Most studies examining psychosocial changes after cosmetic surgery have short follow-up periods and therefore provide limited information about long-term effects of such surgery. Moreover, studies that identify whether preexisting patient characteristics are associated with poor psychosocial outcomes after cosmetic surgery are lacking. The current study provides information about both of these issues. Questionnaire data from 130 female Norwegian cosmetic surgery patients were obtained before and 5 years after surgery. The questionnaire consisted of measures on appearance satisfaction, self-esteem, psychological problems, and patients' evaluation of the outcome of surgery. Data from a representative sample of 838 Norwegian women, aged 22 to 55 years, were used for comparison purposes. Analyses revealed an improvement in both general appearance satisfaction and satisfaction with the body part operated on 5 years after surgery. A small increase in self-esteem was observed as well. High rates of preoperative psychological problems and low self-esteem were related to more negative changes in some of the psychosocial measures after surgery compared with patients with better psychological health. Furthermore, factors associated with the actual decision to undergo surgery were related to changes in psychological health and patients' evaluation of the outcome of surgery. This study indicates that cosmetic surgery has positive long-term effects on appearance-related variables. However, surgeons should be particularly aware of patients with psychological problems, as these may compromise patient satisfaction with the effects of cosmetic surgery. Factors affecting the decision itself to undergo cosmetic surgery may also be relevant for subsequent psychosocial outcomes. Therapeutic, II.

The authors present a systematic review of randomized and observational, retrospective and prospective studies to compare between robotic surgery as opposed to laparoscopic, abdominal, and vaginal surgery for the treatment of both benign and malignant gynecologic indications. The comparison focuses on operative times, surgical outcomes, and surgical complications associated with the various surgical techniques. PubMed was the main search engine utilized in search of study data. The review included studies of various designs that included at least 25 women who had undergone robotic gynecologic surgery. Fifty-five studies (42 comparative and 13 non-comparative) met eligibility criteria. After careful analysis, we found that robotic surgery was consistently connected to shorter post-surgical hospitalization when compared to open surgery, a difference less significant when compared to laparoscopic surgery. Also, it seems that robotic surgery is highly feasible in gynecology. There are quite a few inconsistencies regarding operative times and estimated blood loss between the different approaches, though in the majority of studies estimated blood loss was lower in the robotic surgery group. The high variance in operative times resulted from the difference in surgeon’s experience. The decision whether robotic surgery should become mainstream in gynecological surgery or remain another surgical technique in the gynecological surgeon’s toolbox requires quite a few more randomized controlled clinical trials. In any case, in order to bring robotic surgery down to the front row of surgery, training surgeons is by far the most important goal for the next few years. PMID:28467761

It remains controversial whether open or laparoscopic surgery should be indicated for elderly patients with colorectal cancer and a poor performance status. In those patients aged 80 years or older with Eastern Cooperative Oncology Group performance status score of 2 or greater who received elective surgery for stage 0 to stage III colorectal adenocarcinoma and had no concomitant malignancies and who were enrolled in a multicenter case-control study entitled "Retrospective study of laparoscopic colorectal surgery for elderly patients" that was conducted in Japan between 2003 and 2007, background characteristics and short-term and long-term outcomes for open surgery and laparoscopic surgery were compared. Of the 398 patients included, 295 underwent open surgery and 103 underwent laparoscopic surgery. There were no significant differences in the baseline characteristics between open surgery and laparoscopic surgery patients, except for previous abdominal surgery and TNM stage. The median operation duration was shorter with open surgery (open surgery, 153 min; laparoscopic surgery, 202 min; P < 0.001), and less blood loss occurred with laparoscopic surgery (median open surgery, 109 g; median laparoscopic surgery, 30 g; P < 0.001). An operation duration of 180 min or more (odds ratio, 1.97; 95 % confidence interval, 1.17-3.37; P = 0.011) and selection of laparoscopic surgery (odds ratio, 0.41; 95 % confidence interval, 0.22-0.75; P = 0.003) were statistically significant in the multivariate analysis for postoperative morbidity. Moreover, laparoscopic surgery did not result in an inferior overall survival rate compared with open surgery (log-rank test P = 0.289, 0.278, 0.346, 0.199, for all-stage, stage 0-I, stage II, and stage III disease, respectively). Laparoscopic surgery in elderly colorectal cancer patients with a poor performance status is safe and not inferior to open surgery in terms of overall survival.

Studies exploring the impact of pre-surgery psychiatric status as a predictor of health related quality of life (QOL) after bariatric surgery have been limited to short-term follow-up and variable use of psychosocial measures. We examined the effect of pre-operative psychiatric factors on QOL and weight loss 2-years after surgery. 156 patients participated in this prospective cohort study, the Toronto Bariatric Psychosocial Cohort Study, between 2010 and 2014. Patients were assessed pre-surgery for demographic factors, weight, psychiatric diagnosis using the MINI International Neuropsychiatric Interview and symptom measures for QOL, depression and anxiety at pre-surgery and at 1 and 2years post-surgery. At 2-years post-bariatric surgery, patients experienced a significant decrease in mean weight (-48.43kg, 95% [-51.1, -45.76]) and an increase only in physical QOL (+18.91, 95% [17.01, 20.82]) scores as compared to pre-surgery. Multivariate regression analysis identified pre-surgery physical QOL score (p<0.001), younger age (p=0.005), and a history of a mood disorder as significant predictors of physical QOL. Only a history of a mood disorder (p=0.032) significantly predicted mental QOL (p=0.006). Pre-surgery weight (p<0.001) and a history of a mood disorder (p=0.047) were significant predictors of weight loss 2-years post-surgery. Bariatric surgery had a sustained impact on physical QOL but not mental QOL at 2-years post-surgery. A history of mood disorder unexpectedly increased physical QOL scores and weight loss following surgery. Further research is needed to determine if these results are due to bariatric surgery candidate selection within this program. Copyright © 2017 Elsevier Inc. All rights reserved.

Right ventricle function significantly decreases after coronary artery bypass surgery; as one of the likely causes, such a condition is attributed to the use of cardiopulmonary pump (CPB). Because nowadays there is a tendency toward increasing use of off-pump coronary artery bypass (OPCAB) surgery, this study was conducted to evaluate the right ventricle function after this type of surgery using strain and strain rate imaging (SRI) echocardiography. This study was conducted on 30 patients, candidate for elective OPCAB surgery, between 2011 and 2012. Standard echocardiography was performed before the surgery and the right ventricle function was examined using strain and SRI echocardiography. Then patient underwent surgery, 6 days and 3 months after surgery they underwent echocardiography again and the results obtained from the three stages were compared with each other. Participants included 30 patients (23 males and 7 females) with a mean age of 66±11 years. Compared to the prior of the surgery, 6 days and 3 months after the surgery there was a significant decrease in tricuspid annular plane systolic excursion (TAPSE), tissue Doppler imaging (TDI) at the lateral annulus of tricuspid valve, and strain and SRI of right ventricle. However, the values obtained 3 months after surgery were significantly higher than those obtained after 6 days. In other words, the right ventricle function 6 days after the surgery had dropped, however some of the values recovered 3 months after the surgery. The findings of this study are consistent with other studies in this field and showed that after coronary artery surgery a decline occurs in right ventricular function. However, more detailed quantitative strain and SRI parameters which were measured in our study showed that at the early days after the OPCAB surgery there is a decline in the right ventricle function which is relatively reversible at longer intervals (3 months after surgery).

The authors sought to compare the clinical outcomes of simultaneous versus sequential ptosis and strabismus surgery in children. Retrospective, single-center cohort study of children requiring both ptosis and strabismus surgery on the same eye. Simultaneous surgeries were performed during a single anesthetic event; sequential surgeries were performed at least 7 weeks apart. Outcomes were ptosis surgery success (margin reflex distance 1 ≥ 2 mm, good eyelid contour, and good eyelid crease); strabismus surgery success (ocular alignment within 10 prism diopters of orthophoria and/or improved head position); surgical complications; and reoperations. Fifty-six children were studied, 38 had simultaneous surgery and 18 sequential. Strabismus surgery was performed first in 38/38 simultaneous and 6/18 sequential cases. Mean age at first surgery was 64 months, with mean follow up 27 months. A total of 75% of children had congenital ptosis; 64% had comitant strabismus. A majority of ptosis surgeries were frontalis sling (59%) or Fasanella-Servat (30%) procedures. There were no significant differences between simultaneous and sequential groups with regards to surgical success rates, complications, or reoperations (all p > 0.28). In the first comparative study of simultaneous versus sequential ptosis and strabismus surgery, no advantage for sequential surgery was seen. Despite a theoretical risk of postoperative eyelid malposition or complications when surgeries were performed in a combined manner, the rate of such outcomes was not increased with simultaneous surgeries. Performing ptosis and strabismus surgery together appears to be clinically effective and safe, and reduces anesthesia exposure during childhood.

To investigate influences of 3% diquafosol sodium ophthalmic solution (DQS) on ocular surface after cataract surgery and effects on postoperative dry eye. This study had two consecutive prospective study phases. The former was an observational study from before cataract surgery to 4 weeks after surgery and the latter was a randomized open-label study from 4 to 8 weeks after surgery. Subjects were 433 eyes of 433 patients undergoing cataract surgery with intraocular lens implantation. Dry eye examination of tear breakup time (BUT), corneal and conjunctival fluorescein staining scores, total subjective symptom score (12 symptoms), and Schirmer I test were conducted before surgery and 4 weeks after surgery. Patient demographics and these examination results were used to analyze risk factors to predict postoperative dry eye. In a randomized study, 154 eyes diagnosed with dry eye postoperatively were applied either DQS or artificial tears (AT) six times daily for 4 weeks. The data of the examinations were compared. At 4 weeks after surgery, BUT was shortened significantly ( P =0.036), fluorescein staining score increased significantly ( P =0.012), but total subjective symptom score was significantly improved ( P <0.001). The majority of postoperative dry eye was shortened BUT type (53.1%). The dry eye prevalence after surgery decreased (55.7%) compared with before surgery (69.7%). Females and the patient with dry eye symptoms before surgery had significant risk factors for postoperative dry eye. In a randomized study, BUT was significantly prolonged in the DQS group ( P =0.015), but not in the AT group. Fluorescein staining score was significantly improved in both groups ( P <0.001). Total subjective symptom score was significantly decreased in the AT group ( P <0.001), but not in the DQS group. Our study suggests that cataract surgery has harmful effects on tear film stability and ocular surface, and DQS has a capability to improve them.

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

SUMMARY OBJECTIVE To examine national trends of pediatric epilepsy surgery usage in the United States between 1997 and 2009. METHODS We performed a serial cross-sectional study of pediatric epilepsy surgery using triennial data from the Kids’ Inpatient Database from 1997 to 2009. The rates of epilepsy surgery for lobectomies, partial lobectomies, and hemispherectomies in each study year were calculated based on the number of prevalent epilepsy cases in the corresponding year. The age-race-sex adjusted rates of surgeries were also estimated. Mann-Kendall trend test was used to test for changes in the rates of surgeries over time. Multivariable regression analysis was also performed to estimate the effect of time, age, race, and sex on the annual incidence of epilepsy surgery. RESULTS The rates of pediatric epilepsy surgery significantly increased from 0.85 epilepsy surgeries per 1,000 children with epilepsy in 1997 to 1.44 epilepsy surgeries per 1,000 children with epilepsy in 2009. An increment in the rates of epilepsy surgeries was noted across all age groups, in boys and girls, all races, and all payer types. The rate of increase was lowest in blacks and in children with public insurance. The overall number of surgical cases for each study year was lower than 35% of children who were expected to have surgery, based on the estimates from the Connecticut Study of Epilepsy. SIGNIFICANCE In contrast to adults, pediatric epilepsy surgery numbers have increased significantly in the past decade. However, epilepsy surgery remains an underutilized treatment for children with epilepsy. In addition, black children and those with public insurance continue to face disparities in the receipt of epilepsy surgery. PMID:25630252

This article reviews the literature regarding the impact of cosmetic surgery on health-related quality of life (QOL). Studies were identified through PubMed/Medline and PsycINFO searches from January 1960 to December 2011. Twenty-eight studies were included in this review, according to specific selection criteria. The procedures and tools employed in cosmetic surgery research studies were remarkably diverse, thus yielding difficulties with data analysis. However, data indicate that individuals undergoing cosmetic surgery began with lower values on aspects of QOL than control subjects, and experienced significant QOL improvement post-procedurally, an effect that appeared to plateau with time. Despite the complexity of measuring QOL in cosmetic surgery patients, most studies showed an improvement in QOL after cosmetic surgery procedures. However, this finding was clouded by measurement precision as well as heterogeneity of procedures and study populations. Future research needs to focus on refining measurement techniques, including developing cosmetic surgery-specific QOL measures.

Gastrointestinal surgery is associated with a high incidence of infectious complications. Selective decontamination of the digestive tract is an antimicrobial prophylaxis regimen that aims to eradicate gastrointestinal carriage of potentially pathogenic microorganisms and represents an adjunct to regular prophylaxis in surgery. Relevant studies were identified using bibliographic searches of MEDLINE, EMBASE, and the Cochrane database (period from 1970 to November 1, 2012). Only studies investigating selective decontamination of the digestive tract in gastrointestinal surgery were included. Two randomized clinical trials and one retrospective case-control trial showed significant benefit in terms of infectious complications and anastomotic leakage in colorectal surgery. Two randomized controlled trials in esophageal surgery and two randomized clinical trials in gastric surgery reported lower levels of infectious complications. Selective decontamination of the digestive tract reduces infections following esophageal, gastric, and colorectal surgeries and also appears to have beneficial effects on anastomotic leakage in colorectal surgery. We believe these results provide the basis for a large multicenter prospective study to investigate the role of selective decontamination of the digestive tract in colorectal surgery.

Obstetric fistula is treatable by surgery, although access is usually limited, particularly in the context of conflict. This study examines the profile of women attending fistula repair surgery in three hospitals in Somalia. A cross-sectional study was conducted in Somalia from August to September 2016. Structured questionnaires were administered to 81 women who registered for fistula repair surgery in the Garowe, Daynile, and Kismayo General Hospitals in Somalia. Findings revealed that 70.4% of the study participants reported obstetric labor as the cause of their fistula, and 29.6% reported iatrogenic causes. Regarding the waiting time for the repair surgery, 45% waited for the surgery for over one year, while the rest received the surgery within a year. The study suggests that training for fistula surgery has to be provided for healthcare professionals in Somalia, fistula centers should be established, and access to these facilities has to be guaranteed for all patients who need these services.

The need for cataract surgery is expected to rise dramatically in the future due to the increasing proportion of elderly citizens and increasing demands for optimum visual function. The aim of this study was to provide an evidence-based recommendation for the indication of cataract surgery based on which group of patients are most likely to benefit from surgery. A systematic literature search was performed in the MEDLINE, CINAHL, EMBASE and COCHRANE LIBRARY databases. Studies evaluating the outcome after cataract surgery according to preoperative visual acuity and visual complaints were included in a meta-analysis. We identified eight observational studies comparing outcome after cataract surgery in patients with poor (<20/40) and fair (>20/40) preoperative visual acuity. We could not find any studies that compared outcome after cataract surgery in patients with few or many preoperative visual complaints. A meta-analysis showed that the outcome of cataract surgery, evaluated as objective and subjective visual improvement, was independent on preoperative visual acuity. There is a lack of scientific evidence to guide the clinician in deciding which patients are most likely to benefit from surgery. To overcome this shortage of evidence, many systems have been developed internationally to prioritize patients on waiting lists for cataract surgery, but the Swedish NIKE (Nationell Indikationsmodell för Katarakt Ekstraktion) is the only system where an association to the preoperative scoring of a patient has been related to outcome of cataract surgery. We advise that clinicians are inspired by the NIKE system when they decide which patients to operate to ensure that surgery is only offered to patients who are expected to benefit from cataract surgery. © 2015 The Authors.

The purpose of the present study was to use a prospectively collected data to evaluate the rate of incidental durotomy (ID) during lumbar surgery and determine the associated risk factors by using univariate and multivariate analysis. We retrospectively reviewed 2184 patients who underwent lumbar surgery from January 1, 2009 to December 31, 2011 at a single hospital. Patients with ID (n=97) were compared with the patients without ID (n=2019). The influences of several potential risk factors that might affect the occurrence of ID were assessed using univariate and multivariate analyses. The overall incidence of ID was 4.62%. Univariate analysis demonstrated that older age, diabetes, lumbar central stenosis, posterior approach, revision surgery, prior lumber surgery and minimal invasive surgery are risk factors for ID during lumbar surgery. However, multivariate analysis identified older age, prior lumber surgery, revision surgery, and minimally invasive surgery as independent risk factors. Older age, prior lumber surgery, revision surgery, and minimal invasive surgery were independent risk factors for ID during lumbar surgery. These findings may guide clinicians making future surgical decisions regarding ID and aid in the patient counseling process to alleviate risks and complications. Copyright © 2015 Elsevier B.V.

The microflap technique is a standard procedure for the treatment of vocal fold polyps. Angiolytic laser surgery carried out under topical anesthesia is an alternative method for vocal polyp removal. However, it is not clear whether angiolytic laser surgery has the same effects on vocal outcomes as the microflap technique because of a lack of studies comparing both procedures. In the current study, vocal outcomes after both procedures were compared to clarify the effects of angiolytic laser surgery for vocal polyp removal. Vocal outcomes were reviewed for patients who underwent angiolytic laser surgery (n=20, laser group) or microflap surgery (n=34, microflap group) for vocal polyp removal. The data analyzed included patient and lesion characteristics, number of surgeries required for complete resolution, and aerodynamic and acoustic examinations before and after surgery. In the laser surgery group, complete resolution of the lesion was achieved with a single procedure in 17 cases (85%) and with two procedures in 3 cases (15%). Postoperative aerodynamic and acoustic parameters demonstrated significant improvement compared to preoperative parameters in both the laser surgery group and the microflap surgery group. There were no significant differences in any postoperative aerodynamic and acoustic parameters between the two groups. The current retrospective study demonstrated that angiolytic laser surgery achieved complete resolution of vocal polyps within two procedures. Postoperative effects on aerodynamic and acoustic functions were similar to those after microflap surgery. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

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

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

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

Different surgical procedures impose different physical demands on surgeons and high prevalence rates of neck and shoulder pain have been reported among general surgeons. Past research has examined electromyography in surgeons mainly during simulated conditions of laparoscopic and open surgery but not during real-time operations and not for long durations. The present study compares the neck-shoulder muscle activities in three types of surgery and between different surgeons. The relationships of postural muscle activities to musculoskeletal symptoms and personal factors also are examined. Twenty-five surgeons participated in the study (23 men). Surface electromyography (EMG) was recorded in the bilateral cervical erector spinae, upper trapezius, and anterior deltoid muscles during three types of surgical procedures: open, laparoscopic, and endovascular. In each procedure, EMG data were captured for 30 min to more than 1 h. The surgeons were asked to rate any musculoskeletal symptoms before and after surgery. The present study showed significantly higher muscle activities in the cervical erector spinae and upper trapezius muscles in open surgery compared with endovascular and laparoscopic procedures. Muscle activities were fairly similar between endovascular and laparoscopic surgery. The upper trapezius usually has an important role in stabilizing both the neck and upper limb posture, and this muscle also recorded higher activities in open compared with laparoscopic and endovascular surgeries. Surgeons reported similar degrees of musculoskeletal symptoms in open and laparoscopic surgeries, which were higher than endovascular surgery. The present study showed that open surgery imposed significantly greater physical demands on the neck muscles compared with endovascular and laparoscopic surgeries. This may be due to the lighter manual task demands of these minimally invasive surgeries compared with open procedures, which generally required more dynamic movements and more forceful exertions.

Background The goal of this study was to detect the predictors of chronic pain at 6 months after thoracic surgery from a comprehensive evaluation of demographic, psychosocial, and surgical factors. Methods Thoracic surgery patients were enrolled 1 week before surgery and followed-up 6 months post-surgery in this prospective, observational study. Comprehensive psychosocial measurements were assessed before surgery. The presence and severity of pain was assessed at 3 and 6 months after surgery. One-hundred seven patients were assessed during the first 3 days after surgery and 99 (30 thoracotomy and 69 video-assisted thoracoscopic surgery, thoracoscopy) patients completed the 6 months follow-up. Patients with vs without chronic pain related to thoracic surgery at 6 months were compared. Results Both incidence (p = 0.37) and severity (p = 0.97) of surgery-related chronic pain at 6 months were similar after thoracotomy (33%, 95% confidence interval [CI]: 17% to 53%, 3.3 ± 2.1) and thoracoscopy (25%, 95% CI: 15% to 36%, 3.3 ± 1.7). Both frequentist and Bayesian multivariate models revealed that severity of acute pain (numerical rating scale, 0–10) is the measure associated with chronic pain related to thoracic surgery. Psychosocial factors and quantitative sensory testing were not predictive. Conclusions There was no difference in the incidence and severity of chronic pain at 6 months in patients undergoing thoracotomy versus thoracoscopy. Unlike other post-surgical pain conditions, none of the pre-operative psychosocial measurements were associated with chronic pain after thoracic surgery. PMID:28248713

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.

Frozen shoulder is a potential complication after shoulder surgery. It is a clinical condition that is often associated with marked disability and can have a profound effect on the patient's quality of life. The incidence, etiology, pathology and prognostic factors of postoperative frozen shoulder after shoulder surgery are not known. The purpose of this explorative study was to determine the incidence of postoperative frozen shoulder after various operative shoulder procedures. A second aim was to identify prognostic factors for postoperative frozen shoulder after shoulder surgery. 505 consecutive patients undergoing elective shoulder surgery were included in this prospective cohort study. Follow-up was 6 months after surgery. A prediction model was developed to identify prognostic factors for postoperative frozen shoulder after shoulder surgery using the TRIPOD guidelines. We nominated five potential predictors: gender, diabetes mellitus, type of physiotherapy, arthroscopic surgery and DASH score. Frozen shoulder was identified in 11% of the patients after shoulder surgery and was more common in females (15%) than in males (8%). Frozen shoulder was encountered after all types of operative procedures. A prediction model based on four variables (diabetes mellitus, specialized shoulder physiotherapy, arthroscopic surgery and DASH score) discriminated reasonably well with an AUC of 0.712. Postoperative frozen shoulder is a serious complication after shoulder surgery, with an incidence of 11%. Four prognostic factors were identified for postoperative frozen shoulder: diabetes mellitus, arthroscopic surgery, specialized shoulder physiotherapy and DASH score. The combination of these four variables provided a prediction rule for postoperative frozen shoulder with reasonable fit. Level II, prospective cohort study.

Although reoperation rates for upper lid retraction surgery for thyroid eye disease (TED) typically range between 8% and 23%, there is little literature describing the outcomes of these second operations. In this retrospective observational cohort study, all patients that underwent surgery for upper eyelid retraction over a 14-year period at a single institution were included. Cases were included if a second eyelid retraction surgery was performed during the study period. Success of surgery was defined as a marginal reflex distance (MRD1) of 2.5 to 4.5 mm in each eye and less than 1 mm difference in MRD1 between the eyes. Overcorrection and undercorrection were defined as above and below these bounds, respectively. 72 eyes in 49 patients were included in the study. The mean age was 56.6 (±11.5) years. By definition, all patients had at least 1 lid lengthening surgery for upper eyelid retraction, and at least 1 subsequent surgery. For this second surgery, 61 eyes (85%) underwent retraction surgery and 11 eyes (15%) underwent ptosis surgery. After this second operation, 31% were undercorrected and 33% were overcorrected. A third surgery was performed in 19 eyes (25%), 12 had surgery for residual retraction and 7 for ptosis. After the third operation 10% of eyes were under corrected and 11% were over corrected. Four patients underwent a fourth surgery: one for retraction and three for ptosis. Success was noted in 35% after the second surgery and 44% after the third. Surgical success in eyelid retraction surgery increases from a second to a third consecutive surgery, and residual asymmetry was roughly equally distributed between over- and undercorrection.

Robotic colorectal surgery is an emerging field and may offer a solution to some of the difficulties inherent to conventional laparoscopic surgery. The aim of this review is to provide a comprehensive and critical analysis of the available literature on the use of robotic technology in colorectal surgery. Studies reporting outcomes of robotic colorectal surgery were identified by systematic searches of electronic databases. Outcomes examined included operating time, length of stay, blood loss, complications, cost, oncological outcome, and conversion rates. Seventeen Studies (nine case series, seven comparative studies, one randomized controlled trial) describing 288 procedures were identified and reviewed. Study heterogeneity precluded a meta-analysis of the data. Robotic procedures tend to take longer and cost more, but may reduce the length of stay, blood loss, and conversion rates. Complication profiles and short-term oncological outcomes are similar to laparoscopic surgery. Robotic colorectal surgery is a promising field and may provide a powerful additional tool for optimal management of more challenging pathology, including rectal cancer. Further studies are required to better define its role. © 2010 The Authors. Colorectal Disease © 2010 The Association of Coloproctology of Great Britain and Ireland.

Impact of an Interactive Vascular Surgery Web-Based Educational Curriculum on Surgical Trainee Knowledge and Interest.

PubMed

Zayed, Mohamed A; Lilo, Emily A; Lee, Jason T

The surgical council on resident education developed an online competency-based self-study curriculum for general surgery residency trainees. Vascular surgery trainees are yet to have a similarly validated and readily accessible self-study curriculum. We sought to determine the effect of an interactive online vascular surgery curriculum on trainee knowledge and interest in vascular surgery. Over 15 months, 53 trainees (36 medical students and 16 surgical residents) performing a vascular surgery rotation were enrolled in a prospective, randomized, 2-cohort study. Before starting a 4-week rotation, trainee baseline demographics were collected, and a pretest was administered to evaluate baseline vascular surgery knowledge. During the same study period, 31 trainees (GROUP 1) were randomized to an interactive online curriculum with weekly reading assignments, and 21 trainees (GROUP 2) did not have access to the online curriculum. At the conclusion, all trainees received a posttest and survey to evaluate any change in vascular surgery knowledge and interest. Although 26.8% of trainees predicted that online computer modules would be a beneficial learning tool, most of trainees indicated textbook reading and case discussions are preferred. Analysis of GROUPS 1 and 2 revealed no significant differences in the average trainee age, training level, sex, or number of surgical cases observed during the rotation. Improvement in vascular surgery knowledge in GROUP 1 was significantly higher compared to GROUP 2 (average increase in posttest scores of 16.1% vs 6.6%, p = 0.009). New interest in vascular surgery was increased by 22.2% in GROUP 1, but was decreased by 40% in GROUP 2 (p < 0.001). Basic vascular surgery principles can be efficiently introduced through an interactive online curriculum. This type of self-study can improve trainee knowledge, and foster interest in vascular surgery. As in other specialties, a standardized and validated online vascular surgery curriculum should be developed for emerging trainees. Published by Elsevier Inc.

Olfactory outcomes as well as oronasal postoperative complications of transsphenoidal pituitary surgery have not been well studied. The objective of this study was to investigate nasal symptoms including olfactory function as well as quality of life following transsphenoidal pituitary surgery. The study is designed as a prospective cohort study set in a single tertiary hospital. A total of 53 patients with pituitary adenomas were included. All patients underwent pituitary surgery with the right-sided endonasal transsphenoidal approach. Outcomes were assessed with the Chinese version of the Medical Outcomes Study Short Form-36 (SF-36) to survey patient health, the Chinese version of the 22-item Sinonasal Outcome Test (SNOT-22), and a Toyota and Takagi (T&T) olfactometer. Assessments were carried out before surgery and at 1 week, and 1 and 4 months after surgery. The overall SF-36 scores were significantly lower, but the SNOT-22 scores were higher at 1 week and 1 month postoperatively compared with baseline (all P < 0.001). The results of T&T olfactometer testing showed that there was a significant decline in the ability to detect odors postoperatively, even at 4 months. Multivariate linear regression analysis showed that lower education level, partial tumor removal, and longer duration of surgery were independent risk factors for a higher SNOT-22 score at 1 week after surgery. The findings show that microscopic endonasal transsphenoidal pituitary surgery impairs olfactory function in most patients for at least 4 months after surgery.

We conducted this study to investigate how physical and cognitive ergonomic workloads would differ between robotic and laparoscopic surgeries and whether any ergonomic differences would be related to surgeons' robotic surgery skill level. Our hypothesis is that the unique features in robotic surgery will demonstrate skill-related results both in substantially less physical and cognitive workload and uncompromised task performance. Thirteen MIS surgeons were recruited for this institutional review board-approved study and divided into three groups based on their robotic surgery experiences: laparoscopy experts with no robotic experience, novices with no or little robotic experience, and robotic experts. Each participant performed six surgical training tasks using traditional laparoscopy and robotic surgery. Physical workload was assessed by using surface electromyography from eight muscles (biceps, triceps, deltoid, trapezius, flexor carpi ulnaris, extensor digitorum, thenar compartment, and erector spinae). Mental workload assessment was conducted using the NASA-TLX. The cumulative muscular workload (CMW) from the biceps and the flexor carpi ulnaris with robotic surgery was significantly lower than with laparoscopy (p < 0.05). Interestingly, the CMW from the trapezius was significantly higher with robotic surgery than with laparoscopy (p < 0.05), but this difference was only observed in laparoscopic experts (LEs) and robotic surgery novices. NASA-TLX analysis showed that both robotic surgery novices and experts expressed lower global workloads with robotic surgery than with laparoscopy, whereas LEs showed higher global workload with robotic surgery (p > 0.05). Robotic surgery experts and novices had significantly higher performance scores with robotic surgery than with laparoscopy (p < 0.05). This study demonstrated that the physical and cognitive ergonomics with robotic surgery were significantly less challenging. Additionally, several ergonomic components were skill-related. Robotic experts could benefit the most from the ergonomic advantages in robotic surgery. These results emphasize the need for well-structured training and well-defined ergonomics guidelines to maximize the benefits utilizing the robotic surgery.

Two studies are presented that examine the influence of media messages about cosmetic surgery on youths' interest in altering their own physical appearance. In Study 1, 170 participants (59% female; M age=19.77 years) completed surveys assessing their impression of reality television shows featuring cosmetic surgery, appearance satisfaction, self-esteem, and their interest in cosmetic surgery. Results indicated that participants who reported favorable impressions of reality television shows featuring cosmetic surgery were more likely to indicate interest in pursuing surgery. One hundred and eighty-nine participants (51% female; M age=19.84 years) completed Study 2. Approximately half of the participants were exposed to a television message featuring a surgical make-over; the other half was exposed to a neutral message. Results indicated that participants who watched a television program about cosmetic surgery wanted to alter their own appearance using cosmetic surgery more than did participants who were not exposed to this program.

Acute kidney injury (AKI) has been increasingly recognized as a common and serious postoperative complication. Although many studies have been conducted to investigate postoperative AKI after thoracic surgery, little is known about AKI after esophageal surgery. Thus, we conducted this study to determine the incidence and identify risk factors of postoperative AKI after esophageal cancer surgery. A retrospective nested case-control study of patients undergoing elective esophageal cancer surgery between July 2013 and July 2016 in a single tertiary specialized cancer hospital was performed. The primary outcome was development of AKI. Conditional logistic regression analysis was performed to identify independent risk factors for AKI. Of 2094 patients, 51 (2.4%) developed postoperative AKI after esophageal cancer surgery. In multivariate conditional logistic regression analysis, four risk factors for AKI after esophageal surgery for cancer were identified: preoperative serum creatinine level (OR 1.040; 95% CI 1.012-1.069), duration of surgery (OR 1.009; 95% CI 1.005-1.014), smoking history (OR 3.029; 95% CI 1.092-8.399) and hypertension (OR 6.422; 95% CI 2.736-15.070). Postoperative AKI occurred in 2.4% of patients after esophageal surgery for cancer. Preoperative serum creatinine level, duration of surgery, smoking history and hypertension were independent risk factors for postoperative AKI. Copyright © 2017 IJS Publishing Group Ltd.

Aesthetic surgery and Google: ubiquitous, unregulated and enticing websites for patients considering cosmetic surgery.

Rufai, Sohaib R; Davis, Christopher R

2014-05-01

Patient safety is a fundamental issue in aesthetic surgery. In an attempt to improve safety, the Department of Health (DoH) and Professor Sir Bruce Keogh published a review in 2013 of the regulation of cosmetic interventions. Proposals included: (1) Banning free consultations; (2) Restricting time-limited promotional deals; (3) Two-stage written pre-operative consent; (4) Consultations with a medical professional rather than a sales 'consultant'. The Cosmetic Surgical Practice Working Party (CSWP) recommended a two week "cooling off" period before surgery. This study quantified compliance with the above national initiatives by aesthetic surgery providers in the UK. To replicate a patient searching for aesthetic surgery providers, "cosmetic surgery UK" was searched via Google. The top fifty websites of aesthetic surgery providers were included in the study. Websites were analysed for compliance with the DoH Keogh and CSWP recommendations. When clarification was required, aesthetic surgery providers were contacted via telephone. Pearson's Chi-squared test compared actual compliance with national recommendations of full compliance. Fifty cosmetic surgery providers in the UK entered the study. Consultations with the operating surgeon occurred in 90% of cases. Mean compliance with all parameters from the national guidelines was 41%, significantly less than the desired level of full compliance (P < 0.001). The majority offered free consultations (54%) and promotional deals (52%), of which 27% were time limited. No provider stipulated compliance with two stages of signed consent. This study demonstrated low compliance with national guidelines for aesthetic surgery. Aggressive sales techniques and enticing offers by aesthetic surgery providers were widespread. Statutory government guidelines on aesthetic surgery and increased public awareness into potential risks from inappropriate cosmetic surgery may improve patient decision making and safety.

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.

Predictors of cosmetic surgery and its effects on psychological factors and mental health: a population-based follow-up study among Norwegian females.

There is limited information about psychological predictors of cosmetic surgery and how cosmetic surgery influences subsequent changes in mental health and overall appearance satisfaction. To date, there is a lack of studies examining this issue, whereby representative population samples are assessed at an age before cosmetic surgery is typically conducted and followed up after such surgery has commonly been performed. We obtained data from a survey study following 1597 adolescent females from a representative Norwegian sample over a 13-year period. Participants provided information on cosmetic surgery, appearance satisfaction, mental health, risky sexual behavior, drug use and conduct problems at two time-points (overall response rate 67%). Of all participants, 78 (4.9%) reported having undergone cosmetic surgery, of whom 71 were operated on during the course of the study and seven before the first data collection. Symptoms of depression and anxiety [odds ratio (OR) 1.66, 95% confidence interval (CI) 1.07-2.57] and a history of deliberate self-harm (OR 2.88, 95% CI 1.46-5.68), parasuicide (OR 3.29, 95% CI 1.53-7.08) and illicit drug use (OR 2.46, 95% CI 1.07-5.82) predicted prospective cosmetic surgery. Moreover, those who underwent surgery during the course of the study experienced a greater increase than other females in symptoms of depression and anxiety (t=2.07, p=0.04) and eating problems (t=2.71, p<0.01). Patients' use of alcohol also increased more than among non-patients (t=2.47, p=0.01). A series of mental health symptoms predict cosmetic surgery. Cosmetic surgery does not in turn seem to alleviate such mental health problems.

No study has investigated preoperative anxiety about spinal surgery under general anesthesia. The purposes of this study were (1) to determine how many patients have preoperative anxiety about spinal surgery and general anesthesia, (2) to evaluate the level of anxiety, (3) to identify patient factors potentially associated with the level of anxiety, and (4) to describe the characteristics of the anxiety that patients experience during the perioperative period. This study was performed in 175 consecutive patients undergoing laminectomy for lumbar stenosis or discectomy for herniated nucleus pulposus under general anesthesia. Demographic data, information related to surgery, and characteristics of anxiety were obtained using a questionnaire. The level of anxiety was assessed using a visual analog scale of anxiety (VAS-anxiety). Patient factors potentially associated with the level of anxiety were investigated using multiple stepwise regression analysis. Of 157 patients finally included in this study, 137 (87%) had preoperative anxiety (VAS-anxiety > 0). The mean VAS-anxiety score for spinal surgery was significantly higher than that for general anesthesia (4.6 ± 3.0 vs. 3.2 ± 2.7; P < 0.001). Sex and age were significant patient factors related to the level of anxiety about spinal surgery (P = 0.009) and general anesthesia (P = 0.018); female patients had a higher level of anxiety about spinal surgery, and elderly patients had a higher level of anxiety about general anesthesia. The most helpful factors in overcoming anxiety before surgery and in reducing anxiety after surgery were faith in the medical staff (48.9 %) and surgeon's explanation of the surgery performed (72.3%), respectively. Patients awaiting laminectomy or discectomy feared spinal surgery more than general anesthesia. This study also found that medical staff and surgeons play important roles in overcoming and reducing patient anxiety during the perioperative period.

Fast-track surgery after gynaecological oncological surgery: study protocol for a prospective randomised controlled trial.

PubMed

Cui, Ling; Shi, Yu; Zhang, G N

2016-12-15

Fast-track surgery (FTS), also known as enhanced recovery after surgery, is a multidisciplinary approach to accelerate recovery, reduce complications, minimise hospital stay without increasing readmission rates, and reduce health care costs, all without compromising patient safety. The advantages of FTS in abdominal surgery most likely extend to gynaecological surgery, but this is an assumption, as FTS in elective gynaecological surgery has not been well studied. No consensus guidelines have been developed for gynaecological oncological surgery although surgeons have attempted to introduce slightly modified FTS programmes for patients undergoing such surgery. To our knowledge, there are no published randomised controlled trials; however, some studies have shown that FTS in gynaecological oncological surgery leads to early hospital discharge with high levels of patient satisfaction. The aim of this study is whether FTS reduces the length of stay in hospital compared to traditional management. The secondary aim is whether FTS is associated with any increase in post-surgical complications compared to traditional management (for both open and laparoscopic surgery). This trial will prospectively compare FTS and traditional management protocols. The primary endpoint is the length of post-operative hospitalisation (days, mean ± standard deviation), defined as the number of days between the date of discharge and the date of surgery. The secondary endpoints are complications in both groups (FTS versus traditional protocol) occurring during the first 3 months post-operatively including infection (wound infection, lung infection, intraperitoneal infection), post-operative nausea and vomiting, ileus, post-operative haemorrhage, post-operative thrombosis, and the Acute Physiology and Chronic Health Enquiry II score. The advantages of FTS most likely extend to gynaecology, although, to our knowledge, there are no randomised controlled trials. The aim of this study is to compare the post-operative length of hospitalisation after major gynaecological or gynaecological oncological surgery and to analyse patients' post-operative complications. This trial may reveal whether FTS leads to early hospital discharge with few complications after gynaecological surgery. NCT02687412 . Approval Number: SCCHEC20160001.

This study aims to investigate whether cosmetic surgery has an effect on an individual's body image, general self-esteem, and psychological problems. Further tests were conducted to assess whether the extent of psychological problems before surgery influenced improvements in postoperative psychological outcomes. Questionnaire data from 155 female cosmetic surgery patients from a plastic surgery clinic were obtained before and approximately 6 months after surgery. The questionnaire consisted of measures on body image, self-esteem, and psychological problems. Pre- and postoperative values were compared. Pre- and postoperative measures were also compared with the data compiled from a representative sample of 838 Norwegian women, aged 22-55, with no cosmetic surgery experience. No differences in psychological problems between the presurgery patient and comparison samples were found, whereas differences in body image and self-esteem between the sample groups were reported in an earlier publication. Analyses further revealed an improvement in body image (satisfaction with own appearance) after surgery. A significant but rather small effect on self-esteem was also found, whereas the level of psychological problems did not change after surgery. Postoperative measures of appearance satisfaction, self-esteem, and psychological problems did not differ from values derived from the comparison sample. Finally, few psychological problems before surgery predicted a greater improvement in appearance satisfaction and self-esteem after surgery. The study provides evidence of improvement in satisfaction with own appearance after cosmetic surgery, a variable that is thought to play a central role in understanding the psychology of cosmetic surgery patients. The study also points to the factors that surgeons should be aware of, particularly the role of psychological problems, which could inhibit the positive effects of cosmetic surgery.

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.

Abstract The development of new medical electronic devices and equipment has increased the use of electrical apparatuses in surgery. Many studies have reported the association of long-term exposure to extremely low-frequency magnetic fields (ELF-MFs) with diseases or cancer. Robotic surgery has emerged as an alternative tool to overcome the disadvantages of conventional laparoscopic surgery. However, there has been no report regarding how much ELF-MF surgeons are exposed to during laparoscopic and robotic surgeries. In this observational study, we aimed to measure and compare the ELF-MFs that surgeons are exposed to during laparoscopic and robotic surgery. The intensities of the ELF-MFs surgeons are exposed to were measured every 4 seconds for 20 cases of laparoscopic surgery and 20 cases of robotic surgery using portable ELF-MF measuring devices with logging capability. The mean ELF-MF exposures were 0.6 ± 0.1 mG for laparoscopic surgeries and 0.3 ± 0.0 mG for robotic surgeries (significantly lower with P < 0.001 by Mann–Whitney U test). Our results show that the ELF-MF exposure levels of surgeons in both robotic and conventional laparoscopic surgery were lower than 2 mG, which is the most stringent level considered safe in many studies. However, we should not overlook the effects of long-term ELF-MF exposure during many surgeries in the course of a surgeon's career. PMID:25674758

Sporadic Creutzfeldt-Jakob disease (sCJD) is potentially transmissible to humans. This study aimed to summarise and rate the quality of the evidence of the association between surgery and sCJD. Firstly, we conducted systematic reviews and meta-analyses of case-control studies with major surgical procedures as exposures under study. To assess quality of evidence, we used the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. Secondly, we conducted a systematic review of sCJD case reports after sharing neurosurgical instruments. Thirteen case-control studies met the inclusion criteria for the systematic review of case-control studies. sCJD was positively associated with heart surgery, heart and vascular surgery and eye surgery, negatively associated with tonsillectomy and appendectomy, and not associated with neurosurgery or unspecified major surgery. The overall quality of evidence was rated as very low. A single case-control study with a low risk of bias found a strong association between surgery conducted more than 20 years before disease onset and sCJD. Seven cases were described as potentially transmitted by reused neurosurgical instruments. The association between surgery and sCJD remains uncertain. Measures currently recommended for preventing sCJD transmission should be strongly maintained. Future studies should focus on the potential association between sCJD and surgery undergone a long time previously.

To study the incidence and implications of vocal fold paresis (VFP) following congenital neonatal cardiac surgery. Retrospective chart review. All neonates who underwent median sternotomy for cardiac surgery from May 2007 to May 2008 were evaluated. Flexible laryngoscopy was performed to evaluate vocal fold function after extubation. Swallow evaluation and a modified barium swallow study were performed prior to initiating oral feeding if the initial screening was abnormal. A total of 101 neonates underwent cardiac surgery during the study period. Ninety-four patients underwent a median sternotomy, and 76 of these were included in the study. Fifteen (19.7%) had vocal fold paresis (VFP) postoperatively. Almost 27% of the patients with aortic arch surgery had VFP while only 4.1% of the patients with nonaortic arch surgery developed VFP (P=0.02) Those patients who underwent aortic arch surgery weighed significantly less (P<0.01). All the patients with VFP had significant morbidity related to swallowing and nutrition (P=0.01) and required longer postsurgical hospitalization (P=0.02). The reported incidence of VFP following cardiac surgery via median sternotomy ranges between 1.7% and 67% depending on the type of surgery and the weight of the infant at the time of surgery. In our cohort, 19.7% had VFP. Surgery requiring aortic arch manipulation had a higher incidence of complications and required longer hospitalizations. These results may be used to improve informed consent and to manage postoperative expectations by identifying patients who are at higher risk for complications.

Objective Reconstructive surgery to improve psychological well-being is commonly offered to children with craniofacial conditions. Few studies have explored the challenges of reconstructive surgery beyond the physical risks: poor treatment outcomes, infection, brain damage, and death. This qualitative study aims to understand the psychological and social implications such interventions can have for individuals with craniofacial conditions. Design A total of 38 individuals between the ages of 12 and 61 with such craniofacial conditions as Sturge-Weber syndrome, Treacher Collins syndrome, Möbius syndrome, cleft lip and palate, Noonan syndrome, Crouzon syndrome, and amniotic band syndrome participated in semistructured video-recorded interviews. Participants were recruited at conferences, through study flyers, and by word of mouth. Descriptive, thematic analysis was used to identify themes related to reconstructive surgery. Results Dominant themes included undergoing surgery to reduce stigmatization, the psychological and social implications of the interventions, outcome satisfaction, parental involvement in decision making about surgery, and recommendations for parents considering surgery for their children with craniofacial conditions. Experiences with reconstructive surgery varied, with some participants expressing surgical benefits and others, disillusionment. Conclusions The range of participant attitudes and experiences reflect the complexity of reconstructive surgery. Pediatric health care teams involved in the care of children with craniofacial conditions play an important role in advising patients (and their parents) about existing treatment options. The psychological and social implications of reconstructive surgery should be relayed to help families weigh the risks and benefits of surgery in an informed and meaningful way. PMID:22315960

2012-06-01

There have been few attempts to identify classic papers within the hand surgery literature. This study used citation analysis to identify and characterize the top 50 highly cited hand surgery articles published in six peer-reviewed journals. The 50 most highly cited hand surgery articles were identified in the Journal of Bone and Joint Surgery (JBJS) American, JBJS British, Plastic and Reconstructive Surgery, Journal of Hand Surgery (JHS) American, JHS British/European, and Hand. Articles were evaluated for citations per year, surgical/anatomical topic, and type of study. Clinical studies were further sub-categorized by level of evidence. The distribution of topics was compared with all indexed hand surgery articles. The educational relevance was assessed via comparison with lists of "classic" papers. The most common subjects were distal radius fracture, carpal tunnel syndrome, and flexor tendon repair. There was moderate correlation between the distribution of these topics and all indexed hand surgery articles (rho = 0.71). There were 31 clinical studies, of which 16 were therapeutic, ten were prognostic, and five were diagnostic. These articles assessed the outcomes of an intervention, described an anatomical/functional observation, introduced an innovation, presented a discovery/classification, or validated a questionnaire. There were only three randomized trials. Using citations per year to control for the influence of time since publication, 36 articles were consistently highly cited. Twenty-three articles were on Stern's Selected Readings in Hand Surgery, considered important in education. The top 50 highly cited articles in hand surgery reflect the most common clinical, scientific, and educational efforts of the field.

Efficacy of tension-free vaginal tape compared with transobturator tape in the treatment of stress urinary incontinence in women: analysis of learning curve, perioperative changes of voiding function

PubMed Central

2011-01-01

Background In this study, by comparing TVT surgery and TOT surgery for stress urinary incontinence in women, the characteristics and learning curves of both operative methods were studied. Methods A total of 83 women with stress urinary incontinence treated with tension-free vaginal tape (TVT) (n = 38) or transobturator tape (TOT) (n = 45) at Saiseikai Central Hospital between April 2004 and September 2009 were included. We compare the outcomes and learning curves between TVT surgery and TOT surgery. In statistical analysis, Student's t test, Fisher's exact test, and Mann-Whitney's U test were used. Results The surgical durations were 37.4 ± 15.7 minutes with TVT surgery and 31.0 ± 8.3 minutes with TOT surgery. A longer period of time was required for TVT surgery (p = 0.025). The residual urine at post-operative day 1 was higher in TVT surgery (25.9 ± 44.2 ml) than in TOT surgery (10.6 ± 19.2 ml) (p = 0.0452). The surgical duration of TVT surgery was shortened after the operator had performed 15 operations (p = 0.019). Conclusions In comparison of TVT surgery and TOT surgery, the surgical duration of TVT surgery was longer and the residual urine of TVT surgery was higher at post-operative day 1. Surgical experience could shorten the duration of TVT surgery. PMID:21726448

Several recent studies have suggested that warming up prior to surgery may improve surgical performance. The purpose of this study was to investigate whether warming up prior to laparoscopic surgery improves surgical performance or reduces surgery duration. Between August 2011 and January 2012, a randomized controlled trial was conducted to compare two warm-up modalities to no warm-up. The study was conducted at a single site, with nine surgeons performing 72 laparoscopic cholecystectomies and 37 laparoscopic appendicectomies. Prior to surgery, surgeons were randomized to either laparoscopic trainer box warm-up, PlayStation 2 warm-up or no warm-up. The activity was performed within 30 min of surgery commencing. Patients provided informed consent for the surgery to be digitally recorded. Digital videodiscs (DVDs) were reviewed by an independent and blinded assessor. Data were collected on duration of surgery, level of training and perceived surgical difficulty. Surgical performance was graded using a validated scoring system. From the 109 operations performed, there were 75 usable DVDs. Overall, there were no statistical differences in the demographics of patients and surgeons in the three treatment groups, nor in the subset that had useable DVDs. There were no statistical differences in the duration of surgery or surgeon's perceived surgical difficulty. There was no statistical difference in surgical performance. This study suggests that warm-up prior to laparoscopic cholecystectomy or appendicectomy is not essential, acknowledging that there are several study limitations that preclude definitive conclusion. © 2012 The Authors.

To evaluate patient satisfaction and regret with their decision for reconstructive surgery, and determine if they valued each item equally in the composite definition of success after making the decision for surgery. A list was created including all patients who underwent laparoscopic sacral colpopexy or laparoscopic uterosacrocolpopexy. Patients were placed in mutually exclusive outcome categories (retreatment, symptomatic failure, anatomic failure, and surgical success). Retreatment included any postoperative treatment for urinary incontinence, pelvic organ prolapse including pessary use, or surgery for mesh complications. The validated modified Decision Regret Scale (DRS) and the Satisfaction Decision Scale (SDS) questionnaires were administered by telephone. Higher DRS scores indicate greater regret and higher SDS scores indicate greater satisfaction with the decision for surgery. Of 715 patients, 197 were successfully contacted by telephone following reconstructive surgery and surveyed as study participants. Composite surgical outcomes were available for 150. Information on the need for retreatment was available for all the study participants. Surgery was successful in 101 (67.3 %) of the study participants. Anatomic failure occurred in 14, symptomatic failure occurred in 10, and retreatment was required in 25 of the study participants. Overall, the study participants were more satisfied than regretful with their decision for reconstructive surgery. Regret and satisfaction with their decision differed between outcomes in the composite definition of success after reconstructive surgery. Surgeons and patients should focus on retreatment rates during preoperative outcome discussions because retreatment will result in the least satisfaction and greatest regret with the decision for reconstructive surgery.

Expediting rotator cuff surgery is expected to facilitate recovery and return to work in injured workers. This case-control study examined the effect of expedited rotator cuff surgery on recovery and work status in injured workers. Injured workers who had undergone an expedited rotator cuff surgery funded by parallel-pay insurance (study group) were compared with workers who had used the public health insurance (control group) while adjusting for sex, age, severity of pathology, and follow-up period. Disability was measured by the American Shoulder and Elbow Surgeons (ASES) Standardized Assessment Form score. The percentage of patients who exceeded the minimal clinically important difference of 17 points in the ASES was calculated. The study group waited less time to have surgery than the control group (P < .0001), reported less disability after surgery, and had a higher number of patients whose improvement exceeded the minimal clinically important difference (119 vs. 65, P < .0001). The study group was more likely to be working at the time of the final follow-up (P < .0001). The final multivariable regressions, which adjusted for unmatched variables, such as dominant side involvement, mechanism of injury, and associated operations that were different between groups, were consistent with univariable analyses indicating superior results in the study group. Injured workers who underwent expedited rotator cuff surgery reported less disability and had a more successful return to work after surgery than injured workers who waited longer for specialist assessment and surgery within the public health system.

Study Design Prospective population-based cohort study Objective To identify early predictors of lumbar spine surgery within 3 years after occupational back injury Summary of Background Data Back injuries are the most prevalent occupational injury in the United States. Little is known about predictors of lumbar spine surgery following occupational back injury. Methods Using Disability Risk Identification Study Cohort (D-RISC) data, we examined the early predictors of lumbar spine surgery within 3 years among Washington State workers with new worker’s compensation temporary total disability claims for back injuries. Baseline measures included worker-reported measures obtained approximately 3 weeks after claim submission. We used medical bill data to determine whether participants underwent surgery, covered by the claim, within 3 years. Baseline predictors (P < 0.10) of surgery in bivariate analyses were included in a multivariate logistic regression model predicting lumbar spine surgery. The model’s area under the receiver operating characteristic curve (AUC) was used to determine the model’s ability to identify correctly workers who underwent surgery. Results In the D-RISC sample of 1,885 workers, 174 (9.2%) had a lumbar spine surgery within 3 years. Baseline variables associated with surgery (P < 0.05) in the multivariate model included higher Roland Disability Questionnaire scores, greater injury severity, and surgeon as first provider seen for the injury. Reduced odds of surgery were observed for those under age 35, women, Hispanics, and those whose first provider was a chiropractor. 42.7% of workers who first saw a surgeon had surgery, in contrast to only 1.5% of those who saw a chiropractor. The multivariate model’s AUC was 0.93 (95% CI 0.92–0.95), indicating excellent ability to discriminate between workers who would versus would not have surgery. Conclusion Baseline variables in multiple domains predicted lumbar spine surgery. There was a very strong association between surgery and first provider seen for the injury, even after adjustment for other important variables. PMID:23238486

Limited evidence-based, interactive, Internet-delivered preoperative preparation programs for children and their parents exist. The purpose of this investigation was to develop and examine the effectiveness of the Internet-delivered, preoperative program (I-PPP) in alleviating prepoperative anxiety in children undergoing outpatient surgery. In Study 1, the I-PPP was developed and then evaluated by parent/child dyads and health care professionals. In Study 2, the effectiveness of I-PPP was examined. This study was a development and effectiveness study. For Study 1, participants were recruited from the community. For Study 2, participants were recruited from the Royal University Hospital. In Study 1, participants were 9 parent/child dyads and 5 health care professionals. In Study 2, participants were 32 children (3-7years) scheduled for outpatient surgery and one parent for each child. In Study 1, I-PPP modules were created and parent/child dyads and health care professionals evaluated I-PPP modules and treatment credibility. In Study 2, child patients and their parents completed the I-PPP prior to day of surgery. Observer-rated anxiety of child participants was measured during the day surgery experience. Parent state anxiety was measured prior to completing I-PPP, pre- and post-surgery. Post-surgery parents provided comments regarding the I-PPP. Post-surgery child behaviour change was assessed. For Study 1, ratings for I-PPP components and treatment credibility surpassed our acceptability criterion. Minor changes were made to I-PPP. For Study 2, mYPAS scores were stable across day surgery. mYPAS scores in current study at induction did not differ significantly from benchmark studies. Significant reduction in parent anxiety was observed pre- to post-surgery. Parents positively endorsed the program. Negative post-operative behaviours were observed in a proportion of children. Our findings suggest that I-PPP represents a viable option for preoperative preparation for children and their parents. Crown Copyright © 2017. Published by Elsevier Inc. All rights reserved.

The role of 3-D printing is presented for improved patient-specific surgery planning. Key benefits are time saved and surgery outcome. Two hard-tissue surgery models were 3-D printed, for orthopedic, pelvic surgery, and craniofacial surgery. We discuss software data conversion in computed tomography (CT)/magnetic resonance (MR) medical image for 3-D printing. 3-D printed models save time in surgery planning and help visualize complex pre-operative anatomy. Time saved in surgery planning can be as much as two thirds. In addition to improved surgery accuracy, 3-D printing presents opportunity in materials research. Other hard-tissue and soft-tissue cases in maxillofacial, abdominal, thoracic, cardiac, orthodontics, and neurosurgery are considered. We recommend using 3-D printing as standard protocol for surgery planning and for teaching surgery practices. A quick turnaround time of a 3-D printed surgery model, in improved accuracy in surgery planning, is helpful for the surgery team. It is recommended that these costs be within 20 % of the total surgery budget.

Endoscopic transsphenoidal surgery has been shown to be a safe and effective treatment option for patients with pituitary tumours, but no study has explored patients' perceptions before and after this surgery. The authors in this study aim to explore patients' perceptions on endoscopic transsphenoidal surgery. Using qualitative research methodology, two semi-structured interviews were conducted with 30 participants who were adults aged > 18 undergoing endoscopic transsphenoidal surgery for the resection of a pituitary tumour between December 2008 and June 2011. The interviews were audiotaped and transcribed. The resulting data was analyzed using a modified thematic analysis. Seven overarching themes were identified: (1) Patients had a positive surgical experience; (2) patients were satisfied with the results of the procedure; (3) patients were initially surprised that neurosurgery could be performed endonasally; (4) patients expected a cure and to feel better after the surgery; (5) many patients feared that something might go wrong during the surgery; (6) patients were psychologically prepared for the surgery; (7) most patients reported receiving adequate pre-op and post-op information. This is the first qualitative study reporting on patients' perceptions before and after an endoscopic endonasal transsphenoidal pituitary surgery, which is increasingly used as a standard surgical approach for patients with pituitary tumours. Patients report a positive perception and general satisfaction with the endoscopic transsphenoidal surgical experience. However, there is still room for improvement in post-surgical care. Overall, patients' perceptions can help improve the delivery of comprehensive care to future patients undergoing pituitary tumour surgery.

Familial adenomatous polyposis (FAP) is a genetic disorder. Some female patients with FAP can become pregnant. However, the current state of childbirth after surgery for FAP is unclear in Japan. The study investigated 303 patients (147 female) who had undergone surgery for FAP at the 23 institutions between 2000 and 2012. Eighty female patients had information available on childbirth after surgery for FAP. Eight patients (10 %) gave birth after surgery. The mean age at surgery for FAP was 27 (range 20-41) years and 37 years in patients with and without childbirth after surgery, respectively (P = 0.044). The rate of childbirth after surgery was 17 % in women ≤30 years of age and 13 % in those ≤40 years of age. Although only one patient with invasive cancer (2.9 %) gave childbirth after surgery, seven patients without cancer (15.6 %) gave birth (P = 0.045). This study clarified the current state of childbirth after surgery for FAP in Japan. It is important to use these data to determine the best therapeutic approach for female FAP patients.

Robotic Colorectal Surgery

Robotic colorectal surgery has gradually been performed more with the help of the technological advantages of the da Vinci® system. Advanced technological advantages of the da Vinci® system compared with standard laparoscopic colorectal surgery have been reported. These are a stable camera platform, three-dimensional imaging, excellent ergonomics, tremor elimination, ambidextrous capability, motion scaling, and instruments with multiple degrees of freedom. However, despite these technological advantages, most studies did not report the clinical advantages of robotic colorectal surgery compared to standard laparoscopic colorectal surgery. Only one study recently implies the real benefits of robotic rectal cancer surgery. The purpose of this review article is to outline the early concerns of robotic colorectal surgery using the da Vinci® system, to present early clinical outcomes from the most current series, and to discuss not only the safety and the feasibility but also the real benefits of robotic colorectal surgery. Moreover, this article will comment on the possible future clinical advantages and limitations of the da Vinci® system in robotic colorectal surgery. PMID:19108010

To assess safety of topical anesthesia for transpupillary silicone oil removal in combination with cataract surgery. Department of Ophthalmology Mannheim, University of Heidelberg, Mannheim, Germany. The clinical interventional study included 37 consecutive patients having transpupillary silicone oil removal combined with cataract surgery. Without exception, surgery was carried out in topical anesthesia for all patients. During the study period, there were no patients having transpupillary silicone oil removal in another type of local anesthesia than topical anesthesia. Topical anesthesia was achieved with oxybuprocaine 0.4% eyedrops installed 4 to 5 times prior to surgery. Cataract surgery was performed using the clear cornea technique with implantation of a foldable intraocular posterior chamber lens. Silicone oil was released through a planned posterior capsulotomy during cataract surgery prior to implantation of the intraocular lens (IOL). For all patients, surgery could be carried out in topical anesthesia without switching to peribulbar or any other type of anesthesia. None of the patients complained about severe pain intraoperatively or postoperatively. No severe complications such as expulsive hemorrhage, luxation of the IOL, or iris incarceration were encountered in any of the surgeries. Transpupillary silicone oil through a planned posterior capsulotomy during cataract surgery may be performed in topical surgery.

Unnecessary surgery.

The extent of unnecessary surgery has been the object of considerable speculation and occasional wild accusation in recent years. Most evidence of the existence of unnecessary surgery, such as information from studies of geographic variations and the results of second surgical opinion programs, is circumstantial. However, results from the few studies that have measured unnecessary surgery directly indicate that for some highly controversial operations the fraction that are unwarranted could be as high as 30 percent. Most unnecessary surgery results from physician uncertainty about the effectiveness of an operation. Elimination of this uncertainty requires more efficient production and dissemination of scientific information about clinical effectiveness. In the absence of adequate data from scientific studies, the use of a consensus of expert opinion, disseminated by means of comprehensive practice guidelines, offers the best opportunity to identify and eliminate unnecessary surgery.

The purpose of this study was to perform a systematic review and meta-analysis of complications after orthognathic surgery comparing piezo-surgery with conventional osteotomy. We conducted this study according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We performed a systematic search of PubMed, Scopus, Science Direct, Lilacs, Cochrane Central Register of Controlled Trials, Google Scholar, and OpenThesis to identify randomized and nonrandomized controlled trials (RCTs and nRCTs, respectively) comparing patient outcomes (operative time, intraoperative blood loss, postoperative swelling, pain, neurosensitivity) after orthognathic surgery by piezoelectric or conventional osteotomy. We pooled individual results of continuous and dichotomous outcome data using the mean difference (MD) and risk difference (RD) with the 95% confidence interval, respectively. Three RCTs and five nRCTs were selected. No difference in operative time was observed between piezo-surgery and conventional osteotomies. We found a decrease of intraoperative blood loss with piezo-surgery (MD -128 mL; P < 0.001) and a pooled difference in severe blood loss of 35% (P = 0.008) favouring piezo-surgery. Based on pooled individual results of studies evaluating neurosensitivity by clinical neurosensory testing, our meta-analysis showed a pooled difference in severe nerve disturbance of 25% (P < 0.0001) favouring piezo-surgery. Test for subgroup differences (I2 = 26.6%) indicated that follow-up time may have an effect on neurosensory disturbance. We found differences between piezo-surgery and conventional osteotomy at 3 months (RD 28%; P < 0.001) and 6 months (RD 15%; P = 0.001) after surgery. Meta-analyses for pain and swelling were not performed because of a lack of sufficient studies. Currently available evidence suggests that piezo-surgery has favorable effects on complications associated with orthognathic surgery, including reductions in intraoperative blood loss and severe nerve disturbance.

Quality of life among patients undergoing bariatric surgery: associations with mental health- A 1 year follow-up study of bariatric surgery patients

PubMed Central

2011-01-01

Background Preoperative mental health seems to have useful predictive value for Health Related Quality of Life (HRQOL) after bariatric surgery. The aim of the present study was to assess pre- and postoperative psychiatric disorders and their associations with pre- and postoperative HRQOL. Method Data were assessed before (n = 127) and one year after surgery (n = 87). Psychiatric disorders were assessed by Mini International Neuropsychiatric Interview (M.I.N.I.) and Structured Clinical Interview (SCID-II). HRQOL was assessed by the Short Form 36 (SF-36) questionnaire. Results Significant improvements were found in HRQOL from preoperative assessment to follow-up one year after surgery. For the total study population, the degree of improvement was statistically significant (p values < .001) for seven of the eight SF-36 subscales from preoperative assessment to follow-up one year after surgery. Patients without psychiatric disorders had no impairments in postoperative HRQOL, and patients with psychiatric disorders that resolved after surgery had small impairments on two of the eight SF-36 subscales compared to the population norm (all effect sizes < .5) at follow-up one year after surgery. Patients with psychiatric disorders that persisted after surgery had impaired HRQOL at follow-up one year after surgery compared to the population norm, with effect sizes for the differences from moderate to large (all effect sizes ≥ .6). Conclusion This study reports the novel finding that patients without postoperative psychiatric disorders achieved a HRQOL comparable to the general population one year after bariatric surgery; while patients with postoperative psychiatric disorders did not reach the HRQOL level of the general population. Our results support monitoring patients with psychiatric disorders persisting after surgery for suboptimal improvements in quality of life after bariatric surgery.

