The trend of surgical robotics is to follow the evolution of laparoscopy, which is now moving towards single-incision laparoscopic surgery. The main drawback of this approach is the limited maneuverability of the surgical tools. Promising solutions to improve the surgeon's dexterity are based on bimanual robots. However, since both robot arms are completely inserted into the patient's body, issues related to possible unwanted collisions with structures adjacent to the target organ may arise. This paper presents a simulator based on patient-specific data for the positioning and workspace evaluation of bimanual surgical robots in the pre-operative planning of single-incision laparoscopic surgery. The simulator, designed for the pre-operative planning of robotic laparoscopic interventions, was tested by five expert surgeons who evaluated its main functionalities and provided an overall rating for the system. The proposed system demonstrated good performance and usability, and was designed to integrate both present and future bimanual surgical robots.

Radical vaginal trachelectomy (VRT) is widely prescribed as a surgical procedure to treat early-stage cervical cancer while preserving fertility. However, the ideal obstetric standard of care for patients who have undergone VRT has not yet been established. Aim of this rerport is to analyze pregnancy outcomes and optimal obstetric management during pregnancy and delivery after vaginal radical trachelectomy (VRT). Forty-six cases of VRT from December 2003 to April 2013 in Peking Union Medical College Hospital were analyzed. The mean age of the patients at the time of VRT was 30.6 years and the mean follow-up time was 39.5 months. Of the 32 patients who attempted to conceive, 12 had 16 successful conceptions. There were two miscarriages and two elective abortions. One case of ectopic pregnancy and one case of second trimester loss occurred in this cohort. Ten cases reached the third trimester. Two patients delivered before 32 weeks, and four before 37 weeks. The total preterm delivery rate was 60%. All ten patients delivered by Cesarean section through a high transverse uterine incision. No uterine rupture or postpartum hemorrhage occurred. There is an increased occurrence of preterm delivery after VRT. Cesarean section after full term pregnancy through a high transverse incision should be considered as a suitable and safe procedure.

Most mortality attributable to surgical emergencies occurs in low- and middle-income countries. District hospitals, which serve as the first-level surgical facility in rural sub-Saharan Africa, are often challenged with limited surgical capacity. This study describes the presentation, management, and outcomes of non-obstetric surgical patients at district hospitals in Rwanda. This study included patients seeking non-obstetric surgical care at three district hospitals in rural Rwanda in 2013. Demographics, surgical conditions, patient care, and outcomes are described; operative and non-operative management were stratified by hospitals and differences assessed using Fisher's exact test. Of the 2660 patients who sought surgical care at the three hospitals, most were males (60.7 %). Many (42.6 %) were injured and 34.7 % of injuries were through road traffic crashes. Of presenting patients, 25.3 % had an operation, with patients presenting to Butaro District Hospital significantly more likely to receive surgery (57.0 %, p < 0.001). General practitioners performed nearly all operations at Kirehe and Rwinkwavu District Hospitals (98.0 and 100.0 %, respectively), but surgeons performed 90.6 % of the operations at Butaro District Hospital. For outcomes, 39.5 % of all patients were discharged without an operation, 21.1 % received surgery and were discharged, and 21.1 % were referred to tertiary facilities for surgical care. Significantly more patients in Butaro, the only site with a surgeon on staff and stronger surgical infrastructure, received surgery. Availing more surgeons who can address the most common surgical needs and improving supplies and equipment may improve outcomes at other districts. Surgical task sharing is recommended as a temporary solution.

Complex abdominal wall reconstruction is beset by postoperative complications. A recent meta-analysis comparing the use of closed-incision negative-pressure therapy to standard dressings found a statistically significant reduction in surgical-site infection. The use of closed-incision negative-pressure therapy is gaining acceptance in this population; however, the economic impact of this innovative dressing remains unknown. In this study, a cost-utility analysis was performed assessing closed-incision negative-pressure therapy and standard dressings following closure of abdominal incisions in high-risk patients. Cost-utility methodology involved reviewing literature related to closed-incision negative-pressure therapy in abdominal wall surgery, obtaining utility estimates to calculate quality-adjusted life-year scores for successful surgery and surgery complicated by surgical-site infection, summing costs using Medicare Current Procedural Terminology codes, and creating a decision tree illuminating the most cost-effective dressing strategy. One-way sensitivity analysis was performed to assess the robustness of the results. The aforementioned meta-analysis comparing closed-incision negative-pressure therapy to standard dressings included a subset of five studies assessing abdominal wall surgery in 829 patients (260 closed-incision negative-pressure therapy and 569 standard dressings). Decision tree analysis revealed an estimated savings of $1546.52 and a gain of 0.0024 quality-adjusted life-year with closed-incision negative-pressure therapy compared with standard dressings; therefore, closed-incision negative-pressure therapy is a dominant treatment strategy. One-way sensitivity analysis revealed that closed-incision negative-pressure therapy is a cost-effective option when the surgical-site infection rate is greater than 16.39 percent. The use of closed-incision negative-pressure therapy is cost-saving following closure of abdominal incisions in high-risk patients.

Sutures, staples and adhesive tapes are the traditional methods of wound closure, whilst tissue adhesives have entered clinical practice more recently. Closure of wounds with sutures enables meticulous closure, but they may show tissue reactivity and can require removal. Tissue adhesives offer the advantages of no risk of needlestick injury and no requirement to remove sutures later. Tissue adhesives have been used primarily in emergency rooms but this review looks at the use of tissue adhesives in the operating room where surgeons are increasingly using these for the closure of surgical skin incisions. To determine the relative effects of various tissue adhesives and conventional skin closure techniques on the healing of surgical wounds. For this update we searched the Cochrane Wounds Group Specialised Register (Searched 17/11/09); The Cochrane Central Register of Controlled Trials (CENTRAL) - The Cochrane Library Issue 4 2009; Ovid MEDLINE - 1950 to November Week 1 2009; Ovid EMBASE - 1980 to 2009 Week 46; EBSCO CINAHL - 1982 to 17 November 20098. No date or language restrictions were applied. Only randomised controlled clinical trials were eligible for inclusion. Screening of eligible studies and data extraction were conducted independently and in triplicate whilst assessment of the methodological quality of the trials was conducted independently and in duplicate. Results were expressed as random effects models using mean difference for continuous outcomes and relative risks with 95% confidence intervals for dichotomous outcomes. Heterogeneity was investigated including both clinical and methodological factors. This update identified an additional six trials resulting in a total of fourteen RCTs (1152 patients) which met the inclusion criteria. Sutures were significantly better than tissue adhesives for minimising dehiscence (10 trials). Sutures were also found to be significantly faster to use. For all other analyses of infection, patient and operator

There is an ongoing debate regarding the optimal instrument for scalp incisions: the scalpel or electrocautery. The argument generally focuses on improved healing after an incision made with a knife and decreased bleeding when using electrocautery. This study compares the use of scalpel and electrocautery in making coronal incisions for patients undergoing surgical correction of craniosynostosis. The outcome metric used is wound healing within 6 months after surgery. All patients presenting to the University of North Carolina Children's Hospital with craniosynostosis between July 1, 2007 and January 1, 2010 requiring a coronal incision for surgical correction were prospectively enrolled. In all of these patients, half of the coronal incision was made with knife; the other half, with needle tip cautery. Side of the incision was specified at the time of surgery in the operative report. Patients were excluded from the study if the instrument for incision was not specified or if only 1 modality was used for the entire incision. Sixty-eight patients underwent cranial vault reconstruction, of which 58 met inclusion criteria. Of the 58 matched pairs, 55 were analyzed statistically. The 3 excluded cases were those who had midline complications. There were 17 wound complications (15%): 8 in the knife group, 6 in the cautery group, and 3 at midline (with indeterminate side for the problem). We found no statistically significant difference in wound healing between incisions made with a knife or with electrocautery.

Hand-assisted laparoscopic donor nephrectomy is performed in many centers for donor nephrectomy. A midline incision for hand-assisted port placement is generally used but produces an unsightly scar. In this study, patients who had hand-assisted laparoscopic donor nephrectomy with low transverse incision were compared with those who received a midline incision. Our study group included patients who received hand-assisted laparoscopic donor nephrectomy from February 2012 to December 2014 at Korea University Anam Hospital. We retrospectively compared outcomes of these patients based on midline incision (45 patients) versus low transverse incision (17 patients). Risk factors, including age, sex, body mass index, creatinine level, glomerular filtration rate of allograft, side of graft kidney, number of renal arteries, duration of surgical procedure, and warm ischemic time, were compared between the midline and low transverse incision groups. When we compared the midline versus low transverse incision groups, duration of surgical procedure (P = .043), postoperative day 3 glomerular filtration rate (P = .017), and postoperative day 3 pain score (P = .049) were significantly higher in the low transverse incision group versus the midline incision group. Postoperative day 3 results for duration of hospitalization (P = .030) and pain score (P = .021) were also significantly higher in the low transverse versus midline incision groups when we focused on patients with left nephrectomy. Hand-assisted laparoscopic donor nephrectomy with low transverse incision is more painful and necessitates a longer hospital stay and longer surgical procedure. Despite these disadvantages, hand-assisted laparoscopic donor nephrectomy with low transverse incision can offer a better cosmetic outcome with no definitive differences regarding renal function compared with a midline incision. Surgeons should consider these aspects when deciding on the best method for donor nephrectomy.

The authors report 1,000 cases (357 cesarean sections, 230 hysterectomies for benign lesions, 157 conservative utero-adnexal procedures, 128 tubal plasties, 58 prolapse or incontinence procedures, 70 cancers) ,of laparotomies performed according to the technique described by Mouchel in 1980, i.e. strictly supra-pubic and transverse, from skin to peritoneum, including section of the rectus abdominis. This incision enables to perform in ideal technical conditions, with a minimal complication rate (3 hematomas, 2 incisional hernias for 1,000), and satisfactory esthetic results, almost all of the gynecological and obstetrical surgical procedures (90% of two among the authors' practice). The only contra-indications are, except for cases of previous median laparotomy, ovarian tumors. Neither the high risk of infection, nor obesity, extended hysterectomy, nor fetal distress, represent contra-indications, which is a definite advantage over the Pfannenstiel incision. As compared with the median incision which at some time offered similar results, the esthetics and mainly the strength of the abdominal wall are markedly superior.

2014-01-01

Background and Objectives: Single-incision laparoscopic surgery is gaining popularity among minimally invasive surgeons and is now being applied to a broad number of surgical procedures. Although this technique uses only 1 port, the diameter of the incision is larger than in standard laparoscopic surgery. The long-term incidence of port-site hernias after single-incision laparoscopic surgery has yet to be determined. Methods: All patients who underwent a single-incision laparoscopic surgical procedure from May 2008 through May 2009 were included in the study. Single-incision laparoscopic surgical operations were performed either by a multiport technique or with a 3-trocar single-incision laparoscopic surgery port. The patients were seen at 30 to 36 months' follow-up, at which time they were examined for any evidence of port-site incisional hernia. Patients found to have hernias on clinical examination underwent repairs with mesh. Results: A total of 211 patients met the criteria for inclusion in the study. The types of operations included were cholecystectomy, appendectomy, sleeve gastrectomy, gastric banding, Nissen fundoplication, colectomy, and gastrojejunostomy. We found a port-site hernia rate of 2.9% at 30 to 36 months' follow-up. Conclusion: Port-site incisional hernia after single-incision laparoscopic surgical procedures remains a major setback for patients. The true incidence remains largely unknown because most patients are asymptomatic and therefore do not seek surgical aid. PMID:24960483

Evaluate the capacity of government-run hospitals in Bangladesh to provide emergency and essential surgical, obstetric and anaesthetic services. Cross-sectional survey of 240 Bangladeshi Government healthcare facilities using the World Health Organisation Situational Analysis Tool to Assess Emergency and Essential Surgical Care (SAT). This tool evaluates the ability of a healthcare facility to provide basic surgical, obstetric and anaesthetic care based on 108 queries that detail the infrastructure and population demographics, human resources, surgical interventions and reason for referral, and available surgical equipment and supplies. For this survey, the Bangladeshi Ministry of Health sent the SAT to sub-district, district/general and teaching hospitals throughout the country in April 2013. Responses were received from 240 healthcare facilities (49.5% response rate): 218 sub-district and 22 district/general hospitals. At the sub-district level, caesarean section was offered by 55% of facilities, laparotomy by 7% and open fracture repair by 8%. At the district/general hospital level, 95% offered caesarean section, 86% offered laparotomy and 77% offered open fracture treatment. Availability of anaesthesia services, general equipment and supplies reflected this trend, where district/general hospitals were better equipped than sub-district hospitals, though equipment and infrastructure shortages persist. There has been overall impressive progress by the Bangladeshi Government in providing essential surgical services. Areas for improvement remain across all key areas, including infrastructure, human resources, surgical interventions offered and available equipment. Investment in surgical services offers a cost-effective opportunity to continue to improve the health of the Bangladeshi population and move the country towards universal healthcare coverage.

Intra-Operative Surgical Irrigation of the Surgical Incision: What Does the Future Hold-Saline, Antibiotic Agents, or Antiseptic Agents?

Intra-operative surgical site irrigation (lavage) is common practice in surgical procedures in general, with all disciplines advocating some form of irrigation before incision closure. This practice, however, has been neither standardized nor is there compelling evidence that it effectively reduces the risk of surgical site infection (SSI). This narrative review addresses the laboratory and clinical evidence that is available to support the practice of irrigation of the abdominal cavity and superficial/deep incisional tissues, using specific irrigation solutions at the end of an operative procedure to reduce the microbial burden at wound closure. Review of PubMed and OVID for pertinent, scientific, and clinical publications in the English language was performed. Incision irrigation was found to afford a three-fold benefit: First, to hydrate the bed; second, to assist in allowing better examination of the area immediately before closure; and finally, by removing superficial and deep incisional contamination and lowering the bioburden, expedite the healing process. The clinical practice of intra-operative peritoneal lavage is highly variable and is dependent solely on surgeon preference. By contrast, intra-operative irrigation after device-related procedures has become a standard of care for the prophylaxis of acute peri-prosthetic infection. The clinical evidence that supports the use of antibiotic irrigation is limited and based on retrospective analysis and few acceptable randomized controlled trials. The results of laboratory and animal studies using aqueous 0.05% chlorhexidine gluconate are favorable, suggesting that further studies are justified to determine its clinical efficacy. The adoption of appropriate and standardized intra-operative irrigation practices into peri-operative care bundles, which include other evidence-based strategies (weight-based antimicrobial prophylaxis, antimicrobial sutures, maintenance of normothermia, and glycemic control), offers

We performed a retrospective review of non-overweight (body mass index ≤ 25 kg/m2) patients scheduled to undergo a curative resection of locally advanced colon cancer via a transverse mini-incision (n = 62) or a longitudinal mini-incision (skin incision ≤7 cm, n = 62), with the latter group of patients randomly selected as historical controls matched with the former group according to tumor location. Extension of the transverse mini-incision wound was necessary in 3 patients (5%). Both groups were largely equivalent in terms of demographic, clinicopathological, and surgical factors and frequency of postoperative complications. Postoperative analgesic was significantly less (P = 0.04) and postoperative length of the hospital stay was significantly shorter (P < 0.01) in the transverse mini-incision group. Concerning a mini-incision approach for locally advanced colonic cancer, a transverse incision seems to be advantageous with regard to minimal invasiveness and early recovery compared with a longitudinal incision.

Management of obstetric hemorrhage.

Shevell, Tracy; Malone, Fergal D

A reluctance to proceed with hysterectomy for obstetric hemorrhage may be a more likely cause of preventable death in obstetrics than a lack of surgical or medical skills. Every obstetric unit should have protocols available to deal with hemorrhage and, in addition, have specific guidelines for patients who object to blood transfusions for various reasons. Risk factors for hemorrhage should be identified antenatally, using all possible imaging modalities available, and utilizing multidisciplinary resources whenever possible. Novel strategies for prenatal diagnosis of abnormal placentation include advanced sonography and magnetic resonance imaging. Placement and utilization of arterial catheters for uterine artery embolization is becoming more widespread and new surgical technology such as the argon beam coagulator seems promising. When intra or postpartum hemorrhage is encountered, a familiar protocol for dealing with blood loss should be triggered. Timely hysterectomy should be performed for signs of refractory bleeding. Application of medical and surgical principles combined with recent technologic advances will help the obstetrician avoid disastrous outcomes for both mother and fetus.

The treatment of post-surgical wound complications, such as surgical site infections and surgical wound dehiscence, generates a significant burden for patients and healthcare systems. The effectiveness of negative pressure wound therapy has been under investigation but to date no systematic review has been published in relation to its effectiveness in the prevention of surgical wound complications. To identify the effectiveness of negative pressure wound therapy in the prevention of post-surgical wound complications in adults with a closed surgical incision compared to standard surgical dressings. Male and female adults who have had negative pressure wound therapy applied to their surgical incision following a procedure in one of the following areas: trauma, cardiothoracic, orthopedic, abdominal, or vascular surgery.The intervention of interest was the use of negative pressure wound therapy directly over an incision following a surgical procedure; the comparator was standard surgical dressings.Both experimental and epidemiological study designs, including randomized controlled trials, pseudo-randomized trials, quasi-experimental studies, before and after studies, prospective and retrospective cohort studies, case control studies, and analytical cross sectional studies were sought.The primary outcome was the occurrence of post-surgical wound infection or dehiscence as measured by the following: surgical site infections - superficial and deep; surgical wound dehiscence; wound pain; wound seroma; wound hematoma. Published and unpublished studies in English from 1990 to 2013 were identified by searching a variety of electronic databases. Reference lists of all papers selected for retrieval were then searched for additional studies. Papers selected for retrieval were assessed by two independent reviewers for methodological validity prior to inclusion in the review using standardized critical appraisal instruments from the Joanna Briggs Institute Meta-Analysis of

To assess the surgically induced corneal astigmatism (SIA) introduced by femtosecond laser-assisted clear corneal incisions (CCIs) for cataract extraction and to compare it with the SIA of manually created CCIs. Bascom Palmer Eye Institute, Miller School of Medicine, Miami, Florida, USA. Prospective nonrandomized comparative case series. Eyes received femtosecond laser-assisted CCIs (Group 1) or manual CCIs (Group 2). The surgical plan included 1 primary and 1 secondary port; the sites of the incisions were the same in both groups and were diametrically opposed between the right eye and left eye. The SIA was assessed using the preoperative and 1-month postoperative keratometric values obtained from corneal topography examinations. This study included 72 eyes of 68 patients with a mean age of 69.0 years ± 9.87 (SD) (range 36 to 90 years). Thirty-six eyes received femtosecond laser-assisted CCIs (Group 1) and 36 received manual CCIs (Group 2). The mean preoperative topographic corneal astigmatism was -1.19 ± 0.68 diopters (D) (range 0 to 2.50 D) and -0.92 ± 0.63 D (range 0.10 to 2.45 D) for Group 1 and Group 2, respectively, whereas, 1 month after cataract surgery, it was -1.16 ± 0.63 D (range 0.20 to 2.57 D) and -0.95 ± 0.64 D (range 0.21 to 2.37 D), respectively. Multivariate vector analysis revealed no statistically significant difference between the 2 groups for preoperative astigmatism, postoperative astigmatism, and SIA (P > .05 for all comparisons between Group 1 and Group 2). Femtosecond laser-assisted and manual corneal incisions for cataract surgery did not appear to significantly alter corneal astigmatism, whereas they showed comparable SIA. Drs.

Iatrogenic injury to the infrapatellar branch of the saphenous nerve is a common complication of surgical approaches to the anteromedial side of the knee. A detailed description of the relative anatomic course of the nerve is important to define clinical guidelines and minimize iatrogenic damage during anterior knee surgery. In twenty embalmed knees, the infrapatellar branch of the saphenous nerve was dissected. With use of a computer-assisted surgical anatomy mapping tool, safe and risk zones, as well as the location-dependent direction of the nerve, were calculated. The location of the infrapatellar branch of the saphenous nerve is highly variable, and no definite safe zone could be identified. The infrapatellar branch runs in neither a purely horizontal nor a vertical course. The course of the branch is location-dependent. Medially, it runs a nearly vertical course; medial to the patellar tendon, it has a -45° distal-lateral course; and on the patella and patellar tendon, it runs a close to horizontal-lateral course. Three low risk zones for iatrogenic nerve injury were identified: one is on the medial side of the knee, at the level of the tibial tuberosity, where a -45° oblique incision is least prone to damage the nerves, and two zones are located medial to the patellar apex (cranial and caudal), where close to horizontal incisions are least prone to damage the nerves. The infrapatellar branch of the saphenous nerve is at risk for iatrogenic damage in anteromedial knee surgery, especially when longitudinal incisions are made. There are three low risk zones for a safer anterior approach to the knee. The direction of the infrapatellar branch of the saphenous nerve is location-dependent. To minimize iatrogenic damage to the nerve, the direction of incisions should be parallel to the direction of the nerve when technically possible. These findings suggest that iatrogenic damage of the infrapatellar branch of the saphenous nerve can be minimized in anteromedial

According to the literature, incisional closure complications may range from postoperative surgical site infections, representing 17-22% of health care-associated infections, surgical wound dehiscence and formation of haematomas or seromas, and can lead to delayed or impaired incision healing. These kinds of situations are more common when wounds are closed under tension or in specific patient morbidities. Obesity, in particular, is associated with an impaired blood flow to tissues, predisposing the patient to increased risk of wound complications by various mechanisms. Incisional complications can become relevant economic burdens for health care systems because of an increase in the average length of hospital stay and readmissions, and additional medical and surgical procedures. Thus, a preventive therapy may have a critical role in the management of healing. Negative pressure wound therapy (NPWT) technology as delivered by Prevena™ Customizable™ (Kinetic Concepts Inc., San Antonio, TX) has recently been the focus of a new investigation, as a prophylactic measure to prevent complications via immediate postoperative application in high-risk, clean, closed surgical incisions. The authors present a 62-year-old class II obese female, who underwent bilateral inguinal dermolipectomy. Prophylactic NPWT as delivered by Prevena™ was performed successfully over surgical incisions. Cosmetic and therapeutic results are shown. © 2014 The Authors.

Background and Objective As a result of wound healing the original tissue is replaced by dysfunctional scar tissue. Reduced tissue damage during surgical procedures beneficially affects the size of the resulting scar and overall healing time. Thus the choice of a particular surgical instrument can have a significant influence on the postoperative wound healing. To overcome these problems of wound healing we applied a novel picosecond infrared laser (PIRL) system to surgical incisions. Previous studies indicated that negligible thermal, acoustic, or ionization stress effects to the surrounding tissue results in a superior wound healing. Study Design/Materials and Methods Using the PIRL system as a surgical scalpel, we performed a prospective wound healing study on rat skin and assessed its final impact on scar formation compared to the electrosurgical device and cold steel. As for the incisions, 6 full‐thickness, 1‐cm long‐linear skin wounds were created on the dorsum of four rats using the PIRL, an electrosurgical device, and a conventional surgical scalpel, respectively. Rats were euthanized after 21 days of wound healing. The thickness of the subepithelial fibrosis, the depth and the transverse section of the total scar area of each wound were analyzed histologically. Results After 21 days of wound healing the incisions made by PIRL showed minor scar tissue formation as compared to the electrosurgical device and the scalpel. Highly significant differences (P < 0.001) were noted by comparing the electrosurgical device with PIRL and scalpel. The transverse section of the scar area also showed significant differences (P = 0.043) when comparing PIRL (mean: 141.46 mm2; 95%CI: 105.8–189.0 mm2) with scalpel incisions (mean: 206.82 mm2; 95%CI: 154.8–276.32 mm2). The subepithelial width of the scars that resulted from using the scalpel were 1.3 times larger than those obtained by using the PIRL (95%CI: 1.0–1.6) though the difference was not

To evaluate the effectiveness of a preoperative skills curriculum, and to assess and document competence in associated Obstetrics and Gynecology Level 1 Milestones. The Decision to Incision curriculum was developed by a team of medical educators with the goal of teaching and evaluating 5 skills pertinent to Milestone 1: Preoperative consent, patient positioning, Foley catheter placement, surgical scrub, and preoperative time-out. Competence, overall skill performance, and knowledge were assessed by evaluator rating using checklists before and after the educational intervention. Differences between preintervention and postintervention skills performance and competence were assessed using Wilcoxon rank test and Fisher exact test, respectively. Clinical Simulation Center at an academic medical center. Overall, 29 fourth year medical students matriculating into Obstetrics and Gynecology residencies. The proportion of participants meeting Milestone competence significantly increased in all 5 skills, with competence achieved in 95.6% (95% CI: 92.1-99.0) of posttest skills assessments. Median overall performance also significantly improved for all 5 skills, with 83.6% (95% CI: 77.3-89.9) earning scores of 4 out of 5 or greater on the posttest. For knowledge testing, the proportion of correct responses significantly increased for both topics evaluated, from 45.2% to 99.7% (p < 0.0001) for positioning and from 32.8% to 83.1% (p < 0.0001) for time-out. The decision to incision curriculum significantly improved preoperative skills, including skills that may be required on day 1 of residency. This curriculum also facilitated achievement and documentation of competence in multiple Milestones. Copyright © 2016 Association of Program Directors in Surgery. Published by Elsevier Inc.

The article addresses issues of comparative characterization of deliveries involving surgery and impact thereof on the health of the mother and her child. Risk factors are identified that the mother and her child run in sectio cesarea, in application of obstetrical forceps, and in vacuum-extraction of the fetus. Cesarean section was found out to be the most acceptable mode of delivery in origination of organic and functional nervous system involvement in children but the most ill-chosen and unpropitious one in the mother, especially so in those groups at risk for bleeding, septic complications, and genital endometriosis. Among those surgical methods of delivery being the least traumatic to the mother are obstetrical forceps and vacuum-extraction of the fetus.

In low-income and middle-income countries, surgical epidemiology is largely undefined at the population level, with operative logs and hospital records serving as a proxy. This study assesses the distribution of surgical conditions that contribute the largest burden of surgical disease in Burera District, in northern Rwanda. We hypothesise that our results would yield higher rates of surgical disease than current estimates (from 2006) for similar low-income countries, which are 295 per 100 000 people. In March and May, 2012, we performed a cross-sectional study in Burera District, randomly sampling 30 villages with probability proportionate to size and randomly sampling 23 households within the selected villages. Six Rwandan surgical postgraduates and physicians conducted physical examinations on all eligible participants in sampled households. Participants were assessed for injuries or wounds, hernias, hydroceles, breast mass, neck mass, obstetric fistula, undescended testes, hypospadias, hydrocephalus, cleft lip or palate, and club foot. Ethical approval was obtained from Boston Children's Hospital (Boston, MA, USA) and the Rwandan National Ethics Committee (Kigali, Rwanda). Informed consent was obtained from all participants. Of the 2165 examined individuals, the overall prevalence of any surgical condition was 12% (95% CI 9·2-14·9) or 12 009 per 100 000 people. Injuries or wounds accounted for 55% of the prevalence and hernias or hydroceles accounted for 40%, followed by neck mass (4·2%), undescended testes (1·9%), breast mass (1·2%), club foot (1%), hypospadias (0·6%), hydrocephalus (0·6%), cleft lip or palate (0%), and obstetric fistula (0%). When comparing study participant characteristics, no statistical difference in overall prevalence was noted when examining sex, wealth, education, and travel time to the nearest hospital. Total rates of surgically treatable disease yielded a statistically significant difference compared with current

Parallel pocket incision: Less invasive surgical intervention for the treatment of intractable pressure ulcer with wound edge undermining.

Yamamoto, Takumi; Yoshimatsu, Hidehiko; Hayashi, Akitatsu; Koshima, Isao

The treatment of deep pressure ulcer with a wide wound edge undermining (pocket) is challenging, especially when conservative treatments are ineffective. As most patients with a pressure ulcer suffer from systemic comorbidities, invasive surgery cannot be performed on all patients, and less invasive treatment is required. Less invasive surgical intervention to a deep pressure ulcer, parallel pocket incision (PPI), was performed on 10 patients with intractable pressure ulcers with a pocket formation. In PPI procedures, two parallel skin incisions were made to open up the deepest fold of the pocket and to preserve the skin overlying the pocket lesion; through the created incisions, the necrotic tissues around the deepest fold of the undermining could be easily removed, which facilitated spontaneous wound healing. Postoperative results and complications were evaluated. All PPI procedures were safely performed under local infiltration anesthesia without major postoperative complication; minor bleeding was seen intraoperatively in three patients, which could be easily controlled with electric cautery coagulation. Nine of 10 ulcers were cured after PPI, and one could not be followed up due to the patient's death non-related to the pressure ulcer. For the nine cured patients, the average time for cure was 14.9 weeks, and no recurrence was observed at postoperative 6 months. PPI is a simple, technically easy, and less invasive surgical intervention to an intractable pressure ulcer with a pocket, which can be safely performed under local infiltration anesthesia even on a patient with severe systemic comorbidities.

Background. In this retrospective study, we aimed to compare the results of two surgical techniques, conventional and transverse mini-incision. Materials and Methods. 95 patients were operated between 2011 and 2012 in Bitlis State Hospital. 50 patients were operated with conventional technique and 45 of them were operated with minimal transverse incision. Postoperative complications, incision site problems, and the time of starting to use their hands in daily activities were noted. Results. 95 patients were included in the study. The mean age was 48. 87 of them were female and 8 were male. There was no problem of incision site in both of the two surgical techniques. Only in one patient, anesthesia developed in minimal incision technique. The time of starting to use their hands in daily activities was 22,2 days and 17 days in conventional and minimal incision technique, respectively. Conclusion. Two surgical techniques did not show superiority to each other in terms of postoperative complications and incision site problems except the time of starting to use their hands in daily activities.

Borrego, Leopoldo; Hernández, Noelia; Hernández, Zaida; Peñate, Yeray

Povidone-iodine solution is an antiseptic that is used worldwide as surgical paint and is considered to have a low irritant potential. Post-surgical severe irritant dermatitis has been described after the misuse of this antiseptic in the surgical setting. Between January 2011 and June 2013, 27 consecutive patients with post-surgical contact dermatitis localized outside of the surgical incision area were evaluated. Thirteen patients were also available for patch testing. All patients developed dermatitis the day after the surgical procedure. Povidone-iodine solution was the only liquid in contact with the skin of our patients. Most typical lesions were distributed in a double lumbar parallel pattern, but they were also found in a random pattern or in areas where a protective pad or an occlusive medical device was glued to the skin. The patch test results with povidone-iodine were negative. Povidone-iodine-induced post-surgical dermatitis may be a severe complication after prolonged surgical procedures. As stated in the literature and based on the observation that povidone-iodine-induced contact irritant dermatitis occurred in areas of pooling or occlusion, we speculate that povidone-iodine together with occlusion were the causes of the dermatitis epidemic that occurred in our surgical setting. Povidone-iodine dermatitis is a problem that is easily preventable through the implementation of minimal routine changes to adequately dry the solution in contact with the skin. © 2015 The International Society of Dermatology.

Surgical scars on the palmar surface of the hand may lead to functional and also aesthetic and psychological consequences. The objective of this study was to introduce a new incision technique for periarterial sympathectomy of the hand and to compare the results of the new two-step incision technique with those of a Koman incision by using an objective questionnaire. A total of 40 patients (17 men and 23 women) with intractable Raynaud's disease or syndrome underwent surgery in our hospital, conducted by a single surgeon, between January 2008 and January 2013. Patients who had undergone extended sympathectomy or vessel graft were excluded. Clinical evaluation of postoperative scars was performed in both groups one year after surgery using the patient and observer scar assessment scale (POSAS) and the Wake Forest University rating scale. The total patient score was 8.59 (range, 6-15) in the two-step incision group and 9.62 (range, 7-18) in the Koman incision group. A significant difference was found between the groups in the total PS score (P-value=0.034) but not in the total observer score. Our analysis found no significant difference in preoperative and postoperative Wake Forest University rating scale scores between the two-step and Koman incision groups. The time required for recovery prior to returning to work after surgery was shorter in the two-step incision group, with a mean of 29.48 days in the two-step incision group and 34.15 days in the Koman incision group (P=0.03). Compared to the Koman incision, the new two-step incision technique provides better aesthetic results, similar symptom improvement, and a reduction in the recovery time required before returning to work. Furthermore, this incision allows the surgeon to access a wide surgical field and a sufficient exposure of anatomical structures.

Small incision guarded hydroaspiration of iris lesions.

Singh, Arun D

2017-11-01

To describe the technique and results of a minimally invasive surgical technique for resection of small iris lesions. Consecutive case series of 22 patients with localised, small iris lesions that were resected using the described surgical technique that composed of multiple, small corneal incisions created to allow for internal iris resection with 23-gauge horizontal vitrectomy scissors, followed by guarded tumour aspiration through a clear plastic tubing (diameter 3.5 mm) primed with viscoelastic agent. The mean largest basal diameter was 3.0 mm (range 1.5-5.0 mm; median 3.0 mm) and mean thickness was 1.3 mm (range 0.5-2.5 mm; median 1.0 mm). Use of multiple (2-4) small corneal incisions (range 2.0-3.0 mm; mean 2.8 mm) allowed reduced postoperative morbidity (significant hyphema (0%), hypotony (0%), wound leak (0%), >2 line change in best corrected visual acuity at postoperative 1 week (4.5%) and mean corneal astigmatism of 1.0 D (range 0.14-2.99 D; median 0.8 D) at postoperative 4-12 weeks. The tumour could be resected with clear surgical margins in all neoplastic cases (benign (2), borderline (1) and malignant (16)). Local recurrence or metastases were not observed in any melanoma case over a mean follow-up of 33.0 months (range 1.0-90.0 months; median 33.5 months). Small incision guarded hydroaspiration is a minimally invasive surgical technique for resection of select small iris lesions. Use of multiple small corneal incisions avoids morbidity associated with a single large corneoscleral incision, and use of guarded aspiration may eliminate the risk of wound contamination by the malignant tumour.

Surgical Informed Consent (SIC) has long been recognized as an important component of modern medicine. The ultimate goals of SIC are to improve clients' understanding of the intended procedure, increase client satisfaction, maintain trust between clients and health providers, and ultimately minimize litigation issues related to surgical procedures. The purpose of the current study is to assess the comprehensiveness of the SIC process for women undergoing obstetric and gynecologic surgeries. A hospital-based cross-sectional study was undertaken at Hawassa University Comprehensive Specialized Hospital (HUCSH) in November and December, 2016. A total of 230 women who underwent obstetric and/or gynecologic surgeries were interviewed immediately after their hospital discharge to assess their experience of the SIC process. Thirteen components of SIC were used based on international recommendations, including the Royal College of Surgeon's standards of informed consent practices for surgical procedures. Descriptive summaries are presented in tables and figures. Forty percent of respondents were aged between 25 and 29 years. Nearly a quarter (22.6%) had no formal education. More than half (54.3%) of respondents had undergone an emergency surgical procedure. Only 18.4% of respondents reported that the surgeon performing the operation had offered SIC, while 36.6% of respondents could not recall who had offered SIC. All except one respondent provided written consent to undergo a surgical procedure. However, 8.3% of respondents received SIC service while already on the operation table for their procedure. Only 73.9% of respondents were informed about the availability (or lack thereof) of alternative treatment options. Additionally, a majority of respondents were not informed about the type of anesthesia to be used (88.3%) and related complications (87.4%). Only 54.2% of respondents reported that they had been offered at least six of the 13 SIC components used by the

The aim of this study is to describe the surgical technique, and assess the complications and middle-term results of the Contasure Needleless (Neomedic International), a single incision TOT sling for the surgical treatment of stress urinary incontinence. The main concept of this device is that it is not a mini-sling, it has 138% more surface area. We are analyzing the results of a minimally invasive solution that is a TOT like sling with the same known benefits of a TOT and the advantages of a single incision technique. The surface area to support the urethra of the Needleless is very similar to the surface area of the TOT. (16% less surface area of tissue ingrowths) It is 100% macroporous polypropylene without any additional material. 120 patients were evaluated retrospectively. They were all treated of SUI with the Contasure Needleless.Female patients were evaluated under clinical study protocol consisting in cough test, urodynamic and Quality Of Life questionnaire, before and after the procedure. patients with genuine SUI and patients with SUI plus concomitant procedures as prolapse. patients with ISD and or neurogenic incontinence. Anesthesia used: general (30%) or epidural (70%), patients with associated pathology. The 114 mm long and tension-free mesh was placed beneath the midurethra. The central part is 12 mm wide. The sling can be repositioned during surgery due to the 22 mm wide T-Pocket Positioning System located at the 2 edges. These pockets fixed the sling to the surrounding tissue in order to have the proper tissue in growth and anchoring. A 20mm sub urethral incision was made to dissect the paraurethral spaces only up to the ischiopubic ramus. A surgical forceps with the T-pocket folded was inserted into the dissected spaces and penetrates at the contra lateral side, like the standard transobturator technique. The forceps was introduced until the fascia of the Internal Obturator muscle was perforated. Then the forceps is opened to extend the pocket

Changes in collagen in the wound during the healing process of guinea pig skin following surgical incisions and LTW was evaluated using in vivo, using Raman spectroscopy. Raman spectroscopy provided information regarding the internal structure of the proteins. After the incisions were closed either by suturing or by LTW the ratio of the Raman peaks of the amide III (1247 cm-1) band to a peak at 1326 cm-1 used to evaluate the progression of collagen deposition. Histopathology was used as the gold standard. LTW skin demonstrated better healing than sutured skin, exhibiting minimal hyperkeratosis, minimal collagen deposition, near-normal surface contour, and minimal loss of dermal appendages. This work is important to plastic surgery.

To compare the morphologic features and surgically induced astigmatism (SIA) between laser and manual clear corneal incisions (CCIs) after femtosecond laser-assisted cataract surgery. Eye Center, 2nd Affiliated Hospital, Medical College of Zhejiang University, Hangzhou, China. Prospective case series. Patients had femtosecond laser-assisted cataract surgery with a CCI created with the laser or manually after random allocation. The corrected distance visual acuity, corneal topography, and anterior segment optical coherence tomography were assessed at the 1-day, 1-week, 1-month, and 3-month follow-ups. The laser CCI group comprised 45 eyes and the manual CCI group, 48 eyes. The SIA was significantly lower in the manual CCI group than the laser CCI group at all visits (P < .05). At the 1-day and 1-week follow-ups, the mean CCI thickness was significantly smaller in the manual CCI group (P < .05). In the laser CCI group, the perpendicular linear distance between the external wound opening and the corneal vertex central line was statistically shorter than in the manual CCI group (P < .05). At 3 months, the SIA was correlated with the perpendicular linear distance with a Pearson correlation coefficient of -0.341 (P = .001). Femtosecond laser-created CCIs for cataract surgery caused more SIA than manually created CCIs, which could have resulted from inaccurate or uncertain corneal incision positioning of the femtosecond machine. Manual creation of CCIs is recommended in femtosecond laser-assisted cataract surgery until the locating system for the femtosecond laser incision is updated. Copyright © 2017 ASCRS and ESCRS.

To compare the anatomic and refractive outcomes in eyes having phacoemulsification with 1 of 3 clear corneal incision (CCI) closure methods. Ambulatory surgical center, Makati, Philippines. Prospective randomized clinical trial. Patients having phacoemulsification cataract surgery had wound closure using no additional treatment (control), a single 10-0 nylon suture, or a liquid adhesive ocular bandage (Ocuseal). The main outcome measures were wound-edge closure rates, surgically induced astigmatism (SIA), foreign-body sensation, and intraocular pressure (IOP) 1, 3, 5, 7, and 14 days postoperatively. The study evaluated 90 eyes. There was a significant improvement in wound-edge closure rates in the suture group and the ocular bandage group compared with the control group (P<.001). A significant increase in SIA occurred in the sutured group but not in the control or ocular bandage groups (P<.001). The ocular bandage group had significantly less foreign-body sensation than the control and suture groups (P<.001). There were no significant differences in IOP between the groups (P=.515). The liquid adhesive ocular bandage resulted in improved wound-edge closure, reduced SIA, and diminished foreign-body sensation. Suturing was associated with improved wound-edge closure but increased SIA and foreign-body sensation. Unsutured incisions led to delayed wound-edge closure and increased foreign-body sensation.

Sutures (stitches), staples and adhesive tapes have been used for many years as methods of wound closure, but tissue adhesives have entered clinical practice more recently. Closure of wounds with sutures enables the closure to be meticulous, but the sutures may show tissue reactivity and can require removal. Tissue adhesives offer the advantages of an absence of risk of needlestick injury and no requirement to remove sutures later. Initially, tissue adhesives were used primarily in emergency room settings, but this review looks at the use of tissue adhesives in the operating room/theatre where surgeons are using them increasingly for the closure of surgical skin incisions. To determine the effects of various tissue adhesives compared with conventional skin closure techniques for the closure of surgical wounds. In March 2014 for this second update we searched the Cochrane Wounds Group Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE and EBSCO CINAHL. We did not restrict the search and study selection with respect to language, date of publication or study setting. Only randomised controlled trials were eligible for inclusion. We conducted screening of eligible studies, data extraction and risk of bias assessment independently and in duplicate. We expressed results as random-effects models using mean difference for continuous outcomes and risk ratios (RR) with 95% confidence intervals (CI) for dichotomous outcomes. We investigated heterogeneity, including both clinical and methodological factors. This second update of the review identified 19 additional eligible trials resulting in a total of 33 studies (2793 participants) that met the inclusion criteria. There was low quality evidence that sutures were significantly better than tissue adhesives for reducing the risk of wound breakdown (dehiscence; RR 3.35; 95% CI 1.53 to 7

To study the influence of high-frequency electric surgical knives on healing of abdominal incision. Two hundred and forty white rats were divided into 10(0), 10(2), 10(5), and 10(8) groups and rat models of abdominal operation were induced by using electric surgical knives and common lancets respectively. Then they were respectively given hypodermic injections of normal saline and 0.2 mL quantitative mixture of Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa at a concentration of 10(2), 10(5) and 10(8). On the basis of the animal experiment, 220 patients undergoing abdominal operations (above type II) were randomly allocated into one of following three groups: electric knife (EK, 93 cases), electro-coagulation (EC, 55 cases) and control (72 cases). High-frequency electric surgical knives were used to dissect abdominal tissues and electro-coagulation for hemostasis in EK group. Common lancets and electro-coagulation were applied in EC group. Common lancets and tying silk suture were used in the controls. In all the groups except group 10(0), infection rate of incisional wounds made by electric surgical knives were remarkably higher than that with common lancets. Furthermore, there were significant differences in groups 10(2), 10(5), and 10(8) (P<0.05), but not in group 10(0) (P>0.05) between EK and EC groups. Clinical studies showed a delayed wound healing in 16 cases (17.20%) in EK, 11 cases (16.36%) in EC and 2 cases (2.86%) in the control groups. A significant difference between EK and the control groups (chi2 = 8.57, P<0.01), and between EC and the control groups (chi2 = 5.66, P<0.05) was observed, but not between EK and EC (chi2 = 0.017, P>0.05). High-frequency electric knives may remarkably delay abdominal incision healing. Its application should be minimized so as to reduce the possibility of postoperative complications.

Changes in gynaecological practice have resulted in a significant reduction in surgical exposure for trainees. We have attempted to assess surgical experience among obstetric and gynaecology SpR's in Ireland using an anonymous on-line questionnaire. Trainees were asked to assess their own ability to perform a variety of general gynaecological procedures. There was a 97% response rate (29/33 trainees). There were 11 trainees who were in the final or penultimate year of the scheme. This group were analysed separately to assess competency rates in those approaching the end of the scheme. They were subdivided in to those who have completed one year in a general hospital doing pure gynaecology and those who have not. Approximately half of this group (6/11) had completed a pure gynaecology year. All of these trainees deemed themselves competent to perform all general gynaecological procedures listed, with the exception of trans-urethral tape procedures, for which 3/6 reported the requirement of direct supervision. Only 2/6 deemed themselves competent to perform a total laparoscopic hysterectomy. Year 4/5 trainees who had not completed a pure gynaecology year displayed significantly lower competency rates for most of the procedures. With the current changes in gynaecological practice, these results highlight the importance of dedicated gynaecological surgical training.

Secure closure of the tracheal incision after natural orifice transluminal endoscopic surgery with a surgical sealant (CoSeal).

2011-09-01

To evaluate the effectiveness of surgical sealant (CoSeal) in sealing the tracheal assess sites after transtracheal thoracoscopy. Two dogs underwent transtracheal thoracic exploration and pericardial window creation. The thoracic cavity was approached with flexible bronchoscope through a 9-mm tracheal incision. The pericardial window was performed with a needle knife via the working channel of the bronchoscope, and the tracheal assess site was closed with CoSeal using a rubber catheter. The integrity of tracheal healing was evaluated under positive pressure ventilation. Transtracheal creation of pericardial window and closure of tracheal incision with CoSeal was successfully performed in both dogs. There was no evidence of air leaks from the chest tube during positive pressure ventilation. Autopsy revealed no injury to the mediastinum and intrathoracic structure. Endoscopic closure of tracheal access site of NOTES with CoSeal appears to be a feasible technique.

To describe the procedure, efficacy, and utility of single-incision laparoscopic-assisted stoma creation (SILStoma) for transverse colostomy. Using single-incision laparoscopic surgery, we developed a standardized technique for SILStoma. Twelve consecutive patients underwent SILStoma for transverse colostomy at Osaka Medical Center for Cancer and Cardiovascular Diseases from April 2013 to March 2016. A single, intended stoma site was created with a 2.5-3.5 cm skin incision for primary access to the intra-abdominal space, and it functioned as the main port through which multi-trocars were placed. Clinical and operative factors and postoperative outcomes were evaluated. Patient demographics, including age, gender, body mass index, and surgical indications for intestinal diversion were evaluated. SILStoma was performed in nine cases without the requirement of additional ports. In the remaining three cases, 1-2 additional 5-mm ports were required for mobilization of the transverse colon and safe dissection of abdominal adhesions. No cases required conversion to open surgery. In all cases, SILStoma was completed at the initial stoma site marked preoperatively. No intraoperative or postoperative complications greater than Grade II (the Clavien-Dindo classification) were reported in the complication survey. Surgical site infection at stoma sites was observed in four cases; however, surgical interventions were not required and all infections were cured completely. In all cases, the resumption of bowel movements was observed between postoperative days 1 and 2. SILStoma for transverse loop colostomy represents a feasible surgical procedure that allows the creation of a stoma at the preoperatively marked site without any additional large skin incisions.

To present the feasibility of no skin incision orchiopexy in children with concomitant hypospadias and undescended testis (UDT) by a single subcoronal incision technique. To introduce the creation of subdartos muscle scrotal pouch with no scrotal skin incision. From one thousand and twenty-one children with hypospadias, 61 patients presented with concomitant palpable UDT and hypospadias. In group I (N = 34) single subcoronal incision with no scrotal skin incision was applied. In group II (N = 27), multi-incision technique was applied for classical orchiopexy and hypospadias surgery. For hypospadias reconstruction, all patients had classical subcoronal and para urethral plate incision with penile skin degloving according to the location of urethral meatus. Early and late complications, surgical time, hospital stay, and cosmetic results were recorded. Children with unilateral UDT and hypospadias had one incision in group I and three skin incisions in group II. Patients with bilateral UDT had one incision in group I and five skin incisions in group II. The operation time was significantly shorter in group I (93 ± 11 min) compared with group II (138 ± 17 min) (P = 0.03). Both groups were operated as day care basis; however, the hospital stay was slightly longer in group II (group I = 12 ± 2 h, vs group II = 16 ± 3 h) (P = 0.07). All testes were satisfactorily positioned into the bottom of the scrotum without development of any testicular atrophy. Single subcoronal penile skin incision is a feasible, safe, and cosmetically satisfactory technique in patients with hypospadias and concomitant UDT. Reduced postoperative pain, better objective cosmetic results, shorter operative time and comfortable post-operative period are the most significant advantages of this approach.

Transumbilical laparoscopic-assisted appendectomy (TULA) is a single incision technique that exteriorizes the appendix through the umbilicus. The aim of this study was to compare the surgical outcomes of TULA with SILA in pediatric appendicitis. A retrospective review of medical records between April 2011 and April 2015 identified 250 pediatric patients who underwent single incision laparoscopic appendectomy. Of these, 137 patients underwent TULA and 113 patients underwent SILA. Measured outcomes included patients' demographics, clinical characteristics, operative time, length of stay, pain, and postoperative complications. TULA group had a shorter operative time than SILA group (28.93 vs. 49.19min, p<0.001). The use of rescue analgesics was more frequent in the SILA group (six cases (6.5%) vs. 19 cases (23.4%), p<0.001). There was no significant difference in cosmetic outcome between the two groups. However, TULA was associated with a lower complication rate (2/137, 1.5%) than SILA (11/113, 9.8%) (p=0.0035). In multiple logistic regression analysis, TULA was significantly associated with a lower complication rate (p=0.049). TULA is preferable to SILA for treating pediatric acute appendicitis because it is technically easier, results in better surgical outcomes, and provides the same excellent cosmetic results.

To compare incision integrity and clinical outcomes of 2 microcoaxial phacoemulsification systems. Iladevi Cataract & IOL Research Centre, Ahmedabad, India. Prospective randomized clinical trial. Eyes were randomized to have phacoemulsification using a 1.8 mm clear corneal incision (CCI) system (Group 1, Stellaris system) or a 2.2 mm CCI system (Group 2, Intrepid Infiniti system). Incision enlargement at end of surgery was measured. At the conclusion of surgery, trypan blue was applied over the conjunctival surface, anterior chamber aspirate withdrawn, and ingress into anterior chamber measured. Postoperative observations included evaluation of the CCI using anterior segment optical coherence tomography (AS-OCT), change in central corneal thickness (CCT), and anterior segment inflammation at 1 day, 1 week, and 1 month and endothelial cell loss and surgically induced astigmatism (SIA) at 3 months. Incision enlargement (P<.001) and trypan blue ingress in the anterior chamber (mean 1.7 log units ± 0.6 [SD] versus 3.8 ± 0.6 log units, P<.001) was significantly greater in Group 1 (n = 50) than in Group 2 (n = 50). On AS-OCT, endothelial misalignment and gaping were more frequent in Group 1 at 1 day (P=.001) and 1 week (P=.018). There were no significant differences in SIA, change in CCT, endothelial cell loss, or anterior segment inflammation (P>.05). At the end of surgery, it is not the initial incision size alone but also the distortion of the incision during subsequent stages of surgery that determine the integrity of the CCI.

The goal of this study was to examine the current Japanese surgical payment system from the viewpoint of resource utilization. We collected data from surgical records in Teikyo University's electronic medical record system from April 1 through September 30, 2013. We defined the decision-making unit as a surgeon with the highest academic rank in the surgery. Inputs were defined as: 1) the number of medical doctors who assisted surgery and 2) the time of operation from skin incision to closure. An output was defined as the surgical fee. We calculated each surgeon's efficiency score using the output-oriented Banker-Charnes-Cooper model of data envelopment analysis. We compared the efficiency scores of each surgical specialty using the Kruskal-Wallis and Steel methods. We analyzed 2,825 surgical procedures performed by 103 surgeons. The difference in efficiency scores was significant (P = 0.0001). The thoracic surgeons were the most efficient and were more efficient than plastic, obstetric and gynecologic, urologic, otorhinolaryngologic, orthopedic, general, and emergency surgeons (P < 0.05). We demonstrated that surgeons' efficiency in operating rooms was significantly different among surgical specialties. This suggests that the Japanese surgical reimbursement scales fails to reflect resource utilization. © The Author(s) 2015.

To compare the surgically induced astigmatism (SIA) vector, flattening effect, torque, and wound architecture following femtosecond laser and manual clear corneal incisions (CCIs). In a double-armed, randomized, prospective case series, cataract surgery was performed for 600 eyes using femtosecond laser (300 eyes) or manual (300 eyes) 2.4-mm CCIs in temporal or superior oblique locations. SIA, flattening effect, torque, and the summated vector mean for SIA were calculated. Correlation with individual features was established and incision morphology was investigated by anterior segment optical coherence tomography at 3 months of follow-up. The SIA, flattening effect, and torque were lower in the femtosecond laser group for both incision locations, although the differences were not significant (all P > .05). The femtosecond laser group showed less dispersion of SIA magnitude and flattening effect. Temporal and superior oblique incisions resulted in flattening effect values of -0.11 and -0.21 diopters (D), respectively, in the femtosecond laser group and -0.13 and -0.34 D, respectively, in the manual group. Significant correlations with individual features were only found in the femtosecond laser group, with preoperative astigmatism being the only significant SIA predictor by multiple regression analysis (P = .003). Femtosecond laser CCIs showed less deviation from the intended length, wound enlargement, endothelial misalignment, and Descemet membrane detachments (all P < .037). Femtosecond laser CCIs were more reproducible. Although SIAs were smaller in femtosecond laser CCIs than in manual CCIs for both temporal and superior oblique incisions, the difference was not statistically significant. Association with individual features is highly variable. [J Refract Surg. 2018;34(5):322-329.]. Copyright 2018, SLACK Incorporated.

Neck dissection is one of the most commonly performed surgical procedures in the management of head and neck cancer. Different skin incisions with various modifications have been described in the literature. Three commonly used but conceptually different incisions were compared with respect to the incidence of wound dehiscence in a retrospective review. There were 166 patients with 184 neck dissections carried out using a triradiate (n = 85), modified MacFee (n = 25), or an apron flap incision (n = 74). The incidence of wound dehiscence in the three groups was 11 percent, 8 percent, and 0 percent for the triradiate, modified MacFee, and apron flap incisions, respectively. There was a statistically significant difference in the incidence of wound dehiscence between the apron flap incision and the triradiate incision groups (p = 0.004). The difference in wound dehiscence was not statistically significant between the apron flap incision and the modified MacFee incision groups (p = 0.06). Overall, there was a significant increase in the incidence of wound dehiscence in previously irradiated necks (p = 0.02), but this was significant only for the triradiate incision (p = 0.005) when analyzed individually. Comparison of triradiate, apron, and MacFee incisions did not show a statistically significant difference between the incisions with regard to other postoperative complications in terms of seroma, hematoma, wound infection, and fistula formation. The apron flap incision is the recommended approach in the presence of previous neck irradiation as it gives easier access than the MacFee incision. The robustness of the flap is because of the absence of a trifurcate point as well as a good vascular supply arising from arterial territory of the external carotid artery.

The mid-to-lower segment of tibiofibular fractures (MLTFs) is commonly encountered in clinical practice, which is conventionally treated by the double-incision surgical approach. However, the double-incision approach frequently makes the closure of the wound extremely difficult and sometimes results in necrosis of skin around fractured sites. In the present study, our experience of using a single-incision surgical approach for treating MLTF was exhibited. From February 2005 to December 2013, the clinical outcomes of 212 patients with MLTFs who underwent either double-incision approach or single-incision approach were retrospectively evaluated and compared. Both groups were similar with respect to injury mechanism and all patients were followed up with the efficacies of treatment evaluated by Johner-Wruth criteria. The results demonstrated that the effective rate and the rate of excellent and good efficacy in the single-incision group were significantly higher than those in the double-incision group (P<0.05). In addition, the rates of skin wound healing and bone union after surgery in the single-incision group were significantly higher than those in the double-incision group (P<0.05). These findings indicate that the single-incision surgical approach, which holds the advantages of being milder in trauma, fewer in complications and better in function restoration, might be used as an alternative method for treating MLTFs.

The choice of the type of abdominal incision performed in caesarean delivery is made chiefly on the basis of the individual surgeon's experience and preference. A general consensus on the most appropriate surgical technique has not yet been reached. The aim of this systematic review of the literature is to compare the two most commonly used transverse abdominal incisions for caesarean delivery, the Pfannenstiel incision and the modified Joel-Cohen incision, in terms of acute and chronic post-surgical pain and their subsequent influence in terms of quality of life. Electronic database searches formed the basis of the literature search and the following databases were searched in the time frame between January 1997 and December 2013: MEDLINE, EMBASE Sciencedirect and the Cochrane Library. Key search terms included: "acute pain", "chronic pain", "Pfannenstiel incision", "Misgav-Ladach", "Joel Cohen incision", in combination with "Caesarean Section", "abdominal incision", "numbness", "neuropathic pain" and "nerve entrapment". Data on 4771 patients who underwent caesarean section (CS) was collected with regards to the relation between surgical techniques and postoperative outcomes defined as acute or chronic pain and future pregnancy desire. The Misgav-Ladach incision was associated with a significant advantage in terms of reduction of post-surgical acute and chronic pain. It was indicated as the optimal technique in view of its characteristic of reducing lower pelvic discomfort and pain, thus improving quality of life and future fertility desire. Further studies which are not subject to important bias like pre-existing chronic pain, non-standardized analgesia administration, variable length of skin incision and previous abdominal surgery are required.

