Can a second bypass surgery rescue failed weight loss?

NCT ID NCT04165694

First seen Aug 06, 2026 · Last updated Aug 07, 2026 · Updated 1 time

Summary

This study looks at whether a follow-up surgery called Single Anastomosis Duodenal Ileal Bypass (SADI) can help people who had a sleeve gastrectomy but didn't lose enough weight. Participants are adults with severe obesity who lost less than 10% of their body weight after the first surgery. The goal is to see if this second procedure leads to more weight loss and improves obesity-related health problems.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Single Anastomosis Duodenal Ileal Bypass (SADI), a surgical procedure that reroutes the intestine to reduce calorie absorption
What this could lead to
If successful, this could offer a reliable second-step surgery for people with severe obesity who didn't lose enough weight after a sleeve gastrectomy, potentially improving weight loss and related health conditions.
What could go wrong
This is a relatively small study, and the procedure carries surgical risks like any major operation. Results may not apply to all patients, and long-term benefits are still uncertain.
