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 summarize the current treatment status of uremic secondary hyperparathyroidism (SHPT) in order to improve the understanding of uremic SHPT and to guide clinical work.MethodThe relevant literatures at home and abroad on surgical treatment of uremic SHPT were readed and reviewed.ResultsFor intractable SHPT patients with ineffective medical treatment, surgical treatment was still irreplaceable, which could significantly improve biochemical indicators and quality of life of SHPT patients. However, there was no unified standard for surgical indications and the choice of different operation methods. In addition, there was a certain controversy about whether there was a need for preoperative parathyroidectomy in patients with SHPT who were willing to have a kidney transplant.ConclusionAlthough there are still some problems need to be solved in surgical treatment of SHPT, however, it’s widely recognized and used by clinicians, which can improve the symptoms of SHPT patients and bring bettersurvival benefits.
ObjectiveTo explore the selection and application value of preoperative stereotactic localization in the surgical treatment of secondary hyperparathyroidism.MethodsThe preoperative ultrasound, CT, and methoxyisobutylisonitrile (MIBI) scan data of 54 patients with secondary hyperparathyroidism confirmed by pathological examination in the Department of General Surgery of the 900th Hospital of the Joint Logistics Team from September 2016 to January 2020 were retrospectively analyzed, to explore the localization accuracy of the three methods alone or in combination.ResultsIn this study, a total of 207 parathyroids were detected, 1 was misdiagnosed (ectopic thymus),9 were missed, and 216 parathyroids were removed. The preoperative localization accuracy of CT, ultrasound, and MIBI was the highest (95.39%, 207/217), followed by ultrasound and MIBI (93.55%, 203/217) and CT+MIBI (89.40%, 194/217), compared with other single or two methods, the differences were statistically significant (P<0.05). The accuracy of CT combined with ultrasound localization (82.49%, 179/217) was slightly higher than that of MIBI scan alone (78.80%, 171/217), but the difference was not statistically significant (P=0.060). Although the location accuracy of MIBI scan was slightly higher than that of ultrasound localization (77.88%, 169/217), the difference was not statistically significant (P=0.084).ConclusionIn order to maximize the accuracy of preoperative stereotactic localization of secondary hyperparathyroidism, ultrasound, CT, and MIBI should be combined.
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.
To standardize the treatment of secondary hyperparathyroidism and effectively meet the needs of practical clinical work, we gathered experts and nursing experts from Departments of Thyroid Surgery, Nephrology, Endocrinology and Metabolism, Nuclear Medicine, Ultrasound, Anesthesiology, Cardiology, and other departments at West China Hospital of Sichuan University to solicit opinions. This consensus was finally established based on published guidelines and the best evidence in Chinese and English combined with clinical practice. This consensus is intended to summarize and conclude, to the greatest extent possible, the practical issues encountered in diagnosing and treating secondary hyperparathyroidism in perioperative settings and to provide recommendations for clinical practice.
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.
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.
