[Radiologic studies in the diagnosis of biliary ileus].

The authors, after a short reference to considerations of general order, report 6 cases of gallstone-ileus. The number of cases, studied with the traditional X-ray procedure (with and without contrast means) are quite various for the occlusion at different levels of the small bowel, and exactly from the duodenal bulb to the Bowin valve, and for the X-ray symptomatology complete and incomplete. At last it must be underlined the high percentage where the stone of the gallbladder was ascertained, and which is to be considered responsible of intestinal occlusion; this ascertainment has been a very precious element to the right diagnosis of the gallstone-ileus.
