Description

Sixty-four cases of foreign bodies in the esophagus treated at the otorhinolaryngological clinic of Osaka Medical College, during the period from 1972 to 1977 were studied statistically.<br>The results were as follows:<br>1) The incidence of foreign bodies in the esophagus was highest in 1974 (19 cases) and decreased substantially thereafter.<br>2) Almost half of the patients were infants, with a high incidence in those aged 1 (12 cases) and 2 (14 cases).<br>3) Of the 64 cases, 43 were males and 21 were females, that is, the incidence was about twice as high in the males. The sex difference in incidence was observed more dominantly in children under 10 years old.<br>4) Fifty-eight percent of the foreign bodies were coins; 24 out of 37 were 10-Yen coins.<br>5) About 60% of the foreign bodies were located atthe first constriction of the esophagus.<br>6) Dental prosthesis was the most difficult of all types of foreign bodies to remove. Since the use of dental prosthesis has become more common even in the younger generation, the number of cases with detal prosthesis is increasing. The authors emphasized that improvements are necessary in the method of removing dental prosthesis foreign bodies.
