Short‑Term Outcomes of Double Omentopexy in One Anastomosis Gastric Bypass Surgery: A Controlled Clinical Trial

Abstract

Purpose: This study aims to assess the efficacy of implementing a novel technique of reinforcement of gastric pouch and remnant  stomach staple line with Double Omentopexy (DO) in patients undergoing One‑Anastomosis Gastric Bypass (OAGB) surgery and evaluate  its impact in reducing the early postoperative complications.

Materials and Methods: The 123 patients were allocated into two  groups: 61 in the standard OAGB group and 62 in OAGB with DO group. The primary outcomes are postoperative complications  (including early postoperative bleeding, leakage, gastric twist, reflux, etc.) and hospital stay. The secondary outcome is excess body  weight loss. Follow‑up visits were planned after discharge: at two weeks, two months, and three months postoperatively. 

Results:  Postoperative complications were significantly lower, 3 (4.84%) in OAGB with DO compared with 10 (16.39%) in standard OAGB (P =0.037).  There was no statistically significant difference in the incidence of early postoperative bleeding, deep vein thrombosis, biliary  reflux, and gall bladder stone (P >.05). No patient had leakage in either group. The mean operative time was significantly longer (68.66 ±  6.68 min) in OAGB with the DO group when compared with the standard OAGB group (62.16 ± 7.54 min) (P <.001).

Conclusion: Applying  the DO technique may be a good measure to be added during OAGB to decrease the incidence of potential postoperative complications,  especially the rate and severity of bleeding.
