Tiroidectomía total en enfermedad de graves basedow y tiroiditis. Complicaciones postoperatorias y relación con neoplasia tiroidea / Total thyroidectomy in graves basedow disease and thyroiditis. Postoperative complications and relationship with thyroid neoplasia

n. Los centros de alto volumen tienden a realizar tiroidectomías totales, tanto en patologías malignas y benignas. En este trabajo se analizan las complicaciones y la relación de las enfermedades estudiadas con la patología oncológica. Materiales y métodos. Se realizó una revisión de los pacientes intervenidos quirúrgicamente de Tiroidectomía Total (TT) por enfermedad de graves y tiroiditis. Se excluyeron las resecciones tiroideas parciales, subtotales, aquellas que requirieron linfadenectomía cervical y las realizadas por otras afecciones de la glándula entre enero 2010 y enero 2020 en el Servicio de Cirugía General N° 1, Hospital Nacional de Clínicas. Resultados. La histología fue del 64% para enfermedad de Graves, 28% Tiroiditis de Hashimoto y 8% Tiroiditis Linfocitaria (TL). El 100% de las TL presentaron Carcinoma Papilar de Tiroides (CPT) como resultado final de la anatomía patológica. El 25% del examen diferido de la pieza quirúrgica informó (CPT) en EG. Discusión. La complicación posoperatoria que rigió nuestra serie fue el Hipoparatiroidismo, manifestación que se presentó de manera transitoria en el 50% de la población estudiada, perdurando por más de seis meses en solo un caso (6%). Autores como Delbridge y cols. realizan el trasplante sistemático de al menos una paratiroides. La asociación de la neoplasia tiroidea fue elevada en nuestra serie, con una incidencia del 37%. Por lo que la Tiroidectomía debe ser total. Conclusión. La mayoría de los centros de cirugía endocrina del mundo, han difundido ampliamente el uso de la TT, por ser un procedimiento seguro en manos de cirujanos experimentados

n. High volume centers tend to perform total thyroidectomies, both in malignant and benign pathologies. This work analyzes complications and the relationship of diseases studied with oncological pathology. Materials and methods. A review of the patients surgically intervened with total thyroidectomy (TT) due to serious disease and thyroiditis was performed. Partial thyroid resections were excluded, subtotals, those that required cervical lymphadenectomy and those performed by other conditions of the gland between January 2010 and January 2020 in the General Surgery Service No. 1, National Hospital of Clinics. Results. Histology was 64% for serious disease, 28% hashimoto and 8% lymphocyte thyroiditis (TL). 100% of the FTAs presented papillary thyroid carcinoma (CPT) as a final result of the pathological anatomy. 25% of the deferred examination of the surgical piece reported (CPT) in EG. Discussion. The postoperative complication that governed our series was hypoparathyroidism, a demonstration that was presented temporarily in 50% of the population studied, enduring for more than six months in just one case (6%). Authors such as Delbridge et al. They perform the systematic transplant of at least one parathyroid. The Association of Thyroid Neoplasia was high in our series, with an incidence of 37%. So, the thyroidectomy must be total. Conclusion. Most of the world's endocrine surgery centers have widely disseminated the use of TT, for being a safe procedure in the hands of experienced surgeons

An executive summary of the Philippine Interim Clinical Practice Guidelines for the Diagnosis and Management of Well Differentiated Thyroid Cancer 2021

Objectives@#Thyroid cancer is the most common endocrine cancer in the Philippines affecting primarily women in the reproductive age group. Considering the burden of thyroid cancer in the country, the Department of Health (DOH) called for the development of a national clinical practice guideline that would address patient needs, and aid physicians in clinical decision-making while considering therapeutic cost and availability in the local setting. The 2021 guidelines are aimed at providing optimal care to Filipino patients by assisting clinicians in the evaluation of thyroid nodules and management of well differentiated thyroid cancer.@*Methods@#A steering committee convened to formulate clinical questions pertaining to the screening and evaluation of thyroid nodules, surgical and post operative management of thyroid cancer, and palliative care for unresectable disease. A technical working group reviewed existing clinical guidelines, retrieved through a systematic literature search, synthesized clinical evidence, and drafted recommendations based on the ADAPTE process of clinical practice guideline development. The consensus panel reviewed evidence summaries and voted on recommendations for the final statements of the clinical practice guidelines.@*Results@#The guidelines consist of clinical questions and recommendations grouped into six key areas of management of well differentiated thyroid cancer: screening, diagnosis, surgical treatment, post operative management, surveillance, and palliative care.@*Conclusion@#The 2021 guidelines for well differentiated cancer could direct physicians in clinical decision making, and create better outcomes for Filipino patients afflicted with the disease. However, patient management should still be governed by sound clinical judgement and open physician-patient communication.

