BACKGROUND: The most common bariatric operation in Europe, laparoscopic adjustable gastric banding (LAGB), is reported to have a high incidence of long-term complications. Also, insufficient weight loss is reported. The optimal conversion technique is unknown. Our objective was to report our experience in the conversions of failed laparoscopic gastric banding procedures to 4 different bariatric procedures at a university hospital.

METHODS: From March 2006 to December 2010, 630 bariatric operations were performed. Of these patients, 45 underwent conversion of failed LAGB (n = 38) and nonadjustable gastric banding (n = 7). Using a prospectively collected database, we analyzed these procedures.

RESULTS: The 45 patients underwent laparoscopic conversion of failed LAGB (n = 38) and nonadjustable gastric banding (n = 7) to 4 different procedures. Of the 45 patients, 18 underwent conversion to laparoscopic sleeve gastrectomy, 18 to laparoscopic Roux-en-Y gastric bypass, 7 to laparoscopic biliopancreatic diversion with duodenal switch, and 2 to laparoscopic biliopancreatic diversion. All conversions but 1 were completed laparoscopically. The mean operating time and hospital stay for laparoscopic sleeve gastrectomy, laparoscopic Roux-en-Y gastric bypass, laparoscopic biliopancreatic diversion with duodenal switch, and biliopancreatic diversion was 111 ± 28 minutes and 4.3 ± 1.4 days, 195 ± 59 minutes and 3.9 ± 1.5 days, 248 ± 113 minutes, and 5.9 ± 2.6 days, and 203 minutes and 6.5 days, respectively. No patient died. Perioperative complications occurred in 4 patients (9.8%). The mean body mass index decreased from 41.5 ± 8 kg/m(2) to 31.3 ± 6.8 kg/m(2) during a mean follow-up period of 13.7 ± 9.6 months. Although laparoscopic biliopancreatic diversion with and without duodenal switch had the greatest preoperative body mass index, they achieved the greatest excess weight loss.

CONCLUSION: Conversion of LAGB or nonadjustable gastric banding to laparoscopic sleeve gastrectomy, laparoscopic Roux-en-Y gastric bypass, and laparoscopic biliopancreatic diversion with or without duodenal switch is feasible and effective to treat the complications of LAGB and to further reduce the weight of morbidly obese patients.
