Background: Lymph node metastases in papillary thyroid cancer (PTC) increases recurrence risk and negatively impact survival. Traditional treatments like re-operation and radioactive iodine (RAI) have downsides. Radiofrequency ablation (RFA) is an emerging non-surgical therapeutic option, but there is seldom data on its efficacy and safety specifically for metastatic lymph nodes. We aimed to evaluate clinical outcomes of RFA applied to cervical lymph nodes in patients with PTC metastasis in North American population., Methods: This was a single-institution retrospective analysis of 68 PTC patients with lymph nodes who underwent percutaneous RFA from January 2020 to December 2022. Volume reduction ratio (VRR), changes in thyroglobulin (Tg) levels, lymph node regrowth rate, and complications were assessed. Treatment response and outcomes were analyzed., Results: Median lymph node maximum diameter was 12.9 mm and median volume was 0.27 mL at baseline. After RFA, median VRR was 79.5% [interquartile range (IQR), 50-89.7%]. Post-RFA, Tg to an average of 0.2 ng/mL (IQR, 0-0.6 ng/mL). In the 19 patients (27.9%) with undetectable Tg after RFA, median VRR was 86% (IQR, 73-94%). Quantitative Tg decrease strongly correlated with VRR percentage (r=0.82, P<0.001). Lymph node regrowth was seen in 5 patients (7.4%) over median 18 months follow-up. Only one patient experienced transient thermal injury associated with Horner's syndrome and symptoms resolved within 1 month., Conclusions: In patients with PTC and metastatic cervical lymph nodes, RFA provided marked volume reduction and meaningful biochemical response without major complications. Excellent radiographic control was achieved in most patients. RFA demonstrates early promise as an emerging non-surgical therapeutic option for PTC patients with metastatic lymph nodes., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://gs.amegroups.com/article/view/10.21037/gs-24-285/coif).

Microwave ablation (MWA) is a novel modality for thermal ablation (TA) to treat benign and malignant thyroid nodules, mostly papillary thyroid cancer (PTC). Compared to surgery, TA is less invasive and less painful, has faster recovery, better cosmetic outcomes, and fewer complications. TA techniques have been evolving over the past decade to be more energy efficient, precise, and produce long-lasting results. The general approach is similar between various TA techniques. However, each technique has uniqueness in its energy delivery and, thus, risk profile and outcomes. MWA has a few critical technical differences that make it safer for patients with surgical implants and cardiac comorbidities. It has proven effective in treating benign thyroid nodules (BTNs) in adults and pediatric populations with benign and malignant lesions. The clinical and theoretical outcomes of MWA compared to other thermal ablative techniques, such as radiofrequency ablation (RFA) and laser ablation (LA), have been investigated in some studies and meta-analyses. Minimally invasive procedures such as MWA are an important tool for the management of thyroid lesions. Thus, it is crucial for clinicians to be equipped with the knowledge to use these tools. In this review, we provide a clinical review detailing the technical differences and clinical outcomes for the three major TA techniques-MWA, RFA, and LA., Competing Interests: Conflicts of Interest: Both authors have completed the ICMJE uniform disclosure form (available at https://gs.amegroups.com/article/view/10.21037/gs-24-221/coif).

Background and Objective: The interwoven immunological, biological, and genetic complexity of thyroid diseases makes suitable targeted therapies particularly challenging to develop. Stemming from ancient practices, al-hijamah, or wet cupping, has achieved notable popularity in recent years, leading to unique applications in modern medicine. By grappling with the current literature that links the effects of wet cupping with the immune system in patients with Hashimoto's thyroiditis (HT), this narrative review aims to compose a comprehensive assessment of this adjunctive treatment based on evidence of its integration into practice., Methods: Between upregulating critical players of the innate immune system, such as immunostimulatory cytokines, white blood cells (WBCs) and natural killer (NK) cells, and downregulating essential thyroid antibodies (anti-thyroid peroxidase and anti-thyroglobulin) and inflammatory markers (C-reactive protein and erythrocyte sedimentation rate), wet cupping practices provide promising complementary therapy for hypothyroidism., Key Content and Findings: Wet cupping manipulates in vivo molecular mechanisms, as outlined in hemodynamic and microparticle clearance theories, to slow disease progression and even development in disease-free populations. Given the established utilization of wet cupping in the context of autoimmune diseases and inflammatory conditions, the emerging utility of wet cupping continues to gain credibility., Conclusions: This literature review illuminates the documented improvements in immune and biological function due to cupping therapeutic practices and sheds light on its appropriate application in the clinical setting for patients with HT. Furthermore, this review proposes a clear need for implementing future clinical trials, which may effectively bridge pathophysiological causes of hypothyroidism with underrated techniques for enhanced thyroid health., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://gs.amegroups.com/article/view/10.21037/gs-24-173/coif).

Radiofrequency ablation (RFA) is a minimally invasive ablative modality for the treatment of thyroid nodules. Reports of RFA use have demonstrated an impressive safety profile and excellent volume reduction rates between 60-90%. Given its increased popularity in the United States as well as globally, numerous recent works have been published and a discussant of relevant complications incorporating recent insight may assist practitioners in minimizing complications and optimizing patient outcomes. Herein, we provide a comprehensive and updated review of the reported complications and side effects following RFA, summarizing their frequency and clinical presentation. We also describe a means of minimizing such complications and/or side effects. Overall, the safety profile of RFA is impressive and superior to that of thyroid surgery. The overall risk of complication is reportedly 2-3%. The risk of permanent complication or severe injury is very unlikely, below 1%. Complications are infrequent, but may be nerve-related, endocrine-related, or iatrogenic-related, and consequences of localized heat delivery. The vast majority of complications related to RFA can be managed conservatively, without need for invasive measures. This review will assist surgeons and clinicians in recognizing and treating the various complications and side effects in clinical practice., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://gs.amegroups.com/article/view/10.21037/gs-22-539/coif).

