Background Few studies have focused on the risk factors for dysfunction of endoscopic biliary drainage (EBD) in preoperative patients with malignant hilar biliary obstruction (MHBO). Methods We searched the database between February 2011 and December 2018 and identified patients with MHBO who underwent radical operation. The rate of dysfunction of the initial EBD, risk factors for dysfunction of the initial EBD and survival after surgery were retrospectively evaluated. Results We analyzed a total of 131 patients [95 males (72.5%); mean age, 69.5 (±7.3) years; Bismuth‐Corlette classification (BC) I/II/IIIa/IIIb/IV, 50/26/22/17/16; hilar cholangiocarcinoma/gall bladder cancer, 115/16]. Dysfunction of the initial EBD occurred in 28 patients (21.4%). The cumulative incidences of dysfunction of the initial EBD in all patients were 18.4%, 38.2% and 47.0% at 30, 60 and 90 days, respectively (Kaplan–Meier method). The rate of dysfunction of the initial EBD increased in patients with BC‐IV ( P = .03). Multivariate analysis showed that BC‐IV and pre‐EBD cholangitis were significantly associated with the occurrence of dysfunction of the initial EBD. Survival rates were not significantly different according to the initial biliary drainage methods and presence/absence of the initial EBD dysfunction. Conclusions Dysfunction of the initial EBD frequently occurs in patients with the BC‐IV and those with pre‐EBD cholangitis.