Patients and animals with diabetes exhibit enhanced vulnerability to bacterial surgical infections. Despite multiple retrospective studies demonstrating the benefits associated with glycemic control in reducing bacterial infection after cardiac surgery, there are fewer guidelines on the use of glycemic control for noncardiac surgeries. In the current study, we investigated whether long-term (begun 2 weeks before surgery) or immediate (just before surgery) glycemic controls, continued postoperatively, can reduce surgical site infection in type 1 diabetic-induced rats. Rats were injected with streptozotocin to induce type 1 diabetes. Four groups of animals underwent surgery and thigh muscle Staphylococcus aureus bacteria challenge (1 × 10 colony forming units) at the time of surgery. Group 1 diabetic rats received insulin treatment just before surgery and continued until the end of study (short-term glycemic control group). Group 2 diabetic rats received insulin treatment 2 weeks before surgery and continued until the end of study (long-term glycemic control). Group 3 diabetic rats received no insulin treatment (no glycemic control group). Group 4 nondiabetic rats served as a healthy control group. Rats were euthanized at 3 or 6 days after surgery. Blood glucose and muscle bacterial burden were measured at 3 or 6 days after surgery. Glycemic control was achieved in both long- and short-term insulin-treated diabetic rats. Compared with untreated diabetic rats, the bacterial burden in muscle was significantly lower in both groups of glycemic controlled diabetic rats at 3 (all P < 0.003) and 6 (all P < 0.0001) days after surgery. A short-term glycemic control regimen, initiated just before surgery and bacterial exposure, was as effective in reducing surgical site infection as a long-term glycemic control in type 1 diabetic rats. These data suggest that immediately implementing glycemic control in type 1 diabetic surgical patients before undergoing noncardiac surgery may decrease the risk of infection.

Complications within laparoscopic surgery, similar to classic surgery are inevitable and require immediate actions both to diminish intraoperative risks and to choose the appropriate therapeutic attitude. Peritonitis and hemorrhagic incidents are both part of the complications aspect of laparoscopic surgery. Fortunately, the incidence is limited, thus excluding the rejection of celioscopic methods. Patient's risks and benefits are to be analyzed carefully prior recommending laparoscopic surgery. This study presents a statistical analysis of peritonitis consecutive to laparoscopic surgery, experience of "Sf. Ioan" Emergency Hospital, Bucharest, and Department of Surgery (2000-2010). There were 180 (0,96%) complicated situations requiring reinterventions, from a total of 18676 laparoscopic procedures. 106 cases (0,56%) represented different grades of postoperative peritonitis. Most frequently, there were consecutive laparoscopic appendicectomia and colecistectomia. During the last decade, few severe cases of peritonitis followed laparoscopic bariatric surgical procedures. This study reflects the possibility of unfavorable evolution of postoperative peritonitis comparing with hemorrhagic incidents within laparoscopic surgery.

The authors sought to review the various types of patients with psychological abnormalities who may present to the plastic surgeon and the psychological impact of various plastic surgery procedures on these patients. After systematically searching the Embase and PubMed databases and following further refinement (based on the authors' inclusion and exclusion criteria), the authors identified 65 studies. In addition, the authors felt that important information was contained in four textbooks, two press releases, and one Internet database. The inclusion criteria were studies that investigated the psychological outcomes, background, and personality types of patients seeking specific plastic surgery procedures. In addition, studies that addressed the impact of plastic surgery on patients' psychological status and quality of life were also included. The authors excluded studies with fewer than 30 patients, studies that did not pertain to the particular plastic surgery procedures, and studies that addressed psychological sequelae of revision operations. Narcissistic and histrionic personality disorders and body dysmorphic disorder are the three most common psychiatric conditions encountered in patients seeking cosmetic surgery. Overall, plastic surgery not only restores the appearance and function of the disfigured body unit but also alleviates psychological distress. Identifying the psychologically challenging patient before surgical intervention will allow the patient to obtain the appropriate psychological assistance and may result in a healthier individual with or without associated plastic surgery procedures.

Previous research shows an association between obesity and attention deficit hyperactivity disorder (ADHD). The present study compares pre- and post-bariatric surgery patients using the internationally used Conners' Adult ADHD Rating Scale (CAARS™) to screen for ADHD. Matched samples pre- (N = 120) and post-bariatric surgery (N = 128) were compared using self-rating instruments to assess ADHD-relevant symptomatology, depression, eating-related psychopathology, and BMI. Prevalence of probable ADHD did not differ between groups using the CAARS Index Scale T-scores; however, CAARS subscales Inattention/Memory and Self-Concept showed significantly lower scores in post-surgery patients. All CAARS subscales correlated significantly with each other, with depression and eating-related psychopathology. There was no correlation between ADHD and excess BMI loss in post-surgery patients. The findings suggest that a considerable number of patients before and after bariatric surgery screened positive for ADHD. It can be hypothesized that some core ADHD symptoms improve after surgery. Future studies are warranted to investigate the influence of ADHD on long-term surgery outcomes. © 2017 The Author(s) Published by S. Karger GmbH, Freiburg.

Increased postoperative mortality in low volume centers has contributed to merge and space thoracic surgical centers. Some studies have showed that the likelihood of receiving surgery was lower in lung cancer patients living far from a thoracic surgery center. Our objective was thus to determine whether surgery and survival rates in patients with non-small-cell lung cancer (NSCLC) were influenced by the distance between the respiratory and thoracic surgery departments. KBP-2010-CPHG is a prospective multicenter epidemiological study including 6083 patients followed in 104 nonacademic hospitals for primary NSCLC diagnosed in 2010. Distance between respiratory and thoracic surgery departments were obtained retrospectively. Predictive factors for surgery and mortality were identified by logistic regression and Cox hazard model. Twenty-three percent of hospitals had a thoracic surgery department; otherwise, mean distance between the hospital and the surgery center was 65km. Nineteen percent of patients underwent surgery. Distance was neither an independent factor for surgery (odds-ratios [95% CI]: 0.971 [0.74-1.274], 0.883 [0.662-1.178], and 1.015 [0.783-1.317] for 1-34, 35-79, and ≥80km vs. 0km) nor for mortality (hazard-ratios [95% CI]: 1.020 [0.935-1.111], 1.003 [0.915-1.099], and 1.006 [0.927-1.091]) (P>0.05). This result supports the French national strategy which merges surgery departments and should reassure patients (and physicians) who could be afraid to be lately addressed to surgery or loose chance when being followed far from the thoracic surgical center.

The Society of Gynecologic Surgeons Systematic Review Group performed a systematic review of both randomized and observational studies to compare robotic vs nonrobotic surgical approaches (laparoscopic, abdominal, and vaginal) for treatment of both benign and malignant gynecologic indications to compare surgical and patient-centered outcomes, costs, and adverse events associated with the various surgical approaches. MEDLINE and the Cochrane Central Register of Controlled Trials were searched from inception to May 15, 2012, for English-language studies with terms related to robotic surgery and gynecology. Studies of any design that included at least 30 women who had undergone robotic-assisted laparoscopic gynecologic surgery were included for review. The literature yielded 1213 citations, of which 97 full-text articles were reviewed. Forty-four studies (30 comparative and 14 noncomparative) met eligibility criteria. Study data were extracted into structured electronic forms and reconciled by a second, independent reviewer. Our analysis revealed that, compared with open surgery, robotic surgery consistently confers shorter hospital stay. The proficiency plateau seems to be lower for robotic surgery than for conventional laparoscopy. Of the various gynecologic applications, there seems to be evidence that renders robotic techniques advantageous over traditional open surgery for management of endometrial cancer. However, insofar as superiority, conflicting data are obtained when comparing robotics vs laparoscopic techniques. Therefore, the specific method of minimally invasive surgery, whether conventional laparoscopy or robotic surgery, should be tailored to patient selection, surgeon ability, and equipment availability.

Maxillary surgery to correct dentofacial deformity has been practiced for almost 100 years. Significant advances have made maxillary surgery a safe and efficient means of correcting midface deformities. Anesthetic techniques, specifically hypotensive anesthesia, have allowed for safer working conditions. Landmark studies have proven manipulation and segmentalization of the maxilla is safe and allowed this surgery to become a mainstay in corrective jaw surgery. This article provides an overview of surgical techniques and considerations as they pertain to maxillary surgery for orthognathic surgery. Segmental surgery, openbite closure, vertical excess, grafting, and a technology update are discussed. Copyright © 2014 Elsevier Inc. All rights reserved.

The purpose of the present study was to compare the perioperative and oncologic outcomes between laparoscopic surgery and open surgery for transverse colon cancer. We conducted a retrospective review of patients who underwent surgery for transverse colon cancer at six Hallym University-affiliated hospitals between January 2005 and June 2015. The perioperative outcomes and oncologic outcomes were compared between laparoscopic and open surgery. Of 226 patients with transverse colon cancer, 103 underwent laparoscopic surgery and 123 underwent open surgery. There were no differences in the patient characteristics between the two groups. Regarding perioperative outcomes, the operation time was significantly longer in the laparoscopic group than in the open group (267.3 vs 172.7 minutes, P<0.001), but the time to soft food intake (6.0 vs 6.6 days, P=0.036) and the postoperative hospital stay (13.7 vs 15.7 days, P=0.018) were shorter in the laparoscopic group. The number of harvested lymph nodes was lower in the laparoscopic group than in the open group (20.3 vs 24.3, P<0.001). The 5-year overall survival (90.8% vs 88.6%, P=0.540) and disease-free survival (86.1% vs 78.9%, P=0.201) rates were similar in both groups. The present study showed that laparoscopic surgery is associated with several perioperative benefits and similar oncologic outcomes to open surgery for the resection of transverse colon cancer. Therefore, laparoscopic surgery offers a safe alternative to open surgery in patients with transverse colon cancer.

Gender dysphoria is a mismatch between a person's biological sex and gender identity. The best treatment is believed to be hormonal therapy and gender-confirming surgery that will transition the individual toward the desired gender. Treatment in Denmark is covered by public health care, and gender-confirming surgery in Denmark is centralized at a single-center with few specialized plastic surgeons conducting top surgery (mastectomy or breast augmentation) and bottom surgery (vaginoplasty or phalloplasty and metoidioplasty). To report the first nationwide single-center review on transsexual patients in Denmark undergoing gender-confirming surgery performed by a single surgical team and to assess whether age at time of gender-confirming surgery decreased during a 20-year period. Electronic patient databases were used to identify patients diagnosed with gender identity disorders from January 1994 through March 2015. Patients were excluded from the study if they were pseudohermaphrodites or if their gender was not reported. Gender distribution, age trends, and surgeries performed for Danish patients who underwent gender-confirming surgery. One hundred fifty-eight patients referred for gender-confirming surgery were included. Fifty-five cases (35%) were male-to-female (MtF) and 103 (65%) were female-to-male (FtM). In total, 126 gender-confirming surgeries were performed. For FtM cases, top surgery (mastectomy) was conducted in 62 patients and bottom surgery (phalloplasty and metoidioplasty) was conducted in 17 patients. For MtF cases, 45 underwent bottom surgery (vaginoplasty), 2 of whom received breast augmentation. The FtM:MtF ratio of the referred patients was 1.9:1. The median age at the time of surgery decreased from 40 to 27 years during the 20-year period. Gender-confirming surgery was performed on 65 FtM and 40 MtF cases at our hospital, and 21 transsexuals underwent surgery abroad. Mastectomy was performed in 62 FtM and bottom surgery in 17 FtM cases. Vaginoplasty was performed in 45 MtF and breast augmentation in 2 MtF cases. There was a significant decrease in age at the time of gender-confirming surgery during the course of the study period. Copyright © 2016 International Society for Sexual Medicine.

The primary objective of this study was to determine significant predictors of length of stay (LOS) beyond the first postoperative day after urogynecological surgery. A single-center retrospective cohort study was conducted in 2015. Our study population included women who underwent inpatient pelvic reconstructive surgery. The primary outcome was LOS beyond the first postoperative day. A logistic regression analysis explored the relationship between 11 selected predictor variables [age, body mass index (BMI), American Society of Anesthesiologists (ASA) score, distance from home to hospital, length of surgery, anesthesia during surgery, route of surgical approach, trial of void recordings, choice of bladder protocol, presence of concomitant sling, surgeon], and LOS. Two hundred and sixty-three patients were included in this study. A logistic regression analysis identified route of surgery and trial of void recordings as the two statistically significant predictors of stay beyond the first postoperative day. The odds of LOS after laparoscopic or open surgery compared with vaginal surgery increased more than fivefold [laparoscopic vs. vaginal approach odds ratio (OR) 5.04, 95 % confidence interval (CI) 1.95-13.03; laparotomy vs. vaginal OR 15.56, 95 % CI 1.77-136.77] and more than threefold for a prolonged pass of the bladder protocol compared with an immediate pass (OR 3.25, 95 % CI 1.54-6.87). Our study identified route of surgery and trial of void recordings as the two predictors with the greatest impact on LOS beyond the first postoperative day. Our results warrant a larger follow-up study.

Patient risk perceptions for carotid endarterectomy: which patients are strongly averse to surgery?

Patient risk perception for surgery may be central to their willingness to undergo surgery. This study examined potential factors associated with patient aversion of surgery. This is a secondary data analysis of a prospective cohort study that examined patients referred for evaluation of carotid artery stenosis at five Veterans Affairs Medical Centers. The study collected demographic, clinical, and psychosocial information related to surgery. This analysis focused on patient response to a question assessing their aversion to surgery. Among the 1065 individuals, at the time of evaluation for carotid endarterectomy (CEA), 66% of patients had no symptoms, 16% had a transient ischemic attack, and 18% had stroke. Twelve percent of patients referred for CEA evaluation were averse to surgery. In adjusted analyses, increased age, black race, no previous surgery, lower level of chance locus of control, less trust of physicians, and less social support were significantly related to greater likelihood of surgery aversion among individuals referred for CEA evaluation. Patient degree of medical comorbidity and a validated measure of preoperative risk score were not associated with increased aversion to surgery. In previous work, aversion to CEA was associated with lack of receipt of CEA even after accounting for patient clinical appropriateness for surgery. We identified important patient characteristics associated with aversion to CEA. Interventions designed to assist patient decision making should focus on these more complex factors related to CEA aversion rather than the simple explanation of clinical usefulness.

[Mood disorders and epilepsy surgery: A review].

Yrondi, A; Arbus, C; Valton, L; Schmitt, L

2017-04-01

Historically, there is a strong link between depression and epilepsy. Patients with epilepsy are four to five times more likely to develop a depressive syndrome. It seems that the link between epilepsy and depression is bidirectional. There is little data on mood disorders secondary to epilepsy surgery. The goal of epilepsy surgery is to reduce the number and frequency of attacks, which in turn would allow improvements in mood disorders and cognitive impairment. A systematic search of the international literature was performed using the bibliographic search engines PubMed and Embase. The following MESH terms were used: epilepsy surgery AND (depression OR depressive disorder OR mood disorder). We also used the "related articles" of PubMed, bibliography surveys, conference abstracts and Google Scholar to identify additional relevant papers. Of the 130 studies found by the systematic search, 112 are excluded because they did not take into account the mood disorders secondary to epilepsy surgery. Fifteen studies are included in this review of the literature with a case study. Depression is the psychopathological condition that is the most frequently studied. According to several studies, the prevalence of depression is approximately 30% with nearly 70% of cases diagnosed during the first three months following epilepsy surgery. The majority of patients presented depressive symptoms during the first 3 to 12months after epilepsy surgery. In these studies, the risk of developing depression is correlated with the existence of previous depressive elements relative to the epilepsy surgery. A small number of studies reported cases of de novo depression. Studies have shown a correlation between very good to excellent control of epileptic seizures and a persistent improvement of mood disorders. It would seem that depressive symptoms post-surgery are more common when the surgical intervention concerns the temporal lobe and in particular mesial resections. There are only very few cases of maniac episodes. Hamid et al. showed an increased risk of suicide waning after the epilepsy surgery over a period of 5years. Mood disorders are common psychiatric comorbidities in epilepsy surgery. The detection, prevention, and treatment of these symptoms in patients eligible for epilepsy surgery pose major challenges for psychiatrists and neurologists, requiring their close collaboration.

What is the role of enhanced recovery after surgery in children? A scoping review.

PubMed

Pearson, Katherine L; Hall, Nigel J

2017-01-01

Enhanced recovery after surgery (ERAS) pathways are standard practice in adult specialties resulting in improved outcomes. It is unclear whether ERAS principles are applicable to Paediatric Surgery. We performed a scoping review to identify the extent to which ERAS has been used in Paediatric Surgery, the nature of interventions, and outcomes. Pubmed, Cochrane library, Google Scholar, and Embase were searched using the terms enhanced recovery, post-operative protocol/pathway, fast track surgery, and paediatric surgery. Studies were excluded if they did not include abdominal/thoracic/urological procedures in children. Nine studies were identified (2003-2014; total 1269 patients): three case control studies, one retrospective review and five prospective implementations, no RCTs. Interventional elements identified were post-operative feeding, mobilisation protocols, morphine-sparing analgesia, reduced use of nasogastric tubes and urinary catheters. Outcomes reported included post-operative length of stay (LOS), time to oral feeding and stooling, complications, and parent satisfaction. Fast-track programmes significantly reduced LOS in 6/7 studies, time to oral feeding in 3/3 studies, and time to stooling in 2/3 studies. The use of ERAS pathways in Paediatric surgery appears very limited but such pathways may have benefits in children. Prospective studies should evaluate interventions used in adult ERAS on appropriate outcomes in the paediatric setting.

Robot-assisted laparoscopic surgery is being performed more frequently for the minimally invasive management of rectal cancer. The objective of this meta-analysis was to compare the clinical and oncologic safety and efficacy of robot-assisted versus conventional laparoscopic surgery. A search of the Medline and Embase databases was performed for studies that compared clinical or oncologic outcomes of conventional laparoscopic proctectomy with robot-assisted laparoscopic proctectomy for rectal cancer. The methodological quality of the selected studies was critically assessed to identify studies suitable for inclusion. Meta-analysis was performed by a random effects model and analyzed by Review Manager. Clinical outcomes evaluated were conversion rates, operation times, length of hospital stay, and complications. Oncologic outcomes evaluated were circumferential margin status, number of lymph nodes collected, and distal resection margin lengths. Eight comparative studies were assessed for quality, and seven studies were included in the meta-analysis. Two studies were matched case-control studies, and five were unmatched. A total of 353 robot-assisted laparoscopic surgery proctectomy cases and 401 conventional laparoscopic surgery proctectomy cases were analyzed. Robotic surgery was associated with a significantly lower conversion rate (P=0.03; 95% confidence interval 1-12). There was no difference in complications, circumferential margin involvement, distal resection margin, lymph node yield, or hospital stay (P=NS). Robot-assisted surgery decreased the conversion rate compared to conventional laparoscopic surgery. Other clinical outcomes and oncologic outcomes were equivalent. The benefits of robotic rectal cancer surgery may differ between population groups.

Kang, Min Jung; De Gagne, Jennie C; Kang, Hee Sun

2016-04-01

The aim of this study was to explore the work experience of perioperative nurses involved in robotic surgery. A qualitative descriptive study was conducted. Participants were 15 nurses who had been on a robotic surgery team at one of five major university hospitals in Seoul, South Korea. Participants were one male and 14 female nurses (mean age, 31.33 [SD, 4.19] years; range, 25-41 years). Their experience as robotic surgery nurses ranged from 8 months to 6 years. Nurses' experiences with robotic surgery were categorized within four main themes: (1) constant checking on patients' safety and the robot's functions; (2) unexpected robotic machine errors or malfunctions; (3) feelings of burden in a robotic surgical team; and (4) need and desire for more information and education. This study showed that there are common concerns about patient safety and the possibility of emergencies related to robot system failure among nurses. Offering more support for nurses involved in robotic surgery should be a priority to empower them to play an extended role in robotic surgery.

Barriers to Cataract Surgery in Africa: A Systematic Review.

Aboobaker, Shaheer; Courtright, Paul

2016-01-01

Cataract remains the leading cause of blindness in Africa. We performed a systematic literature search of articles reporting barriers to cataract surgery in Africa. PubMed and Google Scholar databases were searched with the terms "barriers, cataract, Africa, cataract surgery, cataract surgical coverage (CSC), and rapid assessment of avoidable blindness (RAAB)." The review covered from 1999 to 2014. In RAAB studies, barriers related to awareness and access were more commonly reported than acceptance. Other type of studies reported cost as the most common barrier. Some qualitative studies tended to report community and family dynamics as barriers to cataract surgery. CSC was lower in females in 88.2% of the studies. The variability in outcomes of studies of barriers to cataract surgery could be due to context and the type of data collection. It is likely that qualitative data will provide a deeper understanding of the complex social, family, community, financial and gender issues relating to barriers to uptake of cataract surgery in Africa.

Robotic surgery has become increasingly used due to its enhancement of visualization, precision, and articulation. It eliminates many of the problems encountered with conventional minimally invasive techniques and has been shown to result in reduced blood loss and complications. The rise in endoscopic procedures in otolaryngology-head and neck surgery, and associated difficulties, suggests that robotic surgery may have a role to play. To determine whether robotic surgery conveys any benefits compared to conventional minimally invasive approaches, specifically looking at precision, operative time, and visualization. A systematic review of the literature with a defined search strategy. Searches of MEDLINE, EMBASE and CENTRAL using strategy: ((robot* OR (robot*AND surgery)) AND (ent OR otolaryngology)) to November 2010. Articles reviewed by authors and data compiled in tables for analysis. There were 33 references included in the study. Access and visualization were regularly mentioned as key benefits, though no objective data has been recorded in any study. Once initial setup difficulties were overcome, operative time was shown to decrease with robotic surgery, except in one controlled series of thyroid surgeries. Precision was also highlighted as an advantage, particularly in otological and skull base surgery. Postoperative outcomes were considered equivalent to or better than conventional surgery. Cost was the biggest drawback. The evidence base to date suggests there are benefits to robotic surgery in OHNS, particularly with regards to access, precision, and operative time but there is a lack of controlled, prospective studies with objective outcome measures. In addition, economic feasibility studies must be carried out before a robotic OHNS service is established. Copyright © 2012 Elsevier Inc. All rights reserved.

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.

The relationship between coronary artery bypass graft (CABG) surgery and cognitive decline remains uncertain, in particular with regard to whether there is delayed cognitive decline associated with this procedure. This was a population-based cohort study involving participants in the Cache County Study of Memory Health and Aging. At baseline the study enrolled 5,092 persons age 65 and older and followed them up three years later and again four years after that. Individuals who reported having undergone CABG surgery at study baseline or had this surgery in between follow-up waves were compared to individuals who never reported having the surgery. The main outcome measure was the Modified Mini Mental State (3MS). Multilevel models were used to examine the relationship between CABG surgery and cognitive decline over time. Study participants who had CABG surgery evidenced 0.95 points of greater decline relative to baseline on the 3MS at the first follow-up interview after CABG, and an average of 1.9 points of greater decline at the second follow-up interview, than those without CABG (t = -2.51, df = 2,316, p = 0.0121), after adjusting for several covariates, including number of vascular conditions. This decline was restricted to individuals who were more than five years past the procedure and was not evident in the early years after the surgery. CABG surgery is associated with accelerated cognitive decline more than five years after the procedure in a long-lived population. This decline is small and its clinical significance is uncertain. We could not find an association between CABG and decline in the first five post-operative years.

Background. Several characteristics appear to be important for estimating the likelihood of reentering the workforce after surgery. The aim of the present study was to describe work status in a two-year time period around the time of cardiac surgery and estimate the probability of returning to the workforce. Methods. We included 681 patients undergoing coronary artery bypass grafting and/or heart valve procedures from 2003 to 2007 in the North Denmark Region. We linked hospital data to data in the DREAM database which holds information of everyone receiving social benefits. Results. At the time of surgery 17.3% were allocated disability pension and 2.3% were allocated a permanent part-time benefit. Being unemployed one year before surgery reduced the likelihood of return to the workforce (RR = 0.74 (0.60-0.92)) whereas unemployment at the time of surgery had no impact on return to the workforce (RR = 0.96 (0.78-1.18)). Sickness absence before surgery reduced the likelihood of return to the workforce. Conclusion. This study found the work status before surgery to be associated with the likelihood of return to the workforce within one year after surgery. Before surgery one-fifth of the population either was allocated disability pension or received a permanent part-time benefit.

Bone Metabolism after Bariatric Surgery

PubMed Central

Yu, Elaine W.

2014-01-01

Bariatric surgery is a popular and effective treatment for severe obesity, but may have negative effects on the skeleton. This review summarizes changes in bone density and bone metabolism from animal and clinical studies of bariatric surgery, with specific attention to Roux-en-Y gastric bypass (RYGB), adjustable gastric banding (AGB), and sleeve gastrectomy (SG). Skeletal imaging artifacts from obesity and weight loss are also considered. Despite challenges in bone density imaging, the preponderance of evidence suggests that bariatric surgery procedures have negative skeletal effects that persist beyond the first year of surgery, and that these effects vary by surgical type. The long-term clinical implications and current clinical recommendations are presented. Further study is required to determine mechanisms of bone loss after bariatric surgery. Although early studies focused on calcium/vitamin D metabolism and mechanical unloading of the skeleton, it seems likely that surgically-induced changes in the hormonal and metabolic profile may be responsible for the skeletal phenotypes observed after bariatric surgery.

The purpose of this review was to analyse and report criteria used for open and arthroscopic surgical treatment of femoroacetabular impingement syndrome (FAIS). A librarian-assisted computer search of Medline, CINAHL and Embase for studies related to criterion for FAIS surgery was used in this study. Inclusion criteria included studies with the primary purpose of surgery or surgical outcomes for treatment of FAIS with and without labral tear, and reporting criteria for FAIS surgery. Diagnostic imaging was a criterion for surgery in 92% of the included studies, with alpha angle the most frequently reported (68% of studies) criterion. Reporting of symptoms was a criterion for surgery in 75%, and special tests a criterion in 70% of studies. Range-of-motion limitations were only a required criterion in 30%, only 12% of studies required intra-articular injection and 44% of studies described previously failed treatment (non-surgical or physiotherapist-led rehabilitation) as a criterion for surgery. Only 56% of included studies utilised the combination of symptoms, clinical signs and diagnostic imaging combined for diagnosis of FAIS as suggested by the Warwick Agreement on FAIS meeting. Diagnostic imaging evidence of FAIS was the most commonly reported criterion for surgery. Only 56% of included studies utilised the combination of symptoms, clinical signs and diagnostic imaging for diagnosis of FAIS as suggested by the Warwick Agreement on FAIS meeting, and only 44% of studies had failed non-surgical treatment (and 18% a failed trial of physiotherapy) as a criterion for surgery. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Background Psychological symptoms are highly prevalent in patients with shoulder complaints. Psychological symptoms in patients with shoulder complaints might play a role in the aetiology, perceived disability and pain and clinical outcome of treatment. The aim of this study was to assess whether preoperative symptoms of distress, depression, anxiety and somatisation were associated with a change in function after shoulder surgery and postoperative patient perceived improvement of pain and function. In addition, the change of psychological symptoms after shoulder surgery was analyzed and the influence of postoperative symptoms of psychological disorders after surgery on the change in function after shoulder surgery and perceived postoperative improvement of pain and function. Methods and Findings A prospective longitudinal cohort study was performed in a general teaching hospital. 315 consecutive patients planned for elective shoulder surgery were included. Outcome measures included change of Disabilities of the Arm, Shoulder and Hand (DASH) score and anchor questions about improvement in pain and function after surgery. Psychological symptoms were identified before and 12 months after surgery with the validated Four-Dimensional Symptom Questionnaire (4DSQ). Psychological symptoms were encountered in all the various shoulder diagnoses. Preoperative symptoms of psychological disorders persisted after surgery in 56% of patients, 10% of patients with no symptoms of psychological disorders before surgery developed new psychological symptoms. Preoperative symptoms of psychological disorders were not associated with the change of DASH score and perceived improvement of pain and function after shoulder surgery. Patients with symptoms of psychological disorders after surgery were less likely to improve on the DASH score. Postoperative symptoms of distress and depression were associated with worse perceived improvement of pain. Postoperative symptoms of distress, depression and somatisation were associated with worse perceived improvement of function. Conclusions Preoperative symptoms of distress, depression, anxiety and somatisation were not associated with worse clinical outcome 12 months after shoulder surgery. Symptoms of psychological disorders before shoulder surgery persisted in 56% of patients after surgery. Postoperative symptoms of psychological disorders 12 months after shoulder surgery were strongly associated with worse clinical outcome. PMID:27846296

With rising prevalence of morbid obesity, the number of bariatric surgeries performed each year has been increasing worldwide. The objective of this meta-analysis was to assess the risk of kidney stones following bariatric surgery. A literature search was performed using MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews from inception through July 2015. Only studies reporting relative risks, odd ratios or hazard ratios (HRs) to compare risk of kidney stones in patients who underwent bariatric surgery versus no surgery were included. Pooled risk ratios (RR) and 95% confidence interval (CI) were calculated using a random-effect, generic inverse variance method. Four studies (One randomized controlled trial and three cohort studies) with 11,348 patients were included in analysis to assess the risk of kidney stones following bariatric surgery. The pooled RR of kidney stones in patients undergoing bariatric surgery was 1.22 (95% CI, 0.63-2.35). The type of bariatric surgery subgroup analysis demonstrated an increased risk of kidney stones in patients following Roux-en-Y gastric bypass (RYGB) with the pooled RR of 1.73 (95% CI, 1.30-2.30) and a decreased risk of kidney stones in patients following restrictive procedures including laparoscopic banding or sleeve gastrectomy with the pooled RR of 0.37 (95% CI, 0.16-0.85). Our meta-analysis demonstrates an association between RYGB and increased risk of kidney stones. Restrictive bariatric surgery, on the other hand, may decrease kidney stone risk. Future study with long-term follow-up data is needed to confirm this potential benefit of restrictive bariatric surgery.

The purpose of orthognathic surgery is to correct facial deformity and dental malocclusion and to obtain normal orofacial function. However, there are controversies of whether orthognathic surgery might have any negative influence on temporomandibular (TM) joint. The purpose of this study was to evaluate the influence of orthognathic surgery on articular disc position and temporomandibular joint symptoms of skeletal CI II patients by means of magnetic resonance imaging. For this purpose, fifteen patients with skeletal CI II malocclusion, aged 19-32 years (mean 23 years), 10 women and 5 men, from the Isfahan Department of Oral and Maxillofacial Surgery were studied. All received LeFort I and bilateral sagittal split osteotomy (BSSO) osteotomies and all patients received pre- and post-surgical orthodontic treatment. Magnetic resonance imaging was performed 1 day preoperatively and 3 month postoperatively. Descriptive statistics and Wilcoxon and Mc-Nemar tests were used for statistical analysis. P <0.05 was considered significant. Disc position ranged between 4.25 and 8.09 prior to surgery (mean=5.74±1.21). After surgery disc position range was 4.36 to 7.40 (mean=5.65±1.06). Statistical analysis proved that although TM disc tended to move anteriorly after BSSO surgery, this difference was not statistically significant ( p value<0.05). The findings of the present study revealed that orthognathic surgery does not alter the disc and condyle relationship. Therefore, it has minimal effects on intact and functional TM joint. Key words: Orthognathic surgery, skeletal class 2, magnetic resonance imaging, temporomandibular disc.

The Effectiveness of Nurse-Led Preoperative Assessment Clinics for Patients Receiving Elective Orthopaedic Surgery: A Systematic Review.

PubMed

Sau-Man Conny, Chan; Wan-Yim, Ip

2016-12-01

Nurse-led preoperative assessment clinics (POAC) have been introduced in different specialty areas to assess and prepare patients preoperatively in order to avoid last-minute surgery cancellations. Not all patients are referred to POACs before surgery, and the benefits of nurse-led POACs are not well documented in Hong Kong. The purpose of this systemic review was to identify the best available research evidence to inform current clinical practice, guide health care decision making and promote better care. The Joanna Briggs Institute (JBI) approach for conducting systematic review of quantitative research was used. Data bases searched included all published and unpublished studies in Chinese and English. All studies with adult patients who required elective orthopaedic surgery e.g. total knee replacement, total hip replacement, reduction of fracture or reconstruction surgery etc. in a hospital or day surgery center and attended a nurse-led POAC before surgery were included. Ten studies were critically appraised. Results showed that nurse-led POACs can reduce surgery cancellation rates. These studies suggested a reduction in the rate of postoperative mortality and length of hospital stay. In addition, the level of satisfaction towards services provided was significantly high. Although POACs are being increasingly implemented worldwide, the development of clinical guidelines, pathways and protocols was advocated. The best available evidence asserted that nurses in the POAC could serve as effective coordinators, assessors and educators. The nurse-led practice optimized patients' condition before surgery and hence minimized elective surgery cancellations. Copyright © 2016 American Society of PeriAnesthesia Nurses.

Background: Problems regarding bowel elimination are quite common in patients undergoing abdominal surgery. Objectives: To determine constipation risk before the surgery, bowel elimination during postoperative period, and the factors affecting bowel elimination. Patients and Methods: This is a cross-sectional study. It was conducted in a general surgery ward of a university hospital in Zonguldak, Turkey between January 2013 and May 2013. A total of 107 patients were included in the study, who were selected by convenience sampling. Constipation Risk Assessment Scale (CRAS), patient information form, medical and nursing records were used in the study. Results: The mean age of the patients was found to be 55.97 ± 15.74 (year). Most of the patients have undergone colon (37.4%) and stomach surgeries (21.5%). Open surgical intervention (83.2%) was performed on almost all patients (96.3%) under general anesthesia. Patients were at moderate risk for constipation with average scores of 11.71 before the surgery. A total of 77 patients (72%) did not have bowel elimination problem during postoperative period. The type of the surgery (P < 0.05), starting time for oral feeding after the surgery (P < 0.05), and mobilization (P < 0.05) were effective on postoperative bowel elimination. Conclusions: There is a risk for constipation after abdominal surgery. Postoperative practices are effective on the risk of constipation. PMID:26380107

Many insurance companies have considerable prebariatric surgery requirements despite a lack of evidence for improved clinical outcomes. The hypothesis of this study is that insurance-specific requirements will be associated with a decreased progression to surgery and increased delay in time to surgery. Retrospective data collection was performed for patients undergoing bariatric surgery evaluation from 2010-2015. Patients who underwent surgery (SGY; n = 827; mean body mass index [BMI] 49.1) were compared with those who did not (no-SGY; n = 648; mean BMI: 49.4). Univariate and multivariate analysis were performed to identify specific co-morbidity and insurance specific predictors of surgical dropout and time to surgery. A total of 1475 patients using 12 major insurance payors were included. Univariate analysis found insurance requirements associated with surgical drop out included longer median diet duration (no-SGY = 6 mo; SGY = 3 mo; P<.001); primary care physician letter of necessity (P<.0001); laboratory testing (P = .019); and evaluation by cardiology (P<.001), pulmonology (P<.0001), or psychiatry (P = .0003). Using logistic regression to control for co-morbidities, longer diet requirement (odds ratio [OR] .88, P<.0001), primary care physician letter (OR .33, P<.0001), cardiology evaluation (OR .22, P = .038), and advanced laboratory testing (OR 5.75, P = .019) independently predicted surgery dropout. Additionally, surgical patients had an average interval between initial visit and surgery of 5.8±4.6 months with significant weight gain (2.1 kg, P<.0001). Many prebariatric surgery insurance requirements were associated with lack of patient progression to surgery in this study. In addition, delays in surgery were associated with preoperative weight gain. Although prospective and multicenter studies are needed, these findings have major policy implications suggesting insurance requirements may need to be reconsidered to improve medical care.

It was reported that lack of knowledge, less confidence of medical services, commute difficulties, and poor economic conditions would be the main barriers for cataract surgery practice. The influencing factors could have changed in cities with high developing speed. Shanghai is one of the biggest cities in China and the world. The purpose of the study was to explore the factors influencing cataract surgery practice in Shanghai. This was a population-based, cross-sectional study. A total of 2342 cataract patients older than 50 years old with cataract-induced visual impairment or who had undergone cataract surgery were recruited from rural and urban areas of Shanghai. Participants accepted a face-to-face structured questionnaire. Data were collected on patient demographics, education, work, income, health insurance, awareness about cataracts disease, treatment and related medical resources and deration policy, transportation and degree of satisfaction with hospitals. There were 417 patients who had received cataract surgery, 404 of them supplied complete information in the questionnaire. More female subjects (64.6%) than male subjects (35.4%) accepted cataract surgery among the 404 patients. Of the patients with cataract history, 36.4% of surgery patients were equal or older than 80. More people with urban medical insurance received surgery (p = 0.036). Patients who received surgery were more satisfied with local medical service (p = 0.032). In urban area, Lower income and difficulties with commutes were related to a higher rate of surgery. Cataract patients with the following features were more inclined to receive surgery: female, old age, better awareness. In urban areas low income and difficult commutes did not represent barriers for cataract surgery, probably because of appropriate cataract surgery promotion policies recent years in Shanghai. In rural areas, better healthcare reimbursement policies would likely lead to a higher uptake of cataract surgery. Further cohort studies with more controls could supply stronger evidence for our viewpoint.

Since its introduction in 1997, robotic surgery has overcome many limitations, including setup costs and surgeon training. The use of robotics in general surgery remains unknown. This study evaluates robotic-assisted procedures in general surgery by comparing characteristics with its nonrobotic (laparoscopic and open) counterparts. Weighted Healthcare Cost and Utilization Project Nationwide Inpatient Sample data (2008, 2009) were used to identify the top 12 procedures for robotic general surgery. Robotic cases were identified by Current Procedural Terminology codes 17.41 and 17.42. Procedures were grouped: esophagogastric, colorectal, adrenalectomy, lysis of adhesion, and cholecystectomy. Analyses were descriptive, t tests, χ(2)s, and logistic regression. Charges and length of stay were adjusted for gender, age, race, payer, hospital bed size, hospital location, hospital region, median household income, Charlson score, and procedure type. There were 1,389,235 (97.4%) nonrobotic and 37,270 (2.6%) robotic cases. Robotic cases increased from 0.8 per cent (2008) to 4.3 per cent (2009, P < 0.001). In all subgroups, robotic surgery had significantly shorter lengths of stay (4.9 days) than open surgery (6.1 days) and lower charges (median $30,540) than laparoscopic ($34,537) and open ($46,704) surgery. Fewer complications were seen in robotic-assisted colorectal, adrenalectomy and lysis of adhesion; however, robotic cholecystectomy and esophagogastric procedures had higher complications than nonrobotic surgery (P < 0.05). Overall robotic surgery had a lower mortality rate (0.097%) than nonrobotic surgeries per 10,000 procedures (laparoscopic 0.48%, open 0.92%; P < 0.001). The cost of robotic surgery is generally considered a prohibitive factor. In the present study, when overall cost was considered, including length of stay, robotic surgery appeared to be cost-effective and as safe as nonrobotic surgery except in cholecystectomy and esophagogastric procedures. Further study is needed to fully understand the long-term implications of this new technology.

People with schizophrenia or bipolar disorder (BD) exhibit very high levels of obesity. Little is known about the potential benefits/risks of obesity surgery. We conducted a narrative review to summarize the available knowledge on bariatric surgery in people with schizophrenia or BD. A systematic search was conducted of major electronic databases from inception to October 2016 for studies investigating bariatric surgery among people with schizophrenia or BD. Data were presented in a narrative synthesis and future research strategies proposed. The electronic database searches identified 44 records. Eight studies (BD, n = 265; schizophrenia: n = 14) were included with a mean study length of 15.7 months (12-24). Seven found that bariatric surgery resulted in weight loss in those with psychiatric disorders with an excess weight loss ranging -31 to -70%. Six studies found that weight loss from bariatric surgery was similar in people with schizophrenia or BD versus controls. However, most of the studies limited their outcomes to only weight loss and did not measure whether obesity surgery affected the status and treatment of psychiatric symptoms. Although few adverse events were reported among patients with BD, data from two studies demonstrated no significant deterioration of psychiatric symptoms post-surgery in people with schizophrenia. Growing evidence suggests that bariatric surgery may improve short-term weight status among people with BD. However, given the paucity of studies for schizophrenia, and the lack of information on medium-to long-term results, future large-scale high-quality studies are required.

"Like a trip to McDonalds": a grounded theory study of patient experiences of day surgery.

The amount and complexity of (ambulatory) day surgery is rapidly expanding internationally. Nurses have a responsibility to provide quality care for day surgery patients. To do this they must understand all aspects of the patient experience. There is dearth of research into day surgery using a sociological frame of reference. The study investigated patients' experiences of day surgery using a sociological frame of reference. A qualitative study using the grounded theory approach was used. The study was based in two day surgery units in two urban public hospitals in the United Kingdom. 145 patients aged 18-70 years and 100 carers were purposely selected from the orthopaedic, ear nose and throat and general surgical lists. They were all English speaking and were of varied socio-economic background. The data was collected from 2004 to 2006. Semi-structured interviews were conducted on three occasions: before surgery, 48 h following surgery and one month following discharge. Permission was received from the Local Research Ethics Committee. Analysis of the data involved line-by-line analysis, compilation of key words and phrases (codes) and constant comparison of the codes until categories emerged. Patients liked day surgery and placed it within the wider societal context of efficiency and speed. Time was a major issue for them. They wished surgery, like all other aspects of their life to be a speedy process. They likened it to a McDonald's experience with its emphasis on speed, predictability and control. This study throws new light on patient experiences and offers an understanding of day surgery against a western culture which emphasises the importance of speed and efficiency. It is a popular choice for patients but at times it can be seen to be a mechanistic way of providing care. The implications for nurses to provide education and information to add to the quality of the patient experience are discussed. Copyright © 2010 Elsevier Ltd. All rights reserved.

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.

Context: The ability to return to elite pitching, performance, and clinical outcomes of shoulder surgery in elite baseball pitchers are not definitively established. Objective: To determine (1) the rate of return to sport (RTS) in elite pitchers following shoulder surgery, (2) postoperative clinical outcomes upon RTS, and (3) performance upon RTS and to compare RTS rates in different types of shoulder surgery. Data Sources: Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and checklist, Medline, SciVerse Scopus, SportDiscus, and Cochrane Central Register of Controlled Trials were searched. Study Selection: Levels I-IV evidence were eligible for inclusion if performance-based (eg, RTS) and/or clinical outcome–based reporting of outcomes were reported following surgical treatment of shoulder pathology in elite pitchers (major or minor league or collegiate). Data Extraction: Subject, shoulder, and pre- and postoperative performance-based variables of interest were extracted. All shoulder surgery types were potentially inclusive (eg, open, arthroscopic, rotator cuff, labrum, biceps, acromioclavicular joint, fracture). Study methodological quality was analyzed using the Modified Coleman Methodology Score (MCMS). Results: Six studies were analyzed (287 elite male pitchers [mean age, 27 years] who underwent shoulder surgery, with 99% on the dominant, throwing shoulder). MCMS was 38 (poor). Most pitchers were professional, with a mean career length of 6.58 years and postoperative clinical follow-up of 3.62 years. In 5 of 6 studies, multiple diagnoses were addressed concomitantly at surgery. Rate of RTS was 68% at mean 12 months following surgery. Twenty-two percent of Major League Baseball (MLB) pitchers never RTS in MLB. Overall performance did improve following surgery; however, this did not improve to pre-injury levels. Conclusion: In this systematic review, the rate of return to elite baseball pitching following surgery was established. Performance tended to decrease prior to surgery and gradually improve postoperatively, though not reaching pre-injury levels of pitching. Level of Evidence: IV (systematic review of studies level I-IV evidence), therapeutic. PMID:24459557

The complexity of body image following bariatric surgery: a systematic review of the literature.

Poor body image is common among individuals seeking bariatric surgery and is associated with adverse psychosocial sequelae. Following massive weight loss secondary to bariatric surgery, many individuals experience excess skin and associated concerns, leading to subsequent body contouring procedures. Little is known, however, about body image changes and associated features from pre-to post-bariatric surgery and subsequent body contouring. The objective of the present study was to conduct a comprehensive literature review of body image following bariatric surgery to help inform future clinical research and care. The articles for the current review were identified by searching PubMed and SCOPUS and references from relevant articles. A total of 60 articles examining body image post-bariatric surgery were identified, and 45 did not include body contouring surgery. Overall, there was great variation in standards of reporting sample characteristics and body image terms. When examining broad levels of body image dissatisfaction, the literature suggests general improvements in certain aspects of body image following bariatric surgery; however, few studies have systematically examined various body image domains from pre-to post-bariatric surgery and subsequent body contouring surgery. In conclusion, there is a paucity of research that examines the multidimensional elements of body image following bariatric surgery. © 2018 World Obesity Federation.

Child is an ideal patient for day care surgery. So more than 60% of paediatric surgery could benefit by ambulatory surgery. Preoperative visit may select patients for ambulatory surgery. Medical exam may lead to choose pre operative screening. The ideal ambulatory anesthesia is locoregional technic or inhalatory one. Tracheal intubation don't contre indicate ambulatory surgery. Recovery of mental abilities following general anesthesia has not the same significance as in adult. Many studies confirm the safety of paediatric outpatients anesthesia.

Residual sleepiness after continuous positive airway pressure (CPAP) is a critical problem in some patients with obstructive sleep apnea syndrome (OSAS). However, nasal surgery is likely to reduce daytime sleepiness and feelings of unrefreshed sleep. The aim of this study is to clarify the effects of nasal surgery and CPAP on daytime sleepiness. This is a retrospective and matched-case control study. The participants were consecutive 40 patients with OSAS who underwent nasal surgery (Surgery group) and 40 matched patients who were treated with CPAP (CPAP group). In the Surgery group, although the nasal surgery did not decrease either apnea or hypopnea, it improved oxygenation, the quality of sleep. In the CPAP Group, the CPAP treatment reduced apnea and hypopnea, and improved oxygenation, quality of sleep. The degree of relief from daytime sleepiness was different between the two groups. The improvement of Epworth Sleepiness Scale was more significant in the Surgery Group than those in the CPAP Group (Surgery from 11.0 to 5.1, CPAP from 10.0 to 6.2). These findings suggest that the results of the nasal surgery is more satisfactory for some patients with OSAS than CPAP on daytime sleepiness.

Bariatric surgery: a viable treatment option for patients with severe mental illness.

Although bariatric surgery has become a recognized treatment for obesity, its utility among patients with severe psychiatric disorders has not been extensively studied. A few studies have reported similar weight loss outcomes in these patients, but psychiatric status after bariatric surgery has been studied only minimally, and it is unknown if exacerbation of the mental illness affects weight loss. The aim of this study was to shed greater light on the issue of serious mental illness and bariatric surgery. Specifically, do patients with a diagnosis of schizophrenia, bipolar I, and bipolar II have poorer weight loss outcomes postbariatric surgery than the general bariatric surgery population? Also, do patients with these diagnoses experience an exacerbation of psychiatric symptoms after bariatric surgery, and if so, is the exacerbation of these disorders linked to poorer weight loss results? Midwest university medical center. A medical record review of approximately 1500 bariatric patients in a Midwest university medical center was conducted to identify those patients with diagnoses of schizophrenia, bipolar I, and bipolar II. Information was gathered on bariatric surgery outcomes and changes in psychiatric status postsurgery. Eighteen patients were identified as undergoing bariatric surgery and having a diagnosis of schizophrenia, bipolar I, or bipolar II. Weight loss in this group was significant and comparable to expected outcomes of absolute weight lost, changes in body mass index, and percentage excess weight loss for patients in the typical bariatric population. Postsurgery psychiatric status was known on 10 patients. All 10 patients experienced some exacerbation of psychiatric problems yet weight loss outcomes were still as expected. Bariatric surgery is a viable obesity treatment option for patients with schizophrenia, bipolar I, and bipolar II disorders. Symptom exacerbations occurred postsurgery, although it is not clear if these were due to the surgery or would have occurred in the normal course of the illness.

Long surgical wait times and limited hospital capacity are common obstacles to surgical care in many countries in Sub-Saharan Africa (SSA). Introducing ambulatory surgery might contribute to a solution to these problems. The purpose of this study was to evaluate the safety and feasibility of introducing ambulatory surgery into a pediatric hospital in SSA. This is a cross-sectional descriptive study that took place over 6 months. It includes all patients assigned to undergo ambulatory surgery in the Pediatric University Hospital in Ouagadougou, Burkina Faso. Eligibility criteria for the ambulatory surgery program included >1 year of age, American Society of Anesthesiologists (ASA) 1 status, surgery with a low risk of bleeding, lasting <90 minutes, and with an expectation of mild to moderate postoperative pain. The family had to live within 1 hour of the hospital and be available by telephone. During the study period, a total of 1250 patients underwent surgery, of whom 515 were elective cases; 115 of these met the criteria for ambulatory surgery; 103 patients, with an average age of 59.74 ± 41.57 months, actually underwent surgery. The principal indications for surgery were inguinal (62) and umbilical (47) hernias. All patients had general anesthesia with halothane. Sixty-five percent also received regional or local anesthesia consisting of caudal block in 79.23% or nerve block in 20.77%. The average duration of surgery was 33 ± 17.47 minutes. No intraoperative complications were noted. All the patients received acetaminophen and a nonsteroidal anti-inflammatory drug in the recovery room. Twelve (11.7%) patients had complications in recovery, principally nausea and vomiting. Eight (7.8%) patients were admitted to the hospital. No serious complications were associated with ambulatory surgery. Its introduction could possibly be a solution to improving pediatric surgical access in low-income countries.

The presence of obstructive sleep apnea (OSA) in ambulatory surgical patients causes significant perioperative concern; however, few data exist to guide clinicians' management decisions. The objective of this study was to measure changes in perioperative sleep parameters among an ambulatory surgery population. This study is a prospective, observational study of ambulatory patients undergoing orthopedic surgery on an extremity. Study subjects completed three unattended home sleep apnea tests: baseline before surgery, the first night after surgery (N1), and third night after surgery (N3). Anesthesia and surgical teams were blinded to study participation and patients received routine perioperative care. Two hundred three subjects were enrolled and 166 completed the baseline home sleep test. Sixty-six (40.0%) had OSA at baseline, 35 patients received a new diagnosis, and 31 patients had a previous diagnosis of OSA. Of those with a previous diagnosis, 20 (64.5%) were compliant with continuous positive airway pressure therapy. Respiratory event index and SpO 2 nadir did not significantly change postoperatively from baseline. Cumulative percentage of time oxygen saturation < 90% significantly increased N1 as compared to baseline for all patients except for those with moderate to severe OSA. Ambulatory surgery had minimal effect on sleep parameters and there was no increase in adverse events among patients with either treated or untreated OSA.

Purpose The purpose of the present study was to compare the perioperative and oncologic outcomes between laparoscopic surgery and open surgery for transverse colon cancer. Patients and methods We conducted a retrospective review of patients who underwent surgery for transverse colon cancer at six Hallym University-affiliated hospitals between January 2005 and June 2015. The perioperative outcomes and oncologic outcomes were compared between laparoscopic and open surgery. Results Of 226 patients with transverse colon cancer, 103 underwent laparoscopic surgery and 123 underwent open surgery. There were no differences in the patient characteristics between the two groups. Regarding perioperative outcomes, the operation time was significantly longer in the laparoscopic group than in the open group (267.3 vs 172.7 minutes, P<0.001), but the time to soft food intake (6.0 vs 6.6 days, P=0.036) and the postoperative hospital stay (13.7 vs 15.7 days, P=0.018) were shorter in the laparoscopic group. The number of harvested lymph nodes was lower in the laparoscopic group than in the open group (20.3 vs 24.3, P<0.001). The 5-year overall survival (90.8% vs 88.6%, P=0.540) and disease-free survival (86.1% vs 78.9%, P=0.201) rates were similar in both groups. Conclusion The present study showed that laparoscopic surgery is associated with several perioperative benefits and similar oncologic outcomes to open surgery for the resection of transverse colon cancer. Therefore, laparoscopic surgery offers a safe alternative to open surgery in patients with transverse colon cancer. PMID:27143915

To evaluate fertility outcomes in infertile women with severe endometriosis (The revised American Fertility Society classification [AFS] 3-4) and repeated IVF failures, who underwent surgery due to exacerbation of endometriosis-related symptoms. Retrospective cohort study. University hospital. All women who failed IVF treatment before surgery and who underwent laparoscopic surgery for severe endometriosis between January 2006 and December 2014. All patients were operated by highly skilled surgeons specializing in laparoscopic surgery for advanced endometriosis. Only patients with evidence of endometriosis in the pathology specimens were included in this study. Delivery rate after surgery. Seventy-eight women were included in the present study. All women were diagnosed with severe endometriosis during surgery (AFS 3-4) and all women had experienced failed IVF treatments before surgery. All women were symptomatic before their surgery. After surgical treatment 33 women (42.3%) delivered. Three women (9%) conceived spontaneously and all other women conceived after IVF treatment. Women who delivered were younger (32.5 [±4.1] years vs. 35.5 [±3.8] years), were less often diagnosed with diminished ovarian reserve before surgery (6% vs. 28.8%), and were more often diagnosed with normal uterine anatomy (by preoperative transvaginal ultrasound and during operation). In addition, performing salpingectomy during surgery was associated with a trend of improvement in delivery rates after surgery (70% in women who delivered vs. 51% in women who failed to deliver). Symptomatic women with severe endometriosis and repeated IVF implantation failures may benefit from extensive laparoscopic surgery when performed by an experienced multidisciplinary surgical team to improve IVF outcome.

AimsTo establish the impact of adult strabismus surgery on clinical and psychosocial well-being and determine who experiences the greatest benefit from surgery and how one could intervene to improve quality of life post-surgery.MethodsA longitudinal study, with measurements taken pre-surgery and at 3 and 6 months post-surgery. All participants completed the AS-20 a disease specific quality of life scale, along with measures of mood, strabismus and appearance-related beliefs and cognitions and perceived social support. Participants also underwent a full orthoptic assessment at their preoperative visit and again 3 months postoperatively. Clinical outcomes of surgery were classified as success, partial success or failure, using the largest angle of deviation, diplopia and requirement for further therapy.Results210 participants took part in the study. Strabismus surgery led to statistically significant improvements in psychosocial and functional quality of life. Those whose surgery was deemed a partial success did however experience a deterioration in quality of life. A combination of clinical variables, high expectations, and negative beliefs about the illness and appearance pre-surgery were significant predictors of change in quality of life from pre- to post-surgery.ConclusionsStrabismus surgery leads to significant improvements in quality of life up to 6 months postoperatively. There are however a group of patients who do not experience these benefits. A series of clinical and psychosocial factors have now been identified, which will enable clinicians to identify patients who may be vulnerable to poorer outcomes post-surgery and allow for the development of interventions to improve quality of life after surgery.

AIM To analyses the current literature regarding the urogenital functional outcomes of patients receiving robotic rectal cancer surgery. METHODS A comprehensive literature search of electronic databases was performed in October 2015. The following search terms were applied: “rectal cancer” or “colorectal cancer” and robot* or “da Vinci” and sexual or urolog* or urinary or erect* or ejaculat* or impot* or incontinence. All original studies examining the urological and/or sexual outcomes of male and/or female patients receiving robotic rectal cancer surgery were included. Reference lists of all retrieved articles were manually searched for further relevant articles. Abstracts were independently searched by two authors. RESULTS Fifteen original studies fulfilled the inclusion criteria. A total of 1338 patients were included; 818 received robotic, 498 laparoscopic and 22 open rectal cancer surgery. Only 726 (54%) patients had their urogenital function assessed via means of validated functional questionnaires. From the included studies, three found that robotic rectal cancer surgery leads to quicker recovery of male urological function and five of male sexual function as compared to laparoscopic surgery. It is unclear whether robotic surgery offers favourable urogenital outcomes in the long run for males. In female patients only two studies assessed urological and three sexual function independently to that of males. In these studies there was no difference identified between patients receiving robotic and laparoscopic rectal cancer surgery. However, in females the presented evidence was very limited making it impossible to draw any substantial conclusions. CONCLUSION There seems to be a trend towards earlier recovery of male urogenital function following robotic surgery. To evaluate this further, larger well designed studies are required.

For severely obese patients, bariatric surgery has been recommended as an effective therapy. The Bariataric Surgery and Education (BaSE) study aimed to assess the efficacy of a videoconferencing-based psychoeducational group intervention in patients after bariatric surgery. The BaSE study is a randomized, controlled multicenter clinical trial involving 117 patients undergoing bariatric surgery (mean preoperative body mass index [BMI] 49.9 kg/m(2), SD 6.4). Patients were enrolled between May 2009 and November 2012 and were randomly assigned to receive either conventional postsurgical visits or, in addition, a videoconferencing-based 1-year group program. Primary outcome measures were weight in kilograms, health-related quality of life (HRQOL), and general self-efficacy (GSE). Secondary outcome measures were depression symptoms and eating behavior. 94% of the patients completed the study. Mean weight loss for all patients was 45.9 kg (SD 16.4) 1 year after surgery (mean excess weight loss [EWL] 63%). Intention-to-treat analyses revealed no differences in weight loss, EWL, HRQOL, or self-efficacy between study groups at 1 year after surgery. However, patients with clinically significant depression symptoms (CSD) at baseline assigned to the intervention group (n = 29) had a significantly better HRQOL (P = .03), lower depression scores (P = .02), and a trend for a better EWL (.06) 1 year after surgery compared with the control group (n = 20). We could not prove the efficacy of the group program for the whole study sample. However, results indicate that the intervention is effective for the important subgroup of patients with CSD.

To the best of our knowledge, there have been no previous studies evaluating the correlation of the US economy and hand surgery volume. Therefore, in light of the current recession, our objective was to study our institution's hand surgery volume over the last 17 years in relation to the nation's economy. A retrospective analysis of our institution's hand surgery volume, as represented by our most common procedure (ie, carpal tunnel release), was performed between January 1992 and October 2008. Liposuction and breast augmentation volumes were chosen to serve as cosmetic plastic surgery comparison groups. Pearson correlation statistics were used to estimate the relationship between the surgical volume and the US economy, as represented by the 3 market indices (Dow Jones, NASDAQ, and S&P500). A combined total of 7884 hand surgery carpal tunnel release (open or endoscopic) patients were identified. There were 1927 (24%) and 5957 (76%) patients within the departments of plastic and orthopedic surgery, respectively. In the plastic surgery department, there was a strong negative (ie, inverse relationship) correlation between hand surgery volume and the economy (P < 0.001). In converse, the orthopedic department's hand surgery volume demonstrated a positive (ie, parallel) correlation (P < 0.001). The volumes of liposuction and breast augmentation also showed a positive correlation (P < 0.001). To our knowledge, we have demonstrated for the first time an inverse (ie, negative) correlation between hand surgery volumes performed by plastic surgeons in relation to the US economy, as represented by the 3 major market indices. In contrast, orthopedic hand surgery volume and cosmetic surgery show a parallel (ie, positive) correlation. This data suggests that plastic surgeons are increasing their cosmetic surgery-to-reconstructive/hand surgery ratio during strong economic times and vice versa during times of economic slowdown.

Bariatric surgery for morbid obesity results in massive weight loss and improvement of health and quality of life. A downside of the major weight loss is the excess of overstretched skin, which may influence the patient's quality of life by causing functional and aesthetic problems. The purpose of the current study was to evaluate the patient's quality of life long-term after body contouring following bariatric surgery. Quality of life was measured with the Obesity Psychosocial State Questionnaire in 33 post-bariatric surgery patients 7.2 years (range, 3.2 to 13.3 years) after body contouring surgery. Data were compared with previous assessments 4.1 years (range, 0.7 to 9.2 years) after body contouring surgery of the quality of life at that time and before body contouring surgery. Compared with appraisals of quality of life before body contouring surgery, a significant, mostly moderate to large, sustained improvement of quality of life was observed in post-bariatric surgery patients 7.2 years after body contouring surgery in six of the seven psychosocial domains. A small deterioration occurred between 4.1- and 7.2-year follow-up on two of the seven domains except for the domain efficacy toward eating, which showed a significant improvement. At 7-year follow-up, 18 patients (55 percent) were satisfied with the result of body contouring surgery. This study indicates a sustained quality-of-life improvement in post-bariatric surgery patients after body contouring surgery. This suggests the importance of including reconstructive surgery as a component in the multidisciplinary approach in the surgical treatment of morbid obesity. Therapeutic, IV.

Purpose. To review the postoperative seizure outcomes of patients that underwent surgery for epilepsy at King Faisal Specialist Hospital & Research Centre (KFSHRC). Methods. A descriptive retrospective study for 502 patients operated on for medically intractable epilepsy between 1998 and 2012. The surgical outcome was measured using the ILAE criteria. Results. The epilepsy surgery outcome for temporal lobe epilepsy surgery (ILAE classes 1, 2, and 3) at 12, 36, and 60 months is 79.6%, 74.2%, and 67%, respectively. The favorable 12- and 36-month outcomes for frontal lobe epilepsy surgery are 62% and 52%, respectively. For both parietal and occipital epilepsy lobe surgeries the 12- and 36-month outcomes are 67%. For multilobar epilepsy surgery, the 12- and 36-month outcomes are 65% and 50%, respectively. The 12- and 36-month outcomes for functional hemispherectomy epilepsy surgery are 64.2% and 63%, respectively. According to histopathology diagnosis, mesiotemporal sclerosis (MTS) and benign CNS tumors had the best favorable outcome after surgery at 1 year (77.27% and 84.3%, resp.,) and 3 years (76% and 75%, resp.,). The least favorable seizure-free outcome after 3 years occurred in cases with dual pathology (66.6%). Thirty-four epilepsy patients with normal magnetic resonance imaging (MRI) brain scans were surgically treated. The first- and third-year epilepsy surgery outcome of 17 temporal lobe surgeries were (53%) and (47%) seizure-free, respectively. The first- and third-year epilepsy surgery outcomes of 15 extratemporal epilepsy surgeries were (47%) and (33%) seizure-free. Conclusion. The best outcomes are achieved with temporal epilepsy surgery, mesial temporal sclerosis, and benign CNS tumor. The worst outcomes are from multilobar surgery, dual pathology, and normal MRI.

Usual retinal surgery (vitrectomy or surgery for retinal detachment) may require additional procedures to deal with complex cases, which increase time and resource use and delay access to treatment. We undertook this study to identify the proportion of primary retinal surgeries that required complex procedures and the associated causes. We carried out an observational, descriptive, cross-sectional, retrospective study. Patients with primary retinal surgery were evaluated (January 2007-December 2010). The proportion and 95% confidence intervals (CI) of preoperative diagnosis and cause of the disease requiring retinal surgery as well as the causes for complex retinal surgery were identified. Complex retinal surgery was defined as that requiring lens extraction, intraocular lens implantation, heavy perfluorocarbon liquids, silicone oil tamponade or intravitreal drugs, in addition to the usual surgical retinal procedure. The proportion of complex retinal surgeries was compared among preoperative diagnoses and among causes (χ(2), odds ratio [OR]). We studied 338 eyes. Mean age of subjects was 53.7 years, and there were 49% females. The most common diagnoses were vitreous hemorrhage (27.2%) and rhegmatogenous retinal detachment (24.6%). The most common cause was diabetes (50.6%); 273 eyes required complex surgery (80.8%, 95% CI: 76.6-85). The proportion did not differ among diagnoses but was higher in diabetic retinopathy (89%, p <0.001, OR 3.04, 95% CI: 1.63-5.7). Of the total sample, 80.8% of eyes required complex surgical procedures; diabetic retinopathy increased by 3-fold the probability of requiring these complex procedures. Early treatment of diabetic retinopathy may reduce the proportion of complex retinal surgery by 56%.

