SALAZAR-OCHOA, Santiago et al. Pneumomediastinum in blunt trauma: Are invasive studies always necessary to rule out aerodigestive injury?. rev. colomb. cir. [online]. 2022, vol.37, n.2, pp.237-244. Epub 30-Abr-2022. ISSN 2011-7582. https://doi.org/10.30944/20117582.1150.
Introduction.
The presence of pneumomediastinum secondary to blunt trauma is a common finding, especially with the use of computed tomography. Although in most cases the presence of pneumomediastinum is secondary to a benign etiology, the possibility of an underlying aerodigestive injuries has led to the recommendation of the routine use of endoscopic studies to rule them out. The purpose of this study was to determine the incidence of pneumomediastinum secondary to blunt trauma and associated injuries and to establish the role of multidetector computed tomography in the diagnosis of aerodigestive injuries.
Methods.
Using multidetector computed tomography, patients with a diagnosis of pneumomediastinum secondary to blunt trauma were identified over a period of 4 years in a Level 1 Trauma Center.
Results.
Forty-one patients diagnosed with pneumomediastinum secondary to blunt trauma, were included in this study. Two airway ruptures were documented: two tracheal injuries and one esophageal injury. Two of them suspected on multidetector computed tomography and confirmed on bronchoscopy and esophagogastroduodenoscopy, respectively, and another was diagnosed in surgery.
Conclusion.
The routine use of endoscopic studies in patients with pneumomediastinum secondary to blunt trauma is not indicated when the clinical and tomographic findings are not suggestive of aerodigestive injury.
