Implications of radiofrequency ablation in patients undergoing thyroid surgery for benign disease in the United States.

BACKGROUND: Radiofrequency ablation is an alternative strategy for the management of benign thyroid conditions. We analyzed the proportion of patients who underwent thyroid surgery for benign conditions who would be potentially eligible for radiofrequency ablation. METHODS: We identified patients who underwent thyroid surgery from 2015 to 2019 at the study institution for Bethesda II cytopathology or toxic adenoma. Patients were considered potentially eligible for radiofrequency ablation if they had a dominant nodule >2 cm with or without compression symptoms, a dominant nodule <2 cm with compression symptoms, or a toxic adenoma. RESULTS: Of 411 patients in total, 284 (69.1%) would be eligible to consider thyroid radiofrequency ablation. In the radiofrequency ablation-eligible group, 20 (7.0%) experienced voice change after surgery, and 2 (0.7%) were dissatisfied or concerned about their scar. In the radiofrequency ablation-eligible group, 70 patients (24.6%) had malignancy diagnosed by final pathology, and 23 patients (8.1%) had cancers that were equal to or larger than 1 cm in size. CONCLUSION: Many patients who undergo surgery for benign thyroid disease could be considered for radiofrequency ablation as an alternative treatment modality. Given the rate of occult malignancy, optimal evaluation of nondominant nodules before radiofrequency ablation and long-term thyroid surveillance for patients who undergo radiofrequency ablation should be further studied.

Surgical Management of Low-/Intermediate-Risk Node Negative Thyroid Cancer: A Single-Institution Study Using Propensity Matching Analysis to Compare Thyroid Lobectomy and Total Thyroidectomy.

Background: The approach for surgical treatment of patients with low-/intermediate-risk T1T2N0/Nx well-differentiated thyroid cancer (WDTC)-total thyroidectomy (TT) versus thyroid lobectomy (TL)-remains a controversial topic. Conducting a randomized controlled trial (RCT) would be the gold standard to address this issue. However, this is challenging due to excellent survival outcomes, and therefore, high number of patients and long-term follow-up would be required. As an alternative to RCT, we have used propensity score (PS) matching to determine if T1T2N0/Nx patients selected to have TL had equivalent outcomes to a similar group treated with TT. Methods: After institutional review board approval, a database of 6259 patients with WDTC treated with primary surgery at our institution between 1985 and 2016 was analyzed to identify patients with T1T2N0/Nx cancers. Of 3756 patients identified, 943 were managed by TL and 2813 by TT. To control for possible confounders and reduce potential bias, we selected age, sex, histology, 131I therapy, American Thyroid Association risk, and American Joint Committee Cancer stage as our PS matching criteria. Subsequently, 918 TL patients were successfully matched with 918 TT patients. The Pearson χ2 test or Fisher's exact test was used to compare categorical covariates, and Student's t-test was used for comparison of continuous variables between the two groups. Disease-specific survival (DSS), overall survival (OS), and recurrence-free survival (RFS) were calculated using the Kaplan-Meier method and compared using the log-rank test. Results: After PS matching, there were no significant differences between TL and TT patients for OS (10-year OS: 92.2% vs. 91.3%, p = 0.9668), DSS (10-year DSS: 100% vs. 99.1%, p = 0.1967), or RFS (10-year RFS: 99.5% vs. 98.3%, p = 0.079). Conclusions: For low-/intermediate-risk patients with intrathyroidal thyroid cancer <4 cm, patients selected for TL have similar survival outcomes to a comparable group treated by TT.

Patient-Reported Outcomes Following Total Thyroidectomy for Graves' Disease.