Objective: To discuss the preliminary experience of single incision laparoscopic colorectal surgery. Methods: The clinical data and surgical outcomes of 104 selected patients who underwent single incision laparoscopic colorectal surgery in the 2 nd Department of General Surgery, Shengjing Hospital of China Medical University from January 2010 to September 2015 were retrospectively analyzed. There were 62 male and 42 female patients, aging from 21 to 87 years with a mean of (61±12) years. Eighty-five patients were diagnosed with malignancy while the rest 19 cases were benign diseases. All the procedures were performed by the same surgeon using the rigid laparoscopic instruments. Surgical and oncological outcomes were analyzed in 4 kinds of procedures which are over 5 cases respectively, including low anterior resection, abdominoperineal resection, radical right colon resection and radical sigmoidectomy. Results: Single incision laparoscopic colorectal surgery was performed in 104 selected patients and was successfully managed in 99 cases with a total conversion rate of 4.8%. Radical procedures for malignancy in cases with the number of patients more than 5 were performed for 74 cases. For low anterior resection, 35 cases with an average surgical time of (191±57) minutes, average estimated blood loss of (117±72) ml and average number of harvested lymph nodes of 14.6±1.1. For abdominoperineal resection, 9 cases with an average surgical time of (226±54) minutes, average estimated blood loss of (194±95) ml and average number of harvested lymph nodes of 14.1±1.5. For radical right colon resection, 16 cases with an average surgical time of (222±62) minutes, average estimated blood loss of (142±68) ml and average number of harvested lymph nodes of 15.4±2.4.

Emergency obstetric hysterectomy is a procedure that potentially preserves the life and the postpartum bleeding is the direct cause of its indication, the hemorrhage postpartum happens in 1% of obstetric patients. This study was carried out to identify women with potential risk for this event and to prevent this obstetric problem. The most frequent indications for hysterectomy were identified, as well as the sociodemographic characteristic of the patients. The surgical procedure carried out was extra-fascial technique with type Richardson hysterectomy modified; the surgical pieces went to the pathology service, to obtain the histopathological diagnosis. 43 cases of obstetric hysterectomy, were analyzed; the characteristics of this group showed that bigger percentage of this event was more frequent in 31 to 35 years (39.5%), with pregnancies at term (51.1%) in third pregnancies(27.9%), nulliparas (60.4%), with first cesarean section (39.5%), without previous abortions (79.0%). The most frequent obstetric complications were uterine atony and placenta accreta. The cause for uterine atony could be interstitial edema, as well as myometrial hypertrophy, because such histopathological diagnoses were the most common. Odds ratio showed that a patient with cesarean section has 1.16 more probabilities of suffering hysterectomy than a woman with childbirth. This study describes the histological presence of interstitial edema and myometrial hypertrophy as possible causes of uterine atony in the histological study of surgical specimen. This could be related to no response of myometrial to the uterus-tonic effect of oxytocin. Obstetric uterine dysfunction has multifactorial cause. Patients with the characteristics described in this study should be considered as high risk.

Laparoscopy was a progressive step to advancing surgical procedures as it minimised the scars left on the body after surgery, compared to traditional open surgery. Many years later, single-incision laparoscopic surgery (SILS) was created where, instead of having multiple incisions, only one incision is made or multiple small incisions in one location. SILS, or laparoendoscopic single-site surgery (LESS), may produce lesser scars but drawbacks for the surgeons are still present. This paper aims to present related literature of the recent technological developments in laparoscopic tools and procedure particularly in the vision system, handheld instruments. Tech advances in LESS will also be shown. Furthermore, this review intends to give an update on what has been going on in the surgical robot market and state which companies are interested and are developing robotic systems for commercial use to challenge Intuitive Surgical's da Vinci Surgical System that currently dominates the market.

2018-05-18

To describe a technique of surgical peripheral iridectomy via a clear-cornea tunnel incision to prevent or treat pupillary block following phacoemulsification. Description of technique and retrospective description results in 20 eyes of 20 patients with acute angle closure with coexisting visually significant cataract undergoing phacoemulsification considered at risk of postoperative papillary block as well as two pseudo-phakic eyes with acute postoperative pupillary-block. Following phacoemulsification and insertion of an intraocular lens, a needle with a bent tip was inserted behind the iris through the corneal tunnel incision. A blunt iris repositor was introduced through the paracentesis and placed above the iris to exert posterior pressure and create a puncture. The size of the puncture was enlarged using scissors. For postoperative pupillary block the same technique was carried out through the existing incisions created for phacoemulsification. Peripheral iridectomy was successfully created in all 22 eyes. At a mean follow-up of 18.77 ± 9.72 months, none of the iridectomies closed or required enlargement. Two eyes had mild intraoperative bleeding and one eye a small Descemet's detachment that did not require intervention. No clinically significant complications were observed. Visual acuity and IOP improved or was maintained in all patients. The incidence of pupillary block in our hospital was 0.09% overall, 0.6% in diabetics and 3.5% in those with diabetic retinopathy. This technique of peripheral iridectomy via the cornea tunnel incision can be safely used during phacoemulsification in eyes at high risk of pupillary block or in the treatment of acute postoperative pupillary-block after cataract surgery. The technique is likely to be especially useful in brown iris, or if a laser is not available.

2012-01-01

Background and Objectives: To present our experience with a single-incision laparoscopic total colectomy, along with a literature review of all published cases on single-incision laparoscopic total colectomy. Methods: A total of 22 cases were published between 2010 and 2011, with our patient being case 23. These procedures were performed in the United States and United Kingdom. Surgical procedures included total colectomy with end ileostomy, proctocolectomy with ileorectal anastomosis, and total proctocolectomy with ileopouch-anal anastomosis. Intraoperative and postoperative data are analyzed. Results: Twenty-two of the 23 cases were performed for benign cases including Crohns, ulcerative colitis, and familial adenomatous polyposis. One case was performed for adenocarcinoma of the cecum. The mean age was 35.3 years (range, 13 to 64), the mean body mass index was 20.1 (range, 19 to 25), mean operative time was 175.9 minutes (range, 139 to 216), mean blood loss was 95.3mL (range, 59 to 200), mean incision length was 2.61cm (range, 2 to 3). Average follow-up was 4.6 months with 2 reported complications. Conclusions: Single-incision laparoscopic total colectomy is feasible and safe in the hands of an experienced surgeon. It has been performed for both benign and malignant cases. It is comparable to the conventional multi-port laparoscopic total colectomy. PMID:22906326

Columellar and nostril shapes often present irregularity after transcolumellar incision for open rhinoplasty, because of the contracture of the incised wound. The present study introduces a new technique to prevent this complication, and verifies its efficacy in improving cosmetic appearance. In our new method, a zig-zag incision with three small triangular flaps is made on the columella and in the pericolumellar regions of the bilateral nostril rims. Since the shape of the incision resembles the contour of an inverted "batman", we term our new method the "Inverted Batman" incision. To verify the effectiveness of the Inverted Batman incision, aesthetic evaluation was conducted for 21 patients operated on using the conventional transcolumellar incision (Conventional Group) and 19 patients operated on using the Inverted Batman incision (Inverted Batman Group). The evaluation was performed by three plastic surgeons, using a four-grade scale to assess three separate items: symmetry of bilateral soft triangles, symmetry of bilateral margins of the columella, and evenness of the columellar surface. The scores of the two groups for these three items were compared using a non-parametric test (Mann-Whitney U-test). With all three items, the Inverted Batman group patients present higher scores than Conventional Group patients. The Inverted Batman incision is effective in preserving the correct anatomical structure of the columella, soft triangle, and nostril rims. Hence, we recommend the Inverted Batman incision as a useful technique for open rhinoplasty.

To explore the relationship between CD4(+) T lymphocyte cell count and prognosis as well as healing of the surgical incision in HIV/AIDS patients who had received operation. Data were collected and analysed retrospectively from 234 HIV/AIDS patients hospitalized at the Beijing Ditan hospital who underwent operation between January 2008 and December 2012. Following factors were taken into consideration that including:age, gender, time and where that anti-HIV(+) was diagnosed, CD4(+)T lymphocyte cell count at the time of operation, part of the body that being operated, typology of incision, different levels of healing on the surgical incision, infection at the incision site, post-operative complications and the prognosis, etc. Wilcoxon rank sum test, χ(2) test, Kruskal-Wallis H test and Spearman rank correlation were used for statistical analysis to compare the different levels on healing of the incision in relation to the different CD4(+)T lymphocyte cell counts. Rates of level A healing under different CD4(+)T cell counts were also compared. 1) Among the 234 patients including 125 males and 109 females, the average age was 36.17±11.56 years old. Time after discovery of anti-HIV(+)was between 0 and 204 months. The medium CD4(+)T cell count was 388.5 cell/µl; 23.93% of the patients having CD4(+)T lymphocyte cell counts as <200 cell/µl. 2) 7.26% of the operations were emergent. There were 23 different organs affected at the time of operation, due to 48 different kinds of illness. 21.37% of the operations belonged to class I incision, 49.57% was class II incision and 29.06% was class III incision. 86.32% of the incisions resulted in level A healing, 12.51% resulted in level B and 1.71% in level C. 4.27% of the patients developed post-operative complications. Differences between level A healing and level B or C healing in terms of CD4(+)T lymphocyte cell count were not significant (P > 0.05). There was no statistically significant difference on the CD4(+) T

Although a variety of techniques for upper blepharoplasty have been described, few studies illustrate and clinically evaluate a system for marking incisions. Presented is a 10-year experience using a specific method for marking upper blepharoplasty incisions that consistently yielded excellent esthetic results. All upper blepharoplasties performed by the senior author between April, 1994 and April, 2004 were reviewed. Markings were designed to end the medial incision 6 mm from the angular vein, end the lateral incision 12 mm from the palpebral fissure, and to extend the incisions superiorly at 45 degrees. Over 10 years, 476 patients underwent cosmetic upper blepharoplasty. There were 22 (4.6%) revisions. Eighteen (3.8%) were performed in clinic using CO2 laser, and 4 (0.8%) patients required surgical revision. Patient satisfaction was high, and no scars were visible outside the brow. Excellent outcomes can be expected using this simple, reproducible, and widely applicable system for marking upper blepharoplasty incisions.

Abscess incision and drainage in the emergency department--Part I.

PubMed

Halvorson, G D; Halvorson, J E; Iserson, K V

1985-01-01

Superficial abscesses are commonly seen in the emergency department. In most cases, they can be adequately treated by the emergency physician without hospital admission. Treatment consists of surgical drainage with the addition of antibiotics in selected cases. Incision is generally performed using local anesthesia, with intraoperative and postoperative systemic analgesia. Care must be taken to make a surgically appropriate incision that allows adequate drainage without injuring important structures. Postoperative care includes warm soaks, drains or wicks, analgesia, and close follow-up. Antibiotics are usually unnecessary. Complications of incision and drainage include damage to adjacent structures, bacteremic complications, misdiagnosis of such entities as mycotic aneurysms, and spread of infection owing to inadequate drainage. The infectious agents responsible for abscess formation are numerous and depend largely on the anatomic location of the abscess. Staphylococcus aureus accounts for less than half of all cutaneous abscesses. Anaerobic bacteria are common etiologic agents in the perineum and account for the majority of all cutaneous abscesses. Abscesses at specific locations involve special consideration for diagnosis and treatment and may require specialty consultation.

2018-05-16

A quaternized reverse thermal gel (RTG) aimed at replacing current surgical incision drapes (SIDs) was designed and characterized. The antimicrobial efficacy of the quaternized RTG was analyzed using both in vitro and in vivo models and was compared to standard SIDs. Polymer characterization was completed using both nuclear magnetic resonance ( 1 H NMR) and lower critical solution temperature (LCST) analysis. Biocompatibility was assessed using a standard cell viability assay. The in vitro antimicrobial efficacy of the polymer was analyzed against four common bacteria species using a time-kill test. The in vivo antimicrobial efficacy of the polymer and standard SIDs were compared using a murine model aimed at mimicking surgical conditions. NMR confirmed the polymer structure and presence of quaternized groups and alkyl chains. The polymer displayed a LCST of 34 °C and a rapid rate of gelation, allowing stable gel formation when applied to skin. Once quaternized, the polymer displayed an increase in kill-rate of bacteria compared to unquaternized polymer. In experiments aimed at mimicking surgical conditions, the quaternized polymer showed statistically comparable bacteria-killing capacity to the standard SID and even surpassed the SID for killing capacity at various time points. A novel approach to replacing current SIDs was developed using an antimicrobial polymer system with RTG properties. The RTG properties of this polymer maintain a liquid state at low temperatures and a gel upon heating, allowing this polymer to form a tight coating when applied to skin. Furthermore, this polymer achieved excellent antimicrobial properties in both in vitro and in vivo models. With further optimization, this polymer system has the potential to replace and streamline presurgical patient preparations through its easy application and beneficial antimicrobial properties.

Certain postoperative wounds are recognised to be associated with more complications than others and may be termed high-risk. Wound healing can be particularly challenging following high-energy trauma where wound necrosis and infection rates are high. Surgical incision for joint arthrodesis can also be considered high-risk as it requires extensive and invasive surgery and postoperative distal limb swelling and wound dehiscence are common. Recent human literature has investigated the use of negative pressure wound therapy (NPWT) over high-risk closed surgical incisions and beneficial effects have been noted including decreased drainage, decreased dehiscence and decreased infection rates. In a randomised, controlled study twenty cases undergoing distal limb high-energy fracture stabilisation or arthrodesis were randomised to NPWT or control groups. All cases had a modified Robert-Jones dressing applied for 72 h postoperatively and NPWT was applied for 24 h in the NPWT group. Morphometric assessment of limb circumference was performed at six sites preoperatively, 24 and 72 h postoperatively. Wound discharge was assessed at 24 and 72 h. Postoperative analgesia protocol was standardised and a Glasgow Composite Measure Pain Score (GCPS) carried out at 24, 48 and 72 h. Complications were noted and differences between groups were assessed. Percentage change in limb circumference between preoperative and 24 and 72 h postoperative measurements was significantly less at all sites for the NPWT group with exception of the joint proximal to the surgical site and the centre of the operated bone at 72 h. Median discharge score was lower in the NPWT group than the control group at 24 h. No significant differences in GCPS or complication rates were noted. Digital swelling and wound discharge were reduced when NPWT was employed for closed incision management. Larger studies are required to evaluate whether this will result in reduced discomfort and complication rates postoperatively.

Surgical site infection (SSI) and wound dehiscence are dreaded complications following laparotomy in general surgical patients, and can potentially occur more often in various comorbid states. Negative-pressure wound therapy (NPWT) has a positive effect of on open and complicated wounds and so has been used for at-risk surgical incisions with the aim of redistributing lateral tension and holding incision edges together. The aim of the present study was to compare the rate of wound complications following laparotomy in high-risk general surgical patients with a clean incision treated with closed-incision negative-pressure therapy (ciNPT) with those receiving conventional care. A retrospective review was performed of the hospital medical records of patients who underwent laparotomy between 1 October 2010 and 31 March 2012. Records of 69 patients who received ciNPT and 112 who were managed by adherent gauze dressings were included in the final analysis. Two (2.9%) patients in the ciNPT group and 23 (20.5%) in the non-NPWT group developed a wound complication following laparotomy (P < 0.0009). The relative risk (RR) was 0.14 (0.03-0.58), suggesting that infection is less likely to occur in ciNPT-treated incisions, compared with gauze dressings. ciNPT was associated with a positive clinical outcome and was a safe and effective method of postsurgical management in our general surgery patients considered to have risk of developing wound complications following laparotomy. © 2016 The Authors.

Post-sternotomy mediastinitis is a serious complication after cardiothoracic surgery and contribute significantly to post-operative morbidity, mortality, and healthcare costs. Negative pressure wound therapy is today’s golden standard for post-sternotomy mediastinitis treatment. A systematic literature search was conducted at PubMed until October 2012 to analyse whether vacuum-assisted closure technique prevents mediastinitis after clean surgical incisions closure. Today’s studies showed reduction of post-sternotomy mediastinitis including a beneficial socio-economic impact. Current studies, however included only high-risk patients, hence furthermore, larger randomised controlled trials are warranted to clarify the benefit for using surgical incision vacuum management systems in the general patient population undergoing sternotomy and clarify risk factor interaction.

This paper presents a novel force modeling for an incision surgery into tissue and its haptic application for a surgeon. During the robot-assisted incision surgery, it is highly urgent to develop the haptic system for realizing sense of touch in the surgical area because surgeons cannot sense sensations. To achieve this goal, the force modeling related to reaction force of biological tissue is proposed in the perspective on energy. The force model describes reaction force focused on the elastic feature of tissue during the incision surgery. Furthermore, the force is realized using calculated information from the model by haptic device using magnetorheological fluid (MRF). The performance of realized force that is controlled by PID controller with open loop control is evaluated.

To compare intraocular pressure (IOP) immediately after cataract surgery, and surgically induced corneal astigmatism (SIA) and corneal shape changes between eyes with transconjunctival single-plane sclerocorneal incisions (TSSIs) and eyes with clear corneal incisions (CCIs). Bilateral eyes of 64 patients undergoing phacoemulsification were randomized to undergo 2.4-mm temporal TSSI or CCI. IOP was measured preoperatively, and in the immediate postoperative periods. SIA was determined using vector analysis, and corneal shape changes and irregular astigmatism were evaluated using a videokeratography preoperatively, and in the early postoperative periods. Wound hydration was performed in 23 eyes (35.9 %) of the TSSI group and in 60 (93.8 %) of the CCI group (P < 0.0001). Mean IOP was significantly higher in the TSSI group than in the CCI group at 30, 60, and 120 min postoperatively (P ≤ 0.0179). SIA tended to be smaller in the TSSI group than the CCI group, but the difference was not significant. The higher order irregular astigmatism was smaller in the TSSI group than in the CCI group at 2 days (P = 0.0312). The videokeratography revealed a wound-related flattening postoperatively in both groups; this change disappeared within 4 weeks in the TSSI group, whereas it persisted until 12 weeks in the CCI group. IOP was significantly higher immediately after TSSI than after CCI and required less wound hydration, suggesting better stability with TSSI. Higher order irregular astigmatism and wound-related corneal flattening were smaller after TSSI than after CCI in the early periods, suggesting that fewer corneal shape changes with TSSI.

Gynecomastia is characterized by the benign proliferation of breast tissue in men. Herein, we present a new method for the treatment of gynecomastia, using ultrasound-assisted liposuction with both conventional and reverse-cutting edge tip cannulas in combination with a pull-through lipectomy technique with pituitary forceps through a single transaxillary incision. Thirty patients were treated with this technique at the author's institution from January 2010 to January 2015. Ten patients were treated with conventional surgical excision of the glandular/fibrous breast tissue combined with liposuction through a periareolar incision before January 2010. Medical records, clinical photographs and linear analog scale scores were analyzed to compare the surgical results and complications. The patients were required to rate their cosmetic outcomes based on the linear analog scale with which they rated their own surgical results; the mean overall average score indicated a good or high level of satisfaction. There were no incidences of skin necrosis, hematoma, infection and scar contracture; however, one case each of seroma and nipple inversion did occur. Operative time was reduced overall using the new technique since it is relatively simple and straightforward. According to the evaluation by the four independent researchers, the patients treated with this new technique showed statistically significant improvements in scar and nipple-areolar complex (NAC) deformity compared to those who were treated using the conventional method. Glandular liposculpture through a single transaxillary incision is an efficient and safe technique that can provide aesthetically satisfying and consistent results.

Cranial nerve injury (CNI) is the most common neurological complication associated with carotid endarterectomy (CEA). Some authors postulate that the transverse skin incision leads to increased risk of CNI. We compared the incidence of CNI associated with the transverse and longitudinal skin incisions in a high-volume cerebrovascular center. We reviewed the charts of 226 consecutive patients who underwent CEAs between January 2007 and August 2009. Pre- and postoperative standardized neurological evaluations were performed by faculty neurologists and neurosurgeons. One hundred sixty nine of 226 (75%) CEAs were performed with the use of a transverse incision. The longitudinal incision was generally reserved for patients with a high-riding carotid bifurcation. Mean patient age was 69 years (range, 45-91 years); 62% were men; 59% of patients were symptomatic and had high-grade stenosis (70%-99%). CNI occurred in 8 cases (3.5%): 5 (3%) in transverse and 3 (5.3%) with longitudinal incisions (P = .42). There were 2 marginal mandibular nerve injuries, 1 (0.6%) transverse and 1 longitudinal; 5 recurrent laryngeal nerve injuries, 4 transverse and 1 longitudinal; and 1 case of hypoglossal nerve injury associated with longitudinal incision. One hematoma was associated with CNI. All injuries were transient. Fourteen wound hematomas required surgical evacuation. The transverse skin incision for CEAs is not associated with an increased risk of CNI (P =.42). In this study, the incidence of CNI associated with the transverse incision was 3% (n = 5) vs 5% (n = 3) for longitudinal incisions. All CNIs were temporary.

The epicanthus, a lengthways cambered skinfold around the inner canthus, is particularly common in Orientals. The purpose of this study was to evaluate the surgical outcomes for patients with epicanthus after the application of a new surgical technique. A total of 753 patients with epicanthus underwent epicanthoplasty in our hospital from October 2009 to March 2017 and were enrolled in this study. All patients were treated with upper arch flap combined with extended incision of the lower eyelid surgical method, and the effects of the surgery were assessed by photographic analysis and satisfaction surveys. After the surgery, the eyelids of patients were elongated, and their inner canthi diameter was shortened without recurrence in the epicanthus. For 3.32% of the patients, there was a nonuniform edge thickness of the lower eyelid incision; for 8.23% of the patients, there was a slightly lighter skin color in the rest of quondam arch flap. Six months after the surgery, the incision scar was not obvious for all patients, and most of the patients (90.31%) were satisfied with the effect of the surgery. The upper arch flap combined with extended incision of the lower eyelid surgical method, a simple and effective surgical correction method, obtained a good cosmetic result with more secluded scar and high satisfaction for patients with epiblepharon.

To determine the feasibility and safety of transverse fundal incision with manual placental removal in women with placenta praevia and possible placenta accreta. Case series. Four level-three Japanese obstetric centres. Thirty-four women with prior caesarean section and placenta praevia that widely covers the anterior uterine wall, in whom placenta accreta cannot be ruled out. A transverse fundal incision was performed at the time of caesarean section and manual placental removal was attempted under direct observation. Operative fluid loss. The total volume of fluid lost during our operative procedure compares favourably with the volume lost during our routine transverse lower-segment caesarean sections performed in patients without placenta praevia or accreta. The average fluid loss was 1370 g. No patients required transfer to intensive care, and there were no cases of fetal anaemia. This procedure has the potential to reduce the heavy bleeding that arises from caesarean deliveries in women with placenta praevia and placenta accreta. © 2013 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2013 RCOG.

The healing process in guinea pig skin following surgical incisions was evaluated at the molecular level, in vivo, by the use of Raman spectroscopy. After the incisions were closed either by suturing or by laser tissue welding (LTW), differences in the respective Raman spectra were identified. The study determined that the ratio of the Raman peaks of the amide III (1247 cm−1) band to a peak at 1326 cm−1 (the superposition of elastin and keratin bands) can be used to evaluate the progression of wound healing. Conformational changes in the amide I band (1633 cm−1 to 1682 cm−1) and spectrum changes in the range of 1450 cm−1 to 1520 cm−1 were observed in LTW and sutured skin. The stages of the healing process of the guinea pig skin following LTW and suturing were evaluated by Raman spectroscopy, using histopathology as the gold standard. LTW skin demonstrated better healing than sutured skin, exhibiting minimal hyperkeratosis, minimal collagen deposition, near-normal surface contour, and minimal loss of dermal appendages. A wavelet decomposition-reconstruction baseline correction algorithm was employed to remove the fluorescence wing from the Raman spectra. PMID:19581109

Background and Objectives: For reduced port surgery in pediatric patients, the initial umbilical incision plays an important role in both functional ability and cosmetic impact. Larger umbilical incisions enable better manipulation of forceps, extraction of larger surgical specimens, and easier exteriorization of the intestine for anastomosis. We have pursued an incision of the small pediatric umbilicus that allows for enlargement of the orifice of the abdominal opening with preservation of the natural umbilical profile. This article aims to present a new umbilical incision technique and describe the outcomes. Methods: We devised a new umbilical incision technique for reduced port surgery in pediatric patients. Our incision is made in an inverted Y shape (Benz incision), allowing for access port device insertion. The Benz incision technique was applied between November 2010 and May 2014 and was retrospectively studied. Results: Seventy-five patients underwent Benz incisions. The median age of all patients was 6 years 6 months (range, 26 days to 18 years), and the median body weight was 21.7 kg (range, 3.1–54.3 kg). Benz incisions were applied for various procedures, including reduced port surgery with hepaticojejunostomy for congenital biliary dilatation, portojejunostomy for biliary atresia, Meckel diverticulectomy, tumor resection, varicocelectomy, cholecystectomy, splenectomy, ileus surgery, ileocecal resection, and total colectomy. All patients were successfully treated, without a significant increase in operating time or severe complications. The cosmetic profile of the umbilicus was maintained after surgery. Conclusion: The Benz incision is a feasible, effective, and scarless approach for reduced port surgery in pediatric patients whose umbilical rings are too small for the conventional approach.

Although pilonidal disease has been a well-known entity for more than a century, recurrence of pilonidal disease is still not rare. The optimal surgical approach to recurrent disease is under debate. In this study, we aimed to investigate the efficacy of "incision and curettage" procedure for recurrent pilonidal disease. From May 2009 to May 2013, 42 patients (37 male/5 female) underwent surgical treatment for recurrent pilonidal disease. Incision and curettage of granulation tissue, hair and debris in the cavity were performed in all cases. Data collection included demographics, visual analogue scale (VAS) score, hospital stay, return to daily activities (lying, sitting down in comfort) and work, and complete wound healing time. Mean operating time was 16.6±4.7 (10-24) minutes. Mean pain score was 1.4±1.1 (0-5) with VAS. The mean duration of returning to daily activities such as comfortable lying down, sitting and returning to work were 1.6±0.8 (1-4) days, and 3.3±2.3 (1-15) days, and 10.2±5.4 (5-33) days, respectively. The mean wound healing time was 19.9±7.8 (7-52) days. During the three-year follow-up period, no recurrence was observed. "Incision and curettage" may be performed as first-line treatment for recurrent cases. It does not require surgical skill and can be easily applied in a short time. This simple surgical option, incision curettage provides short hospital stay and quick return to daily activities, in addition to patient comfort and satisfaction.

The choice of the type of abdominal incision performed in caesarean delivery is made chiefly on the basis of the individual surgeon’s experience and preference. A general consensus on the most appropriate surgical technique has not yet been reached. The aim of this systematic review of the literature is to compare the two most commonly used transverse abdominal incisions for caesarean delivery, the Pfannenstiel incision and the modified Joel-Cohen incision, in terms of acute and chronic post-surgical pain and their subsequent influence in terms of quality of life. Electronic database searches formed the basis of the literature search and the following databases were searched in the time frame between January 1997 and December 2013: MEDLINE, EMBASE Sciencedirect and the Cochrane Library. Key search terms included: “acute pain”, “chronic pain”, “Pfannenstiel incision”, “Misgav-Ladach”, “Joel Cohen incision”, in combination with “Caesarean Section”, “abdominal incision”, “numbness”, “neuropathic pain” and “nerve entrapment”. Data on 4771 patients who underwent caesarean section (CS) was collected with regards to the relation between surgical techniques and postoperative outcomes defined as acute or chronic pain and future pregnancy desire. The Misgav-Ladach incision was associated with a significant advantage in terms of reduction of post-surgical acute and chronic pain. It was indicated as the optimal technique in view of its characteristic of reducing lower pelvic discomfort and pain, thus improving quality of life and future fertility desire. Further studies which are not subject to important bias like pre-existing chronic pain, non-standardized analgesia administration, variable length of skin incision and previous abdominal surgery are required.

This article reports the use of a customized surgical guide for simple and precise C-tube plate placement with minimized incision. Patients who were planning to have orthodontic miniplate treatment because of narrow interradicular space were recruited for this study. A combined silicone and stainless steel wire surgical guide for the C-tube was fabricated on the cast model. The taller wire of the positioning guide is used to accurately start the incision. The incision guide-wire position is verified by placing the miniplate on the coronal horizontal wire to confirm that the incision will coordinate with the screw holes. Because the miniplate is firmly held in place, there is no risk of the miniplate anchoring screws (diameter, 1.5 mm; length, 4 mm) sliding on the bone surface during placement with a manual hand driver. The surgical guide was placed on the clinical site, and it allowed precise placement of the miniplate with minimum incision and preventing from slippage or path-of-insertion angulation errors that might interfere with accurate placement. Customized surgical guide enables precise planning for miniplate positions in anatomically complex sites.

Surgical treatment of gynecomastia with severe ptosis: periareolar incision and dermal double areolar pedicle technique.

Cannistra, Claudio; Piedimonte, Andrea; Albonico, Fiorella

2009-11-01

Gynecomastia is a morphostructural impairment of the mammary region in men caused by parenchymal hypertrophy or a cutaneous distortion of breast skin covering or both. The clinical classification introduced by Simon et al. in 1973 ranks gynecomastia in three degrees. Each subtype can be treated with a specific technique. This article describes an alternative surgical procedure for treating gynecomastia with severe ptosis(type III and type IIIb of Simon's classification). Fifty-eight patients were treated for gynecomastia in our Plastic Surgery Unit from 1996 to 2004. The cutaneous excess of periareolar skin is evaluated by a pinching test. A circular periareolar mark is traced corresponding to the cutaneous excess that has to be removed.Initially, liposuction of adipous tissue on the periphery of the mammary region is performed through two cutaneous 3-mm incisions at the 3 o'clock and 9 o'clock positions around the areola. After this, the liposuction incisions are enlarged from 10 o'clock to 8 o'clock and from 2 o'clockto 4 o'clock to create access for the mastectomy. This dissection creates a double dermal areolar pedicle. The new areolar position is fixed with a Benelli round block suture. A resolution of the morphologic deformity without evident scars after hair growth and a correction of the breast deformity has been observed in the 6-month follow-ups conducted for all the patients. We observed that the vascular-nervous net under the areola at 12 o'clock and 6 o'clock is very important, more so than the lateral pedicle, and the conservation of a double vascular-nervous pedicle reduces significantly the risk of areolar necrosis, especially in cases of gynecomastia type III and in cases where there is a high degree of breast malformation such as the tuberous breast.

It has passed 150th birth anniversary of a great, Italian Obstetrician Eduardo Porro, author of a cesarean section technique consisted of uterine corpus amputation and suturing of the cervix stump into the abdominal wall incision. Eduardo Porro was born in 1842 in Padwa. In 1876, he became the Head of Obstetrics Department in Pawia, and since 1882, the Head of Midwifery School in Milano. He died on May 25th, 1901. That original cesarean section method was introduced by him in 1876. Its main idea was exsection of the uterus, infected at the time of labor. The operation was also performed because of other reasons, such as: wide uterine ruptures, osteomalation, spacions vaginal cicatrization, and uterine atony. In the second part of the 18th century, maternal mortality following so called, classical cesarean section was nearly 100 percent. Introducing the Porro's operative technique decreased maternal mortality to 58%. This method aroused an interest of cesarean section technique improvement at all. The twilight, of the Porro's operation took place in the 1920s as the new method appeared, elaborated by Adolf Kehrer--uterine lower segment transverse incision.

The location of incision in cataract surgery and its impact on induced astigmatism.

2016-01-01

The purpose of the present study is a systematic review of previous studies on choosing the best incision site for the correction of astigmatism in cataract surgery and assessing the amount of surgically induced astigmatism (SIA) with each approach. Regardless of astigmatism axis, studies show that using an on-axis incision is associated with favorable results for 0.5-1.0 diopter (D) of astigmatism. In cases with more than 1.0 D astigmatism, paired on-axis incisions can be appreciably efficient in astigmatism correction and cause at least 1.5 D SIA. Considering the amount of SIA, a temporal incision is the best approach when the patient has minimal amounts of corneal astigmatism preoperatively. At higher levels of astigmatism, if no other astigmatism correction method is used simultaneously, the temporal incision is used less frequently; however, since it is associated with the least SIA, it is still the choice site when another correction method is used. The temporal incisions in cataract surgery are associated with little SIA and are appropriate choices for mild preoperative astigmatism. At higher levels of preoperative astigmatism, superior incisions are associated with better results when combined methods are not applied.

A subciliary incision may be associated with various complications of the lower eyelid when it is used during a total maxillectomy. The use of the transconjunctival incision instead is an alternative in suitable patients. The records of 17 patients were reviewed in whom a transconjunctival incision was used during total maxillectomy. These included 13 in whom the Weber-Ferguson incision was used, and 4 who had a sublabial incision. There was mild conjunctival oedema in all the cases during the immediate postoperative period but it did not last for more than two days. Four patients had mild to moderate oedema of the lid that resolved within two days. One had mild ectropion with transient epiphora, which was caused by early removal of the medial canthal sutures. We found the approach to be cosmetically acceptable as it avoids a scar in the subciliary region. The transconjunctival incision can be used in place of the subciliary incision for lateral exposure during total maxillectomy. There are few complications associated with the lower lid, and it has good cosmetic results; if it is combined with a sublabial incision in suitable patients, the maxillectomy is virtually scar-free.

Obstetric Fistula in Burundi: a comprehensive approach to managing women with this neglected disease

PubMed Central

2013-01-01

Background In Burundi, the annual incidence of obstetric fistula is estimated to be 0.2-0.5% of all deliveries, with 1000–2000 new cases per year. Despite this relatively high incidence, national capacity for identifying and managing obstetric fistula is very limited. Thus, in July 2010, Medecins Sans Frontieres (MSF) set up a specialised Obstetric Fistula Centre in Gitega (Gitega Fistula Centre, GFC), the only permanent referral centre for obstetric fistula in Burundi. A comprehensive model of care is offered including psychosocial support, conservative and surgical management, post-operative care and follow-up. We describe this model of care, patient outcomes and the operational challenges. Methods Descriptive study using routine programme data. Results Between July 2010 and December 2011, 470 women with obstetric fistula presented for the first time at GFC, of whom 458 (98%) received treatment. Early urinary catheterization (conservative management) was successful in four out of 35 (11%) women. Of 454 (99%) women requiring surgical management, 394 (87%) were discharged with a closed fistula, of whom 301 (76%) were continent of urine and/or faeces, while 93 (24%) remained incontinent of urine and/or faeces. In 59 (13%) cases, the fistula was complex and could not be closed. Outcome status was unknown for one woman. Median duration of stay at GFC was 39 days (Interquartile range IQR, 31–51 days). The main operational challenges included: i) early case finding and recruitment for conservative management, ii) national capacity building in obstetric fistula surgical repair, and iii) assessing the psychosocial impact of this model. Conclusion In a rural African setting, it is feasible to implement a comprehensive package of fistula care using a dedicated fistula facility, and satisfactory surgical repair outcomes can be achieved. Several operational challenges are discussed. PMID:23965150

demonstrates that bilateral vertical femoral incisions used in EVAR have a wound infection rate of 2.0%. Infections are usually detected and treated clinically and empirically without the need for hospitalization or surgery. Asymptomatic groin wound fluid collections resolve significantly within 6 months without intervention. Therefore, surgical femoral artery exposure adds little morbidity to the endovascular repair of abdominal aortic aneurysms.

Burn contractures particularly involving the joints are challenging problems which might cause severe functional impairments. Many surgical techniques have been described for use, however, an ideal method yet to be found. Releasing incision is the most common and effective way to release the wide and severe contractures but it has some drawbacks. We propose a releasing incision technique combined with four Z plasty incisions to overcome the disadvantages of traditional releasing incision technique. We successfully used our releasing incision and quadra Z technique on seven consecutive patients with burn contractures between 2003 and 2005. We modified the classical releasing incision technique by adding four Z plasties; two of them with a common base on each corner of the incision line. In this technique, limitation of the webbing following the incision is made possible by the transposed flaps and unnecessary lateral extension of the incision and the defect was avoided, i.e. maximum release gain with minimal defect was provided. Satisfactory results were achieved in seven patients treated with this technique due to significant burn contractures between 2003 and 2005 with no significant complication. We propose this technique is suitable in all patients with severe burn contractures who require releasing incision and grafting.

Surgeons continually strive to improve technology and patient care. One remarkable demonstration of this is the development of laparoscopic surgery. Once this proved to be a safe and reliable surgical approach, robotics seemed a logical progression of surgical technology. The aim of this project was to evaluate the utility of robotics in the context of single-incision laparoscopic cholecystectomy (SILC). A retrospective review of a prospectively maintained database of robotic single-incision laparoscopic cholecystectomy (RSILC) and traditional SILC performed by a single surgeon at our institution from July 2010 to August 2013 was queried. All consecutive patients undergoing RSILC and SILC during this time period were included. Primary outcomes include conversion rate and operative time. Secondary outcomes include length of stay, duration of narcotic use, time to independent performance of daily activities and cost. Categorical variables were evaluated using Chi-square analysis and continuous variables using t test or Wilcoxon's rank test. Thirty-eight patients underwent RSILC and 44 underwent SILC. BMI was higher in the RSILC group, and the number of patients with prior abdominal surgeries was higher in the SILC group. Otherwise, demographics were similar between the two groups. There was no difference in conversion rate between RSILC and SILC (8 vs 11 %, p = 0.60). Mean operative time for RSILC was significantly greater compared with SILC (98 vs 68 min, p < 0.0001). RSILC was associated with a longer duration of narcotic use (2.3 vs 1.7 days, p = 0.0019) and time to independent performance of daily activities (4 vs 2.3 days, p < 0.0001). Total cost is greater in RSILC ($8961 vs $5379, p < 0.0001). While RSILC can be safely performed, it is associated with longer operative times and greater cost.

The present study aimed to discuss the advantage of the application of a cervical low incision for functional neck dissection in patients with thyroid papillary carcinoma. The study was a retrospective analysis of 87 thyroid papillary carcinoma patients; cervical low incision in the functional neck dissection was applied for 47 cases and the classic 'L' incision was applied for 40 cases. The different integrity, surgical time, blood loss and the aesthetic property of the incision were compared between the cervical low incision and the classic 'L' incision for lateral neck dissection of thyroid cancer. The postoperative pathological diagnosis was that the average total amount and the region II lymph nodes of the unilateral neck dissection were 33 and 10 for the cervical low incision group, and 32 and 11 for the classic 'L' incision group, respectively (P>0.05). The average unilateral neck dissection times were 87 and 58 min for the cervical low incision group and the classic 'L' incision group, respectively (P<0.05). The blood loss of the cervical low incision group was 67 ml, while the loss for the classic 'L' incision group was 61 ml (P>0.05). The postoperative incision of the cervical low incision group was smaller and more concealing. Additionally, the cosmetic deformities were milder for an inconspicuous cervical scar, and the sensation was improved for the patients in comparison with the classic 'L' incision group. These results suggest that the application of cervical low incision for functional neck dissection in thyroid papillary carcinoma patients aids in reducing postoperative complications, without increasing recurrence rates. Therefore, the classic 'L' incision can be replaced by the cervical low incision.

Single-incision laparoscopic surgery (SILS) is gaining popularity for a wide variety of surgical operations and capitalizes on the benefits of traditional laparoscopic surgery without incurring multiple incision sites. Traditionally, SILS is performed by a midline periumbilical approach. However, such a minimally invasive approach may be utilized in patients who already have an abdominal incision. Our series retrospectively reviews 7 cases in which we utilized the fascial defect at the time of after ostomy reversal as our SILS incision site. In turn, we performed a variety of concurrent intra-abdominal procedures with excellent technical success and outcomes. Our study is the largest single-institution case series of this novel approach and suggests that utilizing an existing ostomy-site abdominal incision is a safe and effective location for SILS port placement and should be considered in patients undergoing concurrent procedures.

Introduction: Data on specific characteristics based on the gender of the unborn baby and their significance for obstetrics are limited. The aim of this study is to analyse selected parameters of obstetric relevance in the phases pregnancy, birth and postpartum period in dependence on the gender of the foetus. Materials and Methods: The selected study method comprised a retrospective data acquisition and evaluation from the Austrian birth register of the Department of Clinical Epidemiology of Tyrolean State Hospitals. For the analysis all inpatient singleton deliveries in Austria during the period from 2008 to 2013 were taken into account (live and stillbirths n = 444 685). The gender of the baby was correlated with previously defined, obstetrically relevant parameters. Results: In proportions, significantly more premature births and sub partu medical interventions (vaginal and abdominal surgical deliveries. episiotomies) were observed for male foetuses (p < 0.001). The neonatal outcome (5-min Apgar score, umbilical pH value less than 7.1, transfer to a neonatal special unit) is significantly poorer for boys (p < 0.001). Discussion: In view of the vulnerability of male foetuses and infants, further research is needed in order to be able to react appropriately to the differing gender-specific requirements in obstetrics.

TRPV1, but not TRPA1, in primary sensory neurons contributes to cutaneous incision-mediated hypersensitivity

PubMed Central

2013-01-01

Background Mechanisms underlying postoperative pain remain poorly understood. In rodents, skin-only incisions induce mechanical and heat hypersensitivity similar to levels observed with skin plus deep incisions. Therefore, cutaneous injury might drive the majority of postoperative pain. TRPA1 and TRPV1 channels are known to mediate inflammatory and nerve injury pain, making them key targets for pain therapeutics. These channels are also expressed extensively in cutaneous nerve fibers. Therefore, we investigated whether TRPA1 and TRPV1 contribute to mechanical and heat hypersensitivity following skin-only surgical incision. Results Behavioral responses to mechanical and heat stimulation were compared between skin-incised and uninjured, sham control groups. Elevated mechanical responsiveness occurred 1 day post skin-incision regardless of genetic ablation or pharmacological inhibition of TRPA1. To determine whether functional changes in TRPA1 occur at the level of sensory neuron somata, we evaluated cytoplasmic calcium changes in sensory neurons isolated from ipsilateral lumbar 3–5 DRGs of skin-only incised and sham wild type (WT) mice during stimulation with the TRPA1 agonist cinnamaldehyde. There were no changes in the percentage of neurons responding to cinnamaldehyde or in their response amplitudes. Likewise, the subpopulation of DRG somata retrogradely labeled specifically from the incised region of the plantar hind paw showed no functional up-regulation of TRPA1 after skin-only incision. Next, we conducted behavior tests for heat sensitivity and found that heat hypersensitivity peaked at day 1 post skin-only incision. Skin incision-induced heat hypersensitivity was significantly decreased in TRPV1-deficient mice. In addition, we conducted calcium imaging with the TRPV1 agonist capsaicin. DRG neurons from WT mice exhibited sensitization to TRPV1 activation, as more neurons (66%) from skin-incised mice responded to capsaicin compared to controls (46%), and the

This prospective, double-blind, randomized, controlled trial was designed to compare the outcome of diathermy incisions versus scalpel incisions in general surgery. A total of 369 patients who underwent diathermy incision (group A: 185 patients) or scalpel incision (group B: 184 patients) were analyzed. Variables analyzed were: surgical wound classification, length and depth of incision, incision time, duration of operation, incisional blood loss, postoperative pain, duration of hospital stay, duration of healing, and postoperative complications. The inclusion criteria were all patients who underwent elective or emergency general surgery. The exclusion criteria were only cases with incomplete patients' data and patients who were lost to follow-up. This study was conducted at Fatima Hospital-Baqai Medical University and Shamsi Hospital (Karachi), from January 2006 to December 2007. Incision time was significantly longer for patients in group B (p = 0.001). Incisional blood loss also was more for patients in group B (p = 0.000). Pain perception was found to be markedly reduced during the first 48 h in group A (p = 0.000). Total period of hospital stay (p = 0.129) and time for complete wound healing (p = 0.683) were almost the same for both groups. Postoperative complication rate by wound classification did not differ markedly between the two groups (p = 0.002 vs. p = 0.000). Diathermy incision has significant advantages compared with the scalpel because of reduced incision time, less blood loss, & reduced early postoperative pain.

To evaluate the current state of abortion training in Canadian Obstetrics and Gynecology residency programs. Surveys were distributed to all Canadian Obstetrics and Gynecology residents and program directors. Data were collected on inclusion of abortion training in the curriculum, structure of the training and expected competency of residents in various abortion procedures. We distributed and collected surveys between November 2014 and May 2015. In total, 301 residents and 15 program directors responded, giving response rates of 55% and 94%, respectively. Based on responses by program directors, half of the programs had "opt-in" abortion training, and half of the programs had "opt-out" abortion training. Upon completion of residency, 66% of residents expected to be competent in providing first-trimester surgical abortion in an ambulatory setting, and 35% expected to be competent in second-trimester surgical abortion. Overall, 15% of residents reported that they were not aware of or did not have access to abortion training within their program, and 69% desired more abortion training during residency. Abortion training in Canadian Obstetrics and Gynecology residency programs is inconsistent, and residents desire more training in abortion. This suggests an ongoing unmet need for training in this area. Policies mandating standardized abortion training in obstetrics and gynecology residency programs are necessary to improve delivery of family planning services to Canadian women. Abortion training in Canadian Obstetrics and Gynecology residency programs is inconsistent, does not meet resident demand and is unlikely to fulfill the Royal College of Physicians and Surgeons of Canada objectives of training in the specialty.

The objective of this study is to test the null hypothesis that an S-shaped surgical incision versus conventional (straight) skin incision in the creation of autogenous radiocephalic arteriovenous fistulas (RCAVFs) have no impact on the primary end-point of primary functional maturation and secondary end points of stenosis and thrombosis. A prospective observational comparative consecutive study with intention-to-treat on individuals undergoing only radiocephalic arteriovenous fistula (RCAVFs) over a period of 12 months was conducted. Variables on patient's demographics, comorbidities, anesthesia type, mean arterial blood pressure, thrill, laterality, cephalic vein and radial artery diameter were collated. The test of probability was assessed through Chi-Square, Kaplan-Meier survival estimator and Log-Rank analysis. Total of n = 83 individuals with median age of 67 years (IQR, 20-89) and male predominance 83% during this period were subjected to RCAVF formation. Total of n = 45 patients in straight skin incision were compared to n = 38 individuals in S-shaped group. Despite equal prevalence of demographics, comorbidities, anesthesia type, mean arterial blood pressure (MAP), thrill, laterality, cephalic vein and radial artery diameter ( p  > 0.05) higher incidence of juxta-anastomotic stenosis was noted in the straight skin incision group ( p  = 0.029) in comparative and survival analysis (Log-Rank, p  = 0.036). The maturation of the entire cohort was 69% (S-shaped 76% vs. straight group 62%) (p > 0.05). The outcome of this study demonstrates that S-shaped surgical skin incision is associated with a lower incidence of stenosis in comparison to straight incision type in RCAVF formation.

Transumbilical single incision laparoscopic surgery (SILS) offers excellent cosmetic results and may be associated with decreased postoperative pain, reduced need for analgesia, and thus accelerated recovery. Herein, we report the first transumbilical single incision laparoscopic pancreatectomy case in a patient who had renal cell cancer metastasis on her pancreatic corpus and tail. A 59-year-old female who had metastatic lesions on her pancreas underwent laparoscopic subtotal pancreatectomy through a 2-cm umbilical incision. Single incision pancreatectomy was performed with a special port (SILS port) and articulated equipment. The procedure lasted 330 minutes. Estimated blood loss was 100mL. No perioperative complications occurred. The patient was discharged on the seventh postoperative day with a low-volume (20mL/day) pancreatic fistula that ceased spontaneously. Pathology result of the specimen was renal cell cancer metastases. This is the first reported SILS pancreatectomy case, demonstrating that even advanced surgical procedures can be performed using the SILS technique in well-experienced centers. Transumbilical single incision laparoscopic pancreatectomy is feasible and can be performed safely in experienced centers. SILS may improve cosmetic results and allow accelerated recovery for patients even with malignancy requiring advanced laparoscopic interventions.

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.

Transconjuctival Incision with Lateral Paracanthal Extension for Corrective Osteotomy of Malunioned Zygoma

PubMed Central

Chung, Jae-Ho; You, Hi-Jin; Hwang, Na-Hyun; Yoon, Eul-Sik

2016-01-01

Background Conventional correction of malunioned zygoma requires complete regional exposure through a bicoronal flap combined with a lower eyelid incision and an upper buccal sulcus incision. However, there are many potential complications following bicoronal incisions, such as infection, hematoma, alopecia, scarring and nerve injury. We have adopted a zygomaticofrontal suture osteotomy technique using transconjunctival incision with lateral paracanthal extension. We performed a retrospective review of clinical cases underwent correction of malunioned zygoma with the approach to evaluate outcomes following this method. Methods Between June 2009 and September 2015, corrective osteotomies were performed in 14 patients with malunioned zygoma by a single surgeon. All 14 patients received both upper gingivobuccal and transconjunctival incisions with lateral paracanthal extension. The mean interval from injury to operation was 16 months (range, 12 months to 4 years), and the mean follow-up was 1 year (range, 4 months to 3 years). Results Our surgical approach technique allowed excellent access to the infraorbital rim, orbital floor, zygomaticofrontal suture and anterior surface of the maxilla. Of the 14 patients, only 1 patient suffered a complication—oral wound dehiscence. Among the 6 patients who received infraorbital nerve decompression, numbness was gradually relieved in 4 patients. Two patients continued to experience persistent numbness. Conclusion Transconjunctival incision with lateral paracanthal extension combined with upper gingivobuccal sulcus incision offers excellent exposure of the zygoma-orbit complex, and could be a valid alternative to the bicoronal approach for osteotomy of malunioned zygoma.

Children who have had surgery involving the placement of an implant frequently undergo a subsequent surgery for hardware removal. The cosmesis of surgical scars following initial and subsequent surgeries is unpredictable. Scar incision (subsequent surgical incision through the initial scar) or excision (around the initial scar) is selected on the basis of the quality of the initial scar. The outcomes following these techniques have not been determined. This prospective, consecutive case series was designed to compare outcomes following surgical scar incision versus excision at the time of implant removal in children with cerebral palsy. Photographs of the scars were made preoperatively and at 6 and 12 months following implant removal and were graded for scar quality utilizing the modified Stony Brook Scar Evaluation Scale (SBSES). Parental assessment of scar appearance was performed at the same time points utilizing a visual analog cosmetic scale (VACS). The scars that were selected for incision had significantly worse SBSES scores at 6 and 12 months following the second surgery compared with preoperative values. However, parents' VACS scores of the incised scars, although worse at 6 months, were comparable with preoperative scores at 12 months. Scars that were selected for excision had significantly worse SBSES scores at 6 months but scores that were comparable with preoperative values at 12 months. VACS scores for the excised scars were comparable at the 3 time points. Surgical incisions that initially healed with good scar quality generally healed well (from the parents' perspective) following subsequent incision through the previous scar. Surgical incisions that initially healed with poor scar quality did not heal better following excision of the previous scar. In such situations, surgical excision of the existing scar should occur in conjunction with additional adjuvant therapies to improve cosmesis. Therapeutic Level II.

Surgical excision has been an effective treatment for gynaecomastia. Recently, there has been a shift from the open approach to minimally invasive techniques. In this report we describe our technique which includes endoscopic excision and/or liposuction of gynaecomastia via a single lateral chest wall incision. Between May 2007 and April 2010, a total of 12 gynaecomastia patients were treated with liposuction and/or endoscopic excision. Patients were divided into 3 groups: group I; liposuction only, group II; endoscopic excision plus liposuction and group III; endoscopic excision only. One 15 mm incision was made laterally at the anterior axillary line. A vacuum assisted liposuction removing the fatty tissue was performed. Then endoscopic excision of the remaining fibroglandular tissue was done under vision through the same incision. The parynchyma was then dissected into small pieces and pulled out. Group I had liposuction only (n = 4), group II had liposuction combined with endoscopic excision (n = 7) (58%) while group III had endoscopic excision only (n = 1). The mean operative time for liposuction and endoscopic excision was 58 min for each side. Mean hospital stay was 1.4 days. Postoperative complications included infection with abscess formation and one patient had seroma. Mean follow-up was 56 weeks. Eleven out of twelve patients (92%) were satisfied with their results. Long-term follow-up showed that results were stable over time, and no revisions were necessary. Endoscopic excision of gynaecomastia through a single lateral chest wall incision is a minimally invasive effective and safe technique for the management of gynaecomastia, with excellent aesthetic results and an acceptable complication rate.

To compare maternal outcomes after transection and after avoiding incision of the anterior placenta previa during cesarean delivery. In a retrospective study, records were reviewed for women who had anterior placenta previa and delivered by cesarean after 24 weeks of pregnancy at a tertiary center in Rouen, France. During period A (January 2000 to December 2006), the protocol was to systematically transect the placenta when it was unavoidable. During period B (January 2007 to December 2010), the technique was to avoid incision by circumventing the placenta and passing a hand around its margin. Logistic regression was used to identify independent risk factors associated with maternal transfusion of packed red blood cells. Eighty-four women were included (period A: n=43; period B: n=41). During period B, there was a reduction in frequency of intraoperative hemorrhage (>1000 mL) (P=0.02), intraoperative hemoglobin loss (P=0.005), and frequency of blood transfusion (P=0.02) as compared with period A. In multivariable analysis, period B was associated with a reduced risk of maternal transfusion (odds ratio 0.27; 95% confidence interval 0.09-0.82; P=0.02). Avoiding incision of the anterior placenta previa was found to reduce frequency of maternal blood transfusion during or after cesarean delivery.

Fisheries research involving surgical implantation of transmitters necessitates the use of methods that minimize transmitter loss and fish mortality and optimize healing of the incision. We evaluated the effects of three incision locations on transmitter loss, healing, survival, growth, and suture retention in juvenile Chinook salmon Oncorhynchus tshawytscha. The three incision locations were (1) on the linea alba (LA incision), (2) adjacent and parallel to the LA (muscle-cutting [MC] incision), and (3) extending from the LA towards the dorsum at a 45° angle, between the parallel lines of myomeres (muscle-sparing [MS] incision). A Juvenile Salmon Acoustic Telemetry System acoustic transmittermore » (0.44 g in air) and a passive integrated transponder tag (0.10 g in air) were implanted into each fish (total N = 936 fish). The fish were held at 12°C or 20°C and were examined weekly for 98 d. The progression of healing among incision locations and the variability in transmitter loss made it difficult to identify one incision location as the best choice. The LA incisions had a much smaller wound extent (area of visible subepidermal tissue) than MC and MS incisions during the first 28 d of the study. In both temperature treatments, apposition of incisions through day 14 was better for LA incisions than for MC and MS incisions. However, MC and MS incisions were less likely than LA incisions to reopen over time and thus were less likely to allow transmitter loss through the incision.« less

Does pilonidal abscess heal quicker with off-midline incision and drainage?

2011-06-01

No clinical trials have been done to guide the surgeon in the optimal technique of draining a pilonidal abscess. The aim of our study was to investigate whether the location of the incision influences wound healing. Electronic records from the surgical database at our 200-bed district general hospital were reviewed for operative technique (midline vs. lateral) for patients who underwent incision and drainage for acute pilonidal abscess between January 2003 and February 2010. These patients were admitted from the Emergency Department with a pilonidal abscess, underwent operative drainage, and returned for follow-up. The main outcome measure was wound healing time. Two hundred and forty-three pilonidal abscesses were drained, 134 with a lateral and 74 with a midline incision. All patients underwent simple longitudinal incision. No patient underwent de-roofing, marsupialisation, or closure. Forty-eight patients with midline drainage who returned for follow-up were matched for gender, age, and microbiology culture results with patients who underwent lateral drainage. Almost all were drained under general anesthesia with a median postoperative stay of 1 day. The overall length of follow-up was the same in both groups (P = 0.13). Abscesses that did not heal were followed-up for the same period of time irrespective of incision type (P = 0.48). Abscesses that healed after midline incision took approximately 3 weeks longer than those drained via a lateral incision (P = 0.02). Our study has limitations since it was a retrospective study that did not capture patients whose abscess drained spontaneously or were drained in the emergency department. Pilonidal abscess should be drained away from the midline.

