Two cases of the early gastric cancer of which initial cytologic examination happened to reveal cancer cells in the duodenal juice collected by drainage (PS test)

Abstract

Atypical cells were found in the duodenal juice as pirated by pancreozyminsecretin stimulation method from two cases of early gastric cancer. And cell morphology of the gastric cancer was found to differ from that of pancreaticobiliary cancers in some respects.
It is emphasized that it is important to distinguish them from each other by identifying their morphologic differences in exfoliated cancer cells, so as to eliminate the risk of gastric cancer cells being misplaced in the duodenal juice.