Background: Graves' disease accounts for ∼80% of all cases of hyperthyroidism and is associated with significant morbidity and decreased quality of life. Understanding the association of total thyroidectomy with patient-reported quality-of-life and thyroid-specific symptoms is critical to shared decision-making and high-quality care. We estimate the change in patient-reported outcomes (PROs) before and after surgery for patients with Graves' disease to inform the expectations of patients and their physicians. Methods: PROs using the MD Anderson Symptom Inventory (MDASI) validated questionnaire were collected prospectively from adult patients with Graves' disease from January 1, 2015, to November 20, 2020, on a longitudinal basis. Survey responses were categorized as before surgery (≤120 days), short term after surgery (<30 days; ST), and long term after surgery (≥30 days; LT). Negative binomial regression was used to estimate the association of select covariates with PROs. Results: Eighty-five patients with Graves' disease were included. The majority were female (83.5%); 47.1% were non-Hispanic white and 35.3% were non-Hispanic black. The median thyrotropin (TSH) value before surgery was 0.05, which increased to 0.82 in ST and 1.57 in LT. In bivariate analysis, the Total Symptom Burden Score, a composite of all patient-reported burden, significantly reduced shortly after surgery (before surgery mean of 56.88 vs. ST 39.60, p < 0.001), demonstrating improvement in PROs. Furthermore, both the Thyroid Symptoms Score, including patient-reported thermoregulation, palpitations, and dysphagia, and the Quality-of-Life Symptom Score improved in ST and LT (thyroid symptoms, before surgery 13.88 vs. ST 8.62 and LT 7.29; quality of life, before surgery 16.16 vs. ST 9.14 and LT 10.04, all p < 0.05). After multivariate adjustment, the patient-reported burden in the Thyroid Symptom Score and the Quality-of-Life Symptom Score exhibited reduction in ST (thyroid symptoms, rate ratio [RR] 0.55, confidence interval [CI]: 0.42-0.72; quality of life, RR 0.57, CI: 0.40-0.81) and LT (thyroid symptoms, RR 0.59, CI: 0.44-0.79; quality of Life, RR 0.43, CI: 0.28-0.65). Conclusions: Quality of life and thyroid-specific symptoms of Graves' patients improved significantly from their baseline before surgery to both shortly after and longer after surgery. This work can be used to guide clinicians and patients with Graves' disease on the expected outcomes following total thyroidectomy.

Informed Consent for Intraoperative Neural Monitoring in Thyroid and Parathyroid Surgery - Consensus Statement of the International Neural Monitoring Study Group.

In the past decade, the use of intraoperative neural monitoring (IONM) in thyroid and parathyroid surgery has been widely accepted by surgeons as a useful technology for improving laryngeal nerve identification and voice outcomes, facilitating neurophysiological research, educating and training surgeons, and reducing surgical complications and malpractice litigation. Informing patients about IONM is not only good practice and helpful in promoting the efficient use of IONM resources but is indispensable for effective shared decision making between the patient and surgeon. The International Neural Monitoring Study Group (INMSG) feels complete discussion of IONM in the preoperative planning and patient consent process is important in all patients undergoing thyroid and parathyroid surgery. The purpose of this publication is to evaluate the impact of IONM on the informed consent process before thyroid and parathyroid surgery and to review the current INMSG consensus on evidence-based consent. The objective of this consensus statement, which outlines general and specific considerations as well as recommended criteria for informed consent for the use of IONM, is to assist surgeons and patients in the processes of informed consent and shared decision making before thyroid and parathyroid surgery.

Explore the Diagnostic Efficiency of Chinese Thyroid Imaging Reporting and Data Systems by Comparing With the Other Four Systems (ACR TI-RADS, Kwak-TIRADS, KSThR-TIRADS, and EU-TIRADS): A Single-Center Study.

