[Roentgenologic contribution to the diagnosis of gallstone ileus]

Between 1969 and 1982 8 patients of ours were operated on for gallstone ileus. Signs found in the preoperative x-ray examination indicating this condition are analyzed retrospectively. The frequency and specificity of the x-ray signs found in the abdominal survey radiograph are compared with those reported in the literature. The value of oral contrast media administration in the detection of a cholecystointestinal fistula and localization of the obstruction is discussed.
