Lap Adjustable Gastric Band

The LAP-BAND® System procedure

An additional technique, which has been performed in the US since 2001, is the laparoscopic adjustable gastric band procedure (LAGB). During this procedure, several small incisions are made in the patient's abdomen, and using a laparoscope for guidance, the surgeon places an adjustable band around the upper portion of the stomach. The band is connected to a reservoir, which the surgeon can tighten or loosen, by the infusion of varying amounts of a salt solution. Weight loss occurs because the newly created upper pouch will only allow the patient to consume small amounts of food at a time.

LAGB has been shown to produce short-term weight loss. Since the procedure has only been available since 2001, the effect on long-term weight loss will continue to be monitored. This procedure is less invasive, fewer complications are seen, and patients experience an improvement in obesity related health issues. The surgeon and the patient will determine the type of weight loss surgical procedure that is suitable for each individual.

Complications, which may occur with LAGB surgery, include: The LAP-BAND® System procedure

  • slippage of the band (2-3% of patients)
  • band erosion (1% of patients)
  • port infection (1% of patients)
  • injury to adjacent organs (0.5% of patients)
  • death within 30 days ( < 0.5% of patients)

When looking at the risks associated with weight loss surgery, it is important to remember that obesity itself carries a high risk of mortality due to obesity related illnesses. For many patients the potential risks from not having the surgery may be greater than the risks from possible complications of having the procedure.