Percutaneous ethanol injection (PEI) is a widely used treatment option for cystic and predominantly cystic thyroid nodules. It has several advantages over other treatment modalities. Compared to surgery, PEI is less painful, can be performed in the outpatient setting, and carries less risk of transient or permanent side effects. Compared to other minimally invasive techniques such as radiofrequency ablation (RFA), PEI is less expensive and does not require specialized equipment. PEI performs well in the context of cystic nodules. PEI does not perform as well as other techniques in solid nodules, so its use as a primary treatment is limited to cystic and predominantly cystic thyroid nodules. However, PEI is also being explored as an adjunct treatment to improve ablation of solid nodules with other techniques. Here, we provide a clinical review discussing the genesis, mechanism of action, and patient selection with respect to ethanol ablation, as well as the procedure itself. Predictors of operative success, failure, and common adverse events are also summarized. Altogether, PEI allows impressive volume reduction rates with minimal complications. Several recent studies have also evaluated the long-term impact of PEI up to 10 years after treatment and revealed maintenance of robust treatment efficacy with no undesirable long-term sequelae. Thus, PEI remains the treatment of choice for benign but symptomatic cystic and predominantly cystic thyroid nodules., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://gs.amegroups.com/article/view/10.21037/gs-22-568/coif). The series “RFA and Recent Innovations in Endocrine Surgery” was commissioned by the editorial office without any funding or sponsorship.

Background: Radiofrequency ablation (RFA) utilizes minimally invasive high-energy current to precisely ablate tumor cells. It has been utilized in many cancer types including thyroid, lung, and liver cancer. It has been shown to provide adequate ablative margins with minimal complications; however, incomplete RFA may lead to recurrence of tumor. The underlying cellular mechanism and behavior of ablated cancer tissue is poorly understood., Methods: A systematic review was performed, searching EMBASE, Web of Science, PubMed, and Scopus for studies published up to March 2022 and reported following PRISMA guidelines. Collection was performed by two groups of investigators to avoid risk of bias. The Cochrane Collaboration's tool was used for assessing risk of bias. We identified human, in vivo , and in vitro research studies utilizing RFA for tumor tissues. We required that the studies included at least one of the following: complications, recurrence, or survival, and took interest to studies identifying cellular signaling pathway patterns after RFA. Descriptive statistical analysis was performed in 'R' software including mean and confidence interval., Results: The most frequent cancers studied were liver and lung cancers accounting for 57.4% (N=995) and 15.4% (N=267), followed by esophageal (N=190) and breast cancer (N=134). The most common reported complications were bleeding (19%) and post-operative pain (14%). In our literature search, four independent studies showed upregulation and activation of the VEGF pathway following RFA, four showed upregulation and activation of the AKT pathway following RFA, three studies demonstrated involvement of matrix metalloproteinases, and four showed upregulation of c-Met protein following RFA., Conclusions: In our review and meta-analysis, we identify several proteins and pathways of interest of which are important in wound healing, angiogenesis, and cellular growth and survival. These proteins and pathways of interest may implicate areas of research towards RFA resistance and cancer recurrence., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://gs.amegroups.com/article/view/10.21037/gs-22-555/coif).

Background: Primary hyperparathyroidism (pHPT) is an endocrine disorder typically characterized by elevated serum calcium and elevated parathyroid hormone (PTH). While parathyroidectomy is the standard treatment, non-operative intervention such as radiofrequency ablation (RFA) has been adopted as an alternative for the management of pHPT, as it has been utilized in other endocrine glands such as thyroid and adrenal. In this literature review, we aim to evaluate the current practice of RFA for pHPT., Methods: A systematic literature search using PubMed, Web of Science, and Embase through June 2022 was conducted. Studies included in the review consisted of patient cohorts who had an unequivocal diagnosis of pHPT and underwent the treatment of pHPT with RFA. When more than one study was published from a similar cohort of patients, only the study with the most number of patients was considered. Studies included were assessed for bias using the critical appraisal instruments from the Joanna Briggs Institute (JBI) System., Results: A total of 14 studies describing 167 parathyroid glands treated in 163 patients were reviewed. The overall cure rate was 91.2%, with 5 patients undergoing more than one ablation. The most common adverse effect encountered was temporary dysphonia. Incomplete ablation and missed multiglandular disease were the most common reasons for RFA treatment failure., Conclusions: RFA may be an effective and safe alternative to parathyroidectomy in select patients with a well-localized, well-located parathyroid adenoma. Additional long-term data are needed to refine its role in the pHPT treatment algorithm., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://gs.amegroups.com/article/view/10.21037/gs-22-546/coif).

Background: Despite extensive research on sex differences in primary thyroid cancer, there is a lack of data on the role of sex in the risk of developing second primary thyroid cancer (SPTC). We aimed to investigate the risk of SPTC development according to patient sex, with an emphasis concerning previous malignancy location as well as age., Methods: Cancer survivors diagnosed with SPTC were identified from the Surveillance, Epidemiology, and End Results (SEER) database. The SEER*Stat software package obtained standardized incidence ratios (SIR) and absolute excess risks of subsequent thyroid cancer development., Results: Data for 9,730 (62.3%) females and 5,890 (37.7%) males were extracted for a total of 15,620 SPTC individuals. Asian/Pacific Islanders had the highest incidence of SPTC [SIR =2.67, 95% confidence interval (CI): 2.49-2.86]. The risk of SPTC was higher in males (SIR =2.01, 95% CI: 1.94-2.08) than when compared to females (SIR =1.83, 95% CI: 1.79-1.88; P<0.001). Head and neck tumors had significantly higher SIRs for SPTC development in males when compared to females., Conclusions: Survivors of primary malignancies have an increased risk SPTC, especially males. Our work suggests that oncologists and endocrinologists may consider the need for increased surveillance of both male and female patients given their increased risk of SPTC., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://gs.amegroups.com/article/view/10.21037/gs-22-411/coif).

