Abstract

Purpose: Postoperative pneumonia is one of the major complications after esophageal cancer surgery. The risk factors associated with postoperative pneumonia are poor general health, smoking, decreased pulmonary function, diabetes mellitus, surgical stress, old age, postoperative aspiration, and oral hygiene. In this study, we examined the effect of perioperative oral care on reducing postoperative pneumonia since the evidence to-date is not clear. Methods: A multicenter, retrospective investigation of the relationship between perioperative oral care and incidence of postoperative pneumonia in patients undergoing esophageal cancer surgery was conducted. A total of 775 patients who underwent thoracoscopic esophageal resection at 25 hospitals between 2016 and 2017 were enrolled in the study. Various factors were examined for correlation with development of postoperative pneumonia. Results: Multivariate analysis showed that old age, smoking habit, lower hemoglobin, higher creatinine, postoperative dysphagia, and lack of oral care intervention were independent risk factors for pneumonia. Oral care was more effective in preventing pneumonia in hospitals in which the incidence of postoperative pneumonia was lower than 20%, while it was not effective in hospitals in which the incidence was higher than 20%. Conclusion: Results of the study suggest that it is recommended to carry out perioperative oral care in esophageal cancer surgery.
