Abstract
BACKGROUND The most important factors affecting the development of postoperative hypocalcaemia (PH) include intraoperative trauma to the parathyroid glands, incidental parathyroidectomy (IP), and the surgeon's experience. In this study, we aimed to determine the incidence of IP, evaluate its effect on postoperative calcium levels and investigate the effect of surgeon experience and volume on IP incidence and postoperative calcium levels. METHODS This retrospective study included 645 patients who underwent thyroid surgery at the Department of General Surgery, Kütahya Health Sciences University between September 2016 and March 2020. All patients underwent surgery at a single clinic by general surgeons experienced in thyroid surgery and their residents (3-5 years). RESULTS Normal parathyroid glands were reported in 58 (8.9%) of 645 patients. In 5 (8.6%) of 58 patients the parathyroid gland was detected in the intrathyroidal region. PH developed in ten patients (17.2%) with incidental removal of the parathyroid glands. A statistically significant difference was found between the number of incidentally removed parathyroid glands and the development of hypocalcaemia (p<0.05). Normal parathyroid glands were reported in the pathology of 37 (7.9%) patients operated on by general surgeons and 22 (12.6%) patients operated on by their residents. PH developed in 39 (8.2%) patients operated on by general surgeons and in 8 (4.5%) patients operated on by their residents. CONCLUSIONS We found that the complication rate during the resident training process was the same as that of experienced general surgeons. A thyroidectomy can be safely performed by senior residents during residential training.

The significance of short-term preoperative calcium and activated vitamin D3 supplementation in thyroidectomy: a randomized trial and prospective study. Endocr Connect 2024; 13:e230377. [PMID: 37947264 PMCID: PMC10762556 DOI: 10.1530/ec-23-0377] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Accepted: 11/09/2023] [Indexed: 11/12/2023]
Abstract
Objective The aim was to explore the effects of preoperative calcium and activated vitamin D3 supplementation on post-thyroidectomy hypocalcemia and hypo-parathyroid hormone-emia (hypo-PTHemia). Methods A total of 209 patients were randomly divided into control group (CG) and experimental group (EG). Oral calcium and activated vitamin D3 supplementation were preoperatively administered to EG, whereas a placebo was administered to CG. Data on serum calcium, phosphorus, and PTH concentrations before operation, on postoperative day 1 (POPD1), at postoperative week 3 (POPW3), and on the length of postoperative hospitalization were collected. Results The serum calcium, phosphorus, and PTH concentrations, as well as the incidence of postoperative hypocalcemia and hypo-PTHemia, did not significantly differ between EG and CG. Subgroup analysis revealed that the serum calcium concentrations of the experimental bilateral thyroidectomy subgroup (eBTS) on POPD1 and POPW3 were higher than that of the control bilateral thyroidectomy subgroup (cBTS) (P < 0.05); the reduction of serum calcium in eBTS on POPD1 and POPW3 was less than those in cBTS (P < 0.05). However, significant differences were not observed between the unilateral thyroidectomy subgroups (UTS) (P > 0.05). Moreover, the incidence of postoperative hypocalcemia in cBTS on POPD1 was significantly higher than that in eBTS (65.9% vs 41.7%) (P < 0.05). The length of hospitalization in cBTS (3.55 ± 1.89 days) was significantly longer than that (2.79 ± 1.15 days) in eBTS (P < 0.05). Conclusion Short-term preoperative prophylactic oral calcium and activated vitamin D3 supplementation could effectively reduce the incidence of postoperative hypocalcemia and decrease the length of postoperative hospitalization in patients who have undergone bilateral thyroidectomy.

Abstract
OBJECTIVES To evaluate the incidence of inadvertent parathyroidectomy, identify risk factors, determine the location of inadvertently excised glands, review pathology reporting in inadvertent parathyroidectomy, and explore relationships between inadvertent parathyroidectomy and post-surgical hypoparathyroidism or hypocalcaemia. METHODS A retrospective cohort study of 899 thyroidectomies between 2015 and 2020 was performed. Histopathology slides of patients who had an inadvertent parathyroidectomy and a random sample of patients without a reported inadvertent parathyroidectomy were reviewed. RESULTS Inadvertent parathyroidectomy occurred in 18.5 per cent of thyroidectomy patients. Central neck dissection was an independent risk factor (inadvertent parathyroidectomy = 49.4 per cent with central neck dissection, 12.0 per cent without central neck dissection, p < 0.001). Most excised parathyroid glands were extracapsular (53.3 per cent), followed by subcapsular (29.1 per cent) and intrathyroidal (10.9 per cent). Parathyroid tissue was found in 10.2 per cent of specimens where no inadvertent parathyroidectomy was reported. Inadvertent parathyroidectomy was associated with a higher incidence of six-month post-surgical hypoparathyroidism or hypocalcaemia (19.8 per cent who had an inadvertent parathyroidectomy, 7.7 per cent without inadvertent parathyroidectomy). CONCLUSION Inadvertent parathyroidectomy increases the risk of post-surgical hypoparathyroidism or hypocalcaemia. The proportion of extracapsular glands contributing to inadvertent parathyroidectomy highlights the need for preventative measures.

Abstract
PURPOSE Transient hypoparathyroidism is the most common complication after total thyroidectomy, and accidental parathyroidectomy (AP) may be a cause. The aim of this study was to investigate the incidence of AP and its impact on postoperative calcemia. MATERIALS AND METHODS From February 2016 to May 2018, 766 patients undergoing total thyroidectomy were prospectively included. Surgical indications, hormonal status, definitive histology, and postoperative calcium and PTH levels were analyzed. RESULTS 578/(75.45%) were women and 188/(24.55%) men with mean age of 53.4 years. Parathyroid tissue on the thyroid specimen was observed in 40 (5.2%) patients: 30 APs and 10 parathyroid fragments. Among the 30 APs, 12 glands were intrathyroid and 18 (2.3%) in eutopic location. 97 (12.6%) patients were treated for postoperative hypocalcemia: 90 (11.7%) had transient and 5 (0.6%) definitive hypoparathyroidism; 2 were lost in follow-up. 13/30 (43.3%) with AP had transient hypoparathyroidism. A strong correlation was found (p < 0.0001) between AP and postoperative hypocalcemia. 1/30 (3.3%) patient with APs had definitive hypoparathyroidism. Transient and persistent nerve palsies were found in 10 (1.3%) and 3 (0.4%) patients, respectively. DISCUSSION A careful examination of the thyroid gland after resection help to identify an AP that could be autotransplanted. Surgeon and hospital activity volume per years seem to reduce the risk of hypoparathyroidism. CONCLUSION Total thyroidectomy and intrathyroid localization of parathyroid glands are risk factors for the AP. The incidence of AP was 2.3%, and this remains low due to our longstanding experience in thyroid and parathyroid surgery.

