Adjustable Gastric Banding

Adjustable gastric bands are prosthetic devices that are laparoscopically placed around the upper part of the stomach.  The band acts as a “govener” to regulate how fast healthy foods flow into the stomach.  Older banding operations (vertical banded gastroplasty) were not adjustable and patients had a great deal of difficulty swallowing healthy food.  By tailoring the tightness of the band (in our Band Evaluation Clinic), you can appropriately control the amount of healthy food you eat at one time.  By reducing the volume and calories of food ingested, patients experience significant weight loss.


The operation is performed laparoscopically with a small camera and light source.  Long skinny instruments are inserted through small incisions (1/4-1/2 inch) are used to perform the operation.  The band is placed around the stomach just below its attachment to the esophagus.  The band has an inflatable bladder that is used to make the band tighter or looser around the stomach thereby controlling the amount of food allowed to pass through the band.

Adjustments are made in our Band Evaluation Clinic at the office.  All adjustments (or “fills”) are made under x-ray guidance allowing more precise filling of the band.  The clinic affords a unique educational opportunity to our band patients because of the immediate visual feedback they get when viewing the adjustment results on the x-ray monitor themselves.

There are two laparoscopic adjustable gastric band systems (Realize Adjustable Gastric Band System and the Lap Band Adjustable Gastric Band System) that are FDA approved and available at the New Life Center for Bariatric Surgery.

Some conditions preclude the insertion of an adjustable gastric band. If the patient has an autoimmune disease, severe heart or lung disease, cirrhosis or severe gastrointestinal disease they are not a candidate for adjustable gastric banding.


Risks specific to adjustable gastric banding include infection, nausea, vomiting, band slipping, band erosion, obstruction and need for future re-operation.


Patients undergo laparoscopic adjustable gastric banding as an outpatient or as a 23 hour hospitalization depending on their health issues.  The post operative pain is typically well managed with oral pain medicine only.  An x-ray study will be performed to evaluate the band and a lower extremity venous ultrasound is routinely obtained to rule out blood clot formation in the legs before discharge.  Most patients can expect to be able to return to office style work in about a week, and unrestricted activity is allowed after one month.

Long term, patients need to follow up regularly in the Band Evaluation Clinic to monitor for band slips and esophageal dysfunction that can occur in some patients.  On average expected excess weight loss is about 40-50% for most patients.

Dr. Stephen Boyce and Dr. K. Robert Williams are very concerned about your long term success.  Our aftercare program is designed with this in mind.  Contact the New Life Center for Bariatric surgery for more information or to schedule a consultation.
