related symptoms, and Patient/Physician Global Evaluation of Study Medication were compared between placebo and parecoxib groups in the 2−3 days following surgery. Results Significantly (p<0.001) lower pain scores were observed in the parecoxib group (n=111), relative to placebo (n=126), on Day 2 (−33%) and Day 3 (−35%). Pain interference with function scores was also significantly (p<0.001) lower among patients receiving parecoxib compared with placebo on Day 2 (−29%) and Day 3 (−36%). At 24, 48, and 72 hours, the cumulative amount of supplemental morphine consumed was 45%, 41%, and 40% less in patients receiving parecoxib compared with placebo (all p<0.001). The risk of experiencing ≥1 opioid-related symptoms was also significantly lower with parecoxib than with placebo on Day 2 (relative risk=0.75; p<0.001). Specifically, the risks of fatigue and drowsiness were significantly (both p<0.05) lower in patients receiving parecoxib compared to those receiving placebo. Patient and Physician Global Evaluation of Study Medication scores were significantly better in the parecoxib group than in the placebo group (p<0.001). Conclusion This study is the first to demonstrate that multiple-dose parecoxib, initiated upon recovery from anesthesia, provides analgesia and opioid-sparing effects following a variety of major gastrointestinal surgeries employing laparotomy.

Structured Abstract Objective To compare bariatric surgery vs. intensive medical weight management (MWM) in patients with type 2 diabetes (T2DM) who do not meet current NIH criteria for bariatric surgery. To assess whether the soluble form of receptor for advanced glycation endproducts (sRAGE) is a biomarker to identify patients most likely to benefit from surgery. Summary Background Data There are few studies comparing surgery to MWM for patients with T2DM and BMI < 35. Methods 57 patients with T2DM and BMI 30–35 who otherwise met criteria for bariatric surgery were randomized to MWM vs. surgery (bypass, sleeve or band, based on patient preference). The primary outcomes assessed at 6 months were change in insulin resistance (HOMA-IR) and diabetes remission. Secondary outcomes included changes in HbA1c, weight, and sRAGE. Results The surgery group had improved HOMA-IR (−4.6 vs. +1.6; p=0.0004) and higher diabetes remission (65% vs. 0%, p<0.0001) than the MWM group at 6 months. Compared to MWM, the surgery group had lower HbA1c (6.2 vs. 7.8, p=0.002), lower fasting glucose (99.5 vs. 157; p=0.0068) and fewer T2DM medication requirements (20% vs. 88%; p<0.0001) at 6 months. The surgery group lost more weight (7.0 BMI decrease vs. 1.0 BMI decrease, p<0.0001). Higher baseline sRAGE was associated with better weight loss outcomes (r=−0.641; p=0.046). There were no mortalities. Conclusions Surgery was very effective short-term in patients with T2DM and BMI 30–35. Baseline sRAGE may predict patients most likely to benefit from surgery. These findings need to be confirmed with larger studies. ClinicalTrials.gov ID: NCT01423877 PMID:25203878

To evaluate effect of parecoxib sodium pretreatment combined with dexmedetomidine on early postoperative cognitive dysfunction in elderly patients after shoulder arthroscopy. Randomized, double-blind study. University-affiliated teaching hospital. One hundred and fifty-two elderly patients scheduled for shoulder arthroscopy. At 15min before the induction of anesthesia, 152 patients received intravenously parecoxib sodium 40mg and dexmedetomidine at a dose of 0.5μg/kg over 15min, followed by a continuous infusion at a rate of 0.5μg/kg/h until the end of surgery. Then all patients who received postoperative patient-controlled intravenous analgesia were divided 2 groups: sufentanil(0.04μg/kg/h, S group), sufentanil (0.04μg/kg/h) plus dexmedetomidine(0.06μg/kg/h) (SD group). The mini-mental status examination score in SD group was significantly higher than S group at 1, 2 and 7days after surgery. The incidence of postoperative cognitive dysfunction during 7days after surgery in S and SD groups was respectively 17.1% and 6.7%. Compared with the S group, the visual analogue scale scores at rest and upon movement were significantly lower at 6, 14, 24, 36 and 48h after surgery in SD group; analgesia pump liquid amount during 24h after surgery and number of rescue analgesia during 48h after surgery were significantly lower in SD group. Jugular venous oxygen partial pressure and jugular venous oxygen saturation values in SD group were significantly higher than S group at postoperative 24h. The occurrence of nausea and vomiting within 48h after surgery in SD group were significantly lower than S group. We found no complications including respiratory depression and sinus bradycardia within 48h after surgery in all patients. Parecoxib sodium pretreatment combined with dexmedetomidine could reduce the incidence of early postoperative cognitive dysfunction in elderly patients. This might be related to the improvement of postoperative analgesia effect and cerebral oxygen metabolism in patients. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

Different cerebral protection strategies are currently being practiced during noncomplex hemiarch surgery without randomized control studies to show their relative efficacy. We hypothesized that deep hypothermic circulatory arrest (DHCA) alone was adequate for cerebral protection in noncomplex hemiarch surgery. Four hundred sixty-seven patients underwent noncomplex hemiarch surgery between January 2002 and December 2012. Calcified aortas and total arch surgeries were excluded. DHCA alone was used for 276 patients, DHCA with antegrade cerebral perfusion (ACP) was used for 114 patients, and DHCA with retrograde cerebral perfusion (RCP) was used for 77 patients. Preoperative characteristics were similar between groups (12.3% in the DHCA group, 12.3% in the ACP group, and 10.3% in RCP group were reoperations). Patients in the DHCA group had shorter cardiopulmonary bypass times (193 minutes vs 217 minutes; P ≤ .005) and total lower body ischemic times (21 minutes vs 30 minutes; P ≤ .001) than ACP, but not RCP. Rates of reoperations for bleeding, postoperative stroke, and new renal failure did not differ between groups. New onset of cerebrovascular events were seen in 5.4% of patients in the DHCA group versus 6.2% of patients in the ACP group and 6.4% of patients in the RCP group (all P values > .7). Operative mortality in the DHCA group was 4.7% versus 2.6% in the ACP group and 2.6% in the RCP group (all P values > .4). Cox proportional hazard modeling showed no survival differences between groups. Outcomes and survival using DHCA alone were comparable to adjunct cerebral protection methods in patients undergoing noncomplex hemiarch surgery. DHCA alone is as safe as other adjunct complex cerebral protection techniques and simplifies operation without additional risk. Copyright © 2014. Published by Elsevier Inc.

To evaluate the effectiveness of a hydrogel sealant versus a suture in preventing fluid egress after wound leakage in cataract surgery. Twenty-four ophthalmic clinical practices in the United States. Prospective randomized parallel-arm controlled multicenter subject-masked study. Healthy patients having uneventful clear corneal incision (CCI) cataract surgery were eligible for the study. Spontaneous and provoked fluid egress from wounds was evaluated at the time of surgery using a calibrated force gauge. Eyes with leakage were randomized to receive a hydrogel sealant (Resure) or a nylon suture at the main incision site. Incision leakage was reevaluated 1, 3, 7, and 28 days postoperatively. Of 500 eyes, 488 had leakage at the time of cataract surgery. The leak was spontaneous in 244 cases (48.8%), and 488 (97.6%) of all incisions leaked with 1.0 ounce or less of applied force. After randomization, 12 (4.1%) of 295 eyes in the sealant group and 60 (34.1%) of 176 eyes in the suture group had wound leakage with provocation (P<.0001). The overall incidence of adverse ocular events was statistically significantly lower in the sealant group than in the suture group (P<.05). In this study, 97.6% of CCIs leaked after cataract surgery. The hydrogel sealant was safe and effective and better than a suture for the intraoperative management of CCIs with leakage as seen on Seidel testing and for the prevention of postoperative fluid egress.

Obesity increases risk of falling, but the effect of bariatric surgery on fall-related injuries is unknown. The aim of this study was therefore to study the association between bariatric surgery and long-term incidence of fall-related injuries in the prospective, controlled Swedish Obese Subjects study. At inclusion, body mass index was ≥ 34 kg/m 2 in men and ≥38 kg/m 2 in women. The surgery per-protocol group (n = 2007) underwent gastric bypass (n = 266), banding (n = 376), or vertical banded gastroplasty (n = 1365), and controls (n = 2040) received usual care. At the time of analysis (31 December 2013), median follow-up was 19 years (maximal 26 years). Fall-related injuries requiring hospital treatment were captured using data from the Swedish National Patient Register. During follow-up, there were 617 first-time fall-related injuries in the surgery group and 513 in the control group (adjusted hazard ratio 1.21, 95% CI, 1.07-1.36; P = 0.002). The incidence differed between treatment groups (P < 0.001, log-rank test) and was higher after gastric bypass than after usual care, banding and vertical banded gastroplasty (adjusted hazard ratio 0.50-0.52, P < 0.001 for all three comparisons). In conclusion, gastric bypass surgery was associated with increased risk of serious fall-related injury requiring hospital treatment.

Despite extensive research efforts oesophageal cancer remains a malignancy with a poor prognosis. Improvement of treatment is urgently needed. Although multimodality treatment for resectable oesophageal cancer has established it place in standard practice, there are still many differences worldwide in the preferred treatment. The Dutch ChemoRadiotherapy for Oesophageal cancer followed by Surgery Study (CROSS) trial has contributed significantly to the current use of neoadjuvant chemoradiation. This study compared neoadjuvant chemoradiotherapy (CRT) using a moderate radiation dose weekly combined with carboplatin and paclitaxel followed by surgery versus surgery alone. Median overall survival in the CRT group is 49.4 months compared to 24.0 months in the surgery alone group, resulting in an overall survival benefit of 13% in favor of the CRT group (HR, 0.81; 95% CI: 0.70-0.93; P=0.002). Recently the results after long-term follow-up (median 60 months) have been published and confirm the benefit of neoadjuvant CRT to surgery alone. Perioperative mortality rates are low and did not increase by adding CRT (4%) and the CROSS scheme has a favorable toxicity profile. Recurrence patterns in patients treated according to the CROSS protocol report significantly reduced loco regional recurrence in the CRT group (34% to 14%; P<0.001) and less peritoneal carcinomatosis (14% to 4%; P<0.001). With the contemporary focus of research on tumor tailored therapy, the effective and safe CROSS protocol serves as a backbone in many ongoing trials.

Timing of operation for poor-grade aneurysmal subarachnoid hemorrhage: study protocol for a randomized controlled trial

PubMed Central

2013-01-01

Background Subarachnoid hemorrhage is a common and dangerous disease with an unfavorable prognosis. Patients with poor-grade subarachnoid hemorrhage (Hunt & Hess Grades 4–5) are unconscious on admission. Because of the high mortality and disability rate associated with poor-grade subarachnoid hemorrhage, it is often treated conservatively. Timing of surgery for poor-grade aneurysmal subarachnoid hemorrhage is still controversial, therefore this study aims to identify the optimal time to operate on patients admitted in poor clinical condition. Methods/design Ninety-nine patients meeting the inclusion criteria were randomly assigned into three treatment groups. The early surgery group received operation within 3 days after onset of subarachnoid hemorrhage (day of SAH = day 1); the intermediate surgery group received operation from days 4 to 7, and surgery was performed on the late surgery group after day 7. Follow-up was performed 1, 3, and 6 months after aneurysm clipping. Primary indicators of outcome included the Extended Glasgow Outcome Scale and the Modified Rankin Scale, while secondary indicators of outcome were assessed using the Barthel Index and mortality. Discussion This is the first prospective, single-center, observer-blinded, randomized controlled trial to elucidate optimal timing for surgery in poor-grade subarachnoid hemorrhage patients. The results of this study will be used to direct decisions of surgical intervention in poor-grade subarachnoid hemorrhage, thus improving clinical outcomes for patients.

The RiGOR study evaluated the association of treatment and patient-reported outcomes for open-angle glaucoma patients. The Glaucoma Symptom Scale (National Eye Institute-Visual Function Questionnaire (NEI-VFQ) and visual acuity (VA) were collected as quality of life measures. The proportion of patients with improvement of at least two lines of vision was highest in the incisional surgery group (14.2% compared with 9.9% for laser surgery and 10.9% for additional medication). No clinically relevant differences were seen in benefit for the laser surgery or incisional surgery groups compared with additional medications for the Glaucoma Symptom Scale or NEI-VFQ measures or subscales. Differences in quality of life by race need to be explored in further studies.

Respiratory problems occur more frequently in patients who undergo open heart surgery. Intraoperative and postoperative ventilation strategies can prevent these complications and reduce mortality. We hypothesized that PCV would have better effects on gas exchange, lung mechanics and hemodynamics compared to VCV in CABG surgery. Our primary outcome was to compare the PaO 2 /FiO 2 ratio. Patients were randomized into two groups, (VCV, PCV) consisting of 30 individuals each. Two patients were excluded from the study. I/E ratio was adjusted to 1:2 and, RR:10/min fresh air gas flow was set at 3L/min in all patients. In the VCV group TV was set at 8 mL/kg of the predicted body weight. In the PCV group, peak inspiratory pressure was adjusted to the same tidal volume with the VCV group. PaO2/FiO2 was found to be higher with PCV at the end of the surgery. Time to extubation and ICU length of stay was shorter with PCV. Ppeak was similar in both groups. Pplateau was lower and Pmean was higher at the and of the surgery with PCV compared to VCV. The hemodynamic effects of both ventilation modes were found to be similar. PVC may be preferable to VCV in patients who undergo open heart surgery. However, it would be convenient if our findings are supported by similar studies.

Biodegradable implants for internal fixation of ankle fractures may overcome some disadvantages of metallic implants, such as imaging interference and the potential need for additional surgery to remove the implants. The purpose of this study was to evaluate the outcomes after fixation of ankle fractures with biodegradable implants compared with metallic implants. In this prospectively randomized study, 109 subjects with an ankle fracture underwent surgery with metallic (Group I) or biodegradable implants (Group II). Radiographic results were assessed by the criteria of the Klossner classification system and time to bone union. Clinical results were assessed with use of the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scale, Short Musculoskeletal Function Assessment (SMFA) dysfunction index, and the SMFA bother index at three, six, and twelve months after surgery. One hundred and two subjects completed the study. At a mean of 19.7 months, there were no differences in reduction quality between the groups. The mean operative time was 30.2 minutes in Group I and 56.4 minutes in Group II (p < 0.001). The mean time to bone union was 15.8 weeks in Group I and 17.6 weeks in Group II (p = 0.002). The mean AOFAS score was 87.5 points in Group I and 84.3 points in Group II at twelve months after surgery (p = 0.004). The mean SMFA dysfunction index was 8.7 points in Group I and 10.5 points in Group II at twelve months after surgery (p = 0.060). The mean SMFA bother index averaged 3.3 points in Group I and 4.6 points in Group II at twelve months after surgery (p = 0.052). No difference existed between the groups with regard to clinical outcomes for the subjects with an isolated lateral malleolar fracture. The outcomes after fixation of bimalleolar ankle fractures with biodegradable implants were inferior to those after fixation with metallic implants in terms of the score on the AOFAS scale and time to bone union. However, the difference in the final AOFAS score between the groups may not be clinically important. The outcomes associated with the use of biodegradable implants for the fixation of isolated lateral malleolar fractures were comparable with those for metallic implants.

Background: Localized macular edema and retinal nerve fiber layer (RNFL) thinning have been reported shortly after laser in situ keratomileusis (LASIK) in adults. However, it is still unclear how LASIK affects the retina of children. This study aimed to investigate the macular retina and RNFL thickness in children with refractive amblyopia who underwent femtosecond laser-assisted LASIK (FS-LASIK). Methods: In this study, we included 56 eyes of 32 patients with refractive amblyopia who underwent FS-LASIK in our hospital from January 2012 to December 2016. Foveal (foveal center retinal, parafoveal retinal, and perifoveal), macular inner retinal (superior and inferior), and peripapillary RNFL thicknesses (superior, inferior, temporal, and nasal) were measured using Fourier-domain optical coherence tomography before surgery and 1 day, 3 days, and 1 week after surgery. We divided these patients into three groups based on their refractive error: High myopic group with 22 eyes (equivalent sphere, >6.00 D), mild myopic group with 19 eyes (equivalent sphere, 0–6.00 D), and hyperopic group with 15 eyes (equivalent sphere, >+0.50 D). We compared the macular retina and RNFL thickness before and after LASIK. A paired simple t-test was used for data analysis. Results: One week after surgery, the visual acuity for all 56 eyes of the 32 patients reached their preoperative best-corrected vision. Visual acuity improved two lines or better for 31% of the patients. The residual refractive errors in 89% of the patients were within ±0.5 D. In the high myopic group, the foveal center retinal and parafoveal retinal thicknesses were thicker 1 day and 3 days after surgery than before surgery (t = 2.689, P = 0.012; t = 2.383, P = 0.018, respectively); no significant difference was found 1 week after surgery (P > 0.05). The foveal center retinal and parafoveal retinal thicknesses were greater 1 day after surgery than they were before surgery (P = 0.000 and P = 0.005, respectively) in the mild myopic and hyperopic groups. No significant difference was found 3 days or 1 week after surgery (P > 0.05). In all three groups, no significant difference was found in the macular inner retinal or peripapillary RNFL thickness 1 day, 3 days, or 1 week after surgery (P > 0.05). Conclusions: The foveal center retinal edema after FS-LASIK is mild and reversible in children, that mostly occurred in the high myopic group with no effect on the visual acuity, and is always relieved within 1 week.

The epsilon aminocaproic acid is an antifibrinolytic used in cardiovascular surgery to inhibit the fibrinolysis and to reduce the bleeding after CPB. [corrected] To analyze the influence of the using of epsilon aminocaproic acid in the bleeding and in red-cell transfusion requirement in the first twenty-four hours postoperative of mitral valve surgery. Prospective studying, forty-two patients, randomized and divided in two equal groups: group #1 control and group #2--epsilon aminocaproic acid. In Group II were infused five grams of EACA in the induction of anesthesia, after full heparinization, CPB perfusate after reversal of heparin and one hour after the surgery, totaling 25 grams. In group I, saline solution was infused only in those moments. Group #1 showed average bleeding volume of 633.57 ± 305,7 ml, and Group #2, an average of 308.81 ± 210.1 ml, with significant statistic difference (P = 0.0003). Average volume of red-cell transfusion requirement in Groups 1 and 2 was, respectively, 942.86 ± 345.79 ml and 214.29 ± 330.58 ml, with significant difference (P < 0.0001). The epsilon aminocaproic acid was able to reduce the bleeding volume and the red-cell transfusion requirement in the immediate postoperative of patients submitted to mitral valve surgery.

A questionnaire survey of the perception of plastic surgery amongst 1567 members of the public, general practitioners and medical students is presented. Closed-ended format questions were designed to assess understanding of the range of conditions managed by plastic surgeons. Respondents were asked to match nine surgical specialists with 40 conditions or procedures. To investigate understanding of the multidisciplinary nature of some surgery, respondents were asked which type of surgeon might have a supplementary role. Completed questionnaires from 1004 members of the public, 335 general practitioners, and 228 medical students are presented (responses rate>65%). Significant differences were identified between public respondents and other groups. Plastic surgery was associated with reconstruction for trauma and cancer and procedures with a strong aesthetic element by all three groups. The public were poorly informed about some core plastic surgery including burns, melanoma and hand surgery. General practitioner and student respondents had a better understanding of the diversity of the specialty. However, both groups considered orthopaedic surgeons and not plastic surgeons to be hand surgeons. The strengths and weaknesses of this study are discussed together with potential areas for education and promotion.

Damage control surgery (DCS) is an important option in the store of war surgery and surgery of trauma. The main purpose of our investigation was to specify the percentage of the injured who need DCS. We performed retrospective study of the patients in the combat operations in Chechnya (1994-2002) and in peacetime (2005-2010). Total lethality in group with the standard surgical approach was 62.3%. It was significantly higher than the lethality in group of patients who underwent DCS - 50.0% (p < 0.05). Thus, the experience of DCS in War Surgery Department confirms that DCS is perspective tendency in treatment of patients with severe and extremely severe trauma, and allows decreasing lethality in 12.3%.

With proton pump inhibitors and current sophisticated endoscopic techniques, the number of patients requiring surgical intervention for upper gastrointestinal bleeding has decreased considerably while trans-arterial embolization is being used more often. There are few direct comparisons between the effectiveness of surgery and embolization. A retrospective study of patients from two Australian teaching hospitals who had surgery or trans-arterial embolization (n = 103) for severe upper gastrointestinal haemorrhage between 2004 and 2012 was carried out. Patient demographics, co-morbidities, disease pathology, length of stay, complications, and overall clinical outcome and mortality were compared. There were 65 men and 38 women. The median age was 70 (range 36-95) years. Patients requiring emergency surgical intervention (n = 79) or trans-arterial embolization (n = 24) were compared. The rate of re-bleeding after embolization (42%) was significantly higher compared with the surgery group (19%) (P = 0.02). The requirement for further intervention (either surgery or embolization) was also higher in the embolization group (33%) compared with the surgery group (13%) (P = 0.03). There was no statistical difference in mortality between the embolization group (5/24, 20.8%) and the surgical group (13/79, 16.5%) (P = 0.75). Emergency surgery and embolization are required in 2.6% of patients with upper gastrointestinal bleeding. Both techniques have high mortalities reflecting the age, co-morbidities and severity of bleeding in this patient group. © 2014 Royal Australasian College of Surgeons.

Calculus pyonephrosis is difficult to manage. The aim of this study is to explore the value of a patented suctioning sheath assisted minimally invasive percutaneous nephrolithotomy (MPCNL) in the treatment of calculus pyonephrosis. One hundred and eighty two patients with calculus pyonephrosis were randomizely divided into observation group (n = 91) and control group (n = 91). The control group was treated with MPCNL traditionally using peel-away sheath while the observation group was treated with MPCNL using the patented suctioning sheath. All the patients in the observation group underwent one stage surgical treatment, 14 patients in the control group underwent first-stage surgery with the rest of the group underwent one stage surgery. The complication rate was 12.1% in the observation group, significantly lower than the rate in the control group which was 51.6%; One surgery stone clearance in the observation group was 96.7% while it was 73.6% in the control group; operative time in the observation group was (54.5 ± 14.5) min, compared to (70.2 ± 11.7) min in the control group; the bleeding amount in the observation group was (126.4 ± 47.2) ml, compared to (321.6 ± 82.5) ml in the control group; the hospitalization duration for the observation group was (6.4 ± 2.3) days, compared to (10.6 ± 3.7) days in the control group. Comparison of the above indicators, the observation group was better than the control group with significant difference (p < 0.001 each). Minimally invasive percutaneous nephrolithotomy with the aid of the patented suctioning sheath in the treatment of calculus pyonephrosis in one surgery is economic, practical, and warrants clinical promotion.

To compare the health-related quality of life in patients with narrow gastric tube and whole stomach reconstructions after oncologic esophagectomy. In a prospective randomized single-center study from 2007 to 2008, 104 patients underwent esophagectomy for cancer. To assess health-related quality of life, the questionnaire (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 and the Oesophagus-Specific Quality of Life Questionnaire 18) was administered at 3 weeks, 6 months, 1 year, and 2 years after surgery. The perioperative complication rate was 26.9% in narrow gastric tube group and 48.1% in whole stomach group (P = 0.31). At the time of 3 weeks after surgery, the reflux and dyspnea scores were higher in whole stomach group than in narrow gastric tube group, which meant that the patients in whole stomach group suffered more severe problem. At the time of 6 months and 1 year after surgery, the reflux scores were lower in narrow gastric tube group than in whole stomach group, which revealed that there were less problems of reflux in the patients of narrow gastric tube group; meanwhile, the score of physical function scale in narrow gastric tube group was higher conversely, which suggested that the patients gain a better status in physical function. Nausea and vomiting is the only notable symptom that was worse in whole stomach group at the time of 2 years after surgery, which suggested that patients in whole stomach group suffered more severe nausea and vomiting. Narrow gastric tube reconstruction may be a good alternative choice for patients undergoing oncologic esophagectomy in view of better health-related quality of life after the surgery.

