Study summary

To develop and validate a structured scoring tool (robotic thyroidectomy assessment score, RTAS) for assessing and quantifying surgical performance in robotic thyroidectomy (RT).

Read the detailed description

This study was conducted in two phases. In the first phase, the content development and validation phase, the key elements of robotic thyroidectomy with central neck dissection were broken down into 9 key steps for assessing the technical skills required to complete the procedure: creating the surgical area, exposing the thyroid gland, dissecting the upper pole of the thyroid gland with preservation of the superior laryngeal nerve (SLN), identifying and protecting the upper pole of the parathyroid glands, protecting the retractor laryngeal nerve (RLN), identifying and protecting the lower pole of the parathyroid glands, removing the thyroid, dissection of the central neck region and hemostasis.

The Delphi method was used for content validation of the 9 key steps. Each item was described using a Likert scale: 1 for worst and 5 for best. Experts were invited to evaluate each of the 9 key steps in terms of the description of the items and the agreement of the items with the assigned scores. Based on the Delphi method, the opinions of the experts were collected and consensus on the entry was indicated by determining that a content validity index (CVI) > 0.75 (CVI measure: the proportion of experts who scored each entry 4 or 5. Consensus is considered to have been reached when the CVI reaches 0.75. For entries where consensus was not reached entries were revised to reflect any changes suggested by the expert group and the revised scoring system was recirculated for reassessment. This process is repeated until all entries have reached consensus.

In the second phase of the study, the structural validation phase, two consecutive 50 robotic by the same operator after a learning curve were scored. The aim was to analyze whether the scoring system developed in the first phase could assess operator progress and steps for improvement. In addition, the time taken to complete the procedure was recorded and compared. It was also analyzed whether there were any differences in the baseline (tumor size, location, age, gender, etc.) of the patients in the two groups (1st 50 cases and 2nd 50 cases).

What researchers measure

Primary outcomes

  1. Number of participants with recurrent laryngeal nerve injury

    impaired vocal cord mobility confirmed by postoperative laryngoscopy

    Time frame: through study completion, an average of 1 year

  2. Number of participants with hypoparathyroidism

    a postoperative parathyroid hormone level of less than 10 pg/ml

    Time frame: through study completion, an average of 1 year

  3. Operative time

    operative time was defined as the duration from incision to closure, and was collected from anesthesia record sheet

    Time frame: through study completion, an average of 1 year

  4. Score for surgical competence

    score evaluated by the proposed assessment system

    Time frame: at the end of robotic thyroidectomy

Secondary outcomes

  1. hospitalization

    days of hospitalization

    Time frame: through study completion, an average of 1 year

  2. degree of pain

    pain intensity was assessed using a standard visual analogue score, with a score of 0 to 10 corresponding to no pain to the most severe pain

    Time frame: approximately 4 hours after surgery and on postoperative day 1

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Dec 2024 (actual). Primary completion is estimated for Dec 2027, 36 months after the start.

Of 103 non-industry observational studies under Thyroid Neoplasms, half reached primary completion within 71 months of starting (the median), counting those still running; a quarter within 24 and three quarters within 311. This study's planned 36 months is below that.

Counting every sponsor, half of 112 studies reached it within 63 months; a quarter within 26 and three quarters within 311.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 7, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
