Despite several options for the extent of parathyroidectomy in secondary and tertiary hyperparathyroidism, <5% of patients are referred for surgical procedures. The purpose of this study was to identify beneficial outcomes of near-total parathyroidectomy (NTPTX) in this population. NTPTX (a vascularized parathyroid remnant is left in situ, and cryopreservation is performed) was completed in 142 patients with secondary (n = 93 patients) and tertiary (n = 49 patients) hyperparathyroidism, and was guided by intraoperative intact PTH (IOPTH). One hundred thirty-six of 142 patients (96%) remain cured at a mean follow-up time of 23 ± 26 months. Six patients had missed mediastinal (n = 4 patients) or cervical (n = 2 patients) parathyroid glands. No patient required re-resection of a cervical parathyroid remnant. One patient had hypoparathyroidism and underwent autografting with cryopreserved tissue. NTPTX reduced parathyroid mass (4526 ± 4515 mg to 77 ± 56 mg) and IOPTH (1171 ± 1252 pg/mL to 101 ± 127 pg/mL). Fatigue and musculoskeletal pain resolved promptly after operation. Patients with tertiary hyperparathyroidism experienced an improvement in bone density of 3.6% per year. NTPTX achieved full healing of extremity ulcers without amputations or perioperative death in 22 patients with calciphylaxis. NTPTX effectively treats secondary and tertiary hyperparathyroidism in >95% patients. IOPTH monitoring and cryopreservation are valuable procedural adjuncts. Limb salvage in calciphylaxis, symptomatic relief, and improved bone density are substantial benefits to recommend this procedure to patients with renal hyperparathyroidism.
