Intermittent gallstone ileus following endoscopic biliary sphincterotomy. A case report.

A 72-year-old woman presented with periods of colicky abdominal pain following endoscopic sphincterotomy and lithotripsy for choledocholithiasis. A diagnosis of intermittent gallstone ileus was made, while it appeared that a large gallstone, that was not removed from the common bile duct, obstructed the small bowel. The intermittent course was elicited by pendulation of a gallstone between two stenoses, which originated from chronic radiation enteritis.