Incidence of surgical site infections after transcervical thyroidectomy in patients given antibiotics versus those without antibiotics in a government hospital in the Philippines

Background and Objectives@#Surgical site infection (SSI) makes up the largest single group of postoperative infective complications. For surgeries classified as clean surgeries of the head and neck, such as a thyroidectomy, the routine administration of antimicrobial prophylaxis is not recommended. Despite this, extended usage of antibiotics is common in developing countries. This study evaluated the need for antibiotics in elective transcervical thyroidectomy for the prevention of SSI in a tertiary government hospital in a developing country. @*Methods@#This is a retrospective cohort study that included patients who have undergone elective transcervical thyroidectomy at the Department of Otolaryngology - Head and Neck Surgery (ORL-HNS) of the University of the Philippines - Philippine General (UP-PGH) Hospital from August 1, 2020 to June 30, 2022. Data collection was conducted through review of both in-patient and out-patient records.@*Results@#The data of 58 patients were analyzed. The mean (±SD) age was 42.5±14.5 years, with approximately 2:27 male to female ratio. Of the 58 patients, 26 were given postoperative antibiotics while 32 did not receive postoperative antibiotics. None of the 58 were noted to have SSI on the 3rd postoperative day. Only 54 patients completed the 7-day follow-up of the study and their data were further analyzed. One patient had SSI. There was no significant difference between the presence and absence of postoperative antibiotics in relation to SSI (p-value>0.05).@*Conclusion@#This study shows that in patients undergoing transcervical thyroidectomies, there is no significant difference in the occurrence of SSI among patients who received and did not receive postoperative antibiotics. Therefore, there is no need to administer postoperative antibiotics, as long as a sterile surgical technique is ensured.

Clinical manifestations of I-131 induced salivary gland dysfunction in patients with thyroid carcinoma

Aim: To carry out a retrospective analysis of the frequency and severity of clinical signs of radioiodine (131I)-induced damage to the salivary glands in the early and long-term post-radiation periods, and identify risk factors for their occurrence in patients with differentiated thyroid carcinomas. Methods: A total of 330 patients underwent thyroidectomy with dissection of lymphatic nodes. One month after surgery, all the patients received radioiodine therapy. The dose and number of courses varied depending on the stage and morphological type of the tumor. In the late post-radiation period, the patients were surveyed with the use of a standard questionnaire, which allowed retrospective assessment of the nature and severity of symptoms of radiationinduced damage, as well as the time of their onset/subsidence. Results: Radiation-induced sialoadenitis of the salivary glands was observed in 51.2% of patients treated with 131I. The main symptoms included pain and discomfort in the salivary glands (51.2% of patients), swelling (48.8%), transient or permanent dry mouth (38%), and distortion of taste (38%). There were statistically significant correlations between the presence and severity of the main clinical symptoms of salivary gland irradiation. A significant relationship (r = 0.91, p < 0.001) was found between swelling of the salivary glands and the feeling of pain or discomfort, which was indicative of inflammation and retention of saliva. Conclusion: The main factors influencing the formation of chronic radiation-induced sialoadenitis and the severity of the inflammatory process included the tumor stage, the total dose of radiopharmaceuticals, and the duration following radioiodine therapy

Factores de riesgo, predictores y tratamiento de hipocalcemia en pacientes sometidos a tiroidectomía / Risk factors, predictors and treatment of hypocalcemia in patients undergoing thyroidectomy

La tiroidectomía total es la intervención más frecuentemente realizada en cirugía endocrina. En manos de cirujanos experimentados el riesgo de hipocalcemia post- tiroidectomía disminuye; sin embargo, sigue siendo la principal complicación, alcanzando incidencia hasta 60%. Diversos factores son capaces de predecir el riesgo de hipocalcemia: bioquímicos, quirúrgicos, fisiopatológicos. Se realizó búsqueda en internet de artículos originales, revisiones sistemáticas y artículos de revisión en español e inglés, utilizando plataformas y motores de búsqueda (PubMed, Scielo, Biblioteca Virtual en Salud de Honduras, Google académico), período 2014-2023, utilizando los términos tiroidectomía, hipocalcemia, hipoparatiroidismo, para recopilar datos de diagnóstico, tratamiento y prevención de la hipocalcemia post-tiroidectomía. Se concluyó que la hipocalcemia es la complicación más común posterior a una tiroidectomía. Los predictores de hipocalcemia fueron el calcio sérico, hormona paratiroidea (PTH), vitamina D y magnesio preoperatorio. Los pacientes que desarrollen hipocalcemia deben manejarse según el calcio sérico evaluado la mañana siguiente a la cirugía...(AU)

Incidencia de Hipocalcemia Post Tiroidectomía. Factores predictores (PTH, Fósforo, Magnesio) y protocolo de manejo con alta precoz / Post-Thyroidectomy Hypocalcemia: Incidence, Prediction, and Outpatient Management Strategies Based on PTH and Calcium Levels

Se ha propuesto la medición de PTH como predictor de hipocalcemia postoperatoria transitoria y permanente. No hay un estándar de punto de corte o tiempo de toma de muestra. El OBJETIVO es reportar la incidencia de hipocalcemia post tiroidectomía en un grupo quirúrgico de alto volumen y proponer un protocolo de manejo ambulatorio (esquemas de I a V) según niveles postoperatorios (PO) de calcemia, PTHi (normal, baja o indetectable) y síntomas. Y determinar valores de PTH postoperatoria como predictores de hipocalcemia. En 106 pacientes con tiroidectomía total entre 2019 y 2021 se realiza medición de niveles pre y postoperatorios de calcio, magnesio, fosforo y PTHi. Se observó 29% y 1% de hipocalcemia transitoria ( 12 meses). Los puntos de corte para predecir hipocalcemia fueron PTH < 8,8 pg/ml y < 80% de descenso de % de PTH (d % PTH) al día siguiente. Con el manejo propuesto se indica el alta precoz (promedio 1.05 días) y el costo de la prescripción es acotado. No hay asociación significativa de hipomagnesemia e hiperfosfemia PO con la hipocalcemia PO. El tratamiento más utilizado es de carbonato de calcio exclusivo (esquemas I y II). Los pacientes se mantienen con síntomas leves a las 2 semanas PO en 5% y logran suspender el tratamiento vía oral en 93% en este mismo período. Los protocolos de medición de PTH como predictor de hipocalcemia son muy variados. Cada centro debe conocer y establecer sus propios protocolos de manejo. Con esta experiencia demostramos la utilidad y seguridad de un esquema de manejo basado en calcemia, PTH (normal, baja o indetectable) y síntomas, con indicación de tratamiento profiláctico para todos los pacientes y ajuste ambulatorio seguro y de menor costo que una hospitalización prolongada.

