Background There are very few randomised, blinded trials comparing laparoscopic sleeve gastrectomy (LSG) versus laparoscopic Roux-en-Y gastric bypass (LRYGB) in achieving remission of type 2 diabetes (T2D), particularly silastic ring (SR)-LRYGB. We compared the effectiveness of (LSG) versus SR-LRYGB among patients with T2D and morbid obesity. Methods Prospective, randomised, parallel, 2-arm, blinded clinical trial conducted in a single Auckland (New Zealand) centre. Eligible patients aged 20-55 years, T2D of at least 6 months duration and BMI 35-65 kg/m(2) were randomised 1: 1 to LSG (n = 58) or SR-LRYGB (n = 56) using random number codes disclosed after anaesthesia induction. Primary outcome was T2D remission defined by different HbA1c thresholds at 1 year. Secondary outcomes included weight loss, quality of life, anxiety and depressive symptoms, postoperative complications and mortality. Results Mean +/- standard deviation (SD) pre-operative BMI was 42.5 +/- 6.2 kg/m(2), HbA1c 63 +/- 16 mmol/mol (30% insulin-treated, 28% had diabetes duration over 10 years). Proportions achieving HbA1c = 38 mmol/mol, < 42 mmol/mol, < 48 mmol/mol and < 53 mmol/mol without diabetes medication at 1 year in SR-LRYGB vs LSG were 38 vs 43% (p = 0.56), 52 vs 49%(p = 0.85), 75 vs 72%(p = 0.83) and 80 vs 77% (p = 0.82), respectively. Mean +/- SD % total weight loss at 1 year was greater after SR-LRYGB than LSG: 32.2 +/- 7.7 vs 27.1 +/- 7.5%, respectively (p < 0.001). Gastrointestinal complications were more frequent after SR-LRYGB (including 3 ulcers, 1 anastomotic leak, 1 abdominal bleeding). Quality of life and depression symptoms improved significantly in both groups. Conclusion Despite significantly greater weight loss after SR-LRYGB, there was similar T2D remission and psychosocial improvement after LSG and SR-LRYGB at 1 year.
