title: [Lessons from reoperations in 55 patients with primary hyperparathyroidism].
abstract: On the basis of 70 re-operations in 55 patients (34 women, 21 men, median age 58 [43-83] years) suffering from primary hyperparathyroidism the reasons for failure of the first operations were analysed. The main reasons were inadequate exploration of the neck (failure to identify all four glands), failure to recognize multiple gland involvement, or inadequate resection in cases where more than one gland was affected. An abnormally situated gland was a less common cause, as shown by the fact that 41 out of the 73 glands removed at the last re-operation were situated in the normal position or in its immediate vicinity; in 20 cases the surgeon had failed to recognise multiple gland disease. Next in order of importance were anatomical variations in the location (32 out of 73 tumours) or the number of the glands (9 patients with hyperplasia of 5 glands). At the re-operations 89% of the parathyroid tumours were found in the neck region or would have been accessible from the neck at the time of the first operation. Overall, the hypercalcaemia was permanently rectified in 96.6% of the patients. During the last 10 years 94% of patients have been normocalcaemic postoperatively, thanks mainly to the re-implantation of autologous parathyroid tissue, preserved by low-temperature storage. The incidence of permanent unilateral recurrent nerve paresis attributable to the re-operations was 6%.
