RESUMO
BACKGROUND: Lugol solution is often administered to patients with Graves' disease before surgery. The aim is to reduce thyroid vascularization and surgical morbidity, but its real effectiveness remains controversial. The present study was designed to evaluate the effects of preoperative Lugol solution on thyroid vascularization and surgical morbidity in patients with Graves' disease undergoing total thyroidectomy. METHODS: Fifty-six patients undergoing total thyroidectomy for Graves' disease were randomly assigned to receive 7 days of Lugol treatment (Lugol+ group, 29) or no Lugol treatment (LS- group, 27) before surgery in this single-centre and single-blinded trial. Preoperative hormone and colour Doppler ultrasonographic data for assessing thyroid vascularization were collected 8 days before surgery (T0) and on the day of surgery (T1). The primary outcome was intraoperative and postoperative blood loss. Secondary outcomes included duration of surgery, thyroid function, morbidity, vascularization, and microvessel density at final pathology. RESULTS: No differences in demographic, preoperative hormone or ultrasonographic data were found between LS+ and LS- groups at T0. At T1, free tri-iodothyronine (FT3) and free thyroxine (FT4) levels were significantly reduced compared with T0 values in the LS+ group, whereas no such variation was observed in the LS- group. No differences between T0 and T1 were found for ultrasonographic vascularization in either group, nor did the histological findings differ. There were no significant differences between the LS+ and LS- groups concerning intraoperative/postoperative blood loss (median 80.5 versus 94 ml respectively), duration of surgery (75 min in both groups) or postoperative morbidity. CONCLUSION: Lugol solution significantly reduces FT3 and FT4 levels in patients undergoing surgery for Graves' disease, but does not decrease intraoperative/postoperative blood loss, thyroid vascularization, duration of surgery or postoperative morbidity.

INTRODUCTION: Total thyroidectomy (TTx) has been reported to be more challenging in patients with Graves' disease, especially in those who are hyperthyroid at the time of surgery. Our aim was to compare outcomes in patients undergoing TTx for Graves' disease compared to other thyroid diseases at a large academic institution with high-volume fellowship-trained endocrine surgeons. METHODS: In our retrospective analysis from December 2015 to May 2023, patients undergoing TTx for Graves' disease were compared to those undergoing TTx for all other indications excluding advanced malignancy (poorly differentiated thyroid cancer and concomitant neck dissections). Patient demographics, biochemical values, and postoperative outcomes were compared. A subgroup analysis was performed comparing hyperthyroid to euthyroid patients at the time of surgery. RESULTS: There were 589 patients who underwent TTx, of which 227 (38.5%) had Graves' disease compared to 362 (61.5%) without. Intraoperatively in Graves' patients, nerve monitoring was used more frequently (65.6% versus 57.1%; P = 0.04) and there was a higher rate of parathyroid autotransplantation (32.0% versus 14.4%; P < 0.01). Postoperatively, transient voice hoarseness occurred less frequently (4.8% versus 13.6%; P < 0.01) and there was no difference in temporary hypocalcemia rates or hematoma rates. In our subgroup analysis, 83 (36%) of Graves' patients were hyperthyroid (thyroid-stimulating hormone < 0.45 and free T4 > 1.64) at the time of surgery and there were no differences in postoperative complications compared to those who were euthyroid. CONCLUSIONS: At a high-volume endocrine surgery center, TTx for Graves' disease can be performed safely without significant differences in postoperative outcomes. Hyperthyroid patients demonstrated no differences in postoperative outcomes.

