ABSTRACT There is increasing interest in ultrasound-guided ablation treatments for thyroid diseases, including benign and malignant ones. Surgeons, radiologists, and endocrinologists carry out these treatments, and various organizations within these specialties have recently released multiple international consensus statements and clinical practice standards. The aim of the present consensus statement is to provide guidance, cohesion, and standardization of best practices for thermal ablation procedures of thyroid nodules. The statement includes the indications for these procedures, preprocedural evaluations, technical aspects of the procedures, posttreatment care, follow-up, complications, and training recommendations. This document was written by a panel of specialists from the Brazilian Society of Interventional Radiology and Endovascular Surgery (SOBRICE), the Brazilian Society of Head and Neck Surgery (SBCCP), and the Brazilian Society of Endocrinology and Metabolism (SBEM). The statement does not aim to provide criteria for assessing the capability of specialists to perform the procedure. Instead, it aims to promote the standardization of best practices to reduce potential adverse outcomes. Additionally, it strives to enhance the delivery of high-quality care and the widespread adoption of these technologies on a national level. The recommendations collectively serve as a guidebook for applying best practices in thyroid ablation. ultrasoundguided ultrasound guided diseases ones Surgeons radiologists standards guidance cohesion nodules evaluations followup, followup follow up, up follow-up complications SOBRICE, SOBRICE , (SOBRICE) SBCCP, SBCCP (SBCCP) SBEM.

ABSTRACT Objective: Choosing Wisely (CW) is an initiative that aims to advance the dialogue between physicians and patients about low-value health interventions. Given that thyroid conditions are frequent in clinical practice, we aimed to develop an evidence-based list of thyroid CW recommendations. Materials and methods: The Thyroid Department of the Brazilian Society of Endocrinology and Metabolism (SBEM) named a Task Force to conduct the initiative. The Task Force work was based on an electronic Delphi approach. The 10 recommendations that received the highest scores by the Task Force were submitted for voting by all SBEM associates. The 5 recommendations that received the highest scores by SBEM associates are presented herein. Results: The Task Force was composed of 14 thyroidologists from 10 tertiary-care, teaching-based Brazilian institutions. The brainstorming/ideation phase resulted in 69 recommendations. After the removal of duplicates and recommendations that did not adhere to the initiative's scope, 35 remained. Then the Task Force voted to attribute a grade (0 [lowest agreement] to 10 [highest agreement]) for each recommendation. The 10 recommendations that received the highest scores by the Task Force were submitted to all SBEM associates. A total of 683 associates voted electronically, attributing a grade (0 to 10) for each recommendation. The 5 recommendations that received the highest scores by the SBEM associates compose our final list. Conclusion: A set of recommendations to avoid unnecessary medical tests, treatments, or procedures for thyroid conditions are offered with a transparent methodology. This initiative aims to foster productive interactions between physicians and patients, stimulating shared decision-making.

Objetivo O objetivo deste estudo foi avaliar a eficácia e segurança da injeção percutânea de etanol (IPE) no tratamento de nódulos tireoidianos benignos. Sujeitos e métodos Foram avaliados 120 pacientes com nódulos benignos de tireoide. Todos realizaram dosagens de TSH, T4 livre, ecografia cervical (US) e cintilografia de tireoide (em pacientes com TSH suprimido). A aplicação de etanol estéril a 99% foi guiada por US e o volume de etanol injetado correspondeu a um terço do volume nodular calculado. A resposta foi considerada completa (redução de 90%); parcial (redução entre 50 e 90%) ou ausência de resposta (redução menor que 50%). Nos nódulos autônomos, foi avaliada a normalização do TSH. Resultados Entre os nódulos estudados, 30,8% eram sólidos, 56,7% eram mistos, 12,5% eram císticos e 21,6%, nódulos hiperfuncionantes. O volume inicial dos nódulos tratados variou de 0,9 a 74,8 mL (média 13,1 ± 12,4 mL). Foram realizadas de 1 a 8 sessões de IPE (média 2,8), com aplicação média de 6,2 mL de etanol por paciente. Após dois anos de seguimento, 17% dos pacientes obtiveram resposta completa (redução de 94%), 53% obtiveram resposta parcial (redução de 70%) e 30% não responderam. Houve redução de volume nos nódulos autônomos em 70% dos casos, e 54% normalizaram o valor do TSH. Os efeitos colaterais registrados foram decorrentes apenas do desconforto no local de aplicação. Conclusão Este trabalho mostrou que a IPE é um procedimento seguro e eficaz para tratamento de nódulos benignos, sólidos ou mistos de tireoide. Na maioria dos casos, ocasiona redução do volume nodular, com melhora dos sintomas compressivos e normalização da função tireoidiana. Arq Bras Endocrinol Metab. 2014;58(9):912-7

Objective The objective of this study was to evaluate the efficacy and safety of percutaneous ethanol injection (PEI) in the treatment of benign thyroid nodules. Subjects and methods We evaluated 120 patients with benign thyroid nodules. Patients underwent evaluation of serum TSH and free T4, cervical ultrasound, and thyroid scintigraphy (in those with suppressed TSH levels). The application of sterile ethanol 99% was guided by ultrasound, with the injected volume amounting to one-third of the nodule volume. Response was considered complete (reduction of 90%); partial (reduction between 50 and 90%); or none (reduction of < 50%). Autonomous nodules were evaluated for normalization of TSH levels. Results Among the nodules studied, 30.8% were solid, 56.7% were mixed, 12.5% were cystic, and 21.6% were hyperfunctioning. The initial volume of the treated nodules ranged from 0.9 to 74.8 mL (mean 13.1 ± 12.4 mL). We performed 1-8 sessions of PEI, applying an average of 6.2 mL of ethanol for patient. After 2 years of follow-up, 17% of patients achieved a complete response (94% reduction); 53%, a partial response (70% reduction); and 30%, no response. A reduction in the volume of autonomous nodules was noted in 70% of cases, and 54% had a normalized value of TSH. The main side effect is local pain, lasting less than 24 hours in most cases. Conclusion This study showed that PEI is a safe and effective procedure for treatment of benign, solid or mixed thyroid nodules. Most cases resulted in significant reduction in nodule volume, with normalization of thyroid function. Arq Bras Endocrinol Metab. 2014;58(9):912-7
