This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial compares two different ways surgeons can revise a gastric bypass surgery if it did not work as expected. About 150 people who had a gastric bypass but did not lose enough weight — or gained weight back — will be randomly assigned to receive one of two revision surgeries. The study will measure which approach helps people lose more weight and causes fewer nutritional problems.
Up to one in three people who have gastric bypass surgery either do not lose enough weight or regain significant weight after their surgery. Right now, doctors do not agree on the best way to fix a failed gastric bypass, so this trial aims to find out which revision surgery technique works best.

If you qualify, you will be randomly assigned to one of two revision surgery groups. Both surgeries are performed using minimally invasive (laparoscopic) techniques and involve rearranging parts of your intestines to increase weight loss. After your surgery, you will attend follow-up visits to measure your weight loss, check your nutrition levels, and report on your health and quality of life over the first year and beyond.
