食道のレ線診断

X-RAY DIAGNOSIS OF THE ESOPHAGUS

Ⅰ．まえおき

　最近，食道の早期癌が相次いで報告^1)～5)されているが，これらの大部分のものは，既に食道鏡検査で診断がつき，X線検査のみでは診断が困難であったという例であって，X線検査はその実をあげることが出来なかった．胃の早期癌におけるX線診断の如き役割を期待するならば，食道のX線診断については更に研究を必要としよう．

　ここで食道のX線検査における基本的な技術や診断方法を述べ症例を示す事が何らかの参考になれば幸いである．

1. The routine radiological techniques for esophageal diseases are briefly described.

2. Some typical cases of benign esophageal diseases, such as functional disturbances, diverticulum, achalasia, stenosis, hiatus hernia, fistula, varices and benign ulcer of the esophagus, are presented with some explanation for reading films.

3. Typical X-ray findings of 1) benign tumors 2) carcinoma and 3) sarcoma are demonstrated with some additional explanation.

4, A proposed radiological classfication for esophageal carcinoma is presented and the usefulness of it for the indication of some treatment methods is explained.

5. One case of so-called early esophageal carcinoma experienced in our clinic is demonstrated. The possibility and the prospect for early diagnosis of the esophageal carcinoma are discussed finally, with special reference to some recently reported early cases in Japan.
