A man in his 60s visited the emergency department after developing left lower-quadrant pain that day (Day X) . A biliary stent had been placed 4 years earlier for stacked common bile duct stones, and he had been followed-up as an outpatient. Ileus was diagnosed, and he was admitted the same day. CT on Day X revealed dilation of the presence of stacked common bile duct stones and a migrated biliary stent at the tip of the jejunum. The biliary stent was retrieved on Day X＋20 by single-balloon enteroscopy via an oral approach. Following stent retrieval, a large stone was found on the side of the anus. The patient developed abdominal distension on Day X＋21, and CT on Day X＋24 revealed ileus caused by the stones. Laparotomy was performed to resolve the ileus and remove the common bile duct stones.
