External penetrating injuries of the esophagus are more likely to cause
serious morbidity and even mortality than those involving the pharynx.
However, the cervical esophagus is extrathoracic in location, and controversy
exists regarding the diagnosis and surgical management of penetrating injuries
at this level. A retrospective review of 23 such injuries showed that contrast
esophagography had only a 62% success rate in identification of cervical
esophageal violations, compared to 100% for rigid esophagoscopy. Even large
penetrations were successfully treated with limited debridement, primary
repair when possible, muscle interposition flaps to separate common injuries
of the tracheal wall, and, most important, external drainage of the adjacent
neck spaces. Esophageal stricture occurred only when complex esophageal
diversion procedures were performed, either as an unnecessary primary operation,
or as a lifesaving secondary operation necessitated by infectious complications
caused by delayed diagnosis and treatment of the esophageal violation.
Penetrating injuries of the cervical esophagus can therefore be managed
more as a pharyngeal injury if diagnosis and appropriate surgical treatment
occur in a timely fashion.
