Abstract
This article report a 40-year-old male patient who underwent total thyroidectomy and forearm auto-transplantation in another hospital for secondary hyperparathyroidism. After 4 years of follow-up, the level of parathyroid hormone continued to increase, and ultrasound showed nodules in the neck and right forearm, which were considered to be of parathyroid origin. Technetium 99m sestamibi single photon emission computed tomography and computed tomography (Tc-99m-MIBI SPECT/CT) imaging showed increased radioactive uptake in the submuscular soft tissue nodule of the right medial forearm, maximum standardized uptake value (SUVmax) is 0.98, which was identified as transplanted functioning parathyroid tissue. No parathyroid imaging activity was found in the neck. The patient then underwent partial removal of ectopic parathyroid tissue from the right forearm. Pathological examination confirmed parathyroid tissue, and removal was followed by a rapid decline in serum parathyroid hormone levels.

[PMID: 38050273 PMCID: PMC10695584 DOI: 10.1097/md.0000000000036422] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Accepted: 11/10/2023] [Indexed: 12/06/2023] Open
Abstract
BACKGROUND Regarding the thermal ablation treatment of refractory secondary hyperparathyroidism (SHPT), there is no consensus on the ablation range of the hyperplastic parathyroid gland. Therefore, this meta-analysis was conducted to evaluate the efficacy and complications between full and partial thermal ablation in patients with refractory SHPT. METHODS Databases including PubMed, EMbase, the Cochrane Library, CNKI (China National Knowledge Infrastructure), and Wanfang databases were searched from inception to July 1, 2023. Eligible studies comparing full thermal ablation and partial thermal ablation for SHPT were included. Data were analyzed using Review Manager Version 5.3. RESULTS Four studies were included in the meta-analysis. Three cohort studies and one randomized controlled trial involving 62 patients in the full thermal ablation group and 63 patients in the partial thermal ablation group were included. The serum parathyroid hormone (PTH), calcium, and phosphorus levels after full ablation were all lower than those after partial ablation (P < .05). There was no significant difference between the partial and full ablation groups concerning the incidence rate of severe hypocalcemia (P = .09). There was no significant difference between the partial and full ablation groups concerning symptom improvement, including bone joint pain, itching, and myasthenia (P < .05). CONCLUSION Full ablation was superior to partial ablation in terms of reducing PTH, calcium and phosphorus levels. Full ablation might not significantly increase the incidence of severe hypocalcemia. Larger multicentre randomized controlled trials are necessary to confirm the conclusion.

Abstract
PURPOSES Surgery remains an important treatment option for renal hyperparathyroidism (rHPT). The number of long-term outcome studies of parathyroidectomy is limited. METHODS All consecutive patients with a parathyroidectomy for rHPT between 09/2009 and 04/2021 in a Belgian tertiary referral hospital were prospectively enrolled. The main outcomes were (long-term) cured proportion and postoperative morbidity (hypocalcemia, recurrent laryngeal nerve (RLN) palsy, re-intervention for bleeding, and wound morbidity). RESULTS Sixty patients with a median age of 57 years were analyzed, including 23 patients before kidney transplantation, 23 patients without kidney transplantation, and 14 patients after kidney transplantation. Median time to transplant was 15 (6-24) months after parathyroidectomy. Morbidity was low with only two non-urgent returns to theatre (wound infection and non-compressive hematoma), two temporary RLN paralyses, and no 30-day mortality. Length of hospital stay was longer in patients with parathyroidectomy before kidney transplant, due to a more severe and prolonged need for calcium supplementation. After a median follow-up of 63 months, 37 patients (62%) were still alive, and 11 patients (18%) developed a recurrence. CONCLUSIONS This single-surgeon, single-center cohort with long-term follow-up confirms the safety and excellent 'cure' proportions of surgery for rHPT but stretches the importance of long-term follow-up.

