Gallstone ileus: Computed tomography findings

Abstract

Gallstone ileus (GI) is an unusual but serious complication of biliary stone and it is caused by a fistula betweenthe bile ducts and stomach, duodenum or colon. Gallstone that reaches the intestinal tract can be cause ileus.Early diagnosis with imaging modalities (such as computed tomography) and treatment of ileus are of greatimportance for survival. In addition, accurate diagnosis of underlying cause of the ileus is also important becauseit will guide the surgeon.We present a 73-year old patient with gallstone ileus preoperatively diagnosed with computed tomography (CT).CT showed gastric distention, dilated duodenal and jejunal small bowel loops, a calculus in the jejunal segmentof the small bowel and enteral contrast medium reflux into the fistula tract and bile ducts.
