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 assess the clinical efficacy of percutaneous transplantation of parathyroid glands into the subcutaneous tissue of the epigastrium for treating malignant secondary hyperparathyroidism (SHPT). MethodsThe clinical data of the patients with SHPT who were treated by puncturing the subcutaneous tissue of the epigastrium and transplanting parathyroid glands in the Xuzhou Central Hospital from January 2020 to June 2022 were collected retrospectively. The preoperative and postoperative parathyroid hormone (PTH) level, calcium ion concentration, alkaline phosphatase (ALP) level, and phosphorus ion concentration, as well as postoperative follow-up results were analyzed. The data analysis was conducted using SPSS 23.0 software, with a testing level of 0.01. ResultsA total of 21 patients successfully underwent this surgery, including 12 males and 9 females, with a median age of 48 years old and a range of 32–71 years old. The dialysis time was (8.62±2.27) years, and 12 patients had hypertension, 9 patients had anemia, 17 patients had bone pain, and 11 patients had skin itching. On day 1 after treatment, the PTH level decreased from (1 893.23±539.30) ng/L to (5.99±3.50) ng/L (P<0.001), the calcium ion concentration decreased from (2.52±0.31) mmol/L to (2.24±0.35) mmol/L (P=0.003), and the phosphorus ion concentration decreased from (2.25±0.71) mmol/L to (1.76±0.38) mmol/L (P=0.006) as compared with the values before surgery. Although the ALP level decreased from (321.78±151.01) U/L to (229.32±89.32) U/L, there was no statistically significant difference (P=0.016). Among the 12 patients with hypertension before surgery, 6 patients improved and reduced the use of antihypertensive drugs after surgery; among the 9 patients with anemia, 3 patients improved before discharge; 17 patients with bone pain showed markedly relief before discharge; and 9 patients with skin itching improved before discharge. There were no complications such as hoarseness, choking cough when drinking water, or incision infection after the operation. All 21 patients were followed up for 6–12 months. The parathyroid hormone levels of the 21 patients all dropped to the normal level within 12 months after the operation. Among them, 3 patients recovered to the normal level at the 3rd month after the operation, 16 patients recovered to the normal level at the 6th month after the operation, and 2 patients recovered to the normal level at the 12th month after the operation. The time to return to the normal level was (5.86±2.70) months. No serious complications occurred in all patients, and there was no recurrent case during follow-up period. Conclusion From the analysis results of our study, parathyroid autotransplantation into the subcutaneous tissue of the epigastrium via puncture is a safe and effective method for patients with SHPT.
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 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.
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.
Secondary and tertiary hyperparathyroidism are common complications in patients with chronic kidney disease, especially in end stage renal disease. Surgery is an important method for the treatment of secondary and tertiary hyperparathyroidism. The American Association of Endocrine Surgeons Guidelines for the Definitive Surgical Management of Secondary and Tertiary Renal Hyperparathyroidism is the first evidence based guideline focus on renal hyperparathyroidism surgical management. Recommendations using the best available evidence by a panel of 10 experts in secondary and tertiary renal hyperparathyroidism constructed this guideline, which provides evidence-based, individual and optimal surgical management of secondary and tertiary renal hyperparathyroidism. This paper made a guideline interpretation on the indications of surgery, imaging examination, preoperative and perioperative management, relevant evaluation and treatment during perioperative period, and intraoperative parathyroid hormone monitoring during operation, and so on.
ObjectiveTo explore and discuss the effects of lanthanum carbonate on serum calcium and phosphorus of continuous ambulatory peritoneal dialysis (CAPD) patients with chronic renal failure receiving calcitriol pulse therapy due to secondary hyperparathyroidism (SHPT). MethodsCAPD patients caused by SHPT in peritoneal dialysis centre of the Qingdao Municipal Hospital of Eastern Hospital from March to June, 2013 were selected and randomly divided into two groups (lanthanum carbonate group and calcium carbonate group). The lanthanum carbonate group were treated with oral lanthanum carbonate and calcitriol pulse therapy, while the calcium carbonate group were treated with calcium carbonate and calcitriol. Change of levels of serum calcium, phosphorus and iPTH were observed and statistic analysis was conducted using SPSS 17.0. ResultsA total of 40 CAPD patients were included, 20 cases in each group. After 12-week treatment, levels of serium phosphate (t=5.095, P=0.000) and iPTH (t=1.225, P=0.000) in the lanthanum carbonate group were significantly lower than those before treatment. The levels of serum calcium (t=1.127, P=0.001) and phosphate (t=2.035, P=0.000) in the lanthanum carbonate group were significantly lower than those in the calcium carbonate group (P < 0.05). ConclusionLanthanum carbonate serves as a useful approach to improve hypercalcemia and the hyperphosphatemia in CAPD patients receiving calcitriol pulse therapy due to SHPT.
