The benefit of a LAGB is that it is a minimally invasive procedure that does not require partial removal of the stomach or diversion of the gastrointestinal tract as in gastric sleeve or bypass procedures. However, patients do have to follow up with their surgeon frequently for adjustment of the band. In addition, because this is a restrictive procedure only, patients must maintain a strict diet to avoid inability to lose weight or the possibility of weight gain. Lastly, because general anesthesia is required, this surgery may not be suitable for those deemed high-risk surgical candidates.

Early complications of the lap band are food intolerance and band slippage. Nausea, vomiting, and food intolerance may require removing fluid from the band via the subcutaneous port. Late complications are band erosion, esophageal dilatation, gastric obstruction, and port or tubing problems such as infection. These complications most often lead to hospital admission and frequent reoperation [2].
