Abstract
Although duodenal diverticula are often found in asymptomatic patients, perforation of a duodenal diverticulum is rare. We experienced a case of perforation of a duodenal diverticulum is rare. We experienced a case of perforation of a duodenal diverticulum caused by incarcerated enterolith.
An 86-year-old woman was admitted to our hospital because of right lower abdominal pain. On the basis of abdominal CT findings we diagnosed the case as perforation of a duodenal diverticulum and performed an emergency operation. During surgery, we found enterolith incarcerated in a diverticulum and its resultant perforation of the diverticulum at the posterior wall of the descending part of the duodenum. Removal of the diverticulum and closure of the defect were performed. The patient was discharged from the hospital on the 33rd postoperative day without serious complications. So far nine other cases of perforation of a duodenal diverticulum caused by enterolith have been reported in Japan, and surgical therapy was employed in them.
