[Gallstone ileus--a diagnostic and indications problem--report on 35 patients].

The clinical data of 35 patients with gallstone ileus treated between 1970 and 1984 at the Department of Surgery of the University Hospital of Freiburg were retrospectively analysed with respect to duration of symptoms prior to surgery, preoperative diagnostic, operative procedure and outcome. No reliable test could be found that will lead the clinician to the correct diagnosis in most cases. The classical sign of gallstone ileus--small bowel obstruction combined with pneumobilia in the plain abdominal X-ray--was apparent only in 20%. So, a high index of suspicion, especially in old female patients with small bowel obstruction and prompt surgical intervention will decrease mortality. Enterotomy with removal of the stone without simultaneous cholecystectomy can be recommended as a safe procedure even in very old patients.
