AbstractReviewed here are multiple mouse models of vertical sleeve gastrectomy (VSG) and Roux-en Y gastric bypass (RYGB) that have emerged over the past decade. These models use diverse approaches to both operative and perioperative procedures. Scrutinizing the benefits and pitfalls of each surgical model and what to expect in terms of post-operative outcomes will enhance our assessment of studies using mouse models, as well as advance our understanding of their translational potential. Two mouse models of bariatric surgery, VSG-lembert and RYGB-small pouch, demonstrate low mortality and most closely recapitulate the human...

AbstractThe purpose of this study was to investigate the relationship between bariatric surgery (laparoscopic sleeve gastrectomy [LSG] and laparoscopic Roux-en-Y gastric bypass [LRYGB]) and gastroesophageal reflux disease (GERD). The number of obese patients with newly onset, worsened, or improved GERD after bariatric surgery in each article were extracted. In the pooled analysis, LSG was associated with a higher risk of GERD than LRYGB (odds ratio [OR] = 5.10, 95% confidence interval [CI] 3.60 –7.23,p

The sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and single anastomosis duodenal-ileal bypass with SG (SADI-S) are recognized bariatric procedures. A comparison has never been made between these three procedures and especially in different body mass index (BMI) categories.

AbstractIntroductionBariatric surgery is increasingly performed. Since there are numerous surgical techniques, the effects of these on the esophageal function are still poorly understood. We aimed at assessing the effect of different techniques on esophagogastric junction (EGJ), esophageal peristalsis and reflux exposure using high-resolution manometry (HRM), and impedance-pH monitoring (MII-pH).MethodsAll obese patients underwent symptomatic questionnaires, endoscopy, HRM, and MII-pH before and 1  year after surgery. Esophageal function and EGJ were classified according to Chicago Classification V. 3.0. Intragastric ...

Study Objectives:Our objectives were to determine in an obese population (body mass index> 35 kg/m2) the number of patients, after gastric bypass (GBP), who no longer met French Ministry of Health criteria for utilizing positive airway pressure (PAP), and the predictive factors of obstructive sleep apnea (OSA) improvement.Methods:Between June 2012 and August 2014 we diagnosed OSA in 129 incident patients requiring PAP therapy before GBP. A postoperative sleep recording was undertaken for 44 of these patients after a weight loss of at least 10%.Results:Most of the patients showed severe OSA with a mean [standard deviatio...

ConclusionsPost bariatric surgery patients maintain a larger mass of high –metabolic rate trunk organs than non-operated controls of similar anthropometrics. Interpreting REE changes after weight loss requires an accurate understanding of fat-free mass composition at both the organ and tissue levels.Clinical Trial RegistrationLong-term Effects of Bariatric Surgery (LABS-2) NCT00465829

Obesity is a public health pandemic and leading contributor to morbidity and mortality. Endoscopic bariatric therapies have emerged as a viable minimally invasive treatment option to fill the therapeutic gap between conservative and surgical approaches. The ability to reliably place full-thickness sutures throughout the gastrointestinal tract has opened the door to novel endoscopic gastric restrictive procedures. A growing body of literature supports endoscopic sleeve gastroplasty as a safe, effective, and reproducible endoscopic treatment of obesity and metabolic syndrome. In addition, endoscopic sutured revision procedur...

ConclusionThe LSG and RYGB both impart dramatic meaningful loss in excess body weight. In addition, both the LSG and RYGB impart dramatic reductions in fat mass. However, both procedures induce loss of lean mass and there appears to be no difference between the two procedures in this regard despite their anatomic and physiologic differences.

SUMMARY OBJECTIVE To investigate the use of Bilevel Positive Airway Pressure (BiPAP) in morbidly obese individuals in two moments following bariatric surgery (Roux-en-Y gastric bypass): post-anesthetic recovery (PAR) and first postoperative day (1PO). DESIGN Randomized and blinded clinical trial. METHODS We studied 40 morbidly obese individuals aged between 25 and 55 years who underwent pulmonary function test and chest X-ray preoperatively, and on the day of discharge (2nd day after surgery). They were randomly allocated into two groups: PAR-G (BiPAP in PAR for one hour), and 1PO-G (BIPAP for one hour on the 1PO). RESULTS...