Purpose: To explore the characteristics of C-TIRADS by comparing it with ACR-TIRADS, Kwak-TIRADS, KSThR-TIRADS and EU-TIRADS. Methods: A total of 1096 nodules were collected from 884 patients undergoing thyroidectomy in our center between May 2018 and December 2020. Divided the nodules into two groups: ">10mm" and "≤10mm". Ultrasound characteristics of each nodule were observed and recorded by 2 doctors, then classified based on ACR-TIRADS, Kwak-TIRADS, KSThR-TIRADS, EU-TIRADS, and C-TIRADS. Results: A total of 682 benign nodules cases (62.23%) and 414 malignant nodules cases (37.77%) were identified. The ICC value of each guideline was:0.937(ACR-TIRADS), 0.858(EU-IRADS), 0.811(Kwak-TIRADS), 0.835(KTA/KSThR-TIRADS) and 0.854(C-TIRADS). The nodule malignancy rates in the groups(Kwak-TIRADS 4B, C-TIRADS 4B、4C) of two sizes were significantly different (all p<0.05). There was no statistical difference in the other grades of two sizes (all p>0.05). Unnecessary biopsy rates were the lowest in C-TIRADS (49.02% p<0.001). Furthermore, Kwak-TIRADS had the highest sensitivity and NPV (89.9%, 91.0%, all p<0.05), while C-TIRADS had the highest specificity and PPV (82.3%, 69.2%, all p<0.05). C-TIRADS and Kwak-TIRADS had the highest accuracy (76.0%, 72.5%, P=0.071). The AUCs of the 5 guidelines were C-TIRADS(0.816, P<0.05), Kwak-TIRADS(0.789, P<0.05) KTA/KSThR-TIRADS and ACR-TIRADS(0.773, 0.763, P=0.305), EU-TIRADS(0.734, P<0.05). The AUCs of the five guidelines were not statistically different between "nodules>10mm" and "nodules ≤ 10mm" (all P>0.05). Conclusions: All five guides showed excellent interobserver agreement. C-TIRADS was slightly efficient than Kwak-IRADS, KTA/KSThR-TIRADS and ACR-TIRADS, and had greater advantages than EU-TIRADS. The diagnostic abilities of the five guidelines for "nodules ≤ 10mm" were not inferior to that of "nodules> 10mm". C-TIRADS is simple and easy to implement and can provide effective thyroid tumor risk stratification for thyroid nodule diagnosis, especially in China.

Factors Influencing Hypertrophic Scarring after Thyroidectomy.

OBJECTIVE: To identify the risk factors of hypertrophic scarring (HS) after thyroidectomy and construct a risk prediction model. METHODS: From November 2018 to March 2019, the clinical data of patients undergoing thyroidectomy were collected for retrospective analysis. According to the occurrence of HS, the patients were divided into an HS group and a non-HS group. Univariate analysis and binary logistic regression analysis were conducted to explore the independent risk factors for HS. Receiver operating characteristic analysis was also carried out. RESULTS: In this sample, 121 of 385 patients developed HS, an incidence of 31.4%. Univariate analysis showed significant differences in sex, age, postoperative infection, history of abnormal wound healing, history of pathologic scar, family history of pathologic scar, and scar prevention measures between the two groups (P < .05). Binary logistic regression analysis indicated that age 45 years or younger (odds ratio [OR], 1.815), history of abnormal wound healing (OR, 4.247), history of pathologic scarring (OR, 9.840), family history of pathologic scarring (OR, 5.708), and absence of preventive scar measures (OR, 5.566) were independent factors for HS after thyroidectomy. The area under the receiver operating characteristic curve was 0.837. When the optimal diagnostic cutoff value was 0.206, the sensitivity was 0.661, and the specificity was 0.932. CONCLUSIONS: The development of HS after thyroidectomy is related to many factors, and the proposed risk prediction model based on the combined risk factors shows a good predictive value for postoperative HS. When researchers consider the prevention and treatment of scarring in patients at risk, the incidence of HS in different populations can provide theoretical support for clinical decision-making.

Rapid standardized operating rooms (RAPSTOR) in thyroid and parathyroid surgery.

