Behandlingspraksis ved primær hyperparatyreoidisme

Abstract

A recent study found considerable regional differences in treatment of primary hyperparathyroidism in Norway. There is no consensus on specific indications for operation in these patients. We surveyed opinions among Norwegian endocrine surgeons and endocrinologists on the indications for surgical treatment of primary hyperparathyroidism. A questionnaire on preoperative evaluation, indications for surgery and treatment of patients with primary hyperparathyroidism was sent to the chief consultants of surgical departments that operated on parathyroid glands in 2005. The questionnaire was also sent to endocrinologists at the same hospitals. In 2006, 415 parathyroid gland operations were performed in 17 Norwegian hospitals, with a median of 18 operations per hospital. A total of 46 surgeons operated on the parathyroid glands, with a median of two surgeons per hospital. Hospitals differed with respect to preoperative evaluations and indications for operative treatment; but these differences did not coincide with regional differences in the frequency of parathyroid surgery. There was a good correlation between endocrine surgeons and endocrinologists on the indications for surgery in primary hyperparathyroidism, but neither group adhered unconditionally to the international guidelines for surgical treatment of patients with primary hyperparathyroidism. Patients in the hospitals that operated most frequently were initially diagnosed in a surgical department. Our survey did not reveal differences that could explain the large regional variations in the frequency of parathyroid surgery.
