title: Pathogenesis and outcomes of traumatic injuries of the esophagus.
abstract: Traumatic injury of the esophagus is extremely uncommon. The aims of this study were to use the Pennsylvania Trauma Outcome Study (PTOS) database to identify clinical factors predictive of esophageal trauma, and to report the morbidity and mortality of this injury. A cross-sectional review of patients presenting to 20 Level I trauma centers in Pennsylvania from 2004 to 2010 was performed. We compared clinical and demographic variables between patients with and without esophageal trauma both prior to and after arrival in the emergency room (ER). Primary mechanism of injury and clinical outcomes were analyzed. There were 231 694 patients and 327 (0.14%) had esophageal trauma. Patients with esophageal trauma were considerably younger than those without this injury. The risk of esophageal trauma was markedly increased in males (odds ratio [OR] = 2.62 [CI 1.98-3.47]). The risk was also increased in African Americans (OR = 4.61 [CI 3.65-5.82]). Most cases were from penetrating gunshot and stab wounds. Only 34 (10.4%) of esophageal trauma patients underwent an upper endoscopy; diagnosis was usually made by CT, surgery, or autopsy. Esophageal trauma patients were more likely to require surgery (35.8% vs. 12.5%; P < 0.001). Patients with esophageal trauma had a substantially higher mortality than those without the injury (20.5% vs. 1.4%; P < 0.005). In logistic regression modeling, traumatic injury of the esophagus (OR = 3.43 [2.50-4.71]) and male gender (OR = 1.52 [1.46-1.59]) were independently associated with mortality. For those patients with esophageal trauma, there was an association between trauma severity and mortality (OR = 1.10 [1.07-1.12]) but not for undergoing surgery within the first 24 hours of hospitalization (OR = 0.84; 0.39-1.83). Our study on traumatic injury of the esophagus is in concordance with previous studies demonstrating that this injury is rare but carries considerable morbidity (∼46%) and mortality (∼20%). The injury has a higher morbidity and mortality when the thoracic esophagus is involved compared to the cervical esophagus alone. The injury most commonly occurs in younger, Black males suffering gunshot wounds. Efforts to control gun violence in Pennsylvania are of paramount importance.
