Abstract
Background: We assessed the prevalence of complications from percutaneous ethanol injection (PEI) for benign and cystic thyroid nodules (CTNs) and their management. Methods: We conducted a systematic review with meta-analysis of data from published observational studies on PEI of CTNs. We also included unpublished retrospectively collected data on complications after PEI from all consecutive patients with cytologically benign CTNs who underwent PEI at the Unit of Endocrinology and Metabolic Diseases, AOU University of Campania Luigi Vanvitelli (Naples, Italy) between June 1, 2021, and March 31, 2024. A random effects meta-analysis was performed on the prevalence rate data. Pooled prevalence data were presented with confidence intervals (CIs). The I2 statistic index was used to quantify the heterogeneity. The details of the complications and the management were qualitatively described. Results: The literature search yielded 1189 studies, of which 48 studies were included in the systematic review and meta-analysis, in addition to our institutional experience (3670 CTNs in total). The overall quality of each included study was judged as fair. The prevalence of "Overall" complications of PEI was 32% ([CI 25-40%], I2 92.7%, 967 of 3195 thyroid nodules [TNs]). The prevalence of "Minor" complications of PEI was 32% ([CI 25-40%], I2 92.7%, 952 of 3195 TNs). The prevalence of "Major" complications of PEI was 2% ([CI 1-2%], I2 0%, 22 of 3670 TNs). Sensitivity analyses did not modify the results. The pooled prevalence rate of local pain was 21% (CI [16-27] I2 90.3). Local pain was typically transient and mild, sometimes moderate, and requiring analgesics for few days. The pooled prevalence rate of dysphonia was 1% (CI [1-2], I2 0). Dysphonia was transient and could last from several hours to 12 months after PEI. Conclusions: Complications of PEI for benign and CTNs are relatively common, but most are minor and usually transient, not requiring treatment. Dysphonia was a major complication, but it was uncommon and transient. PEI for CTNs could be considered a generally safe technique.

The Comparison of Efficacy and Safety between Radiofrequency Ablation Alone and Ethanol Ablation Followed by Radiofrequency Ablation in the Treatment of Mixed Cystic and Solid Thyroid Nodule. JOURNAL OF THE KOREAN SOCIETY OF RADIOLOGY 2024; 85:618-630. [PMID: 38873386 PMCID: PMC11166582 DOI: 10.3348/jksr.2023.0056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 06/15/2023] [Accepted: 08/10/2023] [Indexed: 06/15/2024]
Abstract
Purpose To compare the efficacy and safety of radiofrequency ablation (RFA) and ethanol ablation (EA) followed by RFA in treating mixed cystic and solid thyroid nodules. Materials and Methods We included 243 nodules from 243 patients who underwent RFA for mixed cystic and solid benign nodules. The nodules were divided into two groups (RFA alone and EA + RFA). We evaluated volume reduction rate (VRR), therapeutic success rate, improvement in symptomatic and cosmetic issues, complications, and adverse effects. Results The RFA group included 204 patients, and the EA + RFA group included 39 patients. The long-term success rates in the RFA only and EA + RFA groups were 90.2% and 97.4%, respectively. The mean VRR at the last follow-up in the RFA and EA + RFA groups were 81.6% and 87.2%, respectively. Therapeutic results were similar in both groups at the last follow-up. Cosmetic and symptomatic problems markedly improved in both groups. No major complications were observed. Conclusion Both RFA alone and EA + RA are safe and effective methods for treating mixed cystic and solid thyroid nodules, although EA + RFA is slightly more effective.

Abstract
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.