OBJECTIVE: To evaluate the impact of a high efficiency rapid standardized OR (RAPSTOR) for hemithyroid/parathyroid surgery using standardized equipment sets (SES) and consecutive case scheduling (CCS) on turnover times (TOT), average case volumes, patient outcomes, hospital costs and OR efficiency/stress. METHODS: Patients requiring hemithyroidectomy (primary or completion) or unilateral parathyroidectomy in a single surgeon's practice were scheduled consecutively with SES. Retrospective control groups were classified as sequential (CS) or non-sequential (CNS). A survey regarding OR efficiency/stress was administered. Phenomenography and descriptive statistics were conducted for time points, cost and patient outcome variables. Hospital cost minimization analysis was performed. RESULTS: The mean TOT of RAPSTOR procedures (16 min; n = 27) was not significantly different than CS (14 min, n = 14) or CNS (17 min, n = 6). Mean case number per hour was significantly increased in RAPSTOR (1.2) compared to both CS (0.9; p < 0.05) and CNS (0.7; p < 0.05). Average operative time was significantly reduced in RAPSTOR (32 min; n = 28) compared to CNS (48 min; p < 0.05) but not CS (33 min; p = 0.06). Time to discharge was reduced in RAPSTOR (595 min) compared to CNS (1210 min, p < 0.05). There was no difference in complication rate between all groups (p = 0.27). Survey responses suggested improved efficiency, teamwork and workflow. Furthermore, there is associated decrease in direct operative costs for RAPSTOR vs. CS. CONCLUSION: A high efficiency standardized OR for hemithyroid and parathyroid surgery using SES and CCS is associated with improved efficiency and, in this study, led to increased capacity at reduced cost without compromising patient safety. LEVEL OF EVIDENCE: Level 2.

Nomograms to predict ipsilateral and contralateral central lymph node metastasis in clinically lymph node-negative patients with solitary isthmic classic papillary thyroid carcinoma.

BACKGROUND: Isthmus-originating papillary thyroid carcinoma has unique clinicopathological characteristics. There are no specific guidelines regarding the extent of surgery for isthmic papillary thyroid carcinoma. We aimed to evaluate the characteristics of clinically lymph node-negative patients with solitary isthmic papillary thyroid carcinoma and to determine the best surgical protocol for these patients. METHODS: A total of 904 patients diagnosed with solitary papillary thyroid carcinoma who underwent surgery were retrospectively reviewed. These patients were divided into the isthmic group (246 patients) or lobar group (658 patients). We compared the 2 groups and conducted a multivariate analysis to assess risk factors for ipsilateral and contralateral central lymph node metastasis in isthmic papillary thyroid carcinoma patients. Nomograms for predicting central lymph node metastasis in isthmic papillary thyroid carcinoma patients were developed and internal calibration was performed for these models. RESULTS: Isthmic papillary thyroid carcinoma patients have a significantly higher incidence of extrathyroidal extension and central lymph node metastasis than do lobar papillary thyroid carcinoma patients. For isthmic papillary thyroid carcinoma patients, sex, BRAF V600E mutation, chronic lymphocytic thyroiditis, tumor size, margin, and extrathyroidal extension were independent risk factors of ipsilateral central lymph node metastasis. Body mass index, BRAF V600E mutation, tumor size, location, and extrathyroidal extension were independent risk factors of contralateral central lymph node metastasis. All the above factors were incorporated into nomograms, which showed the perfect discriminative ability. CONCLUSION: Based on the predictive nomograms, we proposed a risk stratification scheme and corresponding individualized surgical treatment based on different nomogram scores. In the debate about prophylactic central neck dissection among clinically lymph node-negative patients with solitary isthmic papillary thyroid carcinoma, our nomograms provide the balance to avoid overtreatment and undertreatment through personal risk assessment.

Calcitonin Stimulation Tests: Rationale, Technical Issues and Side Effects: A Review.

Calcitonin (CT) stimulation tests have great value and could help to: differentiate thyroid causes of elevated CT apart from non-thyroid sources, determine whether the patients with slightly elevated basal CT could/could not be candidates for surgery, and indicate the right moment for prophylactic thyroidectomy in children with MEN syndromes when with normal basal CT. This triggered the requests for development of CT stimulation tests, taking into consideration their safety and aimed us to write a systematic review of literature regarding the rationale, technical issues, and side effects of CT stimulating tests used for diagnosis of MTC. After a thorough review of the literature, we classified the reported side effects by severity, as defined by United States Food and Drug Administration. A statistical analysis was performed using IBM SPSS Statistics version 20. Various side effects were noticed during stimulation tests that differ by intensity, duration and severity, depending on types of substances and protocols used. The side effects after pentagastrin test were significantly more severe than those reported after calcium stimulation test (p=0.0396). There are also significant gender-specific differences in side effects induced by stimulation tests. In conclusion, we recommend performing Ca CT stimulation test when needed, considering preventive evaluation of some clinical, instrumental, and biochemical aspects of each patient. Precise instructions should be followed before a stimulation test and furthermore continuous cardiac monitoring is essential during and after the test to minimize the possibility of a serious event.