INTRODUCTION: PTH measurement has been proposed to predict transient and permanent postoperative hypocalcemia. There is no standard cut-off point or time for sampling. Aim: To report the incidence of post-thyroidectomy hypocalcemia in a high-volume surgical group and propose an outpatient management protocol according to postoperative (PO) calcium levels, iPTH (normal, low, or undetectable), and symptoms. Furthermore, determine postoperative PTH values as predictors of hypocalcemia. Methods: In 106 patients with total thyroidectomy between 2019 and 2021, pre-and postoperative levels of calcium, magnesium, phosphorus, and iPTH were measured. Results: Transient ( 12 months) hypocalcemia was observed in 29% and 1%. Cut-off points to predict hypocalcemia were PTH < 8.8 pg/mL and < 80% decrease in % PTH (d% PTH) the day after surgery. With the proposed management, early discharge is indicated (an average of 1.05 days), and the prescription cost is limited. There is no significant association between PO hypomagnesemia and hyperphosphatemia with PO hypocalcemia. The most widely used treatment is exclusive calcium carbonate (schemes I and II). Patients remain with mild symptoms at two weeks PO in 5% and discontinue oral treatment in 93% in this period. Conclusions: Protocols for measuring PTH as a hypocalcemia predictor vary. Each center must know and establish its management protocols. With this experience, we demonstrate the usefulness and safety of a management scheme based on calcium, PTH (normal, low, or undetectable), and symptoms with an indication of prophylactic treatment for all patients and a safe outpatient setting at a lower cost than prolonged hospitalization.

Beyond the Recommendations of the Clinical Guidelines for Medullary Thyroid Cancer - A Case Report / Más allá de las recomendaciones de las guías clínicas de cáncer medular de tiroides - a propósito de un caso

Medullary thyroid cancer (MTC) is a rare disease from parafollicular C cells. Calcitonin has been suggested as a screening; its levels are proportional to the tumor size and predictive of metastatic disease. We present a case where an early action was taken with lower cut-off points. Male patient, 49 years old. Thyroid ultrasound (US) with a suspicious nodule. Fine Needle Aspiration Biopsy (FNAB) suggests MTC, with pre-operative serum calcitonin (CTN) of 591 pg/mL. Total thyroidectomy with central and bilateral dissection was performed. Biopsy: MTC in left nodule of 26 mm without lymph nodes (LN) metastases. Follow-up with undetectable CTN for six years. After that, CT was 4.7 pg/mL, and carcinoembryonic antigen (CEA) was 1.2 ng/mL. Neck US showed bilateral LN. FNAB of LN does not show recurrence. A progressive rise of markers with doubling time of CTN and CEA was 16 and 51.3 months, respectively. CTN raised until 112 pg/mL. Given the lack of cervical compromise, a neck and lung CT, liver MRI, and bone scintigraphy were ordered despite CTN levels < 150 pg/mL. MRI showed hypervascular hepatic lesions, contrasted with gadoxetic acid. PET Ga68-DOTATATE showed lesions with overexpression of somatostatin receptors in the liver. Surgery was done, and a biopsy confirmed metastases. Conclusions: The clinical guidelines may allow the management of cases; however, they should be used considering each case context. In our patient, if the guidelines had been strictly followed, it would not have been possible to detect liver metastases to achieve a surgical resection with curative intent.

Paciente masculino, 49 años. Ecografía tiroidea con nódulo sospechoso. Biopsia por aspiración con aguja fina (PAAF) sugiere cáncer medular de tiroides (CMT), calcitonina sérica preoperatoria (CTN) de 591 pg/mL. Se realizó tiroidectomía total con disección central y bilateral. Biopsia: CMT en nódulo tiroideo izquierdo de 2,6 cm sin metástasis en 29 ganglios linfáticos (GL). En el seguimiento, CTN sérica indetectable durante 6 años. Posteriormente CTN sérica de 4,7 pg/mL y antígeno carcinoembrionario (CEA) de 1,2 ng/mL. Ecografía cervical de control mostró GL subcentimétricos bilaterales en grupo IV. PAAF de GL sin evidencia de malignidad, con niveles de CTN indetectables en la muestra. El doblaje de CTN y CEA fue 16 y 51,3 meses respectivamente. Dado ausencia de compromiso cervical, se solicitó TC de cuello y tórax, RM hepática y gammagrafía ósea, a pesar de no presentar niveles de CTN > 150 pg/mL. La RM mostró 3 lesiones hepáticas hipervasculares; se complementa con un PET Ga-DOTATATE que mostró 2 lesiones focales con sobreexposición de receptores de somatostatina en el parénquima hepático, con SUVmáx de 6,8 y 7,3. Se realiza cirugía extirpando 5 lesiones; la biopsia confirmó metástasis de CMT. Conclusiones: Las guías clínicas pueden dar orientaciones generales y permitir el manejo de casos basados en la evidencia; sin embargo, siempre deben usarse considerando el contexto de cada caso en particular. Si se hubieran seguido estrictamente las pautas, no habría sido posible detectar las metástasis hepáticas dentro de la ventana de oportunidad para lograr una resección quirúrgica con intención curativa.

