Objective: The aim of this study was to address the first cases of TOETVA done in Brazil, by TOETVA-Bra study group, regarding safety and complications. Materials and methods: Series of the first 93 TOETVAs cases in Brazil. All authors except LPK, AJG JOR and RPT received TOETVA training including cadaveric hands-on in Thailand or United States (Johns Hopkins Medicine) during 2017. After they came back to Brazil and started doing their first TOETVA cases in the cities of Rio de Janeiro, Sao Paulo and Chapecó they agreed to collaborate and gather data using an online spreadsheet. All patients were submitted to the technique described by Anuwong. Results: A total of 93 patients underwent TOETVA. Most patients (58.1%) were submitted to total thyroidectomy and 59.1% had benign disease. Two patients (2.2%) needed conversion to open surgery. Five patients (9.3%) developed transient hypoparathyroidism and there were 3 (2.0%) temporary recurrent laryngeal nerve palsy. There was one (0.7%) permanent unilateral palsy. Twenty patients had some sort of complication, 16.1% were minor and 5.4% were major. A total of 73 patients (78.5%) had an uneventful recovery. Conclusion: The technique is reproducible with a low complication rate. While further studies are needed to confirm equivalency, early efforts suggest that TOETVA is not inferior to traditional open thyroidectomy in appropriately selected patients.

Introduction: percutaneous dilatational tracheostomy is currently one of the main procedures performed in an intensive care unit (ICU). However, there are no well-defined indicators of technical difficulty in performing the procedure. Objectives: to define predictors of difficulty in performing bedside percutaneous dilatational tracheostomy. Methodology: prospective cohort study encompassing 21 patients who underwent bedside percutaneous dilatational tracheostomy in the ICU at a single center. Results: Sternohyoid (SH) distance shorter than 7 cm is associated with a 50% increase in the risk of technical difficulty (OR 0.44 and p <0.03). Conclusion: the reduction in (SH) distance is related to an increased risk of difficulty in performing percutaneous dilatational tracheostomy in the ICU bed.

Introduction: thyroid surgery through the transoral vestibular approach is a reality in many countries. While several competing remote access techniques have been developed in the last 20 years, many were not reproducible. Transoral Endoscopic Neck Surgery (TNS) has been shown to be reproducible in different centers around the world, and approximately five years after its description it has been adopted relatively quickly for various reasons. To date, there are at least 7 Brazilian studies published, including a series of more than 400 cases. The aim of this work is to study the progression of Transoral Neck Surgery in Brazil and describe the profile of surgeons involved in this new approach. Methods: this is a retrospective study with descriptive statistics. A REDCap based survey about transoral endoscopic thyroidectomy and parathyroidectomy vestibular approach (TOETVA/TOEPVA) was done with 66 Brazilian surgeons regarding surgeon profile, numbers of cases performed by geographic region, what kind of training was necessary prior to the first case and behavior of the surgeon proposing these new approaches. Results: response rate of this survey was 53%. To date, 1275 TOETVA/TOEPVA cases had been performed in Brazil, 1229 thyroidectomies (96.4%), 42 parathyroidectomies (3.3%) and 4 combined procedures (0.3%). Most of the cases were done in the southeast region (821, 64.4%), 538 (42.2%) cases in the State of São Paulo and 283 (22.2%) cases in the State of Rio de Janeiro. Conclusions: TOETVA is becoming popular in Brazil. Younger surgeons, especially those between 30 and 50 years old were more likely to adopt this approach.

RESUMO Introdução: a cirurgia de tireoide por via transoral vestibular é uma realidade em muitos países. Embora várias outras técnicas de acesso remoto tenham sido desenvolvidas nos últimos 20 anos, muitas não eram reprodutíveis. A cirurgia endoscópica cervical transoral (TNS - Transoral Neck Surgery) tem se mostrado reprodutível em diferentes centros ao redor do mundo sendo que, aproximadamente cinco anos após sua descrição, foi adotada de forma relativamente rápida por vários motivos. Até o momento, existem pelo menos 7 estudos brasileiros publicados, incluindo uma série de mais de 400 casos. O objetivo deste trabalho é estudar a evolução da Cirurgia Transoral do Pescoço (TNS) no Brasil e descrever o perfil dos cirurgiões envolvidos nesta nova abordagem. Métodos: trata-se de um estudo descritivo. Uma pesquisa online hospedada no REDCap sobre tireoidectomia e paratireoidectomia endoscópica transoral por abordagem vestibular (TOETVA/TOEPVA) foi realizada com 66 cirurgiões brasileiros. Foram levantados dados sobre o perfil do cirurgião, número de casos realizados por região geográfica, que tipo de treinamento foi necessário antes do primeiro caso e comportamento do cirurgião durante o relacionamento com o paciente ao abordar essas novas técnicas. Resultados: a taxa de resposta desta pesquisa foi de 53%. Até o momento, 1.275 casos de TOETVA/TOEPVA foram realizados no Brasil, sendo 1.229 tireoidectomias (96,4%), 42 paratireoidectomias (3,3%) e 4 procedimentos combinados (0,3%). A maioria dos casos foi realizada na região sudeste (821, 64,4%), 538 (42,2%) casos no estado de São Paulo e 283 (22,2%) casos no estado do Rio de Janeiro. Conclusões: a TOETVA está se popularizando no Brasil. Cirurgiões mais jovens, especialmente aqueles entre 30 e 50 anos, são mais propensos a adotar essa abordagem.