Abstract
INTRODUCTION Iatrogenic hypoparathyroidism following thyroidectomy is one of the most common complications significantly reducing patients' quality of life. OBJECTIVES This study aimed to analyze the risk factors for calcium-phosphate disorders following thyroidectomy. PATIENTS AND METHODS The study group consisted of 211 patients who underwent thyroidectomy for different conditions in 2018-2020. Demographic, clinical and surgical risk factors were analyzed against hypoparathyroidism and hypocalcemia. RESULTS Hypoparathyroidism occurred in 15.63% of patients, and hypocalcemia occurred in 45% of those operated on. There was statistical significance between hypoparathyroidism and the extent of thyroid surgery: thyroidectomy vs. lobectomy (p = 0.02, OR = 4.5) and surgeon experience (p = 0.016, OR = 6.9). Low preoperative PTH levels were associated with a higher incidence of hypoparathyroidism (p = 0.055, OR = 0.9). There was a statistically significant correlation between the occurrence of hypocalcemia and preoperative vitamin D deficiency (p = 0.04, OR = 3.5). Low calcium levels before surgery were associated with a higher incidence of hypocalcemia (p = 0.051, OR = 0.5). Meta-analyses of selected risk factors confirmed that the most significant factor in the incidence of hypocalcemia was a decrease in PTH levels (p < 0.001). CONCLUSIONS The extent of thyroid surgery and the experience of the surgeon are the most significant risk factors for hypoparathyroidism. Hypocalcemia is much more common than hypoparathyroidism. Among the risk factors for hypocalcemia, in addition to the decrease in parathormone levels due to iatrogenic parathyroid damage, we should mention vitamin D deficiency in the preoperative period.

Abstract
Background Thyroid surgeries, among the most common surgical procedures globally, present with varied complications. This study is aimed at identifying the complications and selected variables associated with thyroid surgery. Methods In this cross-sectional, retrospective, record-based study, a total of 107 patients who underwent thyroidectomies and satisfied the inclusion criteria, were recruited using convenience sampling technique. This study was conducted at a tertiary care hospital from January 2021 to December 2021. Data were collected from medical records using a researcher-created data extraction form after ethical approval from the institutional ethics committee. The data were analyzed using Epi Info software (Atlanta, GA: Centers for Disease Control and Prevention), with a p-value of <0.05 considered to be statistically significant. Results Of the 107 patients who underwent thyroidectomies, 92 (85.9%) reported one or more complications. Complications were most common (90.2% of patients) in the 25-34 years age group and among females (83.3%). The most common complications were dysphagia (30.84% of patients), voice change (21.50%), and respiratory obstruction (8.41%). Temporary hypocalcemia developed in 3.74% of these patients, while tracheal injury and hematoma were documented in 3.74% and 1.87%, respectively. Tobacco users (14.9%), alcohol users (16.8%), those eating a non-vegetarian diet (61.9%), and those eating saturated fats (13.0%) suffered more complications. Family history (p=0.03) was found to be significantly associated with complications. Conclusion The most common post-thyroidectomy complications in this group of patients were dysphagia and voice change, while hypocalcemia, tracheal injury, and hematoma were rare complications. Tobacco users and alcohol users reported more complications. Complications were more common in those with a family history of thyroid disease and those who were underweight.

Abstract
Objectives Thyroid gland surgery and its surgical complications are situations that a surgeon frequently encounters in his daily practice. In our study, it was aimed to examine the effect of different treatment methods given to patients who underwent thyroidectomy on hypocalcemia. Material and Methods Three hundred and seventy-one patients who underwent thyroidectomy at Ondokuz Mayıs University Medical Faculty General Surgery clinic between December 2016 and January 2021 were retrospectively included in the study. Parameters such as surgery indications, fine needle aspiration biopsy results, preoperative serum calcium values, type of surgery, serum calcium values at postoperative 1st day and 1st month, postoperative hospital stay, drugs prescribed at discharge, histopathological diagnosis of the patient, and whether there was incidental parathyroidectomy or not were included. Results Mean age of 371 patients who underwent thyroidectomy was 49 (19-82) years. Total thyroidectomy was the most common type of thyroidectomy with 61% (n= 225) of the patients. There was a significant decrease in pre-op and post-op calcium values in all three types of surgery performed on the patients, and there was no significant difference between the different types of surgery. Post-operative day one and month one serum calcium values were significantly increased in all groups (p= .000). The increase in post-op serum calcium level was most common in the group using calcium carbonate + cholecalciferol + calcitriol. Conclusion The use of post-op calcitriol in patients undergoing thyroidectomy seems to be quite effective in preventing the development of hypocalcemia.

