Summary

Robotic thyroidectomy offers faster operation times and better lymph node retrieval than endoscopic thyroidectomy. The learning curve for robotic procedures is also significantly shorter, making it a more efficient surgical option.

Area of Science:

Surgical Oncology
Minimally Invasive Surgery
Endocrine Surgery

Background:

Endoscopic thyroidectomy presents significant technical challenges.
Robot-assisted thyroidectomy (RAT) enhances visualization and dexterity.
Comparison of conventional endoscopic and robotic thyroidectomy is crucial for patient outcomes.

Purpose of the Study:

To compare perioperative outcomes of endoscopic versus robotic thyroidectomy.
To evaluate the learning curve for both thyroidectomy techniques.
To assess the efficacy of robotic assistance in thyroid cancer surgery.

Main Methods:

A gasless transaxillary approach was used for both endoscopic and robotic thyroidectomy.
96 patients in the endoscopy group and 163 in the robot group were analyzed.

Perioperative results, complications, and learning curves were compared between the two groups.

Main Results:

Robotic thyroidectomy demonstrated a significantly shorter mean operation time (110.1 min vs. 142.7 min).
Mean central lymph node retrieval was higher in the robot group (4.5 vs. 2.4 nodes).
The learning curve for robotic thyroidectomy (35-40 cases) was shorter than for endoscopic thyroidectomy (55-60 cases).

Conclusions:

Robotic thyroidectomy surpasses endoscopic thyroidectomy in operation time, lymph node yield, and learning curve efficiency.
Complication rates and hospital stay were comparable between the two surgical methods.
Robotic assistance represents an advancement in thyroidectomy for cancer patients.