Abstract
Secondary hyperparathyroidism (SHPT) is a major problem for patients with chronic kidney disease and can cause many complications, including osteodystrophy, fractures, and cardiovascular diseases. Treatment for SHPT has changed radically with the advent of calcimimetics; however, parathyroidectomy (PTx) remains one of the most important treatments. For successful PTx, removing all parathyroid glands (PTGs) without complications is essential to prevent persistent or recurrent SHPT. Preoperative imaging studies for the localization of PTGs, such as ultrasonography, computed tomography, and 99mTc-Sestamibi scintigraphy, and intraoperative evaluation methods to confirm the removal of all PTGs, including, intraoperative intact parathyroid hormone monitoring and frozen section diagnosis, are useful. Functional and anatomical preservation of the recurrent laryngeal nerves can be confirmed via intraoperative nerve monitoring. Total or subtotal PTx with or without transcervical thymectomy and autotransplantation can also be performed. Appropriate operative methods for PTx should be selected according to the patients' need for kidney transplantation. In the case of persistent or recurrent SHPT after the initial PTx, localization of the causative PTGs with autotransplantation is challenging as causative PTGs can exist in the neck, mediastinum, or autotransplanted areas. Additionally, the efficacy and cost-effectiveness of calcimimetics and PTx are increasingly being discussed. In this review, medical and surgical treatments for SHPT are described.

Abstract
BACKGROUND Parathyroidectomy (PTx) is the most effective treatment for secondary hyperparathyroidism. Literature regarding the effect of surgical approaches on postoperative hypocalcemia is limited and mainly focuses on postoperative calcium levels. This study aims to evaluate the association of subtotal PTx and total PTx with autotransplantation for secondary hyperparathyroidism with postoperative hypocalcemia. STUDY DESIGN We reviewed all dialysis patients who underwent PTx (n = 143) at our institution from 2010 to 2021. Postoperative hypocalcemia adverse events were defined as postoperative intravenous calcium requirement or 30-day readmission due to hypocalcemia. Postoperative hypocalcemia adverse events, length of stay, and oral calcium requirement at 1-month follow-up were compared between the 2 groups. RESULTS Of the 143 patients, 119 (83.2%) underwent total PTx with autotransplantation, and 24 (16.8%) underwent subtotal PTx. Patients who underwent subtotal PTx had shorter mean ± SD length of stay (1.8 ± 1.7 vs 3.5 ± 3.2, p = 0.002), were less likely to develop hypocalcemia adverse events (8.3% vs 47.1%, p < 0.001), and required less median elemental calcium supplementation at 1-month follow-up (1,558 vs 3,193 mg, p < 0.001). There was no significant difference in surgical success between the 2 groups (91.7% vs 89.1%, p = 0.706). Stepwise multivariable regression demonstrated that patients who underwent total PTx with autotransplantation were 11.9 times more likely to develop hypocalcemia adverse events (adjusted odds ratio 11.9, 95% CI 2.2 to 66.2, p = 0.004), had 1.24 days longer length of stay (95% CI 0.04 to 2.44, p = 0.044), and required 1,776.1 mg more elemental calcium (95% CI 661.5 to 2,890.6 mg, p = 0.002). CONCLUSIONS Subtotal parathyroidectomy is associated with less postoperative hypocalcemia and provides similar surgical cure for dialysis patients with secondary hyperparathyroidism.

Abstract
Objective This paper aimed to evaluate the clinical value of performing an endoscopic total parathyroidectomy through anterior chest approach with autotransplantation (EACtPTx+AT) in treating secondary hyperparathyroidism (SHPT) to summarize and share the clinical experience. Methods 24 patients with SHPT were retrospectively analyzed:11 patients underwent open total parathyroidectomy with autotransplantation (OtPTx+AT Group) and 13 patients underwent endoscopic parathyroidectomy through anterior chest approach with autotransplantation (EACtPTx+AT Group). Comparing the two groups regarding the following factors: (1) operating conditions, such as the blood loss during the operation, the length of time spent on the operating table, the number of parathyroid glands removed, postoperative drainage volume and hospital stay. (2) clinical efficacy, parathyroid hormone (PTH) and serum calcium (Ca) levels. (3) postoperative complications. Results First, there were no significant differences in the number of parathyroid gland resection, operation time, intraoperative blood loss and hospital stay between the two groups. While there were significant differences in postoperative drainage volume between the two groups. Second, the two groups preoperative PTH and preoperative serum calcium decreased significantly compared with those of the two groups after surgery and there was a statistically significant difference. Thirdly, there was no postoperative bleeding, hoarseness or choking in the two groups and no conversion to open surgery case in EACtPTx+AT group. Conclusion Endoscopic treatment of SHPT using the anterior chest approach with forearm autotransplantation significantly improves clinical symptoms and lowers levels of PTH and serum calcium after the operation. The results confirm the operation's safety and effectiveness.

