Patient-Specific 3D Model-Assisted Preoperative Consultation for Thoracoscopic Lung Resection
Sponsor: Tongji Hospital
Summary
This study is a single-center, cluster randomized controlled trial evaluating whether lung three-dimensional model-assisted preoperative consultation can improve shared decision-making in adult patients undergoing thoracoscopic anatomical lung resection. Six attending thoracic surgeons will be randomized to provide either three-dimensional model-assisted consultation or usual preoperative consultation. Patients in the intervention group will receive consultation supported by a generic lung three-dimensional model and patient-specific three-dimensional reconstruction data generated from routine preoperative imaging. Patients in the control group will receive usual preoperative consultation according to current clinical practice. The primary outcome is patient-perceived shared decision-making measured immediately after consultation using the 9-item Shared Decision-Making Questionnaire. Secondary outcomes include anxiety, disease- and surgery-related knowledge, communication satisfaction, health-related quality of life, decision regret, consultation duration, and postoperative outcomes within 30 days.

Interventions
Lung three-dimensional model and reconstruction-assisted preoperative consultation
In the intervention arm, surgeons will use a generic modular lung three-dimensional model and patient-specific three-dimensional reconstruction data to support preoperative consultation. The reconstruction will be generated from clinically indicated routine imaging examinations and will be displayed dynamically on a physician workstation. The surgeon will use these tools to explain the lesion location, involved lobe or segment, planned resection extent, bronchovascular anatomy, lymph node assessment, potential risks, alternative options, and expected recovery. No additional imaging examination will be performed solely for the study.
Usual preoperative consultation
Patients in the control arm will receive usual preoperative consultation according to current clinical practice. Usual consultation may include oral explanation, review of routine computed tomography images, surgical diagrams, printed materials, and discussion of diagnosis, treatment options, risks, and expected recovery. The lung three-dimensional model and dynamic three-dimensional reconstruction display will not be used.