The growing need for surgeons who are educated and trained in bariatric surgery has raised many issues related to training in this field. This study was performed to evaluate the safety and efficacy of laparoscopic sleeve gastrectomy (SG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) performed by doctors-in-training during their residency in general surgery. Tertiary referral university teaching hospital, Poland. We retrospectively analyzed the data of patients who underwent bariatric surgery. One group underwent surgery performed by at least third-year residents learning particular types of surgeries (trainee group), and the second group underwent surgeries performed by experienced bariatric surgeons (mentor group). The primary endpoint was the safety of the procedures. We analyzed factors related to the intraoperative and postoperative course. The secondary endpoint was long-term weight reduction. A lower body mass index (BMI), fewer co-morbidities, and preferably female sex were the selection criteria for patients in the trainee group. We enrolled 408 patients who met all inclusion criteria. Among them, 233 underwent SG and 175 underwent LRYGB. For both SG and LRYGB, the median maximum preoperative weight was significantly lower in the trainee than mentor group. We found no statistically significant differences in the demographic factors or co-morbidities between the 2 groups. The median duration of SG and LRYGB surgery was significantly longer in the trainee than mentor group. The median number of stapler firings during SG was significantly lower in the trainee than mentor group. The number of stapler firings during LRYGB did not differ between the 2 groups. The incidence of intraoperative difficulties, which were based on the operator's subjective opinion, was higher in the trainee than mentor group for both SG and LRYGB. However, intraoperative difficulties had no significant impact on the intraoperative complication rate or risk of perioperative complications. The average percentage weight loss (%WL), percentage excess weight loss (%EWL), and percentage excess BMI loss (%EBMIL) in the all study group were 31.14%±9.11%, 56.17%±17.27%, and 65.42%±19.28%, respectively. For patients who underwent SG, we found no significant difference in %WL, %EWL, or %EBMIL between the trainee and mentor groups. The performance of bariatric surgeries by residents does not affect the risk of reoperation, intraoperative adverse events, or surgical complications. Performance of SG and LRYGB by trainees takes significantly longer but has no untoward consequences for the patient. Both SG and LRYGB performed by a doctor-in-training and experienced operator lead to comparable outcomes in terms of weight reduction. Copyright © 2016 American Society for Bariatric Surgery.

This study describes the bone formation stimulated by the application of a type of chalcone to critical-size defects in rat calvarial bone. Sixty female Wistar rats were divided into 6 groups of 10 animals per group: control (no treatment), vehicle (vaseline) and the chalcone (1-phenyl-3-(4-chlorophenyl)-2-propen-1-one) suspended in vaseline at 10%. A critical-size defect of 5 mm was prepared using a trephine in the calvarial bone, after which the treatment was applied, in a single dose, according to the experimental group. The samples were evaluated macroscopically using ImageJ software, and histologically 30 and 45 days after surgery. At 30 days after surgery, there was significant bone formation (p < 0.05) in the groups treated with chalcone, compared with the other groups. Many active osteoblasts were observed adjacent to the borders of the newly formed bone tissue. 45 days after surgery in the chalcone group, the surgical defects showed complete bone closure. The results of this study suggest that chalcone has significant potential to induce the formation of new bone. Copyright © 2013 European Association for Cranio-Maxillo-Facial Surgery.

The objective of the study is to perform a systematic review to compare the clinical outcomes and complications of anterior surgery with posterior surgery for multilevel cervical myelopathy (MCM). MEDLINE, EMBASE databases and other databases were searched for all the relevant original articles published from January 1991 to November 2009 comparing anterior with posterior surgery for MCM. Subgroup analysis was performed according to the follow-up years. The following end points were mainly evaluated: final follow-up JOA (Japanese Orthopaedic Association) scale, recovery rate and complication outcomes. Ten articles fulfilled all inclusion criteria. For multilevel CSM patients, the final follow-up JOA score for the anterior group was significantly higher than the posterior group (p < 0.05, WMD 0.83 [0.24, 1.43]) in the ‘follow-up time ≤5 years’ subgroup, but had no significant differences in the ‘follow-up time >5 years’ subgroup (p > 0.05). The recovery rate for the anterior group was significantly higher than the posterior group (p < 0.05, WMD 10.08 [1.39, 18.78]) in the ‘follow-up time ≤5 years’ subgroup. No study reported the recovery rate for the follow-up time >5 years. For multilevel OPLL patients, the final follow-up JOA score and recovery rate for the anterior group were both significantly higher than the posterior group in the ‘follow-up time ≤5 years’ subgroup (p < 0.05, WMD 2.50 [0.16, 4.85]; p < 0.05, WMD 29.48 [29.09, 29.87], respectively). One study [31] which mean follow-up time was 6 years was enrolled in the ‘follow-up time >5 years’ subgroup. The results showed there was no significant difference in final follow-up JOA score and recovery rate between anterior and posterior group for patients with occupying ratio of OPLL <60% (p > 0.05), while in patients with occupying ratio ≥60%, the final follow-up JOA score and recovery rate of anterior surgery were both superior to that of posterior surgery (p < 0.05). For both multilevel CSM and OPLL patients, the complications for the anterior group were significantly more than the posterior group in the ‘follow-up time ≤5 years’ subgroup (p < 0.05, OR 7.33 [2.96, 18.20] for CSM patients; p < 0.05, OR 4.44 [1.80, 10.98] for OPLL patients), but were similar to the posterior group in the ‘follow-up time >5 years’ subgroup (p > 0.05). In conclusion, anterior surgery had better clinical outcomes and more complications at the early stage after operation for both multilevel CSM and OPLL patients. At the late stage, posterior surgery had similar clinical outcomes and complications to anterior surgery for CSM patients, and OPLL patients with occupying ratio of OPLL <60%. While for OPLL patients with occupying ratio ≥60%, anterior surgery had superior clinical outcome to posterior surgery. PMID:20582710

Transdermal buprenorphine, which is used in chronic pain management, has rarely been studied for use in acute pain management. The aim of this study was to compare the safety and efficacy of transdermal buprenorphine patch to oral tramadol for post-operative analgesia, following proximal femur surgeries. Fifty adult patients undergoing surgery for hip fracture under spinal anaesthesia were included in this study. One group (Group TDB) received transdermal buprenorphine 10 mcg/h patch applied a day before the surgery and other group received oral tramadol 50 mg three times a day for analgesia (Group OT). They were allowed to take diclofenac and paracetamol tablets for rescue analgesia. Pain scores at rest, on movement, rescue analgesic requirement and side effects were compared between the groups over 7 days. Chi-square and independent sample t -test were used for categorical and continuous variables, respectively. Resting pain scores and pain on movement were significantly lower in TDB Group on all 7 days starting from 24 h post-operatively. Rescue analgesic requirement was significantly lower in TDB Group compared to OT Group. All the patients needed rescue analgesic in OT Group whereas 68% of the patients needed the same in TDB Group. Incidence of vomiting was less and satisfaction scores were much higher in TDB Group as compared to OT Group (79% vs. 66%, P < 0.001). Transdermal buprenorphine can be safely used for post-operative analgesia and is more efficacious in reducing post-operative pain after 24 hours, with fewer side effects when compared to oral tramadol.

Summary Background Idiopathic granulomatous mastitis (IGM) is an uncommon chronic inflammatory disease of the breast with uncertain optimal treatment regimen. In this study, our purpose was to report our clinical experience with 74 IGM patients who were treated wide local excision with or without steroid therapy. Patients and Method 74 cases diagnosed histologically as IGM were identified from surgical and pathological records between January 1995 and January 2012. Group 1 (surgery-only group) comprised 53 patients, and the 21 patients in group 2 were treated with corticosteroids prior to surgical treatment (steroid-and-surgery group). Results Follow-up data were complete for 67 (91.7%) of the 73 patients. Recurrence developed in 4 (7.5%) patients in the surgery-only group, while there was no recurrence in the steroid-and-surgery group; the difference was not statistically significant (p = 0.19). Conclusion Systemic steroid therapy with surgical resection is the recommended first-line treatment strategy for IGM. PMID:24944554

Recently, the use of hamstring tendons in anterior cruciate ligament repair has been increasing. However, tendon-to-bone healing occurs slowly, which can be a problem to an early return to sport activities. The use of growth factors from platelets seems to improve tissue healing. We enrolled 40 patients in a prospective study that were submitted to an anatomic reconstruction of the anterior cruciate ligament. Patients were sequentially enrolled into four groups: group A without platelet-rich plasma (PRP); group B with PRP in femoral tunnels at the end of surgery; group C with PRP in femoral tunnels at the end of surgery and intra-articular at 2- and 4 weeks after surgery; group D with PRP activated with thrombin in the femoral tunnels. All patients underwent magnetic resonance imaging of the knee 3 months after surgery to evaluate the signal intensity of the fibrous interzone (FIZ) in the femoral tunnels. We did not find any difference among the groups when comparing the signal intensity of the FIZ on magnetic resonance imaging.

To determine hospitalization durations and mortalities of elderly in the Cardiovascular Surgery Intensive Care Unit. The retrospective study was conducted in a Cardiovascular Surgery Intensive Care Unit in Turkey and comprised patient records from January 1 to December 31, 2011. Computerized epicrisis reports of 255, who had undergone a cardiac surgery were collected. The patients were grouped according to their ages, Group I aged 65-74 and Group II aged 75 and older. European society for Cardiac Operative Risk Evaluation scores of the two groups were compared using SPSS 17. Overall, there were 80 (31.37%) females and 175 (68.62%) males. There were 138 (54.1%) patients in Group I and 117 (45.9%) in Group II. Regarding their hospitalization reasons, it was determined that 70 (27.5%) patients in Group I and 79 (30.9%) patients in Group II were treated with the diagnosis ofcoronary artery disease. The average hospitalization duration of patients in the intensive care unit was determined to be 11.57 +/- 0.40 days. Regarding the EuroSCORE score intervals of patients, 132 (51.8%) had 3-5 and 225 (88.2%) patients were transferred to the Cardiovascular Surgery and then all of them were discharged; 5 (4.1%) had a mortal course; and 11 (7.7%) were transferred to the anaesthesia intensive care unit. The general mortality rates are very low in the Cardiovascular Surgery Intensive Care Unit and the patients have a good prognosis.

Robotic surgery has witnessed a huge expansion. Robotic simulators have proved to be of major interest in training. Some authors have suggested that prior experience in micro-surgery could improve robotic surgery training. To test micro-surgery as a new approach in training, we proposed a prospective study comparing the surgical performance of micro-surgeons with that of general surgeons on a robotic simulator. 49 surgeons were enrolled; 11 in the micro-surgery group (MSG); 38 n the control group (CG). Performance was evaluated based on five dV-Trainer® exercises. MSG achieved better results for all exercises including exercises requiring visual evaluation of force feed-back, economy of motion, instrument force and position. These results show that experience in micro-surgery could significantly improve surgeons' abilities and their performance in robotic training. So, as micro-surgery practice is relatively cheap, it could be easily included in basic robotic surgery training. Copyright © 2013 John Wiley & Sons, Ltd.

There is a shortage of orthopaedic surgeons in Malawi. Orthopaedic clinical officers (OCOs) treat trauma patients and occasionally perform major orthopaedic surgery. No studies have assessed the efficacy and safety of their work. The aim of this study was to evaluate their contribution to major orthopaedic surgery at Zomba Central Hospital. Data about orthopaedic procedures during 2006-2010 were collected from theatre books. We selected major amputations and open reductions and plating for outcome analysis and collected details from files. We compared patients operated by OCOs alone ('OCOs alone' group) and by surgeons or OCOs assisted by surgeons ('Surgeon present' group). OCOs performed 463/1010 major (45.8%) and 1600/1765 minor operations (90.7%) alone. There was no difference in perioperative outcome between both groups. OCOs carry out a large proportion of orthopaedic procedures with good clinical results. Shifting of clinical tasks including major orthopaedic surgery can be safe. Further prospective studies are recommended.

Laparoscopic surgical procedures require a high level of cognitive and psychomotoric skills. Thus, effective training methods to acquire an adequate level of expertise are crucial. The aim of this study was to investigate the effect of preoperative warm up training on surgeon׳s performance during gynecologic laparoscopic surgery. In this randomized controlled trial, surgeons performed a preoperative warm up training using a virtual reality simulator before laparoscopic unilateral salpingo-oophorectomy. Serving as their own controls, each subject performed 2 pairs of laparoscopic cases, each pair consisting of 1 case with and 1 without warm up before surgery. Surgeries were videotaped and psychomotoric skills were rated using objective structured assessment of technical skills (OSATS) and the generic error rating tool by a masked observer. Perioperative complications were assessed. Statistical analysis was performed using a mixed model, and mean OSATS scores were compared between both the groups. In total, data of 10 surgeons and 17 surgeries were available for analysis. No differences between educational level and surgical experiences were observed between the groups. Mean standard error psychomotoric and task-specific OSATS scores of 19.8 (1.7) and 3.7 (0.2) were observed in the warm up group compared with 18.6 (1.7) and 3.8 (0.2) in the no warm up group, respectively (p = 0.51 and p = 0.29). Using generic error rating tool, the total number of errors was 8.75 (2.15) in the warm up group compared with 10.8 (2.18) in the no warm-up group (p = 0.53). Perioperative complications and operating time did not differ between both the groups. The present study suggests that warm-up before laparoscopic salpingo-oophorectomy does not increase psychomotoric skills during surgery. Moreover, it does not influence operating time and complication rates. (Medical University of Vienna-IRB approval number, 1072/2011, ClinicalTrials.gov number, NCT01712607).

To determine if endolymphatic shunt surgery concurrent with vestibular nerve section improves hearing outcome compared with vestibular nerve section alone. Retrospective observational study with cross-sectional survey. Tertiary otologic private practice. Thirty-five patients who underwent vestibular nerve section and endolymphatic shunt surgery and 17 patients who had vestibular nerve section alone between 1985 and 2000. Chart review and correspondence for audiogram results and survey. Hearing at last follow-up. Hearing Handicap Inventory, Dizziness Handicap Inventory, Tinnitus Handicap Inventory, and SF-36. Eight patients in the vestibular nerve section and 15 in the vestibular nerve section and endolymphatic shunt surgery group had an audiogram at more than 16 months after surgery available for review. In the vestibular nerve section group, three patients had same hearing whereas five were worse. In the vestibular nerve section and endolymphatic shunt surgery group, 2 patients showed improvement, 2 were the same, and 11 were worse. There was no significant difference in the change from preoperative pure tone average or Word Discrimination Score to postoperative levels between the surgical groups. Eighteen patients had serviceable hearing preoperatively. Five of 8 in the vestibular nerve section and 4 of 10 in the vestibular nerve section and endolymphatic shunt surgery groups maintained serviceable hearing postoperatively. Of the 52 patients, 33 responded to the survey (63%). There were no significant differences between the groups for Dizziness Handicap Inventory, Hearing Handicap Inventory, Tinnitus Handicap Inventory, or SF-36, suggesting that patient-oriented outcomes are the same in both groups. Concurrent endolymphatic shunt surgery and vestibular nerve section does not improve hearing or tinnitus outcome over vestibular nerve section alone.

The purpose of the present study was to evaluate the efficacy of midazolam-ondansetron combination in prevention of postoperative nausea and vomiting (PONV) after middle ear surgery and its comparison with using midazolam or ondansetron alone. One hundred and forty patients were enrolled in four groups to receive midazolam 0.75 mg/kg in group M, ondansetron 4 mg in group O, midazolam 0.75 mg/kg and ondansetron 4 mg in group MO, and saline 0.90% in group S intravenously just before anesthesia. Assessment of nausea, vomiting, rescue antiemetic, and side effects of study drugs such as headache and dizziness was carried out postoperatively for 24 h. The incidence of PONV was significantly smaller in group MO than group M and group O, while there was no significant difference between group M and group O during the first 24 h postoperatively. Requirement to the additional antiemetic was significantly more in group S (71.4%) compared to other groups, while in group MO (11.4%) was lower than group M (31.4%) and group O (34.3%). Our study showed that prophylactic administration of midazolam 0.75 mg/kg combined with ondansetron 4 mg was more effective than using midazolam or ondansetron alone in prevention of PONV after middle ear surgery.

This randomized, double-blinded, prospective study was performed to compare the intraoperative hemodynamic variables and the patient-reported outcomes, such as intra- and postoperative analgesia and patient satisfaction, of retrobulbar block, sub-Tenon block, and topical anesthesia during cataract surgery under monitored anesthesia care. Eighty-one patients, ASA physical status I-III, undergoing elective cataract surgery under monitored anesthesia care, aged between 43 and 78 years, were randomly assigned to three groups: retrobulbar block (group R), sub-Tenon block (group S), or topical anesthesia (group T). Three minutes after the start of monitored anesthesia care with lidocaine-propofol-remifentanil mixture, an ophthalmologist performed regional anesthesia. Intraoperative hemodynamics, pain score, and patients' satisfaction with the anesthetic experiences were recorded by a study-blinded anesthesiologist. Mean arterial pressure and heart rate in group R were significantly higher than those in groups S and T during and just after the regional block (p<0.05). Group R required smaller dosage of patient controlled sedation and fewer supplemental bolus doses than groups S and T (p<0.05). On the other hand, group S showed the highest satisfaction scores among the three groups (p<0.05). Sub-Tenon block seems to be better than retrobulbar block and topical anesthesia in patient satisfaction though adequate analgesia was achieved after retrobulbar block during cataract surgery under monitored anesthesia care.

The research subjects were drawn from patients with primary early resectable breast cancer treated in the breast disease centers of six three-level hospitals in Beijing from 1 January 2010 to 31 December 2012. The participants were allocated to a breast-conserving surgery group (breast-conserving group) or a total mastectomy group (total mastectomy group). Enhanced MRI was used to measure breast volume, longest diameter of tumor and tumor volume. The correlations between these measurements and those derived from histopathologic findings were assessed. The relationships between the success rate of breast-conserving surgery and MRI- and pathology-based measurement results were statistically analyzed in the breast-conserving group. The study included 461 cases in the total mastectomy group and 195 in the breast-conserving group. Allocation to these groups was based on clinical indications and patient preferences. The cut-off for concurrence between MRI- and pathology-based measurements of the longest diameter of tumor was set at 0.3 cm. In the total mastectomy group, the confidence interval for 95% concurrence of these measurements was 35.41%-44.63%. Correlation coefficients for MRI and histopathology-based measurements of breast volume, tumor volume and tumor volume/breast volume ratio were r = 0.861, 0.569, and 0.600, respectively (all P < 0.001). In the breast-conserving group, with 0.30 cm taken as the cut-off for concurrence, the 95% confidence interval for MRI and pathology-based measurements of the longest diameter of tumor was 29.98%-44.01%. The subjective and objective success rates for breast-conserving surgery were 100% and 88.54%, respectively. There were significant correlations between dynamic enhanced MRI- and histopathology-based measurements of the longest diameter of breast lesions, breast and tumor volumes, and breast volume/tumor volume ratios. Preoperative MRI examination improves the success rate of breast-conserving surgery.

This study compared the effectiveness of prophylactic administration of topical flurbiprofen 0.03% and nepafenac 0.1% in maintaining mydriasis during small incision cataract surgery (SICS). This study was a prospective, randomized, double-blind comparative study in adult cataract patients given topical flurbiprofen or nepafenac prior to SICS and capsular bag intraocular lens (IOL) implantation at a tertiary care hospital. Horizontal and vertical diameters of pupil were measured at the beginning and end of surgery, and the mean values were compared across the two groups. Unpaired t-test and Fisher's exact test were used to analyse the results. A total of 70 eyes of cataract surgery patients, 33 males and 37 females, with a mean age of 58.5 ± 11.24 years, were included in the study. The mean horizontal and vertical diameters of the two groups were similar at the start of surgery. Significant differences were seen after IOL implantation, with the nepafenac group having the larger mean diameters in both horizontal (P = 0.03) and vertical (P = 0.04) pupillary measurements. Topical nepafenac has been shown to be a more effective inhibitor of meiosis during SICS and provides a more stable mydriatic effect compared to topical flurbiprofen.

To evaluate postoperative pain intensity and length of hospital stay after open or robotic thoracic surgery in a standardized postoperative pain therapy setting. In the present retrospective (oberservation period: January 2015 until January 2016) study we matched data of 38 patients with robotic thoracic surgery ("robotic patients"; age: 62.2 years, male gender: 42.1%) with 38 patients with open thoracic surgery ("open patients"; age: 62.5 years, male gender: 42.1%). Power analysis indicated that 36 patients per group would be required. 68% of all patients received an epidural catheter, and 32% a systemic opioid based analgesia. Postoperative pain intensity in "robotic patients" was lower at rest on postoperative day 3-5 compared to "open patients" (NRS POD 3 robotic surgery 0.5±1.0 vs. open surgery 1.0±1.6, p = 0.04; NRS POD 4 robotic surgery 0,5 ± 1.0 vs. open surgery 1.1±1.3, p=0.04; NRS POD 5 robotic surgery 0.7 ± 1.0 vs. open surgery 1.5±1.5, p=0.003). Chest tube duration was shorter in "robotic patients" (2.9 ± 2.0 days vs. 4.9 ± 2.2 days; p < 0.001). Moreover, length of hospital stay was shorter in "robotic patients" than in "open patients" (6.9 days vs. 8.0 days; p = 0.02). There was no significant difference in postoperative opioid consumption between the groups. Nearly 95% of patients were discharged home with an oral opioid in both groups. Patients after robotic pulmonary resection experience lower postoperative pain and are discharged earlier from hospital than patients after open thoracic surgery. The study design is retrospectively.

Oxygen, routinely administered during surgery to avoid hypoxia, poses risks including increased likelihood of surgical room fires and predisposition to retinal phototoxicity in patients. Compressed air to supplement ventilation may be safer than oxygen. The purpose of this study was to determine whether hypoxia occurs more frequently when compressed air replaces supplemental oxygen during ophthalmic surgery. A convenience sample of 111 patients was randomly assigned to receive supplemental oxygen (group 1) or compressed air (group 2). Patients with serious cardiac or pulmonary disease were excluded. Blood oxygen levels were monitored during surgery by pulse oximetry. Oxygen was administered to all group 2 patients whose oxygen saturation fell to less than 90% or by more than 5% below baseline. No differences were observed between groups in age, ASA classification, type of surgery, or anesthetic drugs or doses. Minor, but statistically higher oxygen values were observed in group 1. The frequency with which oxygen saturation decreased below 90% or below 5% of baseline was similar in both groups. Supplemental oxygen is not required routinely in selected patients undergoing ophthalmic surgery. By using compressed air, the risk of operating room fires and retinal phototoxicity may be reduced.

Background. This prospective, controlled, parallel-group observational study investigated the efficacy of a spray containing hyaluronic acid and dexpanthenol to optimise regular treatment after nasal cavity surgery in 49 patients with chronic rhinosinusitis. Methods. The control group received standard therapy. Mucosal regeneration was determined using rhinoscopy sum score (RSS). Pre- and postoperative nasal patency was tested using anterior rhinomanometry. The participants were questioned about their symptoms. Results. Regarding all RSS parameters (dryness, dried nasal mucus, fibrin deposition, and obstruction), mucosal regeneration achieved good final results in both groups, tending to a better improvement through the spray application, without statistically significant differences during the whole assessment period, the mean values being 7.04, 5.00, 3.66, and 3.00 (intervention group) and 7.09, 5.14, 4.36, and 3.33 (control group). No statistically significant benefit was identified for nasal breathing, foreign body sensation, and average rhinomanometric volume flow, which improved by 12.31% (control group) and 11.24% (nasal spray group). Conclusion. The investigational product may have additional benefit on postoperative mucosal regeneration compared to standard cleaning procedures alone. However, no statistically significant advantage could be observed in this observational study. Double-blind, controlled studies with larger populations will be necessary to evaluate the efficacy of this treatment modality.

This study was designed to evaluate the effectiveness of lavender aromatherapy on pain, anxiety, and level of satisfaction associated with the peripheral venous cannulation (PVC) in patients undergoing surgery. One hundred and six patients undergoing surgery were randomized to receive aromatherapy with lavender essential oil (the lavender group) or a placebo (the control group) during PVC. The patients' pain, anxiety, and satisfaction scores were measured. There was no statistically significantly difference between the groups in terms of demographic data. After cannulation, the pain and anxiety scores (anxiety 2) of the patients in the lavender group were significantly lower than the control group (for p = 0.01 for pain scores; p < 0.001 for anxiety 2 scores). In addition, patient satisfaction was significantly higher in the lavender group than in the control group (p = 0.003). Lavender aromatherapy had beneficial effects on PVC pain, anxiety, and satisfaction level of patients undergoing surgery. Copyright © 2016 Elsevier Ltd. All rights reserved.

