BACKGROUND: Revision of bariatric procedures is required in 10 to 25% of patients either for insufficient weight loss or for complications. Patients undergoing vertical banded gastroplasty (VBG; Mason MacLean) may require revision in up to half of the cases in the long term. Roux-en-Y gastric bypass (RYGBP) is considered the procedure of choice for revision of VBG gastroplasty. PATIENTS AND METHODS: Eighteen patients, 16 women and 2 men with a mean age of 41.7 years (range 27-72) and a mean BMI at 37.6 kg/m(2) (range 22.5-47), underwent laparoscopic conversion of VBG into RYGBP. Indications for revisional surgery were insufficient weight loss (11 patients), stoma stenosis (4 patients), and acid reflux (3 patients). RESULTS: Operative time was on average 203 min (range 60-300 min), and conversion was required in one patient (5.5%). There was no early postoperative mortality, and four patients (22.2%) developed immediate postoperative complications (gastrojejunostomy leak 1; stenosis of the gastrojejunal anastomosis 2; liver abscess 1). One patient died 6 months after conversion because of a bleeding anastomotic ulcer (late mortality 5.5%). Two patients (11.5%) developed late complications (incisional hernia 1; internal hernia 1). At a mean follow-up of 23, 4 months BMI is on average 29.8 kg/m(2) (range 22.7-37). CONCLUSION: Although revision of failed VBG into RYGBP gives good functional results, the risk of postoperative serious complications must be carefully evaluated before revision.