Abstract
PURPOSE This study compared ethanol ablation (EA) with the Sistrunk operation (SO) with regard to feasibility, treatment efficacy, and cost-effectiveness. The goal was to evaluate whether EA could replace SO as a primary treatment modality for thyroglossal duct cysts (TGDCs). METHODS This retrospective case-control study included patients with TGDCs who were treated with either EA or SO between 2016 and 2022. The primary outcome variables evaluated were treatment efficacy (as measured by the volume reduction rate [VRR] and treatment success rate), complications, and cost-effectiveness. RESULTS A total of 72 patients were enrolled, with 33 in the EA group and 39 in the SO group. The procedure or operation times for the EA and SO groups were 9 and 82 minutes, respectively (P<0.001). At the final follow-up appointment, the VRR was 94.1% for the EA group and 100.0% for the SO group (P<0.001). Treatment success was achieved for 32 patients (97.0%) in the EA group and for all 39 patients (100.0%) in the SO group (P=0.458). The overall complication rates were 0.0% and 17.9% in the EA and SO groups, respectively (P=0.013). The total costs, including all treatment procedures and follow-up ultrasound examinations, were $485 and $1,081.7 for the EA and SO groups, respectively (P<0.001). CONCLUSION EA demonstrates superiority over SO in terms of feasibility, safety, and costeffectiveness, while maintaining comparable treatment efficacy. Despite the need for multiple treatment sessions in approximately one-quarter of patients, EA can serve as a primary treatment modality for selected patients with TGDCs, supplanting SO.

Abstract
Ultrasound-guided ablation techniques have been increasingly introduced into routine treatment of thyroid lesions as a complement to existing surgical therapies and radioiodine treatment. In cystic or predominantly cystic lesions instillation therapy (ethanol/polidocanol ablation) has yielded good results. Novel thermal ablation techniques, including radiofrequency ablation (RFA), microwave ablation (MWA), laser ablation (LA) and high intensity focused ultrasound (HIFU), induce irreversible cellular effects by locally applying temperatures ≥ 60 °C to the targeted thyroid region. Lesions causing local symptoms or focal hyperfunctionality can thus be selectively treated under continuous sonographic monitoring. While a considerable body of evidence supports the efficacy and safety of various local ablative techniques, future challenges lie in initiating comparative prospective trials and in standardizing clinical practice, training and continuous quality assessment on a regional and superregional level. In the future, it shall be indicated to include local ablative techniques - so far not known to all patients in Germany - into the informed decision-making process as a suitable alternative or supplement to existing therapies.

Abstract
The thyroglossal duct cyst (TGDC) is the most common congenital neck mass, accounting for 70-75% of all congenital neck masses. Although the Sistrunk operation has been used as a standard of treatment, it is accompanied by a considerable surgical burden, including the need for general anesthesia, a visible surgical scar on the neck surface, and postoperative complications. Ultrasound-guided ethanol ablation (US-EA) is a minimally invasive and office-based technique that is widely used as a non-surgical treatment for several benign cystic lesions, particularly benign thyroid cysts. Recently, US-EA has also been gaining popularity as a good alternative for TGDC treatment, which is associated with high feasibility, a high safety profile, and favorable treatment outcomes. To our best knowledge, seven studies on the use of EA as a primary treatment option for TGDC have been published since 2011. Although these studies have reported promising results, there is a lack of consensus on several issues regarding the application of EA for TGDC, particularly its detailed techniques and role as a primary treatment. This article aims to provide a comprehensive review of EA for TGDC, addressing technical issues and its possible role as a new standard of treatment for TGDC.

Abstract
Objective The aim of this study is to identify risk factors of intra-cystic hemorrhage in microwave ablation of mixed solid and cystic microwave ablation s, and to design a preoperative nomogram to predict the risk value of intraoperative bleeding with the goal of individualizing the surgical approach toward different types of cystic and solid thyroid nodules. Methods A total of 241 patients with cystic-solid thyroid nodules who underwent ultrasound-guided percutaneous microwave ablation were retrospectively divided into a bleeding group and a non-bleeding group to compare the diameter, cystic proportion, cystic fluid nature, color Doppler flow imaging, Contrast-enhanced ultrasound (CEUS) findings, and operative methods. Based on univariate and multivariate analysis, the important risk factors of nodular intracapsular hemorrhage in the ablation procedure were projected to a nomogram for predicting the possibility of intraoperative hemorrhage in the thyroid cystic solid nodules. Results Intra-cystic hemorrhage was developed in 37 cases during the ablation of mixed thyroid nodules with a total incidence of 15% (37/241). Significant differences were found statistically between the two groups on the diameter of the lesions, CEUS findings, the cystic fluid ratio, and operative methods (P = 0.000, P = 0.001, P = 0.024, P = 0.002). The possibility of intraoperative nodular intracapsular hemorrhage was predicted by the model based on the risk factors with the accuracy of 81% and prediction consistency index (C-index) of 0.78. Conclusion A new and efficient prediction model was developed based on the identified risk factors for intracapsular hemorrhage during microwave ablation of mixed thyroid nodules, which will aid in the development of targeted surgical planning for different types of cystic thyroid nodules, thus reducing the risk of hemorrhage during ablation.

