Bioabsorbable Glycolide Copolymer is Effective in Reducing Staple Line Bleeding in Sleeve Gastrectomy

Abstract

Background: Postoperative bleeding from the staple line after sleeve gastrectomy occurs in 2-8% of patients and it is associated with increased length and cost of hospitalization and may demand reoperation to gain hemostasis. Reinforced staplers are used by bariatric surgeons to reduce the incidence of postoperative leak but can have a role in avoiding bleeding. The aim of this study is to analyze the effects of reinforcement on the whole gastric staple line during sleeve gastrectomy on postoperative bleeding.

Methods: Four hundred forty-eight consecutive patients undergoing sleeve gastrectomy from November 2012 to April 2019 were divided into two groups. In the Top-only group only the top staple shot was realized with reinforced material (GORE® SEAMGUARD®) while in the Bottom-to-Top group, patients received full staple line reinforcement. Statistical analysis focused on postoperative leak and bleeding, and length of stay; a propensity score matching analysis was performed to reduce between-group characteristics imbalance.

Results: One hundred forty-five (Top-only) and 303 (Bottom-to-Top) patients were included. Four (2.8%) patients in the Top-only group and none in the Bottom-to-Top group experienced severe bleeding (p = 0.004); the difference was still significant after propensity score matching. Length of stay was significantly shorter for the Bottom-to-Top group before and after propensity score matching (4 vs. 5 days, p < 0.001).

Conclusions: Staple line buttressing reduces the incidence of severe postoperative bleeding when performed on the whole staple line, and it is associated with a shorter hospitalization.
