Covering reinforced staples with polyethylene glycolic acid felt-covered fibrin sealant to prevent pancreatic fistula after distal pancreatomy: a retrospective comparative study

Abstract

Abstract Background In accordance with previous reports on the utility of polyethylene glycolic acid (PGA) felt and fibrin glue for postoperative pancreatic fistula (POPF), we usually perform distal pancreatectomy (DP) with a PGA felt reinforcement stapler when dissecting the pancreas and cover the stump with PGA felt and fibrin glue (the PPF method). In this study, we retrospectively analyzed our DP cases to compare the risk factors for POPF and the postoperative course of patients receiving the PPF method of treatment versus that of those receiving conventional treatment. Methods A total of 127 DP procedures performed in our department between January 2008 and June 2021 were retrospectively analysed. Results In the PPF method, grade B/C POPF rate tended to decrease, and POPF rate showed a significant decrease. The duration of drainage and the length of postoperative hospitalisation were also significantly shorter with the PPF method. The risk of grade B/C POPF significantly decreased with the PPF method if the pancreas was thick (> 13.5 mm) or the patients were obese. Conclusions The PPF method is useful for POPF in DP and is particularly effective when a thick pancreas or obese patient is involved. Removing the drainage tube early in the PPF method may lead to early discharge.