Thyroidectomy in Graves' disease can be challenging due to greater thyroid size and vascularity. While thyroid stimulating hormone receptor antibody (TRAb) level is associated with disease severity and thyroid vascularity, its impact on operative outcomes remains unclear. This study aimed to compare challenging factors for robotic thyroidectomy (RT) and open thyroidectomy (OT) in Graves' disease patients, including TRAb as a predictive factor for difficult thyroidectomy. This retrospective study included Graves' disease patients who underwent total thyroidectomy between September 2013 and January 2023. The clinical characteristics and operative outcomes were compared between patients who received OT and bilateral axillo-breast approach RT. Factors affecting operation time and estimated blood loss (EBL) were evaluated in both groups using regression analyses. A total of 85 patients received either OT (n = 48) or RT (n = 37). Median thyroid volumes in the OT and RT groups were 72.4 g and 57.6 g, respectively. Operation time was affected by thyroid volume in both groups. Additionally, higher thyroid hormone levels and bilateral central neck node dissection prolonged operation time in the RT group. EBL was marginally associated with thyroid volume in the OT group. However, in the RT group, TRAb level was independently associated with greater EBL (p = 0.04), while no significant association was found with thyroid volume. Predictive factors for difficult thyroidectomy differed by operation approaches. TRAb significantly predicted intraoperative bleeding in RT, while this association was absent in OT. Caution is warranted when performing RT on Graves' disease patients with high TRAb levels.

PURPOSE: This study aimed to investigate the relationship between Lugol iodine treatment in a rescue setting and surgical outcomes in Graves' disease patients. METHODS: The retrospective register-based cohort study included 813 patients who had undergone primary total thyroidectomy with a primary diagnosis of Graves' disease (ICD-code E05.0) at Karolinska University Hospital in Stockholm, Sweden, between January 2008 and December 2015. Of 813 patients, 33 (4.1%) were given Lugol iodine before surgery and the remaining, the non-Lugol group, did not. The study's primary outcomes were post-operative calcium treatment day 1, calcium and vitamin D supplements at discharge and follow-up. Secondary outcomes were laryngeal nerve damage and bleeding (defined as re-operation). RESULTS: Differences were found between the Lugol and non-Lugol groups in the treatment of calcium day 1 (45.5% vs 26.7%, p = 0.018), at discharge (36.4% vs. 16.2%, p = 0.002) and vitamin D supplements at discharge (36.4% vs. 19.1%, p = 0.015) as surrogate variables for hypocalcemia post-operatively. No differences could be seen at 4-6 weeks and six-months follow-up. There were no differences between the Lugol and non-Lugol groups in terms of operation time, laryngeal nerve damage, and bleeding. CONCLUSION: Patients in our cohort undergoing thyroidectomy due to Graves' disease pre-operatively treated with Lugol iodine as a rescue therapy had a higher risk of experiencing short term post-operative hypocalcemia.

INTRODUCTION: The transoral endoscopic thyroidectomy vestibular approach (TOETVA) is a safe alternative to thyroidectomy for thyroid goiter and provides the benefit of being scarless. However, the data on the use of TOETVA in patients with Graves disease are limited. This retrospective study compared the outcomes of Graves disease patients who underwent TOETVA versus those who underwent open thyroidectomy (OT). MATERIALS AND METHODS: Patients with Graves disease who received TOETVA or OT for bilateral total thyroidectomy between September 2017 and October 2022 were included. Patient demographics and surgical outcomes, including operation time, blood loss, length of stay, and complications, were compared. RESULTS: There were 15 patients in each group. The mean age in the TOETVA group was 35.80±8.13 years, which was significantly younger than that in the OT group, which was 51.53±14.22 years. Females predominated in both groups. The other demographic characteristics were similar in both groups. The operation time and intraoperative blood loss were also comparable. The postoperative stay and complications, including hypoparathyroidism, recurrent laryngeal nerve injury, surgical site infection, postoperative hemorrhage, and recurrence of hyperthyroidism, were not different between the 2 groups. There were 11 patients in the TOETVA group and 10 in the OT group who had thyroglobulin levels <0.1 ng/dL, indicating the completeness of total thyroidectomy in the 2 groups. There was no conversion of TOETVA to an open procedure. CONCLUSIONS: For carefully selected Graves patients, TOETVA offers a safe, scarless, and feasible alternative to conventional open thyroidectomy.

