Comparison of Early Postoperative Outcomes of Omentopexy and Clips along the Staple Line During Laparoscopic Sleeve Gastrectomy: A Randomized Study.

Background: We aimed to compare the omentopexy and clipping reinforcement methods performed along the staple line during laparoscopic sleeve gastrectomy (LSG) in terms of the effectiveness on postoperative bleeding.

Methods: In this prospective randomized controlled study, patients were divided into two groups: clips group (CG) and omentopexy group (OG). The groups were compared in terms of postoperative bleeding, duration of surgery, length of hospital stay, hospital readmissions in the postoperative first 30-days.

Results: A total of 148 patients were included in the study. Postoperative bleeding was observed in 11 patients (14.9%) of CG and 2 patients (2.7%) of the OG, and the difference between the groups was found to be significant (p = 0.009). Similarly, the number of patients with bleeding that did not require intervention was 9 (12.2%) in CG and 2 (2.7%) in OG, and the difference between the groups was also significant (p = 0.028). The duration of surgery in the CG was 30 (27 to 36) minutes, whereas in the OG, it was 43 (39 to 45) minutes, with a significant difference noted (p < 0.001). Additionally, the rate of patients readmitted to the hospital within the first 30 days was 16 (21.6%) in the CG and 7 (9.5%) in the OG, with a significant difference observed (p = 0.041).

Conclusion: In terms of bleeding requiring intervention, there was no difference between omentopexy and clipping techniques. In addition, omentopexy showed more satisfactory results than clipping in terms of non-interventional bleeding, but its clinical significance is unclear.
