title: [Primary hyperparathyroidism--a 16-year material from a central hospital].
abstract: BACKGROUND
  In Norway, population 4.3 million, approximately 160 patients a year have undergone surgery for primary hyperparathyroidism during the last ten years. Previous reports are rare.
  
  
  METHODS
  A retrospective analysis of all patients operated for primary hyperparathyroidism during 16 years at Vestfold Hospital, which serves a population of 200,000. Late recurrences and persisting hypocalcaemia were evaluated with laboratory tests median eight years after surgery.
  
  
  RESULTS
  104 patients were operated (88 females and 16 males; median age 64 years, range 22-78). Adenomas were found in 88 patients, of which four had double adenomas, and hyperplasia in 16 patients. Three patients died postoperatively, within 30 days, all of them high-risk patients. Two patients were reoperated because of bleeding. In one patient an infection was drained. Median hospital stay was five days. Two patients had persisting hypercalcaemia; eight patients needed permanent vitamin D substitution. Four recurrences were detected. Normocalcaemia was achieved in 91 patients (90%).
  
  
  CONCLUSIONS
  Surgical treatment leads to normocalcemia in 90% of patient, but is not risk-free in severely ill patients. To assess the true benefit of the operation for the individual patient, better preoperative mapping of symptoms and better follow-up protocols should be implemented.
