BACKGROUND: Percutaneous transhepatic biliary drainage (PTBD) may be the last resort for an occluded biliary metal stent when the ERCP was unsuccessful. OBJECTIVE: Because an EUS-guided biliary drainage has been proposed as an effective alternative for PTBD after a failed ERCP, we conducted this study to determine the feasibility and usefulness of an EUS-guided hepaticogastrostomy (EUS-HG) with a fully covered self-expandable metal stent (FCSEMS) for an occluded biliary metal stent after a failed ERCP. DESIGN: A case study. SETTING: A tertiary referral center. PATIENTS AND INTERVENTIONS: Five patients who had an occluded biliary metal stent inserted after a hilar bilateral metal stent or a combined duodenal and biliary metal stent insertion and for whom reinterventional ERCP was unsuccessful underwent an EUS-HG with an FCSEMS for alternative PTBD. MAIN OUTCOME MEASUREMENTS: Technical and functional success, procedural complications, reinterventional rate after EUS-HG with an FCSEMS, and short-term stent patency. RESULTS: In all 5 patients, an EUS-HG with an FCSEMS was technically successful. No procedural complications, such as bile peritonitis, cholangitis, and pneumoperitoneum, were observed. Functional success was also 100% (5/5). During the follow-up period (median 152 days, range 64-184 days), no late complications, such as stent migration and occlusion, were observed. Thus, no biliary reintervention was performed during the follow-up period. LIMITATIONS: A small series of patients without a control group. CONCLUSIONS: The EUS-HG with an FCSEMS may be feasible, effective, and an alternative PTBD for an occluded biliary metal stent after a failed ERCP.