Sintomas vocais, ansiedade e depressão pré e pós-tireoidectomia / Vocal symptoms, anxiety and depression pre and post thyroidectomy / Síntomas vocales, ansiedad y depresión pre y post tiroidectomía

Introdução: Alterações na tireoide e a tireoidectomia podem levar à sintomatologia vocal e emocional.Objetivo: Correlacionar sintomas vocais e traços de ansiedade e depressão pré e pós-tireoidectomia. Métodos: Estudo observacional, longitudinal. Participaram 20 pacientes submetidos à tireoidectomia, ao exame visual laríngeo e à Escala de Sintomas Vocais (ESV) e Escala Hospitalar de Ansiedade e Depressão (HADS) no pré-operatório, pós 1 semana e pós 3 meses, com média de idade de 54,5 anos, maior prevalência do sexo feminino (85%) e tireoidectomia parcial (70%). Resultados: Os pacientes autorreferiram sintomas vocais em todos os momentos, com maior frequência após uma semana e diferença significativa entre o domínio físico pré e pós 1 semana. Na HADS, observou-se maior escore total no pré-operatório e diferença significante nos três momentos, em todos os domínios, com maior diferença entre pré e pós 1 semana. Houve correlação positiva fraca entre os domínios limitação, emocional e escore total da ESV com a subescala de ansiedade pós 1 semana, entre o escore total da ESV e o escore total da HADS e correlação positiva moderada entre os domínios limitação e emocional da ESV com o escore total da HADS após uma semana. Conclusão: Pacientes submetidos à tireoidectomia autopercebem sintomas vocais e traços de grau leve de ansiedade tanto no pré quanto pós 1 semana e após 3 meses de cirurgia com pior autorreferência após uma semana. Quanto maior a autorreferência de sintomas vocais, mais traços de ansiedade o paciente pode apresentar. (AU)

Introduction: Thyroid alterations and thyroidectomy can lead to vocal and emotional symptoms.Purpose: To correlate vocal symptoms and anxiety and depression traits pre and post-thyroidectomy. Methods: Observational, longitudinal study. Participants were 20 patients who underwent thyroidectomy, laryngeal visual examination and the Voice Symptom Scale (VoiSS) and Hospital Anxiety and Depression Scale (HADS) preoperatively, 1 week and 3 months after, with a mean age of 54.5 years, higher prevalence of female gender (85%) and partial thyroidectomy (70%). Results: The patients self-reported vocal symptoms at all times, more frequently after one week and a significant difference between the physical domain pre and post 1 week. In HADS, there was a higher total score in the preoperative period and a significant difference in the three moments, in all domains, with a greater difference between pre and post 1 week. There was a weak positive correlation between the limitation, emotional and total score of the ESV domains with the anxiety subscale after 1 week, between the total score of the ESV and the total score of the HADS, and a moderate positive correlation between the limitation and emotional domains of the ESV with the HADS total score after one week. Conclusion: Patients undergoing thyroidectomy self-perceived vocal symptoms and mild anxiety traits both before and after 1 week and after 3 months of surgery with worse self-report after one week. The greater the self-report of vocal symptoms, the more traces of anxiety the patient may present. (AU)

Introducción: Cambios en la tiroides y tiroidectomía pueden provocar síntomas vocales y emocionales. Objetivo: Correlacionar síntomas vocales y rasgos de ansiedad y depresión antes y después de tiroidectomía. Metodos: Estudio observacional/longitudinal. Participaron 20 pacientes que se les realizó tiroidectomía, examen visual laríngeo, Escala de Síntomas Vocales (ESV) y Escala Hospitalaria de Ansiedad y Depresión (HADS) en preoperatorio, 1 semana y 3 meses después, con edad media de 54,5 años, prevalencia del género femenino (85%) y tiroidectomía parcial (70%). Resultados: Los pacientes informaron síntomas vocales en todo momento, con mayor frecuencia después de una semana y una diferencia significativa entre el dominio físico antes y después de 1 semana. En HADS, hubo mayor puntaje total en el preoperatorio y diferencia significativa en los tres momentos, con mayor diferencia entre pre y post 1 semana. Hubo una correlación positiva débil entre limitación, emocional y total de los dominios de la ESV con la subescala de ansiedad después de 1 semana, entre el total de la ESV y e total de la HADS, y una correlación positiva moderada entre la puntuación de limitación y dominios emocionales de la ESV con la puntuación total de HADS después de una semana. Conclusión: Los pacientes sometidos a tiroidectomía autopercibieron síntomas vocales y rasgos de ansiedad leve tanto antes como después de 1 semana y después de 3 meses de la cirugía con peor autoinforme después de una semana. Cuanto mayor es el autoinforme de síntomas vocales, más rastros de ansiedad puede presentar el paciente. (AU)

Utilidad de la medición de la hormona paratiroidea sérica como predictor de hipocalcemia posterior a tiroidectomía: Un estudio observacional de centro único / Utility of serum parathyroid hormone measurement as a predictor of post-thyroidectomy hypocalcemia: A single-center observational study

