BACKGROUND: Obesity is steadily growing to be the largest threat to human health in this century, not only increasing prevalence of obesity-related co-morbidity but also impairing health-related quality of life (QoL). Bariatric surgery has shown to improve co-morbidity as well as QoL. OBJECTIVES: To assess the differences in improvement in QoL for the 2 most performed procedures: laparoscopic sleeve gastrectomy (SG) and laparoscopic Roux-en-Y gastric bypass (RYGB)...

BACKGROUND: Bariatric surgery has proved to be an effective strategy in treating obesity. However, randomized controlled trials (RCTs) of 3 most common bariatric surgery procedures, Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and laparoscopic adjustable gastric band (LAGB), reported inconsistent results. We performed a systematic review and network meta-analysis to synthesize evidence of effectiveness of the 3 common bariatric procedures from relevant RCTs. METHODS: The present study was a systematic review and network meta-analysis of RCTs...

BACKGROUND: Laparoscopic sleeve gastrectomy is a common surgical management of morbid obesity. Major complication rate is 3-8%. Staple line leak is one of the most serious complications. In a small group of patients, a gastro-pulmonary fistula is formed. Endoscopic and minimally invasive measures are the first line of treatment with considerable success rate. There are very poor data in the literature what should be done in cases of failure. In this paper, we report our positive experience with definitive surgical repair...

PURPOSE: Despite evidence of oncologic benefits from extended (D2) lymphadenectomy in gastric cancer from many East Asian studies, there is persistent debate over its use in the West, mainly due to perceived high rates of morbidity and mortality. This study evaluates the safety and efficacy of D2 dissection in a high-volume North American center. METHODS: A prospectively entered database of all patients undergoing gastrectomy for cancer at a North American referral center from 2005 to 2016 was reviewed...

BACKGROUND: Postoperative nausea and vomiting (PONV) is problematic in bariatric surgery patients and has negative impacts on perioperative outcome. Antiemetic prophylaxis may reduce PONV. Perioperative antiemetic prophylaxis or therapy is crucial and may enhance fast-track bariatric surgery. This study examined the impact of intraoperative multimodal antiemetic prophylaxis on fast-track bariatric surgery. METHODS: This prospective observational clinical study explored the perioperative data of 400 consecutive laparoscopic bariatric surgery patients, over a 6-year period...

Objective: Morbidly obese patients are traditionally hospitalised following bariatric surgery. However, laparoscopic-adjustable gastric banding (LAGB) is amenable for ambulatory care. We hypothesised that the majority of patients can receive an ambulatory LAGB and that both surgical and anaesthetic perioperative factors will significantly affect non-ambulatory LAGB outcomes. Methods: Medical records of 201 consecutive LAGB patients performed at the University of Kansas Medical Centre during a 3-y period were reviewed...

BACKGROUND: Bariatric surgery is associated with increased thromboembolic risk, which may extend well beyond hospital stay. The hemostatic mechanisms implicated in this risk are not well established. OBJECTIVES: We aimed to determine the dynamics of hemostatic changes and procoagulant potential among patients undergoing laparoscopic sleeve gastrectomy, during both the early and late postoperative periods. SETTING: A university hospital. METHODS: Patients who underwent laparoscopic sleeve gastrectomy were recruited consecutively to this study...

BACKGROUND: Ten to 50% of patients who received restrictive bariatric operations may require reoperation for unsatisfactory weight loss or weight regain. Failed restrictive procedures are usually managed with conversion to another bariatric procedure with a favor of conversion to laparoscopic gastric bypass. Our aim is to evaluate two different bypass techniques, laparoscopic RY gastric bypass (RYGB) versus single-anastomosis (mini-) gastric bypass (SAGB) as a revision option (R-RYGB and R-SAGB) for failed restrictive bariatric operations...

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) affects 75 to 100% of the patients undergoing bariatric surgery (BSx), with non-alcoholic steatohepatitis (NASH) being present in 24 to 98% of the patients. We do not know whether these rates were before or after a very low calorie diet (VLCD) often prescribed before laparoscopic BSx and what is the prevalence of NAFLD post-VLCD. PURPOSE: The purpose of this study is to determine the prevalence of simple steatosis (SS) and NASH in obese individuals undergoing BSx post-VLCD and assess biochemical markers pre- and post-VLCD in a subgroup of patients...

Bariatric surgery is currently the most effective therapy for type 2 diabetes. However, the mechanisms underlying its beneficial effects remain elusive. Here, we studied the effects of bariatric surgery on circulating meteorin-like (Metrnl) and oncostatin m (OSM) levels, two hormones intimately linked to energy homeostasis. Metrnl and OSM levels were assessed at baseline, 6, and 12 months after laparoscopic sleeve gastrectomy (LSG) in 25 patients with obesity, as well as in 33 normal-weight controls. At baseline, patients with obesity showed lower Metrnl and higher OSM levels compared to controls...

BACKGROUND: The laparoscopic Roux-en-Y gastric bypass (LRYGB) has been the gold standard for bariatric surgery, but recently, the laparoscopic sleeve gastrectomy (LSG) has gained popularity. At present, limited data is available on the long-term complications of these two types of surgery. The aim of this retrospective study was to compare the 2-year data about late (more than 30 days after surgery) complications that were treated surgically or endoscopically after LRYGB and LSG operations in a large hospital area with a single patient database...

INTRODUCTION: Leak following bariatric surgery continues to be associated with morbidity and rarely mortality. With improvement in surgical techniques and stapler design, leak rates have reduced drastically. Intra-operative high pressure Methylene blue leak test (HPMB) is one of the techniques employed to confirm integrity of anastomoses and staple lines. Despite this, evidence for its use remains limited. We evaluated the role of HPMB in detecting and preventing leaks. METHODS: A retrospective cohort of consecutive patients who underwent primary or revisional Laparoscopic Sleeve Gastrectomy (SG) or Laparoscopic Roux-en-Y Gastric bypass (RYGB) under the care of five surgeons in three centres across Birmingham, UK, between 2012 and 2016 were assessed...

BACKGROUND: Obesity is a global pandemic leading to increased mortality and increased risk of cardiovascular disease. Bariatric surgery is an established treatment of obesity leading to weight loss and reduction of mortality. To further elucidate how bariatric surgery improves metabolic control, we explored the fatty acid (FA) profiles in morbidly obese subjects treated with lifestyle intervention and subsequent bariatric surgery. METHODS: The intervention group consisted of 34 morbidly obese patients scheduled for bariatric surgery and the control group of 17 non-obese patients scheduled for elective laparoscopic procedures...
