Objective: Endoscopic sleeve gastroplasty (ESG) has gained global adoption but our understanding of its mechanism(s) of action and durability of efficacy is limited. We sought to determine changes in gastric emptying (GE), gastric motility (GM), hormones and eating behaviours after ESG. Design: A priori-designed single-centre substudy of a large...

Introduction Endoscopic sleeve gastroplasty (ESG) is a novel endoscopic bariatric therapy that complements current medical and surgical therapeutic offerings for weight management and fills an unmet need. Few meta-analyses compared ESG to laparoscopic sleeve gastrectomy (LSG). However, these studies relied on indirect evidence derived from non-comp...

Background: Endoscopic bariatric therapies can help address widening management gaps in obesity. Their ability to facilitate weight loss is largely tied to influences on appetite through perturbations of gastric emptying and accommodation. As these tools gain traction in obesity therapy, their physiologic underpinnings require exploration, which m...

Background: Given the low survival rate in pancreatic cancer, new therapeutic techniques have been explored, especially for unresectable or borderline resectable disease. Endoscopic ultrasound (EUS) provides real-time imaging and minimally invasive access for local and targeted injection of anti-tumor agents directly into the pancreatic tumor. Lim...

Background and study aims Management of malignant gastrointestinal obstruction (MGIO) is more challenging in the presence of peritoneal carcinomatosis (PC). Outcomes data to guide the management of MGIO with PC are lacking. We aimed to compare the clinical outcomes and adverse events between endoscopic and surgical palliation and identify predictor...

The prevalence of obesity has been increasing on a global scale. However, less than 1% of patients eligible for bariatric surgery actually undergo weight loss surgery. Endobariatric therapies (EBTs) have emerged to bridge the obesity treatment gap, as they are less invasive, highly effective, and more broadly applicable to patients with mild to mod...

Background Intragastric balloons have been used to bridge the obesity treatment gap with the benefits of being minimally invasive but still required endoscopy. The Elipse intragastric balloon (EIGB) is a swallowable balloon that is spontaneously excreted through a natural orifice at approximately 16 weeks. Several concerns exist, including the trea...

Background The intragastric balloon (IGB) is commonly used for weight loss. Identifying patients who are most likely to tolerate and benefit from IGB therapy will optimize outcomes. Our aims were to prospectively utilize a gastric emptying study to predict intolerance and treatment response with a single fluid-filled IGB and to develop a physiologi...
