Evolution of Bariatric Surgery

Bariatric surgery is the result of approximately 50 years of improvement in
surgical practice. The first bariatric operation was a jejunoileal bypass performed in 1956, but due to severe comorbidities such as dehydration and malabsorption, this practice was abandoned for the gastric bypass (gastroplasty w/ loop gastrojejunostomy) procedure in 1960’s by Edward Mason. The exact mechanism of bypassing the stomach was changed multiple times over the course of the late 20th century, but the concept of bypassing the stomach has held true and is one of the accepted standards today for bypass surgery. Most surgeons today perform a variation
of a Roux-En-Y bypass which consist of a gastoplasty (reduction of stomach size) and a gastrojejunostomy (connection of the newer smaller stomach to small intestine further down the digestive tract). Other procedures commonly performed include gastric sleeve, gastric band (both reduce the overall active stomach size), and gastric stimulators.
