  • Abstract
  • Look Inside

 Of the 1,105 cases of cancer of the esophagus resected in the Institute of Gastroenterology, Tokyo Women's Medical College up to 1982, superficial cancer cases including 46 (4.1%) of early cancer of the esophagus were 74 (6.7%). Among those cases there were 12 (1% of total esophageal cancers operated upon) which were left unnoticed by x-ray examination in other nstitutions. According to the classification of x-ray diagnosis, most of the cases were of superficial flat-type and minute or very shallow superficial depressed ones. At the author's institution, five cases were not discovered during the initial x-ray examination and which were superficial flat-type cancers accompanied by varices and hiatal hernia of the esophagus, and a small (0.7 cm in diameter) superficial depressed-type cancer accompanied by gastric cancer, etc. Most of the cases which were difficult to be noticed by x-ray screening were of superficial flat-type, namely cancers in situ or with submucosal involvement. However, double contrast study made it possible to find a great part of them.

 The following points must be observed in performing screening by x-ray.

 1. Refrain from having an easygoing attitude such as taking x-ray pictures during the examination of the stomach merely by chance.

 2. Not to neglect the fluoroscopic observation because it is easy to detect slight changes through the flow of barium.

 3. To take double contrast pictures without fail. Especially in the cases of high risk groups it is necessary to introduce air through the nasal tube for better photography.

 4. Reading ability of the observer must be improved. Even when the lesion is indicated, there are cases when the observer misses it.

 5. To conduct close x-ray or endoscopic examinations for questionable findings even if they are small.

 When above-mentioned conditions are kept in mind, x-ray examination will surely be able to play its role sufficiently for screening for cancer of the esophagus.