Background There is growing evidence that obesity is associated with poor neurocognitive outcome. Bariatric surgery is an effective intervention for morbid obesity and improves many comorbid medical conditions that are associated with cognitive dysfunction. The effects of bariatric surgery on cognition are unknown. Methods Prospective study total of 150 individuals (109 bariatric surgery patients enrolled in the Longitudinal Assessment of Bariatric Surgery (LABS) project and 41 obese controls that did not undergo surgery) completed cognitive evaluation at baseline and 12 week follow-up. Demographic, medical, and psychosocial information was also collected to elucidate possible mechanisms of change. Results Many bariatric surgery patients exhibited impaired performance on cognitive testing at baseline (range from 4.6%–23.9%). However, surgery patients were no more likely to exhibit decline on two or more cognitive tests at 12-week follow-up than obese controls [12.84% vs. 23.26%; χ2 (1) = 2.51, p = .11]. Group comparisons using repeated measures MANOVA showed surgery patients had improved memory performance at 12 week follow-up [λ = .86, F(4, 147) = 5.88, p<.001], whereas obese controls actually declined. Regression analyses showed surgery patients without hypertension had better short delay recall at 12 weeks than those that did [β = 0.31, p = .005], though other demographic and medical variables were largely unrelated to test performance. Conclusion The current results suggest that cognitive impairment is common in bariatric surgery patients, though these deficits may be at least partly reversible. Future studies are needed to clarify underlying mechanisms, particularly longitudinal studies employing neuroimaging and blood markers. PMID:21145295

Postoperative pneumonia is a common complication of surgery, and is associated with marked morbidity and mortality. Despite advances in surgical and anesthetic technique, it persists as a frequent postoperative complication. Many studies have aimed to assess its burden, as well as associated risk factors. However, this complication varies among the different surgical specialties, and there is a paucity of reports that comprehensively evaluate this complication. Therefore, the purpose of this study was to review the epidemiology and risk factors of postoperative pneumonia in the setting of: 1) general surgery; 2) cardiothoracic surgery; 3) orthopedic and spine surgery; and 4) head and neck surgery.

Robotic surgery offers many potential benefits for patients. While an increasing number of healthcare providers are purchasing surgical robots, there are reports that the technology is failing to be introduced into routine practice. Additionally, in robotic surgery, the surgeon is physically separated from the patient and the rest of the team, with the potential to negatively impact teamwork in the operating theatre. The aim of this study is to ascertain: how and under what circumstances robotic surgery is effectively introduced into routine practice; and how and under what circumstances robotic surgery impacts teamwork, communication and decision making, and subsequent patient outcomes. We will undertake a process evaluation alongside a randomised controlled trial comparing laparoscopic and robotic surgery for the curative treatment of rectal cancer. Realist evaluation provides an overall framework for the study. The study will be in three phases. In Phase I, grey literature will be reviewed to identify stakeholders' theories concerning how robotic surgery becomes embedded into surgical practice and its impacts. These theories will be refined and added to through interviews conducted across English hospitals that are using robotic surgery for rectal cancer resection with staff at different levels of the organisation, along with a review of documentation associated with the introduction of robotic surgery. In Phase II, a multi-site case study will be conducted across four English hospitals to test and refine the candidate theories. Data will be collected using multiple methods: the structured observation tool OTAS (Observational Teamwork Assessment for Surgery); video recordings of operations; ethnographic observation; and interviews. In Phase III, interviews will be conducted at the four case sites with staff representing a range of surgical disciplines, to assess the extent to which the results of Phase II are generalisable and to refine the resulting theories to reflect the experience of a broader range of surgical disciplines. The study will provide (i) guidance to healthcare organisations on factors likely to facilitate successful implementation and integration of robotic surgery, and (ii) guidance on how to ensure effective communication and teamwork when undertaking robotic surgery.

A few studies have compared the cardiac rehabilitation (CR) outcome between those who undergo conventional on-pump bypass surgery and off-pump surgery. We compared this outcome among the patients differentiated by the On-pump and off-pump surgical procedures about cardiovascular variables and psychological status. This longitudinal study recruited 318 and 102 consecutive patients who had undergone CABG (on-pump surgery, n = 318 and off-pump surgery, n = 102) and been referred to the CR clinic. The off-pump surgery patients had more improvement in their metabolic equivalents (METs) value. The physical and mental components of health-related quality of life (QOL) (based on SF-36 questionnaire) as well as depression-anxiety (based on Costello-Comrey Depression and Anxiety Scale) were notably improved in the two study groups after the CR program, while changes in the QOL components scores and also depression-anxiety score were not different between the off-pump and on-pump techniques. Regarding QOL and psychological status, there were no differences in the CR outcome between those who underwent off-pump bypass surgery and those who underwent on-pump surgery; nevertheless, the off-pump technique was superior to the on-pump method on METs improvement following CR.

In recent years, cosmetic surgery in Iran, which is provided almost entirely by the private sector, has gained popularity despite evidence of its potential risks. In most cases, cosmetic surgeries are done to increase self-satisfaction and self-esteem, thus seeking cosmetic surgery potentially shows an individual's psychological profile. Current evidence needs studies on the psychological profile of Asian cosmetic surgery patients. The present study investigates psychological profile and personality traits of people seeking cosmetic surgery in Iran. The present prospective observational study was conducted with a sample of 274 randomly selected persons seeking cosmetic surgery (rhinoplasty, blepharoplasty, face/jaw implant, mammoplasty, and liposuction). All participants completed the validated and reliable the Global Severity Index (GSI)-Symptom Checklist-90-Revised (SCL-90-R)-and the short Neuroticism-Extraversion-Openness Five-Factor Inventory (NEO-FFI). The prevalence rate of psychiatric problems based on the GSI cut-off point (>63) of SCL-90-R was about 51 %, and interpersonal sensitivity and psychosis were the highest and lowest endorsed syndromes among the subjects, respectively. Openness had the lowest mean score; agreeableness and extroversion had the highest mean. The current study shows that understanding and psychological evaluation prior to surgery is necessary and screening can reduce the number of unnecessary surgeries and may enhance satisfaction with surgical results.

Increasing experience with minimally invasive surgery and the development of new instruments has resulted in a tendency toward reducing the number of abdominal skin incisions. Retrospective and randomized prospective studies could show the feasibility of single-incision surgery without any increased risk to the patient. However, large prospective multicenter observational datasets do not currently exist. This prospective multicenter observational quality study will provide a relevant dataset reflecting the feasibility and safety of single-incision surgery. This study focuses on external validity, clinical relevance, and the patients' perspective. Accordingly, the single-incision multiport/single port laparoscopic abdominal surgery (SILAP) study will supplement the existing evidence, which does not currently allow evidence-based surgical decision making. The SILAP study is an international prospective multicenter observational quality study. Mortality, morbidity, complications during surgery, complications postoperatively, patient characteristics, and technical aspects will be monitored. We expect more than 100 surgical centers to participate with 5000 patients with abdominal single-incision surgery during the study period. Funding was obtained in 2012. Enrollment began on January 01, 2013, and will be completed on December 31, 2018. As of January 2016, 2119 patients have been included, 106 German centers are registered, and 27 centers are very active (>5 patients per year). This prospective multicenter observational quality study will provide a relevant dataset reflecting the feasibility and safety of single-incision surgery. An international enlargement and recruitment of centers outside of Germany is meaningful.

Systematic review. The aim of this study was to review the techniques, indications, and outcomes of minimally invasive surgery (MIS) and separation surgery with subsequent radiosurgery in the treatment of patients with metastatic spine disease. The utilization of MIS techniques in patients with spine metastases is a growing area within spinal oncology. Separation surgery represents a novel paradigm where radiosurgery provides long-term control after tumor is surgically separated from the neural elements. PubMed, Embase, and CINAHL databases were systematically queried for literature reporting MIS techniques or separation surgery in patients with metastatic spine disease. PRISMA guidelines were followed. Of the initial 983 articles found, 29 met inclusion criteria. Twenty-five articles discussed MIS techniques and were grouped according to the primary objective: percutaneous stabilization (8), tubular retractors (4), mini-open approach (8), and thoracoscopy/endoscopy (5). The remaining 4 studies reported separation surgery. Indications were similar across all studies and included patients with instability, refractory pain, or neurologic compromise. Intraoperative variables, outcomes, and complications were similar in MIS studies compared to traditional approaches, and some MIS studies showed a statistically significant improvement in outcomes. Studies of mini-open techniques had the strongest evidence for superiority. Low-quality evidence currently exists for MIS techniques and separation surgery in the treatment of metastatic spine disease. Given the early promising results, the next iteration of research should include higher-quality studies with sufficient power, and will be able to provide higher-level evidence on the outcomes of MIS approaches and separation surgery.

Objective This study aimed to determine the feasibility and preliminary efficacy of a post-operative telephone-based cognitive behavioral therapy intervention (Tele-CBT) in improving eating pathology and psychosocial functioning. Methods Six-month post-operative bariatric surgery patients (n = 19) received six sessions of Tele-CBT. Study outcome variables included binge eating (BES), emotional eating (EES), depressive symptoms (PHQ-9), and anxiety symptoms (GAD-7). Results Retention was 73.7 % post-intervention. Tele-CBT resulted in significant reductions in mean difference scores on BES, EES-Total, EES-Anxiety, EES-Anger, PHQ9, and GAD7. Tele-CBT patients experienced a mean weight loss of 8.62 ± 15.02 kg between 6-months post-surgery (pre-Tele-CBT) and 12-months post-surgery. Conclusions These preliminary results suggest that post-surgery Tele-CBT is feasible and can improve post-surgery symptoms of psychopathology in this uncontrolled study, supporting the need for a randomized controlled trial.

Hand surgery fellowship programs in the United States are predominately sponsored by departments or divisions of orthopaedic surgery or plastic surgery. This study compares the operative experiences of hand surgery fellows graduating from orthopaedic or plastic surgery hand surgery fellowships. Operative case logs of 3 cohorts of hand surgery fellows graduating during the academic years of 2012-2013, 2013-2014, and 2014-2015 were analyzed. The median case volumes were compared by specialty via Mann-Whitney U tests. An arbitrary 1,000% change between the 90th and 10th percentiles of fellows was used as a threshold to highlight case categories with substantial variability. In this study, 413 orthopaedic hand surgery fellows (87%) and 62 plastic surgery hand surgery fellows (13%) were included. Plastic surgery fellows reported more cases in the following categories: wound closure with graft; wound reconstruction with flap; vascular repair, reconstruction, replantation, or microvascular; closed treatment of fracture or dislocation; nerve injury; and congenital (p < 0.05). Orthopaedic surgery fellows reported more cases in the following categories: wound irrigation and debridement fasciotomy or wound preparation; hand reconstruction or releases; wrist reconstruction, releases, or arthrodesis; forearm, elbow, or shoulder reconstruction or releases; hand fractures, dislocation, or ligament injury; wrist fractures or dislocations; forearm and proximal fractures or dislocations; miscellaneous insertion or removal of devices; shoulder arthroscopy, elbow arthroscopy, and wrist arthroscopy; decompression of tendon sheath, synovectomy, or ganglions; nerve decompression; Dupuytren; and tumor or osteomyelitis (p < 0.05). Plastic surgery fellows reported substantial variability for 12 case categories (range, 1,024% to 2,880%). Orthopaedic surgery fellows reported substantial variability for 9 case categories (range, 1,110% to 9,700%). Orthopaedic and plastic hand surgery fellowships afford disparate operative experiences. Understanding these differences may help to align prospective trainees with future career goals and to guide discussions to better standardize hand surgery training.

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.

Undergoing surgery with local anesthesia is stressful because patients often are aware of their surroundings. This study investigated music as a method of reducing patients' anxiety during minor surgery with local anesthesia. For this study, researchers assessed the effectiveness of music as a relaxation modality by measuring patients' vital signs and self-reported anxiety before and after surgery. Study results indicate that patients who listened to their choice of music during surgery experienced significantly lower anxiety levels, heart rates, and blood pressure than patients who did not listen to music.

Pedicle screws in spinal surgery have allowed greater biomechanical stability and higher fusion rates. However, malposition is very common and may cause neurologic, vascular, and visceral injuries and compromise mechanical stability. The purpose of this study was to compare the malposition rate between intraoperative computed tomography (CT) scan assisted-navigation and free-hand fluoroscopy-guided techniques for placement of pedicle screw instrumentation. This is a prospective, randomized, observational study. A total of 114 patients were included: 58 in the assisted surgery group and 56 in the free-hand fluoroscopy-guided surgery group. Analysis of screw position was assessed using the Heary classification. Breach severity was defined according to the Gertzbein classification. Radiation doses were evaluated using thermoluminescent dosimeters, and estimates of effective and organ doses were made based on scan technical parameters. Consecutive patients with degenerative disease, who underwent surgical procedures using the free-hand, or intraoperative navigation technique for placement of transpedicular instrumentation, were included in the study. Forty-four out of 625 implanted screws were malpositioned: 11 (3.6%) in the navigated surgery group and 33 (10.3%) in the free-hand group (p<.001). Screw position according to the Heary scale was Grade II (4 navigated surgery, 6 fluoroscopy guided), Grade III (3 navigated surgery, 11 fluoroscopy guided), Grade IV (4 navigated surgery, 16 fluoroscopy guided), and Grade V (1 fluoroscopy guided). There was only one symptomatic case in the conventional surgery group. Breach severity was seven Grade A and four Grade B in the navigated surgery group, and eight Grade A, 24 Grade B, and one Grade C in free-hand fluoroscopy-guided surgery group. Radiation received per patient was 5.8 mSv (4.8-7.3). The median dose received in the free-hand fluoroscopy group was 1 mGy (0.8-1.1). There was no detectable radiation level in the navigation-assisted surgery group, whereas the effective dose was 10 µGy in the free-hand fluoroscopy-guided surgery group. Malposition rate, both symptomatic and asymptomatic, in spinal surgery is reduced when using CT-guided placement of transpedicular instrumentation compared with placement under fluoroscopic guidance, with radiation values within the safety limits for health. Larger studies are needed to determine risk-benefit in these patients. Copyright © 2016 Elsevier Inc. All rights reserved.

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.

AIM To examine the evidence about psychiatric morbidity after inflammatory bowel disease (IBD)-related surgery. METHODS PRISMA guidelines were followed and a protocol was published at PROSPERO (CRD42016037600). Inclusion criteria were studies describing patients with inflammatory bowel disease undergoing surgery and their risk of developing psychiatric disorder. RESULTS Twelve studies (including 4340 patients) were eligible. All studies were non-randomized and most had high risk of bias. Patients operated for inflammatory bowel disease had an increased risk of developing depression, compared with surgical patients with diverticulitis or inguinal hernia, but not cancer. In addition, patients with Crohn’s disease had higher risk of depression after surgery compared with non-surgical patients. Patients with ulcerative colitis had higher risk of anxiety after surgery compared with surgical colorectal cancer patients. Charlson comorbidity score more than three and female gender were independent predictors for depression and anxiety following surgery. CONCLUSION The review cannot give any clear answer to the risks of psychiatric morbidity after surgery for IBD studies with the lowest risk of bias indicated an increased risk of depression among surgical patients with Crohn’s disease and increased risk of anxiety among patients with ulcerative colitis.

Until recently, no studies have prospectively evaluated bowel function after sphincter-preserving surgery for rectal cancer with the use of a validated bowel function scoring system. The aim of this study was to investigate possible risk factors for altered bowel function after sphincter-preserving surgery. This was a prospective study. The study was conducted between January 2006 and May 2012 at the authors' institution. Patients who underwent sphincter-preserving rectal cancer surgery were recruited. Bowel function was assessed 1 day before (baseline) and at 1 year after sphincter-preserving surgery or temporary ileostomy takedown with the use of the Memorial Sloan Kettering Cancer Center questionnaire. Multivariable analysis was performed to identify the factors associated with altered bowel function after surgery. Overall, 266 patients were eligible for the analysis. The tumor was located in the upper, middle, and lower rectum in 68 (25.5%), 113 (42.5%), and 85 (32.0%) patients. Intersphincteric resection and temporary ileostomy were performed in 18 (6.8%) and 129 (48.5%) patients. The mean Memorial Sloan Kettering Cancer Center score was 64.5 ± 7.6 at 1 year after sphincter-preserving surgery or temporary ileostomy takedown. The Memorial Sloan Kettering Cancer Center score decreased in 163/266 patients (61.3%) between baseline and 1 year after surgery. Tumor location (p = 0.01), operative method (p = 0.03), anastomotic type (p = 0.01), and temporary ileostomy (p = 0.01) were associated with altered bowel function after sphincter-preserving surgery in univariate analyses. In multivariable analysis, only tumor location was independently associated with impaired bowel function after sphincter-preserving rectal cancer surgery. This study was limited by its nonrandomized design and the lack of measurement before preoperative chemoradiotherapy. We suggest that preoperative counseling should be implemented to inform patients of the risk of bowel dysfunction, especially in patients with lower rectal cancer, although this study cannot exclude the effect of chemoradiotherapy owing to the limitation of study.

To understand the functional and psychosocial aspects of strabismus surgery, an evaluation based on the patient's perspective is essential. In this study, we assessed quality of life and utility in adult patients who had undergone strabismus surgery, and we modeled the cost of providing this intervention in order to calculate the cost-utility of strabismus surgery in adults. The study population comprised 226 patients with strabismus aged 18 years or older who were scheduled for ocular alignment surgery at 12 facilities of the Strabismus Surgery Study Group in Japan. Survey questionnaires consisting of the Japanese versions of the Visual Function Questionnaire-25 (VFQ-25) and 8-Item Short-Form Health Survey (SF-8) and utility assessment by a time trade-off method were administrated preoperatively and 3 months postoperatively. On the basis of the cost model and measured utility data, the gains in quality-adjusted life years (QALYs) and $/QALY were estimated. Postoperatively, the subscale scores of the VFQ-25 and the physical and mental component summary scores of the SF-8 showed a statistically significant improvement. A significant improvement of utility was also noted: 0.82 ± 0.28 postoperatively versus 0.76 ± 0.31 preoperatively. On the basis of the life expectancy of these patients and the cost model, the surgery resulted in a mean value gain of 0.99 QALYs and a cost-utility for strabismus surgery of 1,303 $/QALY. By using standard tools to assess vision-associated and general health status, we confirmed the psychosocial benefits of corrective surgery for adults with strabismus. Our study concurrently demonstrated that strabismus surgery in adults is very cost-effective.

Objective After radiation failure for early T-stage larynx cancer, national guidelines recommend salvage surgery. Total laryngectomy and conservation laryngeal surgery with an open or endoscopic approach are both used. Beyond single-institution studies, there is a lack of evidence concerning the outcomes of these procedures. We aim to study whether treatment with conservation laryngeal surgery is associated with poorer outcomes than treatment with total laryngectomy as salvage surgery after radiation failure for T1/T2 larynx cancers. Study Design A retrospective study was conducted of adult squamous cell larynx cancer cases in the National Cancer Database diagnosed from 2004 to 2012. Setting Commission on Cancer cancer programs in the United States. Methods Demographic, facility, tumor, and survival variables were included in the analyses. Multivariate survival regressions as well as univariate Kaplan-Meier analyses were conducted. Results Slightly more than 7% of patients receiving radiotherapy for T1/T2 larynx cancers later received salvage surgery. Salvage with partial laryngectomy was not associated with diminished survival as compared with total laryngectomy. However, positive surgical margins were associated with worse outcomes (hazard ratio, 1.782; P = .001), and a larger percentage of patients receiving partial laryngectomy had positive margins than those receiving total laryngectomy. Facility characteristics were not associated with differences in salvage surgery type or outcomes. Conclusion In recognition of the inherent selection bias, patients who experienced recurrences after radiation for T1/T2 larynx cancer and underwent conservation salvage laryngeal surgery demonstrated clinical outcomes similar to those of patients undergoing salvage total laryngectomy. Increased rates of positive surgical margins were observed among patients undergoing salvage conservation surgery.

A systematic review and meta-analysis was conducted to answer the clinical question "Does the piezoelectric surgical technique produce fewer postoperative sequelae after lower third molar surgery than conventional rotary instruments?" A systematic and electronic search of several databases with specific key words, a reference search, and a manual search were performed from respective dates of inception through November 2014. The inclusion criteria were clinical human studies, including randomized controlled trials (RCTs), controlled clinical trials (CCTs), and retrospective studies, with the aim of comparing the piezoelectric surgical osteotomy technique to the standard rotary instrument technique in lower third molar surgery. Postoperative sequelae (oedema, trismus, and pain), the total number of analgesics taken, and the duration of surgery were analyzed. A total of nine articles were included, six RCTs, two CCTs, and one retrospective study. Six studies had a low risk of bias and three had a moderate risk of bias. A statistically significant difference was found between piezoelectric surgery and conventional rotary instrument surgery for lower third molar extraction with regard to postoperative sequelae (oedema, trismus, and pain) and the total number of analgesics taken (P=0.0001, P=0.0001, P<0.00001, and P<0.0001, respectively). However, a statistically significant increased surgery time was required in the piezoelectric osteotomy group (P<0.00001). The results of the meta-analysis showed that piezoelectric surgery significantly reduced the occurrence of postoperative sequelae (oedema, trismus, and pain) and the total number of analgesics taken compared to the conventional rotary instrument technique in lower third molar surgery, but required a longer surgery time.

Systemic inflammatory response syndrome (SIRS) is a common complication after cardiovascular surgery that in severe cases can lead to multiple organ dysfunction syndrome and even death. We therefore set out to identify reliable early biomarkers for SIRS in a prospective small patient study for timely intervention. 21 Patients scheduled for planned cardiovascular surgery were recruited in the study, monitored for signs of SIRS and blood samples were taken to investigate biomarkers at pre-assigned time points: day of admission, start of surgery, end of surgery, days 1, 2, 3, 5 and 8 post surgery. Stored plasma and cryopreserved blood samples were analyzed for cytokine expression (IL1β, IL2, IL6, IL8, IL10, TNFα, IFNγ), other pro-inflammatory markers (sCD163, sTREM-1, ESM-1) and response to endotoxin. Acute phase proteins CRP, PCT and pro-inflammatory cytokines IL6 and IL8 were significantly increased (p<0.001) at the end of surgery in all patients but could not distinguish between groups. Normalization of samples revealed significant increases in IL1β changes (p<0.05) and decreased responses to endotoxin (p<0.01) in the SIRS group at the end of surgery. Soluble TREM-1 plasma concentrations were significantly increased in patients with SIRS (p<0.01). This small scale patient study could show that common sepsis markers PCT, CRP, IL6 and TNFα had low predictive value for early diagnosis of SIRS after cardiovascular surgery. A combination of normalized IL1β plasma levels, responses to endotoxin and soluble TREM-1 plasma concentrations at the end of surgery are predictive markers of SIRS development in this small scale study and could act as an indicator for starting early therapeutic interventions.

The aim of this study was to describe changes over time in the indications and outcomes of cataract surgery and to discuss optimal timing for the surgery. Database study. Patients who had undergone cataract extraction in the Netherlands, Sweden, or Malaysia from 2008 through 2012. We analyzed preoperative, surgical, and postoperative data from 2 databases: the European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO) and the Malaysian National Cataract Registry. The EUREQUO contains complete data from the national cataract registries in the Netherlands and Sweden. Preoperative and postoperative corrected distance visual acuity, preoperative ocular comorbidity in the surgery eye, and capsule complications during surgery. There were substantial differences in indication for surgery between the 3 national data sets. The percentage of eyes with a preoperative best-corrected visual acuity of 20/200 or worse varied from 7.1% to 72%. In all 3 data sets, the visual thresholds for cataract surgery decreased over time by 6% to 28% of the baseline values. The frequency of capsule complications varied between the 3 data sets, from 1.1% to 3.7% in 2008 and from 0.6% to 2.7% in 2012. An increasing postoperative visual acuity was also seen for all 3 data sets. A high frequency of capsule complication was related significantly to poor preoperative visual acuity, and a high frequency of decreased visual acuity after surgery was related significantly to excellent preoperative visual acuity. The 5-year trend in all 3 national data sets showed decreasing visual thresholds for surgery, decreasing surgical complication rates, and increasing visual outcomes regardless of the initial preoperative visual level. Cataract surgery on eyes with poor preoperative visual acuity was related to surgical complications, and cataract surgery on eyes with excellent preoperative visual acuity was related to adverse visual results.

This study aimed to review the evidence of the effectiveness of pitch-raising surgery performed in male-to-female transsexuals. A search for studies was performed in PubMed, Web of Science, Science Direct, EBSCOhost, Google Scholar, and the references in retrieved manuscripts, using as keywords "transsexual" or "transgender" combined with terms related to voice surgery. We included eight studies using cricothyroid approximation, six studies using anterior glottal web formation, and six studies using other surgery types or a combination of surgical techniques, leading to 20 studies in total. Objectively, a substantial rise in postoperative fundamental frequency was identified. Perceptually, mainly laryngeal web formation seems risky for decreasing voice quality. The majority of patients seemed satisfied with the outcome. However, none of the studies used a control group and randomization process. Further investigation regarding long-term results is necessary. Future research needs to investigate long-term effects of pitch-raising surgery using a stronger study design.

Impact of Ischemic Preconditioning on Outcome in Clinical Liver Surgery: A Systematic Review

PubMed Central

Chu, Michael J. J.; Vather, Ryash; Hickey, Anthony J. R.; Phillips, Anthony R. J.; Bartlett, Adam S. J. R.

2015-01-01

Background. Ischemia-reperfusion injury is a major cause of post-liver-surgery complications. Ischemic preconditioning (IPC) has been demonstrated to protect against ischemia-reperfusion injury. Clinical studies have examined IPC in liver surgery but with conflicting results. This systematic review aimed to evaluate the effects of IPC on outcome in clinical liver surgery. Methods. An electronic search of OVID Medline and Embase databases was performed to identify studies that reported outcomes in patients undergoing liver surgery subjected to IPC. Basic descriptive statistics were used to summarise data from individual clinical studies. Results. 1093 articles were identified, of which 24 met the inclusion criteria. Seven topics were selected and analysed by subgroup. There were 10 studies in cadaveric liver transplantation, 2 in living-related liver transplantation, and 12 in liver resection. IPC decreases hepatocellular damage in liver surgery as determined by transaminases but does not translate to any significant clinical benefit in orthotopic liver transplant or liver resection. Conclusions. Available clinical evidence does not support routine use of IPC in liver surgery as it does not offer any apparent benefit in perioperative outcome. Further clinical studies will need to be carried out to determine the subset of patients that will benefit from IPC. PMID:25756045

Analysis of a private insurer's administrative data set revealed significant variation in the length of hospital stay following hernia surgery. This review examined factors influencing the performance of day surgery for inguinal, femoral and umbilical hernia repair in adults. A systematic literature search was conducted in the PubMed, Embase and Cochrane Library databases to identify studies and clinical practice guidelines (CPGs) comparing same day hernia surgery to surgery followed by an overnight stay. Screening of studies by abstract and full text was completed by a single researcher and checked by a second. Studies were selected for inclusion based on a step-wise approach across three phases. Limited evidence from one systematic review, and three case series studies including 3213 patients found that same day hernia surgery was as safe and effective as an overnight stay. All identified CPGs recommended a same day procedure for most patients. Two case series studies reported that 3-8% of patients were ineligible for day procedures due to medical reasons; however, the characteristics of patients, in general, which are not suitable, have not been adequately investigated. Day surgery for groin hernia repair is safe and effective for most patients. However, evidence-based support is only one of many factors that may contribute to the uptake of day surgery in Australia. There is an opportunity for key stakeholders across the private healthcare system to deliver an equally effective but more sustainable and affordable hernia care by increasing the day surgery rates. © 2018 Royal Australasian College of Surgeons.

Evaluation of surgery outcome measured by patient satisfaction or quality of life is very important, especially in plastic surgery. There is increasing interest in self-reporting outcomes evaluation in plastic surgery. The aim of our study was to determine patient satisfaction in regard to nose appearance and function with the use of a validated questionnaire, before and after rhinoplasty surgery. A prospective study was realized at a tertiary centre. All rhinoplasty surgeries performed in adults between February 2013 and August 2014 were included. Many patients underwent additional nasal surgery such as septoplasty or turbinoplasty. The surgical procedures and patients' characteristics were also recorded. Among 113 patients, 107 completed the questionnaires and the follow-up period. Analysis of pre-operative and post-operative Rhinoplasty Evaluation Outcome showed a significant improvement after 3 and 6 months in functional and aesthetic questions (p<0.01). In the pre-operative, patients anxious and insecure had a worse score (p<0.05). Difference in improvement of scores was not significant when groups were divided on basis of other nasal procedures, primary or revision surgery and open versus closed approach. We found that patients with lower literacy degree were more satisfied with the procedure. Rhinoplasty surgery significantly improved patient quality of life regarding nose function and appearance.

Access to affordable and timely surgery is not equitable around the world. Five billion people lack access, and while non-governmental organizations (NGOs) help to meet this need, long-term surgical outcomes, social impact or patient experience is rarely reported. In 2016, Mercy Ships, a surgical NGO, undertook an evaluation of patients who had received surgery seven years earlier with Mercy Ships in 2009 in Benin. Using purposive sampling, patients who had received maxillofacial, plastics or orthopedic surgery were invited to attend a surgical evaluation day. In this pilot study, we used semi-structured interviews and questionnaire responses to assess patient expectation, surgical and social outcome. Our results show that seven years after surgery 35% of patients report surgery-related pain and 18% had sought further care for a clinical complication of their condition. However, 73% of patients report gaining social benefit from surgery, and overall patient satisfaction was 89%, despite 35% of patients saying that they were unclear what to expect after surgery indicating a mismatch of doctor/patient expectations and failure of the consent process. In conclusion, our pilot study shows that NGO surgery in Benin provided positive social impact associated with complication rates comparable to high-income countries when assessed seven years later. Key areas for further study in LMICs are: evaluation and treatment of chronic pain, consent and access to further care.

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.

Obesity surgery involves mechanical and physiological changes of the gastrointestinal tract that might promote colorectal cancer progression. Thus, we hypothesised that obesity surgery is associated with poorer prognosis in patients with colorectal cancer. This nationwide population-based cohort study included all patients with an obesity diagnosis who subsequently developed colorectal cancer in Sweden from 1980 to 2012. The exposure was obesity surgery, and the main and secondary outcomes were disease-specific mortality and all-cause mortality, respectively. Cox proportional hazard survival models were used to calculate hazard ratios (HRs) with 95% confidence intervals (CIs), adjusted for sex, age, calendar year and education level. The exposed and unexposed cohort included 131 obesity surgery and 1332 non-obesity surgery patients with colorectal cancer. There was a statistically significant increased rate of colorectal cancer deaths following obesity surgery (disease-specific HR 1.50, 95% CI 1.00-2.19). When analysed separately, the mortality rate was more than threefold increased in rectal cancer patients with prior obesity surgery (disease-specific HR 3.70, 95% CI 2.00-6.90), while no increased mortality rate was found in colon cancer patients (disease-specific HR 1.10, 85% CI 0.67-1.70). This population-based study among obese individuals found a poorer prognosis in colorectal cancer following obesity surgery, which was primarily driven by the higher mortality rate in rectal cancer.

The aim of the present study was to evaluate the clinical results of pars plana vitrectomy (PPV) combined with the surgical enlargement of internal limiting membrane (ILM) peeling in patients who had previously undergone failed idiopathic macular hole (IMH) surgery. In the study, 134 eyes from 130 IMH patients who had received PPV combined with ILM peeling surgery (2 disk diameters) were analyzed. Within this cohort, 14 eyes had IMHs that were not closed, of which 13 eyes underwent a second surgery involving enlargement of the ILM peeling. The extent of the ILM peeling was increased to the vascular arcades of the posterior fundus in the secondary surgery. Of the 13 eyes that underwent secondary surgery, five were in stage III and nine were in stage IV. The second surgery successfully achieved IMH closure in 61.5% (8/13) of the eyes. The IMH was completely closed following surgery and the logMAR vision increased from 0.98 to 0.84 (P=0.013) in the 8 successfully treated cases. The surgical enlargement of ILM peeling closed the IMHs and improved vision in the majority of patients. In addition, the procedures were safe. Therefore, the results of the present study indicate that enlargement of ILM peeling may be an effective therapy for patients who have previously undergone the failed surgical correction of an IMH.

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.

Telepresence surgery is a novel technology that will allow procedures to be performed on a patient at locations that are physically remote from the operating surgeon. This new method provides the sensory illusion that the surgeon's hands are in direct contact with the patient. We studied the feasibility of the use of telepresence surgery to perform basic operations in vascular surgery, including tissue dissection, vessel manipulation, and suturing. A prototype telepresence surgery system with bimanual force-reflective manipulators, interchangeable surgical instruments, and stereoscopic video input was used. Arteriotomies created ex vivo in segments of bovine aortae or in vivo in femoral arteries of anesthetized swine were closed with telepresence surgery or by conventional techniques. Time required, technical quality (patency, integrity of suture line), and subjective difficulty were compared for the two methods. All attempted procedures were successfully completed with telepresence surgery. Arteriotomy closures were completed in 192+/-24 sec with conventional techniques and 483+/-118 sec with telepresence surgery, but the precision attained with telepresence surgery was equal to that of conventional techniques. Telepresence surgery was described as intuitive and natural by the surgeons who used the system. Blood-vessel manipulation and suturing with telepresence surgery are feasible. Further instrument development (to increase degrees of freedom) is required to achieve operating times comparable to conventional open surgery, but the system has great potential to extend the expertise of vascular surgeons to locations where specialty care is currently unavailable.

Several outcomes of pregnancy after bariatric surgery are currently being studied. This cross-sectional, retrospective study evaluated the obstetric and perinatal outcomes of pregnancies in 19 women who underwent bariatric surgery, as well as the growth and development of their children, in the Southern Brazil. Among these women, 11 children were born prior to surgery and 32 were born post-surgery. The mean time between the surgery and the first pregnancy was 42.96 months. Preterm newborns were more common among the pre-surgery childbirths. Regarding growth, normal weights were observed in 27.3 % of the children in the pre-surgery births and obesity was observed in 54.5 %. In contrast, normal weights were observed in 59.4 % of the children born during the postoperative period and obesity was observed in 31.2 %. The average excess weight that the women lost prior to pregnancy was 64.88. Speech delays were found in three male children evaluated using the Denver Developmental Screening Test II. A statistical association was found between the interval from the surgery to the pregnancy and the outcome of the questionable Denver II test results (p = 0.011). Except for the large index of low birth weight, it can be concluded that pregnancy after bariatric surgery is safe. The growth rate was found to be adequate in the children born after the surgery, with reduced obesity. Although changes in speech development were detected, no factors were supported an association with pregnancy after bariatric surgery.

This study summarises the results of a National Audit of sino-nasal surgery carried out in England and Wales. It describes patient and operative characteristics as well as patient outcomes up to 36 months after surgery. Prospective cohort study. NHS hospitals in England and Wales. Consecutive patients undergoing surgery for nasal polyposis and/or chronic rhinosinusitis. The total score derived from a 22-item version of the Sino-Nasal Outcome Test (SNOT-22). Lower scores represent better health-related quality of life. A total of 3128 consecutive patients at 87 NHS hospitals were enrolled. There is a large improvement in SNOT-22 scores from the pre-operative period (mean = 42.0) to 3 months after surgery (mean = 25.5). The scores for patients undergoing nasal polypectomy improved from 41.0 before surgery to 23.1 at 3 months after surgery, while the scores for patients undergoing surgery for chronic rhinosinusitis alone improved from 44.2 to 31.2. The SNOT-22 scores reported at 12 and 36 months after surgery were similar to those reported at 3 months. Excessive bleeding occurred in 5% of patients during the operation and in 1% of patients after the operation. Intra-orbital complications were reported in 0.2%. Of those patients undergoing primary surgery for bilateral grade I or II polyposis, 18% had not received a pre-operative course of steroid treatment. At the 36-month follow-up, 11.4% of patients had undergone revision surgery. The audit confirms that sino-nasal surgery is generally safe and effective. There is some evidence that patient selection for surgery could be improved.

Background Risk factors associated with postoperative pain intensity and duration, as well as consumption of analgesics after ophthalmic surgery are poorly understood. Methods A prospective study was conducted among adults (N=226) who underwent eye surgery at the University Hospital Split, Croatia. A day before the surgery, the patients filled out questionnaires assessing personality, anxiety, pain catastrophizing, sociodemographics and were given details about the procedure, anesthesia, and analgesia for each postoperative day. All scales were previously used for the Croatian population. The intensity of pain was measured using a numerical rating scale from 0 to 10, where 0 was no pain and 10 was the worst imaginable pain. The intensity of pain was measured before the surgery and then 1 hour, 3 hours, 6 hours, and 24 hours after surgery, and then once a day until discharge from the hospital. Univariate and multivariate analyses were performed. Results A multivariate analysis indicated that independent predictors of average pain intensity after the surgery were: absence of premedication before surgery, surgery in general anesthesia, higher pain intensity before surgery and pain catastrophizing level. Independent predictors of postoperative pain duration were intensity of pain before surgery, type of anesthesia, and self-assessment of health. Independent predictors of pain intensity ≥5 during the first 6 hours after the procedure were the type of procedure, self-assessment of health, premedication, and the level of pain catastrophizing. Conclusion Awareness about independent predictors associated with average postoperative pain intensity, postoperative pain duration, and occurrence of intensive pain after surgery may help health workers to improve postoperative pain management in ophthalmic surgery.

Untreated trichiasis can lead to corneal opacity. Surgery to prevent the eyelashes from rubbing against the cornea is available, but many individuals with trichiasis never undergo the operation. This study estimates the cost of illness of untreated trichiasis and the willingness to pay for surgery and compares them with the actual cost of providing surgery. The cost of illness estimate is based on trichiasis patient demographics. Data on the implicit price of obtaining surgery and surgical utilization in a matched pair randomized trial are used to infer individual willingness to pay for trichiasis surgery. Patients in the study paid nothing out-of-pocket for surgery; the price of obtaining surgery is the value of the individual's time needed for travel and surgery plus the price of public transportation. The cost of producing surgery was calculated from project records. All monetary figures are reported in 1998 US dollars. The average cost of untreated trichiasis, or the net present value of life-time lost economic productivity, was $89. Individuals facing a lower cost were more likely to undergo an operation; the inferred average willingness to pay was $1.43 (SD 0.244). Surgery cost $6.13 to provide, including $0.86 for transportation to the village. Whether the value of trichiasis surgery exceeds the cost in The Gambia depends on how the value is measured. Individuals are willing to use only limited resources to obtain surgery even though lifetime economic productivity may increase substantially. All three economic measures can be used to inform policy.

The Association of Surgeons of South Africa (ASSA), because of a concern about the decline in the number of applicants for registrar posts, undertook this study into the various factors that may influence the choice of surgery as career option. The study involved a combination of desk research and structured interviews with heads of departments, specialists, and registrars in general surgery. The reasons for choosing general surgery as a career included the immediately visible results of a surgeon's efforts and the practical and intellectual challenge of the specialty. General surgery continued to enjoy a high status in society. The greater focus on primary health care has affected facilities at tertiary and secondary institutions. General surgeons worked excessively long hours, which was associated with increased levels of stress and placed severe strains on family life. All respondents felt that their levels of remuneration were 'poor' in relation to other disciplines and professions. In this study we identified various factors that impacted either positively or negatively on the choice of general surgery as a career option.

Sentinel lymph node navigation surgery for gastric cancer: Does it really benefit the patient?

Sentinel lymph node (SLN) navigation surgery is accepted as a standard treatment procedure for malignant melanoma and breast cancer. However, the benefit of reduced lymphadenectomy based on SLN examination remains unclear in cases of gastric cancer. Here, we review previous studies to determine whether SLN navigation surgery is beneficial for gastric cancer patients. Recently, a large-scale prospective study from the Japanese Society of Sentinel Node Navigation Surgery reported that the endoscopic dual tracer method, using a dye and radioisotope for SLN biopsy, was safe and effective when applied to cases of superficial and relatively small gastric cancers. SLN mapping with SLN basin dissection was preferred for early gastric cancer since it is minimally invasive. However, previous studies reported that limited gastrectomy and lymphadenectomy may not improve the patient's postoperative quality of life (QOL). As a result, the benefit of SLN navigation surgery for gastric cancer patients, in terms of their QOL, is limited. Thus, endoscopic and laparoscopic limited gastrectomy combined with SLN navigation surgery has the potential to become the standard minimally invasive surgery in early gastric cancer.

Aim: While the incidence of rheumatic heart disease has declined dramatically over the last half-century, the number of valve surgeries has not changed. This study was undertaken to define the most common type of valvular heart disease requiring surgery today, and determine in-hospital surgical mortality and length-of-stay (LOS) for isolated aortic or mitral valve surgery in a United States tertiary-care hospital. Methods: Patients with valve surgery between January 2002 to June 2008 at The Ohio State University Medical Center were studied. Patients only with isolated aortic or mitral valve surgery were analyzed. Results: From 915 patients undergoing at least aortic or mitral valve surgery, the majority had concomitant cardiac proce-dures mostly coronary artery bypass grafting (CABG); only 340 patients had isolated aortic (n=204) or mitral (n=136) valve surgery. In-hospital surgical mortality for mitral regurgitation (n=119), aortic stenosis (n=151), aortic insufficiency (n=53) and mitral stenosis (n=17) was 2.5% (replacement 3.4%; repair 1.6%), 3.9%, 5.6% and 5.8%, respectively (p=NS). Median LOS for aortic insufficiency, aortic stenosis, mitral regurgitation, and mitral stenosis was 7, 8, 9 (replacement 11.5; repair 7) and 11 days, respectively (p<0.05 for group). In-hospital surgical mortality for single valve surgery plus CABG was 10.2% (p<0.005 compared to single valve surgery). Conclusions: Aortic stenosis and mitral regurgitation are the most common valvular lesions requiring surgery today. Surgery for isolated aortic or mitral valve disease has low in-hospital mortality with modest LOS. Concomitant CABG with valve surgery increases mortality substantially. Hospital analysis is needed to monitor quality and stimulate improvement among Institutions. PMID:24339838

The low-grade inflammatory condition present in morbid obesity is thought to play a causative role in the pathophysiology of insulin resistance (IR). Bariatric surgery fails to improve this inflammatory condition during the first months after surgery. Considering the close relation between inflammation and IR, we conducted a study in which insulin sensitivity was measured during the first months after bariatric surgery. Different methods to measure IR shortly after bariatric surgery have given inconsistent data. For example, the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) levels have been reported to decrease rapidly after bariatric surgery, although clamp techniques have shown sustained insulin resistance. In the present study, we evaluated the use of steady-state plasma glucose (SSPG) levels to assess insulin sensitivity 2 months after bariatric surgery. Insulin sensitivity was measured using HOMA-IR and SSPG levels in 11 subjects before surgery and at 26% excess weight loss (approximately 2 months after restrictive bariatric surgery). The SSPG levels after 26% excess weight loss did not differ from the SSPG levels before surgery (14.3 +/- 5.4 versus 14.4 +/- 2.7 mmol/L). In contrast, the HOMA-IR values had decreased significantly (3.59 +/- 1.99 versus 2.09 +/- 1.02). During the first months after restrictive bariatric surgery, we observed a discrepancy between the HOMA-IR and SSPG levels. In contrast to the HOMA-IR values, the SSPG levels had not improved, which could be explained by the ongoing inflammatory state after bariatric surgery. These results suggest that during the first months after restrictive bariatric surgery, HOMA-IR might not be an adequate marker of insulin sensitivity.

Surgery offers the potential to relieve symptoms for patients with cancer at the end of life (EOL) but at significant physiological and economic costs. However, the characteristics and correlates of surgery in last month of life (EOL surgery) of patients with cancer have not been comprehensively explored. This population-based study characterized EOL surgery use and identified its correlates. This retrospective cohort study examined administrative data among 339,546 Taiwanese cancer decedents, 2001 to 2010. We classified procedures according to their likely intent. Approximately 1 in 10 (11.44%, range: 11.08%-11.86%) patients underwent EOL surgery with an increasing utilization over time. The intention for EOL surgery was primarily palliative, followed by cancer-directed, nonmalignancy-directed, and diagnostic. EOL surgery for palliative intent increased whereas other intents decreased significantly over time. EOL surgery was more likely among those who were male, younger, and married; not diagnosed with hepatic-pancreatic or lung cancers; had no comorbidity or documented metastatic codes; and survived less than 1 year from diagnosis. The likelihood of EOL surgery use was higher for patients who received care in a teaching hospital with more acute care hospital beds and higher EOL care intensity. Rates of EOL surgery are lower in Taiwan than those reported in the United States. The increasing use of EOL surgery in Taiwan is primarily for palliative intent. Appropriateness of EOL surgery should be carefully evaluated to avoid underutilizing potentially beneficial, palliative-intent surgery and overutilizing cancer-directed and other surgical procedures, especially for physicians working in hospitals with abundant health care resources and a tendency to treat at-risk patients with cancer aggressively.

The Society of Thoracic Surgeons 2008 cardiac surgery risk models have been developed for heart valve surgery with and without coronary artery bypass grafting. The aim of our study was to evaluate the performance of Society of Thoracic Surgeons 2008 cardiac risk models in Chinese patients undergoing single valve surgery and the predicted mortality rates of those undergoing multiple valve surgery derived from the Society of Thoracic Surgeons 2008 risk models. A total of 12,170 patients underwent heart valve surgery from January 2008 to December 2011. Combined congenital heart surgery and aortal surgery cases were excluded. A relatively small number of valve surgery combinations were excluded. The final research population included the following isolated heart valve surgery types: aortic valve replacement, mitral valve replacement, and mitral valve repair. The following combined valve surgery types were included: mitral valve replacement plus tricuspid valve repair, mitral valve replacement plus aortic valve replacement, and mitral valve replacement plus aortic valve replacement and tricuspid valve repair. Evaluation was performed by using the Hosmer-Lemeshow test and C-statistics. Data from 9846 patients were analyzed. The Society of Thoracic Surgeons 2008 cardiac risk models showed reasonable discrimination and poor calibration (C-statistic, 0.712; P = .00006 in Hosmer-Lemeshow test). Society of Thoracic Surgeons 2008 models had better discrimination (C-statistic, 0.734) and calibration (P = .5805) in patients undergoing isolated valve surgery than in patients undergoing multiple valve surgery (C-statistic, 0.694; P = .00002 in Hosmer-Lemeshow test). Estimates derived from the Society of Thoracic Surgeons 2008 models exceeded the mortality rates of multiple valve surgery (observed/expected ratios of 1.44 for multiple valve surgery and 1.17 for single valve surgery). The Society of Thoracic Surgeons 2008 cardiac surgery risk models performed well when predicting the mortality for Chinese patients undergoing valve surgery. The Society of Thoracic Surgeons 2008 models were suitable for single valve surgery in a Chinese population; estimates of mortality for multiple valve surgery derived from the Society of Thoracic Surgeons 2008 models were less accurate.

Bromelain is the name given to a family of proteolytic enzymes obtained from Ananas comosus, the pineapple plant. It is considered a potent anti-inflammatory and antiedematous substance. Surgery of impacted third molars in the outpatient setting is one of the procedures most often associated with postoperative pain and swelling. The aim of this study was to evaluate the efficacy of bromelain in reducing postoperative pain and swelling. 80 patients were recruited to the study from patients attending the Maxillofacial Surgery Unit of the Istituto Stomatologico Italiano, Milan, Italy, for impacted third molar surgery. At time 0 when surgery was performed, patients started simultaneous antibiotic and analgesic therapy. On the following day, patients were divided into two groups. Patients in group 1 were prescribed bromelain. Patients in group 2 were prescribed only the analgesic if required. Three parameters were evaluated: pain, edema, and erythema. The first evaluation visit was performed 3 hours after surgery, the second 48 hours after surgery, and the final evaluation 7 days after surgery. Postoperative pain, edema, and erythema were significantly lower in the study group than in the control group. Analgesic consumption, both in terms of days of treatment and number of tablets taken, was slightly lower in the study group. Only one adverse event was recorded, which occurred in a patient in the control group. The present study demonstrates an important anti-inflammatory and anti-edematous effect of bromelain. Statistical analysis shows that in the group treated with bromelain the inflammatory response was significantly less than in the control group.

The aims of our study were to identify studies that evaluated patient satisfaction following post-bariatric surgery, analyse existing questionnaires, and summarise their development, psychometric properties, and content. A multistep search was undertaken on the web-based PubMed database from the National Library of Medicine to identify studies on patient satisfaction and quality of life following post-bariatric surgery. The authors summarised all the questionnaires used in every study and categorised them as generic, surgery specific, or ad hoc, and whether they contained either validated or unvalidated measures. Our search generated a total of 1754 articles. We performed a systematic review of the 12 remaining studies, because these had sufficient data and met the inclusion criteria. All the studies identified from the literature review were assessed to determine the type of surgery used, and whether or not the questionnaire used to analyse patient satisfaction had been validated. The questionnaires were analysed by reviewers to assess adherence to the rules of the US Food and Drug Administration and the Scientific Advisory Committee of the Medical Outcomes Trust. We identified 20 individual questionnaires that included 10 generic instruments that assessed quality of life, six instruments specific for post-bariatric surgery, three instruments specific for breast surgery. In post-bariatric patients, the BODY-Q was shown to be a more objective and confident measure for evaluating the quality of life of patients following post-bariatric surgery.

Actigraphy for Measurement of Sleep and Sleep-Wake Rhythms in Relation to Surgery

PubMed Central

Madsen, Michael T.; Rosenberg, Jacob; Gögenur, Ismail

2013-01-01

Study Objectives: Patients undergoing surgery have severe sleep and sleep-wake rhythm disturbances resulting in increased morbidity. Actigraphy is a tool that can be used to quantify these disturbances. The aim of this manuscript was to present the literature where actigraphy has been used to measure sleep and sleep-wake rhythms in relation to surgery. Methods: A systematic review was performed in 3 databases (Medline, Embase, and Psycinfo), including all literature until July 2012. Results: Thirty-two studies were included in the review. Actigraphy could demonstrate that total sleep time and sleep efficiency was reduced after surgery and number of awakenings was increased in patients undergoing major surgery. Disturbances were less severe in patients undergoing minor surgery. Actigraphy could be used to differentiate between delirious and non-delirious patients after major surgery. Actigraphy measurements could determine a differential effect of surgery based on the patient's age. The effect of pharmacological interventions (chronobiotics and hypnotics) in surgical patients could also be demonstrated by actigraphy. Conclusion: Actigraphy can be used to measure sleep and sleep-wake rhythms in patients undergoing surgery. Citation: Madsen MT; Rosenberg J; Gögenur I.

In general, the treatment methods for esophageal achalasia are largely classified into four groups, including drug therapy using nitrite or a calcium channel blocker, botulinum toxin injection, endoscopic therapy such as endoscopic balloon dilation, and surgery. Various studies have suggested that the most effective treatment of esophageal achalasia is surgical therapy. The basic concept of this surgical therapy has not changed since Heller proposed esophageal myotomy for the purpose of resolution of lower esophageal obstruction for the first time in 1913, but the most common approach has changed from open-chest surgery to laparoscopic surgery. Currently, the laparoscopic surgery has been the procedure of choice for the treatment of esophageal achalasia. During the process of the transition from open-chest surgery to laparotomy, to thoracoscopic surgery, and to laparoscopic surgery, the necessity of combining antireflux surgery has been recognized. There is some debate as to which type of antireflux surgery should be selected. The Toupet fundoplication may be the most effective in prevention of postoperative antireflux, but many medical institutions have selected the Dor fundoplication which covers the mucosal surface exposed by myotomy. Recently, a new endoscopic approach, peroral endoscopic myotomy (POEM), has received attention. Future studies should examine the long-term outcomes and whether POEM becomes the gold standard for the treatment of esophageal achalasia.

Comprehensive information regarding causes of late post-operative death following pediatric congenital cardiac surgery is lacking. The study sought to analyze late causes of death after congenital cardiac surgery by era and defect severity. We obtained data from a nationwide pediatric cardiac surgery database and Finnish population registry regarding patients who underwent cardiac surgery at <15 years of age at 1 of 5 universities or 1 district hospital in Finland from 1953 to 2009. Noncyanotic and cyanotic defects were classified as simple and severe, respectively. Causes of death were determined using International Classification of Diseases diagnostic codes. Deaths among the study population were compared to a matched control population. Overall, 10,964 patients underwent 14,079 operations, with 98% follow-up. Early mortality (<30 days) was 5.6% (n = 613). Late mortality was 10.4% (n = 1,129). Congenital heart defect (CHD)-related death rates correlated with defect severity. Heart failure was the most common mode of CHD-related death, but decreased after surgeries performed between 1990 and 2009. Sudden death after surgery for atrial septal defect, ventricular septal defect, tetralogy of Fallot, and transposition of the great arteries decreased to zero following operations from 1990 to 2009. Deaths from neoplasms, respiratory, neurological, and infectious disease were significantly more common among study patients than controls. Pneumonia caused the majority of non-CHD-related deaths among the study population. CHD-related deaths have decreased markedly but remain a challenge after surgery for severe cardiac defects. Premature deaths are generally more common among patients than the control population, warranting long-term follow-up after congenital cardiac surgery.

Fourman, Matthew M; Saber, Alan A

2012-01-01

Obesity is a nationwide epidemic, and the only evidence-based, durable treatment of this disease is bariatric surgery. This field has evolved drastically during the past decade. One of the latest advances has been the increased use of robotics within this field. The goal of our study was to perform a systematic review of the recent data to determine the safety and efficacy of robotic bariatric surgery. The setting was the University Hospitals Case Medical Center (Cleveland, OH). A PubMed search was performed for robotic bariatric surgery from 2005 to 2011. The inclusion criteria were English language, original research, human, and bariatric surgical procedures. Perioperative data were then collected from each study and recorded. A total of 18 studies were included in our review. The results of our systematic review showed that bariatric surgery, when performed with the use of robotics, had similar or lower complication rates compared with traditional laparoscopy. Two studies showed shorter operative times using the robot for Roux-en-Y gastric bypass, but 4 studies showed longer operative times in the robotic arm. In addition, the learning curve appears to be shorter when robotic gastric bypass is compared with the traditional laparoscopic approach. Most investigators agreed that robotic laparoscopic surgery provides superior imaging and freedom of movement compared with traditional laparoscopy. The application of robotics appears to be a safe option within the realm of bariatric surgery. Prospective randomized trials comparing robotic and laparoscopic outcomes are needed to further define the role of robotics within the field of bariatric surgery. Longer follow-up times would also help elucidate any long-term outcomes differences with the use of robotics versus traditional laparoscopy.

General anesthetic and the risk of dementia in elderly patients: current insights

2014-01-01

In this review, we aim to provide clinical insights into the relationship between surgery, general anesthesia (GA), and dementia, particularly Alzheimer’s disease (AD). The pathogenesis of AD is complex, involving specific disease-linked proteins (amyloid-beta [Aβ] and tau), inflammation, and neurotransmitter dysregulation. Many points in this complex pathogenesis can potentially be influenced by both surgery and anesthetics. It has been demonstrated in some in vitro, animal, and human studies that some anesthetics are associated with increased aggregation and oligomerization of Aβ peptide and enhanced accumulation and hyperphosphorylation of tau protein. Two neurocognitive syndromes that have been studied in relation to surgery and anesthesia are postoperative delirium and postoperative cognitive dysfunction, both of which occur more commonly in older adults after surgery and anesthesia. Neither the route of anesthesia nor the type of anesthetic appears to be significantly associated with the development of postoperative delirium or postoperative cognitive dysfunction. A meta-analysis of case-control studies found no association between prior exposure to surgery utilizing GA and incident AD (pooled odds ratio =1.05, P=0.43). The few cohort studies on this topic have shown varying associations between surgery, GA, and AD, with one showing an increased risk, and another demonstrating a decreased risk. A recent randomized trial has shown that patients who received sevoflurane during spinal surgery were more likely to have progression of preexisting mild cognitive impairment compared to controls and to patients who received propofol or epidural anesthesia. Given the inconsistent evidence on the association between surgery, anesthetic type, and AD, well-designed and adequately powered studies with longer follow-up periods are required to establish a clear causal association between surgery, GA, and AD.

Bariatric surgery is increasingly being carried out and revisional procedures have also risen in concert. A review of the complications and revisions might elucidate technical and patient factors that influence the outcomes of bariatric surgeries in Asian patients. The objective of this study is to review the safety and efficacy of revisional bariatric surgery in a single center in Singapore over a 10-year period. The setting of this study is a single public hospital with a multidisciplinary bariatric service including a weight management center, specialized endocrinology services, and bariatric surgical team. Participants were selected for surgery based on body mass index (BMI) and comorbidities. All patients underwent primary laparoscopic adjustable gastric banding (LAGB). Patients were then analyzed according to the types of revisional surgeries. The primary outcome was the type of complications and revisional surgeries. Secondary outcomes include short-term excess weight loss and further complications. A total of 365 patients were analyzed. 9.6% had a secondary procedure. In particular, two groups of complications required revisional surgery: failure of sustained weight loss and complications related to the LAGB insertion and use. Revisional surgeries had equivalent major complication rates (5.7%) compared to primary bariatric surgeries (6.8%). Revisional surgeries such as revisional LAGB (4.9 ± 9.8 kg), laparoscopic sleeve gastrectomy (LSG; 6.9 ± 21.0 kg), Roux-en-Y gastric bypass (RYGB; 4.6 ± 13.0 kg), and bilio-pancreatic diversion (BPD; 3.5 ± 6.3 kg) had modest weight loss compared to primary weight loss (12.7 ± 9.5 kg). Primary LAGB had a greater percentage excess weight loss in the first and second years post-surgery compared to revisional surgeries. There was one mortality post-primary surgery and no post-revisional surgical mortalities. Revisional bariatric surgery for complications related to the primary surgery is safe but had reduced excess weight loss compared to the initial surgery.

This study aimed to assess driving reaction times (DRTs) after spinal surgery to establish a timeframe for safe resumption of driving by the patient postoperatively. The MEDLINE and Google Scholar databases were analyzed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) Statement for clinical studies that investigated changes in DRTs following cervical and lumbar spinal surgery. Changes in DRTs and patients' clinical presentation, pathology, anatomical level affected, number of spinal levels involved, type of intervention, pain level, and driving skills were assessed. The literature search identified 12 studies that investigated postoperative DRTs. Six studies met the inclusion criteria; five studies assessed changes in DRT after lumbar spine surgery and two studies after cervical spina surgery. The spinal procedures were selective nerve root block, anterior cervical discectomy and fusion, and lumbar fusion and/ordecompression. DRTs exhibited variable responses to spinal surgery and depended on the patients' clinical presentation, spinal level involved, and type of procedure performed. The evidence regarding the patients' ability to resume safe driving after spinal surgery is scarce. Normalization of DRT or a return of DRT to pre-spinal intervention level is a widely accepted indicator for safe driving, with variable levels of statistical significance owing to multiple confounding factors. Considerations of the type of spinal intervention, pain level, opioid consumption, and cognitive function should be factored in the assessment of a patient's ability to safely resume driving.

This study investigated the factors associated with variation in the rate of surgery for enthesopathy of the extensor carpi radialis brevis (eECRB). We used a large database from 3 academic hospitals including 5964 patients with the diagnosis of eECRB from 2001 to 2007. Of those, 244 patients (4%) had surgery for eECRB. We used the date of the first encounter as the date of diagnosis. We also recorded the date of the first cortisone injection and surgery for eECRB. We used Cox multivariable regression analysis to find factors associated with surgery. We considered the following explanatory factors: age, sex, race, diabetes, a diagnosis of major depression, a diagnosis of an anxiety disorder, hospital, provider (surgeon vs. nonsurgeon), corticosteroid injection, and the time from diagnosis to the first cortisone injection. The hazard ratio of having surgery was 12-times greater if the initial provider was an orthopedic surgeon rather a nonsurgeon and 1.7-times greater at 1 of the 2 hospitals. The rate of surgery varied substantially, ranging from 0% to 22%. Corticosteroid injection delayed the time to surgery but was ultimately associated with a higher rate of surgery. The majority (86%) of surgeries were done within 1 year of the first documented office visit. It seems likely that an emphasis on the preferences and values of the patient rather than the surgeon would decrease the variation in surgery rates for eECRB observed in this study. Methods for optimizing the influence of patient preferences and values on decision making (eg, decision aids) merit additional study.

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.

Musculoskeletal low back pain (LBP) is commonly treated symptomatically, with practice guidelines advocating reserving surgery for cases that fail conservative care. This study examined medical comorbidities and demographic variables as risk factors for chronic/recurrent LBP, spinal surgery, and time to surgery. A 2015 retrospective cohort study was conducted in U.S. Army soldiers (N=1,092,420) from 2002 to 2011. Soldiers with medical encounters for LBP were identified using ICD-9 codes. Surgical treatment for LBP was identified according to Current Procedural Terminology codes. Comorbid medical conditions (psychological disorders, sleep disorders, tobacco use, alcohol use, obesity) and demographic variables were examined as risk factors for chronic/recurrent LBP within 1 year of the incident encounter, surgery for LBP, and time to surgery. Of 383,586 patients with incident LBP, 104,169 (27%) were treated for chronic/recurrent LBP and 7,446 (1.9%) had surgery. Comorbid variables showed increased risk of chronic/recurrent LBP ranging from 26% to 52%. Tobacco use increased risk for surgery by 33% (risk ratio, 1.33; 95% CI=1.24, 1.44). Comorbid variables showed 10%-42% shorter time to surgery (psychological disorders, time ratio [TR]=0.90, 95% CI=0.83, 0.98; sleep disorders, TR=0.68, 95% CI=0.60, 0.78; obesity, TR=0.88, 95% CI=0.79, 0.98; tobacco use, TR=0.58, 95% CI=0.54, 0.63; alcohol use, TR=0.85, 95% CI=0.70, 1.05). Women showed 20% increased risk of chronic/recurrent LBP than men but 42% less risk of surgery. In the presence of comorbidities associated with mental health, sleep, obesity, tobacco use, and alcohol use, LBP shows increased risk of becoming chronic/recurrent and faster time to surgery.

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. Carbon dioxide insufflation during pneumoperitoneum in pediatric patients may not affect cerebral oxygenation under laparoscopic surgery. Copyright © 2015 Sociedade Brasileira de Anestesiologia.

2015-08-01

Functional endoscopic sinus surgery (FESS) was historically predicated on targeted widening of narrow anatomic structures that caused postobstructive persistent sinus inflammation. It is now clear that chronic rhinosinusitis (CRS) is a multifactorial disease with subsets of patients which may require a more extensive surgical approach. This study compares quality-of-life (QOL) and disease severity outcomes after FESS based on the extent of surgical intervention. Participants with CRS were prospectively enrolled into an ongoing, multi-institutional, observational, cohort study. Surgical extent was determined by physician discretion. Participants undergoing bilateral frontal sinusotomy, ethmoidectomy, maxillary antrostomy, and sphenoidotomy were considered to have undergone "complete" surgery, whereas all other participants were categorized as receiving "targeted" surgery. Improvement was evaluated between surgical subgroups with at least 6-month follow-up using the 22-item Sino-Nasal Outcome Test (SNOT-22) and the Brief Smell Inventory Test (B-SIT). A total of 311 participants met inclusion criteria with 147 subjects undergoing complete surgery and 164 targeted surgery. A higher prevalence of asthma, acetylsalicylic acid (ASA) sensitivity, nasal polyposis, and a history of prior sinus surgery (p ≤ 0.002) was present in participants undergoing complete surgery. Mean improvement in SNOT-22 (28.1 ± 21.9 vs 21.9 ± 20.6; p = 0.011) and B-SIT (0.8 ± 3.1 vs 0.2 ± 2.4; p = 0.005) was greater in subjects undergoing complete surgery. Regression models demonstrated a 5.9 ± 2.5 greater relative mean improvement on SNOT-22 total scores with complete surgery over targeted approaches (p = 0.016). Complete surgery was an independent predictor of greater postoperative SNOT-22 score improvement, yet did not achieve clinical significance. Further study is needed to determine the optimal surgical extent. © 2015 ARS-AAOA, LLC.

Cosmetic surgery attitudes among midlife women: Appearance esteem, weight esteem, and fear of negative appearance evaluation.

