Case report demonstrates successful reintervention for biliary obstruction using cholangioscopy, suggesting a valuable technique.
Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is a valuable alternative for patients for whom endoscopic retrograde cholangiopancreatography (ERCP) is not feasible. However, recurrent biliary obstruction occurs in approximately 19.1–33% of cases, often necessitating reintervention [1] [2]. Herein, we report a case of successful reintervention using peroral cholangioscopy to treat biliary obstruction caused by tissue hyperplasia at the uncovered portion of a self-expandable metallic stent (SEMS) placed during EUS-HGS ([Video 1]).
