Abstract Background Postoperative pulmonary complications (PPCs) represent the most frequent complications after esophagectomy. The aim of this study was to identify modifiable risk factors for PPCs and 90-days mortality related to PPCs after esophagectomy in esophageal cancer patients. Methods This is a single center retrospective cohort study of 335 patients suffering from esophageal cancer who underwent esophagectomy between 1996 and 2014 at a university hospital center. Statistical processing was conducted using univariate and multivariate stepwise logistic regression analysis of patient-specific and procedural risk factors for PPCs and mortality. Results The incidence of PPCs was 52% (175/335) and the 90-days mortality rate of patients with PPCs was 8% (26/335) in this study cohort. The univariate and multivariate analysis revealed the following independent risk factors for PPCs and its associated mortality. ASA score ≥ 3 was the only independent patient-specific risk factor for the incidence of PPCs and 90-days mortality of patients with an odds ratio for PPCs being 1.7 (1.1–2.6 95% CI) and an odds ratio of 2.6 (1.1–6.2 95% CI) for 90-days mortality. The multivariate approach depicted two independent procedural risk factors including transfusion of packed red blood cells (PRBCs) odds ratio of 1.9 (1.2–3 95% CI) for PPCs and an odds ratio of 5.0 (2.0–12.6 95% CI) for 90-days mortality; absence of thoracic epidural anesthesia (TEA) revealed the highest odds ratio 2.0 (1.01–3.8 95% CI) for PPCs and an odds ratio of 3.9 (1.6–9.7 95% CI) for 90-days mortality. Conclusion In esophageal cancer patients undergoing esophagectomy via thoracotomy, epidural analgesia and the avoidance of intraoperative blood transfusion are significantly associated with a reduced 90-days mortality related to PPCs.
