Summary
Brief summary (as posted)
This study aims to investigate the relationship between the duration of smoking cessation before surgery and postoperative complications in lung cancer patients undergoing surgery. Lung cancer surgery patients who have recently quit smoking or are long-term nonsmokers will be evaluated to determine if the timing of smoking cessation impacts the risk of complications after surgery. By analyzing these factors, the study seeks to provide guidance on optimal smoking cessation timing to reduce postoperative risks.

- Incidence of Postoperative Complications Among Patients Following Lung Cancer Surgery Based on Duration of Smoking Cessation
- timeFrame
- From the day of surgery to 30 days postoperatively
- description
- Postoperative complications will be assessed in patients who have undergone lung cancer surgery. Complications include both pulmonary (e.g., pneumonia, atelectasis, prolonged air leak) and non-pulmonary events (e.g., atrial fibrillation, wound infection) occurring within 30 days after surgery. The duration of smoking cessation prior to surgery will be recorded for each patient, and complications will be documented according to standard clinical criteria. This measure aims to determine if the length of smoking cessation impacts the likelihood and type of postoperative complications.