Abstract
Objective This study aims to compare 1-month's efficacy and safety of single-session ethanol ablation and radiofrequency ablation for treating both purely cystic nodules and predominantly cystic thyroid nodules. Materials and methods This short-term retrospective study was approved by the Ethics Committee of the Institutional Review Board of Danang Family hospital, and written informed consent for procedures was obtained for all patients. Thirty-nine patients who presented with cystic thyroid nodules and met inclusion criteria were extracted from the computerized medical records. The internal fluid of cystic thyroid nodules was aspirated as much as possible. Ethanol ablation was performed using 18-gauge needles with 99.5% ethanol, and RFA used a cooled-electrode RFA system and 18-gauge internally cooled electrodes via the trans-isthmic approach, moving-shot technique. Nodule volume, therapeutic success rate, the largest diameter, thyroid function tests, and complications were evaluated and compared before and after treatment in each group. Results Among 39 patients, 17 patients were undergone EA (mean age of 47.35 years; the proportion of female of 76.5%; purely thyroid cyst percentage of 41.4%) and 22 patients were undergone RFA (mean age of 46.63 years; the proportion of female of 86.4%; purely thyroid cyst percentage of 54.5%). Both treatment techniques showed a significant reduction of the largest diameter and nodule volume (p<0.05) without complications. RFA reduced nodule volume and the largest nodule size greater than EA treatment at 1-month post-ablation (p<0.05). In addition, the therapeutic success rate in the RFA group was higher than in the EA group. Conclusion Both RFA and EA treatment with single-session confirm the efficacy and safety for cystic thyroid nodules at 1-month follow-up, RFA reduced greater in nodule volume and the largest nodule size than the EA treatment. Thus, the therapeutic success rate in the RFA group was higher than in the EA group.

Abstract
OBJECTIVE The objective of this disease state clinical review is to provide clinicians with a summary of the nonsurgical, minimally invasive approaches to managing thyroid nodules/malignancy, including their indications, efficacy, side effects, and outcomes. METHODS A literature search was conducted using PubMed and appropriate key words. Relevant publications on minimally invasive thyroid techniques were used to create this clinical review. RESULTS Minimally invasive thyroid techniques are effective and safe when performed by experienced centers. To date, percutaneous ethanol injection therapy is recommended for recurrent benign thyroid cysts. Both ultrasound-guided laser and radiofrequency ablation can be safely used for symptomatic solid nodules, both toxic and nontoxic. Microwave ablation and high-intensity focused ultrasound are newer approaches that need further clinical evaluation. Despite limited data, encouraging results suggest that minimally invasive techniques can also be used in small-size primary and locally recurrent thyroid cancer. CONCLUSION Surgery and radioiodine treatment remain the conventional and established treatments for nodular goiters. However, the new image-guided minimally invasive approaches appear safe and effective alternatives when used appropriately and by trained professionals to treat symptomatic or enlarging thyroid masses.

Abstract
BACKGROUND Percutaneous ethanol injection (PEI) is used for the treatment of benign cystic thyroid nodules. This systematic review and meta-analysis aimed to obtain strong evidence of its long-term efficacy and safety. METHODS PubMed, CENTRAL, Scopus and Web of Science databases were searched until November 2020 for studies reporting data on volume reduction rate (VRR), compressive symptoms and cosmetic concerns. Associated complications were assessed. A random-effects model was designed to pool the data. RESULTS Out of 385 papers, nine studies evaluating 1667 nodules were finally included. Overall, VRR at 6, 12, 24, 36, 60 and 120 months was 77%, 81%, 72%, 68%, 74% and 69%, respectively. Significant reductions in the compressive symptoms and cosmetic concerns were observed. No permanent complications were observed. CONCLUSIONS The present meta-analysis showed that PEI could significantly reduce the volume of benign cystic thyroid nodules. This reduction was already effective at 6 months post-treatment, and the effect was stable over time.