INTRODUCTION: Decision-making regarding definitive therapy for Graves' disease requires effective patient-provider communication. We investigated whether patients with limited English proficiency have differences in thyroidectomy outcomes or perioperative management when compared to English proficient (EP) patients at a safety net hospital with high-volume endocrine surgery practice. METHODS: Retrospective study of patients who underwent thyroidectomy (2012-2021) for Graves' disease within a tertiary referral system. Demographics, preoperative factors, and postoperative outcomes were abstracted via chart review and compared between EP and limited English proficient (LEP) patients in univariate analyses. Odds of postoperative complications were assessed via multivariable logistic regression. Time metrics such as time from endocrinology consultation to surgery were compared via Kaplan-Meier analysis and adjusted Cox proportional regression models. RESULTS: Of 236 patients, 85 (36%) had LEP. Low and equivalent complication rates occurred across language groups (<1% permanent). LEP patients had similar odds of thyroidectomy-specific complications (odds ratio = 1.2; 95% confidence interval 0.6-2.4). Adjusted Cox proportional hazards ratios showed that LEP patients experienced significantly shorter time from endocrinology consultation to surgery compared to EP patients [hazard ratio = 0.7; 95% confidence interval 0.5-0.9]. CONCLUSIONS: Thyroidectomy-specific complication rate for patients with Graves' disease was low, and we detected no independent association between complications and English language proficiency. Non-English primary language was independently associated with reduced time from endocrinology consultation to surgery. This finding must be interpreted with nuance and is likely multifactorial. It may reflect a well-organized, efficient system for under-resourced patients, or it may derive from communication barriers that limit robust shared decision-making, thus accelerating time to surgery.

BACKGROUND: Graves disease is the most common cause of hyperthyroidism in the US. Treatment with antithyroid drugs and radioactive iodine is more commonly used than surgical management with total thyroidectomy (TTx). However, incidentally discovered thyroid cancer (TC) has been described on surgical pathology from patients who underwent surgical treatment of Graves disease, which would be missed with these other treatment strategies. We sought to determine the incidence rate of TC among patients with surgically treated Graves disease. STUDY DESIGN: We retrospectively reviewed patients with Graves disease who underwent TTx at a single institution from 2011 to 2023. Pathology reports were reviewed for TC. Patient demographics, preoperative laboratory and radiological evaluations, preoperative medical management, and surgical outcomes were compared between patients with and without incidental TC. RESULTS: There were 934 patients, of whom 60 (6.4%) patients had incidentally discovered TC on pathology. The majority (58.3%) of patients had papillary thyroid carcinoma, followed by 33.3% with papillary microcarcinoma. Preoperative ultrasound (US) was obtained in 564 (60.4%) of patients, with 44.3% with nodules, but only 34 (13.7%) of those with nodules had TC on final pathology. Preoperative fine needle aspiration was obtained in 15 patients with TC, and 8 patients (53.3%) were reported as benign lesions, which ultimately had TC on final pathology. There was no difference in sex, race or ethnicity, preoperative medical management, and postoperative outcomes between the 2 groups. CONCLUSIONS: Incidental TC was found on surgical pathology in 6.4% of patients undergoing TTx for Graves disease. Preoperative imaging with US and fine needle aspiration were often unreliable at predicting TC. The incidence of TC should not be underestimated when counseling patients on definitive management for Graves disease.

OBJECTIVE: Patients with Graves' disease often engage in shared decision-making to select an individualised treatment regimen from multiple options. Radioactive iodine (RAI) is one of the treatment choices for their condition, aims to improve quality of life and well-being. Likewise, dissatisfaction with treatment outcomes can result in decision regret. We employed validated questionnaires to assess the prospective quality of life, decision regret and relative factors involved in decision-making of patients with late hypothyroidism after RAI therapy. METHODS: A questionnaire survey was conducted among patients in hypothyroidism status for more than 1 year after RAI therapy. Disease-specific and generic QoL were assessed using the short form of thyroid-related patient-reported outcome (ThyPRO-39) questionnaire. Patient satisfaction regarding their decision to undergo RAI was assessed using the Decision Regret Scale (DRS) and patients were asked about the importance of relative factors in decision-making. RESULTS: Of 254 patients who responded to the survey, the mean age of patients was 45.3 years (range: 18-78 years) and the median time from RAI therapy to survey was 4 years (range: 1-30 years). Patients' median and mean DRS score were 34.4 and 38.8 (range: 0-100), respectively. A total of 100 (39.4%) patients express absent-to-mild regret (score: 0-25), 154 (60.6%) patients express moderate-to-severe regret (score: >25). The mean score of the absent-to-mild regret group were significantly higher than those of the moderate-to-severe regret group on most ThyPRO-39 scales. A statistically significant positive correlation was observed between DRS score and most ThyPRO-39 scale score. There was a significant positive association between higher DRS score and longer time intervals after RAI treatment, a brief duration of hyperthyroidism, and the significance of long-time outpatient follow-up. More decision regret was negatively associated Iodine-free diet, ineffectiveness of ATD, fear of surgery. CONCLUSION: Impairment of quality of life was positively correlated with decision regret in patients with late-hypothyroidism after radioiodine therapy. Patients with insufficient information support before decision-making are more likely to have higher decision regret after treatment. Our findings suggest that health providers should fully communicate with patients and provide information support in multiple dimensions during the shared-decision-making process.

