[Reoperations in persistent and recurrent secondary hyperparathyroidism].

Among 181 patients who had been surgically treated in the Department of Surgery, Mainz University, for secondary hyperparathyroidism between 1975 and 1986, 33 had to be reoperated because of persistent or recurrent disease or because of failing autotransplanted tissue after total parathyroidectomy and autotransplantation. In 17 patients 26 reoperations had to be performed in the neck; in 9 patients, 3 of whom are already included in the group mentioned before, autotransplanted tissue had to be reduced eleven times. In another 10 patients autologous, cryopreserved tissue was replanted. 15 of the 17 patients reoperated in the neck became normocalcaemic, postoperatively, as well as 7 out of 9 patients in whom the autotransplanted tissue had been partially taken off. The results with replantation of cryopreserved tissue are being published in a separate article in this volume.