Abstract
OBJECTIVE Our study aimed to develop and validate a nomogram to predict severe hypocalcemia (SH) before total parathyroidectomy (TPTX) without auto-transplantation in patients with secondary hyperparathyroidism. METHODS A total of 299 consecutive patients who underwent TPTX without transplantation for secondary hyperparathyroidism were selected from the General Hospital of Northern Theater Command between January 2013 and December 2021. Of these, patients who underwent surgery between January 2013 and December 2020 formed the training cohort (n = 208) to develop a nomogram, and those who underwent surgery thereafter formed the validation cohort (n = 91) to validate the performance of this nomogram. Univariate and multivariate logistic regression analyses were used to identify the risk factors associated with SH, and then, a nomogram was constructed. RESULTS The incidence of postoperative SH was 27.9% and 35.2% in the training and validation cohorts, respectively. The preoperative factors associated with SH were younger age, lower serum calcium (Ca) level, higher intact parathyroid hormone (iPTH) level, and higher serum alkaline phosphatase (ALP) level. Incorporating these 4 factors, the nomogram achieved good concordance indexes of 0.866 (95%CI, 0.816-0.916) and 0.867 (95% CI, 0.793-0.941) in predicting SH in the training and validation cohorts, respectively, and had well-fitted calibration curves. The positive predictive values of the nomogram were 64.7% (54.1%-78.4%) and 75.0% (58.6%-88.5%), and negative predictive values of the nomogram were 90.0% (82.9%-93.6%) and 86.4% (73.5%-94.0%) for the training and validation cohorts, respectively. CONCLUSIONS We developed and validated a nomogram for the prediction of SH in patients who underwent TPTX without auto-transplantation for secondary hyperparathyroidism. Our nomogram may facilitate the identification of high-risk SH in patients after TPTX and optimization of preoperative decision-making.

Abstract
Background Surgical parathyroidectomy (PTX) is necessary for patients with severe and progressive secondary hyperparathyroidism (SHPT) refractory to medical treatment. Recurrence of SHPT after PTX is a serious clinical problem. Both supernumerary mediastinal parathyroid gland and parathyromatosis are the rare causes of recurrent renal SHPT. We report a rare case of recurrent renal SHPT due to supernumerary mediastinal parathyroid gland and parathyromatosis. Case presentation A 53-year-old man underwent total parathyroidectomy with autotransplantation due to the drug-refractory SHPT 17 years ago. In the last 11 months, the patient experienced symptoms including bone pain and skin itch, and the serum intact parathyroid hormone (iPTH) level elevated to 1,587 pg/ml. Ultrasound detected two hypoechoic lesions located at the dorsal area of right lobe of the thyroid gland, and both lesions presented as characteristics of hyperparathyroidism in contrast-enhanced ultrasound. 99mTc-MIBI/SPECT detected a nodule in the mediastinum. A reoperation involved a cervicotomy for excising parathyromatosis lesions and the surrounding tissue and a thoracoscopic surgery for resecting a mediastinal parathyroid gland. According to a histological examination, two lesions behind the right thyroid lobe and one lesion in the central region had been defined as parathyromatosis. A nodule in the mediastinum was consistent with hyperplastic parathyroid. The patient remained well for 10 months with alleviated symptoms and stabilized iPTH levels in the range of 123-201 pg/ml. Conclusion Although rare, recurrent SHPT may be caused by a coexistence of both supernumerary parathyroid glands and parathyromatosis, which should receive more attention. The combination of imaging modalities is important for reoperative locations of parathyroid lesions. To successfully treat parathyromatosis, all the lesions and the surrounding tissue must be excised. Thoracoscopic surgery is a reliable and safe approach for the resection of ectopic mediastinal parathyroid glands.

Abstract
Kidney transplantation remains the best treatment for patients with end-stage kidney disease, and it could partially mitigate systemic disorders of mineral and bone metabolism caused by secondary hyperparathyroidism. However, persistent hyperparathyroidism is still observed in 30-60% of patients 1 year after kidney transplantation, leading to impairment of allograft function and a disturbance of mineral metabolism. The timing of parathyroidectomy varies among transplant centers because the possible negative effects of parathyroidectomy on allograft outcomes are still unclear. This review provides a comprehensive and detailed overview of the natural course of hyperparathyroidism following kidney transplantation and the effects of the timing and extent of parathyroidectomy on allograft function. It aims to provide useful information for surgeons to propose an appropriate intervention strategy to break the vicious cycle of post-kidney transplantation hyperparathyroidism and deterioration of allograft function.

