Summary
This study demonstrates the feasibility of videoendoscopic thyroid lobectomy in a canine model, showcasing minimal blood loss and no complications. These findings suggest potential applications for minimally invasive surgery in human thyroid procedures.
Area of Science:
- Surgical Innovation
- Veterinary Surgery
- Endoscopic Techniques
Background:
- Minimally invasive surgery (MIS) has expanded beyond traditional cavities.
- New applications and disease processes are being explored for MIS.
- Thyroidectomy is a common surgical procedure with potential for MIS.
Purpose of the Study:
- To evaluate the feasibility of videoendoscopic thyroidectomy.
- To assess the safety and efficacy of this technique in a canine model.
- To explore potential human applications of this novel surgical approach.
Main Methods:
- Adult mongrel dogs were used as the experimental model.
- A videoendoscopic approach was utilized involving a midline neck incision and cervical ports.
- Dissection employed pediatric endoscopic instruments, with hemostasis achieved via clips and ultrasonic coagulation.
Main Results:
- Mean operative time for thyroid lobectomy was 69 minutes.
- Endoscopic identification of laryngeal nerves and parathyroid glands was successful in all cases.
- Minimal blood loss and no intraoperative or postoperative complications were observed.
Conclusions:
- Videoendoscopic thyroid lobectomy is feasible in an animal model.
- The technique provides adequate visualization of critical anatomy.
- This approach may be applicable to human thyroidectomy and other MIS procedures.
