[Endoscopic retrograde pancreatography (author's transl)].

Endoscopic retrograde pancreatography is indicated in suspected malformations, chronic inflammation, and tumors of the pancreas. It is contraindicated in acute inflammation and severe obstruction of the main duct. The signs of chronic inflammation are deformities of the ductal system and/or intraductal calculi. Diffuse changes with beading were prominent in 51 patients studied. Malignant tumors cause stenosis, obstruction, tapering, or cavernous deformation of the ductal systm. Complete obstruction of the main duct was seen in the majority of 67 patients studied.