Abstract
We have recently witnessed a rapid increase in the incidence of differentiated thyroid carcinoma (DTC), particularly low and very low-risk papillary thyroid carcinoma. Simultaneously, the number of cancer-related deaths has remained stable for more than 30 years. Such an indolent nature and long-term survival prompted researchers and experts to an ongoing discussion on the adequacy of DTC management to avoid, on the one hand, the overtreatment of low-risk cases and, on the other hand, the undertreatment of highly aggressive ones.The most recent guidelines of the American Thyroid Association (ATA GL) moved primary thyroid surgery in DTC towards a less aggressive approach by making lobectomy an option for patients with intrathyroidal low-risk DTC tumors up to 4 cm in diameter without evidence of extrathyroidal extension or lymph node metastases. It was one of the key changes in DTC management proposed by the ATA in 2015.Following the introduction of the 2015 ATA GL, the role of thyroid lobectomy in DTC management has slowly become increasingly important. The data coming from analyses of the large databases and retrospective studies prove that a less extensive surgical approach, even if in some reports it was related to a slight increase of the risk of recurrence, did not show a negative impact on disease-specific and overall survival in T1T2N0M0 low-risk DTC. There is no doubt that making thyroid lobectomy an option for low-risk papillary and follicular carcinomas was an essential step toward the de-escalation of treatment in thyroid carcinoma.This review summarizes the current recommendations and evidence-based data supporting the necessity of de-escalation of primary thyroid surgery in low-risk DTC. It also discusses the controversies raised by introducing new ATA guidelines and tries to resolve some open questions.

Does the Risk of Hypocalcemia Increase in Complementary Thyroidectomy Performed in Papillary Thyroid Cancer? SISLI ETFAL HASTANESI TIP BULTENI 2022; 56:482-488. [PMID: 36660383 PMCID: PMC9833338 DOI: 10.14744/semb.2022.91073] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Revised: 10/15/2022] [Accepted: 10/17/2022] [Indexed: 11/07/2022]
Abstract
Objectives Papillary thyroid cancer (PTC) is the most common type of thyroid cancers. In some patients, due to the histopathological features of PTC, complementary thyroidectomy (CT) may be needed to contralateral thyroid lobe after lobectomy. Hypocalcemia is the most common complication after thyroidectomy and its etiology is multifactorial. It is still controversial whether the CT increases the risk of hypocalcemia or not. In this study, we aimed to evaluate whether CT procedure increases the risk of hypocalcemia compared to total thyroidectomy (TT) in PTC patients. Methods The data of the patients who were operated between 2015 and 2018 and diagnosed with PTC in the pre-operative or post-operative period were evaluated retrospectively, and two patient groups were formed. Group 1 included 19 patients who were diagnosed with PTC in the pathological examination after lobectomy was performed in the first operation, and after that CT was performed to the contralateral lobe. Among the patients who were diagnosed with pre-operative or post-operative PTC in the same period, 53 patients with characteristics similar to the 1st group in terms of age and gender were selected for Group 2. Biochemical parameters related to calcium metabolism in the pre-operative and post-operative periods, parathyroid autotransplantation and unintentional parathyroid gland removal, post-operative hypocalcemia, and treatment rates were compared between the two groups. Results There were 19 patients (13 F and 6 M) with a mean age of 48.3±12.1 years and 53 patients with a mean age of 46.3±9 (40 F and 13 M) in Groups 1 and 2, respectively, and there was no significant difference between the groups in terms of age and gender. There was no significant difference in terms of pre-operative parathormone (PTH), phosphorus (P), magnesium (Mg), Vitamin D deficiency rate, parathyroid autotransplantation, and presence of parathyroid gland in thyroid specimen. Pre-operative calcium (Ca) value was 9.33±0.46 in Group 1 and lower than Group 2 (9.65±0.41) (p=0.012). There was no significant difference between the groups in terms of post-operative day 0 Ca, P, Mg, and PTH and post-operative day 1 Ca, Mg, and PTH. Post-operative day 1 P level was significantly lower in Group 1 (2.86±0.72) compared to Group 2 (3.6±0.83). Post-operative hypocalcemia rates were 21.1% and 30.2% in Groups 1 and 2, respectively, and the difference was not significant (p=0.558). In both groups, hypocalcemia was transient and permanent hypoparathyroidism was not detected. Parathyroid autotransplantation rates (10.5% vs. 3.8%; p=0.283) and the rate of unintentionally removed parathyroid gland (0 vs. 15.1; p=0.185) were similar in Groups 1 and 2, respectively. Ca and active Vitamin D administration rates in the post-operative period were similar in Group 1 and Group 2 (10.5% vs. 22.6%; respectively), and there was no significant difference between the groups in terms of receiving treatment (p=0.327). Conclusion CT can be necessary in some patients with post-operative diagnose of PTC. CT can be performed without increased risk of hypocalcemia compared to TT.

Abstract
The approach utilized a systematic review of the medical literature executed with specifically designed criteria that focused on the etiologies and pathogenesis of hypoparathyroidism. Enhanced attention by endocrine surgeons to new knowledge about parathyroid gland viability are reviewed along with the role of intraoperative parathyroid hormone (ioPTH) monitoring during and after neck surgery. Nonsurgical etiologies account for a significant proportion of cases of hypoparathyroidism (~25%), and among them, genetic etiologies are key. Given the pervasive nature of PTH deficiency across multiple organ systems, a detailed review of the skeletal, renal, neuromuscular, and ocular complications is provided. The burden of illness on affected patients and their caregivers contributes to reduced quality of life and social costs for this chronic endocrinopathy. © 2022 The Authors.

