The Mini Gastric Bypass is a modernized version of the traditional Gastric Bypass (Roux-en-Y) procedure. It is a simpler, faster procedure that requires only one anastomosis (surgically joining parts of the body) compared to a traditional Gastric Bypass which requires two. It is performed laparoscopically.
Although it is called a Mini Gastric Bypass to differentiate it from the traditional Gastric Bypass, weight loss results are similar.
The stomach is divided into a smaller portion, or pouch that is approximately 1/4 of the existing stomach. The gastric pouch is then joined to the small intestine.
This results in the majority of the stomach and approximately 1/3 of the small intestine being ‘bypassed’ when you eat food. This means it is not involved in the digestion or absorption of the food you eat.
