食道魚骨異物の統計的観察

抄録

A statistical study was made on 104 cases of esophageal foreign bodies treated in our clinic during the past 5 years and 7 months from 1990 to 1995. The results follow:
1) The male-female ratio was 1: 1.3, and 49 cases (47%) were over 50 years of age.
2) The most common foreign body was fish bones (38%), followed by P. T. P. (press through packs of medicine, 20%), coins (19%), dentures (6%) and others.
3) Fish bones were found in 39 cases, in which the male-female ratio was 1: 1.6, and 30 cases (77%) were over 50 years of age.
4) We classified the wounds resulting from fish bones in the esophagus as follows: normal, slight, moderate and severe.
5) The wound scores were significantly related to both the period from the onset to the visit to a clinic and the size of the fish bone.
6) In general, complications from fish bones in the esophagus, such as periesophageal abscess, retropharyngeal abscess and mediastinitis, rarely occur. When these major complications are suspected, a contrast-enhanced CT scan is recommended.