BACKGROUND The use of ultrasound-guided ablation procedures to treat both benign and malignant thyroid conditions is gaining increasing interest. This document has been developed as an international interdisciplinary evidence-based statement with a primary focus on radiofrequency ablation and is intended to serve as a manual for best practice application of ablation technologies. METHODS A comprehensive literature review was conducted to guide statement development and generation of best practice recommendations. Modified Delphi method was applied to assess whether statements met consensus among the entire author panel. RESULTS A review of the current state of ultrasound-guided ablation procedures for the treatment of benign and malignant thyroid conditions is presented. Eighteen best practice recommendations in topic areas of preprocedural evaluation, technique, postprocedural management, efficacy, potential complications, and implementation are provided. CONCLUSIONS As ultrasound-guided ablation procedures are increasingly utilized in benign and malignant thyroid disease, evidence-based and thoughtful application of best practices is warranted.

Abstract
A 7-year-old neutered male alpaca (Vicugna pacos) was presented for evaluation of a 3-year history of large, bilateral, firm ventral cervical masses causing esophageal and tracheal impingement. Ultrasound examination, radiographic evaluation, histopathological findings, and magnetic resonance imaging confirmed the masses to be bilateral thyroid adenomas. Conservative medical treatment by unilateral chemical ablation, using 10% formalin by aspiration technique, was performed on the left mass. Chemical ablation proved to be effective in decreasing the size of the mass, with no apparent adverse effects. To our knowledge, this case is the first known report of bilateral thyroid adenomas in an alpaca, a condition previously described in humans, horses, dogs, and cats.

Abstract
BACKGROUND A minimally invasive approach has been adopted to treat benign cystic nodules in recent years, with ethanol ablation (EA) being used as a more common method in routine treatment. For this study, we aimed to investigate the change of nodule volumes and cosmetic scores before and after EA in benign thyroid nodules and the effectiveness of treatment. Therefore, ultrasound data and cosmetic scores of pure cystic, mixed-type and spongy-type benign thyroid nodules undergoing EA in the last two years were reviewed retrospectively. METHODS Archive scanning was performed for all cases that were proven benign by fine-needle aspiration biopsy (FNAB) and who underwent EA. In all 46 patients included in the study, thyroid FNAB was performed. Ultrasound images were available to assess the size and volumes at pretreatment and 3 and 6 months after EA. The cosmetic scores obtained before the procedure and at 6 months after EA were compared. RESULTS There was a statistically significant difference when the sizes and volumes of the nodules were compared at pretreatment, 3 and 6 months follow-up (P < .001). The mean pretreatment cosmetic score was 3.09, and at 6 months, it was 1.20, with a statistically significant difference (P < .001). CONCLUSIONS Recently, a minimally invasive approach has been adopted in the treatment of benign cystic nodules, with ethanol ablation becoming more common in routine treatment. Therefore, ethanol ablation is very valuable in minimising complications that may arise from surgery.

Assessment of thyroid-specific quality of life in patients with benign symptomatic thyroid nodules treated with radiofrequency or ethanol ablation: a prospective multicenter study. Ultrasonography 2021; 41:204-211. [PMID: 34517695 PMCID: PMC8696143 DOI: 10.14366/usg.21003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Accepted: 06/29/2021] [Indexed: 11/18/2022] Open
Abstract
Purpose Radiofrequency ablation (RFA) and ethanol ablation (EA) are effective and safe for benign symptomatic thyroid nodules (BSTNs). However, relatively little is known about the effects of these procedures on patients’ quality of life (QoL). This prospective, multicenter study evaluated the effects of RFA and EA on changes in thyroid-specific QoL in patients with BSTNs and assessed the volume reduction and safety of these procedures. Methods Eighty-six consecutive patients with 86 BSTNs were prospectively included from two medical centers. RFA was performed for 55 BSTNs with solidity ≥50% and EA was performed for 31 BSTNs with solidity <50%. QoL was evaluated using an 11-scale, multiple-choice thyroid-specific QoL questionnaire. Nodule characteristics and QoL were evaluated at diagnosis and 1, 6, and 12 months after treatment. Overall QoL was rated from 0 (good) to 4 (poor). Results The mean longest size and volume of the index nodule were 4.2±1.5 cm and 21.6±22.1 mL, respectively. Patients received 1.1 treatments on average (range, 1 to 2). Significant post-treatment volume reductions were noted; however, the EA group showed a higher volume reduction than the RFA group at 1 (78.7%-16.1% vs. 49.1%-15.8%), 6 (86.3%-21.7% vs. 73.0%-14.5%), and 12 (90.9%-14.9% vs. 80.3%-12.4%) months. The score for each scale of the QoL questionnaire improved significantly during follow-up (all P<0.001). Overall QoL improved significantly, from 1.7±0.9 at diagnosis to 0.6±0.7 at the 12-month follow-up (P<0.001). There were no major complications. Conclusion Both RFA and EA are safe and effective in reducing nodule volume and improving thyroid-specific QoL in patients with BSTNs.