BACKGROUND: The most frequent complication of total thyroidectomy remains hypocalcemia due to low postoperative levels of serum intact parathyroid hormone (iPTH). The purpose of this study was to investigate the role of decreased iPTH at the end of surgery in predicting hypocalcemia. In addition, we examined the percentage decrease of iPTH as potential indicator of hypocalcemia. METHODS: We retrospectively collected the data of patients who underwent total thyroidectomy for benign and malignant diseases at our institution between 2010 and 2022. The iPTH level was measured before and at the end of surgery, and serum calcium levels on the first postoperative day. Demographic, clinical, and biochemical characteristics of patients with low iPTH were compared with patients with normal iPTH levels using ANOVA for continuous variables and χ2-tests for categorical variables. Multivariable logistic regression analysis evaluated the association of iPTH at the end of surgery and the relative reduction of iPTH with postoperative hypocalcemia. RESULTS: The mean age of the 607 patients in this study was 55.6 years, and the female-to-male ratio was 5:1. Goiter was the most common indication for surgery (N = 382, 62.9%), followed by Graves' disease (N = 135, 22.2%). The mean preoperative iPTH was 49.0 pg/ml, while the mean postoperative iPTH was 29.3 pg/ml. A total of 197 patients (32.5%) had an iPTH level below normal, 77 patients (39%), had iPTH levels of 10-15.0 pg/ml and 120 patients (61%) of < 10.0 pg/ml at the end of surgery. Among all patients, 124 (20.4%) developed hypocalcemia on the first postoperative day. The mean percentage of decrease of iPTH was highest among patients with iPTH < 10 pg/ml (76.9%, p < 0.01); this group of patients had also the highest rate of postoperative hypocalcemia on day one (45.0% vs. 26.0% vs 12.2%, p < 0.01). CONCLUSIONS: Measurement of iPTH at the end of total thyroidectomy predicts patients who are at risk for postoperative hypocalcemia. The combination of low serum iPTH with a decrease in iPTH level of ≥ 50% may improve prediction of hypocalcemia compared to iPTH levels alone allowing for early calcium substitution in these patients at high risk of developing postoperative hypocalcemia.

BACKGROUND: This case report is of a patient with psychosis secondary to thyrotoxicosis that persisted and reemerged after definitive treatment of thyroidectomy, which is a unique occurrence in the literature. CASE PRESENTATION: This patient is a male between 30 and 35 years of age with a history of Graves Disease and no past psychiatric history who was admitted to the hospital due to psychosis secondary to thyrotoxicosis. The thyrotoxicosis was treated with surgical removal, but the psychotic symptoms persisted after surgery and normalization of standard thyroid functional measures. The symptoms were of sufficient significance for inpatient psychiatric hospitalization, a rare occurrence. Ultimately after an extended stay in the psychiatric unit, the patient's symptoms stabilized with a second-generation antipsychotic, and the patient was discharged from the psychiatric unit. CONCLUSION: This case is evidence that the link between psychosis and hyperthyroidism is still poorly understood due to the patient's psychotic symptoms persisting after the definitive treatment of thyroidectomy and the fact that it required anti-psychotic medications for normalization.

