ABSTRACT Purpose To identify the risk of dysphagia and its association with signs suggestive of sarcopenia, nutritional status and frequency of oral hygiene in the hospitalized elderly. Methods This is an analytical cross-sectional study with the participation of 52 elderly patients admitted to a medical clinic at a public hospital in the Federal District, Brazil. The Eating Assessment Tool, Strength, Assistance with walking, Rise from a chair, Climb stairs and Falls + Calf Circumference and the Mini Nutritional Assessment shortform were applied, in addition to the collection of sociodemographic data and health conditions. Results Among the elderly participants, 30.8% were at risk of self-reported dysphagia. The factors associated with the risk of dysphagia were: signs suggestive of sarcopenia (p=0.04), nutritional status (p<0.001) and oral hygiene frequency (p=0.03). Conclusion In the geriatric population of the present study, with the majority of the participants having tested positive for Covid-19, the risk of dysphagia was associated with signs suggestive of sarcopenia, nutritional status and frequency of oral hygiene.

Por que indivíduos saudáveis podem ter escores do Eating Assessment Tool (EAT-10) indicativos de disfagia? / Why healthy individuals may have Eating scores Assessment Tool (EAT-10) indicative of dysphagia?

Contexto: Eating Assessment Tool (EAT-10) é um método clínico de detecção de disfagia, entendida como dificuldade na deglutição. Em pesquisa realizada no Brasil, foi observado que 9,5% de indivíduos saudáveis assintomáticos têm resultados do teste compatível com disfagia. Objetivo: Avaliar os possíveis fatores que influenciam o resultado anormal do teste em indivíduos saudáveis. Método: Estudo transversal realizado na Faculdade de Medicina de Ribeirão Preto (FMRP-USP) em 358 voluntários sem doenças e sem sintomas, nos quais foi aplicado o teste EAT-10. Resultados: Em 316 o resultado nos 10 itens do teste foi zero, e em 42 os resultados da somatória dos 10 itens foi igual ou superior a 3, considerado indicativo de disfagia. O resultado ≥ 3 ocorreu em 10 homens entre 144 (7%) e 32 mulheres entre 214 (15%), (P = 0,01). A mediana (limites) de idades daqueles com resultado zero foi de 39 (20-84) anos, e com resultado ≥ 3 foi de 32 (20-83) anos (P = 0,04). O índice de massa corporal (IMC) não apresentou diferença entre pessoas com e sem indicação de disfagia. O máximo escore possível para o item 5 (dificuldade na ingestão de medicamentos) foi o que obteve o maior percentual (43,9%) de máximo escore possível, sendo o fator mais importante para o resultado anormal. Discussão: Em indivíduos saudáveis, a dificuldade em ingerir medicamentos foi o fator que mais influenciou a ocorrência de resultado do teste EAT-10 indicativo de disfagia. Conclusão: Dificuldade na ingestão de medicamentos sólidos deve ser considerada quando da interpretação do teste.

Exploring the Feasibility of a Comprehensive Screening for Voice and Swallowing Function in Post-Extubation Patients: A Pilot Study

Objectives: This pilot study aimed to identify and test a battery of time-efficient and cost-effective voice and swallowing screening tools for post-extubated patients in Chile. Methods: A panel of four experts selected and rated voice and swallowing screening tools. Seven measures were selected: smoothed cepstral peak prominence (CPPS) and maximum phonation time (MPT) for voice assessment, Volume-Viscosity Swallow Test (V-VST) for swallowing, voluntary and reflex peak cough flow for cough assessment, Eating Assessment Tool-10 (EAT-10), and Vocal Symptom Scale (VoiSS) for patient-reported outcomes. These tools were applied to four post-extubation patients within 48-72 hours post-hospital discharge, alongside the assessment of 17 matched controls. Results: Post-extubation patients showed significantly shorter MPT, lower CPPS values, increased V-VST dysphagia signs, reduced voluntary peak cough flow, and more pronounced symptoms on both the VoiSS and EAT-10 compared to controls. Limitations: The study had a modest sample size and relied solely on clinical screening tools. Value: This pilot study suggests a feasible and cost-effective approach to voice and swallowing screening for post-extubation patients, valuable in resource-constrained settings. Conclusion: While these accessible tools are not gold-standard assessments, they offer valuable insights and can guide future research. This study underscores the potential of selected tools in facilitating early detection of voice and swallowing disorders in post-extubation patients.

