Clinical Study of 16 Cases of Secondary Hyperparathyroidism

Total parathyroidectomy and autotransplantation of parathyroid glands were performed in 9 patients and subtotal parathyroidectomy was performed in 7 patients with secondary hyperparathyroidism resulting from chronic renal failure. The detection rate of enlarged parathyroid glands by preoperative imaging was 38% by computed tomography, 77% by ultrasonography, and 44% by MIBI scintigraphy. The removal rate of parathyroid glands by operation was 89%.In order to remove supernumerary glands, we need to improve operation methods. It is appropriate that the resection of pre- and paratrachial tissues should be performed in addition to the simple parathyroidectomy in cases in which not all parathyroid glands can be found.