Previous research has examined factors thought to influence individuals' interest in cosmetic surgery, yet few studies have examined these issues among midlife women. This study examines predictors of cosmetic surgery attitudes among midlife women ( N = 114; age = 45-65 years; M age  = 53.7) and considers a previously unexplored variable: fear of negative appearance evaluation. Results indicated that lower weight and appearance esteem were associated with more positive cosmetic surgery attitudes and greater fear of negative appearance evaluation. Furthermore, fear of negative appearance evaluation mediated the relationship between appearance and weight esteem and cosmetic surgery attitudes. We conclude that fear of negative appearance evaluation is an important factor to consider in examining cosmetic surgery attitudes.

Postoperative pneumonia is a common complication of surgery, and is associated with marked morbidity and mortality. Despite advances in surgical and anesthetic technique, it persists as a frequent postoperative complication. Many studies have aimed to assess its burden, as well as associated risk factors. However, this complication varies among the different surgical specialties, and there is a paucity of reports that comprehensively evaluate this complication. Therefore, the purpose of this study was to review the epidemiology and risk factors of postoperative pneumonia in the setting of: 1) general surgery; 2) cardiothoracic surgery; 3) orthopedic and spine surgery; and 4) head and neck surgery.

Quality of life (QoL) is an important outcome in plastic surgery. However, authors use different scales to address this subject, making it difficult to compare the outcomes. To address this discrepancy, the aim of this study was to perform a systematic review and a random effect meta-analysis. The search was made in two electronic databases (LILACS and PUBMED) using Mesh and non-Mesh terms related to aesthetic plastic surgery and QoL. We performed qualitative and quantitative analyses of the gathered data. We calculated a random effect meta-analysis with Der Simonian and Laird as variance estimator to compare pre- and postoperative QoL standardized mean difference. To check if there is difference between aesthetic surgeries, we compared reduction mammoplasty to other aesthetic surgeries. Of 1,715 identified, 20 studies were included in the qualitative analysis and 16 went through quantitative analysis. The random effect of all aesthetic surgeries shows that QoL improved after surgery. Reduction mammoplasty has improved QoL more than other procedures in social functioning and physical functioning domains. Aesthetic plastic surgery increases QoL. Reduction mammoplasty seems to have better improvement compared with other aesthetic surgeries.

Attrition of residents from general surgery training programs is relatively high; however, there are wide discrepancies in the prevalence and causes of attrition reported among surgical residents in previous studies. To summarize the estimate of attrition prevalence among general surgery residents. We searched the Medline, EMBASE, Cochrane, PsycINFO, and ERIC databases (January 1, 1946, to October 22, 2015) for studies reporting on the prevalence and causes of attrition in surgical residents, as well as the characteristics and destinations of residents who left general surgery training programs. Database searches were conducted on October 22, 2015. Eligibility criteria included all studies reporting on the primary (attrition prevalence) or secondary (causes of attrition and characteristics and destination of residents who leave residency programs) outcomes in peer-reviewed journals. Commentaries, reviews, and studies reporting on preliminary surgery programs were excluded. Of the 41 full-text articles collected from the title/abstract screening, 22 studies (53.7%) met the selection criteria. Two reviewers independently collected and summarized the data. We calculated pooled estimates using random effects meta-analyses where appropriate. Attrition prevalence of general surgery residents. Overall, we included 22 studies that reported on residents (n = 19 821) from general surgery programs. The pooled estimate for the overall attrition prevalence among general surgery residents was 18% (95% CI, 14%-21%), with significant between-study variation (I2 = 96.8%; P < .001). Attrition was significantly higher among female compared with male (25% vs 15%, respectively; P = .008) general surgery residents, and most residents left after their first postgraduate year (48%; 95% CI, 39%-57%). Departing residents often relocated to another general surgery program (20%; 95% CI, 15%-24%) or switched to anesthesia (13%; 95% CI, 11%-16%) and other specialties. The most common reported causes of attrition were uncontrollable lifestyle (range, 12%-87.5%) and transferring to another specialty (range, 19%-38.9%). General surgery programs have relatively high attrition, with female residents more likely to leave their training programs than male residents. Residents most often relocate or switch to another specialty after the first postgraduate year owing to lifestyle-related issues.

To compare the surgical outcomes of simultaneous penetrating keratoplasty and cataract surgery with those of sequential surgery. Thirty-nine eyes of 39 patients scheduled for simultaneous keratoplasty and cataract surgery and 23 eyes of 23 patients scheduled for sequential keratoplasty and secondary phacoemulsification surgery were recruited. Refractive error, regular and irregular corneal astigmatism determined by Fourier analysis, and endothelial cell loss were studied at 1 week and 3, 6, and 12 months after combined surgery in the simultaneous surgery group or after subsequent phacoemulsification surgery in the sequential surgery group. At 3 and more months after surgery, mean refractive error was significantly greater in the simultaneous surgery group than in the sequential surgery group, although no difference was seen at 1 week. The refractive error at 12 months was within 2 D of that targeted in 15 eyes (39%) in the simultaneous surgery group and within 2 D in 16 eyes (70%) in the sequential surgery group; the incidence was significantly greater in the sequential group (P = 0.0344). The regular and irregular astigmatism was not significantly different between the groups at 3 and more months after surgery. No significant difference was also found in the percentage of endothelial cell loss between the groups. Although corneal astigmatism and endothelial cell loss were not different, refractive error from target refraction was greater after simultaneous keratoplasty and cataract surgery than after sequential surgery, indicating a better outcome after sequential surgery than after simultaneous surgery.

Osteoarthritis (OA) is the third most common diagnosis made by general practitioners in older patients. The aim of this study was to compare the function scores of different surgeries in the treatment of knee osteoarthritis (KOA). Cohort studies about different surgical treatments for KOA were included with a comprehensive search in PubMed, Cochrane Library, and Embase. The standard mean difference (SMD) value was evaluated and the surface under the cumulative ranking (SUCRA) curve was drawn with a combination of direct and indirect evidence. A total of 265 eligible patients were enrolled and served as the nonoperative treatment group, osteotomy group, unicompartmental knee arthroplasty (UKA) group, total knee arthroplasty (TKA) group, and arthroscopic surgery group. Before surgery, 6 months after surgery, 1 year after surgery and 5 years after surgery, the hospital for special surgery (HSS) knee score, Lysholm score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, and American knee society score (KSS) were recorded. A total of 9 cohort studies including 954 patients with KOA were finally enrolled into the study. The network-meta analysis revealed that osteotomy and UKA treatments showed a better efficacy on improving the function score. Our cohort study further confirmed that, a higher HSS knee score after 1 year and higher Lysholm score after 6 months and 1 year were observed in the osteotomy and UKA groups, while better HSS knee score and KSS after 6 months and 1 year were showed in the osteotomy and TKA groups. In the TKA group, Lysholm score and KSS were higher and WOMAC score was lower after 5 years than other groups. WOMAC score was lowest in the UKA group after 6 months, 1 year and 5 years of surgery. These results provide evidence that function scores of patients with KOA were improved by osteotomy, UKA, TKA, and arthroscopic surgery. And osteotomy and UKA showed better short-term efficacy, while TKA appeared better long-term efficacy.

Cosmetic result in breast cancer surgery is gaining increased interest. Currently, some 30-40% of the patients treated with breast conserving surgery (BCS) are dissatisfied with their final cosmetic result. In order to prevent disturbing breast deformity oncoplastic surgical techniques have been introduced. The extent of different levels of oncoplastic surgery incorporated in breast conserving surgery and its value with regard to cosmetic outcome, patient satisfaction and quality of life remains to be defined. The aim of this prospective cohort study is to investigate quality of life and satisfaction with cosmetic result in patients with breast cancer, undergoing standard lumpectomy versus level I or II oncoplastic breast conserving surgery. Female breast cancer patients scheduled for BCS, from 18 years of age, referred to our outpatient clinic from July 2015 are asked to participate in this study. General, oncologic and treatment information will be collected. Patient satisfaction will be scored preceding surgery, and at 1 month and 1 year follow up. Photographs of the breast will be used to score cosmetic result both by the patient, an independent expert panel and BCCT.Core software. Quality of life will be measured by using the BREAST-Q BCT, EORTC-QLQ and EQ-5D-5 L questionnaires. The purpose of this prospective study is to determine the clinical value of different levels of oncoplastic techniques in breast conserving surgery, with regard to quality of life and cosmetic result. Analysis will be carried out by objective measurements of the final cosmetic result in comparison with standard breast conserving surgery. The results of this study will be used to development of a clinical decision model to guide the use oncoplastic surgery in future BCS.

2014-12-01

Recent evidence has demonstrated a profound increase in the incidence of shoulder surgery. Superior labral anterior and posterior (SLAP) repair is a common procedure that has been noted in other studies to be increasing. The purpose of this study is to report the incidence and demographics of a single shoulder surgery code in the state of Wisconsin in order to evaluate whether it is being performed in increasing numbers relative to population. In a retrospective review of the Wisconsin Hospital Association statewide database for the years 2002-2010, we queried one ICD-9 procedure code: 81.83, other repair of shoulder (not replacement or repair of recurrent dislocation). This code was selected because it would include SLAP repair and exclude most other common shoulder surgeries. The data retrieved includes ICD-9 diagnosis codes, county of surgery, patient age, and gender. The number of surgeries performed in Wisconsin over the course of the study increased by 91.4% between 2002 and 2010, starting at 5649 in 2002 and rising to 10,812 by 2010. The incidence of surgeries increased 83.1% over this time period: from 103.8 per 100,000 in 2002 to 190.1 per 100,000 in 2010. The ratio of male to female surgeries remained nearly constant at 3:2 throughout the length of the study. The mean patient age at time of surgery increased 2.6 years, from 48.3 in 2002 to 50.9 in 2010. The increase in number of shoulder surgeries is well beyond expectations based on population growth. The relatively high percentage of females does not correspond with reported gender ratios in other studies of similar shoulder procedures. The high mean age of patients and the large number of surgeries in older patients also is concerning. More educational effort needs to be given regarding the diagnosis and treatment of common shoulder conditions.

Value of surgery in patients with negative imaging and sporadic Zollinger-Ellison syndrome.

To address the value of surgery in patients with sporadic Zollinger-Ellison syndrome (ZES) with negative imaging studies. Medical control of acid hypersecretion in patients with sporadic ZES is highly effective. This has led to these patients frequently not being sent to surgery, especially if preoperative imaging studies are negative, due, in large part, to existence of almost no data on the success of surgery in this group. Fifty-eight prospectively studied patients with sporadic ZES (17% of total studied) had negative imaging studies, and their surgical outcome was compared with 117 patients with positive imaging results. Thirty-five patients had negative imaging studies in the pre-somatostatin receptor scintigraphy (SRS) era, and 23 patients in the post-SRS era. Patients with negative imaging studies had long disease histories before surgery [mean ± SEM (from onset) = 7.9 ± 1 [range, -0.25 to 35 years]) and 25% were followed for 2 or more years from diagnosis. At surgery, gastrinoma was found in 57 of 58 patients (98%). Tumors were small (mean = 0.8 cm, 60% <1 cm). The most common primary sites were duodenal 64%, pancreatic 17%, and lymph node (10%). Fifty percent had a primary-only, 41% primary + lymph node, and 7% had liver metastases. Thirty-five of 58 patients (60%) were cured immediately postoperatively, and at last follow-up [mean = -9.4 years; range, 0.2-22 years], 27 patients (46%) remained cured. During follow-up, 3 patients died, each had liver metastases at surgery. In comparison to positive imaging patients, those with negative imaging studies had lower preoperative fasting gastrin levels; had a longer delay before surgery; more frequently had a small duodenal tumor; less frequently had a pancreatic tumor, multiple tumors, or developed a new lesion postoperatively; and had a longer survival. Sporadic ZES patients with negative imaging studies are not rare even in the post-SRS period. An experienced surgeon can find gastrinoma in almost every patient (98%) and nearly one half (46%) are cured, a rate similar to patients with positive imaging findings. Because liver metastases were found in 7%, which may have been caused by a long delay in surgery and all the disease-related deaths occurred in this group, surgery should be routinely undertaken early in ZES patients despite negative imaging studies.

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.

Surgical intervention has traditionally been reserved as the last management option for pain in chronic pancreatitis. Recently, there has been a call for surgery to be offered earlier in the disease process. The objectives of this review were to evaluate the effect of early surgery on postoperative pain, pancreatic function, and re-intervention rates in chronic pancreatitis. A systematic literature search through EMBASE, Cochrane Review, and PubMed from January 1950 to January 2014 was conducted. Citations found in relevant papers are hand-searched. Data which could be pooled were analyzed using Revman (v5.2). Risk of bias analysis was conducted. Of the 2,886 potentially eligible studies identified, 11 studies met the inclusion criteria. There was large heterogeneity in the study designs, and studies were conducted over a lengthy time span. Seven studies examined pain, three studies examined pancreatic function, and three studies examined rates of re-intervention. Meta-analysis of the three studies with comparative raw data regarding complete pain relief showed that early surgery was associated with an increased likelihood of complete postoperative pain relief (RR = 1.67, 95% CI 1.09-2.56, p = 0.02). Early surgery was also associated with reduced risk of pancreatic insufficiency and low re-intervention rates. Data from this study supports considering early surgery for pain management in patients with chronic pancreatitis, with the potential of a reduced risk of pancreatic insufficiency and the need for further intervention. Further prospective randomized studies are warranted comparing early surgery against conservative step-up approaches.

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.

Background. Because of economic reasons, day surgery rates have steadily increased in many countries and the trend is to perform around 70% of all surgical procedures as day surgery. Literature shows that postoperative pain treatment remains unfulfilled in several fields such as orthopedic and general surgery patients. In Italy, the day surgery program is not yet under governmental authority and is managed regionally by local practices. Aim. To investigate the trends in pain intensity and its relation to type of surgeries and pain therapy protocols, in postoperative patients, discharged from three different Ambulatory Surgeries located in North West Italy (Piedmont region). Method. The present study enrolled 276 patients who undergone different surgical procedures in ambulatory regimen. Patients recorded postoperative pain score twice a day, compliance with prescribed drugs, and pain related reasons for contacting the hospital. Monitoring lasted for 7 days. Results. At discharge, 72% of patients were under weak opioids, 12% interrupted the treatment due to side effects, 17% of patients required extra drugs, and 15% contacted the hospital reporting pain problems. About 50% of patients experienced moderate pain during the first day after surgery. Results from our study show that most of the patients experienced avoidable pain after discharge. PMID:28115878

Past studies utilizing resting-state functional MRI (rsfMRI), have shown that obese humans exhibit altered activity in brain areas related to reward compared to normal-weight controls. However, to what extent bariatric surgery-induced weight loss alters resting-state brain activity in obese humans is less well-studied. Thus, we measured the fractional amplitude of low-frequency fluctuations from eyes-closed, rsfMRI in obese females (n = 11, mean age = 42 years, mean BMI = 41 kg/m 2 ) in both a pre- and postprandial state at two time points: four weeks before, and four weeks after bariatric surgery. Several brain areas showed altered resting-state activity following bariatric surgery, including the putamen, insula, cingulate, thalamus and frontal regions. Activity augmented by surgery was also dependent on prandial state. For example, in the fasted state, activity in the middle frontal and pre- and postcentral gyri was found to be decreased after surgery. In the sated state, activity within the insula was increased before, but not after surgery. Collectively, our results suggest that resting-state neural functions are rapidly affected following bariatric surgery and the associated weight loss and change in diet. © 2016 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

BACKGROUND: A few studies have compared the cardiac rehabilitation (CR) outcome between those who undergo conventional on-pump bypass surgery and off-pump surgery. We compared this outcome among the patients differentiated by the On-pump and off-pump surgical procedures about cardiovascular variables and psychological status. METHODS: This longitudinal study recruited 318 and 102 consecutive patients who had undergone CABG (on-pump surgery, n = 318 and off-pump surgery, n = 102) and been referred to the CR clinic. RESULTS: The off-pump surgery patients had more improvement in their metabolic equivalents (METs) value. The physical and mental components of health-related quality of life (QOL) (based on SF-36 questionnaire) as well as depression-anxiety (based on Costello-Comrey Depression and Anxiety Scale) were notably improved in the two study groups after the CR program, while changes in the QOL components scores and also depression-anxiety score were not different between the off-pump and on-pump techniques. CONCLUSIONS: Regarding QOL and psychological status, there were no differences in the CR outcome between those who underwent off-pump bypass surgery and those who underwent on-pump surgery; nevertheless, the off-pump technique was superior to the on-pump method on METs improvement following CR.

Eighty-three patients on whom successful retinal detachment had been performed were studied to note astigmatic changes following surgery. In the majority of cases the errors following such surgery are of no great clinical importance. However, in some situations a high degree of astigmatism may be produced. This study showed that these sequelae are particularly likely after radial buckling procedures, and surgeons favouring these techniques should be aware that astigmatic errors can be induced. The astigmatic errors may persist for several years after surgery. PMID:6838807

Anesthesia and/or surgery may promote Alzheimer's disease (AD) by accelerating its neuropathogenesis. Other studies showed different findings. However, the potential sex difference among these studies has not been well considered, and it is unknown whether male or female AD patients are more vulnerable to develop postoperative cognitive dysfunction. We therefore set out to perform a proof of concept study to determine whether anesthesia and surgery can have different effects in male and female AD transgenic (Tg) mice, and in female AD Tg plus Cyclophilin D knockout (CypD KO) mice. The mice received an abdominal surgery under sevoflurane anesthesia (anesthesia/surgery). Fear Conditioning System (FCS) was used to assess the cognitive function. Hippocampal levels of synaptic marker postsynaptic density 95 (PSD-95) and synaptophysin (SVP) were measured using western blot analysis. Here we showed that the anesthesia/surgery decreased the freezing time in context test of FCS at 7 days after the anesthesia/surgery in female, but not male, mice. The anesthesia/surgery reduced hippocampus levels of synaptic marker PSD-95 and SVP in female, but not male, mice. The anesthesia/surgery induced neither reduction in freezing time in FCS nor decreased hippocampus levels of PSD-95 and SVP in the AD Tg plus CypD KO mice. These data suggest that the anesthesia/surgery induced a sex-dependent cognitive impairment and reduction in hippocampus levels of synaptic markers in AD Tg mice, potentially via a mitochondria-associated mechanism. These findings could promote clinical investigations to determine whether female AD patients are more vulnerable to the development of postoperative cognitive dysfunction.

Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome usually caused by phosphaturic mesenchymal tumors. Segmental resection has been recommended for these tumors in the bones because curettage was found to be associated with a high local recurrence rate. Navigation-assisted surgery provides radiological information to guide the surgeon during surgery. No previous study has reported on the efficacy of navigation-assisted surgery for tumors in patients with TIO. Therefore, the present study aimed to evaluate the efficacy of navigation-assisted surgery for tumors in patients with TIO. The study included seven patients with TIO who were treated between January 2003 and December 2014 at our hospital. All patients underwent surgical treatment with or without the use of a 3-dimensional (3D) fluoroscopy-based navigation system. The laboratory data and oncological outcomes were evaluated. The follow-up period was 8-128 months. The tumors were located at the femur (n = 4), ischium, spine and ilium (n = 1). Of the seven patients, five underwent navigation-assisted surgery and two underwent surgery without navigation assistance. In the two patients who underwent surgery without navigation assistance, a complete cure was not obtained and osteomalacia did not resolve. One of these two patients and the other five patients who underwent navigation-assisted surgery, one patient had incomplete resection due to massive invasion of the tumor into the spinal canal, but five patients achieved complete excision and recovered from osteomalacia. Navigation-assisted surgery using a 3D fluoroscopy-based navigation system is effective for tumors in patients with TIO.

This study examines the incidence and risk of postoperative symptomatic venous thromboembolism (VTE) after orthopaedic foot/ankle surgery. Patients that received foot/ankle surgery between 2006 and 2016 were reviewed. Inclusion criteria were surgical patients that were without coagulopathy, previous VTE, and/or using anticoagulation medications including aspirin. Age, sex, body mass index, medical comorbidities, and surgical diagnosis and procedure(s) were noted. Records were reviewed to see who developed a symptomatic VTE within 90 days from surgery. This study involved 2774 patients that received foot/ankle surgery between 2006 and 2016. Of them, 22 (0.79%) developed a VTE within 90 days from surgery. The mean age of these patients was 49.5 years. Twelve patients were male and 10 were female. Sixteen patients were obese and 6 were nonobese. Postoperative VTEs were 14 infrapopliteal deep vein thrombosis (DVT), 1 suprapopliteal DVT, and 7 pulmonary emboli. The most common surgeries involved were ankle fracture repair in 8 (0.29%), Achilles tendon repair in 2 (0.07%), ankle ligament reconstruction in 2, and hammer-toe correction in 2 patients. Obesity was predictive of a postoperative VTE to a statistically significant degree (P = .04). Age, sex, medical comorbidities, diagnosis, and type of surgery were not significantly prognostic for a postsurgical VTE (P ≥ .05). The incidence of VTE after foot/ankle surgery is low. However, obese patients are at significantly higher risk for VTE after such procedures. These findings are important when educating patients as to their risks of developing a VTE after orthopaedic foot/ankle surgery. Level III: Retrospective cohort study.

Background: Acute kidney injury is a serious complication of elective major surgery. Acute dialysis is used to support life in the most severe cases. We examined whether rates and outcomes of acute dialysis after elective major surgery have changed over time. Methods: We used data from Ontario’s universal health care databases to study all consecutive patients who had elective major surgery at 118 hospitals between 1995 and 2009. Our primary outcomes were acute dialysis within 14 days of surgery, death within 90 days of surgery and chronic dialysis for patients who did not recover kidney function. Results: A total of 552 672 patients underwent elective major surgery during the study period, 2231 of whom received acute dialysis. The incidence of acute dialysis increased steadily from 0.2% in 1995 (95% confidence interval [CI] 0.15–0.2) to 0.6% in 2009 (95% CI 0.6–0.7). This increase was primarily in cardiac and vascular surgeries. Among patients who received acute dialysis, 937 died within 90 days of surgery (42.0%, 95% CI 40.0–44.1), with no change in 90-day survival over time. Among the 1294 patients who received acute dialysis and survived beyond 90 days, 352 required chronic dialysis (27.2%, 95% CI 24.8–29.7), with no change over time. Interpretation: The use of acute dialysis after cardiac and vascular surgery has increased substantially since 1995. Studies focusing on interventions to better prevent and treat perioperative acute kidney injury are needed. PMID:22733671

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.

Gastro-oesophageal reflux disease is an important risk factor for oesophageal adenocarcinoma, but abolishing reflux through surgery has not been shown to reduce this risk. The purpose of this study is to report on adenocarcinomas occurring after previous antireflux surgery and their long-term outcome. Six hundred and forty three patients underwent surgical resection in our unit for oesophagogastric adenocarcinoma between 2000 and 2009. Nine of these had antireflux surgery a median of 6.9 (mean of 9.3) years previously. Clinical and pathological characteristics and outcome (in terms of survival) are described for this patient group. The patients who had prior antireflux surgery were compared to matched control patients for disease free survival. Disease free survival in our antireflux patients was 25.1% as compared to 72.1% in controls at 3 years. (Log rank test p=0.004). Patients who have undergone antireflux surgery for chronic gastro-oesophageal reflux disease can develop adenocarcinoma and need to be monitored closely. The outcome following surgery appears greatly worse for patients with previous antireflux surgery than age/sex/stage/treatment matched controls in this small study.

The aim of this study was to systematically review the literature on antibiotic prophylaxis in gynaecologic surgeries to prevent inflammatory complications after gynaecological operations. The study was carried out as a systematic review. Only randomised controlled trials of women undergoing gynaecological surgery were included. The Medline and the Cochrane library databases were searched from 1966 to 2016. The trials must have investigated an antibiotic intervention to prevent an inflammatory complication after gynaecological surgery. Trials were excluded if they were not randomised, uncontrolled or included obstetrical surgery. Prophylactic antibiotics prevent inflammatory complications after gynaecological surgery. Prophylactic antibiotics are more effective in surgery requiring access to the peritoneal cavity or the vagina. Cefotetan appears to be more capable in preventing the overall inflammatory complication rate than cefoxitin or cefazolin. No benefit has been shown for the combination of antibiotics as prophylaxis. No difference has been shown between the long-term and short-term use of antibiotics. There is no need for the primary use of an anaerobic antibacterial agent. Antibiotics help to prevent postoperative inflammatory complications after major gynecologic surgeries.

To systematically review early surgery and the optimal timing of surgery in patients with infective endocarditis (IE), a search for foreign and domestic articles on cohort studies about the association between early surgery and infective endocarditis published from inception to January 2015 was conducted in the PubMed, EMBASE, Chinese Biomedical Literature (CBM), Wanfang and Chinese National Knowledge Infrastructure (CNKI) databases. The studies were screened according to the inclusion and exclusion criteria, the data were extracted and the quality of the method of the included studies was assessed. Then, the meta-analysis was performed using the Stata 12.0 software. Sixteen cohort studies, including 8141 participants were finally included. The results of the meta-analysis revealed that, compared with non-early surgery, early surgery in IE lowers the incidence of in-hospital mortality [odds ratio (OR) = 0.57, 95% confidence interval (CI) (0.42, 0.77); P = 0.000, I2 = 73.1%] and long-term mortality [OR = 0.57, 95% CI (0.43, 0.77); P = 0.001, I2 = 67.4%]. Further, performing operation within 2 weeks had a more favourable effect on long-term mortality [OR = 0.63, 95% CI (0.41, 0.97); P = 0.192, I2 = 39.4%] than non-early surgery. In different kinds of IE, we found that early surgery for native valve endocarditis (NVE) had a lower in-hospital [OR = 0.46, 95% CI (0.31, 0.69); P = 0.001, I2 = 73.0%] and long-term [OR = 0.57, 95% CI (0.40, 0.81); P = 0.001, I2 = 68.9%] mortality than the non-early surgery group. However, for prosthetic valve endocarditis (PVE), in-hospital mortality did not differ significantly [OR = 0.83, 95% CI (0.65, 1.06); P = 0.413, I2 = 0.0%] between early and non-early surgery. We concluded that early surgery was associated with lower in-hospital and long-term mortality compared with non-early surgical treatment for IE, especially in NVE. However, the optimal timing of surgery remains unclear. Additional larger prospective clinical trials will be required to clarify the optimal timing for surgical intervention and determine its efficacy in PVE. PMID:26678152

Nasal airway obstruction (NAO) is a common problem that affects patient quality of life. Surgical success for NAO correction is variable. Virtual surgery planning via computational fluid dynamics (CFD) has the potential to improve the success rates of NAO surgery. To elicit surgeon feedback of a virtual surgery planning tool for NAO and to determine if this tool affects surgeon decision making. For this cross-sectional study, 60-minute face-to-face interviews with board-certified otolaryngologists were conducted at a single academic otolaryngology department from September 16, 2016, through October 7, 2016. Virtual surgery methods were introduced, and surgeons were able to interact with the virtual surgery planning tool interface. Surgeons were provided with a patient case of NAO, and open feedback of the platform was obtained, with emphasis on surgical decision making. Likert scale responses and qualitative feedback were collected for the virtual surgery planning tool and its influence on surgeon decision making. Our 9 study participants were all male, board-certified otolaryngologists with a mean (range) 15 (4-28) number of years in practice and a mean (range) number of nasal surgeries per month at 2.2 (0.0-6.0). When examined on a scale of 1 (not at all) to 5 (completely), surgeon mean (SD) score was 3.4 (0.5) for how realistic the virtual models were compared with actual surgery. On the same scale, when asked how much the virtual surgery planning tool changed surgeon decision making, mean (SD) score was 2.6 (1.6). On a scale of 1 (strongly disagree) to 7 (strongly agree), surgeon scores for perceived usefulness of the technology and attitude toward using it were 5.1 (1.1) and 5.7 (0.9), respectively. Our study shows positive surgeon experience with a virtual surgery planning tool for NAO based on CFD simulations. Surgeons felt that future applications and areas of study of the virtual surgery planning tool include its potential role for patient counseling, selecting appropriate surgical candidates, and identifying which anatomical structures should be targeted for surgical correction.

Recent attention has sought to standardize hand surgery training in the United States. This study analyzes the variability in operative hand experience for orthopedic and general surgery residents. Case logs for orthopedic and general surgery residency graduates were obtained from the American Council of Graduate Medical Education (2006-2007 to 2014-2015). Plastic surgery case logs were not available for comparison. Hand surgery case volumes were compared between specialties with parametric tests. Intraspecialty variation in orthopedic surgery was assessed between the bottom and top 10th percentiles in procedure categories. Case logs for 9605 general surgery residents and 5911 orthopedic surgery residents were analyzed. Orthopedic surgery residents performed a greater number of hand surgery cases than general surgery residents ( P < .001). Mean total hand experience ranged from 2.5 ± 4 to 2.8 ± 5 procedures for general surgery residents with no reported cases of soft tissue repairs, vascular repairs, and replants. Significant intraspecialty variation existed in orthopedic surgery for all hand procedure categories (range, 3.3-15.0). As the model for hand surgery training evolves, general surgeons may represent an underutilized talent pool to meet the critical demand for hand surgeon specialists. Future research is needed to determine acceptable levels of training variability in hand surgery.

Introduction Increasing numbers of women are seeking labial reduction surgery. We studied the motivations for considering labial reduction surgery as recounted on women's online communities and surgery provider's websites. Aims The study analyzed motivations for considering labial reduction surgery expressed by women on online communities, looked at the role of the women's age and nationality, compared findings with motivations indicated on the websites of an international sample of surgery providers, and identified similarities to and differences from what is known from extant studies. Methods Quantitative content analysis of the posts of 78 American, British, and Dutch women on online communities, and 40 international surgery providers' websites about labial reduction surgery was conducted. Main Outcome Measures Main outcome measures concerned the incidence and prominence of different motivational categories (functional/emotional and discomfort/enhancement related). Differences in motivations as a function of age, national background, and women's vs. surgeons' stated motivations were tested. Results Emotional discomfort regarding self-appearance and social and sexual relationships was found to be the most frequent and most prominent motivation for considering labial reduction surgery on women's online communities, regardless of age and national background. Functional discomfort and desired emotional enhancement ranked second. Very few age or national differences were found. The surgeons' websites recognized functional discomfort more and elaborated upon emotional issues in sexual relationships less than members of the online communities. Conclusions Feelings of emotional and psychosexual distress in addition to functional distress are a highly prevalent motivation among women considering labial reduction surgery. Emotional distress appears to be greater and more freely emphasized when women communicate on online communities, while functional issues appear to receive greater notice on surgery provider's websites.

The objective of this study was to examine both overall and disease-free survival of patients with advanced stage ovarian cancer after immediate or interval debulking surgery based on residual disease. We performed a retrospective chart review at the Tom Baker Cancer Centre in Calgary, Alberta of patients with pathologically confirmed stage III or IV ovarian cancer, fallopian tube cancer, or primary peritoneal cancer between 2003 and 2007. We collected data on the dates of diagnosis, recurrence, and death; cancer stage and grade, patients' age, surgery performed, and residual disease. One hundred ninety-two patients were included in the final analysis. The optimal debulking rate with immediate surgery was 64.8%, and with interval surgery it was 85.9%. There were improved overall and disease-free survival rates for optimally debulked disease (< 1 cm) with both immediate and interval surgery (P < 0.001) compared to suboptimally debulked disease. Overall survival rates for optimally debulked disease were not significantly different in patients having immediate and interval surgery (P = 0.25). In the immediate surgery group, patients with microscopic residual disease had better disease-free survival (P = 0.015) and overall survival (P = 0.005) than patients with < 1 cm residual disease. In patients who had interval surgery, those who had microscopic residual disease had more improved disease-free survival than those with < 1 cm disease (P = 0.05), but they did not have more improved overall survival (P = 0.42). Patients with microscopic residual disease who had immediate surgery had a significantly better overall survival rate than those who had interval surgery (P = 0.034). In women with advanced stage ovarian cancer, the goal of surgery should be resection of disease to microscopic residual at the initial procedure. This results in improved overall survival than lesser degrees of resection. Further studies are required to determine optimal surgical management.

Retrospective cohort study using National inpatient sample administrative data. To determine national estimates of visual impairment and ischemic optic neuropathy after spine surgery. Loss of vision after spine surgery is rare but has devastating complications that has gained increasing recognition in the recent literature. National population-based studies of visual complications after spine surgery are lacking. All patients from 1993 to 2002 who underwent spine surgery (Clinical Classifications software procedure code: 3, 158) and who had ischemic optic neuropathy (ION) (ICD9-CM code 377.41), central retinal artery occlusion (CRAO) (ICD9-CM code 362.31) or non-ION, non-CRAO perioperative visual impairment (ICD9-CM codes: 369, 368.4, 368.8-9368.11-13) were included. Univariate and multivariate analysis were performed to identify potential risk factors. The overall incidence of visual disturbance after spine surgery was 0.094%. Spine surgery for scoliosis correction and posterior lumbar fusion had the highest rates of postoperative visual loss of 0.28% and 0.14% respectively. Pediatric patients (<18 years) were 5.8 times and elderly patients (>84 years) were 3.2 times more likely than, patients 18 to 44 years of age to develop non-ION, non-CRAO visual loss after spine surgery. Patients with peripheral vascular disease (OR = 2.0), hypertension (OR = 1.3), and those who received blood transfusion (OR = 2.2) were more likely to develop non-ION, non-CRAO vision loss after spine surgery. Ischemic optic neuropathy was present in 0.006% of patients. Hypotension (OR = 10.1), peripheral vascular disease (OR = 6.3) and anemia (OR = 5.9) were the strongest risk factors identified for the development of ION. We used multivariate analysis to identify significant risk factors for visual loss after spine surgery. National population-based estimate of visual impairment after spine surgery confirms that ophthalmic complications after spine surgery are rare. Since visual loss may be reversible in the early stages, awareness, evaluation and prompt management of this rare but potentially devastating complication is critical.

To describe the use of antibiotics for urinary tract infection (UTI) before and after surgery for urinary incontinence (UI); and for those with use of antibiotics before surgery, to estimate the risk of treatment for a postoperative UTI, relative to those without use of antibiotics before surgery. A historical population-based cohort study. Denmark. Women (age ≥18 years) with a primary surgical procedure for UI from the county of Funen and the Region of Southern Denmark from 1996 throughout 2010. Data on redeemed prescriptions of antibiotics ±365 days from the date of surgery were extracted from a prescription database. Use of antibiotics for UTI in relation to UI surgery, and the risk of being a postoperative user of antibiotics for UTI among preoperative users. A total of 2151 women had a primary surgical procedure for UI; of these 496 (23.1%) were preoperative users of antibiotics for UTI. Among preoperative users, 129 (26%) and 215 (43.3%) also redeemed prescriptions of antibiotics for UTI within 0-60 and 61-365 days after surgery, respectively. Among preoperative non-users, 182 (11.0%) and 235 (14.2%) redeemed prescriptions within 0-60 and 61-365 days after surgery, respectively. Presurgery exposure to antibiotics for UTI was a strong risk factor for postoperative treatment for UTI, both within 0-60 days (adjusted OR, aOR=2.6 (95% CI 2.0 to 3.5)) and within 61-365 days (aOR=4.5 (95% CI 3.5 to 5.7)). 1 in 4 women undergoing surgery for UI was treated for UTI before surgery, and half of them had a continuing tendency to UTIs after surgery. Use of antibiotics for UTI before surgery was a strong risk factor for antibiotic use after surgery. In women not using antibiotics for UTI before surgery only a minor proportion initiated use after surgery.

Racial and Ethnic Diversity of U.S. Plastic Surgery Trainees.

Silvestre, Jason; Serletti, Joseph M; Chang, Benjamin

Increased diversity of U.S. physicians can improve patient communication and mitigate health disparities for racial minorities. This study analyzes trends in racial and ethnic diversity of plastic surgery residents. Demographic data of surgical residents, medical students, and integrated plastic surgery residency applicants were obtained from the Association of American Medical Colleges. Data for college students and the general population were obtained from the U.S. Census for comparison with plastic surgery. Interspecialty differences and temporal trends in racial composition were analyzed with chi-square tests. From 1995 to 2014, Asian and Hispanic plastic surgery residents increased nearly 3-fold (7.4%-21.7%, p < 0.001) and 2-fold (4.6%-7.9%, p < 0.001), respectively. African American plastic surgery residents did not increase significantly (3.0%-3.5%, p = 0.129). Relative to the U.S. population, Hispanics (range: 0.1-0.5-fold) and African Americans (range: 0.1-0.4-fold) were underrepresented, whereas Asians (range: 2.2-5.3-fold) were overrepresented in plastic surgery. A "bottleneck" existed in the pipeline of African American and Hispanic plastic surgery residents. Significant differences in racial composition existed between plastic surgery and other surgical disciplines, which varied over time. The percentage of Hispanic (10.6% vs 7.0%, p = 0.402) and African American (6.4% vs 2.1%, p < 0.001) plastic surgery residency applicants exceeded those in residency. Hispanics and African Americans are underrepresented in plastic surgery residency relative to whites and Asians. This study underscores the need for greater initiatives to increase diversity in plastic surgery residency. Copyright © 2016 Association of Program Directors in Surgery. Published by Elsevier Inc.

We studied patients who had experienced a stroke in the postoperative period of cardiac surgery, aiming to analyse their progression and determine the factors that may influence prognosis and treatment. We established a protocol for early detection of stroke after cardiac surgery and collected data on stroke onset and a number of clinical, surgical, and prognostic variables in order to perform a descriptive analysis. Over the 15-month study period we recorded 16 strokes, which represent 2.5% of the patients who underwent cardiac surgery. Mean age in our sample was 69 ± 8 years; 63% of patients were men. The incidence of stroke in patients aged 80 and older was 5.1%. Five patients (31%) underwent emergency surgery. By type of cardiac surgery, 7% of patients underwent mitral valve surgery, 6.5% combined surgery, 3% aortic valve surgery, and 2.24% coronary surgery. Most cases of stroke (44%) were due to embolism, followed by hypoperfusion (25%). Stroke occurred within 2 days of surgery in 69% of cases. The mean NIHSS score in our sample of stroke patients was 9; code stroke was activated in 10 cases (62%); one patient (14%) underwent thrombectomy. Most patients progressed favourably: 13 (80%) scored≤2 on the modified Rankin Scale at 3 months. None of the patients died during the postoperative hospital stay. In our setting, strokes occurring after cardiac surgery are usually small and have a good long-term prognosis. Most of them occur within 2 days, and they are mostly embolic in origin. The incidence of stroke in patients aged 80 and older and undergoing cardiac surgery is twice as high as that of the general population. Copyright © 2017 Sociedad Española de Neurología.

Rodrigues, Maria A; Tedesco, Ana C B; Nahas, Fabio X; Ferreira, Lydia M

2014-06-01

The aim of this study was to assess the correlation between impact factor and the level of evidence of articles in plastic surgery journals. The four plastic surgery journals with the top impact factors in 2011 were selected. Articles were selected using the PubMed database between January 1 and December 31, 2011. The journal evidence index was calculated by dividing the number of randomized clinical trials by the total number of articles published in the specific journal, multiplied by 100. This index was correlated to the impact factor of the journal and compared with the average of the other journals. Two investigators independently evaluated each journal, followed by a consensus and assessment of the interexaminer concordance. The kappa test was used to evaluate the concordance between the two investigators and Fisher's exact test was used to evaluate which journal presented the highest number of randomized clinical trials. The journal evidence index values were as follows: Plastic and Reconstructive Surgery, 1.70; Journal of Plastic, Reconstructive and Aesthetic Surgery, 0.40; Aesthetic Plastic Surgery, 0.56; and Annals of Plastic Surgery, 0.35. The impact factors of these journals in 2011 were as follows: Plastic and Reconstructive Surgery, 3.382; Journal of Plastic, Reconstructive and Aesthetic Surgery, 1.494; Aesthetic Plastic Surgery, 1.407; and Annals of Plastic Surgery, 1.318. After consensus, the quantity of adequate studies was low and similar between these journals; only the journal Plastic and Reconstructive Surgery showed a higher journal evidence index. The journal Plastic and Reconstructive Surgery exhibited the highest journal evidence index and had the highest impact factor. The number of adequate articles was low in all of the assessed journals.

It has been proven that bariatric surgery affects weight loss. Patients with morbid obesity have a significantly lower quality of life (QOL) and body image compared with the general population. To evaluate QOL, body image, and general self-efficacy (GSE) in patients with morbid obesity undergoing bariatric surgery within clinical parameters. Monocentric, prospective, longitudinal cohort study. Patients completed the short form 36 (SF-36) for QOL, body image questionnaire, and GSE scale 3 times: before surgery and within 6 months and 24 months after surgery. Influence of gender, age, and type of procedure, either laparoscopic sleeve gastrectomy (SG) or laparoscopic Roux-en-Y gastric bypass, were analyzed. Thirty patients completed the questionnaires before and within 6 and 24 months after surgery. SF-36 physical summary score improved significantly from 34.3±11.0 before surgery to 46.0±10.4 within 6 months (P<.001) and to 49.8±8.2 within 24 months (P<.001) after surgery. SF-36 mental summary score improved significantly from 42.1±14.7 before surgery to 52.3±8.4 within 6 months (P<.001) and to 48.4±12.2 within 24 months (P<.001) after surgery. There were no significant differences between gender, age, and type of operation. Body image and GSE improved significantly after bariatric surgery (P<.001), and both correlated to the SF-36 mental summary score. QOL, body image, and GSE improved significantly within 6 months and remained stable within 24 months after bariatric surgery. Improvements were independent of gender, age, and type of operation. Mental QOL was influenced by body image and GSE. Copyright © 2017 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.

Intestinal fatty acid-binding protein (I-FABP) is increasingly employed as a highly specific marker of intestinal necrosis. However, the value of this marker associated with cardiovascular surgery with hypothermic circulatory arrest is unclear. The aim of this study was to measure serum I-FABP levels and provide the transition of I-FABP levels with hypothermic circulatory arrest to help in the management of intestinal perfusion. From August 2011 to September 2013, 33 consecutive patients who had aortic arch surgery with hypothermic circulatory arrest or heart valve surgery performed were enrolled in the study. Twenty patients had aortic surgery with hypothermic (23-29°C) circulatory arrest and 13 patients had heart valve surgery with cardiopulmonary bypass (33°C). I-FABP levels increased, both in patients undergoing aortic surgery with hypothermic circulatory arrest and heart valve surgery with cardiopulmonary bypass, reaching peak levels shortly after the administration of protamine. I-FABP levels in patients with aortic surgery were significantly higher with circulatory arrest. They reached peak levels immediately after recirculation and there was a significant drop at the end of surgery (p<0.001). I-FABP levels in heart valve surgery were gradually increased, with the highest at the administration of protamine; they gradually decreased. Peak I-FABP levels were significantly higher in patients undergoing aortic surgery with hypothermic circulatory arrest than in patients with heart valve surgery. However, no postoperative reperfusion injury occurred in the intestinal tract due to the use of hypothermic organ protection. Plasma I-FABP monitoring could be a valuable method for finding an intestinal ischemia in patients with cardiovascular surgery.

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.

The first aim of our study was to evaluate surgical decision-making by BRCA mutation carriers with breast cancer based on the timing of knowledge of their BRCA mutation status. The second aim was to evaluate breast cancer outcome following surgical treatment. This was a retrospective study of 164 patients diagnosed with invasive breast cancer, tested for BRCA mutation, and treated with primary surgery between 2004 and 2015 at Samsung Medical Center in Seoul, Korea. We reviewed types of surgery and timing of the BRCA test result. We compared surgical decision- making of BRCA carriers with breast cancer based on the timing of knowledge of their BRCA mutation status. Only 15 (9.1%) patients knew their BRCA test results before their surgery, and 149 (90.9%) knew the results after surgery. In patients with unilateral cancer, there was a significant difference between groups whose BRCA mutation status known before surgery and groups whose BRCA status unknown before surgery regarding the choice of surgery (p = 0.017). No significant difference was observed across surgery types of risk of ipsilateral breast tumor recurrence (p = 0.765) and contralateral breast cancer (p = 0.69). Genetic diagnosis before surgery has an impact on surgical decision choosing unilateral mastectomy or bilateral mastectomy in BRCA mutation carriers with breast cancer. Knowledge about BRCA mutation status after initial surgery led to additional surgeries for patients with BCS. Thus, providing genetic counseling and genetic testing before surgical choice and developing treatment strategies for patients with a high risk of breast cancer are important.

This study aimed to determine the effect of gum chewing on the reduction of postoperative ileus and recovery after surgery. This study was conducted a randomized controlled trial in 60 patients who underwent colorectal surgery between November 2011 and December 2012. Patients in the experimental group chewed gum three times a day. The time of flatus and defecation, the time to start feeding, pain levels and time of discharge were monitored. Post-surgery results for gum-chewing were first flatus and defecation times and the time to start feeding was shorter; pain levels were lower on the 3rd - 5th days; patients were discharged in a shorter time post-surgery. Chewing gum is a simple intervention for reducing postoperative ileus after colorectal surgery. Further studies that examine the effectiveness of gum chewing on other surgical interventions in which the development risk of postoperative ileus should be performed. Copyright © 2016 Elsevier Ltd.

Previous studies approach surgery scheduling mainly from the mathematical modeling perspective which is often hard to apply in a practical environment. The aim of this study is to develop a practical scheduling system that considers the advantages of both surgery categorization and newsvendor model to surgery scheduling. The research was carried out in a Finnish orthopaedic specialist centre that performs only joint replacement surgery. Four surgery categorization scenarios were defined and their productivity analyzed by simulation and newsvendor model. Detailed analyses of surgery durations and the use of more accurate case categories and their combinations in scheduling improved OR productivity 11.3 percent when compared to the base case. Planning to have one OR team to work longer led to remarkable decrease in scheduling inefficiency. In surgical services, productivity and cost-efficiency can be improved by utilizing historical data in case scheduling and by increasing flexibility in personnel management. The study increases the understanding of practical scheduling methods used to improve efficiency in surgical services.

Evidence and evidence gaps of laryngeal cancer surgery

PubMed Central

Wiegand, Susanne

2016-01-01

Surgical treatment of laryngeal cancer has been established for decades. In addition to total laryngectomy, which was first performed in 1873, a large number or organ preservation surgical techniques, like open partial laryngectomy, transoral laser microsurgery, and transoral robotic surgery have been developed. Studies on laryngeal cancer surgery are mainly retrospective case series and cohort studies. The evolution of chemoradiation protocols and their analysis in prospective randomized trials have led to an increasing acceptance of non-surgical treatment procedures. In addition to an improvement of prognosis, in recent years the preservation of function and maintenance of life quality after primary therapy of laryngeal cancer has increasingly become the focus of therapy planning. Significant late toxicity after chemoradiation has been identified as an important issue. This leads to a reassessment of surgical concepts and initiation of studies on laryngeal cancer surgery which was additionally stimulated by the advent of transoral robotic surgery in the US. Improving the evidence base of laryngeal cancer surgery by successful establishment of surgical trials should be the future goal. PMID:28025603

The aim of the study was to assess the risk of surgery after initial conservative treatment of rectosigmoid endometriosis in relation to demographic data. The study was conducted on the tertiary endometriosis referral unit, Aarhus University Hospital. Medical records, from patients seen from January 2009 onwards with a diagnosis of rectosigmoid endometriosis and more than 6 months' follow up were audited. Demographic data, results of magnetic resonance imaging and time to secondary surgery for rectosigmoid endometriosis were registered. Data on 238 patients diagnosed with rectosigmoid endometriosis were included. In all, 78 (32.8%) patients had primary surgery, 27 (11.3%) had secondary surgery and 133 (55.9%) continued conservative treatment throughout the observation period. Patients who underwent primary or secondary surgery were younger than patients continuing conservative treatment. In a tertiary referral center where about half of patients with rectosigmoid endometriosis were scheduled for conservative treatment, more than 80% of these avoided surgery. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

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.

Despite many publications reporting on the increased hospital cost of robotic-assisted surgery (RAS) compared to direct manual laparoscopic surgery (DMLS) and open surgery (OS), the reported health economic studies lack details on clinical outcome, precluding valid health technology assessment (HTA). The present prospective study reports total cost analysis on 699 patients undergoing general surgical, gynecological and thoracic operations between 2011 and 2014 in the Italian Public Health Service, during which period eight major teaching hospitals treated the patients. The study compared total healthcare costs of RAS, DMLS and OS based on prospectively collected data on patient outcome in addition to healthcare costs incurred by the three approaches. The cost of RAS operations was significantly higher than that of OS and DMLS for both gynecological and thoracic operations (p < 0.001). The study showed no significant difference in total costs between OS and DMLS. Total costs of general surgery RAS were significantly higher than those of OS (p < 0.001), but not against DMLS general surgery. Indirect costs were significantly lower in RAS compared to both DMLS general surgery and OS gynecological surgery due to the shorter length of hospital stay of RAS approach (p < 0.001). Additionally, in all specialties compared to OS, patients treated by RAS experienced a quicker recovery and significantly less pain during the hospitalization and after discharge. The present HTA while confirming higher total healthcare costs for RAS operations identified significant clinical benefits which may justify the increased expenditure incurred by this approach.

To determine the effects of bariatric surgery on albuminuria in obese patients with type 2 diabetes mellitus. Retrospective analyses of clinical records of obese patients with type 2 diabetes mellitus who had either micro- or macroalbuminuria and had undergone various bariatric surgery were retrieved from a local hospital database. Their clinical data from follow-up appointments including albuminuria were analysed. Of the 46 subjects with type 2 diabetes mellitus, 15 subjects had diabetic nephropathy and had pre- and post-bariatric surgery urine albumin-to-creatinine ratio or urine protein-to-creatinine ratio data available for analysis; 13 out of the 15 subjects (86.7%) showed improvement of urine albumin-to-creatinine ratio or urine protein-to-creatinine ratio after surgery; 2 showed equivocal results; 9 of 13 subjects (69.2%) showed remission of diabetic nephropathy; 7 of these 9 patients had microalbuminuria before surgery, 2 had macroalbuminuria before surgery. There were significant improvements to glycosylated haemoglobin, fasting plasma glucose, blood pressure and body weight post surgery. The usage of insulin and oral medications dropped significantly post surgery for all subjects. This study shows that bariatric surgery significantly improves diabetic nephropathy in obese type 2 diabetes mellitus subjects. The results suggest that in our local type 2 diabetes mellitus patients, it is possible not only to improve metabolic parameters, but also to reverse what may be considered established microvascular complications by means of bariatric surgery.

Organ-space surgical site infections (SSI) are the most serious and costly infections after colorectal surgery. Most previous studies of risk factors for SSI have analysed colon and rectal procedures together. The aim of the study was to determine whether colon and rectal procedures have different risk factors and outcomes for organ-space SSI. A multicentre observational prospective cohort study of adults undergoing elective colon and rectal procedures at 10 Spanish hospitals from 2011 to 2014. Patients were followed up until 30 days post-surgery. Surgical site infection was defined according to the Centers for Disease Control and Prevention criteria. Oral antibiotic prophylaxis (OAP) was considered as the administration of oral antibiotics the day before surgery combined with systemic intravenous antibiotic prophylaxis. Of 3,701 patients, 2,518 (68%) underwent colon surgery and 1,183 (32%) rectal surgery. In colon surgery, the overall SSI rate was 16.4% and the organ-space SSI rate was 7.9%, while in rectal surgery the rates were 21.6% and 11.5% respectively ( p  < 0.001). Independent risk factors for organ-space SSI in colon surgery were male sex (Odds ratio -OR-: 1.57, 95% CI: 1.14-2.15) and ostomy creation (OR: 2.65, 95% CI: 1.8-3.92) while laparoscopy (OR: 0.5, 95% CI: 0.38-0.69) and OAP combined with intravenous antibiotic prophylaxis (OR: 0.7, 95% CI: 0.51-0.97) were protective factors. In rectal surgery, independent risk factors for organ-space SSI were male sex (OR: 2.11, 95% CI: 1.34-3.31) and longer surgery (OR: 1.49, 95% CI: 1.03-2.15), whereas OAP with intravenous antibiotic prophylaxis (OR: 0.49, 95% CI: 0.32-0.73) was a protective factor. Among patients with organ-space SSI, we found a significant difference in the overall 30-day mortality, being higher in colon surgery than in rectal surgery (11.5% vs 5.1%, p  = 0.04). Organ-space SSI in colon and rectal surgery has some differences in terms of incidence, risk factors and outcomes. These differences could be considered for surveillance purposes and for the implementation of preventive strategies. Administration of OAP would be an important measure to reduce the OS-SSI rate in both colon and rectal surgeries.

The purpose of the study is to evaluate those cases of pterygium surgery with fibrin sealant that produced dehiscence of the graft, and then apply and evaluate the efficacy of a different surgical technique in an attempt eliminate this complication in previously identified cases of high risk. The first phase is a retrospective study of 42 cases of pterygium surgery. In the second phase, the variation in the surgical technique was prospectively used in 14 cases of pterygium surgery. Cases of recurrent pterygium, broad pterygium, and complicated surgery were identified as the groups with a risk of suffering dehiscence of the graft. With the variant applied surgery no dehiscence occurred when using the variation in surgical technique, with no added complications. Copyright © 2012 Sociedad Española de Oftalmología.

This is a qualitative study designed to examine patient acceptability of re-sampling surgery for glioblastoma multiforme (GBM) electively post-therapy or at asymptomatic relapse. Thirty patients were selected using the convenience sampling method and interviewed. Patients were presented with hypothetical scenarios including a scenario in which the surgery was offered to them routinely and a scenario in which the surgery was in a clinical trial. The results of the study suggest that about two thirds of the patients offered the surgery on a routine basis would be interested, and half of the patients would agree to the surgery as part of a clinical trial. Several overarching themes emerged, some of which include: patients expressed ethical concerns about offering financial incentives or compensation to the patients or surgeons involved in the study; patients were concerned about appropriate communication and full disclosure about the procedures involved, the legalities of tumor ownership and the use of the tumor post-surgery; patients may feel alone or vulnerable when they are approached about the surgery; patients and their families expressed immense trust in their surgeon and indicated that this trust is a major determinant of their agreeing to surgery. The overall positive response to re-sampling surgery suggests that this procedure, if designed with all the ethical concerns attended to, would be welcomed by most patients. This approach of asking patients beforehand if a treatment innovation is acceptable would appear to be more practical and ethically desirable than previous practice.

Population-based studies evaluating outcomes of different approaches for rectal cancer are scarce. We conducted a retrospective cohort study using the Nationwide Inpatient Sample database between 2008 and 2012. We compared the outcomes and costs among rectal cancer patients undergoing robotic, laparoscopic, or open surgeries using propensity scores for adjusted and matched analysis. We identified 194 957 rectal cancer patients. Over the 5-year period, the annual admission number decreased by 13.9%, the in-hospital mortality rate decreased by 32.2%, while the total hospitalization cost increased by 13.6%. Compared with laparoscopic surgery, robotic surgery had significantly lower length of stay (LOS) (OR 0.69, 95%CI 0.57-0.84), comparable wound complications (OR 1.08, 95%CI 0.70-1.65) and higher cost (OR 1.42, 95%CI 1.13-1.79), while open surgery had significantly longer LOS (OR 1.38, 95%CI 1.19-1.59), more wound complications (OR 1.49, 95%CI 1.08-1.79), and comparable cost (OR 0.92, 95%CI 0.79-1.07). There were no difference in in-hospital mortality among three approaches. Laparoscopic surgery was associated with better outcomes than open surgery. Robotic surgery was associated with higher cost, but no advantage over laparoscopic surgery in terms of mortality and complications. Studies on cost-effectiveness of robotic surgery may be warranted. © 2017 Wiley Periodicals, Inc.

Depressive symptoms have been reported as prevalent after bariatric surgery. This study aims to analyze the role of weight, eating behaviors and body image in depressive symptomatology in bariatric surgery patients assessed post-operatively. This is a cross-sectional study including 52 bariatric surgery patients assessed post-operatively with a follow-up time ranging from 22 to 132 months. Psychological assessment included a clinical interview (Eating Disorder Examination) to assess eating disorders psychopathology, and three self-report measures: Outcome Questionnaire 45--general distress; Beck Depression Inventory--depressive symptoms; and Body Shape Questionnaire--body image. Our data show that depressive symptoms after surgery are associated with loss of control over eating, increased concerns with body image, and body mass index regain. Multiple linear regressions was tested including these variables and showed that body mass index regain after surgery, loss of control over eating and concerns with body image significantly explained 50% of the variance of post-operative depressive symptoms, being the concern with body image the most significant variable: greater dissatisfaction with body image was associated with more depressive symptoms. The results of this study showed that a subgroup of patients presents a significant weight gain after bariatric surgery, which is associated with episodes of loss of control over eating, concerns with body image and depressive symptoms. These results stress the relevance of body image concerns after surgery and the importance of clinically addressing these issues to optimize psychological functioning after bariatric surgery.

To describe a new surgical procedure for pelvic organ prolapse using mesh and a vaginal support device (VSD) and to report the results of surgery. A prospective observational study. Two tertiary referral Urogynaecology practices. Ninety-five women with International Continence Society pelvic organ prolapse quantification stage 2 or more pelvic organ prolapse who underwent vaginal surgery using mesh augmentation and a VSD. Surgery involved a vaginal approach with mesh reinforcement and placement of a VSD for 4 weeks. At 6 and 12 months, women were examined for prolapse recurrence, and visual analogue scales for satisfaction were completed. Women completed quality-of-life (QOL) questionnaires preoperatively and at 6 and 12 months. Objective success of surgery at 6 and 12 months following surgery. Secondary outcomes were subjective success, complications, QOL outcomes and patients' satisfaction. Objective success rate was 92 and 85% at 6 and 12 months, respectively. Subjective success rate was 91 and 87% at 6 and 12 months, respectively. New prolapse in nonrepaired compartments accounted for 7 of 12 (58%) failures at 12 months. Two of 4 mesh exposures required surgery. Sexual dysfunction was reported by 58% of sexually active women preoperatively and 23% at 12 months. QOL scores significantly improved at 12 months compared with baseline (P < 0.0001). Vaginal surgery using mesh and a VSD is an effective procedure for pelvic organ prolapse. However, further studies are required to establish the role of the surgery described in this study.

The use of limited transthoracic echocardiography (TTE) has been restricted in patients after cardiac surgery due to reported poor image quality. The authors hypothesized that the hemodynamic state could be evaluated in a high proportion of patients at repeated intervals after cardiac surgery. Prospective observational study. Tertiary university hospital. The study comprised 51 patients aged 18 years or older presenting for cardiac surgery. Patients underwent TTE before surgery and at 3 time points after cardiac surgery. Images were assessed offline using an image quality scoring system by 2 expert observers. Hemodynamic state was assessed using the iHeartScan protocol, and the primary endpoint was the proportion of limited TTE studies in which the hemodynamic state was interpretable at each of the 3 postoperative time points. Hemodynamic state interpretability varied over time and was highest before surgery (90%) and lowest on the first postoperative day (49%) (p<0.01). This variation in interpretability over time was reflected in all 3 transthoracic windows, ranging from 43% to 80% before surgery and from 2% to 35% on the first postoperative day (p<0.01). Image quality scores were highest with the apical window, ranging from 53% to 77% across time points, and lowest with the subcostal window, ranging from 4% to 70% across time points (p< 0.01). Hemodynamic state can be determined with TTE in a high proportion of cardiac surgery patients after extubation and removal of surgical drains. Copyright © 2017 Elsevier Inc. All rights reserved.

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.

To systematically review early surgery and the optimal timing of surgery in patients with infective endocarditis (IE), a search for foreign and domestic articles on cohort studies about the association between early surgery and infective endocarditis published from inception to January 2015 was conducted in the PubMed, EMBASE, Chinese Biomedical Literature (CBM), Wanfang and Chinese National Knowledge Infrastructure (CNKI) databases. The studies were screened according to the inclusion and exclusion criteria, the data were extracted and the quality of the method of the included studies was assessed. Then, the meta-analysis was performed using the Stata 12.0 software. Sixteen cohort studies, including 8141 participants were finally included. The results of the meta-analysis revealed that, compared with non-early surgery, early surgery in IE lowers the incidence of in-hospital mortality [odds ratio (OR) = 0.57, 95% confidence interval (CI) (0.42, 0.77); P = 0.000, I(2) = 73.1%] and long-term mortality [OR = 0.57, 95% CI (0.43, 0.77); P = 0.001, I(2) = 67.4%]. Further, performing operation within 2 weeks had a more favourable effect on long-term mortality [OR = 0.63, 95% CI (0.41, 0.97); P = 0.192, I(2) = 39.4%] than non-early surgery. In different kinds of IE, we found that early surgery for native valve endocarditis (NVE) had a lower in-hospital [OR = 0.46, 95% CI (0.31, 0.69); P = 0.001, I(2) = 73.0%] and long-term [OR = 0.57, 95% CI (0.40, 0.81); P = 0.001, I(2) = 68.9%] mortality than the non-early surgery group. However, for prosthetic valve endocarditis (PVE), in-hospital mortality did not differ significantly [OR = 0.83, 95% CI (0.65, 1.06); P = 0.413, I(2) = 0.0%] between early and non-early surgery. We concluded that early surgery was associated with lower in-hospital and long-term mortality compared with non-early surgical treatment for IE, especially in NVE. However, the optimal timing of surgery remains unclear. Additional larger prospective clinical trials will be required to clarify the optimal timing for surgical intervention and determine its efficacy in PVE. © The Author 2015.

Fung, Michael; Wharton, Sean; Macpherson, Alison

2016-01-01

Objectives. Bariatric surgery has been shown to be an effective intervention for weight loss and diabetes management. Despite this, many patients qualified for bariatric surgery are not interested in undergoing the procedure. The objective of this study is to determine the factors influencing receptivity to bariatric surgery among those who qualify for the procedure. Methods. Patients attending a publicly funded weight management clinic who qualified for bariatric surgery were asked to complete an elective questionnaire between February 2013 and April 2014. Results. A total of 371 patients (72% female) completed the questionnaire. Only 87 of 371 (23%) participants were interested in bariatric surgery. Individuals interested in bariatric surgery had a higher BMI (48.0 versus 46.2 kg/m2, P = 0.03) and believed that they would lose more weight with surgery (51 versus 44 kg, P = 0.0069). Those who scored highly on past weight loss success and financial concerns were less likely to be interested in bariatric surgery, whereas those who scored highly on high receptivity to surgery and positive social support were more likely to be interested in bariatric surgery. Conclusion. Although participants overestimated the effect of bariatric surgery on weight loss, most were still not interested in bariatric surgery. PMID:27516900

Surgery for trigger finger.

2018-02-20

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.

Acute pancreatitis is a possible complication after scoliosis surgery. Although some risk factors have been documented in the literature, clinical description of pancreatitis diagnosis and ensuing course still remain very poor. The aim of this study was to describe characteristics of acute pancreatitis after scoliosis surgery. A descriptive, retrospective and single-center study of fourteen adolescents with postoperative acute pancreatitis after spine fusion surgery in scoliosis management between April 2003 and August 2012 was performed. Acute pancreatitis occurred within 9.5 days (4-51) after surgery. Abdominal pain was atypical and was expressed in only half of the children. Ileus, nausea and vomiting were the most frequent signs. None of the acute pancreatitis cases was severe. Acute pancreatitis is an early complication of scoliosis surgery. Clinical signs are atypical and non-severe and can induce misleading forms. Presence of delayed digestive problems should alert the clinician to the risk of pancreatitis in the aftermath of scoliosis surgery.

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.