Obstetric balloon for treatment of foreshortened vagina using the McIndoe technique.

PubMed

Rauktys, Aubrey; Parikh, Pranay; Harmanli, Oz

2015-01-01

When conservative options such as the use of vaginal dilators fail, the McIndoe technique may be used in the surgical treatment of a foreshortened vagina. The McIndoe procedure, an approach commonly used for the treatment of vaginal agenesis, requires a mold over which a skin graft is sutured and placed inside the vagina. In most surgical descriptions, this mold is made from non-sterile foam, condoms, or gloves. Because makeshift molds can no longer be used in operating rooms owing to strict regulations, alternative methods must be employed. The obstetric balloon is a good choice for use as a soft and adjustable vaginal mold for a modified McIndoe procedure because it is readily available as an approved device in hospitals that provide obstetric services. This technique was successfully employed in a 54-year-old woman to treat foreshortened vagina. An obstetric balloon can be used effectively as a mold for vaginal reconstruction with the McIndoe technique.

To explore the reason, key diagnosic point and therapeutic method of the incisions fat colliquation or infections at early stage after operation of lumbar disc herniation. From July 2007 to May 2012, clinical data of 11 patients with incision fat liquefaction or early infection after lumbar discectomy were retrospectively analyzed. There were 5 males and 6 females with an average age of 43.1 years, and the mean time of incisions fat colliquation or infection was 5 days and a half after operation. The main clinical features included local wound pain aggravating, fervescence, fresh seepage in the wound, and blood inflammatory index increased, etc. The wound could heal at the first treatment stage or not was an evaluation standard of curative effect. All patients were followed up with an average period of 21 months. The wounds of 10 cases healed at the first stage without recurrence and complications. In 1 case infected by staphylococcus aureus, distal part of the wound present local red, swelling and with wave motion at 2 months after operation, staphylococcus aureus infection was confirmed after puncture and bacterial culture, and 1 thrum was found after local incision. The wound healed after change dressings for 1 week, without recurrence after followed up for 13 months. Preventing the risk factors before operation, minimizing invasive technique during operation reasonable antibiotics application for the lumbar operation reguiring placement objects, and correctly handling with wound after operation could prevent and reduce the incidence of incisions fat liquefaction or infection after operation of lumbar disc herniation. For incision fat liquefaction or infection, early diagnosis, debridement, VSD negative pressure irrigation and drainage, to choosing sensitive antibiotics according to the results of drug sensitivity, may contribute to wound early healing and decrease complication.

This study proposes a new model to predict the reaction force that occurs in incisions during robot-assisted minimally invasive surgery. The reaction force is fed back to the manipulator by a magneto-rheological fluid (MRF) haptic master, which is featured by a bi-directional clutch actuator. The reaction force feedback provides similar sensations to laparotomy that cannot be provided by a conventional master for surgery. This advantage shortens the training period for robot-assisted minimally invasive surgery and can improve the accuracy of operations. The reaction force modeling of incisions can be utilized in a surgical simulator that provides a virtual reaction force. In this work, in order to model the reaction force during incisions, the energy aspect of the incision process is adopted and analyzed. Each mode of the incision process is classified by the tendency of the energy change, and modeled for realistic real-time application. The reaction force model uses actual reaction force information with three types of actual tissues: hard tissue, medium tissue, and soft tissue. This modeled force is realized by the MRF haptic master through an algorithm based on the position and velocity of a scalpel using two different control methods: an open-loop algorithm and a closed-loop algorithm. The reaction forces obtained from the proposed model are compared with a desired force in time domain.

Background: Transumbilical single incision laparoscopic surgery (SILS) offers excellent cosmetic results and may be associated with decreased postoperative pain, reduced need for analgesia, and thus accelerated recovery. Herein, we report the first transumbilical single incision laparoscopic pancreatectomy case in a patient who had renal cell cancer metastasis on her pancreatic corpus and tail. Methods: A 59-year-old female who had metastatic lesions on her pancreas underwent laparoscopic subtotal pancreatectomy through a 2-cm umbilical incision. Results: Single incision pancreatectomy was performed with a special port (SILS port) and articulated equipment. The procedure lasted 330 minutes. Estimated blood loss was 100mL. No perioperative complications occurred. The patient was discharged on the seventh postoperative day with a low-volume (20mL/day) pancreatic fistula that ceased spontaneously. Pathology result of the specimen was renal cell cancer metastases. Conclusion: This is the first reported SILS pancreatectomy case, demonstrating that even advanced surgical procedures can be performed using the SILS technique in well-experienced centers. Transumbilical single incision laparoscopic pancreatectomy is feasible and can be performed safely in experienced centers. SILS may improve cosmetic results and allow accelerated recovery for patients even with malignancy requiring advanced laparoscopic interventions. PMID:21605524

Epidermal cysts are cystic tumors lined with keratinized squamous layer and filled with keratin debris. Epidermal cysts may develop by implantation of surface epidermal layer into the dermis or subcutaneous tissue after trauma or surgical procedures. Cervix cancer spreads either directly or via the vascular and lymphatic systems. Distant skin metastasis of endometrium or cervix cancer is very rare. In this case report, a patient who had a history of cervix cancer operation 11 years ago and presented with a mass that mimicked incision line metastasis and was histopathologically diagnosed with epidermal cyst is presented.

Contemporary training in obstetrics and gynecology is aimed at the acquisition of a complex set of skills oriented to both the technical and personal aspects of patient care. The ability to create clinical simulations through virtual reality (VR) may facilitate the accomplishment of these goals. The purpose of this paper is 2-fold: (1) to review the circumstances and equipment in industry, science, and education in which VR has been successfully applied, and (2) to explore the possible role of VR for training in obstetrics and gynecology and to suggest innovative and unique approaches to enhancing this training. Qualitative assessment of the literature describing successful applications of VR in industry, law enforcement, military, and medicine from 1995 to 2000. Articles were identified through a computer-based search using Medline, Current Contents, and cross referencing bibliographies of articles identified through the search. One hundred and fifty-four articles were reviewed. This review of contemporary literature suggests that VR has been successfully used to simulate person-to-person interactions for training in psychiatry and the social sciences in a variety of circumstances by using real-time simulations of personal interactions, and to launch 3-dimensional trainers for surgical simulation. These successful applications and simulations suggest that this technology may be helpful and should be evaluated as an educational modality in obstetrics and gynecology in two areas: (1) counseling in circumstances ranging from routine preoperative informed consent to intervention in more acute circumstances such as domestic violence or rape, and (2) training in basic and advanced surgical skills for both medical students and residents. Virtual reality is an untested, but potentially useful, modality for training in obstetrics and gynecology. On the basis of successful applications in other nonmedical and medical areas, VR may have a role in teaching essential elements

Pre-operative prophylactic antibiotics may decrease the frequency of surgical site infection after appendectomy. However, the optimal timing for administration of pre-operative prophylactic antibiotics is unknown. The purpose of this study was to evaluate the effect of timing of prophylactic antibiotics on the frequency of surgical site infection after appendectomy. Medical records were reviewed retrospectively for 577 consecutive patients who had appendectomy for acute appendicitis from 2006 to 2009. Quality assurance guidelines for timing of prophylactic antibiotics before the skin incision were changed from 0 to 30 min before the skin incision (before June 2008) to 30 to 60 min before the skin incision (after June 2008). Surgical site infection occurred in 28 patients (4.9%). There was no difference in frequency of surgical site infection with different timing of pre-operative prophylactic antibiotic (pre-operative time 0 to 30 min: 9 infections [3.6%]; 31 to 60 min: 13 infections [5.4%]; 61 to 120 min: 5 infections [7.0%]; >120 min: 1 infection [6.6%]). Multivariable analysis showed that surgical site infection was associated significantly with medical comorbidity but not perforated appendicitis. The frequency of surgical site infection was independent of timing of preoperative prophylactic antibiotics but was associated with the presence of medical comorbidity.

Gynecomastia describes a benign increase of the mammary gland in men. When medical treatment fails, symptoms and psychological alterations persist. Subdermal mastectomy is the definitive treatment and can be achieved by different incisions, each with potential complications. We undertook this study to present clinical characteristics of 11 patients with gynecomastia and the results obtained with subdermal mastectomy by means of external periareolar incision. A descriptive cohort study in male patients with gynecomastia was carried out in a third-level medical care hospital. Patients were treated with subdermal mastectomy by means of external periareolar incision. There were 11 male patients with an average age of 19 years (range: 11-60 years), 3 patients (27.2%) with bilateral gynecomastia and 8 patients (72.7%) with unilateral gynecomastia. Average time of evolution was 22 months (range: 16-48 months), 9 patients (81.8%) reported pain, 11 patients (100%) reported psychological alterations with cutaneous alteration, 11 patients (100%) had normal secondary sexual characteristics, 1 patient (9%) had supernumerary nipple development, and 11 patients (100%) had well-defined lesions. According to Simon's classification: seven patients (63.6%) were classified as grade 1, three patients (27.2%) as grade 2 and one patient (9.09%) as grade 3. Each patient had a subdermal mastectomy with external periareolar incision, 11 patients (100%) had a histopathological report of gynecomastia; 1 patient (9.09%) displayed keloid healing and none displayed complications inherent to the surgical procedure. Mastectomy by means of external periareolar incision is useful in the treatment of gynecomastia.

In this case report, we discuss single-incision laparoscopic cecectomy for low-grade appendiceal neoplasm after laparoscopic anterior resection for rectal cancer. The optimal surgical therapy for low-grade appendiceal neoplasm is controversial; currently, the options include appendectomy, cecectomy, right hemicolectomy, and open or laparoscopic surgery. Due to the risk of pseudomyxoma peritonei, complete resection without rupture is necessary. We have encountered 5 cases of low-grade appendiceal neoplasm and all 5 patients had no lymph node metastasis. We chose the appendectomy or cecectomy without lymph node dissection if preoperative imaging studies did not suspect malignancy. In the present case, we performed cecectomy without lymph node dissection by single-incision laparoscopic surgery (SILS), which is reported to be a reduced port surgery associated with decreased invasiveness and patient stress compared with conventional laparoscopic surgery. We are confident that SILS is a feasible alternative to traditional surgical procedures for borderline tumors, such as low-grade appendiceal neoplasms. PMID:24868331

Laparoscopic Roux-en-Y gastric bypass is the gold standard bariatric procedure. Typically, the procedure necessitates five to seven small skin incisions for trocar placement. The senior author (AA Saber) has developed a three-trocar approach for laparoscopic Roux-en-Y gastric bypass. Sixteen patients underwent triple-incision laparoscopic Roux-en-Y gastric bypass between May 2009 and August 2009. The same surgeon performed all surgical interventions. The umbilicus was the main point of entry for all patients and the same operative technique and perioperative protocol were used in all patients. A total of sixteen triple-incision laparoscopic Roux-en-Y gastric bypasses were performed. The procedures were successfully performed in all patients. Mean operating time was 145.4 min. None of the patients required conversion to an open procedure. There were no mortalities or post-operative technical complications noted during the immediate post-operative period. Three trocar laparoscopic Roux-en-Y gastric bypass is safe, technically feasible and reproducible. This technique may be considered a "precursor" to single-incision laparoscopic Roux-en-Y gastric bypass. Copyright 2009 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.

The integration of simulation into residency programs has been slower in obstetrics and gynaecology than in other surgical specialties. The goal of this study was to evaluate the current use of simulation in obstetrics and gynaecology residency programs in Canada. A 19-question survey was developed and distributed to all 16 active and accredited obstetrics and gynaecology residency programs in Canada. The survey was sent to program directors initially, but on occasion was redirected to other faculty members involved in resident education or to senior residents. Survey responses were collected over an 18-month period. Twelve programs responded to the survey (11 complete responses). Eleven programs (92%) reported introducing an obstetrics and gynaecology simulation curriculum into their residency education. All respondents (100%) had access to a simulation centre. Simulation was used to teach various obstetrical and gynaecological skills using different simulation modalities. Barriers to simulation integration were primarily the costs of equipment and space and the need to ensure dedicated time for residents and educators. The majority of programs indicated that it was a priority for them to enhance their simulation curriculum and transition to competency-based resident assessment. Simulation training has increased in obstetrics and gynaecology residency programs. The development of formal simulation curricula for use in obstetrics and gynaecology resident education is in early development. A standardized national simulation curriculum would help facilitate the integration of simulation into obstetrics and gynaecology resident education and aid in the shift to competency-based resident assessment. Obstetrics and gynaecology residency programs need national collaboration (between centres and specialties) to develop a standardized simulation curriculum for use in obstetrics and gynaecology residency programs in Canada.

This study aims to describe patient demographics, visual and surgical outcomes of a cohort undergoing small incision cataract surgery at a Pacific regional ophthalmic training facility. This is a prospective, longitudinal study conducted at the Pacific Eye Institute, Fiji. One hundred fifty-six patients underwent small incision cataract surgery. Preoperatively, a complete ophthalmic examination, including pachymetry and macular optical coherence tomography performed by two independent investigators. Temporal small incision cataract surgery with intraocular lens insertion was performed by ophthalmologists, and trainee ophthalmologists. Follow-up occurred at day one, four weeks and 3 months. Patient characteristics, visual outcomes including surgically induced astigmatism and complications. Ninety-one per cent (142/156) attended 3-month follow-up with median age 63 years (range 19-82), 52% female (81/156) and 58% (90/156) Fijian ethnicity. In 37% (57/156), the contralateral eye was pseudophakic. Mean preoperative best spectacle-corrected visual acuity was logMAR 1.44 (6/165). At 3 months, 74% (105/142) achieved ≥6/18 unaided vision (94% [133/142] best spectacle-corrected visual acuity). Mean postoperative spherical equivalent was -0.78 (SD 0.95) D and mean surgically induced astigmatism 1.04 (0.57) D. Complications included posterior capsular rupture with vitreous loss (4% [6/156]), optical coherence tomography confirmed macular oedema (8% [12/152] at 4 weeks), significant posterior capsular opacity (23% [31/136]) and >5% increase in preoperative pachymetry (1% [1/142]) at 3 months. Reduction in preoperative best spectacle-corrected visual acuity occurred in 2% (3/142). No cases of endophthalmitis. Small incision cataract surgery provided to a regional population is effective with 94% achieving the World Health Organisation's definition of 'Good Vision' (≥6/18).

Introduction: New technologies in dental practice, such as laser, have enabled new strategies to be established in dental education. The aim of this study was to analyze the difficulties that dental students encountered with performing surgical incisions using Er:YAG laser (LE), and the morphology of these incisions. Material and Methods: Sixteen undergraduate dental students and ten dental professionals (DP) enrolled at The Master of Science Program in Laser Dentistry were asked to perform 15 incisions using an LE and 15 with a conventional scalpel. The incisions were compared, based on the shape factor (relation between area and perimeter), which was obtained by a digital image system and by a morphometry software. Data was submitted to statistical analysis of variance (p 0.05). Results: Considering the incisions performed by scalpel, DP showed statistically significant differences (p < 0.01) in relation to control group (CG). Considering the LE, all groups showed significant differences (p<0.0001) in relation to CG, especially the DP group. The main laser technical failures were performing an incision that was not in a straight line, without defined borders, using an inconstant cutting speed, and absence of suction and water jet appliances. None of the groups performed adequate incisions using LE. Conclusion: Greater emphasis is required in relating laser therapy practice to the physical properties of laser, particularly for dental professionals that specialize in laser.

Temperature-controlled tissue laser soldering is an innovative sutureless technique awaiting only solid experimental data to become the gold-standard surgical procedure for incision closure. The goals of the current study were: (1) to define the optimal laser soldering conditions, (2) to explore the immediate skin reparative healing events after sealing the wound, and (3) to determine the long-term trajectory of skin wound healing. Skin incisions were generated over rabbit dorsa and were closed using different wound-closure interventions, in three groups: (a) closure, using a temperature-controlled infrared fiberoptic CO2 laser system, employing 47% bovine serum albumin as a solder; (b) wound closure by cyanoacrylate glues; and (c) wound closure by sutures. The reparative outcomes were evaluated macroscopically and microscopically, employing semi-quantitative grading indices. Laser soldering of incisions at T = 65 degrees C emerged as the optimal method achieving immediate wound sealing. This in turn induced accelerated reparative events characterized by a reduced inflammatory reaction, followed by minimal scarring and leading to a fine quality healing. Temperature-controlled laser soldering offers an accelerated wound reparative process with numerous advantages over the conventional methods. Further investigations may reveal additional benefits in the spectrum of advantages that this innovative surgical technology has to offer. This can introduce new scientific insight that will pave the way for clinical use.

The aim of the study was to compare the clinical outcomes of a 1.8 mm, 2.2 mm, and 2.75 mm microcoaxial cataract surgery system. METHODS. In this retrospective study, 129 eyes of 129 patients were included. Patients underwent phacoemulsification using a Stellaris system or an Infiniti system. The incision size was 1.8 mm, 2.2 mm, or 2.75 mm, respectively. Subjects were examined before surgery and 4 weeks after. The surgically induced astigmatism (SIA) was examined. The SIA in the 1.8 mm group was statistically lower compared to the 2.2 mm group (p=0.046) and the 2.75 mm group (p=0.017). There was no significant difference between the 2.2 mm group and the 2.75 mm group. With the use of appropriate support systems, 1.8 mm incisions appear to result in less SIA than 2.2 mm and 2.75 mm incisions. Advantages may arise from this, especially in the implantation of aspheric, toric, or multifocal lenses.

The perceived difficulty of steps of manual small incision cataract surgery among trainees in rural China was assessed. Cohort study. Fifty-two trainees at the end of a manual small incision cataract surgery training programme. Participants rated the difficulty of 14 surgical steps using a 5-point scale, 1 (very easy) to 5 (very difficult). Demographic and professional information was recorded for trainees. Mean ratings for surgical steps. Questionnaires were completed by 49 trainees (94.2%, median age 38 years, 8 [16.3%] women). Twenty six (53.1%) had performed ≤50 independent cataract surgeries prior to training. Trainees rated cortical aspiration (mean score ± standard deviation = 3.10 ± 1.14) the most difficult step, followed by wound construction (2.76 ± 1.08), nuclear prolapse into the anterior chamber (2.74 ± 1.23) and lens delivery (2.51 ± 1.08). Draping the surgical field (1.06 ± 0.242), anaesthetic block administration (1.14 ± 0.354) and thermal coagulation (1.18 ± 0.441) were rated easiest. In regression models, the score for cortical aspiration was significantly inversely associated with performing >50 independent manual small incision cataract surgery surgeries during training (P = 0.01), but not with age, gender, years of experience in an eye department or total number of cataract surgeries performed prior to training. Cortical aspiration, wound construction and nuclear prolapse pose the greatest challenge for trainees learning manual small incision cataract surgery, and should receive emphasis during training. Number of cases performed is the strongest predictor of perceived difficulty of key steps. © 2013 The Authors.

Open reduction through an intercartilaginous incision was useful for treating delayed-diagnosed nasal bone fractures because it resulted in a successful outcome with minimal complications. Nasal bone fractures are generally managed with closed reduction, which is usually inadequate and results in airway obstruction with a delayed diagnosis of nasal bone fracture when bone healing and fibrotic adhesions around the bone fragment have progressed. This study investigated the surgical outcome of open reduction through an intercartilaginous incision for delayed-diagnosis nasal bone fractures. The study enrolled 18 patients who underwent open reduction through an intercartilaginous incision to correct delayed-diagnosis nasal bone fractures. Three independent otorhinolaryngologists evaluated the outcomes 4-35 months (average 12.7 months) postoperatively as excellent, fair or poor. The time from injury to surgery was 11-39 days (20-39 days in adults and 11-30 days in children). The 18 cases included 16 primary repairs and two revisions. A Kirschner wire was inserted in six (33.3%) patients who had unstable reduced nasal bones. Postoperatively, l5 (83%) patients had excellent results, two (11%) had fair, and one (6%) had a poor outcome. No patient experienced any complication.

With the advancement of laparoscopic devices and surgical technology, the era of minimal invasive surgery has progressed to reduced-port surgery, and finally to single-incision laparoscopic surgery (SILS). Several reports show successful application of SILS to various types of bariatric surgery. Oftentimes, this requires a skilled and experienced scopist to perform the procedure. To overcome the technical difficulties of single-incision Roux-en-Y gastric bypass, a manual scope holder was used instead of an assistant scopist, greatly stabilizing the field of view. This allows the surgery to be performed at any time without being influenced by the need of a highly experienced scopist. In this report, we describe in detail the world's first solo single-incision laparoscopic resectional Roux-en-Y gastric bypass.

Reductions in the size of acoustic transmitters implanted in migrating juvenile salmonids have resulted in the use of a shorter incision-one that may warrant only a single suture for closure. However, it is not known whether a single suture will sufficiently hold the incision closed when fish are decompressed and when outward pressure is placed on the surgical site during turbine passage through hydroelectric dams. The objective of this study was to evaluate the effectiveness of single-suture incision closures on five response variables in juvenile Chinook salmon Oncorhynchus tshawytscha that were subjected to simulated turbine passage. An acoustic transmitter (0.43more » g in air) and a passive integrated transponder tag (0.10 g in air) were implanted in each fish; the 6-mm incisions were closed with either one suture or two sutures. After exposure to simulated turbine passage, none of the fish exhibited expulsion of transmitters. In addition, the percentage of fish with suture tearing, incision tearing, or mortal injury did not differ between treatments. Expulsion of viscera through the incision was higher among fish that received one suture (12%) than among fish that received two sutures (1%). The higher incidence of visceral expulsion through single-suture incisions warrants concern. Consequently, for cases in which tagged juvenile salmonidsmay be exposed to turbine passage, we do not recommend the use of one suture to close 6-mm incisions associated with acoustic transmitter implantation.« less

The learning curve for performing living donor hemiliver procurement (LDHP) via small upper midline incision (UMI) has not been determined. Living donors (n=101) who underwent LDHP via UMI were included to investigate the learning curve using cumulative sum analysis. The cumulative sum analysis showed that nine cases for right lobe (case #23) and 19 cases for left lobe (case #32 in the whole series) are needed for stable and acceptable surgical outcomes in LDHP via UMI. The established phase (n=69, since case #33) had a significantly shorter operative time, a smaller incision size, and less blood loss than the previous learning phase (n=32, serial case number up to the last 19th left lobe case). Multivariate analysis showed that the learning phase, high body mass index ≥25 kg/m 2 , and left lobe graft procurement are the factors associated with surgical events including operative blood loss ≥400 mL, operative time ≥300 minutes, or surgical complications ≥Clavien-Dindo grade II. There is an obvious learning curve in performing LDHP via UMI, and 32 cases including both 19 cases for left lobe and nine cases for right lobe are needed for having stable and acceptable surgical outcomes. © 2016 John Wiley & Sons A/S.

Although single-incision laparoscopic cholecystectomy is now widely performed in patients with cholecystitis, some cases require an additional port to complete the procedure. In this study, we focused on risk factor of additional port in this surgery. We performed single-incision cholecystectomy in 75 patients with acute cholecystitis or after cholecystitis between 2010 and 2014 at Gunma University Hospital. Surgical indications followed the TG13 guidelines. Our standard procedure for single-incision cholecystectomy routinely uses two needlescopic devices. We used logistic regression analysis to identify the risk factors associated with use of an additional full-size port (5 or 10 mm). Surgical outcome was acceptable without biliary injury. Nine patients (12.0%) required an additional port, and one patient (1.3%) required conversion to open cholecystectomy because of severe adhesions around the cystic duct and common bile duct. In multivariate analysis, high C-reactive protein (CRP) values (>7.0 mg/dl) during cholecystitis attacks were significantly correlated with the need for an additional port (P = 0.009), with a sensitivity of 55.6%, specificity of 98.5%, and accuracy of 93.3%. This study indicated that the severe inflammation indicated by high CRP values during cholecystitis attacks predicts the need for an additional port. J. Med. Invest. 64: 245-249, August, 2017.

Reductions in the size of acoustic transmitters implanted in migrating juvenile salmonids have resulted in the ability to make shorter incisions that may warrant using only a single suture for closure. However, it is not known if one suture will sufficiently hold the incision closed, particularly when outward pressure is placed on the surgical site such as when migrating fish experience pressure changes associated with passage at hydroelectric dams. The objective of this research was to evaluate the effectiveness of single-suture incision closures on juvenile Chinook salmon (Oncorhynchus tshawytscha). Juvenile Chinook salmon were surgically implanted with a 2012 Juvenile Salmonmore » Acoustic Telemetry System (JSATS) transmitter (0.30 g) and a passive integrated transponder tag (0.10 g) and incisions were closed with either one suture or two sutures. Mortality and tag retention were monitored and fish were examined after 7 and 14 days to evaluate tissue responses. In a separate experiment, surgically implanted fish were exposed to simulated turbine passage and then examined for expulsion of transmitters, expulsion of viscera through the incision, and mortal injury. With incisions closed using a single suture, there was no mortality or tag loss and similar or reduced tissue reaction compared to incisions closed with two sutures. Further, surgery time was significantly reduced when one suture was used, which leads to less handling and reduced stress. No tags were expelled during pressure scenarios and expulsion of viscera only occurred in two non-mortally injured fish (5%) with single sutures that were also exposed to very high pressure changes. No viscera expulsion was present in fish exposed to pressure scenarios likely representative of hydroturbine passage at many Columbia River dams (e.g. <2.7 ratio of pressure change; an acclimation pressure of 146.2 absolute kpa and a lowest exposure pressure of ~ 53.3 absolute kpa). Based on these results, we recommend the

Overview of surgical scar prevention and management.

Management of incisional scar is intimately connected to stages of wound healing. The management of an elective surgery patient begins with a thorough informed consent process in which the patient is made aware of personal and clinical circumstances that cannot be modified, such as age, ethnicity, and previous history of hypertrophic scars. In scar prevention, the single most important modifiable factor is wound tension during the proliferative and remodeling phases, and this is determined by the choice of incision design. Traditional incisions most often follow relaxed skin tension lines, but no such lines exist in high surface tension areas. If such incisions are unavoidable, the patient must be informed of this ahead of time. The management of a surgical incision does not end when the sutures are removed. Surgical scar care should be continued for one year. Patient participation is paramount in obtaining the optimal outcome. Postoperative visits should screen for signs of scar hypertrophy and has a dual purpose of continued patient education and reinforcement of proper care. Early intervention is a key to control hyperplastic response. Hypertrophic scars that do not improve by 6 months are keloids and should be managed aggressively with intralesional steroid injections and alternate modalities.

To compare the classical double-layer uterine closure to a double-layer purse-string uterine closure (Turan technique) in cesarean section regarding short- and long-term results. Patients were randomized into either the double-layer purse-string uterine closure arm (study group, 84 patients) or the classical double-layer uterine closure arm (control group, 84 patients). For short-term comparison, a detailed transvaginal ultrasound examination was planned in all patients 6 weeks after the operation and a wedge-shaped defect in the uterine incision scar was accepted as uterine scar defect and recorded. For the long-term comparison, subsequent pregnancies of these patients were followed up for any complication. The number of patients with ultrasonographically visible uterine scar defect was 12 (23.5% of all scar defects) in the study group whereas it was 39 (76.5% of all scar defects) in the control group (P < 0.001, χ(2) = 15.42). Demographic data, operation time, hospitalization time, preoperative and postoperative hemoglobin values were not significantly different between the groups. During the 2-year of the follow-up period, five patients in the study group and six patients in the control group became pregnant again. No complication during their pregnancies and second cesarean operation were encountered. With the Turan technique, the uterine incision length becomes shorter, and the frequency of uterine scar defect is lower regarding short-term results. More data is needed for long-term results.

Purpose We hypothesized that the elastic nature of the choroid leads to tissue contraction following a full-thickness, sharp incision. Furthermore, we sought to quantify, measure, and compare tissue contraction in ex vivo porcine globes and human globes of various ages using predetermined variables. Method A full-thickness, ex vivo choroidal incision was performed in either pig (n = 97) or human (n = 30) specimens. Variables included trephine diameter (1.5, 2.0, or 2.5 mm) versus a straight surgical blade, and temperature (1.7 °–4.4° vs. 36.6°F). Central centripetal and surround centrifugal tissue contractions were measured. Mean percentage tissue contraction was assessed as a ratio of trephine diameter to final tissue contraction measured immediately following each incision using a standardized device. Results For trephination in pig specimens, centripetal contraction ranged from 38% to 50% with a mean of 44%. Centrifugal contraction was approximately 15%. Human choroidal contraction was 39% and 15%, respectively, with a statistically significant inverse relationship to age (R2 = 0.35, P ≤ 0.01). Asymmetric contraction was noted when incisions were closer to choroidal attachment sites to the sclera, such as near vortex ampullae. Linear incisions resulted in contraction that correlated with incision length (R2 = 0.35, P ≤ 0.001). Conclusions A full-thickness choroidal incision results in significant tissue contraction. For circular incisions, the centripetal contraction approaches 50% of the original incision size. For linear incisions, the contraction corresponds directly with incision length. In human specimens, there is less contraction with advancing age. Translational Relevance Our findings have clinical relevance for choroidal biopsy, traumatic injury, and choroidal translocation surgery. PMID:29134136

Cyclooxygenase (COX)-2 inhibitors are widely used for postoperative pain control in clinical practice. However, it is unknown whether spinal sensitization is involved in the analgesic effects of COX-2 inhibitors on surgical pain. Extracellular signal-regulated kinase (ERK) in the spinal cord is implicated in various types of pain, including surgical pain. The present study investigated the role of spinal ERK signaling in the analgesic effect of the COX-2 inhibitor parecoxib on surgical pain. Surgical pain was produced in rats by surgical incision of the hind paw. Phosphorylated (p)-ERK1/2 expression was determined by immunohistochemistry. Pain hypersensitivity was evaluated by measuring the paw withdrawal threshold using the von Frey test. The selective COX-2 inhibitor parecoxib was delivered 20 min before or 20 min after the incision by intraperitoneal injection. Pretreatment with parecoxib markedly attenuated the pain hypersensitivity induced by incision. However, post-treatment with parecoxib produced minimal analgesic effects. Parecoxib inhibited the increase in spinal p-ERK expression following surgical incision. The present study thus suggests that the COX-2 inhibitor parecoxib exerts its analgesic effect on surgical pain through the inhibition of neuronal ERK activation in the spinal cord. COX-2 inhibitor delivery prior to surgery has more potent analgesic effects, suggesting the advantage of preventive analgesia for post-operative pain control.

To compare the electrocautery incision with scalpel incision in patients undergoing abdominal surgery using a midline incision with respect to incision time, blood loss during incision, postoperative incision site pain and wound infection. Patients undergoing midline abdominal surgery were randomized into electrocautery and scalpel groups. The incision dimensions, incision time and blood loss during incision were noted intraoperatively. Postoperative pain and wound infection were recorded on every postoperative day for one week. 41 patients in each of the two groups were analyzed. Gender and age distribution was similar in both the groups. The mean incision time per unit wound area in the electrocautery group and scalpel group was 9.40 ± 3.37 s/cm(2) and 9.07 ± 3.40 s/cm(2) (p = 0.87) respectively. The mean blood loss per unit wound area was significantly lower in the electrocautery group at 6.46 ± 3.94 ml when compared to that of 23.40 ± 15.28 ml in the scalpel group (p= < 0.0001, CI = 11.97-21.89). There was no significant difference in pain on any of the postoperative days between the two groups and there was no significant difference in the wound infection rates between the electrocautery and scalpel groups (14.63% vs. 12.19%; p = 0.347). With a comparable Postoperative incision site pain, wound infection rate and significantly lower blood loss with the equal time taken for the incision, electrocautery can be considered safe and effective in making skin incision in midline laparotomy compared to scalpel incision.

The aim of this study was to review the typical factors related to physician's liability in obstetrics and gynecology departments, as compared to those in internal medicine and surgery, regarding a breach of the duty to explain. This study involved analyzing 366 medical litigation case reports from 1990 through 2008 where the duty to explain was disputed. We examined relationships between patients, physicians, variables related to physician's explanations, and physician's breach of the duty to explain by comparing mean values and percentages in obstetrics and gynecology, internal medicine, and surgical departments with the t-test and χ(2) test. When we compared the reasons for decisions in cases where the patient won, we found that the percentage of cases in which the patient's claim was recognized was the highest for both physician negligence, including errors of judgment and procedural mistakes, and breach of the duty to explain, in obstetrics and gynecology departments; breach of the duty to explain alone in internal medicine departments; and mistakes in medical procedures alone in surgical departments (p = 0.008). When comparing patients, the rate of death was significantly higher than that of other outcomes in precedents where a breach of the duty to explain was acknowledged (p = 0.046). The proportion of cases involving obstetrics and gynecology departments, in which care was claimed to be substandard at the time of treatment, and that were not argued as breach of a duty to explain, was significantly higher than those of other evaluated departments (p <0.001). However, internal medicine and surgical departments were very similar in this context. In obstetrics and gynecology departments, the proportion of cases in which it had been conceded that the duty to explain had been breached when seeking patient approval (or not) was significantly higher than in other departments (p = 0.002). It is important for physicians working in obstetrics and gynecology

To evaluate the change and difference in the corneal surface, incision, and handpiece temperatures during longitudinal and torsional ultrasound (US) phacoemulsification with standard incisions (2.75 mm) and microincisions (2.20 mm) and the thermal effect on wounds. Department of Ophthalmology, Duke University, Durham, North Carolina, USA. In this prospective study, human cadaver eyes had simulated phacoemulsification. Group 1 had a 2.75 mm incision with 100% longitudinal US; Group 2, a 2.20 mm incision with 100% longitudinal US; Group 3, a 2.75 mm incision with 100% torsional US; and Group 4, a 2.20 mm incision with 100% torsional US. During phacoemulsification, the corneal incision was evaluated by surgical microscopy and scanning electron microscopy (SEM) and images of the corneal surface, incision, and handpiece were captured with an infrared camera. Twelve eyes (3 each group) were evaluated. The maximum incision temperature was higher in the longitudinal groups than in the torsional groups. With the same US modality, the maximum microincision temperature was higher than the maximum standard incision temperature. After application of full power for 40 seconds, wound burn was observed in all eyes in the longitudinal groups and no eyes in the torsional groups. On SEM, there was more extensive loss of Descemet membrane in the longitudinal groups than in the torsional groups. Incision temperature was influenced by US modality and was significantly lower with torsional US than with longitudinal US. Using torsional US with smaller incisions may decrease the risk for wound burn in eyes with denser cataracts. (c) 2010 ASCRS and ESCRS. Published by Elsevier Inc. All rights reserved.

Strategies to reduce blood product utilization in obstetric practice.

Neb, Holger; Zacharowski, Kai; Meybohm, Patrick

Patient blood management (PBM) aims to improve patient outcome and safety by reducing the number of unnecessary RBC transfusions and vitalizing patient-specific anemia reserves. Although PBM is increasingly recognized as best clinical practice in elective surgery, implementation of PBM is restrained in the setting of obstetrics. This review summarizes recent findings to reduce blood product utilization in obstetric practice. PBM-related evidence-based benefits should be urgently adopted in the field of obstetric medicine. Intravenous iron can be considered a safe, effective strategy to replenish iron stores and to correct both pregnancy-related and hemorrhage-related iron deficiency anemia. In addition to surgical techniques and the use of uterotonics, recent findings support early administration of tranexamic acid, fibrinogen and a coagulation factor concentrate-based, viscoelastically guided practice in case of peripartum hemorrhage to manage coagulopathy. In patients with cesarean section, autologous red cell blood salvage may reduce blood product utilization, although its use in this setting is controversial. Implementation of PBM in obstetric practice offers large potential to reduce blood loss and transfusion requirements of allogeneic blood products, even though large clinical trials are lacking in this specific field. Intravenous iron supplementation may be suggested to increase peripartum hemoglobin levels. Additionally, tranexamic acid and point-of-care-guided supplementation of coagulation factors are potent methods to reduce unnecessary blood loss and blood transfusions in obstetrics.

To report the clinical features and outcomes of linear gastrointestinal incisions closed with skin staples in dogs. Historical cohort study. 333 client-owned dogs. Medical records from 1 private referral hospital were searched for dogs that underwent gastrointestinal surgery between November 1999 and October 2015. Cases were included if skin staplers were used to close linear gastrointestinal incisions. Information regarding preoperative, surgical, and postoperative factors was collected. Complications were diagnosed in 8 of 245 (3.27%) dogs, including 3 of 245 (1.22%) dogs that died or were euthanized, 3 of 245 (1.22%) dogs with incisional dehiscence, and 2 of 245 (0.81%) dogs with attachment of a linear foreign body to the staples at the intestinal lumen. Dehiscence was noted at the enterotomy sites in 3 dogs at a mean time of 44 hours after surgery (SD ± 6.93). Two dogs presented with another linear foreign body that was attached to the staples in the intestinal lumen at postoperative days 24 and 42. The risk factors associated with incisional dehiscence included multiple gastrointestinal incisions performed in 1 surgery (χ 2 , P < .001) and the presence of a linear foreign body (χ 2 , P = .02253). No associations were detected between dogs' age, sex, weight, surgery time, indication for surgical intervention, surgery location in the gastrointestinal tract, or surgeon experience and incisional dehiscence. Skin staplers provide safe and effective closure of gastrotomies, enterotomies, and colonotomies in dogs. This method is reliable, efficient, and affordable in the hands of veterinary surgeons with varying skill levels. © 2017 The American College of Veterinary Surgeons.

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

Climatic control of bedrock river incision.

Bedrock river incision drives the development of much of Earth's surface topography, and thereby shapes the structure of mountain belts and modulates Earth's habitability through its effects on soil erosion, nutrient fluxes and global climate. Although it has long been expected that river incision rates should depend strongly on precipitation rates, quantifying the effects of precipitation rates on bedrock river incision rates has proved difficult, partly because river incision rates are difficult to measure and partly because non-climatic factors can obscure climatic effects at sites where river incision rates have been measured. Here we present measurements of river incision rates across one of Earth's steepest rainfall gradients, which show that precipitation rates do indeed influence long-term bedrock river incision rates. We apply a widely used empirical law for bedrock river incision to a series of rivers on the Hawaiian island of Kaua'i, where mean annual precipitation ranges from 0.5 metres to 9.5 metres (ref. 12)-over 70 per cent of the global range-and river incision rates averaged over millions of years can be inferred from the depth of river canyons and the age of the volcanic bedrock. Both a time-averaged analysis and numerical modelling of transient river incision reveal that the long-term efficiency of bedrock river incision across Kaua'i is positively correlated with upstream-averaged mean annual precipitation rates. We provide theoretical context for this result by demonstrating that our measurements are consistent with a linear dependence of river incision rates on stream power, the rate of energy expenditure by the flow on the riverbed. These observations provide rare empirical evidence for the long-proposed coupling between climate and river incision, suggesting that previously proposed feedbacks among topography, climate and tectonics may occur.

Chronic stress has been reported to increase basal pain sensitivity and/or exacerbate existing persistent pain. However, most surgical patients have normal physiological and psychological health status such as normal pain perception before surgery although they do experience short-term stress during pre- and post-operative periods. Whether or not this short-term stress affects persistent postsurgical pain is unclear. In this study, we showed that pre- or post-surgical exposure to immobilization 6 h daily for three consecutive days did not change basal responses to mechanical, thermal, or cold stimuli or peak levels of incision-induced hypersensitivity to these stimuli; however, immobilization did prolong the duration of incision-induced hypersensitivity in both male and female rats. These phenomena were also observed in post-surgical exposure to forced swimming 25 min daily for 3 consecutive days. Short-term stress induced by immobilization was demonstrated by an elevation in the level of serum corticosterone, an increase in swim immobility, and a decrease in sucrose consumption. Blocking this short-term stress via intrathecal administration of a selective glucocorticoid receptor antagonist, RU38486, or bilateral adrenalectomy significantly attenuated the prolongation of incision-induced hypersensitivity to mechanical, thermal, and cold stimuli. Our results indicate that short-term stress during the pre- or post-operative period delays postoperative pain recovery although it does not affect basal pain perception. Prevention of short-term stress may facilitate patients' recovery from postoperative pain.

The rhytidectomy approach for parotidectomy allows the incision to be hidden, and post-operative scarring minimised. Furthermore, separate elevation of the Superficial Musculo-Aponeurotic System (SMAS) reduces the incidence of Frey's syndrome, and provides vascularized soft tissue for contour reconstruction. The technique has gained popularity particularly with plastic surgeons, but concerns persist that with this approach, particularly with lesions located anteriorly, access to the gland may be inadequate, and facial nerve identification may be compromised. We undertook an anatomical study to quantitatively compare the surgical access achieved using the facelift approach with the conventional Blair incision, by comparing the distances between the parotid edge and the retracted flaps. Despite reduced tissue elasticity due to formaldehyde fixation, it proved possible to demonstrate all regions of the parotid gland to the operating surgeon with either approach. There were no significant differences in the distance between the parotid edge and the retracted skin flaps (P > 0.1; paired t-test). The facelift approach provides at least equal access to all regions of the parotid gland when compared to a Blair's incision. It is a superior approach aesthetically and its more widespread use in parotid surgery is advocated.

Medical education commenced a century ago in 1905. In 1922, the Department of Midwifery and Gynaecology was established. This was renamed the Department of Obstetrics in 1951. Medical undergraduate curriculum in Obstetrics and Gynaecology has evolved and undergone radical changes. From a compulsory 11-week residential posting in Kandang Kerbau Hospital, medical students are now only expected to be resident when they are scheduled for night duties. Having been an examination subject by itself in the Final MBBS Examination, Obstetrics and Gynaecology has in the latest revised undergraduate medical curriculum been incorporated into the Surgical tract and has ceased to be evaluated as a subject on its own. In this review, the establishment of postgraduate training in Obstetrics and Gynaecology is traced over the last 50 years and the important changes over the years are described. The first local Master of Medicine (Obstetrics and Gynaecology) was awarded in 1971. Currently, the specialist training for Obstetrics and Gynaecology in Singapore spans a period of 6 years, comprising 3 years of basic structural training and 3 years of advanced structural training. Over the years, the Department of Obstetrics and Gynaecology, National University of Singapore, has played a pivotal role in the teaching of clinical and laboratory research. This has added substantially to Singapore's efforts to become a world-class knowledge hub, especially in the areas of relevance to Obstetrics and Gynaecology.

To explore the feasibility, safety, and preliminary technical experience of single incision plus one port laparoscopic total gastrectomy combined with π-shaped esophagojejunal anastomosis (SILT-π) in the surgical treatment of gastric cancer. Clinical data of 5 gastric cancer patients undergoing SILT-π operation at the Department of General Surgery, The Second Affiliated Hospital of the Army Medical University from August to October 2017 were retrospectively analyzed. A 2.5-3.0 cm incision around the umbilicus was made for placing the gloveport as the passage for the lens, and the instruments of the surgeon and the assistant. Another operative port was placed in the left upper quadrant with a 12-mm Trocar for the passage of the energy device, the endoscopic cutting closure, as well as the postoperative drainage tube. A D2 lymph node (LNs) dissection was regularly conducted. After the abdominal esophagus was routinely mobilized, a side-to-side esophagus-jejunum anastomosis was made through a gastric pre-pulling esophagojejunal π-shaped anastomosis. The transection was then performed with a ligation on the cardia (or esophagus above the upper margin of the tumor) using a sterilized hemp rope in order to better expose the abdominal esophagus. Throughout the course of reconstruction, the ligature rope was held by the assistant to hold down the esophagus to allow easier esophagojejunal anastomosis. A hole was then made on the posterior wall of the esophagus, between 2 cm and 3 cm above the ligature rope, and another hole was made at the anti-mesenteric border of the jejunum 40 cm distal to the Treitz ligament. A side-to-side esophagojejunal π-shaped anastomosis was performed through two holes. An entry hole was formed after the anastomosis. After checking the anastomosis, this entry hole was closed through an intestinal mesenteric hole pre-made on its opposite side. The resected esophagus and stomach, together with the afferent loop jejunum, were simultaneously

Using a 445-nm semiconductor laser for tissue incision, an effective cut is expected due to the special absorption properties of blue laser light in soft tissues. The aim of the present study was the histological evaluation of tissue samples after incision with a 445-nm diode laser. Forty soft tissue specimens were obtained from pork oral mucosa and mounted on a motorized linear translation stage. The handpiece of a high-frequency surgery device, a 970-nm semiconductor laser, and a 445-nm semiconductor laser were connected to the slide, allowing a constant linear movement (2 mm/s) and the same distance of the working tip to the soft tissue's surface. Four incisions were made each: (I) 970-nm laser with conditioned fiber tip, contact mode at 3-W cw; (II-III): 445-nm laser with non-conditioned fiber tip, contact mode at 2-W cw, and non-contact mode (1 mm) at 2 W; and (IV): high-frequency surgery device with straight working tip, 90° angulation, contact mode at 50 W. Histological analysis was performed after H&E staining of the embedded specimens at 35-fold magnification. The comparison of the incision depths showed a significant difference depending on the laser wavelength and the selected laser parameters. The highest incision depth was achieved with the 445-nm laser contact mode (median depth 0.61 mm, min 0.26, max 1.17, interquartile range 0.58) (p < 0.05) with the lowest amount of soft tissue denaturation (p < 0.05). The lowest incision depth was measured for the high-frequency surgical device (median depth 0.36 mm, min 0.12, max 1.12, interquartile range 0.23) (p < 0.05). Using a 445-nm semiconductor laser, a higher cutting efficiency can be expected when compared with a 970-nm diode laser and high-frequency surgery. Even the 445-nm laser application in non-contact mode shows clinically acceptable incision depths without signs of extensive soft tissue denaturation.

We compared changes in morphology and intraocular pressure (IOP) induced by clear 2.2-mm and 3.0-mm corneal incisions in a cohort of patients with cataracts. In 160 eyes (from 70 men and 90 women at the Ophthalmic Center of Sun Yat-sen University), optical coherence tomography and tonometry were performed at 1, 5, and 24 hours after cataract surgery. The main outcome measures were IOP, postoperative changes in Descemet membrane detachment (DMD), healing of the surgical incision, and inflammation of the anterior chamber. Five hours after surgery, patients with 2.2-mm and 3.0-mm incisions had lower IOPs (P < 0.017) as measured by noncontact tonometry, but the difference was significant only among patients with grade V cataracts (2.2 mm, 12.6 ± 1.2 mm Hg; 3.0 mm, 14.5 ± 0.9 mm Hg, P < 0.05). The incidence of endothelial gap at 24 hours after surgery was significantly higher in the 2.2-mm (50%) versus 3.0-mm (11.1%) group of patients with grade V cataracts (P < 0.05). The incidence of DMD at 5 hours was also significantly higher in the 2.2-mm group (75%) than in the 3.0-mm group (22.2%) only among patients with this grade (P < 0.05). Incision width made no difference among patients with grade I-IV lens nuclei; but among those with grade V, 3.0-mm incisions had significantly less endothelial gaping, less DMD, and higher mean IOPs. For these patients, smaller incisions may not be optimal, and eyes may be especially vulnerable within 5 hours of surgery.

Background: Concern regarding the quality of surgical training in obstetrics and gynecology residency programs is focusing attention on competency based education. Because open surgical skills cannot necessarily be translated into laparoscopic skills and with minimally invasive surgery becoming standard in operative gynecology, the discrepancy in training between obstetrics and gynecology will widen. Training on surgical simulators with virtual reality may improve surgical skills. However, before incorporation into training programs for gynecology residents the validity of such instruments needs to first be established. We sought to prove the construct validity of a virtual reality laparoscopic simulator, the SurgicalSimTM, by showing its ability to distinguish between surgeons with different laparoscopic experience. Methods: Eleven gynecologic surgeons (experts) and 11 perinatologists (controls) completed 3 tasks on the simulator, and 10 performance parameters were compared. Results: The experts performed faster, more efficiently, and with fewer errors, proving the construct validity of the SurgicalSim. Conclusions: Laparoscopic virtual reality simulators can measure relevant surgical skills and so distinguish between subjects having different skill levels. Hence, these simulators could be integrated into gynecology resident endoscopic training and utilized for objective assessment. Second, the skills required for competency in obstetrics cannot necessarily be utilized for better performance in laparoscopic gynecology. PMID:21985726

The article provides data on clinical diagnosis (4 patients, 4 eyes) and early surgical treatment of corneal intralamellar abscesses (ICA) in the zone of corneo-scleral tunnel incision after phacoemulsification (PE). ICA developed via corneo-scleral incision was a relatively reliable biomicroscopic sign of the beginning chronic endophthalmitis. Despite of massive nonsurgical treatment (antibiotics, glucocorticoids, non-steroid anti-inflammatory agents etc.) inflammation was not arrested completely, it recurred within 2,5-6 months after PE. Reconstructive conjunctivo-sclerokeratoplasty resulted in arrest of inflammation and visual function recovery in 3 patients. In one patient this procedure was not possible to perform because of total loss of visual functions due to chronic endophthalmitis.

Results of surgical treatment of 61 patients with injuries of the duodenum are analyzed. The causes of injuries were stab-incised wounds in 24 patients, missile wound -- in 7, closed abdominal trauma -- in 26, trauma of the duodenum during endoscopic papillosphincterotomy -- in 4. All the patients underwent surgery. Complications were seen in 32 (52.5%) patients, 21 patients died, lethality was 34.4%. Within the first 24 hours since the trauma 7 patients died due to severe combined trauma, blood loss, 54 patients survived acute period of trauma, including 28 patients after open trauma, 26 -- after closed and 4 -- after trauma of the duodenum during endoscopic papillosphincterotomy. Diagnostic and surgical policies are discussed. Results of treatment depending on kind and time of surgery are regarded. It is demonstrated that purulent complications due to retroperitoneal phlegmona, traumatic pancreatitis, pneumonia are the causes of significant number of unfavorable outcomes. Therefore, it is important to adequately incise and drainage infected parts of retroperitoneal fat tissue with two-lumen drainages. Decompression through duodenal tube is the effective procedure for prophylaxis of suture insufficiency and traumatic pancreatitis. Suppression of pancreatic and duodenal secretion with octreotid improves significantly surgical treatment results.

With the emphasis of current surgical practice being increasingly focused on reducing the invasiveness of procedures, new techniques and concepts are changing the approach to thoracic surgery. Robotics offers the benefits of scaled motion, tremor filtration, and remote telemanipulation. It may be theoretically possible to introduce the concept of telementoring into thoracic surgery. By coupling two consoles, it would be possible for a senior surgeon to guide a junior surgeon through an endoscopic procedure in which the clinicians were in different locations. The use of telepresence surgery would also enable surgeons to perform or assist in operations taking place in remote locations. Robotics has the potential to increase the applicability of endoscopic surgery to an increasing number of patients with technically complex thoracic problems. Given that this technology is in its infancy, it remains too early in the process to determine if robotics will be a significant "value-added" element of cardiothoracic surgery; however, the possibilities continue to be limited only by imagination and ingenuity.

Local antimicrobial administration for prophylaxis of surgical site infections.

PubMed

Huiras, Paul; Logan, Jill K; Papadopoulos, Stella; Whitney, Dana

2012-11-01

Despite a lack of consensus guidelines, local antibiotic administration for prophylaxis of surgical site infections is used during many surgical procedures. The rationale behind this practice is to provide high antibiotic concentrations at the site of surgery while minimizing systemic exposure and adverse effects. Local antibiotic administration for surgical site prophylaxis has inherent limitations in that antibiotics are applied after the incision is made, rather than the current standard for surgical site prophylaxis that recommends providing adequate antibiotic concentrations at the site before the incision. The efficacy and safety of local application of antibiotics for surgical site prophylaxis have been assessed in different types of surgery with a variety of antibiotic agents and methods of application. We identified 22 prospective, randomized, controlled trials that evaluated local application of antibiotics for surgical site prophylaxis. These trials were subsequently divided and analyzed based on the type of surgical procedure: dermatologic, orthopedic, abdominal, colorectal, and cardiothoracic. Methods of local application analyzed included irrigations, powders, ointments, pastes, beads, sponges, and fleeces. Overall, there is a significant lack of level I evidence supporting this practice for any of the surgical genres evaluated. In addition, the literature spans several decades, and changes in surgical procedures, systemic antibiotic prophylaxis, and microbial flora make conclusions difficult to determine. Based on available data, the efficacy of local antibiotic administration for the prophylaxis of surgical site infections remains uncertain, and recommendations supporting this practice for surgical site prophylaxis cannot be made. © 2012 Pharmacotherapy Publications, Inc.

After decades on the margins of primary health care, surgical and anaesthesia care is gaining increasing priority within the global development arena. The 2015 publications of the Disease Control Priorities third edition on Essential Surgery and the Lancet Commission on Global Surgery created a compelling evidenced-based argument for the fundamental role of surgery and anaesthesia within cost-effective health systems strengthening global strategy. The launch of the Global Alliance for Surgical, Obstetric, Trauma, and Anaesthesia Care in 2015 has further coordinated efforts to build priority for surgical care and anaesthesia. These combined efforts culminated in the approval of a World Health Assembly resolution recognizing the role of surgical care and anaesthesia as part of universal health coverage. Momentum gained from these milestones highlights the need to identify consensus goals, targets and indicators to guide policy implementation and track progress at the national level. Through an open consultative process that incorporated input from stakeholders from around the globe, a global target calling for safe surgical and anaesthesia care for 80% of the world by 2030 was proposed. In order to achieve this target, we also propose 15 consensus indicators that build on existing surgical systems metrics and expand the ability to prioritize surgical systems strengthening around the world.

Contemporary Obstetric Triage.

PubMed

Sandy, Edward Allen; Kaminski, Robert; Simhan, Hygriv; Beigi, Richard

2016-03-01

The role of obstetric triage in the care of pregnant women has expanded significantly. Factors driving this change include the Emergency Medical Treatment and Active Labor Act, improved methods of testing for fetal well-being, increasing litigation risk, and changes in resident duty hour guidelines. The contemporary obstetric triage facility must have processes in place to provide a medical screening examination that complies with regulatory statues while considering both the facility's maternal level of care and available resources. This review examines the history of the development of obstetric triage, current considerations in a contemporary obstetric triage paradigm, and future areas for consideration. An example of a contemporary obstetric triage program at an academic medical center is presented. A successful contemporary obstetric triage paradigm is one that addresses the questions of "sick or not sick" and "labor or no labor," for every obstetric patient that presents for care. Failure to do so risks poor patient outcome, poor patient satisfaction, adverse litigation outcome, regulatory scrutiny, and exclusion from federal payment programs. Understanding the role of contemporary obstetric triage in the current health care environment is important for both providers and health care leadership. This study is for obstetricians and gynecologists as well as family physicians. After completing this activity, the learner should be better able to understand the scope of a medical screening examination within the context of contemporary obstetric triage; understand how a facility's level of maternal care influences clinical decision making in a contemporary obstetric triage setting; and understand the considerations necessary for the systematic evaluation of the 2 basic contemporary obstetric questions, "sick or not sick?" and "labor or no labor?"

Since most liposuction incisions heal uneventfully, difficult healing in such incisions must be investigated. In the cases of two gynecomastia liposuction patients in which a water-based lubricating gel was used on the liposuction incisions, the incisions failed to heal. For both patients, workup uncovered palisading granulomas at the lateral inframammary fold incision sites several months after otherwise successful surgeries. These two cases are presented and the previous literature is reviewed, with consideration given to the etiology and prevention of such granulomas.

