NCP Obesity : Surgical Interventions (Gastric Partitioning / Gastroplasty, Gastric Bypass)

Weight reduction surgery has been reported to improve several comorbid conditions such as sleep apnea, glucose intolerance and frank diabetes, hypertension, and hyperlipidemia. A number of surgical treatments for morbid obesity have been tried and discarded because of ineffectiveness or complications. The procedure of choice is vertical-banded gastroplasty, although the Roux-en-Y gastric bypass is also performed. Procedure may be performed via open abdominal incision or laparoscopy.

Gastroplasty (gastric stapling/banding): A small pouch with a restricted outlet is created across the stomach just distal to the gastroesophageal junction. A small opening remains, through which food passes into stomach. Vertical banded gastroplasty (VBG) is accomplished by placing rows of staples vertically in the strongest sidewall of the stomach and insertion of polypropyline band around the outlet of the resulting pouch.

Gastric bypass (Roux-en-Y): Anastomosis of a segment of the small intestine to upper portion of stomach that has been partitioned by a horizontal staple line or banding.
