Gastric Bypass (RNY)

The Laparoscopic Roux-n-Y Gastric By-Pass is the most common of malabsorptive and restrictive surgical procedures. In the Roux-n-Y a small stomach pouch is created to restrict food intake. During the surgery we create a pouch along the lesser curve of the stomach which helps to reduce stretching. Next the intestine is severed, the lower section of the small intestine is attached to the pouch to allow food to bypass the remaining stomach, duodenum (the first segment of the small intestine) and the first portion of the jejunum (the second segment of the small intestine) The jejunum portion of the intestine is then attached back to the lower intestine forming a Y pattern to the intestine. This bypass reduces the amount of calories and nutrients the body absorbs.

The RYGBP has been proven in numerous studies to result in durable weight loss and an improvement in weight-related medical illnesses. Half of the weight loss often occurs during the first six months after surgery; weight loss usually peaks at 18-24 months. . The laparoscopic approach to RYGBP was initiated in an effort to improve the early outcomes including a reduction in postoperative complications arising from a large incision in a severely obese patient.