This study investigated the effects of dexmedetomidine on heart-type fatty acid binding protein (H-FABP), creatine kinase isoenzymes (CK-MB), and troponin I (cTnI) levels, neurological function and near-term prognosis in patients undergoing heart valve replacement. Patients undergoing heart valve replacement were randomly allocated to remifentanil anesthesia (control group, n=48) or dexmedetomidine anesthesia (observation group, n=48). Hemodynamic parameters were measured before anesthesia induction (T1), 1 min after intubation (T2), 10 min after start of surgery (T3), and on completion of surgery (T4). Levels of plasma H-FABP, CK-MB and cTnI were measured 10 min before anesthesia induction (C1), 10 min after start of surgery (C2), on completion of surgery (C3), 6 h after surgery (C4), and 24 h after surgery (C5). S100β protein and serum neuron-specific enolase (NSE) were detected 10 min before anesthesia induction (C1), and 24 h after surgery (C5). Neurological and cardiac function was evaluated 24 h after surgery. Incidence of cardiovascular adverse events was recorded for 1 year of follow-up. There were no significant differences in the average heart rate between the two groups during the perioperative period. The mean arterial pressure in the observation group was significantly lower than control group (P<0.05). Levels of H-FABP, CK-MB and cTnI at C2, C3, C4 and C5, were significantly higher than C1, but significantly lower in the observation versus control group (P<0.05). Twenty-four hours after surgery, levels of S100β and NSE in both groups were higher than those before induction (P<0.05), but significantly lower in the observation versus control group (P<0.05). Twenty-four hours after surgery, neurological function scores were better, and myocardial contractility and arrhythmia scores significantly lower in the observation versus control group (P<0.05 for all). After follow-up for 1 year, incidence of cardiovascular adverse events was significantly lower in the observation versus control group (P<0.05). Dexmedetomidine anesthesia can effectively maintain hemodynamic stability, reduce myocardial injury and the occurrence of cognitive dysfunction, and improve prognosis in patients undergoing heart valve replacement.

Resection quality after robot-assisted surgery for colorectal cancer have not previously been investigated in a nationwide study. The aim of the study was to examine the resection quality in robot-assisted versus laparoscopic surgery for colorectal cancer. Furthermore, 30-day mortality, postoperative complications, and conversion to open surgery were investigated. Patients undergoing either laparoscopic or robot-assisted surgery for colorectal cancer between 1 January 2010 and 31 December 2015 were included. The primary outcome was whether R0 resection was achieved. Secondary outcomes were 30-day mortality, postoperative complications, and conversions to laparotomy. A total of 8615 and 3934 patients had a diagnosis of colon cancer and rectal cancer respectively. Of the patients with colon cancer, 511 patients underwent robot-assisted surgery and of the patients with rectal cancer, 706 patients underwent robot-assisted surgery. In the multivariate analysis, patients with colon cancer had an odds ratio (OR) = 0.63 (95%CI 0.45-0.88) for receiving R0 resection in the robot-assisted group compared to laparoscopy. For patients with rectal cancer, the OR was 1.20 (95%CI 0.89-1.61). No difference in 30-day mortality or postoperative complications were observed. The OR of conversion to laparotomy was lower in the robot-assisted group compared to the laparoscopic group in both patients with colon - and rectal cancer. The study showed significant lower odds of receiving R0 resection in patients with colon cancer undergoing robot-assisted surgery. In patients with rectal cancer the robot-assisted surgery non-significantly increased the odds of receiving R0 resection. Copyright © 2018 Elsevier Ltd. All rights reserved.

Aim: Resection surgery on the colon and rectum are changing both anatomical and physiological relations within the abdominal cavity. Delayed functions of the gastrointestinal tract, flatulence, failure of peristalsis, prolonged spasms and pain, limited postoperative recovery of these patients increase the overall cost of treatment. Early consumption of coffee instead of tea should lead to faster restoration of normal function of the colon without unwanted negative repercussions. Method: This study is designed as a prospective-retrospective clinical study and was carried out at the Surgery Center Tuzla, during the year 2013/ 2014. Sixty patients were randomized in relation to the type of resection surgery, etiology of disease-malignant benign, and in relation to whether they were coffee users or not. Patients were divided into two groups. The first group of thirty patients was given 100 ml of instant coffee divided into three portions right after removing the nasogastric tube, first postoperative day, while the second group of thirty patients got 100 ml of tea. Monitored parameter was: time of first stool and the second group of monitored parameters was: whether there was returning of nasogastric tube or not, increased use of laxatives, whether there was anastomotic leak, radiologic and clinical dehiscence, audit procedures, or lethal outcomes in the treatment of patients. Results: A total of 61 patients were randomized into two groups of 30 int he group of tea and coffee 29 in the group, two patients were excluded from the study because they did not consume coffee before surgery. Time of getting stool in the postoperative period after elective resection surgery on the colon and rectum is significantly shorter after drinking coffee for about 15h (p <0.01). Also, the length of hospital stay was significantly shorter after drinking coffee (p <0.01). Time of hospitalization in subjects/respondents coffee consumers on average lasted 8.6 days with consumers of tea for 16 days. The incidence of postoperative complications was significantly lower after consumption of coffee (p <0.05). Conclusion: Postoperative consumption of coffee is a safe and effective way to accelerate the establishment of the bowel function after colorectal resection surgery. PMID:26843724

The increased intracranial pressure can significantly complicate the perioperative period in major abdominal surgery, increasing the risk of complications, the length of recovery from the surgery, worsening the outcome. Epidural anesthesia has become a routine component of abdominal surgery, but its use in patients with increased intracranial pressure remains controversial. The goal of the study was to evaluate the safety and efficacy of epidural anesthesia, according to monitoring of intracranial pressure in patients with increased intracranial pressure. The study includes 65 surgical patients who were routinely undergone the major abdominal surgery under combined epidural/general anesthesia. Depending on the initial ICP all patients were divided into 2 groups: 1 (N group) - patients with the normal intracranial pressure (≤12 mm Hg, n = 35) and 2 (E group) - patients with the elevated intracranial pressure (ICP > 12 mm Hg, n = 30). During the surgery we evaluated ICP, blood pressure, cerebral perfusion pressure (CPP). The parameters of recovery from anesthesia and the effectiveness of postoperative analgesia were also assessed. In N group ICP remained stable. In E group ICP decreased during anesthesia, the overall decline was 40% at the end of the operation (from 15 to 9 mm Hg (P <0.05)). The correction of MAP with vasopressors to maintain normal CPP was required mainly in patients with increased ICP (70% vs. 45%, p <0.05). CPP declined by 19% in N group. In E group the CPP reduction was 23%, and then it remained stable at 60 mm Hg. No significant differences in time of the recovery of consciousness, effectiveness of postoperative analgesia and complications between patients with initially normal levels of ICP and patients with ICH were noted. The combination of general and epidural anesthesia is safe and effective in patients with increased intracranial pressure undergoing elective abdominal surgery under the condition of maintaining the arterial pressure. Its use is not associated with the increase in intracranial pressure during the anesthesia, but it needs an intraoperative monitoring of ICP in order to prevent CPP reduction.

To determine the efficacy of topical 0.3% ciprofloxacin in reducing conjunctival biota in patients undergoing cataract surgery. Experimental, prospective, randomized, controlled and single-blind study. Forty-six eyes of 46 patients were randomized into 2 groups, the study group (n=23) received topical 0.3% ciprofloxacin one day before surgery for six times, and on the day of the surgery one drop every 15minutes starting one hour before surgery until 3 doses were completed. The control group (n=23) did not receive any antibiotics. For both groups for the surgical field 10% povidone-iodine was applied. Samples from the conjunctiva were taken at four different times and then cultured on solid media (chocolate agar, blood agar) and enrichment broth (thioglycolate). The aqueous humor samples were also cultured in thioglycolate. The presence of bacteria was identified quantitatively and qualitatively, and the frequency of contamination was measured by considering the presence of bacteria in liquid and solid culture media. The number of colony forming units (CFU) was counted in the solid culture medium. Positive cultures were obtained in 82.6% and 78.2% of the patients in the study and control groups, respectively, before the administration of 0.3% ciprofloxacin. The administration of 0.3% ciprofloxacin significantly reduced the CFU compared to the control group (P<.05). Immediately after the use of povidone-iodine, the proportion of patients with a positive culture decreased to 21.7% in the study group, and 8.7% in the control group. At the end of the surgery, this percentage was 26% and 30.4%, respectively. The most common isolated pathogen was negative-coagulase Staphylococcus (66.7%). The administration of 0.3% ciprofloxacin reduces conjunctival bacterial load in the preoperative period. However, it was unable to eradicate the bacteria completely. The administration of povidone-iodine reduced conjunctival biota in 50%-70% of patients undergoing cataract surgery. Copyright © 2012 Sociedad Española de Oftalmología. Published by Elsevier Espana.

The aim of the present study was to evaluate the effects of femtosecond laser-assisted cataract surgery (FLACS) and phacoemulsification on corneal biomechanics using corneal visualization Scheimpflug technology. The medical records of 50 eyes from 50 patients who received phacoemulsification and intraocular lens implantation because of age-related factors between June 2014 and September 2014 were retrospectively analyzed. FLACS was used in 12 eyes (FLACS group), and conventional phacoemulsification in 38 eyes (PHACO group). The evaluation of corneal biomechanical parameters included the first/second applanation time (A-time1/A-time2), the first/second applanation length (A-length1/A-length2), corneal velocity during the first/second applanation moment (Vin/Vout), highest concavity time, highest concavity-radius (HC-radius), peak distance (PD), deformation amplitude (DA), central corneal thickness (CCT), and intraocular pressure (IOP). The differences in A-length1/A-length2, IOP, CCT, PD, and DA were significant in the PHACO group between those before, 1 week after, and 1 month after surgery. No significant differences in corneal biomechanical parameters were found between those at 1 month after surgery and before surgery. There were significant differences in IOP and CCT in the FLACS group between those before, 1 week after, and 1 month after surgery. There were no significant differences in the other corneal biomechanical parameters. No significant differences were found in corneal biomechanical parameters between those 1 month after surgery and before surgery. There were significant differences in A-length1/A-length2, CCT, PD, and DA between the two groups at 1 week after surgery. There were no significant differences in corneal biomechanical parameters between the two groups at 1 month after surgery. In conclusion, the effect of FLACS on corneal biomechanics is smaller than that of phacoemulsification. The corneal biomechanical parameters are restored to preoperative levels with the healing of the incision, and the reduction of swelling of the tissue near the incision.

The aim of this survey study was to assess the influence of chin prominence on the perception of profile esthetics between genders by orthodontists, oral and maxillofacial surgeons (OMF), plastic surgeons, orthognathic patients and laypersons. A total of 731 observers participated in this study. Profile photographs of one female and one male showing ideal soft tissue values, skeletal class 1 relationship, and normodivergent facial type were modified with photo editing program (Adobe Photoshop CC software), so that the chin was moved posteriorly up to 10 mm and anteriorly up to 8 mm at 2-mm intervals. Participants were asked to rate 11 female and 11 male profile images and to assess whether surgery was needed. Within the limits of this study, ideal, slightly concave and slightly convex profiles for females, and ideal and slightly concave profiles for males were found more acceptable. Surgery was desired for 50.9% of retrusive profiles and 57.3% of protrusive profiles. Female participants had a higher rate of desire for surgery than male participants, and clinicians desired surgery significantly less than others. Desire for surgery started from 4 mm in males and females for all groups, from -6 mm in orthodontists and OMFs, from -4 mm in other groups in females, and from -6 mm in males for all groups. Clinicians tend to operate more pronounced cases when compared to laypeople. A significantly higher rate of surgery was desired for protrusive chin profiles, and female participants had a higher desire for surgery.

Various devices have been recently employed for percutaneous closure of the patent ductus arteriosus (PDA). Although the high effectiveness of device closure techniques has been clearly determined, a few studies have focused on the cost-effectiveness and also postoperative complications of these procedures in comparison with open surgery. The present study aimed to evaluate the clinical outcome and cost-effectiveness of PDA occlusion by Amplatzer and coil device in comparisong with open surgery. In this cross-sectional study, a randomized sample of 201 patients aged 1 month to 16 years (105 patients with device closure and 96 patients with surgical closure) was selected. The ratio of total pulmonary blood flow to total systemic blood flow, the Qp/Qs ratio, was measured using a pulmonary artery catheter. The cost analysis included direct medical care costs associated with device implantation and open surgery, as well as professional fees. All costs were calculated in Iranian Rials and then converted to US dollars. There was no statistical difference in mean Qp/Qs ratio before the procedure between the device closure group and the open surgery group (2.1 ± 0.7 versus 1.7 ± 0.6, P = 0.090). The mean measured costs were overall higher in the device closure group than in open closure group (948.87 ± 548.76 US$ versus 743.70 ± 696.91 US$, P < 0.001). This difference remained significant after adjustment for age and gender (Standardized Beta = 0.160, P = 0.031). PDA closure with the Amplatzer ductal occluder (1053.05 ± 525.73 US$) or with Nit-Occlud coils (PFM) (912.73 ± 565.94 US$, P < 0.001) was more expensive than that via open surgery. However, the Cook detachable spring coils device closure (605.65 ± 194.62 US$, P = 0.650) had a non-significant cost difference with open surgery. No event was observed in the device closure group regarding in-hospital mortality or morbidity; however, in another group, 2 in-hospital deaths occurred, two patients experienced pneumonia and seizure, and one suffered electrolyte abnormalities including hyponatremia and hypocalcemia. Although open surgery seems to be less expensive than device closure technique, because of lower mortality and morbidity, the latter group is more preferable.

To determine if preoperative statin treatment is associated with a reduction in systemic inflammatory response (SIR) and myocardial damage markers following cardiac surgery with cardiopulmonary bypass (CPB). We study a prospective cohort of 138 patients who underwent coronary and valvular surgery with CPB. We differentiate two study groups: patients with (group A, n=72) or without (group B, n=66) statins. Plasma levels of pro-inflammatory interleukins (tumour necrosis factor-alpha (TNF-alpha), interleukin (IL)-6, IL-8 and IL-2R), creatine phosphokinase (CPK), CPK-MB and troponin I were measured before and 1, 6, 24 and >72 h after surgery. The baseline, operative and postoperative morbidity and mortality characteristics were similar for both the groups. Group A had significantly lower postoperative levels of IL-6 than group B at 6h (68.8+/-5 pg ml(-1) vs 108.9+/-108 pg ml(-1), p=0.01), 24h (71.7+/-7 pg ml(-1) vs 110.4+/-106 pg ml(-1), p=0.01) and before hospital discharge (21.6+/-12 pg ml(-1) vs 32.8+/-27 pg ml(-1), p=0.005), as well as significantly lower average IL-6 levels in the first 24h following surgery (71.8+/-5 pgml(-1) vs 112.8+/-82 pg ml(-1), p=0.002). The postoperative CPK-MB at 24h (19.7+/-23 ng ml(-1) vs 33.1+/-32 ng ml(-1), p=0.02) and troponin I levels at the end of the intervention (2.2+/-2.2 ng ml(-1) vs 3.3+/-3.1 ng ml(-1), p=0.03) and at 24h (4.1+/-3.5 ng ml(-1) vs 6.6+/-8 ng ml(-1), p=0.04) were also significantly lower in the group treated with statins prior to surgery. Preoperative treatment with statins is associated with a lower biochemical parameters of SIR and myocardial damage following cardiac surgery with CPB, regardless of it being coronary bypass grafting (CABG) or valvular surgery.

Cardiovascular diseases have the highest death rates in human society. Coronary artery disease is among the most important of these diseases. No treatment of cardiovascular disease has as much impact on the quality of life of the patients as the heart surgery. The recovery from heart surgery is associated with symptoms of pain and psychological distress. In the early recovery period, the patients will face moderate symptoms of anxiety and depression. In this regard, various measures of nursing, as complementary therapy practices have been performed to help the patients for overcoming the physical and psychological needs. One of these methods, in recent years has been the use of complementary and alternative therapies, particularly massage therapy, after heart surgery. Thus, the aim of this study was to determine the effectiveness of massage therapy on the mood of patients after open-heart surgery in Isfahan Chamran Hospital during 2010-11. In this study 72 patients, who underwent coronary artery bypass surgery, were selected. They were randomly assigned to the two case and control groups. The patients of the case group (n = 36) received Swedish massage for 20 minutes in 4 sessions in 4 consecutive days, 3 to 6 days after the open-heart surgery. The patients in the control group received only the routine care. The mood questionnaire (POMS) which was used in this study has been completed the day before the start of the study and intervention and again after the last day of the intervention. SPSS software version 12 and descriptive and inferential statistical methods were used for data analysis. The comparison of study results showed that massage decreased the overall rating of the patients' mood after the surgery. The use of massage therapy as an effective nursing intervention can improve the patients' mood after open-heart surgery. Due to the low cost and simplicity of this method, it can perhaps be used as a complement to drug therapy and postoperative interventions used in these patients.

Open heart surgery is associated with high occurrence of atrial fibrillation (AF), subsequently increasing the risk of post-operative ischemic stroke. Concomitant with open heart surgery, a cardiac ablation procedure is commonly performed in patients with known AF, often followed by left atrial appendage closure with surgery (LAACS). However, the protective effect of LAACS on the risk of cerebral ischemia following cardiac surgery remains controversial. We have studied whether LAACS in addition to open heart surgery protects against post-operative ischemic brain injury regardless of a previous AF diagnosis. One hundred eighty-seven patients scheduled for open heart surgery were enrolled in a prospective, open-label clinical trial and randomized to concomitant LAACS vs. standard care. Randomization was stratified by usage of oral anticoagulation (OAC) planned to last at least 3 months after surgery. The primary endpoint was a composite of post-operative symptomatic ischemic stroke, transient ischemic attack or imaging findings of silent cerebral ischemic (SCI) lesions. During a mean follow-up of 3.7 years, 14 (16%) primary events occurred among patients receiving standard surgery vs. 5 (5%) in the group randomized to additional LAACS (hazard ratio 0.3; 95% CI: 0.1-0.8, p = 0.02). In per protocol analysis (n = 141), 14 (18%) primary events occurred in the control group vs. 4 (6%) in the LAACS group (hazard ratio 0.3; 95% CI: 0.1-1.0, p = 0.05). In a real-world setting, LAACS in addition to elective open-heart surgery was associated with lower risk of post-operative ischemic brain injury. The protective effect was not conditional on AF/OAC status at baseline. LAACS study, clinicaltrials.gov NCT02378116 , March 4th 2015, retrospectively registered.

The aim of this study was to examine the effects of preoperative carprofen on the cardiorespiratory, hormonal and metabolic stress response during umbilical surgery under isoflurane anaesthesia combined with local anaesthesia, in calves. A randomised, blinded experimental study was conducted in 24 calves. Carprofen (n = 12; 1.4 mg/kg) or physiological saline solution (controls; n = 12) was administered 1 h prior to surgery. Anaesthesia was induced with xylazine (0.1 mg/kg, IM) and, after the onset of sedation (i.e. after 5-8 min), ketamine was administered (2 mg/kg, IV). Anaesthesia was then maintained with isoflurane (ISO) in oxygen to effect and completed by infiltration of the incision line with 20 mL of 2% procaine. Cardiorespiratory, endocrine and metabolic parameters were examined before, during and after surgery at short intervals. In both groups, anaesthesia appeared adequate for the surgical intervention. Heart rate, stroke index and arterial blood pressure were significantly elevated after the onset of surgery. Oxygen partial pressure and oxygen delivery increased, while the oxygen extraction ratio decreased intraoperatively, ensuring sufficient oxygen supply. In the control group, the mean surge in serum cortisol concentrations tended to be higher (P = 0.089) and systemic vascular resistance (SVR) was significantly greater (P <0.05) than in the carprofen group during surgery. In conclusion, the anaesthetic protocol used in this study induced reliable analgesia in both groups. The lower serum cortisol levels and SVR may indicate a reduced surgical stress response in calves undergoing umbilical surgery under ISO anaesthesia after administering carprofen preoperatively.

To examine the analgesic and opioid-sparing effects of parecoxib following major gynecologic surgery. This is a large subset analysis of patients from a multicenter, randomized, double-blind, placebo-controlled study of parecoxib/valdecoxib (PAR/VAL) for postoperative pain. Pain severity, pain interference with function, opioid use, occurrence of opioid-related symptoms, and Patient/Physician Global Evaluation of Study Medication were compared between placebo and PAR/VAL treatment groups in the days following surgery. Pain scores were reduced in the PAR/VAL group (n=98), relative to placebo (n=97), on Day 2 (-21%, P <0.001) and Day 3 (-23%, P =0.004). Pain interference with function scores were also significantly lower in the PAR/VAL group, compared with placebo, on Day 2 (-29%, P <0.001) and Day 3 (-28%, P =0.013). Consumption of supplemental morphine was significantly lower in the PAR/VAL group relative to placebo at 24 hours (-37%, P =0.010) and trended lower at 48 (-28%) and 72 hours (-26%). Patients in the PAR/VAL group also had a reduced risk of experiencing specific opioid-related symptoms, including "inability to concentrate" (relative risk =0.53) and "nausea" (relative risk =0.60) on Day 2. Both Patient and Physician Global Evaluation of Study Medication scores were better in the PAR/VAL group than in the placebo group. The current study adds support for the use of parecoxib in patients following major gynecologic surgery.

Relevant reports about oral candidiasis status and prevention measures after free flap surgery for the oral and maxillofacial region are limited. The present study explored oral candidiasis status after free flap surgery and its prevention through a prospective comparative study. One hundred four patients were randomized to a control group (n = 54) and an experimental group (n = 50). Compared with the control group, the experimental group was provided an additional 3% sodium bicarbonate saline solution for oral care after free flap surgery. The incidence of oral candidiasis was evaluated by objective examination (saliva culture and salivary pH measurement) and subjective evaluation (clinical signs of oral candidiasis) at admission and from postoperative days 1 to 14. The salivary pH values of the 2 groups were lower than the normal salivary pH, and postoperative salivary pH values were always lower than the active range of oral lysozymes in the control group. The salivary pH values of the experimental group were higher than those of the control group from postoperative days 6 to 14 (P < .05). The incidence of oral candidiasis was 13.0% in the control group, which was higher than that in the experimental group (2.0%; P < .05). In addition, advanced age, use of a free flap for the simultaneous repair of intraoral and paraoral defects, and a combination of 2 antibiotic types were risk factors for oral candidiasis. Oral candidiasis was common in patients after free flap reconstruction surgery, and the use of 3% sodium bicarbonate saline solution for oral care effectively prevented it.

Trial design neuroinflammation and postoperative pain after surgery are increasingly reported in association with postoperative cognitive dysfunction (POCD). Parecoxib, a selective cyclooxygenase (COX)-2 inhibitor, is used for postoperative analgesia for its potent anti-inflammatory and analgesic effects. This study aimed to evaluate parecoxib's effects on POCD in elderly patients undergoing total knee arthroplasty. Around 134 elderly patients undergoing total knee arthroplasty were randomly divided into parecoxib (group P) and control (group C) groups, and treated with parecoxib sodium and saline, respectively, shortly after induction of general anesthesia and 12-h postsurgery, respectively. Perioperative plasma IL-1β, IL-6, TNF-α, and C-reactive protein (CRP) 1evels were measured. Postoperative pain was assessed following surgery. Neuropsychological tests were performed before surgery, and 1 week and 3 months postoperation. POCD incidence in group P was significantly lower compared with that of group C at 1 week after surgery (16.7% vs 33.9%; P < 0.05); no significant difference was found between groups C and P at 3-month follow-up (9.7% vs 6.7%). Compared with group C values, visual analog pain scale (VAS) scores at 3, 6, and 12 hours after surgery were significantly lower in group P(P < 0.05). Plasma IL-1β, IL-6, and TNF-α levels were lower in group P than in group C after the operation (P < 0.05). No significant difference in the plasma CRP level was found between groups P and C. Parecoxib sodium decreases POCD incidence after total knee arthroplasty in elderly patients and may explain how this drug suppresses inflammation and acute postoperative pain caused by surgical trauma.

A retrospective study. To compare the mid-term outcomes of hybrid surgery and anterior cervical discectomy and fusion for the treatment of contiguous 2-segment cervical degenerative disc diseases. Hybrid surgery has become one of the most controversial subjects in spine communities, and the comparative studies of hybrid surgery and anterior cervical discectomy and fusion in the mid- and long-term follow-up are rarely reported. From 2009 to 2012, 42 patients who underwent hybrid surgery (n = 20) or anterior cervical discectomy and fusion (n = 22) surgery for symptomatic contiguous 2-level cervical degenerative disc diseases were included. Clinical and radiological records, including Japanese Orthopedic Association, Neck Disability Index, Visual Analogue Scale, local cervical lordosis and range of motion, were reviewed retrospectively. Complications were recorded and evaluated. Mean follow-up were 77.25 and 79.68 months in HS group and ACDF group, respectively (p > 0.05). Both in HS group and ACDF group, significant improvement for the mean JOA, NDI and VAS scores was found at 2-week postoperation and at the last follow-up (P < 0.05). However, there were no significant differences between the two groups (P > 0.05). At last follow-up, the ROM of superior adjacent segments in ACDF group was significantly larger than HS group (p < 0.05) while the ROM of C2-C7 was significantly smaller (p < 0.05). In HS group, 2(10%)sagittal wedge deformity, 1(5%) heterotopic ossification and 1(5%) anterior migration of the Byran disc prosthesis were found. No symptomatic adjacent segment degeneration occurred in two groups. Hybrid surgery appears to be an acceptable option in the management of contiguous 2-segment cervical degenerative disc diseases. It yielded similar mid-term clinical improvement to anterior cervical discectomy and fusion, and demonstrated better preservation of cervical ROM. The incidence of postoperative sagittal wedge deformity was low, however, it can significantly reduce the cervical lordosis. 4.

