OBJECTIVE: When restrictive surgery fails. conversion to more malabsorptive techniques is frequently proposed. The aim of this study is to evaluate the weight loss figures between Roux-en-Y Gastric Bypass (RYGB) and One Anastomosis Gastric Bypass (OAGB) in patients who have already undergone Multiple Restrictive Procedures (MRP).PATIENTS AND METHODS: All patients who underwent conversion of Laparoscopic Sleeve Gastrectomy (LSG) to RYGB or OAGB between 2010 and 2019 were retrospectively analyzed. Only patients who had conversion for Weight Regain (WR) or Insufficient Weight Loss (ML) after both Laparoscopic Gastric Banding (LGB) and LSG entered the study population. Finally, 44 patients underwent conversion to RYGB, and 24 patients to OAGB.RESULTS: Concerning Excess Weight Loss (%EWL) at 3, 6, 12, 24 postoperative months, the results for RYGB were 33.7%. 47.95%. 61.8%, 61.8%, while for OAGB were 38.3%, 51.9%. 63.75%. 79.45%. A significant difference was recorded in favor of OAGB at 3 (p=0.03) and 24 (p=0.046) postoperative months. % EWL at 24 months in the case of IWL was 57.8% for RYGB, while for OAGB was 72.7% (p=0.047). No significant difference was found considering patients with WR (80.9% and 80.5%; p= 0.999). Patients with better results at 24 months after surgery had a significantly longer time between sleeve and bypass than those with a lower % EWL.CONCLUSIONS: The results of the present study seem to show that both techniques give good results at 24 months in patients who have undergone MRP. However, OAGB shows overall better results. particularly in patients with IWL.

Abstract

OBJECTIVE: When restrictive surgery fails. conversion to more malabsorptive techniques is frequently proposed. The aim of this study is to evaluate the weight loss figures between Roux-en-Y Gastric Bypass (RYGB) and One Anastomosis Gastric Bypass (OAGB) in patients who have already undergone Multiple Restrictive Procedures (MRP).PATIENTS AND METHODS: All patients who underwent conversion of Laparoscopic Sleeve Gastrectomy (LSG) to RYGB or OAGB between 2010 and 2019 were retrospectively analyzed. Only patients who had conversion for Weight Regain (WR) or Insufficient Weight Loss (ML) after both Laparoscopic Gastric Banding (LGB) and LSG entered the study population. Finally, 44 patients underwent conversion to RYGB, and 24 patients to OAGB.RESULTS: Concerning Excess Weight Loss (%EWL) at 3, 6, 12, 24 postoperative months, the results for RYGB were 33.7%. 47.95%. 61.8%, 61.8%, while for OAGB were 38.3%, 51.9%. 63.75%. 79.45%. A significant difference was recorded in favor of OAGB at 3 (p=0.03) and 24 (p=0.046) postoperative months. % EWL at 24 months in the case of IWL was 57.8% for RYGB, while for OAGB was 72.7% (p=0.047). No significant difference was found considering patients with WR (80.9% and 80.5%; p= 0.999). Patients with better results at 24 months after surgery had a significantly longer time between sleeve and bypass than those with a lower % EWL.CONCLUSIONS: The results of the present study seem to show that both techniques give good results at 24 months in patients who have undergone MRP. However, OAGB shows overall better results. particularly in patients with IWL.
