Mini Gastric Bypass
The stomach is stapled into a small upper pouch and a large lower pouch. The jejunal small intestine is connected to the upper part of the stomach, bypassing the duodenum and major part of the stomach.
While traditional gastric bypass surgery results in excellent weight loss, the procedure is technically challenging and carries a 7% complication risk. The risk of mortality (death) is very low, about 0.5% according to most studies.
The mini-gastric bypass procedure has gained popularity in recent years. The mini-gastric bypass was originally developed by Dr. Robert Rutledge in 1997. The mini-gastric bypass is quicker, technically easier and carries a lower complication rate compared to traditional gastric bypass surgery, 2.9% (2012 MGB study).
