Bariatric Surgery: Laparoscopic Adjustable Banding

Bariatric surgery changes the size of your stomach to help you lose weight. The surgery may also prevent your body from absorbing nutrients. The goal is to limit how much food can be eaten and/or absorbed at one time. There are several types of bariatric surgery. You are having laparoscopic adjustable gastric banding (LAGB). This procedure closes off a portion of the stomach to create a very small pouch. This is the most common form of bariatric restrictive surgery.

The Procedure

An adjustable band (like a ring) is placed around the top part of the stomach to create a small pouch of the upper stomach. This pouch holds only a few tablespoons of food. Food passes slowly through a narrow opening created by the band at the bottom of the pouch. So you feel full longer. The size of the band is adjusted using a port placed under the skin. The port gives your doctor a way to insert a needle. The needle is used to add or remove fluid from the band. This is done to make the size of the opening bigger or smaller.  Adjusting the band changes how quickly food leaves the new pouch.

Special Note: The Gallbladder

Bariatric surgery is designed to cause a large amount of weight loss. Weight loss can cause deposits in the gallbladder called gallstones. The gallbladder may be removed during your surgery if you already have gallstones. Or it may need to be removed at a later date.

All types of bariatric surgeries have different advantages and disadvantages. Be sure to discuss the risks and complications of this surgery with your doctor.
