Abstract:
Purpose: To compare the clinical efficacy of ultrasound-guided percutaneous microwave ablation (MWA) and parathyroidectomy for primary hyperparathyroidism. Methods: In an observational retrospective study, we compared the outcomes in patients with primary hyperparathyroidism who underwent ultrasound-guided MWA with the outcomes in those who underwent surgical resection (SR). The primary outcome was cure rate. Secondary outcomes were the rate of complications, and the difference of the treatment parameters of two treatment methods. Propensity-score matching was used to assemble a cohort of patients with similar baseline characteristics. Results: Among 108 patients who met inclusion criteria, 28 patients who underwent ultrasound-guided MWA (MWA group) and 28 who underwent SR (SR group) had similar propensity scores and were included in the analyses. There was no significant difference in the cure rate between MWA group and SR group (82.1% vs. 89.3%, p = .705). Patients who underwent MWA had significantly less estimated blood loss and shorter surgical time than those who underwent SR (p < .001). The incidence of side effects and complications was comparable between MWA group and SR group (21.4% vs. 25%, p = .752). Conclusions: MWA and SR provided comparable short-term results in terms of cure rate and complications in treatment of primary hyperparathyroidism. Ultrasound-guided percutaneous MWA is a promising and minimally invasive method for primary hyperparathyroidism.
