Objective To summary the experience in diagnosis and managements for primary hyperparathyroidism（PHPT）. Methods The clinical data of 73 patients with PHPT who underwent parathyroidectomy in our hospital from Jan. 2003 to Dec. 2010 were analyzed retrospectively. Results There were 1 case of hyperplasia （1.4%）， 67 cases of adenoma （91.8%）， and 5 cases of adenocarcinoma （6.8%） among the 73 cases of PHPT. The common presentations involved with pain in bones and joints in 63 cases （86.3%）， pathologic fractures in 17 cases （23.3%）， osteoporosis in 59 cases （80.8%）， fatigue in 28 cases （38.4%）， abdominal pain in 4 cases （5.5%）， urolithiasis in 17 cases （23.3%）， malignant hypertension in 1 case （1.4%） who suffered multi-endocrine neoplasm （MEN）Ⅱa， and so on. The preoperativeserum parathyroid hormone （PTH） abnormally elevated in all 73 patients， and serum calcium abnormally elevated in 59 patients （80.8%）， and alkaline phosphatase abnormally elevated in 62 patients （84.9%） before operation. The positive rate of lesion locations by ultrasonography， CT， 99Tcm-sestamibi （MIBI） scan， and the combination of 3 kinds of tests were 82.8% （53/64）， 83.3% （20/24）， 90.2% （46/51）， and 91.8% （67/73） respectively， but 6 cases were not traced preop-eratively. Parathyroidectomy was conducted to all the cases， besides， regional neck lymphadenectomy was performed for those 5 adenocarcinoma cases. Tetany in 16 cases， hoarseness in 2 cases， acute pancreatitis in 1 case， acute left heart failure in 1 case were observed after operation. Sixty nine cases were follow-up for 3-72 months （average 17.3 months）. During the followed-up period， most of them were alleviated from bone pain （43 cases） and fatigue （18 cases）within 1 month. However， the recovery of PTH and serum calcium back to normality were relatively slow. One case ofadenoma recurred， 1 case of adenocarcinoma suffered lung metastasis， 1 case of adenocarcinoma survived for 37 monthsprior to death for postoperative lung and bone metastasis， the other cases （including 1 case of adenocarcinoma developed from adenoma） were still alive and had no metastasis or recurrence by the end of follow-up. Conclusions The symptoms of PHPT vary and lack of specificity， hence， the enhancement of knowledge to this disease and screenings conducted for parathyroid function and serum calcium will increase the rate of diagnosis. Parathyroidectomy is the effective management for PHPT， and preoperatively accurate position contribute to minimal exploration.
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.
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 research progress of the treatment of primary hyperparathyroidism (PHPT) in multiple endocrine neoplasm type 1 (MEN1). Method The literature about the treatment of PHPT in MEN1 in recent years was reviewed. Results When the symptoms of MEN1 related PHPT were obvious, surgery was an effective treatment. In addition to conventional total parathyroidectomy with autotransplantation and subtotal parathyroidectomy, less-than subtotal parathyroidectomy, and single gland excision had also been proved to be effective recently. Conclusions Combining the clinical manifestations with the actual involvement of the parathyroid of MEN1 related PHPT patients, personalized selection of appropriate timing and methods of parathyroidectomy can help MEN1 related PHPT patients obtain ideal parathyroid function and ensure the quality of life to the greatest extent.
ObjectiveTo summarize the research status of normocalcemic parathormone elevation after parathyroidectomy for patients with primary hyperparathyroidism. MethodsThe related literatures on normocalcemic parathormone elevation after parathyroidectomy were collected and reviewed. ResultsMost of the patients with primary hyperparathyroidism received radical treatment postoperation. NPE didn't predict failure of operation. The relationship between normocalcemic parathormone elevation and recurrent primary hyperparathyroidism remained to be further explored. Patients with normocalcemic parathormone elevation after parathyroidectomy had a higher risk of cardiovascular disease. Postoperative vitamin D and calcium supplementation could reduce the incidence of normocalcemic parathormone elevation. ConclusionsThe clinical significance of normocalcemic parathormone elevation is still unknown at present. Further researches of multicenter, huge sample, and long-term follow-up will be necessary.
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.
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.
