Abstract
BACKGROUND Patients with renal hyperparathyroidism undergoing parathyroidectomy may experience relapse. Reoperation for persistent or recurrent disease, particularly in the neck region, is challenging and has a high complication rate because of difficult exploration. We aimed to evaluate the effectiveness of neck reoperation in renal hyperparathyroidism. METHODS Patients with recurrent or persistent renal hyperparathyroidism who underwent neck reoperation between January 2015 and August 2022 were investigated, focusing on operative findings, perioperative biochemical changes, and significance of intraoperative parathyroid hormone (PTH) measurements. RESULTS During reoperation, 35 parathyroid glands were identified and removed from the 26 enrolled patients, with one, two, and three glands retrieved from 19 (73.2%), five (19.2%), and two (7.6%) patients, respectively. Most removed glands (68.6%) were located in the lower neck, followed by the mediastinum, carotid sheath, and upper neck. Successful resection, defined as a postoperative PTH level of <300 pg/mL, was achieved in 21 patients (80.8%). The remaining four (15.4%) and one (3.9%) patients were classified as having persistent and recurrent disease, respectively. The extent of PTH reduction was correlated with specimen weight, specimen volume, and preoperative alkaline phosphatase (ALP) level. The mean intraoperative PTH ratio (10 min after excision/pre-excision) was 0.23, and all patients with persistent or recurrent disease had a PTH ratio >0.3. Severe hypocalcemia (<7.5 mg/dL) occurred in 19 (73.0%) patients after reoperation. CONCLUSIONS Neck reoperation is an effective therapeutic option in patients with recurrent or persistent renal hyperparathyroidism. A decrease in PTH level by >70% during reoperation (PTH ratio <0.3) predicts successful resection.

Abstract
Objective:To evaluate the clinical effect of reoperation in persistent hyperparathyroidism (PHPT) patients after operation of parathyroidectomy combined with autotransplantation(PTX+AT) on secondary hyperparathyroidism (SHPT) . Methods:18 PHPT patients who treated with reoperation after PTX+AT were enrolled in this study during the period from Aug 2012 to Dec 2021 in the Department of Otolaryngology Head and Neck Surgery of Peking University Civil Aviation School of Clinical Medicine, Civil Aviation General Hospital. The remaining parathyroid glands were located by preoperative colour Doppler ultrasonography, radionuclide imaging, enhanced CT and MR imaging in the neck region . Based on the imaging findings, the remaining parathyroid glands were removed in situ, and the missed ectopic or extra parathyroid glands were resected with an extended surgical scope according to the parathyroid dissection method. The surgical effect was evaluated by the changes of clinical symptoms, the dynamic change of serum intact paramyroidhomone(i-PTH) between preoperative and postoperative periods and the surgical complications. Results:All the 18 patients accepted successful operation. 30 parathyroid glands were resected confirmed by postoperative pathology, including 16 in situ and 14 ectopic glands(5 in superior mediastinum, 4 in thymus, 2 in posterior mediastinum ,2 in thyroid glands, 1 in carotid sheath).Osteoarthropathy and skin itching were significantly relieved or even disappeared at 6 h after surgery. The levels of serum i-PTH, calcium and phosphorus reached the standards and muscle weakness was significantly improved 1 week after surgery. 16 patients presented hypocalcemia and returned to normal after supplement of calcium. Hoarseness due to temporary injury of laryngeal nerve was found in 6 cases. No serious complications or death occurred after the operation.There was no recurrence after 1 year follow-up. Conclusion:Reoperation is the first choice for SHPT patients complicated with persistent hyperparathyroidism. Multiple imaging examinations are used to locate the residual parathyroid, especially the ectopic gland. Expanded surgical scope is applied to resect all the residual parathyroid glands(ectopic, in situ and concealed parathyroid) according to the concept of dissection parathyroidectomy. The surgery is effective and safe. Patients'quality of life and long-term survival rate is improved.

Abstract
OBJECTIVE To develop evidence-based recommendations for safe, effective, and appropriate treatment of secondary (SHPT) and tertiary (THPT) renal hyperparathyroidism. BACKGROUND Hyperparathyroidism is common among patients with chronic kidney disease, end-stage kidney disease, and kidney transplant. The surgical management of SHPT and THPT is nuanced and requires a multidisciplinary approach. There are currently no clinical practice guidelines that address the surgical treatment of SHPT and THPT. METHODS Medical literature was reviewed from January 1, 1985 to present January 1, 2021 by a panel of 10 experts in SHPT and THPT. Recommendations using the best available evidence was constructed. The American College of Physicians grading system was used to determine levels of evidence. Recommendations were discussed to consensus. The American Association of Endocrine Surgeons membership reviewed and commented on preliminary drafts of the content. RESULTS These clinical guidelines present the epidemiology and pathophysiology of SHPT and THPT and provide recommendations for work-up and management of SHPT and THPT for all involved clinicians. It outlines the preoperative, intraoperative, and postoperative management of SHPT and THPT, as well as related definitions, operative techniques, morbidity, and outcomes. Specific topics include Pathogenesis and Epidemiology, Initial Evaluation, Imaging, Preoperative and Perioperative Care, Surgical Planning and Parathyroidectomy, Adjuncts and Approaches, Outcomes, and Reoperation. CONCLUSIONS Evidence-based guidelines were created to assist clinicians in the optimal management of secondary and tertiary renal hyperparathyroidism.

