Summary
Transoral endoscopic thyroidectomy using the da Vinci SP robotic system is feasible. This flexible robotic approach allows for total thyroidectomy with preserved recurrent laryngeal nerves.
Area of Science:
- Minimally Invasive Surgery
- Robotic Surgery
- Endocrine Surgery
Background:
- Transoral endoscopic thyroidectomy utilizes oral vestibule access and gas insufflation for remote access surgery.
- The da Vinci SP is a next-generation flexible single-port robotic system with advantages over rigid systems.
Purpose of the Study:
- To evaluate the feasibility of transoral thyroidectomy using the da Vinci SP flexible robotic system.
Main Methods:
- Cadaveric dissection with gas insufflation was performed.
- A 2 cm vestibular incision was made, creating a working space with a central 1 cm port and two lateral 5 mm ports.
- The da Vinci SP system was deployed through a wound protector, maintaining insufflation at approximately 6 mmHg.
Main Results:
- The da Vinci SP system was successfully deployed with three instrument arms.
- Thyroid gland mobilization and bilateral recurrent laryngeal nerve preservation were achieved.
- The final vestibular incision measured 3 cm, with mental nerves identified more than 1 cm from the incision's lateral extent.
Conclusions:
- Transoral total thyroidectomy with gas insufflation is feasible using the da Vinci SP flexible robotic system.
- Further studies are required to validate the clinical applicability of this technique.
