Simpler Weight-Loss surgery put to the test against gold standard
NCT ID NCT06057597
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two types of gastric bypass surgery for people with severe obesity: the standard Roux-en-Y and a simpler omega (one-anastomosis) bypass with a shorter intestinal loop. Researchers want to see if the omega procedure is just as good at helping patients lose weight and has a similar rate of nutritional problems. About 368 adults will be followed for two years after surgery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Gastric bypass surgery (omega or Roux-en-Y)
What this could lead to
If successful, this could offer a simpler, equally effective surgical option for weight loss with fewer complications.
What could go wrong
This is a non-inferiority trial, so it may only show the omega bypass is not worse, not better. Results are at 2 years, and long-term effects are unknown.
