Metabolic and Bariatric Surgery
Introduction
Metabolic and bariatric surgery is the surgical alteration of the stomach, intestine, or both to cause weight loss in patients with obesity-related metabolic disorders and their sequellae. In the United States, about 260,000 bariatric operations are done in each year ( Reference ). Development of safer, minimally invasive approaches has made this surgery more prevalent.
