Imaging findings in patients with gallstone ileus:
- an ectopic gallstone causing
- partial or complete small bowel obstruction, and
- pneumobilia and/or gallbladder lumen gas
History of the Rigler triad
1941 – Leo George Rigler (1896-1979) described two cases, observed at autopsy, in which the manner of development of a choledochoduodenal and a cholecystoduodenal fistula could be demonstrated.
The specific signs which permit a roentgenologic diagnosis of this condition are evidences of dynamic ileus, presence of gas or contrast medium in the biliary tract and direct or indirect visualization of the calculus.
In 13 of 14 cases of gallstone obstruction in which roentgen examination was made, the exact diagnosis could have been made from the roentgenograms aloneRigler, JAMA 1941