Chemical ablation using ethanol or OK-432 for the treatment of thyroglossal duct cysts: a systematic review and meta-analysis. Eur Radiol 2021; 31:9048-9056. [PMID: 34003346 DOI: 10.1007/s00330-021-08033-2] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Revised: 04/21/2021] [Accepted: 04/30/2021] [Indexed: 10/21/2022]
Abstract
OBJECTIVES To review the effectiveness and safety of chemical ablation using ethanol or OK-432 for the treatment of TGDCs (thyroglossal duct cysts). METHODS MEDLINE and EMBASE databases were searched up to May 29, 2020, to identify studies reporting the safety and efficacy of chemical ablation using ethanol or OK-432 for the treatment of TGDCs. The search query consisted of synonyms of thyroglossal duct cysts and ethanol or OK-432 ablation. The pooled success and complication rates were calculated using the inverse variance method to calculate weights, and pooled proportions were determined using the DerSimonian-Laird random-effects method. RESULTS Seven original articles including a total of 129 patients were included. The efficacy of chemical ablation was acceptable, with a pooled success rate of 70% (95% CI, 47-86%). The pooled success rate of ethanol ablation was superior to that of OK-432 ablation, although with equivocal statistical significance (84% vs. 51%, p = 0.055). Repeat ethanol ablation achieved a pooled success rate of 47% (95% CI, 24-71%). The chemical ablation procedures were safe, with a pooled major complication rate of 0.9% (95% CI, 0.1-5.8%). CONCLUSIONS Chemical ablation using ethanol or OK-432 for the treatment of TGDCs had acceptable success and low complication rates, and repeat treatment after initial failure was also feasible. In addition, it is an inexpensive and simple procedure and could therefore be considered a first-line treatment for TGDCs. KEY POINTS • The efficacy of chemical ablation using ethanol or OK-432 was acceptable, with a pooled success rate of 70% (95% CI, 47-86%). The pooled success rate of ethanol ablation was superior to that of OK-432 ablation, although with equivocal statistical significance (84% vs. 51%, p = 0.055). • Repeat ethanol ablation was also feasible, with a pooled success rate of 47% (95% CI, 24-71%). • The chemical ablation procedures were safe, with a pooled major complication rate of 0.9% (95% CI, 0.1-5.8%).

Abstract
PURPOSE The purpose of this study was to evaluate thyroglossal duct cyst (TGDC) volumes before and after treatment with ultrasound (US) in patients who underwent ethanol ablation (EA). Besides, the usability of cosmetic scoring in TGDC cases was investigated by comparing cosmetic scores pre-treatment and after EA. MATERIALS AND METHODS 28 TGDC cases who had EA in one session and had complete US data and cosmetic scores were included in the study. US data including TGDC diameters and volumes obtained at the pre-treatment, 3rd, 6th, and 12th month after EA were noted, respectively. Cosmetic scoring was performed pre-treatment and after EA using the WHO grading system simultaneously with US. RESULTS At the 12th month after EA, there was 85.2% reduction in mean diameter and 95.1% reduction in mean volume in TGDC cases (p < 0.001). The mean cosmetic score pre-treatment was 2.7 ± 0.8 and the mean cosmetic score at the 12th month was 1 (p < 0.001). When the changes in TGDC volumes and cosmetic scoring after EA were compared according to gender and age, there was no statistically significant difference (p > 0.05). CONCLUSION The current study demonstrated that EA can be used safely to reduce TGDC sizes and is an alternative treatment option to surgery.

