Enterolith ileus: a rare complication of duodenal diverticula.

Small bowel obstruction secondary to an enterolith formed within a duodenal diverticulum is a rare complication. Twenty-nine cases of enterolith ileus have been reported in the literature. This is a case report of the 30th, with review of the literature. Enterolith ileus closely resembles gallstone ileus in its clinical presentation. Diagnosis is established by documenting normalcy of gallbladder and the presence of small bowel diverticula.