The purpose of this study is to determine and characterize the scientific and nonscientific factors that influence the rate of article citation in the field of plastic surgery. Cross-sectional study. We reviewed all entries in Annals of Plastic Surgery and Journal of Plastic, Reconstructive, and Aesthetic Surgery from January 1, 2007 to December 31, 2007; and Plastic and Reconstructive Surgery from January 1, 2007 to December 31, 2008. All scientific articles were analyzed and several article characteristics were extracted. The number of citations at 5 years was collected as the outcome variable. A multivariable analysis was performed to determine which variables were associated with higher citations rates. A total of 2456 articles were identified of which only 908 fulfilled the inclusion criteria. Most studies were publications in the fields of reconstructive (26.3%) or pediatric/craniofacial (17.6%) surgery. The median number of citations 5 years from publication was 8. In the multivariable analysis, factors associated with higher citations rates were subspecialty field (p = 0.0003), disclosed conflict of interest (p = 0.04), number of authors (p = 0.04), and journal (p = 0.02). We have found that higher level of evidence (or other study methodology factors) is not associated with higher citation rates. Instead, conflict of interest, subspecialty topic, journal, and number of authors are strong predictors of high citation rates in plastic surgery.

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.

Recently, nerve-sparing (NS) techniques have been incorporated in surgeries for deep infiltrating endometriosis (DIE) to prevent urinary complications. Our aim was to perform a systematic review and meta-analysis to assess the risk of urinary retention after NS surgery for DIE compared with classical (non-NS) techniques. Following the MOOSE guidelines for systematic reviews of observational studies, data were collected from published research articles that compared NS techniques with non-NS techniques in DIE surgery, with regard to post-operative urinary complications. randomized clinical trials, intervention or observational (cohort and case-control) studies assessing women who underwent surgery for painful DIE. cancer surgery and women submitted to bladder or ureteral resections. The respective relative risks (RR) and 95% confidence intervals (CI) were extracted and a forest plot was generated to show individual and combined estimates. Preliminarily, 1,270 potentially relevant studies were identified from which four studies were selected. A meta-analysis was performed to assess the risk of urinary retention at discharge and 90 days after surgery. We found a common RR of 0.19 [95%CI: 0.03-1.17; (I 2  = 50.20%; P = 0.09)] for need of self-catheterization at discharge in the NS group in relation to the conventional technique. Based on two studies, common RR for persistent urinary retention (after 90 days) was 0.16 [95%CI: 0.03-0.84]. Our results suggest significant advantages of the NS technique when considering the RR of persistent urinary retention. Controlled studies evaluating the best approach to manage the urinary tract after complex surgery for DIE are needed. Neurourol.

Previous studies reported conflicting evidence on the effects of obesity on outcomes after gastrointestinal surgery. The aims of this study were to explore the relationship of obesity with major post-operative complications in an international cohort and to present a meta-analysis of all available prospective data. This prospective, multi-centre study included adults undergoing both elective and emergency gastrointestinal resection, reversal of stoma, or formation of stoma. The primary endpoint was 30-day major complications (Clavien-Dindo grades III-V). A systematic search was undertaken for studies assessing the relationship between obesity and major complications after gastrointestinal surgery. Individual patient meta-analysis (IPMA) was used to analyse pooled results. This study included 2519 patients across 127 centres, of whom 560 (22.2%) were obese. Unadjusted major complication rates were lower in obese versus normal weight patients (13.0% versus 16.2%, respectively), but this did not reach statistical significance (p=0.863) on multivariate analysis for patients having surgery for either malignant or benign conditions. IPMA demonstrated that obese patients undergoing surgery for malignancy were at increased risk of major complications (odds ratio 2.10, 95% confidence interval 1.49-2.96, p<0.001), whereas obese patients undergoing surgery for benign indications were at decreased risk (OR 0.59, 95% CI 0.46-0.75, p<0.001), compared to normal weight patients. In our international data, obesity was not found to be associated with major complications following gastrointestinal surgery. Meta-analysis of available prospective data made a novel finding of obesity being associated with different outcomes depending on whether patients were undergoing surgery for benign or malignant disease.

2007-11-01

I conducted a systematic review of the use of propensity score matching in the cardiovascular surgery literature. I examined the adequacy of reporting and whether appropriate statistical methods were used. I examined 60 articles published in the Annals of Thoracic Surgery, European Journal of Cardio-thoracic Surgery, Journal of Cardiovascular Surgery, and the Journal of Thoracic and Cardiovascular Surgery between January 1, 2004, and December 31, 2006. Thirty-one of the 60 studies did not provide adequate information on how the propensity score-matched pairs were formed. Eleven (18%) of studies did not report on whether matching on the propensity score balanced baseline characteristics between treated and untreated subjects in the matched sample. No studies used appropriate methods to compare baseline characteristics between treated and untreated subjects in the propensity score-matched sample. Eight (13%) of the 60 studies explicitly used statistical methods appropriate for the analysis of matched data when estimating the effect of treatment on the outcomes. Two studies used appropriate methods for some outcomes, but not for all outcomes. Thirty-nine (65%) studies explicitly used statistical methods that were inappropriate for matched-pairs data when estimating the effect of treatment on outcomes. Eleven studies did not report the statistical tests that were used to assess the statistical significance of the treatment effect. Analysis of propensity score-matched samples tended to be poor in the cardiovascular surgery literature. Most statistical analyses ignored the matched nature of the sample. I provide suggestions for improving the reporting and analysis of studies that use propensity score matching.

Interest in cosmetic surgery and body image: views of men and women across the lifespan.

Little is known about interest in cosmetic surgery among the general public or how this interest is related to gender, age, relationship status, body mass index, or body image satisfaction. The present study tested these associations among a sample of 52,677 heterosexual men and women aged 18 to 65 years who completed the online "ELLE/MSBNC.com Sex and Body Image Survey" in 2003. Many women were interested (48 percent) or possibly interested (23 percent) in cosmetic surgery. A substantial minority of men were also interested (23 percent) or possibly interested (17 percent) in cosmetic surgery. Individuals interested in cosmetic surgery did not report poorer global body image than individuals not interested in cosmetic surgery. Individuals specifically interested in liposuction, however, tended to have poorer body image, and interest in liposuction was greater among heavier individuals. The finding that many women and men are interested in cosmetic surgery has implications for research comparing cosmetic surgery patients to individuals drawn from the general population. Specifically, researchers conducting comparative studies should recognize that many individuals in their control group may be strongly interested in cosmetic surgery, even if they have not yet had any. Furthermore, individuals interested in different types of cosmetic surgery may differ from each other on such attributes as body mass index and body image.

Laparoscopic surgery for colorectal disease has become widespread as a minimally invasive treatment. This is important because the increasing availability of new devices allows us to perform procedures with a reduced length of surgery and decreased blood loss. We herein report the results of a literature review of energy sources for laparoscopic colorectal surgery, focused especially on 6 studies comparing ultrasonic coagulating shears (UCS) and other instruments. We also describe our laparoscopic dissection techniques using UCS for colorectal cancer. The short-term outcomes of surgeries using UCS and Ligasure for laparoscopic colorectal surgery were superior to conventional electrosurgery. Some authors have reported that the length of surgery or blood loss when Ligasure was used for laparoscopic colorectal surgery is less than when UCS was used. On the other hand, a recent study demonstrated that there were no significant differences between the short-term outcomes of UCS and Ligasure for laparoscopic colorectal surgery. It is therefore suggested that the choice of technique used should be made according to the surgeon’s preference. We also describe our laparoscopic dissection techniques using UCS (Harmonic ACE) for colorectal cancer with regard to the retroperitoneum dissection, dissection technique, dissection technique around the feeding artery, and various other dissection techniques. We therefore review the outcomes of using various energy sources for laparoscopic colorectal surgery and describe our laparoscopic dissection techniques with UCS (Harmonic ACE) for colorectal cancer.

To investigate the possible influence of risk factors on seizure outcome after surgery for drug-resistant temporal lobe epilepsy (TLE) and mesial temporal sclerosis (MTS). This retrospective study recruited patients with drug-resistant MTS-TLE who underwent epilepsy surgery at Jefferson Comprehensive Epilepsy Center and were followed for a minimum of 1 year. Patients had been prospectively registered in a database from 1986 through 2014. After surgery outcome was classified into 2 groups: seizure-free or relapsed. The possible risk factors influencing long-term outcome after surgery were investigated. A total of 275 patients with MTS-TLE were studied. Two thirds of the patients had Engel's class 1 outcome and 48.4% of the patients had sustained seizure freedom, with no seizures since surgery. Patients with a history of tonic-clonic seizures in the year preceding surgery were more likely to experience seizure recurrence (odds ratio, 2.4; 95% confidence interval 1.19-4.80; P = 0.01). Gender, race, family history of epilepsy, history of febrile seizure, history of status epilepticus, duration of disease before surgery, intelligence quotient, and seizure frequency were not predictors of outcome. Many patients with drug-resistant MTS-TLE respond favorably to surgery. It is critical to distinguish among different types and etiologies of TLE when predicting outcome after surgery.

Thyroid surgery is a clean procedure and therefore antibiotic prophylaxis is not routinely recommended by most international guidelines. However, antibiotics are often used in clinical practice. We enrolled 2926 patients who performed a thyroid surgical operation between the years 2009 and 2011 in the 38 centers of endocrine surgery that joined the UEC--Italian Endocrine Surgery Units Association. Antibiotic prophylaxis was used in 1132 interventions (38.7%). In case of antibiotic prophylaxis, cephalosporins or aminopenicillins ± beta lactamase inhibitors were employed. At logistic regression analysis the use of drainage or device and the presence of malignancy were independent predictors of antibiotic prophylaxis employment. In conclusion our study shows that antibiotic prophylaxis was not rarely used in clinical practice in the setting of thyroid surgery. Drainage apposition, use of device, and malignant disease were independent predictors for antibiotic prophylaxis employment. More data on everyday practice and infection rate in well-designed studies are warranted to provide definitive recommendations on the utility of antibiotic prophylaxis in this setting. According to our experience, we don't consider to be strictly necessary the antibiotic prophylaxis employment in order to reduce infection rate in thyroid surgery.

To potentially improve outcomes in pancreatic resection, robot-assisted pancreatic surgery has been introduced. This technique has possible advantages over laparoscopic surgery, such as its affordance of three-dimensional vision and increased freedom of movement of instruments. A systematic review was performed to assess the safety and feasibility of robot-assisted pancreatic surgery. The literature published up to 30 September 2011 was systematically reviewed, with no restrictions on publication date. Studies reporting on over five patients were included. Animal studies, studies not reporting morbidity and mortality, review articles and conference abstracts were excluded. Data were extracted and weighted means were calculated. A total of 499 studies were screened, after which eight cohort studies reporting on a total of 251 patients undergoing robot-assisted pancreatic surgery were retained for analysis. Weighted mean operation time was 404 ± 102 min (510 ± 107 min for pancreatoduodenectomy only). The rate of conversion was 11.0% (16.4% for pancreatoduodenectomy only). Overall morbidity was 30.7% (n = 77), most frequently involving pancreatic fistulae (n = 46). Mortality was 1.6%. Negative surgical margins were obtained in 92.9% of patients. The rate of spleen preservation in distal pancreatectomy was 87.1%. Robot-assisted pancreatic surgery seems to be safe and feasible in selected patients and, in left-sided resections, may increase the rate of spleen preservation. Randomized studies should compare the respective outcomes of robot-assisted, laparoscopic and open pancreatic surgery. © 2012 International Hepato-Pancreato-Biliary Association.

Background To potentially improve outcomes in pancreatic resection, robot-assisted pancreatic surgery has been introduced. This technique has possible advantages over laparoscopic surgery, such as its affordance of three-dimensional vision and increased freedom of movement of instruments. A systematic review was performed to assess the safety and feasibility of robot-assisted pancreatic surgery. Methods The literature published up to 30 September 2011 was systematically reviewed, with no restrictions on publication date. Studies reporting on over five patients were included. Animal studies, studies not reporting morbidity and mortality, review articles and conference abstracts were excluded. Data were extracted and weighted means were calculated. Results A total of 499 studies were screened, after which eight cohort studies reporting on a total of 251 patients undergoing robot-assisted pancreatic surgery were retained for analysis. Weighted mean operation time was 404 ± 102 min (510 ± 107 min for pancreatoduodenectomy only). The rate of conversion was 11.0% (16.4% for pancreatoduodenectomy only). Overall morbidity was 30.7% (n = 77), most frequently involving pancreatic fistulae (n = 46). Mortality was 1.6%. Negative surgical margins were obtained in 92.9% of patients. The rate of spleen preservation in distal pancreatectomy was 87.1%. Conclusions Robot-assisted pancreatic surgery seems to be safe and feasible in selected patients and, in left-sided resections, may increase the rate of spleen preservation. Randomized studies should compare the respective outcomes of robot-assisted, laparoscopic and open pancreatic surgery. PMID:23216773

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.

Research developing targeted treatment focused on coping with children's long-term pain after surgery is needed because of the high prevalence of chronic pain after surgery. This qualitative study aimed to: 1) understand the child's and family's experiences of pain over the course of their surgical experience, and 2) gather stakeholder input regarding potential barriers and facilitators of perioperative intervention delivery. Fifteen children ages 10 to 18 years who underwent recent major surgery, their primary caregivers, and 17 perioperative health care providers were interviewed. Interviews were coded using semantic thematic analysis. The perioperative period presented emotional challenges for families. Families felt unprepared for surgery and pain. Recovery and regaining physical functioning at home was challenging. Families struggled to return to valued activities. Families reported interest in a perioperative psychosocial intervention. Providers endorsed that families would benefit from enhanced coping skills. They emphasized that families would benefit from more detailed preparatory information. Providers suggested that flexible intervention delivery at home would be ideal. Research developing interventions addressing pain and anxiety in children undergoing major surgery is critically needed. The findings of the present study can inform intervention development with the aim of improving short- as well as long-term recovery in children undergoing major surgery. This qualitative study examined children and their parents' experience of long-term pain and recovery after major surgery, identifying barriers and facilitators of perioperative intervention delivery. Families experienced surgery as stressful, and felt underprepared for pain and recovery. Families and health care providers expressed interest in a preoperative intervention teaching coping skills.

Corrective surgery for congenital heart disease may be life-saving, but its utilisation depends upon several social and economic factors. Girls with cardiac defects may not receive equitable care in India, but this has not been systematically studied. In this prospective study, parents or guardians of 405 consecutive children aged up to 12 years (mean ± SD age 3.43 ± 3.44 years; 271 boys) who had been advised to undergo elective paediatric cardiac surgery were interviewed using a validated questionnaire. The status of the patients was reviewed after a year and the factors associated with non-compliance with treatment were analysed. In a qualitative sub-study the parents of 20 children who had not undergone surgery were interviewed. Qualitative data were analysed using an inductive analytical approach. Of the 405 patients studied, 44% (59/134) of girls had undergone surgery at 1 year compared with 70% (189/271) of boys (χ²=24.97; p<0.001). Independent predictors for non-compliance with surgery included female gender (OR 3.46, 95% CI -2.06 to 5.80; p<0.0001), lower socioeconomic classes (lower-middle: OR 18.62, 95% CI -2.14 to 161.8, p=0.008; upper-lower: OR 34.27, 95% CI -3.72 to 316.0, p=0.002) and higher cost of surgery (OR 1.92, 95% CI -1.06 to 3.47, p=0.03). In the in-depth interviews, apprehensions about future matrimonial prospects of girls and lack of social support emerged as the major factors responsible for delays in undergoing surgery. Female gender is an important determinant of non-compliance with paediatric cardiac surgery. Deep-seated social factors underlie this gender bias.

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 feasibility and safety of robotically assisted procedures in general surgery have been reported from various groups worldwide. Because postoperative complications may lead to longer hospital stays and higher costs overall, analysis of risk factors for postoperative surgical complications in this subset of patients is clinically relevant. The goal of this study was to identify risk factors for postoperative morbidity after robotic surgical procedures in general surgery. We performed an observational monocentric retrospective study. All consecutive robotic surgical procedures from November 2001 to December 2013 were included. One thousand consecutive general surgery patients met the inclusion criteria. The mean overall postoperative morbidity and major postoperative morbidity (Clavien >III) rates were 20.4 and 6 %, respectively. This included a conversion rate of 4.4 %, reoperation rate of 4.5 %, and mortality rate of 0.2 %. Multivariate analysis showed that ASA score >3 [OR 1.7; 95 % CI (1.2-2.4)], hematocrit value <38 [OR 1.6; 95 % CI (1.1-2.2)], previous abdominal surgery [OR 1.5; 95 % CI (1-2)], advanced dissection [OR 5.8; 95 % CI (3.1-10.6)], and multiquadrant surgery [OR 2.5; 95 % CI (1.7-3.8)] remained independent risk factors for overall postoperative morbidity. It also showed that advanced dissection [OR 4.4; 95 % CI (1.9-9.6)] and multiquadrant surgery [OR 4.4; 95 % CI (2.3-8.5)] remained independent risk factors for major postoperative morbidity (Clavien >III). This study identifies independent risk factors for postoperative overall and major morbidity in robotic general surgery. Because these factors independently impacted postoperative complications, we believe they could be taken into account in future studies comparing conventional versus robot-assisted laparoscopic procedures in general surgery.

To evaluate the effect of intracameral carbachol on foveal thickness in patients who underwent uneventful cataract surgery. This retrospective study included two groups: the study group patients (group 1, n = 47 eyes) had uneventful cataract surgery and received only carbachol 0.01 % for miosis; the control group patients (group 2, n = 49 eyes) had uneventful cataract surgery without carbachol or any intracameral medication(s). The groups were compared for foveal thickness after cataract surgery. All phacoemulsification plus intraocular lens implantation surgeries were performed under local anesthesia via temporal clear corneal tunnel incisions. Mean values and standard deviations were calculated for preoperative and postoperative visual acuity (VA) and foveal thickness (FT) at 1 and 4 weeks. Optical coherence tomography was used for the FT measurements, with the MM6 map program. The patients in the study and control groups had a mean age of 57.78 ± 9.07 and 59.72 ± 8.96, respectively (p = 0.355). All eyes had a significant improvement in VA. In the study group, the mean FT at the visits before and 1 and 4 weeks after surgery was 216.87 ± 21.06, 228.81 ± 30.52, and 222.94 ± 29.91 μm, respectively. For the control group, the mean FT, before and 1 and 4 weeks after surgery, was 222.53 ± 17.66, 231.67 ± 23.08, and 225.41 ± 22.59 μm, respectively. Intracameral carbachol 0.01 % had no effect on foveal thickness in patients who underwent uneventful cataract surgery.

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.

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

Obesity has been linked to an increased prevalence in multiple cancers. Studies have suggested a reduction in the overall risk of cancer after bariatric surgery. We reviewed the evidence for bariatric surgery reducing the risk of endometrial cancer. Data was extracted from PubMed, EMBASE, and Medline to perform a systematic review. Thirty-one full text articles were identified from 265 abstracts. Nine observational studies were relevant to endometrial cancer. In the five controlled studies, 462 of 113,032 (0.4%) patients receiving bariatric surgery versus 11,997 of 848,864 (1.4%) controls developed endometrial cancer, odds ratio of 0.317 (95% CI 0.161 to 0.627) using random effects model (P < 0.001). Bariatric surgery seems to reduce the risk of endometrial cancer; however, more research is required.

Laparoscopic Reconstruction in Post-Tubercular Urinary Tract Strictures: Technical Challenges.

Genitourinary tuberculosis still continues to plague developing countries and is a significant cause of morbidity as well as mortality in the developing world. At present, nearly 55% of the patients of genitourinary tuberculosis (GUTB) need surgical management. Owing to the presence of dense adhesions and loss of normal anatomical planes, GUTB was considered to be a contraindication to laparoscopic surgery. However, recent literature shows laparoscopy to be feasible in GUTB. Our study aimed at identifying the challenges in laparoscopic urinary tract reconstructive surgery in genitourinary tuberculosis-related urinary tract obstruction. The details of 6 patients who underwent different types of laparoscopic reconstructive surgery for genitourinary tuberculosis-related urinary tract obstruction from January 2014 to December 2015 were reviewed. Baseline characteristics, indications of surgery, type of surgery, operative duration, blood loss, and follow-up details were noted. All patients received antitubercular treatment before surgery as per the direct observed treatment short-course regimen followed in our country. We performed one bilateral laparoscopic pyeloplasty, one unilateral laparoscopic pyeloplasty, two laparoscopic ureteroneocystostomies, and two ureteroureterostomies. Difficulty was encountered during dissection owing to the presence of adhesions, but conversion to open surgery was not done in five cases. Dense adhesions adjacent to the common iliac vessels necessitated conversion to open surgery in one of the ureteroureterostomies. Stenting was done in all the patients. All patients had uneventful postoperative recovery. Functional imaging following stent removal showed unobstructed tracer flow, showing successful operative outcome. Our study showed that laparoscopic reconstructive surgery is feasible in genitourinary tuberculosis despite the presence of adhesions that may pose a challenge to dissection. This is in contrast to the previous studies which conclude that genitourinary tuberculosis is a relative contraindication to laparoscopic surgery.

Despite the importance of cosmetic surgery in improving body image and promoting individuals' physical and mental health, it is accompanied with some physical, mental, and economic problems, because it is an invasive procedure. Considering such extensive consequences and given the rising demand for performing such surgeries, it is essential to consider programs for reducing such requests. The present study aimed to investigate the psychosocial causes of the tendency for facial cosmetic surgery in patients referred to medical centers in Ahvaz in 2016-2017. This study was conducted on 385 facial cosmetic surgery applicants referred to medical centers in Ahvaz and were selected using a sequential non-probability sampling method. The data collection tool was a questionnaire divided into two sections namely: (1) demographic questions and (2) a questionnaire on the psychosocial causes of the tendency for facial cosmetic surgery. The mean scores of the psychological and social causes of the tendency for facial cosmetic surgery were 4.46 (SD = 1.67) and 3.44 (SD = 2.57), respectively. "Being interested in being beautiful" was the most frequent positive response of the participants regarding the cause of tending to undergo facial cosmetic surgery (88.6%) and the least frequent response was estimated to be 35.1% for the "inappropriate psychological state" cause. The results of this study showed that psychological factors affected the participants' tendency for facial cosmetic surgery more than social factors. Determining and identifying such psychological pressures and providing individual training and psychological support can prevent individuals from undergoing facial cosmetic surgery.

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.

The Top 50 Articles on Minimally Invasive Spine Surgery.

PubMed

Virk, Sohrab S; Yu, Elizabeth

2017-04-01

Bibliometric study of current literature. To catalog the most important minimally invasive spine (MIS) surgery articles using the amount of citations as a marker of relevance. MIS surgery is a relatively new tool used by spinal surgeons. There is a dynamic and evolving field of research related to MIS techniques, clinical outcomes, and basic science research. To date, there is no comprehensive review of the most cited articles related to MIS surgery. A systematic search was performed over three widely used literature databases: Web of Science, Scopus, and Google Scholar. There were four searches performed using the terms "minimally invasive spine surgery," "endoscopic spine surgery," "percutaneous spinal surgery," and "lateral interbody surgery." The amount of citations included was averaged amongst the three databases to rank each article. The query of the three databases was performed in November 2015. Fifty articles were selected based upon the amount of citations each averaged amongst the three databases. The most cited article was titled "Extreme Lateral Interbody Fusion (XLIF): a novel surgical technique for anterior lumbar interbody fusion" by Ozgur et al and was credited with 447, 239, and 279 citations in Google Scholar, Web of Science, and Scopus, respectively. Citations ranged from 27 to 239 for Web of Science, 60 to 279 for Scopus, and 104 to 462 for Google Scholar. There was a large variety of articles written spanning over 14 different topics with the majority dealing with clinical outcomes related to MIS surgery. The majority of the most cited articles were level III and level IV studies. This is likely due to the relatively recent nature of technological advances in the field. Furthermore level I and level II studies are required in MIS surgery in the years ahead. 5.

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.

Inconsistent findings have been reported regarding the efficacy and safety of endoscopic and microscopic transsphenoidal surgery for pituitary adenoma. This study aimed to assess the benefits and shortcomings of these surgical methods in patients with pituitary adenoma. The electronic databases PubMed, Embase, and the Cochrane Library were systematically searched, as well as proceedings of major meetings. Eligible studies with a retrospective or prospective design that evaluated endoscopic versus microscopic methods in patients with pituitary adenoma were included. Primary outcomes included gross tumor removal, cerebrospinal fluid leak, diabetes insipidus, and other complications. Overall, 23 studies (4 prospective and 19 retrospective) assessing 2272 patients with pituitary adenoma were included in the final analysis. Endoscopic transsphenoidal surgery was associated with a higher incidence of gross tumor removal (odds ratio, 1.52; 95% confidence interval, 1.11-2.08; P = 0.009) than those with microscopic transsphenoidal surgery. In addition, endoscopic transsphenoidal surgery had no significant effect on the risk of cerebrospinal fluid leak, compared with microscopic transsphenoidal surgery. Furthermore, endoscopic transsphenoidal surgery was associated with a 22% reduction in risk of diabetes insipidus compared with microscopic transsphenoidal surgery, but the difference was not statistically significant. Endoscopic transsphenoidal surgery significantly reduced the risk of septal perforation (odds ratio, 0.29; 95% confidence interval, 0.11-0.78; P = 0.014) and was not associated with the risk of meningitis, epistaxis, hematoma, hypopituitarism, hypothyroidism, hypocortisolism, total mortality, and recurrence. Endoscopic transsphenoidal surgery is associated with higher gross tumor removal and lower incidence of septal perforation in patients with pituitary adenoma. Future large-scale prospective randomized controlled trials are needed to verify these findings. Copyright © 2017 Elsevier Inc. All rights reserved.

Abstract Background: Metabolic syndrome is associated with higher risk for cardiovascular disease, sleep apnea, and nonalcoholic steatohepatitis, all common conditions in patients referred for bariatric surgery, and it may predict early postoperative complications. The objective of this study was to determine the prevalence of metabolic syndrome, defined using updated National Cholesterol Education Program criteria, in adults undergoing bariatric surgery and compare the prevalence of baseline co-morbid conditions and select operative and 30-day postoperative outcomes by metabolic syndrome status. Methods: Complete metabolic syndrome data were available for 2275 of 2458 participants enrolled in the Longitudinal Assessment of Bariatric Surgery-2 (LABS-2), an observational cohort study designed to evaluate long-term safety and efficacy of bariatric surgery in obese adults. Results: The prevalence of metabolic syndrome was 79.9%. Compared to those without metabolic syndrome, those with metabolic syndrome were significantly more likely to be men, to have a higher prevalence of diabetes and prior cardiac events, to have enlarged livers and higher median levels of liver enzymes, a history of sleep apnea, and a longer length of stay after surgery following laparoscopic Roux-en-Y gastric bypass (RYGB) and gastric sleeves but not open RYGB or laparoscopic adjustable gastric banding. Metabolic syndrome status was not significantly related to duration of surgery or rates of composite end points of intraoperative events and 30-day major adverse surgical outcomes. Conclusions: Nearly four in five participants undergoing bariatric surgery presented with metabolic syndrome. Establishing a diagnosis of metabolic syndrome in bariatric surgery patients may identify a high-risk patient profile, but does not in itself confer a higher risk for short-term adverse postsurgery outcomes.

Complete metabolic syndrome data were available for 2275 of 2458 participants enrolled in the Longitudinal Assessment of Bariatric Surgery-2 (LABS-2), an observational cohort study designed to evaluate long-term safety and efficacy of bariatric surgery in obese adults. The prevalence of metabolic syndrome was 79.9%. Compared to those without metabolic syndrome, those with metabolic syndrome were significantly more likely to be men, to have a higher prevalence of diabetes and prior cardiac events, to have enlarged livers and higher median levels of liver enzymes, a history of sleep apnea, and a longer length of stay after surgery following laparoscopic Roux-en-Y gastric bypass (RYGB) and gastric sleeves but not open RYGB or laparoscopic adjustable gastric banding. Metabolic syndrome status was not significantly related to duration of surgery or rates of composite end points of intraoperative events and 30-day major adverse surgical outcomes. Nearly four in five participants undergoing bariatric surgery presented with metabolic syndrome. Establishing a diagnosis of metabolic syndrome in bariatric surgery patients may identify a high-risk patient profile, but does not in itself confer a higher risk for short-term adverse postsurgery outcomes.

The aim of this study is to highlight the value of the success rate performance of a surgery while planning patient flow within a supply chain of a health care organization/hospital. The paper has considered one of the common surgeries, cataract, and the complications that subsequently result from this surgery. The study employs interpretive structural modeling (ISM) approach to draw a roadmap to study various complications causing cataract that subsequently help in planning and coordination of patient flow. The study finds that there is a hierarchy of causes and certain complications, the persistence of which gives a higher success rate performance in cataract surgery as compared to others. The paper provides leverage to the decision maker while organizing the patient flow depending upon the information of hierarchy of complication of a disease, and accordingly ensures the availability of resources to the patient. The study is of value in identifying the degree of complications from cataract surgery. Given the degree of complication, the patient logistics can be planned myopically in a health care organization which largely depends upon the degree of success rate. The paper attempts to suggest that the hierarchy obtained through ISM can be implemented in the modules of an enterprise resource planning (ERP) set up.

Bariatric surgery is associated with sustained weight loss and improved physical health status for severely obese individuals. Mental health conditions may be common among patients seeking bariatric surgery; however, the prevalence of these conditions and whether they are associated with postoperative outcomes remains unknown. To determine the prevalence of mental health conditions among bariatric surgery candidates and recipients, to evaluate the association between preoperative mental health conditions and health outcomes following bariatric surgery, and to evaluate the association between surgery and the clinical course of mental health conditions. We searched PubMed, MEDLINE on OVID, and PsycINFO for studies published between January 1988 and November 2015. Study quality was assessed using an adapted tool for risk of bias; quality of evidence was rated based on GRADE (Grading of Recommendations Assessment, Development and Evaluation) criteria. We identified 68 publications meeting inclusion criteria: 59 reporting the prevalence of preoperative mental health conditions (65,363 patients) and 27 reporting associations between preoperative mental health conditions and postoperative outcomes (50,182 patients). Among patients seeking and undergoing bariatric surgery, the most common mental health conditions, based on random-effects estimates of prevalence, were depression (19% [95% CI, 14%-25%]) and binge eating disorder (17% [95% CI, 13%-21%]). There was conflicting evidence regarding the association between preoperative mental health conditions and postoperative weight loss. Neither depression nor binge eating disorder was consistently associated with differences in weight outcomes. Bariatric surgery was, however, consistently associated with postoperative decreases in the prevalence of depression (7 studies; 8%-74% decrease) and the severity of depressive symptoms (6 studies; 40%-70% decrease). Mental health conditions are common among bariatric surgery patients-in particular, depression and binge eating disorder. There is inconsistent evidence regarding the association between preoperative mental health conditions and postoperative weight loss. Moderate-quality evidence supports an association between bariatric surgery and lower rates of depression postoperatively.

The fast-track treatment model can be regarded as the second revolution of colorectal surgery after the introduction of laparoscopic surgery. In the gastro-surgical unit of the Central Hospital of Central Finland, results equivalent to international studies in colorectal surgery have been achieved by using fast-track model. In a study setting, this treatment model has resulted in significant decrease of total treatment costs and speeded up discharge of the patients from the hospital. The fast-track treatment model requires both a motivated, trained medical team and a motivated patient.

The present paper describes experimental and clinical studies of a new method "Apicoaortic-PA" cannulation for mitral valve surgery. Our experimental study showed that this method was more rapid and more physiological for cardiopulmonary bypass. We used this technique in 55 cases of isolated mitral valve surgery with successful results. Our general philosophy of surgical approach to the mitral valve diseases is also discussed. We advocate the utilization of the "Apicoaortic Pulmonary Artery" cannulation method for clinical use in isolated mitral valve surgery through the left thoracotomy.

Minimally invasive techniques have revolutionized operative surgery. Computer aided surgery and robotic surgical systems strive to improve further on currently available minimally invasive surgery and open new horizons. Only several centers are currently using surgical robots and publishing data. In gastrointestinal surgery, robotic surgery is applied to a wide range of procedures, but is still in its infancy. Cholecystectomy, Nissen fundoplication and Heller myotomy are among the most frequently performed operations. The ZEUS (Computer Motion, Goleta, CA) and the da Vinci (Intuitive Surgical, Mountain View, CA) surgical systems are today the most advanced robotic systems used in gastrointestinal surgery. Most studies reported that robotic gastrointestinal surgery is feasible and safe, provides improved dexterity, better visualization, reduced fatigue and high levels of precision when compared to conventional laparoscopic surgery. Its main drawbacks are the absence of force feedback and extremely high costs. At this moment there are no reports to clearly demonstrate the superiority of robotics over conventional laparoscopic surgery. Further research and more prospective randomized trials are needed to better define the optimal application of this new technology in gastrointestinal surgery.

Single-institutional, prospective observational study. To elucidate the perioperative kinetics of presepsin (PSEP) in patients undergoing spinal surgery, and to evaluate the possibility of PSEP in the early diagnosis of surgical site infection (SSI). Early diagnosis of SSI after spinal surgery is important. Although several biomarkers have been used as early indicators of SSI, the specificity of these markers in SSI diagnosis was not high. PSEP was found as a novel diagnostic marker for bacterial sepsis in 2004. However, its kinetics after spinal surgery and its usefulness in early diagnosis of SSI have never been evaluated. A total of 118 patients who underwent elective spinal surgery were enrolled. PSEP was measured before, immediately after, 1 day after, and 1 week after surgery. In patients without postoperative infection, perioperative kinetics of PSEP were analyzed. PSEP levels in patients with postoperative infection were also recorded separately, and their utility in SSI diagnosis was evaluated. In the 115 patients without postoperative infection, the median PSEP value was 126, 171, 194, and 147 pg/mL before, immediately after, 1 day after, and 1 week after surgery, respectively. Compared with the preoperative value, PSEP was significantly higher immediately after surgery and the next day, and return to the preoperative level 1 week after surgery. The estimated reference value for 95 percentile in patients without postoperative infection was 297 pg/mL 1 week after surgery. In three patients with postoperative infection, higher levels (>300 pg/mL) were observed 1 week after surgery. In patients after spinal surgery without infectious complications, blood levels of PSEP may immediately increase and return to preoperative levels 1 week after surgery. The PSEP value of 300 pg/mL 1 week after surgery might be used as a novel indicator for suspected SSI. 4.

The high variability in cardiac surgery length--is one of the main challenges for staff managing productivity. This study aims to evaluate the impact of six interventions on open-heart surgery operating theatre productivity. A discrete operating theatre event simulation model with empirical operation time input data from 2603 patients is used to evaluate the effect that these process interventions have on the surgery output and overtime work. A linear regression model was used to get operation time forecasts for surgery scheduling while it also could be used to explain operation time. A forecasting model based on the linear regression of variables available before the surgery explains 46 per cent operating time variance. The main factors influencing operation length were type of operation, redoing the operation and the head surgeon. Reduction of changeover time between surgeries by inducing anaesthesia outside an operating theatre and by reducing slack time at the end of day after a second surgery have the strongest effects on surgery output and productivity. A more accurate operation time forecast did not have any effect on output, although improved operation time forecast did decrease overtime work. A reduction in the operation time itself is not studied in this article. However, the forecasting model can also be applied to discover which factors are most significant in explaining variation in the length of open-heart surgery. The challenge in scheduling two open-heart surgeries in one day can be partly resolved by increasing the length of the day, decreasing the time between two surgeries or by improving patient scheduling procedures so that two short surgeries can be paired. A linear regression model is created in the paper to increase the accuracy of operation time forecasting and to identify factors that have the most influence on operation time. A simulation model is used to analyse the impact of improved surgical length forecasting and five selected process interventions on productivity in cardiac surgery.

Background: Massive weight loss (MWL) following bariatric surgery frequently results in an excess of overstretched skin causing physical discomfort and negatively affecting quality of life, self-esteem, body image, and physical functioning. Methods: In this cross-sectional study 3 groups were compared: (1) patients prior to bariatric surgery (n = 79), (2) patients after bariatric surgery who had not undergone body contouring surgery (BCS) (n = 252), and (3) patients after bariatric surgery who underwent subsequent BCS (n = 62). All participants completed self-report questionnaires assessing body image (Multidimensional Body-Self Relations Questionnaire, MBSRQ), quality of life (IWQOL-Lite), symptoms of depression (PHQ-9), and anxiety (GAD-7). Results: Overall, 62 patients (19.2%) reported having undergone a total of 90 BCS procedures. The most common were abdominoplasties (88.7%), thigh lifts (24.2%), and breast lifts (16.1%). Post-bariatric surgery patients differed significantly in most variables from pre-bariatric surgery patients. Although there were fewer differences between patients with and without BCS, patients after BCS reported better appearance evaluation (AE), body area satisfaction (BAS), and physical functioning, even after controlling for excess weight loss and time since surgery. No differences were found for symptoms of depression and anxiety, and most other quality of life and body image domains. Discussion: Our results support the results of longitudinal studies demonstrating significant improvements in different aspects of body image, quality of life, and general psychopathology after bariatric surgery. Also, we found better AE and physical functioning in patients after BCS following bariatric surgery compared to patients with MWL after bariatric surgery who did not undergo BCS. Overall, there appears to be an effect of BCS on certain aspects of body image and quality of life but not on psychological aspects on the whole. PMID:25477839

To study postoperative pain relief in major gynaecological surgery by perioperative parecoxib administration in Thammasat University Hospital. This double-blind randomized controlled clinical trial was conducted in Thammasat University Hospital, Pathumthani, Thailand from October 2013 to May 2014. One hundred and twenty patients who underwent elective gynaecological surgery were randomized assigned to study and control groups. Study group (n = 60) received 40 mg parecoxib and control group (n = 60) received placebo at 1 hour before surgery. The postoperative visual analog scale (VAS) at 3, 6, 12 and 24 hours, frequency of meperidine consumption in 24 hours and side effects of parecoxib were recorded. VAS of study group after operation at 3, 6, 12 and 24 hours was significantly lower than control group. Meperidine consumption in placebo group was significantly higher than study group (27.50 ± 19.36 and 48.75 ± 28.15 mg, respectively; p < 0.001). There was no side effect from parecoxib in this study. Intravenous postoperativeparecoxib injection could relief pain and reduced meperidine consumption. Parecoxib could be safely used in gynaecological surgery for postoperative pain relief

Parental risk factors for the development of pediatric acute and chronic postsurgical pain: a longitudinal study.

The goal of this longitudinal study was to examine the associations among psychological factors and pain reports of children and their parents over the 12 month period after pediatric surgery. Included in the study were 83 children aged 8-18 years undergoing major surgery. In each case, the child and one of their parents completed measures of pain intensity and unpleasantness, psychological function, and functional disability at 48-72 hours, 2 weeks (child only), 6 months, and 12 months after surgery. The strength of the correlation coefficients between the psychological measures of the parent and their child increased significantly over time. There was a fair level of agreement between parent ratings of child acute and chronic pain (6 months after surgery) and the child's actual ratings. Parent and child pain anxiety scores 48-72 hours after surgery interacted significantly to predict pain intensity, pain unpleasantness, and functional disability levels 2 weeks after discharge from hospital. Parent pain catastrophizing scores 48-72 hours after surgery predicted child pain intensity reports 12 months later. These results raise the possibility that as time from surgery increases, parents exert greater and greater influence over the pain response of their children, so that by 12 months postsurgery mark, parent pain catastrophizing (measured in the days after surgery) is the main risk factor for the development of postsurgical pain chronicity.

The preoperative reaction and decision-making process regarding colostomy surgery among Chinese rectal cancer patients.

Patients with rectal cancer have issues in adjusting to their permanent colostomy after surgery, and support is required to help them resume normal life. However, few studies have explored the experience and factors that affect a patient's decision-making and maladjustment prior to colostomy surgery. The aim of this study was to explore the experience of rectal cancer patients who have to undergo colostomy surgery. A descriptive, qualitative design was used. We studied a purposive sample of 18 patients who had received a diagnosis of primary rectal cancer and were expecting permanent colostomy surgery. The thematic analysis approach was used to analyze the data collected using semi-structured, open-ended questions. The overriding theme that emerged was 'stoma dilemma: a hard decision-making process'. From this main theme, three themes were derived: the resistance stage, the hesitation stage, and the acquiescence stage. It is hard for preoperative rectal patients to choose to undergo stoma surgery or a sphincter-saving operation. From the initial stage of definitive diagnosis to the final consent to stoma surgery, most patients experience the resistance and hesitation stages before reaching the acquiescence stage. Arriving at a decision is a process that nurses can facilitate by eliminating unnecessary misunderstanding surrounding colostomy surgery and by fully respecting patients' right to choose at the various stages.

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.

An increasing emphasis has been placed across health care on evidence-based medicine with higher level studies, such as randomized trials and prospective cohort studies. Historically, clinical research in orthopaedic surgery has been dominated by studies with low patient numbers from a limited number of surgeons. The purpose of this study was to test our hypothesis that orthopaedics has fewer multi-center collaborative studies as compared to other medical disciplines. We chose three leading journals from general medicine, a leading journal from the surgical subspecialties of obstetrics and gynecology, ophthalmology and otolaryngology, and three leading journals from orthopaedic surgery based on highest impact factor. We compared the percentage of collaborative studies and the number of contributing institutions and authors in original research manuscripts published in 2009 between general medical, surgical subspecialty and orthopaedic surgery journals. A significantly higher percentage of manuscripts resulted from multicenter collaborative efforts in the general medical literature (p < 0.000001) and the other surgical subspecialty literature (p < 0.000001) compared to the orthopaedic surgery literature. Manuscripts published in the general medical journals came from more institutions (p < 0.0001) and had significantly more authors (p < 0.000001) than those published in the orthopaedic surgery journals. There is an opportunity to stimulate greater multicenter collaborative research, which correlates with increased patient numbers, a higher level of evidence and more generalizable findings, in the orthopaedic surgery community. These efforts can be supported through increased funding, surgeon participation, and appropriate expansion of authorship for multicenter studies in orthopaedic journals.

Hyperoxaluria and Bariatric Surgery

NASA Astrophysics Data System (ADS)

Asplin, John R.

2007-04-01

Bariatric surgery as a means to treat obesity is becoming increasingly common in the United States. An early form of bariatric surgery, the jejunoileal bypass, had to be abandoned in 1980 due to numerous complications, including hyperoxaluria and kidney stones. Current bariatric procedures have not been systematically evaluated to determine if they cause hyperoxaluria. Presented here are data showing that hyperoxaluria is the major metabolic abnormality in patients with bariatric surgery who form kidney stones. Further studies are needed to assess the prevalence of hyperoxaluria in all patients with bariatric surgery.

The objective of this study is to describe plastic surgery publications in terms of methodology, level of evidence, approval by institutional review board, method of consent, and subspecialty. The 8 top-ranked plastic surgery journals were selected. We manually reviewed the last 40 original articles in each plastic surgery journal, to represent more than 2 months of publications for all journals (range: 3-17 months). Only clinical original articles on human subjects were included. Each article was read at least twice by two different reviewers to ensure accurate data transcription, and then graded by written criteria. One of the senior authors was asked to make a final decision in case of doubt. Among the articles reviewed, 320 were analyzed. The geographical origin of these publications were Asia (32.5%), Europe (30%), US (28.4%), South America (5.6%), Africa (2.5%), and finally Oceania (1%). Reconstructive surgery remains the specialty area most represented in the journals with almost half of the publications, followed by breast surgery (24%) and plastic surgery (19%). A total of 75.6% were retrospective studies. Nearly 80% of the studies were of low level of evidence. Only 3.5% were randomized trials. Less than 40% of the publications mentioned approval by an institutional committee, and 22.6% a patient's informed consent. This study aimed to analyze the quality of plastic surgery publications, taking into account the criteria of Evidence Based Medicine. This work showed that more than half of the studies did not mention an institutional review board approval (Ethics Committee), and that three quarter of the studies did not indicate the presence of patient's informed consent. Ultimately, over 80% of the studies were of low level of evidence. The top-ranked journals have already imposed guidelines corresponding to the methodology requirements to publish clinical studies in their pages, such as EQUATOR criteria for the PRS journal. Efforts are therefore to be done to raise the scientific level of the publications of our specialty. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

There has been rapid growth in the purchase of surgical robots in both North America and Europe in recent years. Whilst this technology promises many benefits for patients, the introduction of such a complex interactive system into healthcare practice often results in unintended consequences that are difficult to predict. Decision making by surgeons during an operation is affected by variables including tactile perception, visual perception, motor skill, and instrument complexity, all of which are changed by robotic surgery, yet the impact of robotic surgery on decision making has not been previously studied. Drawing on the approach of realist evaluation, we conducted a multi-site interview study across nine hospitals, interviewing 44 operating room personnel with experience of robotic surgery to gather their perspectives on how robotic surgery impacts surgeon decision making. The findings reveal both potential benefits and challenges of robotic surgery for decision making. PMID:26958244

Individuals perform mate retention behaviors to minimize the risk of partner infidelity and relationship dissolution. The current study investigates whether consideration of cosmetic surgery can be conceptualized as part of a broader strategy of mate retention for women, but not men. We hypothesized that women's consideration of cosmetic surgery would be positively associated with performance frequencies of Benefit-Provisioning and Cost-Inflicting mate retention behaviors. We recruited 203 individuals (54% women) in committed heterosexual relationships from Tehran, Iran. Results indicate a positive association between consideration of cosmetic surgery and Benefit-Provisioning mate retention behaviors for women, but not men. There was no association between consideration of cosmetic surgery and Cost-Inflicting mate retention behaviors. Women therefore may consider cosmetic surgery to improve their physical attractiveness as part of a Benefit-Provisioning strategy to retain a long-term mate. We discuss limitations of the study and highlight future directions for research from an evolutionary perspective.

To study the relationship between cerebral hemodynamics and clinical performance in normal pressure hydrocephalus (NPH), before and after surgery. Ten patients were studied prospectively before and 3 months after shunt surgery by means of transcranial Doppler (TCD). Clinical performance was scored by means of an NPH scale and the modified Rankin scale. Peak systolic and mean cerebral blood flow velocity (MCV) were lower and cerebrovascular CO2 reactivity was higher after shunt surgery. The three patients with clinical improvement had higher preoperative end diastolic cerebral blood flow velocity and MCV. All postoperative cerebral blood flow velocities were higher in patients with clinical improvement. Our data suggest that higher cerebral blood flow velocity before surgery in patients with NPH is related to clinical improvement after shunt surgery. Cerebral hemodynamic parameters may develop into predictors of successful shunt surgery in patients with normal pressure hydrocephalus.

To examine how corneal astigmatism changes with age over 20 years after cataract surgery and to assess whether the changes differ from those in eyes that did not have surgery. Hayashi Eye Hospital, Fukuoka, Japan. Retrospective case study. Using an autokeratometer, corneal astigmatism was measured preoperatively, at baseline (the day the surgically induced astigmatism stabilized), and 10 years and 20 years after baseline. The change in corneal astigmatism between baseline and 10 years, 10 years and 20 years, and baseline and 20 years was determined using power vector analysis and compared between the time intervals and between groups. The study assessed 74 eyes that had phacoemulsification with a horizontal scleral incision more than 21 years ago (surgery group) and 68 eyes that did not have surgery (no-surgery group). The mean vertical/horizontal change in corneal astigmatism (J0) between baseline and 20 years was -0.64 diopter (D) in the surgery group and -0.49 D in the no-surgery group. The oblique change (J45) was -0.03 D in the surgery group and 0.07 D in the no-surgery group. Using multivariate comparison, the mean J0 and J45 values were not significantly different between baseline and 10 years or between 10 years and 20 years in both groups (P ≥ .2350). The J0 and J45 values were not significantly different between the 2 groups at any time interval (P ≥ .1331). Corneal astigmatism continues to change toward against-the-rule astigmatism over 20 years after cataract surgery. This change was similar in eyes that did not have surgery.

Background: In 2009, the Ontario Bariatric Network was established to address the exploding demand by Ontario residents for bariatric surgery services outside Canada. We compared the use of postoperative hospital services between out-of-country surgery recipients and patients within the Ontario Bariatric Network. Methods: We conducted a population-based, comparative study using administrative data held at the Institute for Clinical Evaluative Sciences. We included Ontario residents who underwent bariatric surgery between 2007 and 2012 either outside the country or at one of the Ontario Bariatric Network's designated centres of excellence. The primary outcome was use of hospital services in Ontario within 1 year after surgery. Results: A total of 4852 patients received bariatric surgery out of country, and 5179 patients underwent surgery through the Ontario Bariatric Network. After adjustment, surgery at a network centre was associated with a significantly lower utilization rate of postoperative hospital services than surgery out of country (rate ratio 0.90, 95% confidence interval [CI] 0.84 to 0.97). No statistically significant differences were found with respect to time in critical care or mortality. However, the physician assessment and reoperation rates were significantly higher among patients who received surgery at a network centre than among those who had bariatric surgery out of country (rate ratio 4.10, 95% CI 3.69 to 4.56, and rate ratio 1.84, 95% CI 1.34 to 2.53, respectively). Interpretation: The implementation of a comprehensive, multidisciplinary provincial program to replace outsourcing of bariatric surgical services was associated with less use of postoperative hospital services by Ontario residents undergoing bariatric surgery. Future research should include an economic evaluation to determine the costs and benefits of the Ontario Bariatric Network. PMID:27730113

The introduction of the laparoscope led to the progress of surgery to a new era, where surgeries that were deemed major are now being performed through keyhole incisions with comparable outcomes to open surgery. However, with this new technique rose several problems like inaccurate depth perception, diminished tactile feedback, need for experienced assistance, and reduction in degrees of motion of the surgeons hands all of which inspired surgeons and engineers to look for mechanical tools to help in reducing these problems. Henceforth; came the application of robotics in surgery. A PubMed and Medline search was performed on cardiac robotic surgery and its applications in mitral valve repair and coronary artery surgery. A total of twenty one articles were picked that allude to the subject. A history of robotic surgery was outlined followed by applications of robotic manipulation in cardiac surgery was narrated. A quick overview of this technology in telemedicine was then outlined followed by future prospects of this technology in surgery was contemplated. The experience of the group from St. Mary's Hospital, London in this field was outlined. During the period of 4 years a total of 102 cases of robotic cardiac surgery were performed. The mean length of hospital stay was 3.1 days with a standard deviation of 1.4 days and the morbidity of the series explained. There was no mortality. Early studies have shown that minimally invasive cardiac surgery is feasible and yields results similar to conventional cardiac surgery, yet it is more technically demanding on the surgeon. As advantageous as this new modality is, further multicenter studies are needed to prove its efficacy. Copyright 2006 John Wiley & Sons, Ltd.

The objective of the study was to assess common practice in pediatric epilepsy surgery in Italy between 2008 and 2014. A survey was conducted among nine Italian epilepsy surgery centers to collect information on presurgical and postsurgical evaluation protocols, volumes and types of surgical interventions, and etiologies and seizure outcomes in pediatric epilepsy surgery between 2008 and 2014. Retrospective data on 527 surgical procedures were collected. The most frequent surgical approaches were temporal lobe resections and disconnections (133, 25.2%) and extratemporal lesionectomies (128, 24.3%); the most frequent etiologies were FCD II (107, 20.3%) and glioneuronal tumors (105, 19.9%). Volumes of surgeries increased over time independently from the age at surgery and the epilepsy surgery center. Engel class I was achieved in 73.6% of patients (range: 54.8 to 91.7%), with no significant changes between 2008 and 2014. Univariate analyses showed a decrease in the proportion of temporal resections and tumors and an increase in the proportion of FCDII, while multivariate analyses revealed an increase in the proportion of extratemporal surgeries over time. A higher proportion of temporal surgeries and tumors and a lower proportion of extratemporal and multilobar surgeries and of FCD were observed in low (<50surgeries/year) versus high-volume centers. There was a high variability across centers concerning pre- and postsurgical evaluation protocols, depending on local expertise and facilities. This survey reveals an increase in volume and complexity of pediatric epilepsy surgery in Italy between 2008 and 2014, associated with a stable seizure outcome. Copyright © 2017 Elsevier Inc.

The case for restraint in spinal surgery: does quality management have a role to play?

Most quality improvement efforts in surgery have focused on the technical quality of care provided, rather than whether the care was indicated, or could have been provided with a safer procedure. Because risk is inherent in any procedure, reducing the number of unnecessary operations is an important issue in patient safety. In the case of lumbar spine surgery, several lines of evidence suggest that, in at least some locations, there may be excessively high surgery rates. This evidence comes from international comparisons of surgical rates; study of small area variations within countries; increasing surgical rates in the absence of new indications; comparisons of surgical outcomes between geographic areas with high or low surgical rates; expert opinion; the preferences of well-informed patients; and increasing rates of repeat surgery. From a population perspective, reducing unnecessary surgery may have a greater impact on complication rates than improving the technical quality of surgery that is performed. Evidence suggests this may be true for coronary bypass surgery in the US and hysterectomy rates in Canada. Though similar studies have not been done for spine surgery, wide geographic variations in surgical rates suggest that this could be the case for spine surgery as well. We suggest that monitoring geographic variations in surgery rates may become an important aspect of quality improvement, and that rates of repeat surgery may bear special attention. Patient registries can help in this regard, if they are very complete and rigorously maintained. They can provide data on surgical rates; offer post-marketing surveillance for new surgical devices and techniques; and help to identify patient subgroups that may benefit most from certain procedures.

Objectives To test whether cleft centres vary in their use of secondary cleft palate surgery, also known as revision palate surgery, and if so to identify modifiable hospital factors and surgeon factors that are associated with use of secondary surgery. Design Retrospective cohort study. Setting Forty-three paediatric hospitals across the USA. Patients Children with cleft lip and palate who underwent primary cleft palate repair from 1999 to 2013. Main outcome measures Time from primary cleft palate repair to secondary palate surgery. Results We identified 4939 children who underwent primary cleft palate repair. At 10 years after primary palate repair, 44% of children had undergone secondary palate surgery. Significant variation existed among hospitals (p<0.001); the proportion of children undergoing secondary surgery by 10 years ranged from 9% to 77% across hospitals. After adjusting for patient demographics, primary palate repair before 9 months of age was associated with an increased hazard of secondary palate surgery (initial HR 6.74, 95% CI 5.30 to 8.73). Postoperative antibiotics, surgeon procedure volume and hospital procedure volume were not associated with time to secondary surgery (p>0.05). Of the outcome variation attributable to hospitals and surgeons, between-hospital differences accounted for 59% (p<0.001), while between-surgeon differences accounted for 41% (p<0.001). Conclusions Substantial variation in the hazard of secondary palate surgery exists depending on a child’s age at primary palate repair and the hospital and surgeon performing their repair. Performing primary palate repair before 9 months of age substantially increases the hazard of secondary surgery. Further research is needed to identify other factors contributing to variation in palate surgery outcomes among hospitals and surgeons. PMID:29479567

To evaluate the impact of complete removal of endometriosis in case of deep infiltrative endometriosis without digestive involvement, on in vitro fertilization outcomes. Retrospective monocentric study. We included infertile women with deep infiltrative endometriosis without colorectal involvement that underwent IVF. Women were divided in two groups, following their history: "surgery" when they underwent complete endometriosis resection before IVF and "without surgery" when they underwent IVF without endometriosis removal. We analysed IVF outcomes considering pregnancy rates per cycle and cumulative pregnancy rates per patient. We included 72 patients: 35 in the "surgery" group and 37 in the "without surgery" group. Women in the two groups were comparable in terms of baseline characteristics (age, body mass index, anti-Müllerian hormone, antral follicular count), endometriosis localizations and in vitro fertilization parameters. Cumulative pregnancy rates per patient were similar in both groups (40 % in the "surgery" group and 41 % in the "without surgery" group; P=1). Clinical pregnancy rate per cycle were also comparable groups (24 % in the "surgery" group and 28 % in the "without surgery" group; P=0.67). Surgery performed was comparable in women that became pregnant and in women that did not. Age was lower in women that became pregnant (P=0.01) and there were more pregnancy obtained in women under 35 years. In women with deep infiltrative endometriosis without digestive involvement, in vitro fertilization outcomes were not impacted by surgery. Therapeutic choice between IVF or surgery as first-line treatment remains thus questionable and shall be guided by other influencing factors, such as pain symptomatology, age, tubal permeability, ovarian reserve, partner's sperm characteristics and woman's choice.

This study was performed to identify factors associated with the need for revision surgery after in situ decompression of the ulnar nerve for cubital tunnel syndrome. This case-control investigation examined all patients treated at one institution with open in situ decompression for cubital tunnel syndrome between 2006 and 2011. The case patients were 44 failed decompressions that required revision, and the controls were 79 randomly selected patients treated with a single operation. Demographic data and disease-specific data were extracted from the medical records. The rate of revision surgery after in situ decompression was determined from our 5-year experience. A multivariate logistic regression model was used based on univariate testing to determine predictors of revision cubital tunnel surgery. Revision surgery was required in 19% (44 of 231) of all in situ decompressions performed during the study period. Predictors of revision surgery included a history of elbow fracture or dislocation (odds ratio [OR], 7.1) and McGowan stage I disease (OR, 3.2). Concurrent surgery with in situ decompression was protective against revision surgery (OR, 0.19). The rate of revision cubital tunnel surgery after in situ nerve decompression should be weighed against the benefits of a less invasive procedure compared with transposition. When considering in situ ulnar nerve decompression, prior elbow fracture as well as patients requesting surgery for mild clinically graded disease should be viewed as risk factors for revision surgery. Patient factors often considered relevant to surgical outcomes, including age, sex, body mass index, tobacco use, and diabetes status, were not associated with a greater likelihood of revision cubital tunnel surgery.

2014-03-01

Piezosurgery (piezoelectric bone surgery) devices were developed to cut bone atraumatically using ultrasonic vibrations and to provide an alternative to the mechanical and electrical instruments used in conventional oral surgery. Indications for piezosurgery are increasing in oral and maxillofacial surgery, as in other disciplines, such as endodontic surgery. Key features of piezosurgery instruments include their ability to selectively cut bone without damaging adjacent soft tissue, to provide a clear operative field, and to cut without generating heat. Although piezosurgery instruments can be used at most stages of endodontic surgery (osteotomy, root-end resection, and root-end preparation), no published data are available on the effect of piezosurgery on the outcomes of endodontic surgery. To our knowledge, no study has evaluated the effect of piezosurgery on root-end resection, and only 1 has investigated root-end morphology after retrograde cavity preparation using piezosurgery. We conducted a search of the PubMed and Cochrane databases using appropriate terms and keywords related to the use and applications of piezoelectric surgery in endodontic surgery. A hand search also was conducted of issues published in the preceding 2 years of several journals. Two independent reviewers obtained and analyzed the full texts of the selected articles. A total of 121 articles published between January 2000 and December 2013 were identified. This review summarizes the operating principles of piezoelectric devices and outlines the applications of piezosurgery in endodontic surgery using clinical examples. Piezosurgery is a promising technical modality with applications in several aspects of endodontic surgery, but further studies are necessary to determine the influence of piezosurgery on root-end resection and root-end preparation.

To evaluate the results of surgical treatment of gynecomastia in the context of quality of life and satisfaction after the surgery. Fifty male patients (mean age, 25.1 years [SD = 8 years]) who underwent surgery for gynecomastia and completed both (preoperative and postoperative) stages of the study were included in the analysis. The quality-of-life evaluation instrument was The Short Form-36 Health Survey Questionnaire. Additionally, we used a short questionnaire including 2 questions about patient satisfaction with gynecomastia surgery. The overall change in life satisfaction after gynecomastia surgery was 1 point on Likert scale (sign test, P < 0.0001). Participants after gynecomastia surgery scored significantly higher than before the procedure in all Short Form-36 Health Survey Questionnaire domains as well as in 2 main scales Psychical and Physical Health. The changes were especially visible for the domain social functioning and a scale Psychical Health (P < 0.0001). Gynecomastia surgery significantly improved men's life quality in all aspects and especially in the social aspect and psychical health. This indicates that adult men with gynecomastia are a specific group of patients, in which surgery may result in life quality improvement even over the average scores.

This review provides a literature overview of new findings relating nutritional genomics and bariatric surgery. It also describes the importance of nutritional genomics concepts in personalized bariatric management. It includes a discussion of the potential role bariatric surgery plays in altering the three pillars of nutritional genomics: nutrigenetics, nutrigenomics, and epigenetics. We present studies that show the effect of each patient’s genetic and epigenetic variables on the response to surgical weight loss treatment. We include investigations that demonstrate the association of single nucleotide polymorphisms with obesity phenotypes and their influence on weight loss after bariatric surgery. We also present reports on how significant weight loss induced by bariatric surgery impacts telomere length, and we discuss studies on the existence of an epigenetic signature associated with surgery outcomes and specific gene methylation profile, which may help to predict weight loss after a surgical procedure. Finally, we show articles which evidence that bariatric surgery may affect expression of numerous genes involved in different metabolic pathways and consequently induce functional and taxonomic changes in gut microbial communities. The role nutritional genomics plays in responses to weight loss after bariatric surgery is evident. Better understanding of the molecular pathways involved in this process is necessary for successful weight management and maintenance. PMID:28878180

Endocan has been shown to be a marker for several cancers and may show degree of malignancy. The aim of this study is to assess serum levels of endocan before and after surgery on low-grade gliomas (LGGs). Endocan was assayed by commercially available enzyme-linked immunosorbent assay (ELISA) kits in a total of 19 patients and 12 controls. Serial serum samples were obtained before and after surgery (1 st day, 1 st week, and 1 st month of surgery). Control samples were collected from cord blood during cesarean section. The results were compared with control brain tissues. Controls showed significantly lower serum endocan levels compared to before and after surgery ( P < 0.05). There is a trend of increase in mean serum levels from before surgery and during the very early period after surgery (during first week); however, in the first month, mean serum levels became lower. Endocan, a vital molecule for angiogenesis, is highly expressed before and after surgery in LGGs, but long-term data is needed. Furthermore, future studies should include high-grade gliomas to discuss whether endocan is associated with recurrence and response to treatment.

Previous studies have suggested an association between cataract surgery and decreased risk for all-cause mortality potentially through a mechanism of improved health status and functional independence, but the association between cataract surgery and cause-specific mortality has not been previously studied and is not well understood. To examine the association between cataract surgery and total and cause-specific mortality in older women with cataract. This prospective cohort study included nationwide data collected from the Women's Health Initiative (WHI) clinical trial and observational study linked with the Medicare claims database. Participants in the present study were 65 years or older with a diagnosis of cataract in the linked Medicare claims database. The WHI data were collected from January 1, 1993, through December 31, 2015. Data were analyzed for the present study from July 1, 2014, through September 1, 2017. Cataract surgery as determined by Medicare claims codes. The outcomes of interest included all-cause mortality and mortality attributed to vascular, cancer, accidental, neurologic, pulmonary, and infectious causes. Mortality rates were compared by cataract surgery status using the log-rank test and Cox proportional hazards regression models adjusting for demographics, systemic and ocular comorbidities, smoking, alcohol use, body mass index, and physical activity. A total of 74 044 women with cataract in the WHI included 41 735 who underwent cataract surgery. Mean (SD) age was 70.5 (4.6) years; the most common ethnicity was white (64 430 [87.0%]), followed by black (5293 [7.1%]) and Hispanic (1723 [2.3%]). The mortality rate was 2.56 per 100 person-years in both groups. In covariate-adjusted Cox models, cataract surgery was associated with lower all-cause mortality (adjusted hazards ratio [AHR], 0.40; 95% CI, 0.39-0.42) as well as lower mortality specific to vascular (AHR, 0.42; 95% CI, 0.39-0.46), cancer (AHR, 0.31; 95% CI, 0.29-0.34), accidental (AHR, 0.44; 95% CI, 0.33-0.58), neurologic (AHR, 0.43; 95% CI, 0.36-0.53), pulmonary (AHR, 0.63; 95% CI, 0.52-0.78), and infectious (AHR, 0.44; 95% CI, 0.36-0.54) diseases. In older women with cataract in the WHI, cataract surgery is associated with lower risk for total and cause-specific mortality, although whether this association is explained by the intervention of cataract surgery is unclear. Further study of the interplay of cataract surgery, systemic disease, and disease-related mortality would be informative for improved patient care.

Laser-assisted cataract surgery versus standard ultrasound phacoemulsification cataract surgery.

