[Results and complications of parathyroidectomy in secondary hyperparathyroidism].
Retrospective study was performed to measure the results of parathyroidectomy in patients with secondary hyperparathyroidism. From 1987 to 2000, 48 patients underwent surgery for secondary hyperparathyroidism. There were 30 of 48 patients on haemodialysis treatment, and 11 patients were in pre-dialysis stage. Parathyroidectomy was performed after successful kidney transplantation in 4 cases. Indication of the surgery was extremely elevated serum level of parathyroid hormone (at least 10 fold elevation), which was resistant for the conservative medical therapy. Subtotal parathyroidectomy (3 1/2) was performed in 30 patients. Five patients underwent total parathyroidectomy and autotransplantation. Only 2 or 3 parathyroid glands have been removed in 13 patients. Haematoma occurred in 3 cases after parathyroidectomy. Recurrent nerve injury or septic complication did not occur. Two patients died in the early postoperative period due to cardiac failure. Tetania was noted in 2 patients after surgery. Permanent postoperative hypocalcaemia (over 6 months) occurred in 3 cases. Persistent hyperparathyroidism was diagnosed in 5 patients. In these patients 2 parathyroid glands were removed during the primary operation. Recurrent hyperparathyroidism was detected in 2 patients. Subtotal parathyroidectomy was carried out in these cases previously. At the reoperation for persistent and recurrent hyperparathyroidism, total parathyroidectomy and autotransplantation was performed. Serum alkaline phosphatase level and serum parathyroid hormone value decreased after surgery, except those patients with persistent hyperparathyroidism. Bone pain decreased in 96% of the cases and pruritus decreased in 92% of the patients after parathyroidectomy. Soft tissue calcification showed improvement in 45% of cases. In conclusion, the subtotal parathyroidectomy or total parathyroidectomy with autotransplantation cause a rapid decrease of PTH level and the improvement of the clinical symptoms in patients with medical treatment resistant secondary hyperparathyroidism. Persistent hyperparathyroidism occurs in those cases when inadequate parathyroidectomy was performed.