Introducción: La prevalencia del cáncer de tiroides es del 4 al 7%, en Ecuador alcanza una tasa de 16/100.000 habitantes, en la mayoría de casos requiere resolución quirúrgica asociando una tasa de complicaciones del 2 al 15%, de estas la hipocalcemia representa al menos el 10.9%. El objetivo del presente estudio fue evaluar la utilidad de la medición de la hormona paratiroidea sérica (PTH) como predictor de hipocalcemia posterior a tiroidectomía. Métodos: Se realizó un estudio transversal analítico de pacientes con tiroidectomía en el Hospital Metropolitano de Quito, en el periodo enero del 2017 a diciembre del 2019. Se analizaron variables demográficas, clínicas, quirúrgicas y complicaciones. Se comparó la relación de la PTH con la presencia de hipocalcemia clínica, serológica o ambas mediante RP, sensibilidad, especificidad, VPP, VPN, LR. Otras variables confusoras se analizaron mediante regresión logística multinomial comparando sus OR. Resultados: Se incluyeron 212 registros, 15.6% hombres y 84.4% mujeres, con promedio de 52.1 años. La indicación principal de tiroidectomía fue por Carcinoma papilar 123 (58.0%). Las complicaciones fueron el 22.7%. Un total de 48 pacientes desarrollaron hipocalcemia. Los niveles de PTH < 10 ng/l predicen la hipocalcemia con sensibilidad de 0.55, especificidad 0.78, VPP: 43%, VPN: 85%, RP fue 2.91 (IC 95% 1.06 - 8.01). Conclusiones: La cuantificación de PTH en 10 ng/l o menos, es útil para predecir hipocalcemia clínica en los pacientes sometidos a tiroidectomía total.

Introduction: The prevalence of thyroid cancer is from 4 to 7%; in Ecuador, it reaches a rate of 16/per 100,000 inhabitants; in most cases, it requires surgical resolution associated with a complication rate of 2 to 15%, of this hypocalcemia represents at least minus 10.9%. This study aimed to evaluate the usefulness of measuring serum parathyroid hormone (PTH) as a predictor of hypocalcemia after thyroidectomy. Methods: An analytical cross-sectional study of patients with thyroidectomy was carried out at the Metropolitan Hospital of Quito from January 2017 to December 2019. Demographic, clinical, surgical, and complication variables were analyzed. PTH's relationship with clinical or serological hypocalcemia or both was compared using PR, sensitivity, specificity, PPV, NPV, and LR. Other confounding variables were analyzed using multinomial logistic regression comparing their ORs. Results: A total of 212 records were included, 15.6% men and 84.4% women, with an average age of 52.1 years. The main indication for thyroidectomy was papillary carcinoma 123 (58.0%). Complications were 22.7%. A total of 48 patients developed hypocalcemia. PTH levels < 10 ng/l predict hypocalcemia with a sensitivity of 0.55, specificity of 0.78, PPV: 43%, NPV: 85%, and PR was 2.91 (95% CI 1.06 - 8.01). Conclusions: PTH quantification of 10 ng/l or less helps predict clinical hypocalcemia in patients undergoing total thyroidectomy.

Rehabilitación del nervio recurrente laríngeo postiroidectomía / Recurrent laryngeal nerve rehabilitation after thyroidectomy

El carcinoma papilar tiroideo es el tipo de cáncer más común de esta glándula, y su tratamiento de elección es la tiroidectomía. Entre las complicaciones asociadas resalta la parálisis de las cuerdas vocales, la cual ocurre por una lesión directa del nervio laríngeo recurrente durante la cirugía. Se presenta una paciente de 22 años de edad con este diagnóstico, a la cual se le realizó una tiroidectomía total; en el postoperatorio inmediato la paciente comenzó con estridor laríngeo intenso que requirió una traqueotomía de urgencia. En el examen físico se constató una parálisis bilateral de las cuerdas vocales y se decidió comenzar un tratamiento de rehabilitación del nervio recurrente laríngeo con laserterapia y HIVAMAT-200 como modalidades combinadas. Los resultados alcanzados con la fisioterapia fueron satisfactorios y la paciente se reintegró rápidamente a su ámbito familiar, escolar y social.

Papillary thyroid carcinoma is the most common type of cancer of this gland, and its treatment of choice is thyroidectomy. Vocal cord paralysis stands out among the associated complications, in which a direct injury to the recurrent laryngeal nerve occurs during surgery. We present a 22-year-old female patient with this diagnosis, who underwent a total thyroidectomy; in the immediate postoperative period the patient began with intense laryngeal stridor requiring an emergency tracheotomy. Physical examination revealed bilateral vocal cord paralysis and it was decided to begin rehabilitation treatment of the recurrent laryngeal nerve with laser therapy and HIVAMAT-200 as combined modalities. The results achieved with physiotherapy were satisfactory and the patient was quickly reintegrated into her family, school and social environment.

Características clínicas, epidemiológicas y quirúrgicas de pacientes con afecciones nodulares tiroideas / Clinical, Epidemiological and Surgical Characteristics of Patients with Thyroid Nodular Conditions

