Résumé
Although different procedures have been proposed as revisional surgery for patients who had previously undergone a failed primary restrictive procedure, the ideal revisional procedure is still a matter of debate. A systematic search was performed in all electronic databases to find studies comparing one anastomosis-mini gastric bypass (OAGB-MGB) or Roux-en-Y gastric bypass (RYGB) as revisional bariatric surgery for weight regain or intolerance/complications of a primary restrictive procedure. The data regarding sample size, patients' gender, age, primary surgery type, number of perioperative complications, operative time, pre- and post-revisional body mass index (BMI), and excess weight loss % (EWL%) at 1-year follow-up were extracted. Five studies were included in the analysis. The primary bariatric procedures were represented by vertical banded gastroplasty (VBG), laparoscopic adjustable gastric band (LAGB) and laparoscopic sleeve gastrectomy (LSG). About perioperative complications, both RYGB and OAGB-MGB showed a similar rate of leaks but OAGB-MGB had a lower rate of bleedings; considering the progression from pre- to post-revisional BMI, OAGB-MGB reveals a better outcome as well as a shorter operative time. Our meta-analysis has shown OAGB-MGB, used as revisional intervention after failed restrictive surgery, achieves outcomes comparable to RYGB in terms of perioperative complications providing a simpler and more effective technique.

BACKGROUND
BACKGROUND
Although different procedures have been proposed as revisional surgery for patients who had previously undergone a failed primary restrictive procedure, the ideal revisional procedure is still a matter of debate.
METHODS
METHODS
A systematic search was performed in all electronic databases to find studies comparing one anastomosis-mini gastric bypass (OAGB-MGB) or Roux-en-Y gastric bypass (RYGB) as revisional bariatric surgery for weight regain or intolerance/complications of a primary restrictive procedure. The data regarding sample size, patients' gender, age, primary surgery type, number of perioperative complications, operative time, pre- and post-revisional body mass index (BMI), and excess weight loss % (EWL%) at 1-year follow-up were extracted. Five studies were included in the analysis.
RESULTS
RESULTS
The primary bariatric procedures were represented by vertical banded gastroplasty (VBG), laparoscopic adjustable gastric band (LAGB) and laparoscopic sleeve gastrectomy (LSG). About perioperative complications, both RYGB and OAGB-MGB showed a similar rate of leaks but OAGB-MGB had a lower rate of bleedings; considering the progression from pre- to post-revisional BMI, OAGB-MGB reveals a better outcome as well as a shorter operative time.
CONCLUSIONS
CONCLUSIONS
Our meta-analysis has shown OAGB-MGB, used as revisional intervention after failed restrictive surgery, achieves outcomes comparable to RYGB in terms of perioperative complications providing a simpler and more effective technique.
