RESUMO
BACKGROUND: The aim of this study was to determine whether minimally invasive radioguided parathyroidectomy (MIRP) and intraoperative parathyroid hormone-guided parathyroidectomy (ioPTH) have equivalent intermediate-term outcomes in primary hyperparathyroidism (PHPT). METHODS: A retrospective study of 244 patients who underwent parathyroidectomy for PHPT in a 25-month time period was conducted. Patients who either underwent MIRP- or ioPTH-guided parathyroidectomies were included. The primary outcome was persistent disease. Conversion to bilateral exploration, complications, and multigland disease (MGD) were secondary outcomes. RESULTS: There was 1 MIRP patient and no ioPTH patients who had persistent disease. The ioPTH group had more conversions to a bilateral exploration (bilateral neck exploration [BNE]) (3.7% vs 13%, P = .024). In the MIRP group, no patients were found to have MGD. In the ioPTH group, 7 patients with double adenomas and 6 patients with MGD were found (0 vs 13, P = .0028). CONCLUSIONS: ioPTH facilitates successful minimally invasive parathyroidectomy (MIP) when compared with MIRP and provides cure rates similar to BNE.
