[The contribution of gallbladders' infusion tomography in the diagnosis of acute cholecystitis (author's transl)].

The detection of opacification of the wall of the gallbladder after the intravenous injection of hydrosoluble iodinated contrast medium (gallbladder parietography) was sought in 82 patients suspected of suffering from acute cholecystitis. In 35 cases, the examination was negative and operation or the clinical course made it possible to eliminate the diagnosis of acute cholecystitis. In 47 cases, it was positive. The diagnosis was confirmed in 39 cases out of 40 patients undergoing surgery. The appearance of the opacification makes it possible to distinguish two types of positive gallbladder parietography: -- with a thin wall and gallbladder of normal size, corresponding to moderate inflammatory lesions; -- with a thickened wall associated with a large gallbladder corresponding to major inflammatory lesions. The examination is simple, reliable, may be carried out as an emergency and combined with intravenous urography. The diagnosis of acute cholecystitis may be made in difficult causes, and appropriate therapeutic steps taken.