Arthroscopic surgery in borderline dysplastic hips remains controversial, but the role of the ligamentum teres (LT) has not been studied in this setting. Borderline dysplastic patients with LT tears have worse short-term outcomes than those without LT tears. Cohort study; Level of evidence, 3. Data were prospectively collected on patients who underwent arthroscopic surgery between February 2008 and April 2014. The inclusion criteria were borderline dysplasia (lateral center-edge angle [LCEA], 18°-25°) and labral tears; arthroscopic treatments including labral preservation and capsular plication; and preoperative patient-reported outcome scores including the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score-Sport-Specific Subscale, and visual analog scale for pain. Patients were excluded for preoperative Tönnis osteoarthritis grade >0, workers' compensation claims, previous ipsilateral hip surgery and conditions, or frank dysplasia (LCEA <18°). Patients with LT tears were pair-matched to patients without tears for sex, age at surgery ±10 years, body mass index (<30 kg/m 2 vs ≥30 kg/m 2 ), labral treatment type, and microfracture. Of 68 eligible patients, 63 (93%) had a minimum 2-year follow-up, and 30 (48%) had LT tears. Twenty patients in each group were pair-matched. The mean follow-up time was 54.3 months (range, 24.2-83.8 months) for the LT tear group and 38.6 months (range, 24.6-70.6 months) for the control group ( P = .002). Ninety percent were female. There were no significant differences regarding demographics or intra-operative procedures. The LT tear group trended toward lower postoperative mHHS ( P = .09) and NAHS ( P = .09) values. Mean satisfaction was 8.1 for the LT tear group and 7.9 for the control group. Preoperative and follow-up scores were not significantly different between the groups. The LT tear group had 5 revisions, with 1 revision in the control group. Three patients (15%) in the LT tear group underwent total hip arthroplasty (THA); no patients in the control group required THA. In borderline dysplastic patients undergoing hip arthroscopic surgery with labral treatment and capsular plication, LT tears may indicate advanced instability and portend slightly inferior outcomes when compared with a match-controlled group. Borderline dysplastic patients with LT tears may have increased propensities toward revision arthroscopic surgery and conversion to THA. LT tears in these patients may warrant consideration for additional procedures including periacetabular osteotomy and LT reconstruction.

Abstract: Circulatory arrest during aortic surgery presents a risk of neurological complications. The present study aimed to investigate the effectiveness of deep hypothermic circulatory arrest (DHCA) vs. antegrade cerebral perfusion (ACP) in cerebral protection during the surgical treatment of chronic dissection of the ascending and arch aorta and to assess the quality-of-life (QoL) in the long-term postoperative period with respect to the used cerebral protection method. In a prospective, randomized study, 58 patients with chronic type I aortic dissection who underwent ascending aorta and aortic arch replacement surgery were included. Patients were allocated in two groups: 29 patients who underwent surgery under moderate hypothermia (24°C) combined with ACP and 29 patients who underwent surgery under DHCA (18°C) with craniocerebral hypothermia. The regional hemoglobin oxygen saturation (rSO2, %) were compared during surgery, neurological complications were analyzed during the early postoperative period, QoL was compared in the long-term postoperative period (1-year follow-up). During the early postoperative period, 37.9% of patients in the DHCA group exhibited neurological complications, compared with 13.8% of those in the ACP group (p < .05). The risk of neurological complications in the early postoperative period was dependent on the extent of rSO2 decrease during circulatory arrest. In the ACP group, rSO2 decreased by ≤17% from baseline during circulatory arrest. In the DHCA group, a more profound decrease in rSO2 (>30%) was recorded (p < .05). QoL in the long-term period after surgery improved, but it was not dependent on the cerebral protection method used during surgery. ACP during aortic replacement demonstrated the most advanced properties of cerebral protection that can be evidenced by a lesser degree of neurological complications, compared with patients who underwent surgery under conditions of DHCA. QoL after surgery was not dependent on the cerebral protection method used during surgery. PMID:28298661

A total of 99 patients with head and neck cancer who were to undergo surgery were randomized in a prospective comparative study of sulbactam-ampicillin (1:2 ratio; four doses of 3 g of ampicillin and 1.5 g of sulbactam intravenously [i.v.] every 6 h) versus clindamycin (four doses of 600 mg i.v. every 6 h)-amikacin (two doses of 500 mg i.v. every 12 h) as prophylaxis starting at the induction of anesthesia. The two groups of evaluable patients (43 in the clindamycin-amikacin treatment group and 42 in the sulbactam-ampicillin treatment group) were comparable as far as age (mean, 57 years; range, 21 to 84 years), sex ratio (71 males, 28 females), weight (mean, 66 kg; range, 40 to 69 kg), indication for surgery (first surgery, 48 patients; recurrence, 37 patients), previous anticancer treatment (surgery, radiation therapy, chemotherapy), type of surgery, and stage of cancer. The overall infection rate (wound, bacteremia, and bronchopneumonia) within 20 days after surgery was 20 patients in each group. Wound infections occurred in 14 (33%) sulbactam-ampicillin-treated patients and 9 (21%) clindamycin-amikacin-treated patients (P = 0.19; not significant). The rates of bacteremia were 2 and 4%, respectively. The rates of bronchopneumonia were 14.3 and 23.2%, respectively (P was not significant). Most infections were polymicrobial, but strict anaerobes were recovered only from patients who received sulbactam-ampicillin. Antimicrobial treatment was required within 20 days after surgery for 42% of the sulbactam-ampicillin-treated patients and 44% of the clindamycin-amikacin-treated patients. By comparison with previous studies, we observed a decreased efficacy of antimicrobial prophylaxis in patients with head and neck cancer undergoing surgery because of the increased proportion of patients who were at very high risk for infection (extensive excision and plastic reconstruction in patients with recurrent stage III and IV cancers) and because of the longer duration of surgery.

Pancreatic ductal adenocarcinoma are known to metastasise early and a rationale exists for the investigation of preoperative chemotherapy in patients with resectable disease. We aimed to assess the role of combination chemotherapy in this setting in the PACT-15 trial. We did this randomised, open-label, phase 2-3 trial in ten hospitals in Italy. We report the phase 2 part here. Patients aged 18-75 years who were previously untreated for pancreatic ductal adenocarcinoma, with Karnofsky performance status of more than 60, and pathologically confirmed stage I-II resectable disease were enrolled. Patients were randomly assigned (1:1:1), with a minimisation algorithm that stratified treatment allocation by centre and concentrations of carbohydrate antigen 19-9 (CA19-9 ≤5 × upper limit of normal [ULN] vs >5 × ULN), to receive surgery followed by adjuvant gemcitabine 1000 mg/m 2 on days 1, 8, 15 every 4 weeks for six cycles (arm A), surgery followed by six cycles of adjuvant PEXG (cisplatin 30 mg/m 2 , epirubicin 30 mg/m 2 , and gemcitabine 800 mg/m 2 on days 1 and 15 every 4 weeks and capecitabine 1250 mg/m 2 on days 1-28; arm B), or three cycles of PEXG before and three cycles after surgery (arm C). Patients and investigators who gave treatments or assessed outcomes were not masked to treatment allocation. The primary endpoint was the proportion of patients who were event-free at 1 year. The primary endpoint was analysed in the per-protocol population. Safety analysis was done for all patients receiving at least one dose of study treatment. The trial is registered with ClinicalTrials.gov, number NCT01150630. Between Oct 5, 2010, and May 30, 2015, 93 patients were randomly allocated to treatment. One centre was found to be non-compliant with the protocol, and all five patients at this centre were excluded from the study. Thus, 88 patients were included in the final study population: 26 in group A, 30 in group B, and 32 in group C. In the per-protocol population, six (23%, 95% CI 7-39) of 30 patients in group A were event-free at 1 year, as were 15 (50%, 32-68) of 30 in group B and 19 (66%, 49-83) of 29 in group C. The main grade 3 toxicities were neutropenia (five [28%] of 18 in group A, eight [38%] of 21 in group B, eight [28%] of 29 in group C before surgery, and ten [48%] of 21 in group C after surgery), anaemia (one [6%] in group A, four [19%] in group B, eight [28%] in group C before surgery, and five [24%] in group C after surgery), and fatigue (one [6%] in group A, three [14%] in group B, two [7%] in group C before surgery, and one [5%] in group C after surgery). The main grade 4 toxicity reported was neutropenia (two [11%] in group A, four [19%] in group B, none in group C). Febrile neutropenia was observed in one patient (3%) before surgery in group C. No treatment-related deaths were observed. Our results provide evidence of the efficacy of neoadjuvant chemotherapy in resectable pancreatic ductal adenocarcinoma. Since the trial began, the standard of care for adjuvant therapy has altered, and other chemotherapy regimens developed. Thus, we decided to not continue with the phase 3 part of the PACT-15. We are planning a phase 3 trial of this approach with different chemotherapy regimens. PERLAVITA ONLUS and MyEverest ONLUS. Copyright © 2018 Elsevier Ltd. All rights reserved.

PubMed Central

Ince, Ilker; Aksoy, Mehmet; Celik, Mine

2016-01-01

Objective: Distal nerve blocks are used in the event of unsuccessful blocks as rescue techniques. The primary purpose of this study was to determine the sufficiency for anesthesia of distal nerve block without the need for deep sedation or general anesthesia. The secondary purpose was to compare block performance times, block onset times, and patient and surgeon satisfaction. Materials and Methods: Patients who underwent hand surgery associated with the innervation area of the radial and median nerves were included in the study. Thirty-four patients who were 18–65 years old and American Society of Anesthesiologists grade I–III and who were scheduled for elective hand surgery under conscious nerve block anesthesia were randomly included in an infraclavicular block group (Group I, n=17) or a radial plus median block group (Group RM, n=17). The block performance time, block onset time, satisfaction of the patient and surgeon, and number of fentanyl administrations were recorded. Results: The numbers of patients who needed fentanyl administration and conversion to general anesthesia were the same in Group I and Group RM and there was no statistically significant difference (p>0.05). The demographics, surgery times, tourniquet times, block perfomance times, and patient and surgeon satisfaction of the groups were similar and there were no statistically significant differences (p>0.05). There was a statistically significant difference in block onset times between the groups (p<0.05). Conclusions: Conscious hand surgery can be performed under distal nerve block anesthesia safely and successfully. PMID:28149139

The Effect of Preoperative Ketorolac on WBC Response and Pain in Laparoscopic Surgery for Endometriosis

PubMed Central

2005-01-01

Surgical stress causes changes in the composition of white blood cells (WBCs). Ketorolac is believed to have analgesic effects and to reduce the stress response and may therefore improve postoperative outcomes. The aim of this study was to assess the effect of preoperative ketorolac on the WBC subsets in patients who had laparoscopic surgery for endometriosis. Fifty patients who had laparoscopic surgery for endometriosis were randomly assigned to one of two groups: the ketorolac group (n = 25) received ketorolac 0.5 mg/kg before the induction of anesthesia, and the control group (n = 25) received saline. White cell count, differential, and pathology studies were done immediately after surgery, on postoperative day 1, and on postoperative day 3. We compared the baseline values within and between the two groups. We also assessed postoperative pain and side effects. The time that elapsed before the first patient request for analgesia, total meperidine dose and VAS (Visual Analog Scale) for postoperative pain were significantly lower in the ketorolac group than in the control group. Compared to the pre- surgical values, there was an increase in total WBC count and percentage of neutrophils, but a decrease in percentages of lymphocytes, monocytes, eosinophils, basophils, and leucocytes. Total WBC count, neutrophils, monocytes, eosinophils and leucocytes showed significant differences between the two groups. The incidences of postoperative side effects, such as nausea, dizziness, headache, and shoulder pain were not different between the groups. Preoperative ketorolac reduced postoperative pain and influenced the WBC response in laparoscopic surgery for endometriosis. PMID:16385658

Although postoperative eye patching is a common practice its background is not well known. Therefore the necessity of eye patching after cataract surgery in topical anesthesia from the medical point of view and the patients' subjective opinion was studied. In this prospective and randomized study 133 patients received after cataract surgery either no covering of the eye (group1), a transparent eye shield for four hours (group 2), an eye pad for four hours (group 3) or an eye pad until the next morning (group 4). Clinical findings were noted and local symptoms, such as pain, foreign body sensation, tearing and photophobia were documented on a visual analogue scale (0 - 10). Furthermore, a questionnaire concerning the subjective opinion was handed out to the patient. The clinical findings revealed no significant differences between the groups. The mean values for local pain were 0.94 +/- 1.56, for the foreign body sensation 1.41 +/- 2.02, for tearing 0.99 +/- 1.8 and for photophobia 1.05 +/- 1.99. Comparing the groups there was significantly more pain and foreign body sensation reported by the patients in group 3, who received eye patching for 4 hours. 91 % of the unpatched patients had no discomfort, whereas 53 % of the patients wearing an eye pad until the next morning considered it as unnecessary. After cataract surgery in topical anesthesia only mild symptoms were noted. There were no significant differences between the groups in the objective clinical findings and the subjective feeling. These results indicate that after cataract surgery eye patching could be unnecessary.

Current trends in pediatric cardiac surgery and anesthesiology include goal-directed allogeneic blood transfusion, but few studies address the transfusion of platelets and cryoprecipitate. We report a quality improvement initiative to reduce the transfusion of platelets and cryoprecipitate in infants having cardiac surgery with cardiopulmonary bypass (CPB). Data from 50 consecutive patients weighing four to ten kilograms having cardiac surgery with CPB were prospectively collected after the institution of a policy to obtain each patient's platelet and fibrinogen levels during the rewarming phase of CPB. Data from 48 consecutive patients weighing four to ten kilograms having cardiac surgery with CPB prior to the implementation of the policy change were retrospectively collected. Demographics, laboratory values and blood product transfusion data were compared between the groups, using the Chi-square/Fisher's exact test or the T-Test/Wilcoxon Rank-Sum test, as appropriate. The results showed more total blood product exposures in the control group during the time from bypass through the first twenty-four post-operative hours (median of 2 units versus 1 unit in study group, p=0.012). During the time period from CPB separation through the first post-operative day, 67% of patients in the control group received cryoprecipitate compared to 32% in the study group (p=0.0006). There was no difference in platelet exposures between the groups. Checking laboratory results during the rewarming phase of CPB reduced cryoprecipitate transfusion by 50%. This reproducible strategy avoids empiric and potentially unnecessary transfusion in this vulnerable population. © The Author(s) 2016.

Recent studies suggest that preemptive analgesia may be effective in reducing postoperative pain. One physiologic explanation may be interference with the endogenous opioid response. We investigated whether long-lasting preoperative preemptive analgesia may have an effect on the hormonal stress response after total hip replacement. 42 patients scheduled for elective hip replacement for coxarthrosis were randomized to receive, on the day before the operation, either 5 ml*h(-1) ropivacaine 0.2% (study group, n = 21) or 5 ml*h(-1) saline (control group, n = 21). Postoperative analgesia was achieved in both groups by patient-controlled epidural analgesia (PCEA) with ropivacaine 0.2%. The main outcome measure was the concentration of authentic beta-endorphin [1-31] in plasma up to 4 days after surgery. Additional parameters included concentrations of adrenocorticotrope hormone and cortisol. Both groups were comparable concerning preoperative parameters and pain scores. Epidural blocks were sufficient in all patients for operative analgesia. Preemptive analgesia was performed for 11-20 hours in both groups and led to significantly decreased pain scores before surgery. Preemptive analgesia with epidural ropivacaine did not lead to decreased concentrations of beta-endorphin [1-31] before the start of surgery or in the postoperative period. Furthermore, no differences could be detected in the time course of beta-endorphin and adrenocorticotrope hormone after surgery. However, cortisol concentrations differed significantly between groups before the operation, but showed a comparable rise after surgery. Differences in postoperative pain after preemptive analgesia do not seem to be due to an altered endogenous opioid response.

The da Vinci Table Motion (dVTM) is a new device that enables patients to be repositioned with instruments in place within the abdomen, and without undocking the robot. The present study was designed to compare operative and short-term outcomes of patients undergoing colorectal cancer surgery with the da Vinci Xi system, with or without use of the dVTM. Ten patients underwent robotic colorectal resection for cancer with the use of dVTM (Xi-dVTM group) between May 2015 and October 2015 at our center. The intraoperative and short-term clinical outcome were compared, using a case-control methodology (propensity scores approach to create 1:2 matched pairs), with a similar group of patients who underwent robotic colorectal surgery for cancer without the use of the dVTM device (Xi-only group). Overall robotic operative time was shorter in the Xi-dVTM group ( P = .04). Operations were executed fully robotic in all Xi-dVTM cases, while 2 cases of the Xi-only group required conversion to open surgery because of bulky tumors and difficult exposure. Postoperative medical complications were higher in the Xi-only group ( P = .024). In this preliminary experience, the use of the new dVTM with the da Vinci Xi in colorectal surgery, by overcoming the limitations of the fixed positions of the patient, enhanced the workflow and resulted in improved exposure of the operative field. Further studies with a greater number of patients are needed to confirm these benefits of the dVTM-da Vinci Xi robotically assisted colorectal surgery.

We aimed to examine the effects of bariatric surgery on microvascular complications in patients with type 2 diabetes using objective measures. Prospective case-control study of 70 obese surgical patients with type 2 diabetes undergoing gastric bypass surgery matched for age, sex and duration of diabetes to 25 medical patients treated using international guidelines. Microvascular complications were assessed before and 12-18 months after intervention using urine albumin creatinine ratio (ACR) measurements, two-field digital retinal images and peripheral nerve conduction studies (in the surgical group only). Urine ACR decreased significantly in the surgical group but increased in the medical group. There were no significant differences between the surgical and medical groups in the changes in retinopathy. There were no changes in the nerve conduction variables in the surgical group. In the short term, bariatric surgery may be superior to medical care in the treatment of diabetic nephropathy, but not retinopathy or neuropathy.

To evaluate the efficacy and safety of intracameral lidocaine in cataract surgery compared to peribulbar anesthesia. A prospective, randomized, controlled study. A total of 200 consecutive cataract patients (200 eyes) participated. Eyes were randomly assigned to two groups: one group received 0.15 ml intracameral 1% unpreserved lidocaine combined with topical anesthesia (oxybuprocaine); the other group received 6 ml prilocaine peribulbar before phacoemulsification with sclerocorneal tunnel incision. Duration of surgery was measured; implicit time and amplitudes of the b-waves of the photopic electroretinogram (ERG) potentials (single-flash ERG and the 30-Hz flicker ERG) were recorded; frequencies of intraoperative problems, complications, intraoperative, and postoperative pain were evaluated. After lidocaine anesthesia combined with topical anesthesia, similar complications were found, longer operation time (P < 0.001), and significantly better visual acuity immediately after surgery (P < 0.001). The ERG amplitudes were not significantly reduced after 0.15-ml intracameral lidocaine half an hour after surgery (P > 0.05). Intracameral lidocaine 1% combined with topical anesthesia can be recommended as an alternative procedure to peribulbar anesthesia in cataract surgery with corneoscleral tunnel incision.

The objective of this study is to investigate the influences of percutaneous nephrolithotomy (PNL) and open surgery nephrolithotomy on the systemic stress response, SIRS and renal function. Forty patients with kidney calculi were enrolled in the study. Twenty cases were randomized to the PNL group and the other twenty cases to the open surgery group. Levels of C-reactive protein (CRP), interleukin-6(IL-6), β(2)-microglobulin (β(2)-MG), respiration rate, heart rate, body temperature and white blood cell counts were examined. CRP and IL-6 were measured in all patients pre-operatively and on post-operative days 1, 3 and 6, respectively. There was significant difference in their pre- and post-operation levels (P < 0.05), with the peak of CRP and IL-6 observed at post-operative days 3 and 1, respectively. There was significant difference in both CRP and IL-6 between the two groups (P < 0.05). At post-operative day 1, there were 5 cases of SIRS in PNL group and 12 cases in open surgery group; there was significant difference between the two groups (P < 0.05). Serum β(2)-MG levels were measured as the same time as CRP and no significant changes were observed within or between the groups (P > 0.05). Urine β(2)-MG levels were also measured. There was significant difference between pre- and the first day post-PNL (P < 0.05); there was no significant difference between pre- and the third and sixth day post-PNL (P > 0.05). There was significant difference between pre- and first and third day post-open surgery (P < 0.05); but there was no significant difference between pre- and the sixth day post-open surgery (P > 0.05). There was significant difference between two groups at the first, third and sixth days (P < 0.05). The systemic stress response is activated both in PNL group and open surgery group to some extent. The degree of stress response of PNL is lower than that of open surgery, proving the advantages of PNL with reference to serum immunology. There were cases in both the groups with SIRS, but the degree of SIRS in PNL group was lesser than the other group. Both the groups have no obvious effect on glomerular filtration function after operation and have effect on renal tubular reabsorption in the early stage after operation; but the recovery of the PNL group is faster than the open surgery group. It is thus shown that PNL is much safer and more feasible and has lesser effect on renal function.

Minimized extracorporeal circulation (MECC) is a promising alternative to standard extracorporeal circulation (ECC) and its use is increasing in routine coronary bypass surgery. We analyzed the clinical outcome of patients with reduced left ventricular function who underwent coronary artery bypass surgery with MECC or with standard ECC. From January 2003 to September 2008, 238 patients with a left ventricular function < 30 % underwent bypass surgery with ECC or MECC. The primary end point of our retrospective observational study was 30-day mortality. Secondary endpoints were the transfusion requirements, as well as intensive care and the in-hospital course. Demographic data, comorbidities and left ventricular function were similar in the study groups. MECC patients had a tendency towards a lower 30-day mortality rate, a better postoperative renal function and reduced ventilation times. Extracorporeal circulation time and postoperative high-dose inotropic support were significantly lower in the MECC group, while the stays in the intensive care unit and in hospital were comparable between the two groups. In our study, age in the ECC group, and previous infarction and New York Heart Association grade IV in the MECC group were preoperative risk factors associated with a higher mortality. Coronary bypass surgery using MECC is feasible and safe for patients with severely impaired left ventricular function. It is a promising alternative to ECC with a low mortality rate and a more favorable postoperative course.

To compare the efficacy and safety of ketorolac 0.5% ophthalmic solution with its vehicle in the treatment of ocular inflammation after cataract surgery and intraocular lens implantation. Multicenter clinical study. One hundred four patients were prospectively randomized, 52 patients in treatment group, 52 patients in control group. Patients received either ketorolac or vehicle four times daily in the operated eye for 14 days starting the day after surgery in a prospective, double-masked, randomized, parallel group study. Only patients with moderate or greater postoperative inflammation the day after surgery were enrolled. The main outcome measures include inflammation (cell, flare, ciliary flush), intraocular pressure and visual acuity. Ketorolac was significantly more effective than vehicle in reducing the manifestations of postoperative ocular inflammation, including: anterior chamber cells (P: = 0.002) and flare (P: = 0.009), conjunctival erythema (P: = 0.010), ciliary flush (P: = 0.022), photophobia (P: = 0.027), and pain (P: = 0.043). Five times as many patients were dropped from the study for lack of efficacy from the vehicle group (22/52) than from the ketorolac group (4/52; P: = 0.001). Ketorolac was found to be equally as safe as vehicle in terms of adverse events, changes in visual acuity, intraocular pressure, and biomicroscopic and ophthalmoscopic variables. Ketorolac tromethamine 0.5% ophthalmic solution was significantly more effective than vehicle in the treatment of moderate or greater ocular inflammation following routine cataract surgery, while being as safe as vehicle.

