[Diagnosing intramucosal cancers of the esophagus]

We have come to the following conclusions based on 11 cases of resected mucosal cancers of the esophagus. X-ray findings of esophageal mucosal cancer can be characterized by; concerning marginal changes, limited extension with irregularities. concerning mucosal changes, slightly elevated plateau and shallow erosions. Endoscopic findings can be characterized by reddening, discoloration, shallow depression, coarse mucosal appearance, and plateau showing whitish hue. Lugol dye-scattering turned out to be extremely effective in defining location, size, shape, and spread of cancerous invasion. 8 out of 11 cases were intraepithelial cancers, mostly showing superficial flat type. Mucosal cancers of the esophagus can be detected very effectively, males over 50 being of a high risk and panendoscope being employed.
