Key result
BMI ≥23 kg/m2 (HR 5.34, P=0.008) and bilateral central neck dissection (HR 14.92, P=0.028) were independent risk factors for prolonged operative time in robotic total thyroidectomy.

What factors are associated with prolonged operative time in patients undergoing robotic thyroidectomy?
Hazard Ratio: 5.34
p-value: p=0.008
Body habitus (BMI ≥23 kg/m2) and clinical nodal status requiring central neck dissection significantly prolong operative time in robotic thyroidectomy.
Background The purpose of this study was to evaluate factors related to operative time in robotic thyroidectomy. Methods We retrospectively analyzed 240 patients who underwent robotic thyroidectomy. The total thyroidectomy cases and lobectomy cases were both categorized into those with long operative times (LOTs; upper 25% of cases) and those with short operative times (SOTs; lower 25%). Results Among the total thyroidectomy cases, body mass index (BMI) ≥23 kg/m 2 (hazard ratio [HR] 5.34; P = .008) and bilateral central neck dissection (CND; HR 14.92; P = .028) were more frequent in the LOT group in multivariate analysis. Among the lobectomy cases, BMI ≥23 kg/m 2 (HR 12.92; P = .003) and unilateral CND (HR 21.38; P = .017) were the only independent risk factors for prolonged operative time. Conclusion Body habitus and clinical nodal status in the central compartment should be considered in deciding the indications for robotic thyroidectomy.

Song et al. (2017) conducted a cohort in Robotic thyroidectomy (n=240). Body mass index (BMI) ≥23 kg/m2 vs. BMI <23 kg/m2 was evaluated on Long operative time (upper 25% of cases) in total thyroidectomy (HR 5.34, p=0.008). BMI ≥23 kg/m2 (HR 5.34, P=0.008) and bilateral central neck dissection (HR 14.92, P=0.028) were independent risk factors for prolonged operative time in robotic total thyroidectomy.
