生餅，食道異物のⅠ摘出例

　食道異物としては貨幣，魚骨，玩具，碁石，義歯，梅干の種，其の他種々の報告があり，其の種類は枚挙に遑がない．

　然し戦前の一銭銅貨を幼時が玩具としてもて遊んだ時代には食道異物が圧倒的に多かつた．其の後一銭がアルミ貨幣となつてからは之をもて遊ぶ年令の幼児即ち2〜3歳の幼児の食道では異物とならず，従つて一銭アルミ貨幣の食道異物は急激に減少し，稀に乳児に於て見るのみとなつた．

NAGAI reports a case of esophageal foreign body which was caused by lodging of a piece of "pounded rice cake (mochi)" in a elderly wo-man aged 69. Finding the mass of obstruction at the first esophageal constriction through esophag-oscopy it was removed en toto without attempting the removal by piecemeal. The author stresses the point that, in removal of such resilient foreign bodies as that of "mochi", the use of esophago-scope should not be limited to a particular type of instrument or method but, rather, a combinati-on of them so as to be adapted to the needs of the situation.