To evaluate first-intention healing of CO(2) laser, 4.0-MHz radiowave radiosurgery (RWRS), and scalpel incisions in ball pythons (Python regius). 6 healthy adult ball pythons. A skin biopsy sample was collected, and 2-cm skin incisions (4/modality) were made in each snake under anesthesia and closed with surgical staples on day 0. Incision sites were grossly evaluated and scored daily. One skin biopsy sample per incision type per snake was obtained on days 2, 7, 14, and 30. Necrotic and fibroplastic tissue was measured in histologic sections; samples were assessed and scored for total inflammation, histologic response (based on the measurement of necrotic and fibroplastic tissues and total inflammation score), and other variables. Frequency distributions of gross and histologic variables associated with wound healing were calculated. Gross wound scores were significantly greater (indicating greater separation of wound edges) for laser incisions than for RWRS and scalpel incisions at all evaluated time points. Necrosis was significantly greater in laser and RWRS incisions than in scalpel incision sites on days 2 and 14 and days 2 and 7, respectively; fibroplasia was significantly greater in laser than in scalpel incision sites on day 30. Histologic response scores were significantly lower for scalpel than for other incision modalities on days 2, 14, and 30. In snakes, skin incisions made with a scalpel generally had less necrotic tissue than did CO(2) laser and RWRS incisions. Comparison of the 3 modalities on the basis of histologic response scores indicated that use of a scalpel was preferable, followed by RWRS and then laser.

Obstetric fistula is a preventable and treatable condition predominately affecting women in low-income countries. Understanding the social context of obstetric fistula may lead to improved prevention and treatment. This study investigated social experiences of women with obstetric fistula seeking treatment at Mulago Hospital in Kampala, Uganda. A descriptive study was conducted among women seeking treatment for obstetric fistula during a surgical camp in July 2011 using a structured questionnaire. Descriptive statistics were computed regarding sociodemographics, obstetric history, and social experience. Fifty-three women participated; 39 (73.58%) leaked urine only. Median age was 29 years (range: 17-58), and most were married or separated. About half (28, 47.9%) experienced a change in their relationship since acquiring obstetric fistula. More than half (27, 50.94%) acquired obstetric fistula during their first delivery, despite almost everyone (50, 94.3%) receiving antenatal care. The median years suffering from obstetric fistula was 1.25. Nearly every participant's social participation changed in at least one setting (51, 96.23%). Most women thought that a baby being too big or having kicked their bladder was the cause of obstetric fistula. Other participants thought health care providers caused the fistula (15, 32.61%; n = 46), with 8 specifying that the bladder was cut during the operation (cesarean section). Knowing someone with obstetric fistula was influential in pursuing treatment. The majority of participants planned to return to family (40, 78.43%; n = 51) and get pregnant after repair (35, 66.04%; n = 53). Study participants experienced substantial changes in their social lives as a result of obstetric fistula, and there were a variety of beliefs regarding the cause. The complex social context is an important component to understanding how to prevent and treat obstetric fistula. Further elucidation of these factors may bolster current efforts in

To describe our technique of lenticule edge identification in small-incision lenticule extraction using the "meniscus sign" to prevent lenticule misdissection. Femtosecond laser application for small-incision lenticule extraction was performed. A "double ring" was visible, signifying the edge of the cap cut (outer ring) and lenticule cut (inner ring). The anterior and posterior lamellar planes were delineated in 2 different directions. During creation of the posterior lamellar channel, the lenticule edge was slightly pushed away from the surgeon to create a gap between the inner ring (diameter of the lenticule cut) and the lenticule edge. The lenticule edge assumed a frilled wavy appearance, and the meniscus sign was observed as a gap between the lenticule edge and the inner ring. The meniscus-shaped gap served as a landmark to identify the lenticule edge, and the relationship between the frilled lenticule edge and surgical instruments further acted as a guide to identify the correct plane of dissection. This technique was successfully undertaken in 50 eyes of 25 patients. The meniscus sign was observed in all cases, and no case had cap lenticular adhesions. The meniscus sign helps to identify the lenticule edge and correct dissection planes and provides a visual landmark during the entire surgical procedure.

Abstract Background: Laparoscopic and robot-assisted surgeries are performed under carbon dioxide insufflation. Switching from gas to an isotonic irrigant introduces several benefits and avoids some adverse effects of gas insufflation. We developed an irrigating device and apparatus designed for single-incision laparoscopic surgery and tested its advantages and drawbacks during surgery in a porcine model. Materials and Methods: Six pigs underwent surgical procedures under general anesthesia. A 30-cm extracorporeal cistern was placed over a 5–6-cm abdominal incision. The abdomen was irrigated with warm saline that was drained via a suction tube placed near the surgical field and continuously recirculated through a closed circuit equipped with a hemodialyzer as a filter. Irrigant samples from two pigs were cultured to check for bacterial and fungal contamination. Body weight was measured before and after surgery in four pigs that had not received treatments affecting hemodynamics or causing diuresis. Results: One-way flow of irrigant ensured laparoscopic vision by rinsing blood from the surgical field. Through a retroperitoneal approach, cystoprostatectomy was successfully performed in three pigs, nephrectomy in two, renal excision in two, and partial nephrectomy in one, under simultaneous ultrasonographic monitoring. Through a transperitoneal approach, liver excision and hemostasis with a bipolar sealing device were performed in three pigs, and bladder pedicle excision was performed in one pig. Bacterial and fungal contamination of the irrigant was observed on the draining side of the circuit, but the filter captured the contaminants. Body weight increased by a median of 2.1% (range, 1.2–4.4%) of initial weight after 3–5 hours of irrigation. Conclusions: Surgery under irrigation is feasible and practical when performed via a cistern through a small abdominal incision. This method is advantageous, especially in the enabling of continuous and free

Obstetric surgical site infections (SSIs) are common and expensive to the health care system but remain under reported given shorter postoperative hospital stays and suboptimal post-discharge surveillance systems. SSIs, for the purpose of this paper, are defined according to the Center for Disease Control and Prevention (1999) as infection incurring within 30 days of the operative procedure (in this case, Caesarean section [CS]). Demonstrate the feasibility of real-life use of a patient driven SSIs post-discharge surveillance system consisting of an online database and mobile phone technology (surgical mobile app - how2trak) among women undergoing CS in a Canadian urban centre. Estimate the rate of SSIs and associated predisposing factors. Prospective cohort of consecutive women delivering by CS at one urban Canadian hospital. Using surgical mobile app-how2trak-predetermined demographics, comorbidities, procedure characteristics, and self-reported symptoms and signs of infection were collected and linked to patients' incision self-portraits (photos) on postpartum days 3, 7, 10, and 30. A total of 105 patients were enrolled over a 5-month period. Mean age was 31 years, 13% were diabetic, and most were at low risk of surgical complications. Forty-six percent of surgeries were emergency CSs, and 104/105 received antibiotic prophylaxis. Forty-five percent of patients (47/105) submitted at least one photo, and among those, one surgical site infection was detected by photo appearance and self-reported symptoms by postpartum day 10. The majority of patients whom uploaded photos did so multiple times and 43% of them submitted photos up to day 30. Patients with either a diagnosis of diabetes or self-reported Asian ethnicity were less likely to submit photos. Post-discharge surveillance for CS-related SSIs using surgical mobile app how2trak is feasible and deserves further study in the post-discharge setting. Copyright © 2017. Published by Elsevier Inc.

To search for a simple and effective surgical approach to the management of moderate to severe pediatric concealed penis in children. We used Devine's technique via incision between the penis and scrotum in the treatment of 68 cases of moderate to severe pediatric concealed penis. The patients were aged 3 -13 (mean 6.5) years, 30 with moderate and 38 with severe pediatric concealed penis. This strategy achieved good near- and long-term effects and satisfactory appearance of the penis, which was similar to that of circumcision. At 3 months after surgery, the penile length was 3 - 5.2 cm, averaging (2.35 +/- 0.35) cm. Devine's technique via incision between the penis and scrotum is a simple and effective surgical option for moderate to severe pediatric concealed penis in children.

Trends in the Surgical Correction of Gynecomastia.

Brown, Rodger H; Chang, Daniel K; Siy, Richard; Friedman, Jeffrey

Gynecomastia refers to the enlargement of the male breast due to a proliferation of ductal, stromal, and/or fatty tissue. Although it is a common condition affecting up to 65% of men, not all cases require surgical intervention. Contemporary surgical techniques in the treatment of gynecomastia have become increasingly less invasive with the advent of liposuction and its variants, including power-assisted and ultrasound-assisted liposuction. These techniques, however, have been largely limited in their inability to address significant skin excess and ptosis. For mild to moderate gynecomastia, newer techniques using arthroscopic morcellation and endoscopic techniques promise to address the fibrous component, while minimizing scar burden by utilizing liposuction incisions. Nevertheless, direct excision through periareolar incisions remains a mainstay in treatment algorithms for its simplicity and avoidance of additional instrumentation. This is particularly true for more severe cases of gynecomastia requiring skin resection. In the most severe cases with significant skin redundancy and ptosis, breast amputation with free nipple grafting remains an effective option. Surgical treatment should be individualized to each patient, combining techniques to provide adequate resection and optimize aesthetic results.

To determine the frequency and distribution of Adverse Events (AE) in obstetrics departments at Spanish hospitals. We present a retrospective cohort study including 816 women admitted to the obstetrics departments at 41 hospitals that took part in the National Adverse Effects Study in Spain (ENEAS) and an extension of this study in all hospitals located in two Autonomous Regions. To identify AE, nurses from each participating hospital examined all medical records, and completed a validated screening guide. A team of external reviewers evaluated the medical records of all women who met at least one of the criteria in the screening guide to verify all AE. The main outcome measure was the incidence of AE during hospitalization. The cumulative incidence of patients with obstetric care-related AE was 3.6% (95% CI 2.3-4.8). The most frequent AE were those related with surgical interventions or procedures (59.4%). None of the AE detected were considered severe. 36.7% of the AE lengthened the woman's hospital stay, and 13.3% led to hospital admission. Additional procedures were needed after 71.9% of the AE, and additional treatment was needed after 59.4%. 56.3% of the AE were considered preventable. Obstetric care is characterized by generally younger ages among patients, their low frequency of comorbidities and high expectations for successful outcomes of care. However, some factors can increase obstetric risk and favor the appearance of preventable incidents and AE. Systems are needed to detect preventable AE, and measures are needed to reduce risks or attenuate their consequences.

To share surgical management experiences of intra-abdominal intrauterine devices (IUDs) in tertiary center. A total of 27 patients were retrospectively analyzed. This retrospective study was conducted between September 1992 and April 2013 at Department of Obstetrics and Gynecology Tepecik Research and Training Hospital, Izmir, Turkey. Demographic findings, diagnostic methods, and operative notes of patients were obtained from the patient file. Of the 27 IUDs, nine (33.3%) were in omentum, four (15%) were in Douglas pouch, one in left sacrouterine ligament, one in uterovesical space and one in fundus posterior, six (22%) in left adnexial region, one in abdominal wall, one was subdiaphragmatic, one in ligamentum latum, and one in jejunum. Almost all of the patients had TCu-380 A IUDs. Seventeen patients (63%) were managed by laparoscopy, whereas laparotomy was required in ten (37%). Adhesions were found in 23 of 27 (85%) patients with varying degrees. In four cases the incision was extended due to adhesions. A missing string was the first finding of an intra-abdominal IUD. Pelvic ultrasonography, X-ray, and hysteroscopy methods should be performed in order to detect the localization of IUD in case of a missing string. Surgical approach should be the first treatment option for intra-abdominal IUDs.

Uterine rupture is an obstetric calamity with surgery as its management mainstay. Uterine repair without tubal ligation leaves a uterus that is more prone to repeat rupture while uterine repair with bilateral tubal ligation (BTL) or (sub)total hysterectomy predispose survivors to psychosocial problems like marital disharmony. This study aims to evaluate obstetricians' perspectives on surgical decision making in managing uterine rupture. A questionnaire-based cross-sectional study of obstetricians at the 46th annual scientific conference of Society of Gynaecology and Obstetrics of Nigeria in 2012. Data was analysed by descriptive and inferential statistics. Seventy-nine out of 110 obstetricians (71.8%) responded to the survey, of which 42 (53.2%) were consultants, 60 (75.9%) practised in government hospitals and 67 (84.8%) in urban hospitals, and all respondents managed women with uterine rupture. Previous cesarean scars and injudicious use of oxytocic are the commonest predisposing causes, and uterine rupture carries very high incidences of maternal and perinatal mortality and morbidity. Uterine repair only was commonly performed by 38 (48.1%) and uterine repair with BTL or (sub) total hysterectomy by 41 (51.9%) respondents. Surgical management is guided mainly by patients' conditions and obstetricians' surgical skills. Obstetricians' distribution in Nigeria leaves rural settings starved of specialist for obstetric emergencies. Caesarean scars are now a rising cause of ruptures. The surgical management of uterine rupture and obstetricians' surgical preferences vary and are case scenario-dependent. Equitable redistribution of obstetricians and deployment of medical doctors to secondary hospitals in rural settings will make obstetric care more readily available and may reduce the prevalence and improve the outcome of uterine rupture. Obstetrician's surgical decision-making should be guided by the prevailing case scenario and the ultimate aim should be to avert

The incidence of fascial dehiscence and incisional hernia after two methods for abdominal wound closure (rectus sheath relaxation incisions and conventional mass closure) was studied in a randomized prospective clinical trial in a consecutive series of 100 patients undergoing midline laparotomy for peritonitis. The two groups were well matched for etiologies of peritonitis, the surgical procedures performed, and the presence of known risk factors for fascial dehiscence. Fifty patients each were randomized either to the conventional continuous mass closure procedure or the rectus sheath relaxation incision technique (designed to increase wound elasticity and decrease tension in the suture line) using identical polypropylene sutures. The incidence of postoperative complications such as duration of ileus, chest infection, and wound infection were not statistically different between the two groups. The intensity of postoperative pain in the rectus sheath relaxation incision group was significantly less. The incidence of wound hematoma was significantly increased in the rectus sheath relaxation incision group. The incidences of fascial dehiscence (16% vs,28%; p < 0.05) and incisional hernia (18% vs, 30%; p < 0.05) were significantly lower after rectus sheath relaxation incisions compared to conventional mass closure. Closure of the midline laparotomy wound in cases of peritonitis using the rectus sheath relaxation technique is safe and less painful, provides increased wound elasticity and decreased tension on the suture line, and significantly decreases the incidence of wound dehiscence.

Recent enthusiasm in the surgical community for less invasive surgical approaches has resulted in widespread application of single-incision techniques. This has been most commonly applied in laparoscopic cholecystectomy in general surgery. Cosmesis appears to be improved, but other advantages remain to be seen. Feasibility has been demonstrated, but there is little description in the current literature regarding complications. We report the case of a patient who previously underwent single-incision laparoscopic cholecystectomy for symptomatic gallstone disease. After a brief symptom-free interval, she developed acute pancreatitis. At evaluation, imaging results of ultrasonography and magnetic resonance cholangiopancreatography demonstrated a retained gallbladder with cholelithiasis. The patient was subsequently referred to our hospital, where she underwent further evaluation and surgical intervention. Our patient underwent 4-port laparoscopic remnant cholecystectomy with transcystic common bile duct exploration. Operative exploration demonstrated a large remnant gallbladder and a partially obstructed cystic duct with many stones. Transcystic exploration with balloon extraction resulted in duct clearance. The procedure took 75 minutes, with minimal blood loss. The patient's postoperative course was uneventful. Final pathology results demonstrated a remnant gallbladder with cholelithiasis and cholecystitis. This report is the first in the literature to describe successful laparoscopic remnant cholecystectomy and transcystic common bile duct exploration after previous single-port cholecystectomy. Although inadvertent partial cholecystectomy is not unique to this technique, single-port laparoscopic procedures may result in different and significant complications.

Modified incision for maxillectomy: our experience.

Radical maxillectomy has usually been done by the classical Weber Ferguson incision since age old times and still is being used widely due to its advantage of excellent exposure and minimal scarring as the incision follows the natural skin crease. In our modification of radical maxillectomy incision we avoid a scar on the midface by performing a midface degloving and combining it with a subconjunctival eye incision thus avoiding any cosmetic deformity and associated eye complication. It also avoids the late complication of cutaneous fistula following radiotherapy to these areas and due to early healing of the wound, early radiotherapy can be started.

Objective The goal of this study was to evaluate the first formal counseling program for obstetric fistula patients in Eritrea. Methods To evaluate the impact of the counseling program, clients were interviewed both before pre-operative counseling and again after post-operative counseling. A questionnaire was used in the interviews to assess women's knowledge about fistula, self-esteem, and their behavioral intentions for health maintenance and social reintegration following surgical repair. In addition, two focus groups were conducted with a total of 19 clients assessing their experiences with the surgical care and counseling. Results Data from the questionnaires revealed significant improvements in women's knowledge about fistula, self-esteem, and behavioral intentions following counseling. Focus group data also supported increased knowledge and self-esteem. Conclusion Evaluation of the short-term impact of an initial formal counseling program for fistula patients in sub-Saharan Africa affirmed the positive effects that such a program has for fistula patients, with increased knowledge about the causes of fistula, fistula prevention and enhanced self-esteem. Practical implications Culturally appropriate counseling can be incorporated into services for surgical repair of obstetric fistula in low-resource settings and has the potential to improve the physical and mental well-being of women undergoing fistula repair.

To compare morphologic differences between freehand diamond or femtosecond laser-assisted penetrating and intrastromal arcuate incisions. Freehand diamond blade, corneal arcuate incisions (180° apart, 60° arc lengths) and 150 kHz femtosecond laser (80% scheimpflug pachymetry depth corneal thickness) arcuate incisions were performed in rabbits. Intrastromal arcuate incisions (100 μm above Descemet's membrane, 100 μm below epithelium) were performed in rabbit corneas (energy 1.2 μJ, spot line separation 3 × 3 μm, 90° side cut angle). Eyes were examined by slit lamp and light microscopy up to 47 days post-procedure. Freehand diamond blade penetrating incisions, and femtosecond laser penetrating and intrastromal arcuate incisions (energy 1.8 μJ, spot line separation 2 × 2 μm) were performed in cadaver eyes. Optical coherence tomography was performed immediately after surgery and the corneas were fixed for light scanning and transmission electron microscopy. The rabbit model showed anterior stromal inflammation with epithelial hyperplasia in penetrating blade and laser penetrating wounds. The laser intrastromal and penetrating incisions showed localized constriction of the stromal layers of the cornea near the wound. In cadaver eyes, penetrating wound morphology was similar between blade and laser whereas intrastromal wounds did not affect the cornea above or below incisions. Penetrating femtosecond laser arcuate incisions have more predictable and controlled outcomes shown by less post-operative scarring than incisions performed with a diamond blade. Intrastromal incisions do not affect uncut corneal layers as demonstrated by histopathology. The femtosecond laser has significant advantages in its ability to make intrastromal incisions which are not achievable by traditional freehand or mechanical diamond blades.

Treatment of Mandibular Condyle Fractures Using a Modified Transparotid Approach via the Parotid Mini-Incision: Experience with 31 Cases

2013-01-01

Surgery for mandibular condyle fractures must allow direct vision of the fracture, reduce surgical trauma and achieve reduction and fixation while avoiding facial nerve injury. This prospective study was conducted to introduce a new surgical approach for open reduction and internal fixation of mandibular condyle fractures using a modified transparotid approach via the parotid mini-incision, and surgical outcomes were evaluated. The modified transparotid approach via the parotid mini-incision was applied and rigid internal fixation using a small titanium plate was carried out for 36 mandibular condyle fractures in 31 cases. Postoperative follow-up of patients ranged from 3 to 26 months; in the first 3 months after surgery, outcomes for all patients were analyzed by evaluating the degree of mouth opening, occlusal relationship, facial nerve function and results of imaging studies. The occlusal relationships were excellent in all patients and none had symptoms of intraoperative ipsilateral facial nerve injury. The mean degree of mouth opening was 4.0 (maximum 4.8 cm, minimum 3.0 cm). No mandibular deviations were noted in any patient during mouth opening. CT showed complete anatomical reduction of the mandibular condyle fracture in all patients. The modified transparotid approach via the smaller, easily concealed parotid mini-incision is minimally invasive and achieves anatomical reduction and rigid internal fixation with a simplified procedure that directly exposes the fracture site. Study results showed that this procedure is safe and feasible for treating mandibular condyle fracture, and offers a short operative path, protection of the facial nerve and satisfactory aesthetic outcomes.

To study the social integration of women supported in the urology department of the University Hospital of Point G for obstetric urogenital fistula. Prospective study conducted over a period of 13 months from June 2008 to June 2009 in the Department of Urology at the University Hospital of Point G. The study included all patients who have been operated on at least twice for obstetric fistula genitourinary. Records of surgical, medical records and tracking sheets for each patient were the media database. Situation before treatment: before surgical treatment, 76.92% of patients were rejected by their spouses. The family attended the patient in 84.62% of cases. Situation after treatment: after treatment, 90.31% of women with fistula lived in the matrimonial home or family. The resumption of business activity was announced by 11.2% of patients. Among the women, 93.7% participated in housework. The number of patient intervention ranged from two to five. Healing (fistula closed and no sphincter dysfunction) was complete in 50% of cases. Among the women, 11.54% had sphincter dysfunction after closure of the fistula, which makes a total of fistula closed more than 61% after at least two attempts. The urogenital fistulas are not a fatal disease but is a real handicap for women who suffer to conduct a socio-cultural and economic mainstream. Generally excluded from the ongoing operations of the company, these women are more integrated after successful surgical treatment of the fistula. Copyright © 2013 Elsevier Masson SAS.

Objective: Pfanennstiel incision is the most commonly used incision for cesarean section, but may not be the best. This study compared the modified Joel-Cohen incision with the Pfannenstiel incision to evaluate whether techniques to open the abdomen might influence operative time, and maternal and neonatal outcomes. Material and Methods: In a randomized comparative trial, 302 women with gestational age >34 weeks, requiring cesarean section, were randomly assigned to either modified Joel-Cohen incision or Pfannenstiel incision for entry into the peritoneal cavity. The primary outcome measure was total time required for performing operation and secondary outcome measures were baby extraction time, number of haemostatic procedures used in the abdominal wall, postoperative morbidity, postoperative hospital stay and neonatal outcome. Results: Mean total operative time was significantly less in the modified Joel-Cohen group as compared to the Pfannenstiel group (29.81 vs 32.67 min, p<0.0001, 95%CI=2.253 to 3.467). Time taken to deliver the baby and haemostatic procedures required during operation were also significantly less in the modified Joel-Cohen group as compared to the Pfannenstiel group. Requirement of strong analgesics was higher in the Pfannenstiel group (53.64% vs 21.85%, p<0.0001). There was no statically significant difference in the incidence of postoperative wound complications but postoperative stay in hospital was significantly less in the modified Joel-Cohen group (p=0.002). Neonatal outcomes were similar in both groups. Conclusion: The modified Joel-Cohen incision for entry into peritoneal cavity during cesarean section is associated with reduced mean total operative and baby extraction times with less postoperative pain and shorter hospital stay, which may be beneficial and cost effective.

We sought to determine the extent to which recent increases in levels of gender and racial diversity in the overall resident-physician workforce were evident among core-surgical specialty resident workforces. Chi-square tests for trend assessed the importance of changes from 1996 to 2004 in proportions of women and African Americans in the surgery-resident workforce. Surgery-resident trends were compared with overall resident workforce trends using two-tailed t-tests to compare regression slopes that quantified rates of change over time. Chi-square tests assessed differences between proportions of women and African Americans in the current overall board-certified workforce and their proportions in the surgery board-certified workforce. From 1996 to 2004, proportions of women increased in all seven surgical specialties studied. Compared with the overall trend toward increasing proportions of women in the resident workforce, the trend in one surgical specialty was larger (obstetrics/gynecology, p < 0.01), four were similar (each p > 0.05), and two were smaller (each p < 0.001). Proportions of African Americans increased in four specialties. Compared with the overall trend, trends in two specialties were larger (obstetrics/gynecology and neurologic surgery, each p < 0.01) and two were similar (each p > 0.05). Proportions of African Americans decreased in three specialties (each p < 0.01). Proportions of women and African Americans in every board-certified specialty workforce, except obstetrics/gynecology, remained lower than in the overall board-certified workforce (each p < 0.01). Many demographic disparities between the surgery-resident and overall-resident workforces have persisted since 1996 and will likely perpetuate ongoing surgery board-certified workforce disparities.

Obstetric antiphospholipid syndrome.

2016-04-01

Obstetric antiphospholipid syndrome is an acquired autoimmune disorder that is associated with various obstetric complications and, in the absence of prior history of thrombosis, with the presence of antiphospholipid antibodies directed against other phospholipids, proteins called cofactors or PL-cofactor complexes. Although the obstetric complications have been related to the procoagulant properties of antiphospholipid antibodies, pathological studies of human placenta have shown the proinflammatory capacity of antiphospholipid antibodies via the complement system and proinflammatory cytokines. There is no general agreement on which antiphospholipid antibodies profile (laboratory) confers the greatest obstetric risk, but the best candidates are categories I and IIa. Combined treatment with low doses of aspirin and heparin achieves good obstetric and maternal outcomes. In this study, we also review the therapeutic possibilities in refractory cases, although the likelihood of progressing to other autoimmune diseases is low. We briefly comment on incomplete obstetric antiphospholipid syndrome, also known as antiphospholipid antibody-mediated pregnancy morbidity syndrome.

In this study, conducted by Pacific Northwest National Laboratory for the U.S. Army Corps of Engineers, Portland District, we measured differences in survival and growth, incision openness, transmitter loss, wound healing, and erythema among abdominal incisions on the linea alba, lateral and parallel to the linea alba (muscle-cutting), and following the underlying muscle fibers (muscle-sparing). A total of 936 juvenile Chinook salmon were implanted with both Juvenile Salmon Acoustic Tracking System transmitters (0.43 g dry) and passive integrated transponder tags. Fish were held at 12°C (n = 468) or 20°C (n = 468) and examined once weekly over 98 days.more » We found survival and growth did not differ among incision groups or between temperature treatment groups. Incisions on the linea alba had less openness than muscle-cutting and muscle-sparing incisions during the first 14 days when fish were held at 12°C or 20°C. Transmitter loss was not different among incision locations by day 28 when fish were held at 12°C or 20°C. However, incisions on the linea alba had greater transmitter loss than muscle-cutting and muscle-sparing incisions by day 98 at 12°C. Results for wound closure and erythema differed among temperature groups.

The benefits of minimally invasive surgery in pediatric urology, such as reduced length of hospital stay and postoperative pain, are less predictable compared to findings in the adult literature. We evaluated the choices that adult patients make for themselves and their children regarding scar location. We surveyed the preference for scar location/size based on surgery for bladder and kidney procedures with additional questions assessing the impact of a hidden incision, length of hospital stay and pain. The survey was posted to Amazon® Mechanical Turk®. We analyzed a total of 954 completed surveys. Surgical history was reported in 660 surveys (69%) with scar bother reported in 357 (54.2%). For pelvic surgery the initial choice was a Pfannenstiel incision for 434 respondents (45.5%), laparoscopy port incisions for 392 (41.1%) and no preference for incision location for 126 (13.2%). When incisions were illustrated relative to undergarments, 718 respondents (75.3%) chose Pfannenstiel. For kidney surgery 567 respondents (59.4%) initially chose the dorsal lumbotomy incision, 170 (17.8%) chose a flank incision, 105 (11.0%) chose laparoscopy ports and 110 (11.5%) had no preference. Respondents were told that minimally invasive surgery might result in less pain/length of hospital stay and were asked to restate the incision choice. For pelvic surgery 232 of 434 respondents (53.5%) who had chosen Pfannenstiel and 282 of 394 (71.6%) who had chosen laparoscopy remained consistent (p <0.001). For kidney surgery 96 respondents (56.5%) who chose a flank incision, 322 (56.8%) who chose dorsal lumbotomy and 68 (64.2%) who chose laparoscopy remained consistent (p = 0.349). Agreement between the incision choice by respondent as a child and for a child was 82% (κ = 0.69) for pelvic surgery and 84.6% (κ = 0.75) for kidney surgery. The smallest incision is not always the patient preferred incision, particularly in childhood when pain, length of hospital stay and blood loss may be

Trends in the Surgical Correction of Gynecomastia

2015-01-01

Gynecomastia refers to the enlargement of the male breast due to a proliferation of ductal, stromal, and/or fatty tissue. Although it is a common condition affecting up to 65% of men, not all cases require surgical intervention. Contemporary surgical techniques in the treatment of gynecomastia have become increasingly less invasive with the advent of liposuction and its variants, including power-assisted and ultrasound-assisted liposuction. These techniques, however, have been largely limited in their inability to address significant skin excess and ptosis. For mild to moderate gynecomastia, newer techniques using arthroscopic morcellation and endoscopic techniques promise to address the fibrous component, while minimizing scar burden by utilizing liposuction incisions. Nevertheless, direct excision through periareolar incisions remains a mainstay in treatment algorithms for its simplicity and avoidance of additional instrumentation. This is particularly true for more severe cases of gynecomastia requiring skin resection. In the most severe cases with significant skin redundancy and ptosis, breast amputation with free nipple grafting remains an effective option. Surgical treatment should be individualized to each patient, combining techniques to provide adequate resection and optimize aesthetic results. PMID:26528088

Novel uses of surgical robotics in head and neck surgery.

To demonstrate the utility of robotically assisted approaches in head and neck surgery. Two teenage patients, one with a solitary thyroid nodule who was scheduled for a right thyroid lobectomy and the other with intractable seizures who was scheduled for placement of a vagal nerve stimulator were offered the option of a robotically assisted technique using a transaxillary endoscopic approach. Both procedures were completed successfully using the da Vinci surgical system (Intuitive Surgical, Sunnyvale, California). A 12 mm telescope and 5 mm instruments were used. There was sufficient mobility of the robotic arms despite the small working space. There were no complications, minimal pain in the axillary incisions, and patient satisfaction was high. Operative times were 4.5 and 4.2 hours, respectively. Transaxillary, endoscopic, robotically assisted approaches to the head and neck are feasible. The addition of robotics improves surgical dexterity in a difficult-to-reach anatomic region. Patient satisfaction appears high because of the avoidance of a cervical incision.

New therapeutics to manage post-surgical pain are needed to mitigate the liabilities of opioid and other analgesics. Our previous work shows that key modulators of excitability in peripheral nociceptors, such as extracellular signal-regulated kinases (ERK) are inhibited by activation of adenosine monophosphate activated protein kinase (AMPK). We hypothesized that AMPK activation would attenuate acute incision-evoked mechanical hypersensitivity and the development of hyperalgesic priming caused by surgery in mice. Here we have used a variety of administration routes and combinations of AMPK activators to test this hypothesis. Topical administration of a resveratrol-based cream inhibited acute mechanical hypersensitivity evoked by incision and blocked the development of hyperalgesic priming. We also observed that systemic administration of metformin dose-dependently inhibited incision-evoked mechanical hypersensitivity and hyperalgesic priming. Interestingly, low doses of systemic metformin and local resveratrol that had no acute effect were able to mitigate development of hyperalgesic priming. Combined treatment with doses of systemic metformin and local resveratrol that were not effective on their own enhanced the acute efficacy of the individual AMPK activators for post-surgical mechanical pain alleviation and blocked the development of hyperalgesic priming. Finally, we used dorsal root ganglion (DRG) neurons in culture to show that resveratrol and metformin given in combination shift the concentration-response curve for AMPK activation to the left and increase the magnitude of AMPK activation. Therefore, we find that topical administration is an effective treatment route of administration and combining systemic and local treatments led to anti-nociceptive efficacy in acute mechanical hypersensitivity at doses that were not effective alone. Collectively our work demonstrates a specific effect of AMPK activators on post-surgical pain and points to novel therapeutic

The reluctance to incise skin with electrocautery is partly attributable to concerns about excessive scarring and poor wound healing. However, recently no difference was reported in wound complications between the cold scalpel and electrocautery scalpel. We assessed the safety and efficacy of electrocautery skin incision in 22 scalp incisions, including 4 cases of reoperation. Electrocautery skin incisions were created using a sharp needle electrode. The generator unit was set on cutting mode, with power of 6 W and 330 kHz sinusoid waveform. Subcutaneous dissections also used the sharp needle electrode, set on coagulating mode, with power of 10 W and 1 MHz pulse-modulated waveform. Galea incisions used a standard blade tip, set on coagulating mode, with power of 20 W and 1 MHz pulse-modulated waveform. Skin incision with the sharp needle electrode caused no charring of the wound. Little bleeding or oozing were observed and skin clips were not necessary. No wound complication such as necrosis or infection occurred. Electrocautery skin incisions for re-operations were also performed safely without complications. Electrocautery skin incision is sufficiently safe procedure not only for first operation but also for re-operation. Electrocautery skin incision is efficacious, especially for extended operation times, because of little blood loss from the edges of skin incision and possible avoidance of skin edge necrosis or alopecia caused by skin clips.

Obstetric fistula is a debilitating birth injury that affects an estimated 2-3 million women globally, most in sub-Saharan Africa and Asia. The urinary and/or fecal incontinence associated with fistula affects women physically, psychologically and socioeconomically. Surgical management of fistula is available with clinical success rates ranging from 65-95 %. Previous research on fistula repair outcomes has focused primarily on clinical outcomes without considering the broader goal of successful reintegration into family and community. The objectives for this study are to understand the process of family and community reintegration post fistula surgery and develop a measurement tool to assess long-term success of post-surgical family and community reintegration. This study is an exploratory sequential mixed-methods design including a preliminary qualitative component comprising in-depth interviews and focus group discussions to explore reintegration to family and community after fistula surgery. These results will be used to develop a reintegration tool, and the tool will be validated within a small longitudinal cohort (n = 60) that will follow women for 12 months after obstetric fistula surgery. Medical record abstraction will be conducted for patients managed within the fistula unit. Ethical approval for the study has been granted. This study will provide information regarding the success of family and community reintegration among women returning home after obstetric fistula surgery. The clinical and research community can utilize the standardized measurement tool in future studies of this patient population.

To explore the clinical application of mastectomy with single incision followed by immediate laparoscopic-assisted breast reconstruction with latissimus dorsi muscle flap. Fifteen women with primary early breast cancer, 3 women with breast ductal carcinoma in situ, and 7 women with severe plasma cell mastitis were treated with partial mastectomy or total mastectomy, sentinel lymph node biopsy, or axillary lymph node dissection through a breast lateral transverse incision. Subsequent breast reconstruction with latissimus dorsi muscle flap was assisted by laparoscopy. The patient's position, time used in dissecting latissimus dorsi muscle flap, size of latissimus dorsi muscle flap, postoperative complications, and the cosmetic results after reconstruction were assessed. All the operations were well done through the breast lateral transverse incision and assistance of laparoscopy. The patient's position was changed only once during the operation. It took 1.5 to 2 hours to dissect latissimus dorsi muscle flap. The sizes of the latissimus dorsi muscle flap were 5 to 8 × 12 to 16 cm. There were no serious postoperative complications noted. The patients were satisfied with the appearance of the breasts and the small surgical scar. The surgical approach introduced is minimally invasive with concealed scar and outstanding cosmetic results. It is worth promoting in clinical application.

Single-incision laparoscopic surgery (SILS) aims to eliminate multiple port incisions. Although general operative principles of SILS are similar to conventional laparoscopic surgery, operative techniques are not standardized. This review aims to evaluate the current use of SILS published in the literature by examining the types of operations performed, techniques employed, and relevant complications and morbidity. This review considered a total of 94 studies reporting 1889 patients evaluating 17 different general surgical operations. There were 8 different access techniques reported using conventional laparoscopic instruments and specifically designed SILS ports. There is extensive heterogeneity associated with operating methods and in particular ways of overcoming problems with retraction and instrumentation. Published complications, morbidity, and hospital length of stay are comparable to conventional laparoscopy. Although SILS provides excellent cosmetic results and morbidity seems similar to conventional laparoscopy, larger randomized controlled trials are needed to assess the safety and efficacy of this novel technique.

This study was aimed to detect the positions of mental canal and incisive nerve canal as well as the prolongation of mandibular canal in interforaminal region in Chinese population to supply the reference data of the surgical safe zone in chin for clinicians. A total of 80 formalin-fixed semi-mandibles of Chinese adult cadavers were dissected, the positions and courses of mental canal and incisive nerve canal as well as the prolongation of mandibular canal in interforaminal region were measured. The mental foramina were present in all cases (100 %), and most of them were located below 2nd premolar (58.75 %). Accessory mental foramina were observed in 5 %. The anterior end of mandibular canal, extending along the course of 7.37 ± 1.10 mm above the lower border of mandible to interforaminal region about 3.54 ± 0.70 mm medial to the mental foramen, most often ended below between the two premolars (73.75 %), where it continued as the incisive nerve canal (100 %) and the mental canal (96.25 %). Mental canal, with the wall formed by compact bone, being 2.60 ± 0.60 mm in diameter and 4.01 ± 1.20 mm in length, opened into mental foramen. Incisive nerve canal, with the wall formed by thin compact bone and/or partly or completely by spongy bone, being 1.76 ± 0.27 mm in diameter and 24.87 ± 2.23 mm in length, extended to the incisor region along the course of 9.53 ± 1.43 mm above the lower border of mandible, and most often ended below the lateral incisor (70.00 %). This research recommended for chin operations in Chinese population: the surgical safe zone could be set in the region about over 4 mm anterior to the mental foramen, and over 12 mm above inferior border of mandible for anterior alveolar surgery, or within 9 mm above inferior border of mandible for genioplasty.

With the resection of pituitary lesions, the anterior pituitary gland often obstructs transsphenoidal access to the lesion. In such cases, a gland incision and/or partial gland resection may be required to obtain adequate exposure. We investigate this technique and determine the associated risk of post-operative hypopituitarism. All patients who underwent surgical resection of a pituitary adenoma or Rathke cleft cyst (RCC) between July 2007 and January 2013 were analyzed for pre- and post-operative hormone function. The cohort of patients with gland incision/resection were compared to a case-matched control cohort of pituitary surgery patients. Total hypophysectomy patients were excluded from outcome analysis. Of 372 operations over this period, an anterior pituitary gland incision or partial gland resection was performed in 79 cases (21.2 %). These include 53 gland incisions, 12 partial hemi-hypophysectomies and 14 resections of thinned/attenuated anterior gland. Diagnoses included 64 adenomas and 15 RCCs. New permanent hypopituitarism occurred in three patients (3.8 %), including permanent DI (3) and growth hormone deficiency (1). There was no significant difference in the rate of worsening gland dysfunction nor gain of function. Compared to a control cohort, there was a significantly lower incidence of transient DI (1.25 vs. 11.1 %, p = 0.009) but no significant difference in permanent DI (3.8 vs. 4.0 %) in the gland incision group. Selective gland incisions and gland resections were performed in over 20 % of our cases. This technique appears to minimize traction on compressed normal pituitary gland during removal of large lesions and facilitates better visualization and removal of cysts, microadenomas and macroadenomas.

To compare the efficacy of correcting myopic astigmatism with femtosecond laser small-incision lenticule extraction (SMILE, Carl Zeiss Meditec AG) versus laser-assisted subepithelial keratectomy (LASEK). The study was conducted at the Ophthalmology Department, Eye and ENT Hospital, Shanghai, China. A retrospective, cross-sectional study. This study included patients who underwent small-incision lenticule extraction or LASEK for the correction of myopia and myopic astigmatism. Preoperative and 6-month postoperative astigmatism values were analyzed. The efficacies of the 2 surgeries to correct astigmatism were compared. A total of 180 right eyes of 180 patients (small-incision lenticule extraction: n = 113, LASEK: n = 67) were included. No significant difference was found between the 2 groups in the preoperative astigmatism (small-incision lenticule extraction: 1.16 ± 0.85D, LASEK: 1.16 ± 0.83D, P > .05) or the postoperative astigmatism (small-incision lenticule extraction: 0.35 ± 0.37D; LASEK: 0.31 ± 0.42D, P > .05), determined by manifest refraction. No significant difference was found between the 2 groups in surgically induced astigmatism vector (small-incision lenticule extraction: 1.13 ± 0.83D, LASEK: 1.01 ± 0.65D, P > .05). The correction index was higher for the small-incision lenticule extraction group (1.05 ± 0.53) than for the LASEK group (0.95 ± 0.21, P = .045). The postoperative astigmatism was significantly higher for the small-incision lenticule extraction group when the preoperative astigmatism was 1.0 D or less (small-incision lenticule extraction: 0.26 ± 0.30D, LASEK: 0.12 ± 0.20D, P = .007) and lower for the small-incision lenticule extraction group when the preoperative astigmatism was more than 2.0 D (small-incision lenticule extraction: 0.48 ± 0.37D, LASEK: 0.89 ± 0.46D, P = .002). An adjustment of nomograms for correcting low astigmatism (≤1.0 D) by small-incision lenticule extraction is suggested due to the tendency toward

OBJECTIVE To describe the technique, clinical findings, and short-term outcome in dogs undergoing laparoscopic-assisted incisional gastropexy with a reusable single-incision surgery port. DESIGN Retrospective case series. ANIMALS 14 client-owned dogs. PROCEDURES Medical records of dogs referred for elective laparoscopic gastropexy between June 2012 and August 2013 were reviewed. History, signalment, results of physical examination and preoperative laboratory testing, surgical procedure, duration of surgery, postoperative complications, duration of hospital stay, and short-term outcome were recorded. All patients underwent general anesthesia and were positioned in dorsal recumbency. After an initial limited laparoscopic exploration, single-incision laparoscopic-assisted gastropexy was performed extracorporeally in all dogs via a conical port placed in a right paramedian location. Concurrent procedures included laparoscopic ovariectomy (n = 4), gastric biopsy (2), and castration (7). Short-term outcome was evaluated. RESULTS Median duration of surgery was 76 minutes (range, 40 to 90 minutes). Intraoperative complications were minor and consisted of loss of pneumoperitoneum in 2 of 14 dogs. A postoperative surgical site infection occurred in 1 dog and resolved with standard treatment. Median duration of follow-up was 371 days (range, 2 weeks to 1.5 years). No dogs developed gastric dilation-volvulus during the follow-up period, and all owners were satisfied with the outcome. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that single-incision laparoscopic-assisted gastropexy with a reusable conical port was feasible and effective in appropriately selected cases. Investigation of the potential benefits of this reusable port versus single-use devices for elective gastropexy in dogs is warranted.

Obstetric fistula is a worldwide problem that is devastating for women in developing countries. The cardinal cause of obstetric fistula is prolonged obstructed labour and delay in seeking emergency obstetric care. Awareness about obstetric fistula is still low in developing countries. The objective was to assess the awareness about risk factors of obstetric fistulae in rural communities of Nabitovu village, Iganga district, Eastern Uganda. A qualitative study using focus group discussion for males and females aged 18-49 years, to explore and gain deeper understanding of their awareness of existence, causes, clinical presentation and preventive measures for obstetric fistula. Data was analyzed by thematic analysis. The majority of the women and a few men were aware about obstetric fistula, though many had misconceptions regarding its causes, clinical presentation and prevention. Some wrongly attributed fistula to misuse of family planning, having sex during the menstruation period, curses by relatives, sexually transmitted infections, rape and gender-based violence. However, others attributed the fistula to delays to access medical care, induced abortions, conception at an early age, utilization of traditional birth attendants at delivery, and some complications that could occur during surgical operations for difficult deliveries. Most of the community members interviewed were aware of the risk factors of obstetric fistula. Some respondents, predominantly men, had misconceptions/myths about risk factors of obstetric fistula as being caused by having sex during menstrual periods, poor usage of family planning, being a curse.

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.

Perineal lacerations are common at the time of vaginal delivery and may predispose patients to long-term pelvic floor disorders, such as urinary incontinence and pelvic organ prolapse. Obstetric anal sphincter injuries, which are the most severe form of perineal lacerations, result in disruption of the anal sphincter and, in some cases, the rectal mucosa during vaginal delivery. Long-term morbidity, including pain, pelvic floor disorders, fecal incontinence, and predisposition to recurrent injury at subsequent delivery may result. Despite several studies that have reported risk factors for obstetric anal sphincter injuries, no accurate risk prediction models have been developed. The purpose of this study was to identify risk factors and develop prediction models for perineal lacerations and obstetric anal sphincter injuries. This was a nested case control study within a retrospective cohort of consecutive term vaginal deliveries at 1 tertiary care facility from 2004-2008. Cases were patients with any perineal laceration that had been sustained during vaginal delivery; control subjects had no lacerations of any severity. Secondary analyses investigated obstetric anal sphincter injury (3rd- to 4(th)-degree laceration) vs no obstetric anal sphincter injury (0 to 2(nd)-degree laceration). Baseline characteristics were compared between groups with the use of the chi-square and Student t test. Adjusted odds ratios and 95% confidence intervals were calculated with the use of multivariable logistic regression. Prediction models were created and model performance was estimated with receiver-operator characteristic curve analysis. Receiver-operator characteristic curves were validated internally with the use of the bootstrap method to correct for bias within the model. Of the 5569 term vaginal deliveries that were recorded during the study period, complete laceration data were available in 5524 deliveries. There were 3382 perineal lacerations and 249 (4.5%) obstetric anal

Accessory breasts have received little attention in the surgical fields, although the condition is quite common in the female population, with 2-6% of women suffering from it. Its convexity and cyclic pain make women feel embarrassed and uncomfortable, so patients often desire surgical excision to improve their appearances and to remove the pain. A total of 967 patients who had been treated by an excision of accessory breast tissue with liposuction using minimal incision from September 2013 to Dec 2015 at the Damsoyu Hospital were analyzed for clinical factors retrospectively. All 967 patients were female. There were 514 (53.2%) unmarried patients and 453 (46.8%) married patients. The major clinical manifestation was the problem in the appearance with cyclic pain in both unmarried and married groups (82.7 vs. 87.9%). Three types of accessory breasts were observed: 779 (80.6%) breast tissue only in axillae, 182 (18.8%) breast tissue with accessory nipple, and 6 (0.6%) breast tissue with accessory nipple-areolar complex. The mean operation time was 58 min. All cyclic axillar pain in our cases was resolved after the operation. Postoperative complications developed in 160 patients (16.55%). Among them, seroma after operation was the most common (11.27%). In our study, 95.65% of the patients were satisfied with the cosmetic outcomes. The surgical excision of accessory breasts with liposuction through the minimal incision is a safe and effective method to make women feel comfortable in clinical manifestations and be satisfied with their cosmetic axillar line.

In 1893, Wan Tsun-mo translated and published Tai chan ju yao ( Essentials in Obstetrics ), the first monograph of western obstetrics in modern China, symbolizing the independence of obstetrics from such maternal and child books as Fu ying xin shuo and Fu ke jing yun tu shuo , which occupies an important position in the history of the development of modern Chinese obstetrics. The book introduced anatomy, physiology, pathology, embryology, diagnostics, surgery, pharmacology and other knowledge of obstetrics in a catechismal form, and had a detailed discussion of such advanced obstetrical technologies as antiseptic, anesthesia, forceps and cesarean section for the first time.Judging from the content and translation of Tai chan ju yao , this book has already possessed the basic knowledge system of modern obstetrics, though the translation appeared to be somewhat jerky and not elegant and the terminology needing to be further improved, it was not only used as an important medium for the introduction of obstetrical knowledge, but also of great clinical value.However, its influence was so weak that later researchers seldom mentioned this book.

Patients with closed high-energy injuries associated with major trauma have surprisingly high rates of surgical site infection in incisions created during fracture fixation. One factor that may reduce the risk of surgical site infection is the type of dressing applied over the closed surgical incision. In this multicentre randomised clinical trial, negative-pressure wound therapy will be compared with standard dressings with outcomes of deep infection, quality of life, pain and disability. Adult patients presenting to hospital within 72 hours of sustaining major trauma, requiring a surgical incision to treat a fractured lower limb, are eligible for inclusion. Randomisation, stratified by trial centre, open/closed fracture at presentation and Injury Severity Score (ISS) ≤15 versus ISS ≥16 will be administered via a secure web-based service using minimisation. The random allocation will be to either standard wound management or negative-pressure wound therapy.Trial participants will usually have clinical follow-up at the local fracture clinic for a minimum of 6 months, as per standard National Health Service practice. Diagnosis of deep infection will be recorded at 30 days. Functional, pain and quality of life outcome data will be collected using the Disability Rating Index, Douleur Neuropathique Questionnaire and Euroqol - 5 Dimension - 5 level (EQ-5D-5L) questionnaires at 3 months and 6 months postinjury. Further data will be captured on resource use and any late postoperative complications.Longer term outcomes will be assessed annually for 5 years and reported separately. National Research Ethics Committee approved this study on 16 February 2016 16/WM/0006.The National Institute for Health Research Health Technology Assessment monograph and a manuscript to a peer-reviewed journal will be submitted on completion of this trial. The results of this trial will inform clinical practice on the clinical and cost-effectiveness of the treatment of this injury

Specialty procedures constitute one eighth of rural surgery practice. Currently, general surgeons intending to practice in rural hospitals may not get adequate training for specialty procedures, which they will be expected to perform. Better definition of these procedures will help guide rural surgery training. Current Procedural Terminology codes for all surgical procedures for 81% of North Dakota and South Dakota rural surgeons were entered into the Dakota Database for Rural Surgery. Specialty procedures were analyzed and compared with the Surgical Council on Resident Education curriculum to determine whether general surgery training is adequate preparation for rural surgery practice. The Dakota Database for Rural Surgery included 46,052 procedures, of which 5,666 (12.3%) were specialty procedures. Highest volume specialty categories included vascular, obstetrics and gynecology, orthopedics, cardiothoracic, urology, and otolaryngology. Common procedures in cardiothoracic and vascular surgery are taught in general surgical residency, while common procedures in obstetrics and gynecology, orthopedics, urology, and otolaryngology are usually not taught in general surgery training. Optimal training for rural surgery practice should include experience in specialty procedures in obstetrics and gynecology, orthopedics, urology, and otolaryngology. Copyright © 2012 Elsevier Inc.

2011-01-01

Atrophic edentulous mandible fractures in geriatric patients have low incidence but present several biological and biomechanical peculiarities that produce a nonunion rate of around 20%. Surgical extraoral approaches for internal fixation of these fractures can be transcervical or by one or two submandibular incisions. Two patients sustaining multiple fractures in atrophic edentulous mandible are presented: the first patient was 72-years-old, treated by two submandibular incisions, and the second was 81-years-old, treated by transcervical approach. We discuss the advantages and drawbacks of each approach and their indications according to the Luhr et al (1996) atrophy index. PMID:22379503

Extended cervico-thoracic metastasectomy for testicular non-seminomatous germ cell tumour masses through an inverse T and combined collar incision.

Non-seminomatous germ cell tumours (NSGCT) are the most common malignancy from testicular origin in young males. They are characterized by early formation of metastases along retroperitoneal and subsequent mediastinal lymph node stations. Following cisplatin-based induction chemotherapy, residual tumour masses should be removed surgically, although this implies the need for extended procedures. Such an approach can result in cure rates of over 70%. Herein, we report 2 cases of maximally extended surgery for metastatic malignant germ cell tumour of the testis. In both patients, diagnostic work-up revealed a NSGCT with retroperitoneal, mediastinal and cervical lymph node metastases. Multimodal protocols including induction chemotherapy and surgical removal of all primary and secondary tumour masses with curative intent were applied. An 'inverse T' incision in combination with a collar incision was chosen to approach the excessive supra-diaphragmatic tumour spread. This large-scaled surgical access offered an excellent exposure and allowed complete resection of all cervical and thoracic metastases in both patients. Abdominal tumour masses were resected through a standard median laparotomy. These 2 cases illustrate that complete tumour resection is feasible even in stages of NSGCT with generalized lymphatic spread. Metastasectomy should be offered to NSGCT patients despite the necessity of extended surgical approaches. © The Author 2014.

To determine whether a simple method for applying fibrin tissue adhesive to a clear corneal cataract incision can create a watertight seal. Laboratory investigation. Clear corneal cataract incisions were simulated in 8 eye-bank eyes. In 4 eyes, fibrin adhesive was applied to the incision in a simple manner; the other 4 eyes were controls with no adhesive. Each eye was tested under low pressure conditions to detect fluid ingress of India Ink on the eye's surface. The eyes were tested again with external compression to distort the incision to detect fluid egress. In the eyes with fibrin adhesive, there was no egress of fluid with incision distortion and no ingress of India Ink. In the 4 eyes without adhesive, there was ingress and egress of fluid. A simple method of applying fibrin adhesive to cataract incisions created a watertight seal.

Abstract Backgrounds: The harvesting of great saphenous veins for coronary artery bypass graft (CABG) patients may result in significant complications, including lymphorrhagia, lymphoedema, incision infection, wound dehiscence, and skin flap necrosis. We investigated the function of a self-designed bilayered negative pressure wound therapy (b-NPWT) for reducing the above-mentioned complications using a clinical randomized controlled trial. Methods: A single-center, pilot randomized controlled trial was conducted. From December 2013 to March 2014, a total of 72 coronary heart disease patients (48 men and 24 women) received CABG therapy, with great saphenous veins were selected as grafts. Patients were equally randomized into a treatment and a control group. After the harvesting of the great saphenous veins and direct closure of the wound with sutures, b-NPWT was used for the thigh incision in the treatment group for 5 days (treatment thigh). Traditional surgical pads were applied to both the shank incisions of the treatment group patients (treatment shank) and the entire incisions of the control group (control thigh, control shank). Postoperative complications were recorded and statistically analyzed based on outcomes of thigh treatment, shank treatment, thigh control, and shank control groups. Results: The incidence rates of early complications, such as lymphorrhagia, lymphoedema, infection, wound dehiscence, and skin flap necrosis, of the vascular donor site in the thigh treatment group was significantly lower than those in the 3 other groups. Conclusions: The self-designed b-NPWT can effectively reduce postoperative complications, such as lymphedema, incision infection, wound dehiscence, and skin flap necrosis, in CABG patients who underwent great saphenous veins harvesting. Trial registration: ClinicalTrials.gov. The unique registration number is NCT02010996. PMID:28099357

There are little primary data available on the delivery or quality of surgical treatment in rural sub-Saharan African hospitals. To initiate a quality improvement system, we characterized the existing data capture at a Ugandan Regional Referral Hospital. We examined the surgical ward admission (January 2008-December/2011) and operating theater logbooks (January 2010-July 2011) at Mbarara Regional Referral Hospital. There were 6346 admissions recorded over three years. The mean patient age was 31.4 ± 22.3 years; 29.8 % (n = 1888) of admissions were children. Leading causes of admission were general surgical problems (n = 3050, 48.1 %), trauma (n = 2041, 32.2 %), oncology (n = 718, 11.3 %) and congenital condition (n = 193, 3.0 %). Laparotomy (n = 468, 35.3 %), incision and drainage (n = 188, 14.2 %) and hernia repair (n = 90, 6.8 %) were the most common surgical procedures. Of 1325 operative patients, 994 (75 %) had an ASA I-II score. Of patients undergoing 810 procedures booked as non-elective, 583 (72 %) had an ASA "E" rating. Records of 41.3 % (n-403/975) of patients age 5 years or older undergoing non-obstetric operations were missing from the ward logbook. Missing patients were younger (25 [13,40] versus 30 [18,46] years, p = 0.002) and had higher ASA scores (ASA III-V 29.0 % versus 18.9 %, p < 0.001) than patients recorded in the logbbook; there was no diffence in gender (male 62.8 % versus 67.0 %, p = 0.20). The hospital records system measures surgical care, but improved data capture is needed to determine outcomes with sufficient accuracy to guide and record expansion of surgical capacity.

Therapeutic advances: Single incision laparoscopic hepatopancreatobiliary surgery

Chang, Stephen Kin Yong; Lee, Kai Yin

2014-01-01

Single-port laparoscopic surgery (SPLS) is proposed to be a step towards minimizing the invasiveness of surgery, and has since gained popularity in several surgical sub-specialties including hepatopancreatobiliary surgery. SPLS has since been applied to cholecystectomy, liver resection as well as pancreatectomy for a multitude of pathologies. Benefits of SPLS over conventional multi-incision laparoscopic surgery include improved cosmesis and potentially post-operative pain at specific time periods and extra-umbilical sites. However, it is also associated with longer operating time, increased rate of complications, and increased rate of port-site hernia. There is no significant difference between length of hospital stay. SPLS has a significant learning curve that affects operating time, rate of conversion and rate of complications. In this article, we review the literature on SPLS in hepatobiliary surgery - cholecystectomy, hepatectomy and pancreatectomy, and offer tips on overcoming potential technical obstacles and minimizing the complications when performing SPLS - surgeon position, position of port and instruments, instrument crossing position, standard hand grip vs reverse hand grip, snooker cue guide position, prevention of incisional hernia. SPLS is a promising direction in laparoscopic surgery, and we recommend step-wise progression of applications of SPLS to various hepatopancreatobiliary surgeries to ensure safe adoption of the surgical technique.

