Mini Gastric Bypass

In this technique, the stomach is shaped like a tube in about 2 cm thickness and 50-60 cc volume (volume of 4 spoons of water) as in sleeve gastrectomy and separated from the residue stomach. The new small and narrow gastric tube is sutured with a part at the middle of small intestines without making an incision (200th cm since from Treitz). The biggest difference of this technique from RYGB is that intestinal integrity is not disrupted, and the procedure is done at a single place.

Mini gastric bypass is an effective surgery combining some features of standard gastric bypass and sleeve gastrectomy operation. The upper part of the stomach is shaped like a tube and connected to small intestines.

Mini gastric bypass is not a weight loss procedure on its own. It can also be applied to patients who have previously had a gastric band or sleeve gastrectomy operation but could not lose weight and for those who had complications because of the gastric band and decided to undergo revision operation.

In this operation, the upper part of the stomach is separated in the form of a thin tube from the rest of the stomach. It is shaped like a new and smaller stomach. This new stomach is then connected to the place right after the 150-200 cm first part of small intestines. The rest of the stomach and small intestines continues to stay in the body but does not function in digestion.

How Does Mini Bypass Operation Help Losing Weight?

1. Since the signals between stomach and brain changes, feeling of hunger decreases.
2. You can get fuller with less food.
3. Since a part of small intestines does not play role in digestion, less amount of consumed calories are absorbed.

Long Term Effects of Mini Gastric Bypass

About 70-85% of excess weight is lost until 2 years after the operation.
A lot of diseases related to being overweight such as sleep apnea, type 2 diabetes, joint diseases, hypertension and polycystic ovarian syndrome improve more with the operation or completely disappear.
