Application of computer-aided design modified 3D printing model in video-assisted thoracoscopic sublobular resection for early lung cancer:A retrospective cohort study
Objective To compare the effect of three-dimensional visual(3DV)model,three-dimensional printing(3DP)model and computer-aided design(CAD)modified 3DP model in video-assisted thoracoscopic surgery(VATS)sublobular resection.Methods The clinical data of patients who underwent VATS sublobular resection in the Affiliated Hospital of Hebei University from November 2021 to August 2022 were retrospectively analyzed.The patients were divided into 3 groups including a 3DV group,a 3DP group and a CAD-3DP group according to the tools used.The perioperative indexes and subjective evaluation of operators,patients and their families were compared.Results A total of 22 patients were included.There were 5 males and 17 females aged 32-77(56.95±12.50)years.There were 9 patients in the 3DV group,6 patients in the 3DP group,and 7 patients in the CAD-3DP group.There was no statistical difference in the operation time,intraoperative blood loss,drainage volume,hospital stay time or postoperative complications among the groups(P＞0.05).Based on the subjective evaluations of 4 surgeons,the CAD-3DP group was better than the 3DV group in the preoperative planning efficiency(P=0.025),intuitiveness(P=0.045)and doctor-patient communication difficulty(P=0.034);the CAD-3DP group was also better than the 3DP group in the overall satisfaction(P=0.023),preoperative planning difficulty(P=0.046)and efficiency(P=0.014).Based on the subjective evaluations of patients and their families,the CAD-3DP group was better than the 3DP group in helping understand the vessel around the tumor(P=0.016),surgical procedure(P=0.020),procedure selection(P=0.029),and overall satisfaction(P=0.048);the CAD-3DP group was better than the 3DV group in helping understand the tumor size(P=0.038).Conclusion CAD-modified 3DP model has certain advantages in pre-planning,intraoperative navigation and doctor-patient communication in the VATS sublobectomy.
