PG - 776-786 LID - S0016-5107(23)02703-7 [pii] LID - 10.1016/j.gie.2023.06.053 [doi] AB - BACKGROUND AND AIMS: Intraductal plastic stent (IS) placement for unresectable malignant hilar biliary obstruction (UMHBO) is an effective option for biliary drainage. However, the effectiveness of bilateral IS placement compared with bilateral self-expandable metal stent (SEMS) placement remains unclear. METHODS: Overall, 301 patients with UMHBO were enrolled; 38 patients underwent bilateral IS placement (IS group) and 38 patients underwent SEMS placement (SEMS group) in the propensity score-based cohort. Both groups were compared for technical and clinical success, adverse events (AEs), recurrent biliary obstruction (RBO), time to RBO (TRBO), overall survival (OS), and endoscopic reintervention (ERI). RESULTS: No significant differences were observed between the groups regarding technical and clinical success, AEs and RBO occurrence rates, TRBO, or OS. The median initial endoscopic procedure time was significantly shorter in the IS group (23 vs 49 minutes, P < .01). ERI was performed on 20 and 19 patients in the IS and SEMS groups, respectively. The median ERI procedure time was significantly shorter in the IS group (22 vs 35 minutes, P = .04). Median TRBO after ERI with plastic stent placement tended to be longer in the IS group (306 vs 56 days, P = .068). A Cox multivariate analysis showed that the IS group was the significant related factor for TRBO after ERI (hazard ratio, .31; 95% confidence interval, .25-.82; P = .035). CONCLUSIONS: Bilateral IS placement can reduce the duration of the endoscopic procedure and provide sufficient stent patency both initially and after ERI stent placement, and the stents are removable. Bilateral IS placement is considered a good option for initial UMHBO drainage. (Clinical trial registration number: UMIN000050546.).
