2023 World Conference on Lung Cancer (Posters)-EP01.01. Risk Factors of Intraoperative Air Leakage in Anatomical Pulmonary Resection

Pdf Summary

This study investigated the incidence and risk factors of intraoperative air leakage (IAL) in anatomical pulmonary resection. The study analyzed 194 patients who underwent anatomical pulmonary resection in a hospital from January 2020 to December 2020. The incidence rates of postoperative air leakage (PAL) and postoperative prolonged air leakage (PPAL) were also examined. Various factors, such as age, gender, history of cigarette smoking, lung status, number of automated staplers used, procedures of operation, and amount of blood loss were analyzed to determine their association with IAL.<br /><br />The results showed that IAL was observed in about half of the patients, and there were significant differences in factors such as Brinkman index, operative time, blood loss during operation, and drainage days between the group with IAL and the group without IAL. However, intraoperative factors such as procedures and approach method did not pose a risk of IAL. Interestingly, the number of staplers used for pulmonary resection was significantly higher in the group with IAL, suggesting that damage to the lung parenchyma caused by stapler use may be a risk factor for IAL.<br /><br />The study also examined the incidence rates of PAL and PPAL. PAL was defined as air leakage after postoperative day 1, while PPAL was defined as prolonged air leakage after postoperative day 1 that required additional pleurodesis. The results showed that PAL occurred in 12.9% of patients, and PPAL occurred in 9.2% of patients.<br /><br />In conclusion, this study provides insights into the incidence and risk factors of IAL in anatomical pulmonary resection. The findings suggest that the number of staplers used for pulmonary resection may be a potential risk factor for IAL. Further research is needed to better understand and prevent IAL and its associated complications.
