Summary

This study follows 234 people who regained weight after a sleeve gastrectomy and are now getting a revision surgery. The goal is to compare three procedures—SADI-S, RYGB, and OAGB—to see which leads to the most weight loss, fewest complications, and best nutritional outcomes. Participants must have a BMI around 45 and have regained weight after their first surgery.

What this could lead to

What could go wrong