The adequate perioperative antibiotic prophylaxis in head and neck cancer surgery is an important and easy applicable tool to decrease nosocomial morbidity and mortality by reducing the rate of infections. In the study a strictly perioperative antibiosis is compared with an extended postoperative prophylactic antibiosis. We aim to clarify the value of postoperative prophylactic antibiosis for the recovery and clinical course of patients. In this prospective study 75 consecutive patients, who underwent major oncological head and neck surgery were included and divided in three groups, each containing 25 patients. The first group received peri- and postoperative antibiotic prophylaxis (POAP) from the day of operation until the fifth day postoperatively. The second group was treated with perioperative antibiotic prophylaxis (PEAP) only. The third group received perioperative antibiotic prophylaxis and increased local antiseptic care (PAPAC). General anamnestic data was collected, as well as duration of hospitalisation, stay on intensive care unit, rate and type of infections, surgical closure of the tracheostomy, and postoperative blood parameters. There were no statistically significant differences in general diseases or extent of surgery between the groups. There were statistically significant fewer patients suffering from surgical site infections in subjects with POAP (n = 1) in comparison to PEAP (n = 9; p = 0.011) and PAPAC (n = 9; p = 0.011). In contrast, other nosocomial infections (pneumonia, urinary tract infection, sepsis) did not decrease under a prolonged antibiotic prophylaxis. Based on findings of the study, we recommend an extended postoperative antibiotic prophylaxis for patients undergoing major oncological head and neck surgery.

Adhesion is a major complication of endoscopic sinus surgery that may lead to recurrence of chronic rhinosinusitis, necessitating revision surgery. The purpose of this study was to evaluate the effect of hyaluronic acid and hydroxyethyl starch (HA-HES) relative to hyaluronic acid and carboxymethylcellulose (HA-CMC) with regard to anti-adhesion effect. In this multi-center, prospective, single-blind, randomized controlled study, 77 consecutive patients who underwent bilateral endoscopic sinus surgery were enrolled between March 2014 and March 2015. HA-HES and HA-CMC were applied to randomly assigned ethmoidectomized cavities after the removal of middle meatal packing. At the 1st, 2nd and 4th weeks after surgery, the presence and grades of adhesion, edema, and infection were, respectively, examined via endoscopy by a blinded assessor. The incidence and grades of adhesion at the 2-week follow-up were significantly less in the HA-CMC group than in the HA-HES group (p < 0.05). However, with the exception of week 2, there were no significant differences in the incidence or grades of adhesion, edema, and infection between the two groups. When the primary endpoint-the presence of adhesion at the 4-week follow-up-was compared between two groups, the incidence of adhesion in HA-HES group at the 4-week follow-up was 32% and in HA-CMC was 41.3%, indicating that HA-HES was not inferior to HA-CMC in terms of anti-adhesive effect. No severe adverse reactions were noted during the study period. In conclusion, HA-HES is a safe substitutional anti-adhesion agent that has equivalent effect as HA-CMC after endoscopic sinus surgery.

Opioids are commonly used as an epidural adjuvant to local anesthetics, but are associated with potentially serious side effects, such as respiratory depression. The aim of this study was to compare the efficacy and safety of dexmedetomidine with that of fentanyl as an adjuvant to epidural ropivacaine in pediatric orthopedic surgery. This study enrolled 60 children (3-12 years old) scheduled for orthopedic surgery of the lower extremities and lumbar epidural patient-controlled analgesia (PCA). Children received either dexmedetomidine (1 μg/kg) or fentanyl (1 μg/kg) along with 0.2% ropivacaine (0.2 mL/kg) via an epidural catheter at 30 minutes before the end of surgery. Postoperatively, the children were observed for ropivacaine consumption via epidural PCA, postoperative pain intensity, need for rescue analgesics, emergence agitation, and other adverse effects. The mean dose of bolus epidural ropivacaine was significantly lower within the first 6 h after surgery in the dexmedetomidine group, compared with the fentanyl group (0.029±0.030 mg/kg/h vs. 0.053±0.039 mg/kg/h, p=0.012). The median pain score at postoperative 6 h was also lower in the dexmedetomidine group, compared to the fentanyl group [0 (0-1.0) vs. 1.0 (0-3.0), p=0.039]. However, there was no difference in the need for rescue analgesia throughout the study period between groups. The use of dexmedetomidine as an epidural adjuvant had a significantly greater analgesic and local anesthetic-sparing effect, compared to fentanyl, in the early postoperative period in children undergoing major orthopedic lower extremity surgery. © Copyright: Yonsei University College of Medicine 2017

A healthy gingival condition after endodontic surgery may depend on adequate soft tissue management. The aim of this study was to compare 2 incision techniques, papilla base incision (PBI) and intrasulcular flap (IS), which are currently used in endodontic surgery. In the present nonrandomized controlled clinical trial, patients requiring endodontic surgery on a single tooth were enrolled. PBI was used in 1 group and IS was used in the other group. The primary outcomes were changes in periodontal probing depth, gingival recession, and height of the interproximal mesial and distal papillae. Outcome variables were assessed preoperatively and 6 months after surgery. Between-group differences were evaluated through appropriate statistical analysis, with significance set at a P value equal to .05. Each group was composed of 12 patients and the 2 groups were comparable at baseline. Two weeks after surgery, papilla height decreased significantly in the IS group (2.05 and 1.80 mm at the mesial and distal aspects, respectively), whereas no significant decrease in papilla height was observed in the PBI group (0.10 and 0.20 mm). No statistically significant difference between groups was observed after 6 months. No significant difference between groups was found for gingival recession or probing depth at any follow-up time. Better soft tissue preservation in the early postoperative period was achieved using the PBI approach compared with the IS approach. The PBI can be recommended for endodontic surgical procedures involving esthetic regions. Copyright © 2014 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.

This study was designed to investigate whether stepwise tapering of remifentanil at the end of surgery could decrease postoperative pain scores and requirements of rescue analgesics after remifentanil-desflurane anesthesia in patients with thyroidectomy. Sixty two patients undergoing thyroidectomy under general anesthesia were randomly allocated into two groups. All patients were anesthetised with desflurane and high-dose remifentanil. Remifentnail was infused at the rate of 0.3 μg/kg/min until the end of surgery in patients of the control group (group A) whereas remifentanil was tapered gradually from 0.3 to 0.1 μg/kg/min until the end of surgery for at least 30 minutes in patients with group B. Pain scores (0-100 numerical rating scale, NRS), rescue analgesic requirements and adverse events were assessed at 30 min, 2 h, 6 h, 12 h, and 24 h after operation. There was a significant decrease in pain scores at 30 min (20 [0-80] vs. 50 [0-100], P = 0.002) and 2 h (30 [10-60] vs. 40 [20-80], P = 0.018) after surgery in group B compared with group A. In addition, rescue analgesics are less required in group B than in group A postoperatively (2 [1-3] vs. 3 [2,3], P = 0.039). There were no significant differences in adverse events between the two groups. Tapering of remifentanil at the end of surgery decreased postoperative pain scores immediately after thyroidectomy with desflurane and high-dose remifentanil anesthesia.

The purposes of this study were to (i) determine macular hole (MH) closure rates and visual outcomes by comparing two methods of managing traumatic MH (TMH)-an event resulting in severe loss of visual acuity (VA); (ii) characterize patients who undergo spontaneous TMH closure; (iii) determine which TMH patients should be observed before resorting to surgical repair; and (iv) elucidate factors that influence postoperative visual outcomes. Studies (n=10) of patients who were managed by surgery or observation for TMH were meta-analyzed retrospectively. Management modalities included surgical repair (surgery group) and observation for spontaneous hole closure (observation group). In addition, a 12-case series of articles (1990-2014) on spontaneous hole closure was statistically summarized. SAS and Comprehensive Meta-Analysis (CMA) (version 3.0) were used for analysis. For surgery group patients, the fixed-model pooled event rate for hole closure was 0.919 (range, 0.861-0.954) and for observation group patients, 0.368 (range, 0.236-0.448). The random-model pooled event rate for improvement of visual acuity (VA) for surgery group patients was 0.748 (range, 0.610-0.849) and for observation group patients, 0.505 (range, 0.397-0.613). For patients in both groups, the mean age of spontaneous closure was 18.71±10.64 years; mean size of TMHs, 0.18±0.06 decimal degrees (DD); and mean time for hole closure, 3.38±3.08 months. The pooled event rate for visual improvement was 0.748 (0.610-0.849). Hole closure and VA improvement rates of surgery group patients were significantly higher than those for observation group patients. Patients of ≤ 24 years of age with MH sizes of ≤ 0.2DD were more likely to achieve spontaneous hole closure. The interval of time from injury to surgery was statistically significantly associated with the level of visual improvement.

Patients with spinal metastasis from cancer of unknown primary origin have limited life expectancy and poor quality of life. Surgery and radiation therapy remain the main treatment options, but, to our knowledge, there are limited data concerning quality-of-life improvement after surgery and radiation therapy and even fewer data on whether surgical intervention would affect quality of life. Patients were enrolled between January 2009 and January 2014 at the Changzheng Hospital, Shanghai, People's Republic of China. The quality of life of 2 patient groups (one group that underwent surgery followed by postoperative radiation therapy and one group that underwent radiation therapy only) was assessed by the Functional Assessment of Cancer Therapy-General (FACT-G) questionnaire during a 6-month period. A subgroup analysis of quality of life was performed to compare different surgical strategies in the surgical group. A total of 287 patients, including 191 patients in the group that underwent surgery and 96 patients in the group that underwent radiation therapy only, were enrolled in the prospective study; 177 patients completed all 5 checkpoints and 110 patients had died by the final checkpoint. The surgery group had significantly higher adjusted quality-of-life scores than the radiation therapy group in each domain of the FACT-G questionnaire (all p < 0.05). Subgroup analysis showed that adjusted functional and physical well-being scores were higher in the circumferential surgical decompression group. Surgery followed by postoperative radiation therapy improved and maintained quality of life in patients with spinal metastasis from cancer of unknown primary origin in the 6-month assessment. In terms of surgical strategies, circumferential decompression seems better than laminectomy alone in quality-of-life improvement. Therapeutic Level II.

Painful vertebral compression fractures (VCF) caused by osteoporosis are a common health problem in the elderly population. If conservative treatments are unsuccessful, surgical treatments like vertebroplasty or kyphoplasty are recommended. But the use of Polymethylmethacrylat (PMMA) bone cement for augmentation surgery is associated with risks. Evaluation of the effectiveness and safety of a newly developed silicon polymer (VK100) that can be used instead of PMMA bone cement for kyphoplasty treatments. A retrospective study of 30 patients comparing the outcomes of kyphoplasty treatments conducted with PMMA and VK100. Clinic for Orthopedics and Trauma Surgery Bonn, Germany. Thirty patients with one to 3 VCF were treated either with balloon kyphoplasty using VK100 or balloon kyphoplasty using PMMA bone cement. Data from both groups was compared by a matched pair analysis. The medial vertebral height was measured at each examination radiologically. The patients stated their pain intensity using the Visual Analogue Scale (VAS) and the patient's functional impairment was evaluated with the Oswestry-Disability-Index (ODI).All data were assessed before surgery, and 3 days, 3 months, 6 months, and 12 months after surgery. Intraoperative and postoperative adverse events were documented. The patients' functional impairment and pain improved significantly after surgery. The course of ODI and VAS was comparable in both treatment groups, but the improvement in the VK group was significantly ongoing until the 12 month follow-up. Vertebral height improvement was significant in both groups, but the PMMA group achieved a better absolute restoration. The vertebral height stayed constant during the follow-up in the VK group and worsened significantly in the PMMA group. There was no significant difference between groups concerning the occurrence of additional fractures; and no other types of complications or surgery-related adverse events were observed in either the PMMA group or in the VK group. The study is only a matched pair analysis of 15 patients for each procedure and the amount of injected filling material was not recorded. The study results demonstrate that the clinical outcome of VAS and ODI of using the silicon polymer VK100 is comparable or slightly better than using PMMA. VK 100 shows a trend to minor additional fractures during the follow-up. However, height restoration is not satisfactory in comparison to PMMA, although vertebral height stayed more or less constant in the VK group. To address the augmentation success further, it would be necessary to study a larger patient group over a longer study period and to assess additional parameters such as bone density and injected amount of filling material.

Urological and sexual dysfunction are recognised risks of rectal cancer surgery; however, there is limited evidence regarding urogenital function comparing robotic to laparoscopic techniques. The aim of this study was to assess the urogenital functional outcomes of patients undergoing laparoscopic and robotic rectal cancer surgery. Urological and sexual functions were assessed using gender-specific validated standardised questionnaires. Questionnaires were sent a minimum of 6 months after surgery, and patients were asked to report their urogenital function pre- and post-operatively, allowing changes in urogenital function to be identified. Questionnaires were sent to 158 patients (89 laparoscopy, 69 robotic) of whom 126 (80 %) responded. Seventy-eight (49 male, 29 female) of the responders underwent laparoscopic and 48 (35 male, 13 female) robotic surgery. Male patients in the robotic group deteriorated less across all components of sexual function and in five components of urological function. Composite male urological and sexual function score changes from baseline were better in the robotic cohort (p < 0.001). In females, there was no difference between the two groups in any of the components of urological or sexual function. However, composite female urological function score change from baseline was better in the robotic group (p = 0.003). Robotic rectal cancer surgery might offer better post-operative urological and sexual outcomes compared to laparoscopic surgery in male patients and better urological outcomes in females. Larger scale, prospective randomised control studies including urodynamic assessment of urogenital function are required to validate these results.

Purpose To assess the impact of cryotherapy or topical minocycline on patients’ perceptions of recovery from pain after third molar surgery in an exploratory comparative-effectiveness study. Patients and Methods Subjects aged at least 14 years who were having all 4 third molars removed were enrolled in 3 separate institutional review board–approved studies. Study groups included subjects treated with a passively applied cold wrap for 24 hours postoperatively, subjects treated with topical minocycline during surgery, and subjects enrolled in a nonconcurrent comparison group who had received neither topical minocycline nor directed cryotherapy. Third molar surgery was performed in all cases by trained surgeons using the same protocol. An exact Kruskal-Wallis test was used to compare the distributions of the worst and average pain scores and a Fisher exact test to compare verbal responses from Gracely pain scales among the 3 groups for postsurgical days (PSDs) 1 to 3. Results This study comprised 51 cryotherapy subjects (2005–2009), 63 minocycline subjects (2003–2004), and 92 comparison-group subjects (2002–2006) who were treated at academic centers and in community practices across the United States (N = 206). Demographic descriptors were similar among all groups. For PSDs 1 through 3 (unadjusted), the highest scores for worst pain (6–7 [out of 7] on Likert-type scale) were reported less frequently in each of the study groups than in subjects in the comparison group, although the numbers of subjects reporting the highest scores were few. The distribution of pain outcomes was significantly different among the 3 groups for worst pain and affective words on PSD 1 (P = .04 for both). However, the small number of subjects who reported the highest pain scores precluded adequate multivariate statistical analyses for all outcomes on PSD 1 to 3. Conclusions Data from this exploratory study suggest that adjunctive therapy to decrease postoperative pain—cryotherapy or topical minocycline—might be effective at moderating the patient’s highest pain levels after third molar surgery. The topic should be studied further in a multicenter, prospective, randomized trial. PMID:21802812

Postoperative bleeding is common complication, affecting up to 20% of patients, after cardiac bypass surgery. Fibrinolysis is one of the causes of this excessive bleeding, and for this reason the use of tranexamic acid is recommended. The problem with using this is that there are numerous guidelines and differences in the dose to be administered. Our aim was to evaluate whether there were any differences in postoperative bleeding and morbidity after cardiac surgery with the administering of different tranexamic acid doses in three university hospitals. A retrospective, multicentre cohort study was conducted. A total of 146 patients who were subjected to elective cardiac bypass surgery according to the anaesthetic-surgical protocol of each hospital were included in the study. The clinical histories were reviewed, and they were divided into two groups according to the tranexamic acid dose: Group A (high doses), initial dose of 20mg/kg and continuous infusion of 4 mg/kg/hour until closure of the sternotomy. A further 100mg was added to prime the bypass machine. Group B (low doses), initial dose of 10mg/kg followed by a continuous infusion of 2mg/kg/hour until closure of the sternotomy. A further 50mg was added to prime the bypass machine. Variables, such as age, sex, weight, height, type of surgical procedure (valvular, coronary or mixed), haematocrit, INR, and preoperative platelet count, time and temperature of the bypass machine, and haematocrit on sternum closure, were recorded. Among the post-operative variables collected were: debit due to drainage at 6, 12 and 24 hours after surgery, number and type of blood products transfused in the first 24 hours, need for further surgery due to haemorrhage, CVA, TIA, or a new acute myocardial infarction, convulsions, and mortality. The incidence of increased bleeding (patients in the 90 percentile) was higher in Group B at all the study evaluation times (P<.05). The incidence of further surgery due to bleeding, and the need for transfusion of ≥ 3 units of packed red cells was lower in Group A (5.56%) than in Group B (13.89%). There were no significant differences in the requirements for blood products transfusions between the groups. As regards associated morbidity, there was one isolated case of convulsion and a perioperative AMI in another case in Group A, and three cases of perioperative AMI in Group B. Elevated doses of tranexamic acid in cardiac bypass surgery appear to significantly reduce bleeding in the first hours after surgery compared to low doses. However, this decrease did not lead to a reduction in the needs for blood products. Copyright © 2012 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.

A meta-analysis regarding bone loss after bariatric surgery, designed to compare surgical and nonsurgical groups, has not yet been performed. Therefore, we performed a meta-analysis to compare the differences between bariatric surgical groups and nonoperated controls with regard to bone mineral density. In March 2015, we performed a review of the literature using PubMed, EMBASE, and the Cochrane Library. The search focused on retrospective and prospective studies, including but not limited to randomized studies published in English. Among 1299 studies that were initially screened, ten met the selection criteria. For all types of bariatric surgery, bone density at the femoral neck was lower in the surgical group than in the nonsurgical control group (mean difference [MD] -0.05 g/cm(2); 95 % confidence interval [CI], -0.07 to -0.02; p = 0.001); no difference in bone density was found between the two groups at the lumbar spine (MD -0.01 g/cm(2); 95 % CI -0.07 to 0.05; p = 0.661). The analysis of Roux-en-Y gastric bypass showed similar results. Bone density at the femoral neck decreased after bariatric surgery, compared to that in nonsurgical controls, whereas bone density at the lumbar spine did not show a difference between groups. Further larger scale studies with comparative nonsurgical controls are warranted to overcome the heterogeneity among studies in this analysis and to add evidence of possible bone loss subsequent to bariatric surgical procedures.

Dexmedetomidine (DEX) is an alpha 2-adrenoreceptor agonist, which induces sedation and analgesia. This study aimed to determine whether intranasal DEX offered perioperative sedation and better postoperative analgesia. Patients having unilateral third molar surgery under local anaesthesia were recruited and allocated to receive either intranasal DEX 1 µg kg(-1) (Group D) or same volume of saline (Group P) 45 min before surgery. Patient-controlled sedation with propofol was offered as a rescue sedative. Perioperative sedation, postoperative pain relief and analgesic consumption, vital signs, adverse events, postoperative recovery, and satisfaction in sedation and analgesia were assessed. Thirty patients from each group were studied. Areas under curve (AUC) of postoperative numerical rating scale (NRS) pain scores 1-12 h at rest and during mouth opening were significantly lower in Group D (P=0.003 and 0.009, respectively). AUC BIS values and OAA/S sedation scores were significantly lower before surgery and at the recovery area (all P<0.01) with significantly less intra-operative propofol used in group D (P<0.01). In group D, heart rate was significantly lower at recovery period (P=0.005) while systolic blood pressure in different periods of the study (all P<0.01), but the decreases did not require treatment. More patients from placebo group experienced dizziness (P=0.026) but no serious adverse event was found. No difference was found in postoperative psychomotor recovery and satisfaction in pain relief and sedation. Patients receiving intranasal DEX for unilateral third molar surgery with local anaesthesia were more sedated perioperatively with better postoperative pain relief. No delay in psychomotor recovery was seen.

It is unclear whether prior endovascular therapy (EVT) adversely affects bypass surgery. The aim of this study is to investigate treatment outcomes between initial bypass (bypass-first) and bypass surgery after EVT (EVT-first). We conducted a retrospective analysis of critical limb ischemia patients undergoing infrapopliteal bypass between November 2006 and December 2015. Graft patency, limb salvage (LS), amputation-free survival (AFS), and overall survival (OS) were examined between bypass-first and EVT-first groups. The subjects in this study were 75 patients and 82 limbs in the bypass-first group and 24 patients and 24 limbs in the EVT-first group. The average age was higher in EVT-first group (P = 0.03). The percentage of inframalleolar bypass was higher in the EVT-first group (P = 0.002). Primary patency at 1 and 2 years was 72.0% and 67.5% for the bypass-first group and 53.1% and 47.2% for the EVT-first group, respectively (P = 0.04). Inframalleolar bypass was a risk factor for lower primary patency (hazard ratio 3.07, 95% confidence interval 1.18-8.51, P = 0.02) in multivariate analysis, while there were no differences in secondary patency, LS, AFS, and OS. Bypass surgery after EVT has lower primary patency rates in comparison with primary bypass in patients submitted to infrapopliteal revascularization. Although very heterogeneous study population with a lot of bias in the indication of the revascularization, LS, OS and AFS are not affected by previous EVT. Copyright © 2017 Elsevier Inc.

The rs9939609 single nucleotide polymorphism (SNP) in the fat mass and obesity-associated (FTO) gene is involved in obesity. Few studies have been conducted on patients who underwent bariatric surgery. The aim of this study was to evaluate the influence of FTO SNPs on body weight, body composition, and weight regain during a 60-mo follow-up period after bariatric surgery. The rs9939609 was genotyped in 146 individuals using a real-time polymerase chain reaction TaqMan assay. Data for lifestyle, comorbidities, body weight, body mass index (BMI), excess weight loss (EWL), and body composition were obtained before and 6, 12, 18, 24, 36, 48, and 60 mo after surgery. Data were analyzed by comparing two groups of patients according to rs9939609 FTO gene polymorphism. Mixed-regression models were constructed to evaluate the dynamics of body weight, BMI, and EWL over time in female patients. No differences were observed between the groups during the first 24 mo after surgery. After 36, 48, and 60 mo, body weight, fat mass, and BMI were higher, whereas fat-free mass and EWL were lower in the FTO-SNP patient group. Weight regain was more frequent and occurred sooner in the FTO-SNP group. There is a different evolution of weight loss in obese carriers of the FTO gene variant rs9939609 after bariatric surgery. However, this pattern was evident at only 2 y postbariatric surgery, inducing a lower proportion of surgery success and a greater and earlier weight regain. Copyright © 2015 Elsevier Inc.

Reduction of cognitive function is a possible side effect after the use of cardiopulmonary bypass (CPB) during cardiac surgery. Since it has been proven that piracetam is cerebroprotective in patients undergoing coronary bypass surgery, we investigated the effects of piracetam on the cognitive performance of patients undergoing open heart surgery. Patients scheduled for elective open heart surgery were randomized to the piracetam or placebo group in a double-blind study. Patients received 12 g of piracetam or placebo at the beginning of the operation. Six neuropsychological subtests from the Syndrom Kurz Test and the Alzheimer's Disease Assessment Scale were performed preoperatively and on day 3, postoperatively. To assess the overall cognitive function and the degree of cognitive decline across all tests after the surgery, we combined the six test-scores by principal component analysis. A total of 88 patients with a mean age of 67 years were enrolled into the study. The mean duration of CPB was 110 minutes. Preoperative clinical parameters and overall cognitive functions were not significantly different between the groups. The postoperative combined score of the neuropsychological tests showed deterioration of cognitive function in both groups (piracetam: preoperative 0.19 ± 0.97 vs. postoperative -0.97 ± 1.38, p <0.0005 and placebo: preoperative -0.14 ± 0.98 vs. postoperative -1.35 ± 1.23, p <0.0005). Patients taking piracetam did not perform better than those taking placebo, and both groups had the same decline of overall cognitive function (p = 0.955). Piracetam had no cerebroprotective effect in patients undergoing open heart surgery. Unlike the patients who underwent coronary surgery, piracetam did not reduce the early postoperative decline of neuropsychological abilities in heart valve patients.

The laparoscopic approach in colorectal complications is controversial because of its difficulty. However, it has been proven that it can provide advantages over open surgery. The aim of this study is to compare laparoscopic approach in reoperations for complications after colorectal surgery with the open approach taking into account the severity of the patient prior to reoperation. Patients who underwent laparoscopic colorectal surgery from January 2006 to December 2015 were retrospectively reviewed. Patients requiring urgent surgical procedures for complications in the postoperative period were divided in two groups: laparoscopic surgery (LS) and open surgery (OS). To control clinical severity prior to reoperation, The Mannheim Peritonitis Index (MPI) was calculated. A total of 763 patients were studied, 40 required urgent surgery (24 OS/16 LS). More ileostomies were performed in the LS group (68.7% vs. 29.2%) and more colostomies in the OS group (37.5% vs. 6.2%), p<0.05. MPI was higher in OS group (27.31±6.47 [19-35] vs. 18.36±7.16 [11-24], p<0.001). Hospital stay after re-intervention, oral tolerance and surgical wound infection, were favorable in LS (p<0.05 in all cases). In patients with MPI score ≤26, laparoscopic approach showed shorter hospital stay after re-intervention, less stay in the critical care unit after re-intervention, earlier start of oral tolerance and less surgical wound infection (p<0.05). A laparoscopic approach in re-intervention for complications after laparoscopic colorectal surgery associates a faster recovery reflected in a shorter hospital stay, earlier start of oral tolerance and a lower abdominal wall complication rate in patients with low severity index.

