　食道及氣道異物に關しては昭23年總會で表示し，詳細は食道は最新醫學3卷6號，氣道は日本臨床6卷5號に掲載したが西端主幹の乞に依り耳鼻咽喉科全領域に亙り本題の概要を記し，難題に關しては，例えば食道瘢痕狹窄者に枇杷種子の異物又氣管支異物除去後の肺炎の急變等の豫防及治療に關しては諸賢の御研究を願う次第である．

Yamakawa reports that 2132 cases of foreign body in the realm otolaryngology have been in the period of 17years. By selecting 24 cases that have died from among this numder the author comments upon precautionary measures for pre-vention of such catastrophies, particularly in cases of esophageal or tracheal foreign bodies.

The contributing causes of deaths in esophageal cases are mentioned as, emphysema, empyema pneumothorax, mediastinitis, pneumonia, perfora-tion of the trachea, and asphyxia. The discussion on the prevention of asphyxia during the process of removal of the foreign body from the esoph-agus is enlightening.

Foreign body in the upper air passage, during an attempt at removal, may slip through the aperture of the vocal cords and to be lodged im-mediately bellow them, an accident invariably causing asphyxiation. In such emergencies the fore ign body should be first dislodged by pushing it down towards one of the bronchus and artificial respiration should be resorted to immediately.
