ENDOSCOPICAL STUDY ON PRIMARY DUODENAL CANCER

Abstract

In our clinic, 7 cases of primary duodenal cancer except cancer of the duodenal papilla were experienced. We have examined X-ray and endoscopic findings and clinical courses of these cases. These lesions, located in the duodenal bulb, the second and the third portions of the duodenum showed some characteristic findings, in each location in our study. On X-ray examination, cancer of the bulb and the second portion was shown as a polypoid lesion, but cancer of the third portion was shown to be an ulcertive lesion such as Borrmann II type of gastric cancer. On the other hand, endoscopy was performed in all cases, but 2 cases at the third portion were not seen, because of being unable to approach to the lesions. On endoscopic findings, cancer of the bulb and the second portion appeared to be a polypoid lesion like II a or Borrmann I type of gastric cancer. We guess that duodenal cancer might progress and change from polypoid to ulcerative lesion. Finally, we must refer to a miserable prognosis of these cases, because these patients were seen at late stage of cancer after suffering for too long period.
