title: Laparoscopic Roux-en-Y gastric bypass versus laparoscopic adjustable gastric banding in the super-obese: peri-operative and early outcomes.
abstract: BACKGROUND
  Controversy exists between laparoscopic Roux-en-Y gastric bypass and laparoscopic adjustable gastric banding in super-obese patients.
  
  
  METHODS
  This is a retrospective review of prospectively collected data. A total of 102 consecutive super-obese (body mass index >50) patients underwent laparoscopic Roux-en-Y gastric bypass (Group 1), and 79 consecutive ones underwent laparoscopic adjustable gastric banding (Group 2). Early complications and weight loss outcomes were evaluated.
  
  
  RESULTS
  No significant difference was found in operative mean (± standard deviation) time (93.5 ± 33 vs 87.7 ± 39 min, p = 0.29), hospital stay (2.68 ± 2.27 vs 2.75 ± 1.84 days, p = 0.80), or overall early postoperative morbidity (17.65% and 10.12%, p = 0.20). Intra-operative complications occurred in six patients (5.9%) in Group 1 and none in Group 2 (0.0%, p = 0.04). Mean excess weight loss percent at 6 and 12 months in Group 1 was 44.75% ± 11.84% and 54.71% ± 18.18% versus 26.20% ± 12.42% and 31.55% ± 19.79% in Group 2 (p < 0.001).
  
  
  CONCLUSIONS
  There seems to be no significant differences in early complications between laparoscopic Roux-en-Y gastric bypass and laparoscopic adjustable gastric banding operations in the short term. Weight loss and excess weight loss percent at 6 and 12 months are significantly better after laparoscopic Roux-en-Y gastric bypass.
