    BackgroundSubtotal parathyroidectomy (SP) and total parathyroidectomy (TP) with autotransplantation (TPai) are the most commonly adopted operations for the treatment of secondary hyperparathyroidism (2HPT). TP without autotransplantation had previously been confined to patients with advanced dialytic vintage, not eligible for kidney transplantation. Over the years, the procedure has gained more widespread use, but there is no precise knowledge on the immediate and long-term effects.MethodsThe authors analyzed the immediate and long-term results of TP without autotransplantation, that is after the systematic removal of at least four glands in 20 patients operated for 2HPT, which were compared with results from TPai in an equal number of cases.ResultsAn improvement of the typical clinical symptoms was found in every patient undergoing surgery, and a significant reduction in intact PTH (iPTH) serum levels was achieved. Immediate normalization of iPTH level was observed in 11/20 TP cases, hypoparathyroidism in 4/20 and persistent HPT in 5/20 cases. One year of follow-up showed a slight increase in hypoparathyroidism, with 1/20 (5%) recurrence of the disease. One-year TPai results showed a similar percentage of euparathyroidism, as well as a higher longterm recurrence rate (4/20, 20%), although values do not reach statistical significance.ConclusionsTP may still be considered the operation of choice in patients with aggressive forms of 2HPT or of advanced dialytic vintage, with no access to renal transplantation, because of its low recurrence rate (5%). Post-operative aparathyroidism is rare, while hypoparathyroidism and hypocalcemia can be well controled by medical treatment.
