Introduction: Conversion to laparoscopic gastric bypass (LRYGB) appears to be the treatment of choice after failed LAGB. To reduce the risk of postoperative complications, some surgeons routinely adopt a two-stage strategy. The purpose of this study was to analyze our institution's experience with the two-stage procedure for LAGB conversion to LRYGB MATERIALS AND METHODS: The bariatric database of our institution was reviewed to identify patients who had undergone conversion of LAGB to LRYGB from November 2007 to June 2012.
Results: One hundred patients were included. Of these, 62 (62%) required conversion to LRYGB for inadequate weight loss or weight regain and 38 for band-related complications. All the procedures were performed in two stages and laparoscopically. The average time between band removal and LRYGB was 17.3 months. The mean follow-up after LRYGB was 31 ± 18.7 months. The mean BMI prior to LRYGB conversion was 45.3 ± 5.2. Early complications occurred in 15 patients (15%), while late complications occurred in only 3 patients (3%). The average %EWL at 24 months and 48 months after conversion was 70.1 and 69.4%, respectively.
Conclusion: Although a two-stage conversion strategy increases the number of operations and hospital stay without decreasing the rate of early complications compared to one-stage conversion; it has shown to be associated with low rates of GJA stenosis and excellent %EWL.
