Purpose : Prolonged air leak (PAL) is a major complication of pulmonary resection. Here, we aimed to analyze the factors that influence PAL in early lung cancer patients who underwent anatomical segmentectomy.
Methods : A total of 42 patients who underwent anatomical segmentectomy for early lung cancer between January 2014 and July 2017 were included for analysis. Several baseline and surgical variables were evaluated. In particular, emphysema index (EI, %) and lobe specific emphysema index (LEI, %), via the use of three-dimensional volumetric CT scans, were included in this analysis.
Results : PAL was observed in 14 patients (25%). There was a statistically significant difference of DLCO (97.3±18.3 vs 111.7±15.9, p=0.014), EI (4.61±4.6 vs 1.17±1.76, p=0.022), and LEI (5.81±5.78 vs 0.76±1.17, p=0.009) between patients with and without PAL. According to the logistic regression analysis, both EI and LEI were found to be significantly associated with PAL (p=0.028 and p<0.001, respectively).
Conclusion : We found that EI and LEI significantly influence the development of PAL after pulmonary resection. Among them, however, LEI appears to be particularly important factor for the prediction of PAL after anatomical segmentectomy.
