LAP-BAND Surgery

If you are interested in weight-loss surgery, the adjustable gastric band may be an option for you. LAP-BAND surgery restricts the amount of food you can comfortably eat, and it is the only weight-loss surgery that does not permanently alter your gastric tract.

What Is Lap-Band Surgery?

An adjustable gastric band — the LAP-BAND — is similar in size and shape to a napkin ring, measuring about 1½ inches across. The band is connected by thin tubing to a "port," or filling station. The band itself is positioned around the top of the stomach; the port is fixed to the abdominal wall near the belly button and is usually invisible even after weight loss. Your provider accesses the port with a small needle to periodically adjust the band.

How the Band Works

The band works like other restrictive weight-loss operations. When positioned correctly it leaves only a very small pouch of stomach — roughly the size of a walnut — above the band. As food reaches this pouch it pauses there, then slowly passes through a narrow channel about the width of a pinky finger. Once past the band, digestion proceeds normally.

While food waits in the pouch, it gently distends the walls and activates nerves that create the sensation of fullness and satisfaction — allowing you to feel full on a much smaller portion.

How the Band Is Adjusted

Your gastric band will require adjustment periodically for life. Early on, adjustments are more frequent — patients typically return every six weeks or so. Lap-Band surgery usually takes about 30 minutes and most patients go home the same day. The rate of serious complications is the lowest of any bariatric procedure, though revisional adjustments are more common than with other operations. Excess weight loss averages around 45%.

Filling the Band

Adjusting the band is best performed by a skilled "eating coach." The band-adjustment manager — whether doctor, nurse, or PA — matters far more to your weight-loss success than the surgeon who installed the band. Choose a program that offers the ongoing support you need.