Abstract
AIM To evaluate the long-term efficacy of percutaneous ethanol injection treatment (PEIT) as an alternative to thyroid surgery in symptomatic thyroid cysts. PATIENTS AND METHODS 100 subjects (48±12 years; 58% women) with symptomatic thyroid cysts relapsing after drainage were prospectively included. PEIT was conducted using an established procedure, and the initial cyst volume, symptoms and pain perceived by the patient were assessed. The volume of instilled alcohol was ≤2ml without re-extraction in all cases. Patients were followed-up for more than 3 years and final cyst volume and symptom improvement were assessed. RESULTS Mean maximum cyst diameter before drainage was 3.1±1.2cm. In 71% of patients ≤2 PEIT sessions were required. Median maximum cyst volume was 12.7 (5.4-21.7)ml before the first drainage and median total volume extracted from the cysts was 13.0 (6.2-37.0)ml. After a mean follow-up period of 52±10 months, 98% of patients reported a complete absence of symptoms. The final median volume for the whole group was 0.8 (0.1-2.0)ml with a median volume reduction of 94 (81-99)%. A final volume reduction greater than 65% was observed in 90% of cases. Reported pain during the procedure was absent or mild in 76.4% of cases. CONCLUSIONS PEIT is a safe and well-tolerated first-line treatment for symptomatic thyroid cysts with long-term effectiveness.

Abstract
BACKGROUND Ultrasound-guided minimally invasive procedures are widely used to treat thyroid diseases. The objective of this study was to assess the efficacy and safety of ethanol ablation (EA) in comparison with other non-surgical options in the treatment of benign thyroid cystic nodules. METHODS We conducted a systematic search of studies on EA for thyroid cystic nodules, mainly in the Ovid-MEDLINE and Embase, Web of Science, and Cochrane databases. The standardized mean difference (SMD) of the volume reduction ratio (VRR) after EA versus other non-surgical treatments comprised the primary outcome, whereas the odds ratio (OR) of therapeutic success rates between the two groups comprised the secondary outcome. RESULTS The meta-analysis included 19 studies (four randomized controlled trials and 15 non-randomized studies) with 1,514 participants. The cumulative VRR of EA was 83.908% (95% confidence interval [CI], 79.358% to 88.457%). EA had a significantly higher pooled VRR (SMD, 0.381; 95% CI, 0.028 to 0.734; P=0.030), but not a significantly higher pooled therapeutic success rate (OR, 0.867; 95% CI, 0.132 to 5.689; P=0.880), than other forms of non-surgical management including radiofrequency ablation (RFA), polidocanol sclerotherapy, and simple aspiration with or without saline flush. However, the VRR and therapeutic success rate were not significantly different between EA and RFA. Major complications were recorded only in six patients (0.53%) with self-limiting dysphonia. CONCLUSION The role of EA as the first-line treatment for benign thyroid cysts and predominantly cystic nodules is supported by its high effectiveness and good safety profile compared to other currently available non-surgical options.

Abstract
PURPOSE In this study, we aimed to retrospectively evaluate the volumes and cosmetic scores of mixed-type and spongy-type thyroid nodules treated with ethanol and radiofrequency (RF) ablation before and after treatment. In addition, the safety and efficacy of ethanol and RF ablation treatment methods were compared. METHODS In the radiology department, mixed-type and spongy-type benign thyroid nodules undergoing ethanol and RF ablation between February 2015 and March 2020 were evaluated retrospectively. Consequently, 50 patients who received ethanol ablation therapy and 46 patients who received RF ablation therapy were included in the study. Nodule volumes obtained in pretreatment, third-month, and sixth-month control ultrasounds were noted. Similarly, the cosmetic scores obtained pretreatment and at the sixth-month follow-up were recorded for all patients. RESULTS All of the patients had a single nodule, and 46 patients (47.9%) received RF ablation, and 50 patients (52.1%) received ethanol ablation. The mean volume pretreatment in nodules with RF ablation was 21.41 ml, at the third-month control was 5.68 ml, and at the sixth-month control, it was 4.12 ml (p < 0.05). In ethanol ablation therapy, the mean volume pretreatment was 20.52 ml, at the third-month control was 8.76 ml and at the sixth-month control was 6.01 ml (p < 0.05). CONCLUSION A minimally invasive approach is increasingly used in the treatment of benign thyroid nodules. Our study showed that RF ablation was somewhat more successful in reducing cosmetic scores in patients with biopsy-proven benign mixed-type and spongy-type thyroid nodules, and both techniques were similarly effective in volume reduction.

