Peroral transhepatic cholangioscopy-guided electrohydraulic lithotripsy via an endoscopic ultrasonography-guided hepaticogastrostomy route for bile duct stones in a patient with Roux-en-Y anatomy.

The article describes the case of an 84-year-old man with bile duct stones, acute cholecystitis, cholangitis, and a history of distal gastrectomy with Roux-en-Y reconstruction.
