      Background

      Smoking cessation is one of the most important preoperative preparatory acts before thoracic surgery; however, the optimal timing for preoperative smoking cessation has not been clarified. In this study, we examined the effect of short-term smoking cessation before pulmonary resection for preventing postoperative pulmonary complications (PPCs).

      Method

      We enrolled 753patients who underwent curative surgical resection for thoracic malignancies from 3institutions. We instructed patients with a smoking history to quit smoking by at least four weeks prior to surgery in order to reduce the incidence of pulmonary events. We collected information on the preoperative smoking status, duration of smoking cessation before surgery, and occurrence of postoperative pulmonary complications. Study subjects were classified into three groups based on their smoking status. Recent smokers were defined as any who had smoked within two months before surgery, and former smokers were defined as those who had abstained from smoking for more than two months prior to the operation. Never-smokers were defined as those who had never smoked. We examined the relationship between the duration of the preoperative smoke-free period and the development of PPCs.

      Result

      The mean age of the patients was 68 years old, including 426 males and 327 females. Former smoker accounted for 48% (n =361) of the cases, followed by never smokers (n=287, 38%) and recent smokers (n=105, 14%). Surgery was performed for 660 primary lung cancer and 93 metastatic lung tumor. The types of procedures performed included lobectomy (n=542), pneumonectomy (n=11), wedge resection (n=167) and segmentectomy (n=33). PPCS were observed 62 cases (8%) among all patients. The incidence of PPCS among recent, former and never-smokers was 15%, 8% and 6%, respectively (p=0.01). The mean duration of post-operative chest tube drainage among recent, former and never-smokers 3.2, 2.2 and 2.2 days, respectively (p=0.04). The mean post-operative hospital stay among recent, former and never-smokers was 12.1, 10.6 and 10.2 days, respectively (p=0.07). There were no cases of 30-day mortality.

      Conclusion

      Cigarette smoking was associated with PPCS such as respiratory failure, pneumonia, empyema, atelectasis and prolonged air leakage. In addition, cigarette smoking generated a harmful effect for post-operative short-term outcome. Smoking abstinence for at least 2 months prior to surgery was not shown to reduce the incidence of PPCs.