Assessment of diagnostic capacity and decision-making based on the 2015 American Thyroid Association ultrasound classification system. World J Methodol 2022; 12:148-163. [PMID: 35721246 PMCID: PMC9157633 DOI: 10.5662/wjm.v12.i3.148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Revised: 02/27/2022] [Accepted: 04/24/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND This study evaluates the American Thyroid Association (ATA) ultrasound (US) classification system for the initial assessment of thyroid nodules to determine if it indeed facilitates clinical decision-making.
AIM To perform a systematic review and meta-analysis of the diagnostic value of the ATA US classification system for the initial assessment of thyroid nodules.
METHODS In accordance with the PRISMA statement for diagnostic test accuracy, we selected articles that evaluated the 2015 ATA US pattern guidelines using a diagnostic gold standard. We analyzed these cases using traditional diagnostic parameters, as well as the threshold approach to clinical decision-making and decision curve analysis.
RESULTS We reviewed 13 articles with 8445 thyroid nodules, which were classified according to 2015 ATA patterns. Of these, 46.62% were malignant. No cancer was found in any of the ATA benign pattern nodules. The Bayesian analysis post-test probability for cancer in each classification was: (1) Very-low suspicion, 0.85%; (2) Low, 2.6%; (3) Intermediate, 6.7%; and (4) High, 40.9%. The net benefit (NB), expressed as avoided interventions, indicated that the highest capacity to avoid unnecessary fine needle aspiration biopsy (FNAB) in the patterns that we studied was 42, 31, 35, and 43 of every 100 FNABs. The NB calculation for a probability threshold of 11% for each of the ATA suspicion patterns studied is less than that of performing FNAB on all nodules.
CONCLUSION These three types of analysis have shown that only the ATA high-suspicion diagnostic pattern is clinically useful, in which case, FNAB should be performed. However, the curve decision analysis has demonstrated that using the ATA US risk patterns to decide which patients need FNAB does not provide a greater benefit than performing FNAB on all thyroid nodules. Therefore, it is likely that a better way to approach the assessment of thyroid nodules would be to perform FNAB on all non-cystic nodules, as the present analysis has shown the ATA risk patterns do not provide an adequate clinical decision-making framework.

Abstract
BACKGROUND Total laryngectomy (TL) with thyroidectomy can pose significant risks to parathyroid function, and variance in rates of post-operative hypocalcemia (POH) based on extent of thyroidectomy have not been previously reported. Our objective is to identify the rates of hypocalcemia and hypoparathyroidism in TL+/-thyroidectomy and compare this to matched thyroidectomy alone cohorts. METHODS Multi-institutional retrospective chart review of patients treated surgically for laryngeal cancer with TL or benign/malignant thyroid disease with thyroidectomy at regional tertiary care centers in New Orleans and Baton Rouge, Louisiana from 2016 to 2019. Cases were evaluated for post-operative and post-discharge calcium and parathyroid hormone levels, post-operative and long-term calcium supplementation, and intraoperative parathyroid identification and management. RESULTS 101 TL and 319 thyroidectomy patients' charts were reviewed. Regression analysis revealed increased odds of hypocalcemia and hypoparathyroidism in TL + TT versus TT alone (OR 10.7, OR 16.5, p < 0.001, respectively). TL + HT versus HT alone had increased odds of hypoparathyroidism (OR 1.6, p < 0.001). TL with any thyroidectomy compared to TL alone demonstrated both increased odds of hypocalcemia and hypoparathyroidism (OR 4.4 p = 0.009, and OR 4.5 p = 0.05). Odds of requiring long-term calcium supplementation were significantly increased with the addition of thyroidectomy across all groups. TL + TT was 8 times as likely (p = 0.002) and TL + HT was 5.3 times as likely (p = 0.001) to require long-term calcium supplementation compared to TL alone. CONCLUSIONS Thyroidectomy combined with TL demonstrates marked increased risk of parathyroid dysfunction and resultant POH. Despite improved visualization of soft tissue anatomy with TL, risk of parathyroid injury in these settings requires special attention to extent of parathyroid dissection and potential devascularization to reduce long-term sequelae of hyperparathyroidism. Therefore, post-operative calcium monitoring after TL is necessary and should resemble the long-standing stringent protocols that already exist for monitoring in thyroidectomy populations.

Abstract
Objective Incidental parathyroidectomy is a relatively common occurrence in thyroid surgery, which may lead to hypoparathyroidism and postoperative hypocalcemia, but it is not well studied in children. The objectives of this study were to determine the rate of incidental parathyroidectomy, identify potential risk factors, and investigate postoperative complications in children undergoing thyroidectomy. Study Design Retrospective cohort study. Setting Patients who underwent thyroidectomy over a 10-year period at a tertiary children’s hospital. Methods Pathology reports were reviewed to determine incidental parathyroid gland tissue. Additional data collected included patient demographics, type of procedure, underlying thyroid pathology, as well as immediate and long-term postoperative clinical outcomes. Results Of 209 patients, 65 (31%) had incidental parathyroidectomy. Several variables were associated with incidental parathyroidectomy on univariable analysis. However, in the final multivariable model, only thyroidectomy with lymph node dissection was associated with increased odds of having incidental parathyroidectomy (odds ratio, 3.3; P = .04; 95% CI, 1.1-9.8). After a median follow up of 1 year, a significantly higher percentage of patients with incidental parathyroidectomy had evidence of long-term hypoparathyroidism (9/62 [15%] vs 3/144 [2%], P = .001). Conclusion Incidental parathyroidectomy was relatively common in our pediatric thyroidectomy population, which may be a result of several anatomic, clinical, and surgeon-related factors. Close attention to parathyroid preservation with meticulous surgical technique is the most practical method of preventing long-term hypoparathyroidism and hypocalcemia.

Abstract
BACKGROUND The transient acute hypocalcemia (HypoCa) is the most prevalent complication after total thyroidectomy, detected primarily by subnormal intact parathyroid hormone (iPTH) and calcium levels. However, the need for calcium supplementation is ambiguous in patients who exhibit low iPTH with normal calcium levels. The aim of this study was to evaluate complementary predictors of HypoCa in this scenario. METHODS A retrospective cohort study with of 1597 consecutive patients undergoing total thyroidectomy, with or without neck dissection, from January 2014 to December 2018 at a single institution. Patients with an iPTH <12 pg/mL and a total calcium level ≥8 mg/dL in the first 8 h after surgery were included. RESULTS 1597 patients identified with low postoperative iPTH without overt calcium deficiency was diagnosed. The transient HypoCa in that specific subgroup was 509 (31.9%). Multivariate analysis indicated that HYPOCA was associated with bilateral level VI neck dissection and pre- to postoperative calcium reduction >38 pg/mL. To better illustrate the model, we plotted a nomogram with the variables selected for the final model. CONCLUSION Total thyroidectomy patients who exhibit low postoperative iPTH levels without overt calcium deficiency should be considered for calcium replacement therapy when they a marked drop in iPTH postoperatively and underwent bilateral level VI neck dissection.