Background: Examining risk factors of readmission in adrenalectomy patients and estimated the cost burden of unplanned readmission on the United States' healthcare system., Methods: According to the Nationwide Readmission Database, 20,494 patients underwent adrenalectomy between 2010-2014. Demographics, comorbidities, clinical data, length of stay (LOS), annual case volume, and discharge disposition of 30- and 90-day readmission cohorts were compared to the non-readmitted cohort., Results: A total of 1,463 (7.9%) and 1,959 (12.7%) adrenalectomy patients were readmitted at 30 and 90 days after discharge, respectively. Prolonged initial hospital stays [odds ratio (OR) =1.93; 95% confidence interval (CI): 1.63-2.27] and postoperative complications (OR =4.91; 95% CI: 1.98-12.16) were associated with a higher risk of readmission. Complications were significantly more frequent in patients with a primary or secondary malignancy (OR =1.42; 95% CI: 1.23-1.64) and in patients undergoing a procedure at a low adrenalectomy volume hospital [hazard ratio (HR) =0.75; 95% CI: 0.62-0.91; P=0.003]. Readmission extended overall LOS by an average of 2.06 days, costing an additional $18,529.49 per admission., Conclusions: Readmission adds significantly to the burden of disease after adrenalectomy. Understanding contributing factors may identify strategies to reduce readmissions and improve healthcare for patients., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://gs.amegroups.com/article/view/10.21037/gs-22-18/coif).

Background: Diabetes is a significant and prevalent medical condition associated with increased comorbidities, longer hospital length of stay, and higher healthcare costs. We aimed to assess the association between diabetes mellitus and postoperative outcomes following pancreatic surgeries., Methods: Records for patients with major elective pancreatic surgeries were retrieved retrospectively from the Nationwide Readmission Database (2010-2014). Association of diabetic status with postoperative complications, in-hospital mortality, length of stay (LOS), readmission rate, and hospital costs were investigated. Logistic regression and decision tree analyses were employed to predict adverse outcomes., Results: A total of 8,401 patients who had pancreatic surgery were included. They were categorized according to their diabetic diagnosis. Results showed that diabetic patients had a higher risk of postoperative complications compared to non-diabetics (OR: 1.27, 95% CI: 1.08-1.49, P=0.003). Bleeding and renal complications were the most significant. Uncontrolled diabetes significantly required a longer hospital stay (9.17±4.28 vs. 8.03±4.96 days, P=0.001), and incurred higher hospital costs ($34,171.04±$20,846.61 vs. $28,182.21±$24,070.27, P=0.001). After multivariate regression, no association was found with in-hospital mortality or readmission rates; however, diabetic patients' length of stay during readmission was increased at 30- and 90-day readmissions (P=0.004 and 0.007, respectively)., Conclusions: Among patients who underwent pancreatic surgery, those with diabetes had a higher rate of postoperative complications compared to non-diabetics. Additionally, diabetic patients had higher hospital charges and costs during primary admission. Initial analysis of patients with diabetes showed they had higher rates of 30- and 90-day readmissions, though this did not maintain significance after regression analysis. Exploring the mechanisms underlying this finding would aid in preventing postoperative complications and reducing healthcare costs., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://gs.amegroups.com/article/view/10.21037/gs-21-648/coif).

Background: Hypoparathyroidism (HypoPT) is a common sequela of anterior neck surgeries. While the acute risks of HypoPT are well known, emerging evidence is beginning to define the risks chronic HypoPT poses to patients. This meta-analysis aims to evaluate that risk and give more insight into its consequences., Methods: A systematic review and meta-analysis were performed, searching EMBASE, Web of Science, and Scopus for studies published up to July 1, 2020 and reported following PRISMA guidelines. Pooled analysis was estimated using the Mantel-Haenszel method and a random-effects model. A sub-analysis of the pooled data for each morbidity was performed and demonstrated in forest plots., Results: Patients with postsurgical chronic HypoPT had a high risk of cardiac morbidities [odds ratio (OR) =1.43; 95% confidence interval (95% CI): 1.21 to 1.70; P<0.001] in the absence of elevated risk of cardiac arrhythmias (OR =1.35, 95% CI: 0.96 to 1.79, P=0.08). Analysis also showed higher odds of developing renal disease (OR =4.85, 95% CI: 3.54 to 6.67, P<0.001), renal stones (OR =3.86, 95% CI: 1.81 to 8.23, P<0.001), seizures (OR =2.41, 95% CI: 1.66 to 3.5, P<0.001), mental health problems (OR =1.46, 95% CI: 1.21 to 1.77, P<0.001), and infections (OR =1.51, 95% CI: 1.28 to 1.78, P<0.001). Conversely, HypoPT has no effect on mortality risk (OR =1.19, 95% CI: 0.96 to 1.49, P=0.12)., Conclusions: Postsurgical HypoPT patients are vulnerable to a variety of medical and psychiatric diseases. This meta-analysis should guide surgeons in preoperative counseling and postoperative care for patients undergoing anterior neck surgeries., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://dx.doi.org/10.21037/gs-21-181).

