Gallstone ileus with spontaneous evacuation: A case report

A 65‐year‐old man was referred to our hospital for abdominal pain. He had a history of enterotomy with stone extraction for gallstone ileus. On abdominal computed tomography, a stone measuring 32 × 28 mm lodged in the jejunum was identified. He was diagnosed with gallstone ileus and treated using a nasal ileus tube. Four days after admission, computed tomography showed that the stone had passed into the rectum. The gallstone was spontaneously evacuated on the same day. A fistula with the gallbladder was found in the duodenal bulb. The patient's condition improved, and he was discharged 9 days after admission.