Abstract
Aim This systematic review and meta-analysis evaluates surgical outcome and safety results of conventional (OT) versus endoscopic transaxillary gasless thyroidectomies (ET). Material and methods A systematic literature search was performed. The weighted mean differences or the odd ratios with corresponding 95% CIs were examined for surgical outcomes and complications. The results were analysed using fixed- or random-effects models. The heterogeneity was checked by the Cochran Q test and the extent of inconsistency was evaluated by the I2 statistic. Results Ten studies and 1597 patients were included. All studies found that ET required longer operative time. Postoperative pain was significantly lower after ET on day 1 and day 7. No statistical difference was found in complication rates. Conclusions ET has disadvantages such as longer surgery time, but it is a feasible and safe procedure with lower postoperative pain and comparable complication rates to OT. However, good quality prospective randomised studies are necessary to draw firmer conclusions.

Abstract
Aim In this study, we aimed to investigate the effects of Ultrasonic Coagulation (UC), Bipolar Energy Sealing System (BESS), Intra Operative Nerve Monitoring (IONM) and surgical experience on the complications of thyroid surgery. Method The data of 1627 patients who underwent thyroid surgery for various indications in our department between 2009 and 2018 were analyzed retrospectively and the effects of different technological devices on complications were investigated. Results Transient recurrent laryngeal nerve (RLN) palsy was higher between 2009 and 2013, when IONM was not in routine use (p=0.029). There were no significant differences between two energy devices (UC and BESS) in terms of transient or permanent RLN palsy, bleeding, and transient or permanent hypocalcemia. Multivariate analysis showed that young age (0.006), female gender (0.016), surgery type (p<0.001), and lateral neck dissection (p=0.026) are independent risk factors for transient hypocalcemia. Conclusion The results indicate that there is no superior hemostatic device. IONM and specific branching decrease transient RLN palsy. Female gender, young age, completion thyroidectomy, and lateral neck dissection were independent risk factors for the development of transient hypocalcemia.

Risk Factors for Low Levels of Parathyroid Hormone after Surgery for Thyroid Cancer: A Single Center Study. J Clin Med 2021; 10:jcm10184113.

Abstract
Background: Thyroidectomy is the definitive treatment for most patients with thyroid cancer. Hypoparathyroidism is the most frequent complication of thyroidectomy, and its pathogenesis is multifactorial. The aim of this study is to evaluate the patient- and surgical-related risk factors for hypoparathyroidism after surgery for thyroid cancer. Methods: In this retrospective study, patients referred to surgery for thyroid cancer from 2016 to 2019 were enrolled. Preoperative serum calcium and parathyroid hormone (PTH) and postoperative 24 h PTH and calcium levels were evaluated. Demographic data, type of surgery, incidence of hypoparathyroidism and hypocalcemia were recorded for all the patients. Patients were divided into two groups based on post-operative PTH levels (≤12 and >12 pg/mL). Results: A total of 189 patients were enrolled in this study. There were 146 women (87.3%) and 43 men (22.7%), with a mean age of 51.3 years. A total of 79 patients (41.7%) underwent a neck dissection. A total of 59 patients (31.1%) had a postoperative PTH level < 12 pg/mL. Female sex, neck dissection, the yield of lymph node dissection and incidental parathyroidectomy were significantly associated with postoperative hypoparathyroidism. Incidental parathyroidectomy was reported in 44 (23.2%) patients and was correlated with younger age (<40 years) and neck dissection. There was no difference in the rate of post-operative hypocalcemia between patients with incidental parathyroidectomy and those without. Conclusions: Young patients undergoing neck dissection and with incidental parathyroidectomy have the highest risk of postoperative hypoparathyroidism after surgery for thyroid cancer. However, a large proportion of patients without incidental parathyroidectomy may have temporary hypocalcemia, suggesting that impaired blood supply of parathyroid glands during their identification and dissection may play a relevant role.

Abstract
Hypoparathyroidism is a rare disorder characterized by the absent or inappropriately decreased serum parathyroid hormone in the parathyroid glands, which is accompanied by impaired calcium-phosphorus metabolism.The main etiology of hypoparathyroidism remains damage or removal of the parathyroid glands during neck surgery. In view of the incidence of thyroid cancer, primary hyperparathyroidism and other pathologies of the neck organs, which radical treatment can lead to the parathyroid gland impairment, an increased number of patients with hypoparathyroidism is expected. Autoimmune hypoparathyroidism is the second most common form of the disease, usually occurring as part of type 1 autoimmune polyglandular syndrome. Autoimmune hypoparathyroidism usually occurs in childhood and is characterized by a severe course of the disease, especially in the case of concomitant malabsorption syndrome.Chronic hypoparathyroidism of any etiology requires lifelong multicomponent therapy, as well as careful monitoring and an individual approach to choose the optimal treatment strategy. In the absence of adequate follow-up, the risks of long-term complications significantly increase, particularly in the renal, cardiovascular systems; in the soft tissues and in the brain, it could lead to visual disturbances; pathology of the musculoskeletal system with a decreased bone remodeling and a potential risk of fractures, as well as to the neurocognitive disorders and an impaired health-related quality of life.Timely diagnosis, rational medical therapy and management strategy may reduce the risks of short-term and long-term complications, frequency of hospitalizations and disability of patients, as well as improve the prognosis.This review covers the main issues of Russian guidelines for the management of chronic hypoparathyroidism, approved in 2021, including laboratory and instrumental evaluation, treatment approaches and follow-up. This guidelines also include the recommendations for special groups of patients: with acute hypocalcemia, hypoparathyroidism during pregnancy.