Abstract
BACKGROUND Total parathyroidectomy (PTx) is often performed to treat secondary hyperparathyroidism (SHPT). Successful PTx is essential to prevent recurrent and persistent SHPT because remnant parathyroid glands (PTGs) in the neck can be stimulated and may secrete excessive parathyroid hormone (PTH) in end-stage renal disease. However, to date, few studies have investigated factors contributing to successful PTx before the completion of surgery. MATERIALS AND METHODS Between August 2010 and February 2020, 344 patients underwent total PTx, transcervical thymectomy, and forearm autograft for SHPT at our institute. Factors contributing to successful PTx before the completion of surgery were investigated. Preoperative imaging diagnoses, including computed tomography, ultrasonography, technetium-99m methoxyisobutylisonitrile (99mTc-MIBI) scintigraphy, intraoperative intact PTH (IOIPTH) monitoring, and frozen section histologic diagnosis, were performed. Successful PTx was defined as intact PTH level < 60 pg/mL on postoperative day 1. A sufficient decrease in IOIPTH level was defined as > 70% decrease in intact PTH levels measured 10 min after total PTx and transcervical thymectomy compared to intact PTH levels measured before skin incision. Logistic regression analysis was conducted to investigate factors contributing to PTx success. RESULTS Univariate analysis showed that the number of all PTGs identified preoperatively by imaging modalities and the specimens submitted for frozen section diagnosis, which surgeon presumed to be PTGs, were not significant factors contributing to successful PTx. However, multivariate analysis revealed that the number of PTGs identified by frozen section diagnosis (P < 0.001, odds ratio [OR] 4.356, 95% confidence interval [CI] 2.499-7.592) and sufficient decrease in IOIPTH levels (P = 0.001, OR 7.847, 95% CI 2.443-25.204) significantly contributed to successful PTx. CONCLUSION Sufficient intact PTH level decrease observed on IOIPTH monitoring and the number of PTGs identified by frozen section diagnosis contributed to successful PTx for SHPT. IOIPTH monitoring and frozen section diagnosis are essential for achieving successful PTx for SHPT.

[PMID: 36331700 PMCID: PMC10105684 DOI: 10.1007/s11255-022-03401-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Accepted: 10/17/2022] [Indexed: 11/06/2022]
Abstract
Abstract
Purpose
To investigate the therapeutic efficacy, feasibility, and safety of total parathyroidectomy (tPTX) in the treatment of secondary hyperparathyroidism (SHPT).
Methods
The clinical data of 34 SHPT patients admitted to the Department of Nephrology, Yuxi People’s Hospital, from January 2018 to January 2021 who had received tPTX, were retrospectively analyzed. The indications for tPTX were severe SHPT that did not respond to medical treatment and was ineligible for kidney transplantation. tPTX without autotransplantation was adopted to compare the level of symptom relief and changes in serum intact parathyroid hormone (iPTH), blood calcium, and blood phosphorus pre- and postoperatively.
Results
In 34 patients, 142 parathyroid glands were removed, including 21 ectopic parathyroid glands (14.78%). Six patients (17.64%, 6/34) had supernumerary parathyroid glands. At 6 h postoperatively, arthralgia and bone pain were significantly reduced to almost zero in 94.12% (32/34) of patients. At 24 h postoperatively, relief of bone pain and improvement of limb movement were observed in 100% (34/34) of patients, and pruritus almost disappeared in 86.36% (19/22) of patients. There were significant differences in iPTH (χ2 = 134.93, P < 0.05), calcium (χ2 = 23.02, P < 0.05), and phosphorus (χ2 = 102.11, P < 0.05) levels preoperatively and 40 min, 24 h, 1 week, half a year, and last available (> 1 year) postoperatively.
The patients were followed up for 15–47 months (median 33 months). Hypoparathyroidism was observed in three patients, who underwent neck dissection or partial thymotomy concurrently for different reasons. No intractable hypocalcemia or adynamic bone disease occurred during the follow-up period.
Conclusion
In SHPT patients who were ineligible for renal transplantation, tPTX was effective, safe, and reliable, with a low recurrence rate. However, when tPTX was performed alone without autologous transplantation, bilateral neck exploration was sufficient, and central neck dissection and thymic resection were inadvisable.

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.