Objetivos: Este estudio piloto tuvo como objetivo identificar y probar una batería de herramientas de detección de problemas de voz y deglución que fueran eficientes en cuanto a tiempo y costo para pacientes chilenos postextubados. Métodos: Un panel de cuatro expertos seleccionó y evaluó herramientas de detección de voz y deglución. Se seleccionaron siete medidas: prominencia de pico cepstral suavizado (CPPS) y tiempo máximo de fonación (TMF) para la evaluación de la voz, prueba de volumen-viscosidad (V-VST) para la deglución, flujo máximo voluntario y reflejo de la tos para evaluar la tos, Eating Assessment Tool-10 (EAT-10) y la Escala de Sintomas Vocales (ESV) para los resultados informados por los pacientes. Estas herramientas se aplicaron a cuatro pacientes postextubados (48-72 horas), junto con la evaluación de 17 controles pareados. Resultados: Los pacientes postextubados mostraron un TMF y CPPS significativamente más bajos, aumento de los indicios de disfagia en la V-VST, reducción del flujo máximo de la tos y síntomas más pronunciados tanto en la ESV como en la EAT-10 en comparación con los controles. Limitaciones: El estudio tuvo un tamaño de muestra reducida y se basó únicamente en herramientas de detección clínica. Valor: Este estudio piloto sugiere un enfoque factible y rentable para la detección de problemas de voz y deglución en pacientes postextubados, valioso en entornos con recursos limitados. Conclusión: Aunque ese abordaje no sustituye a las evaluaciones de referencia, ofrece información valiosa y puede guiar futuras investigaciones que busquen facilitar la detección temprana de los trastornos de la voz-deglución en pacientes postextubados.

Acalasia o hipertrofia del músculo Cricofaríngeo: opciones de tratamiento

La disfagia alta es un síntoma frecuente de consulta al otorrinolaringólogo o gastroenteròlogo. Los diagnósticos diferenciales son trastornos de la deglución por daño neurològico, anillos esofágicos superiores, globus faríngeo, neoplasia, disfagia lusoria y trastornos motores inespecífico y otras más raras aún. Hay escasa literatura actualizada en pacientes adultos. El diagnóstico se basa en el estudio radiológico baritado, endoscopia y complementariamente con manometría. Las opciones de tratamiento son motivo de discusión, dada la poca evidencia disponible. En este artículo se presentan los resultados observados en una cohorte de 10 pacientes con diagnóstico confirmado de acalasia del cricofaríngeo sometidos a dilatación endoscópica (7 pacientes) o miotomía quirúrgica por cervicotomía (3 pacientes). Se evaluó evolución de la disfagia, complicaciones post procedimiento y resultados a largo plazo. No hubo complicaciones mayores, la disfagia mejoro en ambos grupos, en el grupo de dilatación se complementó el tratamiento con dilataciones periódicas en 2 pacientes. No hubo diferencias significativas en los 2 grupos estudiados. Conclusión: ambas opciones terapéuticas presentan buenos resultados en el tratamiento de estos pacientes.

Dysphagia at cervical level is a frequent symptom causing visit to otolaryngologist or gastroenterologist. The differential diagnoses are swallowing disorders due to neurological damage, upper esophageal rings, pharyngeal globus, neoplasia, non-specific motor disorders and other even rarer ones. There is little updated literature in adult patients. The diagnosis is based on the barium radiological study, endoscopy and complementary manometry. Treatment options are a matter of discussion, given the little evidence available. This paper presents the results observed in a cohort of 10 patients with a confirmed diagnosis of cricopharyngeal achalasia who underwent endoscopic dilation (7 patients) or surgical myotomy by cervicotomy (3 patients). The evolution of dysphagia, post-procedure complications and long-term results were evaluated. There were no major complications, dysphagia improved in both groups, in the dilation group the treatment was supplemented with periodic dilations in 2 patients. There were no significant differences in the 2 groups studied. Conclusion: both therapeutic options present good results in the treatment of these patients.

