Preliminary experience of gasless transoral vestibular robotic thyroidectomy / 中华耳鼻咽喉头颈外科杂志

Objective: To explore the feasibility and safety of the gasless transoral vestibular robotic thyroidectomy using skin suspension. Methods: The clinical data of 20 patients underwent gasless transoral vestibular robotic thyroidectomy in the Department of Otorhinolaryngology, Sun Yat-sen Memorial Hospital, Sun Yat-sen University from February 2022 to May 2022 were retrospectively analyzed. Among them, 18 were females and 2 were males, aged (38.7±8.0) years old. The intraoperative blood loss, operation time, postoperative hospital stay, postoperative drainage volume, postoperative pain visual analogue scale (VAS) score, postoperative swallowing function swallowing impairment score-6 (SIS-6), postoperative aesthetic VAS score, postoperative voice handicap index-10 (VHI-10) voice quality, postoperative pathology and complications were recorded. SPSS 25.0 was used for statistical analysis of the data. Results: The operations were successfully completed without conversion to open surgery in all patients. Pathological examination showed papillary thyroid carcinoma in 18 cases, retrosternal nodular goiter in 1 case, and cystic change in goiter in 1 case. The operative time for thyroid cancer was 161.50 (152.75, 182.50) min [M (P25, P75), the same below] and the average operative time for benign thyroid diseases was 166.50 minutes. The intraoperative blood loss 25.00 (21.25, 30.00) ml. In 18 cases of thyroid cancer, the mean diameter of the tumors was (7.22±2.02) mm, and lymph nodes (6.56±2.14) were dissected in the central region, with a lymph node metastasis rate of 61.11%. The postoperative pain VAS score was 3.00 (2.25, 4.00) points at 24 hours, the mean postoperative drainage volume was (118.35±24.32) ml, the postoperative hospital stay was 3.00 (3.00, 3.75) days, the postoperative SIS-6 score was (4.90±1.58) points at 3 months, and the postoperative VHI-10 score was 7.50 (2.00, 11.00) points at 3 months. Seven patients had mild mandibular numbness, 10 patients had mild cervical numbness, and 3 patients had temporary hypothyroidism three months after surgery and 1 patient had skin flap burn, but recovered one month after surgery. All patients were satisfied with the postoperative aesthetic effects, and the postoperative aesthetic VAS score was 10.00 (10.00, 10.00). Conclusion: Gasless transoral vestibular robotic thyroidectomy using skin suspension is a safe and feasible option with good postoperative aesthetic effect, which can provide a new treatment option for some selected patients with thyroid tumors.

Analysis of risk factors for recurrence of differentiated thyroid carcinoma after surgical resection combined with iodine-131 and TSH suppression therapy / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate the risk factors of recurrence after surgical resection of differentiated thyroid carcinoma combined with iodine-131 and TSH（Thyroid stimulating hormone） inhibition therapy. Methods:From January 2015 to April 2020, the clinical data of patients with structural recurrence and without recurrence were retrospectively collected after surgical treatment combined with iodine-131 and TSH inhibition therapy in the First Medical Center of PLA General Hospital. The general conditions of the two groups of patients were analyzed and the measurement data in line with the normal distribution was used for comparison between groups. For measurement data with non-normal distribution, the rank sum test was used for inter-group comparison. The Chi-square test was used for comparison between the counting data groups. Univariate and multivariate regression analyses were used to determine the risk factors associated with relapse. Results:The median follow-up period was 43 months（range 18-81 months） and 100 patients（10.5%） relapsed among the 955 patients. Univariate analysis showed that tumor size, tumor multiple, the number of lymph node metastases>5 in the central region of the neck, and the number of lymph node metastases>5 in the lateral region were significantly correlated with post-treatment recurrence（P<0.001, P=0.018, P<0.001, P<0.001）. Multivariate analysis showed that tumor size（adjusted odds ratio OR: 1.496, 95%CI: 1.226-1.826, P<0.001）, tumor frequency（adjusted odds ratio OR: 1.927, 95%CI: 1.003-3.701, P=0.049）, the number of lymph node metastases in the central neck region>5（adjusted odds ratio OR: 2.630, 95%CI: 1.509-4.584, P=0.001） and the number of lymph node metastases in the lateral neck region>5（adjusted odds ratio OR: 3.074, 95%CI: 1.649-5.730, P=0.001） was associated with tumor recurrence. Conclusion:The study showed that tumor size, tumor multiple, the number of lymph node metastases in the central region of the neck>5 and the number of lymph node metastases in the side of the neck >5 are independent risk factors for recurrence of differentiated thyroid cancer after surgical resection combined with iodine-131 and TSH inhibition therapy.