Abstract
BACKGROUND Thyroidectomy is one of the common endocrinological surgeries for the treatment of thyroid disorders. Hypocalcemia is the potential complication after thyroidectomy, where is persistency can lead to serious systemic effects. The aim of this study is to evaluate the incidence of hypocalcemia in thyroidectomy patients. METHODS In this cross-sectional study, patients referred to (XXX) for thyroidectomy from 2019 to 2020 were enrolled. Preoperative serum calcium and postoperative 24- and 48-h calcium levels were evaluated in these patients. Demographic data (sex and gender), calcium levels, type of thyroidectomy and duration of surgery was recorded for all the patients. SPSS v22 was used for statistical analysis. P < 0.05 was considered as statistically significant. RESULTS Of 143 patients included in the study, the mean age was 49.7 ± 10.9 years and 61.5% were females and 38.5% were males. 49% patients had hypocalcemia in the first 24 hours after surgery and 63.6% following 48 hours of the surgery. The difference in calcium levels at three intervals were statistically significant, p = 0.001. The incidence of hypocalcemia was significantly more in women at 48 postoperative hours, p = 0.025. The age and duration of surgery was not significantly correlated with hypocalcemia, p > 0.05, whereas, patients who underwent total thyroidectomy had greater incidence of hypocalcemia 24 hours after the surgery, p = 0.021. CONCLUSIONS The incidence of hypocalcemia is greater in total thyroidectomy and female patients. Our study did not report significant correlation between duration of the surgery and age of the patients.

Abstract
Objective A meta-analysis to investigate the risk factors for postoperative hypocalcaemia after thyroidectomy in adult patients. Methods A systematic search of publications in the electronic databases (PubMed®, The Cochrane Library, Web of Science, OVID and Embase®) from inception to June 2020 was conducted. Screening of titles, abstracts and full texts and data extraction were independently performed by two authors. The OR was selected as the pooled estimate. Results The analysis included 23 studies. Twelve significant risk factors for postoperative hypocalcaemia were identified: hypoparathyroidism, OR 5.58; total thyroidectomy, OR 3.59; hypomagnesaemia, OR 2.85; preoperative vitamin D deficiency, OR 2.32; female sex, OR 1.49; thyroid malignancy, OR 1.85; thyroiditis, OR 1.48; substernal multinodular goitres, OR 1.70; parathyroidectomy, OR 1.58; central compartment neck dissection, OR 1.17; modified radical neck dissection, OR 1.57; and central neck dissection, OR 1.54. Conclusions This meta-analysis provides moderate-to-high quality evidence that the 12 risk factors were predictive of postoperative hypocalcaemia, which should be monitored closely before thyroidectomy.

Abstract
BACKGROUND Preoperative administration of a saturated solution of potassium iodide (SSKI) is recommended in the guidelines for the management of hyperthyroidism due to Graves' disease. Studies addressing its effect on complications after thyroidectomy are inconclusive. METHODS Retrospective multicenter Propensity Score study of patients undergoing total thyroidectomy for Graves' disease, from January 2013 to September 2019 in two tertiary centers in Madrid, Spain. Patients were given SSKI prior to surgery or not according to surgeons' preferences. Electronic clinical records were reviewed searching: baseline characteristics surgical variables, pathological findings, and postoperative complications. RESULTS Ninety patients were analyzed: 44 received SSKI and 46 were not given SSKI. No significant differences were found in the main postoperative complications with or without SSKI: transient hypoparathyroidism (40.9% vs. 50%), permanent hypoparathyroidism (6.8% vs. 13%), transient recurrent laryngeal nerve (RLN) palsy (2.3% vs. 8.7%), definitive RLN palsy (2.3% vs. 2.2%), or cervical hematoma (2.3% vs. 4.3%). CONCLUSION Preoperative administration of SSKI had no impact on postoperative complications after thyroidectomy for Graves' disease.

Abstract
CONTEXT Post-operative clinical and biochemical hypocalcemia is a common complication of thyroid surgery and the correlation with incidental parathyroidectomy (IP) remains controversial. OBJECTIVE To evaluate the incidence of IP during TT, its correlation to early post-surgery hypocalcemia, and its potential risk factors. PATIENTS AND METHODS 77 consecutive patients submitted to thyroid surgery between January 2018 and December 2019. Demographic, clinical, biochemical, surgical and histopathological factors were assessed. Statistical multivariate analysis was performed to identify the risk of IP. RESULTS IP was evident in 22 (28.5%) patients who underwent TT, TT with lymph node dissection of the central compartment (CLND) and reoperation for previous hemithyroidectomy with CLND. Early symptomatic hypocalcemia 24 hours after TT was demonstrated in 12/22 (54.5%) patients, with PTH value of <14pg/mL in 7/12 (58.3%) patients, and in 6 of these 7 patients (85.7%) the PTH value was <6.3pg/mL. In 5/22 (22.7%) patients the IP was associated with biochemical hypocalcemia <8.4mg/dL, and in 5/22 (22.7%) patients anatomical damage was not associated with a reduction in plasma calcium levels. The severity of early post-op hypocalcemia was not correlated with the number of parathyroid glands left in situ. The multivariate analysis did not show statistically significant values between the clinical-pathological variables and increased risk of IP. CONCLUSIONS No IP clinical-pathological risk factors have been identified during thyroid surgery. In all cases of TT, with or without CLND, the meticulous identification of the parathyroid glands, whose incidental removal is frequently associated with clinical and biochemical hypocalcemia, is recommended.

Abstract
Currently, thyroid surgery is the most common and safe operation worldwide. However, thyroidectomy is still not free from the risks of complications and death due to the anatomical structure and physiological function particularity of the thyroid gland. Postoperative complications affect the life quality and life safety of patients after surgery. The common complications include hypoparathyroidism (HP), recurrent laryngeal nerve (RLN) injury, injury to the external branch of the superior laryngeal nerve (EBSLN), postoperative bleeding (PB), thoracic duct injury, laryngeal edema, tracheospasm, tracheal injury, and esophageal injury. A severe complication, such as dyspnea, asphyxia, or thyroid crisis, might cause the death of the patient. Therefore, every thyroid surgeon's responsibility is to remain alert and aware of the occurrence of various intraoperative and postoperative complications and exercise effective prevention and treatment. This is closely related to the advancement in thyroid disease research, the increase in local anatomy knowledge, the standardization of surgical approaches, the improvement in operating skills, the application of new technologies, and the emphasis on specialty training. In addition, many complications that effect patients are much better tolerated if the patient has appropriate expectations of what the complications are and how to treat them. Open communication between surgeon and patient optimizes the potential negative effects that complications may have on patients' quality of life. This paper discusses the prevention, recognition and therapy of intraoperative and postoperative complications in thyroid surgery.