While there is evidence that physiological data correlate poorly with quality-of-life data or patient-perceived symptom severity, most outcome studies of antireflux surgery still refer physiologic criteria. The aim of this prospective study was to establish whether concomitant aerophagia in GERD (gastroesophageal reflux disease) patients might influence the surgical outcome of laparoscopic 'floppy' Nissen fundoplication. A total of 112 patients were divided into 2 subgroups: group 1 comprising GERD patients without aerophagia (n = 94; 84%); group 2 of GERD patients with concomitant aerophagia (n = 28; 16%). In all patients, requirements for surgery included an evaluation of symptoms (list of 17 symptoms; patients' grading from no--mild to moderate--severe), quality of life (Gastrointestinal Quality of Life Index: GIQLI), esophagogastroduodenoscopy, esophageal manometry and 24-h pH monitoring. Additionally, we asked for any potential stress relations to GERD symptoms. Surgical outcome was assessed 3 months and 1 year postoperatively. In group 2 patients before surgery, we found a significantly higher percentage with a mild impairment of esophageal motility, with a subjectively and objectively dominant reflux in the upright position, with a lower grading of esophagitis or Barrett esophagus, and with a stronger belief that stress was in any relation to perceived symptoms compared with group 1 patients. Additionally, these patients perceived typical and untypical symptoms more intensively. Factors such as DeMeester score and lower esophageal sphincter pressure did not differ preoperatively, the same as after antireflux surgery. Both groups profit significantly from surgery-a continuous reduction of symptom severity and quality-of-life improvement was found. Group 1 patients showed an improvement in mean GIQLI from 93.4+/-8.3 points preoperatively to 123.1+/-7.3 and 122.9+/-9.0 points 3 months and 1 year postoperatively, whereas group 2 patients demonstrated a lower outcome, from 82.2+/-9.1 points to 112.4+/-8.1 and 116.8+/-7.9 points postoperatively. This lesser improvement is the result of preoperative symptoms such as belching, bloating or flatulence, which many patients had after surgery. In addition, some of the group 2 patients suffered from subjective mild to moderate heartburn or dysphagia, but without any objective correlation. GERD patients with concomitant aerophagia demonstrated less symptomatic relief than patients without aerophagia. Moreover, patients with aerophagia showed less quality-of-life improvement after laparoscopic antireflux surgery. There were no significant differences in physiological outcome data between groups. Surgery in GERD patients with symptoms relating to aerophagia should be approached with great care. An additional psychological intervention in these patients might improve surgical outcome.

Gynecologic laparoscopic surgery is frequently accompanied by early postoperative pain. This study assessed the effect of combined general and spinal anesthesia on postoperative pain score, analgesic use, and patient satisfaction following robotic surgeries. This was a randomized controlled trial. Thirty-eight consecutive women who underwent robotic surgeries for pelvic organ prolapse (sacrocolpopexy with or without subtotal hysterectomy) were randomly assigned to receive general anesthesia (control group, n = 20) or combined general with spinal anesthesia (study group, n = 18). Pain scores were assessed at rest and while coughing using a visual analog scale (VAS) 0-10. Dosage of analgesic medication consumption was retrieved from patients' charts. There were no statistically significant differences between the two groups with respect to demographic data and intraoperative hemodynamic parameters. In the postanesthesia care unit (PACU) mean total IV morphine and meperidine dosages were significantly lower for the study than the control group (0.33 vs 7.59 mg, 1.39 vs 27.89 mg, respectively, P < 0.003, <0.001, respectively). In addition, a significantly lower percentage of patients belonging to the study group demanded analgesic medications while in the PACU (33 vs 53 %, P = 0.042). Pain scores in the PACU and during postoperative day 1 were significantly lower in the study group than in the control group (delta VAS 1.9 vs 3.0, P = 0.04). Satisfaction with pain treatment among both patients and nurses was significantly higher in the study group. Reported levels of pain and analgesic use during the first 24 h following robotic gynecologic surgery were significantly lower following general and spinal anesthesia compared to general anesthesia alone.

Does off-pump coronary artery bypass graft surgery have a beneficial effect on long-term mortality and morbidity compared with on-pump coronary artery bypass graft surgery?

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether off-pump coronary artery bypass grafting (CABG) surgery offered superior long-term outcomes compared with on-pump CABG surgery. Best evidence papers were considered to be those that had a follow-up period of ≥5 years, had >50 patients in either cohort, did not utilize concomitant interventions nor comprised low-risk, high-risk or sub-population groups. Where potential duplicate data sets from the same institution were likely, the more credible and recently published study was included. Two hundred and fifty-six papers were found as a result of the reported search, of which 16 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. The 16 studies comprised 4 prospective randomized controlled trials (RCTs), with the remaining 12 retrospective, of which 8 were propensity-score matched. All 4 RCTs contained fewer than 450 participants. Two studies concluded with a survival advantage towards on-pump CABG: one, a large registry-based study, the Veterans Affairs, with >25 000 patients, and another, a propensity-matched retrospective study involving almost 8000 patients. The remaining 14 studies all provided evidence to suggest comparable long-term survival. In addition, all other long-term outcomes mentioned within these studies including angina recurrence, myocardial infarction heart failure, need for revascularization, stroke, graft patency, cognitive and quality of life showed similar results between the two groups. We conclude that off-pump CABG surgery may have similar or slightly reduced long-term survival compared with on-pump CABG surgery. Other long-term indicators such as cardiovascular or cerebrovascular events or neuro-psychological outcomes were similar between the two groups. Despite these conclusions, the evidence is limited by substantial variability in patient selection and study methods. The CORONARY (coronary artery bypass surgery off- or on-pump revascularization study) trial recently presented results, which showed no significant differences in composite outcomes at 1 year; it will be interesting to observe whether these comparable outcomes are maintained for a much longer time frame. © The Author 2014.

To investigate the effects of preemptive analgesia with parecoxib sodium on haemodynamics and plasma stress hormones in surgical patients with thyroid carcinoma. Fifty-seven patients with thyroid carcinoma who underwent thyroidectomy selectively in Laiwu Hospital Affiliated to Taishan Medical University and Binzhou People's Hospital were selected and randomly divided into three groups, 19 cases in each group. The control group was intravenously injected 0.9% sodium chloride injection before anesthesia induction; trial group I was intravenously injected with parecoxib sodium 20 min before anesthesia induction; based on trial group I, trial group II was injected with parecoxib sodium again 12 h after surgery. The levels of plasma norepinephrine (NE), cortisol (Cor) and blood glucose before, 12 and 24 h after surgery and changes of haemodynamics before surgery, at the end of surgery and 12, 24 and 48 h after surgery were compared in the three groups. Besides, visual analogue scale (VAS) scores were recorded 4, 8, 12 and 24 h after surgery. 12 and 24 h after surgery, the levels of plasma NE and Cor in three groups rose dramatically (P<0.05 or (P<0.01); The levels of plasma NE and Cor in trial groups I and II were evidently lower than in control group (P<0.05 or P<0.01), and those in trial group II slightly lower than in trial group I. 12 h after surgery, the heart rates (HR) and systolic pressures (SBP) in trial groups I and II increased obviously by comparison to surgery before (P<0.05 or P<0.01), but gradually returned to the preoperative level. HR, SBP and diastolic pressures (DBP) in trial groups I and II at the end of surgery and 12 h after surgery were all lower than in the control group, and significant differences were present (P<0.05 or (P<0.01). At 4, 8, 12 and 24 h after surgery, VAS scores in trial groups I and II were markedly lower than in the control group ((P<0.05 or (P<0.01), the scores in trial group II being the lowest. Combined application of parecoxib sodium for preemptive analgesia before anesthesia and after surgery can effectively reduce the levels of plasma stress hormones and improve analgesic effects in surgical patients with thyroid carcinoma, and without conspicuous impact on haemodynamics.

Tibialis anterior tendon transfer surgery forms a part of Ponseti management for children with congenital talipes equinovarus who, after initial correction, present with residual dynamic supination. Although retrospective studies support good outcomes, prospective longitudinal studies in this population are lacking. We assessed strength, plantar loading, ROM, foot alignment, function, satisfaction, and quality of life in patients with clubfoot that recurred after Ponseti casting who met indications for tibialis anterior tendon transfer surgery, and compared them with a group of patients with clubfoot treated with casting but whose deformity did not recur (therefore who were not indicated for tibialis anterior tendon transfer surgery). Twenty children with idiopathic congenital talipes equinovarus indicated for tibialis anterior tendon transfer surgery were recruited. Assessment at baseline (before surgery), and 3, 6, and 12 months (after surgery) included strength (hand-held dynamometry), plantar loading (capacitance transducer matrix platform), ROM (Dimeglio scale), foot alignment (Foot Posture Index(©)), function and satisfaction (disease-specific instrument for clubfoot), and quality of life (Infant Toddler Quality of Life Questionnaire™). Outcomes were compared with those of 12 age-matched children with congenital talipes equinovarus not indicated for tibialis anterior tendon transfer surgery. Followup was 100% in the control group and 95% (19 of 20) in the tibialis anterior transfer group. At baseline, the tibialis anterior tendon transfer group had a significantly worse eversion-to-inversion strength ratio, plantar loading, ROM, foot alignment, and function and satisfaction. At 3 months after surgery, eversion-to-inversion strength, plantar loading, and function and satisfaction were no longer different between groups. Improvements were maintained at 12 months after surgery (eversion-to-inversion strength mean difference, 8% body weight; 95% CI, -26% to 11%; p = 0.412; plantar loading, p > 0.251; function and satisfaction, p = 0.076). ROM remained less and foot alignment more supinated in the tibialis anterior tendon transfer group between baseline and followup (p < 0.001, p < 0.001). Tibialis anterior tendon transfer surgery was an effective procedure, which at 12-month followup restored the balance of eversion-to-inversion strength and resulted in plantar loading and function and satisfaction outcomes similar to those of age-matched children with congenital talipes equinovarus who after Ponseti casting were not indicated for tibialis anterior tendon transfer.

This study aimed to compare the outcomes of stereotactic body radiotherapy (SBRT) and surgery in elderly patients with cT1-2N0M0 non-small cell lung cancer (NSCLC). Elderly patients (≥75 years) with cT1-2 (≤5 cm) N0M0 NSCLC who were treated with SBRT (n=35) or surgery (n=183) between January 2001 and December 2011 were analyzed. The following radiation doses were administered: 48 Gy/4-6 fractions in 12 patients; 50 Gy/4-5 fractions in 20; and 60 Gy/8 fractions in 3. The following surgical methods were performed: pneumonectomy in 2 patients, lobectomy in 154, segmentectomy in 23, and wedge resection in 4. Patients in the SBRT group had a higher mean age, a worse performance status, and a lower percentage of forced expiratory volume in 1.0 s than those in the surgery group. The overall 5-year survival rates were 43.8% and 67.6% for the SBRT and surgery groups, respectively (p=0.057, log-rank test). Regarding tumor diameter, patients in the surgery group survived significantly longer than did those in the SBRT group (>20-mm tumors, p=0.027; >30-mm tumors p=0.043), whereas survival did not differ significantly between the groups for ≤20-mm tumors (p=0.982). Multivariate analysis confirmed the improved survival in the surgery group compared to the SBRT group for all tumors (p=0.034) and for >20-mm tumors (p=0.016). Post-therapeutic survival among elderly patients might be better with surgery than with SBRT in NSCLC patients with tumors >20 mm. Copyright © 2014 The Japanese Respiratory Society.

Umbilical hernias are well described in the literature, but its impact on health care is less understood. The purpose of this study was to investigate the effect of non-operative management of umbilical hernias on cost, work absenteeism, and resource utilization. The Truven Health Database, consisting of 279 employers and over 3000 hospitals, was reviewed for all umbilical hernia patients, aged 18-64 who were enrolled in health plans for 12 months prior to surgery and 12 months after surgery. Patients were excluded if they had a recurrence or had been offered a "no surgery" approach within 1 year of the index date. The remaining patients were separated into surgery (open or laparoscopic repair) or no surgery (NS). Post-cost analysis at 90 and 365 days and estimated days off from work were reviewed for each group. The non-surgery cohort had a higher proportion of females and comorbidity index. Adjusted analysis showed significantly higher 90 and 365 costs for the surgery group (p < 0.0001), though the cost difference did decrease over time. NS group had significantly higher estimated days of health-care utilization at both the 90 (1.99 vs. 3.58 p < 0.0001) and 365 (8.69 vs. 11.04 p < 0.0001) day post-index mark. A subgroup analysis demonstrated laparoscopic repair had higher costs compared to open primarily due to higher index procedure costs (p < 0.05). Though the financial costs were found to be higher in the surgery group, the majority of these were due to the surgery itself. Significantly higher days of health-care utilization and estimated days off work were experienced in the NS group. It is our belief that early operative intervention will lead to decreased costs and resource utilization.

The effect of mannitol on intraoperative brain relaxation in patients undergoing supratentorial tumor surgery: study protocol for a randomized controlled trial

PubMed Central

2014-01-01

Background The risk of brain swelling after dural opening is high in patients with midline shift undergoing supratentorial tumor surgery. Brain swelling may result in increased intracranial pressure, impeded tumor exposure, and adverse outcomes. Mannitol is recommended as a first-line dehydration treatment to reduce brain edema and enable brain relaxation during neurosurgery. Research has indicated that mannitol enhanced brain relaxation in patients undergoing supratentorial tumor surgery; however, these results need further confirmation, and the optimal mannitol dose has not yet been established. We propose to examine whether different doses of 20% mannitol improve brain relaxation in a dose-dependent manner when administered at the time of incision. We will examine patients with preexisting mass effects and midline shift undergoing elective supratentorial brain tumor surgery. Methods This is a single-center, randomized controlled, parallel group trial that will be carried out at Beijing Tiantan Hospital, Capital Medical University. Randomization will be achieved using a computer-generated table. The study will include 220 patients undergoing supratentorial tumor surgery whose preoperative computed tomography/magnetic resonance imaging results indicate a brain midline shift. Patients in group A, group B, and group C will receive dehydration treatment at incision with 20% mannitol solutions of 0.7, 1.0, and 1.4 g/kg, respectively, at a rate of 600 mL/h. The patients in the control group will not receive mannitol. The primary outcome is an improvement in intraoperative brain relaxation and dura tension after dehydration with mannitol. Secondary outcomes are postoperative outcomes and the incidence of mannitol side effects. Discussion The aim of this study is to determine the optimal dose of 20% mannitol for intraoperative infusion. We will examine brain relaxation and outcome in patients undergoing supratentorial tumor surgery. If our results are positive, the study will indicate the optimal dose of mannitol to improve brain relaxation and avoid side effects during brain tumor surgery.

The purpose of this study was to compare the level of patient pain during the phacoemulsification and implantation of foldable intraocular lenses while under topical, intracameral, or sub-Tenon lidocaine. This was a retrospective study. Three hundred and one eyes subjected to cataract surgery were included in this study. All eyes underwent phacoemulsification surgery and intraocular lens implantation using topical, sub-Tenon, or intracameral anesthesia. The topical group received 4% lidocaine drops, and the intracameral group received a 0.1-0.2 cc infusion of 1% preservative-free lidocaine into the anterior chamber through the side port combined with topical drops of lidocaine. The sub-Tenon group received 2% lidocaine. Best-corrected visual acuity, corneal endothelial cell loss, and intraoperative pain level were evaluated. Pain level was assessed on a visual analog scale (range 0-2). There were no significant differences in visual outcome and corneal endothelial cell loss between the three groups. The mean pain score in the sub-Tenon group was significantly lower than that in the topical and intracameral groups (P=0.0009 and P=0.0055, respectively). In 250 eyes without high myopia (< -6D), there were no significant differences in mean pain score between the sub-Tenon and intracameral groups (P=0.1417). No additional anesthesia was required in all groups. Intracameral lidocaine provides sufficient pain suppressive effects in eyes without high myopia, while sub-Tenon anesthesia is better for cataract surgery in eyes with high myopia.

Bariatric surgery is an effective treatment option for both obesity and obesity-related type 2 diabetes mellitus (T2DM). However, little is known regarding the effects of bariatric surgery on erectile dysfunction among patients with T2DM. Therefore, we investigated whether bariatric surgery would lead to structural and biochemical changes in the corpus cavernosum. Twenty-five male Otsuka Long-Evans Tokushima Fatty rats were assigned to either a control group (sham operation, n = 10) or a bariatric surgery group (gastric bypass surgery, n = 15). Four weeks after the operation, each group of rats was evaluated with an oral glucose tolerance test (OGTT). The penile intracavernous pressure was measured for erectile functional analysis. Histologic evaluation of the tissue was performed with Masson's trichrome staining. Endothelial nitric oxide synthase (eNOS), neuronal nitric oxide synthase (nNOS), Rho kinase, and 8-hydroxy-2-deoxyguanosine (8-OHdG) levels in the corpus cavernosum were assayed by using western blot and ELISA. The mean body weight of the bariatric surgery group was lower than the control group (p = 0.002). The postoperative OGTT result was lower in the bariatric surgery group than in the control group (p = 0.014), and this was lower than the preoperative value (p = 0.037). The intracavernous pressure/mean arterial pressure ratio was higher in the bariatric surgery group compared to the control group (p = 0.021), and a higher cavernosum smooth muscle/collagen ratio was observed in the bariatric surgery group compared to the control group (p = 0.025). Likewise, the expression of eNOS and nNOS was higher in bariatric surgery group than in the control group (p = 0.027 and p = 0.008, respectively). Decreased expression of Rho kinase and levels of 8-OHdG were observed in the bariatric surgery group (p = 0.032). In this animal model, bariatric surgery appears to ameliorate T2DM-related metabolic dysfunction leading to structural and biochemical changes in the corpus cavernosum, and thus, results in improvement of erectile dysfunction associated with T2DM.

To assess long-term quality of life in surviving patients with advanced laryngeal cancer. A follow-up long-term quality-of-life survey of patients randomized to the Veterans Affairs Laryngeal Cancer Study No. 268 on induction chemotherapy and radiation (CT + RT) vs surgery and RT. Forty-six (71%) of the 65 surviving patients with prior stage III or IV laryngeal cancer who could be contacted completed the survey: 25 from the surgery and RT group and 21 from the CT + RT group. Baseline demographic and clinical characteristics among survey respondents were similar, except that those in the CT + RT group were significantly older (mean, 61.2 years) than those in the surgery and RT group (mean, 55.7 years; P<.05). Patients completed the University of Michigan Head and Neck Quality of Life (HNQOL) instrument, the Medical Outcomes Studies Short-Form 36 (SF-36) general health survey, the Beck Depression Inventory as well as smoking and alcohol consumption surveys. Patients randomized to the CT + RT group had significantly better (P<.05) quality-of-life scores on the SF-36 mental health domain (76.0) than the surgery and RT group (63.0), and also had better HNQOL pain scores (81.3 vs 64.3). Compared with patients who underwent laryngectomy, patients with intact larynges (CT + RT with larynx) had significantly less bodily pain (88.5 vs 56.5), better scores on the SF-36 mental health (79.8 vs 64.7), and better HNQOL emotion (89.7 vs 79.4) scores. More patients in the surgery and RT group (28%) were depressed than in the CT + RT group (15%). Better quality-of-life scores in the CT + RT groups appear to be related to more freedom from pain, better emotional well-being, and lower levels of depression than to preservation of speech function.

Background Vitamin C has critical features relavant to postoperative pain management and functional improvement; however, no study has yet evaluated the effectiveness of vitamin C on improving the surgical outcomes for spine pathologies. Thus, this study aimed to explore the impact of vitamin C on postoperative outcomes after single-level posterior lumbar interbody fusion (PLIF) for lumbar spinal stenosis in prospectively randomized design. We conducted a 1-year prospective, randomized, placebo-controlled, double-blind study to evaluate the impact of vitamin C on the postoperative outcomes after PLIF surgery. Methods A total of 123 eligible patients were randomly assigned to either group A (62 patients with vitamin C) or group B (61 patients with placebo). Patient follow-up was continued for at least 1 year after surgery. The primary outcome measure was pain intensity in the lower back using a visual analogue scale. The secondary outcome measures were: (1) the clinical outcome assessed using the Oswestry Disability Index (ODI); (2) the fusion rate assessed using dynamic radiographs and computed tomography scans; and (3) complications. Results Pain intensity in the lower back was significantly improved in both groups compared with preoperative pain intensity, but no significant difference was observed between the 2 groups over the follow-up period. The ODI score of group A at the third postoperative month was significantly higher than the score of group B. After the sixth postoperative month, the ODI score of group A was slightly higher than the score of group B; however, this difference was not significant. The fusion rates at 1 year after surgery and the complication rates were not significantly different between the 2 groups. Conclusions Postoperative pain intensity, the primary outcome measure, was not significantly different at 1 year after surgery between the 2 groups. However, vitamin C may be associated with improving functional status after PLIF surgery, especially during the first 3 postoperative months. PMID:28861199

To investigate the applicability of the eysphonia severity index (DSI) in evaluating effects of surgery between before and after groups of vocal polyp patients. Analyses of measurement data pre and pro-surgery of 70 vocal polyp patients and 35 no voice disorders volunteers (control group). The voice quality was measured subjectively with the voice handicap index (VHI), the GRBAS and fiber electronic laryngoscopy. Measures of maximum phonation time (MPT), shimmer and jitter were obtained for each subject by using DiVAS 2.30 (XION, Germany). The DiVAS 2.30 had spotanenously calculate the scores of DSI. Using SPSS 17.0 to find the differences of DSI scores among the three groups by one-way ANOVA variance analysis. And finding out of the correlation with DSI scores and VHI scores, GRBAS, MPT, jitter and shimmer. DSI improved significantly after surgery in the vocal polyps group (mean difference DSI -2.92 and 1.87, respectively) and also in the control group (mean difference DSI -2.92 and 2.30, respectively). However, no significant difference between the control group and the after surgery group. By using Pearson correlation analysis, this study observed a strong correlation between the DSI scores and the VHI scores, the values of GRBAS, shimmer (P < 0.01). DSI is an effective and high accuracy multi-parameter system for evaluation of vocal cord polyp patients as an independent assessment of dysphonia. DSI also can be used in evaluation of the effects of the vocal polyps surgery.

Background The introduction of endourological procedures such as percutaneous nephrolithotomy and ureterorenoscopy have led to a revolution in the the management of urinary stone disease. The indications for open stone surgery have been narrowed significantly, making it a second- or third-line treatment option. Aims and Objectives To study the safety and efficacy of retroperitoneal laparoscopic pyelolithotomy in retroperitoneal renal stone. We compared the results of laparoscopic and open surgery in terms of easy accessibility, operative period, renal injuries, and early recovery. Methods This prospective study was conducted on renal pelvic stone cases from January 2009 to February 2016 in Suchkhand Hospital, Agra, India. The study included a total of 1700 cases with the diagnosis of solitary renal pelvic stones. In group A - 850 cases - retroperitoneal laparoscopic pyelolithotomy was performed, while group B - 850 cases – underwent open pyelolithotomy. Results The mean operative time was less in group B than group A (74.83 min vs. 94.43 min) which was significant (p<0.001). The blood loss was less in the laparoscopic group than in the open group (63 mL vs. 103mL). There were statistically significant differences in the post-operative pain scores, and postoperative complications compared to group B (p<0.001). The mean hospital stay was less in group A (p<0.03), which was significant. Conclusion Laparoscopic surgery reduces analgesic requirements, hospital stay, and blood loss. The disadvantages include the reduced working space, the cost of equipment and the availability of a trained surgeon. PMID:29440956

Insulin therapy is the most commonly used treatment for controlling hyperglycemia after coronary artery bypass surgery in both diabetic and nondiabetic patients. Metformin has been indicated for critically ill patients as an alternate for the treatment of hyperglycemia. This study evaluated the effect of metformin and insulin in hyperglycemia treatment after coronary artery bypass surgery in nondiabetic patients. This study was a clinical trial comprising nondiabetic patients who had undergone coronary artery bypass surgery. Patients were randomly divided into the insulin group and the metformin group. Patients in the insulin group received continuous infusion of insulin while those in the metformin group received 500 mg metformin tablets twice daily. All the patients were followed up for 3 days after stabilization of blood glucose levels. Data were analyzed using Chi-square test and Mann-Whitney U-test. This study included a total of 56 patients. During the study period, the mean blood glucose levels decreased from 225.24 to 112.36 mg/dl (↓112.88 mg/dl) in the insulin group and from 221.80 to 121.92 mg/dl in the metformin group (↓99.88 mg/dl). There was no significant difference in the blood glucose levels of the patients between the two groups at any measurement times (P > 0.05). Using 500 mg metformin twice daily is similar to using insulin in nondiabetic patients undergoing coronary artery bypass graft. Therefore, the use of metformin can be considered as a treatment strategy for controlling hyperglycemia in this group of patients.

