[Endoscopical and radiological studies after papillotomy (author's transl)].

The paper deals with a controlled study concerning 36 patients who underwent surgical papillotomy. Cholangiographic examinations were performed by infusion and endoscopic retrograde instillation, in ten patients additional percutaneaus "blind" biopsy of the liver. Some new remarkable details could be evaluated at the papilla Vateri itself as definite anatomic alteration after papillotomy. Planimetric studies could be added on special details because of the good x-ray-contrasts by endoscopic filling of the biliary tract. With some special reserves the results after surgical papillotomy in 30 controlled persons can be classified as good.