Abstract
Postoperative parathyroid failure is the commonest adverse effect of total thyroidectomy, which is a widely used surgical procedure to treat both benign and malignant thyroid disorders. The present review focuses on the scientific gap and lack of data regarding the time period elapsed between the immediate postoperative period, when hypocalcemia is usually detected by the surgeon, and permanent hypoparathyroidism often seen by an endocrinologist months or years later. Parathyroid failure after thyroidectomy results from a combination of trauma, devascularization, inadvertent resection, and/or autotransplantation, all resulting in an early drop of iPTH (intact parathyroid hormone) requiring replacement therapy with calcium and calcitriol. There is very little or no role for other factors such as vitamin D deficiency, calcitonin, or magnesium. Recovery of the parathyroid function is a dynamic process evolving over months and cannot be predicted on the basis of early serum calcium and iPTH measurements; it depends on the number of parathyroid glands remaining in situ (PGRIS)—not autotransplanted nor inadvertently excised—and on early administration of full-dose replacement therapy to avoid hypocalcemia during the first days/weeks after thyroidectomy.

Abstract
OBJECTIVE This study aims to determine the frequency of incidental parathyroidectomy (IP), to reveal the risk factors and to present the clinical importance of IP through the experiences of our clinic. MATERIALS AND METHODS Patients undergoing thyroid surgery between June 2016 and May 2019 were reviewed retrospectively. Along with demographic data, surgery reports, pathology results and postoperative follow-up data were examined. Factors assumed to be associated with IP and postoperative hypocalcemia were compared between the IP group and the non-IP group. RESULTS A total of 633 patients with a mean age of 48 ± 13 years were included in this study. IP was detected in 138 (21.8%) patients and parathyroid glands were localized 29.72% intrathyroidal. Postoperative hypocalcemia in the IP group was approximately 2-fold higher than the no-IP group (%15.94 to %7.27), (p < .001). Gender (p = .014), body mass index (p = .021), both preoperative and postoperative diagnosis of malignancy (p < .001) and performing central neck dissection (CND) (p < .001) were significantly associated with IP in univariate analysis. However, multivariate analysis demonstrated that CND was independently associated with IP (OR = 0.301, 95% Cl: 0.161-0.562, p < .001). CONCLUSION This study reveals that IP increases the frequency of postoperative temporary and permanent hypocalcemia in patients undergoing thyroid surgery, and CND is the only independent risk factor for IP. Highlights of the study This study reveals that central neck dissection is the most important and only independent risk factor for incidental parathyroidectomy in patients undergoing thyroid surgery. According to our analysis, both temporary and permanent hypocalcemia, which occurs in the postoperative period, are associated with incidental parathyroidectomy.

Abstract
BACKGROUND Although higher thyroidectomy volume has been linked with lower complication rates, its association with incidental parathyroidectomy remains less studied. The volume relationship is even less clear for central neck dissection, where individual parathyroid glands are at greater risk. METHODS Patients undergoing thyroidectomy with or without central neck dissection were evaluated for incidental parathyroidectomy, hypoparathyroidism, and hypocalcemia. Univariate and multivariable analyses were performed using binary logistic regression. RESULTS Overall, 1,114 thyroidectomies and 396 concurrent central neck dissections were performed across 7 surgeons. Incidental parathyroidectomy occurred in 22.4% of surgeries (range, 16.9%-43.6%), affecting 7.1% of parathyroids at risk (range, 5.8%-14.5%). When stratified by surgeon, lower incidental parathyroidectomy rates were associated with higher thyroidectomy volumes (R2 = 0.77, P = .008) and higher central neck dissection volumes (R2 = 0.93, P < .001). On multivariable analysis, low-volume surgeon (odds ratio 2.94, 95% confidence interval 2.06-4.19, P < .001), extrathyroidal extension (odds ratio 3.13, 95% confidence interval 1.24-7.87, P = .016), prophylactic central neck dissection (odds ratio 2.68, 95% confidence interval 1.65-4.35, P <.001), and therapeutic central neck dissection (odds ratio 4.44, 95% confidence interval 1.98-9.96, P < .001) were the most significant factors associated with incidental parathyroidectomy. In addition, incidental parathyroidectomy was associated with a higher likelihood of temporary hypoparathyroidism (odds ratio 2.79, 95% confidence interval 1.45-5.38, P = .002) and permanent hypoparathyroidism (odds ratio 4.62, 95% confidence interval 1.41-5.96, P = .025), but not permanent hypocalcemia (odds ratio 1.27, 95% confidence interval 0.48-3.35, P = .63). Higher lymph node yield in central neck dissection was not associated with higher incidental parathyroidectomy rates (odds ratio 1.13, 95% confidence interval 0.85-8.81, P = .82). CONCLUSION Higher surgical volume conferred a lower rate of incidental parathyroidectomy. Nonetheless, greater lymph node yield in central neck dissections did not result in greater parathyroid-related morbidity. Such findings support the value of leveraging surgical volume to both optimize oncologic resection and minimize complication rates.

Abstract
Background Thyroid surgery is one of the most commonly performed procedures internationally. There were no studies conducted in Tabuk, Saudi Arabia, on post-thyroidectomy complications and their risk factors. Objective The aim of this study was to assess post-thyroidectomy complications and determine the risk factors of such complications. Methods This retrospective study included all cases that underwent thyroidectomy at King Salman Armed Forces Hospital, Tabuk, Saudi Arabia, from January 2012 to December 2017. Patients with preoperative hypoparathyroidism, chronic kidney disease, or history of dysphonia were excluded. Data were collected from medical records. Results The study showed 182 patients who underwent thyroidectomy operation between January 2012 and December 2017. Temporary hypocalcemia was developed in 116 patients (63.7%) while it persisted in three (1.6%). Change of voice was reported in five patients (2.7%) while two (1.1%) lost a high-pitched voice. Seroma, hematoma, and tracheal injury were documented in 1.6%, 1.1%, and 0.5%, respectively. Multivariate analysis showed that total thyroidectomy was the most significant (four times) risk factor for the development of hypocalcemia as compared to other surgical procedures. Conclusion Hypocalcemia was the most frequent post-thyroidectomy complication, whereas voice changes, seroma, hematoma, and tracheal injury are rare complications. Additionally, total thyroidectomy has the highest risk of postoperative hypocalcemia.

