- Abstract
Background: Ten to 50% of patients who received restrictive bariatric operations may require reoperation for unsatisfactory weight loss or weight regain. Failed restrictive procedures are usually managed with conversion to another bariatric procedure with a favor of conversion to laparoscopic gastric bypass. Our aim is to evaluate two different bypass techniques, laparoscopic RY gastric bypass (RYGB) versus single-anastomosis (mini-) gastric bypass (SAGB) as a revision option (R-RYGB and R-SAGB) for failed restrictive bariatric operations.Material and Methods: From May 2001 to December 2015, a total of 116 patients with failed restrictive bariatric operations underwent laparoscopic revisional bypass surgery (81 R-SAGB and 35 R-RYGB). Among them, 81 were failed after vertical banded gastroplasty (VBG) and 35 were after adjustable gastric band (AGB). The demographic data, surgical parameters, and outcomes were studied.Results: The average age at revision surgery was 35.7 years (range 22-56), and the average body mass index (BMI) before reoperation was 37.2 kg/m2 (29.0-51.8). Revision surgery was performed after 58.8 months from the primary surgery on average (14-180 months). The main reasons for the revisions were weight regain (50.9%), inadequate weight loss (31%), and intolerance (18.1%). All of the procedures were completed laparoscopically as one-stage procedure. R-RYGB had significantly longer operative times than R-SAGB. Major complication occurred in 12 (10%) patients without significant difference between R-SAGB group and R-RYGB group. At 1 year follow-up, weight loss was better in R-SAGB than R-RYGB (76.8 vs. 32.9% EWL; <italic>p</italic> = 0.001). At 5 year follow-up, a significantly lower hemoglobin level was found in R-SAGB group (<italic>p</italic> = 0.03).Conclusion: Both SAGB and RYGB are acceptable options for revising a restrictive type of bariatric procedures with equal safety profile. R-SAGB was shown to be a simpler procedure with better weight reduction than R-RYGB but anemia is a considerable complication at long-term follow-up.
