Pdf Summary

In this study presented at the World Conference on Lung Cancer, the researchers analyzed three-dimensional computed tomography (3D-CT) data to examine the volume changes in the lung before and after segmentectomy for non-small-cell lung cancer. They also aimed to determine which segment is more likely to benefit from segmentectomy.<br /><br />The study included 58 cases of segmentectomy performed between June 2015 and December 2020. The average rate of postoperative lung volume change was found to be 103.3%. The researchers divided the patients into two groups: the compensated group (35 patients) and the uncompensated group (23 patients). They found that the compensated group had a postoperative total lung volume of 100%, while the uncompensated group did not.<br /><br />They also analyzed the characteristics of the patients in relation to lung volume change. They found that there were no significant differences in lung volume change based on age, sex, smoking status, or lung condition. However, they did find that the compensated group was more likely to have undergone thoracoscopic surgery and division of the intersegmental plane by electrocautery.<br /><br />Furthermore, the researchers analyzed the volume changes in specific segments. They found that there was no significant decrease in volume in any of the residual segments compared to the preoperative volume. They also found that postoperative compensatory volume change occurs not only in the ipsilateral lung but also in the contralateral lung.<br /><br />In conclusion, this study suggests that postoperative compensatory volume change occurs in both the ipsilateral and contralateral lung after segmentectomy for non-small-cell lung cancer. They also found that segmentectomy of the right lower lobe showed more compensatory volume growth than segmentectomy of the left lower lobe. These findings can contribute to preoperative planning and improve outcomes for patients undergoing segmentectomy.