A predictive risk score to diagnose hypocalcemia after parathyroidectomy in patients with secondary hyperparathyroidism: a 22-year retrospective cohort study. Sci Rep 2022; 12:9548. [PMID: 35681076 PMCID: PMC9184730 DOI: 10.1038/s41598-022-13880-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Accepted: 05/30/2022] [Indexed: 11/30/2022] Open
Abstract
Hypocalcemia is a common complication found in patients with secondary hyperparathyroidism (SHPT) who undergo parathyroidectomy. This study aimed to construct a predictive risk score for the occurrence of hypocalcemia after parathyroidectomy in patients with SHPT who underwent chronic renal replacement therapy (RRT). This 22-year retrospective cohort study enrolled 179 patients with SHPT who had their first parathyroidectomy. Eighty-two percent of patients developed hypocalcemia within 16.9 (95% CI 14.5–19.5) h after parathyroidectomy. This study demonstrated four factors as independent risk factors for post-parathyroidectomy hypocalcemia, including duration of RRT, preoperative serum phosphate, preoperative serum alkaline phosphatase (ALP) and mean difference of serum intact parathyroid hormone (iPTH). By using logistic regression analysis, this study demonstrated cut-off points for these four risk factors for the diagnosis of hypocalcemia after parathyroidectomy: 5 years for the duration of RRT, 5 mg/dL for serum phosphate, 387 U/L for serum ALP, and 97% for the mean difference of serum iPTH. Finally, the predictive risk score was constructed by assigning a score of one to each factor. With a total score of at least 2, the proposed predictive risk score has an AuROC of 0.755 with a sensitivity of 78.2%, a specificity of 71.4%, and an accuracy of 76.9%.

Abstract
BACKGROUND To compare the short-term clinical outcomes of ultrasound-guided microwave ablation (MWA) and parathyroidectomy (PTX) for severe secondary hyperparathyroidism(SHPT). METHODS In a prospective multi-center study, we compared the outcomes of MWA and PTX for severe SHPT. The outcome measures were case rate of successful treatment, improvement of clinical symptoms, incidence of complications, and differences in treatment parameters and costs between the two groups. RESULTS A total of 167 eligible patients were included in the study, of which 79 underwent MWA and 88 underwent PTX. There was no significant difference in rate of successful treatment between the MWA and PTX groups (χ2=2.299, p = 0.125). However, the MWA group showed significantly lower range of intact parathyroid hormone (iPTH) decrease than the PTX group (t=-2.352, p = 0.023). Postoperative clinical symptoms improved in both groups, with no significant difference between the two groups (p > 0.05). Postoperative hypocalcemia was significantly more common in the PTX group (p < 0.05). The operative time, incision and postoperative pain of the MWA group were significantly better than those of the PTX group (p < 0.05), while postoperative recurrent laryngeal nerve injury and hematoma showed no significant difference between the two groups (p > 0.05). The cost of MWA was significantly less than PTX (p = 0.000). CONCLUSIONS Both MWA and PTX are effective and safe for severe secondary hyperparathyroidism. PTX is more thorough and traumatic, while MWA is minimally invasive and postoperative iPTH is more consistent with the Kidney Disease: Improving Global Outcomes (KDIGO) recommendation.

Ultrasound-guided bilateral superficial cervical plexus block enhances the quality of recovery of uremia patients with secondary hyperparathyroidism following parathyroidectomy: a randomized controlled trial. BMC Anesthesiol 2021; 21:228. [PMID: 34536993 PMCID: PMC8449502 DOI: 10.1186/s12871-021-01448-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2020] [Accepted: 09/08/2021] [Indexed: 02/07/2023] Open
Abstract
Background Parathyroidectomy has been proposed as a method for reducing parathyroid hormone levels. We evaluated the effects of ultrasound-guided bilateral superficial cervical plexus block (BSCPB) on the quality of recovery of uremia patients with secondary hyperparathyroidism (SHPT) following parathyroidectomy. Methods Eighty-two uremia patients who underwent parathyroidectomy and exhibited SHPT were randomly allocated to the BSCPB group or the control group (CON group). The patients received ultrasound-guided BSCPB with 7.5 ml of ropivacaine 0.5% on each side (BSCPB group) or equal amount of 0.9% normal saline (CON group). The primary outcome of the Quality of Recovery-40(QoR-40) score was recorded on the day before surgery and postoperative day 1(POD1). Secondary outcomes including total consumption of remifentanil, time to first required rescue analgesia, number of patients requiring rescue analgesia, and total consumption of tramadol during the first 24 h after surgery were recorded. The occurrence of postoperative nausea or vomiting (PONV) and the visual analogue scale (VAS) scores were assessed and recorded. Results The scores on the pain and emotional state dimensions of the QoR-40 and the total QoR-40 score were higher in the BSCPB group than in the CON group on POD1 (P = 0.000). Compared with the CON group, the total consumption of remifentanil was significantly decreased in the BSCPB group (P = 0.000). The BSCPB group exhibited longer time to first required rescue analgesia (P = 0.018), fewer patients requiring rescue analgesia (P = 0.000), and lower postoperative total consumption of tramadol during the first 24 h after surgery (P = 0.000) than the CON group. The incidence of PONV was significantly lower in the BSCPB group than in the CON group (P = 0.013). The VAS scores in the BSCPB group were lower than those in the CON group at all time-points after surgery (P = 0.000). Conclusion Ultrasound-guided BSCPB with ropivacaine 0.5% can enhance the quality of recovery, postoperative analgesia, and reduce the incidence of PONV in uremia patients with SHPT following parathyroidectomy.

