title: [Incidence of recurrence in long-term follow-up of 100 patients after surgery for primary hyperparathyroidism].
abstract: The percentages for recurrence or persistence of hyperparathyroidism after operation for pHPT vary between 3 and 7% according to the pertinent literature. These groups of authors have a broad experience based on a large number of patients treated. At our institute we have operated for pHPT an average of 5 patients per year. Given our limited experience we reexamined 100 consecutive patients which were operated for pHPT between 1968 and 1988 in order to determine our own rate of recurrence. The rate for persistent or recurrent hyperparathyroidism was at 8% slightly higher than in the literature reviewed. When reexamining the patients we took the history concerning the preoperative symptomatology and its postoperative course. Furthermore we compared a radioimmunoassay measuring the midmolecule region of the parathyroid hormone with a immunochemiluminometric assay determining the intact and biologically active hormone regarding sensitivity and specificity. The results are presented and compared with the literature reviewed.
