Intrahepatic biliary stones extraction via an EUS‐guided hepaticogastrostomy route confirmed by peroral transluminal video cholangioscopy (with video)

Endoscopic ultrasonography (EUS)-guided bile duct stone (BDS) treatment has been developed for patients with duodenal obstruction, biliary stricture, or surgically altered anatomy. Recently, peroral transluminal video cholangioscopy (POTVCS)-guided BDS treatment via the EUS-guided biliary drainage route has been reported [1-5]. Here, we present a successful case of intrahepatic BDS extraction via the EUS-guided hepaticogastrostomy (EUS-HGS) route confirmed under direct antegrade POTVCS.
