Mini Gastric Bypass Surgery also known as single anastomosis gastric bypass, in which a long gastric pouch is created and is directly attached to the small intestine. It is a simple, safe, rapid and powerful bariatric operation. It leads to an excess weight loss of 70 to 80% at the end of 2 years. Patients need to be on nutritional supplements like iron, calcium, proteins and multivitamins for life.
Mini Gastric Bypass (MGB) is a modification of Roux en y gastric bypass. In this procedure, a long gastric sleeve is created along the lesser curvature starting 3cm before the pylorus and is directly connected to small intestine with a bigger (4cm) anastomosis, bypassing the duodenum and proximal jejunum. Because of this bigger anastomosis, patient can eat much more than a Roux en y gastric bypass patient. Unlike gastric bypass surgery, digestive enzymes and bile are not diverted away from the stomach after mini gastric bypass. It is mainly a mal-absorptive procedure.
