The laparoscopic adjustable band was first introduced in Europe 10 years ago. It was approved in the United States in 2001. This is a purely restrictive procedure, which limits only the amount of food that can be eaten. The pouch size is 15-25cm.
The expected excess body weight loss is approximately 50-55%. The possible problems include slippage, band erosion, infection, connecting system failure, leaks, port rotation, etc.