2012-01-01

The incidence of ureteral lesions varies between 0.1% and 30% depending on the type of the surgical intervention. However, the surgical interventions in Obstetrics and Gynecology are responsible for 50% of the total iatrogenic ureteral lesions. Sadly, only 1/3 of the iatrogenic ureteral lesions are recognized during surgeries and 25% of the unrecognized cases of ureteral lesions lead towards the loss of the damaged kidney, while a delayed diagnostic may also lead to a progressive deterioration of the renal function. On this matter, of decreasing the rate of morbidity and the following forensic risks, the gynecologist surgeon must be able to anticipate the potential apparition of a specific ureteral lesion, based on the known risk factors of the patient, so that he can then prevent the iatrogenic ureteral lesion.

2016-01-01

Objectives Obstetric fistula is a maternal injury that causes uncontrollable leaking of urine or stool, and most women who develop it live in poverty in low-income countries. Obstetric fistula is associated with high rates of stigma and psychological morbidity, but there is uncertainty about the impact of surgical treatment on psychological outcomes. The objective of this exploratory study was to examine changes in psychological symptoms following surgical fistula repair, discharge and reintegration home. Methods Women admitted for surgical repair of obstetric fistula were recruited from a Tanzanian hospital serving a rural catchment area. Psychological symptoms and social functioning were assessed prior to surgery. Approximately 3 months after discharge, a data collector visited the patients' homes to repeat psychosocial measures and assess self-reported incontinence. Baseline to follow-up differences were measured with paired t tests controlling for multiple comparisons. Associations between psychological outcomes and leaking were assessed with t tests and Pearson correlations. Results Participants (N = 28) had been living with fistula for an average of 11 years. Baseline psychological distress was high, and decreased significantly at follow-up. Participants who self-reported continued incontinence at follow-up endorsed significantly higher PTSD and depression symptoms than those who reported being cured, and severity of leaking was associated with psychological distress. Conclusions Fistula patients experience improvements in mental health at 3 months after discharge, but these improvements are curtailed when women experience residual leaking. Given the rate of stress incontinence following surgery, it is important to prepare fistula patients for the possibility of incomplete cure and help them develop appropriate coping strategies.

Objectives Obstetric fistula is a maternal injury that causes uncontrollable leaking of urine or stool, and most women who develop it live in poverty in low-income countries. Obstetric fistula is associated with high rates of stigma and psychological morbidity, but there is uncertainty about the impact of surgical treatment on psychological outcomes. The objective of this exploratory study was to examine changes in psychological symptoms following surgical fistula repair, discharge and reintegration home. Methods Women admitted for surgical repair of obstetric fistula were recruited from a Tanzanian hospital serving a rural catchment area. Psychological symptoms and social functioning were assessed prior to surgery. Approximately 3 months after discharge, a data collector visited the patients' homes to repeat psychosocial measures and assess self-reported incontinence. Baseline to follow-up differences were measured with paired t tests controlling for multiple comparisons. Associations between psychological outcomes and leaking were assessed with t tests and Pearson correlations. Results Participants (N = 28) had been living with fistula for an average of 11 years. Baseline psychological distress was high, and decreased significantly at follow-up. Participants who self-reported continued incontinence at follow-up endorsed significantly higher PTSD and depression symptoms than those who reported being cured, and severity of leaking was associated with psychological distress. Conclusions Fistula patients experience improvements in mental health at 3 months after discharge, but these improvements are curtailed when women experience residual leaking. Given the rate of stress incontinence following surgery, it is important to prepare fistula patients for the possibility of incomplete cure and help them develop appropriate coping strategies.

This study aimed to investigate whether celastrol (CEL) could alleviate incision-induced pain and decipher its possible mechanism. Sprague-Dawley rats were randomly divided into five groups: naïve, vehicle, CEL (5 μg/paw, 10 μg/paw and 20 μg/paw). CEL or vehicle was administered intraplantarly before plantar surgical incision. Histological examinations of skin tissues were performed after HE staining. Additionally, immunohistochemical staining, RT-PCR and western blot were performed to analyse macrophages, proinflammatory cytokines, SARM and NF-κB expression, respectively. Moreover, the previous mentioned factors were re-evaluated after suppressing SARM expression by shRNA. The plantar incision rats displayed pain-related behaviours and inflammatory infiltration in the skin. The mRNA levels of proinflammatory cytokines, such as IL-1β, IL-6, and TNFα were significantly upregulated in the skin of surgical rats. The expression of sterile α- and armadillo-motif-containing protein (SARM) was downregulated and nuclear factor kappa-B (NF-κB) was activated. Interestingly, CEL could partially restore the pain-related behavioural changes. Furthermore, molecular mechanism of CEL was explored, that included significantly reduction of proinflammatory cytokines mRNA expressions, a significant decrease of p-p65 and p65 levels and a markedly increase of SARM and IkBα expressions in skin tissues. However, supression SARM by shRNA partially eliminated those protective effect of CEL. Our data suggest that intraplantarly administration of CEL attenuates inflammatory and acute pain. This finding could be attributed to regulation of the NF-κB signalling pathway via SARM. These results provide pre-clinical evidence supporting the use of CEL in the treatment of surgical pain.

Background Focal cartilage lesions in the knee joint have limited capacity to heal. Current animal experiments show that incisions of the deep zone of a cartilage allograft allow acceptable integration for the graft. Questions/Purposes We performed this clinical study to determine (1) if the multiply incised cartilage graft is surgically applicable for focal cartilage lesions, (2) whether this allograft has a potential to integrate to the repair site, and (3) if patients show clinical improvement. Patients and Methods Seven patients with 8 chondral lesions were enrolled into the study. Symptomatic lesions between 2 and 8 cm2 were accepted. Additional injuries were allowed but were addressed simultaneously. Grafts were tailored to match and the deep zone of the cartilage was multiply incised to augment the basal integration before securing in place. Rigorous postoperative physiotherapy followed. At 12 and 24 months the patients’ satisfaction were measured and serial magnetic resonance imaging (MRI) was performed in 6 patients. Results Following the implantations no adverse reaction occurred. MRI evaluation postoperatively showed the graft in place in 5 out of 6 patients. In 1 patient, MRI suggested partial delamination at 1 year and graft degeneration at 2 years. Short Form–36 health survey and the Lysholm knee score demonstrated a significant improvement in the first year; however, by 2 years there was a noticeable drop in the scores. Conclusions. Multiply incised pure chondral allograft used for cartilage repair appears to be a relatively safe method. Further studies are necessary to assess its potential in cartilage repair before its clinical use. PMID:26069710

To examine the status of resident training in robotic surgery in obstetrics and gynecology programs in the United States, an online survey was emailed to residency program directors of 247 accredited programs identified through the Accreditation Council for Graduate Medical Education website. Eighty-three of 247 program directors responded, representing a 34% response rate. Robotic surgical systems for gynecologic procedures were used at 65 (78%) institutions. Robotic surgery training was part of residency curriculum at 48 (58%) residency programs. Half of respondents were undecided on training effectiveness. Most program directors believed the role of robotic surgery would increase and play a more integral role in gynecologic surgery. Robotic surgery was widely reported in residency training hospitals with limited availability of effective resident training. Robotic surgery training in obstetrics and gynecology residency needs further assessment and may benefit from a structured curriculum. Published by Elsevier Inc.

Scar retraction due to exposed bone in palatoplasty is the leading cause of constricted maxilla. Modern techniques have focused on minimizing the effects of scarring by reducing the exposure of the bone area. The objective of the study was to compare the palatal mucoperiosteal detachment with minimal lateral incision, followed by their synthesis, with the maintenance of lateral areas for relaxation (similar to the von Langenbeck technique) and evaluate the transversal development of the maxilla. A prospective, randomized study was conducted, in which the molding of the dental arch of 14 pigs in 2 stages (at 1 month and 5 months) was performed. The pigs were divided into 3 groups: group 1 underwent lateral incision of the palate for mucoperiosteal detachment and maintenance of bone exposure; group 2 underwent mucoperiosteal palatal detachment with lateral access and no bone exposure; and group 3, the control animals, did not undergo any surgical procedures. Measurements of the dental arches were compared between the groups to assess differences in the development of the maxillary transverse diameter. There were no animals lost during the study. Group 1 showed greater growth restriction of the transverse diameter of the maxilla (36%) when compared with groups 2 (56%) and 3 (59%). Groups 2 and 3 showed similar transverse maxillary development, with no statistical difference. The technique of mucoperiosteal detachment without lateral relief incision has the advantage of reducing future morbidity of a constricted maxilla. This study demonstrated that the technique described can reduce rates of maxillary underdevelopment, a significant complication inherent in the procedure for palatoplasty. The lateral incisions reduce maxillary growth by approximately 20% as compared with this technique. Level II of evidence.

BACKGROUND Currently, safe and effective surgical treatment of malignant glaucoma is still under investigation. This study evaluated the clinical efficacy of ciliary ring incision combined with modified partial pars plana vitrectomy in the treatment of malignant glaucoma. The technique is particularly useful in the treatment of "phakic" patients with malignant glaucoma, especially those who wish to preserve the natural lens. MATERIAL AND METHODS We retrospectively analyzed 13 cases (16 eyes) of malignant glaucoma in which patients underwent ciliary ring incision combined with modified partial pars plana vitrectomy based on follow-up data collected from May 2004 to March 2017. The data we analyzed included postoperative best-corrected visual acuity(BCVA), intraocular pressure (IOP), anterior chamber depth (ACD), optic cup changes, and surgical complications; some patients underwent visual field tracking. The mean follow-up period was 33.1±10.6 (range, 19-46) months. RESULTS A statistically significant number of eyes had improved visual acuity 1 year after surgery compared with the preoperative difference (Z=-3.853, P=0.000). Increases in the mean anterior chamber depth and decreases in the mean IOP measured at the 1-week and the 1-year follow-ups were also statistically significant. There were no serious complications during the follow-up period. CONCLUSIONS Ciliary ring incision combined with modified partial pars plana vitrectomy for malignant glaucoma not only provided a clear and reliable intraoperative vitrectomy channel, but it also caused less disturbance of intraocular tissue structure and fewer complications. It also has the advantage of preserving the lens and avoiding further damage to the anatomy in the anterior segment of the eye.

To characterize the rate of obstetric anal sphincter injuries and identify key risk factors of obstetric anal sphincter injuries, including duration of the second stage of labor. This retrospective cohort study included all singleton, term, cephalic vaginal deliveries within Kaiser Permanente Northern California between January 2013 and December 2014 (N=22,741). Incidence of obstetric anal sphincter injuries, defined as third- or fourth-degree perineal lacerations, was the primary outcome. Multiple logistic regression models were conducted to identify obstetric anal sphincter injury risk factors and high-risk subpopulations. The overall incidence rate of obstetric anal sphincter injuries was 4.9% (3.6% of women who delivered spontaneously vs 24.0% of women who had a vacuum-assisted vaginal delivery, P<.001, CI 18.1-22.6%). In bivariate and multivariate analyses, obstetric anal sphincter injury incidence was higher among women with second stage of labor longer than 2 hours, Asian race, nulliparity, vaginal birth after cesarean delivery, episiotomy, and vacuum delivery. Women with a vacuum-assisted vaginal delivery had four times the odds of obstetric anal sphincter injury (adjusted odds ratio [OR] 4.23, 95% CI 3.59-4.98) and those whose second stage of labor lasted at least 180 minutes vs less than 60 minutes had three times the odds of incurring obstetric anal sphincter injury (adjusted OR 3.20, 95% CI 2.62-3.89). Vacuum-assisted vaginal delivery conferred the highest odds of obstetric anal sphincter injury followed by prolonged duration of the second stage of labor, particularly among certain subpopulations. Understanding these risk factors and their complex interactions can inform antepartum and intrapartum decision-making with the goal of reducing obstetric anal sphincter injury incidence.

To determine the accuracy of the Lindstrom surgical nomogram for astigmatism. A prospective multicenter study. One hundred sixty eyes of 95 patients underwent astigmatic keratotomy in eight centers by nine surgeons. Inclusion criteria for the study included age of at least 18 years with 1 to 6 diopters (D) of naturally occurring corneal astigmatism and less than 1 D of lenticular astigmatism. A standardized astigmatic keratotomy surgical technique was performed on each eye. Surgical measurements were determined using the Lindstrom surgical nomogram for astigmatism. The Holladay, Cravy, Koch vector analysis method was used to determine the change in refractive cylinder results. Refractive changes also are presented without vector analysis merely using the absolute change in refractive cylinder and axis. Multiple regression analysis was used to develop a mathematical model determining the factors predictive of the change in refractive cylinder. The significant predictors for the amount of astigmatic correction achieved were, in order of decreasing importance, the following: number of incisions (R2 = 30%), incision length (R2 = 16%), age (R2 = 8%), and gender (R2 = 2%). Astigmatism is a two-dimensional measurement of both quantity and direction that is most appropriately analyzed with vector analysis. The original Lindstrom surgical nomogram for arcuate keratotomy used in this study is still quite useful although it tended to underpredict results for many patients, especially those having two incisional surgeries. Some older subjects having minimal surgery achieved greater correction than predicted by the original nomogram. The most important factors predictive of greater astigmatic keratotomy surgical effect are incision number, incision length, older age, and male gender.

Acute abdomen is a rare entity in the pregnant patient, with an incidence of one in 500-635 patients. Its appearance requires a quick response and an early diagnosis to treat the underlying disease and prevent maternal and fetal morbidity. Imaging tests are essential, due to clinical and laboratory masking in this subgroup. Appendicitis and complicated biliary pathology are the most frequent causes of non-obstetric acute abdomen in the pregnant patient. The decision to operate, the timing, and the surgical approach are essential for a correct management of this pathology. The aim of this paper is to perform a review and update on the diagnosis and treatment of non-obstetric acute abdomen in pregnancy. Copyright © 2015 AEC. Publicado por Elsevier España, S.L.U.

Results of prospective randomized comparative research of 2 total hemoglobin estimation methods are presented. There were laboratory tests and continuous noninvasive technique with multiwave spectrophotometry on the Masimo Rainbow SET. Research was carried out in two stages. At the 1st stage (gynecology)--67 patients were included and in second stage (obstetrics)--44 patients during and after Cesarean section. The standard deviation of noninvasive total hemoglobin estimation from absolute values (invasive) was 7.2 and 4.1%, an standard deviation in a sample--5.2 and 2.7 % in gynecologic operations and surgical delivery respectively, that confirms lack of reliable indicators differences. The method of continuous noninvasive total hemoglobin estimation with multiwave spectrophotometry on the Masimo Rainbow SET technology can be recommended for use in obstetrics and gynecology.

Abstract Objectives To explore the effects of the students' gender on their perception of quality and quantity of teaching, the amount of experiential learning, and their interest in obstetrics and gynecology. Methods Anonymous, self-administered surveys to third-year medical students rotating on the obstetrics and gynecology clerkship. Results Eighty-one of 91 students participated (89% response rate): 33 men, 46 women, 2 declined to reveal their gender. No significant gender differences existed regarding number of interactions with residents and faculty; number of deliveries, surgeries, or examinations performed; perceived quality of teaching; or feeling included as part of the clinical team. Male students were more likely to report performing specific surgical procedures, such as operating the bovie cautery during gynecological surgeries (p = 0.005). More men experienced patients refusing to allow them to participate in the clinical interview (p < 0.0001) and physical examination (p < 0.0001). Male students were also more likely to report feeling that their gender negatively impacted their clerkship experience (p < 0.0001). Although less likely to report preclerkship and postclerkship career interest in obstetrics and gynecology, male students were more likely to report that their interest increased at the end of the clerkship. Conclusions Male students were more likely to experience gender bias from patients on the obstetrics and gynecology service. Male students also described feeling socially excluded from female-dominated clinical teams. Obstetrics and gynecology educators need to consider methods of encouraging patients to accept medical student participation regardless of gender. Obstetrics and gynecology faculty and residents need to be sensitive to subtle forms of gender bias and ensure equal inclusion for both male and female medical students. PMID:20088663

Evidence-based guidelines for the prevention of surgical site infection (SSI) have been published by the U.S. Centers for Disease Control and Prevention (CDC). According to these guidelines, a wound should usually be covered with a sterile dressing for 24 to 48 h when a surgical incision is closed primarily. However, it is not recommended that an incision be covered by a dressing beyond 48 h. In this study, patients were stratified into two groups for analysis: patients whose surgical wound was sterilized and whose gauze was changed once daily until postoperative day 7 (7POD; group A); and patients whose surgical wound was sterilized and whose gauze was changed once daily until 2POD (group B). We evaluated the incidence of SSI, nursing hours and cost implications. The results showed that there was no significant difference in SSI occurrence between the two groups (group A, 10% vs. group B, 7.3%). By contrast, the average nursing time differed by 2.8 min (group A, 3.8 min vs. group B, 0.9 min). The material costs per patient were also reduced by $14.70 (group A, $61.80 vs. group B, $47.10). In conclusion, we applied our knowledge of the evidence-based CDC guidelines to determine whether 48-h wound management can be made easier, more uniform and more cost-effective compared to conventional wound management. The results of the present study showed that surgical wound management methods can be more convenient and inexpensive.

Plantar Fascia Release Through a Single Lateral Incision in the Operative Management of a Cavovarus Foot: A Cadaver Model Analysis of the Operative Technique.

2018-04-04

Plantar fascia release and calcaneal slide osteotomy are often components of the surgical management for cavovarus deformities of the foot. In this setting, plantar fascia release has traditionally been performed through an incision over the medial calcaneal tuberosity, and the calcaneal osteotomy through a lateral incision. Two separate incisions can potentially increase the operative time and morbidity. The purpose of the present study was threefold: to describe the operative technique, use cadaveric dissection to analyze whether a full release of the plantar fascia was possible through the lateral incision, and examine the proximity of the medial neurovascular structures to both the plantar fascia release and calcaneal slide osteotomy when performed together. In our cadaveric dissections, we found that full release of the plantar fascia is possible through the lateral incision with no obvious damage to the medial neurovascular structures. We also found that the calcaneal branch of the tibial nerve reliably crossed the osteotomy in all specimens. We have concluded that both the plantar fascia release and the calcaneal osteotomy can be safely performed through a lateral incision, if care is taken when completing the calcaneal osteotomy to ensure that the medial neurovascular structures remain uninjured.

Purpose To evaluate the impact of surgical factors such as incision type, number of sutures, and technique of closure on postoperative astigmatism in infants undergoing cataract extraction with or without intraocular lens implantation. Methods The IATS is a multicenter (n=12) clinical trial in which 114 infants with unilateral congenital cataracts were randomized to undergo cataract extraction with intraocular lens (IOL) placement or contact lens aphakic correction. Surgical videos were reviewed with regard to incision type and location, whether the incision was extended, the number of sutures placed, and technique of closure. Corneal astigmatism was measured using a handheld keratometer prior to surgery and at 1 year of age. Results Corneal astigmatism decreased from a mean of 1.92 D at baseline to 1.62 D at age 1 year in the CL group, but remained almost unchanged from 2.00 D to 2.09 D in the IOL group (p=0.023). There was no statistical difference between the amount of corneal astigmatism irrespective of incision type (p=0.214) and no increase in astigmatism with extension of the incision to facilitate IOL placement (p=0.849) at 1 year. The number of sutures and technique of closure did not influence the amount of astigmatism at 1 year. Conclusions At the age of one year following cataract extraction in infants, contact lens correction and the lack of IOL placement are associated with a significant decrease in postoperative corneal astigmatism compared to intraocular lens placement. No other surgical factors considered in this study had a statistically significant impact on corneal astigmatism. PMID:25266831

Context It has long been a concern that professional liability problems disproportionately affect the delivery of obstetrical services to women living in rural areas. Michigan, a state with a large number of rural communities, is considered to be at risk for a medical liability crisis. Purpose This study examined whether higher malpractice burden on obstetric providers was associated with an increased likelihood of discontinuing obstetric care and whether there were rural-urban differences in the relationship. Methods Data on 500 obstetrician-gynecologists and family physicians who had provided obstetric care at some point in their career (either currently or previously) were obtained from a statewide survey in Michigan. Statistical tests and multivariate regression analyses were performed to examine the interrelationship among malpractice burden, rural location, and discontinuation of obstetric care. Findings After adjusting for other factors that might influence a physician’s decision about whether to stop obstetric care, our results showed no significant impact of malpractice burden on physicians’ likelihood to discontinue obstetric care. Rural-urban location of the practice did not modify the nature of this relationship. However, family physicians in rural Michigan had a nearly four fold higher likelihood of withdrawing obstetric care when compared to urban family physicians. Conclusions The higher likelihood of rural family physicians to discontinue obstetric care should be carefully weighed in future interventions to preserve obstetric care supply. More research is needed to better understand the practice environment of rural family physicians and the reasons for their withdrawal from obstetric care. PMID:19166559

Morphodynamic Model of Submarine Canyon Incision by Sandblasting

Submarine canyons are carved by turbidity currents under the deep sea. As opposed to subaerial canyons, the relevant processes are not easy to observe directly. Turbidity currents are bottom-hugging sediment gravity flows of that can incise or deposit on the seafloor to create submarine canyons or fans. The triggers of turbidity currents can be storms, edge waves, internal waves, canyon wall sapping, delta failure, breaching and hyperpycnal flows. The formation and evolution mechanisms of submarine canyons are similar to those of subaerial canyons, but have substantial differences. For example, sandblasting, rather than wear due to colliding gravel clasts is more likely to be the mechanism of bedrock incision. Submarine canyons incise downward, and often develop meander bends and levees within the canyon, so defining "fairways". Here we propose a simple model for canyon incision. The starting point of our model is the Macro Roughness Saltation Abrasion Alluviation model of Zhang et al. [2015], designed for bedrock incision by gravel clasts in mixed bedrock-alluvial rivers. We adapt this formulation to consider sandblasting as a means of wear. We use a layer-averaged model for turbidity current dynamics. The current contains a mixture of mud, which helps drive the flow but which does not cause incision, and sand, which is the agent of incision. We show that the model can successfully model channel downcutting, and indeed illustrate the early formation of net incisional cyclic steps, i.e. upstream-migrating undulations on the bed associated with transcritical (in the Froude sense) flow. These steps can be expected to abet the process of incision.

Rapid incision of the Colorado River in Glen Canyon - insights from channel profiles, local incision rates, and modeling of lithologic controls

The Colorado River system in southern Utah and northern Arizona is continuing to adjust to the baselevel fall responsible for the carving of the Grand Canyon. Estimates of bedrock incision rates in this area vary widely, hinting at the transient state of the Colorado and its tributaries. In conjunction with these data, we use longitudinal profiles of the Colorado and tributaries between Marble Canyon and Cataract Canyon to investigate the incision history of the Colorado in this region. We find that almost all of the tributaries in this region steepen as they enter the Colorado River. The consistent presence of oversteepened reaches with similar elevation drops in the lower section of these channels, and their coincidence within a corridor of high local relief along the Colorado, suggest that the tributaries are steepening in response to an episode of increased incision rate on the mainstem. This analysis makes testable predictions about spatial variations in incision rates; these predictions are consistent with existing rate estimates and can be used to guide further studies. We also present cosmogenic nuclide data from the Henry Mountains of southern Utah. We measured in situ 10Be concentrations on four gravel-covered strath surfaces elevated from 1 m to 110 m above Trachyte Creek. The surfaces yield exposure ages that range from approximately 2??5 ka to 267 ka and suggest incision rates that vary between 350 and 600 m/my. These incision rates are similar to other rates determined within the high-relief corridor. Available data thus support the interpretation that tributaries of the Colorado River upstream of the Grand Canyon are responding to a recent pulse of rapid incision on the Colorado. Numerical modeling of detachment-limited bedrock incision suggests that this incision pulse is likely related to the upstream-dipping lithologic boundary at the northern edge of the Kaibab upwarp. ?? 2009 John Wiley & Sons, Ltd.

Pediatric obstetrical ethics: Medical decision-making by, with, and for pregnant early adolescents.

PubMed

Mercurio, Mark R

2016-06-01

Pregnancy in an early adolescent carries with it specific ethical considerations, in some ways different from pregnancy in an adult and from medical care of a non-pregnant adolescent. Obstetrical ethics emphasizes the right of the patient to autonomy and bodily integrity, including the right to refuse medical intervention. Pediatric ethics recognizes the right of parents, within limits, to make medical decisions for their children, and the right of a child to receive medical or surgical interventions likely to be of benefit to her, sometimes over her own objections. As the child gets older, and particularly during the years of adolescence, there is also a recognition of the right to an increasingly prominent role in decisions about her own healthcare. Pediatric obstetrical ethics, referring to ethical decisions made by, with, and for pregnant early adolescents, represents the intersection of these different cultures. Principles and approaches from both obstetrical and pediatric ethics, as well as a unified understanding of rights, obligations, and practical considerations, will be needed. Copyright © 2016.

Surgical Management of the Constricted or Obliterated Vagina.

Gebhart, John B; Schmitt, Jennifer J

2016-08-01

Management of the constricted or obliterated vagina demands an understanding and recognition of the potential etiologies leading to this presentation. A thorough and comprehensive medical and surgical review is required to arrive at an accurate diagnosis, which then will guide medical or surgical intervention. It is paramount to recognize when underlying medical conditions are contributing to these conditions and to begin medical therapy; failure to do so will often yield suboptimal results. When these conditions arise after surgical interventions, compensatory surgical techniques that correct upper and lower vaginal strictures or obliteration include incision through the stricture, vaginal advancement, Z-plasty, skin grafts, perineal flaps, and abdominal flaps and grafts. Postoperative surveillance and dilation are critical to optimize long-term success.

Although surgical outcomes of total arch replacement have improved, the strategy for extended arch aneurysms remains controversial. We have applied the L-incision approach (combination of left anterior thoracotomy and upper half-median sternotomy) for total arch replacement for single-stage repair of extensive arch aneurysms. We retrospectively reviewed the operative outcomes of patients who underwent total arch or extended total arch replacement for degenerative aneurysms from 1999 to 2010. Operations were performed via median sternotomy in 47 patients (M group) and the L-incision approach was used in 38 patients (L group). Through the L-incision approach, we were able to complete distal anastomosis below the pulmonary hilus. The L-incision approach has advantages of reducing selective antegrade cerebral perfusion and lower body circulatory arrest times compared with the M group. Recurrent laryngeal nerve palsy and renal dysfunction were less frequent in the L group than those in the M group. Respiratory dysfunction and wound infection were similar between the groups. Hospital mortalities were 5.3% in the L group and 6.4% in the M group. The L-incision approach has similar or better postoperative outcomes compared with the median sternotomy approach. This approach could be useful for single-stage extended total arch replacement with relatively low risk.

To handle physical interaction between the surgical tools and organs, we propose a simple surface-constraint-based manipulation algorithm to consistently simulate common surgical manipulations such as grasping, holding and retraction. Our computation model is capable of simulating soft-tissue deformation and incision in real time. We also present visualization techniques in order to rapidly visualize time-varying, volumetric information on the deformed image. This paper demonstrates the success of the proposed methods in enabling the simulation of surgical processes, and the ways in which this simulation facilitates preoperative planning and rehearsal.

This case report is presented to assess safety and efficiency of early suction and saline washout of extravasated cytotoxic drugs. Through multiple small skin incisions, the area of extravasation is first suctioned and subsequently extensively washed out with saline. Incisions are left open and the arm is elevated for 24 hours. A complete healing was obtained in five days without any skin or soft tissue loss. No additional treatment was needed. Early referral and surgical treatment by suction and washout is a safe and reliable treatment protocol for major cytotoxic drug extravasation injuries.

Postoperative nausea and vomiting (PONV) affect approximately 80% of surgical patients and is associated with increased length of hospital stay and systemic costs. Preoperative and postoperative pain, anxiety and depression are also commonly reported. Recent evidence regarding their safety and effectiveness has not been synthesised. The aim of this systematic review is to evaluate the efficacy and safety of herbal medications for the treatment and prevention of anxiety, depression, pain and PONV in patients undergoing laparoscopic, obstetrical/gynaecological and cardiovascular surgical procedures. The following electronic databases will be searched up to 1 October 2016 without language or publication status restrictions: CENTRAL, MEDLINE, EMBASE, CINAHL, Web of Science and LILACS. Randomised clinical trials enrolling adult surgical patients undergoing laparoscopic, obstetrical/gynaecological and cardiovascular surgeries and managed with herbal medication versus a control group (placebo, no intervention or active control) prophylactically or therapeutically will be considered eligible. Outcomes of interest will include the following: anxiety, depression, pain, nausea and vomiting. A team of reviewers will complete title and abstract screening and full-text screening for identified hits independently and in duplicate. Data extraction, risk of bias assessments and evaluation of the overall quality of evidence for each relevant outcome reported will be conducted independently and in duplicate using the Grading of Recommendations Assessment Development and Evaluation classification system. Dichotomous data will be summarised as risk ratios; continuous data will be summarised as standard average differences with 95% CIs. This is one of the first efforts to systematically summarise existing evidence evaluating the use of herbal medications in laparoscopic, obstetrical/gynaecological and cardiovascular surgical patients. The findings of this review will be disseminated

To compare the astigmatic correction in high myopic astigmatism between small-incision lenticule extraction and laser in situ keratomileusis (LASIK) using vector analysis. Hong Kong Laser Eye Center, Hong Kong. Retrospective case series. Patients who had correction of myopic astigmatism of 3.0 diopters (D) or more and had either small-incision lenticule extraction or femtosecond laser-assisted LASIK were included. Only the left eye was included for analysis. Visual and refractive results were presented and compared between groups. The study comprised 105 patients (40 eyes in the small-incision lenticule extraction group and 65 eyes in the femtosecond laser-assisted LASIK group.) The mean preoperative manifest cylinder was -3.42 D ± 0.55 (SD) in the small-incision lenticule extraction group and -3.47 ± 0.49 D in the LASIK group (P = .655). At 3 months, there was no significant between-group difference in uncorrected distance visual acuity (P = .915) and manifest spherical equivalent (P = .145). Ninety percent and 95.4% of eyes were within ± 0.5 D of the attempted cylindrical correction for the small-incision lenticule extraction and LASIK group, respectively (P = .423). Vector analysis showed comparable target-induced astigmatism (P = .709), surgically induced astigmatism vector (P = .449), difference vector (P = .335), and magnitude of error (P = .413) between groups. The absolute angle of error was 1.88 ± 2.25 degrees in the small-incision lenticule extraction group and 1.37 ± 1.58 degrees in the LASIK group (P = .217). Small-incision lenticule extraction offered astigmatic correction comparable to LASIK in eyes with high myopic astigmatism. Copyright © 2018 ASCRS and ESCRS. Published by Elsevier Inc.

The da Vinci(®) Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) is a computer-assisted (robotic) surgical system designed to enable and enhance minimally invasive surgery. The Food and Drug Administration (FDA) has cleared computer-assisted surgical systems for use by trained physicians in an operating room environment for laparoscopic surgical procedures in general, cardiac, colorectal, gynecologic, head and neck, thoracic and urologic surgical procedures. There are substantial numbers of peer-reviewed papers regarding the da Vinci(®) Surgical System, and a thoughtful assessment of evidence framed by clinical opinion is warranted. The SAGES da Vinci(®) TAVAC sub-committee performed a literature review of the da Vinci(®) Surgical System regarding gastrointestinal surgery. Conclusions by the sub-committee were vetted by the SAGES TAVAC Committee and SAGES Executive Board. Following revisions, the document was evaluated by the TAVAC Committee and Executive Board again for final approval. Several conclusions were drawn based on expert opinion organized by safety, efficacy, and cost for robotic foregut, bariatric, hepatobiliary/pancreatic, colorectal surgery, and single-incision cholecystectomy. Gastrointestinal surgery with the da Vinci(®) Surgical System is safe and comparable, but not superior to standard laparoscopic approaches. Although clinically acceptable, its use may be costly for select gastrointestinal procedures. Current data are limited to the da Vinci(®) Surgical System; further analyses are needed.

[Consequences of increasing and ageing population of Basse-Normandie on gynecology and obstetrics activity].

In Basse-Normandie, the population over 65 years old will expend more rapidly between 2007 and 2042 (+11.6%) than the rest of the French population (+9.2%). The same population of Basse-Normandie will get old in the 15 years to come. The impact of these demographic changes over the activity in the gynecology-obstetrics field is not clearly identified. Although we cannot predict the technical and scientific developments in the next 15 years, we are presenting a model allowing to hypothesize about changes of gynecology and obstetrics according to population's aging. We have established a projection model for the realizable surgical acts in obstetrics and gynecology in accordance with the aging of the population in Basse-Normandie. The study was realized based on the acts concerning the cesarean sections (C-section), tubal sterilization, hysteroscopy and hysterectomy as well as ovarectomy and breast surgery. For each activity branch, the codes of the Classification commune des actes médicaux (CCAM) were selected and then removed from the Programme médicalisé des systèmes d'information (PMSI) database. We have used and adapted the Omphale model of the National Statistics and Economical Studies Institute and we have applied it for the period of 2009-2025. Our projection model has permeated to show a 5.5% regression of the C-section acts, a 2% incretion of the hysterectomies and hysteroscopies, 7.7% of ovarectomies as well as a 9.8% augmentation of the breast surgeries. However, we predict a 11.8% diminution of the sterilizations by tubal implants. Globally, the activity in obstetrics and gynecology will remain constant with an insignificant augmentation of 46 acts (0.01%). In Basse-Normandie, the surgical activity in gynecology-obstetrics will moderately increase in the next 15 years. This constant activity signifies that there is no need to form more residents than the number of practitioner to retire. The interest of this model is that it is applicable at a

Subspecialization in gynecology and obstetrics: advantages and disadvantages.

PubMed

Ludwig, H

1991-08-20

To discuss the problem of subspecialization in our discipline is presently very popular. Whether or not a complete separation into the three subdisciplines: (1) materno-fetal medicine - obstetrics (2) surgical gynecology - gynecologic oncology (3) gynecologic endocrinology - reproductive medicine is recommended remains unclear in most of the statements. Some describe forms of only a supplementary postgraduate education, a kind of prolongation of the basic gynecologic and obstetrical training concentrated on one of the three main fields. The complete separation, i.e., in obstetrical medicine, reproductive medicine, gynecologic pelvic surgery, has the advantage of a more effective concentration on each of the respective subdisciplines in clinical work and in research. On the other hand, the separation will certainly produce several disadvantages: (a) What is inbetween the subdisciplines will be difficult to integrate. (b) The principle of the gynecologist functioning as a primary health care physician for women will be weakened, i.e., his competence for family-planning, pregnancy and delivery of normal cases, for cancer screening of genital and breast tumors, for disorders of the cycle, for pelvic inflammatory diseases and for the care of postmenopausal women will be less integral. (c) The lectures will be more than at present split or overloaded with detailed facts. (d) The need of general gynecologic care - as well cost-effective as widely available - will less frequently be met than now. (e) The opportunities for younger colleagues to settle with an office of their own will be restricted. The disadvantages outweigh the advantages.(ABSTRACT TRUNCATED AT 250 WORDS)

Appendicitis is the most common emergent problem encountered by pediatric surgeons. Driven by improved cosmetic outcomes, many surgeons are offering pediatric patients single-incision laparoscopic appendectomy. We sought to investigate the financial impact of different surgical approaches to appendectomy. A retrospective study of patients with acute appendicitis undergoing appendectomy from February 2010 to September 2011 was conducted. Based on surgeon preference, patients underwent open appendectomy (OA), laparoscopic appendectomy (LA), or single-incision laparoscopic appendectomy (SILA). Demographic information, surgical outcomes, surgical supply costs, and total direct costs were recorded. A total of 465 patients underwent appendectomy during the study. The mean age of all patients was 11.2 years (range, 1 to 18 years). There were no conversions in the LA or SILA groups. There was a significant difference among surgical technique in regard to surgical supply costs (OA $159 vs. LA $650 vs. SILA $814, P < 0.01) and total direct costs (OA $2129 vs. LA $2624 vs. SILA $2991, P < 0.01). In our institution, both multiport laparoscopic and SILA carry higher costs when compared with OA, largely as a result of the cost of disposable instrumentation. Cost efficiency should be considered by surgeons when undertaking a minimally invasive approach to appendectomy.

First experience with single incision laparoscopic surgery in Slovakia: concomitant cholecystectomy and splenectomy in an 11-year-old girl with hereditary spherocytosis.

Hereditary spherocytosis is an autosomal dominant inheritance disorder of the red blood cell membrane characterized by the presence of spherical-shaped erythrocytes (spherocytes) in the peripheral blood. The main clinical features include haemolytic anemia, variable jaundice, splenomegaly and cholelithiasis caused by hyperbilirubinemia from erythrocyte hemolysis. Splenectomy does not solve the congenital genetic defect but it stops pathological hemolysis in the enlarged spleen. If gallstones are present, it is appropriate to perform cholecystectomy at the time of splenectomy, although the patient has symptoms of gall bladder disease. We present the case of single incision laparoscopic surgical (SILS) concomitant splenectomy and cholecystectomy performed with conventional laparoscopic instruments in an 11-year-old girl with the diagnosis of hereditary spherocytosis. A 2-3 cm umbilical incision was used for the placement of two 5 mm trocars and one 10 mm flexible videoscope. Conventional laparoscopic dissector, grasper, Ligasure, Harmonic Ace and hemoclips were the main tools during surgical procedure. We prefer Single Incision Laparoscopic Surgery Foam Port (Covidien) as the single umbilical device for introduction into the abdominal cavity. First, we performed cholecystectomy, then the gallbladder was put aside over the liver and after that we peformed splenectomy. To remove the detached spleen and gallbladder, a nylon extraction bag is introduced through one of the port sites. The spleen is than morcellated in the bag with forceps and removed in fragments. After that we removed them and the umbilical fascial incision was closed. Splenectomy is the only effective therapy for this disorder and often it is performed in combination with cholecystectomy. Conventional surgery requires a wide upper abdominal incision for correct exposure of the gallbladder and spleen. Our experience shows that SILS splenectomy and cholecystectomy is feasible even in young children and

Treatment of stress fracture of the olecranon in throwing athletes with internal fixation through a small incision

PubMed Central

2012-01-01

The present study is a report of retrospective case series of stress fracture of the olecranon. Six patients presented posterior elbow pain in throwing in baseball and softball, but fracture was not diagnosed in radiographs. We detected stress fracture of the olecranon using computed tomographic (CT) scan and treated the patient with internal fixation with a headless cannulated double threaded screw through a small skin incision. All patients returned to competitive level without elbow complaints after the operation. When throwing athletes present with unusual posterior elbow pain and no significant findings on radiographs, a CT scan examination should be performed. We recommend surgical treatment of internal fixation with a screw through a small skin incision, as a good option for stress fracture of the olecranon in order to allow early return to sports activity in competitive athletes.

Introduction The resection of petroclival meningiomas presents great neurosurgical challenges. Although multiple surgical approaches have been developed, the retrosigmoid route tends to be used to address tumors that are predominantly located in the posterior fossa. Our modification of the lateral suboccipital retrosigmoid approach with the placement of a tentorial incision yields good visualization of the supratentorial part of the tumor around the midbrain. Methods We treated four patients, one with primary and three with recurrent petroclival meningioma, by our modified approach. After lateral suboccipital craniotomy, the infratentorial part of the tumor was removed after detaching it from the tentorial surface. The cerebellar tentorium was then carefully incised from the supracerebellar angle, taking care not to damage the superior cerebellar artery and trochlear nerve. Results The operative field surrounding the midbrain was widened by this procedure, and safe dissection of the tumor from the brainstem and other neurovascular structures was performed with direct observation of the interface. Conclusions Our approach is a useful modification of the retrosigmoid approach to petroclival meningiomas. It facilitates the safe resection of the supratentorial part of the tumor in the ambient cistern behind the tentorium.

Tubularized incised plate urethroplasty for hypospadias reoperation: a review and meta-analysis.

Tubularized Incised Plate (TIP) urethroplasty is a technique for urethral reconstruction of hypospadias although there are some controversies for its use in recurrent cases. The aim of this study was to review the results of TIP technique in various studies and the usage of different flaps for covering the repair site. Extensive Search was performed for articles published between 1994 and 2013 in common electronic databases. The overall TIP complication rates were estimated by a fixed effects model meta-analysis. 17 articles of hypospadia repair using the TIP method were reviewed. All studies performed surgery and repair on the basis of the Snodgrass's method; however, some introduced modifications to the method. The prevalence of complications in repeated TIP surgery was 11.1 to 33.3% and the most prevalent complication in different studies was fistula. Based on the meta-analysis, the overall estimation of complications was 21.8% (95% CI: 18.3 to 25.5). Most studies performed the incision of the urethral plate to create a supportive coverage upon neourethra, and confirmed its success. We recommend further investigation on using different flaps in well-designed randomized controlled trials to choose the best surgical method for repairing recurrent hypospadias.

A Prospective randomized controlled study was conducted to compare outcome of Small Incision Cataract Surgery (SICS) using microscope or loupe magnification. Two hundred fifty one patient with mature cataract were randomly allocated to SICS-Fishhook Technique with either microscope (127 eyes) or loupe (124 eyes) magnification. Intra- and postoperative complications and immediate visual outcome were analyzed. Nearly two third (microscope 65% and magnifying loupe 62.9%) of all patients had good visual outcome on first postoperative day. Poor outcome (<6/60) was recorded in 8% (microscope group) and 7% (magnifying loupe group). Mean visual acuity with Snellen was 0.39 (SD 0.2) in microscope group and 0.38 (SD 0.2) in magnifying loupe group. Intra operative complications were comparable in both groups. Mean surgery time with loupe magnification was significantly shorter. Comparatively equivalent good surgical outcome was achieved with loupe as well as with microscope magnification. However performing SICS with loupe magnification is significantly faster. Small incision cataract surgery with loupe magnification is safe and effective procedure for cataract surgery so it can play a role in reducing cataract blindness in developing countries of the world.

Vault haematoma is one of the most common complication of vaginal hysterectomy. The aim of this work was to analyse the effects of a modification of incision and closure technique of the vaginal vault on the incidence of vault haematoma after vaginal hysterectomy. The study group consisted of 333 women of whom 49 (group A) underwent vaginal hysterectomy traditional technique of incision and closure of the vaginal vault, an 284 (group B) modified technique. Following parameters were evaluated: number of vault haematomas, blood loss, postoperative fever, required antibiotics, length of hospital stay. The risk of vault haematoma was significantly lower in the group B (1,06% vs 12,4%). Loss of blood was higher in group A (310 ml vs 206 ml). Incidence of postoperative fever was in 12,2% patients from group A, and 1,4% from group B. The length of hospitalization was lower for women in group B (4,3 days compared with 7,3 days). The modification of incision and closure technique of the vaginal vault during vaginal hysterectomy is recommended to minimise intra- and postoperative complications.

The initiation timing of rehabilitation in children with obstetric brachial plexus palsy is controversial. The aim of the present study is to evaluate the effectiveness of rehabilitation timing to the functional outcomes of patients with obstetric upper trunk brachial plexus palsy. Twenty-nine patients, who did not previously received any rehabilitation programme but attended our outpatient clinic, were included for the study. The electrophysiological findings, obstetric characteristics, and demographic features of the patients were recorded. The range of motion (ROM) of shoulders, elbows, and wrists and the strength of the muscles associated with these joints were evaluated. Modified Mallet Scale (MMS) was used for functional evaluation. A 4-week rehabilitation programme was performed twice at 2-month intervals. Patients were divided into three groups according to their ages as follows: 1-3 years old (group 1), 3-5 years old (group 2), and 5-7 years old (group 3). The ROMs, muscle strengths, and MMS scores of the patients were all evaluated. Two out of 29 patients were female (6.9%) and 27 were male (93.1%). All 29 patients had right upper extremity palsy (100%). The MMS scores, ROMs, and muscle strength of the upper extremities had improved in all the groups following the standardized rehabilitation programme. A rehabilitation programme is the best choice of treatment before surgical procedures in patients with mild to moderate obstetric upper trunk brachial plexus palsy regardless of age and the initiation time.

A facial sebaceous cyst is a common benign epithelial tumor and surgical excision is frequently performed but may cause obvious scarring and may be esthetically troubling. This study evaluated the clinical outcomes of the patients with facial sebaceous cyst enucleated by creating minimal elliptical incisions through a keratin-filled orifice. Eleven patients with facial sebaceous cyst enucleated by creating minimal elliptical incisions through a keratin-filled orifice. We treated nine male and two female patients aged 25-52 years. The mean cyst size was 1.85 × 1.56 cm. All cysts were successfully enucleated. The mean wound length was 0.93 cm. The mean operative time was 15.2 min. The mean follow-up duration was 41.5 months. No recurrence was noted, and all patients were very satisfied with their esthetic outcomes. All cysts were successfully enucleated. The mean elliptical wound length was 0.93 cm (range, 0.8-1.1 cm). The mean operative time was 15.2 min. We found no evidence of wound infection, or nerve or vascular injury. Enucleation of facial sebaceous cyst via a minimal elliptical incision through the keratin-filled orifice was associated with high-level patient satisfaction, and the method is safe and useful for treating facial epidermoid cysts. © 2016 Wiley Periodicals, Inc.

Cannabidiol Is a Potential Therapeutic for the Affective-Motivational Dimension of Incision Pain in Rats

Background: Pain involves different brain regions and is critically determined by emotional processing. Among other areas, the rostral anterior cingulate cortex (rACC) is implicated in the processing of affective pain. Drugs that interfere with the endocannabinoid system are alternatives for the management of clinical pain. Cannabidiol (CBD), a phytocannabinoid found in Cannabis sativa, has been utilized in preclinical and clinical studies for the treatment of pain. Herein, we evaluate the effects of CBD, injected either systemically or locally into the rACC, on mechanical allodynia in a postoperative pain model and on the negative reinforcement produced by relief of spontaneous incision pain. Additionally, we explored whether CBD underlies the reward of pain relief after systemic or rACC injection. Methods and Results: Male Wistar rats were submitted to a model of incision pain. All rats had mechanical allodynia, which was less intense after intraperitoneal CBD (3 and 10 mg/kg). Conditioned place preference (CPP) paradigm was used to assess negative reinforcement. Intraperitoneal CBD (1 and 3 mg/kg) inverted the CPP produced by peripheral nerve block even at doses that do not change mechanical allodynia. CBD (10 to 40 nmol/0.25 μL) injected into the rACC reduced mechanical allodynia in a dose-dependent manner. CBD (5 nmol/0.25 μL) did not change mechanical allodynia, but reduced peripheral nerve block-induced CPP, and the higher doses inverted the CPP. Additionally, CBD injected systemically or into the rACC at doses that did not change the incision pain evoked by mechanical stimulation significantly produced CPP by itself. Therefore, a non-rewarding dose of CBD in sham-incised rats becomes rewarding in incised rats, presumably because of pain relief or reduction of pain aversiveness. Conclusion: The study provides evidence that CBD influences different dimensions of the response of rats to a surgical incision, and the results establish the rACC as a brain area

Quantitative Testing of Bedrock Incision Models, Clearwater River, WA

The topographic evolution of many active orogens is dominated by the process of bedrock channel incision. Several incision models based around the detachment limited shear-stress model (or stream power model) which employs an area (A) and slope (S) power law (E = K Sn Am) have been proposed to explain this process. They require quantitative assessment. We evaluate the proposed incision models by comparing their predictions with observations obtained from a river in a tectonically active mountain range: the Clearwater River in northwestern Washington State. Previous work on river terraces along the Clearwater have provided long-term incision rates for the river, and in conjunction with previous fission track studies it has also been determined that there is a long-term balance between river incision and rock uplift. This steady-state incision rate data allows us, through the use of inversion methods and statistical tests, to determine the applicability of the different incision models for the Clearwater. None of the models successfully explain the observations. This conclusion particularly applies to the commonly used detachment limited shear-stress model (or stream power model), which has a physically implausible best fit solution and systematic residuals for all the predicted combinations of m and n.

Cemento-ossifying Fibroma (COF) is an osteogenic benign neoplasm affecting the jaws and other craniofacial bones. It commonly presents as a progressively slow growing pathology, which can sometimes attain an enormous size, causing facial deformity. A case of a huge cemento-ossifying fibroma, appearing as a mandibular dumbell tumour in a male patient is documented, which caused massive bone destruction and deformity. It was surgically removed by performing en bloc resection of mandible avoiding the splitting of lower lip incision technique, thereby maintaining his normal facial appearance.

Modified Lengthening Temporalis Myoplasty Involving an Extended Lazy-S Incision to Avoid Facial Scar Formation.

Oji, Tomito; Hayashi, Akiteru; Ogino, Akihiro; Onishi, Kiyoshi

2018-05-01

Lengthening temporalis myoplasty is a faster and less invasive alternative to free muscle transfer for smile reconstruction. However, it requires a nasolabial fold incision, which leaves a midfacial scar. Based on esthetic considerations, a modified approach, involving an extended lazy-S (parotidectomy) incision instead of a nasolabial fold incision, was developed. A cadaveric study involving 10 hemifaces was conducted. From February 2013 to March 2016, the modified lengthening temporalis myoplasty procedure was employed in 10 patients. The results were graded from 1 (poor) to 5 (excellent) according to the Terzis grading system. The excursion of the oral commissure was also measured. The extended lazy-S incision provides easy and safe access to the coronoid process and good visibility. The patients' mean age was 56.5 years, and the mean duration of the postoperative follow-up period was 22.2 months. The patients' underlying conditions included acoustic neuroma (n = 2), Bell palsy (n = 3), congenital conditions (n = 2), brain infarction (n = 1), Ramsay Hunt syndrome (n = 1), and malignant parotid lymphoma (n = 1). One patient suffered a surgical site infection, which was successfully treated with irrigation. All the patients achieved improvements in smile symmetry: 2, 5, and 3 patients obtained excellent, good, and moderate results, respectively. The excursion of the oral commissure ranged from 5 to 10 mm. The modified lengthening temporalis myoplasty procedure provides satisfactory functional outcomes without causing significant complications. It does not leave a facial scar and is a preferable option, especially for young and female patients, and patients who have undergone ablative surgery involving the parotid region.

Asymmetric Corneal Flattening Effect After Small Incision Cataract Surgery.

2016-08-01

To determine whether the flattening effect of corneal incisions differs between the right and left eye. A retrospective study of preoperative and postoperative corneal astigmatism was performed for patients who had bilateral cataract surgery by a right-handed surgeon. The change in corneal astigmatism was attributed to the 2.2-mm phacoemulsification incision, and the incisional flattening effect was calculated. The incisions were grouped by position on the eye and whether they were performed on the preoperative steep corneal meridian. A total of 1,298 eyes of 649 patients were evaluated. The flattening effect of temporal 2.2-mm incisions performed on the preoperative corneal steep meridian was different for right eyes (0.53 diopters [D]) and left eyes (0.34 D) (P = .017). The flattening effect of superior 2.2-mm incisions performed on the preoperative corneal steep meridian was equivalent in the two eyes. The flattening effect of a corneal incision may depend on whether it has been performed on the right or the left eye. [J Refract Surg. 2016;32(9):598-603.]. Copyright 2016, SLACK Incorporated.

Purpose: To study and compare the effects of the micro-incision cataract surgery (MICS-sub 1.8 mm) and miniincision coaxial phacoemulsification (2.2 mm) on the optical quality of the cornea characterized in terms of corneal aberrations. Materials and Methods: Fifty eyes underwent MICS and 50 mini-incision phacoemulsification, by the same surgeon. Both types of cataract surgery were performed using low ultrasound power and through a clear corneal incision, placed on the steepest corneal meridian ranging from 1.6 to 1.8 in MICS (Group I) and from 2.12 to 2.3 mm in mini-incision coaxial phacoemulsification (Group II). Seidel and Zernike aberration coefficients and RMS values were obtained for a 6-mm pupil preoperatively and one month after surgery. Results: The corneal astigmatism did not show statistically significant changes in either of the two groups: (MICS: –0.73 ± 0.63, –0.65 ± 0.53 D, P = 0.25), (mini-incision phacoemulsification; –1.21 ± 1.52, –1.00 ± 1.19 D, P = 0.12). The total RMS remained unchanged after MICS (1.77 ± 1.7, 1.65 ± 1.3 μm, P = 0.18) and mini-incision phacoemulsification (2.00 ± 1.87, 2.09 ± 1.8 μm, P = 0.41). Statistically significant changes were found for coma (P = 0.004) and higher-order aberrations (P < 0.001), showing MICS significantly less changes in cornea. Conclusions: Both MICS and mini-incision phacoemulsification do not degrade the optical quality of the cornea. Both surgeries do not induce a modification of the corneal astigmatism, even in the axis. It seems that 2 mm is the limit around which no optical changes are induced by cataract surgery in the human cornea. PMID:20543945

Panoramic radiography is often used to analyze the anatomical structure of the teeth, jaws, and temporomandibular joints. Cone beam computed tomography (CBCT) imaging allows multiple axial slices of the image to be obtained through these anatomical structures. The aim of this study was to assess CBCT compared with panoramic radiography to verify the presence, location, and dimensions of the mandibular incisive canal. CBCT scan images and panoramic radiographs of 89 subjects were compared for the presence of the mandibular incisive canal, its location, size, and anterior-posterior length. The distance between the incisive canal and the buccal and lingual plate of the alveolar bone, and the distance from the canal to the inferior border of the mandible and the tooth apex were also measured. A paired t-test was used to calculate any significant difference between the two imaging techniques. Eighty-three percent of the CBCT scans showed the presence of the incisive canal, as did 11% of the panoramic radiographs. The range of the incisive canal diameter, as seen in the CBCT scans, was from 0.4 × 0.4 mm to 4.6 × 3.2 mm. The mean length of the canal was 7 ± 3.8 mm. The distance from the inferior border of the mandible to the canal was 10.2 ± 2.4 mm, and the mean distance to the buccal plate was 2.4 mm. The apex-canal distance (in dentate subjects) was 5.3 mm. The presence, location, and dimensions of the mandibular incisive canal are better determined by CBCT imaging than by panoramic radiography. © 2009 Wiley Periodicals, Inc.

Surgical pulmonary embolectomy has gained increasing popularity over the past decade with multiple series reporting excellent outcomes in the treatment of submassive pulmonary embolism. However, a significant barrier to the broader adoption of surgical pulmonary embolectomy remains the large incision and long recovery after a full sternotomy. We report the safety and efficacy of using a minimally invasive approach to surgical pulmonary embolectomy. All consecutive patients undergoing surgical pulmonary embolectomy for a submassive pulmonary embolism (2015-2017) were reviewed. Patients were stratified as conventional or minimally invasive. The minimally invasive approach included a 5- to 7-cm skin incision with upper hemisternotomy to the third intercostal space. The primary outcomes were in-hospital and 90-day survival. Thirty patients (conventional = 20, minimally invasive = 10) were identified. Operative time was similar between the two groups, but cardiopulmonary bypass time was significantly longer in the minimally invasive group (58 vs 94 minutes, P = 0.04). While ventilator time and intensive care unit length of stay were similar between groups, hospital length of stay was 4.5 days shorter in the minimally invasive group, and there was a trend toward less blood product use. In-hospital and 90-day survival was 100%. Within the minimally invasive cohort, median right ventricular dysfunction at discharge was none-mild and no patient experienced postoperative renal failure, deep sternal wound infection, sepsis, or stroke. Minimally invasive surgical pulmonary embolectomy appears to be a feasible approach in the treatment of patients with a submassive pulmonary embolism. A larger, prospective analysis comparing this modality with conventional surgical pulmonary embolectomy may be warranted.

