Non-iatrogenic esophageal trauma: a narrative review

BACKGROUND AND OBJECTIVE: Non-iatrogenic esophageal trauma is a rare entity that has a high morbidity and mortality. The diagnosis can often be quite challenging, however is critical to perform in a timely manner. The workup and management of non-iatrogenic trauma continues to evolve, with new innovative approaches available for both diagnosis and treatment. The aim of this narrative review is to comprehensively describe the incidence, presentation, workup, treatment approaches and outcomes of non-iatrogenic esophageal trauma. METHODS: A thorough literature review was performed using full length articles available in English via PubMed between January 1, 1960 to September 30, 2021, focusing on the epidemiology, workup and treatment of non-iatrogenic esophageal trauma, including current surgical techniques. KEY CONTENT AND FINDINGS: Injuries to the cervical esophagus are more common than injuries to the thoracic esophagus, occurring more in young males, with significant racial disparity. Penetrating trauma via gunshot wounds are the most common forms of injury, followed by stab wounds and blunt trauma. Workup is multimodal and involves a combination of plain radiographs, computed tomography (CT) scans, endoscopy and fluoroscopy depending of the stability of the patient and associated injuries. CONCLUSIONS: Workup and management of non-iatrogenic esophageal trauma depends on the location and extent of esophageal injury, and can include observation, debridement and drainage, esophageal diversion, endoscopic approaches or esophagectomy, with indications, techniques and outcomes described in further detail in this review.
