[Pancreatitis and papillary stenosis: endoscopic retrograde pancreatography (ERP) vs. exocrine functional tests (author's transl)].

Functional tests and ERP were performed in patients with chronic and acute pancreatitis and papillary stenosis; both diseases differ considerably as can be shown by both, pancreatography and degree of functional impairment. The different classification types of pancreatitis are based upon the Marseille Symposium. The ERP is the only x-ray procedure which allows the diagnosis of intrapapillar pancreatic duct stenosis. The ERP significantly improves diagnosis of the early stages of papillary stenosis of the pancreas. Neither secretin-pancreozymin test nor ERP are indicated in cases of primary chronic calcifying pancreatitis; in chronic relapsing calcifying pancreatitis they should be used for preoperative diagnostic purposes.
