Summary: The goal of this clinical trial is to investigate protein digestibility after bariatric surgery. Does protein digestibility decrease after Roux-en-Y-Gastric Bypass? Does protein digestibility decrease after Sleeve Gastrectomy surgery? Does protein digestibility effect the ability to meet protein requirements?

Summary: This study aims to determine whether Ropivacaine-Poloxamer 407 hydrogel provides non-inferior pain control compared to TAP block for patients undergoing minimally invasive gastrectomy. The results will guide postoperative pain management practices and enhance recovery protocols for gastric cancer surgery.

Summary: Obesity is a complex chronic disease that has become a major public health concern worldwide, with the prevalence of obesity increasing dramatically over the past few decades. Patients with morbid obesity pose a challenge for perioperative pain management. High ceiling analgesics-opioids have limited role due to safety concerns for patients with or without obstructive sleep apnea . Insufficient po...

Summary: With this trial, the aim is to assess the benefits and harms of a non-surgical intensive weight loss intervention that includes total dietary replacements, behavioural support and weight-loss medication compared with bariatric surgery for people with severe and complex obesity. The interpretation of the results will help inform future care pathways for people with obesity in whom bariatric surgery...

Summary: This pilot study aims to provide valuable insights into the optimal surgical approach for robotic distal gastrectomy. By comparing full robotic procedures with assistant-controlled techniques, the results may guide future practice, enhancing surgical efficiency, reducing costs, and improving patient outcomes.

Summary: Achalasia is a neuro-degenerative disorder marked by changes in the peristalsis of the esophagus and the lack of relaxation in the lower esophageal sphincter (LES), thought to be due to damage to the myenteric plexus with an unknown cause.1 Per-oral endoscopic myotomy (POEM) is an established endoscopic treatment modality for achalasia. Leading gastrointestinal (GI) societies endorse POEM as one o...

Summary: Researchers are trying to identify predictors for gastroesophageal reflux disease after sleeve gastrectomy.

Summary: This prospective randomized non-inferiority study will be conducted to compare the analgesic anti-emetic effects of intravenous ondansetron versus perineural ondansetron in patients undergoing laparoscopic sleeve gastrectomy.

Summary: This is a prospective sham study to investigate the role of transpyloric stenting with lumen apposing metal stent (LAMS) as a predictor for clinical response to gastric per-oral endoscopic pyloromyotomy (GPOEM) for refractory gastroparesis. The study hypothesizes that clinical improvement with transpyloric stenting in patients with refractory gastroparesis is a predictor of subsequent clinical suc...

Summary: The study evaluates the efficacy of Ropivacaine-Poloxamer 407 hydrogel in reducing postoperative pain following open gastrectomy.

Summary: The aim of this study is to determine the feasibility and effectiveness of endoscopic anastomosis of sleeve gastrectomy to ileum with a lumen apposing metal stent (LAMS) after a failed sleeve gastrectomy.

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.