Para os sintomas totais (p=0,001) e vocais (p=0,001) relacionados à tireoidectomia, os valores do M3 foram significativamente menores que os do M2. Na autoavaliação de sintomas vocais dos domínios total e limitação, o M1 (p<0,001; p<0,001) e o M3 (p=0,013; p=0,001) apresentaram valores significativamente menores que o M2. Indivíduos do gênero masculino apresentaram percepção de sintomas de fadiga no domínio fadiga e limitação vocal (p=0,035) e percepção de sintomas relacionados à tireoidectomia nos domínios total (p=0,044) e sintomas vocais (p=0,012) significativamente menores do que os do gênero feminino, independentemente do momento. Conclusão Sintomas vocais físicos e relacionados à tireoidectomia diminuem no pós-operatório tardio; sintomas vocais totais e limitação aumentam no pós-operatório imediato e diminuem no tardio. Mulheres têm maior percepção de fadiga e limitação vocal e de sintomas totais e vocais relacionados à tireoidectomia.

ABSTRACT Purpose To verify the self-perception of symptoms and vocal fatigue related to thyroidectomy in individuals with thyroid cancer in the pre, immediate post and late post-operative moments, and to analyze the influence of gender. Methods Intervention study before and after with 20 individuals, mean age 46 years, evaluated before surgery (M1), immediately after surgery (M2) and in the late postoperative period (M3) of thyroidectomy. Individuals answered the instruments: Voice Symptoms Scale, Vocal Fatigue Index and Thyroidectomy-Related Voice and Symptom Questionnaire. Data were analyzed descriptively and inferentially. Results In self-assessment of vocal symptoms of the total domains and limitation, M1 (p<0.001; p<0.001, respectively) and M3 (p=0.013; p=0.001, respectively) had significantly lower values than the M2. For the physical domain of self-assessment of vocal symptoms, the M3 showed statistically lower values than the M1 (p=0.006) and the M2 (p<0.001) assessments. Depending on the moment, the oropharyngolaryngeal symptoms in M3 had significantly lower values ​​than M2 (p=0.004) and M1 (p=0.028). Male scores were significantly lower than female scores in the self-assessment of fatigue symptoms in the fatigue and vocal limitation domain (p=0.035), regardless of the time of assessment. Conclusion Physical vocal symptoms and thyroidectomy-related symptoms decrease in the late postoperative period; total vocal symptoms and limitation increasing in the immediate postoperative period and decrease in the late postoperative period. Women have a higher perception of vocal fatigue and limitation, and of total and vocal symptoms related to thyroidectomy.

El 61,5% presentó hipocalcemia en las primeras 72 horas del postoperatorio: 60,2% de mujeres y 71,4% de hombres (p=0.42). El 79% fueron hipocalcemias asintomáticas, 7,5% tuvo síntomas y 13,5% sin datos. El signo de Trousseau fue negativo 68% y positivo en 9%. Respecto a la patología hubo 107 resultados benignos, 94 malignos. CONCLUSIONES: el 90% fueron mujeres, 6 de cada 10 presentaron hipocalcemia en las primeras 72hs, en la gran mayoría fueron asintomáticas y tuvieron signo de Trousseau negativo. No hubo correlación entre hipocalcemia con edad, sexo, duración o tiempo de la cirugía, ni resultado de patología. La incidencia de hipoparatiroidismo transitorio fue 75,7% y permanente 7,3%. Cuando no hubo hipoparatiroidismo transitorio tampoco hubo hipoparatiroidismo permanente.

