Blunt Pharyngoesophageal Injuries: Current Management Strategies

Abstract

Background:: Blunt pharyngoesophageal injuries pose a management challenge to the trauma surgeon. The purpose of this study was to explore whether these injuries can be managed expectantly without neck exploration.

Methods:: The National Trauma Databank datasets 2007-2011 were reviewed for blunt trauma patients who sustained a pharyngeal injury, including an injury to the cervical esophagus. Patients who survived over 24 h and were not transferred from other institutions were divided into two groups based on whether a neck exploration was performed. Outcomes included mortality and hospital stay.

Results:: A total of 545 (0.02%) patients were identified. The median age was 18 years and 69% were male. Facial fractures were found in 16%, while 13% had an associated traumatic brain injury. Of the 284 patients who survived over 24 h and were not transferred from another institution, 65 (23%) underwent a neck exploration. The injury burden was significantly higher in this group as indicated by the higher median Injury Severity Score (17 vs 10, p < 0.01) and need for intensive care unit admission (75% vs 31%, p < 0.01). The overall mortality was 2%: 3.1% for neck explorations versus 1.6% for conservative management (adjusted p = 0.54). Neck exploration patients were more likely to remain longer in the hospital (median 13 vs 10 days, adjusted p = 0.03).

Conclusion:: Pharyngoesophageal injuries are rare following blunt trauma. Only a quarter require a neck exploration and this decision appears to be dictated by the injury burden. Selective non-operative management based on clinical status seems to be feasible and is not associated with increased mortality.
