Objective To analyze the effect of three-dimensional (3D) reconstruction technique combined with anatomical segmentectomy (SA) on tumor markers, inflammatory response, blood gas indexes, and lung function in patients with non-small cell lung cancer (NSCLC). Methods From January 2022 to October 2024,74 patients with NSCLC who video-assisted thoracoscopic surgery SA (SA-VATS) in Fuyang People's Hospital were selected as the SA-VATS group, and 31 patients with NSCLC who underwent 3D three-dimensional reconstruction combined with SA-VATS were selected as the 3D group. The operation-related indexes and postoperative complications during hospitalization were statistically analyzed. The levels of serum tumor markers, inflammatory factors, and blood gas indexes before and 7 d after operation, and lung function before and 1 month after operation were compared between SA-VATS group and 3D group. Results The improvement of operation related indexes in 3D group was better than that in SA-VATS group (P<0.05). The levels of serum vascular endothelial growth factor, heat shock protein 90α, carcinoembryonic antigen, and cytokeratin 19 fragment in SA-VATS group and 3D group at 7 d after operation were lower than those before operation, and those in 3D group were lower than those the SA-VATS group (P<0.05). The levels of serum interleukin-8, interleukin-10, and tumor necrosis factor-α in the SA-VATS group and 3D group at 7 d after operation were higher than those before operation, but those in 3D group were lower than those in SA-VATS group (P<0.05). The changes of blood gas indexes in SA-VATS group and 3D group were improved at 7 d after operation, and 3D group was better than SA-VATS group (P<0.05). The pulmonary function indexes of SA-VATS group and 3D group at 1 month after operation were lower than those before operation, but those in 3D group were higher than those in SA-VATS group (P<0.05). During hospitalization after operation, there was no significant difference in the incidence of total complications between 3D group and SA-VATS group (P>0.05), but 3D group was lower than SA-VATS group. Conclusions 3D reconstruction technique combined with SA-VATS in the treatment of patients with NSCLC could effectively shorten operation time, reduce intraoperative blood loss, promote postoperative recovery of patients, reduce the level of serum tumor markers, alleviate inflammatory response, improve blood gas index and lung function, and might help to reduce the occurrence of complications.
