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.
ObjectiveTo study the regularity of cervical lymph node metastasis in papillary thyroid carcinoma and a reasonable surgical method. MethodsThe clinical data of 221 cases of papillary thyroid carcinoma treated in this hospital between September 2004 and September 2009 were analyzed retrospectively. ResultsThere were 32 cases treated with total thyroidectomy, 189 patients with subtotal thyroidectomy. Two hundred and two patients with unilateral thyroid carcinoma and 19 patients with bilateral thyroid carcinoma were diagnosed by pathology. The diameter of tumor was 0.2-8.0 cm with an average of 3.5 cm. The amicula invasion was found in 50 cases and mulifocality in 33 cases. The numbers of lymph node dissection were 10-24 with an average of 14.3 in unilateral. The total lymph node metastasis rate was 37.56% (83/221), the lymph node metastasis rate was 33.94% (75/221) in the Ⅵ region, and which was 18.10% (40/221) in the Ⅱ+Ⅲ+Ⅳ region. The rate of cervical lymph node metastasis markedly increased in the patients with the primary tumor diameter gt;1.0 cm, amicula invasion, multifocality, or age gt;45 years in the Ⅵ region and ipsilateral of Ⅱ+Ⅲ+Ⅳ region (Plt;0.05). ConclusionsIn patients with thyroid papillary carcinoma, the most common lymph node metastasis happened in the Ⅵ region, next in the Ⅱ+Ⅲ+Ⅳ region. Lymph nodes of the Ⅵ region should routinely be dissected in the first surgery, the lymph nodes of the Ⅱ+Ⅲ+Ⅳ region should be dissected when the tumor diameter gt;1.0 cm, amicula invasion, multifocality or ultrasonic, CT, and other imaging examinations demonstrated cervical lymph node metastasis.
