TI  - Mini/One Anastomosis Gastric Bypass Versus Roux-en-Y Gastric Bypass as a Second 
      Step Procedure After Sleeve Gastrectomy-a Retrospective Cohort Study.

AB  - BACKGROUND: Whether one anastomosis gastric bypass (OAGB) or Roux-en-Y gastric 
      bypass (RYGB) is a better revisional bariatric surgery (RBS) after sleeve 
      gastrectomy (SG) is still under debate. The aim is to compare short-term outcomes 
      of RYGB and OAGB as a RBS after SG, pertaining to their effects on weight loss, 
      resolution of comorbidities, and complications. METHODS: We performed a 
      single-center analysis of 55 patients (n = 34 OAGB, n = 21 RYGB). Indications for 
      revisional surgery included weight regain/loss failure (67%) and intractable 
      gastroesophageal reflux disease (33%). Data were collected up to 1-year follow-up 
      (FU) and included time of revisional surgery, operation time, weight, body mass 
      index, excess weight loss, and total weight loss (TWL), both in percent, 
      complications and resolution of comorbidities. RESULTS: Operation time was 
      79 +/- 36 (OAGB-MGB) and 98 +/- 24 min (RYGB) (p = 0.03). In the first 30 
      postoperative days, three patients in the RYGB group, and no patient in the OAGB 
      group, had postoperative complications. FU was 100%. Minor complication rates at 
      12 months were 33.3% (RYGB) and 35.3% (OAGB). At 12 months, mean % TWL was 
      10.3 +/- 7.6% (RYGB) and 15.8 +/- 7.8% (OAGB) (p = 0.0132). CONCLUSIONS: OAGB after 
      failed SG was found to be a quicker procedure with less perioperative 
      complications. At 1-year FU, no significant differences were seen between RYGB 
      and OAGB regarding readmission and minor complications. Still long-term FU 
      including the risk of malnutrition is needed to have a complete evaluation of 
      OAGB as a RBS for the future.
