Laparoscopic Adjustable Gastric Band
The laparoscopic adjustable band is a purely restrictive operation (i.e. there is no malabsorptive component), meaning the weight loss results from patients eating a small volume of food following this operation. In this operation, a silastic ring, or band, is placed around the upper stomach. The size of the band, and the amount of restriction can be adjusted to inflate or deflate the band by injecting or withdrawing fluid via a port implanted in the abdominal wall. Average weight loss following this operation is about 50-55% of excess body weight.
This operation is performed laparoscopically, and requires only one night in the hospital, and in some cases can be performed on an outpatient basis. The band requires frequent visits to the surgeon’s office to adjust the size of the band, which is done based on the patient’s progress. Appropriate candidates for this operation include those who don’t have a large amount of weight to lose and those who are motivated to visit the surgeon’s office on a regular basis for band adjustments.