Introducción: En las últimas décadas la incidencia del cáncer tiroideo en el curso de la enfermedad nodular se ha incrementado debido a las novedosas técnicas de diagnóstico; sin embargo, la tasa de mortalidad se ha mantenido muy baja. Objetivo: Evaluar las características clínicas, epidemiológicas y quirúrgicas de pacientes con afecciones nodulares tiroideas. Métodos: Se realizó un estudio descriptivo observacional de cohorte prospectivo, longitudinal con los pacientes operados de afecciones tiroideas durante el período comprendido entre enero del 2008 y diciembre del 2018. El universo y la muestra quedaron constituidos por 467 pacientes que cumplieron con los criterios de inclusión. Resultados: Predominaron el sexo femenino (89,5 por ciento) y el grupo etario de 45-60 años (29,5 por ciento). Asociaron comorbilidades 338 pacientes y algún factor de riesgo de malignidad (6,2 por ciento). Un total de 174 pacientes manifestaron síntomas y 264 mostraron algún signo. Predominaron los reportes ecográficos (TI-RADS) y citológicos (Bethesda) tipo II (54,3 por ciento) y (55,5 por ciento), respectivamente. La hemitiroidectomía fue el procedimiento más realizado (59,9 por ciento) y la disfonía la complicación más encontrada (1,9 por ciento). Conclusiones: El diagnóstico oportuno del cáncer tiroideo en el curso de una enfermedad nodular contribuye a individualizar todas las decisiones terapéuticas atendiendo a las características de cada paciente y sus circunstancias(AU)

Introduction: In recent decades, the incidence rates of thyroid cancer in the course of nodular disease has increased due to novel diagnostic techniques; however, the mortality rate has remained very low. Objective: To evaluate the clinical, epidemiological and surgical characteristics of patients with nodular thyroid disease. Methods: A descriptive, observational, of prospective cohort, longitudinal and observational study was conducted with patients operated on for thyroid disorders during the period from January 2008 to December 2018. The study universe and sample consisted of 467 patients who met the inclusion criteria. Results: The female sex (89.5 percent) and the age group 45-60 years (29.5 percent) predominated. Comorbidities were present in 338 patients, as well as some risk factor for malignancy in 6.2 percent. A total of 174 patients manifested symptoms and 264 showed some sign. There was a predominance of echography (TI-RADS) and cytology (Bethesda) type II reports, accounting for 54.3 percent and 55.5 percent, respectively. Hemithyroidectomy was the most performed procedure (59.9 percent), while dysphonia was the most encountered complication (1.9 percent). Conclusions: Timely diagnosis of thyroid cancer in the course of nodular disease contributes to individualizing all therapeutic decisions considering the characteristics of each patient and their circumstances(AU)

A retrospective comparative study between robotic thyroidectomy through transoral vestibular approach and bilateral breast-axillary approach / 中华外科杂志

Objective: To compare the surgical outcome of robotic thyroidectomy through transoral approach and the bilateral breast-axillary approach. Methods: Retrospective analysis was made on the clinical data of patients who performed transoral robotic thyroidectomy (TORT group) or bilateral breast-axillary approach (BABA group) in the Department of Thyroid and Breast Surgery, the 960th Hospital of People's Liberation Army from July 2020 to May 2022. Both groups received lobectomy with lymph node dissection of the central region. A total of 100 cases were included in the study, including 48 cases in the TORT group and 52 cases in the BABA group. The propensity score matching method was used for 1∶1 matching of patients between the 2 groups, with a match tolerance of 0.03. There were 31 patients in each group successfully matched. In the TORT group, there were 5 males and 26 females, aged (33.2±7.9) years (range: 21 to 53 years). While there were 4 males and 27 females in the BABA group, aged (34.6±9.2) years (range: 19 to 58 years). The t test, Mann-Whitney U test, χ2 test or Fisher exact test were used to compare the clinical efficacy between the two groups. Results: All the patients successfully completed robotic thyroid surgery without conversion to open surgery. Compared with BABA group, the TORT group had longer operation time ((211.3±57.2) minutes vs. (126.2±37.8) minutes, t=6.915, P<0.01), shorter drainage tube retention time ((5.4±1.0) days vs. (6.4±1.2) days, t=-3.544, P=0.001), shorter total hospital stay ((6.6±1.2) days vs. (7.4±1.3) days, t=-2.353, P=0.022), and higher cosmetic score (9.46±0.25 vs. 9.27±0.26, t=2.925, P=0.005). There was no significant difference between the two groups in the number of lymph nodes dissection, metastasis in the central compartment, and the incidence of postoperative complications (all P>0.05). Conclusions: Compared with the bilateral breast-axillary approach, the transoral vestibular approach of robotic thyroidectomy is also safe and effective. It shows similar surgical results to the bilateral breast-axillary approach in strictly selected patients, but the postoperative recovery speed is much faster, and the hospital stay is shorter. Transoral robotic thyroidectomy is a more recommended surgical method for patients with high aesthetic demand.

"Graded early warning system" of RET germline mutation carriers in MEN2A/MEN2B families and total thyroidectomy (report of 7 cases) / 中华耳鼻咽喉头颈外科杂志

Objective: To explore the reasonable time of prophylactic thyroidectomy for RET gene carriers in multiple endocrine neoplasia(MEN) 2A/2B families. Methods: From May 2015 to August 2021, RET gene carriers in MEN2A/MEN2B families were dynamically followed up at the Department of Thyroid Head and Neck Surgery, Beijing Tongren Hospital of Capital Medical University. The high-risk patients were encouraged to undergo prophylacitc total thyroidectomy according to the principle of "graded early warning system", namely the evaluation of gene detection, calcitonin value and ultrasound examination successively. Seven cases underwent the surgery, including 3 males and 4 females, aged from 7 to 29 years. According to the risk stratification listed in the guidelines of the American Thyroid Association in 2015, there were 2 cases of the highest risk, 2 cases of the high risk and 3 cases of the modest risk. Calcitonin index remained within the normal range in 3 cases and elevated in 4 cases before operation. All 7 patients underwent thyroidectomy with lymph node dissection of the level Ⅵ performed in 4 patients. Results: The time from suggestion to operation was 2 to 37 months, with an average of 15.1 months. The 6 patients were medullary thyroid carcinoma and 1 case with C-cell hyperplasia. The follow-up time was 2 to 82 months, with an average of 38.4 months. Postoperative serum calcitonin levels of all cases decreased to normal level, with biochemical cure. There was no sign of recurrence on ultrasound examination. All 7 patients had no serious complications, no obvious thyroid dysfunction. Their height, weight and other indicators of pediatric patients were similar to those of their peers, with normal growth and development. Conclusion: For healthy people with MEN2A/MEN2B family history, prophylactic thyroidectomy can be carried out selectively based on the comprehensive evaluation of "graded early warning system" with strict screening and close monitoring.

