Evolution of the laparoscopic gastric bypass

Obesity is recognized as a health problem of epidemic proportions. Surgical intervention for the treatment of obesity is a well-studied and effective method. Various procedures have been utilized over the past decades. Roux-en-Y gastric bypass has emerged over the last 20 years and is currently the most commonly offered surgical treatment. Within the last decade, advances in laparoscopic technology and surgical experience have allowed the application of laparoscopic techniqes to the surgical treatment of obesity. Many centers and indiviuals have developed excellent techniques through experience over time as well as improvements in instrumentation. Hand-assisted laparoscopy was reported as a technique, but has mostly fallen out of favor. Currently, laparoscopic application of adjustable gastric band and laparoscopic Roux-en-Y gastric bypass are widely used throughout the United States. Data have been generated to demonstrate the improvement in surgical outcomes associated with minimally invasive surgical techniques for the surgical treatment of obesity. Further advances will allow continued improvement in patient outcomes utilizing a variety of minimally invasive surgical approaches to the treatment of this difficult disease.
