Objective To investigate the clinical diagnosis and treatment for primary hyperparathyroidism with concomitant thyroid diseases. Methods The clinical data of 40 cases diagnosed as primary hyperparathyroidism with concomitant thyroid diseases including manifestation, preoperative qualitation and localization, and surgical treatment and results were retrospectively analyzed. Results The 40 cases were composed of 4 parathyroid adenomas with thyroid papillary carcinomas, 28 parathyroid adenomas with nodular goiters, 6 parathyroid adenomas with thyroid adenomas, 1 parathyroid hyperplasia with nodular goiter, and 1 parathyroid carcinoma with thyroid adenoma. The diagnostic sensitivities of localization for primary hyperparathyroidism with concomitant thyroid diseases by ultrasound, by computerized tomography (CT), and by radioisotope (99Tcm) scanning were 82.5% (33/40), 80.0% (32/40) and 90.0% (36/40), respectively, and the combined sensitivity was 97.5% (39/40). The surgical treatments included resection of parathyroid adenoma with subtotal thyroidectomy in 34 cases, resection of parathyroid adenoma with total thyroidectomy in 3 cases, bilateral exploration of parathyroid with subtotal thyroidectomy in 1 case, and unilateral parathyroidectomy with thyroidectomy and neck lymphonodes clearance in 2 cases. ConclusionFor primary hyperparathyroidism with concomitant thyroid diseases, the sensitivity of preoperative localization could be raised by combining ultrasound, CT with radioisotope scanning, and surgical resection is the main treatment, which includes the main operation of resection of parathyroid adenoma with subtotal or total thyroidectomy.
Objective To evaluate the diagnostic significance and to analyze reasons of false negative cases forpreoperative ultrasonography， 99Tcm-sestamibi scintigraphy （MIBI scintigraphy）， and CT in primary hyperparathyroidism（PHPT）. Methods Clinical data of 69 patients with PHPT， who underwent operation in Affiliated Shengjing Hospital of China Medical University between Jan. 2003 and Aug. 2012 were retrospectively analyzed. Results There were 76 parathyroid lesions in 69 PHPT patients proved by operation and pathology， including 58 cases of parathyroid adenoma with 60 lesions， 7 cases of parathyroid hyperplasia with 11 lesions， and 4 cases of parathyroid carcinoma with 5 lesions. The sensitivity of ultrasonography， CT， and 99Tcm-MIBI scintigraphy were 81.94% （59/72）， 61.76% （21/34）， and 69.57% （16/23）， the accuracy of 3 kinds of tests were 78.67% （59/75）， 61.76% （21/34）， and 66.67% （16/24）， the positive predictive value were 95.16% （59/62）， 100% （21/21）， and 94.12% （16/17） respectively. There was significant differ-ence only between ultrasonography and CT in sensitivity （P=0.03）， no other significant difference was found （P＞0.05）.Conclusions Ultrasonography is complementary to 99Tcm-MIBI scintigraphy， but CT has little significance in diagnosis of PHPT. Both of ultrasonography and 99Tcm-MIBI scintigraphy should be used before operation routinely to localize parathyroid lesions.
ObjectiveTo analysis the clinical symptoms, diagnosis, and treatment of primary hyperparathyroidism (PHPT). MethodsA retrospective study was made in consecutive patients with PHPT who performed operation and had integral data between January 2004 to December 2012 in West China Hospital. ResultsThe 136 cases were composed of 52 cases (38.23%) bone types, 17 cases (12.50%) nephrocalcinosis, 7 cases (5.15%) skeletal and renal involvements, 24 cases (17.65%) asymptomatic primary hyperparathyroidism, and 36 cases (26.47%) combined with other clinical symptoms. The preoperative parathyroid hormone (PTH) levels were (106.20±88.88) pmol/L (6.91-390 pmol/L) and serum calcium were (3.12±0.66) mmol/L (2.15-5.77 mmol/L). The coincidence rate between the examinations preoperation and pathology:B type ultrasound was 75.00%, 99Tcm-MIBI scan was 85.29%, ultrasound and 99Tcm-MIBI combined with computerized tomography (CT) scan was 86.76%. Pathology presentation:129 patients (94.85%) were benign lesions, 7 cases (5.15%) were parathyroid carcinoma. Of the 129 patients, 114 cases (95.80%) were single parathyroid adenoma, 5 cases (4.20%) were multiple parathyroid adenoma or combined parathyroid hyperplasia, 10 cases (7.75%) were parathyroid hyperplasia. Of the patients, the PTH level decreased to below normal upper limit within 3 days after surgery in 124 cases (91.18%). One hundred and twenty-four cases (91.18%) were followed-up. The follow-up time was 6-112 months, a median follow-up time was 49 months. Twelve patients (8.82%) were lost to follow-up, 2 patients (1.47%) with carcinoma recurrence, the rest patients without recurrence and metastasis. Three patients (2.20%) with parathyroid carcinoma died. Of the 3 patients, 2 died of systemic metastasis of parathyroid carcinoma in 18 and 23 months after surgery, 1 died of cardiovascular accident in 19 months after surgery. ConclusionSurgical excision of the lesion parathyroid tissue is the most effective treatment for PHPT.
