Esophageal perforation following external blunt trauma

Esophageal perforation from external blunt trauma is an exceedingly rare injury. Since 1900, including our five cases, we found 96 reported cases. The most common cause was violent vehicular trauma. The cervical and upper thoracic esophagus was the site of perforation in 82%. In 78% of the cases, there were findings consistent with esophageal injury, but there was a delay in diagnosis in two thirds of these. The diagnostic difficulty was due to lack of a specific symptom complex for esophageal perforation. Often esophageal perforation was not suspected and the symptoms were attributed to the more common injuries, or the diagnostic workup was incomplete. There were 24 (38%) infectious complications directly related to the esophageal perforation. In 21 of these, there was a delay in diagnosis. There were five (9.4%) deaths due to sepsis from the esophageal perforation.
