Recurrent pancreatitis caused by a calcified ascaris in the duct of Wirsung.

A case report of recurrent pancreatitis in a 20-yr-old woman due to an impacted calcified Ascaris remnant within the duct of Wirsung is presented. Endoscopic retrograde cholangiography identified a filling defect in the proximal main pancreatic duct. Transampullary endoscopic retrieval failed to extract the calculus and operative intervention was required to remove the calcified worm remnant.
