Although rarely recognized, traumatic pharyngeal and cervical esophageal pseudodiverticula are probably not infrequent in newborns who have undergone vigorous oropharyngeal suctioning and endotracheal intubation. This report describes four premature infants with clinically unsuspected retroesophageal false passages incidentally discovered on chest radiographs. Differentiation of pseudodiverticula from spontaneous rupture of the middle or distal esophagus can be achieved by careful inspection of the course of the feeding catheter in frontal and lateral projections and by partial withdrawal of the catheter to permit injection of the retroesophageal false passage with a small volume of water-soluble contrast material.
尽管很少被认识到，但在经历过强力口咽吸引和气管插管的新生儿中，创伤性咽和颈段食管假性憩室可能并不少见。本报告描述了4例早产儿，其食管后假通道在胸部X线片上偶然发现，临床上未被怀疑。通过在正位和侧位投照中仔细观察喂养导管的走行，以及部分撤回导管以便用少量水溶性造影剂注入食管后假通道，可实现假性憩室与食管中、远端自发性破裂的鉴别。
