Gastric banding for surgical treatment of morbid obesity has a complication rate of 20 to 50 per cent. Complications include band erosion, band slippage, and failed weight loss. One salvage procedure used is the laparoscopic sleeve gastrectomy. We aimed to compare our results between single-stage and two-stage conversation of gastric band with sleeve gastrectomy. We performed a retrospective review of 27 gastric band patients converted to sleeve gastrectomy. Hospital length of stay, surgical complications, and weight loss were compared. Twelve patients had a two-stage conversion and 15 patients had a single-stage conversion. There were no surgical complications in either group. There was a significant reduction in BMI after conversion, starting at one month and continuing forward to 12 months. The average BMI reduction over the two-year follow-up period was 8.19. There was no significant difference in length of hospital stay between the groups. Single-stage conversion of gastric band to sleeve gastrectomy does not lead to increased hospital length of stay or surgical morbidity. In the presence of gastric band slip or erosion, a two-stage approach is preferable. Conversion resulted in statistically significant weight loss in all patients.
