Abstract
Background: Little is known about perioperative outcomes after pediatric thyroidectomy. This study was performed to compare perioperative outcomes between children and adults undergoing thyroid cancer surgery using a nationwide inpatient database in Japan.
Methods: Using the Japanese Diagnosis Procedure Combination database, we identified patients aged 0 to 40 years with thyroid cancer who underwent thyroidectomy from July 2010 to March 2020. To compare the occurrence of in-hospital morbidities including local complications (e.g., recurrent laryngeal nerve paralysis, postoperative bleeding), duration of anesthesia, postoperative length of stay, and total hospitalization costs between children (0–18 years) and adults (19–40 years), we used multivariable logistic regression analysis for the occurrence of in-hospital morbidities and linear regression for other outcomes.
Results: For 16,016 eligible patients (666 children vs. 15,350 adults), no significant differences between the two groups were found in any in-hospital morbidity (5.4% vs. 5.9%; adjusted odds ratio [OR], 0.80; 95% confidence interval [CI], 0.57–1.14; P=0.23), local complications (5.0% vs. 5.5%; OR, 0.80; 95% CI, 0.55–1.15; P=0.22), recurrent laryngeal nerve paralysis (2.1% vs. 2.4%; OR, 0.78; 95% CI, 0.45–1.35; P=0.37), or postoperative bleeding (1.7% vs. 1.4%; OR, 0.99; 95% CI, 0.53–1.87; P=0.98). Children showed a longer duration of anesthesia (difference, 20 minutes; 95% CI, 13–27; P<0.001) and higher total costs (difference, 445 US dollars; 95% CI, 239–651; P<0.001) than adults.
Conclusion: This large nationwide cohort study showed no significant difference in perioperative complications between children and adults undergoing thyroid cancer surgery.
