Abstract：Objective To evaluate the application effect of chest plain scan and enhanced CT-assisted 3D reconstruc-tion in early-stage non-small cell lung cancer(NSCLC)anatomical segmentectomy.Methods One hundred and twenty early-stage NSCLC patients who underwent thoracoscopic anatomical segmentectomy at the Aerospace General Hospital from March 2021 to March 2023 were enrolled.They were divided into the control group(n=47),plain scan reconstruction group(n=23),and enhanced reconstruction group(n=50).The operation time,intraoperative bleeding,drainage tube retention time,postoperative drainage volume,postoperative hospital stay,number of lymph nodes dissected,margin width,and incidence of adverse reactions were compared among the three groups.Results The operation time,intraoperative bleeding,drainage tube retention time,postoperative drainage volume,postoperative hospital stay,number of lymph nodes dissected,the proportion of resection margin width≥20mm,and the incidence of adverse reactions in the plain scan and enhanced reconstruction groups were significantly better than those in the control group(P<0.01).Compared with the enhanced reconstruction group,the plain scan reconstruction group had a longer operation time(P<0.01).Conclusion Both chest plain scan and enhanced CT 3D reconstruction techniques can assist in anatomical segmentectomy,accurately locate lesions,reduce surgical difficulty,and decrease operation time,intraoperative bleeding,and adverse reactions,thereby improving surgical safety.At the same time,these techniques can shorten drainage tube retention time,postoperative drainage volume,and hospitalization time,facilitating a quicker recovery for patients.
