Prospective Evaluation of Total Parathyroidectomy and Autotransplantation for the Treatment of Secondary Hyperparathyroidism

Abstract

To evaluate the clinical effectiveness of total parathyroidectomy with autotransplantation for the treatment of hyperparathyroidism and the recurrence rate of hyperparathyroidism after this procedure. A prospective study of total parathyroidectomy and autotransplantation in 19 consecutive patients with severe secondary (renal) hyperparathyroidism. University hospital department of surgery. Nineteen patients operated on for the treatment of secondary hyperparathyroidism between March 1993 and March 1996. Eighteen had been receiving longterm hemodialysis, and 1 had a functioning renal graft. Total parathyroidectomy and autotransplantation of excised parathyroid tissue into the brachioradialis muscle of the arm opposite that in which the arteriovenous fistula had been placed for dialysis. Clinical and biochemical improvement, morbidity, mortality, and recurrence rates of hyperparathyroidism after the procedure. The conditions of 13 (72%) of 18 patients followed up improved, and the clinical and laboratory variables indicating secondary hyperparathyroidism returned to normal. One patient died 50 days after surgery. In 2 patients (10%), mild hypoparathyroidism developed, and in 1 patient (5%), persistent hyperparathyroidism developed and required reoperation. In 2 patients (10%), recurrent hyperparathyroidism developed, and 1 (5%) required reoperation. Total parathyroidectomy with autotransplantation effectively relieves the symptoms of hyperparathyroidism, and the recurrence rate of hyperparathyroidism is low. Because all procedures used resulted in good control of clinical and biochemical variables, the method used for the surgical treatment of secondary hyperparathyroidism depends on the surgeon's preference.