Cho W, Sim JS, Jung SL. Ultrasound-guided ethanol ablation for cystic thyroid nodules: effectiveness of small amounts of ethanol in a single session. Ultrasonography 2020; 40:417-427. [PMID: 33721967 PMCID: PMC8217798 DOI: 10.14366/usg.20170] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Accepted: 12/22/2020] [Indexed: 12/14/2022] Open
Abstract
Purpose The aim of this study was to evaluate the efficacy of ethanol ablation (EA) in the treatment of cystic thyroid nodules using low-dose ethanol regardless of the initial volume of the nodule or properties of the aspirate. Methods Sixty-one nodules in 60 patients were treated with EA from October 2013 to January 2020. In each patient, EA was performed only once, using less than 5 mL of ethanol (99.5%) instilled and removed completely after a few minutes of retention. Nodule volume, the symptom score, the cosmetic score, and complications were evaluated before and after treatment. The therapeutic success rate (TSR) and volume reduction rate (VRR) according to nodule volume and properties of the aspirate were evaluated. Therapeutic success was defined as the absence of any residual fluid or sufficient volume reduction (≥50%) with improvement of nodule-related symptoms. Results The 61 nodules comprised 38 pure cysts and 23 predominantly cystic nodules. The initial nodule volume was 21.9±15.2 mL (range, 4.4 to 77.2 mL). The TSR was 88.5% (100% in pure cysts and 69.6% in predominantly cystic nodules, P<0.001). The TSR of pure cysts was 100% regardless of nodule volume and properties of the aspirate. In predominantly cystic nodules, the TSR and VRR gradually decreased as volume increased. One patient experienced arrhythmia during the procedure, but completely recovered without sequelae. Conclusion Single-session EA using low-dose ethanol might be effective for the treatment of symptomatic cystic thyroid nodules regardless of the initial cyst volume and properties of the aspirate, especially in pure cysts.

Abstract
AIM To evaluate the long-term efficacy of percutaneous ethanol injection treatment (PEIT) as an alternative to thyroid surgery in symptomatic thyroid cysts. PATIENTS AND METHODS 100 subjects (48±12 years; 58% women) with symptomatic thyroid cysts relapsing after drainage were prospectively included. PEIT was conducted using an established procedure, and the initial cyst volume, symptoms and pain perceived by the patient were assessed. The volume of instilled alcohol was ≤2ml without re-extraction in all cases. Patients were followed-up for more than 3 years and final cyst volume and symptom improvement were assessed. RESULTS Mean maximum cyst diameter before drainage was 3.1±1.2cm. In 71% of patients ≤2 PEIT sessions were required. Median maximum cyst volume was 12.7 (5.4-21.7)ml before the first drainage and median total volume extracted from the cysts was 13.0 (6.2-37.0)ml. After a mean follow-up period of 52±10 months, 98% of patients reported a complete absence of symptoms. The final median volume for the whole group was 0.8 (0.1-2.0)ml with a median volume reduction of 94 (81-99)%. A final volume reduction greater than 65% was observed in 90% of cases. Reported pain during the procedure was absent or mild in 76.4% of cases. CONCLUSIONS PEIT is a safe and well-tolerated first-line treatment for symptomatic thyroid cysts with long-term effectiveness.

Abstract
PURPOSE We evaluated the use of three criteria to determine the need for additional treatment of cystic thyroid nodules after their recurrence following ethanol ablation (EA). METHODS In total, 154 patients (male:female=30:124; mean age, 53.4 years; range, 23 to 79 years) with 154 thyroid nodules (49 cystic and 105 predominantly cystic nodules) who presented between January 2014 and August 2017 were enrolled. All patients underwent follow-up ultrasonography (US) 1 month after EA, and were divided into therapeutic success and failure groups. Therapeutic success was defined as the absence of any residual fluid or sufficient volume reduction (≥50%) with improvement of nodule-related symptoms. The therapeutic failure was defined according to three previously suggested criteria for recommending additional treatment: nodules with ≥1 mL of remnant fluid (criterion 1), volume reduction <50% (criterion 2), and demonstration of a solid component with vascularity (criterion 3). RESULTS Thyroid nodules treated by EA showed significant volume reduction (18.4±21.6 mL to 4.2±6.5 mL [1-month follow-up] to 1.9±3.3 mL [final follow-up], P<0.001) and improvement in clinical problems. Therapeutic failure were 26 patients according to criteria 1, 14 patients according to criteria 2, and 35 patients according to criteria 3. Additional treatment was unnecessary in 81.3%, 70.0%, and 77.8% of patients deemed to need it according to criteria 1, 2, and 3, respectively. CONCLUSION The choice to perform additional treatment after EA should be made according to a combination of clinical problems and US features. Understanding this concept will be useful in planning further treatment following US-guided EA.

