Factors affecting perforation of the esophagus in patients with deep neck infection

Abstract

Abstract Background Deep neck infection (DNI) is a serious disease that can lead to severe morbidity, including esophageal perforation, and mortality. However, no previous study has explored the risk factors associated with esophageal perforation in patients with DNI. This study investigated these factors. Methods Between September 2015 and September 2021, 521 patients with DNI were studied. Relevant clinical variables and deep neck spaces were assessed. Results In a multivariate analysis, involvement of the retropharyngeal space (OR 5.449, 95% CI 1.603–18.51, p = 0.006) and the presence of mediastinitis (OR 218.8, 95% CI 55.98–855.3, p < 0.001) were independent risk factors associated with esophageal perforation in patients with DNI. There were no differences in pathogens between 32 patients with and 489 patients without esophageal perforation (all p > 0.05). Conclusion Involvement of the retropharyngeal space and the presence of mediastinitis were independent risk factors associated with esophageal perforation in patients with DNI. There were no differences in pathogens between the groups with and without esophageal perforation in DNI.