Self-expanding Metal Stents in Malignant Obstruction of the Esophagus: A 25-Year Multicentric Study

Background: Self-expanding metal prostheses improve dysphagia in patients with incurable esophageal cancer (EC). New stents have been introduced, and chemoradiotherapy has been implemented for EC, changing patients' risk profiles. It is unknown whether this has affected palliation with stents. Patients and methods: Retrospective study in three centers in Medellín-Colombia; patients undergoing placement of palliative esophageal prostheses for malignant dysphagia (1997-2022). Major and minor complications after implantation, the influence of oncological therapies, and survival were evaluated for 1997-2009 (n = 289) and 2010-2022 (n = 318). Results: 607 patients underwent esophageal prostheses; 296 (48.8%) became complicated. It was higher in the second period (52.5% vs. 48.1%), as were major complications (20.8% vs. 14.2%, p = 0.033), with no differences in minor complications (33.9% vs 31.8%, p = 0.765). Also, 190 (31.3%) patients presented with recurrent dysphagia, stable in both periods. Migration increased over time (from 13.1% to 18.2%, p = 0.09). The most common minor adverse event was pain, increasing over time (from 24.9% to 33.95%, p < 0.01), and associated factors were chemoradiotherapy, absence of fistula, and squamous cell carcinoma. Acid reflux decreased in the second group (p = 0.038). Twelve percent of patients required another intervention for feeding. Survival was not impacted by time and use of stents. Conclusions: Stents are an alternative in non-surgical malignant dysphagia, although recurrent dysphagia has not decreased over time. Minor stent-related complications are increasing in association with the implementation of chemoradiotherapy.

Antecedentes: Las prótesis metálicas autoexpandibles mejoran la disfagia en pacientes con cáncer esofágico (CE) incurable. En las últimas décadas se han introducido nuevos tipos de stents y se ha implementado la quimiorradioterapia para el CE, generando cambios en los perfiles de riesgo de los pacientes. Se desconoce si estos cambios han afectado la paliación con stents. Pacientes y métodos: Estudio retrospectivo en tres centros de Medellín-Colombia; pacientes sometidos a colocación de prótesis esofágicas paliativas para disfagia maligna (1997-2022). Se evaluaron en dos períodos: 1997-2009 (n = 289) y 2010-2022 (n = 318), complicaciones mayores y menores después del implante, la influencia de las terapias oncológicas y la sobrevida. Resultados: Se evaluaron 607 pacientes sometidos a prótesis esofágicas. 296 (48,8%) se complicaron, y fue mayor en el segundo periodo (52,5% frente a 48,1%), al igual que las complicaciones mayores (20,8% frente a 14,2%, p = 0,033), sin diferencias en complicaciones menores (33,9% frente a 31,8%, p = 0,765). 190 (31,3%) pacientes presentaron disfagia recurrente, estable en ambos períodos. La migración aumentó con el tiempo (de 13,1% a 18,2%, p = 0,09). El evento adverso menor más frecuente fue dolor, que aumentó con el tiempo (de 24,9% a 33,95%, p < 0,01), y los factores asociados fueron quimiorradioterapia, ausencia de fístula y carcinoma de células escamosas. El reflujo ácido disminuyó en el segundo grupo (p = 0,038). El 12% de pacientes requirieron otra intervención para alimentarse. No se impactó la sobrevida con el tiempo y uso de stents. Conclusiones: Los stents son una alternativa en la disfagia maligna no quirúrgica, aunque la disfagia recurrente no ha disminuido con el tiempo. Las complicaciones menores relacionadas con el stent van en aumento, asociadas a la implementación de la quimiorradioterapia.

