[Endoscopic retrograde catheterization of Vater's ampulla in the diagnosis of bilio-pancreatic diseases].

The technique, indications and contraindications for endoscopic retrograde cholangiopancreatography are discussed. Some of the most demonstrative cholangiographic and pancreatographic pictures are described and the reasons that have led to a marked reduction in complications immediately after the examination are analysed. Therapeutical aids for limiting any slight disturbances connected with the examination are also presented. Finally, some morphological data useful for differentiating between inflammatory and neoplastic lesions in the juxta- and intrapancreatic biliary excretory way and the pancreas itself are considered.