Robotic applications have achieved safe and precise thyroidectomy with notable cosmetic and functional benefits. This study was designed to document the influence of body habitus on robotic thyroidectomy in papillary thyroid carcinoma (PTC) patients. From July 2009 to February 2010, 352 patients underwent robotic thyroidectomy using a gasless, transaxillary single-incision approach at Yonsei University Health System. Body habitus was described using body mass index category (normal weight, overweight, obese), neck length, shoulder width, and shoulder width to neck length ratios. The impact of body habitus on surgical outcomes was analyzed with respect to operation time, number of retrieved central nodes, bleeding amount, and postoperative complications. Of the 352 patients, 217 underwent less than total thyroidectomy and 135 underwent total thyroidectomy. Operative variables (i.e. operation times, bleeding amounts, and numbers of retrieved central nodes) showed no significant differences between three BMI groups for less than total thyroidectomy. However, total operation and working space times were longer for obese patients during total thyroidectomy. In particular, shoulder width was positively correlated with total operation time, working space time, console time, and number of retrieved central nodes. On the other hand, postoperative complications were not significantly different in the three BMI groups and showed no significant correlation with the other indices of body habitus. Standardized robotic thyroidectomy can be performed safely and feasibly in patients with a large body habitus despite longer operation times.

Surgical Repair of Rectovaginal Fistula Using the Modified Martius Procedure: A Step-by-Step Guide.

To demonstrate the surgical repair of a rectovaginal fistula (RVF) using the modified Martius procedure. A step-by-step presentation of the procedure using video (Canadian Task Force classification III). RVF is abnormal epithelialized connections between the vagina and rectum. Causes of RVF include obstetric trauma, Crohn disease, pelvic irradiation, and postsurgical complications. Many surgical interventions have been developed, from the laparoscopic technique to muscle transposition and even rectal resection. However, the treatment of RVF is a great challenge to gynecologic surgeons because the incidence of RVF is low and there is no high evidence for the best surgical approach to this disease. When RVF is persistent or recurrent, the surrounding tissue is always scarred or damaged, so the interposition of a healthy and well-perfused tissue is an appropriate approach to fistula management. The modified Martius procedure using adipose tissue from the labia major places well-vascularized pedicle in the place of the RVF. Limited studies involving the procedure present favorable successful rates. Consent was obtained from the patient. The study was approved by the local ethics committee. The surgical repair of rectovaginal fistula by the modified Martius procedure is described as follows: The patient is placed in the high lithotomy position. A temporary transurethral urinary catheter is placed preoperatively to keep the operative site clean. The rectovaginal fistula is identified by a fistula probe. A 4-cm incision is made vertically over the left labium majus from the level of the mons pubis to the bottom of the labium to harvest pedicle. It is imperative to ensure adequate length on the flap before transection. Blood supply to the fat-muscle flap is provided superiorly by the external pudendal artery, posteriorly by the internal posterior and laterally by the obturator artery. The fat-muscle flap is dissected in a lateral-to-medial direction and divided in the

Nowadays surgical intervention is an essential part of the treatment of idiopathic gynecomastia. Choosing the right method is crucial and is based on the current status in the clinical and histological evaluation. Before finalizing the process of choosing a specific method a prior interdisciplinary evaluation of the patient is necessary to ascertain clear indications for a surgical intervention. Liposuction is one of the methods which have become popular in recent years. The advantages are the possible combination with traditional techniques, such as subcutaneous mastectomy or periareolar mastopexy. The main indication is for gynecomastia stage IIa/b and is justifiable due to the reduction in surgical complications and scarring. Furthermore this technique provides an excellent aesthetical outcome for the patient. A total of 162 patients suffering from gynecomastia stages I-III (according to Simon) were surgically treated between 2000 and 2010 and these cases were retrospectively evaluated. The results showed a decline in the use of a T-shaped incision in combination with subcutaneous mastectomy with periareolar tightening compared to an increase in the use of subcutaneous mastectomy in combination with liposuction. The excised tissue should always be sent for histological examination to make sure no malignant cells were present.

Inguinal hernia remains the most commonly encountered surgical problem. Various methods of repair have been described, and the most suitable one debated. Single port access (SPA) surgery is a rapidly evolving field, and has the advantage of affording 'scarless' surgery. Single incision laparoscopic surgery (SILS) for inguinal hernia repair is seen to be feasible in both total extraperitoneal (TEP) and transabdominal pre-peritoneal (TAPP) approaches. Data and peri-operative information on both of these however are limited. We aimed to review the clinical experience, feasibility and short term complications related to laparoscopic inguinal hernia repair via single port access. A literature search was performed using Google Scholar, Springerlink Library, Highwire Press, Surgical Endoscopy Journal, World Journal of Surgery and Medscape. The following search terms were used: laparoscopic hernia repair, TAPP, TEP, single incision laparoscopic surgery (SILS). Fourteen articles in English language related to SILS inguinal hernia repair were identified. Nine articles were related to TEP repair and the remaining 5 to TAPP. A total of 340 patients were reported within these studies: 294 patients having a TEP repair and 46 a TAPP. Only two cases of recurrence were reported. Various ports have been utilized, including the SILS port, Tri-Port and a custom- made port using conventional laparoscopic instruments. The duration of surgery was 40-100 minutes and the average length of hospital stay was one day. Early outcomes of this novel technique show it to be feasible, safe and with potentially better cosmetic outcome.

The American Academy of Pediatrics recommends operating on hypospadias between the ages of 6-12 months. Since most births in developed countries are conducted in a hospital, parents are likely to be well informed and counseled about the hypospadias. However, significant numbers of births in developing countries are still conducted at home, with illiteracy, poverty and ignorance often leading to late presentation at the hospital. Reported hypospadias-repair complication rates are higher in adults compared with those having surgery in childhood. The present study's objective was to evaluate the factors affecting surgical outcome in hypospadias patients undergoing tubularized and tubularized incised plate urethroplasty (TIPU) in adulthood compared with childhood. A prospective study of 60 adult patients >16 years, and 60 pediatric patients <5 years who underwent TIPU for primary hypospadias between May 2008 and May 2012. Patients were operated on by a single surgeon, under similar circumstances, and were pre-operatively examined to assess meatal location, chordee, and torsion; they were also examined intra-operatively for quality of spongiosum and urethral plate width. The outcomes were assessed by patient/parents for satisfaction regarding cosmesis, urinary stream and complications. The age of the patients varied from 16 to 27 years, with a mean of 20.8 years in adults, and 6 months to 5 years, with a mean of 2.1 years, in children. The type of hypospadias, degree of curvature, quality of spongiosum and urethral plate width were comparable in both groups, but complication rates were higher in adults (16.7%) than in the pediatric (6.7%) group (Figure 1A-D). Meatal stenosis responded well to dilatation, but fistulae required revision surgery and had a cure rate of 100%. The median follow-up was 37 months in adults, and 39 months in children. The higher complication rates in adults may be due to more frequent erections; increased susceptibility to infection along with

The Obstetric Anaesthetists' Association and Difficult Airway Society have developed the first national obstetric guidelines for the safe management of difficult and failed tracheal intubation during general anaesthesia. They comprise four algorithms and two tables. A master algorithm provides an overview. Algorithm 1 gives a framework on how to optimise a safe general anaesthetic technique in the obstetric patient, and emphasises: planning and multidisciplinary communication; how to prevent the rapid oxygen desaturation seen in pregnant women by advocating nasal oxygenation and mask ventilation immediately after induction; limiting intubation attempts to two; and consideration of early release of cricoid pressure if difficulties are encountered. Algorithm 2 summarises the management after declaring failed tracheal intubation with clear decision points, and encourages early insertion of a (preferably second-generation) supraglottic airway device if appropriate. Algorithm 3 covers the management of the ‘can't intubate, can't oxygenate’ situation and emergency front-of-neck airway access, including the necessity for timely perimortem caesarean section if maternal oxygenation cannot be achieved. Table 1 gives a structure for assessing the individual factors relevant in the decision to awaken or proceed should intubation fail, which include: urgency related to maternal or fetal factors; seniority of the anaesthetist; obesity of the patient; surgical complexity; aspiration risk; potential difficulty with provision of alternative anaesthesia; and post-induction airway device and airway patency. This decision should be considered by the team in advance of performing a general anaesthetic to make a provisional plan should failed intubation occur. The table is also intended to be used as a teaching tool to facilitate discussion and learning regarding the complex nature of decision-making when faced with a failed intubation. Table 2 gives practical considerations of how

In the first step of rhinoplasty, the surgical approach will expose through different types of incisions and dissection planes the osteocartilaginous framework of the nasal pyramid prior to performing actions to reduce or increase the latter. This exposure can be performed by a closed approach or by an external approach--the choice depends on the type of nose and the habits of the surgeon. Far from being opposites, closed and external approaches are complementary and should be known and mastered by surgeons performing rhinoplasty. Copyright © 2014 Elsevier Masson SAS.

ABSTRACT Objectives The purpose of the present study was to review the literature of how to identify the mental foramen, mandibular incisive canal and associated neurovascular bundles during implant surgery and how to detect and avoid the damage of these vital structures during implant therapy. Material and Methods Literature was selected through a search of PubMed, Embase and Cochrane electronic databases. The keywords used for search were mandibular incisive canal, mental foramen, mental nerve, anterior mental loop. The search was restricted to English language articles, published from 1979 to November 2009. Additionally, a manual search in the major anatomy, dental implant, and periodontal journals and books was performed. Results In total, 47 literature sources were obtained and reviewed. The morphology and variations of the mandibular incisive canal, mental foramen and associated neurovascular bundles were presented as two entities. It suggested that clinicians should carefully assess these vital structures to avoid nerve/artery damage. Conclusions The mandibular incisive canal, mental foramen and associated neurovascular bundles exist in different locations and possess many variations. Individual, gender, age, race, assessing technique used and degree of edentulous alveolar bone atrophy largely influence these variations. It suggests that the clinicians should carefully identify these anatomical landmarks, by analyzing all influencing factors, prior to their implant surgical operation. PMID:24421959

There is a significant burden of disease in low-income countries that can benefit from surgical intervention. The goal of this survey was to evaluate the current ability of the Liberian health care system to provide safe surgical care and to identify unmet needs in regard to trained personnel, equipment, infrastructure, and outcomes measurement. A comprehensive survey tool was developed to assess physical infrastructure of operative facilities, education and training for surgical and anesthesia providers, equipment and medications, and the capacity of the surgical system to collect and evaluate surgical outcomes at district-level hospitals in Africa. This tool was implemented in a sampling of 11 county hospitals in Liberia (January 2011). Data were obtained from the Ministry of Health and by direct government-affiliated hospital site visits. The total catchment area of the 11 hospitals surveyed was 2,313,429--equivalent to roughly 67 % of the population of Liberia (3,476,608). There were 13 major operating rooms and 34 (1.5 per 100,000 population) physicians delivering surgical, obstetric, or anesthesia care including 2 (0.1 per 100,000 population) who had completed formal postgraduate training programs in these specialty areas. The total number of surgical cases for 2010 was 7,654, with approximately 43 % of them being elective procedures. Among the facilities that tracked outcomes in 2010, a total of 11 intraoperative deaths (145 per 100,000 operative cases) were recorded for 2009. The 30-day postoperative mortality at hospitals providing data was 44 (1,359 per 100,000 operative cases). Metrics were also used to evaluate surgical output, safety of anesthesia, and the burden of obstetric disease. A significant volume of surgical care is being delivered at county hospitals throughout Liberia. The density and quality of appropriately trained personnel and infrastructure remain critically low. There is strong evidence for continued development of emergency and

To prospectively assess the efficacy of bimanual phacoemulsification and implantation of Thinoptx, an injectable intraocular lens (IOL), inserted through 1.70 mm clear corneal incision. Department of Ophthalmology, Southend Hospital NHS Trust, UK. A total of 50 eyes of 49 randomly selected patients with cataracts had microincision clear corneal bimanual phacoemulsification (MICS) with implantation of Thinoptx IOL in the capsular bag. All patients underwent full preoperative assessment. Postoperative assessment was carried out at 3 and 6 weeks and at 15 months. In all 50 cases the IOL was inserted through 1.70 mm clear corneal incision. The mean best-corrected visual acuity was 0.02 (6/6-1) at 6 weeks and was 0.17 (6/10) at the final follow-up. The mean final surgically induced astigmatism at 6 weeks was 0.0106. Coloured haloes around artificial lights were perceived by 69.23% of patients at 6 weeks and by 61.29% at the final follow-up. One patient underwent IOL exchange for this. Posterior capsular opacification was noticed in 31.26% at 6 weeks and in 64.51% at 15 months. Anterior capsular opacification was noticed in 5.26% at 6 weeks and in 16.12% at 15 months. In one patient the IOL had to be exchanged because of tilt and displacement of the IOL due to anterior capsular phimosis. We conclude Thinoptx can be safely inserted through 1.70 mm incision used for bimanual phacoemulsification. Distance and near visual acuity achieved with this IOL is satisfactory. There is no significant change in keratometric astigmatism following this procedure. However, posterior capsular opacification rate was significantly higher with this IOL. Haloes around light sources were significant.

To present the results of Maylard incisionfor gynecologic surgery in Thammasat University Hospital during the past four years. A retrospective study of gynecologic surgery performed via the Maylard muscle cutting incision compare to Pfannenstiel muscle splitting and midline incision. Data came from subjects who underwent gynecologic surgey at Thammasat University Hospital, Pathumthani, Thailand friom January 2010 to December 2013. In the period of 4 years, there were 283 cases of elective surgery that performed via Maylard, Pfannenstiel and midline incision by the single experience gynecologic surgeon team. One hundred and six cases were performed via Maylard incision technique. The remaining 59 and 118 cases were performed via Pfannenstiel and midline incision technique, respectively. Two-thirds and one-thirds of cases underwent hysterectomy and conservative surgery, respectively. Benign conditions were the major indicationfor surgery at the percentage of 83.4. Operative results were not significantly different from well-known midline and Pfannenstiel incision in terms of blood loss, time to first meal and postoperative pain. Operative time in Maylard incision was longer than in Pfannenstiel incision. Length of stay in Maylard incision was longer than Pfannenstiel but shorter than midline incision. Overall complications (eoperation, bowel injuries, urinary bladder injuries and blood transfusion rate) were not significantly different. Maylard incision provides similar operative results with midline and Pfannenstiel technique. Even though it takes more time for abdominal entry but it gives more operative exposure than Pfannenstiel incision. In the woman with previous low transverse scar and gynaecologic surgery is needed, Maylard incision could be an optional technique that provides cosmetic and successfud results. Hand on training for Maylard incision from their mentors should be encouraged to more practice.

The present retrospective cohort study included patients presenting for the treatment of symptomatic uterine fibroids at the Gynecology Fibroid Clinic at Mayo Clinic, Rochester, USA, between April 1, 2013 and April 1, 2014. Magnetic resonance imaging of fibroid uteri was performed and the images were independently reviewed by two academic gynecologists and two radiologists specializing in fibroid care. Fibroid classifications assigned by each physician were compared and the significance of the variations was graded by whether they would affect surgical planning. There were 42 fibroids from 23 patients; only 6 (14%) fibroids had unanimous classification agreement. The majority (36 [86%]) had at least two unique answers and 4 (10%) fibroids had four unique classifications. Variations in classification were not associated with physician specialty. More than one-third of the classification discrepancies would have impacted surgical planning. FIGO fibroid classification was not consistent among four fibroid specialists. The variation was clinically significant for 36% of the fibroids. Additional validation of the FIGO fibroid classification system is needed. © 2017 International Federation of Gynecology and Obstetrics.

Introduction Single Incision Laparoscopic Surgery (SILS) is one of the most recent developments which have been made in the field of minimal assesses surgery. It has potential advantages of less postoperative pain and better cosmesis, but at the same time, this procedure is time consuming and it increases the cost of surgery. Aim In this study, we evaluated the feasibility, safety and potential advantages of single incision laparoscopic assisted appendectomy. Materials and Methods Single incision laparoscopic assisted appendectomy was done in 82 patients who were diagnosed with acute or chronic appendicitis. A single 10mm incision made over right lower quadrant was used for placing two 5mm trocars and appendisectomy was done as in open surgery, after delivering out the appendix from the incision. Results Mean operative time was 32.56 ± 15.5 minutes. Mean post-operative pain scores as per visual analogue scalewere 6.5, 4.2 and 1.2 on 12 hours day 1 and day 2 after surgery respectively. Mean length of hospital stay was 1.4 ± 1.2 days. Conclusion Single incision laparoscopic appendectomy is safe and feasible. PMID:27437295

Does UV disinfection compromise sutures? An evaluation of tissue response and suture retention in salmon surgically implanted with transmitters

Walker, Ricardo W.; Brown, Richard S.; Deters, Katherine A.

Ultraviolet radiation (UVR) can be used as a tool to disinfect surgery tools used for implanting transmitters into fish. However, the use of UVR could possibly degrade monofilament suture material used to close surgical incisions. This research examined the effect of UVR on monofilament sutures to determine if they were compromised and negatively influenced tag and suture retention, incision openness, or tissue reaction. Eighty juvenile Chinook salmon Oncorhynchus tshawytscha were surgically implanted with an acoustic transmitter and a passive integrated transponder. The incision was closed with a single stitch of either a suture exposed to 20 doses of UV radiationmore » (5 minute duration per dose) or a new, sterile suture. Fish were then held for 28 d and examined under a microscope at day 7, 14, 21 and 28 for incision openness, ulceration, redness, and the presence of water mold. There was no significant difference between treatments for incision openness, redness, ulceration or the presence of water mold on any examination day. On day 28 post-surgery, there were no lost sutures; however, 2 fish lost their transmitters (one from each treatment). The results of this study do not show any differences in negative influences such as tissue response, suture retention or tag retention between a new sterile suture and a suture disinfected with UVR.« less

Obstetric hysterectomy is indicated when patient's life is at risk, and it is a procedure that requires a highly experienced and skilled medical team to solve any complication. To identify incidence, indications, and complications of obstetric hysterectomy within a high-risk population. Transversal, retrospective study from July 1st 2004 to June 30 2006 at Unidad Medica de Alta Especialidad, Hospital de Ginecoobstetricia, Centro Medico Nacional de Occidente, IMSS. There were reviewed 103 patient' files with obstetric hysterectomy. Incidence was calculated, and clinical and socio-demographic characteristics, indications, and complications of obstetric hysterectomy identified and expressed in frequency, percentages, and central tendency measurements. Incidence of obstetric hysterectomy was 8 cases within every 1,000 obstetric consultation. Age average was 31.1 +/- 5.1 years. 72.8% had cesarean surgery history. Main indication was placenta previa associated with placenta accreta (33%), followed by uterine hypotony (22.3%). Complications were hypovolemic shock (56.3%), and vesical injuries (5.8%). There were no maternal deaths. Cesarean history induces higher obstetric hysterectomy incidence in women with high-risk pregnancy, due to its relation to placentation disorders, as placenta previa that increases hemorrhage possibility, and thus, maternal morbidity and mortality.

The purpose of this work was to study the incidence of clear corneal wound leakage at the conclusion of standard co-axial phacoemulsification in a prospective observational series of 100 consecutive cataract cases in a single surgeon's institutional practice. At the conclusion of standard co-axial phacoemulsification using a 2.75 mm temporal single plane clear corneal incision with a 1 mm clear corneal side-port incision, the wounds were hydrated and checked for water-tightness. Povidone iodine 5% (P-I) was then evenly dripped over the cornea and the wounds were inspected visually. Any leakage of aqueous observed was recorded. The amount of leakage was graded as small or large from each wound. Leaky wounds were further hydrated and retested with P-I until sealed. Wound integrity was reassessed on the first postoperative day by use of fluorescein. Of the 100 cases, wound leakage was observed for 31 eyes (31%)-ten main incisions, nineteen side-port incisions, and both incisions in two cases. Wound leakage was easily detected as a ribbon of clear fluid streaming from the incision amid a pool of brown solution. Povidone iodine was not observed within the tract in any incision. All wound leakage was small except for one from the main incision and two from the side-port incision. None of the eyes developed wound leakage the day after surgery and none developed endophthalmitis. In conclusion, leakage from clear corneal incisions at the conclusion of phacoemulsification occurs in almost a third of cases, predominantly from the side incision. It is easily detected by use of the P-I test.

Background: In this era of minimally invasive treatment, it is important to make operative scars as inconspicuous as possible, and there is a great deal of room for improvement in daily practice. Zigzag incision with coronal incision has been described mainly in the field of plastic surgery, and its applicability for skin incision in general neurosurgery has not been reported. Methods: Zigzag incision with 1.5-layer method was applied to 14 patients with unruptured cerebral aneurysm between April 2011 and August 2012. A questionnaire survey was administered among patients with unruptured aneurysm using SF-36v2 since April 2010. The results were compared between patients with zigzag incision and a previous cohort with traditional incision. Results: There were no cases of complications associated with the operative wound. In the questionnaire survey, all parameters tended to be better in the patients with zigzag incision, and role social component score (RCS) was significantly higher in the zigzag group than in the traditional incision group (P =0.0436). Conclusion: Zigzag incision using the 1.5-layer method with frontotemporal craniotomy seems to represent an improvement over the conventional curvilinear incision with regard to cosmetic outcome and RCS.

Okaro, J M; Anya, S E

2004-01-01

Caesarian section is the most common major surgical procedure among women of reproductive age. It is thought to be safer for the baby than the mother. However, the baby is at risk of laceration injury. Retrospective review of clinical records of women who were delivered by caesarian section during a seven-year period from January 1, 1991 to December 31, 1997. Fetal laceration injury was documented in 0.55% of live caesarian section births. Accidental incision of the fetus was associated with emergency caesarian section, ruptured membranes and relative inexperience of the operating surgeon. Documentation of injury was poor and there was no evidence that parents were counselled. Laceration of the fetus is an occasional complication of caesarian section. Proper documentation and counselling of parents are required especially as there are potential medicolegal implications. Careful attention to the technique of uterine entry at caesarian section should reduce the risk of injury to the fetus.

The aim of this study was to review and evaluate the selection and dose of anesthetic agents and the interval from the block procedure to skin incision for supraclavicular brachial plexus block in upper extremity surgery. We reviewed our cases that underwent upper extremity surgery using only ultrasound-guided supraclavicular brachial plexus block in our hospital between 2011 and 2016. Adverse events during surgery were evaluated. Receiver operating characteristic (ROC) curves were constructed to investigate the relationship between the time from the end of the block procedure to skin incision and the use of local anesthesia on the surgical site. There were 255 patients who were divided into three groups according to the anesthetic agents used: group 1, 1% lidocaine (L) 10 ml + 0.75% ropivacaine (R) 20 ml (n = 62); group 2, L 20 ml + R 10 ml (n = 93); and group 3, L 10 ml + R 15 ml (n = 100). The rate of use of local anesthesia on the surgical site was significantly higher in group 3 than in the other two groups. There were no significant differences in the other evaluated items among the three groups. ROC curve analysis indicated that ≥24 min from the end of the block procedure to skin incision might reduce the use of local anesthesia. The total volume of anesthetic agents had an important influence on the rate of the addition of local anesthesia for surgical pain; however, the combined dose of agents did not influence the evaluation items. For effective analgesia, ≥24 min should elapse from the end of the block procedure to skin incision. Copyright © 2017. Published by Elsevier B.V.

Although many outcomes have been compared between a midline and chevron incision, this is the first study to examine rectus abdominis atrophy after these two types of incisions. Patients undergoing open pancreaticobiliary surgery between 2007 and 2011 at our single institution were included in this study. Rectus abdominis muscle thickness was measured on both preoperative and follow-up computed tomography (CT) scans to calculate percent atrophy of the muscle after surgery. At average follow-up of 24.5 and 19.0 months, respectively, rectus abdominis atrophy was 18.9% greater in the chevron (n = 30) than in the midline (n = 180) group (21.8 vs. 2.9%, p < 0.0001). Half the patients with a chevron incision had >20% atrophy at follow-up compared with 10% with a midline incision [odds ratio (OR) 9.0, p < 0.0001]. No significant difference was observed in incisional hernia rates or wound infections between groups. In this study, chevron incisions resulted in seven times more atrophy of the rectus abdominis compared with midline incisions. The long-term effects of transecting the rectus abdominis and disrupting its innervation creates challenging abdominal wall pathology. Atrophy of the abdominal wall can not be readily fixed with an operation, and this significant side effect of a transverse incision should be factored into the surgeon's decision-making process when choosing a transverse over a midline incision.

Obstetric fistula is a debilitating childbirth injury that has been associated with high rates of psychological distress. Global efforts have helped to link women to surgical repair, but thus far no evidence-based interventions exist to address the psychological needs of these women during the hospital stay. In this paper, we describe the development of a psychological intervention for women in Tanzania who are receiving surgical care for an obstetric fistula. The intervention was developed based on theories of cognitive behavioral therapy and coping models. Content and delivery were informed by qualitative data collection with a range of stakeholders including women with fistula, and input from a study advisory board. The resulting intervention was six individual sessions, delivered by a trained community health nurse. The session topics were: 1) recounting the fistula story; 2) creating a new story about the fistula; 3) loss, grief and shame; 4) specific strategies for coping; 5) social relationships; and 6) planning for the future. A trial run of the intervention revealed that the intervention could be delivered with fidelity and was acceptable to patients. A future randomized control trial will evaluate the efficacy of this intervention to address the mental health symptoms of this population. PMID:25710896

From the beginning of the world assisting during childbirth was and is the women's domain. On the evolution this profession composed of many famous midwifes. Into this group unquestionably we can count Justine Siegemundin (1636-1705), midwife-self-taught person. Her activity contributed to rise the obstetrics knowledge in XVII century. Justine Siegemundin, the midwife of the Brandenburg court, published in 1690 a book describing a surgical trick still bears her name today. It is called the "double hold"--"Gedoppelter Handgriff", or "Siegemundin-Handgriff". This book counts as on the most important milestones of obstetrics history.

Despite over 40 years of research there has been little progress in the prevention of obstetric fistula and women continue to suffer in unacceptable numbers. Gender power imbalance has consistently been shown to have serious implications for women's reproductive health and is known to persist in regions where obstetric fistula occurs. Yet, there is limited research about the role gender power imbalance plays in childbirth practices that put women at risk for obstetric fistula. This information is vital for developing effective maternal health interventions in regions affected by obstetric fistula.

Surgical approaches for atrial fibrillation.

PubMed

Schouchoff, Barbara

2007-01-01

The Cox Maze procedure, a cardiac intervention that was developed by James Cox, MD, was first performed in 1988 to surgically cure atrial fibrillation. Over the years, changes in techniques of the classic maze were made, culminating in the Cox Maze III procedure, the Gold Standard. Modifications in the original procedure included simplifying the procedure to a minimally invasive approach. As a result of some of these modifications, the initial maze-like series of surgical atrial incisions has been reduced with the use of alternate energy sources that create hyperthermic lesion lines of conduction block that isolate and interrupt the abnormal impulses. The minimize, a minimally invasive thorascopic approach, can be performed off pump, thus avoiding a median sternotomy and cardiopulmonary bypass and cardioplegic arrest intraoperatively and ensuring a shorter, less painful recovery.

Basal cell nevus syndrome (aka Gorlin syndrome, Gorlin-Goltz syndrome, nevoid basal cell carcinoma syndrome, and fifth phacomatosis) is a rare but well-described autosomal dominant condition with variable penetrance. We present a female patient who has been successfully treated using local surgical excision and diligent skin surveillance for more than 4 decades, demonstrating that simple local incision is an efficacious and reasonable surgical alternative that may circumvent the specialization and expense of Mohs technique.

Anterior mandibular apical base augmentation in the surgical orthodontic treatment of mandibular retrusion.

The authors describe a surgical technique alternative to traditional pre-surgical orthodontics in order to increase the apical base in mandibular retrusion (class II, division I). This subapical osteotomy, optimizing inferior incisal axis without dental extractions and a long orthodontic treatment, associated to genioplasty permits to obtain an ideal labio-dento-mental morphology. This procedure avoids in some cases the need of a mandibular advancement and, if necessary, it reduces his entity with obvious advantages.

AIM: To evaluate the clinical and functional results after repair of distal biceps tendon tears, following the Morrey’s modified double-incision approach. METHODS: We retrospectively reviewed 47 patients with distal rupture of biceps brachii treated between 2003 and 2012 in our Orthopedic Department with muscle-splitting double-incision technique. Outcome measures included the Mayo elbow performance, the DASH questionnaire, patient’s satisfaction, elbow and forearm motion, grip strength and complications occurrence. RESULTS: At an average 18 mo follow-up (range, 7 mo-10 years) the average Mayo elbow performance and DASH score were respectively 97.2 and 4.8. The elbow flexion range was 94%, extension was -2°, supination was 93% and pronation 96% compared with the uninjured limb. The mean grip strength, expressed as percentage of respective contralateral limb, was 83%. The average patient satisfaction rating on a Likert scale (from 0 to 10) was 9.4. The following complications were observed: 3 cases of heterotopic ossification (6.4%), one (2.1%) re-rupture of the tendon at the site of reattachment and 2 cases (4.3%) of posterior interosseous nerve palsy. No complication required further surgical treatment. CONCLUSION: This technique allows an anatomic reattachment of distal biceps tendon at the radial tuberosity providing full functional recovery with low complication rate. PMID:25133147

The malpractice premium costs of obstetrics.

Norton, S A

1997-01-01

This study examined, in 1992, the variation in the level of malpractice premiums, and the incremental malpractice premium costs associated with the practice of obstetrics for family practitioners and obstetricians. On average, in 1992 obstetricians and family practitioners providing obstetric services paid malpractice premiums of roughly $44,000 and $16,000, respectively. The incremental increase in malpractice premium costs represented roughly 70% of the premium the physicians would have paid had they not provided obstetric services. These results suggest that for both family practitioners and obstetricians, there is a considerable premium penalty associated with providing obstetric services which may have implications for women's access to obstetric services. Moreover, the results make it clear that physicians practicing in different states, and different specialists within a state, may face very different malpractice premium costs.

A comparison of obsidian and surgical steel scalpel wound healing in rats.

PubMed

Disa, J J; Vossoughi, J; Goldberg, N H

1993-10-01

There are several anecdotal clinical articles claiming wound healing and scar superiority using obsidian (volcanic glass) scalpels. In order to determine if skin incisions made with obsidian were superior to those made with standard surgical steel, wound tensile strength, scar width, and histology were assessed in 40 adult male Sprague-Dawley rats. Each rat received two parallel 8-cm dorsal skin incisions, one with an obsidian scalpel and the other with a surgical steel scalpel (no. 15 blade). Data were analyzed by ANOVA. Tensile strength of the two wound types was not different at 7, 14, 21, and 42 days. Scar width, however, was significantly less in the obsidian wounds at 7, 10, and 14 days (p < 0.005). At 21 days, scar width was not different in the two groups. At 42 days, all wounds were barely detectable, thus precluding scar width analysis. A blinded histologic review suggested that obsidian wounds contained fewer inflammatory cells and less granulation tissue at 7 days.

Objective: We developed a new surgical model of penile girth enhancement in dog, with minimal damage, fewer complications, and high success rate, to enable the experimental investigation of penile implants. Methods: We obtained materials for penile girth enhancement by processing the pericardium and blood vessel wall collected from pigs. Incisions were made at the penile bulb for the implantation of the materials, and facilitate observation and data collection, based on the anatomical features of dog’s penis. We measured the girth of the flaccid penis before and after the operation, and erectile function at 1-month postoperation. In addition to evaluation of recovery from the incision and local pathological changes, ultrasonic examination was performed to monitor the long-term changes associated with implantation. Results: The mean girth of the flaccid penis significantly increased from 7.37±0.40 cm before the operation, to 8.70±0.56 cm postoperation. Dogs resumed normal mating at 1 month after the operation, without any significant change in the mating time. Ultrasonic examination clearly illustrated the implants, and helped in the measurement of the distance between the materials and the baculum. Conclusion: Chinese Rural dog is a promising animal model for penile girth enhancement surgery. The findings demonstrated that surgical implantation into penile bulb was associated with less damage, faster postoperative recovery, and higher success. For the first time, ultrasonic examination provided objective data on the surgical outcomes of penile girth enhancement. PMID:26379868

Surgical Site Infiltration for Abdominal Surgery: A Novel Neuroanatomical-based Approach

PubMed Central

Janis, Jeffrey E.; Haas, Eric M.; Ramshaw, Bruce J.; Nihira, Mikio A.; Dunkin, Brian J.

2016-01-01

Background: Provision of optimal postoperative analgesia should facilitate postoperative ambulation and rehabilitation. An optimal multimodal analgesia technique would include the use of nonopioid analgesics, including local/regional analgesic techniques such as surgical site local anesthetic infiltration. This article presents a novel approach to surgical site infiltration techniques for abdominal surgery based upon neuroanatomy. Methods: Literature searches were conducted for studies reporting the neuroanatomical sources of pain after abdominal surgery. Also, studies identified by preceding search were reviewed for relevant publications and manually retrieved. Results: Based on neuroanatomy, an optimal surgical site infiltration technique would consist of systematic, extensive, meticulous administration of local anesthetic into the peritoneum (or preperitoneum), subfascial, and subdermal tissue planes. The volume of local anesthetic would depend on the size of the incision such that 1 to 1.5 mL is injected every 1 to 2 cm of surgical incision per layer. It is best to infiltrate with a 22-gauge, 1.5-inch needle. The needle is inserted approximately 0.5 to 1 cm into the tissue plane, and local anesthetic solution is injected while slowly withdrawing the needle, which should reduce the risk of intravascular injection. Conclusions: Meticulous, systematic, and extensive surgical site local anesthetic infiltration in the various tissue planes including the peritoneal, musculofascial, and subdermal tissues, where pain foci originate, provides excellent postoperative pain relief. This approach should be combined with use of other nonopioid analgesics with opioids reserved for rescue. Further well-designed studies are necessary to assess the analgesic efficacy of the proposed infiltration technique. PMID:28293525

Single-incision laparoscopic cholecystectomy (SILC) is a promising alternative to standard multi-incision laparoscopic cholecystectomy (LC). However, generalization of SILC is still hampered by technical difficulties mainly associated with the lack of trocars used for retraction of the gallbladder. We therefore developed a modified method of SILC with the use of needle graspers (SILC-N) for optimal retraction and exposure. In addition to two trocars inserted through a single transumbilical incision, two needle ports were placed on the right subcostal and lateral abdominal wall, through which needle graspers were used for retraction of the gallbladder. Since December, 2009, 12 patients with symptomatic cholelithiasis were treated by SILC-N. SILC-N was successfully performed in all but one patient requiring a conversion to the 4-port LC with a mean operative time of 71.5 (48-107) minutes. None of the patients experienced intraoperative or postoperative complications. The transumbilical incision and pinholes for needle graspers were almost invisible on discharge. Our preliminary results suggest that SILC-N is a simple, safe and feasible technique of cholecystectomy offering similar postoperative recovery and better cosmetic outcome as compared to conventional LC.

In a retrospective study, the authors analyzed the surgical approach to the intrathoracic goiter to avoid sternotomy or thoracotomy. We selected 70 intrathoracic cases of multinodular goiter out of 988 cases of thyroidectomy and compared them with cervical goiter cases. Surgical technique, results, and postsurgical complications were assessed. The analyzed cases presented the retrosternal goiter (n = 53; 75.7%), the retrotracheal goiter (n = 9; 12.8%), and the retroesophageal goiter (n = 8; 11.4%). Complaining of chest pressure or discomfort was specific for intrathoracic cases (50%; 35 of 70). All goiters except one were removed via cervical incision. The surgeons used head reclination and isthmus dissection when removing sizable goiters. Mean weight of goiters was 180 g. The recurrent laryngeal nerve was more often temporarily damaged in intrathoracic cases in comparison with cervical cases (4.3% vs. 2.8%, P  = .04), but the difference in permanent injury was less significant ( P  = .09). The incidence of temporary hypoparathyroidism was significantly higher in intrathoracic cases ( P  = .01). In cases of multinodular goiter the goiters of various extensions can be successfully removed via the cervical incision in most of the cases even if they occupy the retrosternal, retrotracheal, or retroesophageal position. The transthoracic approaches and sternotomy might be justified in malignant cases. 4.

Zambia has a high maternal mortality ratio, 398/100,000 live births. Few pregnant women access emergency obstetric care services to handle complications at childbirth. We aimed to assess the deficit in life-saving obstetric services in the rural and urban areas of Kapiri Mposhi district. A cross-sectional survey was conducted in 2011 as part of the 'Response to Accountable priority setting for Trust in health systems' (REACT) project. Data on all childbirths that occurred in emergency obstetric care facilities in 2010 were obtained retrospectively. Sources of information included registers from maternity ward admission, delivery and operation theatre, and case records. Data included age, parity, mode of delivery, obstetric complications, and outcome of mother and the newborn. An approach using estimated major obstetric interventions expected but not done in health facilities was used to assess deficit of life-saving interventions in urban and rural areas. A total of 2114 urban and 1226 rural childbirths occurring in emergency obstetric care facilities (excluding abortions) were analysed. Facility childbirth constituted 81% of expected births in urban and 16% in rural areas. Based on the reference estimate that 1.4% of childbearing women were expected to need major obstetric intervention, unmet obstetric need was 77 of 106 women, thus 73% (95% CI 71-75%) in rural areas whereas urban areas had no deficit. Major obstetric interventions for absolute maternal indications were higher in urban 2.1% (95% CI 1.60-2.71%) than in rural areas 0.4% (95% CI 0.27-0.55%), with an urban to rural rate ratio of 5.5 (95% CI 3.55-8.76). Women in rural areas had deficient obstetric care. The likelihood of under-going a life-saving intervention was 5.5 times higher for women in urban than rural areas. Targeting rural women with life-saving services could substantially reduce this inequity and preventable deaths.

The antimicrobial and anti-inflammatory activity of honey and its ability to accelerate wound healing make it an attractive option in surgical wound care. We performed a randomized clinical trial to compare the efficacy of honey dressing with conventional dressing regarding the aesthetic outcome. Bilateral symmetric incisions in randomly selected plastic surgical patients were randomly covered postoperatively with conventional dressing and honey dressing for five days. The aesthetic outcome of the two sides was rated on a Visual Analog Scale by the surgeon and the patient and compared at month three and six after surgery. Seventy two symmetrical incisions in 52 patients were evaluated during the study. The mean width of the scar after the third and the sixth month was 3.64 +/- 0.83 mm and 3.49 +/- 0.87 mm on the side that received honey dressing and 5.43 +/- 0.05 mm and 5.30+/- 1.35 mm in the control group. Wilcoxon signed-rank test showed significant difference between honey and conventional dressing outcomes at third and sixth month (p < 0.001). The healing process of the surgical wound and its final aesthetic result could be improved by using honey dressing. © 2016 S. Karger GmbH, Freiburg.

This study explores barriers and facilitating factors women experience re-integrating into society after treatment of an obstetric fistula in rural Tanzania. A total of 71 women were interviewed in the Mwanza region of Tanzania, including a community control group. The majority of the women who received successful surgical repairs reported that, over time, they were able to resume many of the social and economic activities they engaged in prior to the development of a fistula. Familial support facilitated both accessing repair and recovery. For 60% of the women recovering from an obstetric fistula, work was the most important factor in helping them feel 'normal again'. However, physical limitations and other residual problems often hampered their ability to continue working. All of the treated women expressed interest in follow-up discussions with health care providers regarding their health and concerns about future pregnancies. Special attention is needed for women who are not completely healed and/or for those who experience other related medical or emotional problems after repair, especially if they lack a social network.

To survey infrastructure characteristics, personnel, equipment and procedures of surgical, obstetric and anaesthesia care in 17 hospitals in Ghana. The assessment was completed by WHO country offices using the World Health Organization Tool for Situational Analysis to Assess Emergency and Essential Surgical Care, which surveyed infrastructure, human resources, types of surgical interventions and equipment in each facility. Overall, hospitals were well equipped with general patient care and surgical supplies. The majority of hospitals had a basic laboratory (100%), running water (94%) and electricity (82%). More than 75% had the basic supplies needed for general patient care and basic intra-operative care, including sterilization. Almost all hospitals were able to perform major surgical procedures such as caesarean sections (88%), herniorrhaphy (100%) and appendectomy (94%), but formal training of providers was limited: a few hospitals had a fully qualified surgeon (29%) or obstetrician (36%) available. The greatest barrier to improving surgical care at district hospitals in Ghana is the shortage of adequately trained medical personnel for emergency and essential surgical procedures. Important future steps include strengthening their number and qualifications. © 2010 Blackwell Publishing Ltd.

This paper presents a case of a pregnant woman with a history of two cesarean sections. The patient was admitted to the hospital because of vaginal bleeding. The ultrasound revealed a placenta covering the internal os. The placenta was characterized by heterogeneous echogenicity with visible irregular hypoechogenic areas and blurred border between the placenta and the cervix. Rich vascularity was observed on the border of the placenta, urethra and the urinary bladder. Cystoscopy showed severe congestion around the urethra. On the back wall of the bladder a slightly increased vascularity was seen, which did not allow to confirm or exclude placental ingrowth in the urinary bladder. At 38 weeks, the patient was scheduled for an elective cesarean section. A classic perpendicular incision and leaving the placenta in the uterine cavity were proposed. After opening the abdomen, a strong vascularization in the region of lower part of the uterus and the urinary bladder was seen. Uterine incision in the fundus and the posterior wall was performed. A female fetus (weight: 2950g, Apgar: 10,10) was born. Then, the umbilical cord was ligated with non-absorbable suture and inserted back into the uterus. However, due to the presence of abundant and persistent vaginal bleeding during the next few minutes, conversion to obstetric hysterectomy was required. During relaparotomy fragments of the placenta appeared on the right side after sliding the urinary bladder. The bladder and the left ureter were damaged during surgery. The urinary bladder was sewn after removal of the uterus. Next, the urologist anastomosed end-to-end the left ureter on the pigtail catheter In the third hour of operation, cardiac arrest was caused by ventricular fibrillation. Immediate resuscitation with defibrillation allowed to restore normal function of the cardiovascular system. Total blood loss during the operation was 3000-4000 ml.

Although many aesthetic surgeons believe that beveling the angle of an incision improves the aesthetic outcome with regard to scaring, the literature remains scarce largely because few studies have been conducted. This systematic review therefore aims to identify whether using a beveled incision adds an aesthetic benefit, to determine whether there is a specific angle that yields a superior outcome, and for the first time, to present a complete discussion of this subject for practicing surgeons. A comprehensive literature search was performed using the PubMed database to search for primary articles. The main inclusion criteria were primary journal articles investigating the use of a beveled angle via a controlled study. A total of fifty-four publications were reviewed, with only four publications including 124 patients suitable for use in this systematic review. All the studies concluded that the use of a beveled angle incision improved aesthetic outcomes, with the ideal angle ranging from 10° to 45°. The use of a beveled angle incision can improve scar aesthetics and encourages the regrowth of hair follicles and shafts through the scars via multiple mechanisms. Nevertheless, the paucity of literature available to the practitioner compels further research assessing this important topic. This journal requires that authors assign a level of evidence to each article.

This work is a topic highlight on the surgical treatment of the right colon pathologies, focusing on the literature state of art and comparing the open surgery to the different laparoscopic and robotic procedures. Different laparoscopic procedures have been described for the treatment of right colon tumors: Totally laparoscopic right colectomy, laparoscopic assisted right colectomy, laparoscopic facilitated right colectomy, hand-assisted right colectomy, single incision laparoscopic surgery colectomy, robotic right colectomy. Two main characteristics of these techniques are the different type of anastomosis: Intracorporeal (for totally laparoscopic right colectomy, single incision laparoscopic surgery colectomy, laparoscopic assisted right colectomy and robotic technique) or extracorporeal (for laparoscopic assisted right colectomy, laparoscopic facilitated right colectomy, hand-assisted right colectomy and open right colectomy) and the different incision (suprapubic, median or transverse on the right side of abdomen). The different laparoscopic techniques meet the same oncological criteria of radicalism as the open surgery for the right colon. The totally laparoscopic right colectomy with intracorporeal anastomosis and even more the single incision laparoscopic surgery colectomy, remain a technical challenge due to the complexity of procedures (especially for the single incision laparoscopic surgery colectomy) and the particular right colon vascular anatomy but they seem to have some theoretical advantages compared to the other laparoscopic and open procedures. Data reported in literature while confirming the advantages of laparoscopic approach, do not allow to solve controversies about which is the best laparoscopic technique (Intracorporeal vs Extracorporeal Anastomosis) to treat the right colon cancer. However, the laparoscopic techniques with intracorporeal anastomosis for the right colon seem to show some theoretical advantages (functional, technical

Neonatal pain and injury can alter long-term sensory thresholds. Descending rostroventral medulla (RVM) pathways can inhibit or facilitate spinal nociceptive processing in adulthood. As these pathways undergo significant postnatal maturation, the authors evaluated long-term effects of neonatal surgical injury on RVM descending modulation. Plantar hind paw or forepaw incisions were performed in anesthetized postnatal day (P)3 Sprague-Dawley rats. Controls received anesthesia only. Hind limb mechanical and thermal withdrawal thresholds were measured to 6 weeks of age (adult). Additional groups received pre- and post-incision sciatic nerve levobupivacaine or saline. Hind paw nociceptive reflex sensitivity was quantified in anesthetized adult rats using biceps femoris electromyography, and the effect of RVM electrical stimulation (5-200 μA) measured as percentage change from baseline. In adult rats with previous neonatal incision (n = 9), all intensities of RVM stimulation decreased hind limb reflex sensitivity, in contrast to the typical bimodal pattern of facilitation and inhibition with increasing RVM stimulus intensity in controls (n = 5) (uninjured vs. neonatally incised, P < 0.001). Neonatal incision of the contralateral hind paw or forepaw also resulted in RVM inhibition of hind paw nociceptive reflexes at all stimulation intensities. Behavioral mechanical threshold (mean ± SEM, 28.1 ± 8 vs. 21.3 ± 1.2 g, P < 0.001) and thermal latency (7.1 ± 0.4 vs. 5.3 ± 0.3 s, P < 0.05) were increased in both hind paws after unilateral neonatal incision. Neonatal perioperative sciatic nerve blockade prevented injury-induced alterations in RVM descending control. Neonatal surgical injury alters the postnatal development of RVM descending control, resulting in a predominance of descending inhibition and generalized reduction in baseline reflex sensitivity. Prevention by local anesthetic blockade highlights the importance of neonatal perioperative analgesia.

The position of the skin paddle on the breast area is a fundamental element for the breast reconstructions by latissimus dorsi flap and prosthesis implantation. Should, as Millard advocated, to recreate the initial defect and include it in the mastectomy scar or is it better in an additional incision as have others authors. This study compares the long-term morphological results of these two attitudes, with or without additional incision. Eighty-two breast reconstructions by latissimus dorsi flap and prosthesis implantation, with a mean follow-up of 9.5 years were scored from 1 to 5 by a panel of expert and non-expert. The patients scored also their own reconstruction. Various parameters of the reconstructed breast were thus evaluated. We compared the results, according to the positioning of the skin paddle: with additional incision (50 cases); without additional incision (32 cases). The characteristics of the mastectomy scar on the breast area, high or low, horizontal or oblique, defined 6 groups where the results of the 2 surgical options were compared. Only the reconstructions with additional incision get significantly higher results than those without additional incision (P<0.05). This involves the two panels, in the case of high mastectomy scars. In the others cases the additional incision is not essential. If the realization of an additional incision can be perceived like misfit on an area already "mutilated", we plead for this solution in selected cases. This provides a benefit stable in time, in terms of overall results, shape and even rendering scar. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Single-incision laparoscopic surgery (SILS) is a feasible and safe procedure for colorectal cancer. However, SILS has some technical limitations such as collision between instruments and inadequate countertraction. We present a hybrid single-incision laparoscopic surgery (hybrid SILS) technique for colon cancer that involves use of one additional 5 mm trocar. Hybrid SILS for colon cancer was attempted in 70 consecutive patients by a single surgeon between August 2014 and July 2016 at Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine. Using prospectively collected data, an observational study was performed on an intention-to-treat basis. Hybrid SILS was technically completed in 66 patients, with a failure rate of 5.7% (4/70). One patient was converted to open surgery for para-aortic lymph node dissection. Another was converted to open surgery due to severe peritoneal adhesion. An additional trocar was inserted for adhesiolysis in the other two cases. Median lengths of proximal and distal margins were 12.8 cm (interquartile range [IQR], 10.0-18.6), and 8.2 cm (IQR, 5.5-18.3), respectively. Median total number of lymph nodes harvested was 24 (IQR, 18-33). Overall rate of postoperative morbidity was 12.9%, but there were no Clavien-Dindo grade III or IV complications. There was no postoperative mortality or reoperation. Median postoperative hospital stay was 6 days (IQR, 5-7). Hybrid SILS using one additional 5 mm trocar is a safe and effective minimally invasive surgical technique for colon cancer. Experienced laparoscopic surgeons can perform hybrid SILS without a learning curve based on the formulaic surgical techniques presented in this article.

Use of electronic transmitter and monitoring systems to track movements of aquatic animals has increased continuously since the inception of these systems in the mid-1950s. The purpose of the present report is to provide information about veterinary principles and their incorporation into surgical implantation procedures for fish. We also intend to provide insight into the unique challenges of field-based aquatic surgical studies. Within this context, 4 aspects of the process for surgical implantation of transmitters in fish (ie, handling, aseptic technique, anesthesia, and implantation) will be described. Effects of surgical insertion of transmitters (ie, tagging) and aspects of the surgical implantation process where collaboration and professional exchanges among nonveterinarian researchers and veterinarians may be most fruitful will be discussed. Although this report focuses on surgical implantation, the principles and protocols described here (other than incision and suture placement) are also applicable to studies that involve injection of transmitters into fish.

This study evaluated the surgical performance of a 405-nm diode laser in vivo, using living rat liver tissue. Tissue was incised by irradiation with the laser at low output power ranging from 1 W (722 W/cm2) to 3 W (2165 W/cm2) on a manual control at a rate of 1 mm/s. As a control, incisions using a stainless scalpel were compared. Immediately after operation, the surface of the incisions was macroscopically observed and histopathologically evaluated by microscopy. Laser-ablated liver tissue was smooth with observable signs of remnant carbonization and easily acquired hemostasis. The thickness of the denatured layer increased in proportion to the output power; the coagulation layer did not thicken accordingly. Bleeding could not be stopped for tissues incised with the stainless scalpel. The 405-nm diode laser thus proved to be effective for ablating soft tissue with high hemostatic ability at low power.

Two pilot trials and one study in a closely related grebe species suggest that Western grebes (Aechmophorus occidentalis) will not tolerate intracoelomic transmitter implantation with percutaneous antennae and often die within days of surgery. Wild Western grebes (n = 21) were captured to evaluate a modified surgical technique. Seven birds were surgically implanted with intracoelomic transmitters with percutaneous antennae by using the modified technique (transmitter group), 7 received the same surgery without transmitter implantation (celiotomy group), and 7 served as controls (only undergoing anesthesia). Modifications included laterally offsetting the body wall incision from the skin incision, application of absorbable cyanoacrylate tissue glue to the subcutaneous space between the body wall and skin incisions, application of a waterproof sealant to the skin incision after suture closure, and application of a piece of porcine small intestine submucosa to the antenna egress. Survival did not differ among the 3 groups with 7 of 7 control, 6 of 7 celiotomy, and 6 of 7 transmitter birds surviving the 9-day study. Experimental birds were euthanized at the end of the study, and postmortem findings indicated normal healing. Significant differences in plasma chemistry or immune function were not detected among the 3 groups, and only minor differences were detected in red blood cell indices and plasma proteins. After surgery, the birds in the transmitter group spent more time preening tail feathers than those in the control and celiotomy groups. These results demonstrate that, in a captive situation, celiotomy and intracoelomic transmitter implantation caused minimal detectable homeostatic disturbance in this species and that Western grebes can survive implantation of intracoelomic transmitters with percutaneous antennae. It remains to be determined what potential this modified surgical procedure has to improve postoperative survival of Western grebes that are

Laparoscopic appendectomy is accepted as the gold standard technique for the treatment of acute appendicitis. Recently single-incision laparoscopic surgery (SILS) was tried in the pediatric population and was shown to be both feasible and safe. We describe our early experience in teaching the SILS procedure for appendicitis in a large community hospital center surgical residency program. SILS appendectomy was performed in 40 consecutive patients with acute appendicitis who were admitted by a single surgeon from May 2011 to August 2011. All patients over the age of 4 y presenting with noncomplicated and complicated appendicitis (perforated) were offered SILS appendectomy. Execution of the technical aspects of 20 SILS operations done by 3 PGY III residents was evaluated. The average age of the patient was 11.1 y (range, 7 to 15). SILS was performed successfully in 19 out of 20 patients. Nineteen patients underwent emergent or urgent appendectomy, while 1 patient underwent an interval procedure. Nine patients were found to have perforated appendicitis, while the other 11 had noncomplicated acute appendicitis. One patient was converted to conventional 3-port laparoscopy due to difficulties during the procedure. The mean operative time was 73 min (range, 47 to 112). A significant learning curve to successfully execute the critical steps of the SILS procedure was noted in all residents evaluated. SILS technology appears promising for the treatment of acute appendicitis. However, its successful incorporation into surgical training programs will depend on the development of innovative simulation strategies.

The common method of closing conjunctival incisions is by suturing, which is associated with several disadvantages. It requires skill to apply and does not always provide a watertight closure, which is required in some operations (e.g., glaucoma filtration). The purpose of the present study was to evaluate laser soldering as an alternative method for closing conjunctival incisions. Conjunctival incisions of 20 ex vivo porcine eyes were laser soldered using a temperature-controlled fiberoptic laser system and an albumin mixed with indocyanine green as a solder. The control group consisted of five repaired incisions by a 10-0 nylon running suture. The leak pressure of the repaired incisions was measured. The mean leak pressure in the laser-soldered group was 132 mm Hg compared to 4 mm Hg in the sutured group. There was no statistically significant difference in both the incision's length and distance from the limbus between the groups, before and after the procedure, indicating that there was no severe thermal damage. These preliminary results clearly demonstrate that laser soldering may be a useful method for achieving an immediate watertight conjunctival wound closure. This procedure is faster and easier to apply than suturing.

Within only a few decades from its initial introduction, the field of surgical robotics has evolved into a dynamic and rapidly growing research area with increasing clinical uptake worldwide. Initially introduced for stereotaxic neurosurgery, surgical robots are now involved in an increasing number of procedures, demonstrating their practical clinical potential while propelling further advances in surgical innovations. Emerging platforms are also able to perform complex interventions through only a single-entry incision, and navigate through natural anatomical pathways in a tethered or wireless fashion. New devices facilitate superhuman dexterity and enable the performance of surgical steps that are otherwise impossible. They also allow seamless integration of microimaging techniques at the cellular level, significantly expanding the capabilities of surgeons. This paper provides an overview of the significant achievements in surgical robotics and identifies the current trends and future research directions of the field in making surgical robots safer, smaller, and smarter.

High-intensity focused ultrasound in obstetrics and gynecology: the birth of a new era of noninvasive surgery?

Although ultrasound is an essential investigative modality in obstetrics and gynecology, the potential for therapeutic high-intensity focused ultrasound (HIFU) (also referred to as focused ultrasound surgery, FUS) to offer an alternative to invasive surgery is less well known. The ability of HIFU to create discrete regions of tissue necrosis only in precisely targeted positions by careful placement of the focus, without the need for any surgical intervention, has made HIFU of interest to those seeking noninvasive alternatives to conventional abdominal surgery. This article reviews the current experimental and clinical experience with HIFU in obstetrics and gynecology, and outlines potential future applications in fetal medicine and the challenges faced in their development. © Georg Thieme Verlag KG Stuttgart · New York.

