An observational study in Pain, Postoperative, Thyroid Diseases and Surgery, sponsored by Shanghai 6th People's Hospital. Recruiting at 1 site in China. Per ClinicalTrials.gov, last updated 2026-06-24.
Sponsored by Shanghai 6th People's Hospital · Observational
Postoperative pain is a good indicator to confirm the advantages of the surgical methods in the era of minimally invasive surgery. Lateral neck dissection requires extensive dissection which may leads to postoperative numbness and pain. Robotic thyroid surgery has the advantage of precise and careful dissection and avoid the L-shape incision in the open approach. The study aims to explore the pain intensity and severity of lateral neck dissection on operation day, postoperative month 1 and postoperative month 3 among the robotic, endoscopic and open approach.
5,640 studies on the registry are indexed under Pain, Postoperative; 1,230 are open to participants now.
This study's planned enrollment of 600 is above the median of 102 across 683 observational studies indexed under Pain, Postoperative.

Counted across the registry records on this site, refreshed daily.
Patients with FNA proven differentiated thyroid cancer and metastatic lateral lymph nodes, underwent lateral neck dissection via robotic, endoscopic or open approach. Patients were well informed about the potential benefits and risks of robotic, endoscopic and open approach. Patient consented for us to use perioperative data.