Abstract
PURPOSE Hyperparathyroidism (HPT) is a common disorder. A cure can only be achieved by removing all diseased glands. It is critical to localize the hyperfunctioning glands exactly to prevent extensive surgical exploration. The number of false negative/inconclusive results in standard imaging techniques is high. We aimed to evaluate the diagnostic accuracy of 18F-Fluorocholine-PET in combination with contrast-enhanced CT (FCH-PET/CT) and its sensitivity in patients with primary, secondary/tertiary, and familial HPT with negative and/or discordant findings in ultrasound and/or 99mTc-sestamibi scintigraphy/SPECT/CT. METHODS A total of 96 patients with HPT and negative/equivocal conventional imaging were referred for FCH-PET/CT. In this retrospective, single institution study, 69 patients, who have undergone surgery and histopathologic workup, were analyzed. Of the 69 patients included, 60 patients suffered from primary HPT, four from secondary or tertiary HPT, and five from familial HPT. Sensitivities, positive predictive values, and accuracies were calculated. RESULTS Sensitivity/positive predictive value (PPV) per lesion was 87.5/98.3% for primary HPT, 75/100% for secondary/tertiary HPT and 25/66.7% for familial HPT. Sensitivity/PPV per patient was 91.5/98.2% for primary HPT, 100/100% for secondary/tertiary HPT and 50/100% for familial HPT. All patients showed normalized serum calcium levels in the postoperative period. The follow-up rate was 97%. Of the patients included in the study, 58 of 60 patients with primary HPT, and four of four patients with secondary/tertiary HPT showed normal calcium and parathyroid hormone (PTH) levels after six months and were cured. Of the patients with familial HPT, four of five patients were cured. CONCLUSION Diagnostic accuracy of 18F-Fluorocholine-PET/CT for patients with pHPT is excellent. 18F-Fluorocholine-PET/CT is a valuable tool for endocrine surgeons to optimize the surgical treatment of patients with hyperparathyroidism.

A case of a hemodialysis patient with secondary hyperparathyroidism who was resistant to etelcalcetide treatment but not to cinacalcet hydrochloride. CEN Case Rep 2021; 11:254-258. [PMID: 34787825 PMCID: PMC9061916 DOI: 10.1007/s13730-021-00664-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Accepted: 11/10/2021] [Indexed: 11/28/2022] Open
Abstract
Although both cinacalcet and etelcalcetide are calcimimetics that directly inhibit parathyroid hormone (PTH) secretion by activating the calcium (Ca)-sensing receptor (CaSR), their binding sites are different. We report a first case of a hemodialysis (HD) patient with secondary hyperparathyroidism (SHPT), in whom cinacalcet, but not etelcalcetide, could reduce serum intact PTH (i-PTH) levels. A HD patient received total parathyroidectomy (PTx) with auto-transplantation 16 years earlier. Due to SHPT relapse, cinacalcet was started at 7 years after PTx. His i-PTH levels had been controlled with both 75–100 mg of cinacalcet and 4.5 μg/week of calcitriol for a year before switching from cinacalcet to etelcalcetide. At 1 month following the switch, his serum i-PTH level increased to 716 pg/mL. The dose of etelcalcetide was gradually increased and finally reached the maximal dose of 45 mg/week. Because even the maximal dose of etelcalcetide for > 4 months did not reduce his serum i-PTH levels to < 700 pg/mL, etelcalcetide was switched to 50 mg/day of cinacalcet, which reduced the levels to 208 pg/mL at 2 months after the switch. Genomic sequencing test using whole blood revealed no mutation in the portion including Cys 482 of CaSR gene. The patient was resistant to etelcalcetide treatment but not to cinacalcet, suggesting the possibility that the enlarged parathyroid gland has some change in the portion including Cys 482 in the CaSR gene. Therefore, considering the possibility of etelcalcetide resistance during SHPT treatment should be kept in mind.

Abstract
Objectives The curative treatment of primary hyperparathyroidism (PHPT) is surgery. Persistent and recurrent disease may develop after surgical treatment. In this study, we aimed to evaluate the surgical cure rate in patients who underwent surgery for PHPT in our clinic. Methods The data of patients who underwent parathyroidectomy for PHPT by two experienced surgeons between 2000 and 2015 in our clinic were retrospectively evaluated. Patients who were followed for at least 6 months after their first parathyroidectomy were included in the study. Surgical cure and persistent and recurrent disease rates were evaluated in patients. Results During this period, 368 interventions were performed in 357 patients (293 F and 64 M) who were operated for PHPT in our clinic, with a mean age of 54.9±13.1 years. In the first surgery, 116 patients (32.5%) had bilateral neck exploration, 251 patients (67.5%) had unilateral neck exploration (UNE) or focused parathyroid surgery (FPS). In the first operation, 343 patients (96.1%) had cure, 14 patients (13 F and 1 M) remained persistent. Secondary surgical intervention was performed in 11 patients. UNE or FPS was performed to 10 patients (90.9%); partial sternotomy was performed to one patient. Ten of the patients had cure. Three of these patients had a solitary parathyroid adenoma that was not removed in the first surgery, and seven patients had a second adenoma. Four patients remained persistent (1.1%). Recurrent disease developed in four patients during follow-up (1.1%). Total cure rate was 97.8%. Conclusion The only definitive treatment for PHPT is surgery. High surgical cure can be achieved by pre-operative evaluation and appropriate surgical planning. However, persistent PHPT may develop, especially due to double adenoma or ectopic location. Patients with persistent PHPT can be evaluated with repeat imaging methods and with appropriate surgical planning, a high cure rate can be obtained in secondary surgery, which can increase the total surgical cure rate. Recurrence rate is rare.

