Robotic thyroidectomy operative time is influenced by patient body mass index (BMI) and central neck dissection (CND). Higher BMI and extensive CND correlate with longer operative times, impacting surgical planning.

Area of Science:

  • Surgical Oncology
  • Endocrine Surgery
  • Minimally Invasive Surgery

Background:

  • Robotic thyroidectomy is an increasingly utilized surgical approach.
  • Understanding factors influencing operative time is crucial for optimizing surgical efficiency and patient outcomes.

Purpose of the Study:

  • To identify patient-specific and surgical factors associated with prolonged operative times in robotic thyroidectomy.
  • To analyze these factors separately for total thyroidectomy and lobectomy procedures.

Main Methods:

  • Retrospective analysis of 240 patients undergoing robotic thyroidectomy.
  • Categorization of cases into short operative times (SOTs; lower 25%) and long operative times (LOTs; upper 25%).
  • Multivariate analysis to identify independent risk factors for prolonged operative time.

Main Results:

  • For total thyroidectomy, body mass index (BMI) ≥23 kg/m² (HR 5.34) and bilateral central neck dissection (CND) (HR 14.92) were significantly associated with LOTs.
  • For lobectomy, BMI ≥23 kg/m² (HR 12.92) and unilateral CND (HR 21.38) were independent risk factors for prolonged operative time.
  • Statistical significance was observed for all identified risk factors (P < .05).

Conclusions:

  • Patient body habitus (BMI) and central compartment nodal status (CND) are critical factors influencing robotic thyroidectomy duration.
  • These factors should be carefully considered when determining patient eligibility and planning surgical strategy for robotic thyroidectomy.
