[Tumor diagnostic by ERPC and its correlation to pathology (author's transl)]

In relation to 170 pancreatic and bile duct neoplasms confirmed by histology, the radiological signs were correlated to anatomical findings. The roentgenograms were analysed with regard to diagnostic accuracy, size of tumor and operability. 13 319 autopsies of the same period were screened in order to ascertain false positive and as well false negative findings in ERPC. Pancreatic tumors with a diameter over 3 cm were correctly found by ERPC in 98,4%, tumors below 3 cm in diameter in 75%. The over-all diagnostic accuracy for malignant tumors was 90,0%. There were no pathological findings in ERPC in two cases of pancreatic cancer with diameter below 3 cm. 10,5% of all pancreatic neoplasms were operable. Tumors of extrahepatic bile ducts all were discovered by ERPC but all of them were already inoperable.
