Patient-Specific 3D Model-Assisted Preoperative Consultation for Thoracoscopic Lung Resection

3. Juli 2026 aktualisiert von: Zhang Ni, Tongji Hospital

Patient-Specific Three-Dimensional Thoracic Anatomical Model-Assisted Preoperative Consultation to Improve Shared Decision-Making in Patients Undergoing Thoracoscopic Lung Resection: A Single-Center Cluster Randomized Controlled Trial

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.

Beschreibung

Inclusion Criteria:

  1. Adults aged 18 years or older.
  2. Scheduled to undergo elective thoracoscopic anatomical lung resection for suspected or confirmed lung tumors, defined as lobectomy or segmentectomy.
  3. The planned operation and relevant alternatives can be reasonably discussed during preoperative consultation by the attending thoracic surgeon.
  4. Clinically stable and able to participate in preoperative consultation.
  5. Able to read, understand, and complete Chinese questionnaires independently or with neutral assistance from research staff.
  6. Able and willing to provide written informed consent. -

Exclusion Criteria:

  1. Emergency surgery.
  2. Planned wedge resection only, pneumonectomy, extrapleural pneumonectomy, or non-thoracoscopic open surgery at recruitment.
  3. Previous major ipsilateral thoracic surgery that substantially alters thoracic anatomy and may make the generic model misleading.
  4. Known cognitive impairment, severe psychiatric disorder, severe visual impairment, severe hearing impairment, or language barrier that prevents effective participation in consultation or questionnaire completion.
  5. Participation in another interventional study expected to affect preoperative anxiety, patient education, decision-making, or perioperative communication.
  6. Any other condition judged by the investigators to make the patient unsuitable for this study.

Waffen und Interventionen

Teilnehmergruppe / Arm
Intervention / Behandlung
Experimental: Lung 3D model and reconstruction-assisted consultation
Patients will receive usual preoperative consultation supplemented by a generic modular lung three-dimensional model and patient-specific three-dimensional reconstruction data generated from clinically indicated routine imaging examinations.
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.
Aktiver Komparator: Usual preoperative consultation
Patients will receive usual preoperative consultation according to current departmental practice without structured use of the lung three-dimensional model or workstation-based dynamic three-dimensional reconstruction display.
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.