A Novel and Generic Workflow of Indocyanine Green Perfusion Assessment Integrating Standardization and Quantification Toward Clinical Implementation.

OBJECTIVE: This study aims to generate a reproducible and generalizable Workflow model of ICG-angiography integrating Standardization and Quantification (WISQ) that can be applied uniformly within the surgical innovation realm independent of the user. SUMMARY BACKGROUND DATA: Tissue perfusion based on indocyanine green (ICG)-angiography is a rapidly growing application in surgical innovation. Interpretation of results has been subjective and error-prone due to the lack of a standardized and quantitative ICG-workflow and analytical methodology. There is a clinical need for a more generic, reproducible, and quantitative ICG perfusion model for objective assessment of tissue perfusion. METHODS: In this multicenter, proof-of-concept study, we present a generic and reproducible ICG-workflow integrating standardization and quantification for perfusion assessment. To evaluate our model's clinical feasibility and reproducibility, we assessed the viability of parathyroid glands after performing thyroidectomy. Biochemical hypoparathyroidism was used as the postoperative endpoint and its correlation with ICG quantification intraoperatively. Parathyroid gland is an ideal model as parathyroid function post-surgery is only affected by perfusion. RESULTS: We show that visual subjective interpretation of ICG-angiography by experienced surgeons on parathyroid perfusion cannot reliably predict organ function impairment postoperatively, emphasizing the importance of an ICG quantification model. WISQ was able to standardize and quantify ICG-angiography and provided a robust and reproducible perfusion curve analysis. A low ingress slope of the perfusion curve combined with a compromised egress slope was indicative for parathyroid organ dysfunction in 100% of the cases. CONCLUSION: WISQ needs prospective validation in larger series and may eventually support clinical decision-making to predict and prevent postoperative organ function impairment in a large and varied surgical population.

MANAGEMENT OF ENDOCRINE DISEASE: Papillary thyroid microcarcinoma: toward an active surveillance strategy.

In the last decades, the incidence of thyroid cancer (TC) has more than doubled, but the disease-specific mortality rate was stable. To date, 30-40% of all TC is represented by papillary microcarcinomas (mPTC), an indolent tumor, that probably remained undiagnosed before routine ultrasound use. In 1993, Miyauchi was the first who hypothesized a conservative approach for low-risk mPTC and introduced the concept of active surveillance (AS) in its clinical management. The progression rate of mPTC during AS was low and delaying surgery did not impact the efficacy of treatment or outcome. Since then, several authors from all over the world have reported their experience of AS in mPTCs. As suggested by current guidelines, AS can be considered as an alternative to immediate surgery to avoid overtreatment in low-risk mPTC and may be the strategy to avoid complications from unnecessary surgery. In the last years, AS inclusion criteria have been extended to both bigger tumors and to younger/healthier patients. The adoption of AS should take into consideration not only tumor characteristics but also patient psychological profiles and medical team expertise. Its safety and efficacy have been demonstrated in long-term outcome studies and in other types of tumors; however, skepticism in patients, families and physicians should be overcome by strong recommendations coming from scientific guidelines. This review analyses the several and different experiences of AS and the potential obstacles in implementing it as a routine approach in mPTC patients.

A single institution experience with papillary thyroid cancer: Are outcomes better at comprehensive cancer centers?