INTRODUCTION: hypoparathyroidism is the alteration caused by hypofunction of the parathyroid glands and the most common cause is post-surgery. OBJECTIVE: to know the incidence of hypocalcaemia within 72 hours of the postoperative period and of permanent hypoparathyroidism of thyroidectomies in nine years. SUBJECTS AND METHOD: observational, descriptive and retrospective study of patients with thyroidectomies between January 2011 and December 2019 at Clinical's Hospital. The sample was divided by age groups, hypocalcemia was considered at values ≤8.5 mg/dl and permanent hypoparathyroidism when they persisted for at least one year after surgery. RESULTS: there were 202 patients, 182 women and 20 men, mean age ± SE for women 47.3±1.2 years and for men 55.1±3.4. 61.5% presented hypocalcaemia in the first 72 hours after surgery: 60.2% of women and 71.4% of men (p=0.42). 79% were asymptomatic hypocalcemia, 7.5% had symptoms and 13.5% without data. Trousseau's sign was negative in 68% and positive in 9%. Regarding the pathology, there were 107 benign results, 94 malignant. CONCLUSIONS: 90% were women, 6 out of 10 presented hypocalcemia in the first 72 hours, the vast majority were asymptomatic and had a negative Trousseau sign. There was no correlation between hypocalcaemia with age, sex, duration or time of surgery, or pathology result. The incidence of transient hypoparathyroidism was 75.7% and permanent 7.3%. When there was no transient hypoparathyroidism, there was also no permanent hypoparathyroidism.

Trans Oral Endoscopic Thyroidectomy Vestibular Approach (TOETVA) in Brazil: Safety and complications during learning curve

ABSTRACT Background: 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.

Impacto do tipo de bisturi no tempo operatório e complicações agudas em tireoidectomias / Impact of scalpel type on operative time and acute complications in thyroidectomies

Resumo Introdução: A cirurgia mais comum da região cervical é a tireoidectomia. Atualmente, várias tecnologias estão disponíveis para hemostasia intraoperatória. Objetivo: Comparar o desempenho de três tecnologias (elétrica monopolar e bipolar e ultrassônica) no tempo operatório e complicações pós-operatórias. Método: Pacientes submetidos à tireoidectomia total sem tratamento prévio foram incluídos. Desenho científico usado: estudo de série prospectiva. Resultados: Foram incluídos 834 pacientes, 661 mulheres (79,3%) e 173 homens (20,7%). O diagnóstico foi de neoplasia maligna em 528 pacientes (63,3%) e de doença benigna em 306 pacientes (36,7%). O bisturi elétrico monopolar foi usado em 280 pacientes (33,6%), energia bipolar em 210 (25,2%) e ultrassônica em 344 (41,3%). O tempo operatório foi significantemente menor com bisturi ultrassônico ou bipolar quando comparado com elétrico. Em um modelo de regressão linear, sexo, diagnóstico de malignidade e tipo de energia foram significantes para duração do procedimento. Os pacientes operados com bisturi ultrassônico ou bipolar apresentaram incidência significantemente menor de hipoparatireoidismo. Conclusão: O uso do bisturi ultrassônico ou bipolar reduz de forma significante o tempo operatório e a incidência de hipoparatireoidismo transitório.

Preoperative vitamin D level as a post-total thyroidectomy hypocalcemia predictor: a prospective study / Nível pré-operatório de vitamina D como preditor de hipocalcemia pós-tireoidectomia total: estudo prospectivo

Abstract Introduction: Hypocalcemia is one of the most common complications after total thyroidectomy. Preoperative serum vitamin D concentration has been postulated as a risk factor for this complication. However, the subject is still controversial and the role of vitamin D in the occurrence of hypocalcemia remains uncertain. Objective: To evaluate the capability of preoperative vitamin D concentrations in predicting post-total thyroidectomy hypocalcemia. Methods: Forty-seven total thyroidectomy patients were prospectively evaluated for serum 25(OH) vitamin D, calcium and parathyroid hormone before surgery, Calcium every 6 hours, and parathyroid hormone 8 hours post-operatively. Patients were divided according to postoperative corrected calcium into groups without (corrected calcium ≥8.5 mg/dL) and with hypocalcemia (corrected calcium <8.5 mg/dL), who were then evaluated for preoperative 25(OH) vitamin D values. Results: A total of 72.3% of cases presented altered 25(OH) vitamin D preoperative serum concentrations and 51% evolved with postoperative hypocalcemia. The with and without hypocalcemia groups did not differ for preoperative 25(OH) vitamin D (p = 0.62). Univariate analysis showed that age (p = 0.03), postoperative PTH concentration (p = 0.02), and anatomopathological diagnosis of malignancy (p = 0.002) were predictors of postoperative hypocalcemia. In multivariate analysis only parathyroid hormone in postoperative (p = 0.02) was associated with post-total thyroidectomy hypocalcemia. Conclusion: Preoperative serum concentrations of 25(OH) vitamin D were not predictors for post-total thyroidectomy hypocalcemia, whereas postoperative parathyroid hormone influenced the occurrence of this complication.

