Examination of hypopharyngeal and esophageal foreign body for the past 20 years

Abstract

　We examined the types of foreign bodies and extraction methods for 100 cases of hypopharyngeal and esophagus foreign bodies removed under general anesthesia in our department over the past 20 years. Regarding the type of foreign body, fish bones were the most common at 66 cases, dentures at 9 cases, PTP preparations at 8 cases, and food lumps at 7 cases. Examination by age group showed a large number of cases under 10 years old and in their 60s with bimodality. There were many foreign bodies of coins and toys in children, while the proportion of fish bones and PTP denture foreign bodies was high after the 20s. In a comparative study of cases every 10 years, there was an increase in the number of cases in each age group in the last 10 years, and the number of cases aged 65 years and older was significantly increased, which is considered to be associated with the aging society. With regard to PTP foreign bodies, there were cases of accidental ingestion at medical facilities, which is considered to be a subject requiring further study.
