Comparison of Complications and Mortality in Patients Undergoing Laparoscopic Sleeve Gastrectomy With and Without Omentopexy.

Abstract

Background: Among bariatric surgeries, laparoscopic sleeve gastrostomy (LSG) has gained good global acceptance, but this surgery, like any other invasive procedure, has side effects. Various techniques have been tested to reduce these complications, which are used under the title of stapler line reinforcement (SLR). The purpose of this research is to compare the bleeding, leakage, mortality, food intolerance, re-hospitalization, and post-operative invasive therapeutic interventions in LSG surgery in two groups with and without omentopexy method.

Methods: In this retrospective cohort study, the patients who underwent LSG were included in the study and were compared in two groups with omentopexy and without omentopexy in terms of complications. The patients were followed up during the first year after the operation, and the patients were examined in terms of complications, including bleeding, leakage, mortality, food intolerance, re-hospitalization, and post-operative invasive therapeutic interventions.

Results: In terms of bleeding (p = 0.263) and the frequency of leak cases (p = 0.286), no significant difference was observed between the two groups, but the treatment measures performed to control the leak had a significant difference between the two groups (p = 0.013). The need for re-admission was significantly higher (p = 0.017) in the group without omentopexy, and the need for re-surgery was also significantly different (p = 0.001) between the two groups. The frequency of food intolerance was significantly higher (p = 0.001) in the group without omentopexy, and the frequency of mortality was no statistically significant difference with the group with omentopexy (p = 0.304).

Conclusions: The results of this study showed that the need for more aggressive interventions (laparotomy) to control bleeding and leak is less in the group with omentopexy, also the chance of re-hospitalization and re-surgery after omentopexy is reduced, and food intolerance disorder is less in this group. Therefore, the findings of this study show that LSG with omentopexy has fewer side effects than without omentopexy.