Fiscal constraints are driving shorter hospital lengths of stay. Outpatient primary cleft lip surgery has been shown to be safe, but outpatient primary cleft palate surgery remains controversial. This study evaluates outcomes following outpatient versus inpatient primary cleft lip and palate surgery. The American College of Surgeons National Surgical Quality Improvement Program Pediatric database was used to identify patients undergoing primary cleft lip and palate surgery between 2012 and 2015. Patient clinical factors and 30-day complications were compared for outpatient versus inpatient primary cleft lip and palate surgery. Univariate and multivariate analyses were performed. Three thousand one hundred forty-two patients were included in the primary cleft lip surgery group and 4191 in the primary cleft palate surgery group. Patients in the cleft lip surgery group with structural pulmonary abnormalities had a significantly longer hospital length of stay (β, 4.94; p = 0.001). Patients undergoing outpatient surgery had a significantly higher risk of superficial (OR, 1.99; p = 0.01) and deep wound dehiscence (OR, 2.22; p = 0.01), and were at a significantly lower risk of reoperation (OR, 0.36; p = 0.04) and readmission (OR, 0.52; p = 0.02). Outpatient primary cleft lip surgery is safe and has a complication profile similar to that of inpatient surgery. Outpatient primary cleft palate surgery is common practice in many U.S. hospitals and has a significantly higher rate of wound complications, and lower rates of reoperation and readmission. In properly selected patients, outpatient palatoplasty can be performed safely. Therapeutic, III.

Postoperative wound infection also called as surgical site infection (SSI), is a trouble some complication of lumbar spine surgeries and they can be associated with serious morbidities, mortalities and increase resource utilization. With the improvement in diagnostic modalities, proper surgical techniques, antibiotic therapy and postoperative care, infectious complications can result in various compromises afterwards. The objective was to study the relation of surgical site infection in clean lumbar surgeries with the doses of antibiotics. This Retrospective study was conducted at Shifa International Hospital, from January 2006 to March 2008. Hundred post operated cases of lumber disc prolapse, lumbar stenosis or both studied retrospectively by tracing their operated data from hospital record section for the development of surgical site infection (SSI). The patients were divided into three groups depending upon whether they received single, three or more than three doses of antibiotics respectively. Complete data analyses and cross tabulation done with SPSS version 16. Of 100 cases, only 6% had superficial surgical site infection; only 1 case with co morbidity of hypertension was detected. Twenty-one cases had single dose of antibiotic (Group-I), 59 cases had 3 doses (Group-II) and 20 cases received multiple doses (Group-III). There was no infection in Group-I. Only one patient in Group-II and 5 patients in Group-III developed superficial SSI. While 4 in Group-II, 3 in Group-III, and none of Group-I had > 6 days length of stay (LOS). The dose of antibiotic directly correlates with the surgical site infection in clean lumbar surgeries. When compared with multiple doses of antibiotics a single preoperative shot of antibiotic is equally effective for patients with SSI.

Background and Objective Our objective was to report on the design and essentials of the Etoricoxib protocol- Preemptive and Postoperative Analgesia (EPPA) Trial, investigating whether preemptive analgesia with cox-2 inhibitors is more efficacious than placebo in patients who receive either laparotomy or thoracotomy. Design and Methods The study is a 2 × 2 factorial armed, double blinded, bicentric, randomised placebo-controlled trial comparing (a) etoricoxib and (b) placebo in a pre- and postoperative setting. The total observation period is 6 months. According to a power analysis, 120 patients scheduled for abdominal or thoracic surgery will randomly be allocated to either the preemptive or the postoperative treatment group. These two groups are each divided into two arms. Preemptive group patients receive etoricoxib prior to surgery and either etoricoxib again or placebo postoperatively. Postoperative group patients receive placebo prior to surgery and either placebo again or etoricoxib after surgery (2 × 2 factorial study design). The Main Outcome Measure is the cumulative use of morphine within the first 48 hours after surgery (measured by patient controlled analgesia PCA). Secondary outcome parameters include a broad range of tests including sensoric perception and genetic polymorphisms. Discussion The results of this study will provide information on the analgesic effectiveness of etoricoxib in preemptive analgesia and will give hints on possible preventive effects of persistent pain.

Shoulder problems are common in patients with a cervical herniated intervertebral disc (HIVD). This study aimed to explore the incidence and risk of shoulder capsulitis/tendonitis following cervical HIVD surgery. We used data from the Taiwan "Longitudinal Health Insurance Database". We identified all patients who were hospitalized with a diagnosis of displacement of a cervical HIVD and who underwent cervical surgery (n = 1625). We selected 8125 patients who received cervical HIVD conservative therapy only as the comparison group matched with study patients. We individually tracked these sampled patients for 6 months to identify all patients who received a diagnosis of shoulder tendonitis/capsulitis. We found that incidence rates of shoulder tendonitis/capsulitis during the 6-month follow-up period were 3.69 (95% CI: 2.49~5.27) per 100 person-years for the study group and 2.33 (95% CI: 1.89~2.86) per 100 person-years for the comparison group. Cox proportional hazard regressions showed that the adjusted hazard ratio for shoulder tendonitis/capsulitis among patients who underwent cervical disc surgery was 1.66 (95% CI = 1.09~2.53) when compared to comparison group. We concluded that patients who underwent surgery for a cervical HIVD had a significantly higher risk of developing shoulder capsulitis/tendonitis in 6 months follow-up compared to patients who received cervical HIVD conservative therapy only.

Traditional practice after vaginal hysterectomy was to keep the vaginal pack and urinary catheter for 24 hours post operatively. But there were studies that prolonged cathterisation was associated with urinary infection. So this study was conducted to compare the post operative outcome when the urinary catheter and vaginal pack were removed after 3 hours and after 24 hours after surgery. The study was done in the Department of Obstetrics and Gynecology, in a tertiary teaching institute of South India from September 2008 to March 2010. It was a randomised controlled trial involving 200 women undergoing vaginal surgery, who were randomly assigned to 2 groups - catheter and vaginal pack were removed either in 3 h in study group or were removed in 24 h in control group. The outcome of the study were vaginal bleeding, urinary retention, febrile morbidity, and urinary infection. There was no significant difference between the study and control groups with respect to vaginal bleeding (0 and 1%, p = 1), urinary retention (9 and 4%, p = 0.15), febrile morbidity (7 and 4%, p = 0.35), and urinary infection (26% in each group, p = 1.0). Keeping the urinary catheter and vaginal pack for 24 h following vaginal surgery does not offer any additional benefit against removing them after 3 h.

Objective This study compared the stone opacity effect in patients who had radiopaque and radiolucent stones in percutaneous nephrolithotomy (PCNL) results. Material and methods The medical records of 171 complete supine PCNL procedures were gathered. Patients were categorized into two groups: those with radiopaque (n=141) and those with radiolucent (n=30) stones. Kidney, ureter and bladder x-ray was done a day after PCNL and Ultrasound imaging was done two weeks later to evaluate the stone free rate. A stone free result was defined as having less than 4 mm residual stone size. Outcome parameters were compared by univariate analysis and those which were significantly different between the two groups were assessed by multivariate binary logistic regression analysis. Results There were no significant differences in age, sex, body mass index, hypertension, diabetes mellitus, pre-surgery hemoglobin, pre-surgery serum creatinine, stone and also surgery-related parameters between the two groups. Stone free rate, surgery time, complication-related parameters, hemoglobin drop, serum creatinine and glomerular filtration rate (GFR) changes were similar in both groups based on univariate analysis. The radiopaque group had higher post-surgery GFR (p=0.04) and longer hospital stay (p=0.009). However, opacity had no effect on these outcomes after multivariate analysis. Higher post-surgery GFR was seen in patient with higher GFR before surgery (p<0.0001). Also, higher hemoglobin before surgery was correlated with less hospital stay (p=0.001). Conclusion The complete supine percutaneous nephrolithotomy outcomes are similar in patients with radiopaque and radiolucent stones. PMID:29201513

This study compared the stone opacity effect in patients who had radiopaque and radiolucent stones in percutaneous nephrolithotomy (PCNL) results. The medical records of 171 complete supine PCNL procedures were gathered. Patients were categorized into two groups: those with radiopaque (n=141) and those with radiolucent (n=30) stones. Kidney, ureter and bladder x-ray was done a day after PCNL and Ultrasound imaging was done two weeks later to evaluate the stone free rate. A stone free result was defined as having less than 4 mm residual stone size. Outcome parameters were compared by univariate analysis and those which were significantly different between the two groups were assessed by multivariate binary logistic regression analysis.

To investigate the reliability of a biometric iris recognition system for personal authentication after cataract surgery or iatrogenic pupil dilation. This was a prospective, nonrandomized, single-center, cohort study for evaluating the performance of an iris recognition system 2-24 hours after phacoemulsification and intraocular lens implantation (group 1) and before and after iatrogenic pupil dilation (group 2). Of the 173 eyes that could be enrolled before cataract surgery, 164 (94.8%) were easily recognized postoperatively, whereas in 9 (5.2%) this was not possible. However, these 9 eyes could be reenrolled and afterwards recognized successfully. In group 2, of a total of 184 eyes that were enrolled in miosis, a total of 22 (11.9%) could not be recognized in mydriasis and therefore needed reenrollment. No single case of false-positive acceptance occurred in either group. The results of this trial indicate that standard cataract surgery seems not to be a limiting factor for iris recognition in the large majority of cases. Some patients (5.2% in this study) might need "reenrollment" after cataract surgery. Iris recognition was primarily successful in eyes with medically dilated pupils in nearly 9 out of 10 eyes. No single case of false-positive acceptance occurred in either group in this trial. It seems therefore that iris recognition is a valid biometric method in the majority of cases after cataract surgery or after pupil dilation.

The feasibility and radicalism of lymph node dissection for lung cancer surgery by a single-port technique has frequently been challenged. We performed a retrospective cohort study to investigate this issue. Two chest surgeons initiated multiple-port thoracoscopic surgery in a 180-bed cancer centre in 2005 and shifted to a single-port technique gradually after 2010. Data, including demographic and clinical information, from 389 patients receiving multiport thoracoscopic lobectomy or segmentectomy and 149 consecutive patients undergoing either single-port lobectomy or segmentectomy for primary non-small-cell lung cancer were retrieved and entered for statistical analysis by multivariable linear regression models and Box-Cox transformed multivariable analysis. The mean number of total dissected lymph nodes in the lobectomy group was 28.5 ± 11.7 for the single-port group versus 25.2 ± 11.3 for the multiport group; the mean number of total dissected lymph nodes in the segmentectomy group was 19.5 ± 10.8 for the single-port group versus 17.9 ± 10.3 for the multiport group. In linear multivariable and after Box-Cox transformed multivariable analyses, the single-port approach was still associated with a higher total number of dissected lymph nodes. The total number of dissected lymph nodes for primary lung cancer surgery by single-port video-assisted thoracoscopic surgery (VATS) was higher than by multiport VATS in univariable, multivariable linear regression and Box-Cox transformed multivariable analyses. This study confirmed that highly effective lymph node dissection could be achieved through single-port VATS in our setting. © The Author 2015.

The purpose of this study is to evaluate whether a nutritional supplement with a high blend ratio of ω-3 fatty acids can minimize weight loss and attenuate increases in inflammatory marker levels during the perioperative period in patients undergoing surgery for head and neck carcinoma. Patients with ≥5% weight loss within 6 months were considered as targets for aggressive nutritional intervention. Among these patients, those with head and neck squamous cell carcinoma, who underwent major invasive surgery with free flap reconstruction were included in the present study. The patients were randomized into two groups: the 'nutritional supplementation group' and the 'non-intervention group'. The nutritional supplementation group received two packs of Prosure® (an eicosapentaenoic acid [EPA]-enriched oral nutritional supplement) per day for 28 days during the perioperative period. Compliance with the Prosure® dosage was very good at 6277/6720 ml (average) before surgery (93%) and 5229/6720 ml after surgery (78%), and a significant increase in EPA concentration was shown in the group that received Prosure® (P < 0.0001: Welch's t-test). However, 28 days of nutritional supplementation did not lead to further weight change or changes in the inflammatory marker levels of patients were already showing cachexia (based on weight loss). Interestingly, no further change in the mean weight was noted in these patients. The incidence of postoperative complications did not differ between the two groups. In this trial, immunonutritional therapy using a nutritional supplement with a high blend ratio of ω-3 fatty acids from 2 weeks before surgery until 2 weeks after surgery was not effective for maintaining the nutritional status of head and neck carcinoma patients.

Although laparoscopic colorectal surgery decreases postoperative pain and facilitates a speedier recovery compared with laparotomy, postoperative pain at trocar insertion sites remains a clinical concern. The objective of this study was to assess the effects of a preoperative ultrasound-guided transversus abdominis plane (TAP) block on pain after laparoscopic surgery for colorectal cancer. In total, 58 patients scheduled to undergo laparoscopic surgery following a diagnosis of colorectal cancer were included in this study. The patients were randomized into TAP and control groups; the TAP group patients received a preoperative ultrasound-guided bilateral TAP block with 0.5 mL/kg of 0.25 % bupivacaine, while the control patients received the block with an equal amount of saline. Pain on coughing and at rest was assessed during postanesthetic recovery (PAR; 1 h after surgery) and on postoperative days (PODs) 1 (24 h), 2 (48 h), and 3 (72 h) by an investigator blinded to group allocations using the numeric rating scale (NRS). The primary outcome was pain on coughing on postoperative day (POD) 1. Fifty-five patients were included in the final analysis, including 28 in the TAP and 27 in the control groups. The pain intensity on coughing and at rest during PAR and on PODs 1, 2, and 3 showed no significant differences between groups. Furthermore, there was no significant difference in postoperative opioid consumption, sedation scores, nausea scores at the four time points, complication rates, and length of hospital stay between groups. In colorectal cancer patients undergoing laparoscopic colorectal surgery, a TAP block did not offer enough benefit for clinical efficacy in terms of postoperative pain or analgesic consumption.

The goal of this study was to clarify the efficacy of and indication for re-pushback surgery as secondary treatment for cleft palate. Fifteen patients treated by re-pushback surgery involving intravelar veloplasty (IVV) with buccal mucosal grafting on the nasal surface and followed up more than 6 months were enrolled in this study. Pre- and postoperative velopharyngeal functions were analyzed by perceptual voice analysis, blowing ratio, and nasalance scores during phonation of /i/ and /tsu/. Cephalometric analysis was used to evaluate the relationship between velopharyngeal structure and the outcome of re-pushback surgery. Control data were obtained from the longitudinal files of normal 10-year-old children in Kyushu University Dental Hospital. Eight of 15 patients obtained complete velopharyngeal closure (complete group), five patients improved remarkably (improved group), and no effective result was seen in two patients (ineffective group). Nasality disappeared or remarkably improved after the operation in 13 patients. Effective surgical results were found in 86.7% of the patients. Partial flap necrosis was seen in two patients in whom re-pushback surgery was performed using mucosal palatal flaps instead of mucoperiosteal flaps. Preoperative velar length and the length/depth ratio of the re-pushback group were significantly smaller than the controls, but there was no difference after the operation. Furthermore, the preoperative length/depth ratio of the complete group (ranged more than 100%) was significantly greater than those of the other two groups (ranged less than 100%). Re-pushback surgery by IVV with free mucous grafting on the nasal surface was effective in managing velopharyngeal incompetence secondarily, improving velopharyngeal structure and function.

With a significant increase in the number and complexity of spinal deformity corrective surgeries, blood loss, often requiring massive intraoperative transfusions, becomes a major limiting factor during surgery. This scenario is particularly during posterior vertebral column resection (PVCR), where extensive intraoperative blood loss may pose a major risk to the patient, preventing smooth execution of the procedure. Tranexamic Acid (TXA) has been used in cardiac and orthopedic surgeries, including major spinal surgeries, to reduce blood loss and transfusion requirements for decades. To assess the efficacy and safety of high doses of TXA in posterior spinal deformity corrective surgery, including PVCR procedures. A retrospective study from a single institution. Fifty-nine patients (age range 7 to 46 years old) with spinal deformities undergoing spinal corrective surgeries were included. The patients were divided into two groups: the TXA group (total of 26 patients, including 8 PVCR patients) and the control group (total of 33 patients, including 9 PVCR patients). The analyzed outcome measures included estimated intraoperative blood loss, real blood loss (RBL; blood loss/blood volume×100%), blood transfusion requirements, coagulation parameters, complete blood count, liver function, and renal function. Lower limb vein thrombus, symptomatic pulmonary embolism, symptomatic myocardial infarction, seizures, and acute renal failure were also recorded. Before skin incision, the patients in the TXA group received an intravenous loading dose of 100 mg/Kg over a 20-minute period, followed by a maintenance infusion of 10 mg/Kg/h until skin closure was completed. The patients in the control group received saline infusion of a similar volume. Statistics included estimated intraoperative blood loss, RBL, blood transfusion requirements, coagulation parameters, complete blood count, liver function, and renal function. All patients in this study were also carefully monitored for consciousness level, breathing status, chest tightness or pain, and urine output after surgery. These were done to detect the presence or absence of pulmonary embolism, myocardial infarction, seizures, and acute renal failure. Patients treated with TXA were examined via vascular ultrasound before and after surgery. There were no significant differences in the demographic or surgical traits between the two groups. The blood loss of the patients in the TXA group was 2,441±1,666 mL, whereas that of the control group patients was 4,789±4,719 mL. The difference was statistically significant (p<.05). The average RBL of the patients in the TXA group was 80.6%±49.6% versus 160.8%±163.1% in the control group (p<.05). The blood transfusion requirements for the patients in the TXA group were significantly less than that in the control group (p<.05). Blood loss, RBL, and blood transfusion requirements were all significantly lower in the TXA group, compared with the control group among both PVCR patients and non-PVCR patients. In the TXA group, there was an average of 57.4% reduced blood loss in patients who received PVCR and 39.8% in patients not receiving PVCR. There were no differences in liver and renal functions between the TXA and control groups. There was no lower limb vein thrombus, symptomatic myocardial infarction, symptomatic pulmonary embolism, seizures, or acute renal failure reported in the TXA group. In our study, high doses of TXA have been shown to effectively control blood loss and reduce the transfusion requirement. This effect was more apparent in patients receiving PVCR. No adverse drug reaction was recorded in the study. In the future, prospective randomized controlled trials to validate our results will be necessary. Future studies conducted on older patient cohort may also be necessary to confirm the safety of extending the use of TXA to the older patients. Copyright © 2015 Elsevier Inc. All rights reserved.

Pregnancies among morbidly obese women are associated with serious adverse maternal and neonatal outcomes. Our study objective is to evaluate the effect of bariatric surgery on obstetrical outcomes. We carried out a retrospective cohort study using the healthcare cost and utilization project - Nationwide Inpatient Sample from 2003 to 2011 comparing outcome of births among women who had undergone bariatric surgery with births among women with morbid obesity. Logistic regression was used to estimate the adjusted effect of bariatric surgery on maternal and newborn outcomes. There were 8 475 831 births during the study period (221 580 (2.6%) in morbidly obese women and 9587 (0.1%) in women with bariatric surgery). Women with bariatric surgery were more likely to be Caucasian and ≥35 years old as compared with morbidly obese women. As compared with women with morbid obesity, women with bariatric surgery had lower rates of hypertensive disorders, premature rupture of membrane, chorioamnionitis, cesarean delivery, instrumental delivery, postpartum hemorrhage, and postpartum infection. Induction of labor, postpartum blood transfusions, venous thromboembolisms, and intrauterine fetal growth restriction were more common in the bariatric surgery group. There were no differences observed in preterm births, fetal deaths, or reported congenital anomalies. In general, women who undergo bariatric surgery have improved pregnancy outcomes as compared with morbidly obese women. However, the bariatric surgery group was more likely to have venous thromboembolisms, to require a blood transfusion, to have their labor induced and to experience fetal growth restriction.

The aim of this study was to investigate the efficacy, complication rates, patient satisfaction, and recurrence risks of the incisionless otoplasty technique performed with or without cartilage scoring for correcting the prominent ear in pediatric patients. A total of 49 patients with prominent ears were operated with incisionless otoplasty. In Group 1, 44 ears of 24 patients were operated with incisionless otoplasty without cartilage scoring. In Group 2, 46 ears of 25 patients were operated with incisionless otoplasty with cartilage scoring. For comparison, auriculocephalic distances were measured at three different levels: preoperatively, at the end of surgery, and at 1th and 6th month post-operatively. Patient satisfaction was evaluated using a visual analog scale (VAS). The global esthetic improvement scale (GAIS) was applied by an independent, non-participating plastic surgeon at 6 months after surgery. Prior to surgery and at the end of surgery, no statistically significant difference was observed between the groups in terms of auriculocephalic distances at the three levels. At the and 6th month after surgery, auriculocephalic distances were significantly higher in Group 1. There were no significant differences in VAS results and GAIS values between the groups. The recurrence rate was 9.1% in Group 1 and 4.3% in Group 2. The suture extrusion rate was 18.2% in Group 1 and 13% in Group 2. Although there was a significant difference of 1-2 mm in auriculocephalic distances, our study showed that cartilage scoring is not mandatory to correct the prominent ear in pediatric patients with soft cartilages and to achieve patient and surgeon satisfaction.

Nasal packing is an option for bleeding control after endoscopic sinus surgery and septoplasty. Although new packing materials have been developed, patients still suffer from pain and require additional analgesics treatments. In this study, a prospective, randomized, and double-blind controlled trial was designed to evaluate the effect of fentanyl-soaked packing on pain after endoscopic sinus surgery and septoplasty. One hundred fifty-two patients who underwent nasal surgeries due to chronic rhinosinusitis or nasal septal deviation were enrolled in this study. At the end of operation, 50 mcg fentanyl-soaked biodegradable synthetic polyurethane foams packing Nasopore or Merocel were applied to a group of 79 patients, and saline-soaked ones were applied to another group of 73 patients. To evaluate the influence of fentanyl on postoperative nasal pain, patients' conditions were assessed via means of Numeric Rating Scale, patient satisfaction, and Ramsay Sedation Scale. In addition, symptoms of headache or sore throat and any signs of cardiopulmonary-relevant indicators were monitored. The fentanyl group had significantly decreased Numeric Rating Scale and increased patient satisfaction in every operation type for the majority of postoperative time periods ( P < .05) with reduced postoperative headache and sore throat compared to the control group. The fentanyl group showed a higher score on Ramsay Sedation Scale than the control group ( P < .05 in group including endoscopic sinus surgery). There were no significant differences in cardiopulmonary-relevant indicators between the 2 groups ( P > .05). Fentanyl group showed significantly reduced postoperative pain without serious adverse effects. We suggest that topical fentanyl application to nasal packs can be a useful method to reduce pain during the early postoperative period after endoscopic sinus surgery and septoplasty.

Music has been proposed as a safe, inexpensive, nonpharmacological antistress intervention. The purpose of this study was to determine whether patients undergoing cataract surgery while listening to meditation music experience lower levels of blood pressure and heart rate. Two hundred individuals undergoing cataract surgery participated in the study. Hundred individuals listened to meditation music, through headphones, before and during the operation (intervention group) and 100 individuals received standard care (control group). Patients stress coping skills were measured by the Sense of Coherence Scale (SOC Scale). Systolic and diastolic blood pressure and heart rate were defined as outcome measures. According to the SOC Scale, both groups had similar stress coping skills (mean score: 127.6 for the intervention group and 127.3 for the control group). Before entering the operating room (OR) as well as during surgery the rise in systolic and diastolic pressures was significantly lower in the intervention group (P < 0.001). Among patients receiving antihypertensive therapy, those in the intervention group presented a lower increase only in systolic pressure (P < 0.001) at both time recordings. For those patients in the intervention group who did not receive antihypertensive treatment, lower systolic blood pressure at both time recordings was recorded (P < 0.001) while lower diastolic pressure was observed only during entry to the OR (P = 0.021). Heart rate was not altered between the two groups in any of the recordings. Meditation music influenced patients' preoperative stress with regard to systolic blood pressure. This kind of music can be used as an alternative or complementary method for blood pressure stabilizing in patients undergoing cataract surgery.

