Summary: This study is being done to better understand the relationship between inflammation in adipose tissue (AT), abnormal deposition of fat around the liver and how this affects its appearance and function and ultimately insulin resistance.

Summary: AVX-001 (LUCIDITY) is a Phase 3 study to evaluate avexitide compared to placebo in participants with post bariatric hypoglycemia (PBH) related to Roux-en-Y gastric bypass (RYGB). The study will assess avexitide compared to placebo for safety and efficacy, measured by reduction of hypoglycemic events. The study includes a Screening period with a Run-in period (of up to 6- and 3-weeks, respectively)...

Summary: The primary objective of this open-label pilot study is to investigate whether an endoscopically placed lumen apposing metal stent is an effective alternative to surgery in patients that have a clear indication for reversal of their gastric bypass.

Summary: Given the limited long-term effectiveness of traditional weight loss methods, bariatric surgery is increasingly becoming the preferred option for sustained weight loss. With the ascendancy of the laparoscopic approach, the two most common procedures are the Roux-en-Y gastric bypass (RYGB) and the vertical sleeve gastrectomy (VSG). Because bariatric surgery decreases nutrient intake through restric...

Methods: Adult participants (n=200) are randomly allocated to one of two groups: Experimental surgical bariatric group - the first (A) group: patients (n=100) (Same-Day\_FundoRingOAGB group); Active comparator surgical bariatric group - the second (B) group: patients (n=100) (Standard\_FundoRingOAGB group). Primary Outcome Measure: 1. The Extra Length of Stay in Same-Day and One-Day 2. Safety (Cases of Com...

Summary: Obesity has escalated to pandemic levels, impacting over 650 million adults globally and significantly contributing to the burden of non-communicable diseases such as type 2 diabetes, cardiovascular disease, obstructive sleep apnea, non-alcoholic fatty liver disease, and infertility. The chronic, multifactorial nature of obesity presents substantial challenges for long-term management, as lifestyl...

Summary: The overall goal of this project is to understand the mechanisms by which gastric bypass surgery improves glucose metabolism. The central hypothesis guiding this project is that the reconfiguration of intestinal transit with the Roux-en-Y will increase the release of insulinotropic GI hormones, termed incretins that improve insulin secretion and glucose metabolism. The study is divided into three ...

Summary: The purpose of this study is learn the effect of gastric bypass surgery and sleeve gastrectomy on glucose metabolism mediated by neural and hormonal factors initiated after eating.

Summary: RYGB (roux-en-y gastric bypass) has been reported to reverse type 2 diabetes (T2DM) immediately after surgery before any significant weight loss. In addition, a growing number of patients have been recognized with life-threatening hyperinsulinemic hypoglycemia several years following their surgery. While the mechanisms by which RYGB improves glucose metabolism or alters islet cell function in pati...

Summary: This randomized clinical trial aims to compare two surgical techniques for the treatment of obesity in patients who also have symptoms of gastroesophageal reflux disease (GERD). The study will compare Nissen-Sleeve Gastrectomy (N-SG)-a sleeve gastrectomy combined with a reflux-preventing procedure-to the Roux-en-Y Gastric Bypass (RYGB), which is the current standard surgical option for obese patie...

Summary: This study investigates the safety and efficacy of injecting N-butyl-2-cyanoacrylate (Histoacryl®) into the pancreatic parenchyma during pancreaticoduodenectomy (PD) to enhance the security of the pancreaticojejunostomy (PJ) anastomosis and reduce postoperative pancreatic fistula (POPF) rates.

Summary: To prevent refulx symptoms in a type of bariatric surgery, a suture is taken.there is no enough evidence in support of or against the suture. our study aims to compare the symptoms of patients in whom the suture is taken and in those in whom it is not.