Cataract is the leading cause of blindness in the world, and cataract surgery is one of the most commonly performed operations in the Western world. Preferred surgical techniques have changed dramatically over the past half century with associated improvements in outcomes and safety. Femtosecond laser platforms that can accurately and reproducibly perform key steps in cataract surgery, including corneal incisions, capsulotomy and lens fragmentation, are now available. The potential advantages of laser-assisted surgery are broad, and include greater safety and better visual outcomes through greater precision and reproducibility. To compare the effectiveness of laser-assisted cataract surgery with standard ultrasound phacoemulsification cataract surgery by gathering evidence on safety from randomised controlled trials (RCTs). We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 4), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to May 2016), EMBASE (January 1980 to May 2016), Latin American and Caribbean Health Sciences Literature Database (LILACS) (January 1982 to May 2016), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov), the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en) and the U.S. Food and Drugs Administration (FDA) website (www.fda.gov). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 10 May 2016. We included randomised controlled trials where laser-assisted cataract surgery was compared to standard ultrasound phacoemulsification cataract surgery. We graded the certainty of the evidence using GRADE. Two review authors independently screened the search results, assessed risk of bias and extracted data using the standard methodological procedures expected by Cochrane. The primary outcome for this review was intraoperative complications in the operated eye, namely anterior capsule and posterior capsule tears. The secondary outcomes were visual acuity (corrected distance visual acuity (CDVA) and uncorrected distance visual acuity (UDVA)), refractive outcomes, quality of vision (as measured by any validated visual function score), postoperative complications and cost-effectiveness. We included 16 RCTs conducted in Germary, Hungary, Italy, India, China and Brazil that enrolled a total of 1638 eyes of 1245 adult participants. Overall, the studies were at unclear or high risk of bias. In 11 of the studies the authors reported financial links with the manufacturer of the laser platform evaluated in their studies. Five of the studies were within-person (paired-eye) studies with one eye allocated to one procedure and the other eye allocated to the other procedure. These studies were reported ignoring the paired nature of the data.The number of anterior capsule and posterior capsule tears reported in the included studies for both laser cataract surgery and manual phacoemulsification cataract surgery were low. There were four anterior capsule tears and one posterior capsule tear in 1076 eyes reported in 10 studies (2 anterior capsule tears in laser arms, 2 anterior capsule tears and 1 posterior capsule tear in standard phacoemulsification arms). We are very uncertain as to the effect of laser-assisted surgery compared to standard phacoemulsification surgery with respect to these two outcomes. For postoperative cystoid macular oedema and elevated postoperative intraocular pressures, again the evidence was inconclusive (odds ratio (OR) 0.58, 95% confidence interval (CI) 0.20 to 1.68; 957 eyes, 9 studies, low certainty evidence; and OR 0.57, 95% CI 0.11 to 2.86; 903 eyes, 8 studies, low certainty evidence).We found little evidence of any important difference in postoperative visual acuity between laser-assisted and standard phacoemulsification arms. There was a small advantage for laser-assisted cataract surgery at six months in CDVA. However, the mean difference (MD) was -0.03 logMAR (95% CI -0.05 to -0.00; 224 eyes, 3 studies, low certainty evidence) which is equivalent to 1.5 logMAR letters and is therefore, clinically insignificant. No studies reported patient-reported outcome measures such as visual function.There were no data reported on costs or resource use but three studies reported the time taken to do the surgery. There was little evidence of any major difference between the two procedures in this respect (MD 0.1 minutes, 95% CI -0.02 to 0.21; 274 eyes, low certainty evidence). The evidence from the 16 randomised controlled trials RCTs included in this review could not determine the equivalence or superiority of laser-assisted cataract surgery compared to standard manual phacoemulsification for our chosen outcomes due to the low to very low certainty of the evidence available from these studies. As complications occur rarely, large, adequately powered, well designed, independent RCTs comparing the safety and efficacy of laser-assisted cataract surgery with standard phacoemulsification cataract surgery are needed. Standardised reporting of complications and visual and refractive outcomes for cataract surgery would facilitate future synthesis. Data on patient-reported outcomes and cost-effectiveness are needed. Paired-eye studies should be analysed and reported appropriately.

Pain after surgery continues to be undermanaged. Studies and initiatives aiming to improve the management of postoperative pain are growing; however, most studies focus on inpatients and pain on the first day after surgery. The management of postoperative pain after ambulatory surgery and for several days thereafter is not yet a major focus. One reason is the low return rate of the questionnaires in the ambulatory sector. This article reports the development and feasibility of a web-based electronic data collection system to examine pain and pain-related outcome on predefined postoperative days after ambulatory surgery. In this prospective pilot study 127 patients scheduled for ambulatory surgery were asked to participate in a survey to evaluate aspects related to pain after ambulatory surgery. The data survey was divided in (1) a preoperative, intraoperative and postoperative part and (2) a postoperative internet-based electronic questionnaire which was sent via e-mail link to the patient on days 1, 3 and 7 after surgery. A software was developed using a PHP-based platform to send e-mails and retrieve the data after web-based entries via a local browser. Feasibility, internet-based hitches and compliance were assessed by an additional telephone call after day 7. A total of 100 patients (50 female) between 18 and 71 years (mean 39.1 ± 12.7 years) were included in the pilot study. Return rates of the electronic questionnaires were 86% (days 3 and 7) and 91% (day 1 after surgery). All 3 electronic questionnaires were answered by 82% of patients. Aspects influencing the return rate of questionnaires were work status but not age, gender, education level and preoperative pain. Telephone interviews were performed with 81 patients and revealed high operability of the internet-based survey without any major problems. The user-friendly feasibility and operability of this internet-based electronic data survey system explain the high compliance and return rate of electronic questionnaires by patients at home after ambulatory surgery. This survey tool therefore provides unique opportunities to evaluate and improve postoperative pain management after ambulatory surgery.

Robotics in reproductive surgery: strengths and limitations.

Minimally invasive surgical techniques are becoming increasingly common in gynecologic surgery. However, traditional laparoscopy can be challenging. A robotic surgical system gives several advantages over traditional laparoscopy and has been incorporated into reproductive gynecological surgeries. The objective of this article is to review recent publications on robotically-assisted laparoscopy for reproductive surgery. Recent clinical research supports robotic surgery as resulting in less post-operative pain, shorter hospital stays, faster return to normal activities, and decreased blood loss. Reproductive outcomes appear similar to alternative approaches. Drawbacks of robotic surgery include longer operating room times, the need for specialized training, and increased cost. Larger prospective studies comparing robotic approaches with laparoscopy and conventional open surgery have been initiated and information regarding long-term outcomes after robotic surgery will be important in determining the ultimate utility of these procedures.

ICU needs of nontrauma emergency general surgery patients are poorly described. This study was designed to compare ICU utilization of emergency general surgery patients admitted to an acute care emergency surgery service with other general surgery patients. Our hypothesis is that tertiary care emergency general surgery patients utilize more ICU resources than other general surgical patients. Retrospective database review. Academic, tertiary care, nontrauma surgical ICU. All patients admitted to the surgical ICU over age 18 between March 2004 and June 2012. None. Six thousand ninety-eight patients were evaluated: 1,053 acute care emergency surgery, 1,964 general surgery, 1,491 transplant surgery, 995 facial surgery/otolaryngology, and 595 neurosurgery. Acute care emergency surgery patients had statistically significantly longer ICU lengths of stay than other groups: acute care emergency surgery (13.5 ± 17.4 d) versus general surgery (8.7 ± 12.9), transplant (7.8 ± 11.6), oral-maxillofacial surgery (5.5 ± 4.2), and neurosurgery (4.47 ± 9.8) (all p< 0.01). Ventilator usage, defined by percentage of total ICU days patients required mechanical ventilation, was significantly higher for acute care emergency surgery patients: acute care emergency surgery 73.4% versus general surgery 64.9%, transplant 63.3%, oral-maxillofacial surgery 58.4%, and neurosurgery 53.1% (all p < 0.01). Continuous renal replacement therapy usage, defined as percent of patients requiring this service, was significantly higher in acute care emergency surgery patients: acute care emergency surgery 10.8% versus general surgery 4.3%, transplant 6.6%, oral-maxillofacial surgery 0%, and neurosurgery 0.5% (all p < 0.01). Acute care emergency surgery patients were more likely interhospital transfers for tertiary care services than general surgery or transplant (24.5% vs 15.5% and 8.3% respectively, p < 0.001 for each) and more likely required emergent surgery (13.7% vs 6.7% and 3.5%, all p < 0.001). Chronic comorbidities were similar between acute care emergency surgery and general surgery, whereas transplant had fewer. Emergency general surgery patients have increased ICU needs in terms of length of stay, ventilator usage, and continuous renal replacement therapy usage compared with other services, perhaps due to the higher percentage of transfers and emergent surgery required. These patients represent a distinct population. Understanding their resource needs will allow for better deployment of hospital resources.

Laparoscopic aortobifemoral bypass has become an established treatment option for symptomatic aortoiliac obstructive disease at dedicated centers. Minimally invasive surgical techniques like laparoscopic surgery have often been shown to reduce expenses and increase patients' health-related quality of life. The main objective of our study was to measure quality-adjusted life years (QALYs) and costs after totally laparoscopic and open aortobifemoral bypass. This was a within trial analysis in a larger ongoing randomized controlled prospective multicenter trial, Norwegian Laparoscopic Aortic Surgery Trial. Fifty consecutive patients suffering from symptomatic aortoiliac occlusive disease suitable for aortobifemoral bypass surgery were randomized to either totally laparoscopic (n=25) or open surgical procedure (n=25). One patient dropped out of the study before surgery. We measured health-related quality of life using the EuroQol (EQ-5D-5L) questionnaire at 4 different time points, before surgery and for 6 months during follow-up. We calculated the QALYs gained by using the area under the curve for both groups. Costs were calculated based on prices for surgical equipment, vascular prosthesis and hospital stay. We found a significantly higher increase in QALYs after laparoscopic vs open aortobifemoral bypass surgery, with a difference of 0.07 QALYs, ( p =0.001) in favor of laparoscopic aortobifemoral bypass. The total cost of surgery, equipment and hospital stay after laparoscopic surgery (9,953 €) was less than open surgery (17,260 €), ( p =0.001). Laparoscopic aortobifemoral bypass seems to be cost-effective compared with open surgery, due to an increase in QALYs and lower procedure-related costs.

Purpose: Cataract surgery is the most common intraocular surgery performed all over the world and has advanced technically in recent years. As in all surgeries, complications are unavoidable. Herein we report factors associated with complications and visual outcomes of cataract surgery. Methods: This retrospective cohort study included data of 1,632 cataract surgeries performed from 2007 to 2010 which was obtained from the cataract registry of the Malaysian National Eye Database. Demographic features, ocular and systemic comorbidites, grade of surgeon expertise and duration of surgery, type of anesthesia, intraoperative and postoperative complications, and the type of intraocular lens were recorded. Best corrected visual acuities were compared before and after the operation. Results: Mean patient age was 66.9 years with equal gender distribution. The majority of subjects had age related cataracts. Phacoemulsification was done faster than other surgeries, especially by specialist surgeons. History of prior ocular surgery and operations performed under general anesthesia were associated with greater complications. Phacoemulsification was associated with less complications and better visual outcomes. The age and etiology of cataract did not affect complications. Malays, absence of ocular comorbidities, left eyes and eyes operated under local anesthesia were more likely to experience more visual improvement. Gender, age, cause of cataract, systemic comorbidities and surgeon expertise as well as intra-and postoperative complications did not affect the visual outcomes. Conclusion: Phacoemulsification had good visual outcomes in cataract surgery. Duration of surgery, expertise of the surgeon and complications did not affect the visual outcomes. PMID:27051481

A growing number of studies suggest that bariatric surgery is safe and effective for adolescents with severe obesity. However, surprisingly little is known about changes in dietary intake and eating behavior of adolescents who undergo bariatric surgery. Investigate changes in dietary intake and eating behavior of adolescents with obesity who underwent bariatric surgery (n = 119) or lifestyle modification (LM) (n = 169). University-based health systems METHODS: A prospective investigation of 288 participants (219 female and 69 male) prior to bariatric surgery or LM and again 6, 12, and 24 months (surgery patients only) after treatment. Measures included changes in weight, macronutrient intake, eating behavior, and relevant demographic and physiological variables. Adolescents who underwent bariatric surgery experienced significantly greater weight loss than those who received LM. The two groups differed in self-reported intake of a number of macronutrients at 6 and 12 months from baseline, but not total caloric intake. Patients treated with surgery, compared to those treated with LM, also reported significantly greater reductions in a number of disordered eating symptoms. After bariatric surgery, greater weight loss from postoperative month 6 to 12 was associated with self-reported weight consciousness, craving for sweets, and consumption of zinc. Adolescents who underwent bariatric surgery, compared to those who received LM, reported significantly greater reductions in weight after 1 year. They also reported greater reductions in disordered eating symptoms. These findings provide new information on changes in dietary intake and eating behavior among adolescents who undergo bariatric surgery.

Pelvic floor muscle training (PFMT) is often used as a treatment for pelvic organ prolapse (POP) and can improve function. However, the effectiveness of this modality as an adjunct to prolapse surgery for women with POP is unknown. To evaluate whether the use of pelvic floor muscle training as an adjunct to prolapse surgery is superior to surgery alone for women with pelvic organ prolapse. We searched PubMed, Embase, the Cochrane Library, and the Web of Science from their inception dates to June 30, 2014 for data describing randomized controlled trials (RCTs) that compare the efficacy of PFMT with or without lifestyle modification plus surgery versus surgery alone for women with POP. Additional relevant studies were identified by searching the references of retrieved articles and using Google Scholar. Two investigators independently reviewed and selected relevant studies that met the pre-specified inclusion criteria, extracted the data, and assessed the risk of bias in the included studies according to the Cochrane Handbook, version 5.1.0. Due to great heterogeneity in the choice and reporting of outcome measures and the different durations of follow-up among the studies, this analysis is confined to a qualitative systematic review. Five RCTs involving 591 women were reviewed (treatment group [TG], 292 cases; control group [CG], 299 cases). Generally, the five RCTs exhibited low risk of bias. This study indicated no significant improvement in prolapse symptoms, in quality of life, or in the degree of prolapse for women with POP in the TG compared to those in the CG. Insufficient evidence was found to support adding perioperative PFMT to surgery over the use of surgery alone in women undergoing surgery for POP. Adequately, powered RCTs with longer follow-up periods are required to evaluate the long-term effect of perioperative PFMT. Neurourol.

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 use of the vertical rectus abdominis myocutaneous flap in reconstruction after abdominoperineal resection or pelvic exenteration for neoplasia is well documented. However, functional outcomes after vaginal reconstruction, including sexual function, are poorly described. This study aimed to examine sexual function in women following extensive pelvic surgery with colpectomy and vaginal reconstruction with the use of a vertical rectus abdominis myocutaneous flap. This study is a retrospective review of medical records in combination with patient questionnaires. Nonresponders were followed up with a second contact. This study was performed at a tertiary care university medical center (Colorectal Section, Department of Surgery P, Aarhus University Hospital, Denmark) All women undergoing pelvic surgery and simultaneous vaginal reconstruction with the use of a vertical rectus abdominis myocutaneous flap between 2004 and 2010 at our department were identified from a patient database. Thirty women who were alive at the time of identification were included in the study. Sexual function before and after surgery was evaluated by the use of the Sexual function Vaginal changes Questionnaire. The main outcome end point was whether the patient was sexually active after vaginal reconstruction. Twenty-six participants (87%) answered the questionnaire. Fifty percent of patients reported an active sex life before surgery. In general, patients reported an unchanged desire for both physical and sexual contact after surgery. However, only 2 patients (14%) reported being sexually active after surgery. This was a retrospective study with a heterogeneous cohort involving several types of cancers and surgical procedures. Factors other than vertical rectus abdominis myocutaneous flap reconstruction itself may interfere with the sexual function. Extensive pelvic surgery with colpectomy leads to sexual dysfunction even when the vagina is reconstructed with a vertical rectus abdominis myocutaneous flap. This knowledge may improve the quality of information given to this group of patients before surgery.

How Surgeons Conceptualize Talent: A Qualitative Study Using Sport Science as a Lens.

Debates prevail regarding the definition of surgical talent, and how individuals with the potential to become talented surgeons can be identified and developed. However, over the past 30 years, talent has been studied extensively in other domains. The objectives of this study is to explore notions of talent in surgery and sport in order to investigate if the field of surgical education can benefit from expanding its view on talented performances. Therefore, this study aims to use the sport literature as a lens when exploring how surgeons conceptualize and define talent. Semi-structured interviews were conducted with a sample of 11 consultant surgeons from multiple specialties. We used constructivist grounded theory principles to explore talent in surgery. Ongoing data analysis refined the theoretical framework and iteratively informed data collection. Themes were identified iteratively using constant comparison. The setting included 8 separate hospitals across Canada and Denmark. A total of 11 consultant surgeons from 6 different surgical subspecialties (urology, orthopedic surgery, colorectal surgery, general surgery, vascular surgery, head & neck surgery) were included. We identified three key elements for conceptualizing surgical talent: (1) Individual skills makes the surgical prospect "good", (2) a mixture of skills gives the surgical prospect the potential to become talented, and (3) becoming talented may rely on the fit between person and environment. We embarked on a study aimed at understanding talent in surgery. Talent is a difficult construct to agree on. Whether in medicine or sports, debates about talent will continue to persist, as we all perceive talent differently. While we heard different opinions, three key ideas summarize our participants' discussions regarding surgical talent. These findings resonate with the holistic ecological approach from sport science and hence highlight the limits of a reductionist approach while favoring the individual-environment system as the minimal ontology for describing talented performances.

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.

Most studies on patients' experiences following emergency cardiac surgery focus on evaluation of patients after their discharge. Few studies have evaluated patients' experiences after being transferred from intensive care and before being discharged. This study aimed to describe patients' experiences in the early stages of recovery following emergency heart surgery. For this exploratory qualitative descriptive study, 13 patients were recruited from a medical centre in northern Taiwan. Participants had undergone emergency heart surgery and had resided in the cardiothoracic surgical ward for ≥6 days following transfer from the ICU; all expected to be discharged from the hospital within 3 days. Semi-structured, face-to-face interviews were conducted in private after the patients had been transferred to the cardiothoracic surgical wards. Audiotaped interviews were transcribed and analysed using content analysis. Data analysis identified four themes, which represented different recovery stages: sudden and serious symptoms, nightmares and vivid dreams, physical and emotional disturbances, and establishing a new life after emergency surgery. A fifth theme, support for a new lifestyle, occurred between the four stages. Participants experienced symptoms of physical and psychological stress during the early recovery stages following emergency heart surgery. A lack of understanding of the process of recovery increased these difficulties; participants wanted and needed multidisciplinary care and education. Emergency heart surgery does not allow healthcare professionals to inform patients of what to expect post-surgery. Our findings suggest that rather than waiting until discharge to offer disease information and treatment plans, multidisciplinary care should be initiated as soon as possible to facilitate recovery.

Purpose/Aim: Lumbar degenerative diseases (LDDs) cause pain and disability and are treated with lumbar fusion surgery. The aim of this study was to evaluate the efficacy of lumbar fusion surgery with ISOBAR devices versus posterior lumbar interbody fusion (PLIF) surgery for alleviating LDD-associated pain and disability. We performed a literature review and meta-analysis conducted in accordance with Cochrane methodology. The analysis included Group Reading Assessment and Diagnostic Evaluation assessments, Jadad Quality Score evaluations, and Risk of Bias in Non-randomized Studies of Interventions assessments. We searched PubMed, MEDLINE, the Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, ProQuest, the Airiti Library, and the China Academic Journals Full-text Database for relevant randomized controlled trials and cohort studies published in English or Chinese between 1997 and 2017. Outcome measures of interest included general pain, lower back pain, and disability. Of the 18 studies that met the inclusion criteria, 16 examined general pain (802 patients), 5 examined lower back pain (274 patients), and 15 examined disability (734 patients). General pain, lower back pain, and disability scores were significantly lower after lumbar fusion surgery with ISOBAR devices compared to presurgery. Moreover, lumbar fusion surgery with ISOBAR devices was more effective than PLIF for decreasing postoperative disability, although it did not provide any benefit in terms of general pain or lower back pain. Lumbar fusion surgery with ISOBAR devices alleviates general pain, lower back pain, and disability in LDD patients and is superior to PLIF for reducing postoperative disability. Given possible publication bias, we recommend further large-scale studies.

We conducted a multi-center pilot Phase II study to examine the safety of robotic rectal cancer surgery performed using the da Vinci Surgical System during the introduction period of robotic rectal surgery at two institutes based on surgical outcomes. This study was conducted with a prospective, multi-center, single-arm, open-label design to assess the safety and feasibility of robotic surgery for rectal cancer (da Vinci Surgical System). The primary endpoint was the rate of adverse events during and after robotic surgery. The secondary endpoint was the completion rate of robotic surgery. Between April 2014 and July 2016, 50 patients were enrolled in this study. Of these, 10 (20%) had rectosigmoid cancer, 17 (34%) had upper rectal cancer, and 23 (46%) had lower rectal cancer; six underwent high anterior resection, 32 underwent low anterior resection, 11 underwent intersphincteric resection, and one underwent abdominoperineal resection. Pathological stages were Stage 0 in 1 patient, Stage I in 28 patients, Stage II in 7 patients and Stage III in 14 patients. Pathologically complete resection was achieved in all patients. There was no intraoperative organ damage or postoperative mortality. Eight (16%) patients developed complications of all grades, of which 2 (4%) were Grade 3 or higher, including anastomotic leakage (2%) and conversion to open surgery (2%). The present study demonstrates the feasibility and safety of robotic rectal cancer surgery, as reflected by low morbidity and low conversion rates, during the introduction period. © The Author 2017.

The identification of health care institutions with outlying outcomes is of great importance for reporting health care results and for quality improvement. Historically, elective surgical outcomes have received greater attention than nonelective results, although some studies have examined both. Differences in outlier identification between these patient groups have not been adequately explored. The aim of this study was to compare the identification of institutional outliers for mortality after elective and nonelective colorectal resection in England. This was a cohort study using routine administrative data. Ninety-day mortality was determined by using statutory records of death. Adjusted Trust-level mortality rates were calculated by using multiple logistic regression. High and low mortality outliers were identified and compared across funnel plots for elective and nonelective surgery. All English National Health Service Trusts providing colorectal surgery to an unrestricted patient population were studied. Adults admitted for colorectal surgery between April 2006 and March 2012 were included. Segmental colonic or rectal resection was performed. The primary outcome measured was 90-day mortality. Included were 195,118 patients, treated at 147 Trusts. Ninety-day mortality rates after elective and nonelective surgery were 4% and 18%. No unit with high outlying mortality for elective surgery was a high outlier for nonelective mortality and vice versa. Trust level, observed-to-expected mortality for elective and nonelective surgery, was moderately correlated (Spearman ρ = 0.50, p< 0.001). This study relied on administrative data and may be limited by potential flaws in the quality of coding of clinical information. Status as an institutional mortality outlier after elective and nonelective colorectal surgery was not closely related. Therefore, mortality rates should be reported for both patient cohorts separately. This would provide a broad picture of the state of colorectal services and help direct research and quality improvement activities.

Zheng, Xiangpeng; Schipper, Matthew; Department of Biostatistics, the University of Michigan, Ann Arbor, Michigan

Purpose: This study compared treatment outcomes of stereotactic body radiation therapy (SBRT) with those of surgery in stage I non-small cell lung cancer (NSCLC). Methods and Materials: Eligible studies of SBRT and surgery were retrieved through extensive searches of the PubMed, Medline, Embase, and Cochrane library databases from 2000 to 2012. Original English publications of stage I NSCLC with adequate sample sizes and adequate SBRT doses were included. A multivariate random effects model was used to perform a meta-analysis to compare survival between treatments while adjusting for differences in patient characteristics. Results: Forty SBRT studies (4850 patients) and 23 surgerymore » studies (7071 patients) published in the same period were eligible. The median age and follow-up duration were 74 years and 28.0 months for SBRT patients and 66 years and 37 months for surgery patients, respectively. The mean unadjusted overall survival rates at 1, 3, and 5 years with SBRT were 83.4%, 56.6%, and 41.2% compared to 92.5%, 77.9%, and 66.1% with lobectomy and 93.2%, 80.7%, and 71.7% with limited lung resections. In SBRT studies, overall survival improved with increasing proportion of operable patients. After we adjusted for proportion of operable patients and age, SBRT and surgery had similar estimated overall and disease-free survival. Conclusions: Patients treated with SBRT differ substantially from patients treated with surgery in age and operability. After adjustment for these differences, OS and DFS do not differ significantly between SBRT and surgery in patients with operable stage I NSCLC. A randomized prospective trial is warranted to compare the efficacy of SBRT and surgery.« less

Summary Objective To examine the long-term effects of bariatric surgery on female-specific cancer in women with obesity. Methods The prospective, matched Swedish Obese Subjects (SOS) study was designed to examine outcomes after bariatric surgery. This study includes 1420 women from the SOS cohort that underwent bariatric surgery and 1447 contemporaneously matched controls who received conventional obesity treatment. Age was 37–60 years and BMI was ≥38 kg/m2. Information on cancer events was obtained from the Swedish National Cancer Registry. Median follow-up time was 18.1 years (interquartile range 14.8–20.9 years, maximum 26 years). This study is registered with ClinicalTrials.gov, NCT01479452. Results Bariatric surgery was associated with reduced risk of overall cancer (hazard ratio=0.71; 95% CI 0.59–0.85; p<0.001). About half of the observed cancers were female-specific, and the incidence of these were lower in the surgery group compared with the control group (hazard ratio=0.68; 95% CI 0.52–0·88; p=0.004). The surgical treatment benefit with respect to female-specific cancer was significantly associated with baseline serum insulin (interaction p value=0.022), with greater relative treatment benefit in patients with medium or high insulin levels. Separate analyses of different types of female-specific cancers showed that bariatric surgery was associated with reduced risk of endometrial cancer (hazard ratio=0.56: 95% CI 0.35–0.89; p=0.014). Conclusions In this long-term study, bariatric surgery was associated with reduced risk of female-specific cancer, especially in women with hyperinsulinemia at baseline. PMID:28259424

Since its first use for the reconstruction of tissue defects in the oral cavity in 1985, human amniotic membrane (hAM) has been widely studied in the field of oral surgery. Despite the growing number of publications in this field, there is no systematic review or meta-analysis concerning its clinical applications, outcome assessments, and relevance in oral surgery. The aim of this review is to provide a thorough understanding of the potential use of hAM for soft and hard tissue reconstruction in the oral cavity. A systematic electronic and a manual literature search of the MEDLINE-PubMed database and Scopus database was completed. Patient, Intervention, Comparison and Outcomes (PICO) technique was used to select the relevant articles to meet the objective. Studies using hAM for oral reconstruction, and conducted on human subjects, were included in this survey. A total of 17 articles were analyzed. Five areas of interest were identified as potential clinical application: periodontal surgery, cleft palate and tumor reconstruction, prosthodontics and peri-implant surgery. Overall, periodontal surgery was the only discipline to assess the efficacy of hAM with randomized clinical trials. The wide variability of preservation methods of hAM and the lack of objective measurements were observed in this study. hAM is already used in the field of oral surgery. Despite this, there is weak clinical evidence demonstrating convincingly the benefit of hAM in this area compared to standard surgery. Several studies now suggest the interest of hAM for periodontal tissue repair. Due to its biological and mechanical properties, hAM seems to be a promising treatment for wound healing in various areas of oral reconstruction. However, further randomized clinical trials are needed to confirm these preliminary results.

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.

Aim Little information exists on the impact of cataract surgery on falls and other injuries in Vietnam. The aim of this study was to determine the impact of first and both eye cataract surgery on the number of falls and other injuries among bilateral cataract patients in Ho Chi Minh City, Vietnam. Materials and methods A longitudinal cohort study was conducted involving 413 bilateral cataract patients aged 50+ years. Participants were assessed at three time points: 1 week before, 1–3 months after, and 1 year after first-eye cataract surgery. Visual measures (visual acuity, contrast sensitivity and stereopsis) were taken, and self-reported falls and injury data were collected. A multilevel longitudinal Poisson regression model was used to investigate change in the number of falls after surgery. Results The risk of falls decreased by 78% (incidence-rate ratio [IRR] 0.22, 95% confidence interval [CI] 0.06–0.77; P=0.018) in the year after cataract surgery for participants who had first-eye surgery only and 83% (IRR 0.17, 95% CI 0.04–0.69; P=0.012) for participants who had the second eye operated on compared to before surgery. The risk of falls was three times higher for females than males (IRR 3.13, 95% CI 1.53–6.40; P=0.002). Improved binocular contrast sensitivity was also associated with a decrease in falls (IRR 0.40, 95% CI 0.17–0.97; P=0.042). The prevalence of other injuries also decreased after cataract surgery. Conclusion Cataract surgery reduced the number of falls and other injuries in Vietnam. Contrast sensitivity may be important for ophthalmologists to consider when prioritizing patients for surgery and assessing their fall risk. PMID:24812501

BACKGROUND Various studies have been conducted in many countries to determine the perception/awareness about plastic surgery. The present study assessed the views of college students about plastic surgery. METHODS A questionnaire consisted of nine questions regarding the basic knowledge about plastic surgery was randomly distributed among college students. The students were given 20 minutes to fill out the forms. RESULTS A total of 250 male and 250 female college students were randomly included in the study. The mean age of the male students was 21.1 years as compared to 20.7 years of female students. The top five conditions named were related to hair (89.8%) followed by face scars (88%). The most common procedure named by the students was liposuction (88.2%) followed by hair transplantation. 80.2% of the students opted not to be a plastic surgeon if given an opportunity to select the profession. 33.8% of the students had seen some kinds of plastic surgery operation. Only 5.6% of the students (3.4% male and 2.2% female) had seen some kinds of plastic surgery procedure. 68% of male students and 48% of female students wished to have a plastic surgery procedure sometime in their lives. Majority of the students (88%) got the information from the internet. The second most common source was magazines (85.2%). Majority of the students (53.4%) had an idea of an invisible scar as a result of having a plastic surgery procedure. Only 22% thought to have no scar. Late Michael Jackson was at the top of the list of celebrities having a plastic surgery procedure (97.8%) followed by Nawaz Shariff (92.4%). CONCLUSION Despite the rapid growth of plastic surgery in the last two decades, a large portion of population remains unaware of the spatiality. It is essential to institute programs to educate healthcare consumers and providers about the plastic surgery. PMID:25489513

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.

2017-08-01

Bariatric surgery has emerged as a promising treatment option for weight loss and to counter the metabolic consequences of obesity. Obesity has been linked to a hyperaggregable state, as well as a blunted response to aspirin. This pilot study assessed the hypothesis that bariatric surgery would lead to an improvement in aspirin-induced platelet inhibition and a reduction in platelet aggregability. Fifteen patients scheduled to undergo bariatric surgery were administered two 7-day courses of aspirin 81 mg: the first course administered before surgery and the second was 3 months following surgery. Platelet aggregation was measured before and after each aspirin course using VerifyNow-Aspirin. The primary endpoint was the change in on-treatment aspirin reactive units (ARU) pre- and postsurgery. Data from bariatric surgery study patients were compared to data of normal weighted subjects gathered in a previous study. Roux-en-Y gastric bypass was performed in 80%, and 20% underwent sleeve gastrectomy. The mean starting body mass index (BMI) was 46.9 kg/m 2 . Patients lost on average 24.5 kg, resulting in a postsurgical BMI of 38.5 kg/m 2 . Postbariatric surgery, off-treatment ARU was significantly reduced from presurgery levels (602±59 vs 531±78; P=.035). On-aspirin platelet reactivity was also significantly reduced following surgery (469±60 vs 432±143, P=.03). There was a significant correlation between the extent of weight loss and the degree of improvement in on-aspirin platelet reactivity (r 2 =.49, P=.024). Presurgery on-aspirin platelet reactivity was significantly higher in obese patients compared to normal weighted subjects (469±60 vs 419±52; P=.016) and reduced to the baseline after the surgery (432±63 vs 419±52; P=.54). Aspirin-induced platelet inhibition may be more potent following bariatric surgery. The mechanisms behind this improvement require further investigation. © 2017 John Wiley & Sons Ltd.

Objective Robotic surgery continues to expand in minimally invasive surgery; however, the literature is insufficient to understand the current training process for general surgery residents. Therefore, the objectives of this study were to identify the current approach to and perspectives on robotic surgery training. Methods An electronic survey was distributed to general surgery program directors identified by the Accreditation Council for Graduate Medical Education website. Multiple choice and open-ended questions regarding current practices and opinions on robotic surgery training in general surgery residency programs were used. Results 20 program directors were surveyed, a majority being from medium-sized programs (4–7 graduating residents per year). Most respondents (73.68%) had a formal robotic surgery curriculum at their institution, with 63.16% incorporating simulation training. Approximately half of the respondents believe that more time should be dedicated to robotic surgery training (52.63%), with simulation training prior to console use (84.21%). About two-thirds of the respondents (63.16%) believe that a formal robotic surgery curriculum should be established as a part of general surgery residency, with more than half believing that exposure should occur in postgraduate year one (55%). Conclusion A formal robotics curriculum with simulation training and early surgical exposure for general surgery residents should be given consideration in surgical residency training. PMID:29854454

Background Variability in case exposures has been identified for orthopaedic surgery residents. It is not known if this variability exists for peripheral nerve procedures. Objective The objective of this study was to assess ACGME case log data for graduating orthopaedic surgery, plastic surgery, general surgery, and neurological surgery residents for peripheral nerve surgical procedures and to evaluate intraspecialty and interspecialty variability in case volume. Methods Surgical case logs from 2009 to 2014 for the 4 specialties were compared for peripheral nerve surgery experience. Peripheral nerve case volume between specialties was performed utilizing a paired t test, 95% confidence intervals were calculated, and linear regression was calculated to assess the trends. Results The average number of peripheral nerve procedures performed per graduating resident was 54.2 for orthopaedic surgery residents, 62.8 for independent plastic surgery residents, 84.6 for integrated plastic surgery residents, 22.4 for neurological surgery residents, and 0.4 for surgery residents. Intraspecialty comparison of the 10th and 90th percentile peripheral nerve case volume in 2012 revealed remarkable variability in training. There was a 3.9-fold difference within orthopaedic surgery, a 5.0-fold difference within independent plastic surgery residents, an 8.8-fold difference for residents from integrated plastic surgery programs, and a 7.0-fold difference within the neurological surgery group. Conclusions There is interspecialty and intraspecialty variability in peripheral nerve surgery volume for orthopaedic, plastic, neurological, and general surgery residents. Caseload is not the sole determinant of training quality as mentorship, didactics, case breadth, and complexity play an important role in training. PMID:27168883

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.

Background Persistent postoperative cognitive decline is thought to be a public health problem, but its severity may have been overestimated because of limitations in statistical methodology. This study assessed whether long-term cognitive decline occurred after surgery or illness by using an innovative approach and including participants with early Alzheimer's disease to overcome some limitations. Methods In this retrospective cohort study, three groups were identified from participants tested annually at Washington University's Alzheimer Disease Research Center in St. Louis: those with non-cardiac surgery, illness, or neither. This enabled long-term tracking of cognitive function before and after surgery and illness. The effect of surgery and illness on longitudinal cognitive course was analyzed using a general linear mixed effects model. For participants without initial dementia, time to dementia onset was analyzed using sequential Cox proportional hazards regression. Results Of the 575 participants, 214 were nondemented and 361 had very mild or mild dementia at enrollment. Cognitive trajectories did not differ among the three groups (surgery, illness, control), although demented participants declined more markedly than nondemented. Of the initially nondemented participants, 23% progressed to a clinical dementia rating greater than zero, but this was not more common following surgery or illness. Conclusions The study did not detect long-term cognitive decline independently attributable to surgery or illness nor were these events associated with accelerated progression to dementia. The decision to proceed with surgery in elderly people, including those with early Alzheimer's disease, may presently be made without factoring in the specter of persistent cognitive deterioration.

Summary Introduction Alterations in homeostasis, and a subsequent increased risk for postoperative thromboembolic complications, are observed as a result of open surgery. Additionally, the stress response to surgical trauma precipitates a transient hypercoagulable state as well as inflammation. This study was conducted to evaluate the patterns in postoperative alterations of blood coagulation, and to detect their correlations with inflammatory markers. Patients and methods The study included 50 patients with comparable demographic data, who were randomly assigned to undergo abdominal surgery. No previous coagulation disorders were noted. Blood samples were collected preoperatively and 72 h postoperatively. The following parameters were measured: prothrombin time (PT) and activated partial thromboplastin time (APTT); fibrinogen (FIB), D-dimer (D-D), and C-reactive protein (CRP) levels; and platelet (PLT) count. Prophylactic doses of low molecular weight heparin were administered to all patients. Results The PT mean value significantly changed from 90.38% before surgery to 81.25% after surgery. No statistical difference was observed between APTT values before and after surgery. FIB levels significantly increased from 381.50 mg/dL preoperatively to 462.57 mg/dL postoperatively. Mean D-D levels also significantly increased from 235.54 μg/L preoperatively to 803.59 μg/L postoperatively. PLT count significantly declined after surgery. Mean CRP levels significantly increased from 12.33 mg/L preoperatively to 44.28 mg/L postoperatively. A strong correlation was observed between D-D and C-RP levels after surgery. Conclusion These results indicate that, despite administering an-tithromboembolic prophylaxis, a hypercoagulable state was observed following surgery. This state was enhanced by inflammation.

The STOPP study (Surgical Treatment Outcomes for Patients with Psychiatric Disorders) analyzed variation in rates and types of major surgery by serious mental illness status among patients treated in the Veterans Health Administration (VA). VA patients are veterans of United States military service who qualify for federal care by reason of disability, special service experiences, or poverty. STOPP conducted a secondary data analysis of medical record extracts for seven million VA patients treated Oct 2005-Sep 2009. The retrospective study aggregated inpatient surgery events, comorbid diagnoses, demographics, and postoperative 30-day mortality. Serious mental illness -- schizophrenia, bipolar disorder, posttraumatic stress disorder, or major depressive disorder, was identified in 12 % of VA patients. Over the 4-year study period, 321,131 patients (4.5 %) underwent surgery with same-day preoperative or immediate post-operative admission including14 % with serious mental illness. Surgery patients were older (64 vs. 61 years) and more commonly African-American, unmarried, impoverished, highly disabled (24 % vs 12 % were Priority 1), obese, with psychotic disorder (4.3 % vs 2.9 %). Among surgery patients, 3.7 % died within 30 days postop. After covariate adjustment, patients with pre-existing serious mental illness were relatively less likely to receive surgery (adjusted odds ratios 0.4-0.7). VA patients undergoing major surgery appeared, in models controlling for comorbidity and demographics, to disproportionately exclude those with serious mental illness. While VA preferentially treats the most economically and medically disadvantaged veterans, the surgery subpopulation may be especially ill, potentially warranting increased postoperative surveillance.

Objective A thorough psychological assessment of patients requesting cosmetic surgery can help to protect them from the risk of postoperative dissatisfaction and the onset and/or aggravation of psychiatric disorders. This study seeks to shed more light on why people desire cosmetic surgery and thus help surgeons, psychiatrists, and psychologists to conduct assessments before surgery. Methods In-depth interviews were conducted with 35 subjects who requested cosmetic surgery. The interviews were recorded and transcribed and then analyzed qualitatively with Grounded Theory. Themes and categories were identified and compared in logical order, to build a consistent theoretical model. Results In each interview, we identified one or more recent events that the subjects considered to be contributing factors in their decisions to have cosmetic surgery. We observed that 33 of 35 patients said they sought cosmetic surgery at a time when they were experiencing, or had just experienced, one or more major changes in their bodies or their relationships. Recent life events triggered or strengthened specific psychological needs in the subjects: to cope with the past and with change, attain a consistent identity, find or regain a positive self-image, alter others' perceptions, define themselves in relation to others, or please themselves or others. Patients said that they chose plastic surgery to fulfill one or more of these needs. Conclusions This study identifies the role of recent events in inciting individuals to resort to cosmetic surgery. This factor provides new perspectives for surgeons to understand those patients and opens new avenues for research.

Predictive models of CS-AKI include emergency surgery and patients with haemodynamic instability. Our objective was to evaluate the performance of validated predictive models (Thakar and Demirjian) in elective cardiac surgery and to propose a better score in the case of poor performance. A prospective, multicentre, observational study was designed. Data were collected from 942 patients undergoing cardiac surgery, after excluding emergency surgery and patients with an intraaortic balloon pump. The main outcome measure was CS-AKI defined by the composite of requiring dialysis or doubling baseline creatinine values. Both models showed poor discrimination in elective surgery (Thakar's model, AUROC = 0.57, 95% CI = 0.50-0.64 and Demirjian's model, AUROC= 0.64, 95% CI = 0.58-0.71). We generated a new model whose significant independent predictors were: anaemia, age, hypertension, obesity, congestive heart failure, previous cardiac surgery and type of surgery. It classifies patients with scores 0-3 as low risk (< 5%), scores 4-7 as medium risk (up to 15%) and scores > 8 as high risk (>30%) of developing CS-AKI with a statistically significant correlation (p <0.001). Our model reflects acceptable discriminatory ability (AUC = 0.72, 95% CI = 0.66-0.78) which is significantly better than Thakar and Demirjian's models (p<0.01). We developed a new simple predictive model of CS-AKI in elective surgery based on available preoperative information. Our new model is easy to calculate and can be an effective tool for communicating risk to patients and guiding decision-making in the perioperative period. The study requires external validation.

Despite promotional measures at a national level, female surgeons account for only 10% of the consultant workforce in the United Kingdom. With rising proportions of female medical graduates, it is important that surgery continues to recruit the most able candidates regardless of sex. This study investigates the differing perceptions of surgical careers among recent medical school graduates and identifies factors discouraging female doctors from pursuing a career in surgery. Newly qualified graduates from the University of Nottingham Medical School, Nottingham, UK, were invited to complete a nonmandatory questionnaire investigating career intentions and factors influencing this. Two hundred and eight questionnaires were returned (a 66% response rate). Male respondents were significantly more likely to rate surgery as an attractive or very attractive career (P = .0116). Overall, only 33 (25%) female doctors expressed interest in a surgical career as opposed to 33 (42%) male doctors (P = .010). Frequently cited reasons included no interest in surgery itself (21%) and negative attitudes toward women in surgery among the surgical teams (18%). Irrespective of career interests, 59% of male and 68% of female respondents believed surgery was not a career welcoming women (P = .186). Reasons included difficulty maintaining family life, limited flexible training, and lack of role models. This study identifies significant sex differences in the perception of surgical careers. The majority believes surgery does not welcome female trainees. Future strategies to promote surgery must address attitudes and behaviors in both sexes while taking active steps to support female surgeons during their training and in the workplace.

This study aims to demonstrate the importance of the opportunity cost in using da Vinci robotic surgery, assisted by a comprehensive review of the literature to determine the differences in the total cost of surgery and operative time in traditional laparoscopic surgery and da Vinci robotic surgery. We identified the studies comparing the use of traditional laparoscopic surgery with robotics during the period 2002-2012 in the electronic economic evaluation databases, and another electronic search was performed for publications by Spanish hospitals in the same period to calculate the opportunity cost. A meta-analysis of response variables considering the total cost of the intervention and surgical time was completed using the items selected in the first revision, and their differences were analyzed. We then calculated the opportunity cost represented by these time differences using the data obtained from the studies in the second review of the literature. Nine items were selected in the first review and three in the second. Traditional laparoscopic surgery has a lower cost than the da Vinci (p < 0.00001). Robotic surgery takes longer (8.0-65.5 min) than traditional surgery (p < 0.00001), and this difference represents an average opportunity cost for robot use of € 489.98, with a unit cost factor/time which varies according to the pathology dealt with, from € 8.2 to 18.7/min. The opportunity cost is a quantity that must be included in the total cost of using a surgical technology within an economic cost analysis in the context of an economic evaluation.

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.

Preoperative functional capacity is considered an important risk factor for cardiovascular and other complications of major non-cardiac surgery. Nonetheless, the usual approach for estimating preoperative functional capacity, namely doctors' subjective assessment, may not accurately predict postoperative morbidity or mortality. 3 possible alternatives are cardiopulmonary exercise testing; the Duke Activity Status Index, a standardised questionnaire for estimating functional capacity; and the serum concentration of N-terminal pro-B-type natriuretic peptide (NT pro-BNP), a biomarker for heart failure and cardiac ischaemia. The Measurement of Exercise Tolerance before Surgery (METS) Study is a multicentre prospective cohort study of patients undergoing major elective non-cardiac surgery at 25 participating study sites in Australia, Canada, New Zealand and the UK. We aim to recruit 1723 participants. Prior to surgery, participants undergo symptom-limited cardiopulmonary exercise testing on a cycle ergometer, complete the Duke Activity Status Index questionnaire, undergo blood sampling to measure serum NT pro-BNP concentration and have their functional capacity subjectively assessed by their responsible doctors. Participants are followed for 1 year after surgery to assess vital status, postoperative complications and general health utilities. The primary outcome is all-cause death or non-fatal myocardial infarction within 30 days after surgery, and the secondary outcome is all-cause death within 1 year after surgery. Both receiver-operating-characteristic curve methods and risk reclassification table methods will be used to compare the prognostic accuracy of preoperative subjective assessment, peak oxygen consumption during cardiopulmonary exercise testing, Duke Activity Status Index scores and serum NT pro-BNP concentration. The METS Study has received research ethics board approval at all sites. Participant recruitment began in March 2013, and 1-year follow-up is expected to finish in 2016. Publication of the results of the METS Study is anticipated to occur in 2017. Published by the BMJ Publishing Group Limited.

Study Design: A multicenter, retrospective cohort study. Objective: To evaluate clinical outcomes in patients with reintubation after anterior cervical spine surgery. Methods: A total of 8887 patients undergoing anterior cervical spine surgery were enrolled in the AOSpine North America Rare Complications of Cervical Spine Surgery study. Patients with or without complications after surgery were included. Demographic and surgical information were collected for patients with reintubation. Patients were evaluated using a variety of assessment tools, including the modified Japanese Orthopedic Association scale, Nurick score, Neck Disability Index, and Short Form-36 Health Survey. Results: Nine cases of postoperative reintubation were identified. The total prevalence of this complication was 0.10% and ranged from 0% to 0.59% across participating institutions. The time to development of airway symptoms after surgery was within 24 hours in 6 patients and between 5 and 7 days in 3 patients. Although 8 patients recovered, 1 patient died. At final follow-up, patients with reintubation did not exhibit significant and meaningful improvements in pain, functional status, or quality of life. Conclusions: Although the prevalence of reintubation was very low, this complication was associated with adverse clinical outcomes. Clinicians should identify their high-risk patients and carefully observe them for up to 2 weeks after surgery. PMID:28451501

Study Objective To evaluate if the administration of intraperitoneal bupivacaine decreased postoperative pain in patients undergoing minimally invasive gynecologic and gynecologic cancer surgery. Design Retrospective cohort study (Canadian Task Force classification II-3). Setting University-based gynecologic oncology practice operating at a tertiary medical center. Patients All patients on the gynecologic oncology service undergoing minimally invasive surgery between September 2011 and June 2013. Interventions Starting August 2012, intraperitoneal administration of .25% bupivacaine was added to all minimally invasive surgeries. These patients were compared with historical control subjects who had surgery between September 2011 and July 2012 but did not receive intraperitoneal bupivacaine. Measurements and Main Results One-hundred thirty patients were included in the study. The patients who received intraperitoneal bupivacaine had lower median narcotic use on the day of surgery and the first postoperative day compared with those who did not receive intraperitoneal bupivacaine (day 0: 7.0 mg morphine equivalents vs 11.0 mg, p = .007; day 1: .3 mg vs 1.7 mg, p = .0002). The median patient-reported pain scores were lower on the day of surgery in the intraperitoneal bupivacaine group (2.7 vs 3.2, p = .05) Conclusions The administration of intraperitoneal bupivacaine was associated with improved postoperative pain control in patients undergoing minimally invasive gynecologic and gynecologic cancer surgery and should be further evaluated in a prospective study.

In South Korea, the number of severely obese patients has increased. An economic study comparing bariatric surgery with nonsurgical interventions has not been published for Asia. This study was conducted to evaluate the cost effectiveness of bariatric surgery as compared to nonsurgical interventions for severe obese Korean people. We used the Markov model to compare the lifetime expected costs and quality-adjusted life years (QALYs) between bariatric surgery and nonsurgical interventions from Korean Healthcare system perspectives. Our target cohort consisted of severe obese people defined as having a body mass index of 30-<40 kg/m(2) in South Korea. The starting age of the cohort was 30 years old, and the cycle length was 1 year. Nonsurgical interventions included a physician visit, exercise, diet, and pharmacotherapy. A discount of 5 % was applied in cost and QALY. The incremental cost-effectiveness ratio (ICER) of bariatric surgery compared to nonsurgery interventions was calculated. The cost-utility analysis study indicated that bariatric surgery had US$1,522 incremental costs and 0.86 incremental QALYs as compared to nonsurgical interventions. Through the base case analysis, ICER was US$1,771/QALY. The sensitivity analyses were performed using a variety of assumptions, and the robustness of the study results was also demonstrated. The study indicated that bariatric surgery was a cost-effective alternative to nonsurgical interventions over a lifetime, providing substantial lifetime benefits for severely obese Korean people.

A certain weight gain occurs after obesity surgery compared to the lower weight usually observed between 18 and 24 months postsurgery. The objective of this study was to evaluate weight regain in patients submitted to gastric bypass over a 5-year follow-up period. A longitudinal prospective study was conducted on 782 obese patients of both genders. Only patients with at least 2 years of surgery were included. The percentage of excess body mass index (BMI) loss at 24, 36, 48, and 60 months postsurgery was compared to the measurements obtained at 18 months after surgery. Surgical therapeutic failure was also evaluated. Percent excess BMI loss was significant up to 18 months postsurgery (p < 0.001), with a mean difference in BMI of 1.06 kg/m2 compared to 12 months postsurgery. Percent BMI loss was no longer significant after 24 months, and weight regain became significant within 48 months after surgery (p < 0.01). Among the patients who presented weight regain, a mean 8% increase was observed within 60 months compared to the lowest weight obtained at 18 months after surgery. The percentage of surgical failure was higher in the superobese group at all times studied, reaching 18.8% at 48 months after surgery. Weight regain was observed within 24 months after surgery in approximately 50% of patients. Both weight regain and surgical failure were higher in the superobese group. Studies in regard to metabolic and hormonal mechanisms underlying weight regain might elucidate the causes of this finding.

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.

To evaluate the evidence for the effectiveness of sham surgery in orthopedics by conducting a systematic review of literature. Systematic searches were conducted on Biomed Central, BMJ.com, CINAHL, the Cochrane Library, NLM Central Gateway, OVID, ProQuest (Digital Dissertations), PsycInfo, PubMed/Medline, ScienceDirect and Web of Science. Secondary searching (PEARLing) was undertaken, whereby reference lists of the selected articles were reviewed for additional references not identified in the primary search. All randomized controlled trials comparing surgery versus sham surgery in orthopedics were included. Data were extracted and methodological quality was assessed by two reviewers using the Critical Review Form-Quantitative Studies. Levels of scientific evidence, based on the direction of outcomes of the trials, were established following the Australian National Health and Medical Research Council (NHMRC) Hierarchy of Evidence (Australian National Health and Medical Research Council, 1999). This review includes six randomized controlled trials (RCTs) involving 277 subjects. All six studies were rated as very good on methodological quality. Heterogeneity across the studies, with respect to participants, interventions evaluated, and outcome measures used, prevented meta-analyses. Narrative synthesis of results, based on effect size, demonstrated that sham surgery in orthopedics was as effective as actual surgery in reducing pain and improving disability. This review suggests that sham surgery has shown to be just as effective as actual surgery in reducing pain and disability; however, care should be taken to generalize findings because of the limited number of studies. © 2016 American Academy of Pain Medicine.

Influences on choice of surgery as a career: a study of consecutive cohorts in a medical school.

PubMed

Sobral, Dejano T

2006-06-01

To examine the differential impact of person-based and programme-related features on graduates' dichotomous choice between surgical or non-surgical field specialties for first-year residency. A 10-year cohort study was conducted, following 578 students (55.4% male) who graduated from a university medical school during 1994-2003. Data were collected as follows: at the beginning of medical studies, on career preference and learning frame; during medical studies, on academic achievement, cross-year peer tutoring and selective clinical traineeship, and at graduation, on the first-year residency selected. Contingency and logistic regression analyses were performed, with graduates grouped by the dichotomous choice of surgery or not. Overall, 23% of graduates selected a first-year residency in surgery. Seven time-steady features related to this choice: male sex, high self-confidence, option of surgery at admission, active learning style, preference for surgery after Year 1, peer tutoring on clinical surgery, and selective training in clinical surgery. Logistic regression analysis, including all features, predicted 87.1% of the graduates' choices. Male sex, updated preference, peer tutoring and selective training were the most significant predictors in the pathway to choice. The relative roles of person-based and programme-related factors in the choice process are discussed. The findings suggest that for most students the choice of surgery derives from a temporal summation of influences that encompass entry and post-entry factors blended in variable patterns. It is likely that sex-unbiased peer tutoring and selective training supported the students' search process for personal compatibility with specialty-related domains of content and process.

Bariatric surgery orientation sessions are often the first point of contact and a recommended component of pre-bariatric surgery assessment. Self-removal rates after bariatric program orientation are as high as 25 % despite the proven efficacy of this procedure. The objective of this study was to identify factors contributing to patient self-removal after orientation using a mixed method approach. Patients who attended the Toronto Western Hospital Bariatric Surgery Program orientation between 2012 and 2013 and then self-removed from the program (N = 216) were included in the study. Subjects were interviewed via telephone using a semi-structured interview guide, generating both quantitative and qualitative data. Factors leading to discontinuation were rated on a five-point Likert scale. Qualitative data was analyzed using constant comparative methodology. The response rate was 59 % with a 40.7 % completion rate (N = 88). Concerns about potential surgical risks and complications and the ability to adapt to changes in eating and drinking post-operatively were identified as the top two factors for patients' self-removal from the program. Thematic analysis uncovered 11 major themes related to patient self-removal. Unexpected themes include perceived personal suitability for the surgery, family impact of surgery, miscommunication with the family physician, and fears related to the orientation information. This is one of the first studies examining barriers to bariatric surgery in the pre-operative setting and offers new insights into the reasons patients self-remove from bariatric surgery programs. This study may inform bariatric orientation program changes resulting in improved access to this effective surgical intervention.

Morbid obesity is strongly associated with non-alcoholic fatty liver disease. The effects of bariatric surgery on liver tests an histological abnormalities after weight loss are controversial. To review the literature on the prevalence of non-alcoholic fatty liver disease in patients with morbid obesity with respect to laboratory and histopathological parameters and the effect of weight loss on these parameters after bariatric surgery. Standard liver tests do not seem to be a sensitive tool for the assessment and follow-up of non-alcoholic fatty liver disease in obesity. In nearly all patients with morbid obesity, histological abnormalities reflecting non-alcoholic fatty liver disease are present. Bariatric surgery in these patients will decrease the grade of steatosis. However, there are some concerns about the effect of bariatric surgery on hepatic inflammation and fibrosis. In particular, older follow-up studies reported negative results as opposed to more recent studies, which also showed improvement in hepatic inflammation and fibrosis. Unfortunately, most studies had limitations because of the selection of patients. Despite limitations in many studies, bariatric surgery seems to be a promising treatment in patients with obesity presenting with non-alcoholic fatty liver disease.

Recent reports have highlighted the progressive increase in the incidence of ulnar collateral ligament (UCL) injuries to the elbow in baseball players of all levels. However, knowledge of the incidence and other epidemiological factors regarding UCL injuries, specifically in college baseball players, is currently lacking. To evaluate, over a period of 1 year, the incidence of UCL injuries requiring surgery in National Collegiate Athletic Association (NCAA) Division I baseball programs. Descriptive epidemiology study. A total of 155 Division I collegiate baseball programs agreed to participate in the study. Demographics (position, year, background [location of high school]) for all players on these rosters were obtained from public websites. At the conclusion of the 2017 collegiate baseball season, the athletic trainer for each program entered anonymous, detailed information on injured players through an electronic survey into a secured database. All 155 teams enrolled in the study completed the electronic survey. Of the 5295 collegiate baseball players on these rosters, 134 underwent surgery for an injured UCL (2.5% of all eligible athletes), resulting in a team surgery rate of 0.86 per program for 1 year. These 134 players came from 88 teams, thus 56.8% of the study teams underwent at least 1 surgery during the year. The surgery rate was 2.5 per 100 player-seasons for all players and was significantly higher among pitchers (4.4/100 player-seasons) than nonpitchers (0.7/100 player-seasons). The surgery rate was also significantly higher in underclassmen (3.1/100 player-seasons among freshmen and sophomores) than upperclassmen (1.9/100 player-seasons among juniors and seniors) (incidence rate ratio, 1.7; 95% CI, 1.1-2.4). Players from traditionally warm-weather states did not undergo UCL surgery at a significantly different rate from players from traditionally cold-weather states (2.7/100 player-seasons vs 2.1/100 player-seasons, respectively). Nearly half of surgeries (48.5%) were performed during the baseball season. The incidence of UCL surgeries in NCAA Division I collegiate baseball players represents substantial morbidity to this young athletic population. Risk factors for injuries requiring surgery include being a pitcher and an underclassman. Awareness of these factors should be considered in injury prevention programs. Furthermore, this initial study can serve as a foundation for tracking these surgical injuries in future years and then identifying trends over time.

Ultrasound-guided breast-sparing surgery to improve cosmetic outcomes and quality of life. A prospective multicentre randomised controlled clinical trial comparing ultrasound-guided surgery to traditional palpation-guided surgery (COBALT trial)

PubMed Central

2011-01-01

Background Breast-conserving surgery for breast cancer was developed as a method to preserve healthy breast tissue, thereby improving cosmetic outcomes. Thus far, the primary aim of breast-conserving surgery has been the achievement of tumour-free resection margins and prevention of local recurrence, whereas the cosmetic outcome has been considered less important. Large studies have reported poor cosmetic outcomes in 20-40% of patients after breast-conserving surgery, with the volume of the resected breast tissue being the major determinant. There is clear evidence for the efficacy of ultrasonography in the resection of nonpalpable tumours. Surgical resection of palpable breast cancer is performed with guidance by intra-operative palpation. These palpation-guided excisions often result in an unnecessarily wide resection of adjacent healthy breast tissue, while the rate of tumour-involved resection margins is still high. It is hypothesised that the use of intra-operative ultrasonography in the excision of palpable breast cancer will improve the ability to spare healthy breast tissue while maintaining or even improving the oncological margin status. The aim of this study is to compare ultrasound-guided surgery for palpable tumours with the standard palpation-guided surgery in terms of the extent of healthy breast tissue resection, the percentage of tumour-free margins, cosmetic outcomes and quality of life. Methods/design In this prospective multicentre randomised controlled clinical trial, 120 women who have been diagnosed with palpable early-stage (T1-2N0-1) primary invasive breast cancer and deemed suitable for breast-conserving surgery will be randomised between ultrasound-guided surgery and palpation-guided surgery. With this sample size, an expected 20% reduction of resected breast tissue and an 18% difference in tumour-free margins can be detected with a power of 80%. Secondary endpoints include cosmetic outcomes and quality of life. The rationale, study design and planned analyses are described. Conclusion The COBALT trial is a prospective, multicentre, randomised controlled study to assess the efficacy of ultrasound-guided breast-conserving surgery in patients with palpable early-stage primary invasive breast cancer in terms of the sparing of breast tissue, oncological margin status, cosmetic outcomes and quality of life.

Observational studies are common research strategies in hand surgery. The case-cohort design offers an efficient and resource-friendly method for risk assessment and outcomes analysis. Case-cohorts remain underrepresented in upper extremity research despite several practical and economic advantages over case-control studies. This report outlines the purpose, utility, and structure of the case-cohort design and offers a sample research question to demonstrate its value to risk estimation for adverse surgical outcomes. The application of well-designed case-cohort studies is advocated in an effort to improve the quality and quantity of observational research evidence in hand and upper extremity surgery.

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.

Speech-correcting surgeries (pharyngoplasty) are performed to correct velopharyngeal insufficiency (VPI). This study aimed to analyze the need for speech-correcting surgery in children with isolated cleft palate (ICP) and to determine differences among cleft extent, gender, and primary technique used. In addition, we assessed the timing and number of secondary procedures performed and the incidence of operated fistulas. Retrospective medical chart review study from hospital archives and electronic records. These comprised the 423 consecutive nonsyndromic children (157 males and 266 females) with ICP treated at the Cleft Palate and Craniofacial Center of Helsinki University Hospital during 1990 to 2016. The total incidence of VPI surgery was 33.3% and the fistula repair rate, 7.8%. Children with cleft of both the hard and soft palate (n = 300) had a VPI secondary surgery rate of 37.3% (fistula repair rate 10.7%), whereas children with only cleft of the soft palate (n = 123) had a corresponding rate of 23.6% (fistula repair rate 0.8%). Gender and primary palatoplasty technique were not considered significant factors in need for VPI surgery. The majority of VPI surgeries were performed before school age. One fifth of patients receiving speech-correcting surgery had more than one subsequent procedure. The need for speech-correcting surgery and fistula repair was related to the severity of the cleft. Although the majority of the corrective surgeries were done before the age of 7 years, a considerable number were performed at a later stage, necessitating long-term observation.

Children with congenital heart disease (CHD) often require noncardiac surgery. We compared outcomes following open and laparoscopic intraabdominal surgery among children with and without CHD. We performed a retrospective cohort study using the 2013-2015 National Surgical Quality Improvement Project-Pediatrics. We matched 45,012 children <18years old who underwent laparoscopic surgery to 45,012 children who underwent open surgery. We determined the associations between laparoscopic (versus open) surgery and 30-day mortality, in-hospital mortality, 30-day morbidity, and postoperative length-of-stay. Among children with minor CHD, laparoscopic surgery was associated with lower 30-day mortality (Odds Ratio [OR] 0.34 [95% Confidence Interval 0.15-0.79]), inhospital mortality (OR 0.42 [0.22-0.81]) and 30-day morbidity (OR 0.61 [0.50-0.73]). As CHD severity increased, this benefit of laparoscopic surgery decreased for 30-day morbidity (ptrend=0.01) and in-hospital mortality (ptrend=0.05), but not for 30-day mortality (ptrend=0.27). Length-of-stay was shorter for laparoscopic approaches for children at cost of higher readmissions. On subgroup analysis, laparoscopy was associated with lower odds of postoperative blood transfusion in all children. Intraabdominal laparoscopic surgery compared to open surgery is associated with decreased morbidity in patients with no CHD and lower morbidity and mortality in patients with minor CHD, but not in those with more severe CHD.

Robots have been successfully used in commercial industry and have enabled humans to perform tasks which are repetitive, dangerous and requiring extreme force. Their role has evolved and now includes many aspects of surgery to improve safety and precision. Orthopaedic surgery is largely performed on bones which are rigid immobile structures which can easily be performed by robots with great precision. Robots have been designed for use in orthopaedic surgery including joint arthroplasty and spine surgery. Experimental studies have been published evaluating the role of robots in arthroscopy and trauma surgery. In this article, we will review the incorporation of robots in orthopaedic surgery looking into the evidence in their use. PMID:28534472

Predictive risk models help improve decision making, information to our patients and quality control comparing results between surgeons and between institutions. The use of these models promotes competitiveness and led to increasingly better results. All these virtues are of utmost importance when the surgical operation entails high-risk. Although proximal aortic surgery is less frequent than other cardiac surgery operations, this procedure itself is more challenging and technically demanding than other common cardiac surgery techniques. The aim of this study is to review the current status of predictive risk models for patients who undergo proximal aortic surgery, which means aortic root replacement, supracoronary ascending aortic replacement or aortic arch surgery.

