Comparison of different parathyroid autograft project after total parathyroidectomy in patients with secondary hyperparathyroidism.

Objective: To evaluate the feasibility and efficacy of total parathyroidectomy followed by modified needle-quantified injection of parathyroid autograft compared with classic incision and transplantation.
Methods: We conducted a retrospective study of 171 patients with secondary hyperparathyroidism treated by hemodialysis or peritoneal dialysis. These patients were included in our study from April 2006 to December 2016, who had undergone total parathyroidectomies with autotransplantation. Patients were divided into classic incision for transplantation of parathyroid autograft group and modified needle-quantified injection group. Clinical and biochemical characteristics, including preoperative and postoperative intact parathyroid hormone levels were recorded and compared between two group patients.
Results: To compare the techniques of modified needle-quantified injection and classic incision and transplantation, pre- and postoperative biochemistry and length of operation was recorded and analyzed. Preoperative biochemistry was similarly in both groups. However, autograft function achieved was significantly faster in the group with modified needle-quantified injection compared with classic incision and transplantation (P = 0.03). Median time to parathyroid function regain was 3 months for injection compared with 7 months for classic incision. There was no remarkable difference in the recurrence rates between the two groups.
Conclusion: The modified needle-quantified injection of parathyroid tissue is a feasible and simple alternative to the more commonly used method of classic incision and transplantation.
