Abstract Background Three-dimensional (3D) computed tomography (CT) reconstruction technology has gained attention owing to its potential in locating ground glass nodules the lung. The 3D printing additionally allows visualisation of surrounding anatomical structure and variations. However, clinical utility these techniques is unknown. This study aimed establish a lung tumour an model using chest CT evaluate uniportal video-assisted thoracoscopic segmentectomy. Methods Eighty-nine patients with who underwent segmentectomy were classified into following groups: group A, models for pre-positioning simulated surgery that performed printing, B, scans image enhancement reconstruction. differences approach transfer rate, surgical method conversion operative time, intraoperative blood loss, postoperative complication rate compared between two groups. Results Between groups A there significant (0% vs.10.5%, p = 0.030), time (2.07 ± 0.24 h vs. 2.55 0.41 h, < 0.001), loss volume (43.25 13.63 mL 96.68 32.82 mL, 0.001) lobectomy 10.5%, 0.030). In contrast, was insignificant difference B (3.9% 13.2%, 0.132). Conclusions facilitates more accurate location by surgeons, as it based on two-dimensional image-based findings, therefore, can improve accuracy safety. technique worth applying practice.
