[Colonic ileus caused by a giant gallstone].

Gallstone induced colonic ileus is a rare disease. An enormous gallstone was found as the cause of ileus in a previously healthy ninety year-old man. A laparotomy was carried out, and a gallstone measuring 6 x 8 cm was removed from the sigmoideum in a normal looking colon. The stone had been wedged at the ligament of Told after having formed a fistula from the gallbladder to the colon. The fistula was left untouched and the patient was discharged after making a full recovery. A year later the patient developed icterus. Ultrasound examination revealed choledocus stones, which were removed by ERCP papillotomy.
