Outcomes analysis of intraoperative adjuncts during minimally invasive parathyroidectomy for primary hyperparathyroidism

BackgroundThe 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).MethodsA 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.ResultsThere 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).ConclusionsioPTH facilitates successful minimally invasive parathyroidectomy (MIP) when compared with MIRP and provides cure rates similar to BNE.
