OBJECTIVE: This study aimed to compare midterm and long-term weight loss and resolution of co-morbidity with laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG). SUMMARY: LRYGB and LSG are the most common procedures performed in bariatric surgery. However, their weight loss efficacy in the midterm and long-term has not been well compared. METHODS: A meta-analysis was performed by systematically identifying comparative studies conducted until the end of June 2016 that investigated weight loss outcome and resolution of co-morbidities (type 2 diabetes mellitus, hypertension, hyperlipidemia, hypertriglyceridemia, and obstructive sleep apnea) with LRYGB and LSG in the midterm (3-5 years) and long term (≥5 years)...

BACKGROUND: Recent data show that some patients will have insufficient weight loss or experience weight regain after sleeve gastrectomy. Dilation of the sleeve over time or use of an inadequate technique may contribute to relapse of morbid obesity. Repeat sleeve gastrectomy is the most obvious option but requires stapling of scarred tissue, has a higher risk of leakage, and is prone to re-enlargement with time. We herein describe a simple and innovative technique with which to revise vertical sleeve gastrectomy (VSG) into functional single-anastomosis gastric bypass (f-SAGB)...

Background: Roux-en-Y gastric bypass (RYGB) is a standard therapy in bariatric surgery. Sleeve gastrectomy and gastric banding, although with good results in the literature, are showing higher rates of treatment failure to reduce obesity-associated morbidity and body weight. Other problems after bariatric may occur, as band erosion, gastroesophageal reflux disease and might be refractory to medication. Therefore, a laparoscopic conversion to a RYGB can be an effective alternative, as long as specific indications for revision are fulfilled...

Background: Bariatric surgery is performed all over the world with close to 500.000 procedures per year. The most performed techniques are Roux-en-Y gastric bypass and sleeve gastrectomy. Despite this data, the most effective procedure, biliopancreatic diversion with or without duodenal switch, represents only no more than 1.5% of the procedures. Technical complexity, morbidity, mortality, and severe nutritional adverse effects related to the procedure are the main fears that prevent most universal acceptance...
