We report a case of hepatolithiasis 30 years after congenital biliary dilatation (CBD) surgery. A 31‐year‐old woman presented with fever and epigastric pain. She had a history of radical surgery for type I CBD at the age of 1 year and had no significant symptoms for approximately 30 years after surgery. Laboratory and imaging results showed hepatolithiasis at the common trunk of segments II and III with cholangitis. She was admitted to our hospital for antibiotics and underwent double‐balloon endoscopic retrograde cholangiography (DBERC) to treat the hepatolithiasis. Roux‐limb jejunum was perforated during DBERC; hence, emergent laparoscopic perforation site closure and simultaneous endoscopic lithotomy through the Roux‐limb jejunum with exteriorization via umbilical incision were performed. The postoperative course was uneventful, and the patient was discharged without any complications.
