Surgical options for obesity
Bariatric surgery dates to the 1950s when intestinal bypass was first performed. The total weight lost correlates with the total length of bowel bypassed. Gastric bypass (GBP) is the most common weight loss surgery performed in the United States.
The laparoscopic adjustable gastric banding procedure is the most common bariatric surgery in Australia and Europe.
A recent systematic review concluded that weight loss outcomes strongly favored Roux-en-Y GBP over laparoscopic adjustable gastric banding.