Background: Little is known about the implications of hyperthyroidism on cardiovascular diseases like myocardial infarctions (MI), ischemic strokes, and hemorrhagic strokes. Previous studies implicate hyperthyroidism as a risk factor for MI and ischemic stroke. Cardiovascular disease is the leading cause of death in the US, and the possibility of hyperthyroidism contributing to this disease burden warrants investigation in a US patient population., Methods: The National Readmission Database (NRD) from 2010 to 2017 was used to identify adults who had a new-onset diagnosis of MI, ischemic stroke, or hemorrhagic stroke. Risk factors for mortality, prolonged hospital stay, and hospital cost were analyzed with binary logistic regression., Results: A total of 278,609,748 hospital records were reviewed. Of these, 15,685,461 were hospitalized for adverse cardiovascular events with concomitant hyperthyroidism, roughly 4.5 per 1,000 cases. Patients with MI and hemorrhagic stroke with thyrotoxicosis had a lower mortality rate than euthyroid patients (OR 0.81, 95% CI: 0.78-0.84, P<0.001 and OR 0.72, 95% CI: 0.67-0.77, P<0.001, respectively). Thyrotoxicosis was associated with increased hospital stay (MI: OR 1.35, 95% CI: 1.32-1.38, P<0.001; ischemic: OR 1.38, 95% CI: 1.35-1.41, P<0.001; hemorrhagic: OR 1.33, 95% CI: 1.25-1.40, P<0.001), expenditures in ischemic (OR 1.31, 95% CI: 1.28-1.34, P<0.001) and hemorrhagic stroke patients (OR 1.18, 95% CI: 1.12-1.24, P<0.001)., Conclusions: Patients that experienced MI or hemorrhagic stroke with concomitant thyrotoxicosis were observed to have a lower mortality rate than euthyroid patients but had with an increased length of hospital stay. Patients who had ischemic or hemorrhagic stroke with thyrotoxicosis had a significantly higher hospital cost. The hyperdynamic state underlying hyperthyroidism may be protective in these adverse events.

Background: Undifferentiated thyroid cancer (UTC) accounts for only 1-2% of all thyroid cancers. UTC is one of the most aggressive solid tumors with high metastatic rates and mortality. The objectives of this study are to examine the characteristics of patients with UTC and their overall survival., Methods: Retrospective analysis utilizing the National Cancer Database, 2004-2014 is performed. The study population included adults (≥18 years) patients with UTC or differentiated thyroid carcinoma (DTC), which served as a reference group., Results: A total of 1,870 UTC and 209,707 DTC patients were identified. The median follow-up time of UTC patients was 3.9 months (interquartile range: 1.6-9.0 months). When compared to DTC patients, patients with UTC were more likely to be ≥45-year-old [OR: 48.62, 95% CI: (35.75, 66.14), P<0.001], male [OR: 2.02, 95% CI: (1.84, 2.22), P<0.001], and/or black [OR: 1.27, 95% CI: (1.08, 1.49), P=0.004]. UTC patients were more likely to have Medicaid/Medicare or no insurance and treated in low-volume hospitals (P<0.001). Overall survival in patients with UTC was lower in patients older than 65 years [OR: 1.63, 95% CI: (1.12, 2.38), P=0.011], with multiple comorbidities [OR: 1.65, 95% CI: (1.02, 2.67), P=0.040] and/or presented with metastatic disease [OR: 1.93, 95% CI: (1.71, 2.17), P<0.001]. Compared to thyroidectomy alone, patients without metastasis who received adjuvant radiotherapy and/or chemotherapy had a better overall survival (P<0.001 each). In patients with metastatic disease, any intervention or combination of interventions other than thyroidectomy alone improved survival (P<0.05)., Conclusions: Older age, male, and/or black are associated with a higher prevalence of UTC compared to DTC. Although overall survival is poor in UTC, utilization of multi-modal treatment may improve survival., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://dx.doi.org/10.21037/gs-20-927).

Background: There have been few reports of robotic-assisted transaxillary parathyroidectomy in the literature. We aim to report our experience with robotic-assisted transaxillary parathyroidectomy for primary hyperparathyroidism (PHPT) in the Western population., Methods: A retrospective study was performed from July 2010 through July 2019 at two institutions, one in the United States and one in France. Demographic characteristics and perioperative data were collected for all patients undergoing robotic-assisted transaxillary parathyroidectomy by a single surgeon at each institution. A linear regression model was developed to describe the learning curve for this procedure at each institution., Results: One-hundred and two patients with PHPT were included with a median age of 55.6±12.4 years and median body mass index (BMI) of 25.5±6.1 kg/m 2 . The majority of patients were female (80.4%). Median total operative time was 116±53 minutes. Minor complications were reported in 2 patients (1.96%), and one case was converted to a trans-cervical approach (TCA) for four-gland exploration. Median patient follow-up time was 6.5±12.2 months, and disease recurrence was reported in one patient. Calculated learning curves showed that one surgeon achieved proficiency by the eighth case, and the other achieved proficiency by the fourteenth case., Conclusions: This is the largest reported experience of robotic-assisted transaxillary parathyroidectomy for PHPT in the Asian and Western population. Analysis of the procedural learning curve demonstrates that proficiency in this technique was achieved after performance of less than 15 surgeries. This procedure is safe and feasible in the hands of experienced surgeons for select patients with localized disease., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at http://dx.doi.org/10.21037/gs-20-761).

