Rigler's triad in gallstone ileus

Introduction: Gallstone ileus is a rare cause (۰.۵ percent) of mechanical small bowel obstruction due to gallstone impaction within the lumen of the small intestine after passing through biliary enteric fistula.Clinical Case: The patient was a ۵۸-year-old woman with prior history of cholelithiasis and recurrent biliary symptoms who had referred with complaints of low appetite, nausea, colicky abdominal pain and difficulty in passing stool and gas. In the Physical examination, she was ill with sign of mild dehydration, abdominal distension and increased bowel sounds without guarding and tenderness.The patient was evaluated for intestinal obstruction. According to the abdominal plain radiography findings (signs of partial obstruction and change in previous location of the stone), gallstone ileus was suspected, so the patient underwent an abdominal contrast-enhanced CT. The abdominal contrast-enhanced CT findings that confirmed gallstone ileus include: gallstone in terminal ileum (Figure ۱), small bowel obstruction (Figure ۲) and pneumobilia (Figure ۳).
