Retrospective study of ten infants and young children in whom an unsuspected foreign body was found in the esophagus revealed that all had had wheezing of difficulty swallowing solid food. In four, stridor or wheezing had been ascribed to respiratory infection. All foreign bodies were in the upper esophagus. Their presence can cause prolonged, severe morbidity. They can be identified by radiography of the neck and chest, occasionally supplemented by barium studies.
对10例在食管中发现意外异物的婴幼儿进行的回顾性研究显示，所有患儿均有吞咽固体食物困难伴喘息症状。其中4例的喘鸣或喘息曾被归因于呼吸道感染。所有异物均位于食管上段。它们的存在可导致长期、严重的发病情况。通过颈部和胸部X线检查可识别异物，偶尔需辅以钡剂造影检查。
