Crohn's disease and pancreatitis.

Abstract

Pancreatitis has rarely been reported as a complication of Crohn's disease. We report our experience with two cases of pancreatitis associated with Crohn's disease. In one, the pancreatitis occurred secondary to duodenal Crohn's disease involving the ampulla of Vater. Endoscopic retrograde pancreatography demonstrated involvement of the ampulla, with marked dilation and delayed drainage of the pancreatic duct, suggesting mechanical obstruction. In the second patient, Crohn's disease was localized to the ileum and colon. We conclude that duodenal Crohn's can cause pancreatitis, and this may, in some cases, be on an obstructive basis. In addition, non-duodenal Crohn's disease can be associated with pancreatitis as well. In a patient with a history of Crohn's disease presenting with an atypical exacerbation, pancreatitis should be considered.
