BACKGROUND: The aim of this study was to investigate the long-term impact of the type of preoperative biliary drainage used for patients undergoing pancreatoduodenectomy for distal cholangiocarcinoma (DCC). METHODS: A total of 84 patients with DCC who underwent preoperative biliary drainage between June 2000 and December 2016 were divided into groups for whom percutaneous transhepatic biliary drainage (PTBD) (n = 24) or endoscopic biliary drainage (EBD) (n = 60) was used. RESULTS: The 5-year overall survival in the PTBD group was significantly worse than that in the EBD group (16.7% versus 52.3%, P = 0.007). After propensity score matching (22 patients in each group), the 5-year overall survival in the PTBD group was still worse than that in the EBD group (13.6% versus 61.2%, P = 0.003). Multivariate analysis revealed that PTBD was independent risk factor for both poor survival (P = 0.028) and peritoneal recurrence (P = 0.018). The incidence of multiple sites at initial recurrence tended to be higher in the PTBD group than in the EBD group (P = 0.080). CONCLUSIONS: PTBD should not be performed for patients undergoing pancreatoduodenectomy for DCC, except when EBD is contraindicated, as PTBD is significantly associated with shorter survival and peritoneal recurrence.
