Surgical Procedures & Innovations  Banded Gastric Bypass


This procedure is a combination of the Roux-en-Y gastric bypass and the once common Vertical Banded Gastroplasty. In this operation, the implantation of a plastic band around the stomach pouch (resulting in significant restriction of food intake) in addition to the changes of absorption seen from the gastric bypass, may have been associated with 20% more excess weight loss than one would expect from gastric bypass alone. Therefore, expected weight loss is 60-90% of a patient's excess weight.