Abstract
Background Incidental excision of parathyroid glands is a common event during thyroid surgery and in spite the divergent results that can be obtained from the literature about its clinical significance, all efforts must be used to their preservation. Due to the autofluorescence emitted by parathyroid glands, authors began to use a custom device to inspect thyroidectomy specimens for incidentally removed parathyroid tissue; the results of using this device are presented in this manuscript. Methods Specimens of 40 consecutive thyroid surgeries were inspected. Localization of suspect high-fluorescence spots were recorded for confirmation with a pathological exam. Determinations of calcium and parathyroid hormone (PTH) were completed prior to surgery and at 24 hours and 15 days after the operation. Results Patient age ranged from 36 to 83 years and were predominantly female (82.5%). Calcium values at 24 hours post-operation varied between 7.1 and 9.5. The PTH values ranged between 3 and 77. Thirteen patients (32.5%) presented with biochemical hypocalcemia at 24 hours. At 15 days after the operation, only one patient presented with a calcium value below 8 (PTH: 10.9) with complete normalization 6 months after the surgery. Pathological examination identified eight parathyroid fragments in seven patients. There was no correlation between the presence of parathyroid tissue in the specimen and post-operative hypocalcemia (P=0.254). Eight suspicious areas of augmented fluorescence where detected; seven were coincident with the pathological examination and one was a false positive. One intrathyroidal gland was not identified, resulting a sensitivity of 87.5% and specificity 96.2%. Conclusions Although no correlation between incidental parathyroidectomy and hypocalcemia was demonstrated, autofluorescence may be a useful tool for in-table identification of incidentally-removed glands.

Abstract
BACKGROUND Incidental parathyroidectomy during total thyroidectomy may occur even in the most experienced hands. This study aims to assess the incidence, risk factors, and impact of incidental parathyroidectomy on this very targeted group of patients. METHODS Three hundred and four consecutive cases undergoing total thyroidectomy in a tertiary referral center were prospectively studied. Based on the histopathology report, incidental parathyroidectomy was assessed in relation to postoperative transient/permanent hypocalcemia. Demographic, clinical, and histological data were analyzed. RESULTS The overall incidence of unintentional removal of parathyroid glands during total thyroidectomy was 35.5 %. Indicators were the postoperative hypocalcemia, the percent change of parathormone serum levels, and the presence of lymph nodes in the histopathology report. Patients with incidental parathyroidectomy exhibited a higher incidence of transient hypocalcemia and hypoparathyroidism postoperatively. CONCLUSIONS Incidental parathyroidectomy is associated with transient hypocalcemia after total thyroidectomy. Even single parathyroid in the histopathology specimen may be sufficient for influencing postoperative PTH levels and calcium. Every effort should be made by surgeons to identify and protect all parathyroid glands successfully. HIPPOKRATIA 2020, 24(2): 72-76.

Abstract
Background: Incidental parathyroidectomy with subsequent hypoparathyroidism and postoperative hypocalcemia is thought to be one of the common complications of thyroidectomy. Current literature reports wide discrepancy in incidence and risk factors. Objectives: The aim of our study was to evaluate the incidence and risk factors of incidental parathyroidectomy in thyroid surgery. Methods: A retrospective study included 270 patients who had thyroid surgery that was performed over two years from January 2017 to December 2018 in two tertiary care hospitals. Preoperative and postoperative records were assessed. Factors such as gender, diagnosis, type of surgery, and usage of surgical loupes during the procedure were evaluated and were compared to find the association with incidental parathyroidectomy in thyroid surgery. Results: Incidental parathyroidectomy was noticed in 62 (23%) surgical specimens during histopathologic examination. There was no significant association between incidental parathyroidectomy and sex of patient, use of surgical loupes, pathology of thyroid disease, or neck dissection. Conclusion: Although the risk of incidental parathyroidectomy is inevitable, careful dissection and meticulous intraoperative identification of parathyroid gland during thyroidectomy can reduce the incidence of incidental parathyroidectomy, thereby minimizing the risk of postoperative hypoparathyroidism and hypocalcemia.

Abstract
Background: The aim of this study was to determine the incidence of incidental parathyroidectomy, the relationship between incidental parathyroidectomy and postoperative hypocalcemia, and risk factors for incidental parathyroidectomy in patients undergoing thyroid surgery. Methods: The study was conducted by analyzing the records of patients who underwent thyroid surgery in a tertiary university hospital between January 2012 and December 2017 retrospectively. The risk factors of postoperative hypocalcemia were determined by comparing postoperative Ca values with age, sex, preoperative Ca value, dominant nodule diameter, type of surgery, and histopathological examination of the thyroidectomy material. According to the final pathology results, the patients were divided into two groups - the ones with and without incidental parathyroidectomy. The risk factors for incidental parathyroidectomy were determined by comparing the two groups in terms of age, sex, dominant nodule diameter, type of surgery, and histopathological results (malign/benign). Results: When the risk factors of postoperative hypocalcemia were examined, female gender, age <28.5 years old, low level of preoperative mean Ca value, and total thyroidectomy were found to be critical risk factors (p<0.05). When the risk factors of incidental parathyroidectomy were examined, total thyroidectomy and thyroid malignancy were found to be important risk factors (p<0.05). Conclusion: Female gender, age<28.5 years old, low level of preoperative Ca value, and total thyroidectomy were associated with postoperative hypocalcemia, but no relationship was found between incidental parathyroidectomy and postoperative hypocalcemia.
