Abstract
BACKGROUND The most commonly performed bariatric procedures are laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (LSG). Impact of learning curves on operative outcome has been well shown, but the necessary learning curves have not been clearly defined. This study provides a systematic review of the literature and proposes a standardization of phases of learning curves for RYGB and LSG. METHODS A systematic literature search was performed using PubMed, Web of Science, and CENTRAL databases. All studies specifying a number or range of approaches to characterize the learning curve for RYGB and LSG were selected. RESULTS A total of 28 publications related to learning curves for 27,770 performed bariatric surgeries were included. Parameters used to determine the learning curve were operative time, complications, conversions, length of stay, and blood loss. Learning curve range was 30-500 (RYGB) and 30-200 operations (LSG) according to different definitions and respective phases of learning curves. Learning phases described the number of procedures necessary to achieve predefined skill levels, such as competency, proficiency, and mastery. CONCLUSIONS Definitions of learning curves for bariatric surgery are heterogeneous. Introduction of the three skill phases competency, proficiency, and mastery is proposed to provide a standardized definition using multiple outcome variables to enable better comparison in the future. These levels are reached after 30-70, 70-150, and up to 500 RYGB, and after 30-50, 60-100, and 100-200 LSG. Training curricula, previous laparoscopic experience, and high procedure volume are hallmarks for successful outcomes during the learning curve.

Abstract
Laparoscopic cholecystectomy (LC) is widely accepted as the standard treatment for benign gall bladder diseases in humans because it has proven to be less invasive and safer than are
traditional methods. However, the efficacy of LC in dogs remains unclear. The present study aimed to examine the short-term outcome of LC for benign gall bladder diseases in dogs. We
enrolled 76 consecutive dogs that underwent LC for benign gall bladder diseases at our hospital between April 2008 and October 2016. Dogs with jaundice, gall bladder ruptures, abdominal
effusion, or extrahepatic biliary obstruction were not excluded from the indication. Factors including age, body weight, sex, clinical sign, disease, operative time, conversion to open
surgery, perioperative complications, and postoperative hospital stay were investigated. The median age of the dogs was 11 years, and the median body weight was 5.4 kg. Fifty percent of the
dogs exhibited no symptoms at the initial visit. Preoperative elevation of total bilirubin levels was observed in 16 dogs (21%). LC was successfully completed in 71 dogs (93%); the median
operative time was 124 min. Although gall bladder ruptures were observed in 2 (2.6%) dogs, the operations were completed successfully. Three dogs (4.1%) had to be converted to open
cholecystectomy and 2 (2.6%) underwent reoperation. Two dogs (2.6%) died intraoperatively and 2 (2.6%) died postoperatively. LC was a feasible, safe, and appropriate procedure considering
the current operative indications for benign gall bladder diseases in dogs.

Abstract
BACKGROUND Laparoscopic gastric bypass (LGBP) is the most common bariatric procedure worldwide. The gastrojejunostomy can be stapled with a circular or linear stapler, each with their own specific advantages. We have evaluated differences in postoperative complications between the two techniques. METHODS We studied operative data and postoperative complications in 560 patients (79.8 % females, median age 42, BMI 42.5) operated with LGBP between 2008 and 2012 at our center. The gastrojejunostomy was initially performed using a circular stapler (CS) in 288 patients and later by linear stapler (LS) in 272. Complications, operative time, and length of stay were retrieved from our database. The risk of developing a port site infection was evaluated with multivariate logistic regression. RESULTS Port site infections were more common with CS than LS, 5.2 and 0.4 %, respectively (p < 0.01). Multivariate analysis demonstrated CS to be an independent risk factor for port site infections (OR 16.3 (2.09-126), p < 0.01), as well as for stomal ulcers (OR 10.1, 1.15-89, p = 0.04). Major postoperative complications remained unchanged (anastomotic leak 1.0 vs. 1.1 %, abscess 0.7 vs. 0.4 %), while operative time and length of stay were found to be shorter using the LS (122 vs. 83 min, p < 0.001 and 4 vs. 3 days, p < 0.001). CONCLUSIONS The linear stapled technique yielded lower incidence of port site infections, probably by avoiding the passage of a contaminated circular stapler through the abdominal wall. No difference in major complications was seen, but operative time was shorter using a linear stapler instead of a circular stapler.

Abstract
INTRODUCTION Controversy exists between laparoscopic Roux-en-Y gastric bypass and laparoscopic adjustable gastric banding in super-obese patients. METHODS This is a retrospective review of prospectively collected data. A total of 102 consecutive super-obese (body mass index >50) patients underwent laparoscopic Roux-en-Y gastric bypass (Group 1), and 79 consecutive ones underwent laparoscopic adjustable gastric banding (Group 2). Early complications and weight loss outcomes were evaluated. RESULTS No significant difference was found in operative mean (± standard deviation) time (93.5 ± 33 vs 87.7 ± 39 min, p = 0.29), hospital stay (2.68 ± 2.27 vs 2.75 ± 1.84 days, p = 0.80), or overall early postoperative morbidity (17.65% and 10.12%, p = 0.20). Intra-operative complications occurred in six patients (5.9%) in Group 1 and none in Group 2 (0.0%, p = 0.04). Mean excess weight loss percent at 6 and 12 months in Group 1 was 44.75% ± 11.84% and 54.71% ± 18.18% versus 26.20% ± 12.42% and 31.55% ± 19.79% in Group 2 (p < 0.001). CONCLUSION There seems to be no significant differences in early complications between laparoscopic Roux-en-Y gastric bypass and laparoscopic adjustable gastric banding operations in the short term. Weight loss and excess weight loss percent at 6 and 12 months are significantly better after laparoscopic Roux-en-Y gastric bypass.

Abstract
Bariatric surgery is gaining in popularity in the United States and around the world as a treatment for morbid obesity. Patients seek surgery in order to lose weight and limit the long-term effects of insulin-resistant diabetes, heart disease and lung disease, including risk of sudden death. While gastric bypass in patients with morbid obesity can reduce the risk of diabetes and myocardial infarction to population levels, the risk of death remains increased. These patients may die suddenly and unexpectedly as a direct result of surgery, as an indirect result of surgery, or of end-organ damage wrought by years of obesity, completely unrelated to the surgery. Proper forensic pathologic assessment of these patients requires an understanding of the anatomic changes caused by bariatric surgery, the complications and the metabolic consequences of the different procedures. In order to better understand this subgroup of patients, a search of the peer-reviewed medical literature at the National Library of Medicine was conducted for articles using the keywords bariatric, surgery, gastric bypass, autopsy, review, toxicology, alcohol, drug, ethanol, absorption, elimination, litigation, forensic, and death. This review outlines the most common laparoscopic and open surgical procedures; the common immediate post-surgical complications that lead to morbidity and mortality; forensic toxicological considerations in bariatric patients; and the long-term complications and other causes that could lead to unexpected death in these patients.
