A prospective surgical outcome study assessing the impact of parathyroidectomy on symptoms in patients with secondary and tertiary hyperparathyroidism.
BACKGROUND
To assess the impact of surgery on preoperative symptoms in secondary (2 degrees ) and tertiary (3 degrees ) hyperparathyroidism (HPT) compared with primary (1 degrees ) HPT.


METHODS
Twenty-two patients with 2 degrees HPT and 10 with 3 degrees HPT were enrolled. Age-matched patients, 32 with 1 degrees HPT and 32 with thyroid disease were enrolled for comparison. An outcome questionnaire documented symptoms expressed as the median symptom index score (MSIS) preoperatively and at days 7 and 3 and 12 months postoperatively.


RESULTS
Preoperatively, the MSIS for the groups with 3 degrees, 2 degrees, and 1 degrees HPT and thyroid disease was 225, 572, 372, and 146, indicating that patients with HPT were more symptomatic than those in the thyroid group (P<.05). Patients with 1 degrees HPT had a decrease in their MSIS at day 7 (195, P<.05) and at 3 and 12 months (159 and 156). Patients with 3 degrees HPT also had a decrease in their MSIS over time. Patients with 2 degrees HPT had a decrease in their MSIS at day 7 (469, P<.05); however, they remained more symptomatic at 3 and 12 months (410 and 355).


CONCLUSIONS
Parathyroidectomy reduces many of the preoperative symptoms in HPT. Patients with 1 degrees and 3 degrees HPT have a similar resolution of their symptoms. Patients with 2 degrees HPT have an improvement in many of their symptoms, although they remain more symptomatic at 1 year.