Abstract
Background The aim of this study is to evaluate the effect of ultrasound-guided bilateral cervical plexus block on general anesthesia, postoperative analgesia, and surgical outcomes in patients undergoing total parathyroidectomy with autotransplantation. Patients and Methods Forty-eight ASA III–IV patients with hyperparathyroidism secondary to renal failure were included: 24 patients received ultrasound-guided bilateral superficial and deep cervical plexus block combined with general anesthesia (group A), and 24 patients received general anesthesia alone (group B). Postoperative patient-controlled intravenous analgesia was provided with sufentanil 2 μg/kg. The primary outcome is the postoperative pain scores. Secondary outcomes include intraoperative remifentanil dosage, changes in hemodynamics, extubation time, and sufentanil consumption. Surgical outcomes regarding calcium, phosphorus and parathormone values were also noted. Results The patients in group A required less remifentanil than group B (2.56±0.92mg vs 3.38±0.84mg, P=0.002) and lower VAS scores at 1, 3, 10, 24, and 48h postoperatively (P < 0.001). While the systolic blood pressure in group A patients was significantly greater than that in group B at T3 (immediately after extubation, [138.33±11.36 vs 129.08±17.06 mmHg; P=0.032]), heart rates in group A were lower than in group B at 1 min before induction (T1 [89.46 ± 9.14 vs 96.71±14.19, P=0.042]) and 1 min after intubation (T2 [70.08 ± 5.35 vs 79.25 ± 11.81, P=0.002]). The extubation time in group A was shorter than that in group B (P < 0.001). There was no difference in calcium, phosphorus and parathormone values, nor in sufentanil consumption between the groups. Conclusion Ultrasound-guided bilateral superficial and deep cervical plexus block combined with general anesthesia for TPTA is an effective strategy to improve anesthesia management and achieve better postoperative analgesia, and has no impact on surgical outcomes.

Abstract
Background Drug-refractory secondary hyperparathyroidism (SHPT) is the most common complication in patients with chronic renal failure (CRF). Although surgery is the most effective and safe method for drug-refractory SHPT, the condition may persist or recur after the primary surgery, and reoperation is often required in these patients. The purpose of our current study was to evaluate the safety and effectiveness of reoperation for drug-refractory SHPT. Methods The clinical data of 15 patients requiring reoperation after a surgery for drug-refractory SHPT in our hospital from 2010 to 2019 were retrospectively analyzed. Changes in biochemical markers including intact parathyroid hormone (iPTH), blood calcium (Ca), blood phosphorus (P), alkaline phosphatase (ALP), and blood calcium phosphorus product (Ca*P) were compared before and after the surgery, and the effectiveness and complications of the reoperation were summarized. Results The reoperation was successful in all the 15 patients after a single attempt. Routine pathological examinations identified a total of 25 parathyroid glands, of which 10 were in the neck in situ, 5 were ectopic in the neck, and 10 were in the forearm. The ectopic parathyroid glands were located inside the thyroid gland (n=1), anterior superior mediastinum (n=1), or thymus (n=3). Surgical treatment significantly improved clinical symptoms such as skin pruritus and bone pain. Blood iPTH, Ca, P, ALP, and Ca*P were significantly reduced (P<0.05 or P<0.01) after surgery. Hypothyroidism occurred in 1 patient; 4 patients undergoing orthotopic neck surgery developed transient hoarseness, which were alleviated within 6 months; no severe complications such as bleeding or death were noted. No recurrence occurred during the 6-month follow-up. Conclusions Reoperation is safe and effective for drug-refractory SHPT. Preoperative imaging should be performed to achieve accurate positioning, and the recurrent laryngeal nerve should be closely monitored during surgery. The purpose of the reoperation is to remove all possible parathyroid tissues to avoid recurrence.
