Bariatric Surgery
Gastric Bypass
Gastric bypass, or gastric short-circuiting, is a bariatric surgery procedure combining restriction and malabsorption. It involves creating a small gastric pouch connected directly to the small intestine, thus bypassing most of the stomach and the beginning of the small intestine. It is the standard procedure for severe obesity with comorbidities.

How the Procedure Is Performed
Laparoscopy
The procedure is performed laparoscopically.
Creation of the gastric pouch
The surgeon creates a small gastric pouch (30-50 ml) from the upper part of the stomach, separating it from the rest of the stomach.
Division of the small bowel and alimentary limb
The small intestine is then cut, and the distal portion is connected to this pouch (alimentary loop).
Reconnection of the digestive secretions
The proximal portion is reconnected further down to allow digestive secretions to reach the food.
Roux-en-Y configuration
This Y-shaped anastomosis creates a bypass that limits absorption.
