text: [Unusual form of ileus, except in elderly patients?].
  Two women aged 88 and 92, recently admitted to hospital, were diagnosed with gallstone ileus. Over a longer period of time they had suffered intermittently from abdominal pain related to a migrating and impacting stone. This disease is mostly diagnosed correctly during exploratory laparotomy for persistent intestinal obstruction. CT scanning, however, is a new and helpful way to early diagnosis. Both women had successful surgery. Gallstone ileus is a disease of the elderly; its early diagnosis is important. CT can be very helpful in this respect.