Orthopedic and plastic surgery residents receive unique training yet often compete for similar hand surgery fellowships. This study compared didactic hand surgery training during orthopedic and plastic surgery residency. The Plastic Surgery In-Service Training Exam and Orthopaedic In-Training Examination were analyzed for hand content for the years 2009 to 2013. Topics were categorized with the content outline for the Surgery of the Hand Examination. Differences were elucidated by means of Fisher's exact test. Relative to the Orthopaedic In-Training Examination, the Plastic Surgery In-Service Training Exam had greater hand representation (20.3 percent versus 8.1 percent; p < 0.001) with more annual hand questions (40 ± 3 versus 24 ± 2; p < 0.001). The Plastic Surgery Exam questions had more words, were less often level I-recall type, and were less often image-based. The questions focused more on finger and hand/palm anatomy, whereas the Orthopaedic examination was more wrist-focused. The Plastic Surgery Exam emphasized wound management and muscle/tendon injuries, but underemphasized fractures/dislocations. References differed, but Journal of Hand Surgery (American Volume) and Green's Operative Hand Surgery were common on both examinations. The Plastic Surgery Exam had a greater publication lag for journal references (10.7 ± 0.5 years versus 9.0 ± 0.6; p = 0.035). Differences in didactic hand surgery training are elucidated for plastic surgery and orthopedic residents. Deficiencies in the Plastic Surgery In-Service Training Exam hand curriculum relative to the Orthopaedic In-Training Examination may underprepare plastic surgeons for the Surgery of the Hand Examination. These data may assist future modifications to hand surgery training in the United States.

Multi-level cervical degeneration of the spine is a common clinical pathology that is often repaired by anterior cervical discectomy and fusion (ACDF). The aim of this study was to investigate the kinematics of the cervical spine after hybrid surgery compared with 2-level ACDF. Five freshly frozen, unembalmed whole human cadavers were used including 3 males and 2 females with a mean age of 51 ± 8 years. After evaluating the intact spine for range of motion (ROM), sagittal alignment and instantaneous center of rotation (ICR), each cadaver underwent 4 consecutive surgeries: 2-level artificial disc replacement (ADR) from C4 to C6 (ADR surgery); 2-level ACDF from C4 to C6 (ACDF surgery); hybrid C4-5 ACDF and C5-6 ADR (ACDF+ADR surgery); and hybrid C4-5 ADR and C5-6 ACDF (ADR+ACDF surgery). The ROM and ICR of adjacent intact segments (C3-4; C6-7), and whole sagittal alignment were revaluated. Two-level ACDF resulted in increased ROM at C3-4 and C6-7 compared with intact spine. ROM was significantly different to intact spine using ACDF surgery at C3-C4 and C6-C7 and ROM was increased with ACDF+ADR surgery at C6-C7 (all P<0.05). No improvement in sagittal alignment was observed with any approach. The localization of the ICR shifted upwards and anteriorly at C3-C4 after reconstruction. ICR changes at C3-C4 were greatest for ADR+ACDF surgery and were significantly different to ACDF surgery (P<0.05), but not between ADR surgery and ACDF+ADR surgery. At C6-C7, the ICR was more posterior and superior than in the intact condition. The greatest change in ICR was observed in ACDF surgery at the C6-C7 level, significantly different from the other groups (P<0.05). For 2-level reconstruction, hybrid surgery and ADR did not alter ROM and minimally changed ICR at the adjacent-level. The type of surgery had a significant impact on the ICR location. This suggests that hybrid surgery may be a viable option for 2-level cervical surgery.

Retrospective analysis of a prospective, multicenter cohort study. To estimate the added effect of surgical fusion as compared to decompression surgery alone in symptomatic lumbar spinal stenosis patients with spondylolisthesis. The optimal surgical management of lumbar spinal stenosis patients with spondylolisthesis remains controversial. Patients of the Lumbar Stenosis Outcome Study with confirmed DLSS and spondylolisthesis were enrolled in this study. The outcomes of this study were Spinal Stenosis Measure (SSM) symptoms (score range 1-5, best-worst) and function (1-4) over time, measured at baseline, 6, 12, 24, and 36 months follow-up. In order to quantify the effect of fusion surgery as compared to decompression alone and number of decompressed levels, we used mixed effects models and accounted for the repeated observations in main outcomes (SSM symptoms and SSM function) over time. In addition to individual patients' random effects, we also fitted random slopes for follow-up time points and compared these two approaches with Akaike's Information Criterion and the chi-square test. Confounders were adjusted with fixed effects for age, sex, body mass index, diabetes, Cumulative Illness Rating Scale musculoskeletal disorders, and duration of symptoms. One hundred thirty-one patients undergoing decompression surgery alone (n = 85) or decompression with fusion surgery (n = 46) were included in this study. In the multiple mixed effects model the adjusted effect of fusion compared with decompression alone surgery on SSM symptoms was 0.06 (95% confidence interval: -0.16-0.27) and -0.07 (95% confidence interval: -0.25-0.10) on SSM function, respectively. Among the patients with degenerative lumbar spinal stenosis and spondylolisthesis our study confirms that in the two groups, decompression alone and decompression with fusion, patients distinctively benefited from surgical treatment. When adjusted for confounders, fusion surgery was not associated with a more favorable outcome in both SSM scores as compared to decompression alone surgery. 3.

Overutilization and underutilization of operating rooms - insights from behavioral health care operations management.

The planning of surgery durations is crucial for efficient usage of operating theaters. Both planning too long and too short durations for surgeries lead to undesirable consequences, e.g. idle time, overtime, or rescheduling of surgeries. We define these consequences as operating room inefficiency. The overall objective of planning surgery durations is to minimize expected operating room inefficiency, since surgery durations are stochastic. While most health care studies assume economically rational behavior of decision makers, experimental studies have shown that decision makers often do not act according to economic incentives. Based on insights from health care operations management, medical decision making, behavioral operations management, as well as empirical observations, we derive hypotheses that surgeons' behavior deviates from economically rational behavior. To investigate this, we undertake an experimental study where experienced surgeons are asked to plan surgeries with uncertain durations. We discover systematic deviations from optimal decision making and offer behavioral explanations for the observed biases. Our research provides new insights to tackle a major problem in hospitals, i.e. low operating room utilization going along with staff overtime.

Piezoelectric technology in otolaryngology, and head and neck surgery: a review.

PubMed

Meller, C; Havas, T E

2017-07-01

Piezoelectric technology has existed for many years as a surgical tool for precise removal of soft tissue and bone. The existing literature regarding its use specifically for otolaryngology, and head and neck surgery was reviewed. The databases Medline, the Cochrane Central Register of Controlled Trials, PubMed, Embase and Cambridge Scientific Abstracts were searched. Studies were selected and reviewed based on relevance. Sixty studies were identified and examined for evidence of benefits and disadvantages of piezoelectric surgery and its application in otolaryngology. The technique was compared with traditional surgical methods, in terms of intra-operative bleeding, histology, learning curve, operative time and post-operative pain. Piezoelectric technology has been successfully employed, particularly in otology and skull base surgery, where its specific advantages versus traditional drills include a lack of 'blunting' and tissue selectivity. Technical advantages include ease of use, a short learning curve and improved visibility. Its higher cost warrants consideration given that clinically significant improvements in operative time and morbidity have not yet been proven. Further studies may define the evolving role of piezoelectric surgery in otolaryngology, and head and neck surgery.

Pancreatic surgery.

To summarize published research on pancreatic surgery over the past year. A number of studies aiming to reduce the costs associated with pancreatic surgery were reported. Retrospective analyses confirmed previous findings that neither the routine use of pancreatic duct stents decreases the rate of fistula formation nor does placement of a drain at the time of surgery change the morbidity in patients who develop one. Minimally invasive approaches, both laparoscopic and robot-assisted, are being performed more frequently to remove pancreatic cancers. A randomized trial confirmed that reinforcement of stapled closure during distal pancreatectomy reduces the rate of fistula formation. Controversy remains over whether small pancreatic neuroendocrine tumors need to be surgically resected or can be treated nonoperatively. Patients with chronic pancreatitis should be screened thoroughly before being offered surgical treatment; two studies reported preoperative factors that can be used to identify those most likely to experience pain relief. Studies published on pancreatic surgery last year focused on a wide-range of topics. The morbidity and mortality of patients undergoing pancreatic surgery continues to improve, and we anticipate that incorporation of these new findings will lead to even better outcomes.

In this study we aimed to define the rate of early surgery for Crohn's disease and to identify risk factors associated with early surgery as a basis for subsequent studies of early intervention in Crohn's disease. We assembled a retrospective cohort of patients with Crohn's disease diagnosed between 1991 and 1997 and followed for at least 3 yr, who were identified in 16 community and referral-based practices in New England. Chart review was performed for each patient. Details of baseline demographic and disease features were recorded. Surgical history including date of surgery, indication, and procedure were also noted. Risk factors for early surgery (defined as major surgery for Crohn's disease within 3 yr of diagnosis, exclusive of major surgery at time of diagnosis) were identified by univariate analysis. Multiple logistic regression was used to identify independent risk factors. Of 345 eligible patients, 69 (20.1%) required surgery within 3 yr of diagnosis, excluding the 14 patients (4.1%) who had major surgery at the time of diagnosis. Overall, the interval between diagnosis and surgery was short; one half of all patients who required surgery underwent operation within 6 months of diagnosis. Risk factors identified by univariate analysis as significantly associated with early surgery included the following: smoking; disease of small bowel without colonic involvement; nausea and vomiting or abdominal pain on presentation; neutrophil count; and steroid use in the first 6 months. Disease localized to the colon only, blood in the stool, use of 5-aminosalicylate, and lymphocyte count were inversely associated with risk of early surgery. Logistic regression confirmed independent associations with smoking as a positive risk factor and involvement of colon without small bowel as a negative risk factor for early surgery. The rate of surgery is high in the first 3 yr after diagnosis of Crohn's disease, particularly in the first 6 months. These results suggest that improved risk stratification and potent therapies with rapid onset of action are needed to modify the natural history of Crohn's disease.

To conduct a systematic review to evaluate the evidence of the use of incentive spirometry (IS) for the prevention of postoperative pulmonary complications and for the recovery of pulmonary function in patients undergoing abdominal, cardiac and thoracic surgeries. Searches were performed in the following databases: Medline, Embase, Web of Science, PEDro and Scopus to select randomized controlled trials which the IS was used in pre- and/or post-operative in order to prevent postoperative pulmonary complications and/or recover lung function after abdominal, cardiac and thoracic surgery. Two reviewers independently assessed all studies. In addition, the studies quality was assessed using the PEDro scale. Thirty studies were included (14 abdominal, 13 cardiac and 3 thoracic surgery; n=3,370 patients). In the analysis of the methodological quality, studies achieved a PEDro average score of 5.6, 4.7 and 4.8 points in abdominal, cardiac and thoracic surgeries, respectively. Five studies (3 abdominal, 1 cardiac and 1 thoracic surgery) compared the effect of the IS with control group (no intervention) and no difference was detected in the evaluated outcomes. There was no evidence to support the use of incentive spirometry in the management of surgical patients. Despite this, the use of incentive spirometry remains widely used without standardization in clinical practice.

There are several different opinions regarding the improvements seen on the transverse plane after soft tissue surgery alone in independently ambulant patients with cerebral palsy. We performed a meta-analysis using data from previous studies to identify the effects of soft tissue surgery alone on pelvic and hip rotation in children with spastic diplegia. We conducted a pilot study to evaluate the improvement in pelvic and hip rotation after muscle-tendon lengthening surgery in children with spastic diplegia. We also searched EMBASE and PubMed and selected 2 previous studies using the same test conditions with kinematic data on the pelvis and hip joints. A meta-analysis of the results of these 3 studies, including this pilot study, was then performed. The meta-analysis results showed an external rotation decrease (p = 0.005) in the mean difference of pelvic rotation of -3.61 (95% confidence interval [CI], -6.13 to -1.09) and a mean difference in hip rotation of 6.60 (95% CI, 3.34 to 9.86), indicating a significant increase in the hip external rotation after surgery (p < 0.001). In independently community-ambulant pediatric patients with spastic diplegia, pelvic retraction and hip internal rotation could be improved after soft tissue surgery.

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.

Over recent years, minimally invasive hepatic resections have increasingly been reported in the literature. Even though hepatic surgery is still considered a challenge for surgeons due to its technical difficulties and high morbidity, the development and spread of robotic surgery has highlighted a new interest, which has induced a rapid dissemination of robotic approaches for hepatic pathologies. This article presents a systematic review of the literature regarding robotic hepatectomy in order to assess the safety and feasibility of robotic hepatic surgery. All eligible studies in robotic liver surgery which were published between January 2001 and January 2016 were reviewed systematically. Only series of ten patients and more were chosen in order to consider the experience of high-volume centers. In case of multiple articles on the same centers, the study including the largest number of patients was considered for the study. Overall, 18 studies, involving a total of 572 robotic liver resection (RLR) were finally analyzed. All articles in this review demonstrate that robotic liver surgery must be performed by surgeons trained in open liver surgery and skilled in minimally invasive techniques. RLR and laparoscopic liver resection (LLR) were comparable in terms of safety, feasibility, and outcome for hepatectomies. However, RLR is more expensive than LLR. Further studies are required before any final conclusion can be drawn.

To our knowledge, an observational study on the remission of type 2 diabetes mellitus (T2DM) after different types of bariatric surgery based on data from general practice has not been carried out. To assess the effect of different types of bariatric surgery in patients with T2DM on diabetes remission compared with matched control patients, and the effect of the type of bariatric surgery on improvement of glycemic control and related clinical parameters. A retrospective cohort study conducted from May 2013 to May 2014 within the Clinical Practice Research Datalink involving 2978 patients with a record of bariatric surgery (2005-2012) and a body mass index (calculated as weight in kilograms divided by height in meters squared) of 35 or greater. We identified 569 patients with T2DM and matched them to 1881 patients with diabetes without bariatric surgery. Data on the use of medication and laboratory results were evaluated. Bariatric surgery, stratified by type of surgery (gastric banding, Roux-en-Y gastric bypass, sleeve gastrectomy, or other/unknown). Remission of T2DM (complete discontinuation of glycemic therapy, accompanied with a subsequently recorded hemoglobin A1c level<6.0%). Among patients undergoing bariatric surgery, we found a prevalence of 19.1% for T2DM. Per 1000 person-years, 94.5 diabetes mellitus remissions were found in patients who underwent bariatric surgery compared with 4.9 diabetes mellitus remissions in matched control patients. Patients with diabetes who underwent bariatric surgery had an 18-fold increased chance for T2DM remission (adjusted relative rate [RR], 17.8; 95% CI, 11.2-28.4) compared with matched control patients. The greatest effect size was observed for gastric bypass (adjusted RR, 43.1; 95% CI, 19.7-94.5), followed by sleeve gastrectomy (adjusted RR, 16.6; 95% CI, 4.7-58.4) and gastric banding (adjusted RR, 6.9; 95% CI, 3.1-15.2). Body mass index and triglyceride, blood glucose, and hemoglobin A1c levels sharply decreased during the first 2 years after bariatric surgery. Population-based data show that bariatric surgery strongly increases the chance for remission of T2DM. Gastric bypass and sleeve gastrectomy have a greater effect than gastric banding. Although the risks and possible adverse effects of surgery should be weighed against its benefits, bariatric surgery and, in particular, gastric bypass or sleeve gastrectomy may be considered as new treatment options for T2DM.

Purpose: To report the first case of gold shunt surgery for treatment of silicone oil–induced refractory glaucoma in a tertiary care academic center, with 5-year follow-up. Design: The study design is a case report. Participants: The participant was a patient who underwent gold shunt surgery. Methods: Institutional Research Ethics Board approval for the study was obtained. A diabetic patient was referred for refractory glaucoma with a history of proliferative diabetic retinal detachment, and surgery with silicone oil. She was uncontrolled on maximal medical therapy and following informed consent, gold shunt surgery was performed. Ocular outcomes and number of medications were reviewed over a 5-year period. Results: Following uncomplicated surgery, intraocular pressure was reduced from 41 to 14 mm Hg, and the number of medications was reduced from 4 to 1. Glaucomatous optic neuropathy remained stable. Conclusions: Gold shunt surgery in this challenging case of silicone oil refractory glaucoma provided long-term intraocular pressure control and reduced need for medication over a 5-year period.

To determine whether simultaneous (ablation and reconstruction overlaps by two teams) head and neck reconstruction is cost effective compared to sequentially (ablation followed by reconstruction) performed surgery. Case-controlled study. Tertiary care hospital. Oncology patients undergoing free flap reconstruction of the head and neck. A match paired comparison study was performed with a retrospective chart review examining the total time of surgery for sequential and simultaneous surgery. Nine patients were selected for both the sequential and simultaneous groups. Sequential head and neck reconstruction patients were pair matched with patients who had undergone similar oncologic ablative or reconstructive procedures performed in a simultaneous fashion. A detailed cost analysis using the microcosting method was then undertaken looking at the direct costs of the surgeons, anesthesiologist, operating room, and nursing. On average, simultaneous surgery required 3 hours 15 minutes less operating time, leading to a cost savings of approximately $1200/case when compared to sequential surgery. This represents approximately a 15% reduction in the cost of the entire operation. Simultaneous head and neck reconstruction is more cost effective when compared to sequential 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 assess and compare the efficacy and safety of topical versus peribulbar anaesthesia in patients undergoing routine cataract surgery. The unicentre, prospective, randomized, clinical interventional trial included 140 consecutive patients undergoing routine cataract surgery performed by one of two surgeons. The patients were randomly distributed to either peribulbar anaesthesia or topical anaesthesia. To assess intraoperative pain, each patient was asked immediately after surgery to quantitate his/her pain using a 10-point pain rating scale. The study groups did not differ significantly in pain score (p=0.54), duration of surgery (p=0.52), anaesthesia-related intraoperative difficulties (p=0.17), postoperative visual acuity (p=0.94), overall intraoperative surgical complication rate, blood pressure rise (p=0.16) or blood oxygen saturation (p=0.74) Patient comfort and surgery-related complications did not differ between topical anaesthesia and peribulbar anaesthesia. As there are no significant differences between the two techniques in terms of subjective pain experienced by patients, intraoperative complications and postoperative visual outcome, and in view of the minimally invasive character of topical anaesthesia compared to peribulbar anaesthesia, the present study suggests the use of topical anaesthesia for routine cataract surgery.

Despite advancements in the creation and care of stomas, ostomy and peristomal skin complications are common immediately following surgery as well as in the months and years thereafter. A prospective study to determine the prevalence of ostomy and peristomal skin complications and the influence of ostomy configuration on such complications was conducted 1 year after ostomy surgery among all patients at a university hospital in Sweden. All participants received regular (10 to 14 days post discharge, 6 weeks, 3 months, 6 months, and 1 year post surgery) ostomy follow-up care by a wound ostomy continence (WOC) nurse. All consecutive elective and emergency patients who had undergone surgery to create a colostomy (end colostomy), end ileostomy, or loop ileostomy were eligible to participate. Patients who were reoperated during their first year post-surgery, patients with a urostomy, and patients with double ostomies were excluded from the study. Patient data collected included age, gender, diagnosis, elective or emergency surgery, open or laparoscopic surgical procedure, presence of a colorectal surgeon specialist at surgery, type of ostomy (colostomy, end ileostomy, loop ileostomy), preoperative ostomy siting, counseling, body mass index, American Society of Anesthesiologists classification, and radiation and/or chemotherapy status. Ostomies were evaluated by 4 WOC nurses as to stoma configuration, convexity use, patient self-sufficiency in stoma care, and complications. All 207 patients (53% women) who were eligible agreed to participate in the study. Patient median age was 70 years (range 19-94); 74% underwent elective surgery. Main diagnoses were colorectal cancer (62%) and inflammatory bowel disease (19%). Ostomy types were: colostomy (71%), end ileostomy (26%), and loop ileostomy (3%). One or more complications occurred in 35% of the patients (27% ostomy complications, 11% peristomal skin complications). A colostomy hernia was the most common surgical complication (20%), and significantly more women (69%) and emergency surgeries were noted among patients with a colostomy and an ostomy height of ≤5 mm. The use of convexity was significantly more common among patients with a stoma height of ≤5 mm than patients with stomas >5 mm (P = 0.016) and among patients having emergency operations than among patients having elective surgery (P = 0.045). Of the emergency surgeries, 37% had not been ostomy-sited (P <0.0001). With regular WOC nurse follow-up, the prevalence of peristomal skin complications in this population was low, and adequate ostomy height might have prevented the frequent use of convexity. Explorative studies are needed that consider differences in body configuration when determining optimal stoma height, especially for patients who require emergency surgery.

A multicenter, retrospective cohort study. To evaluate clinical outcomes in patients with reintubation after anterior cervical spine surgery. A total of 8887 patients undergoing anterior cervical spine surgery were enrolled in the AOSpine North America Rare Complications of Cervical Spine Surgery study. Patients with or without complications after surgery were included. Demographic and surgical information were collected for patients with reintubation. Patients were evaluated using a variety of assessment tools, including the modified Japanese Orthopedic Association scale, Nurick score, Neck Disability Index, and Short Form-36 Health Survey. Nine cases of postoperative reintubation were identified. The total prevalence of this complication was 0.10% and ranged from 0% to 0.59% across participating institutions. The time to development of airway symptoms after surgery was within 24 hours in 6 patients and between 5 and 7 days in 3 patients. Although 8 patients recovered, 1 patient died. At final follow-up, patients with reintubation did not exhibit significant and meaningful improvements in pain, functional status, or quality of life. Although the prevalence of reintubation was very low, this complication was associated with adverse clinical outcomes. Clinicians should identify their high-risk patients and carefully observe them for up to 2 weeks after surgery.

Inflammatory reactions are par- tially responsible for postoperative ileus (POI). Serum C-reactive protein (CRP) is an acknowledged marker of inflammation. In this study the CRP response with respect to POI in elective colorectal surgery was exam- ined to define the role of serum CRP as an early predic- tor of POI. Three hundred eighty-three patients who underwent elective colorectal resection were identified for inclusion in this study. We defined early POI as that occurring within 30 days following the surgery. Thirty-five patients with POI were com- pared to a subgroup of 348 patients with an unevent- ful postoperative course, and the correlation between postoperative serum CRP levels and POI in colorectal surgery was investigated. In the univariate analysis, length of operation, surgical blood loss, and serum CRP were factors significantly associated with POI following colorectal surgery; however, these fac- tors lost their significance on multivariate analysis. Our results suggest that an increase in CRP levels alone is not a predictor for POI following surgery for colorectal surgery. Although inflammatory responses are known to contribute to the ileus, ad- ditional study is required to identify risk factors that would be more useful for prediction of POI.

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.

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.

Driving a car is the most common form of transport among the older population. Common medical conditions such as cataract, increase with age and impact on the ability to drive. To compensate for visual decline, some cataract patients may self-regulate their driving while waiting for cataract surgery. However, little is known about the self-regulation practices of older drivers throughout the cataract surgery process. The aim of this study is to assess the impact of first and second eye cataract surgery on driver self-regulation practices, and to determine which objective measures of vision are associated with driver self-regulation. Fifty-five older drivers with bilateral cataract aged 55+ years were assessed using the self-reported Driving Habits Questionnaire, the Mini-Mental State Examination and three objective visual measures in the month before cataract surgery, at least one to three months after first eye cataract surgery and at least one month after second eye cataract surgery. Participants' natural driving behaviour in four driving situations was also examined for one week using an in-vehicle monitoring device. Two separate Generalised Estimating Equation logistic models were undertaken to assess the impact of first and second eye cataract surgery on driver-self-regulation status and which changes in visual measures were associated with driver self-regulation status. The odds of being a self-regulator in at least one driving situation significantly decreased by 70% after first eye cataract surgery (OR: 0.3, 95% CI: 0.1-0.7) and by 90% after second eye surgery (OR: 0.1, 95% CI: 0.1-0.4), compared to before first eye surgery. Improvement in contrast sensitivity after cataract surgery was significantly associated with decreased odds of self-regulation (OR: 0.02, 95% CI: 0.01-0.4). The findings provide a strong rationale for providing timely first and second eye cataract surgery for older drivers with bilateral cataract, in order to improve their mobility and independence.

Assess the incidence and determinants of hospitalization for deliberate self-harm and mental health disorders, and suicide after bariatric surgery. Limited recent literature suggests an increase in deliberate self-harm following bariatric surgery. A state-wide, population-based, self-matched, longitudinal cohort study over a 5-year period between 2007 and 2011. Utilizing the Western Australian Department of Health Data Linkage Unit records, all patients undergoing bariatric surgery (n = 12062) in Western Australia were followed for an average 30.4 months preoperatively and 40.6 months postoperatively. There were 110 patients (0.9%) hospitalized for deliberate self-harm, which was higher than the general population [incidence rate ratio (IRR) 1.47, 95% confidence interval (CI) 1.11-1.94, P = 0.005]. Compared with before surgery, there was no significant increase in deliberate self-harm hospitalizations (IRR 0.79, 95% CI 0.54-1.16; P = 0.206) and a reduction in overall mental illness related hospitalizations (IRR 0.76, 95% CI 0.63-0.91; P = 0.002) after surgery. Younger age, no private-health insurance cover, a history of hospitalizations due to depression before surgery, and gastrointestinal complications after surgery were predictors for deliberate self-harm hospitalizations after bariatric surgery. Three suicides occurred during the follow-up period, a rate comparable to the general population during the same time period (IRR 0.61, 95% CI 0.11-2.27, P = 0.444). Hospitalization for deliberate self-harm in bariatric patients was more common than the general population, but an increased incidence of deliberate self-harm after bariatric surgery was not observed. Hospitalization for depression before surgery and major postoperative gastrointestinal complications after bariatric surgery are potentially modifiable risk factors for deliberate self-harm after bariatric surgery.

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).

Surgery has played an essential role in the treatment of Crohn's disease. Emergency can reveal previously unknown complications whose treatment affects prognosis. Indicate the incidence of indications in emergent surgery for Crohn's disease. Specify the types of procedures performed in these cases and assess the Results of emergency surgery for Crohn's disease postoperatively,  in short , medium and long term. Retrospective analysis of collected data of 38 patients, who underwent surgical resection for Crohn's disease during a period of 19 years from 1992 to 2011 at the department of surgery in MONGI SLIM Hospital, and among them 17 patients underwent emergency surgery for Crohn's disease. In addition to socio-demographic characteristics and clinical presentations of our study population, we evaluated the indications, the type of intervention, duration of evolution preoperative and postoperative complications and overall prognosis of the disease. Of the 38 patients with Crohn's disease requiring surgical intervention, 17/38 patients underwent emergency surgery. Crohn's disease was inaugurated by the complications requiring emergency surgery in 11 patients. The mean duration of symptoms prior to surgery was 1.5 year. The most common indication for emergency surgery was acute intestinal obstruction (n=6) followed by perforation and peritonitis (n=5). A misdiagnosis of appendicitis was found in 4 patients and a complicated severe acute colitis for undiagnosed Crohn's disease was found in 2 cases. The open conventional surgery was performed for 15 patients. Ileocolic resection was the most used intervention. There was one perioperative mortality and 5 postoperative morbidities. The mean of postoperative hospital stay was 14 days (range 4-60 days). Six patients required a second operation during the follow-up period. The incidence of emergency surgery for Crohn's disease in our experience was high (17/38 patients), and is not as rare as the published estimates. Emergency surgical indication could be frequently the first presentation of Crohn's disease.  Acute intestinal obstruction and perforation-peritonitis were the most common indications for emergent surgery in Crohn's disease in our study.

Despite preoperative screening and treatment for urinary tract infections, a postoperative urinary tract infection develops in approximately 1 in 5 urogynecologic patients. In this study we assess the proportion of urogynecologic patients with a positive day of surgery urine culture, the clinical consequences of a positive day of surgery culture and differences in postoperative urinary tract infection risks based on day of surgery culture. After institutional review board approval, patients undergoing urogynecologic surgery at Loyola University Medical Center were recruited for the study. Catheterized urine samples were collected in the operating room before intravenous antibiotic administration. Clinical cultures were considered positive if 1,000 colonies per ml or more bacteria were found on routine culture. For analysis we matched each woman with a positive culture with 2 women with negative culture by age within 10 years and within surgical groups (ie prolapse and/or incontinence). Data were analyzed using SPSS® version 19. Nearly a tenth (9.5%) of participants had positive day of surgery cultures. The clinical and demographic characteristics were similar in women with negative vs positive day of surgery cultures. However, women with positive day of surgery cultures were more likely to experience a postoperative urinary tract infection despite standard perioperative antibiotic administration (29.6% vs 5.6%, p = 0.005, odds ratio 7.2). Regardless of day of surgery culture status no participant experienced postoperative systemic urinary complications. Nearly a tenth of urogynecologic patients had positive day of surgery cultures. Patients with a positive day of surgery culture had an increased risk (29.6%) of postoperative urinary tract infection within 6 weeks of surgery. These findings highlight an opportunity to identify and treat patients with positive day of surgery cultures and reduce the incidence of postoperative urinary tract infections.

2017-01-01

Surgical site infection (SSI) continues to be a challenge in colorectal surgery. Over the years, various modalities have been used in an attempt to reduce SSI risk in elective colorectal surgery, which include mechanical bowel preparation before surgery, oral antibiotics and intravenous antibiotic prophylaxis at induction of surgery. Even though IV antibiotics have become standard practice, there has been a debate on the exact role of oral antibiotics. The primary aim was to identify the role of oral antibiotics in reduction of SSI in elective colorectal surgery. The secondary aim was to explore any potential benefit in the use of mechanical bowel preparation (MBP) in relation to SSI in elective colorectal surgery. Medline, Embase and the Cochrane Library were searched. Any randomised controlled trials (RCTs) or cohort studies after 1980, which investigated the effectiveness of oral antibiotic prophylaxis and/or MBP in preventing SSIs in elective colorectal surgery were included. Twenty-three RCTs and eight cohorts were included. The results indicate a statistically significant advantage in preventing SSIs with the combined usage of oral and systemic antibiotic prophylaxis. Furthermore, our analysis of the cohort studies shows no benefits in the use of MBP in prevention of SSIs. The addition of oral antibiotics to systemic antibiotics could potentially reduce the risk of SSIs in elective colorectal surgery. Additionally, MBP does not seem to provide a clear benefit with regard to SSI prevention.

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.

SUMMARY A retroauricular approach is routinely used for treating chronic otitis media. The incidence of surgical site infections after ear surgery is around 10% in contaminated or dirty procedures. This observational prospective study describes surgical site infections after chronic otitis media surgery with the retroauricular approach and investigated their potential predictive factors. This observational prospective study included patients suffering from chronic otitis media and eligible for therapeutic surgery with a retroauricular approach. During follow-up, surgical site infections were defined as "early" if occurring within 30 days after surgery or as "late" if occurring thereafter. The data of 102 patients were analysed. Concerning early surgical site infections, four cases were diagnosed (3.9%) and a significant association was found with preoperative antibiotic therapy, wet ear at pre-operative examination, class III (contaminated) in the surgical wound classification, NNIS (National Nosocomial Infection Surveillance) index > 1, and oral post-operative antibiotic use. Seven late surgical site infections were diagnosed (7.1%) between 90 and 160 days after surgery and were significantly correlated to otorrhoea during the 6 months before surgery, surgery duration ≤60 minutes, canal wall down technique and use of fibrin glue. Surgical site infections after chronic otitis media surgery seem to be associated with factors related to the inflammatory state of the middle ear at the time of surgery in early infections and with chronic inflammation in late infections.

The Plastic Surgery In-Service Training Exam is a knowledge assessment tool widely used during plastic surgery training in the United States. This study analyzed literature supporting correct answer choices to determine highest yield sources, journal publication lag, and journal impact factors. Digital syllabi of 10 consecutive Plastic Surgery In-Service Training Exam administrations (2006 to 2015) were reviewed. The most-referenced articles, journals, and textbooks were determined. Mean journal impact factor and publication lag were calculated and differences were elucidated by section. Two thousand questions and 5386 references were analyzed. From 2006 to 2015, the percentage of journal citations increased, whereas textbook references decreased (p < 0.001). Plastic and Reconstructive Surgery was cited with greatest frequency (38.5 percent), followed by Clinics in Plastic Surgery (5.6 percent), Journal of Hand Surgery (American volume) (5.1 percent), and Annals of Plastic Surgery (3.8 percent). There was a trend toward less publication lag over the study period (p = 0.05), with a mean publication lag of 9.1 ± 9.0 years for all journal articles. Mean journal impact factor was 2.3 ± 4.3 and lowest for the hand and lower extremity section (1.7 ± 2.8; p < 0.001). The highest yield textbooks were elucidated by section. Plastic surgery faculty and residents may use these data to facilitate knowledge acquisition during residency.

Although significant late tricuspid regurgitation (TR) may develop after surgery for degenerative mitral regurgitation (MR), the use of routine tricuspid annuloplasty is debatable. The study aim was to determine the prevalence and predictors of significant late TR after surgery for degenerative MR. A total of 112 patients who had undergone surgery for degenerative MR without concomitant tricuspid valve repair (average follow up 7.7 ± 4.0 years) was studied retrospectively. The prevalence of post-surgical TR and predictors of progression were determined. The majority of patients (97%) had non-significant TR (less than moderate) prior to surgery, although an overall trend of progression towards significant TR (grades 2 or 3) was noted in 17 patients (p = 0.0006). Of the 18 patients (16%) with late postoperative significant TR, only nine (8%) had severe TR with only a single referral to surgery. New-onset post-surgical atrial fibrillation was more common in patients who developed late significant TR (p = 0.002). Multivariate analysis of the pre-surgery variables, age >65 years and left ventricular dysfunction were shown to be independent predictors of late functional TR. Significant progression in TR after surgery for degenerative MR was rare in this patient cohort. The impact of older age and left ventricular dysfunction at the time of surgery showed a strong association with post-surgical atrial fibrillation.

More than forty years after the first open heart surgery in Nigeria, all open heart surgeries were carried out in government-owned hospitals before the introduction of such surgeries in 2013 at Biket Medical Centre, a privately owned hospital in Osogbo, South-western Nigeria. The aim of this paper is to review our initial experience with open heart surgery in this private hospital. All patients who underwent open heart surgery between August 2013 and January 2014 were included in this prospective study. The medical records of the patients were examined and data on age, sex, diagnosis, type of surgery, cardiopulmonary bypass details, complications and length of hospital stay were extracted and the data was analysed using SPSS version 16. Eighteen patients comprising of 12 males and 6 females with ages ranging between 8 months and 52 years (mean= of 15.7 +/- 15 years) were studied. Pericardial patch closure of isolated ventricular septal defect was done in 7 patients (38.9%) while total correction of isolated tetralogy of Fallot was carried out in 5 patients (27.8%). Two patients had mitral valve repair for rheumatic mitral regurgitation. Sixty day mortality was 0%. Safe conduct of open heart surgery in the private hospital setting is feasible in Nigeria. It may be our only guarantee of hitch free and sustainable cardiac surgery.

Background: To determine and analyze the reasons why keratorefractive surgery, laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) were not performed in patients who presented for refractive surgery consultation. Materials and Methods: A retrospective observational study was performed between January 2006 and December 2007 in the Yemen Magrabi Hospital. The case records of 2,091 consecutive new patients who presented for refractive surgery were reviewed. Information from the pre-operative ophthalmic examination, such as refractive error, corneal topography and visual acuity, were analyzed. The reasons for not performing LASIK and PRK in the cases that were rejected were recorded and analyzed. Results: In this cohort, 1,660 (79.4%) patients were advised to have LASIK or PRK from the 2,091 patients examined. LASIK and PRK were not advised in 431 (21%) patients. The most common reasons for not performing the surgery were high myopia >-11.00 Diopters (19%), keratoconus (18%), suboptimal central corneal thickness (15%), cataract (12%) and keratoconus suspect (forme fruste keratoconus) (10%). Conclusion: Patients who requested keratorefractive surgery have a variety of problems and warrant comprehensive attention to selection criteria on the part of the surgeon. Corneal topographies and pachymetry of refractive surgery candidates need to be read cautiously. High-refractive error, keratoconus and insufficient corneal thickness were found to be the leading reasons for not performing keratorefractive surgery in this study. PMID:21180437

Patient characteristics and surgery-related factors associated with patient-reported recovery at 1 and 6 months after colorectal cancer surgery.

Predictors for postoperative recovery after colorectal cancer surgery are usually investigated in relation to length of stay (LoS), readmission, or 30-day morbidity. This study describes patient characteristics and surgery-related factors associated with patient-reported recovery 1 and 6 months after surgery. In total, 153 consecutively included patients who were recovering from colorectal cancer surgery reported their level of recovery using the Postoperative Recovery Profile. Multiple logistic regression analysis was used to calculate associations with recovery, defined as good or poor, divided into five recovery dimensions: physical symptoms, physical functions, psychological, social and activity. Better preoperative health predicted good recovery regarding three dimensions 1 month after surgery. Regarding all dimensions 1 month after surgery, poor recovery was predicted by a poor recovery on the day of discharge within corresponding dimensions. Higher age was associated with good recovery 6 months after surgery, while chemotherapy showed negative associations. Overall, a majority of factors had a negative impact on recovery, but without any obvious relation to one specific dimension or point in time. Those factors were: high Body Mass Index, comorbidity, abdominoperineal resection, loop ileostomy, colostomy and LoS. This study illustrates the complexity of postoperative recovery and a need for individualised follow-up strategies. © 2017 John Wiley & Sons Ltd.

(Extreme) obesity is a chronic harmful condition with high risk of medical comorbidities and negative social and emotional consequences. Bariatric surgery is an effective intervention for obesity, but approximately 20 to 30% of the patients experience adverse outcomes after surgery and there is a need for augmentation of current treatment strategies. This study examines the added value of pre-operative cognitive behavioral therapy (CBT) focused on modification of thoughts and behaviors in terms of eating behavior and physical exercise as well as preparation for surgery and postoperative life style. We hypothesize that pre-operative CBT will result in better weight loss maintenance, reduction of maladaptive eating behavior and better adherence to postoperative lifestyle on the long term as compared to bariatric surgery alone. One hundred and twenty eight patients that are on a waiting list for bariatric surgery are randomly assigned to the control or treatment condition. Patients in the treatment condition receive 10 sessions of CBT before surgery aimed at modifying dysfunctional eating habits and behaviors and developing more rational weight and body-related beliefs in order to enable long term maintenance of a healthier lifestyle after surgery. Weight loss, eating behavior, eating disorders, depression, quality of life and psychological distress are assessed before and after treatment, as well as 1, 3, and 5 year following surgery.

Minimally invasive colorectal surgery: status and technical specifications.

Keller, D S; Ibarra, S; Haas, E M

2015-10-01

Laparoscopy was the most significant technologic advance in colorectal surgery in the last quarter century. The safety, feasibility and oncologic equivalence have been proven, and undisputed clinical benefits have also been demonstrated over open approaches. Despite proven benefits, laparoscopic has not dominated the market, especially for colon and rectal cancer cases. Adaptations in laparoscopic technique were developed to increase use of minimally invasive surgery. Concurrently, there has been a paradigm shift toward less invasive technologies to further optimize patient outcomes. From these needs, hand assisted laparoscopic surgery (HALS), single incision laparoscopic surgery (SILS), and robotic assisted laparoscopic surgery (RALS) were applied to colorectal surgery. Each platform has unique costs and benefits, and similar outcomes when likened to each other in comparative studies. However, conventional laparoscopy, HALS, SILS, and RALS actually serve a complementary role as tools to increase the use of minimally invasive colorectal surgery. The goal of this paper is to review the history, current status, technical specifications, and evolution of the major minimally invasive platforms for colorectal surgery.

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.

To review some current controversies in hair transplant surgery. Review of the English PubMed literature and specialty literature in hair transplant surgery. Some of the controversies in hair transplant surgery include appropriate donor harvesting technique including elliptical donor harvesting versus follicular unit extraction whether manual versus robotic, the role of platelet-rich plasma and low-level light surgery in hair transplant surgery. Hair transplant surgery creates consistently natural appearing hair. As with all techniques, there are controversies regarding the optimal method for performing the procedure. Some of the current controversies in hair transplant surgery include optimal donor harvesting techniques, elliptical donor harvesting versus follicular unit extraction, the role of low-level light therapy and the platelet-rich plasma therapy in the procedure. Future studies will further clarify their role in the procedure.

Public awareness and concern about cosmetic surgery on children is increasing. Nationally and internationally questions have been raised by the media and government bodies about the appropriateness of children undergoing cosmetic surgery. Considering the rates of cosmetic surgery in comparable Western societies, it seems likely that the number of physicians in Australia who will deal with a request for cosmetic surgery for a child will continue to increase. This is a sensitive issue and it is essential that physicians understand the professional and legal obligations that arise when cosmetic surgery is proposed for a child. This article reviews the current professional and legal obligations that physicians have to competent and incompetent children for whom cosmetic surgery has been requested. A case study is used to highlight the factors that Australian primary care physicians must consider before referring and conducting cosmetic surgery on children.

Surgical and healing changes to ocular aberrations following refractive surgery

Purpose: To measure ocular aberrations before and at several time periods after LASIK surgery to determine the change to the aberration structure of the eye. Methods: A Shack-Hartmann wavefront sensor was used to measure 88 LASIK patients pre-operatively and at 1 week and 12 months following surgery. Reconstructed wavefront errors are compared to look at induced differences. Manifest refraction was measured at 1 week, 1 month, 3 months, 6 months and 12 months following surgery. Sphere, cylinder, spherical aberration, and pupil diameter are analyzed. Results: A dramatic elevation in spherical aberration is seen following surgery. This elevation appears almost immediately and remains for the duration of the study. A temporary increase in pupil size is seen following surgery. Conclusions: LASIK surgery dramatically reduces defocus and astigmatism in the eye, but simultaneously increases spherical aberration levels. This increase occurs at the time of surgery and is not an effect of the healing response.

The development of imaging modalities and computer technology provides a new approach in acetabular surgery. Areas covered: This review describes the role of computer-assisted surgery (CAS) in understanding of the fracture patterns, in the virtual preoperative planning of the surgery and in the use of custom-made plates in acetabular fractures with or without 3D printing technologies. A Pubmed internet research of the English literature of the last 20 years was carried out about studies concerning computer-assisted surgery in acetabular fractures. The several steps for CAS in acetabular fracture surgery are presented and commented by the main author regarding to his personal experience. Expert commentary: Computer-assisted surgery in acetabular fractures is still initial experiences with promising results. Patient-specific biomechanical models considering soft tissues should be developed to allow a more realistic planning.

To investigate the effect of laser refractive surgery on night weapons firing. Firing range performance was measured at baseline and postoperatively following photorefractive keratectomy and laser in situ keratomileusis. Subjects fired the M-16A2 rifle with night vision goggles (NVG) at starlight, and with iron sight (simulated dusk). Scores, before and after surgery, were compared for both conditions. No subject was able to acquire the target using iron sight without correction before surgery. After surgery, the scores without correction (95.9 +/- 4.7) matched the preoperative scores with correction (94.3 +/- 4.0; p = 0.324). Uncorrected NVG scores after surgery (96.4 +/- 3.1) exceeded the corrected scores before surgery (91.4 +/- 10.2), but this trend was not statistically significant (p = 0.063). Night weapon firing with both the iron sight and the NVG sight improved after surgery. This study supports the operational benefits of refractive surgery in the military.

Vocal cord palsy (VCP) is a known complication of anterior cervical spine surgery. However, the true incidence and interventions to minimize this complication are not well studied. To conduct a systematic review to identify the incidence, risk, and interventions for VCP after anterior cervical spine surgery. This is a qualitative systematic literature review. Prospective and retrospective trials of patients undergoing anterior cervical spine surgery that reported on postoperative VCP or recurrent laryngeal nerve palsy. Primary: incidence of VCP after anterior cervical spine surgery; secondary: risk factors and interventions for prevention of VCP after anterior cervical spine surgery. Electronic searches were conducted on Ovid Medline, EMBASE, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systemic Reviews for clinical studies reporting VCP in anterior cervical spine surgery, limited to studies published between 1995 and June 2013 in English and French languages. After selection of studies independently by two review authors, data on incidence, risk, and interventions were extracted. Qualitative analysis was performed on three domains: quality of studies, strength of evidence, and impact of interventions. Our search has identified 187 abstracts, and 34 studies met our inclusion criteria. The incidence of VCP ranges from 2.3% to 24.2%. Significant heterogeneity in study design and definition of VCP were used in the published studies. There is good evidence that reoperation increases the risk of VCP. One study of moderate strength suggests that operating from the right side may increase the risk of VCP. Among the interventions studied, endotracheal tube (ETT) cuff pressure monitoring with deflation during retraction has shown to reduce the incidence from 6% to 2%, but this result was not confirmed by randomized control trials. Limited evidence exists for other interventions of intraoperative electromyographic monitoring and methylprednisolone. Vocal cord palsy is a significant morbidity after anterior cervical surgery with incidence up to 24.2% in the immediate postoperative period, with a higher risk in reoperation of the anterior cervical spine. Moderate evidence exists for ETT cuff pressure adjustment in preventing this complication. Copyright © 2014 Elsevier Inc. All rights reserved.

Background: Recent reports have highlighted the progressive increase in the incidence of ulnar collateral ligament (UCL) injuries to the elbow in baseball players of all levels. However, knowledge of the incidence and other epidemiological factors regarding UCL injuries, specifically in college baseball players, is currently lacking. Purpose: To evaluate, over a period of 1 year, the incidence of UCL injuries requiring surgery in National Collegiate Athletic Association (NCAA) Division I baseball programs. Study Design: Descriptive epidemiology study. Methods: A total of 155 Division I collegiate baseball programs agreed to participate in the study. Demographics (position, year, background [location of high school]) for all players on these rosters were obtained from public websites. At the conclusion of the 2017 collegiate baseball season, the athletic trainer for each program entered anonymous, detailed information on injured players through an electronic survey into a secured database. Results: All 155 teams enrolled in the study completed the electronic survey. Of the 5295 collegiate baseball players on these rosters, 134 underwent surgery for an injured UCL (2.5% of all eligible athletes), resulting in a team surgery rate of 0.86 per program for 1 year. These 134 players came from 88 teams, thus 56.8% of the study teams underwent at least 1 surgery during the year. The surgery rate was 2.5 per 100 player-seasons for all players and was significantly higher among pitchers (4.4/100 player-seasons) than nonpitchers (0.7/100 player-seasons). The surgery rate was also significantly higher in underclassmen (3.1/100 player-seasons among freshmen and sophomores) than upperclassmen (1.9/100 player-seasons among juniors and seniors) (incidence rate ratio, 1.7; 95% CI, 1.1-2.4). Players from traditionally warm-weather states did not undergo UCL surgery at a significantly different rate from players from traditionally cold-weather states (2.7/100 player-seasons vs 2.1/100 player-seasons, respectively). Nearly half of surgeries (48.5%) were performed during the baseball season. Conclusion: The incidence of UCL surgeries in NCAA Division I collegiate baseball players represents substantial morbidity to this young athletic population. Risk factors for injuries requiring surgery include being a pitcher and an underclassman. Awareness of these factors should be considered in injury prevention programs. Furthermore, this initial study can serve as a foundation for tracking these surgical injuries in future years and then identifying trends over time. PMID:29687011

Predictive modeling of complications.

Predictive analytic algorithms are designed to identify patterns in the data that allow for accurate predictions without the need for a hypothesis. Therefore, predictive modeling can provide detailed and patient-specific information that can be readily applied when discussing the risks of surgery with a patient. There are few studies using predictive modeling techniques in the adult spine surgery literature. These types of studies represent the beginning of the use of predictive analytics in spine surgery outcomes. We will discuss the advancements in the field of spine surgery with respect to predictive analytics, the controversies surrounding the technique, and the future directions.

A comparative direct cost analysis of pediatric urologic robot-assisted laparoscopic surgery versus open surgery: could robot-assisted surgery be less expensive?

2012-07-01

Cost in healthcare is an increasing and justifiable concern that impacts decisions about the introduction of new devices such as the da Vinci(®) surgical robot. Because equipment expenses represent only a portion of overall medical costs, we set out to make more specific cost comparisons between open and robot-assisted laparoscopic surgery. We performed a retrospective, observational, matched cohort study of 146 pediatric patients undergoing either open or robot-assisted laparoscopic urologic surgery from October 2004 to September 2009 at a single institution. Patients were matched based on surgery type, age, and fiscal year. Direct internal costs from the institution were used to compare the two surgery types across several procedures. Robot-assisted surgery direct costs were 11.9% (P=0.03) lower than open surgery. This cost difference was primarily because of the difference in hospital length of stay between patients undergoing open vs robot-assisted surgery (3.8 vs 1.6 days, P<0.001). Maintenance fees and equipment expenses were the primary contributors to robotic surgery costs, while open surgery costs were affected most by room and board expenses. When estimates of the indirect costs of robot purchase and maintenance were included, open surgery had a lower total cost. There were no differences in follow-up times or complication rates. Direct costs for robot-assisted surgery were significantly lower than equivalent open surgery. Factors reducing robot-assisted surgery costs included: A consistent and trained robotic surgery team, an extensive history of performing urologic robotic surgery, selection of patients for robotic surgery who otherwise would have had longer hospital stays after open surgery, and selection of procedures without a laparoscopic alternative. The high indirect costs of robot purchase and maintenance remain major factors, but could be overcome by high surgical volume and reduced prices as competitors enter the market.

The advancement of surgical technology has made surgery an increasingly suitable management option for an increasing number of medical conditions. Yet there is also a growing concern about the number of patients coming to harm as a result of surgery. Studies show that this harm can be prevented by better teamwork and communication in operating theatres. This article discusses the extent of adverse events in surgery and how effective teamwork and communication can improve patient safety. It also highlights the role checklists and briefing in improving teamwork and reducing human error in surgery.

2008-01-01

Robotic surgery is being used with increasing frequency in gynecologic oncology. To date, 44 cases were reported in the literature of radical hysterectomy performed with robotic surgery. When comparing robotic surgery with laparoscopy or laparotomy in performing a radical hysterectomy, the literature shows that robotic surgery offers an advantage over the other 2 surgical approaches with regard to operative time, blood loss, and length of hospitalization. Future studies are needed to further elucidate the equivalence or superiority of robotic surgery to laparoscopy or laparotomy in performing a radical hysterectomy.

In Canada, there has been a disproportionate increase in adults with Class II (BMI 35.0-39.9 kg/m 2 ) or Class III obesity (BMI ≥ 40 kg/m 2 ) affecting 9 % of Canadians with increases projected. Individuals affected by severe obesity (BMI ≥ 35) are at increased risk of high blood pressure, cardiovascular disease, diabetes, cancer, impaired quality of life, and premature mortality. Bariatric surgery is the most effective treatment for severe obesity. Laparoscopic sleeve gastrectomy (LSG), a relatively new type of bariatric surgery, is growing in popularity as a treatment. The global prevalence of LSG increased from 0 to 37.0 % between 2003 and 2013. In Canada and the US, between 2011 and 2013, the number of LSG surgeries increased by 244 % and LSG now comprises 43 % of all bariatric surgeries. Since 2011, Eastern Health, the largest regional health authority in Newfoundland and Labrador (NL), Canada has performed approximately 100 LSG surgeries annually. A population-based prospective cohort study with pre and post surgical assessments at 1, 3, 6, 12, 18, 24 months and annually thereafter of patients undergoing LSG. This study will report on short - to mid-term (2-4 years) outcomes. Patients (n = 200) followed by the Provincial Bariatric Surgery Program between 19 and 70 years of age, with a BMI between 35.0 and 39.9 kg/m 2 and an obesity-related comorbidity or with a BMI ≥ 40 kg/m 2 are enrolled. The study is assessing the following outcomes: 1) complications of surgery including impact on nutritional status 2) weight loss/regain 3) improvement/resolution of comorbid conditions and a reduction in prescribed medications 4) patient reported outcomes using validated quality of life tools, and 5) impact of surgery on health services use and costs. We hypothesize a low complication rate, a marked reduction in weight, improvement/resolution of comorbid conditions, a reduction in related medications, improvement in quality of life, and a decrease in direct healthcare use and costs and indirect costs compared to pre-surgery. Limited data on the impact of LSG as a stand-alone procedure on a number of outcomes exist. The findings from this study will help to inform evidence-based practice, clinical decision-making, and the development of health policy.

Objectives To address the value of surgery in sporadic Zollinger-Ellison syndrome (ZES) patients with negative imaging studies. Background Medical control of acid hypersecretion in patients with sporadic Zollinger-Ellison syndrome (ZES) is highly effective. This has led to these patients frequently not sent to surgery, especially if preoperative imaging studies are negative, due in large part because almost no data exists on the success of surgery in this group. Methods 58 prospectively studied sporadic ZES patients (17% of total studied) had negative imaging studies and their surgical outcome was compared to 117 patients with positive imaging results. Results 35 patients had negative imaging in the pre-somatostatin receptor scintigraphy era (SRS) and 23 in the post-SRS era. The image negative patients had long disease histories prior to surgery (mean±SEM, from onset=7.9±1[range −0.25-35 yrs]) and 25% were followed ≥2yrs from diagnosis. At surgery, gastrinoma was found in 57/58 patients (98%). Tumors were small (mean=0.8cm, 60% < 1 cm). The most common primary sites were: duodenal 64%, pancreatic 17%, and lymph node (LN)(10%). 50% had a primary only, 41% primary + LN, and 7% had liver metastases. 35/58(60%) were cured immediately postoperatively and at last follow-up [mean-9.4yrs, range 0.2-22yrs], 27 patients (46%) remained cured. During follow-up 3 patients died, each was found to have liver metastases at surgery. In comparison to the image positive patients, those with negative imaging had lower preop fasting gastrin levels; a longer delay prior to surgery; more frequently had a small duodenal tumors; less frequently had a pancreatic tumor, multiple tumors or developed a new lesion postoperatively and had a longer survival. Conclusions Imaging negative sporadic ZES patients are not rare even in the post-SRS period. An experienced surgeon can find gastrinoma in almost every patient (98%) and nearly one-half (46%) are cured, a rate similar to imaging positive tumor patients. Because liver metastases were found in 7%, which may have been caused by a long delay in surgery and all the disease-related deaths occurred in this group, surgery should be routinely undertaken early in ZES patients despite negative imaging studies.

Operative experience in aesthetic surgery is an important issue affecting plastic surgery residents. This study addresses the variability of aesthetic surgery experience during plastic surgery residency. National operative case logs of chief residents in independent/combined and integrated plastic surgery residency programs were analyzed (2011-2015). Fold differences between the bottom and top 10th percentiles of residents were calculated for each aesthetic procedure category and training model. The number of residents not achieving case minimums was also calculated. Case logs of 818 plastic surgery residents were analyzed. There was marked variability in craniofacial (range, 6.0-15.0), breast (range, 2.4-5.9), trunk/extremity (range, 3.0-16.0), and miscellaneous (range, 2.7-22.0) procedure categories. In 2015, the bottom 10th percentile of integrated and independent/combined residents did not achieve case minimums for botulinum toxin and dermal fillers. Case minimums were achieved for the other aesthetic procedure categories for all graduating years. Significant variability persists for many aesthetic procedure categories during plastic surgery residency training. Greater efforts may be needed to improve the aesthetic surgery experience of plastic surgery residents. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

2016-10-01

Bariatric surgery, initially intended as a weight-loss procedure, is superior to standard lifestyle intervention and pharmacological therapy for type 2 diabetes in obese individuals. Intensive medical management of hyperglycemia is associated with improved microvascular outcomes. Whether or not the reduction in hyperglycemia observed after bariatric surgery translates to improved microvascular outcomes is yet to be determined. There is substantial heterogeneity in the data relating to the impact of bariatric surgery on diabetic retinopathy (DR), the most common microvascular complication of diabetes. This review aims to collate the recent data on retinal outcomes after bariatric surgery. This comprehensive evaluation revealed that the majority of DR cases remain stable after surgery. However, risk of progression of pre-existing DR and the development of new DR is not eliminated by surgery. Instances of regression of DR are also noted. Potential risk factors for deterioration include severity of DR at the time of surgery and the magnitude of glycated hemoglobin reduction. Concerns also exist over the detrimental effects of postprandial hypoglycemia after surgery. In vivo studies evaluating the chronology of DR development and the impact of bariatric surgery could provide clarity on the situation. For now, however, the effect of bariatric surgery on DR remains inconclusive.

Vascular surgery fellowship training has evolved with the widespread adoption of endovascular interventions. The purpose of this study is to examine how general surgery trainee exposure to vascular surgery has changed over time. Review of the Accreditation Council for Graduate Medical Education national case log reports for graduating Vascular Surgery Fellows (VF), and general surgery residents (GSR) from 2001 to 2012 was performed. The number of GSR increased from 1021 to 1098, and the number of VF increased from 96 to 121 from 2001 to 2012. The total number of vascular cases done by VF increased by 1161 since 2001 (298-762), whereas the total number of vascular cases done by GSR has decreased by 40% during this time period (186-116). Vascular fellows increase was due primarily to an increase in endovascular experience; a finding not noted in general surgery residents. Vascular fellow case log changes are due primarily to an increase in endovascular experience that has not been mirrored by general surgery trainees. Open surgery experience has decreased overall for general surgery residents in all major categories, a change not seen in vascular surgery fellows. Copyright © 2016 Elsevier Inc.

Surgical treatment of elderly patients with meningioma is has proved to be safe, especially when patients are selected using dedicated surgical scores. These scores take into account tumor size, edema, location and patient's co-morbidities. Neuropsychological functioning (NPF) of this kind of patients has been poorly studied in literature and it is not taken into account by these scores. Aim of our study was to describe the long-term outcome in terms of NPF of elderly patients undergoing surgery. Patients older than 70 years of age affected by intracranial meningioma and selected with the Clinical-Radiological Grading Score were included in our study. Neuropsychological testing was performed using a dedicated battery of tests before surgery, 3 and 12 months after surgery. Clinical, neurological and radiological outcomes were studied as well. Forty-one patients with a median age of 74 years were included in this study. Preoperatively only 1/41 patients showed a normal NPF with all tests scoring normally. Four out of 39 patients showed a complete neuropsychological recovery after 3 months; while 10/37 patients had a complete recovery after 12 months. NPF showed a trend of progressive improvement after surgery. Our study is the first experience reported in literature describing a long term follow-up in elderly patients after surgery for intracranial meningioma. In our series, surgery determined an improvement of NPF over time; especially with a low complication rate related to the selection of patients obtained through the CRGS. Further studies need to be performed in order to understand how brain edema, tumor size, volume and tumor location affect NPF in both short and long term.

Despite a growing interest in examining the effects of industry funding on research in plastic surgery, no study to date has comprehensively examined the effects of financial conflicts of interest on publication outcomes. The authors investigated the association between financial conflicts of interest and reported study findings in plastic surgery research. The authors reviewed all entries in Plastic and Reconstructive Surgery, Annals of Plastic Surgery, and Journal of Plastic, Reconstructive & Aesthetic Surgery from January 1, 2012, to December 31, 2012. All clinical and basic science articles were analyzed. The following article characteristics were extracted: self-reported financial conflicts of interest, sample size, level of evidence, study design, and prospectiveness. The findings reported in each abstract were blindly graded as not applicable, negative, or positive. Of the 1650 abstracts that resulted from the authors' initial search, 568 fulfilled the inclusion criteria. The majority of the included articles covered breast (20.8 percent), experimental (19.7 percent), and general reconstruction (31.69 percent). Financial conflicts of interest were disclosed in only 17.6 percent of the articles. Of the total studies that met inclusion criteria, 66.2 percent were reviewed as having positive outcomes, and 33.8 percent were reviewed as having negative or not applicable results. Studies that disclosed a financial conflict of interest were 7.12 times more likely (p < 0.0001) to present a positive outcome over a negative outcome compared with studies with no financial conflict of interest. Investigators with a financial conflict of interest are significantly more likely to publish plastic surgery studies with a positive conclusion compared with investigators with no conflicts of interest.

Robotic-Assisted Procedures in Pediatric Surgery: A Critical Appraisal of the Current Best Evidence in Comparison to Conventional Minimally Invasive Surgery.

PubMed

Friedmacher, Florian; Till, Holger

2015-11-01

In recent years, the use of robotic-assisted surgery (RAS) has expanded within pediatric surgery. Although increasing numbers of pediatric RAS case-series have been published, the level of evidence remains unclear, with authors mainly focusing on the comparison with open surgery rather than the corresponding laparoscopic approach. The aim of this study was to critically appraise the published literature comparing pediatric RAS with conventional minimally invasive surgery (MIS) in order to evaluate the current best level of evidence. A systematic literature-based search for studies comparing pediatric RAS with corresponding MIS procedures was performed using multiple electronic databases and sources. The level of evidence was determined using the Oxford Centre for Evidence-based Medicine (OCEBM) criteria. A total of 20 studies met defined inclusion criteria, reporting on five different procedures: fundoplication (n=8), pyeloplasty (n=8), nephrectomy (n=2), gastric banding (n=1), and sleeve gastrectomy (n=1). Included publications comprised 5 systematic reviews and 15 cohort/case-control studies (OCEBM Level 3 and 4, respectively). No studies of OCEBM Level 1 or 2 were identified. Limited evidence indicated reduced operative time (pyeloplasty) and shorter hospital stay (fundoplication) for pediatric RAS, whereas disadvantages were longer operative time (fundoplication, nephrectomy, gastric banding, and sleeve gastrectomy) and higher total costs (fundoplication and sleeve gastrectomy). There were no differences reported for complications, success rates, or short-term outcomes between pediatric RAS and conventional MIS in these procedures. Inconsistency was found in study design and follow-up with large clinical heterogeneity. The best available evidence for pediatric RAS is currently OCEBM Level 3, relating only to fundoplication and pyeloplasty. Therefore, higher-quality studies and comparative data for other RAS procedures in pediatric surgery are required.

The Effect of Metabolic and Bariatric Surgery on DNA Methylation Patterns.

2017-08-30

Metabolic and bariatric surgery (MBS) is considered to be the most effective treatment for obesity. Not only due to the significant weight reduction but also because of the many health benefits associated with it. In the last 5 years, several studies have suggested that epigenetic modifications could be involved in the mechanisms underlying the response to bariatric surgery. In this review, we will compile the different studies (2012-2017) concerning the effect of this surgical procedure on DNA methylation patterns (the most studied epigenetic marker) and its association with metabolic improvement. This is an emerging area, and currently, there are not many studies in the literature. The aim is to show what has been done so far and what the future direction in this emerging area might be. Recent findings have shown how metabolic and bariatric surgery modifies the DNA methylation profile of the specific genes associated with the pathophysiology of the disease. The studies were performed in morbidly obese subjects, mainly in women, with the aim of reducing weight and improving the obesity-associated comorbidities. DNA methylation has been measured both in specific tissue and in peripheral blood samples. In general, studies about site-specific DNA methylation have shown a change in the methylation profile after surgery, whereas the studies analyzing global DNA methylation are not so conclusive. Summing up, metabolic and bariatric surgery can modify the DNA methylation profile of different genes and contributes to the metabolic health benefits that are often seen after metabolic and bariatric surgery. Although there are still many issues to be resolved, the capacity to revert the DNA methylation profile of specific sites opens a window for searching for target markers to treat obesity-related comorbidities.