BACKGROUND: Outcomes of paediatric thyroid surgery have only been reported in smaller series or over long intervals. The aim of this multicentre study was to describe the recent outcomes of paediatric thyroid surgery in Germany and Austria. METHODS: Patients aged less than or equal to 18 years who underwent thyroid surgery and were prospectively documented in the StuDoQ|Thyroid registry between March 2017 and August 2022 were studied. RESULTS: In total, 604 patients from 90 institutions were included. The mean age was 15.4 years and 75 per cent of patients were female. The most frequent benign pathologies were nodular goitre (35.6 per cent), follicular adenoma (30.1 per cent), and Graves' disease (28.5 per cent). Among 126 thyroid malignancies, papillary thyroid carcinoma was diagnosed in 77.8 per cent of patients, follicular thyroid carcinoma was diagnosed in 10.3 per cent of patients, and medullary thyroid carcinoma was diagnosed in 8.7 per cent of patients. Lymph node metastases were found in 45.9 per cent of patients with papillary thyroid carcinoma and in 36.4 per cent of patients with medullary thyroid carcinoma. Vascular invasion was found in 62.9 per cent of patients with follicular thyroid carcinoma. The mean tumour diameters were 18, 42, and 13 mm in patients with papillary thyroid carcinoma, follicular thyroid carcinoma, and medullary thyroid carcinoma respectively. Early postoperative recurrent laryngeal nerve injury was seen in 27 of 556 patients (4.9 per cent) (22 of 617 (3.6 per cent) nerves at risk with intermittent intraoperative nerve monitoring and 5 of 237 (2.1 per cent) nerves at risk with continuous intraoperative nerve monitoring). Persistent recurrent laryngeal nerve injury was documented in 4 of 556 patients (0.7 per cent). Early postoperative hypoparathyroidism correlated with Graves' disease, thyroid carcinoma, and lymph node dissection. CONCLUSION: Papillary thyroid carcinoma and follicular thyroid carcinoma in children were often advanced at presentation. Persistent or recurrent lymph node metastases were mainly seen in papillary thyroid carcinoma. Overall survival was excellent, but longer follow-up is needed.

BACKGROUND: Multiple surgical specializations are involved in the operative management of pediatric thyroid disease, but current practice patterns remain unknown. The objective of this study was to examine current practice patterns in the operative management of pediatric thyroid disease, specifically comparing practices across different surgical specializations including pediatric surgery, pediatric otolaryngology, general surgery, adult otolaryngology, and endocrine-focused general surgery. METHODS: Children 0-18 years-old undergoing thyroid surgery from 2015 to 2019 were identified using the Healthcare Cost and Utilization Project State Inpatient Databases and State Ambulatory Surgery and Services Databases across 6 states. Surgeon specialization was determined for all included surgeons. Patient and hospital characteristics were compared across surgical specializations. Clinical outcomes including hypocalcemia/hypoparathyroidism, recurrent laryngeal nerve injury, hematoma, and wound infection were assessed. RESULTS: A total of 1241 pediatric thyroidectomies performed by 363 surgeons were included. Procedures were most frequently performed by pediatric surgeons (34.9%). Only 7.2% of procedures were performed by adult general surgeons. There were statistically significant differences in patient age, sociodemographics, surgical indications, and type of procedure performed between specializations (p < 0.05). Endocrine-focused general surgeons had the highest average annual thyroid procedure volume with 78.2 cases/year, and pediatric surgeons and pediatric otolaryngologists had the lowest volumes with 0.7 and 0.6 cases/year, respectively. Overall complication rates were low. CONCLUSIONS: Operative management of pediatric thyroid disease was most frequently performed by pediatric surgery. Pediatric specializations are more likely to operate on low-income, minority children with public insurance and patients with Graves' disease. Overall complications were low. LEVEL OF EVIDENCE: III.