INTRODUCTION: Papillary thyroid cancer (PTC) is the most common form of thyroid cancer. Although the survival rate is excellent, recurrence is as high as 20%. The mainstay of therapy is thyroidectomy and lymph node dissection based on risk factors. Data from other cancers suggest that surgical outcomes are most optimal at comprehensive cancer centers. We hypothesize that patients with PTC who had their initial operation at a comprehensive cancer center would have a better oncologic outcome. METHODS: We utilized an IRB-approved cancer care registry database of patients with thyroid cancer who were seen at our institution between 2000 and 2018. Patient records were updated with cancer-specific outcomes including recurrence and need for re-intervention. Clinical and surgical outcomes were then compared between patients who had their initial operation at a comprehensive cancer center (CCC group, n = 503) versus those who did not (non-CCC group, n = 72). RESULTS: Mean patient age was 49 ± 16 years and 70% were female. Average tumor size was 1.6 ± 1.6 cm. There was no difference in tumor size, age, gender or race between groups. Pre-operative ultrasound was more frequently performed at the CCC (89%) than at non-CCC's (51%, p < 0.001). CCC patients were more likely to undergo initial total thyroidectomies compared to non-CCC patients (76% vs. 21%, p < 0.001). Positive surgical margins were more frequently found in patients at non-CCC's (19%) than at the CCC (9.7%, p = 0.016). Finally, CCC patients had a significantly lower cancer recurrence rate (5.0% vs. 37.5%, p < 0.001). Therefore, the need for additional cancer operations was much greater in patients who had initial thyroid surgery at non-CCC (31.9% vs. 1.4%, p < 0.001). CONCLUSIONS: Patients with PTC who have their initial thyroidectomy at non-CCC have higher recurrence rates, higher rates of positive tumor margins on pathology, and increased need for additional operations. These data suggest that patients who have their initial procedure at a CCC for PTC have better long-term outcomes.

Trends and Outcomes of Surgical Management of Primary Papillary Carcinoma in the Pediatric Population.

BACKGROUND: Childhood papillary thyroid cancer is more aggressive than carcinomas in adults. Current American Thyroid Association pediatric guidelines recommend a total or near-total thyroidectomy for all pediatric patients without gross evidence of lymph node metastases. Our objective is to analyze trends in the surgical management of pediatric papillary thyroid cancer and assess how well the guidelines are implemented. METHODS: A retrospective cohort study of pediatric patients (ages 19 y and under) who underwent a thyroidectomy was conducted using the Surveillance, Epidemiology, and End Results database 2006-2017. Procedure type was classified as lobectomy or less and subtotal or total thyroidectomy. Descriptive statistics to illustrate patient and tumor characteristics as well as chi-square analysis to evaluate frequency of treatment with total thyroidectomies versus lobectomy or less were performed. Logistic regression analysis controlling for age, sex, size of tumor, rural versus urban institutions, and surgery year was conducted to identify factors predictive of procedure type. RESULTS: A total of 2271 children underwent surgical management of papillary thyroid cancer between 2006 and 2017. Most patients received a subtotal or total thyroidectomy as surgical management (n = 2,085, 91.8%). One hundred eighty-six patients (8.2%) received a lobectomy or less. The number of lobectomies or less increased with time, with 41 (6.6%) patients between 2006 and 2009, 98 (8.0%) between 2009 and 2015, and 47 (11.1%) between 2016 and 2017 (P = 0.03). Mortality rates were low (n = 15, 0.7%). On logistic regression analysis, later stages, larger sizes, and earlier operative years were predictive of a near-total or total thyroidectomy. CONCLUSIONS: Despite the American Thyroid Association Guidelines recommending a total thyroidectomy for pediatric well-differentiated thyroid cancer, the results of this study demonstrate that thyroid lobectomies are being performed in increasing frequency for smaller tumors in earlier stages of disease. Further investigation of whether this trend actually affects the outcomes in this patient cohort is needed.

Reoperative Cervical Endocrine Surgery: Appropriate Valuation for the Time and Effort?

