Hepatic artery protection using a polyglycolic acid sheet during pancreaticoduodenectomy: A multicenter study

Abstract

AbstractBackgroundPostpancreatectomy hemorrhage (PPH) is the most feared complication after pancreaticoduodenectomy (PD). The most common cause is erosion of the gastroduodenal artery stump. Preventive measures have been previously reported, but a consensus is lacking. The aim of this study was to analyze the preventive effect of reinforcing the hepatic artery using a polyglycolic acid (PGA) sheet during PD.MethodsA multicenter retrospective study was performed, collecting data from three tertiary hospitals in Korea. Patients receiving PD from January 2016 to December 2021 were included. The primary endpoint was rate of PPH from the hepatic artery. Arterial reinforcement (AR) was performed by wrapping the artery with Neoveil (Gunze Ltd) and applying fibrin glue. The perioperative data of patients who did not receive AR were compared with data of those who received AR.ResultsA total of 904 patients were analyzed. The rate of PPH from the hepatic artery was significantly lower in the AR group. (3.5% vs 0.7%, p = .002) In patients with CR‐POPF, the 90 day mortality rate of the AR group was less than half that of the non‐AR group (7.2% vs 3.5%, p = .455) Risk factor analysis showed CR‐POPF to be an independent risk factor for PPH. Arterial reinforcement was shown to be a strong protective factor for PPH (OR 0.20, 95% CI: 0.05–0.72, p = .014).ConclusionsAR of the hepatic artery using Neoveil and fibrin glue is a simple method that greatly reduces the rate of PPH after PD.