Herpes Simplex Virus Esophagitis in an Immunocompetent Patient

We present the case of a 17-year-old patient with no known comorbidity or history who was admitted due to dysphagia. Endoscopy revealed ulcerated lesions in the distal esophagus that were positive for herpes simplex virus type 1 (HSV-1) on immunohistochemistry. An examination of HSV-1 esophagitis in the immunocompetent patient is made.

Se presenta el caso de un paciente de 17 años sin ninguna comorbilidad ni antecedente conocido que ingresó por disfagia. La endoscopia reveló lesiones ulceradas en el esófago distal que resultaron positivas para virus del herpes simple tipo 1 (VHS-1) en la inmunohistoquímica. Se hace una revisión de la esofagitis por VHS-1 en el paciente inmunocompetente.

Evaluating the Efficacy and Safety of Laparoscopic Heller Myotomy in Treating Achalasia

Introduction: Laparoscopic Heller myotomy (LHM) is widely recognized as the standard surgical treatment for esophageal achalasia. However, there is a lack of local data regarding the clinical characteristics of patients and the outcomes of this intervention. Methodology: This retrospective study analyzed patients who underwent LHM over an eight-year period. Demographic, operative, and postoperative variables were assessed. The Eckardt score was used to compare symptoms before and after the intervention. Continuous variables were presented as means. Results: Among the 39 patients assessed, 27 met the inclusion criteria. Of these, 51% were male, with an average age of 48 years. The average lower esophageal sphincter pressure was 36 mmHg. The mean operative time and bleeding were 133 minutes and 34 mL, respectively. The average length of the myotomy was 8.3 cm. Partial fundoplication was performed in all cases, and intraoperative endoscopy was conducted in 88% of the cases. Two intraoperative mucosal perforations occurred. The average length of hospital stay was 2.7 days. There was one medical complication but no mortality. Dysphagia significantly improved by 95%, and the mean Eckardt score decreased from 7.7 to 1.2 after surgery (p < 0.001). The average follow-up period was 24 months. Conclusion: LHM with partial fundoplication proves to be an effective and safe procedure for treating achalasia. It results in the resolution of dysphagia in 95% of cases and carries minimal morbidity. Therefore, LHM should be considered the definitive treatment of choice for achalasia.

Introducción: la miotomía de Heller laparoscópica (MHL) se considera el tratamiento quirúrgico estándar en acalasia esofágica. A nivel local se desconocen las características clínicas de los pacientes y los resultados de la intervención. Metodología: estudio retrospectivo que incluye pacientes llevados a MHL durante un periodo de 8 años. Se analizaron variables demográficas, operatorias y posoperatorias. Mediante el puntaje de Eckardt se compararon síntomas antes y después de la intervención. Las variables continuas se expresan en promedios. Resultados: 27 de 39 pacientes cumplieron los criterios de inclusión. El 51% fueron hombres y el promedio de edad fue de 48 años. La presión promedio del esfínter esofágico inferior fue de 36 mm Hg. El promedio de tiempo operatorio y sangrado fue de 133 minutos y 34 mL, respectivamente. La longitud promedio de la miotomía fue de 8,3 cm. Se adicionó funduplicatura parcial en todos los casos y en el 88% se realizó una endoscopia intraoperatoria. Se presentaron 2 perforaciones intraoperatorias de la mucosa. El promedio de estancia hospitalaria fue 2,7 días. Hubo una complicación médica y ninguna mortalidad. La disfagia mejoró en el 95% y el promedio del puntaje de Eckardt disminuyó de 7,7 a 1,2 luego de cirugía (p < 0,001). El seguimiento fue de 24 meses en promedio. Conclusión: la MHL con funduplicatura parcial es un procedimiento efectivo y seguro para el tratamiento de la acalasia. Se asocia a resolución de la disfagia en el 95% de los casos, su morbilidad es mínima y debe considerarse el tratamiento definitivo de elección.

