Abstract: Objectives:To analyze the features and risk factors of Postoperative Pulmonary Complications of Esophageal Carcinoma.Methods:A total of 295patients who received esophagectomy between March 2014 and May 2015 were included in the study. The patients were assigned into PPC（postoperative pulmonary complications）group and normal group, and postoperative factors were collected and analyzed between two groups, and the multivariate analysis (Logistic regression) were use to identify the risk factors of PPC. Conclusions:①No cases of death occurred in the two groups. The over incidence of PPC was 12.9%(38/295).②Univariate analysis revealed that there were significant differences in age,weight,smoking, preoperative pulmonary function, volume overload(all P<0.05). ③Three variables were found to be significantly related to the development of PPC by multivariate analysis: age(OR=8.71,P<0.05), smoking(OR=12.21 P<0.01), weight(OR=14.43，P<0.01). Results:PPC is a serious complication after esophagectomy. This study shows that age>70 years, smoking and emaciation are risk factors most likely associated with PPC development.
