Summary
A new swine model effectively trains surgeons in anatomical thoracoscopic lung segmentectomy. This minimally invasive technique is crucial for improving patient outcomes in lung surgeries.
Area of Science:
- Thoracic Surgery
- Surgical Education
- Minimally Invasive Procedures
Background:
- Demand for thoracoscopic lung segmentectomy is rising, but standardized training methods are lacking.
- A novel swine model was developed to address this training gap for anatomical lung segmentectomy.
Purpose of the Study:
- To establish and evaluate a live swine model for anatomical thoracoscopic lung segmentectomy training.
- To provide a platform for surgical skill development in minimally invasive lung procedures.
Main Methods:
- Utilized 3-month-old pigs (40-45 kg) for anatomical thoracoscopic lung segmentectomy.
- Performed anterior segmentectomy and left caudal lobe segmentectomy under general anesthesia with differential ventilation.
- Included lectures and surgical skill drills for participating surgeons.
Main Results:
- 33 pigs and 51 trainees were involved between 2010 and 2015.
- The complete thoracoscopic approach was used in 25 pigs, with 3 requiring conversion to thoracotomy.
- The no-touch method in supine position achieved sufficient intersegmental delineation in 76% of cases.
Conclusions:
- The developed live swine model is suitable for training surgeons in anatomical thoracoscopic lung segmentectomy.
- This model facilitates the acquisition of skills for minimally invasive lung segmentectomy applicable to human patients.
