Topical hemostatic application on staple line in laparoscopic sleeve gastrectomy: a single-surgeon experience.

Abstract

Laparoscopic sleeve gastrectomy (LSG) is a common bariatric procedure with low complication rates. Several hemostatic agents have been used to reduce staple line bleeding, but its impact is unclear. The primary endpoint of this study was to compare the early (30-day) complications comparing oxidized regenerated cellulose (ORC) and fibrin sealant (FS) application on the staple line. The secondary endpoints were to compare the need for postoperative blood transfusion, postoperative blood work values of hemoglobin (Hb), white blood cell (WBC), C-reactive protein (CRP), drain output volume and hospital length of stay (LOS). A retrospective analysis of all patients who underwent LSG between January and October 2021 was performed. Subjects were divided into two groups according to the use of ORC versus FS on the staple line. Early postoperative complications, Hb level, WBC count, and drain output volume were compared between groups. A total number of 77 patients were included: 27 in the ORC-group and 50 in the FS-group. No major complication was recorded in both groups. There was no significant difference in the need for blood transfusion, Hb value, and drain output volume on postoperative day (POD) 1 and 2. There was a significantly higher WBC count in the ORC-group on POD 1 and 2. There was no difference in hospital LOS between the groups. The use of FS and ORC was associated with a comparable low rate of bleeding. ORC causes an increased WBC count postoperatively, but this showed no clinical relevance.