Abstract
Background Forearm autotransplantation after parathyroidectomy has turned into the standard method for secondary hyperparathyroidism (SHPT) treatment in chronic kidney disease patients. Our study aimed to explore the effects of three methods including muscle, subcutaneous and muscle + subcutaneous transplant methods on SHPT. Methods Seventy five SHPT patients were enrolled and assigned into the muscle + subcutaneous (M + S) (n = 26), muscle (M) (n = 35), and subcutaneous (S) (n = 14) groups. The operation efficacy evaluation included preoperative and postoperative biological characteristics such as parathyroid hormone (PTH), serum phosphorus, serum calcium and alkaline phosphatase (ALP). The data were recorded from pre-operation time point to 1, 2, 3, 6, 12, 18, 24 month (mo) postoperation periods. After operation, short-form health survey (SF-36) scores was made for life quality identification at 1, 2, 3, 6, 12, 24 time points. Symptoms about SHPT including bone pain, fracture, pruritus, and coronary artery calcification were followed-up based on the scale. Results Compared with the preoperative record, all the M + S, M, and S groups showed postoperative decreased levels of PTH, serum phosphorus, serum calcium, calcium-phosphorus. In M + S group, the PTH and serum calcium level kept more steady compared with the M and S groups during a 24 mo duration observation. After this, a SF-36 score scale which represents the life quality show M + S group got more scores at 3, 6, 12, 18 and 24 mo points. At last, the incidence of SHPT associated symptoms including Bone pain, Fracture, Pruritus, and Coronary artery calcification in M + S group were decreased compared with M and S groups at 1, 3, 6, 12 and 24 mo post-operation time points. Conclusion M + S seems to be an efficient method for medical treatment of SHPT patients in the control of PTH and serum calcium. This mixed transplant strategy improves the biochemical characterizes compared with M and S groups in SHPT patients. Furthermore, the M + S method make beneficial on clinical outcomes and life quality of patients.

Intact parathyroid hormone levels localize causative glands in persistent or recurrent renal hyperparathyroidism: A retrospective cohort study. PLoS One 2021; 16:e0248366. [PMID: 33793603 PMCID: PMC8016254 DOI: 10.1371/journal.pone.0248366] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2020] [Accepted: 02/24/2021] [Indexed: 11/19/2022] Open
Abstract
Persistent or recurrent renal hyperparathyroidism may occur after total parathyroidectomy and transcervical thymectomy with forearm autograft under continuous stimulation due to uremia. Parathyroid hormone (PTH) levels may reflect persistent or recurrent renal hyperparathyroidism because of the enlarged autografted parathyroid glands in the forearm or remnant parathyroid glands in the neck or mediastinum. Detailed imaging requires predictive localization of causative parathyroid glands. Casanova and simplified Casanova tests may be convenient. However, these methods require avascularization of the autografted forearm for >10 min with a tourniquet or Esmarch. The heavy pressure during avascularization can be incredibly painful and result in nerve damage. An easier method that minimizes the burden on patients in addition to predicting the localization of causative parathyroid glands was developed in this study. Ninety patients who underwent successful re-parathyroidectomy for persistent or recurrent renal hyperparathyroidism after parathyroidectomy between January 2000 and July 2019 were classified according to the localization of causative parathyroid glands (63 and 27 patients in the autografted forearm and the neck or mediastinum groups, respectively). Preoperatively, intact PTH levels were measured from bilateral forearm blood samples following a 5-min avascularization of the autografted forearm. Cutoff values of the intact PTH ratio (intact PTH level obtained from the non-autografted forearm before re-parathyroidectomy/intact PTH level obtained from the autografted forearm before re-parathyroidectomy) were investigated with receiver operating characteristic curves to localize the causative parathyroid glands. Intact PTH ratios of <0.310 with an area under the curve (AUC) of 0.913 (95% confidence interval [CI]: 0.856–0.970; P < 0.001) and >0.859 with an AUC 0.744 (95% CI: 0.587–0.901; P = 0.013) could predict causative parathyroid glands in the autografted forearm and the neck or mediastinum with diagnostic accuracies of 81.1% and 83.3%, respectively. Therefore, we propose that the intact PTH ratio is useful for predicting the localization of causative parathyroid glands for re-parathyroidectomy.

Abstract
Secondary hyperparathyroidism (SHPT) affects a majority of patients with chronic kidney disease (CKD) of stage 3 or worse. Despite the development of calcimimetics and their effectiveness in treating SHPT, many patients continue to fail medical management and should be referred to a parathyroid surgeon. In this narrative review, we summarize the indications for surgical referral, preoperative planning, intraoperative strategies to guide resection, and postoperative management. In the absence of universal guidelines, it can be difficult to determine when it is appropriate to make this referral. The majority of studies evaluating parathyroidectomy (PTX) for SHPT use the criteria of parathyroid hormone level (PTH) >800 pg/ml with hypercalcemia and/or hyperphosphatemia, which may be accompanied by symptoms such as bone pain and pruritis that can improve after surgery. Although the reported utility of the various imaging modalities (i.e., 99m-technetium-sestamibi scintigraphy with computed tomography [SPECT/CT], CT, or ultrasound) is highly variable in SHPT, SPECT/CT appears to be the most sensitive. Intraoperatively, PTH monitoring is effective in predicting long-term cure of SHPT but not in predicting hypoparathyroidism. Ectopic and supernumerary parathyroid glands are common in these patients and are often implicated in persistent or recurrent disease. Postoperatively, patients are at risk of severe hypocalcemia and hungry bone syndrome requiring close monitoring and replenishment.