Background: Patients and physicians are increasingly utilizing online video sharing sites such as YouTube for obtaining and disseminating health-related information in multimedia format; however, due to its free, open-access platform, YouTube videos fall short in providing validated, up-to-date medical information, and may even convey unintended messages to patients who are seeking additional information on surgeries. We evaluated the relevance, reliability, and quality of YouTube videos on novel surgical techniques in thyroid surgery., Methods: The top 50 indexed YouTube videos for the queries, "robotic thyroid surgery" and "transoral thyroid surgery", were assessed by two independent reviewers for video quality and reliability for patient understanding. Videos were scored using Global Quality Score (GQS), a scale for video quality, and DISCERN Scoring, a questionnaire for reliability and quality measures of information presented., Results: The mean ± standard deviation (SD) duration of the videos (n=50) was 8.1±3.7 minutes. Total views were 261,440 and the mean ± SD time since upload was 3.6±2.6 years. The median and interquartile range of video power index (VPI) was 1.9 (0.5-3.7), GQS was 3.0 (2.0-4.0), and DISCERN score was 2.8 (2.3-3.2). Most videos were uploaded by physicians (75.8%) and the highest number of videos (63.6%) uploaded were from the United States (US). Videos with higher quality and reliability scores were uploaded by academic professionals, and included videos of physicians who described procedural information, perioperative instructions, and possible postoperative complications (P<0.05). Adequate medical information on the procedure and discussion of complications in YouTube videos were independent predictors of advanced educational quality and reliability., Conclusions: Clinical information on new surgical techniques such as transoral and robotic thyroid surgeries in YouTube videos scored low on quality and reliability as a source of patient education. Physicians should provide supplemental educational material online and offline to aid patient understanding of novel procedures., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at http://dx.doi.org/10.21037/gs-20-734).

Background: Poor cosmesis, secondary to keloid or hypertrophic scar, following thyroid surgery may cause considerable patient distress and be a significant challenge to treat. In this case series we examined the efficacy of prophylactic external beam radiation therapy (EBRT) for prevention of keloid formation in keloid-prone patients undergoing thyroid surgery. While much has been published about documenting the efficacy in reducing keloid formation following keloid excision, very little literature exists documenting prophylactic use related to surgeries with the goal of prevent de novo keloid formation., Methods: We retrospectively evaluated a series of ten patients, who underwent a prophylactic EBRT for keloid prevention after thyroid surgery between January 2013 and February 2019. Patient demographics, primary diagnosis, surgical procedure, EBRT dosage, and post-operative visit records were reviewed., Results: All ten patients who received EBRT for keloid prophylaxis following a thyroid surgery were female. Half of the patients were African Americans, 40% Caucasians, and 10% Hispanic. The mean age was 46.40±15.63 years with BMI of 31.5±5.5 kg/m 2 . Radiation was initiated within 6 hours of the surgery with an average radiation dose per session of 5.7±1.7 Gy. The total average EBRT dose delivered was 17.4±4.2 Gy. Mean follow-up period was 13 months post-thyroidectomy, with the longest follow-up at 23 months. One patient, who underwent a lateral neck dissection in addition to thyroid surgery, developed hypertrophic scar in less than 10% of her incision length. Nine other patients (90%) showed no post-surgical keloid nor hypertrophic scar formation and patients were satisfied with postsurgical cosmesis., Conclusions: We examined the efficacy of prophylactic EBRT in keloid-prone patients undergoing thyroid surgery. Prophylactic EBRT following thyroid surgery is effective in achieving a satisfactory cosmetic outcome in patients at high risk for keloid formation., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at http://dx.doi.org/10.21037/gs-20-511).

Background: The objectives of the study is to examine the prevalence and burden of major structures injury (pharynx, esophagus, trachea, larynx, lymphatic, vessels & nerves) in patients who underwent thyroid, parathyroid, and neck dissection surgeries in the United States., Methods: The study is a retrospective cross-sectional analysis utilizing the Nationwide Readmissions Database, 2010-2015. The study population included adults (≥18 years) patients who underwent thyroid, parathyroid, and neck dissection surgeries., Results: A total of 54,443 patients were included. Major structures injury was reported in 221 (0.48%) patients. The injured structures were vascular (0.22%), lymphatic (0.18%), pharynx/esophagus (0.06%), neural (0.03%), and trachea/larynx (0.002%). The risk of injury increased annually during the study period (OR: 1.29, 95% CI: 1.16, 1.44, P<0.001). The risk of injury was highest in patients who underwent thyroidectomy with neck dissection (1.01%) or neck dissection alone (1.81%) (P<0.001 each). The risk was also highest for patients with a head and neck cancer diagnosis (OR: 1.80, 95% CI: 1.24, 2.61, P=0.002). Patients with those injuries had a higher prevalence of blood transfusion (2.82% vs. 0.17%), postoperative fistula (3.10% vs. 0.03%), readmission (28.90% vs. 3.59%), and postoperative mortality (0.87% vs. 0.06%) (P<0.05 each). Management of patients with those injuries was associated with a longer hospital stay by 4.86±0.48 days (P<0.001), and a higher cost by $16,151.00±173.36 (P<0.001)., Conclusions: Injuries of major structures in thyroid and neck surgeries are more prevalent in cancer patients. There has been a recent increase in the risk of such injuries in the United States. Those injuries are associated with significant clinical and economic burden., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form.

Background: Up to 30% of thyroid nodules undergoing fine needle aspiration (FNA) yield an indeterminate result. Recent research efforts have suggested that nuclear morphometry and morphology may enhance the diagnostic accuracy of FNA as an objective adjunct. We applied nuclear morphometric analysis on a diverse cohort of patients to evaluate the association between nuclear morphometry and malignancy., Methods: Forty-five randomly selected patients, who underwent thyroid surgery after an indeterminate FNA result (Bethesda III & IV) between 2012-2015, were reviewed. One hundred representative nuclei per FNA of a thyroid nodule were analyzed using ImageJ. Seven validated morphometric parameters were collected: nuclear area, perimeter, circularity, aspect ratio, roundness, and maximum/minimum Feret's diameter. L/S ratio was subsequently calculated. All 8 nuclear parameters were reported as averages with standard errors of the mean (SEM). A Student's t -test was used to assess the association of nuclear parameters with final surgical pathology., Results: The mean age of all patients was 56.31±15.39 years, with female patients comprising 68.9% of the cohort. Twenty-two patients had malignant thyroid nodules. The mean perimeter of nuclei for the cohort was 18.48±0.45 µm, the mean area was 22.19±0.93 µm, and the mean maximum Feret's diameter was 6.67±0.13 µm. No significant differences in the 8 nuclear parameters were observed between the malignant and non-malignant groups., Conclusions: In the population examined, our results suggest that nuclear morphometry is not yet a tool of reliable diagnostic value in accessing malignant and non-malignant thyroid nodules. Further investigation is necessary to identify objective parameters that will enhance diagnostic accuracy of indeterminate FNA cytology to minimize the number of diagnostic thyroid surgery., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at http://dx.doi.org/10.21037/gs.2020.02.02).

