摘要
Background: Endoscopic biliary drainage is the treatment of choice for patients with malignant distal common bile duct obstruction. Self-expandable metal stents have clinical advantages including an in-creased duration of patency that may be prolonged by acetylsalicylic acid (ASA) use. The aim of this study was to investigate whether ASA had a positive effect on the patency of self-expandable metal stents compared with placebo.Methods: This prospective, multicenter, double-blinded, and randomized placebo-controlled trial was conducted from October 2017 to May 2020 in Korea. Patients who underwent palliative endoscopic bil-iary drainage with self-expandable metal stents for malignant distal bile duct obstruction were enrolled, and allocated to ASA treatment or placebo. The study outcomes were the rate of stent dysfunction at 6 months, duration of stent patency, risk factors for stent dysfunction, and any adverse events.Results: Interim analysis included 24 and 28 patients in the ASA and placebo groups, respectively. There was no significant difference between the ASA and placebo groups in stent dysfunction (25.0% vs. 20.7%, P = 0.761) or the duration of stent patency (150.97 +/- 10.55 vs. 158.07 +/- 8.70 days, P = 0.497). Six patients experienced suspected ASA-related adverse events, and there was one lethal case. Conclusions: ASA did not prolong stent patency. This study was terminated early because of the possibil-ity of serious adverse events related to ASA treatment of these patients receiving palliative care.(c) 2021 First Affiliated Hospital, Zhejiang University School of Medicine in China.
