To evaluate risk factors for adverse events and long-term outcomes of EUS-BDS.
Prospective follow-up study.
Tertiary-care academic center.
This study involved 57 consecutive patients with malignant or benign biliary obstruction undergoing EUS-BDS after failed ERCP.
EUS-guided hepaticogastrostomy (EUS-HGS) and EUS-guided choledochoduodenostomy with transluminal stenting (EUS-CDS).
Risk factors for postprocedure and late adverse events and clinical outcomes of EUS-BDS.
The overall technical and functional success rates, respectively, in the EUS-BDS group were 96.5 % (intention-to-treat, n = 55/57) and 89 % (per-protocol, n = 49/55). Postprocedure adverse events developed after EUS-BDS in 11 patients (20 % , n = 11/55). This included bile peritonitis (n = 2), mild bleeding (n = 2), and self-limited pneumoperitoneum (n = 7). In multivariate analysis, needle-knife use was the single risk factor for postprocedure adverse events after EUS-BDS (odds ratio 12.4; P = .01). A late adverse event in EUS-BDS was distal stent migration (7 % , n = 4/55). The mean stent patencies with EUS-HGS and EUS-CDS were 132 days and 152 days, respectively.
Single-operator performed, nonrandomized study.
EUS-HGS and EUS-CDS may be relatively safe and can be used as an alternative to PTBD after failed ERCP. Both techniques offer durable and comparable stent patency. The use of a needle-knife for fistula dilation in EUS-BDS should be avoided if possible.
