Abstract
To analyze the short-term and long-term outcomes of the three operation methods in treatment of secondary hyperparathyroidism. Clinical data of 88 patients who underwent parathyroidectomy for secondary hyperparathyroidism from October 2004 to October 2014 were reviewed retrospectively. Patients were divided into three subgroups, including subtotal parathyroidectomy (group I), total parathyroidectomy with autotransplantation (group II) and intraoperative ⁹⁹Tc(m)-MIBI radioguided total parathyroidectomy with autotransplantation (group III). Their serum calcium, phosphorus, serum iPTH results in the pre-operation, short-term (≤ 6 months) and long term (> 6 months) of post-operation were collected and compared. The improvements of clinical symptoms together with the postoperative recurrence rate and the complication data were observed and analyzed. The symptoms of all patients were improved after the operation.The short-term postoperative serum calcium, serum iPTH and recurrence rate of Group I and group II were all not statistically significant. The short-term postoperative serum calcium, iPTH and recurrence rate of group III were significantly lower than those of group I and group II (P < 0.05). Postoperative serum phosphorus values of the three groups had no statistical difference. The operation time of group III was significantly shorter than that of group II ((77 ± 13) vs (108 ± 17) min, P < 0.05). The positive rates were more accurate in group III than in group II (98.5% vs 88.7%, P < 0.05). For the long term follow-up, the postoperative serum calcium, phosphorus, serum iPTH and recurrence rate of group I and group II were not statistically different. The postoperative recurrence rate of group III was lower than that of group I and group II (3.6% vs 31.6% and 21.4% respectively, P < 0.05). Total parathyroidectomy with autotransplantation has a good efficacy to treat secondary hyperparathyroidism. The intraoperative ⁹⁹Tc(m)-MIBI radioguided total parathyroidectomy with autotransplantation can find the ectopic and supernumerary glands to improve the success rate of operation. And it also can permit omission of frozen section to reduce the operative time.In the postoperative follow-up, the recurrence rate is low, so it is a safe and effective treatment.
