Roux-en-Y Gastric Bypass

gastric_fullThe Roux-en-Y Gastric Bypass is considered both a restrictive and malabsorptive procedure. In this procedure a small upper stomach pouch is created by stapling and dividing the stomach into 2 portions. The lower portion of the stomach will no longer serve as a reservoir for food. An opening is created in the upper pouch and a Y shaped section of small intestine is connected to the stomach pouch, bypassing the first part of the small intestine. Patients lose weight because the small pouch restricts the amount of food which can be ingested and the bypassing of the first part of the small intestine decreases the absorption of some calories and nutrients. This procedure is also performed laparoscopically.