Resumo Introdução: A hipocalcemia é uma das complicações mais comuns após a tireoidectomia total. A concentração sérica de vitamina D tem sido apontada como fator de risco para essa complicação. No entanto, o assunto ainda é controverso e o papel da vitamina D na ocorrência de hipocalcemia permanece incerto. Objetivo: Avaliar se os níveis pré-operatórios de vitamina D são capazes de predizer a hipocalcemia pós-tireoidectomia total. Método: Quarenta e sete pacientes com tireoidectomia total foram avaliados prospectivamente quanto aos níveis séricos de 25(OH)vitamina D, cálcio e paratormônio antes da cirurgia, cálcio a cada 6 horas e paratormônio 8 horas após a cirurgia. Os pacientes foram divididos de acordo com o cálcio corrigido no pós-operatório em grupos sem (cálcio corrigido ≥ 8,5 mg/dL) e com hipocalcemia (cálcio corrigido < 8,5 mg/dL), que foram avaliados em relação aos valores pré-operatórios de 25(OH)vitamina D. Resultados: 72,3% dos casos apresentaram concentrações séricas pré-operatórias alteradas de vitamina D- 25 hidroxi e 51% desenvolveram hipocalcemia no pós-operatório. Os grupos com e sem hipocalcemia não diferiram para a 25(OH)vitamina D pré-operatório (p = 0,62). A análise univariada mostrou que a idade (p = 0,03), a concentração de paratormônio no pós-operatório (p = 0,02) e o diagnóstico anatomopatológico de malignidade (p = 0,002) foram preditores de hipocalcemia no pós-operatório. Na análise multivariada, apenas o paratormônio no pós-operatório (p = 0,02) foi associado a hipocalcemia pós-tireoidectomia total. Conclusão: As concentrações séricas pré-operatórias de 25(OH)vitamina D não foram preditores de hipocalcemia pós-tireoidectomia total, enquanto o paratormônio pós-operatório influenciou a ocorrência dessa complicação.

PTH como predictor de hipocalcemia postiroidectomía total / PTH as a predictor of hypocalcemia after total thyroidectomy

Resumen Objetivo: Evaluar la asociación entre el valor de PTH medido a las 6 h posoperatorias de los pacientes sometidos a una tiroidectomía total, y la presentación de hipocalcemia en las primeras 24 h posoperatorias. Materiales y Método: Estudio analítico retrospectivo que utiliza una base de datos de 173 pacientes operados de tiroidectomía total entre enero de 2016 a diciembre de 2018 en el Hospital Militar de Santiago (HMS). Se revisaron datos demográficos y perioperatorios. Se utilizó curva ROC para evaluar la asociación entre PTH e hipocalcemia en nuestros pacientes. Resultados: 106 pacientes que cumplen criterios de inclusión. Promedio de PTH 30,5 (1,4-169), 58% presentó hipocalcemia, solo 17 pacientes fueron sintomáticos. PTH promedio en pacientes sintomáticos fue de 7,8 pg/ml. Curva ROC con área bajo la curva de 0,83 (0,75-0,92). Considerando valores útiles para la práctica clínica, una PTH menor a 6,3 (valor más bajo en nuestro laboratorio), tiene sensibilidad de 97%. El valor 18 de PTH (límite inferior del rango de normalidad del laboratorio) se obtiene 88,89% de sensibilidad con 66,07% de especificidad. Y con un valor de 47 pg/ml, se obtiene con un 91% de especificidad para predecir pacientes que no tendrían hipocalcemia. Conclusión: Con un valor de PTH disminuido bajo su valor normal, se puede decir que el riesgo de tener hipocalcemia es sobre el 80%, por lo que se debería iniciar tratamiento profiláctico y desistir del alta. En cambio, para definir un valor superior sobre el cual dar de alta precoz con seguridad, faltan más estudios.

