PURPOSE: To re-examine our clinical practice and review strategy for treatment of primary hyperparathyroidism in patients with multigland disease.
METHODS: Retrospective analysis of 121 consecutive primary hyperparathyroidism (PHPT) patients who underwent surgery in a tertiary center between January 2010 and December 2014.
RESULTS: Of 121 patients with PHPT 87% had single gland adenoma (SGD) and 13% had multigland disease (MGD). The overall cure rate was 95.86%. MGD was more frequent in younger persons (<40y)(50% vs. 13.2%). All patients had SPECT-CT (Single Proton Emission Computerized Tomography) with 28% being SPECT-CT negative. Patients with MGD had a higher rate of persistent disease (13.33% vs. 2.83%). Specimen weight was <600mg in 75% of MGD patients. 67% of SPECT-CT negative patients had mild hypercalcemia (Calcium <2.75 mmol/L) which was more frequent in MGD patients (43% vs. 19%).
CONCLUSIONS: MGD patients were more likely SPECT-CT negative (40% vs. 25.4%) and benefit from bilateral neck exploration (BNE) (74%). However, most SPECT-CT negative patients still have a single adenoma. In our series MGD was more frequent in younger patients, more likely SPECT-CT negative, often associated with mild hypercalcemia and had a higher persistence rate than SGD. BNE is the operation of choice in young, SPECT-CT negative patients. If ultrasound parathyroids suggests a single large adenoma, minimally invasive parathyroidectomy with intraoperative PTH monitoring can be considered.