OBJECTIVE: To assess the risk of thyroid cancer in patients with Graves' disease (GD) after surgical treatment. MATERIAL AND METHODS: We retrospectively evaluated 121 patients with GD after thyroidectomy between December 2015 and January 2020. Thyroid cancer was confirmed by morphological analysis. Thyroid cancer occurred in 34 (28.1%) patients with GD after thyroidectomy. Preoperative ultrasound examination revealed nodular goiter in 62 (51.2%) patients. Nodular lesions were not found in other 59 (48.8%) patients with GD. RESULTS: Incidence of thyroid cancer was significantly higher in patients with nodular lesions (38% vs. 16%; p=0.009). Papillary thyroid cancer was detected in 32 out of 34 cases, follicular thyroid cancer - in 2 patients. Among 32 patients with papillary thyroid cancer, 28 ones had classical type, 2 patients - follicular variant of papillary cancer, 1 patient - oncocytic cancer, 1 patient - columnar cell variant of PTC. CONCLUSION: Risk of cancer is higher in patients with GD and nodes. In addition to standard examination of patients with GD, we performed ultrasound with examination of regional lymph nodes and analysis of further surgical tactics.

INTRODUCTION: Hypocalcemia is commonly reported after thyroidectomy and has multiple possible etiologies including: parathyroid devascularization, reactive hypoparathyroidism from relative hypercalcemia in thyrotoxicosis, and abrupt reversal of thyrotoxic osteodystrophy. In patients that are actively hyperthyroid and undergoing thyroidectomy, it is not known how many experience hypocalcemia from nonhypoparathyroidism etiologies. Therefore, our aim was to examine the relationship among thyrotoxicosis, hypocalcemia, and hypoparathyroidism. METHODS: A retrospective review was performed of prospectively-collected data from all patients undergoing thyroidectomy for hyperthyroidism by 4 surgeons from 2016 to 2020. All patients carried a diagnosis of Graves' disease or toxic multinodular goiter. Patient demographics, preoperative medications, laboratory reports, and postoperative medications were reviewed. Hypocalcemia within the first month of surgery despite a normal parathyroid hormone (PTH) level was the primary outcome of interest and was compared between patients with and without thyrotoxicosis. Secondary outcomes were duration of postoperative calcium use and the relationship between preoperative calcium supplementation and postoperative calcium supplementation. Descriptive statistics, Wilcoxon rank-sum, and chi-square tests were used for bivariate analysis, as appropriate. RESULTS: A total of 191 patients were identified, with mean age of 40.5 y (range 6-86). Most patients were female (80%) and had Graves' disease (80%). At the time of surgery, 116 (61%) had uncontrolled hyperthyroidism (thyrotoxic group, Free Thyroxine >1.64 ng/dL or Free Triiodothyronine > 4.4 ng/dL), with the remaining 75 (39%) considered euthyroid. Postoperative hypocalcemia (calcium < 8.4 mg/dL) developed in 27 (14%), while hypoparathyroidism (PTH < 12 pg/mL) was observed in 39 (26%). Thyrotoxic patients comprised a majority of those with hypocalcemia (n = 22, 81%, P = 0.01) and hypoparathyroidism immediately following surgery (n = 14, 77%, P = 0.04). However, a majority of initially hypocalcemic, thyrotoxic patients had normal PTH values within the first month after surgery (n = 17, 85%), pointing to a potential nonparathyroid etiology. On bivariate analysis, no significant relationship was found for thyrotoxic patients with initial postoperative hypocalcemia (18%) and hypoparathyroidism <1-month after surgery (29%, P = 0.29) or between 1 and 6 mo after surgery (2%, P = 0.24). Of the 19 patients in the nonhypoparathyroidism group, 17 (89%) were off all calcium supplements by 6 mo postop. CONCLUSIONS: In patients with hyperthyroidism, those in active thyrotoxicosis at time of surgery have a higher rate of postoperative hypocalcemia compared to euthyroid patients. When hypocalcemia lasts >1 mo postoperatively, data from this study suggest that hypoparathyroidism may not be the primary etiology in many of these patients, who typically require calcium supplementation no more than 6 mo postoperatively.

