Vague preoperative localization and ectopic parathyroid often lead to the failure of operation in primary hyperparathyroidism. From Jun 1989 to March 1998, 11 cases of primary hyperparathyroidism had been treated surgically in the general surgery department of our hospital. Of them, 10 cases were operated successfully with the pathological diagnosis of adenoma and one parathyroid removed was reported normal. Preoperative localization, the knowledge of ectopic parathyroids, careful exploration during operation and the postoperative medical treatment are important for the perioperative management. Postoperative followup has emphasized to benefit the treatment in primary hyperparathyroidism.
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.
Objective To analysis causes of reoperation for primary hyperparathyroidism and its clinical characteristics. Method The clinical data of the patients with primary hyperparathyroidism who had undergone reoperation from January 1993 to May 2017 were retrospectively analyzed. Results A total of 11 patients underwent reoperation were collected in the 226 patients with primary hyperparathyroidism. Of the 11 cases, 8 cases underwent twice operations, 2 cases underwent thrice operations, 1 case underwent quintic operation. After the initial operation, 3 cases were persistent diseases and 7 cases were recurrent diseases, 1 patient was not defined as the persistent or recurrent disease. The main clinical manifestations before the reoperation were fatigue, pain in joints, bones, or muscle. The reasons for reoperation included 3 cases of ectopic parathyroid lesions, 3 cases of recurrent parathyroid carcinomas, 1 case of enlarged operation extent for parathyroid carcinoma, 2 cases of regrowth of double parathyroid aedomas, 1 case of missing adenoma, 1 case of parathyroid hyperplasia. Among the location examinations, the 99Tcm-MIBI was most sensitivity (8/9). Eight cases were received reoperation on the original incision, and the remaining 3 ectopic parathyroid lesions on the new incision. After the reoperation, 2 patients were lost of follow-up, 1 patient died, and the remaining 8 patients had no recurrences during follow-up period. Conclusion A comprehensive approach with multiple imageology examinations which attribute to accurate location of lesions, experienced surgeons and well knowledge of parathyroid anatomy and embryology help to descend reoperation ratio and improve success rate of reoperation.
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.
目的 探讨原发性甲状旁腺功能亢进症(PHPT)的诊治经验。 方法 回顾性分析我院近15年间18例手术治疗的PHPT患者的临床资料。结果 初诊病例术前核素99Tcm-sestamibi扫描和B超检查阳性定位诊断率分别为100%（9/9）和88%（15/17）。18例均经手术治疗，其中1例为再手术病例。术后病理诊断甲状旁腺腺瘤13例，其中1例为双腺瘤； 甲状旁腺增生4例； 甲状旁腺腺癌1例。首次手术治愈率为88%（15/17）。2例甲状旁腺增生病例未治愈。再手术1例因损伤了单侧喉返神经致术后声音嘶哑。结论 术前核素99Tcm-sestamibi扫描和B超检查对制定手术方案有重要意义，大多数PHPT病例适合行单侧颈部探查术。甲状旁腺增生病例的手术治愈率低。
Objective To summarize the changes of serum vitamin D level in patients with primary hyperparathyroidism (pHPT), the correlation between vitamin D and clinical manifestations, and feasible pathogenesis of pHPT. Method The literatures related to vitamin D and pHPT in recent years were reviewed. Results The level of vitamin D was decreased in patients with pHPT. Vitamin D level was negatively correlated with the weight of parathyroid adenoma, parathyroid hormone and blood calcium level, and positively correlated with bone mineral density. Conclusions Vitamin D nutritional status affects the severity of symptoms, main biochemical indexes and main clinical complications of patients with pHPT. There are various reasons accounted for the decline of vitamin D level, and the specific pathogenesis needs to be further explored. For patients with pHPT, vitamin D should be supplemented carefully and appropriately before surgical operation.
ObjectiveTo compare the clinical effects of unilateral neck exploration (UNE) and direct minimally invasive parathyroidectomy (DPT) in the treatment of primary hyperparathyroidism (PHPT). MethodsThe clinical datas of 87 PHPT patients treated with intraoperative parathyroid hormone monitoring (IPM) -assisted UNE and DMIP in Guizhou Provincial People’s Hospital between January 2016 and December 2021 were analyzed retrospectively. ResultsThe average age of patients was (47.5±13.1) years, and there were 24 males (27.6%) and 63 females (72.4%). The pathological types of 87 cases were parathyroid adenoma in 78 cases (89.7%), atypical parathyroid adenoma in 5 cases (5.7%), parathyroid hyperplasia in 4 cases (4.6%), and no parathyroid carcinoma. Two cases (2.3%) developed recurrent laryngeal nerve injury, and 3 cases (3.4%) developed postoperative persistent hyperparathyroidism, of which 1 (1.1%) case underwent secondary surgery. There were no significant differences in the incidence of recurrent laryngeal nerve injury (2.0% vs. 2.6%, P=0.855) and postoperative persistent hyperparathyroidism between the UNE group and the DMIP group (2.0% vs. 5.3%, P=0.713). However, the intraoperative bleeding volume, operative time, hospitalization time, incision length, and pain score in the DMIP group were significantly less than or shorter than or lower than those in the UNE group (P<0.001). ConclusionThere is no significant difference in the efficacy between the DMIP and UNE in the treatment of PHPT, but DMIP can significantly shorten the operative time and hospitalization time, and reduce the trauma.
