What is the Mini Gastric Bypass?
The mini gastric bypass (MGB) is considered a new and promising option for patients to lose weight. It effectively combines the gastric sleeve and the gastric bypass surgery principles with less cutting and less risk.
This means that it is quicker and safer without being less effective.
The stomach is divided using a staple device, so you end up with a bigger stomach (below the staple line) and a small stomach pouch shaped like a tube, with a capacity of 50 ml.
Then, the smaller stomach is sutured to a loop of the intestine. This is called an anastomosis or joint between a part of the stomach and the small bowel, bypassing approx. 200 cm of intestine.
On the other hand, the bigger stomach, which no longer is available to receive food, still produces gastric juices and enzymes that travel through the small bowel.
