四国中央病院10年間の食道異物症例の統計的観察

A STATISTICAL REVIEW OF ESOPHAGEAL FOREIGN BODIES

　I．はじめに

　耳鼻科領域における異物は，気道および食道異物が主なもので，いずれも若干増加する傾向にあるという。気道，食道の異物の死亡率は漸次減少の傾向はあるが，わが国では，小野らによれば，食道異物は4.8％，気道異物1.0％で，食道異物は気道異物よりも死亡率が高く危険なものである^1）。公立学校共済四国中央病院における昭和35年5月より昭和44月6年までの最近10年間における食道異物症例について，統計的観察をこころみたので報告する。

　A statistical review of esophageal foreign body cases examined at the Shikoku Central Hospital for the recent 10 years, May, 1959 to June, 1969, is made.

　There were a total of 22 cases, but 16 of these were children below the age of 5. The male female ratio was 1.7:1, more prevalent in the males.

　Seventy two and eight tenths percent of cases were due to hard-coins; mostly caught at the first esophageal constriction.

　In children less than 10 years of age the esophagoscopy is performed under general anesthesia. The foreign bodies that may slip into the intestines are watched with x-ray follow-ups for 3 or 4 days, until anal expulsion is confirmed.