Application of Tissue Aspirate Parathyroid Hormone Assay for Imaging Suspicious Neck Lesions in Patients with Complicated Recurrent or Persistent Renal Hyperparathyroidism. J Clin Med 2021; 10:jcm10020329. [PMID: 33477403 PMCID: PMC7830567 DOI: 10.3390/jcm10020329] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Revised: 01/12/2021] [Accepted: 01/14/2021] [Indexed: 11/17/2022] Open
Abstract
Background: Comprehensive pre-reoperative localization is essential in complicated persistent or recurrent renal hyperparathyroidism. The widely used imaging studies sometimes lead to ambiguous results. Our study aimed to clarify the role of tissue aspirate parathyroid hormone (PTH) assay with a new positive assay definition for imaging suspicious neck lesions in these challenging scenarios. Methods: All patients with complicated recurrent or persistent renal hyperparathyroidism underwent parathyroid sonography and scintigraphy. Echo-guided tissue aspirate PTH assay was performed in suspicious lesions revealed by localization imaging studies. The tissue aspirate PTH level was determined by an immunoradiometric assay. We proposed a newly-developed definition for positive assay as a washout level higher than one-thirtieth of the serum PTH level obtained at the same time. The final diagnosis after re-operation was confirmed by the pathologists. Results: In total, 50 tissue aspirate PTH assays were performed in 32 patients with imaging suspicious neck lesions, including discrepant results between scintigraphy and sonography in 47 lesions (94%), unusual locations in 19 lesions (38%), multiple foci in 28 lesions (56%), and locations over previously explored areas in 31 lesions (62%). Among 39 assay-positive lesions, 13 lesions (33.3%) were not identified by parathyroid scintigraphy, and 28 lesions (71.8%) had uncertain parathyroid sonography findings. The final pathology in patients who underwent re-operative surgery proved the tissue aspirate PTH assays had a 100% positive predictive value. Conclusions: Our findings suggest tissue aspirate PTH assay with this new positive assay definition is beneficial to clarify the nature of imaging suspicious lesions in patients with complicated persistent or recurrent renal hyperparathyroidism.

Abstract
BACKGROUND Chronic kidney disease-mineral and bone disorder (CKD-MBD) has more influence in the elderly. Parathyroidectomy remains the golden standard for this situation but has tended to be excluded for older patients for many reasons. This study aimed to evaluate the efficacy and safety of the surgery in the elderly population. METHODS 156 patients were included and arranged into younger (≦65 years of age, n = 139) and elderly (>65 years of age, n = 17) groups. The change of bone mineral density (BMD) data, recovery potential {[(postoperative BMD) - (preoperative BMD)]/(preoperative BMD) ∗ 100%}, surgical successful rate and related complications were collected. RESULTS Both groups exhibited significant postoperative improvement on the BMD results. The recovery potential of the elderly was not lower than the younger group. High success rate and none of persistent vocal palsy, hypocalcemia or any sequela were also observed in the elderly. CONCLUSIONS Parathyroidectomy is an effective and safe intervention for the CKD-MBD in the elderly.

Abstract
BACKGROUND Secondary hyperparathyroidism is a common acquired disorder seen in chronic renal failure. Its pathophysiology is mainly due to hyperphosphatemia and vitamin D deficiency and resistance. When medical treatment fails, subtotal and total parathyroidectomy with autotransplantation are the standard procedures, although both are associated with high recurrence rates. METHODS AND RESULTS 4 patients experienced persistence and 9 relapse. The first 4 were subjected to reoperation after 6 months for the persistence of symptoms due to the finding of a supernumerary adenomatous gland while the remaining patients at the reoperation showed in 5 cases 2 more glands in over thymic position, and 4 an hyperplasia of the residual glandular tissue. A classic cervicotomy was sufficient to remove the residual parathyroid in patients with persistent hyperparathyroidism. For cases of recurrent hyperparathyroidism it was enough a medial approach and sometimes lateral for the complete excision of the hyperplastic tissue. The advent of the intraoperative technique of parathyroid hormone dosage allowed a better performance of the surgical technique for the last 3 patients undergoing reoperation. After reoperation all patients had immediate regression of clinical symptoms with normalization of serum calcium and PTH levels. CONCLUSIONS On the basis of these considerations, diagnostic imaging has a not negligible role because during the first intervention helps to have an idea of the possible location of the glands and thus to avoid the risk of recurrence and relapse due to ectopic or supernumerary tissue.

Abstract
A 19-year-old patient presented with slowly enlarging, painless, left-sided cervical mass. She had a background of multiple endocrine neoplasia 2B and had undergone a total thyroidectomy for medullary thyroid carcinoma during childhood. A cervical recurrence was therefore suspected. Ultrasonographic and MRI examination revealed a well-defined lesion within the left sternocleidomastoid muscle. Further evaluation with sestamibi and single-photon emission CT revealed elevated tracer uptake within the lesion. Cytological analysis, following ultrasound-guided sampling, revealed absent staining for calcitonin and blood samples confirmed a normal serum calcitonin level; however, the serum parathyroid hormone level was elevated. Overall, summative findings were consistent with a diagnosis of a parathyroid adenoma arising within the left sternocleidomastoid muscle. Given that this is not a location for a physiological parathyroid tissue, the adenoma might have arisen within the autotransplanted parathyroid tissue, injected into the muscular sheath during thyroidectomy. The clinical, radiological and pathological features are considered in this article.