Objective: To evaluate the safety and effectiveness of robotic surgery in surgical staging of endometrial cancer. Methods: Searched English and Chinese databases, including Cochrane library, PubMed, Embase, Web of Science, China National Knowledge Internet, data base of Wanfang, China Science and Technology Journal (CSTJ) , and relevant journals and magazines by hand from Jan. 2000 to Oct. 2016. (1) In accordance with the inclusion criteria, two independent investigators screened databases and extracted the relevant data respectively, then evaluated the quality of including studies in Newcastle-Ottawa Scale (NOS) . (2) Meta-analysis was performed with RevMan 5.3 software. Heterogeneity inspection was done for each study and different effect model included the random effect model and fixed effect model was chose according to the results: of the inspection. At last, the related parameters of the robotic surgery and laparoscopic surgery was analysed. Results (1) Thirteen articles were ultimately included. All of them were written in English and included a total of 1 554 patients, included 739 cases of robotic surgery and 815 cases of laparoscopic surgery. Thirteen articles were all cohort study, four of them were prospective cohort study, while others were retrospective cohort study. After quality assessment, all studies had more than 5 stars and illustrated the higher quality. (2) Meta-analysis results showed: compared with laparoscopic surgery in surgical staging of endometrial cancer, robotic surgery had less estimated blood loss [standard deviation ( SD )=-72.31 ml, 95% CI :-107.29 to-37.33, P <0.01], less time for hospital stay ( SD =-0.29 days, 95% CI :-0.46 to-0.13, P =0.001), less need for blood transfusion [risk ratio ( RR )=0.57, 95% CI : 0.33 to 0.97, P =0.040], and conversion to open surgery ( RR =0.41, 95% CI : 0.26 to 0.65, P =0.000), less intraoperative complications ( RR =0.43, 95% CI : 0.24 to 0.76, P =0.004) in surgical staging of endometrial cancer. There was no statistically significant difference in aspects of operative time ( SD =10.26 minutes, 95% CI :-13.62 to 34.13, P =0.400), postoperative complications ( RR =0.87, 95% CI : 0.67 to 1.12, P =0.280), the total number of lymph nodes removed ( SD =-0.04, 95% CI :-3.99 to 3.91, P =0.980), the number of pelvic lymph node dissection ( SD =0.48, 95% CI :-1.76 to 2.71, P =0.680) and the number of para-aortic lymph node dissection ( SD =0.46, 95% CI :-1.42 to 2.34, P =0.630). Conclusions: Compared the robotic surgery with laparoscopic surgery in surgical staging of endometrial cancer, robotic surgery has less estimated blood loss, less need for blood transfusion and conversion to open surgery, less intraoperative complications and other advantages. While its cost is so expensive that restrict clinical application.

This article describes the rationale and design of the DECREASE-XIII trial, which aims to evaluate the potential of esmolol infusion, an ultra-short-acting beta-blocker, during surgery as an add-on to chronic low-dose beta-blocker therapy to maintain perioperative haemodynamic stability during major vascular surgery. A double-blind, placebo-controlled, randomised trial. A total of 260 vascular surgery patients will be randomised to esmolol or placebo as an add-on to standard medical care, including chronic low-dose beta-blockers. Esmolol is titrated to maintain a heart rate within a target window of 60-80 beats per minute for 24 h from the induction of anaesthesia. Heart rate and ischaemia are assessed by continuous 12-lead electrocardiographic monitoring for 72 h, starting 1 day prior to surgery. The primary outcome measure is duration of heart rate outside the target window during infusion of the study drug. Secondary outcome measures will be the efficacy parameters of occurrence of cardiac ischaemia, troponin T release, myocardial infarction and cardiac death within 30 days after surgery and safety parameters such as the occurrence of stroke and hypotension. This study will provide data on the efficacy of esmolol titration in chronic beta-blocker users for tight heart-rate control and reduction of ischaemia in patients undergoing vascular surgery as well as data on safety parameters.

Objective Sternal bleeding during cardiac surgery is currently controlled using bone wax or other chemical substances that may result in adverse effects and affect wound healing and recovery. The purpose of this study was to identify a safe, cost-effective, and easy-to-use technique to reduce sternal bleeding and sternal trauma during cardiac surgery. Methods After sternotomy, a sternal protection device was placed over each hemisternal section before insertion of the retractor and remained in situ until the end of surgery. Sternal bleeding and ease of use were assessed and recorded during surgery. Sternal trauma was assessed and recorded within 5 minutes of removal of the device, and overall satisfaction (Global Impression) and any intraoperative adverse events or device malfunction were reported at surgery completion. Patients were followed up 24 hours and 4 weeks after surgery. Results Twelve patients completed the study. Adverse events reported were not considered related to the device. No sternal trauma was identified in any patient. In 9 of 11 patients, sternal bleeding was reduced after insertion of the device. The device was generally considered easy to use, although some difficulty was encountered when used with the Internal Mammary Artery retractor. Conclusions Our data suggest that the device is safe and able to reduce sternal bleeding during surgery using sternal retractors. We recommend further studies in a larger population of patients with a control group to evaluate the device's ability to reduce the morbidity associated with sternal bleeding and sternal trauma.

Guidelines recommend that patients with gastro-oesophageal reflux disease are adequately treated with acid-suppressive therapy before undergoing anti-reflux surgery. Little is known of the use of acid-suppressive drugs before anti-reflux surgery. To determine the use of proton pump inhibitors and H2 -receptor antagonists in the year before anti-reflux surgery. A nationwide retrospective study of all patients aged ≥18 undergoing first-time anti-reflux surgery in Denmark during 2000-2012 using data from three different sources: the Danish National Register of Patients, the Danish National Prescription Register, and the Danish Person Register. The study population thus included 2922 patients (median age: 48 years, 55.7% male). The annual proportion of patients redeeming ≥180 DDD of acid-suppressive therapy increased from 17.0% 5 years before anti-reflux surgery to 64.9% 1 year before. The probability for inadequate dosing 1 year before surgery (<180 DDD) was significantly increased for younger patients, patients operated in the period 2000-2003, patients who had not undergone pre-surgical manometry, pH- or impedance monitoring, and patients who had not redeemed prescriptions on NSAID or anti-platelet drugs. Compliance with medical therapy should be evaluated thoroughly before planning anti-reflux surgery, as a high proportion of patients receive inadequate dosing of acid-suppressive therapy prior to the operation. © 2015 John Wiley & Sons Ltd.

The late postoperative complications of choledochal cyst (CC) surgery are serious and include intrahepatic stones and biliary carcinoma; therefore, long-term follow-up is crucial. The subjects of this retrospective study were patients who underwent surgery for CC at Kagoshima University Hospital between April, 1984 and December, 2016. We analyzed the operative results, early and late postoperative complications, and postoperative follow-up rate. The study population comprised 110 CC patients (male/female: 33/77) with a median age at surgery of 4 years, 3 months (range 12 days-17 years). The patients underwent hepaticoduodenostomy (n = 1; 0.9%) or hepaticojejunostomy (n = 109; 99.1%). Late complications included intrahepatic bile duct (IHBD) dilatation (n = 1; 0.9%), IHBD stones (n = 3; 2.7%), and adhesive ileus (n = 4; 3.6%). There was no incidence of biliary carcinoma in this series. The rates of follow-up at our institute within 10 years of surgery and more than 20 years after surgery were 69.2% (18 of 26) and 14.5% (8 of 55), respectively. The follow-up rate after definitive surgery declined with time. Late complications were observed within 20 years, but biliary carcinoma was not observed. The follow-up rate should be increased to detect late complications. Moreover, patient education on long-term follow up is essential to prevent life-threatening events after definitive surgery for CC.

Studies have shown that physiopathological changes to the respiratory system can occur following thoracic and abdominal surgery. Laminectomy is considered to be a peripheral surgical procedure, but it is possible that thoracic spinal surgery exerts a greater influence on lung function. The aim of this study was to evaluate the pulmonary volumes and maximum respiratory pressures of patients undergoing cervical, thoracic or lumbar spinal surgery. Prospective study in a tertiary-level university hospital. Sixty-three patients undergoing laminectomy due to diagnoses of tumors or herniated discs were evaluated. Vital capacity, tidal volume, minute ventilation and maximum respiratory pressures were evaluated preoperatively and on the first and second postoperative days. Possible associations between the respiratory variables and the duration of the operation, surgical diagnosis and smoking status were investigated. Vital capacity and maximum inspiratory pressure presented reductions on the first postoperative day (20.9% and 91.6%, respectively) for thoracic surgery (P = 0.01), and maximum expiratory pressure showed reductions on the first postoperative day in cervical surgery patients (15.3%; P = 0.004). The incidence of pulmonary complications was 3.6%. There were reductions in vital capacity and maximum respiratory pressures during the postoperative period in patients undergoing laminectomy. Surgery in the thoracic region was associated with greater reductions in vital capacity and maximum inspiratory pressure, compared with cervical and lumbar surgery. Thus, surgical manipulation of the thoracic region appears to have more influence on pulmonary function and respiratory muscle action.

Background The goal of this longitudinal study was to examine the associations among psychological factors and pain reports of children and their parents over the 12 month period after pediatric surgery. Materials and methods Included in the study were 83 children aged 8–18 years undergoing major surgery. In each case, the child and one of their parents completed measures of pain intensity and unpleasantness, psychological function, and functional disability at 48–72 hours, 2 weeks (child only), 6 months, and 12 months after surgery. Results The strength of the correlation coefficients between the psychological measures of the parent and their child increased significantly over time. There was a fair level of agreement between parent ratings of child acute and chronic pain (6 months after surgery) and the child’s actual ratings. Parent and child pain anxiety scores 48–72 hours after surgery interacted significantly to predict pain intensity, pain unpleasantness, and functional disability levels 2 weeks after discharge from hospital. Parent pain catastrophizing scores 48–72 hours after surgery predicted child pain intensity reports 12 months later. Conclusion These results raise the possibility that as time from surgery increases, parents exert greater and greater influence over the pain response of their children, so that by 12 months postsurgery mark, parent pain catastrophizing (measured in the days after surgery) is the main risk factor for the development of postsurgical pain chronicity.

Unlike general surgery patients, most of vascular and cardiac surgery patients receive therapeutic anticoagulation during operations. The purpose of this study was to report the incidence of deep venous thrombosis (DVT) among cardiac and vascular surgery patients, compared with general surgery. The American College of Surgeons National Surgical Quality Improvement Program database was queried for all patients who underwent surgical procedures from 2005 to 2010. Patients who developed DVT within 30 days of an operation were identified. The incidence of DVT was compared among vascular, general, and cardiac surgery patients. Risk factors for developing postoperative DVT were identified and compared among these patients. Of total 2,669,772 patients underwent surgical operations in the period between 2005 and 2010. Of all the patients, 18,670 patients (0.69%) developed DVT. The incidence of DVT among different surgical specialties was cardiac surgery (2%), vascular surgery (0.99%), and general surgery (0.66%). The odds ratio for developing DVT was 1.5 for vascular surgery patients and 3 for cardiac surgery patients, when compared with general surgery patients (P < 0.001). The odds ratio for developing DVT after cardiac surgery was 2, when compared with vascular surgery (P < 0.001). The incidence of DVT is higher among vascular and cardiac surgery patients as compared with that of general surgery patients. Intraoperative anticoagulation does not prevent the occurrence of DVT in the postoperative period. These patients should receive DVT prophylaxis in the perioperative period, similar to other surgical patients according to evidence-based guidelines. Copyright © 2015 Elsevier Inc.

It is well known that injuries and surgical procedures in the lower extremities affect bone mineral both in the injured limb and in the contralateral limb. The possible effect on bone mineral after upper extremity surgery is not well studied, and the aim of this study was to study the effect on bone mineral in the calcanei after arthroscopic shoulder surgery. Twenty-two men scheduled for arthroscopic shoulder surgery underwent bone mineral area (BMA) mass measurements in both calcanei using the Calscan DXL device prior to surgery and after 6, 18, 36 and 60 months. On every occasion, the Tegner activity score and EuroQoL 5-dimensions (EQ-5D) were assessed. During 5 years, there was a significant decrease in the BMA in both calcanei (p = 0.003). The Tegner activity score decreased from preinjury to the operation and did not increase significantly after the operation. The EQ-5D increased significantly after the operation. The bone mineral in the calcanei in men during the 5-year study period decreased more than the expected age-dependent decline after arthroscopic shoulder surgery. There was an increase in health-related quality of life as measured with the EQ-5D after arthroscopic Bankart reconstruction. Case-control study, Level III.

Deep infection remains a serious complication of orthopaedic surgery. Knowledge of infection rates and causative organisms is important to guide infection control measures. The aim of the present study was to determine infection rates and causative organisms in elective shoulder surgery. Cases complicated by infection were identified and prospectively recorded over a 2-year period. All patients undergoing elective shoulder surgery in the concurrent period at a single Specialist Upper Limb Unit in the UK were identified from the hospital electronic database. In total, 1574 elective shoulder cases were performed: 1359 arthroscopic (540 with implant insertion) and 215 open (197 with implant insertion). The overall infection rate in open surgery of 2.5% was significantly higher than arthroscopic implant cases at 0.7% ( p  < 0.005). The overall infection rate in implant arthroscopic surgery was significantly higher at 0.7% compared to 0% in non-implant related surgery. ( p  < 0.05). Patients undergoing open shoulder surgery have a significantly higher risk of infection compared to arthroscopic shoulder surgery. Arthroscopic surgery with implant insertion has a statistically significantly higher risk of developing deep infection compared to procedures with no implant insertion. We recommend prophylactic antibiotics in open shoulder surgery and arthroscopic shoulder surgery with implant insertion.

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?

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.

Conflicts of interest (COI) are an emerging area of discussion within the field of plastic surgery. Recently, several reports have found that research studies that disclose COI are associated with publication of positive outcomes. We hypothesize that this association is driven by higher-quality studies receiving industry funding. This study aimed to investigate the association between industry support and study methodological quality. We reviewed all entries in Plastic and Reconstructive Surgery, Annals of Plastic Surgery, and Journal of Plastic, Reconstructive, and Aesthetic Surgery within a 1-year period encompassing 2013. All clinical research articles were analyzed. Studies were evaluated blindly for methodology quality based on a validated scoring system. An ordinal logistic regression model was used to examine the association between methodology score and COI. A total of 1474 articles were reviewed, of which 483 met our inclusion criteria. These articles underwent methodological quality scoring. Conflicts of interest were reported in 28 (5.8%) of these articles. After adjusting for article characteristics in the ordinal logistic regression analysis, there was no significant association between articles with COI and higher methodological scores (P = 0.7636). Plastic surgery studies that disclose COI are not associated with higher methodological quality when compared with studies that do not disclose COI. These findings suggest that although the presence of COI is associated with positive findings, the association is not shown to be driven by higher-quality studies.

Background Few trials of acute kidney injury (AKI) prevention after surgery have been conducted and most observational studies focus on AKI following cardiac surgery. The frequency of, risk factors for, and outcomes after AKI following other types of major surgery have not been well characterized, and may present additional opportunities for trials in AKI. Study Design Observational cohort study. Setting & Participants 3.6 million US veterans followed up from 2004-2011 for the receipt of major surgery (cardiac; general; ear, nose, and throat [ENT], thoracic, vascular, urologic, orthopedic) and post-operative outcomes. Factors Demographics, health characteristics, and type of surgery. Outcomes Post-operative AKI defined by the KDIGO creatinine criteria, post-operative length of stay, end-stage renal disease (ESRD), and mortality. Results Post-operative AKI occurred in 11.8% of the 161,185 major surgery hospitalizations (stage 1, 76%; stage 2, 15%, stage 3 [without dialysis], 7%; AKI requiring dialysis, 2%). Cardiac surgery had the highest post-operative AKI risk (relative risk [RR], 1.22; 95% CI, 1.17-1.27), followed by general (reference), thoracic (RR, 0.92; 95% CI, 0.87-0.98), orthopedic (RR, 0.70; 95% CI, 0.67-0.73), vascular (RR, 0.68; 95% CI, 0.64-0.71), urologic (RR, 0.65; 95% CI, 0.61-0.69), and ENT (RR, 0.32; 95% CI, 0.28-0.37) surgery. Risk factors for post-operative AKI included older age, African-American race, hypertension, diabetes mellitus, and, when eGFR < 90 ml/min/1.73 m2, lower eGFR. Participants with post-operative AKI had longer length of stay (15.8 vs. 8.6 days) and higher rates of 30-day hospital readmission (21% vs. 13%), 1-year ESRD (0.94% vs. 0.05%) and mortality (19% vs. 8%), with similar associations by type of surgery and more severe stage of AKI relating to poorer outcomes. Limitations Urine output was not available to classify AKI; cohort included mostly men. Conclusions AKI was common after major surgery, with similar risk factor and outcome associations across surgery type. These results can inform the design of clinical trials in post-operative AKI to the non-cardiac surgery setting. PMID:26337133

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.

Variability inherent in the duration of surgical procedures complicates surgical scheduling. Modeling the duration and variability of surgeries might improve time estimates. Accurate time estimates are important operationally to improve utilization, reduce costs, and identify surgeries that might be considered outliers. Surgeries with multiple procedures are difficult to model because they are difficult to segment into homogenous groups and because they are performed less frequently than single-procedure surgeries. The authors studied, retrospectively, 10,740 surgeries each with exactly two CPTs and 46,322 surgical cases with only one CPT from a large teaching hospital to determine if the distribution of dual-procedure surgery times fit more closely a lognormal or a normal model. The authors tested model goodness of fit to their data using Shapiro-Wilk tests, studied factors affecting the variability of time estimates, and examined the impact of coding permutations (ordered combinations) on modeling. The Shapiro-Wilk tests indicated that the lognormal model is statistically superior to the normal model for modeling dual-procedure surgeries. Permutations of component codes did not appear to differ significantly with respect to total procedure time and surgical time. To improve individual models for infrequent dual-procedure surgeries, permutations may be reduced and estimates may be based on the longest component procedure and type of anesthesia. The authors recommend use of the lognormal model for estimating surgical times for surgeries with two component procedures. Their results help legitimize the use of log transforms to normalize surgical procedure times prior to hypothesis testing using linear statistical models. Multiple-procedure surgeries may be modeled using the longest (statistically most important) component procedure and type of anesthesia.

Although postoperative atrial fibrillation is common after noncardiac surgery, there is a paucity of data regarding prophylaxis. We sought to determine whether pharmacologic prophylaxis reduces the incidence of postoperative atrial fibrillation after noncardiac surgery. We performed an electronic search of Ovid MEDLINE, the Cochrane central register of controlled trials database, and SCOPUS from inception to September 7, 2016 and included prospective randomized studies in which patients in sinus rhythm underwent noncardiac surgery and examined the incidence of postoperative atrial fibrillation as well as secondary safety outcomes. Twenty-one studies including 11,608 patients were included. Types of surgery included vascular surgery (3465 patients), thoracic surgery (2757 patients), general surgery (2292 patients), orthopedic surgery (1756 patients), and other surgery (1338 patients). Beta-blockers (relative risk [RR] 0.32; 95% confidence interval [CI], 0.11-0.87), amiodarone (RR 0.42; 95% CI, 0.26 to 0.67), and statins (RR 0.43; 95% CI, 0.27 to 0.68) reduced postoperative atrial fibrillation compared with placebo or active controls. Calcium channel blockers (RR 0.55; 95% CI, 0.30 to 1.01), digoxin (RR 1.62; 95% CI, 0.95 to 2.76), and magnesium (RR 0.73; 95% CI, 0.23 to 2.33) had no statistically significant effect on postoperative atrial fibrillation incidence. The incidence of adverse events was comparable across agents, except for increased mortality (RR 1.33; 95% CI, 1.03 to 1.37) and bradycardia (RR 2.74; 95% CI, 2.19 to 3.43) in patients receiving beta-blockers. Pharmacologic prophylaxis with amiodarone, beta-blockers, or statins reduces the incidence of postoperative atrial fibrillation after noncardiac surgery. Amiodarone and statins have a relatively low overall risk of short-term adverse events. Copyright © 2018 Elsevier Inc. All rights reserved.

Oral and maxillofacial surgery has expanded rapidly over the past century. Recognition in France has grown since the first face transplantation in the world performed by Professor Bernard Devauchelle. This speciality, which seems to correspond to a narrow scope of services, actually involves oral, plastic, reconstructive, and cosmetic surgeries of the face. French training for maxillofacial surgeons differs from the Anglo-Saxon course of study. After examining surveys carried out in Great Britain, the United States, and Brazil, the perception of this speciality in the general public and among regular correspondents (general practitioners and dental practitioners) was ascertained. More than 4,000 questionnaires were sent to health care workers and patients attending dental practices. The returned questionnaires concerning recognition of this profession in France were analyzed. Evaluating awareness of maxillofacial surgery among practitioners and the public was of particular interest because it can overlap with several other specialities (ear, nose, and throat; plastic surgery; odontology). The questionnaire included the 20 items used in other similar studies so the results could be compared. Several fields of expertise were identified in maxillofacial surgery, in particular traumatology, surgery for facial birth defects, and orthognathic surgery. Moreover, dental practitioners were found to be the most regular correspondents of maxillofacial surgeons compared with general practitioners. Compared with Anglo-Saxon and Brazilian peers, French recognition of maxillofacial surgery was better. Despite encouraging results, maxillofacial surgery remains a somewhat obscure speciality for health care workers and the general public. Better awareness is necessary for this speciality to become the reference in facial surgery. Copyright © 2011 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.

PURPOSE This study aims to investigate the degree of subjective pain and the satisfaction of patients who have undergone an implant treatment using a computer-guided template. MATERIALS AND METHODS A survey was conducted for 135 patients who have undergone implant surgery with and without the use of the computer-guided template during the period of 2012 and 2013 in university hospitals, dental hospitals and dental clinics that practiced implant surgery using the computer-guided template. Likert scale and VAS score were used in the survey questions, and the independent t-test and One-Way ANOVA were performed (α=.05). RESULTS The route that the subjects were introduced to the computer-guided implant surgery using a surgical template was mostly advices by dentists, and the most common reason for which they chose to undergo such surgery was that it was accurate and safe. Most of them gave an answer that they were willing to recommend it to others. The patients who have undergone the computer-guided implant surgery felt less pain during the operation and showed higher satisfaction than those who have undergone conventional implant surgery. Among the patients who have undergone computer-guided implant surgery, those who also had prior experience of surgery without a computer-guided template expressed higher satisfaction with the former (P<.05). CONCLUSION In this study, it could be seen that the patients who have undergone computer-guided implant surgery employing a surgical template felt less pain and had higher satisfaction than those with the conventional one, and the dentist's description could provide the confidence about the safety of surgery.

The organization of health care establishments and perioperative care are essential for ensuring the quality of care and safety of patients undergoing outpatient surgery. In order to correctly inventory these organizations and practices, in 2013-2014, the French society of anaesthesia and intensive care organized an extensive practical survey in French ambulatory surgery units entitled the "OPERA" study (Organisation periopératoire de l'anesthésie en chirurgie ambulatoire). From among all of the ambulatory surgery centres listed by the Agences régionales de santé (Regional health agencies, France), 206 public and private centres were randomly selected. A structural (typology, organization) survey and a medical-practice survey (focusing on the management of postoperative pain, nausea and vomiting as well as the prevention of venous thromboembolism) were collected and managed by a prospective audit of practices occurring on two randomly selected days. The latter was further accompanied by an additional audit specifically focussing on ten representative procedures: (1) stomatology surgery (third molar removal); (2) knee arthroscopy; (3) surgery of the abdominal wall (including inguinal hernia); (4) perianal surgery; (5) varicose vein surgery; (6) digestive laparoscopy-cholecystectomy; (7) breast surgery (tumourectomy); (8) uterine surgery; (9) hallux valgus and (10) hand surgery (excluding carpal tunnel). Over the 2 days of observation, 7382 patients were included comprising 2174 patients who underwent one of the procedures from the above list. The analysis of these data will provide an overview of the organization of health establishments, the modalities thus supported and compliance with standards.

A comprehensive multi-institutional study on postoperative adjuvant immunotherapy with oral streptococcal preparation OK-432 for patients after gastric cancer surgery. Kyoto Research Group for Digestive Organ Surgery.

PubMed Central

1992-01-01

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

Is nonoperative management of partial distal biceps tears really successful?

Bauer, Tyler M; Wong, Justin C; Lazarus, Mark D

2018-04-01

The current treatment of partial distal biceps tears is a period of nonoperative management, followed by surgery, if symptoms persist. Little is known about the success rate and outcomes of nonoperative management of this illness. We identified 132 patients with partial distal biceps tears through an International Classification of Diseases, Ninth Revision code query of our institution's database. Patient records were reviewed to abstract demographic information and confirm partial tears of the distal biceps tendon based on clinical examination findings and confirmatory magnetic resonance imaging (MRI). Seventy-four patients completed an outcome survey. In our study, 55.7% of the contacted patients who tried a nonoperative course (34 of 61 patients) ultimately underwent surgery, and 13 patients underwent immediate surgery. High-need patients, as defined by occupation, were more likely to report that they recovered ideally if they underwent surgery, as compared with those who did not undergo surgery (odds ratio, 11.58; P = .0138). For low-need patients, the same analysis was not statistically significant (P = .139). There was no difference in satisfaction scores between patients who tried a nonoperative course before surgery and those who underwent immediate surgery (P = .854). An MRI-diagnosed tear of greater than 50% was a predictor of needing surgery (odds ratio, 3.0; P = .006). This study has identified clinically relevant information for the treatment of partial distal biceps tears, including the following: the failure rate of nonoperative treatment, the establishment of MRI percent tear as a predictor of failing nonoperative management, the benefit of surgery for the high-need occupational group, and the finding that nonoperative management does not negatively affect outcome if subsequent surgery is necessary.

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.

To compare visual acuity outcomes, vision-related quality of life, and complications related to cataract surgery in eyes with and without glaucoma. Retrospective cohort study. Cataract surgery outcomes in cases with and without glaucoma from the Veterans Affairs Ophthalmic Surgical Outcomes Data Project were compared. We identified 608 glaucoma cases and 4306 controls undergoing planned cataract surgery alone. After adjusting for age, pseudoexfoliation, small pupil, prior ocular surgery, and anterior chamber depth, we found that glaucoma cases were more likely to have posterior capsular tear with vitrectomy (odds ratio [OR] 1.8, P = .03) and sulcus intraocular lens placement (OR 1.65, P = .03) during cataract surgery. Glaucoma cases were more likely to have postoperative inflammation (OR 1.73, P < .0001), prolonged elevated intraocular pressure (OR 2.96, P = .0003), and additional surgery within 30 days (OR 1.92, P = .03). Mean best-corrected visual acuity (BCVA) and Visual Function Questionnaire (VFQ) scores significantly improved after cataract surgery in both groups (P < .0001), but there were larger improvements in BCVA (P = .01) and VFQ composite scores (P < .0001) in the nonglaucoma vs the glaucoma group. A total of 3621 nonglaucoma cases (94.1%) had postoperative BCVA 20/40 or better, compared to 466 glaucoma cases (89.6%) (P = .0003). Eyes with glaucoma are at increased risk for complications and have more modest visual outcomes after cataract surgery compared to eyes without glaucoma. Despite this, glaucoma patients still experience significant improvement in vision-related outcomes after cataract extraction. Further study is needed to explore potential factors that influence cataract surgery outcomes in glaucomatous eyes. Published by Elsevier Inc.

Recent data suggest patients are seeking aesthetic surgery to improve their appearance on Instagram and other social media. Despite the rising influence of Instagram in plastic surgery, few academic publications address Instagram, let alone evaluate its utilization in plastic surgery. We set out to answer the following three questions: 1) what plastic surgery-related content is being posted to Instagram; 2) who is posting this content; and 3) what specific hashtags are they using? Our study queried 21 Instagram plastic surgery-related hashtags. Content analysis was used to qualitatively evaluate each of the nine "top" posts associated with each hashtag (189 posts). Duplicate posts and those not relevant to plastic surgery were excluded. A total of 1,789,270 posts utilized the 21 hashtags sampled in this study. Of the top 189 posts for these 21 queried hashtags, 163 posts met inclusion criteria. Plastic surgeons eligible for membership in American Society for Aesthetic Plastic Surgery (ASAPS) accounted for only 17.8% of top posts, whereas noneligible physicians accounted for 26.4%. All nonplastic surgery trained physicians marketed themselves as "cosmetic surgeons." Nine top posts (5.5%) were by nonphysicians, including dentists, spas with no associated physician, and a hair salon. The majority of these posts were self-promotional (67.1%) as opposed to educational (32.9%). Board-certified plastic surgeons were significantly more likely to post educational content to Instagram as compared to nonplastic surgeons (62.1% vs 38.1%, P = 0.02). ASAPS eligible board-certified plastic surgeons are underrepresented amongst physicians posting top plastic surgery-related content to Instagram. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

To study patient sources of knowledge about cataract surgical services, and strategies for financing surgery in rural China. Cross-sectional case series. Patients undergoing cataract surgery by local surgeons in a government, village-level facility in Sanrao, Guangdong between 8 August and 31 December 2005 were examined and had standardised interviews an average of 12 months after surgery. Of 313 eligible patients, 239 (76%) completed the questionnaire. Subjects had a mean (SD) age of 69.9 (10.2) years, 36.4% (87/239) were male, and 87.0% (208/239) had been blind (presenting visual acuity < or = 6/60) before surgery. Word-of-mouth advertising was particularly important: 198 (85.0%) of the subjects knew a person who had undergone cataract surgery, of whom 191 (96.5%) had had cataract surgery at Sanrao itself. Over 70% of subjects (166/239) watched TV daily, whereas 80.0% (188/239) "never" read the newspaper. Nearly two-thirds of suggestions from participants (n = 211, 59.6%) favoured either TV advertisements or word-of-mouth to publicise the programme. While the son or daughter had paid for surgery in over 70% of cases (164/233), the patient's having paid without help was the sole predictor of undergoing second-eye surgery (OR 2.27 (95% CI 1.01 to 5.0, p = 0.04)). Strategies to increase uptake of cataract surgery in rural China may benefit from enhancing word-of-mouth advertising (such as with pseudophakic motivators), using television advertising where affordable, and micro-credit or other programmes to enable patients to pay their own fees, thus increasing uptake of second-eye surgery.

2011-05-01

The aim of this retrospective chart review of the patients who had septal surgery with or without turbinate surgery was to compare the postoperative complication rates according to the time of intranasal-splint (INS) removal. The data of 137 patients who underwent septal surgery with or without turbinate surgery at 2 different hospitals of Acıbadem Health Care Group between January 2007 and March 2009 were retrospectively evaluated. The patients who had these risk factors were eliminated, and 96 patients were included in this study. The patients were divided into 2 groups according to splint-removal time. The first group comprises patients whose nasal splints were removed in 24 hours after surgery, and the second group comprises patients whose splints were removed 5 days after the surgery. Any bleeding, septal hematoma, and synechia after pack removal were recorded. Analysis of the rate of complications was done with the χ test. Sixty-five male and 31 female patients with a mean age of 32.4 years (range, 18-57 years) were included in the study groups. Septal surgeries were performed in association with turbinate surgery in all 96 patients. These patients were divided into 2 groups. In the first group (n = 50), INSs were removed in 24 hours after surgery. In the second group (n = 46), INSs were removed 5 days after surgery. Bleeding within the first postoperative week was not recorded in both groups. Late bleeding was recorded in 2% (n = 1) of group 1 and in 2.17% (n = 1) in group 2. Septal hematoma and synechia were not recorded in none of the groups. The results were not statistically significant (P = 1). The routine use of INSs after septoplasty and removing them 24 hours after septoplasty are sufficient to avoid postoperative complications, and it minimizes postoperative discomfort.

Habr-Gama, Angelita; Perez, Rodrigo Oliva; Proscurshim, Igor

Background: The optimal interval between neoadjuvant chemoradiation therapy (CRT) and surgery in the treatment of patients with distal rectal cancer is controversial. The purpose of this study is to evaluate whether this interval has an impact on survival. Methods and Materials: Patients who underwent surgery after CRT were retrospectively reviewed. Patients with a sustained complete clinical response (cCR) 1 year after CRT were excluded from this study. Clinical and pathologic characteristics and overall and disease-free survival were compared between patients undergoing surgery 12 weeks or less from CRT and patients undergoing surgery longer than 12 weeks from CRT completion andmore » between patients with a surgery delay caused by a suspected cCR and those with a delay for other reasons. Results: Two hundred fifty patients underwent surgery, and 48.4% had CRT-to-surgery intervals of 12 weeks or less. There were no statistical differences in overall survival (86% vs. 81.6%) or disease-free survival rates (56.5% and 58.9%) between patients according to interval ({<=}12 vs. >12 weeks). Patients with intervals of 12 weeks or less had significantly higher rates of Stage III disease (34% vs. 20%; p = 0.009). The delay in surgery was caused by a suspected cCR in 23 patients (interval, 48 {+-} 10.3 weeks). Five-year overall and disease-free survival rates for this subset were 84.9% and 51.6%, not significantly different compared with the remaining group (84%; p = 0.96 and 57.8%; p = 0.76, respectively). Conclusions: Delay in surgery for the evaluation of tumor response after neoadjuvant CRT is safe and does not negatively affect survival. These results support the hypothesis that shorter intervals may interrupt ongoing tumor necrosis.« less

Surgery remains the mainstay in the diagnosis and management of endometriosis. The number of surgeries performed for endometriosis worldwide is ever increasing, however do we have evidence for improvement of infertility after the surgery and do we exaggerate the magnitude of effect of surgery when we counsel our patients? The management of patients who failed the surgery could be by repeat surgery or assisted reproduction. What evidence do we have for patients who fail assisted reproduction and what is their best chance for achieving pregnancy? In this study we reviewed the evidence-based practice pertaining to the outcome of surgery assisted infertility associated with endometriosis. Manuscripts published in PubMed and Science Direct as well as the bibliography cited in these articles were reviewed. Patients with peritoneal endometriosis with mild and severe disease were addressed separately. Patients who failed the primary surgery and managed by repeat or assisted reproduction technology were also evaluated. Patients who failed assisted reproduction and managed by surgery were also studied to determine of the best course of action. In patients with minimal and mild pelvic endometriosis, excision or ablation of the peritoneal endometriosis increases the pregnancy rate. In women with severe endometriosis, controlled trials suggested an improvement of pregnancy rate. In women with ovarian endometrioma 4 cm or larger ovarian cystectomy increases the pregnancy rate, decreases the recurrence rate, but is associated with decrease in ovarian reserve. In patients who have failed the primary surgery, assisted reproduction appears to be significantly more effective than repeat surgery. In patients who failed assisted reproduction, the management remains to be extremely controversial. Surgery in expert hands might result in significant improvement in pregnancy rate. In women with minimal and mild endometriosis, surgical excision or ablation of endometriosis is recommended as first line with doubling the pregnancy rate. In patients with moderate and severe endometriosis surgical excision also is recommended as first line. In patients who failed to conceive spontaneously after surgery, assisted reproduction is more effective than repeat surgery. Following surgery, the ovarian reserve may be reduced as determined by Anti Mullerian Hormone. The antral follicle count is not significantly reduced. In women with large endometriomas > 4 cm the ovarian endometrioma should be removed. In women who have failed assisted reproduction, further management remains controversial in the present time.

The purpose of this study was to measure and compare the working time for virtual surgical planning (VSP) in orthognathic surgery in a largely office-based workflow in comparison with conventional surgical planning (CSP) regarding the type of surgery, staff involved, and working location. This prospective cohort study included patients treated with orthognathic surgery from May to December 2016. For each patient, both CSP with manual splint fabrication and VSP with fabrication of computer-aided design-computer-aided manufacturing splints were performed. The predictor variables were planning method (CSP or VSP) and type of surgery (single or double jaw), and the outcome was time. Descriptive and analytic statistics, including analysis of variance for repeated measures, were computed. The sample was composed of 40 patients (25 female and 15 male patients; mean age, 24.6 years) treated with single-jaw surgery (n = 18) or double-jaw surgery (n = 22). The mean times for planning single-jaw surgery were 145.5 ± 11.5 minutes for CSP and 109.3 ± 10.8 minutes for VSP, and those for planning double-jaw surgery were 224.1 ± 11.2 minutes and 149.6 ± 15.3 minutes, respectively. Besides the expected result that the working time was shorter for single-versus double-jaw surgery (P < .001), it was shown that VSP shortened the working time significantly versus CSP (P < .001). The reduction of time through VSP was relatively stronger for double-jaw surgery (P < .001 for interaction). All differences between CSP and VSP regarding profession (except for the surgeon's time investment) and location were statistically significant (P < .01). The surgeon's time to plan single-jaw surgery was 37.0 minutes for CSP and 41.2 minutes for VSP; for double-jaw surgery, it was 53.8 minutes and 53.6 minutes, respectively. Office-based VSP for orthognathic surgery was significantly faster for single- and double-jaw surgery. The time investment of the surgeon was equal for both methods, and all other steps of the workflow differed significantly compared with CSP.

Health economic evaluations inform healthcare resource allocation decisions for treatment options for obesity including bariatric/metabolic surgery. As an important advance on existing systematic reviews, we aimed to capture, summarize and synthesize a diverse range of economic evaluations on bariatric surgery. Studies were identified by electronic screening of all major biomedical/economic databases. Studies included if they reported any quantified health economic cost and/or consequence with a measure of effect for any type of bariatric surgery from 1995 to September 2015. Study screening, data extraction and synthesis followed international guidelines for systematic reviews. Six thousand one hundred eighty-seven studies were initially identified. After two levels of screening, 77 studies representing 17 countries (56% USA) were included. Despite study heterogeneity, common themes emerged, and important gaps were identified. Most studies adopted the healthcare system/third-party payer perspective; reported costs were generally healthcare resource use (inpatient/shorter-term outpatient). Out-of-pocket costs to individuals, family members (travel time, caregiving) and indirect costs due to lost productivity were largely ignored. Costs due to reoperations/complications were not included in one-third of studies. Body-contouring surgery included in only 14%. One study evaluated long-term waitlisted patients. Surgery was cost-effective/cost-saving for severely obese with type 2 diabetes mellitus. Study quality was inconsistent. There is a need for studies that assume a broader societal perspective (including out-of-pocket costs, costs to family and productivity losses) and longer-term costs (capture reoperations/complications, waiting, body contouring), and consequences (health-related quality-of-life). Full economic evaluation underpinned by reporting standards should inform prioritization of patients (e.g. type 2 diabetes mellitus with body mass index 30 to 34.9 kg/m(2) or long-term waitlisted) for surgery. © 2016 World Obesity. © 2016 World Obesity.

The expansion of the obesity epidemic is accompanied with an increase in bariatric procedures, in particular in women of reproductive age. The weight loss induced by the surgery is believed to reverse the negative impact of overweight and obesity on female reproduction, however, research is limited to in particular retrospective cohort studies and a growing number of small case-series and case-(control) studies. AURORA is a multicenter prospective cohort study. The main objective is to collect long-term data on reproductive outcomes before and after bariatric surgery and in a subsequent pregnancy. Women aged 18-45 years are invited to participate at 4 possible inclusion moments: 1) before surgery, 2) after surgery, 3) before 15 weeks of pregnancy and 4) in the immediate postpartum period (day 3-4). Depending on the time of inclusion, data are collected before surgery (T1), 3 weeks and 3, 6, 12 or x months after surgery (T2-T5) and during the first, second and third trimester of pregnancy (T6-T8), at delivery (T9) and 6 weeks and 6 months after delivery (T10-T11). Online questionnaires are send on the different measuring moments. Data are collected on contraception, menstrual cycle, sexuality, intention of becoming pregnant, diet, physical activity, lifestyle, psycho-social characteristics and dietary supplement intake. Fasting blood samples determine levels of vitamin A, D, E, K, B-1, B-12 and folate, albumin, total protein, coagulation parameters, magnesium, calcium, zinc and glucose. Participants are weighted every measuring moment. Fetal ultrasounds and pregnancy course and complications are reported every trimester of pregnancy.

Loco-regional treatment failure after radiotherapy with or without chemotherapy and/or prior surgery represents a significant portion of head and neck cancer patients. Due to a wide array of biological interactions, these patients have a significantly increased risk of complications related to wound healing. Review of the current literature was performed for wound healing pathophysiology, head and neck salvage surgery, and wound therapy. The biology of altered wound healing in the face of previous surgery and chemoradiotherapy is well described in the literature. This is reflected in multiple clinical studies demonstrating increased rates of wound healing complications in salvage surgery, most commonly in the context of previous irradiation. Despite these disadvantages, multiple studies have described strategies to optimize healing outcomes. The literature supports preoperative optimization of known wound healing factors, adjunctive wound care modalities, and microvascular free tissue transfer for salvage surgery defects and wounds. Previously treated head and neck patients requiring salvage surgery have had a variety of disadvantages related to wound healing. Recognition and treatment of these factors can help to reverse adverse tissue conditions. A well-informed approach to salvage surgery with utilization of free vascularized or pedicled tissue transfer as well as optimizing wound healing factors is essential to obtaining favorable outcomes.

Marques, Inês; Captivo, M Eugénia; Vaz Pato, Margarida

2015-09-01

Resource rationalization and reduction of waiting lists for surgery are two main guidelines for hospital units outlined in the Portuguese National Health Plan. This work is dedicated to an elective surgery scheduling problem arising in a Lisbon public hospital. In order to increase the surgical suite's efficiency and to reduce the waiting lists for surgery, two objectives are considered: maximize surgical suite occupation and maximize the number of surgeries scheduled. This elective surgery scheduling problem consists of assigning an intervention date, an operating room and a starting time for elective surgeries selected from the hospital waiting list. Accordingly, a bicriteria surgery scheduling problem arising in the hospital under study is presented. To search for efficient solutions of the bicriteria optimization problem, the minimization of a weighted Chebyshev distance to a reference point is used. A constructive and improvement heuristic procedure specially designed to address the objectives of the problem is developed and results of computational experiments obtained with empirical data from the hospital are presented. This study shows that by using the bicriteria approach presented here it is possible to build surgical plans with very good performance levels. This method can be used within an interactive approach with the decision maker. It can also be easily adapted to other hospitals with similar scheduling conditions.

The progress of medicine has largely been due to research, and for surgery, in particular, the experimental surgical laboratory has been considered fundamental to the surgeon's education. In this study, a general view of experimental surgery is given in animal models based on bioethical norms as well as to design, create and apply different surgical procedures before performing in humans. Experimental surgery also facilitates surgical teaching and promotes the surgeon's scientific reasoning. Methods. This is a retrospective and descriptive study. Data were collected from direct and indirect sources of available publications on the historical, bioethical and educational aspects of medicine, focusing on surgery. The important facts corresponding to the field of experimental surgery and applicable in Mexico were selected. Concepts of experimental surgical models and of the experimental surgery laboratory were described. Bioethical considerations are emphasized for care of experimental animals. Finally, this work focuses on the importance of surgical experimentation in current and future development of the surgical researcher. Conclusions. Experimentation with animal models in a surgical laboratory is essential for surgical teaching and promotes development of the scientific thought in the surgeon. It is necessary for surgical research and is fundamental for making progress in surgery, treatment and medicine as science.

Studies show that patients recall less than half of the information given by their physicians. Use of video in medicine increases patient comprehension and satisfaction and decreases anxiety. However, studies have not elaborated on video content. To use principles of learning with multimedia to improve the Mohs surgery consultation. The authors developed 2 informational videos on Mohs surgery: traditional versus narrative. The focus of the traditional video was purely didactic. The narrative video included patient testimonials, patient-physician interaction, and animations. New Mohs surgery patients viewed either the traditional (n = 40) or the narrative video (n = 40). Existing Mohs surgery patients (n = 40) viewed both videos. Both groups answered questionnaires about their satisfaction. For new Mohs surgery patients, no significant difference was found between the traditional and the narrative video groups because respondent satisfaction was high for both video formats. For existing Mohs surgery patients, all respondents (100%) reported that videos were helpful for understanding Mohs surgery; however, the majority would recommend the narrative over the traditional format (72.5% vs 27.5%, p = .01). Technology is useful for patient education because all patients preferred seeing a video to no video. Further research is needed to optimize effective multimedia use in patient education.

The importance of minimally invasive surgery in urology has constantly increased in the last 20 years. Endoscopic resection of prostate and bladder tumors is actually a gold standard with many advantages for patients. To analyze the problems related to the ergonomic conditions faced by urologist during video endoscopic surgery by review of the recent literature. All evidence-based experimental ergonomic studies conducted in the fields of urology endoscopic surgery and applied ergonomics for other professions working with a display were identified by PubMed searches. Data from ergonomic studies were evaluated in terms of efficiency as well as comfort and safety aspects. Constraint postures for urologists are described and ergonomic requirements for optimal positions are discussed. The ergonomics of urological endoscopic surgery place urologists at risk for potential injury. The amount of neck flexion or extension, the amount of shoulder girdle adduction or abduction used, and stability of the upper extremities during surgery; which are maintained in a prolonged static posture; are the main risk factors. All these constraints may lead to muscle and joint fatigue, pain, and eventual musculoskeletal injury. Moreover, these issues may impact surgical accuracy. Urologist posture, operating period, training are important ergonomic factor during video surgery to prevent musculoskeletal disorders.

Virtual reality (VR)-based simulators offer numerous benefits and are very useful in assessing and training surgical skills. Virtual reality-based simulators are standard in some surgical subspecialties, but their actual use in spinal surgery remains unclear. Currently, only technical reviews of VR-based simulators are available for spinal surgery. Thus, we performed a systematic review that examined the existing research on VR-based simulators in spinal procedures. We also assessed the quality of current studies evaluating VR-based training in spinal surgery. Moreover, we wanted to provide a guide for future studies evaluating VR-based simulators in this field. This is a systematic review of the current scientific literature regarding VR-based simulation in spinal surgery. Five data sources were systematically searched to identify relevant peer-reviewed articles regarding virtual, mixed, or augmented reality-based simulators in spinal surgery. A qualitative data synthesis was performed with particular attention to evaluation approaches and outcomes. Additionally, all included studies were appraised for their quality using the Medical Education Research Study Quality Instrument (MERSQI) tool. The initial review identified 476 abstracts and 63 full texts were then assessed by two reviewers. Finally, 19 studies that examined simulators for the following procedures were selected: pedicle screw placement, vertebroplasty, posterior cervical laminectomy and foraminotomy, lumbar puncture, facet joint injection, and spinal needle insertion and placement. These studies had a low-to-medium methodological quality with a MERSQI mean score of 11.47 out of 18 (standard deviation=1.81). This review described the current state and applications of VR-based simulator training and assessment approaches in spinal procedures. Limitations, strengths, and future advancements of VR-based simulators for training and assessment in spinal surgery were explored. Higher-quality studies with patient-related outcome measures are needed. To establish further adaptation of VR-based simulators in spinal surgery, future evaluations need to improve the study quality, apply long-term study designs, and examine non-technical skills, as well as multidisciplinary team training.

The purpose of this study was to evaluate the feasibility and acceptability of a multimedia self-management (MSM) intervention to prepare patients and family caregivers for lung surgery. This is a quasi-experimental, 2-group, sequential enrollment pilot study of a 4-session multimedia intervention (audio/visual + print) to enhance self-management and quality of life (QOL) for patients and family caregivers. The intervention, Preparing for Lung Surgery, begins before surgery, and continues through hospitalization and discharge, with 2 telephone support sessions after discharge. Outcomes were assessed before surgery (preintervention), at discharge, and 2 to 4 weeks postdischarge (postintervention). Patient outcomes were assessed using the Functional Assessment of Cancer Therapy-General (QOL), MD Anderson Symptom Inventory and Functional Assessment of Cancer Therapy-Pulmonary Symptom Index (symptoms), self-efficacy, surgery-related knowledge, and patient activation. Family caregiver outcomes included City of Hope-QOL-Family (QOL), Caregiver Burden Scale, and knowledge. Paired t tests were used for exploratory evaluations of score changes from pre- to postintervention. Sixty participants (38 patients, 22 family caregivers) enrolled in the study (70% accrual). Postintervention scores were significantly improved for patients' emotional QOL (P = .001). Trends for improvements were observed for patient self-efficacy, surgery-related knowledge, and activation. Family caregivers' surgery-related knowledge was significantly improved (P = .02). Overall, participants were highly satisfied with the acceptability/usability of the intervention (3.6-3.7 of 4.0). A standardized MSM intervention was feasible and acceptable in supporting readiness and preparedness for lung surgery and postoperative recovery. A larger randomized trial is needed to verify the impact of the MSM intervention on patient/family caregiver outcomes and health care resource use. Copyright © 2017 Elsevier Inc.

To evaluate pregnancy outcome and rates of anemia in patients following bariatric operation in comparison with obese pregnant women. A retrospective population-based study comparing pregnancy outcome of patients following bariatric with the obese population was conducted. Multivariate logistic regression models were constructed to control for confounders. To evaluate the change in hemoglobin levels, we included women who had one pregnancy before the bariatric surgery and one following the surgery or two pregnancies for women with obesity. This study included 326 women who had one pregnancy before and after a bariatric surgery and 1612 obese women who had at least two consecutive deliveries. Using a multivariable logistic regression model, controlling for confounders such as maternal age, patients following bariatric surgery had lower rates of gestational diabetes mellitus (OR 0.7; 95% CI 0.5-0.9; p = 0.49) and macrosomia (OR 0.3; 95% CI 0.2-0.5; p < 0.001) as compared with obese parturients. Women post bariatric surgery were more likely to be anemic (hemoglobin <10 g/dL) as compared to obese parturients (48% versus 37%; OR, 1.5; 95% CI, 1.2-1.9; p < 0.001). A significant decline in hemoglobin level was noted in patients following bariatric surgery (a decline of 0.33 g/dL versus 0.18 g/dL between two consecutive pregnancies of obese women). Using another multivariable model with anemia as the outcome variable, bariatric was noted as a risk factor for anemia (adjusted OR = 1.45, 95%CI 1.13-1.86, p = 0.004). Women following bariatric surgery have lower risk for gestational diabetes mellitus and fetal macrosomia as compared with obese parturients. Nevertheless, bariatric surgery is a risk factor for anemia.

QoR-40, a 40-item questionnaire on quality of recovery from anaesthesia, has been shown to measure health status after surgery. Our aim was to evaluate the incidence of poor quality of recovery in our Post Anaesthesia Care Unit and to compare their QoR-40 scores before surgery and 3 months later. A prospective observational study was conducted in adult patients consecutively admitted from 18 June to 12 July 2012. The follow-up period was 3 months. We exclude patients submitted to cardiac surgery, neurosurgery, obstetric surgery and with a mini-mental state examination test score lower than 25. The primary endpoint was quality of recovery measured with the validated Portuguese for Portugal version of the QoR-40 before surgery (T0), 24h after surgery (T1) and 3 months after (T2). A total of 114 patients completed the study. Mean QoR-40 score was 169 and patients with poor quality of recovery were identified if their QoR-40 score was lesser than 142. This occurred in 26 patients (24%). Global median scores for patients with poor quality of recovery were lower at T0 (121 vs. 184, p<0.001), at T1 (120 vs. 177, p<0.001) and at T2 (119 vs. 189, p<0.001). Patients with poor quality of recovery had lower quality of life. This fact may allow earlier and more effective interventions, in order to improve quality of life after surgery. Beside its utility after surgery, QoR-40 may be important prior to surgery to identify patients who will develop a poor quality of recovery. Copyright © 2015 Sociedade Brasileira de Anestesiologia.

The incisions during orthognathic surgery are classically performed with conventional scalpel or electrocautery. Considering that the high-power diode laser surgery may provide advantages when compared to conventional incision techniques, the current study aimed to present a prospective case series of patients submitted to circumvestibular incision for Le Fort I osteotomy. Ten patients with dentofacial deformities who underwent to rapid assisted maxillary expansion or bimaxillary orthognathic surgery were enrolled in the study. All incisions were performed by a single surgeon using an 808-nm diode laser, with an optical fiber of 600 μm, at a power of 2.5 W, in a continuous-wave mode. The performance of the incision was evaluated by incision velocity, bleeding, edema, secondary infection, clinical healing, and pain. The velocity of the incision ranged from 0.10 to 0.20 mm/s (mean 0.13 ± 0.03 mm/s). Considering bleeding during the soft tissue incision, all surgeries were classified as absent bleeding. All patients presented a clinical healing of the surgical wound in a period that range from 3 to 5 weeks and experienced swelling during the follow-up period. On average, approximately 50% of the swelling had resolved after the third postoperative week, and 28.8% of swelling remained after 2 months after the surgery. The pain decreased after 2 and 3 days, and 90.0% of the patients reported no pain after 7 postoperative days. High-power diode laser is effective and safety during circumvestibular incisions for Le Fort I osteotomy in orthognathic surgery decreasing bleeding, surgery time, pain, and edema after orthognathic surgery.

To analyze the visual outcome after cataract surgery. Cataract surgery clinics in 15 European countries. Database study. Data were drawn from case series of cataract extractions reported to the European Registry of Quality Outcomes for Cataract and Refractive Surgery database. These data were entered into the database via the Web by surgeons or by transfer from existing national registries or electronic medical record systems. The database contains individual anonymous data on preoperative, intraoperative, and postoperative measurements. Data on 368,256 cataract extractions were available for analysis. The best visual outcome was achieved in age groups 40 to 74 years, and men showed a higher percentage of excellent vision (1.0 [20/20] or better) than women. A corrected distance visual acuity (CDVA) of 0.5 (20/40) or better and of 1.0 (20/20) or better was achieved in 94.3% and 61.3% of cases, respectively. Ocular comorbidity and postoperative complications were the strongest influences on the visual outcome; however, surgical complications and ocular changes requiring complex surgery also had a negative influence. Deterioration of visual acuity after the surgery (n= 6112 [1.7% of all cases]) was most common in patients with a good preoperative visual acuity. The visual outcomes of cataract surgery were excellent, with 61.3% of patients achieving a corrected distance visual acuity of 1.0 (20/20) or better. Age and sex influenced the visual outcomes, but the greatest influences were short-term postoperative complications, ocular comorbidity, surgical complications, and complex surgery. A weakness of the study could be that some of the data is self-reported to the registry. Copyright © 2013 ASCRS and ESCRS. Published by Elsevier Inc. All rights reserved.

Numerous authors have sought to describe genotype-phenotype correlations in cystic fibrosis (CF), notably to pancreatic insufficiency and lung disease. However, few studies have focused on the association between the F508del genotype and response to sinus surgery. The objective of this study is to assess the effect of the F508del genotype on sinonasal disease severity and outcomes following functional endoscopic sinus surgery (FESS) in a pediatric population. A retrospective chart review of 153 children with CF seen at a tertiary care pediatric hospital from 1995 to 2008 was performed. Patients were classified into one of three groups according to F508del genotype, either as homozygous, heterozygous or not carrying a F508del mutation. The sinonasal disease phenotype of the three groups was compared based on clinical and radiological findings, extent of endoscopic sinus surgery and rate of revision surgery. The relationship between the F508del genotype and pancreatic insufficiency was confirmed (p<0.05). There was no association between the F508del genotype and increased need for FESS (p=0.75). Moreover, no association was established between F508del homozygosity and presence of nasal polyps, Lund-Mackay score, extent of surgery or length of postoperative hospitalization. The rates of revision surgery did not differ significantly among the three genotypes analyzed (p=0.59). There is no clear association between the F508del genotype and an increased need for FESS, extent of surgery, or revision surgery. Given the phenotypic variability of sinonasal disease in patients with CF, a prospective study is needed to better understand outcomes following FESS and the contribution of gene modifiers to this effect.

Summary Statement Impaired olfaction, identified in 33% of patients undergoing cardiac surgery, was associated with the adjusted risk for postoperative delirium but not cognitive decline. Objectives The prevalence and significance of impaired olfaction is not well characterized in patients undergoing cardiac surgery. Because impaired olfaction has been associated with underlying neurologic disease, impaired olfaction may identify patients who are vulnerable to poor neurological outcomes in the perioperative period. The objective of this study was to determine the prevalence of impaired olfaction among patients presenting for cardiac surgery and the independent association of impaired olfaction with postoperative delirium and cognitive decline. Design Nested prospective cohort study Setting Academic hospital Participants 165 patients undergoing coronary artery bypass and/or valve surgery Measurements Olfaction was measured using the Brief Smell Identification Test, with impaired olfaction defined as an olfactory score < 5th percentile of normative data. Delirium was assessed using a validated chart-review method. Cognitive performance was assessed using a neuropsychological testing battery at baseline and 4–6 weeks after surgery. Results Impaired olfaction was identified in 54 of 165 patients (33%) prior to surgery. Impaired olfaction was associated with increased adjusted risk for postoperative delirium (relative risk [RR] 1.90, 95% CI 1.17–3.09; P=0.009). There was no association between impaired olfaction and change in composite cognitive score in the overall study population. Conclusion Impaired olfaction is prevalent in patients undergoing cardiac surgery and is associated with increased adjusted risk for postoperative delirium, but not cognitive decline. Impaired olfaction may identify unrecognized vulnerability for postoperative delirium among patients undergoing cardiac surgery. PMID:25597555

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.

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.

Structured Abstract Objective This study sought to measure the incidence of perioperative beta-blocker non-compliance by patients who were prescribed chronic beta blocker therapy and presented for surgery from home. The effect of patient non-compliance on day of surgery presenting heart rate was also examined. Design Prospective observational study with outcome data obtained from review of the medical record. Setting The preoperative clinic and operating rooms of a Veterans Administration hospital. Participants Patients on chronic beta blocker therapy who presented from home for surgery. Interventions None. Measurements and Main Results Demographic and comorbidity data as well as data on self-reported compliance to beta-blocker therapy, initial day of surgery vital signs, and recent ambulatory vital signs were collected. Ten out of fifty subjects (20%; 95% CI = 9-31%) reported not taking their day of surgery beta-blocker. These self-reported non-adherers demonstrated a higher presenting heart rate on the day of surgery vs. adherent subjects (median of 78 beats per minute vs. 65 beats per minute, p=0.02 by Wilcoxon Rank-Sum Test). The difference-in-difference between baseline primary care and day of surgery heart rate was also statistically significant between compliant and non-compliant subjects (-7 beats per minute vs. +12.5 beats per minute, p<0.00001). Conclusions Patient self-report and physiologic data documented failure to take beta-blockers and possible beta-blocker withdrawal in 20% of patients who presented for surgery from home. If these findings are confirmed in larger studies, improved patient understanding of and compliance with medication instructions during preoperative visits should be a focus of future quality improvement initiatives.

Variable Operative Experience in Hand Surgery for Plastic Surgery Residents.

PubMed

Silvestre, Jason; Lin, Ines C; Levin, Lawrence Scott; Chang, Benjamin

Efforts to standardize hand surgery training during plastic surgery residency remain challenging. We analyze the variability of operative hand experience at U.S. plastic surgery residency programs. Operative case logs of chief residents in accredited U.S. plastic surgery residency programs were analyzed (2011-2015). Trends in fold differences of hand surgery case volume between the 10th and 90th percentiles of residents were assessed graphically. Percentile data were used to calculate the number of residents achieving case minimums in hand surgery for 2015. Case logs from 818 plastic surgery residents were analyzed of which a minority were from integrated (35.7%) versus independent/combined (64.3%) residents. Trend analysis of fold differences in case volume demonstrated decreasing variability among procedure categories over time. By 2015, fold differences for hand reconstruction, tendon cases, nerve cases, arthroplasty/arthrodesis, amputation, arterial repair, Dupuytren release, and neoplasm cases were below 10-fold. Congenital deformity cases among independent/combined residents was the sole category that exceeded 10-fold by 2015. Percentile data suggested that approximately 10% of independent/combined residents did not meet case minimums for arterial repair and congenital deformity in 2015. Variable operative experience during plastic surgery residency may limit adequate exposure to hand surgery for certain residents. Future studies should establish empiric case minimums for plastic surgery residents to ensure hand surgery competency upon graduation. Copyright © 2017 Association of Program Directors in Surgery.

THIS STUDY REPORTS ON QUALITATIVE research conducted in the UK with people with Parkinson’s Disease and their relatives on the subject of “sham surgery.” It explores attitudes toward sham surgery and reasoning about hypothetical participation in a sham-controlled trial. Results showed that attitudes toward sham surgery may not necessarily predict trial participation behavior. A small majority of interviewees deemed sham surgery ethically acceptable with certain provisos, but hypothetical participation was driven primarily by disease severity and a lack of standard treatment options, with a preference for receiving the real surgery over sham. Ethical implications for patient equipoise and the autonomy of patients’ research participation decisions are discussed. PMID:22850140

Robots have been successfully used in commercial industry and have enabled humans to perform tasks which are repetitive, dangerous and requiring extreme force. Their role has evolved and now includes many aspects of surgery to improve safety and precision. Orthopaedic surgery is largely performed on bones which are rigid immobile structures which can easily be performed by robots with great precision. Robots have been designed for use in orthopaedic surgery including joint arthroplasty and spine surgery. Experimental studies have been published evaluating the role of robots in arthroscopy and trauma surgery. In this article, we will review the incorporation of robots in orthopaedic surgery looking into the evidence in their use. © The Authors, published by EDP Sciences, 2017.

Patients with cervical spondylosis myelopathy (CSM) and complicated with hypertension are often experiencing a blood pressure decrease after taking cervical decompressive surgery in clinical observations, but how this blood pressure reduction is associated with the surgery, which cut cervical sympathetic nervous, has never been rigorously assessed. Thus, the purpose of this study is to investigate the effect of cervical decompressive surgery on blood pressure among CSM patients with hypertension. The study will be a time series cohort study. Fifty eligible patients will be selected consecutively from the Peking University First Hospital. Two 24-h ambulatory blood pressure measurement (ABPM) will be taken before the surgery, apart by at least 3 days. The patients will be followed up for another two ABPMs at 1 and 3 months after the surgery. We will recruit subjects with cervical spondylosis myelopathy meeting operation indications and scheduled for receiving cervical decompressive surgery, aged 18-84 years, have a history of hypertension or office systolic blood pressure ≥140 mmHg on initial screening, and willing to participate in the study and provide informed consent. Exclusion criteria includes a history of known secondary hypertension, visual analogue scale (VAS) score ≥4, and unable to comply with study due to severe psychosis. The change in systolic ABPs over the four times will be analyzed to observe the overall pattern of the blood pressure change in relation to the surgery, but the primary analysis will be the comparison of systolic ABP between the 2(nd) and 3(rd), 4(th) measurements (before and after the surgery). We will also calculate the regression-to-the-mean adjusted changes in systolic ABP as sensitivity analysis. Secondary endpoints are the changes in 24 h ABPM diastolic blood pressure, blood pressure control status, the use and dose adjustment of antihypertensive medication, and the incidence of operative complications. Primary outcome analyses will be carried out using analysis of covariance, as well as the first secondary endpoint. This study will inform us the important knowledge about cervical sympathetic nervous system (SNS) and blood pressure. Once confirmed, it may help to produce new method for control of hypertension, which is the leading cause of death in the world. The study is registered to Clinical Trials.gov (NCT02016768).

Bariatric surgery improves sexual function in obese individuals, although the extent to which sexual satisfaction is improved following surgery is unknown. The aims of this study were 1) to describe sexual satisfaction in severely/morbidly obese men and women candidates for bariatric surgery; 2) to assess the effects of bariatric surgery on sexual satisfaction at 12-months follow-up; and 3) to assess whether weight changes at follow-up following bariatric surgery are associated with changes in sexual satisfaction. We conducted a prospective observational study from February 2011 to June 2014. A total of 44 patients with severe/morbid obesity participated in the study. Sexual satisfaction was assessed (at baseline and 12-months follow-up) through the Index of Sexual Satisfaction (ISS) questionnaire. Of 44 patients who completed the ISS at baseline (mean age 40.3 [SD=9.4] years and BMI 46.9 [SD=6.2] kg/m 2 ), 17 were lost to follow-up. The baseline ISS total scores were 32.0 (SD=20.1) in women and 24.4 (SD=16.0) in men (P>0.05). The proportion of sexually satisfied men and women at baseline was 62.5% and 46.4%, respectively (P=0.360). At follow-up, sexual satisfaction improved significantly in women (average difference 13.7 units; P=0.032) but not in men (average difference 3.6 units; P=0.717). The percentage of women with sexual satisfaction problems was reduced by 33% at follow-up (P=0.038). A relatively large percentage of severely/morbidly obese women and men present clinically significant sexual satisfaction problems before undergoing bariatric surgery. Sexual satisfaction improves significantly 12 months following bariatric surgery, particularly in women. Copyright © 2017 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

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.
