Banded Gastric Bypass

General patient information

Banded Roux-en-Y Gastric Bypass (BRYGB) is a surgical procedure that can be performed by minimally invasive (keyhole) surgery. The procedure reduces food intake and reduces the absorption of nutrients from the food. Absorption of nutrients is limited because part of the intestines is bypassed and not used.

The volume of the stomach pouch by BRYGB is between 15 and 25 ml. The junction between the stomach pouch and small bowel is controlled by a silastic ring (Minimizer Ring). The alimentary limb (AL, green in the image) in BRYGB is 120 – 150cm long and the biliopancreatic limb (BPL, pink in the image) consists of 50 cm of small intestine.

Banded Gastric Bypass

In the “banded” bypass, a large portion of the stomach is surgically reduced by cutting and stapling (see pink shading). This results in a new stomach pouch which is roughly the size of a walnut.

With the “banded” gastric bypass, a silastic ring (Minimizer) is implanted approximately 2cm above the stomach to small intestine connection (anastomosis). This is indicated by the pink ring on the green shading. The Minimizer Ring will protect the anastomosis and also help reduce the incidence of future pouch dilatation.

Banded Roux-en-Y Gastric Bypass has been performed for many years and has been proven to increase the excess weight loss in the long term.