Abstract
Aim The aim of this study was to evaluate the outcomes of surgery for patients with secondary renal hyperparathyroidism (rHPT). Methods This is a retrospective cohort study. Our institutional database was searched for eligible patients treated in 1995–2014. The inclusion criterion was initial parathyroidectomy for rHPT. Clinical and follow-up data were analyzed to estimate the cure rate (primary outcome), and morbidity (secondary outcome). Results The study group comprised 297 patients (154 females, age 44.5 ± 13.7 years, follow-up 24.6 ± 10.5 months), including 268 (90.2 %) patients who had underwent subtotal parathyroidectomy, and 29 (9.8 %) who had had incomplete parathyroidectomy. Intraoperative iPTH assay was utilized in 207 (69.7 %) explorations. Persistent rHPT occurred in 12/268 (4.5 %) patients after subtotal parathyroidectomy and 5/29 (17.2 %) subjects after incomplete parathyroidectomy (p = 0.005). The patients operated on with intraoperative iPTH assay had a higher cure rate than non-monitored individuals, 201/207 (97.1 %) vs. 79/90 (87.8 %), respectively (p = 0.001). In-hospital mortality occurred in 1/297 (0.3 %) patient. The hungry bone syndrome occurred in 84/268 (31.3 %) patients after subtotal parathyroidectomy and 2/29 (6.9 %) subjects after incomplete parathyroidectomy (p = 0.006). Transient recurrent laryngeal nerve paresis occurred in 14/594 (2.4 %) and permanent in 5/594 (0.8 %) nerves at risk. Conclusions Subtotal parathyroidectomy is a safe and efficacious treatment for patients with rHPT. Utilization of intraoperative iPTH assay can guide surgical exploration and improve the cure rate.

Abstract
OBJECTIVE The usefulness, the methods and the criteria of intra-operative monitoring of the parathyroid hormone (ioPTH) during parathyroidectomy (PTX) for renal secondary hyperparathyroidism (rSHPT) in patients on chronic hemodialysis remain still matter of debate. The present study aimed to evaluate the ability of a low cost central-laboratory second generation PTH assay to predict an incomplete resection of parathyroid glands (PTG). METHODS The ioPTH decay was determined In 42 consecutive patients undergoing PTX (15 subtotal and 27 total without auto-transplant of PTG) for rSHPT. The ioPTH monitoring included five samples: pre-intubation, post-manipulation of PTG and at 10, 20 and 30min post-PTG excision. The patients with PTH exceeding the normal value (65pg/ml) at the first postoperative week, 6 and 12months were classified as persistent rSHPT. RESULTS The concentrations of ioPTH declined significantly over time in patients who received total or subtotal PTX; however, no difference was found between the two types of PTX. Irrespective of the type of PTX and the number of PTG removed, combining the absolute and percentage of ioPTH decay at 30min after PTG excision, we found high sensitivity (100%), specificity (92%), negative predictive value (100%) and accuracy (93%) in predicting the persistence of rSHPT. CONCLUSIONS The monitoring of the ioPTH decline by a low cost central-laboratory second generation assay is extremely accurate in predicting the persistence of disease in patients on maintenance hemodialysis undergoing surgery for rSHPT.

Abstract
AIMS Our aim was to evaluate the long-term effect of cinacalcet in patients with hypercalcaemic secondary hyperparathyroidism (SHPT) after renal transplantation (RT) in order to expand real-world data in this population. METHODS We performed a multicentre, observational, retrospective study in 17 renal transplant units from Spain. We collected data from renal recipients with hypercalcaemic (calcium >10.2 mg/dL) SHPT (intact parathyroid hormone (iPTH) > 120 pg/mL) who initiated cinacalcet in the clinical practice. RESULTS We included 193 patients with a mean (standard deviation (SD)) age of 52 (12) years, 58% men. Cinacalcet treatment was initiated at a median of 20 months after RT (median dose 30 mg/day). Mean calcium levels decreased from a mean (SD) of 11.1 (0.6) at baseline to 10.1 (0.8) at 6 months (9.0% reduction, P < 0.0001). Median iPTH was reduced by 23.0% at 6 months (P = 0.0005) and mean phosphorus levels increased by 11.1% (P < 0.0001). The effects were maintained up to 3-years. No changes were observed in renal function or anticalcineurin drug levels. Only 4.1% of patients discontinued cinacalcet due to intolerance and 1.0% due to lack of efficacy. CONCLUSIONS In renal transplant patients with hypercalcaemic SHPT, cinacalcet controlled serum calcium, iPTH and phosphorus levels up to 3 years. Tolerability was good.

Abstract
OBJECTIVE Parathyroid scintigraphy using (99m)Tc-MIBI is not currently considered a valuable diagnostic tool for the localization of involved glands in patients with secondary hyperparathyroidism (SHPT). However, published data about its diagnostic accuracy are discordant and a meta-analysis about this topic is still lacking. The aim of our study is to meta-analyze the published data about the diagnostic performance of (99m)Tc-MIBI parathyroid scintigraphy in patients with SHPT. METHODS A comprehensive computer literature search of studies published in PubMed/MEDLINE, Scopus and Embase databases through September 2011 and regarding the diagnostic accuracy of (99m)Tc-MIBI parathyroid scintigraphy in patients with SHPT was carried out. Only articles in English language in which at least 10 patients with SHPT underwent planar (99m)Tc-MIBI parathyroid scintigraphy were selected. Pooled sensitivity, pooled specificity and area under the ROC curve on a per lesion-based analysis were calculated to measure the diagnostic accuracy of (99m)Tc-MIBI parathyroid scintigraphy in SHPT patients. RESULTS Twenty-four studies comprising 471 patients were included in this meta-analysis. The pooled sensitivity and specificity of (99m)Tc-MIBI parathyroid scintigraphy in detecting hyperplastic glands in SHPT patients were 58 % [95 % confidence interval (95 % CI) 52-65 %] and 93 % (95 % CI 85-100 %), respectively, on a per lesion-based analysis. Area under ROC curve was 0.75. CONCLUSIONS In patients with SHPT and diffuse or nodular hyperplasia, planar parathyroid scintigraphy using (99m)Tc-MIBI has demonstrated an inadequate diagnostic accuracy. Therefore, it should not be considered as a first-line diagnostic imaging method in the pre-surgical detection of hyperplastic parathyroid glands.

