Preliminary results of thyroid surgery from a tertiary comprehensive children's hospital

Thyroid nodules are rare in children and the risk of malignancy rate is considerably higher than in adults. In this study, we aimed to evaluate the patients who admitted to our hospital with thyroid nodules and underwent thyroid surgery examine the distributions of pathologies, changes in treatment protocols and results. Pediatric patients < 18-year-old, who presented with thyroid nodules and underwent thyroid surgery at our clinic between 2005 and 2018, were retrospectively examined. Demographic characteristics, complaints at presentation, ultrasonography findings, surgical method, histopathological results, and postoperative complications were evaluated. Data were compared between two time periods: before and after 2014. A total of 52 thyroid surgeries were performed on 45 patients with a female/male ratio of 3:1 and an average age of 14.1 ± 2.6 years. Differentiated thyroid carcinoma was detected in 12 (26.7 %) of the patients. The incidence of malignant tumors increased from 18.2 % to 26.7 % after 2014. Transient hypocalcemia was detected in 11 (21.1 %) patients. The risk of postoperative hypocalcemia was significantly increased in patients with bilateral resection ( p < 0.01). Parathyroid hormone level measured at 6–12 h postoperatively is useful in predicting hypocalcemia ( p = 0.001). No significant relationship was found between high body mass index and thyroid malignancy. Fine needle aspiration biopsy results were found to be significant in predicting malignancy ( p = 0.041). We assert the critical importance of vigilant postoperative monitoring for hypocalcemia, particularly following total thyroidectomy and completion thyroidectomy. Since the incidence of thyroid pathologies requiring surgical intervention in children is relatively low, we think that such cases should be performed in comprehensive pediatric hospitals where a multidisciplinary approach is adopted.