Background: The use of hemostatic agents in thyroid surgery has been widely reported in the literature. The aim of this study is to assess the safety and efficacy of hemostatic agents in comparison to conventional techniques for hemostasis by meta-analysis of the current literature., Methods: Articles were identified from PubMed and EMBASE using the following keyword searches: "hemostatic agent and thyroid surgery" and "hemostatic agent and thyroidectomy". Outcomes included total operative time, estimated blood loss, length of hospital stay, and intraoperative and postoperative complications. Data were extracted following review of appropriate studies by two independent authors and outcome differences were calculated using analysis of variance and the Bonferroni method., Results: Thirty-four publications were identified and 10 studies met our inclusion criteria, totaling 941 patients, 519 (55.1%) of which received a hemostatic agent during thyroid surgery. Of these patients who had hemostatic agents, 369 (71%) received a hemostatic gel and 150 (29%) received an oxidized cellulose patch. Outcome measures in each of these groups were compared with the patients receiving only conventional methods of hemostasis. The risk of hematoma formation in the hemostatic gel group was comparable to conventional hemostatic methods (95% CI: 0.33, 2.59). This was also true when comparing conventional hemostasis to the patch (95% CI: 0.64, 15.24). No difference in the risk for seroma formation was found between the conventional and hemostatic gel groups (95% CI: 0.26, 3.95). Drain output was significantly less in the gel group 40.75±35.6 mL compared to 66.26±31.2 mL in the conventional group (95% CI: -23.422, -7.460). Patients who received hemostatic agents had shorter hospital stays when compared to the conventional group (95% CI: -1.057, -0.203)., Conclusions: Our meta-analysis suggests that the use of a hemostatic agent in thyroid surgery yields minimal advantages for the management of perioperative bleeding risk., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Background: Resection is the only option for potential cure in pancreatic cancer. Patients admitted for resection may have the procedure deferred during their hospitalization. We aim to identify factors that lead pancreatic cancer patients to undergo resection., Methods: An analysis utilizing the Nationwide Inpatient Sample (NIS) database, 2003-2009. Study population included adults (≥18 years) with pancreatic cancer who underwent either pancreatic resection or other interventions. Surgeon volume classified based on the median into low and high-volume surgeon., Results: Eleven thousand three hundred and sixty-five patients were included; 68.0% underwent pancreatic resection, while 32.0% had other interventions. The majority of patients resected were <60 years old, female, with higher annual household income (P<0.05 for all). Patients with Medicaid coverage and comorbidity scores ≥2 were least likely to undergo pancreatic resection. Resection was more likely for high-volume surgeons, high-volume hospitals and teaching hospitals (P<0.05 for all). Those managed by high-volume surgeons were at a lower risk of postoperative complications, lower mortality, shorter hospital stay, and lower healthcare costs (P<0.05 for all)., Conclusions: Patients' insurance type and economic status are significantly associated with their ability to achieve pancreatic resection. Surgeon experience and hospital volumes were also significantly associated with pancreatic resection, clinical and economic outcomes., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Background: Numerous new approaches have been described over the years to improve the cosmetic outcomes of thyroid surgery. Transoral approach is a new technique that aims to achieve superior cosmetic outcomes by concealing the incision in the oral cavity., Methods: Transoral thyroidectomy through vestibular approach was performed in two institutions on cadaveric models. Procedure was performed endoscopically in one institution, while the robotic technique was utilized at the other., Results: Transoral thyroidectomy was successfully performed at both institutions with robotic and endoscopic techniques. All vital structures were identified and preserved., Conclusions: Transoral thyroidectomy has been performed in animal and cadaveric models, as well as in some clinical studies. Our initial experience indicates the feasibility of this approach. More clinical studies are required to elucidate its full utility., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