Abstract
The purposes of this study are to evaluate the merits of surgical treatment, including subtotal parathyroidectomy (SP) and total parathyroidectomy (TP), in patients with tertiary hyperparathyroidism (THPT) and compare the outcome of the two surgical options. Medical records of patients undergoing parathyroidectomy for THPT were retrospectively reviewed and long-term outcomes between the two groups were compared. Fourteen out of 488 renal transplantation recipients required parathyroidectomy for THPT during a 24-year follow-up period with a median follow-up of 35.5 [interquartile range (IQR), 19.3–133.3] months. All patients had hypercalcemia, whereas 13 had varying symptoms and one was asymptomatic. Median serum calcium level decreased from 12.4 (IQR, 11.9–12.6) mg/dL preoperatively to 8.9 (IQR, 8.1–9.4) mg/dL postoperatively ( P = 0.001), whereas median intact parathyroid hormone (iPTH) dropped from a preoperative level of 340.5 (IQR, 247–540) pg/mL to 55.1 (IQR, 24.4–66.4) pg/mL after surgery ( P = 0.018). Comparison between patients receiving TP and SP revealed no difference in incidence of recurrence or permanent complications, whereas the former had significantly lower calcium levels ( P = 0.048) and higher phosphorus levels ( P = 0.017) compared with the latter. Moreover, a significant reduction in calcium level was noted in TP group on long-term follow-up compared with their immediately postoperative level (8.1 vs 9.0 mg/dL, respectively, P < 0.05), whereas there was no significant decrease in SP group. We concluded that parathyroidectomy is efficient and safe in treating THPT. Because TP would increase the risk of hypocalcemia, a less radical procedure (SP) is preferred.

Abstract
We report a peculiar case of recurrent hyperparathyroidism caused by hyperplasia of a forearm graft implanted following a total parathyroidectomy in a 38-year-old patient with chronic renal failure. The forearm graft hyperplasia was detected using (99)Tc(m)-sestamibi scanning, which identified hyperplastic transplanted parathyroid tissue in the forearm of the patient. During the initial surgery, the surgeon failed to mark the parathyroid tissue with sutures or clips to facilitate locating it. Therefore, we referred the patient for radioguided surgery. This surgical procedure allowed us to locate and completely remove the hyperfunctioning transplanted parathyroid tissue.

Abstract
Secondary and tertiary hyperparathyroidism (HPT) develop in patients with renal failure due to a variety of mechanisms including increased phosphorus and fibroblast growth factor 23 (FGF23), and decreased calcium and 1,25-dihydroxy vitamin D levels. Patients present with various bone disorders, cardiovascular disease, and typical laboratory abnormalities. Medical treatment consists of controlling hyperphosphatemia, vitamin D/analog and calcium administration, and calcimimetic agents. Improved medical therapies have led to a decrease in the use of parathyroidectomy (PTX). The surgical indications include parathyroid hormone (PTH) levels >800 pg/ml associated with hypercalcemia and/or hyperphosphatemia despite medical therapy. Other indications include calciphylaxis, fractures, bone pain or pruritis. Transplant recipients often show decreased PTH, calcium and phosphorus levels, but some will have persistent HPT. Evidence suggests that PTX may cause deterioration in renal graft function in the short-term calling into the question the indications for PTX in these patients. Pre-operative imaging is only occasionally helpful except in re-operative PTX. Operative approaches include subtotal PTX, total PTX with or without autotransplantation, and possible thymectomy. Each approach has its proponents, advantages and disadvantages which are discussed. Intraoperative PTH monitoring has a high positive predictive value of cure but a poor negative predictive value and therefore is of limited utility. Hypocalcemia is the most common complication requiring aggressive calcium administration. Benefits of surgery may include improved survival, bone mineral density and alleviation of symptoms.

Abstract
Preoperative imaging studies have an important role in facilitating successful localization of adenomas for surgeons. Their use has increased and parallels the recent growth of minimally invasive parathyroidectomy. Based on findings that scintigraphy is reported to have the highest accuracy for localization of adenomas when compared with anatomic imaging techniques, this article discusses the current role and limitations of imaging, with a focus on scintigraphy, in the evaluation of patients before surgery for hyperparathyroidism.

