Sclerosing cholangitis: a rare etiology for acute pancreatitis.

Primary sclerosing cholangitis as the cause of acute pancreatitis is a rare phenomenon with only one previous case having been found by ourselves in the English literature. Over a period of 2 yr, two patients with acute pancreatitis secondary to primary sclerosing cholangitis were seen in this unit. The first patient is currently being treated with ursodeoxycholic acid and repeat endoscopic sphincterotomies, whereas the second required liver transplantation.