We recently reported on the safety and feasibility of robotic transaxillary approaches for parathyroid surgeries with benefit of avoiding a visible cervical scar. Herein, we demonstrate our technique with utilization of intraoperative nerve monitoring and indocyanine green (ICG) imaging. The patient was discharged a few hours after the surgery., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Background: Thyroid abnormalities have been found intraoperatively during parathyroidectomy and have resulted in concomitant thyroidectomy. The identification of concomitant disease is important prior to primary operation in order to minimize reoperations. This study investigates the incidence of concomitant primary hyperparathyroidism (PHPT) and thyroid nodular disease in patients undergoing thyroidectomy or parathyroidectomy., Methods: We performed a retrospective review of prospectively gathered data for 621 patients who underwent thyroidectomy, parathyroidectomy, or both at Tulane Medical Center. Information obtained included initial referral, initial thyroid stimulating hormone (TSH), initial parathyroid hormone (PTH), fine needle aspiration (FNA) results, ultrasound results, type of operation performed, final diagnosis, and final pathology., Results: Among the 400 patients referred primarily for thyroid disease, 13.50% underwent a thyroidectomy and parathyroidectomy (PTX) simultaneously and 10.75% received a final diagnosis of thyroid and concomitant parathyroid disease. Among the 103 patients referred primarily for parathyroid disease, 26.21% underwent a PTX and thyroidectomy and 24.27% received a final diagnosis of both thyroid and parathyroid disease. Patients referred primarily for parathyroid disease were more likely to receive a final diagnosis of both parathyroid and thyroid disease and were more likely to undergo a combined operation., Conclusions: Concomitant thyroid and parathyroid disease occur and preoperative analysis is important to avoid increased complications from reoperations., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Background: Performance of thyroid surgery as a same day surgery procedure has been a controversial topic. This study aimed to compare the safety and efficacy of outpatient thyroid surgery with inpatient thyroid surgery by meta-analysis of current literature., Methods: Articles were identified from the following keyword searches: outpatient thyroidectomy/thyroid surgery, same day thyroidectomy/thyroid surgery. Outcomes included perioperative complications including recurrent laryngeal nerve (RLN) injury, hypocalcemia, and readmissions. Data were extracted following review of appropriate studies by authors and random effects models were used., Results: 34 potentially relevant publications were identified and 14 studies fulfilled the predetermined inclusion criteria, totaling 10,478 patients, 4,565 of whom were discharged the same day following thyroid surgery. There was no difference in malignancy rate between the two groups (95% CI, 0.84-2.31; P=0.196). Inpatient group were 2.23 times (95% CI, 1.36-3.36; P=0.001) more likely to develop transient RLN injury and 2.32 times (95% CI, 1.06-5.06; P=0.034) more likely to have documented transient hypocalcemia compared to outpatients. Inpatient groups were 2.10 times (95% CI, 1.33-3.33; P=0.002) more likely to have documented other complications. The two groups also had similar readmission rates (95% CI, 0.71-1.41; P=1.000)., Conclusions: Our meta-analysis suggests that discharging selective patients the same day after a thyroid surgery is as safe, feasible, and efficacious as admitting them for observation. Admitting patients after thyroid surgery is associated with higher reported risk of complications., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Robot assisted thyroid surgery has the advantage of a superior field vision and technical advancements of robotic technology that have permitted novel remote access thyroid surgical approaches. Gasless trans-axillary robot-assisted thyroidectomy has been proved to be among the most current feasible approaches. This approach offers an excellent cosmetic outcome, with comparable outcomes to conventional surgical approaches. This review aims to provide details of this specific remote access technique for thyroid resection with most recent evidences in the literature., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Surgery is the gold standard treatment for patients with thyroid cancer or nodules suspicious for cancer. Open conventional approach is the standard surgical approach. However, a visible neck incision could be a concern for most young female patients, especially for patients with a history of healing with keloid or hypertrophic scars. Robotic remote access approaches have evolved into a safe and feasible approach in selected patients, providing a hidden scar with good patient satisfaction. This review will focus on the performance and safety of robotic retroauricular thyroid surgery., Competing Interests: The authors have no conflicts of interest to declare.

Background: Several reports have proposed that increased vascular flow on color Doppler sonography may be associated with malignancy in thyroid nodules. Others have described no correlation between the presence of flow and risk of malignancy. The purpose of this study was to determine whether the vascularity of a thyroid nodule can aid in the prediction of malignancy by performing a meta-analysis of the current literature., Methods: Independent reviewers conducted a systematic review of publications from PubMed, EMBASE, and the Cochrane Database of Systematic Review using the following keyword searches: "vascular thyroid nodule", and "vascular malignant thyroid nodule". Outcomes included vascular flow pattern, nodule size, calcifications, echogenicity, margins, and shape. Data were extracted following review of appropriate studies, and outcome differences were calculated using analysis of variance and the Bonferroni method., Results: Eighty-nine publications were identified and 14 prospective studies met inclusion criteria totaling 4,154 thyroid nodules, 1,419 (34%) of which were malignant. Thirty-three percent of malignant thyroid nodules had no vascular flow, while 17% had peripheral and 50% had internal vascular flow. There was no significant difference in vascular flow (95% CI: -14.329, 4.257), or peripheral vascular flow rate between malignant and benign thyroid nodules (95% CI: -29.254, 4.313). Also, there was no significant difference in internal vascularity between malignant and benign thyroid nodules (95% CI: -72.067, 2.824)., Conclusions: It appears that utilization of vascular flow on color Doppler sonography may not accurately predict malignancy in thyroid nodules. Further studies are warranted to investigate the predictive role of increased vascularity in diagnosing suspicious thyroid nodules., Competing Interests: The authors have no conflicts of interest to declare.

Background: Fine needle aspiration (FNA) can lead to changes that extensively replace cytological confirmed thyroid lesions. These lesions, so called "vanishing tumors" can be diagnostically challenging to pathologists and therapeutically challenging for endocrinologists and surgeons. We performed a retrospective analysis to identify these tumors., Methods: Data of 656 patients referred for thyroid surgery was reviewed. Patients with suspicious lesions on neck ultrasound (US) underwent FNA. We compared FNA cytological and surgical pathological findings to identify vanishing tumors. FNA-induced changes such as cystic degeneration, hemorrhage, calcification, cholesterol crystals, fibrosis and granulation tissue were identified., Results: Seventeen patients (2.5%) were identified with vanishing tumors. FNA cytology was indeterminate in seven (41.1%) and benign in ten (58.8%) patients. Surgical pathology in all nodules showed regressive changes partially or entirely replacing the tumor. The mean size of vanishing tumors was 2.4±1.5 cm in greatest dimension. Seven nodules (41.1%) were entirely replaced while remaining ten nodules showed partial replacement of tumors. Three (17.6%) nodules had focal areas of optically clear nuclei suspicious of papillary thyroid carcinoma (PTC); one showed an additional focus of follicular neoplasm (FN) of uncertain malignant potential., Conclusions: FNA-induced changes can lead to obliteration of nodules rendering pathological diagnosis with no evidence of confirmed lesions. Pathologists and surgeons should be aware of this challenging scenario.

