Gastric Bypass
Abstract
Gastric bypass is a malabsorptive and restrictive bariatric procedure first described by Mason and Ito in 1967. Their original gastric bypass consisted of a 100–150 ml horizontal pouch anastomosed to a loop of proximal jejunum. In 1977 Griffen introduced the Roux-en-Y gastrojejunostomy in place of the loop gastrojejunostomy, and in 1983 Torres stapled the stomach vertically rather than horizontally, a modification that has become the standard method for constructing the gastric pouch. The laparoscopic approach to gastric bypass has been described by Wittgrove, Clark and Tremblay in 1994. To date, gastric bypass is one of the most applied bariatric procedures. According to a 2008 survey on bariatric surgery, it accounts for 51 % of bariatric procedures in the USA and 49.3 % worldwide.