Treatment duration of wrist-ankle acupuncture for relieving post-thyroidectomy pain: A randomized controlled trial / 中西医结合学报

BACKGROUND@#Treatment duration of wrist-ankle acupuncture (WAA) is uncertain for post-thyroidectomy pain relief.@*OBJECTIVE@#This study evaluated the effect of different WAA treatment duration on post-operative pain relief and other discomforts associated with thyroidectomy.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTION@#This randomized controlled trial was conducted at a single research site in Guangzhou, China. A total of 132 patients receiving thyroidectomy were randomly divided into the control group (sham WAA, 30 min) and three intervention groups (group 1: WAA, 30 min; group 2: WAA, 45 min; group 3: WAA, 60 min), with group allocation ratio of 1:1:1:1. Acupuncture was administered within 1 hour of leaving the operating room.@*OUTCOMES AND MEASURES@#Primary outcome was patients' pain at the surgical site assessed by visual analogue scale (VAS) at the moment after acupuncture treatment (post-intervention). Secondary outcomes included the patients' pain VAS scores at 6, 12, 24, 48 and 72 h after the thyroidectomy, the 40-item Quality of Recovery (QoR-40) score, the grade of post-operative nausea and vomiting (PONV), and the use of additional analgesic therapy.@*RESULTS@#The adjusted mean difference (AMD) in VAS scores from baseline to post-intervention in group 1 was -0.89 (95% confidence interval [CI], -1.02 to -0.76). The decrease in VAS score at post-intervention was statistically significant in group 1 compared to the control group (AMD, -0.43; 95% CI, -0.58 to -0.28; P < 0.001), and in groups 2 and 3 compared to group 1 (group 2 vs group 1: AMD, -0.65; 95% CI, -0.81 to -0.48; P < 0.001; group 3 vs group 1: AMD, -0.66; 95% CI, -0.86 to -0.47; P < 0.001). The VAS scores in the four groups converged beyond 24 h after the operation. Fewer patients in group 2 and group 3 experienced PONV in the first 24 h after operation. No statistical differences were measured in QoR-40 score and the number of patients with additional analgesic therapy.@*CONCLUSION@#Compared with the 30 min intervention, WAA treatment with longer needle retention time (45 or 60 min) had an advantage in pain relief within 6 h after surgery. WAA's analgesic effect lasted for 6-12 h post-operatively. Please cite this article as: Han XR, Yue W, Chen HC, He W, Luo JH, Chen SX, Liu N, Yang M.

Discussion on how to optimize active surveillance for low-risk papillary thyroid microcarcinoma in China / 中华外科杂志

Active surveillance, as a first-line treatment strategy for low-risk papillary thyroid microcarcinoma, has been recommended by guidelines worldwide. However, active surveillance has not been widely accepted by doctors and patients in China. In view of the huge challenges faced by active surveillance, doctors should improve their understanding of the "low risk" of papillary thyroid micropapillary cancer, identify some intermediate or high-risk cases, be familiar with the criteria and methods of diagnosis for disease progression, and timely turn patients with disease progression into more active treatment strategies. By analyzing the long-term cost-effectiveness of active surveillance, it is clear that medical expense is only one cost form of medical activities, and the health cost (thyroid removal and surgical complications) paid by patients due to"over-diagnosis and over-treatment" is the most important. Moreover, the weakening of the patients' social function caused by surgical procedures is a more hidden and far-reaching cost. The formulation of health economic policies (including medical insurance) should promote the adjustment of diagnosis and treatment behavior to the direction which is conducive to the long-term life and treatment of patients, improving the overall health level of society and reducing the overall cost. At the same time, doctors should stimulate the subjective initiative of patients, help them fully understand the impact of various treatment methods on their psychological and physical status, support patients psychologically, and strengthen their confidence in implementing active surveillance. By strengthening multi-disciplinary treatment team and system support, doctors can achieve risk stratification of papillary thyroid microcarcinoma, accurate judgment of disease progress, timely counseling for psychological problems, and long-term adherence to active surveillance. Improving the treatment level of advanced thyroid cancer is the key point of improve the prognosis. It is important to promote the development of active surveillance for low-risk papillary thyroid microcarcinoma. In the future, it is necessary to carry out multi-center prospective research and accumulate research evidence for promoting the standardization process of active surveillance. Standardized active surveillance will certainly benefit specific papillary thyroid microcarcinoma patients.

