APPRECIATION OF ENDOSCOPY IN DIAGNOSIS OF CANCER OF DUODENAL PAPILLA

Abstract

Recently many cases of cancer of pancreato-biliary tree have been found according to progress of new techniques, for example, ERCP, or PTC and so on. Especially cancer of duodenal papailla seems to have the best resectability and the best prognosis, though there is a problem of finding the disease in early stage. In 21 cases of cancer of duodenal papilla in our clinic, analysis was made on the findings of hypotonic duodenography, cholangiography, and duodenal endoscopy and these cases were classified into three type; swelling type, nodular type, and infiltrating type by endoscopic findings. Retrospective comparative studies were made on the accuracy of diagnosis by these three examinations and also on the probability to diagnose the infiltrating degree of cancer before the operation by judging from some characteristic findings. Endoscopy gave the most accurate diagnosis of this disease and endoscopic classification tend to relate to infiltrating degree of cancer of duodenal papilla.