Abstract
OBJECTIVES/BACKGROUND The aim of this study is to investigate the predictive value of intraoperative parathormone measurement addressing successful surgical resection in patients with secondary hyperparathyroidism. METHODS The study included 42 consecutive patients operated on between May 2006 and July 2008. Patients were grouped according to successful surgery (Group 1, n = 36) and persistent postoperative hyperparathyroidism (Group 2, n = 6). Serum phosphorus (P), total calcium (tCa), ionized calcium (iCa), intact parathormone (iPTH), and alkaline phosphatase (ALP) were drawn preoperatively and intraoperatively upon 15 minutes after completion of resection (iPTH(15)). The rate of decrease of pith detected by iPTH(15) compared to preoperative values was calculated (iPTH(%)). RESULTS Preoperative P, tCa, iCa, iPTH, and ALP were comparable. Subtotal parathyroidectomy (sPx) (n = 27) and total parathyroidectomy with autotransplantation (tPx) (n = 15) were performed. Mean iPTH(15) value, iPTH(%) rates were 145.9 +/- 12.3 pg/mL, % 91.6 +/- 0.7, and 522.5 +/- 85.4 pg/mL, % 75.1 +/- 2.0 (P = ,001) in Groups 1 and 2, respectively. Mean serum tCa and iCa at POD#1 in Group 1 were 7.6 +/- 0.1 mg/dL, 0.910 +/- 0.4 mmol/L, and Group 2 were 8.3 +/- 0.3 mg/dL, 1.050 +/- 0.4 mmol/L (P < .05), respectively. ALP levels were similar. CONCLUSION iPTH(15) value and iPTH(%) rate accurately predicts the completeness of resection in secondary hyperparathyroidism. The rate of decrease in serum iPTH detected intraoperatively compared to preoperative baseline levels exceeding 90% in sPx, 95% in tPx, accurately predicts the success of surgery. Postoperative normocalcemia without calcium replacement would raise a suspicion about completeness of surgical resection.

Abstract
BACKGROUND The purpose of this study was to determine if radioguided parathyroidectomy (RGP) is effective for hyperparathyroidism (HPT) in the reoperative neck. METHODS We retrospectively reviewed all patients with HPT and a history of neck surgery who underwent RGP over a 7-year period. Data are reported as mean +/- SEM. RESULTS We identified 110 patients with primary (n = 94), secondary (n = 7), or tertiary (n = 9) HPT who underwent 138 previous neck operations. The average hospital stay was 0.6 +/- 0.1 days. The in and ex vivo counts obtained with the gamma probe were 310 +/- 26 and 130 +/- 13, respectively. The ex vivo percentage of background was 69% +/- 9%, and virtually all resected parathyroids had ex vivo counts > or =20%. After RGP, 96% of patients were cured, and 5% experienced complications (all transient). Cure rates after RGP decreased as the number of previous neck operations increased (P = .002). Additionally, reoperative neck patients with single adenomas were more likely to experience cure than patients with hyperplasia (P = .02). CONCLUSION These results illustrate that RGP is valuable in treatment of the reoperative neck. In addition, RGP allows similar lengths of stay, efficacy, and complication rates as those reported for patients undergoing initial parathyroidectomy.

Abstract
Re-exploration of the neck for residual or recurrent hyperparathyroidism or thyroid cancer is technically challenging and preoperative imaging is very useful for guiding surgery. For both pathologies, nuclear medicine techniques have emerged as the primary preoperative imaging modalities. The precise techniques used continue to evolve as new equipment and technology (fusion imaging) become available. The role of.

Abstract
BACKGROUND In primary hyperparathyroidism the gamma probe is effective, but its role in secondary hyperparathyroidism is unclear. We investigated the utility of the probe in the surgical management of secondary and tertiary hyperparathyroidism. METHODS The value of the probe in guiding resection of parathyroids was determined prospectively in 29 patients with secondary or tertiary hyperparathyroidism. Resected tissues with radioactivity of greater than 20% as compared with the wound bed was considered hyperfunctional parathyroid and was confirmed histologically. RESULTS The probe was helpful in guiding resection in 13% of the hyperplastic glands, including ectopic glands and those not detected preoperatively. The gamma probe confirmed the presence of hyperfunctional parathyroid after resection with a sensitivity and specificity of 97% and 92%, respectively. CONCLUSIONS The probe is particularly useful in confirming the presence of hyperfunctional parathyroids after resection. It also is useful in identifying ectopic localizations, but its value is limited in guiding surgery for secondary or tertiary disease.

Abstract
BACKGROUND Secondary hyperparathyroidism (sHPT) is common in patients with chronic renal failure. Despite the initiation of new therapeutic agents, several patients will require parathyroidectomy (PTX). Total PTX with autotransplantation of parathyroid tissue (TPTX+AT) and subtotal parathyroidectomy (SPTX) are currently considered as standard surgical procedures in the treatment of sHPT. Recurrencerates after TPTX+AT or SPTX are between 10% and 12% (median follow up: 36 months). Recent retrospective studies demonstrated a lower rate of recurrent sHPT of 0-4% after PTX without autotransplantation and thymectomy (TPTX) with no higher morbidity when compared to the standard procedures. The observed superiority of TPTX is flawed due to different definitions of outcomes, varying follow up periods and different surgical treatment strategies (with and without thymectomy). METHODS/DESIGN Patients with sHPT (intact parathyroid hormone > 10 times above the upper limit of normal) on long term dialysis (>12 months) will be randomized either to TPTX or TPTX+AT and followed for 36 months. Outcome parameters are recurrence rates of sHPT, frequencies of reoperations due to refractory hypoparathyroidism or recurrent/persistent hyperparathyroidism, postoperative morbidity and mortality and quality of life. 50 patients per group will be randomized in order to obtain relevant frequencies of outcome parameters that will form the basis for a large scale confirmatory multicentred randomized controlled trial. DISCUSSION sHPT is a disease with a high incidence in patients with chronic renal failure. Even a small difference in outcomes will be of clinical relevance. To assess sufficient data about the rate of recurrent sHPT after both methods, a multicentred, randomized controlled trial (MRCT) under standardized conditions is mandatory. Due to the existing uncertainties the calculated number of patients necessary in each treatment arm (n > 4000) makes it impossible to perform this study as a confirmatory trial. Therefore estimates of different outcomes are performed using a pilot MRCT comparing 50 versus 50 randomized patients in order to establish a hypothesis that can be tested thereafter. If TPTX proves to have a lower rate of recurrent sHPT, no relevant disadvantages and no higher morbidity than TPTX+AT, current surgical practice may be changed.

