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.
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.
ObjectiveTo explore therapeutic efficacy of parathyroidectomy (PTX) in treatment of secondary hyperparathyroidism (SHPT) in patients with end-stage renal disease.MethodsThe clinical data of 50 patients who underwent PTX for uremic SHPT from January 2016 to March 2018 were collected retrospectively. The changes of serum calcium, phosphorus, and intact parathyroid hormone (iPTH) before the surgery and 1 d, 7 d, 1 month, 3 months and 12 months after the surgery were analyzed. In addition, the improvement of clinical symptoms together with the postoperative recurrence and complications were observed.ResultsTen patients underwent the subtotal PTX (SPTX), 5 cases underwent the total PTX (TPTX), and 35 cases underwent the TPTX with autotransplantation (TPTX+AT). The PTXs were performed successfully in 47/50 (94.0%) patients. After the PTX, the bone pain and skin itching were alleviated, 3 cases had the temporary injury of recurrent laryngeal nerve and the hypoparathyroidism was found in 1 case. The levels of postoperative serum iPTH, calcemia, and phosphorus were lower than those at the preoperative level, the differences were statistically significant (P<0.050). The postoperative hypocalcemia was frequently seen in 38/50 (76.0%) patients, and it was effectively controlled by the intravenous calcium. After the follow-up for 3 months, the SHPT recurred in 5 cases (10.0%), of whom 3 cases underwent the TPTX+AT. The relapse rate in 12 months after the operation was 9.1% (2/22). There were no statistical differences among the three PTXs methods in the operation successful rate (χ2=3.351, P=0.211) and relapse rates in 3 months (χ2=1.321, P=0.753) and 12 months (χ2=1.794, P=0.411) after the operation.ConclusionsIn China, TPTX+AT is more common than SPTX and TPTX in clinical application. Operations of SPTX, TPTX, and TPTX+AT are safe and effective therapeutic methods for uremic SHPT, which can significantly improve biochemical indicators and quality of life of patients.
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.

ObjectiveTo investigate the significance of 99Tcm-MIBI SPECT dual-phase imaging, B-ultrasound and CT in the diagnosis of primary hyperparathyroidism, and its relationship with the level of serum calcium (CA). MethodsThe clinical data of 73 patients with parathyroid dysfunction (serum parathyroid hormone (PTH) > 130 pg/mL) were retrospectively analyzed. The 99Tcm-MIBI SPECT double phase imaging were performed in 73 cases, 63 cases underwent cervical B-ultrasound examination, and 16 cases underwent CT examination. According to the serum calcium (CA) levels, the patients were divided into CA < 2.7 mmol/L group and CA > 2.7 mmol/L group, and the postoperative pathological examination and followed-up results were as the standard, the sensitivity, specificity, positive predictive value, and negative predictive value of 99Tcm-MIBI SPECT dual-phase imaging, B-ultrasound and CT for diagnosis of PHPT in different serum CA levels were compared. ResultsThe sensitivity of 99Tcm-MIBI SPECT dual-phase imaging, B-ultrasound and CT examination for diagnosis of PHPT was 87.6%, 81.8% and 35.7%, respectively; the specificity was 87.5%, 75.5% and 50.0%, respectively; the positive predictive value was 98.2%, 93.7% and 83.3%, respectively; and the negative predictive value was 46.7%, 33.3% and 10%, respectively. The sensitivity, specificity, positive predictive value and negative predictive value of 99Tcm-MIBI SPECT dual-phase imaging and B-ultrasound examination for diagnosis of PHPT were significantly higher than those of CT examination(P < 0.05). The sensitivity, specificity, positive predictive value and negative predictive value of 99Tcm-MIBI SPECT dual-phase imaging for diagnosis of PHPT were higher than those of B-ultrasound examination, but the difference was not statistically significant (P > 0.05). In the CA < 2.7 mmol/L group, the sensitivity of 99Tcm-MIBI SPECT dual-phase imaging, B-ultrasound and CT examination for diagnosis of PHPT was 91.1%, 84.7% and 37.9%, respectively; the specificity was 80.2%, 72.9% and 49.7%, respectively; the positive predictive value was 96.8%, 96.0% and 79.4%, respectively; and the negative predictive value was 50.0%, 37.5% and 10.0%. In the CA > 2.7 mmol/L group, The sensitivity of 99Tcm-MIBI SPECT dual-phase imaging, B-ultrasound and CT examination for diagnosis of PHPT was 87.9%, 83.9% and 42.8%, respectively; the specificity was 83.3%, 79.2% and 50.0%, respectively; the positive predictive value was 96.9%, 94.1% and 75.0%, respectively; and the negative predictive value was 50.0%, 40.5% and 20.0%. There were no significant difference in the diagnostic accuracy between the 3 methods and the level of serum CV in different levels. ConclusionsThe diagnostic accuracy of 99Tcm-MIBI SPECT dual-phase imaging and B-ultrasound examination for diagnosis of PHPT patients with PTH > 130 pg/mL (especially parathyroid adenoma) were higher than that of CT examination, and it is not associated with the serum CA concentration.
