NCT02545647

Brief Summary

A Roux-en-Y Gastric Bypass (RYGB) is on the long term not always successful in every patient because weight regain can occur. An intervention to prevent weight regain in the future is to place a silicone band (non-adjustable) around the pouch of the RYGB (Banded-RYGB: BRYGB) which increases weight loss and decreases weight regain on the longer term. The question is whether primary application of a banded bypass gives a greater weight loss and / or prevent weight regain in the future versus a standard RYGB.
