Preoperative Counseling

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.