To evaluate the effect of surgical factors on postoperative astigmatism in infants undergoing cataract extraction with or without intraocular lens (IOL) implantation. The Infant Aphakia Treatment Study is a multicenter clinical trial in which 114 infants with unilateral congenital cataracts were randomized to undergo cataract extraction with IOL placement or contact lens aphakic correction. Surgical videos were reviewed with regard to incision type and location, whether the incision was extended, the number of sutures placed, and technique of closure. Corneal astigmatism was measured using a handheld keratometer prior to surgery and at 1 year of age. Corneal astigmatism decreased from a mean of 1.92 D at baseline to 1.62 D at age 1 year in the contact lens group but remained almost unchanged from 2.00 D to 2.09 D in the IOL group (P = 0.023). There was no statistical difference between the amount of corneal astigmatism with regard to incision type (P = 0.214) and no increase in astigmatism with extension of the incision to facilitate IOL placement (P = 0.849) at 1 year. The number of sutures and technique of closure did not influence the amount of astigmatism at 1 year. At the age of 1 year following cataract extraction in infants, contact lens correction and the lack of IOL placement are associated with a significant decrease in postoperative corneal astigmatism compared to IOL placement. No other surgical factors considered in this study had a statistically significant effect on corneal astigmatism. Copyright © 2014 American Association for Pediatric Ophthalmology and Strabismus.

Objectives We retrospectively reviewed the evolution of segmentectomy for pulmonary tuberculosis (TB) and the feasibility of multi- and single-incision video-assisted thoracoscopic segmentectomy. Methods Of 348 patients undergoing surgery for TB, the medical records of 121 patients undergoing segmentectomy between January 1996 and November 2015 were reviewed. Clinical information and computed tomography (CT) image characteristics were investigated and analyzed. Results Eighteen patients underwent direct or intended thoracotomy. Sixty-four underwent video-assisted thoracoscopic segmentectomy (VATS), including 53 multi-incision thoracoscopic segmentectomy (MITS), and 11 single-incision thoracoscopic segmentectomy (SITS). Thirty-nine were converted to thoracotomy. The intended thoracotomy group had more operative blood loss (p = 0.005) and hospital stay (p = 0.001) than the VATS group although the VATS group had higher grade of cavity (p = 0.007). The intended thoracotomy group did not differ from converted thoracotomy in operative time, blood loss, or hospital stay, and the grade of pleural thickening was higher in the converted thoracotomy group (p = 0.001). The converted thoracotomy group had more operative blood loss, hospital stay, and complication rate than the MITS group (p = 0.001, p<0.001, and p = 0.009, respectively). The MITS group had lower pleural thickening, peribronchial lymph node calcification, cavity, and tuberculoma grading than the converted thoracotomy group (p<0.001, p = 0.001, 0.001, and 0.017, respectively). The SITS group had lower grading in pleural thickening, peribronchial lymph node calcification, and aspergilloma grading than the converted thoracotomy group (p = 0.002, 0.010, and 0.031, respectively). Four patients in the intended thoracotomy group and seven in the converted thoracotomy group had complications compared with three patients in the MITS and two in the SITS group. Risk factors of conversion were pleural thickening and

Obstetric providers are logical choices for conveying information about physical activity to their pregnant patients. However, research regarding obstetric providers counseling pregnant patients about physical activity is sparse. To investigate the association between obstetric providers discussing exercise with their pregnant patients and patients' exercise behaviors and to explore factors related to obstetric providers discussing exercise and other health behaviors (tobacco use, alcohol use, and nutrition) with their patients. We received completed surveys from 238 pregnant women and 31 obstetric providers at 12 obstetrician offices. The offices were located throughout the United States and were heterogeneous in regards to patient insurance coverage, number of patients treated per month, and percentage of patients with complications. Women who were "more careful about eating healthy" (odds ratio [OR], 3.1; 95% confidence interval [CI], 1.2-8.0) and who discussed exercise with their obstetric provider (OR, 2.2; 95% CI, 1.1-4.3) were more likely to "maintain or increase exercise" during pregnancy than those who were not conscientious about their diets and those who did not discuss exercise with their obstetric provider, respectively. The odds of obstetric providers discussing exercise with pregnant patients increased 7-fold (OR, 7.1; 95% CI, 1.4-37.3) for each health behavior the obstetric provider discussed with the patient. Patient discussions with obstetric providers about exercise and patient attention to eating habits are associated with exercising during pregnancy. A more multibehavioral approach by obstetric providers may improve the likelihood that patients exercise during pregnancy.

Challenges intrinsic to the accurate diagnosis of endometriosis contribute to an extended delay between the onset of symptoms and clinical confirmation. Intraoperative visualization, preferably with histologic verification, is considered by many professional organizations to be the gold standard by which endometriosis is diagnosed. Clinical diagnosis of symptomatic endometriosis via patient history, physical examination, and noninvasive tests, though more easily executed, is generally viewed as less accurate than surgical diagnosis. Technological advances and increased understanding of the pathophysiology of endometriosis warrant continuing reevaluation of the standard method for diagnosing symptomatic disease. A review of the published literature was therefore performed with the goal of comparing the accuracy of clinical diagnostic measures with that of surgical diagnosis. The current body of evidence suggests that clinical diagnosis of symptomatic endometriosis is more reliable than previously recognized and that surgical diagnosis has limitations that could be underappreciated. Regardless of the methodology used, women with suspected symptomatic endometriosis would be well served by a diagnostic paradigm that is reliable, conveys minimal risk of under- or over-diagnosis, lessens the time from symptom development to diagnosis, and guides the appropriate use of medical and surgical management strategies. © 2018 The Authors.

We present our experience on the design and development of a gynaecology and obstetrics graduate residency programme, developed in the Department of Obstetrics and Gynecology at the Dr Adolfo Prince Lara Hospital, Puerto Cabello, Venezuela, in which medical specialists and residents participate synergistically. From January to September 1993, curricular activities were planned and students selected. The programme started in October 1993, with six residents for a three-year programme. Courses were given by medical specialists from the Department. In addition to a Programme Coordinator, there is also a Residents' Coordinator, appointed for a two-month term of office; specific functions were assigned for residents occupying this position. All the programmed activities for three years were accomplished, including lectures and rotations, with an important record of surgical interventions. In our grade system, residents got an average of 18 over a maximum of 20 points. Residents also participated as speakers in workshops, special courses and national medicinal meetings, in which they presented a total of nine papers. Activities were evaluated bimonthly in meetings with students and each semester by the Graduate Committee. The first class graduated in September 1996. Results suggest that resident participation in graduate programmes is an important part of their education. PMID:9538482

Various palatoplasty techniques have limited incisions in the hard palate due to concerns that these incisions may limit maxillary growth. There is little convincing long-term evidence to support this. Our purpose is to determine incisal relationships, an indicator for future orthognathic procedure, in patients after repair of an isolated cleft of the secondary palate. Our craniofacial database was used to identify patients aged 10 years or greater with an isolated cleft of the secondary palate who underwent palatoplasty between 1985 and 2002. Data collected included age at palatoplasty and follow-up, cleft type, associated syndrome, Robin sequence, surgeon, repair technique, number of operations, and occlusion. Incisal relationship was determined through clinical observation by a pediatric dentist and orthodontist. Seventy eligible patients operated on by 9 surgeons were identified. Class III incisal relationship was seen in 5 patients (7.1%). Palatoplasty techniques over the hard palate (63 of 70 patients) included 2-flap palatoplasty, VY-pushback, and Von Langenbeck repair. There was an association between class III incisal relationship and syndromic diagnosis (P <0.001). Other study variables were not associated with class III incisal relationships. In patients with an isolated cleft of the secondary palate, there was no association between class III incisal relationship and surgeon, age at repair, cleft type, palatoplasty technique, or number of operations. Increased likelihood of class III incisal relationship was associated primarily with syndromic diagnosis.

The main aspect of concern for upper GI procedures has been the retraction of the liver especially large left lobes as commonly encountered in Bariatric surgery. Not doing so would compromise the view of the hiatus, hence theoretically reducing the quality of the surgery and increasing the possibility of complications. The aim of this study was to review the various liver retraction techniques in single incision surgery being done at our institute and analyze them. A retrospective study of the various techniques and a subsequent analysis was made based on advantages and disadvantages of each method. Objectively a quantitative measure of hiatal exposure was done using a scoring system based on the grade of exposure after reviewing the surgical videos. From January 2011 to January 2013 total 104 patients underwent single incision surgery with the various liver retraction techniques with following grades of exposure -liver suspension tube technique with naso gastric tubing (2.11) and with corrugated drain (2.09) needlescopic method (1.2), Umbilical tape sling (1.95), crural stitch method (2.5). Needeloscopic method has the best grade of exposure and is the easiest to start with. The average time to create the liver retraction was 2.8 to 8.6 min.There was no procedure related morbidity or mortality. The mentioned liver retraction techniques are cost effective and easy to learn. We recommend using these techniques to have a good exposure of hiatus, without compromising the safety of surgery in single incision surgery.

This study aims to assess the quality of various steps of manual small incision cataract surgery and predictors of quality, using video recordings. This paper applies a retrospective study. Fifty-two trainees participated in a hands-on small incision cataract surgery training programme at rural Chinese hospitals. Trainees provided one video each recorded by a tripod-mounted digital recorder after completing a one-week theoretical course and hands-on training monitored by expert trainers. Videos were graded by two different experts, using a 4-point scale developed by the International Council of Ophthalmology for each of 12 surgical steps and six global factors. Grades ranged from 2 (worst) to 5 (best), with a score of 0 if the step was performed by trainers. Mean score for the performance of each cataract surgical step rated by trainers. Videos and data were available for 49/52 trainees (94.2%, median age 38 years, 16.3% women and 77.5% completing > 50 training cases). The majority (53.1%, 26/49) had performed ≤ 50 cataract surgeries prior to training. Kappa was 0.57∼0.98 for the steps (mean 0.85). Poorest-rated steps were draping the surgical field (mean ± standard deviation = 3.27 ± 0.78), hydro-dissection (3.88 ± 1.22) and wound closure (3.92 ± 1.03), and top-rated steps were insertion of viscoelastic (4.96 ± 0.20) and anterior chamber entry (4.69 ± 0.74). In linear regression models, higher total score was associated with younger age (P = 0.015) and having performed >50 independent manual small incision cases (P = 0.039). More training should be given to preoperative draping, which is poorly performed and crucial in preventing infection. Surgical experience improves ratings. © 2015 Royal Australian and New Zealand College of Ophthalmologists.

Composite redesign of obstetrical forceps

Due to the increase in the number of children being born recently, medical technology has struggled to keep pace in certain areas. In these areas, particular needs have arisen to which the subject of this paper is directed. In the area of obstetrics, the forceps design and function has remained relatively unchanged for a number of years. In an effort to advance the technology, NASA Marshall Space Flight Center has been asked by the obstetrical community to help in a redesign of the obstetric forceps. Traditionally the forceps design has been of tubular stainless steel, constructed in two halves which interlock and hinge to provide the gripping force necessary to aid in the delivery of an infant. The stainless steel material was used to provide for ease of cleaning and sterilization. However, one of the drawbacks of the non-flexible steel design is that excessive force can be placed upon an infants head which could result in damage or injury to the infant. The redesign of this particular obstetric tool involves applying NASA's knowledge of advanced materials and state of the art instrumentation to create a tool which can be used freely throughout the obstetrics community without the fear of injury to an infant being delivered.

The Obstetric Anaesthetists' Association and Difficult Airway Society have developed the first national obstetric guidelines for the safe management of difficult and failed tracheal intubation during general anaesthesia. They comprise four algorithms and two tables. A master algorithm provides an overview. Algorithm 1 gives a framework on how to optimise a safe general anaesthetic technique in the obstetric patient, and emphasises: planning and multidisciplinary communication; how to prevent the rapid oxygen desaturation seen in pregnant women by advocating nasal oxygenation and mask ventilation immediately after induction; limiting intubation attempts to two; and consideration of early release of cricoid pressure if difficulties are encountered. Algorithm 2 summarises the management after declaring failed tracheal intubation with clear decision points, and encourages early insertion of a (preferably second-generation) supraglottic airway device if appropriate. Algorithm 3 covers the management of the 'can't intubate, can't oxygenate' situation and emergency front-of-neck airway access, including the necessity for timely perimortem caesarean section if maternal oxygenation cannot be achieved. Table 1 gives a structure for assessing the individual factors relevant in the decision to awaken or proceed should intubation fail, which include: urgency related to maternal or fetal factors; seniority of the anaesthetist; obesity of the patient; surgical complexity; aspiration risk; potential difficulty with provision of alternative anaesthesia; and post-induction airway device and airway patency. This decision should be considered by the team in advance of performing a general anaesthetic to make a provisional plan should failed intubation occur. The table is also intended to be used as a teaching tool to facilitate discussion and learning regarding the complex nature of decision-making when faced with a failed intubation. Table 2 gives practical considerations of how to

The aim of this randomized, controlled, clinical study was to compare two surgical techniques with the acellular dermal matrix graft (ADMG) to evaluate which technique could provide better root coverage. Fifteen patients with bilateral Miller Class I gingival recession areas were selected. In each patient, one recession area was randomly assigned to the control group, while the contra-lateral recession area was assigned to the test group. The ADMG was used in both groups. The control group was treated with a broader flap and vertical-releasing incisions, and the test group was treated with the proposed surgical technique, without releasing incisions. The clinical parameters evaluated before the surgeries and after 12 months were: gingival recession height, probing depth, relative clinical attachment level and the width and thickness of keratinized tissue. There were no statistically significant differences between the groups for all parameters at baseline. After 12 months, there was a statistically significant reduction in recession height in both groups, and there was no statistically significant difference between the techniques with regard to root coverage. Both surgical techniques provided significant reduction in gingival recession height after 12 months, and similar results in relation to root coverage.

In men, the development of feminized breasts may cause significant emotional distress and embarrassment, particularly in young men and adolescents. Unfortunately, gynecomastia responds poorly to diet and exercise, and conventional corrective surgery may produce large stigmatizing areolar or chest scars and a flattened or concave chest. In 2004, board-certified plastic surgeons performed 16,275 corrective procedures, and in 2005 there was a 17% increase, according to The American Society of Plastic Surgeons (ASPS) procedural statistics. This report describes a surgical approach for removal of both glandular and adipose tissue using a small 3-mm areolar stab wound incision and a piecemeal glandular resection to correct gynecomastia with minimal and imperceptible external scarring. Pectoral etching of the chest and suction lipectomy are performed simultaneously to enhance and define the thoracic musculature and further virilize the upper thorax. Excellent results have been obtained with minimal complications. The authors present their experience with more than 200 consecutive cases over the past 4 years. They are very optimistic with these results because they have obtained a high degree of patient satisfaction.

Vaginal agenesis: an opinion on the surgical management.

Templeman, C; Hertweck, S P

2000-08-01

The management of vaginal agenesis-Mayer-Rokitanksy-Kuster-Hauser syndrome-has always been a controversial topic. Initially, the arguments centered on whether to do surgery or try passive dilation as well as at what age to intervene. As surgical techniques have recently become refined, the question is, if surgery is selected, what type of tissue should one use (bowel vs. skin graft) and, if skin graft, from what area to select. Now we are faced with new surgical techniques from the realm of pelviscopy and ask the question: Is one of these better than the other, and is this approach superior to previously established surgical techniques? Drs. Claire Templeman and S. Paige Hertweck from the University of Louisville School of Medicine, Department of Obstetrics and Gynecology here present a concise discussion of these diverse issues.

Purpose Various palatoplasty techniques have limited incisions in the hard palate due to concerns that these incisions may limit maxillary growth. There is little convincing long-term evidence to support this. Our purpose is to determine incisal relationships, an indicator for future orthognathic procedure, in patients after repair of an isolated cleft of the secondary palate. Methods Our craniofacial database was used to identify patients aged ten years or greater with an isolated cleft of the secondary palate who underwent palatoplasty between 1985 and 2002. Data collected included age at palatoplasty and follow-up, cleft type, associated syndrome, Robin sequence, surgeon, repair technique, number of operations, and occlusion. Incisal relationship was determined through clinical observation by a pediatric dentist and orthodontist. Results Seventy eligible patients operated on by 9 surgeons were identified. Class III incisal relationship was seen in 5 patients (7.1%). Palatoplasty techniques over the hard palate (63 of 70 patients) included two-flap palatoplasty, VY-pushback, and Von Langenbeck repair. There was an association between class III incisal relationship and syndromic diagnosis (p < 0.001). Other study variables were not associated with class III incisal relationships. Conclusion In patients with an isolated cleft of the secondary palate, there was no association between class III incisal relationship and surgeon, age at repair, cleft type, palatoplasty technique, or number of operations. Increased likelihood of class III incisal relationship was associated primarily with syndromic diagnosis. PMID:27171942

This study aimed to evaluate the location and characteristics of mental foramen, anterior loop and mandibular incisive canal using cone beam computed tomography (CBCT). This retrospective cross-sectional study evaluated 200 mandibular CBCT scans for the location of mental foramen, anterior loop prevalence and mandibular incisive canal visibility, its mean length and distance to buccal and lingual plates and inferior border of the mandible. The effect of age and gender on these variables was also analyzed (P<0.05). Anterior loop and mandibular incisive canal were seen in 59.5% and 97.5% of the cases, respectively. The mean length of the mandibular incisive canal was 10.48±4.53mm in the right and 10.40±4.52mm in the left side. The mean distance from the endpoints of the canal to buccal plate was 3.63±1.73mm in the right and 3.66±1.45mm in the left side. These distances were 3.89±1.53mm in the right and 4.13±1.48mm in the left side to lingual plate and 9.98±2.07mm in the right and 8.62±1.97mm in the left side to the inferior border of the mandible. The distance from the endpoints of the canal to lingual plate was significantly different in the right and left sides. The distance from the endpoint of the canal to the buccal plate and inferior border of the mandible was significantly shorter in females (P=0.016), and had a weak, significant correlation with age (rsp=0.215, P=0.003). Due to variability in mandibular incisive canal length and high prevalence of anterior loop, CBCT is recommended before surgical manipulation of interforaminal region.

To describe the role of task delegation in the practice of major obstetric procedures in the Bogodogo health district hospital. This descriptive and analytic prospective study took place in the hospital's department of obstetrics and gynecology from February through October 2013. It included all women undergoing a major obstetric surgical intervention, performed by either by a gynecologist-obstetrician or by a nurse specializing in surgery. Data were collected from individual records and analyzed by SPSS and Epidata software. There were 601 major obstetric interventions during the study period. The women's mean age was 26.7 years. Cesarean deliveries accounted for 90% of these procedures, followed by laparotomy (7.7%). The Misgav-Ladach technique was used for cesareans by 86.5% of the obstetricians and 95.3% of the nurses specialized in surgery. The primary complications were anemia and postpartum hemorrhage. Maternal mortality did not differ significantly between the groups of operators, nor did maternal, fetal, and neonatal outcomes. Task delegation in obstetric surgery at the Bogodogo district hospital is effective. Its extension to the national level would make it possible to overcome the lack of highly qualified human resources to enable adequate availability of major obstetric interventions in rural hospitals.

Obstetric brachial plexus injury

2011-01-01

Obstetric brachial plexus injury (OBPI), also known as birth brachial plexus injury (BBPI), is unfortunately a rather common injury in newborn children. Incidence varies between 0.15 and 3 per 1000 live births in various series and countries. Although spontaneous recovery is known, there is a large subset which does not recover and needs primary or secondary surgical intervention. An extensive review of peer-reviewed publications has been done in this study, including clinical papers, review articles and systematic review of the subject. In addition, the authors’ experience of several hundred cases over the last 15 years has been added and has influenced the ultimate text. Causes of OBPI, indications of primary nerve surgery and secondary reconstruction of shoulder, etc. are discussed in detail. Although all affected children do not require surgery in infancy, a substantial proportion of them, however, require it and are better off for it. Secondary surgery is needed for shoulder elbow and hand problems. Results of nerve surgery are very encouraging. Children with OBPI should be seen early by a hand surgeon dealing with brachial plexus injuries. Good results are possible with early and appropriate intervention even in severe cases. PMID:22279269

To analyze the effect of cosmetic outcome as an isolated variable in patients undergoing surgical treatment based on the incision used in the 3 variants of radical prostatectomy: open (infraumbilical incision and Pfannestiel incision) and laparoscopic, or robotic (6 ports) surgery. 612 male patients 40 to 70 years of age with a negative history of prostate disease were invited to participate. Each patient was evaluated by questionnaire accompanied by a set of 6 photographs showing the cosmetic appearance of the 3 approaches, with and without undergarments. Participants ranked the approaches according to preference, on the basis of cosmesis. We also recorded demographic variables: age, body mass index, marital status, education level, and physical activity. Of the 577 patients who completed the questionnaries, the 6-port minimally invasive approach represents the option preferred by 52% of the participants, followed by the Pfannestiel incision (46%), and the infraumbilical incision (11%), respectively. The univariate and multivariate analyses did not show statistically significant differences when comparing the approach preferred by the patients and the sub-analyses for demographic variables, except for patients who exercised who preferred the Pfannestiel incision (58%) instead of minimally invasive approach (42%) with statistically significant differences. The minimally invasive approach was the approach of choice for the majority of patients in the treatment of prostate cancer. The Pfannestiel incision represents an acceptable alternative. More research and investment may be necesary to improve cosmetic outcomes.

The purpose of this paper is to examine whether the current surgical reimbursement system in Japan reflects resource utilization after the revision of fee schedule in 2014. The authors collected data from all the surgical procedures performed at Teikyo University Hospital from April 1 through September 30, 2014. The authors defined the decision-making unit as a surgeon with the highest academic rank in the surgery. Inputs were defined as the number of medical doctors who assisted surgery, and the time of operation from skin incision to closure. An output was defined as the surgical fee. The authors calculated surgeons' efficiency scores using data envelopment analysis. The efficiency scores of each surgical specialty were significantly different (p=0.000). This result demonstrates that the Japanese surgical reimbursement scales still fail to reflect resource utilization despite the revision of surgical fee schedule.

Lateral Erosion Encourages Vertical Incision in a Bimodal Alluvial River

NASA Astrophysics Data System (ADS)

Gran, K. B.

2015-12-01

Sand can have a strong impact on gravel transport, increasing gravel transport rates by orders of magnitude as sand content increases. Recent experimental work by others indicates that adding sand to an armored bed can even cause armor to break-up and mobilize. These two elements together help explain observations from a bimodal sand and gravel-bedded river, where lateral migration into sand-rich alluvium breaks up the armor layer, encouraging further incision into the bed. Detailed bedload measurements were coupled with surface and subsurface grain size analyses and cross-sectional surveys in a seasonally-incised channel carved into the upper alluvial fan of the Pasig-Potrero River at Mount Pinatubo, Philippines. Pinatubo erupted in 1991, filling valleys draining the flanks of the volcano with primarily sand-sized pyroclastic flow debris. Twenty years after the eruption, sand-rich sediment inputs are strongly seasonal, with most sediment input to the channel during the rainy season. During the dry season, flow condenses from a wide braided planform to a single-thread channel in most of the upper basin, extending several km onto the alluvial fan. This change in planform creates similar unit discharge ranges in summer and winter. Lower sediment loads in the dry season drive vertical incision until the bed is sufficiently armored. Incision proceeds downstream in a wave, with increasing sediment transport rates and decreasing grain size with distance downstream, eventually reaching a gravel-sand transition and return to a braided planform. Incision depths in the gravel-bedded section exceeded 3 meters in parts of a 4 km-long study reach, a depth too great to be explained by predictions from simple winnowing during incision. Instead, lateral migration into sand-rich alluvium provides sufficient fine sediment to break up the armor surface, allowing incision to start anew and increasing the total depth of the seasonally-incised valley. Lateral migration is recorded in a

Higher cost of single incision laparoscopic cholecystectomy due to longer operating time. A study of opportunity cost based on meta-analysis

GIRABENT-FARRÉS, M.

2018-01-01

Background We aimed to calculate the opportunity cost of the operating time to demonstrate that single incision laparoscopic cholecystectomy (SILC) is more expensive than classic laparoscopic cholecystectomy (CLC). Methods We identified studies comparing use of both techniques during the period 2008–2016, and to calculate the opportunity cost, we performed another search in the same period of time with an economic evaluation of classic laparoscopy. We performed a meta-analysis of the items selected in the first review considering the cost of surgery and surgical time, and we analyzed their differences. We subsequently calculated the opportunity cost of these time differences based on the design of a cost/time variable using the data from the second literature review. Results Twenty-seven articles were selected from the first review: 26 for operating time (3.138 patients) and 3 for the cost of surgery (831 patients), and 3 articles from the second review. Both techniques have similar operating costs. Single incision laparoscopy surgery takes longer (16.90min) to perform (p <0.00001) and this difference represents an opportunity cost of 755.97 € (cost/time unit factor of 44.73 €/min). Conclusions SILC costs the same as CLC, but the surgery takes longer to perform, and this difference involves an opportunity cost that increases the total cost of SILC. The value of the opportunity cost of the operating time can vary the total cost of a surgical technique and it should be included in the economic evaluation to support the decision to adopt a new surgical technique.

Axillary bromhidrosis has a strong negative effect on one's social life. A high success rate and few complications are criteria for a surgical treatment. The objective of this study was to evaluate a new surgical treatment modality for bromhidrosis: subcutaneous scissor with micropore. Twenty patients with bromhidrosis were treated. Patients were placed in a supine position with their treated arms abducted to 110°. After injection of 60 mL of tumescent solution into each axilla, one small incision was made at the middle axillary of the hair-bearing area. The whole hair-bearing skin was undermined at the level of the superficial fat to obtain adequate skin eversion. The flaps were everted to offer full exposure of the apocrine glands, and meticulous excision of each gland was performed. Both sides were punctured with scalpel. The micropore was used for drainage, and whose width was just 3 mm. Finally, the incisions were re-approximated, and bulky compressive dressings were applied to the area for 72 hours. Of the 40 axillae (20 patients), 34 (85.0%) showed excellent results, and six (15.0%) had good results. Malodor was significantly decreased. There were no serious complications. This technique can produce excellent results with a lower complication rate than most other surgical modalities and can be performed without costly equipment. © 2017 Wiley Periodicals, Inc.

Femtosecond-Assisted Arcuate Keratotomy for the Correction of Postkeratoplasty Astigmatism: Vector Analysis and Accuracy of Laser Incisions.

2015-09-01

To assess the clinical and refractive outcomes of femtosecond-assisted arcuate keratotomy in postkeratoplasty patients, and the accuracy of the incisions, using optical coherence tomography. This is a retrospective study of patients with high postkeratoplasty astigmatism. Patients with a minimum of 4 diopters (D) of postkeratoplasty regular astigmatism were included. The main outcome measures were corrected distance visual acuity, keratometry, corneal topography, and the depth of corneal incisions. Arcuate keratotomy procedures were performed using the IntraLase Femtosecond laser. The depth of keratotomies was set to 75% of the thinnest pachymetry. Twenty eyes of 20 patients were recruited in this study. The mean age at surgery was 51 years, and the mean follow-up period was 17 ± 7.9 months. The corrected distance visual acuity improved significantly from 20/60 preoperatively to 20/41 after surgery (P = 0.004). The mean preoperative and postoperative spherical equivalents were -4.34 ± 2.91 D and -4.44 ± 3.64 D, respectively (P = 0.49). The mean keratometric cylinder decreased from 9.45 ± 2.97 D (range, 4.2-15.2 D) to 4.64 ± 2.79 D (range, 1.4-11.8 D) (P < 0.001). There was no statistical difference between the mean surgical-induced astigmatism and the mean target-induced astigmatism (P = 0.313). The mean difference between the scheduled and actual incision depth was 10.5 ± 22.2 μm (P = 0.057). No complications occurred during the procedures. Femtosecond-assisted keratotomy seems to be a safe and efficient technique for the reduction of large amounts of corneal astigmatism. Although overcorrection and undercorrection may occur, the visual outcome is satisfactory. Optical coherence tomography analysis reports a good predictability of the depth of incisions.

Surgical trauma produces metabolic and hormonal responses, which are characterized by insulin resistance. Due to extension of the preoperative fasting period, which increases the magnitude of postoperative insulin resistance, preoperative oral carbohydrates (POC) have been developed. This prospective, randomized, controlled study was performed on 43 ASA I-II patients undergoing elective microsurgical lumbar discectomy. The intervention group received oral carbohydrate solution 800mL the night before and 400mL 2h prior to operation. The other group fasted for 8h prior to operation. Blood samples were obtained the day before the operation, before induction of anesthesia, after skin incision, 1h, 2h, 6h and 24h following skin incision. Blood glucose, plasma insulin, cortisol and interleukin-6 (IL-6) levels were determined. The primary endpoint was to assess the effect of POC treatment on insulin resistance and surgical stress response following lumbar disc surgery. The secondary endpoint was to assess POC's effects on postoperative nausea and vomiting. The serum insulin levels were higher before induction of anesthesia in the study group and returned to fasted group levels by 2h after skin incision. The plasma IL-6 levels were higher in the intervention group at 6h after the skin incision. There were no differences between the two groups with respect to blood glucose, plasma cortisol levels and the incidence of nausea and vomiting. This study suggests that use of POC treatment does not attenuate development of insulin resistance in patients undergoing lumbar disc surgery. Copyright © 2016. Published by Elsevier B.V.

It was a prolapse in 9 cases (reconfection of the colostomy: 6 cases, restoration of digestive continuity: 3 cases), a necrosis in 5 cases (reconfection of the colostomy), a plicature in 2 cases (reconfection of the colostomy) a peristomal abscess in 2 cases (reconfection of the colostomy: 1 case, restoration of digestive continuity: 1 case) and a strangulated parastomal hernia in 1 case (herniorrhaphy). The elective incision and the perineal disease were risk factors for the occurrence of prolapse stomial. Surgical complications of colostomies remain a rare event. Prolapse is the most common complication, and it is mainly related to elective approach. Reoperation is often required especially in cases of early complications, with usually uneventful postoperative course.

To determine the effect of conjunctival incision location on the long-term efficacy of nonvalved glaucoma drainage devices. We conducted a retrospective review of patients ≥18 years of age with uncontrolled glaucoma [intraocular pressure (IOP) ≥18 mm Hg] who underwent glaucoma drainage device implantation. A comparison was made of a limbal-based (LB-BGI) versus fornix-based (FB-BGI) conjunctival flap during placement of a 350-mm Baerveldt glaucoma implant (AMO, Santa Ana, CA) in subjects with at least 1 year of follow-up data. The primary outcome measure was IOP; secondary outcome measures were medication burden, visual acuity, and surgical complications. One hundred sixty eyes of 147 glaucoma patients were included. Two years after surgery, the IOP in the LB-BGI group was 14.3±5.3 mm Hg and in the FB-BGI group 13.1±4.7 mm Hg (P=0.47). Overall success of IOP control was achieved at the final visit (range 1 to 5 y) in 90% of the LB-BGI group and 87% of the FB-BGI group (P=0.63). The medication burden of the 2 groups at 1 and 2 years after surgery was not statistically significantly different. Worsening of visual acuity by more than 2 lines was not statistically different between the groups 2 years after the surgery and at the final visit (P=0.47, P=0.60, respectively). A greater number of eyes developed endophthalmitis and were more likely to undergo subsequent tube revision in the FB-BGI group, but the differences were not significant. Both incision techniques were equally effective in controlling IOP. Each surgical approach has its advantages and this study suggests that either technique may be used safely and effectively.

Land use practices have caused stream channel incision and water table decline in many montane meadows of the Western United States. Incision changes the magnitude and timing of streamflow in water supply source watersheds, a concern to resource managers and downstream water users. The hydrology of montane meadows under natural and incised conditions was investigated using watershed simulation for a range of hydrologic conditions. The results illustrate the interdependence between: watershed and meadow hydrology; bedrock and meadow aquifers; and surface and groundwater flow through the meadow for the modeled scenarios. During the wet season, stream incision resulted in less overland flow and interflow and more meadow recharge causing a net decrease in streamflow and increase in groundwater storage relative to natural meadow conditions. During the dry season, incision resulted in less meadow evapotranspiration and more groundwater discharge to the stream causing a net increase in streamflow and a decrease in groundwater storage relative to natural meadow conditions. In general, for a given meadow setting, the magnitude of change in summer streamflow and long-term change in watershed groundwater storage due to incision will depend on the combined effect of: reduced evapotranspiration in the eroded meadow; induced groundwater recharge; replenishment of dry season groundwater storage depletion in meadow and bedrock aquifers by precipitation during wet years; and groundwater storage depletion that is not replenished by precipitation during wet years.

Is Personalized Medicine Achievable in Obstetrics?

Personalized medicine seeks to identify the right dose of the right drug for the right patient at the right time. Typically, individualization of therapy is based on the pharmacogenomic make-up of the individual and environmental factors that alter drug disposition and response. In addition to these factors, during pregnancy a woman’s body undergoes many changes that can impact the therapeutic efficacy of medications. Yet, there is minimal research regarding personalized medicine in obstetrics. Adoption of pharmacogenetic testing into the obstetrical care is dependent on evidence of analytical validity, clinical validity, and clinical utility. Here, we briefly present information regarding the potential utility of personalized medicine for treating the obstetric patient for pain with narcotics, hypertension, and preterm labor and discuss the impediments of bringing personalized medicine to the obstetrical clinic.

We analyze and discuss the clinical presentation, the diagnostic procedures and the surgical technique in relation to post-operative complications and results in cervico-mediastinal thyroid masses admitted in Thoracic Surgery Unit of AOU Second University of Naples from 1991 to 2006 and in Thoracic Surgery Unit of AOU "S. Giovanni di Dio & Ruggi D'Aragona" of Salerno over a period of 3 years (2011-2014). We reviewed 97 patients who underwent surgical treatment for cervico-mediastinal goiters. 47 patients (49.2%) had cervico-mediastinal goiter, 40 patients (40%) had mediastino-cervical goiter and 10 patients (10.8%) had mediastinal goiter. 73 cases were prevascular goiters and 24 were retrovascular goiters. We performed total thyroidectomy in 40 patients, subtotal thyroidectomy in 46 patients and in 11 cases the resection of residual goiter. In 75 patients we used only a cervical approach, in 21 patients the cervical incision was combined with median sternotomy and in 1 patient with transverse sternotomy. Three patients (3.1%) died in the postoperative period (2 cardio-respiratory failure and 1 pulmonary embolism). The histologic study revelead 8 (7.7%) carcinomas. Postoperative complications were: dyspnea in 9 cases (10.7%), transient vocal cord paralysis in 6 patients (9.2%), temporary hypoparathyroidism in 9 patients (9.2%) and kidney failure in 1 case (0.9%). The presence of a cervico-mediastinal thyroid mass with or without respiratory distress requires a surgical excision as the only treatment option. Thyroid masses extending to the mediastinum can be excised successfully by cervical incision. Bipolar approach (cervical incision and sternotomy) has an excellent outcome, achieving a safe resection, especially in large thyroid masses extending to the mediastinum with close relations to mediastinal structures and in some limited cases (carcinoma, thyroiditis, retrovascular goiter, ectopic goiter). Postoperative mortality and morbidity is very low, independent of

Physically based modeling of bedrock incision by abrasion, plucking, and macroabrasion

2009-11-01

Many important insights into the dynamic coupling among climate, erosion, and tectonics in mountain areas have derived from several numerical models of the past few decades which include descriptions of bedrock incision. However, many questions regarding incision processes and morphology of bedrock streams still remain unanswered. A more mechanistically based incision model is needed as a component to study landscape evolution. Major bedrock incision processes include (among other mechanisms) abrasion by bed load, plucking, and macroabrasion (a process of fracturing of the bedrock into pluckable sizes mediated by particle impacts). The purpose of this paper is to develop a physically based model of bedrock incision that includes all three processes mentioned above. To build the model, we start by developing a theory of abrasion, plucking, and macroabrasion mechanisms. We then incorporate hydrology, the evaluation of boundary shear stress, capacity transport, an entrainment relation for pluckable particles, a routing model linking in-stream sediment and hillslopes, a formulation for alluvial channel coverage, a channel width relation, Hack's law, and Exner equation into the model so that we can simulate the evolution of bedrock channels. The model successfully simulates various features of bed elevation profiles of natural bedrock rivers under a variety of input or boundary conditions. The results also illustrate that knickpoints found in bedrock rivers may be autogenic in addition to being driven by base level fall and lithologic changes. This supports the concept that bedrock incision by knickpoint migration may be an integral part of normal incision processes. The model is expected to improve the current understanding of the linkage among physically meaningful input parameters, the physics of incision process, and morphological changes in bedrock streams.

Immigration plays a major role in obstetrics in Austria, and about 18 % of the Austrian population are immigrants. Therefore, we aimed to (1) test the feasibility of a proposed questionnaire for assessment of migrant status in epidemiological research and (2) assess some important associations between procedures and outcomes in obstetrics and migration in selected departments in Austria. We adapted a standardized questionnaire to the main immigration groups in Austria. Information on country of origin, length of residence in Austria and German-language ability was collected from eight selected obstetrics departments. Of the 1,971 questionnaires, 1,873 questionnaires of singleton births were selected and included in the analysis. We analyzed a total of 1,873 parturients with singleton births, of which 35 % had migrant status, 12 % were from ex-Yugoslavia, 12 % were from Turkey, and 12 % were from other countries. The proportion of parturients having their first care visit after the 12th week of pregnancy was higher in migrant groups (19 %). Smoking was highest in the migrants from ex-Yugoslavia (21 %). Vaginal delivery was more frequent in migrants from ex-Yugoslavia (78 %) and Turkey (83 %) than in nonmigrants (71 %) and episiotomy was more frequently performed in migrants from other countries. All differences are statistically significant. Administration of a standardized questionnaire for assessment of migrant status in obstetric departments in Austria was shown to be feasible. We assessed differences in obstetric care and outcome and consequently recommend that action should be initiated in Austria toward harmonizing obstetric procedures among the migrant and the nonmigrant groups and toward minimizing risk factors.

To evaluate surgically induced astigmatism as computed by means of either simulated keratometry (K SIM ) or total corneal refractive power (TCRP) after temporal incisions. Prospective observational study including 36 right eyes undergoing cataract surgery. Astigmatism was measured preoperatively during the 3-month follow-up period using Pentacam. Surgically induced astigmatism was computed considering anterior corneal surface astigmatism at 3 mm with K SIM and considering both corneal surfaces with TCRP from 1 to 8 mm (TCRP 3 for 3 mm). The eyes under study were divided into two balanced groups: LOW with K SIM astigmatism <0.90 D and HIGH with K SIM astigmatism ≥0.90 D. Resulting surgically induced astigmatism values were compared across groups and measuring techniques by means of flattening, steepening, and torque analysis. Mean surgically induced astigmatism was higher in the HIGH group (0.31 D @ 102°) than in the LOW group (0.04 D @ 16°). The temporal incision resulted in a steepening in the HIGH group of 0.15 D @ 90°, as estimated with K SIM , versus 0.28 D @ 90° with TCRP 3 , but no significant differences were found for the steepening in the LOW group or for the torque in either group. Differences between K SIM - and TCRP 3 -based surgically induced astigmatism values were negligible in LOW group. Surgically induced astigmatism was considerably higher in the high-astigmatism group and its value was underestimated with the K SIM approach. Eyes having low astigmatism should not be included for computing the surgically induced astigmatism because steepening would be underestimated.

The clinical role of hyperoxia for preventing surgical site infection (SSI) remains uncertain because randomized controlled trials on this topic have reported disparate results. One of the principal reasons for this outcome may be that prior trials have entered heterogeneous populations of patients and a variety of procedures. The aim of our study was to assess the influence of hyperoxygenation on SSI using a homogeneous study population. From January 2004 to April 2013, we studied, in a randomized trial, 239 patients, who underwent open surgery for perforated peptic ulcer (PPU). The surgical procedure was performed through an upper abdominal midline incision, and closure of PPU was achieved by suture alone or in combination with an omental patch. Patients were assigned randomly to an oxygen/air mixture with a fraction of inspired oxygen (FiO2) of 30% (n = 120) or 80% (n = 119). Administration was commenced after induction of anesthesia and maintained for 6 hours after surgery. The overall incision infection rate was 38.4% (92 of 239): 61 patients (50.8%) had an infection in the 30% FiO2 group and 31 (26%) in the 80% FiO2 group (p < 0.05). The risk of SSI was 48% lower in the 80% FiO2 group (relative risk 0.51; 95% confidence interval [CI] 0.28-1.08) vs 30% FiO2. Supplemental 80% FiO2 during and for 6 h after open surgery for PPU, which reduces post-operative SSI, should be considered part of ongoing quality improvement activities related to surgical care, with few risks to the patient and little associated cost.

Perioperative hypothermia and incidence of surgical wound infection: a bibliographic study

The purpose of this review article was to understand and analyze the scientific production related to the occurrence of perioperative hypothermia and the incidence of infection on the surgical site. For this purpose, a search was conducted in the databases LILACS, MEDLINE, PubMed, CINAHL and Cochrane, using the health science descriptors DECS, from 2004 to 2009. A total of 91 articles were found. After eliminating duplicate items and using selection criteria for inclusion, six manuscripts remained for analysis. The studies were classified as retrospective, prospective, case studies, and clinical trials. After analysis, the majority of studies showed that hypothermia must be prevented during the perioperative period to reduce complications in the healing process of the surgical incision. Therefore, unadverted hypothermia directly influences in surgical site healing, increasing the incidence of infection in the surgical wound. PMID:25628208

Surgical site infection is one of the most common complications for patients after sacrectomy, which often accompanied by poor wound healing, sinus formation and serious metabolic disturbance. We tried to avoid the surgical site infection caused by feces during early period after surgery through early fasting and total parenteral nutrition (TPN) support, then compared the clinical results of these patients with other patients that received enteral nutrition (EN) early after sacrectomy. Forty-eight patients after sacrectomy (the level of sacrectomy above S 2 ) were randomly divided into two groups: TPN group and EN group. The patients of two groups received different nutrition support from the first day to the seventh day after surgery, then the factors such as nutritional and metabolic status after surgery, incidence of complications as well as the time of incision healing and hospitalization were observed. The p-value of total serum protein, albumin, serum alanine aminotransferase, total bilirubin at seventh day after sacrectomy between TPN group and EN group is <0.0005. The p-value of hemoglobin at seventh day after sacrectomy between TPN group and EN group is 0.001. The p-value of total serum protein at fourteenth day after sacrectomy between TPN group and EN group is 0.003. The p-value of albumin and total bilirubin at fourteenth day after sacrectomy between TPN group and EN group is 0.001. The p-value of hemoglobin, serum alanine aminotransferase at fourteenth day after sacrectomy between TPN group and EN group is <0.0005. The incidence of gastrointestinal complication and delay of apparition of feces in EN group were lower than that in TPN group (p=0.041, p<0.0005). The incidence of surgical site infection, the time of incision healing and hospitalization in TPN group were lower than that in EN group (p=0.048, p=0.008, p<0.0005). The method of fasting and supported by TPN during the early period after sacrectomy contribute to the incision healing, meanwhile

More aesthetically acceptable treatment options have been sought to minimise the morbidity associated with open surgery for gynaecomastia. This study investigated the use of a vacuum-assisted biopsy device (VABD) and liposuction to provide minimally invasive approach. Patients diagnosed with idiopathic benign gynaecomastia referred to the Breast Care Unit of Castle Hill Hospital between June 2002 and April 2007 and requesting surgical intervention underwent VABD excision and liposuction. All patients underwent thorough investigations to exclude any underlying cause for their gynaecomastia. The procedure was carried out by a single consultant surgeon with special interest in breast surgery. An 8-G mammotome probe was advanced through a 4-mm incision positioned in the corresponding anterior axillary line to excise the glandular disc. Liposuction was performed through the same incision. Incision wounds were closed with Steristrips. A pressure dressing was applied over wound by corset and an inflatable device. Thirty-six male patients with grade I and II gynaecomastia were recruited (22 bilateral, 14 unilateral). Average age was 33.3 years (range, 16-88 years). All underwent mammotome excision and liposuction. There were no conversions to an open procedure. The average procedure time was 50.3 min (range, 30-80 min). One intra-operative complication was recorded. The minimum follow-up time was 2 months. Thirty-four patients reported excellent satisfaction, two patients had residual gynaecomastia and needed a re-do procedure. Three patients developed small haematomas that resolved spontaneously. This novel, minimally invasive, surgical approach for gynaecomastia gives excellent results with minimal morbidity.

SILS can potentially improve aesthetic outcomes without adversely affecting treatment outcomes, but these outcomes are uncertain in laparoscopic Heller-Dor surgery. We determined if the degree of patient satisfaction with aesthetic outcomes progressed with the equivalent treatment outcomes after the introduction of a single-incision approach to laparoscopic Heller-Dor surgery. We retrospectively reviewed 20 consecutive esophageal achalasia patients (multiport approach, n = 10; single-incision approach, n = 10) and assessed the treatment outcomes and patient satisfaction with the aesthetic outcomes. In the single-incision approach, thin supportive devices were routinely used to gain exposure to the esophageal hiatus. No statistically significant differences in the operating time (210.2 ± 28.8 vs 223.5 ± 46.3 min; P = 0.4503) or blood loss (14.0 ± 31.7 vs 16.0 ± 17.8 mL; P = 0.8637) were detected between the multiport and single-incision approaches. We experienced no intraoperative complications. Mild dysphagia, which resolved spontaneously, was noted postoperatively in one patient treated with the multiport approach. The reduction rate of the maximum lower esophageal sphincter pressure was 25.1 ± 34.4% for the multiport approach and 21.8 ± 19.2% for the single-incision approach (P = 0.8266). Patient satisfaction with aesthetic outcomes was greater for the single-incision approach than for the multiport approach. When single-incision laparoscopic Heller-Dor surgery was performed adequately and combined with the use of thin supportive devices, patient satisfaction with the aesthetic outcomes was higher and treatment outcomes were equivalent to those of the multiport approach. © 2015 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

Surgical technological advances in the past three decades have led to dramatic reductions in the morbidity associated with abdominal procedures and permanently altered the surgical practice landscape. Significant changes continue apace including surgical robotics, natural orifice-based surgery, and single-incision approaches. These disruptive technologies have on occasion been injurious to patients, and high-stakes assessment before adoption of new technologies would be reasonable. We reviewed the drivers for well-established psychometric techniques available for the standards-setting process. We present a series of examples that are relevant in the surgical domain including standards setting for knowledge and skills assessments. Defensible standards for knowledge and procedural skills will likely become part of surgical clinical practice. Understanding the methodology for determining standards should position the surgical community to assist in the process and lead within their clinical settings as standards are considered that may affect patient safety and physician credentialing.

The objective of the study was to evaluate the intra- and interobserver agreement among obstetric experts in court regarding the retrospective review of abnormal fetal heart rate tracings and obstetrical management of patients with abnormal fetal heart rate during labor. A total of 22 French obstetric experts in court reviewed 30 cases of term deliveries of singleton pregnancies diagnosed with at least 1 hour of abnormal fetal heart rate, including 10 cases with adverse neonatal outcome. The experts reviewed all cases twice within a 3-month interval, with the first review being blinded to neonatal outcome. For each case reviewed, the experts were provided with the obstetric data and copies of the complete fetal heart rate recording and the partogram. The experts were asked to classify the abnormal fetal heart rate tracing and to express whether they agreed with the obstetrical management performed. When they disagreed, the experts were asked whether they concluded that an error had been made and whether they considered the obstetrical management as the cause of cerebral palsy in children if any. Compared with blinded review, the experts were significantly more likely to agree with the obstetric management performed (P < .001) and with the mode of delivery (P < .001) when informed about the neonatal outcome and were less likely to conclude that an error had been made (P < .001) or to establish a link with potential cerebral palsy (P = .003). The experts' intraobserver agreement for the review of abnormal fetal heart rate tracing and obstetrical management were both mediocre (kappa = 0.46-0.51 and kappa = 0.48-0.53, respectively). The interobserver agreement for the review of abnormal fetal heart rate tracing was low and was not improved by knowledge of the neonatal outcome (kappa = 0.11-0.18). The interobserver agreement for the interpretation of obstetrical management was also low (kappa = 0.08-0.19) but appeared to be improved by knowledge of the neonatal outcome

In order to develop a minimal obstetric anaesthesia dataset based on current Australasian clinical audit best practice, we carried out a postal survey of 69 Australasian anaesthetic departments covering an obstetric service. We asked about data being collected, specifically concerning the high risk obstetric patient, epidural analgesia and postoperative anaesthetic review. Examples of any data collection forms were requested. Of the 66 responses, 35 departments (53%) were not collecting any audit data. Twenty-six of the 31 departments (84%) performing obstetric anaesthesia audit responded to our follow-up telephone survey. Eighteen departments believed that there had been an improvement in patient care as a result of their audit and 13 felt that the benefits outweighed the costs involved. However, only six departments (9%) had performed an audit cycle. The importance of feedback to patients or hospital staff and the incidence of post dural puncture headache (PDPH) were cited by some as priorities for obstetric anaesthesia audit. There was however no consistency as to what data should be collected. Many responses suggested a perceived need to collect clinical data without knowing what to do with it. Our survey has highlighted confusion between three distinct objectives; a dataset for obstetric anaesthesia record keeping, data required for continuing patient management in hospital and, a specific minimal dataset for clinical audit purposes. We conclude that current Australasian obstetric anaesthesia audit strategies are inadequate to develop a minimal dataset for cost-effective clinical audit.

High-resolution seismic records obtained in the Rio Grande do Sul coastal zone, southern Brazil, revealed that prominent valleys and channels developed in the area before the installation of actual coastal plain. Landwards, the paleoincisions can be linked with the present courses of the main river dissecting the area. Oceanwards, they can be linked with related features previously recognized in the continental shelf and slope by means of seismic and morphostructural studies. Based mainly on seismic, core data and geologic reasoning, it can be inferred that the coastal valleys were incised during forced regression events into the coastal prism deposited during previous sea level highstand events of the Quaternary. Seismic data has revealed paleovalleys up to 10 km wide and, in some places, infilled with up to 40 m thick of sediments. The results indicated two distinct periods of cut-and-fill events in the Patos Lagoon area. The filling of the younger incision system is mainly Holocene and its onset is related to the last main regressive event of the Pleistocene, when the sea level fell about 130 m below the actual position. The older incision and filling event is related to the previous regressive-transgressive events of the Middle and Late Pleistocene. The fluvial discharge fed delta systems on the shelf edge during the sea level lowstands. The subsequent transgressions drowned the incised drainage, infilling it and closing the inlets formerly connecting the coastal river to the ocean. The incised features may have played a significant role on the basin-margin architecture, facies distribution and accommodation space during the multitude of up and down sea level events of the Quaternary.

Wound healing inevitably leads to scarring, which leads to functional and cosmetic defects. It is the goal of this study to investigate the immediate use of ablative fractional CO 2 lasers to reduce post-operative scarring secondary to surgical wounds. In this prospective controlled study, 20 surgical incisions were created on each of three pigs. Fifteen of the incisions were treated with an ablative fractional CO 2 laser at one of three laser settings. The remaining five incisions served as a control. Punch biopsies were taken post-operatively over time. Digital photographs were taken of each incisional scar at each time period. Blinded evaluators used a previously verified scoring system to score photographs of the incisional scars taken at the 6 month time period. With regards to the comparison between the three individual laser treatment groups and the control, there were no statistically significant effects for treatment (P = 0.40), time (P = 0.48), or for the interaction of time and treatment (P = 0.57). With regards to the visual assessment tool, there were no statistically significant differences between treatments for Overall Appearance (P = 0.21) or for Total Score (P = 0.24). In the limited setting of this pilot study, treatment of surgical incisions with ablative fractional CO 2 lasers does not significantly lessen scar formation. In addition, photographic analysis was not able to demonstrate a significant difference. Future studies on this topic will need a larger sample size to better answer whether a statistically significant difference may exist. Lasers Surg.

Complete placenta previa (CPP) is one of the most problematic types of abnormal placenta, which is further complicated by placenta accreta or percreta that can unexpectedly lead to catastrophic blood loss, infection, multiple complications, emergency hysterectomy, and even death. The present study aimed to assess the efficacy of random placenta margin incision in controlling intraoperative and total blood loss during cesarean section for CPP women. A prospective cohort study, including a total of 100 consecutive pregnant women with CPP, was performed at a tertiary university-affiliated medical center between March 2016 and July 2017. All of them underwent random placenta margin incision, and intraoperative and total blood loss were analyzed. Through antenatal diagnosis using color Doppler, women were further divided into abnormally invasive placenta (AIP) and non-AIP groups, and anterior and posterior placenta groups. The protocol was registered with the Clinical Trial Registry under registration number NCT02695069. Mean maternal age and gestational age at delivery were 32.26 ± 5.03 years old and 36.21 ± 2.07 weeks, respectively. Total duration of the surgical procedure time was 52.50 (42.43-64.00) min. Median estimated intraoperation blood loss was 746.43 (544.44-1092.86) ml. Total blood loss was 875.00 (604.50-1196.67) ml, and 38 (38.0%) had post-partum hemorrhage. The change from baseline in the median hemoglobin level was -0.33 (6.00-13.20). No women underwent hysterectomy due to massive hemorrhage during the study period. No women had an intraoperative urinary bladder injury, postoperative wound infection, and required relaparotomy, owing to intra-abdominal bleeding. The median hospitalization time was 5.41 (4.18-7.58) d. The random placenta margin incision may be a potentially valuable surgical procedure to control the volumes of intraoperative and postoperative blood loss and reduce the incidence of postpartum hemorrhage among women with complete

Minimally invasive therapy (MIT) is one of the most important trends in modern medicine. It includes a wide range of therapies in videoscopic surgery and interventional radiology and is performed through small incisions. It reduces hospital stay-time by allowing faster recovery and offers substantially improved cost-effectiveness for the hospital and the society. However, the introduction of MIT has also led to new problems. The manipulation of structures within the body through small incisions reduces dexterity and tactile feedback. It requires a different approach than conventional surgical procedures, since eye-hand co-ordination is not based on direct vision, but more predominantly on image guidance via endoscopes or radiological imaging modalities. ARIS*ER is a multidisciplinary consortium developing a new generation of decision support tools for MIT by augmenting visual and sensorial feedback. We will present tools based on novel concepts in visualization, robotics and haptics providing tailored solutions for a range of clinical applications. Examples from radio-frequency ablation of liver-tumors, laparoscopic liver surgery and minimally invasive cardiac surgery will be presented. Demonstrators were developed with the aim to provide a seamless workflow for the clinical user conducting image-guided therapy.

Identification and management of obstetric emergencies is essential in emergency medicine (EM), but exposure to pregnant patients during EM residency training is frequently limited. To date, there is little data describing effective ways to teach residents this material. Current guidelines require completion of 2 weeks of obstetrics or 10 vaginal deliveries, but it is unclear whether this instills competency. We created a 15-item survey evaluating resident confidence and knowledge related to obstetric emergencies. To assess confidence, we asked residents about their exposure and comfort level regarding obstetric emergencies and eight common presentations and procedures. We assessed knowledge via multiple-choice questions addressing common obstetric presentations, pelvic ultrasound image, and cardiotocography interpretation. The survey was distributed to residency programs utilizing the Council of Emergency Medicine Residency Directors (CORD) listserv. The survey was completed by 212 residents, representing 55 of 204 (27%) programs belonging to CORD and 11.2% of 1,896 eligible residents. Fifty-six percent felt they had adequate exposure to obstetric emergencies. The overall comfort level was 2.99 (1-5 scale) and comfort levels of specific presentations and procedures ranged from 2.58 to 3.97; all increased moderately with postgraduate year (PGY) level. Mean overall percentage of items answered correctly on the multiple-choice questions was 58% with no statistical difference by PGY level. Performance on individual questions did not differ by PGY level. The identification and management of obstetric emergencies is the cornerstone of EM. We found preliminary evidence of a concerning lack of resident comfort regarding obstetric conditions and knowledge deficits on core obstetrics topics. EM residents may benefit from educational interventions to increase exposure to these topics.

