BACKGROUND: In Norway, population 4.3 million, approximately 160 @entity1 a year have undergone surgery for @entity459 during the last ten years. Previous reports are rare. MATERIAL AND METHODS: A retrospective analysis of all @entity1 operated for @entity459 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 @entity1 were operated (88 females and 16 males; median age 64 years, range 22-78). @entity652 were found in 88 @entity1 , of which four had double @entity652 , and @entity1373 in 16 @entity1 . Three @entity1 died postoperatively, within 30 days, all of them high-risk @entity1 . Two @entity1 were reoperated because of @entity548 . In one @entity1 an infection was drained. Median hospital stay was five days. Two @entity1 had persisting hypercalcaemia; eight @entity1 needed permanent @entity560 substitution. Four recurrences were detected. Normocalcaemia was achieved in 91 @entity1 (90%). INTERPRETATION: Surgical treatment leads to normocalcemia in 90% of @entity1 , but is not risk-free in severely ill @entity1 . To assess the true benefit of the operation for the individual @entity1 , better preoperative mapping of symptoms and better follow-up protocols should be implemented.
