Pediatric thyroidectomy in a "low volume" institution without protocolization: results and future horizons.

Objective: Pediatric thyroidectomy is an infrequent, complex surgery, with high risk of complications. Complication rates and oncological results of non-protocolized thyroidectomy in a secondary pediatric hospital were compared with those from reference institutions.

Materials and methods: A retrospective study of patients under 15 years old undergoing thyroidectomy ± cervical lymphadenectomy by low volume pediatric surgeons (<30 cervical endocrine surgeries annually) in a pediatric hospital from January 2010 to January 2020 was carried out.

Results: 11 patients undergoing 12 surgeries (mean age: 9.8 years; 63% female) were analyzed. Thyroid nodules were the main surgical indication (50%), and prevalence of genetic mutations was 45%. 1 patient had transient hypocalcemia, and there were 2 cases of transient recurrent laryngeal nerve neuropraxia (16.6%). No permanent complications were noted. 66.6% of pathological reports showed malignancy. Mean hospital stay was 2.35 days (range: 1.25-5), with an overall complication rate of 25%, similar to that reported by high-volume institutions. After a mean follow-up of 4 years, tumor recurrence has not been observed in any patient.

Conclusions: In our view, an experienced pediatric surgeon specialized in pediatric and neonatal general surgery - even if below the high volume threshold - acquires the skills required in pediatric thyroid surgery without an increase in morbidity and mortality. Perioperative management should be agreed and protocolized by the various specialists involved to improve results.