Objective The aim of this study was to identify the relevant obstetric factors for cerebral palsy (CP) after 33 weeks’ gestation in Japan. Study design This retrospective case cohort study (1:100 cases and controls) used a Japanese national CP registry. Obstetric characteristics and clinical course were compared between CP cases in the Japan Obstetric Compensation System for Cerebral Palsy database and controls in the perinatal database of the Japan Society of Obstetrics and Gynecology born as live singleton infants between 2009 and 2011 with a birth weight ≥ 2,000 g and gestation ≥ 33 weeks. Results One hundred and seventy-five CP cases and 17,475 controls were assessed. Major relevant single factors for CP were placental abnormalities (31%), umbilical cord abnormalities (15%), maternal complications (10%), and neonatal complications (1%). A multivariate regression model demonstrated that obstetric variables associated with CP were acute delivery due to non-reassuring fetal status (relative risk [RR]: 37.182, 95% confidence interval [CI]: 20.028–69.032), uterine rupture (RR: 24.770, 95% CI: 6.006–102.160), placental abruption (RR: 20.891, 95% CI: 11.817–36.934), and preterm labor (RR: 3.153, 95% CI: 2.024–4.911), whereas protective factors were head presentation (RR: 0.199, 95% CI: 0.088–0.450) and elective cesarean section (RR: 0.236, 95% CI: 0.067–0.828). Conclusion CP after 33 weeks’ gestation in the recently reported cases in Japan was strongly associated with acute delivery due to non-reassuring fetal status, uterine rupture, and placental abruption.

Cervical necrotizing fasciitis secondary to epiglottitis is rare. The standard treatment of this severe condition has long been early and aggressive surgical debridement and adequate antimicrobial therapy. We report the case of an immunocompetent 59-year-old man who developed cervical necrotizing fasciitis as a complication of acute epiglottitis. We were able to successfully manage this patient with conservative surgical treatment (incision and drainage, in addition to antibiotic therapy) that did not involve aggressive debridement.

In 2010, the Ministry of Health (MoH) of Guinea introduced a free emergency obstetric care policy in all the public health facilities of the country. This included antenatal checks, normal delivery and Caesarean section. This study aims at assessing the changes in coverage of obstetric care according to the Unmet Obstetric Need concept before (2008) and after (2012) the implementation of the free emergency obstetric care policy in a rural health district in Guinea. We carried out a descriptive cross-sectional study involving the retrospective review of routine programme data during the period April to June 2014. No statistical difference was observed in women's sociodemographic characteristics and indications (absolute maternal indications versus non-absolute maternal indications) before and after the implementation of the policy. Compared to referrals from health centers of patients, direct admissions at hospital significantly increased from 49% to 66% between 2008 and 2012 (p = 0.001). In rural areas, this increase concerned all maternal complications regardless of their severity, while in urban areas it mainly affected very severe complications. Compared to 2008, there were significantly more Major Obstetric Interventions for Maternal Absolute Indications in 2012 (p < 0.001). Maternal deaths decreased between 2008 and 2012 from 1.5% to 1.1% while neonatal death increased from 12% in 2008 to 15% in 2012. The implementation of the free obstetric care policy led to a significant decrease in unmet obstetric need between 2008 and 2012 in the health district of Kissidougou. However, more research is needed to allow comparisons with other health districts in the country and to analyse the trends.

OBJECTIVE: To describe the experiences of female family physicians who practise obstetrics in balancing professional obligations with personal and family needs, given the unique challenges that such practice poses for these physicians. DESIGN: Qualitative study. SETTING: Ontario. PARTICIPANTS: A purposefully selected sample of nine female family physicians who met the criteria of being married, having children and currently practising obstetrics. OUTCOME MEASURES: Experiences of female family physicians and their strategies in their personal, family and professional lives that enable them to continue practising obstetrics. RESULTS: All participants continued to practise obstetrics because of the pleasure they derived from it, despite the challenges of balancing the unpredictable demands of obstetrics with their personal and family needs. To continue in obstetrics, they needed to make changes in their lives, either through a gradual, evolutionary process or in response to a critical event. Alterations to work and family arrangements permitted them to meet the challenges and led to increased satisfaction. Changes included making supportive call-group arrangements, limiting work hours and the number of births attended and securing help with household duties. CONCLUSIONS: An in-depth examination, through the use of qualitative methods, showed the reasons why some female family physicians continue to practise obstetrics despite the stressful aspects of doing so. This knowledge may be useful for women who are residents or experienced clinicians and who are considering including obstetrics in their practice. PMID:7497390

Serefeddin Sabuncuoğlu, a pioneer of surgery, is known to be the author of first illustrated surgery textbook, Cerrahiyyetu'l Haniyye (Imperial Surgery), which was written in Turkish in 1465 AD at the age of 80 years. The purpose of this article is to describe his contributions to varicose vein surgery. In addition to vascular surgery, Serefeddin Sabuncuoğlu was interested in a wide range of surgical specialities including thoracic surgery, general surgery, pediatric surgery, ophthalmology, orthopedic surgery, urologic surgery, and obstetrics and gynecology. His book was the first illustrated textbook of surgery in the Turkish medical literature, containing color illustrations of surgical procedures, incisions, and instruments. The book has been known of for only the past 60 years. There are 137 different medical observations and recommendations in Cerrahiyyetu'l Haniyye, along with translated passages from the works of Ebu Kasim-ul Zahravi (Albucasis), Al-Tasrif (Textbook of Surgery), including Sabuncuoğlu's additional original contributions. In chapter 90 of the book, Sabuncuoğlu describes lower extremity varices and their surgical treatment and provides a few color illustrations. Although not recognized and rewarded in his time, Serefeddin Sabuncuoğlu was a great surgeon in Turkish-Islamic medical history. This review demonstrates that his textbook, Cerrahiyyetu'l Haniyye, was the first illustrated textbook including various surgical procedures, incisions, and instruments of varicose vein surgery.

The improvement of antibiotic rational use in China was studied by usage analysis of combination antibiotic therapy for type I incisions in 244 hospitals. Five kinds of hospitals, including general hospital, maternity hospital, children's hospital, stomatological hospital and cancer hospital, from 30 provinces were surveyed. A systematic random sampling strategy was employed to select outpatient prescriptions and inpatient cases in 2011 and 2012. A total of 29 280 outpatient prescriptions and 73 200 inpatient cases from 244 hospitals in each year were analyzed. Data were collected with regards to the implementation of the national antibiotic stewardship program (NASP), the overall usage and the prophylactic use of antibiotic for type I incisions. Univariate analysis was used for microbiological diagnosis rate before antimicrobial therapy, prophylactic use of antibiotics for type I incision operation, and so on. For multivariate analysis, the use of antibiotics was dichotomized according to the guidelines, and entered as binary values into logistic regression analysis. The results were compared with the corresponding criteria given by the guidelines of this campaign. The antibiotic stewardship in China was effective in that more than 80% of each kind of hospitals achieved the criteria of recommended antibiotics varieties. Hospital type appeared to be a factor statistically associated with stewardship outcome. The prophylactic use of antibiotics on type I incision operations decreased by 16.22% (P<0.05). The usage of combination antibiotic therapy for type I incisions was also decreased. Region and bed size were the main determinants on surgical prophylaxis for type I incision. This national analysis of hospitals on antibiotic use and stewardship allows relevant comparisons for bench marking. More efforts addressing the root cause of antibiotics abuse would continue to improve the rational use of antibiotics in China.

To compare blade cultures in surgery for closed fracture using a single or double blade technique to determine whether the current practice of double blade technique is justified. 155 men and 29 women aged 20 to 60 (mean, 35) years who underwent surgery for closed fracture with healthy skin at the incision site were included. Patients were block randomised to the single (n=92) or double (n=92) blade technique. Blades were sent for bacteriological analysis. Outcome measures were early surgical site infection (SSI) within 30 days and cultures from the blades. The 2 groups were comparable in baseline characteristics. In the single blade group, 6 surgical blades and 2 control blades showed positive cultures; 4 patients developed SSI, but only one had a positive culture from the surgical blade (with different organism isolated from the wound culture). In the double blade group, 6 skin blades, 7 deep blades, and 0 control blade showed positive culture; only 2 patients had the same bacteria grown from both skin and deep blade. Five patients developed SSI, but only one patient had a positive culture from the deep blade (with different organism isolated from the wound culture). The difference in incidence of culture-positive blade or SSI between the 2 groups was not significant. The relative risk of SSI in the single blade group was 0.8. Positive blade culture was not associated with SSI in the single or double blade group. The practice of changing blade following skin incision has no effect on reducing early SSI in surgery for closed fracture in healthy patients with healthy skin.

Bedrock river incision occurs during floods that generate sufficient shear stress to strip riverbeds of sediment cover and erode underlying bedrock. Thresholds for incision can prevent erosion at low flows and slow down erosion at higher flows that do generate excess shear stress. Because discharge distributions typically display power-law tails, with non-negligible frequencies of floods much greater than the mean, models incorporating stochastic discharge and incision thresholds predict that discharge variability can sometimes have greater effects on long-term incision rates than mean discharge. This occurs when the commonly observed inverse scalings between mean discharge and discharge variability are weak or when incision thresholds are high. Because the effects of thresholds and discharge variability have only been documented in a few locations, their influence on long-term river incision rates remains uncertain. The Hawaiian island of Kaua'i provides an ideal natural laboratory to evaluate the effects of discharge variability and thresholds on bedrock river incision because it has one of Earth's steepest spatial gradients in mean annual rainfall and it also experiences dramatic spatial variations in rainfall and discharge variability, spanning a wide range of the conditions reported on Earth. Kaua'i otherwise has minimal variations in lithology, vertical motion, and other factors that can influence erosion. River incision rates averaged over 1.5 - 4.5 Myr timescales can be estimated along the lengths of Kauaian channels from the depths of river canyons and lava flow ages. We characterize rainfall and discharge variability on Kaua'i using records from an extensive network of rain and stream gauges spanning the past century. We use these characterizations to model long-term bedrock river incision along Kauaian channels with a threshold-dependent incision law, modulated by site-specific discharge-channel width scalings.

Obstetric analgesia for vaginal birth in contemporary obstetrics: a survey of the practice of obstetricians in Nigeria

PubMed Central

2014-01-01

Background Contemporary obstetrics in sub-Saharan Africa is yet to meet the analgesic needs of most women during child birth for a satisfactory birth experience and expectedly, obstetricians have a major role to play in achieving this. Methods This was a questionnaire-based, cross-sectional study of 151 obstetricians and gynecologists that attended the 46th Annual General Meeting and Scientific Conference of the Society of Gynaecology and Obstetrics of Nigeria (SOGON) held in Abakaliki, southeast Nigeria in November, 2012. SOGON is the umbrella body that oversees the obstetric and gynecological practice in Nigeria. Data was collated and analyzed with Epi-info statistical software, and conclusions were drawn by means of simple percentages and inferential statistics using Odds Ratio, with P-value < 0.05 at 95% Confidence Interval (CI) taken to be statistically significant. Results Of the 151 participants, males predominated; 110 (72.9%) practiced in government-owned tertiary hospitals in urban locations. Only 74 (49%) offered obstetric analgesia. Among users, only 20 (13.3%) offered obstetric analgesia routinely to parturients, 44 (29.1%) sometimes and 10 (6.6%) on patients’ requests. The commonest analgesia was opioids (41.1%). Among non-users, the commonest reasons adduced were fear of respiratory distress (31.1%), cost (24.7%) and late presentation in labour (15.6%). Conclusion The routine prescription and utilization of obstetric analgesia by obstetricians in Nigeria is still low. Obstetricians are encouraged to step up its use to make childbirth a more fulfilling experience for parturients. PMID:24725280

Purpose: To evaluate the astigmatic correcting effect of paired opposite clear corneal incisions (OCCIs) on the steep axis in patients with residual astigmatism after laser in situ keratomileusis (LASIK) Materials and Methods: Thirty-one eyes of 24 patients with a mean age of 28.4 years ±2.46 (range, 19-36 years) were recruited for the study. Inclusion criteria included residual astigmatism of ≥1.5 diopter (D) after LASIK with inadequate residual stromal bed thickness that precluded ablation. The cohort was divided into two groups; group I (with astigmatism ranging from -1.5 D to -2.5 D) and group II (with astigmatism > -2.5 D). The steep axis was marked prior to surgery. Paired three-step self-sealing opposite clear corneal incisions were performed 1-mm anterior to the limbus on the steep axis with 3.2-mm keratome for group I and 4.1 mm for group II. Patients were examined 1 day, 1 week, 1 month, 3 months and 6 months, postoperatively. Visual acuity, refraction, keratometry, and corneal topography were evaluated preoperatively and postoperatively. Analysis of the difference between groups was performed with the Student t-test. P<0.05 was considered statistically significant. Results: The mean uncorrected visual acuity (UCVA) improved from 0.35±0.13 (range, 0.1-0.6) to 0.78±0.19 (range, 0.5-1) in group I and from 0.26±0.19 (range, 0.1-0.5) to 0.7±0.18 (range, 0.4-1) in group II. The increase in UCVA was statistically significant in both groups (P=0.001, both cases). The mean preoperative and postoperative keratometric astigmatism in group I was 2.0±0.48 D (range, 1.5-2.5 D) and 0.8±0.37 D (range, 0.1-1.4 D), respectively. The decrease in keratometric astigmatism was highly statistically significant in group II (P=0.001.). Mean surgically induced astigmatic reduction by vector analysis was 1.47±0.85 D and 2.21±0.97 D in groups I and II respectively. There were no incision-related complications. Conclusions: Paired OCCIs were predictable and effective in

The Green and Colorado Rivers comprise the main drainage system of the western slope of the Colorado Rockies and Colorado Plateau. In this region we compare river profiles and incision rates between these rivers to resolve controls on river evolution. Disequilibrium profiles in both rivers are evident by numerous knickpoints and convexities which we analyze in the context of a new compilation of incision rate data, including new isochron cosmogenic burial dates on early Quaternary terraces. The Lees Ferry knickpoint is interpreted to be an upstream-migrating knickpoint initiated by integration of the Colorado system through Grand Canyon about 6 Ma. An isochron cosmogenic burial date of 1.5 +/-0.13 Ma, on a 190-m-high strath terrace at Bullfrog Marina 169 km northeast of the knickpoint indicates an incision rate of 126 m/Ma. This date is 3x older than a cosmogenic surface date from the same terrace suggesting that high terraces dated by surface cosmogenic techniques are minimum dates. Available incision rates across the Lee’s Ferry knickpoint show rates of 150- 175 m/Ma below Lees Ferry and ca. 100- 130 m/Ma above the knickpoint (over 0.5 to 1 Ma) above. A burial date of 2.9 +0.7/-0.5 on a 110 m terrace that is 70 km farther upstream at Hite Crossing is problematic because the strath is lower, the date older, and the rate slower than nearby Bullfrog. The Hite data show significantly more scatter, and additional samples have been collected to clarify the age. Ca. 300-500 m/Ma rates within and above the knickpoint based on cosmogenic surface dates (with the caution these are maximum rates), suggest acceleration of incision rates in the late Quaternary due to a pulse of diffuse knickpoint propagation extending to several hundred km above Lees Ferry in the last few hundred-thousand years, as suggested by Cook et al. (2009). On the Green River, a new isochron cosmogenic burial date of 1.48 +/-0.12 Ma on an abandoned meander 60 m above the river in upper Desolation

Thermal and histological events resulting from soft tissue incision using CO2 lasers at 9.3 (mu) or 10.6 (mu) , fitted with a hollow wave guide or an articulated arm delivery system respectively, were investigated. In 9 fresh pigs' mandibles, standardized incisions 3 cm in length were made in the oral mucosa. Incisions were performed in the cw mode at 1 W, 4 W, and 12 W. Thermal events were measured in adjacent soft tissues using thermocouples. Incisions were dissected out, fixed, embedded in paraffin wax, sectioned and stained with Serius Red. The Students' t-test for paired data was used to compare zones of necrosis, zones of collagen damage and thermal events. No significant temperature rise was measured during irradiation at any timepoints or power settings (p < 0.05). Results were very similar for the two lasers with significantly different results obtained only at the 12 W setting (p < 0.05). Vertical incision depths and horizontal incision widths did not differ significantly (p < 0.0001) at 12 W and 4 W. Horizontal and vertical zones of necrosis did not differ significantly (p < 0.0001) either between the two lasers at 12 W and 4 W. Thus the thermal and histological events occurring during soft tissue incision were similar using these two lasers, despite the difference in wavelength and delivery system.

Optical coherence tomography (OCT) has revolutionized imaging of ocular structures and various disease conditions. Though it has been used in the clinic for some decades, the OCT has only recently found its way into the operating theater. Early attempts at intraoperative OCT, hand-held and microscope mounted, have already improved our understanding of the surgical pathology and the role it might play in surgical decision-making. The microscope-integrated OCT now allows seamless, high-resolution, real-time imaging of surgical maneuvers from the incision to wound closure. Visualization of instruments and intraoperative tissue manipulation are possible with this in vivo modality and, therefore, help improve the outcome of surgery. In this article, we describe the advantages it offers during various vitreoretinal procedures.

INTRODUCTION More aesthetically acceptable treatment options have been sought to minimise the morbidity associated with open surgery for gynaecomastia. This study investigated the use of a vacuum-assisted biopsy device (VABD) and liposuction to provide minimally invasive approach. PATIENTS AND METHODS Patients diagnosed with idiopathic benign gynaecomastia referred to the Breast Care Unit of Castle Hill Hospital between June 2002 and April 2007 and requesting surgical intervention underwent VABD excision and liposuction. All patients underwent thorough investigations to exclude any underlying cause for their gynaecomastia. The procedure was carried out by a single consultant surgeon with special interest in breast surgery. An 8-G mammotome probe was advanced through a 4-mm incision positioned in the corresponding anterior axillary line to excise the glandular disc. Liposuction was performed through the same incision. Incision wounds were closed with Steristrips. A pressure dressing was applied over wound by corset and an inflatable device. RESULTS Thirty-six male patients with grade I and II gynaecomastia were recruited (22 bilateral, 14 unilateral). Average age was 33.3 years (range, 16–88 years). All underwent mammotome excision and liposuction. There were no conversions to an open procedure. The average procedure time was 50.3 min (range, 30–80 min). One intra-operative complication was recorded. The minimum follow-up time was 2 months. Thirty-four patients reported excellent satisfaction, two patients had residual gynaecomastia and needed a re-do procedure. Three patients developed small haematomas that resolved spontaneously. CONCLUSION This novel, minimally invasive, surgical approach for gynaecomastia gives excellent results with minimal morbidity. PMID:20412670

Surgical treatment of buried penis.

The buried penis is a rare congenital entity, whose treatment is surgical. There are few publications concerning this matter. The authors report on their experience in 10 cases (1990-1995). In this abnormality, the tip of the glans does not project from the pubic or scrotal skin. It is due to: 1) an excessive development of the penile fascia which retracts the penis; 2) insufficient attachment of the penile skin at the base of the penis; 3) often excessive prepubic fat worsens the appearance of the abnormality but does not by itself totally explain it; 4) a tight phimosis is often present. Surgical treatment is necessary because this aspect tends to persist even after puberty. One cannot indeed count on the development at the age of puberty, neither on the diminution of the fat, nor on the simple cure of the phimosis. One must above all ban circumcision which causes the risk of eliminating the skin necessary for reconstruction. The surgical procedure will comprise: 1) a longitudinal dorsal incision extended circumferentially; 2) resection of the thickened fascia penis; 3) anchoring of the deep face of the dermis to the proximal part of the fascia penis at the base of the penis. This surgical procedure has always brought a significant improvement to the appearance of the penis.

The diagnosis of a complete acromioclavicular separation (Tossy III) is a indication for a surgical repair. Many and different methods are reported in history. 33 patients with a fresh, complete acromioclavicular separation are treated at the BG-Unfallklinik Tübingen from 1. 1. 1970--31. 12. 1978 by suturing the ligaments, inserting pins across the joint and tension-bending. With this method good results have been achieved, possible intra- and postoperative complications are reported. The incision along the clavicula gives quite often scar problems. Therefore we now use an arched incision across the AC-joint.

In vitro research and development laboratory, Alcon Research, Irvine, California, USA. Phacoemulsification was performed in eye-bank cadaver eyes and the following parameters evaluated: incision, duty cycle, ultrasound (US) power, aspiration flow rate (AFR), vacuum, pulse, bottle height and balanced salt solution temperature, and tip design/size. Each parameter was varied while the others remained constant. The resulting temperature of the incision and US tip was measured using a thermal camera. Major contributors to elevated incision temperature included incision size, US power, duty cycle, AFR, vacuum setting, tip design, and presence of an ophthalmic viscosurgical device (OVD). Minor contributors included pulse frequency, bottle height, and temperature of the infusate. Microincision lens removal can be performed at safe temperatures with the knowledgeable selection of surgeon-controlled parameters.

To summarize the social, economic, emotional, and psychological consequences incurred by women with obstetric fistula; present the results of a meta-analysis for 2 major consequences, divorce/separation and perinatal loss; and report on improvements in health and self-esteem and on the possibility of social reintegration following successful fistula repair. We conducted a review of the literature published between 1985 and 2005 on fistula in developing countries. We then performed a meta-analysis for 2 of the major consequences of having a fistula, divorce/separation and perinatal child loss. Studies suggest that surgical treatment usually closes the fistula and improves the physical and mental health of affected women. With additional social support and counseling, women may be able to successfully reintegrate socially following fistula repair.

The economic impact of a family physician practicing family medicine in rural Alabama is $1,000,000 a year in economic benefit to the community. The economic benefit of those rural family physicians practicing obstetrics has not been studied. This study was designed to determine whether there was any added economic benefit of rural family physicians practicing obstetrics in rural, underserved Alabama. The Alabama Family Practice Rural Health Board has funded the University of Alabama Family Medicine Obstetrics Fellowship since its beginning in 1986. Family medicine obstetrics fellowship graduates who practice obstetrics in rural, underserved areas were sent questionnaires and asked to participate in the study. The questions included the most common types and average annual numbers of obstetrics/gynecological procedures they performed. Ten physicians, or 77% of the graduates asked to participate in the study, returned the questionnaire. Fourteen common obstetrics/gynecological procedures performed by the graduates were identified. A mean of 115 deliveries were performed. The full-time equivalent reduction in family medicine time to practice obstetrics was 20%. A family physician practicing obstetrics in a rural area adds an additional $488,560 in economic benefit to the community in addition to the $1,000,000 from practicing family medicine, producing a total annual benefit of $1,488,560. The investment of $616,385 from the Alabama Family Practice Rural Health Board resulted in a $399 benefit to the community for every dollar invested. The cumulative effect of fellowship graduates practicing both family medicine and obstetrics in rural, underserved areas over the 26 years studied was $246,047,120. © Copyright 2014 by the American Board of Family Medicine.

To analyze the changes in incision sizes after implantation of a toric intraocular lens (IOL) using 2 methods. Department of Ophthalmology, Clínica Universidad de Navarra, Pamplona, Spain. Prospective case series. Coaxial phacoemulsification and IOL implantation through a 2.2 mm clear corneal incision using a cartridge injector were performed. Wound-assisted or cartridge-insertion techniques were used to implant the IOLs. The results were analyzed according to IOL spherical and cylindrical powers. Corneal hysteresis (CH) and the corneal resistance factor (CRF) were measured and evaluated based on the changes in incision size. Incision size increased in 30 (41.7%) of 72 eyes in the wound-assisted group and 71 (98.6%) of 72 eyes in the cartridge-insertion group. The mean incision size after IOL implantation was 2.27 mm ± 0.06 (SD) and 2.37 ± 0.05 mm, respectively (P<.01). The final incision size and IOL spherical power in the wound-assisted technique group (P=.02) and the cartridge-insertion technique group (P=.03) were correlated significantly; IOL toricity was not (P=.19 and P=.28, respectively). The CH and CRF values were not correlated with the final incision size. The final incision size and the changes in incision size after IOL implantation were greater with the cartridge-insertion technique than with the wound-assisted technique. The increase was related to IOL spherical power in both groups but not to IOL toricity. Corneal biomechanical properties were not correlated with the final incision size.

To test a novel hydrogel sealant to secure sutureless sclerotomies under variable intraocular pressure conditions. In cadaver eyes, 23- and 20-gauge (G) sclerotomies were constructed. Sixteen 23-G beveled sclerotomies were constructed in 4 eyes: 8 of the incisions were treated with hydrogel sealant, while 8 were left bare. All sclerotomies were monitored for leaks while the intraocular pressure was elevated. The pressure on incision leakage was recorded as the leak pressure (maximum tested = 140 mm Hg). Additionally, sixteen 20-G sclerotomies were constructed in 4 other eyes: 8 of the incisions were treated with hydrogel sealant, while 8 were sutured. These incisions were similarly pressure tested. Among the 23-G incisions, hydrogel sealant application to the incisions significantly increased the leak pressure relative to bare incisions: mean (SE), 131.8 (8.2) vs 39.5 (5.2) mm Hg, respectively (P < .001). Only 1 of the 8 sealant-treated 23-G incisions leaked below 140 mm Hg, compared with all of the 8 bare incisions. Among the 20-G incisions, there was no difference in leak pressure among sealant-treated and sutured incisions: mean (SE), 140.0 (0.0) vs 136.3 (3.8) mm Hg, respectively (P = .35). None of the 8 sealant-treated 20-G incisions leaked below 140 mm Hg, compared with 1 of the 8 sutured incisions. Hydrogel sealant significantly increased the leak pressure among 23-G incisions relative to 23-G bare incisions and was equivalent to suturing among 20-G incisions. Hydrogel sealants effectively close vitrectomy incisions and may decrease the incidence of postoperative endophthalmitis and hypotony.

Late Cenozoic Colorado River Incision and Implications for Neogene Uplift of the Colorado Rockies

Basalt flows and volcanic ashes serve as a datum for calculating post-10 Ma river incision rates in western Colorado. The main picture that emerges from the data is one of regional variability of incision rates, which we hypothesize to reflect differential uplift of the Colorado Rockies during the Neogene. Maximum rates (90-180 m/Ma) and magnitudes (750-1500 m) of river incision are recorded between Grand Mesa and Glenwood Canyon, and in the Flat Tops. Minimum rates (<30 m/Ma) and magnitudes (<250 m) of river incision are associated post-Laramide normal faults within the Browns Park-Sand Wash basin in northwestern Colorado and in Middle Park of north-central Colorado. Differential uplift of the Colorado Rockies during the late Cenozoic can be inferred by comparing incision rates and magnitudes at locations upstream and downstream of knickzones. Along the Colorado River, post-10 Ma incision rates and magnitudes incision remain fairly constant (rates >100 m/Ma; magnitudes >1000 m) from Grand Mesa upstream to Gore Canyon, and then decrease markedly in Middle Park (rates <10 m/Ma; magnitudes <100 m) across the Gore Canyon knickzone. Normal-faulting of ca. 10 Ma deposits in Middle Park shows that incision rate variations partly reflect late Cenozoic faulting. Along the Yampa River, post-10 Ma incision rates and magnitudes are low (rates 15-27 m/Ma; magnitudes < 230 m) immediately upstream of Yampa Canyon, and then increase significantly (rates 96-132 m/Ma; magnitudes ~1250 m) upstream near the headwaters. We interpret this upstream increase in river incision rate and magnitude to reflect Neogene uplift of the Yampa River headwaters relative to its lower reaches. Lastly, differential late Cenozoic uplift of the Colorado Rockies is suggested by differences in the timing of regional exhumation and river incision within different drainage basins. Colorado River incision and regional exhumation occurred between 9.8 and 7.8 Ma. In contrast, Yampa River incision began between

Gynecomastia refers to a benign enlargement of the male breast. This article describes the authors' method of using power-assisted liposuction and gland removal through a subareolar incision for thin patients. Power-assisted liposuction is performed for removal of fatty breast tissue in the chest area to allow skin retraction. The subareolar incision is used to remove glandular tissue from a male subject considered to be within a normal weight range but who has bilateral grade 1 or 2 gynecomastia. Gynecomastia correction was successfully performed for all the patients. The average volume of aspirated fat breast was 100-200 ml on each side. Each breast had 5-80 g of breast tissue removed. At the 3-month, 6-month, and 1-year follow-up assessments, all the treated patients were satisfied with their aesthetic results. Liposuction has the advantages of reducing the fat tissue where necessary to allow skin retraction and of reducing the traces left by surgery. The combination of surgical excision and power-assisted lipoplasty also is a valid choice for the treatment of thin patients.

Chronic post-surgical pain (CPSP) remains a major clinical problem and is often refractory to current treatments. New analgesic medications and strategies for pain relief are needed. Hepatocyte growth factor (HGF) is known to be a multi-functional growth factor and regulates various biological activities. We investigated the analgesic effect and underlying mechanism of plasmid pUDK-HGF encoding human HGF gene on CPSP induced by skin/muscle incision and retraction (SMIR) in rats. The possible changes of inflammatory factors, glial cell activation and pain sensitivity after pUDK-HGF administration were investigated by ELISA, western blot and Von Frey tests, respectively. In behavioural assays, we found that a single intramuscular or intrathecal injection of pUDK-HGF significantly attenuated mechanical hypersensitivity to von Frey stimulation of plantar ipsilateral hind paw after SMIR. Intramuscular injection of pUDK-HGF promoted blood flow and proliferation of satellite cells and inhibited inflammatory cells recruitment, collagen accumulation and expression of pronociceptive factors. Intrathecal injection of pUDK-HGF inhibited activation of spinal glial cells and production of inflammatory mediators induced by SMIR. pUDK-HGF has a strong analgesic potency and efficacy in CPSP induced by SMIR in rats. This study highlights a new strategy for the treatment of CPSP. The CPSP occurs following various surgical procedures and remains a major clinical problem due to the lack of study on the mechanisms of CPSP. Our findings provide the first evidence that pUDK-HGF attenuates SMIR-induced pain behaviuors through peripheral or central mechanisms. The peripheral analgesic effect of pUDK-HGF is associated with promoting tissue repair and inhibiting inflammatory response; furthermore, pUDK-HGF inhibits activation of spinal glial cells and overexpression of inflammatory mediators in spinal cord. Therefore, naked pUDK-HGF may be a potential therapeutic strategy for treatment of

To improve staff perception of the quality of the patient admission process from obstetric triage to the labor and delivery unit through standardization. Preassessment and postassessment online surveys. A 13-bed labor and delivery unit in a quaternary care, Magnet Recognition Program, academic medical center in Pennsylvania. Preintervention (n = 100), postintervention (n = 52), and 6-month follow-up survey respondents (n = 75) represented secretaries, registered nurses, surgical technicians, certified nurse-midwives, nurse practitioners, maternal-fetal medicine fellows, anesthesiologists, and obstetric and family medicine attending and resident physicians from triage and labor and delivery units. We educated staff and implemented interventions, an admission huddle and safety time-out whiteboard, to standardize the admission process. Participants were evaluated with the use of preintervention, postintervention, and 6-month follow-up surveys about their perceptions regarding the admission process. Data tracked through the electronic medical record were used to determine compliance with the admission huddle and whiteboards. A 77% reduction (decrease of 49%) occurred in the perception of incomplete patient admission processes from baseline to 6-month follow-up after the intervention. Postintervention and 6-month follow-up survey results indicated that 100% of respondents responded strongly agree/agree/neutral that the new admission process improved communication surrounding care for patients. Data in the electronic medical record indicated that compliance with use of admission huddles and whiteboards increased from 50% to 80% by 6 months. The new patient admission process, including a huddle and safety time-out board, improved staff perception of the quality of admission from obstetric triage to the labor and delivery unit.

Tran, Kim; Zajkowska, Marta; Lam, Vincent; Hawthorne, Wayne

2014-01-01

Introduction: Despite an exponential rise in laparoscopic surgery for inguinal herniorrhaphy, overall recurrence rates have remained unchanged. Therefore, an increasing number of patients present with recurrent hernias after having failed anterior and laparoscopic repairs. This study reports our experience with single-incision laparoscopic (SIL) intraperitoneal onlay mesh (IPOM) repair for these hernias. Materials and methods: All patients referred with multiply recurrent inguinal hernias underwent SIL-IPOM from November 1 2009 to October 30 2013. A 2.5-cm infraumbilical incision was made and a SIL surgical port was placed intraperitoneally. Modified dissection techniques, namely, “chopsticks” and “inline” dissection, 5.5 mm/52 cm/30° angled laparoscope and conventional straight dissecting instruments were used. The peritoneum was incised above the symphysis pubis and dissection continued laterally and proximally raising an inferior flap, below a previous extraperitoneal mesh, while reducing any direct/indirect/femoral/cord lipoma before placement of antiadhesive mesh that was fixed into the pubic ramus as well as superiorly with nonabsorbable tacks before fixing its inferior border with fibrin sealant. The inferior peritoneal flap was then tacked back onto the mesh. Results: There were 9 male patients who underwent SIL-IPOM. Mean age was 55 years old and mean body mass index was 26.8 kg/m2. Mean mesh size was 275 cm2. Mean operation time was 125 minutes with hospital stay of 1 day and umbilical scar length of 21 mm at 4 weeks' follow-up. There were no intraoperative/postoperative complications, port-site hernias, chronic groin pain, or recurrence with mean follow-up of 20 months. Conclusions: Multiply recurrent inguinal hernias after failed conventional anterior and laparoscopic repairs can be treated safely and efficiently with SIL-IPOM. PMID:25392643

Influence of orographic precipitation on the incision within a mountain-piedmont system

2017-04-01

The geomorphological evolution of a mountain-piedmont system depends both on tectonics and climate, as well as on couplings between the mountain and its piedmont. Although the interactions between climate and tectonics are a fundamental point for understanding the landscape evolution, the erosion of a mountain range and the sediment deposition at the mountain front, or piedmont, have been poorly studied as a coupled system. Here we focus on the conditions driving an incision within such a system. Classically, it is thought that incision results from a change in climate or uplift rates. However, it is not clear which are the specific conditions that favor the occurrence of river incision in the piedmont. In particular, studies have shown that the presence of a piedmont can modify the incision patterns, and even drive autogenic incision, without any change in external forcings. This is a crucial issue in order to interpret natural incisions in terms of uplift or climatic modifications. Such a problem is further complicated by the modification of local precipitations and temperatures during uplift, because the progressive effect of climate change may superimpose to uplift. In this work we explore the hypothesis that a mountain-piedmont coupled system may develop incision in its piedmont as a result of enhanced orographic precipitations during surface uplift. We use a landscape evolution model, Cidre, in order to explore the response of a mountain-piemont system in which the mountain is continuously uplifted but in which precipitation rates depend on elevations. Thus precipitation amounts change during the mountain uplift. We test different peaks and amplitudes of the orographic precipitation pattern, maintaining the other conditions constant. Preliminary results show that elevation-dependent precipitations drive temporary but pronounced incisions of the main rivers within the piedmont, contrary to experiments without orographic precipitations.

The present paper describes the rationale behind the surgical technique and the clinical results of the iso-anatomical, single bundle bone patellar-tendon bone anterior cruciate ligament (ACL) reconstruction. Using a second incision on the distal lateral femur an outside-in femoral tunnel is drilled. Guided by a special aiming device it is possible to place the femoral tunnel in the centre of the ACL footprint in every single case. Since every crucial step of the procedure is under visual control, the technique is safe and reliable, which is mirrored by good clinical results.

Cochlear implantation with Pulsar Med El: a novel small incision technique.

Cuda, D

2009-04-01

Although still widely implanted, Pulsar Med-El is rarely considered for small incision approach. Overall, 30 teen-age and adult patients were operated upon with a novel small incision (4-5 cm). Full insertion of the electrode array was achieved in all cases. No major intra-operative complications occurred. At follow-up, no flap-related complications and no migration of the receiver-stimulator were observed in the "device suture" (14 patients) or "no device suture" groups (16 patients). All patients are full-time users of the device. In conclusion, a small incision for the Pulsar Med-El cochlear implant is feasible, safe and reproducible. Ligature fixation of the device is not critical with this operation. Also with this device, in adult and teen-age patients, it is, therefore, possible to retain several typical advantages of small incision approaches.

Abstract Background: Surgical site infections (SSI) account for a major proportion of hospital-acquired infections. They are associated with longer hospital stay, readmissions, increased costs, mortality, and morbidity. Reducing SSI is a goal of the Surgical Care Improvement Project and identifying interventions that reduce SSI effectively is of interest. In a single-blinded randomized controlled trial (RCT) we evaluated the effect of localized warming applied to surgical incisions on SSI development and selected cellular (immune, endothelial) and tissue responses (oxygenation, collagen). Methods: After Institutional Review Board approval and consent, patients having open bariatric, colon, or gynecologic-oncologic related operations were enrolled and randomly assigned to local incision warming (6 post-operative treatments) or non-warming. A prototype surgical bandage was used for all patients. The study protocol included intra-operative warming to maintain core temperature ≥36°C and administration of 0.80 FIO2. Patients were followed for 6 wks for the primary outcome of SSI determined by U.S. Centers for Disease Control (CDC) criteria and ASEPSIS scores (additional treatment; presence of serous discharge, erythema, purulent exudate, and separation of the deep tissues; isolation of bacteria; and duration of inpatient stay). Tissue oxygen (PscO2) and samples for cellular analyses were obtained using subcutaneous polytetrafluoroethylene (ePTFE) tubes and oxygen micro-electrodes implanted adjacent to the incision. Cellular and tissue ePTFE samples were evaluated using flow cytometry, immunohistochemistry, and Sircol™ collagen assay (Biocolor Ltd., Carrickfergus, United Kingdom). Results: One hundred forty-six patients participated (n=73 per group). Study groups were similar on demographic parameters and for intra-operative management factors. The CDC defined rate of SSI was 18%; occurrence of SSI between groups did not differ (p=0.27). At 2 wks, warmed

In patients with major comorbidities undergoing complex cardiothoracic surgery, incision management is critical. This retrospective review evaluated negative pressure over closed sternal incisions in cardiac patients with multiple comorbidities within 30 days post-median sternotomy. Records of post-sternotomy patients treated with Prevena™ Incision Management System (KCI, an Acelity company, San Antonio, TX), a closed incision negative pressure therapy (ciNPT), were reviewed from September 2010 through September 2014. Data collected included demographics, major comorbidities, types of surgery, relevant medical history, incision length, therapy duration, time to follow-up, and incision complications. Descriptive statistics were computed for continuous variables, frequency, and percentages for categorical variables. Twenty-seven patients were treated with ciNPT between September 2010 and September 2014. The mean patient age was 62.5 (SD 7.9), and the mean body mass index (BMI) was 38.5 (SD 4.4) kg/m(2). Risk factors included obesity (BMI ≥ 30 kg/m(2), 27/27; 100%), diabetes (25/27; 92.6%), hypertension (16/27; 59.3%), and 20/27 patients (74%) had ≥ 5 comorbidities. Mean ciNPT duration was 5.6 (SD 0.9) days. Within 30 days post-surgery, 21/27 (77.8%) patients had intact incisions with good reapproximation. Two patients experienced minor dehiscences; four cases of superficial cellulitis were treated and resolved. One patient with a dehiscence was readmitted for intravenous antibiotics and five patients were managed successfully with antibiotics as outpatients. All patients had intact incisions with good skin approximation at final follow-up. In this retrospective study of post-sternotomy patients at high risk of developing complications, ciNPT over closed sternal incisions resulted in favorable outcomes within 30 days of surgery.

Obstetric violence involves a violation of reproductive rights of women during pregnancy, childbirth and postpartum. It has been associated with lack of empathy and emotional discomfort of physicians. To identify the perceptions of obstetric violence and to determine the possible relationship with burnout syndrome. We evaluated 29 physicians whose scope of work relates to obstetrics and gynecology. The evaluation instruments were: a) questionnaire on professional perception that collects demographic information, situations of perceived obstetric violence, major concerns of physicians in their professional work, and includes an scale about level of job satisfaction, b) the Maslach Burnout inventory, and c) Jefferson Scale of Physician Empathy. The most prevalent obstetric violence situations perceived were: medical malpractice and harmful practices (10/29), discrimination (10/29), rude treatment and verbal attacks (11/29). Seventeen participants reported lack of information on obstetric violence and not have tools to cope with this problem. Regarding the burnout syndrome, it was associated with several items of the scale of empathy and with the scale of job satisfaction. This study shows the importance of providing knowledge and tools to deal with obstetric violence and stress management to prevent such situations on medical practices.

Laser tissue soldering is a method of repairing incisions. It involves the application of a biological solder to the approximated edges of the incision and heating it with a laser beam. A pilot clinical study was carried out on 10 patients who underwent laparoscopic cholecystectomy. Of the four abdominal incisions in each patient, two were sutured and two were laser soldered. Cicatrization, esthetical appearance, degree of pain, and pruritus in the incisions were examined on postoperative days 1, 7, and 30. The soldered wounds were watertight and healed well, with no discharge from these wounds or infection. The total closure time was equal in both methods, but the net soldering time was much shorter than suturing. There was no difference between the two types of wound closure with respect to the pain and pruritus on a follow-up of one month. Esthetically, the soldered incisions were estimated as good as the sutured ones. The present study confirmed that temperature-controlled laser soldering of human skin incisions is clinically feasible, and the results obtained were at least equivalent to those of standard suturing.

This study looks at a trilogy of women's health issues including severe pelvic organ prolapse, unrepaired 4th degree obstetric tears and obstetric fistula, all of which can cause significant suffering in the lives of women and their families. Women undergoing surgery for severe pelvic organ prolapse, unrepaired 4th degree obstetric tears and obstetric fistulae, were interviewed to assess their perceptions of what caused their condition, subsequent impact on their social situation and sexual activity, and whether they had sought treatment previously. One hundred fifty women participated in the survey, including 69 undergoing surgery for genito-urinary fistula, 25 with faecal incontinence only (including 24 women with unrepaired 4th degree obstetric tears and 1 woman with an isolated rectovaginal fistula), and 56 women with severe pelvic organ prolapse. All groups of women were exposed to abandonment by their families with 42 % of women with genito-urinary fistula, 21 % with unrepaired 4th degree obstetric tear, and 25 % of women with severe pelvic organ prolapse rejected by their husbands. Most of the women had actively sought treatment for their condition with no success due to unavailability of treatment or misinformation. This study confirms the social stigma associated with obstetric fistula, however also highlights the social stigma faced by women suffering with severe pelvic organ prolapse and unrepaired 4th degree obstetric tears in western Uganda. There is an urgent need for education and training in obstetric management and pelvic organ prolapse management in such areas of limited resources.

D2-like receptors in the descending dopaminergic pathway are not involved in the decreased postoperative nociceptive threshold induced by plantar incision in adult rats.

Approximately half of all patients who undergo surgery develop postoperative pain, the mechanisms of which are not well understood by anesthesiologists. D2-like receptors in the descending dopaminergic pathway play an important role in regulation of pain transmission in the spinal cord. Impairment of inhibitory neurons in the spinal cord is suggested as part of the mechanism for neuropathic pain, which is one component of postoperative pain. The purpose of this study was to investigate whether impairment of D2-like receptors in the descending dopaminergic pathway in the spinal cord is involved in the decreased postoperative nociceptive threshold in rats. Male Sprague-Dawley rats (250-300 g) were anesthetized with sevoflurane and an intrathecal (IT) catheter was implanted. Six days later, a plantar incision was made. On the following day, saline, a D2-like receptor agonist (quinpirole), or a D2-like receptor antagonist (sulpiride) was administered intrathecally. Thermal and mechanical nociceptive responses were assessed by exposure to infrared radiant heat and the von Frey filament test before and after plantar incision. Plantar incision decreased both thermal latency and the mechanical nociceptive threshold. IT administration of quinpirole inhibited the nociceptive responses induced by plantar incision, but sulpiride had no effect. A D2-like receptor agonist had antinociceptive effects on the hypersensitivity response triggered by a surgical incision, but a D2-like receptor antagonist had no effect on this response. These results suggest that impairment and/or modification of D2-like receptors in the descending dopaminergic pathway in the spinal cord is not involved in the postoperative decrease in nociceptive threshold.

Methods We examined 26 eyes of 26 patients undergoing FLEx and 26 eyes of 26 patients undergoing SMILE to correct myopic astigmatism (manifest astigmatism of 1 diopter (D) or more). Visual acuity, cylindrical refraction, the predictability of the astigmatic correction, and the astigmatic vector components using Alpin’s method, were compared between the two groups 3 months postoperatively. Results We found no statistically significant difference in manifest cylindrical refraction (p=0.74) or in the percentage of eyes within ± 0.50 D of their refraction (p=0.47) after the two surgical procedures. Moreover, no statistically significant difference was detected between the groups in astigmatic vector components, namely, surgically induced astigmatism (0.80), target induced astigmatism (p=0.87), astigmatic correction index (p=0.77), angle of error (p=0.24), difference vector (p=0.76), index of success (p=0.91), flattening effect (p=0.79), and flattening index (p=0.84). Conclusions Both FLEx and SMILE procedures are essentially equivalent in correcting myopic astigmatism using vector analysis, suggesting that the lifting or non-lifting of the flap does not significantly affect astigmatic outcomes after these surgical procedures.

To describe the challenges associated with the development and assessment of an obstetric emergency team simulation program. The goal was to develop a hybrid, in-situ and high fidelity obstetric emergency team simulation program that incorporated weekly simulation sessions on the labor and delivery unit, and quarterly, education protected sessions in the simulation center. All simulation sessions were video-recorded and reviewed. Labor and delivery unit and simulation center. Medical staff covering labor and delivery, anesthesiology and obstetric residents and obstetric nurses. Assessments included an on-line knowledge multiple-choice questionnaire about the simulation scenarios. This was completed prior to the initial in-situ simulation session and repeated 3 months later, the Clinical Teamwork Scale with inter-rater reliability, participant confidence surveys and subjective participant satisfaction. A web-based curriculum comprising modules on communication skills, team challenges, and team obstetric emergency scenarios was also developed. Over 4 months, only 6 labor and delivery unit in-situ sessions out of a possible 14 sessions were carried out. Four high-fidelity sessions were performed in 2 quarterly education protected meetings in the simulation center. Information technology difficulties led to the completion of only 18 pre/post web-based multiple-choice questionnaires. These test results showed no significant improvement in raw score performance from pre-test to post-test (P=.27). During Clinical Teamwork Scale live and video assessment, trained raters and program faculty were in agreement only 31% and 28% of the time, respectively (Kendall's W=.31, P<.001 and W=.28, P<.001). Participant confidence surveys overall revealed confidence significantly increased (P<.05), from pre-scenario briefing to after post-scenario debriefing. Program feedback indicates a high level of participant satisfaction and improved confidence yet further program refinement is

Single-incision laparoscopic colectomy is technically limited because of such factors as instrument crowding, in-line viewing, and insufficient countertraction. In particular, it is technically difficult to cut the distal rectum from the umbilicus using an articulating linear stapler in single-incision laparoscopic anterior resection. After treating the mesorectum, the 5-mm trocar is replaced with a 12-mm trocar. The cartridge of the curved stapler is mounted while the shaft of the stapler is inserted into the 12-mm port extracorporeally. The curved stapler is inserted through the umbilical incision with the cartridge. A multichannel port is then mounted, and the abdominal cavity is reinsufflated. The curved stapler can then be operated intracorporeally. This procedure facilitates the vertical dissection of the rectum from the umbilicus. A total of 27 consecutive patients were analyzed in this study. All the procedures were safely performed without any complications. The median distance from the peritoneal reflection to the transection point of the distal bowel in single-incision laparoscopic anterior resection was 5.0 cm (range, -2.0 to 15.0). One stapler firing was required to achieve distal bowel division in 26 patients (96.3 %), whereas 2 firings were required in 1 patient (3.7 %). The median distal margin was 7.0 cm (range, 3.0-13.0). The time from the insertion of the stapler to transection was 180 seconds (range, 100-420). There were no cases of anastomotic leakage. In single-incision laparoscopic anterior resection, it is feasible to perform rectal transection from the umbilicus by using a curved stapler. This technique may allow for the omission of 1 trocar from the operation.

The cross-sectional study has been based on the implementation of the Obstetric Appropriateness Evaluation Protocol (OAEP) in seven hospitals to determine inappropriate hospital admissions and days of stay. The outcomes were: inappropriateness of admission and "percentage of inappropriateness" for one hospitalization. A total number of 2196 clinical records were reviewed. The mean percentage of inappropriateness for hospitalization was 22%. The percentage of inappropriateness for the first 10 d of hospitalization peaked in correspondence of the fourth (42%). The logistic regression model on inappropriated admission reported that emergency admission was a protective factor (OR = 0.4) and to be hospitalized in wards with ≥30 beds risk factor (OR = 5.12). The second linear model on "percentage of inappropriateness" showed that inappropriated admission and wards with ≥30 beds increased the percentage (p < 0.001); whereas the admission in Teaching Hospitals was inversely associated (p < 0.001). The present study suggests that the percentage of inappropriate admission depends especially on the inappropriate admission and the large number of beds in obstetric wards. This probably indicates that management of big hospitals, which is very complex, needs improving the processes of support and coordination of health professionals. The OAEP tool seems to be an useful instrument for the decision-makers to monitor and manage the obstetric wards.

Emergency preparedness in obstetrics.

During and after disasters, focus is directed toward meeting the immediate needs of the general population. As a result, the routine health care and the special needs of some vulnerable populations such as pregnant and postpartum women may be overlooked within a resource-limited setting. In the event of hazards such as natural disasters, manmade disasters, and terrorism, knowledge of emergency preparedness strategies is imperative for the pregnant woman and her family, obstetric providers, and hospitals. Individualized plans for the pregnant woman and her family should include knowledge of shelter in place, birth at home, and evacuation. Obstetric providers need to have a personal disaster plan in place that accounts for work responsibilities in case of an emergency and business continuity strategies to continue to provide care to their communities. Hospitals should have a comprehensive emergency preparedness program utilizing an "all hazards" approach to meet the needs of pregnant and postpartum women and other vulnerable populations during disasters. With lessons learned in recent tragedies such as Hurricane Katrina in mind, we hope this review will stimulate emergency preparedness discussions and actions among obstetric providers and attenuate adverse outcomes related to catastrophes in the future.

The objective of this study is to gain insight into the nature of obstetric fistulae in Africa through patient perspectives. At l'Hôpital Saint Jean de Dieu in Tanguieta, Benin, 37 fistula patients underwent structured interviews about fistula cause, obstacles to medical care, prevention, and reintegration by 2 physicians via interpreters. The majority of participants (43%) thought their fistulae were a result of trauma from the operative delivery. Lack of financial resources (49%) was the most commonly reported obstacle to care, and prenatal care (38%) was most frequently reported as an intervention that may prevent obstetric fistulae. The majority (49%) of the participants requested no further reintegration assistance aside from surgery. Accessible emergency obstetric care is necessary to decrease the burden of obstetric fistulae in Africa. This may be accomplished through increased and improved health care facilities and education of providers and patients.

Community-based surveillance methods to monitor epidemiological progress in surgery have not yet been employed for surgical capacity building. The aim of this study was to create and assess the validity of a questionnaire that collected data for untreated surgically correctable diseases throughout Burera District, northern Rwanda, to accurately plan for surgical services. A structured interview to assess for the presence or absence of ten index surgically treatable conditions (breast mass, cleft lip/palate, club foot, hernia or hydrocele [adult and paediatric]), hydrocephalus, hypospadias, injuries or wounds, neck mass, undescended testes, and vaginal fistula) was created. The interview was built based on previously validated questionnaires, forward and back translated into the local language and underwent focus group augmentation and pilot testing. In March and May, 2012, data collectors conducted the structured interviews with a household representative in 30 villages throughout Burera District, selected using a two-stage cluster sampling design. Rwandan physicians revisited the surveyed households to perform physical examinations on all household members, used as the gold standard to validate the structured interview. Ethical approval was obtained from Boston Children's Hospital (Boston, MA, USA) and the Rwandan National Ethics Committee (Kigali, Rwanda). Informed consent was obtained from all households. 2990 individuals were surveyed, a 97% response rate. 2094 (70%) individuals were available for physical examination. The calculated overall sensitivity of the structured interview tool was 44·5% (95% CI 38·9-50·2) and the specificity was 97·7% (96·9-98·3%; appendix). The positive predictive value was 70% (95% CI 60·5-73·5), whereas the negative predictive value was 91·3% (90·0-92·5). The conditions with the highest sensitivity and specificity, respectively, were hydrocephalus (100% and 100%), clubfoot (100% and 99·8%), injuries or wounds (54·7% and

A total of 142 women with severe acute renal failure (ARF) resulting from obstetric causes was treated by dialysis at a single centre from 1956 to 1987. One-year survival was 78.6%, which compares favourably with other causes of ARF. Abortion, haemorrhage and preclampsia comprised 95% of cases, with survival being best (82.9%) with abortion. Survival was adversely affected by increasing age. Acute cortical necrosis (12.7% of patients) carried 100% mortality after 6 years. Follow-up of survivors showed normal renal function up to 31 years following ARF; 25-year patient survival was 71.6%. Improvements in obstetric care and the disappearance of illegal abortions have resulted in a dramatic decline in the incidence of obstetric ARF.

Lymphatic vessel diameter and lymph flow are important for accurate anastomosis and effective lymph-to-venous flow in lymphaticovenular anastomosis. The authors developed a reliable method, the superioredge-of-the-knee incision method, for detecting and making the best use of high-flow lymphatic vessels in the distal medial thigh between the deep and superficial fascia, where movement of the knee, combined with compression between these fascial layers, theoretically results in upward propulsion of lymphatic fluid. Intraoperative detection of large lymphatic vessels and of venous reflux and postoperative lymphedematous volume reduction were compared between 15 patients in whom lymphaticovenular anastomoses with the superior-edge-of-the-knee incision method were undergone and 15 in whom conventional lymphaticovenular anastomoses were undergone. Lymphaticovenular anastomosis at the thigh yielded 30 anastomoses in the superior-edge-of-the-knee incision group and 32 anastomoses in the non-superior-edge-of-the-knee incision group. Large lymphatic vessels were more frequently found in the superior-edge-of-the-knee incision group than in the non-superior-edge-of-the-knee incision group (60.0 percent versus 18.8 percent; p = 0.002). Venous reflux occurred less frequently in the superior-edge-of-the-knee incision group than in the non-superior-edge-of-the-knee incision group (10.0 percent versus 65.6 percent; p < 0.001). Reduction of the lower extremity lymphedema index was significantly greater in the superior-edge-of-the-knee incision group than in the non-superior-edge-of-the-knee incision group (24.427 ± 12.400 versus 0.032 ± 20.535; p < 0.001). The superior-edge-of-the-knee incision method facilitates detection and use of large, high-flow lymphatic vessels in the distal medial thigh, both of which are important for optimum therapeutic effects in patients with lower extremity lymphedema.

An unsolved problem of laparoscopic cholecystectomy is the optimal method of removing the gallbladder with thick walls and a large stone burden. Proposed solutions include fascial dilatation, stone crushing, and ultrasonic, high-speed rotary, or laser lithotripsy. Our observation was that extension of the fascial incision to remove the impacted gallbladder was time efficient and did not increase postoperative pain. We reviewed the narcotic requirements of 107 consecutive patients undergoing laparoscopic cholecystectomy. Fifty-two patients required extension of the umbilical incision, and 55 patients did not have their fascial incision enlarged. Parenteral meperidine use was 39.5 +/- 63.6 mg in the patients requiring fascial incision extension and 66.3 +/- 79.2 mg in those not requiring fascial incision extension (mean +/- standard deviation). Oral narcotic requirements were 1.1 +/- 1.5 doses vs 1.3 +/- 1.7 doses in patients with and without incision extension, respectively. The wide range of narcotic use in both groups makes these apparent differences not statistically significant. We conclude that protracted attempts at stone crushing or expensive stone fragmentation devices are unnecessary for the extraction of a difficult gallbladder during laparoscopic cholecystectomy.

Analyze international reports related to training in obstetrics and present guidelines to help leading educational institutions to develop curriculum guidelines for the teaching of obstetrics and advanced nursing practice in this specialty. A narrative review was conducted of documents from the World Health Organization and the International Confederation of Midwives. The search used the descriptors midwifery and education. All official reports that guide midwife education policies, published from 2009 to 2015 in English and Spanish, and available online, were included. Reports that did not specifically refer to training were excluded. Five reports were selected. Analysis and synthesis of their respective objectives and contents were based on three themes: requirements for professional qualification, continuing education, and guidelines for skilled training in obstetrics, taking into account accepted core competencies for this specialty. Analysis of reports related to training in obstetrics identified that key tasks are being implemented for both educators and midwives. The reports represent a solid basis to develop educational policies that can contribute to universal access and coverage in health and to reducing maternal and neonatal mortality, and potentially can be used to guide international policies.
