Summary
This summary is machine-generated.

A new Thyroidectomy Difficulty Scale (TDS) accurately predicts operative times and complications. This validated tool aids surgeons in assessing thyroidectomy complexity and potential challenges during procedures.

Area of Science:

  • Endocrine Surgery
  • Surgical Outcomes Research
  • Patient Safety

Background:

  • Thyroidectomy is a common endocrine surgical procedure.
  • Objective assessment of thyroidectomy difficulty is crucial for surgical planning and training.
  • Existing methods for assessing surgical difficulty lack standardization.

Purpose of the Study:

  • To evaluate a novel Thyroidectomy Difficulty Scale (TDS).
  • Assess TDS inter-rater agreement among surgeons.
  • Correlate TDS scores with operative times and complication rates.

Main Methods:

  • A 20-point, four-item Thyroidectomy Difficulty Scale (TDS) was developed.
  • Two board-certified surgeons independently scored 119 thyroidectomy cases.
  • Statistical analyses included inter-rater agreement assessment, linear regression for operative time correlation, and multiple regression for independent predictors of operative time.

Main Results:

  • High inter-rater agreement was observed for TDS scores (87.4% within one point).
  • TDS scores significantly correlated with operative times (R2 = 0.36, p < 0.01).
  • Higher TDS scores were associated with increased operative times (≥14 score cases took 41.0% longer) and higher complication rates (p = 0.04).

Conclusions:

  • The Thyroidectomy Difficulty Scale (TDS) is a reliable and accurate tool for assessing surgical difficulty.
  • TDS scores effectively predict operative time and correlate with patient complications.
  • The TDS can aid in surgical planning, training, and risk stratification for thyroidectomy.
