Summary

This trial tests whether converting a prior sleeve gastrectomy to a procedure called intestinal transit bipartition can improve stomach emptying, reduce acid reflux, and help with weight control. Forty adults who had sleeve gastrectomy and now have weight regain or reflux will undergo the revisional surgery and be followed for six months. Researchers will measure changes in gastric emptying, reflux symptoms, hormone levels, and gut health.

What this could mean

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

Active substance
a revisional surgical procedure called intestinal transit bipartition
What this could lead to
If successful, this approach could offer a surgical option for people who regain weight or suffer from reflux after sleeve gastrectomy.
What could go wrong
This is a small, early-stage study with only 40 participants, and revisional surgery carries risks such as complications from anesthesia, infection, or bowel issues.