Background: Tumor size is recognized as an important predictor of malignancy in many types of cancers. However, there is no clear line of characterization when it comes to the association between thyroid nodule size and malignancy risk prediction; and the current data remains inconsistent across different studies. The aim of our study is to examine the association between nodule size and malignancy using meta-analysis of the current literature., Methods: Data sources were gathered through systemic search of PubMed, Embase and other scientific databases for articles published between January 1, 1996 and June 1, 2013. A reference group with nodule sizes <3 cm was set as a control group. Two other nodule size categories were established and these included nodules from 3-5.9 cm and nodules ≥6 cm in size. Primary outcome was a histologically proven malignancy per nodule size category. The effect sizes of clinicopathologic parameters, which are the quantitative measures of association strength between two variables, were calculated by the means of odds ratios (OR). The effect sizes were then combined using a random-effects model., Results: Seven studies met our inclusion criteria with 10,817 thyroid nodules evaluated. Malignancy was identified in 2,206 (20.4%) nodules. After adjusting for patient age and gender, nodules that measured 3-5.9 cm had a 26% greater malignancy risk compared to those measuring <3 cm [OR, 1.26; 95% confidence interval (CI): 1.13-1.39]. However, nodules 6 cm or larger had a 16% lower risk of malignancy compared to those measuring <3 cm (OR, 0.84; 95% CI: 0.73-0.98)., Conclusions: Thyroid nodule size predicts cancer risk. However, a threshold effect of thyroid nodule size 6 cm or greater is significantly associated with a more benign disease.

Recurrent laryngeal nerve (RLN) injury is one of the most common complications of thyroid surgery. RLN injury can cause vocal cord paralysis, affecting the patient's voice and the quality of life. Injury of the external branch of the superior laryngeal nerve (EBSLN) can cause cricothyroid muscle denervation affecting high vocal tones. Thus, securing the laryngeal nerves in these surgeries is of utmost importance. Visual identification of the nerves has long been the standard method for this precaution. Intraoperative neuromonitoring (IONM) has been introduced as a novel technology to improve the protection of the laryngeal nerves and reduce the rate of RLN injury. The aim of this article is to provide a brief description of the technique and review the literature to illustrate the value of IONM. IONM can provide early identification of anatomical variations and unusual nerve routes, which carry a higher risk of injury if not detected. IONM helps in prognosticating postoperative nerve function. Moreover, by detecting nerve injury intraoperatively, it aids in staging bilateral surgeries to avoid bilateral vocal cord paralysis and tracheostomy. The article will discuss the value of continuous IONM (C-IOMN) that may prevent nerve injury by detecting EMG waveform changes indicating impending nerve injury. Herein, we are also discussing anatomy of laryngeal nerves and aspects of its injury.

Liver is the commonest site for metastasis in patients with neuroendocrine tumors (NETs); it occurs in 45-95% of patients. Available treatment options include surgical resection, liver transplantation, chemotherapy and biotherapy. Surgery is the gold standard for curative therapy. Typically, a multidisciplinary approach is a cornerstone for decision making while dealing with this aggressive disease. This review will focus on the performance and safety of open, laparoscopic, and liver transplant surgical approaches in NETs patients with liver metastases.

Current advancement in robotic surgery has provided a safe, precise, 3-dimensional (3D) magnified dissection for parathyroid surgery without the need for CO2 insufflation, and with a better cosmetic outcome due to an invisible scar in the axillary or retroauricular region. Preoperative imaging studies that assist in the localization of lesions have been key elements in patients' selection for targeted parathyroid surgery.

The patient was referred for management of a left adrenal incidentaloma. Preoperative CT scan and MRI showed focal calcification. Here we are presenting this video demonstrating robotic-assisted laparoscopic adrenalectomy for left adrenal mass.

Robot assisted thyroid surgery has been the latest advance in the evolution of thyroid surgery after endoscopy assisted procedures. The advantage of a superior field vision and technical advancements of robotic technology have permitted novel remote access (trans-axillary and retro-auricular) surgical approaches. Interestingly, several remote access surgical ports using robot surgical system and endoscopic technique have been customized to avoid the social stigma of a visible scar. Current literature has displayed their various advantages in terms of post-operative outcomes; however, the associated financial burden and also additional training and expertise necessary hinder its widespread adoption into endocrine surgery practices. These approaches offer excellent cosmesis, with a shorter learning curve and reduce discomfort to surgeons operating ergonomically through a robotic console. This review aims to provide details of various remote access techniques that are being offered for thyroid resection. Though these have been reported to be safe and feasible approaches for thyroid surgery, further evaluation for their efficacy still remains.

Background: Comprehensive neck ultrasound (US) examination has become an essential component of preoperative workup for patients with thyroid cancer. Regional cervical lymph nodes may be involved in cases of Hashimoto's thyroiditis (HT). This study seeks to examine the sonographic pattern of lymph nodes in patients with HT., Methods: This is a retrospective study looking at patients with confirmed diagnoses of HT on final surgical pathology who underwent preoperative comprehensive neck US. We compared preoperative ultrasound for patients with HT to euthyroid patients with goiter. Data collected included number, size and ultrasonographic features of cervical lymph nodes., Results: We included a total of 417 patients: 202 patients with HT in the study group, and 215 patients with goiter and euthyroid status in the control group. Patients with HT had a higher number of total cervical lymph nodes than the control group (2.00±2.35 vs. 0.76±1.36 mm; P<0.0001), most notably in cervical levels III and IV (P<0.05 for both)., Conclusions: HT seems to be associated with an ultrasonographic pattern of increased number of enlarged cervical lymph nodes, particularly in levels III, and IV.
