Lessons learned from laparoscopic gastric banding for morbid obesity.

BACKGROUND

Laparoscopic gastric banding is a minimally invasive bariatric operation that is increasing in popularity at many centers worldwide. Although this procedure is not yet approved in the United States, clinical trials are ongoing.

METHODS

We report our results of a 3-year follow-up on 60 patients who underwent the laparoscopic gastric band procedure for the treatment of morbid obesity. The procedure was performed at the Wesley Obesity Clinic in Brisbane, Australia.

RESULTS

At follow-up, 51 of the 60 patients (85%) still had the laparoscopic gastric band in place. All of the patients had a lower body weight after undergoing the procedure. The average weight loss was 39 kg (range 2 to 98 kg), representing a loss of 65% of average excess body weight. Twenty-five of 51 patients (49%) regained some weight after their initial loss, but the average amount was only 5 kg. The remaining 26 patients have remained at their lowest body weight recorded after the procedure or are continuing to lose weight. There was no operative mortality. Complications predominantly were caused by band slippage (21%), which has been nearly eliminated in recent practice (1 slip in the last 225 cases). Subsequent modifications in the technique to prevent band slippage included placing the band near the level of the esophagus, with minimal disruption of the posterior gastric attachments and diligent suturing of the band in place.

CONCLUSIONS

We conclude that the laparoscopic gastric band is effective in short- and long-term weight loss. The high rate of reoperation for repositioning has been avoided in current practice.
