Duodenal diverticulum and associated pancreatitis: case report with brief review of literature.

Pancreatitis in the elderly is a problem of increasing occurrence and is associated with severe complications. Periampullary diverticula (PAD) are extraluminal outpouchings of the duodenum rarely associated with pancreatitis. The presence of PAD should be excluded before diagnosing idiopathic pancreatitis, particularly in the elderly. However, when a duodenal diverticulum is found in the absence of any additional pathology, only then should the symptoms be attributed to the diverticulum. We describe a case of duodenal diverticulum presenting with pancreatitis to emphasize the importance of this commonly neglected etiology.
