The patient was a 100-year-old woman. She was admitted because of cholangitis by common bile duct stones (CBDs) at the age of 93 years. Endoscopic retrograde cholangiopancreatography (ERCP) revealed multiple CBDs, and we placed a plastic biliary stent (PS) for CBD. She complained of lower abdominal pain a year after she discharged and computed tomography (CT) revealed PS in the sigmoid colon. We removed it by colonoscopy and placed PS again for CBD. She was admitted because of acute cholangitis 2 years later. ERCP showed migration of PS. We could not remove that by a basket catheter and balloon catheter but successfully removed it using grasping forceps. Finally, we placed two PSs for CBD, and they are under observation for more than 3 years. A long-term PS placement is useful in very elderly patients with choledocholithiasis, but it is necessary to pay attention to stent dislodgement and migration.