BACKGROUND: Controversies currently exist regarding the best way to appropriately quantify complexity and to benchmark reimbursement for surgeons. This study aims to analyze surgeon reimbursement in primary and redo-thyroidectomy and parathyroidectomy using operative time as a surrogate for complexity. METHODS: A retrospective analysis using the National Surgical Quality Improvement Program database was performed to identify patients who underwent primary and redo-thyroidectomy and parathyroidectomy. Calculations of median operative time work relative value units per minute and dollars per minute were compared between primary and redo procedures. RESULTS: Thyroidectomy cases represented 53.5% (22,521 cases), and the other 46.5% (19,596 cases) were parathyroidectomy cases. The median dollars per minute in primary thyroidectomy was $4.97 and for redo-thyroidectomy was $8.12 (P < 0.0001). By the same token, dollars per minute were higher in the redo cases with $15.40 when compared with primary parathyroidectomy cases with $13.14 dollars per minute (P < 0.0001). CONCLUSIONS: By Current Procedural Terminology codes, surgeons appear to be appropriately reimbursed for redo-thyroid and parathyroid procedures indexed to first time parathyroidectomy based on the compensated operative time of these procedures calculated using a nationally representative sample.

A Qualitative Study of Developing Competency in Thyroid Surgery: A Resident's Perspective With 5 Year Follow Up.

OBJECTIVES: The Accreditation Council for Graduate Medical Education has guidelines on assessing surgical qualifications based on experience. Attending surgeons have various assumptions on how their trainees learn and acquire surgical skills. This study primarily investigates the resident's perspective on gaining experience and achieving competency in thyroid surgical procedures. METHODS: A qualitative study using semi-structured interviews was designed to derive themes that discuss the acquisition of competency in thyroid surgery. After IRB approval, data was collected from 2012 to 2014 at 4 academic centers in the Washington, DC area. Fourteen chief residents specializing in either general surgery or otolaryngology were interviewed until saturation was achieved. These semi-structured interviews were transcribed and broken up into codes utilizing Moustakas' analysis. A comprehensive list of master themes in regards to achieving competency in thyroid surgery was developed. A follow up survey of the surgeons was undertaken at 5 years to determine if the perceptions during residency persisted in practice. RESULTS: Surgical specialty residents experience and learn thyroid surgery in 5 learning themes:1. Self-directed learning is significant during residency.2. Repetition with graduated autonomy is key.3. Effective mentors are competent surgeons who challenge residents and use positive teaching techniques.4. Residents employ active learning through the "see one, do one, teach one" philosophy.5. Learning from complexity is of importance to residency training.After several years in practice, the most important theme in learning after residency was repetition of cases. CONCLUSIONS: This study demonstrates how residents progress in approaching competency in thyroid surgery. Adult learning strategies are preferred, and programs should incorporate tailored techniques to meet the individual needs of the residents. Perceptions of what is most important shifted in long-term follow up. Further study is needed to assure competency in residency and in practice.

Detailed comparison of the da Vinci Xi and S surgical systems for transaxillary thyroidectomy.

ABSTRACT: Robotic surgical systems have evolved over time. The da Vinci Xi system was developed in 2014 and was expected to solve the shortcomings of the previous S system. Therefore, we conducted this study to compare these 2 systems and identify if the Xi system truly improves surgical outcomes.In this retrospective study, a total of 86 patients with unilateral papillary thyroid carcinoma without central lymph node involvement underwent gasless transaxillary hemithyroidectomy using 2 robotic systems, the da Vinci S and Xi. Forty patients were in the da Vinci S group and 46 patients were in the da Vinci Xi group. All surgeries were performed by 1 surgeon (YWC). All surgery video files were analyzed to compare the duration of each surgical step.The total operation time was significantly shorter in the Xi group than in the S group (153.0 minutes vs 105.7 minutes, P < .01). Time for robot docking was shorter in the Xi group (19.8 minutes vs 10.6 minutes, P < .01), and all procedures performed in the console also required a shorter time in this group. The overall complication rate did not differ significantly (P = .464).The da Vinci Xi system made robotic thyroidectomy easier and faster without increasing the complication rate. It is a safe and valuable system for robotic thyroidectomy.

Ambulatory Endoscopic Thyroidectomy via a Chest-Breast Approach Has an Acceptable Safety Profile for Thyroid Nodule.

