1ヶ月間嵌在せし食道異物症例

緒言

　小兒の食道異物は往々嚥下の病歴不明であり，又事の眞相を語り得ないために，狹窄症状の軽度のものは他の疾患と間違えられて種々治療を受けるもよくならず，偶々レントゲン写眞を撮影し初めて異物なること判明し事なきを得ることがある．余は最近かかる例でレントゲン写眞によるも尚異物像発見されず，直達檢査によつて初めて異物なる事が判明した例に遭遇した．

Kano reports that esophaguscopy was the means by which diagnosis of foreign body of esophagus, that remained in situ for the period of one month, was made in a made infant 1 year and 4 months of age. The chief complaint of the patient as given by its parent was vomiting. Though it was known to the parents that the infant was given to the habit of taking whatever it could hold to its mouth, they were unaware that it had swallowed a foreign body. For this reason a few pediatricians consulted were unable to establish a care. Radiogram examination also; revealed no abnormality. The foreign body was discovered, only when the patient was examined under esophaguscopy, and, located at the third esophageal constriction but, immediately thereafter it passed on into the stomach. On the third day the foreign body, a piece of metallic aluminum, Was retrieved in the fece. The author further comments on the cause of diagnostic errors, essential points for recognition of esophageal foreign bodies in children and, points of interest concerning aluminum metal as a foreign body.
