A retrospective review was performed of patients diagnosed with an esophageal perforation admitted to the London Health Sciences Centre from 1981 to 2007. Univariate and multivariate logistic regression was used to determine which factors had a statistically significant effect on mortality.
There were 119 patients; 15 with cervical, 95 with thoracic, and 9 with abdominal perforations. Fifty-one percent of all the perforations were iatrogenic and 33% were spontaneous. Multivariate logistic regression analysis revealed that patients with preoperative respiratory failure requiring mechanical ventilation had a mortality odds ratio of 32.4 (95% confidence interval [CI] 3.1 to 272.0), followed by malignant perforations with 20.2 (95% CI 5.4 to 115.6), a Charlson comorbidity index of 7.1 or greater with 19.6 (95% CI 4.8 to 84.9), the presence of a pulmonary comorbidity with 13.9 (95% CI 2.9 to 97.4), and sepsis with 3.1 (95% CI 1.0 to 10.1). A wait time of greater than 24 hours was not associated with an increased risk of mortality (p = 0.52).