Objective:To explore the safety and feasibility of bilateral axillo-breast approach （BABA） robot in the operation of thyroid cancer in obese women. Methods:The clinical data of 81 obese female patients who underwent da Vinci robotic thyroid cancer surgery（robotic group） at the Department of Thyroid and Breast Surgery, PLA 960 Hospital from May 2018 to December 2021 were retrospectively analyzed and compared with the clinical data of 106 obese female thyroid cancer patients who underwent open surgery（open group） during the same period. The age, body mass index（BMI）, mean time of surgery, mean postoperative drainage, tumor diameter, postoperative tumor stage, number of lymph node dissection in the central and lateral cervical regions, number of positive lymph nodes in the central and lateral cervical regions, postoperative cosmetic outcome satisfaction score, mean postoperative hospital stay and postoperative complications of all patients were counted. The results were analyzed using SPSS 26.0 statistical software, and the count data were compared using the χ² test, and the measurement data were compared using the t test. Results:All patients completed the operation successfully, and there was no conversion in the robot group, postoperative pathological results were all composed of papillary thyroid carcinoma. The operation time in the robot group was（144.62±36.38） min, which was longer than that in the open group（117.06±18.72） min（P<0.05）. The average age of the robot group was（40.25±9.27） years, which was lower than that of the open group（49.59±8.70） years（P<0.05）. The satisfactory score of cosmetic effect in the robot group（9.44±0.65） was higher than that in the open group（5.23±1.07）（P<0.05）. There was no significant difference in tumor diameter, BMI, average postoperative drainage, temporary hypoparathyroidism and recurrent laryngeal nerve injury, number of central and lateral cervical lymph node dissection, number of positive lymph nodes in the central and lateral cervical regions, and average postoperative hospital stay between the two groups. There was no permanent hypoparathyroidism and recurrent laryngeal nerve injury in both groups. Conclusion:The application of BABA pathway robot in thyroid cancer surgery in obese women is safe and feasible, and the cosmetic effect is better after operation.

Predictive value of PTH level on day 1 after surgery for papillary thyroid carcinoma in patients with permanent hypoparathyroidism / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate the relationship between parathyroid hormone（PTH） level and permanent hypoparathyroidism（PHPP） on the first day after radical papillary thyroidectomy, and its predictive value. Methods:A total of 80 patients with papillary thyroid cancer who underwent total thyroid resection and central lymph node dissection were collected and analyzed from January 2021 to January 2022. According to whether PHPP occurred after surgery, the patients were divided into hypoparathyroidism group and normal parathyroid function group, and univariate and binary logistics regression were used to analyze the correlation between PTH and serum calcium levels and PHPP on the first day after surgery in two groups. The dynamic changes of PTH at different time points after operation were analyzed. The area under the receiver operating characteristic was used to evaluate the predictive power of PTH on the development of PHPP after surgery. Results:Among the 80 patients with papillary thyroid cancer, 10 cases developed PHPP, with an incidence rate of 12.5%. Binary logistics regression analysis showed that PTH on the first postoperative day（OR=14.534, 95%CI: 2.377-88.858, P=0.004） was an independent predictive risk factor for postoperative PHPP. Taking PTH=8.75 ng/L on the first postoperative day as the cut-off value, the AUC of the area under the curve was 0.874（95%CI: 0.790-0.958, P<0.001）, the sensitivity was 71.4%, the specificity was 100%, and the Yoden index was 0.714. Conclusion:PTH level on the first day after total thyroid papillary carcinoma surgery is closely related to PHPP, and is an independent predictor of PHPP.

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.

A comparative study for the efficacies of transaxillary non-inflatable endoscopic surgery versus traditional surgery for papillary thyroid carcinoma / 中华耳鼻咽喉头颈外科杂志

Objective: To compare the efficacies between open surgery and axillary non-inflatable endoscopic surgery in papillary thyroid carcinoma (PTC). Methods: A retrospective analysis was performed on 343 patients with unilateral PTC treated by traditional open surgery (201 cases) and transaxillary non-inflating endoscopic surgery (142 cases) from May 2019 to December 2021 in the Head and Neck Surgery of Sichuan Cancer Hospital. Among them, 97 were males and 246 were females, aged 20-69 years. 1∶1 propensity score matching (PSM) was performed on the enrolled patients, and the basic characteristics, perioperative clinical outcomes, postoperative complications, postoperative quality of life (Thyroid Cancer-Specific Quality of Life), aesthetic satisfaction and other aspects of the two groups were compared after successful matching. SPSS 26.0 software was used for statistical analysis. Results: A total of 190 patients were enrolled after PSM, with 95 cases in open group and 95 cases in endoscopic group. Intraoperative blood losses for endoscopic and open groups were [20 (20) ml vs. 20 (10) ml, M (IQR), Z=-2.22], postoperative drainage volumes [170 (70)ml vs. 101 (55)ml, Z=-7.91], operative time [135 (35)min vs. 95 (35)min, Z=-7.34], hospitalization cost [(28 188.7±2 765.1)yuan vs. (25 643.5±2 610.7)yuan, x¯±s, t=0.73], postoperative hospitalization time [(3.1±0.9)days vs. (2.6±0.9)days, t=-3.24], and drainage tube placement time [(2.5±0.8) days vs. (2.0±1.0)days, t=-4.16], with statistically significant differrences (all P<0.05). There was no significant difference in surgical complications (P>0.05). There were significant diffferences between two groups in the postoperative quality of life scores in neuromuscular, psychological, scar and cold sensation (all P<0.05), while there were no statistically significant differences in other quality of life scores (all P>0.05). In terms of aesthetic satisfaction 6 months after surgery, the endoscopic group was better than the open group, with statistically significant difference (χ2=41.47, P<0.05). Conclusion: Endoscopic thyroidectomy by a gasless unilateral axillary approach is a safe and reliable surgical method, which has remarkable cosmetic effect and can improve the postoperative quality of life of patients compared with the traditional thyroidectomy.
