Summary
Pause ventilation, using transnasal humidified rapid-insufflation ventilatory exchange (THRIVE), facilitates challenging lymph node dissection during uni-portal video-assisted thoracoscopic lobectomy (UVATS). This technique enhances surgical exposure and safety.
Area of Science:
- Thoracic Surgery
- Minimally Invasive Procedures
- Surgical Techniques
Background:
- Uni-portal video-assisted thoracoscopic lobectomy (UVATS) is established, but complete lymphadenectomy, especially for left hemithorax lymph nodes (LHLN), is difficult.
- Limited research exists on using pause ventilation during UVATS for LHLN dissection.
Purpose of the Study:
- To propose and evaluate the application of pause ventilation for facilitating LHLN dissection during UVATS.
- To demonstrate the surgical procedure using an operative video.
Main Methods:
- Implementation of an intermittent apnea technique via transnasal humidified rapid-insufflation ventilatory exchange (THRIVE).
- Application of pause ventilation during UVATS to enable LHLN dissection.
- Detailed description of the surgical procedure.
Main Results:
- Pause ventilation effectively promotes LHLN dissection during UVATS.
- The technique allows for clear exposure of surrounding tissues and organs.
Conclusions:
- Pause ventilation for LHLN dissection in UVATS is a safe and feasible approach.
- This method improves surgical visualization and facilitates complete lymphadenectomy.
