Abstract:
:The role of preoperative localization tests in patients undergoing initial neck exploration for hyperparathyroidism (HPT) is controversial. The use of parathyroid ultrasonography (US) in 46 patients (7 men, 39 women; mean age: 60 years) who underwent initial neck exploration for hypercalcemia and who had the diagnosis of HPT confirmed at surgery is reported. At surgery, a single adenoma was found in 40 patients and multiple hyperplastic glands in 6 patients. Of the 40 adenomas, only 22 (58%) were localized to the correct side by the preoperative US, and only 5 of 18 hyperplastic glands (28%) were correctly localized. The rates of false-positive and false-negative results were 10% and 46%, respectively. The sensitivity of parathyroid US was 54%, the specificity 90%, and the accuracy 70%. The low sensitivity and accuracy and the high rate of false-negative test results that were observed suggest that there is no role for the routine use of parathyroid US in patients undergoing initial neck exploration for HPT.