Abstract
BACKGROUND Parathyromatosis is defined as multiple foci of benign hyperfunctioning parathyroid tissue in the neck or mediastinum. Parathyromatosis is a problematic cause of recurrent hyperparathyroidism (HPT). In renal HPT, the stimuli of the parathyroid cells persist after parathyroidectomy (PTx), and for this reason, parathyromatosis might be important in renal HPT. METHODS Between July 1973 and December 2005, 1,932 patients underwent PTx for advanced renal HPT in our department. We evaluated the frequency, clinical findings and the prognosis of this kind of parathyroid disorder. RESULTS After total PTx with forearm autograft for renal HPT, which was performed initially in our department, the risk for developing parathyromatosis was 0.11% (2/1837); after sub-total PTx, it was 5% (1/20). The risk for developing parathyromatosis was lower after total PTx with forearm autograft than after sub-total PTx (P < 0.05). In patients who developed persistent or recurrent HPT and were referred to our department for neck re-operation, parathyromatosis occurred in 12.1% (7/58); in those originally operated on at our hospital, the corresponding figure was 7.1% (3/42). This difference was not significant (P = 0.42). Only in 4 of 10 patients was parathyromatosis suggested before re-operation. However, in spite of several re-operations, high parathyroid hormone (PTH) levels persisted in 6 of 10 patients with parathyromatosis. CONCLUSION Parathyromatosis is a non-negligible cause of recurrent renal HPT in patients who require neck re-exploration. Parathyromatosis is difficult to diagnose pre-operatively and completely controlled by re-operation. Parathyromatosis should be kept in mind when performing neck re-exploration for recurrent renal HPT.

Abstract
INTRODUCTION Re-operation for hyperparathyroidism (HPT) represents a challenge for experienced endocrine surgeons. The present study reviews the technical and pathological factors for failure of initial surgery and identifies strategies to approach re-operative parathyroidectomy. METHODS Clinical details, operation notes, pathology, localization studies and complications for re-operative cases performed by three surgeons were reviewed. RESULTS Over a 10-year period there were 40 re-operative cases with a 98% success rate. There were 31 patients with primary HPT, 21 with persistent primary (PP) and 10 with recurrent primary (RP). Multigland disease (MGD) was present in 19 of the 31 (61%) primary HPT cases. The culprit gland was ectopic in 14 cases, at a normal location in 10 and there was regrowth at previously excised sites or remnant disease in 10. There were nine patients with secondary HPT, four with persistent secondary (PS) and five with recurrent secondary (RS). The culprit gland was ectopic in five, at a normal location in four and regrowth at a previously excised site in two. Pre-operative investigations were employed in all cases and the most helpful were sestamibi scan (S) and selective venous sampling (SVS) for parathyroid hormone (PTH) concentration. True positive localizations for S was in 20 of 34 cases (59%), SVS in seven of nine (78%), computed tomography (CT) in seven of 17 (41%) and ultrasound scan (USS) in 10 of 28 (36%). CONCLUSIONS Re-operative parathyroidectomy can be performed by experienced surgeons with a very high success rate and minimal complications.

Abstract
Multiple endocrine neoplasia type I is a rare autosomal dominant disorder with many endocrine and nonendocrine manifestations. Hyperparathyroidism, islet cell tumors, and pituitary tumors are diagnosed most commonly in these patients. There is controversy regarding treatment of the different manifestations and screening modalities of this disorder because no large series has determined the best therapeutic approach. Our institution advocates early screening with biochemical and radiographic testing in patients with a definite predilection for this disorder. Patients with hyperparathyroidism should undergo early surgical intervention of at least three and a half glands combined with bilateral upper thymectomy through a cervical incision. Although the recurrence rate is high, disease-free survival can be for as long as 30 years. Pituitary tumors are predominantly prolactinomas and growth hormone-releasing tumors. Prolactinomas usually require pharmacologic therapy, whereas growth hormone-releasing tumors are treated surgically. Enteropancreatic tumors should be treated surgically or medically, depending on the hormone secreted. Insulinomas respond well to distal pancreatectomy, with enucleation of the tumor from the head and uncinate process of the pancreas. However, there is controversy regarding the surgical treatment of gastrinomas. Carcinoid tumors should be treated with early surgical intervention. Adrenal lesions are thought to occur in association with pancreatic lesions and commonly have an indolent course. Adrenocortical cancers are uncommon in patients with multiple endocrine neoplasia type I. Skin lesions can be excised when cosmetically unappealing.

Abstract
Most patients with renal failure maintained on chronic dialysis have elevated parathyroid hormone (PTH) levels and PTH-mediated bone disease (secondary hyperparathyroidism [sHPT]). Elevated PTH production in this setting represents a progressive, exaggerated physiologic response to hypocalcemia by the parathyroid glands, and generalized growth of the parathyroids is an adaptive response to chronic stimulation. Effective medical strategies to reduce PTH secretion and PTH-mediated bone turnover in sHPT (eg, controlling hyperphosphatemia, normalizing serum calcium, and administering vitamin D analogs) has decreased the need for parathyroidectomy in recent years. However, failure of medical therapy because of inadequate treatment, persistent hyperphosphatemia, or acquired parathyroid neoplasia still leads to recommendations for parathyroidectomy in select patients. Furthermore, increased awareness of potential long-term, irreversible cardiovascular effects of uncorrected hyperparathyroidism has led some to advocate parathyroidectomy earlier in the course of this disease. This monograph will review parathyroidectomy for secondary and tertiary hyperparathyroidism.