Introduction: With the growing esthetic requirements, endoscopic thyroidectomy develops rapidly and is widely accepted by practitioners and patients to avoid the neck scar caused by open thyroidectomy. Although ambulatory open thyroidectomy is adopted by multiple medical centers, the safety and potential of ambulatory endoscopic thyroidectomy via a chest-breast approach (ETCBA) is poorly investigated. Material and Methods: Patients with thyroid nodules who received conventional or ambulatory ETCBA at Xiangya hospital, Central South University from January 2017 to June 2020 were retrospectively included. The incidence of postoperative complications, 30-days readmission rate, financial cost, duration of hospitalization, mental health were mainly investigated. Results: A total of 260 patients were included with 206 (79.2%) suffering from thyroid carcinoma, while 159 of 260 received ambulatory ETCBA. There was no statistically significant difference in the incidence of postoperative complications (P=0.249) or 30-days readmission rate (P=1.000). In addition, The mean economic cost of the ambulatory group had a 29.5% reduction compared with the conventional group (P<0.001). Meanwhile, the duration of hospitalization of the ambulatory group was also significantly shorter than the conventional group (P<0.001). Patients received ambulatory ETCBA showed a higher level of anxiety (P=0.041) and stress (P=0.016). Subgroup analyses showed consistent results among patients with thyroid cancer with a 12.9% higher complication incidence than the conventional ETCBA (P=0.068). Conclusion: Ambulatory ETCBA is as safe as conventional ETCBA for selective patients with thyroid nodules or thyroid cancer, however with significant economic benefits and shorter duration of hospitalization. Extra attention should be paid to manage the anxiety and stress of patients who received ambulatory ETCBA.

Racial disparities in comorbid conditions among patients undergoing thyroidectomy for Graves' disease: An ACS-NSQIP analysis.

BACKGROUND: Studies indicate that racial disparities exist in the presentation and outcomes of patients undergoing thyroidectomy for cancer and benign disease. We examined the relationship between race, pre-operative characteristics and outcomes in patients undergoing thyroidectomy for GD. METHODS: Patients were identified from the 2013-2016 American College of Surgeons NSQIP database using ICD-9/10 codes consistent with diffuse toxic goiter. RESULTS: AA patients were more likely to have an ASA classification of ≥3 (41% vs 30%, p < 0.001), a higher rate of CHF (2.1% vs 0.5%, p = 0.01), hypertension (46% vs 32%, p < 0.001) and dyspnea (10% vs 5%, p < 0.001) compared to Non-Hispanic Caucasians (NH-C) patients. Complications were higher in patients with ASA≥3 and CHF but not affected by race. CONCLUSIONS: Analysis of a national database of thyroidectomy for GD revealed a higher burden of preoperative comorbidities in AA patients compared to other races, although race was not an independent predictor of outcomes.

Practice patterns for surgical management of low-risk papillary thyroid cancer from 2014 to 2019: A CESQIP analysis.

BACKGROUND: Patients with low-risk-PTC who undergo thyroid lobectomy (TL) have comparable disease-specific survival with lower morbidity than total thyroidectomy (TT). We aim to describe the surgical management of low-risk-PTC using the Collaborative Endocrine Surgery Quality Improvement Program (CESQIP). METHOD: CESQIP thyroidectomies of PTC tumors <4 cm were analyzed from 2014 to 2019 (n = 740). Postoperative outcomes were compared. Subgroup analysis examined temporal and institutional trends, and stratified for tumor size. Statistics utilized t-test, ANOVA, and Chi-squared. RESULTS: TT patients had greater hypoparathyroidism, operative time, and length-of-stay (all p < 0.001). Incidence of TL decreased with increasing tumor size (24.2% for <1 cm, 15.8% for 1-2 cm, 6.1% for 2-4 cm). TL rates increased from 2.0% in 2014 to 21.2% in 2018-19. Completion thyroidectomy was recommended in 12.0% of TL subjects. There was significant variation in TL rate by institution (p < .001). CONCLUSIONS: For low-risk-PTC, TT remained the most commonly utilized operation. TL rates increased following release of the new ATA guidelines. TT was associated with higher perioperative morbidity. Further insight is needed to understand factors influencing operative approach.