ObjectiveTo analyze the factors influencing the hungry bone syndrome (HBS) in patients with secondary hyperparathyroidism (SHPT) after parathyroidectomy. MethodsThe clinical data of patients who underwent parathyroidectomy for SHPT in the 900th Hospital of the Joint Logistics Support Force from January 2016 to May 2021 were retrospectively analyzed. The risk factors for HBS were analyzed by binary logistic regression analysis. The cut-off value of risk factors for predicting postoperative HBS was analyzed by using recieve operating characteristic (ROC) curve. ResultsA total of 89 patients were included in this study, including 44 males and 45 females, with (47±11) years old. There were 42 (47.2%) patients with HBS. Compared with the patients without HBS, the patients with HBS was younger and had higher levels of preoperative parathyroid hormone, potassium, and alkaline phosphatase (ALP), the differences were statistically different (P<0.05). The multivariate binary logistic regression analysis showed that the higher preoperative ALP level was a risk factor for the HBS [OR (95%CI) = 1.014 (1.007, 1.020), P<0.001]. The area under the ROC curve (95%CI) of the preoperative ALP level in distinguishing the patients with HBS from without HBS was 0.957 (0.919, 0.996), and the optimal cut-off value of ALP for predicting postoperative HBS was 278.90 U/L. ConclusionsFrom the preliminary results of this study, it can be concluded that bone conversion status can be differentiated according to preoperative ALP level in patients with SHPT. When preoperative ALP level is higher than cut-off value, it is recommended that calcium supplementation should be given as soon as possible and blood calcium level should be closely monitored.
Objective To explore the application value of intraoperative gamma detector in patients with chronic kidney disease secondary hyperparathyroidism (sHPT) undergoing total parathyroidectomy (tPTX)+auto transplantation (AT). Methods A retrospective analysis of the clinical data of 110 sHPT patients who received tPTX+AT at Northern Jiangsu Province People’s Hospital from July 2014 to June 2019 was performed. Among them, 80 patients underwent tPTX+AT guided by the gamma detector during the operation (observation group), 30 patients underwent tPTX+AT under routine exploration (control group). We compared the operation time, number of parathyroid glands removed, serum intact parathyroid hormone (iPTH) concentration, serum calcium and phosphorus levels, as well as the occurrence of postoperative complications and recurrence rate were compared between the two groups. Results The number of parathyroid glands removed of the control group was lower than that of the observation group [(3.87±0.35) per case vs. (4.01±0.11) per case, P<0.05], but the operation time of the control group was longer [(115±25) min vs. (75±27) min, P<0.05]. Postoperative iPTH, serum calcium and serum phosphorus levels were significantly reduced in all patients. After the operation, the symptoms of pruritus, bone pain, and muscle weakness were relieved or disappeared. There was no death, dysphagia, drinking water choking cough, and superior laryngeal nerve injury occurred. One patient in the observation group and one patient in the control group had hoarseness, and one patient in the control group had cervical incision bleeding; one patient in the observation group and four patients in the control group suffered short-term postoperative recurrence due to incomplete parathyroidectomy. There was no significant difference in the incidence of complications (χ2=2.413, P>0.05), but the short-term postoperative recurrence rate of the observation group was lower than that of the control group (χ2=7.342, P<0.05). Conclusion Gamma detector is helpful for rapid identification of typical hyperplasia and ectopic parathyroid glands during operation, and can improve the accuracy of tPTX , save operation time, and reduce the recurrence.
ObjectiveTo investigate the role of multiple disciplinary team (MDT) during surgical treatment of renal secondary hyperparathyroidism (SHPT), and identify management points of Departments of Nephrology and Endocrinology.MethodsThe data of patients with chronic kidney disease undergoing surgical treatment for SHPT in West China Hospital of Sichuan University between January 2009 and December 2018 were retrospectively collected. We explained the surgical treatment of MDT in the management of renal SHPT, and compared the changes before and after the establishment of MDT.ResultsA total of 187 patients including 101 males and 86 females were enrolled, with an average age of (47.60±11.28) years old and median dialysis vintage of 7 years. Under MDT, the number of patients with parathyroidectomy increased [(8.50±5.10) vs. (59.50±2.12) patients/year, P<0.001] and the completion rate of preoperative examinations were greatly improved (P<0.001). The success rate of surgery was also increased (86.8% vs. 97.5%, P=0.010). Proportion of patients who were admitted to the Department of Nephrology was significantly increased (39.7% vs. 84.9%, P<0.001). Most patients after surgery were transferred to the Department of Endocrinology (5.9% vs. 77.3%, P<0.001) to manage postoperative complications and metabolic bone disease, and thus normalized the management of SHPT.ConclusionsThe MDT contributes to management of renal SHPT, which is worthy of popularization and spreading. The management of internal medicine departments during surgical treatment of SHPT based on MDT is important, because they can be helpful to complete preoperative examinations and preoperative preparation as well as to alleviate postoperative complications.
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.
