Chronic pancreatitis and inflammatory bowel disease: true or coincidental association?

Objective: Several cases of pancreatitis have been described during the course of Crohn's disease (CD) or ulcerative colitis (UC), but many of them were related to either biliary lithiasis or drug intake. We tried to evaluate the clinical and morphological features of so-called idiopathic pancreatitis associated with inflammatory bowel disease and to define their pathological characteristics.

Methods: Chronic idiopathic pancreatitis was diagnosed on the basis of abnormal pancreatograms suggestive of chronic pancreatitis associated with or without impaired exocrine pancreatic function, or pathological examination in patients undergoing pancreatic resection.
