Abstract Aim Sleeve Gastrectomy, is a widely used procedure globally. However, omentopexy is a newly added variation, which involves reattachment of the omental to the stomach. Currently, there is not enough data regarding this technique, so this study evaluates the impact of omentopexy in Laparoscopic Sleeve Gastrectomy on intra-operative time and complications within one year of follow-up. Method A prospective cohort study was conducted from June 2021 to June 2023 in Ain Shams University Hospitals and other non-government hospitals, which included 174 for a one-year follow-up. Results In our study 87 patients in each group. Both groups underwent Laparoscopic Sleeve Gastrectomy, Group (I) with omentopexy while Group (II) without omentopexy. Regarding intra-operative time, the mean time in minutes in the group (I) is 115.45 minutes with a standard deviation ±11.19. While in group (II) is 79.8 minutes with a standard deviation of ±13.3 (p=O.001). Regarding complications rate within one year. leakage occurred in 1(1.14%) patient in group (I). While, in 3(3.4%) patients in group (II) (p=0.62). Bleeding was found in 1 (1.1%) patient in group(I) and 2(2.3%) patients in group (II) (p=1). GERD was found in 10(11.49%) patients in group(I) and 12(13.7%) patients in group (II) (p=0.82). Conclusions Omentopexy with LSG has shown to be a successful merging technique in terms of decreasing the rate of leakage and bleeding, although it appears to require more operative time, further refinement of the learning curve is possible to further reduce operative time.