Abstract
OBJECTIVES To evaluate the safety and efficacy of percutaneous ethanol ablation (PEA) on indeterminate thyroid nodules (Bethesda III and IV) based on ultrasound (US) elastography by assessing the volume reduction rate (VRR), relative reduction in size, resolution of compressive symptoms, and post-procedural complications. MATERIALS AND METHODS This is a retrospective cohort study of all thyroid nodules treated with PEA by a single surgeon at a North American tertiary referral center. Study variables included demographics, nodule characteristics, Bethesda classification, US elastography, presence of compressive symptoms, thyroid function, and post-procedural complications. Relative volume reductions and VRR were calculated at 3- and 6-month follow-ups. RESULTS Thirty-four thyroid nodules were evaluated in 22 patients. All thyroid nodules underwent a fine needle aspiration prior to PEA. After 6 months, 45% of all thyroid nodules exhibited a VRR of ≥50%. A significant VRR was achieved in the soft thyroid nodules at 6 months (42.15% ± 31), compared to the stiff nodules with 30.92% ± 91.53, P < .05. Post-PEA thyroid stimulating hormone levels did not significantly change after the procedure. Compressive symptoms resolved in all 5 patients who reported it. One patient developed transient vocal cord paresis that resolved in 3 months. DISCUSSION To the best of our knowledge, this is the largest series of PEA for thyroid nodules in North America. Ultrasound elastography is a useful adjunct in predicting the success of PEA for nonmalignant thyroid nodules. Percutaneous ethanol ablation is both a safe and effective alternative to surgery for relief of compressive symptoms in select patients.

Abstract
Due to the increasing rates of physical examination and application of advanced ultrasound machines, incidences of benign thyroid nodules (BTNs) and papillary thyroid microcarcinoma (PTMC) were dramatically up-regulated in recent years. Thermal ablation (TA) has been widely used and regarded as a safe and effective method to eliminate or reduce BTNs and recurrent low-risk PTMC. However, conclusions using TA to treat primary PTMC are controversial. Recently, several long-term and prospective studies on TA treatment of BTNs and primary PTMC have been reported. Here, we review current literatures and progress on TA treatment of BTNs and PTMC and underline the way to get the best treatment outcomes, providing a comprehensive insight into the research progresses in this field.

Abstract
Purpose Thermal ablation is a novel treatment alternative for benign thyroid nodules, and one of the most promising thermal ablation techniques is radiofrequency ablation (RFA). Considering the increasing use of thyroid RFA, some scientific societies have proposed clinical practice guidelines. We systemically reviewed and compared these guidelines for thyroid RFA to identify a standard treatment strategy that represents the positions of most societies. Methods We searched the MEDLINE and EMBASE databases for studies with human participants that were published in English between January 1, 2000 and August 2, 2019. Studies containing clinical practice guidelines for the RFA of benign thyroid nodules were included. We extracted data regarding indications, pre- and post-procedural evaluations, treatment techniques, and the need to obtain informed consent. Results Of the 83 studies found, four studies were included, and one study was added after searching the bibliographies of those articles. The five included studies were guidelines developed by the Korean Society of Thyroid Radiology, a group of experts from Italian scientific societies, the Italian Working Group on Minimally Invasive Treatments of the Thyroid, the United Kingdom’s National Institute for Health and Clinical Excellence, and a group of four professional Austrian thyroid associations. Indications, pre- and post-procedural evaluations, and techniques were similar across studies; however, differences in each of these categories were found. Conclusion While the reviewed guidelines are similar with regard to major categories, international guidelines for the RFA of benign thyroid nodules should be established in the future.
