BACKGROUND: The LAP-BAND is designed to be an adjustable laparoscopically placed gastric restriction device for the treatment of severe obesity. The purpose of this study was to assess the outcome in patients who had failed to effectively lose weight with this device and were converted to a gastric bypass. METHODS: A retrospective chart review was performed of all LAP-BANDS placed in patients at our institution from March 1996 to June 1998. RESULTS: 36 LAP-BANDS were placed. To date, 18 of 36 (50%) have been removed. Fourteen of 18 were simultaneously converted to a gastric bypass. Indications for conversion included: failed weight loss (5), failed weight loss with esophageal dilatation (5), failed weight loss with leaking band (2), and symptomatic esophageal dilatation (1). Median time to conversion after LAP-BAND placement was 38.2 months. Median follow-up after conversion to gastric bypass was 8.3 months. Nineteen percent excess weight loss occurred after LAP-BAND placement. Forty-three percent excess weight loss occurred after conversion to gastric bypass (P =.025). CONCLUSIONS: In our experience, the LAP-BAND is associated with a high frequency of inadequate weight loss. Conversion to gastric bypass in this subset of patients is technically challenging but results in superior weight loss in a shorter time period.
