Surgery versus medical follow-up in patients with asymptomatic primary hyperparathyroidism: a decision analysis.

Objectives: To examine the cost-effectiveness of strategies for management of primary asymptomatic hyperparathyroidism: surgical strategies and medical follow-up versus surgery.

Design: We used a Markov state-transition decision-analytic model for an hypothetical cohort of 55-year-old women to compare with a lifetime horizon costs and effectiveness of bilateral neck exploration (BNE), unilateral neck exploration (UNE), video-assisted parathyroidectomy (VAP) and lifelong medical follow-up shifting for either BNE or UNE in case of disease progression.

Methods: Data on localization tests, complications and treatment efficacies were derived from a systematic review of the literature.
