Background:
Total parathyroidectomy for secondary hyperparathyroidism has low morbidity and mortality rates and requires a special workup in the preoperative period.
Methods:
Neck echography and technetium-99m-sestamibi scintigraphy were performed preoperatively. Cardiac echography, a thallium-201 myocardial perfusion scan, and cardiac catheterization were performed if necessary. During surgery, we removed all the parathyroid glands and the upper thymus and autotransplanted 100 mg of the smallest gland into the subcutaneous tissue of the forearm.
Results:
The success rate in three months after total parathyroidectomy was 91.7% without mortality. In the elderly (age ≤65 years, n = 35), bone pain, skin itching, general weakness, and insomnia improved three months after surgery, and grip strength increased significantly. One year after parathyroidectomy, the serum levels of Ca, P, alkaline phosphatase, and intact parathyroid hormone were all within the normal ranges. Except for the bone mineral density (BMD) of the radial distal one-third, the BMD of the lumbar spine (L2 to L4), femoral neck, femoral global, and radial global increased significantly. Furthermore, the bone density T-scores of the lumbar spine (L2 to L4), femoral neck, femoral global, radial distal one-third, and radial global improved significantly.
Conclusions:
After a meticulous preoperative workup, parathyroidectomy plus autotransplantation can be performed safely for the treatment of symptomatic secondary hyperparathyroidism in the elderly to improve their quality of life and decrease their incidence of bone fractures.