Aim: To evaluate the association between PTH (parathormone) value measured at 6 hours postoperatively of patients submitted to total thyroidectomy, and the presentation of hypocalcemia in the first 24 hours. Materials and Method: Retrospective study of 173 patients with total thyroidectomy between January 2016 to December 2018 in HMS. Demographic and perioperative data were reviewed. The ROC curve was used to evaluate the association between PTH and hypocalcemia in our patients. Results: 106 patients meet inclusion criteria. Average of PTH 30.5 (1.4-169), 58% presented hypocalcemia, 17 patients were symptomatic. ROC curve with area under the curve of 0.83 (0.75-0.92) was obtained considering useful values for clinical practice, a PTH less than 6.3 (lowest value in our laboratory), has 97% sensitivity to predict hypocalcemia. If we use the value 18 we obtain 88.89% sensitivity with 66.07% specificity. And with a value of 47, it is obtained with 91% specificity to predict patients who would not have hypocalcemia Conclusion: With a PTH value decreased below its normal value, it can be said that the risk of having hypocalcemia is over 80%, so that prophylactic treatment should be initiated. To define a value on which to register early with security, more study is needed.

Voice- and swallowing-related symptoms after total thyroidectomy: evidence from a Brazilian national survey / Sintomas relacionados à voz e deglutição após tireoidectomia total: evidências de uma pesquisa nacional brasileira

ABSTRACT Purpose: to estimate the prevalence of voice- and swallowing-related symptoms in women submitted to total thyroidectomy. Methods: a population-based, observational, cross-sectional, analytical study, based on a Brazilian national survey. A total of 252 women, aged 18 to 58 years, submitted to total thyroidectomy, residing in the five geographical regions of the country participated in the study. All of them answered the version of the Thyroidectomy-Related Voice Questionnaire translated and adapted into Brazilian Portuguese, besides questions on demographic and clinical issues. A descriptive analysis of the categorical and quantitative variables was conducted. The relationship between the total TVQ score and the independent variables was analyzed with the Mann-Whitney and Kruskal-Wallis tests. The significance level used was 5%. Results: the most prevalent symptoms were, tired voice, after talking for a long time (50%), and dry mouth/thirst (43.3%). The voice-related symptoms were more prevalent than those related to swallowing. The total TVQ score was not related to age group (p=0.141), profession (p=0.213), region of residence (p=0.303), time since surgery (p=0.955), and radiotherapy/radioiodine therapy (p=0.666). Conclusion: Brazilian women submitted to total thyroidectomy have a high prevalence of voice- and swallowing-related symptoms, the former being predominant.

RESUMO Objetivo: estimar a prevalência de sintomas relacionados à voz e deglutição em mulheres submetidas à tireoidectomia total. Métodos: estudo de base populacional, observacional, transversal e analítico, baseado em um survey nacional brasileiro. Participaram do estudo 252 mulheres submetidas à tireoidectomia total, com idades entre 18 e 58 anos, residentes nas cinco regiões geográficas do país. Todas responderam a versão traduzida e adaptada para o português brasileiro do Thyroidectomy-Related Voice Questionnaire (TVQ), além de questões demográficas e clínicas. Foi realizada análise descritiva das variáveis categóricas e quantitativas. A relação entre escore total do TVQ e variáveis independentes foi analisada por meio dos testes de Mann-Whitney e Kruskal-Wallis. O nível de significância foi de 5%. Resultados: os sintomas mais prevalentes foram sensação de voz cansada depois de conversar por muito tempo (50%) e percepção de boca seca/sede (43,3%). Sintomas vocais foram mais prevalentes que os relacionados à deglutição. O escore total do TVQ não se relacionou com faixa etária (p=0,141), profissão (p=0,213), região de residência (p=0,303), tempo de cirurgia (p=0,955) e radioterapia/radioiodoterapia (p=0,666). Conclusão: mulheres brasileiras submetidas à tireoidectomia total possuem alta prevalência de sintomas relacionados à voz e deglutição, com predomínio dos sintomas vocais seguidos dos sintomas relacionados à deglutição.