Introduction Third molar surgery is one of the most common surgical procedures performed in general dentistry. Post-operative variables such as pain, swelling and trismus are major concerns after impacted mandibular third molar surgery. Use of passive tube drain is supposed to help reduce these immediate post-operative sequelae. The current study was designed to compare the effect of tube drain on immediate post-operative sequelae following impacted mandibular third molar surgery. Aim To compare the post-operative sequelae after surgical removal of impacted mandibular third molar surgery with or without tube drain. Materials and Methods Thirty patients with bilateral impacted mandibular third molars were divided into two groups: Test (with tube drain) and control (without tube drain) group. In the test group, a tube drain was inserted through the releasing incision, and kept in place for three days. The control group was left without a tube drain. The post-operative variables like, pain, swelling, and trismus were calculated after 24 hours, 72 hours, 7 days, and 15 days in both the groups and analyzed statistically using chi-square and t-test analysis. Results The test group showed lesser swelling as compared to control group, with the swelling variable showing statistically significant difference at post-operative day 3 and 7 (p≤ 0.05) in both groups. There were no statistically significant differences in pain and trismus variables in both the groups. Conclusion The use of tube drain helps to control swelling following impacted mandibular third molar surgery. However, it does not have much effect on pain or trismus. PMID:28209003

This study was aimed to compare conventional surgery and surgery assisted by 3D printing technology in the treatment of calcaneal fractures. In addition, we also investigated the effect of 3D printing technology on the communication between doctors and patients. we enrolled 75 patients with calcaneal fracture from April 2014 to August 2016. They were divided randomly into two groups: 35 cases of 3D printing group, 40 cases of conventional group. The individual models were used to simulate the surgical procedures and carry out the surgery according to plan in 3D printing group. Operation duration, blood loss volume during the surgery, number of intraoperative fluoroscopy and fracture union time were recorded. The radiographic outcomes Böhler angle, Gissane angle, calcaneal width and calcaneal height and final functional outcomes including VAS and AOFAS score as well as the complications were also evaluated. Besides, we made a simple questionnaire to verify the effectiveness of the 3D-printed model for both doctors and patients. The operation duration, blood loss volume and number of intraoperative fluoroscopy for 3D printing group was 71.4 ± 6.8 minutes, 226.1 ± 22.6 ml and 5.6 ± 1.9 times, and for conventional group was 91.3 ± 11.2 minutes, 288.7 ± 34.8 ml and 8.6 ± 2.7 times respectively. There was statistically significant difference between the conventional group and 3D printing group (p < 0.05). Additionally, 3D printing group achieved significantly better radiographic results than conventional group both postoperatively and at the final follow-up (p < 0.05). However, No significant difference was noted in the final functional outcomes between the two groups. As for complications, there was no significant difference between the two groups. Furthermore, the questionnaire showed that both doctors and patients exhibited high scores of overall satisfaction with the use of a 3D printing model. This study suggested the clinical feasibility of 3D printing technology in treatment of calcaneal fractures.

Orthopedic surgeries are among the most common and most painful surgeries performed. A multimodal analgesic approach is recommended to reduce opioid consumption, provide effective pain relief, and improve outcomes following surgery. This study examined the efficacy and opioid-sparing effects of parecoxib following major orthopedic surgery. This subset analysis of a large, multicenter, randomized, double-blind, placebo-controlled study of parecoxib examined treatment effects on postoperative pain severity, pain interference with function, opioid consumption, occurrence of opioid-related symptoms, safety, and patient satisfaction following major orthopedic surgery. Pain scores were significantly lower in the parecoxib group (n = 142) compared with placebo (n = 139) on day 2 (-22%; p < 0.001) and day 3 (-17%; p = 0.004). Pain interference with function scores were also significantly lower in the parecoxib group on day 2 (-32%; p < 0.001) and day 3 (-27%; p = 0.003) relative to placebo. Additionally, significantly less supplemental morphine was required in the parecoxib group relative to placebo through 24 h (-28%; p = 0.008) and 48 h (-33%; p < 0.001). Patients in the parecoxib group had a reduced risk of experiencing opioid-related symptoms including fatigue, drowsiness, inability to concentrate, confusion, nausea, constipation, and confusion on day 2 and/or day 3. Finally, more patients receiving parecoxib (42%) rated treatment as "excellent" compared to those receiving placebo (21%). These findings support the use of parecoxib for the management of pain following major orthopedic surgery.

The effects of isoflurane on the determinants of blood flow during Coronary Artery Bypass Graft (CABG) surgery are not completely understood. This study characterized the influence of isoflurane on the diastolic Pressure-Flow (P-F) relationship and Critical Occlusion Pressure (COP) during CABG surgery. Twenty patients undergoing CABG surgery were studied. Patients were assigned to an isoflurane or control group. Hemodynamic and flow measurements during CABG surgery were performed twice (15 minutes after the discontinuation of extracorporeal circulation (T15) and again 15 minutes later (T30)). The zero flow pressure intercept (a measure of COP) was extrapolated from a linear regression analysis of the instantaneous diastolic P-F relationship. In the isoflurane group, the application of isoflurane significantly increased the slope of the diastolic P-F relationship by 215% indicating a mean reduction of Coronary Vascular Resistance (CVR) by 46%. Simultaneously, the Mean Diastolic Aortic Pressure (MDAP) decreased by 19% mainly due to a decrease in the systemic vascular resistance index by 21%. The COP, cardiac index, heart rate, Left Ventricular End-Diastolic Pressure (LVEDP) and Coronary Sinus Pressure (CSP) did not change significantly. In the control group, the parameters remained unchanged. In both groups, COP significantly exceeded the CSP and LVEDP at both time points. We conclude that short-term application of isoflurane at a sedative concentration markedly increases the slope of the instantaneous diastolic P-F relationship during CABG surgery implying a distinct decrease with CVR in patients undergoing CABG surgery.

We aim to review the available literature on obese patients treated with ursodeoxycholic acid (UDCA) in order to prevent gallstone formation after bariatric surgery. A systematic literature search was performed in PubMed, Cochrane library, and Scopus databases, in accordance with the PRISMA guidelines. Eight studies met the inclusion criteria incorporating 1355 patients. Random-effects meta-analysis showed a lower incidence of gallstone formation in patients taking UDCA. Subgroup analysis reported fewer cases of gallstone disease in the UDCA group in relation to different bariatric procedures, doses of administered UDCA, and time from bariatric surgery. Adverse events were similar in both groups. Fewer patients required cholecystectomy in UDCA group. No deaths were reported. The administration of UDCA after bariatric surgery seems to prevent gallstone formation.

Systematic reviews of lumbar fusion outcomes in purely workers' compensation (WC) patient populations have indicated mixed results for efficacy. Recent studies on lumbar fusions in the WC setting have reported return-to-work rates of 26% to 36%, reoperation rates of 22% to 27%, and high rates of persistent opioid use 2 years after surgery. Other types of lumbar surgery in WC populations are also acknowledged to have poorer outcomes than in non-WC. The possibility of improving outcomes by employing a biopsychosocial model with a continuum of care, including postoperative functional restoration in this "at risk" population, has been suggested as a possible solution. To compare objective socioeconomic and patient-reported outcomes for WC patients with different lumbar surgeries followed by functional restoration, relative to matched comparison patients without surgery. A prospective cohort study of chronic disabling occupational lumbar disorder (CDOLD) patients with WC claims treated in an interdisciplinary functional restoration program. A consecutive cohort of 564 patients with prerehabilitation surgery completed a functional restoration and was divided into groups based on surgery type: lumbar fusion (F group, N=331) and nonfusion lumbar spine surgery (NF group, N=233). An unoperated comparison group was matched for length of disability (U group, N=349). Validated patient-reported measures of pain, disability, and depression were administered pre- and postrehabilitation. Socioeconomic outcomes were collected via a structured 1-year "after" interview. All patients completed an intensive, medically supervised functional restoration program combining quantitatively directed exercise progression with a multimodal disability management approach. The writing of this article was supported in part by National Institutes of Health Grant 1K05-MH-71892; no conflicts of interest are noted among the authors. The F group had a longer length of disability compared with the NF and U groups (M=31.6, 21.7, and 25.9 months, respectively, p<.001). There were relatively few statistically significant differences for any socioeconomically relevant outcome among groups, with virtually identical postrehabilitation return-to-work (F=81%, NF=84%, U=85%, p=.409). The groups differed significantly after surgery on diagnosis of major depressive disorder and opioid dependence disorder as well as patient-reported depressive symptoms and pain intensity prerehabilitation. However, no significant differences in patient-reported outcomes were found postrehabilitation. Prerehabilitation opioid dependence disorder significantly predicted lower rates of work return and work retention as well as higher rates of treatment-seeking behavior. Higher levels of prerehabilitation perceived disability and depressive symptoms were significant risk factors for poorer work return and retention outcomes. Lumbar surgery in the WC system (particularly lumbar fusion) have the potential achieve positive outcomes that are comparable to CDOLD patients treated nonoperatively. This study suggests that surgeons have the opportunity to improve lumbar surgery outcomes in the WC system, even for complex fusion CDOLD patients with multiple prior operations, if they control postoperative opioid dependence and prevent an excessive length of disability. Through early referral of patients (who fail to respond to usual postoperative care) to interdisciplinary rehabilitation, the surgeon determining this continuum of care may accelerate recovery and achieve socioeconomic outcomes of relevance to the patient and WC jurisdiction through the combination of surgery and postoperative rehabilitation.

Background Patients scheduled for heart valve surgery should be free of any oral infectious disorders that might pose a risk in the postoperative period. Few studies have been made on the dental conditions of such patients prior to surgery. The present study describes the most frequent prior oral diseases in this population group. Material and Methods A prospective, observational case-control study was designed involving 60 patients (30 with heart valve disease and 30 controls, with a mean age of 71 years in both groups). A dental exploration was carried out, with calculation of the DMFT (decayed, missing and filled teeth) index and recording of the periodontal parameters (plaque index, gingival bleeding index, periodontal pocket depth, and attachment loss). The oral mucosa was also examined, and panoramic X-rays were used to identify possible intrabony lesions. Results Significant differences in bacterial plaque index were observed between the two groups (p<0.05), with higher scores in the patients with valve disease. Probing depth and the presence of moderate pockets were also greater in the patients with valve disease than among the controls (p<0.01). Sixty percent of the patients with valve disease presented periodontitis. Conclusions Patients scheduled for heart valve surgery should be examined for possible active periodontitis before the operation. Those individuals found to have periodontal disease should receive adequate periodontal treatment before heart surgery. Key words:Valve disease, aortic, mitral, heart surgery, periodontitis.

SUMMARY Objective To assess long-term direct medical costs, health care utilization, and mortality following resective surgery in persons with uncontrolled epilepsy. Methods Retrospective longitudinal cohort study of Medicaid beneficiaries with epilepsy from 2000 - 2008. The study population included 7,835 persons with uncontrolled focal epilepsy age 18 to 64 years, with an average follow-up time of 5 years. Of these, 135 received surgery during the study period. To account for selection bias, we used risk-set optimal pairwise matching on a time-varying propensity score, and inverse probability of treatment weighting. Repeated measures generalized linear models were used to model utilization and cost outcomes. Cox proportional hazard was used to model survival. Results The mean direct medical cost difference between the surgical group and control group was $6,806 after risk-set matching. The incidence rate ratio of inpatient, emergency room, and outpatient utilization was lower among the surgical group in both unadjusted and adjusted analyses. There was no significant difference in mortality after adjustment. Among surgical cases, mean annual costs per subject were on average $6,484 lower, and all utilization measures were lower after surgery compared to before. Significance Subjects that underwent epilepsy surgery had lower direct medical care costs and health care utilization. These findings support that epilepsy surgery yield substantial health care cost savings. PMID:26693701

Since oncological outcomes of transanal colorectal tube (TCT) placement, an endoscopic treatment for colorectal cancer (CRC) with acute colorectal obstruction (ACO), remain unknown, this study analyzed long-term outcomes of TCT placement for stage II/III CRC with ACO. Data were retrospectively reviewed from consecutive patients with distal stage II/III CRC who underwent surgery between January 2007 and December 2011 at two Japanese hospitals. One hospital conducted emergency surgery and the other performed TCT placement as the standard treatment for all CRCs with ACO. Propensity score (PS) matching was used to adjust baseline characteristics between two groups. Among 754 patients with distal stage II/III CRC, 680 did not have ACO (non-ACO group) and 74 had ACO (ACO group). The PS matching between both hospitals identified 234 pairs in the non-ACO group and 23 pairs in the ACO group. In the non-ACO group, the surgical quality was equivalent between the two institutions, with no significant differences in overall survival (OS) and disease-free survival (DFS). In the ACO group, the rate of primary resection/anastomosis was higher in the TCT group than in the surgery group (87.0% vs. 26.1%; p < 0.001). No significant differences were noted between the surgery and the TCT groups in OS (5-year OS, 61.9% vs. 51.5%; p=0.490) and DFS (5-year DFS, 45.9% vs. 38.3%; p=0.658). TCT placement can achieve similar long-term outcomes to emergency surgery, with a high rate of primary resection/anastomosis for distal stage II/III colon cancer with ACO.

The objective of this study was to evaluate the efficacy of bilateral endoscopic injection of lidocaine with epinephrine in the sphenopalatine ganglion at the end of endoscopic sinus surgery (ESS) in controlling postoperative pain and rescue analgesic requirements. A prospective, double blinded, placebo-controlled clinical trial of 60 patients with chronic rhinosinusitis (CRS) undergoing general anesthesia for ESS was undertaken. Patients were randomized to receive injection of 2 mL of 2% lidocaine with epinephrine or 2 mL saline at the end of surgery. Postoperatively, patients were observed for 24 hours. Pain severity was reported immediately, 6 hours, and 24 hours after surgery using a 10-cm visual analog scale (VAS). The need of rescue analgesia was recorded and compared between the 2 groups. The 2 groups were matched in demographic and intraoperative details. Postoperative pain severity average was 3.4, 3.0, and 1.6 in the saline group compared to 1.6, 1.7, and 1.0 in the lidocaine group. These differences reached statically significant for the first 2 follow-up intervals. Also, there was significant difference in the whole-day postoperative average score between the 2 groups (2.6 vs 1.4). Twelve patients in the saline group required rescue analgesia compared to 5 in the lidocaine group. The average rescue analgesia dose was 27.5 mg of tramadol in the saline group vs 11.6 in the lidocaine group. These differences were statistically significant. No complications were reported in either group. Sphenopalatine ganglion injection of lidocaine at the end of surgery is safe, simple, noninvasive, and an effective method of short-term pain control after sinus surgery. © 2015 ARS-AAOA, LLC.

The aim of this retrospective investigation was to evaluate the postoperative quality of life after endodontic surgery in maxillary molars when a sinus membrane perforation occurred and platelet concentrates were used. Included patients were treated by microsurgical endodontic treatment in molar and premolar maxillary regions between 2007 and 2010. Patients who fulfilled the inclusion criteria were screened. Data from the quality of life questionnaire were analyzed. The use of plasma rich in growth factors (PRGF) (test group) was compared with a control group when a Schneiderian membrane perforation occurred during endodontic surgery performed with a modern technique in maxillary molars and premolars. A total of 20 patients (12 in the control group and eight in the test group) fulfilled the inclusion criteria. No differences were evaluated at baseline for clinical parameters. Significantly improved patients' quality of life was observed in the test group considering symptoms as swelling, bad breath or taste, and pain. Functional activities were less impaired in the test group and swelling was significantly higher in the control group. In the test group, pain was significantly lower than the control group during the first 6 days after surgery and also, the consumption of painkillers was lower for patients belonging to the test group even if it was not statistically significant. In general, a small sinus membrane perforation (less than 6 mm) during endodontic surgery did not cause severe complications. The use of platelet concentrates could be effective in reducing the impact on patients' quality of life, decreasing pain and surgery side effects as well as swelling.

Purpose The unique properties of remifentanil make it ideal for pediatric use despite a lack of wide randomized clinical trials and fear of adverse events due to its high potency. We aimed to consolidate preliminary conclusions regarding the efficacy of remifentanil use in pediatric scoliosis surgery. Materials and Methods The medical charts of children with idiopathic scoliosis who underwent primary spinal fusion between 1998 and 2007 at a large tertiary university-affiliated hospital were retrospectively reviewed and divided into two groups according to anesthetic regime (remifentanil vs. morphine). Demographic, surgery-related details and immediate postoperative course were recorded and compared. Results All 36 remifentanil children were extubated shortly after termination of surgery, compared to 2 of the 84 patients in the morphine group. The remaining patients in the morphine group were extubated hours after surgery [5.4 hours; standard deviation (SD) 1.7 hours]. Six remifentanil children were spared routine intensive care hospitalization (vs. 2 morphine children-significant difference). Shorter surgeries [5.6 hours (SD 1.82 hours) vs. 7.14 hours (SD 2.15 hours); p=0.0004] were logged for the remifentanil group. To achieve controlled hypotension during surgery, vasodilator agents were used in the morphine group only. A comparison of early postoperative major or minor complication rates (including neurological and pulmonary complications) between the two groups yielded no significant differences. Conclusion Remifentanil use can shorten operating time and facilitate earlier spontaneous ventilation and extubation, with less of a need for intensive care hospitalization and no increase in significant complications.

Perioperative hypothermia can develop easily during shoulder arthroscopy, because cold irrigation can directly influence core body temperature. The authors investigated whether active warming and humidification of inspired gases reduces falls in core body temperature and allows redistribution of body heat in patients undergoing arthroscopic shoulder surgery under general anesthesia. Patients scheduled for arthroscopic shoulder surgery were randomly assigned to receive either room temperature inspired gases using a conventional respiratory circuit (the control group, n = 20) or inspired gases humidified and heated using a humidified and electrically heated circuit (HHC) (the heated group, n = 20). Core temperatures were significantly lower in both groups from 30 min after anesthesia induction, but were significantly higher in the heated group than in the control group from 75 to 120 min after anesthesia induction. In this study the use of a humidified and electrically heated circuit did not prevent core temperature falling during arthroscopic shoulder surgery, but it was found to decrease reductions in core temperature from 75 min after anesthesia induction.

Multimodal analgesia is advocated for perioperative pain management to reduce opioid use and its associated adverse effects. Serotonin and norepinephrine are involved in the modulation of endogenous analgesic mechanisms via descending inhibitory pain pathways in the brain and spinal cord. An increase in serotonin and norepinephrine may increase inhibition of nociceptive input and improve pain relief. Duloxetine, a selective serotonin and norepinephrine reuptake inhibitor, has demonstrated efficacy in chronic pain conditions such as painful diabetic neuropathy and post-herpetic neuralgia. The objective of the study was to evaluate the efficacy of duloxetine in reducing morphine requirements in patients after knee replacement surgery. Fifty patients received either two doses of oral duloxetine 60 mg (2 h before surgery and on first postoperative day) or placebo. All patients received patient-controlled analgesia with morphine for 48 h after operation. Pain and adverse effects were assessed at 0.5, 1, 2, 6, 12, 24, and 48 h after surgery on an 11-point numeric rating scale. Twenty-three patients in the duloxetine group and 24 patients in the placebo group completed the study. Morphine requirements during the 48 h after surgery were significantly lower in the duloxetine group [19.5 mg, standard deviation (sd) 14.5 mg] compared with the placebo group (30.3 mg, sd 18.1 mg) (P=0.017). There were no statistically significant differences between the groups in pain scores (at rest and on movement) or in adverse effects. Perioperative administration of duloxetine reduced postoperative morphine requirements during the first 48 h after knee replacement surgery, without significant adverse effects.

Aims and Objectives: (1) To evaluate the need of antibiotics in periodontal surgeries in reducing postsurgical infections and explore if antibiotics have any key role in reducing or eliminating inflammatory complications. (2) To establish the incidence of postoperative infections in relation to type of surgery and determine those factors, which may affect infection rates. Materials and Methods: A prospective randomized double-blind cross over clinical study was carried out for a period of 1-year with predefined inclusion and exclusion criteria. All the patients included in the study for any periodontal surgery were randomly divided into three categories: Group A (prophylactic), Group B (therapeutic), and Group C (no antibiotics). Patients were followed up for 1-week after surgery on the day of suture removal and were evaluated for pain, swelling, fever, infection, delayed wound healing and any other significant findings. Appropriate statistical analysis was carried out to evaluate the objectives and P < 0.05 was considered as statistically significant. Results: No infection was reported in any of 90 sites. Patients reported less pain and postoperative discomfort when prophylactic antibiotics were given. However, there were no statistical significant differences between the three groups. Summary and Conclusion: There was no postoperative infection reported in all the 90 sites operated in this study. The prevalence of postoperative infections following periodontal surgery is <1% and this low risk does not justify the routine use of systemic antimicrobials just to prevent infections. Use of prophylactic antibiotics may have role in prevention of inflammatory complication, but again not infection. PMID:25425817

Background: Bone conduction (BC) threshold depression is not always by means of sensory neural hearing loss and sometimes it is an artifact caused by middle ear pathologies and ossicular chain problems. In this research, the influences of ear surgeries on bone conduction were evaluated. Materials and Methods: This study was conducted as a clinical trial study. The ear surgery performed on 83 patients classified in four categories: Stapedectomy, tympanomastoid surgery and ossicular reconstruction partially or totally; Partial Ossicular Replacement Prosthesis (PORP) and Total Ossicular Replacement Prosthesis (TORP). Bone conduction thresholds assessed in frequencies of 250, 500, 1000, 2000 and 4000 Hz pre and post the surgery. Results: In stapedectomy group, the average of BC threshold in all frequencies improved approximately 6 dB in frequency of 2000 Hz. In tympanomastoid group, BC threshold in the frequency of 500, 1000 and 2000 Hz changed 4 dB (P-value < 0.05). Moreover, In the PORP group, 5 dB enhancement was seen in 1000 and 2000 Hz. In TORP group, the results confirmed that BC threshold improved in all frequencies especially at 4000 Hz about 6.5 dB. Conclusion: In according to results of this study, BC threshold shift was seen after several ear surgeries such as stapedectomy, tympanoplasty, PORP and TORP. The average of BC improvement was approximately 5 dB. It must be considered that BC depression might happen because of ossicular chain problems. Therefore; by resolving middle ear pathologies, the better BC threshold was obtained, the less hearing problems would be faced. PMID:24381615

Although many studies in the cardiothoracic literature exist about the relationship between clopidogrel and postoperative bleeding, there is scarce data in the general surgery literature. We assessed whether there are increased bleeding complications, morbidity, mortality, and resource utilization in patients who are on clopidogrel (Plavix) within 1 week before undergoing a general surgery procedure. Fifty consecutive patient charts were retrospectively reviewed after identifying patients who had pharmacy orders for clopidogrel and who underwent a general surgery procedure between 2003 and 2007. Patients who took clopidogrel within 6 days before surgery (group I, n = 28) were compared with patients who stopped clopidogrel for 7 days or more (group II, n = 22). A larger percentage of patients who took their last dose of clopidogrel within 1 week of surgery (21.4% vs 9.5%) had significant bleeding after surgery requiring blood transfusion. However, there were no significant differences between the groups in operative or postoperative blood transfusions (P = 0.12, 0.53), decreases in hematocrit (P = 0.21), hospital stay (P = 0.09), intensive care unit stay (P = 0.41), late complications (P = 0.45), or mortality (P = 0.42). Although our cohort is limited in size, these results suggest that in the case of a nonelective general surgery procedure where outcomes depend on timely surgery, clopidogrel taken within 6 days before surgery should not be a reason to delay surgery. However, careful attention must be paid to meticulous hemostasis, and platelets must be readily available for transfusion in the operating room.

OBJECTIVE: To evaluate the effect of pre-operative administration of ibuprofen on post-operative pain control vs. early post-operative administration for hand surgery procedures performed under local anaesthesia in ambulatory care. METHODS: Candidates to trigger finger release by De Quervain tenosynovitis and carpal tunnel operation under local anesthesia were enrolled in the study. Group A received 400 mg ibuprofen before the operation and placebo after the procedure; group B received placebo before the operation and ibuprofen 400 mg at the end of the procedure; both groups received ibuprofen 400 mg every 6h thereafter. Visual analogue scale (VAS) was measured at fixed times before and every 6h after surgery, for a total follow-up of 18h. RESULTS: Groups were similar according to age, gender and type of surgery. Median VAS values did not produce any statistical significance, while there was a statistically significant difference on pre-operative and early post-operative VAS values between groups (A -8.53 mm vs. B 3.36 mm, p=0.0085). CONCLUSION: Average pain levels were well controlled by local anesthesia and post-operative ibuprofen analgesia. Pre-operative ibuprofen administration can contribute to improve early pain management. Level of Evidence II, Therapeutic Studies. PMID:26327799