OBJECTIVES: Graves' disease (GD) is the most common cause of hyperthyroidism. Antithyroid drug (ATD) is often the first-line treatment but > 50% patients suffer a relapse when ATD is discontinued. Surgery or radioiodine remains the current options of definitive treatment in these patients. This pilot study examined the short-term efficacy of single-session thyroid radiofrequency ablation (RFA) as a novel definitive treatment for persistent/relapsed GD. METHODS: Consecutive patients with persistent/relapsed GD requiring ATD were considered. Those with a clear surgical indication, either thyroid lobe volume ≥ 20 mL; those who were pregnant or lactating; and those who had any severe medical conditions that would pose extra treatment risks were excluded. Eligible patients received ultrasound-guided RFA of the entire bulk of thyroid gland. Thyroid function tests were monitored bi-monthly. The primary outcome was disease remission rate, defined as a state of biochemical euthyroidism or hypothyroidism without ATD. Secondary outcomes were complication rates. RESULTS: Of the 68 patients considered, 15 (22.1%) patients were eligible. Most were females (93.3%). The median age was 37 (IQR 31-48) years old. The disease remission rates were 79.0% at 6 months and 73.3% at 12 months. Among the 4 patients who relapsed after RFA, three required less ATD dose than before RFA. RFA was well-tolerated in the ambulatory setting. There were no vocal cord palsy, skin burn, hematoma, or thyroid storm after RFA. CONCLUSIONS: In well-selected patients, single-session RFA of the thyroid gland may be a potential treatment for patients with persistent/relapsed GD. It is a safe and well-tolerated ambulatory procedure. KEY POINTS: ⢠Radiofrequency ablation of the thyroid gland is an efficacious treatment for persistent/relapsed Graves' disease in well-selected patients. ⢠Radiofrequency ablation of the thyroid gland for the treatment of persistent/relapsed Graves' disease is a safe and well-tolerated ambulatory procedure. ⢠Radiofrequency ablation of the thyroid gland may be a potential alternative treatment for well-selected patients with persistent/relapsed GD who do not wish to undergo either thyroidectomy or radioactive iodine or continue antithyroid drugs.

Although the success rates of non-surgical treatments for Graves' disease such as antithyroid medication and radioiodine ablation were good, there were still failure of treatments or intolerance for some patients. Traditional thyroid surgery could treat these patients but result in unaesthetic neck scars. Herein, we report the preliminary results of our combination of treatments with the transoral endoscopic thyroidectomy vestibular approach for Graves' disease. A retrospective review of patients who underwent the transoral endoscopic thyroidectomy vestibular approach for the treatment of different sizes of goiters between January 2019 and December 2020 was performed. The demographic and clinical data of patients were collected. All patients were followed up for > 12 months. Each patient's goiter size was determined using four grades-from 0 to 3. In total, 14 female patients receiving the combination treatment with > 1 year of follow-up and a median (range) age of 35 (20-48) years at surgery were included. There were two, three, four, and five patients with grade 0, 1, 2, and 3 goiters, respectively. The median (range) intraoperative blood loss was higher in grade 3 patients (100 [20-850] mL) than in grade 2 patients (20 [10-200] mL) and grade 1 and 0 patients (both < 10 mL) (p = 0.033). All patients had normal-looking necks with a euthyroid or hypothyroid status within 1 year. There were no complications, including re-operation for bleeding, hypoparathyroidism, vocal cord palsy, or infections. The designed combination treatment with the transoral endoscopic thyroidectomy vestibular approach for Graves' disease provides optimal cosmetic results with a high success rate.

Robotic thyroid surgeries in children are gaining popularity due to cosmetic advantages, but most previous studies include patients of school-age or older. We hereby introduce our case of a 5-year-old patient with Graves' disease to show key differences and similarities between pediatric and adult bilateral axillo-breast approach (BABA) robotic thyroidectomies. Despite the small body, no additional working space was needed and the flap creation was performed as similarly done in adults. The anatomy was not much different, except that the parathyroid tissues were easily identified due to low body fat, and the prominent thymus covered most of the level VI area. The patient did not experience postoperative complications such as hypoparathyroidism or vocal cord palsy. Postoperative wounds showed excellent results with minimal scars. BABA robotic thyroidectomy can be performed safely in pediatric patients and may be considered an alternative option for conventional open thyroidectomy in children.

