Laparoscopic gastric bypass vs banding for weight loss
Part of Hormones & metabolism clinical trials.
This trial compares two types of minimally invasive weight-loss surgery: gastric bypass versus a gastric band. It looks at which approach works better and is safer for people who qualify for bariatric surgery and have not succeeded with supervised weight-loss programs.
Summary written for real people, not researchers, by Clin2.

This trial compares a “mini” gastric bypass procedure to help with weight loss in adults who qualify for bariatric (weight-loss) surgery. It’s testing whether the approach works well and is safe for people who meet the study requirements.
This study compares two types of minimally invasive surgery for weight loss: one done with a robot and one done with a laparoscope. If you are planning a Roux-en-Y gastric bypass, doctors want to see which method works better and is more cost-effective.
This trial compares changes in stool after two common weight-loss surgeries: sleeve gastrectomy and gastric bypass. It aims to understand how these surgeries affect digestion and gut health.
This trial compares a new version of gastric bypass (with a longer 150cm bypassed segment) to the standard Roux-en-Y gastric bypass to see which leads to better weight loss and health improvements. It is for people with severe obesity who are already scheduled for surgery and want to help find the best procedure.
This study compares two types of weight-loss surgery to see which is better for helping people with severe obesity. If you have a high BMI and are willing to follow up after surgery, this trial might help you decide which procedure is right for you.
This study compares two surgical methods used for weight loss: OAGB and a longer-limb Roux gastric bypass. It may help find which option works best for people with severe obesity and obesity-related health problems.
