Roux en Y Gastric Bypass

The procedure involves creating a small gastric pouch (with a volume of 30 - 50 ml), completely separated from the rest of the stomach, into which an "intestinal loop" is anastomosed.

This results in a gastric pouch roughly the size of a small coffee cup, limiting the amount of food it can hold. The food then follows a new route, bypassing (diverting) the stomach, duodenum, and the first portion of the small intestine.

In a gastric bypass, no part of the stomach or intestine is removed, making the procedure virtually reversible.

It is the oldest bariatric procedure, offering superior benefits for reflux management. Over the past 10 years, the risk of complications has significantly decreased, now matching that of the sleeve gastrectomy with a similar hospital stay.