INTRODUCTION: Graves' disease is an autoimmune disorder of the thyroid gland associated with the overproduction of thyroid hormones. Excess secretion of thyroid hormones leads to cardiovascular consequences. Treatment options include antithyroid medications (ATM), radioactive iodine (RAI) ablation, and total thyroidectomy. We examined the cardiovascular outcomes following Graves' disease management modality. METHODS: A systematic search was performed up to September 22nd, 2021, using PubMed, EMBASE, and Web of Science databases. We conducted a network meta-analysis analyzing cardiovascular outcomes of interest, including congestive heart failure (CHF), arrhythmia, atrial fibrillation (AF), and hypertension. RESULTS: Three studies were included in this analysis totaling 6700 patients with Graves' disease, of which 74% were female. The mean age was 44.34 y. When compared to pretreatment, management options lowered the risk of maintaining arrhythmia 81% with surgery (relative risk [RR] = 0.19; 95% confidence interval [CI] = 0.12 to 0.31), 67% with ATM (RR = 0.33; 95% CI = 0.23 to 0.49), and 50% with RAI (RR = 0.50; 95% CI = 0.13 to 1.95). Risk of maintaining CHF was reduced 80% with surgery (RR = 0.20; 95% CI = 0.08 to 0.49), 41% with ATM (RR = 0.59; 95%CI = 0.52 to 0.67), and only 7% with RAI (RR = 0.93; 95%CI = 0.68 to 1.26). Treatment-ranking analysis found all parameters, including CHF, arrhythmia, AF, and hypertension, to be in favor of surgical treatment over medical treatment and RAI ablation. CONCLUSIONS: This is the first network meta-analysis analyzing the cardiovascular outcomes in Graves' disease patients by treatment option. Our study demonstrated that surgery is superior to RAI and medical treatment.

Objective: Total thyroidectomy for Graves' disease (GD) is associated with rapid treatment of hyperthyroidism and low recurrence rates. However, it carries the risk of surgical complications including permanent hypoparathyroidism, which contributes to long-term impaired quality of life. The objective of this study was to determine the incidence of permanent hypoparathyroidism requiring calcitriol therapy among a population-based cohort of older adults undergoing total thyroidectomy for GD in the United States. Methods: We performed a population-based cohort study using 100% Medicare claims from beneficiaries older than 65 years with GD who underwent total thyroidectomy from 2007 to 2017. We required continuous enrollment in Medicare Parts A, B, and D for 12 months before and after surgery to ensure access to comprehensive claims data. Patients were excluded if they had a preoperative diagnosis of thyroid cancer or were on long-term preoperative calcitriol. Our primary outcome was permanent hypoparathyroidism, which was identified based on persistent use of calcitriol between 6 and 12 months following thyroidectomy. We used multivariable logistic regression to identify characteristics associated with permanent hypoparathyroidism, including patient age, sex, race/ethnicity, neighborhood disadvantage, Charlson-Deyo Comorbidity Index, urban or rural residence, and frailty. Results: We identified 4650 patients who underwent total thyroidectomy for GD during the study period and met the inclusion criteria (mean age = 72.8 years [standard deviation = 5.5], 86% female, and 79% white). Among this surgical cohort, 104 (2.2% [95% confidence interval, CI = 1.8-2.7%]) patients developed permanent hypoparathyroidism requiring calcitriol therapy. Patients who developed permanent hypoparathyroidism were on average older (mean age 74.1 vs. 72.8 years) than those who did not develop permanent hypoparathyroidism (p = 0.04). On multivariable regression, older age was the only patient characteristic associated with permanent hypoparathyroidism (odds ratio age ≥76 years = 1.68 [CI = 1.13-2.51] compared with age 66-75 years). Conclusions: The risk of permanent hypoparathyroidism requiring calcitriol therapy among this national, U.S. population-based cohort of older adults with GD treated with total thyroidectomy was low, even when considering operations performed by a heterogeneous group of surgeons. These findings suggest that the risk of hypoparathyroidism should not be a deterrent to operative management for GD in older adults who are appropriate surgical candidates.