Characterization of Achalasia Subtypes Based on High-Resolution Manometry in Patients at a Reference Hospital in Colombia

Introduction: Limited information is available regarding the clinical and manometric characteristics of different subtypes of achalasia. This study aims to describe these characteristics in patients treated at a prominent hospital in Colombia. Methods: This descriptive observational study included patients diagnosed with achalasia using high-resolution esophageal manometry at Hospital Universitario San Ignacio in Bogotá, Colombia, between 2016 and 2020. We documented the clinical manifestations, manometric findings, treatment approaches, and response to treatment based on the subtype of achalasia. Results: A total of 87 patients were enrolled, with a median age of 51 years, and 56.4% of them were female. The majority had type II achalasia (78.1%), followed by type I (16%) and type III (5.7%). All patients presented with dysphagia, 40.2% experienced chest pain, and 27.6% had gastroesophageal reflux. The clinical parameters, including integrated relaxation pressure value (IRP; median: 24 mmHg, interquartile range [IQR]: 19-33), upper esophageal sphincter pressure (UES; median: 63 mmHg, IQR: 46-98), and lower esophageal sphincter pressure (LES; median: 34 mm Hg, IQR: 26-45), were similar across the different subtypes. Esophageal clearance was incomplete in all patients. Among the 35 patients who received intervention, Heller's myotomy was the most commonly employed procedure (68.5%), followed by esophageal dilation (28.6%). All patients experienced symptomatic improvement, with a median pre-treatment Eckardt score of 5 (IQR: 5-6) and a post-treatment score of 1 (IQR: 1-2). Conclusions: Type II achalasia is the most prevalent subtype. The clinical and manometric findings, as well as treatment response, exhibit similarities among the different subtypes of achalasia. In Colombia, the outcomes of this condition align with those reported in other parts of the world.

Introducción: existe información limitada sobre las características clínicas y manométricas de los diferentes subtipos de acalasia. Este estudio describe dichas características en pacientes manejados en un hospital de referencia en Colombia. Método: estudio descriptivo observacional que incluye a pacientes con diagnóstico de acalasia por manometría esofágica de alta resolución manejados en el Hospital Universitario San Ignacio de Bogotá, Colombia, entre 2016 y 2020. Se describen las manifestaciones clínicas, hallazgos manométricos, tratamiento utilizado y respuesta al mismo según el subtipo de acalasia. Resultados: se incluyeron a 87 pacientes (mediana de edad: 51 años, 56,4% mujeres). La mayoría de tipo II (78,1%), seguido por tipo I (16%) y tipo III (5,7%). Todos presentaron disfagia, 40,2% dolor torácico y 27,6% reflujo gastroesofágico. La clínica y los valores del integral de presión de relajación (IRP; mediana: 24 mm Hg, rango intercuartílico [RIC]: 19-33), presión del esfínter esofágico superior (EES; mediana: 63 mm Hg, RIC: 46-98) y presión del esfínter esofágico inferior (EEI; mediana: 34 mm Hg, RIC: 26-45) fueron similares en los diferentes subtipos. El aclaramiento esofágico fue incompleto en todos los pacientes. Entre 35 pacientes que recibieron manejo intervencionista, la miotomía de Heller fue la intervención más utilizada (68,5%), seguido por la dilatación esofágica (28,6%). La totalidad de estos pacientes presentó una mejoría sintomática con la mediana de Eckardt pretratamiento de 5 (RIC: 5-6) y postratamiento de 1 (RIC: 1-2). Conclusiones: la acalasia tipo II es la más común. La clínica y los hallazgos manométricos y respuesta a tratamiento son similares entre los subtipos de acalasia. En Colombia, esta entidad se comporta de forma similar a lo reportado en otras partes del mundo.

A Truncus Bicaroticus and an Aberrant Right Subclavian Artery. A Rare Case and Literature Review / Un Tronco Bicarótico y una Arteria Subclavia Derecha Aberrante. Un Caso Raro y Revisión de la Literatura

SUMMARY: An aberrant right subclavian artery described by David Bayford, is rare and one of the aortic arch anomalies. It gives usually incidental findings. We present the case of a 57-year-old woman who was admitted to a neurology outpatient clinic due to a headache and no obvious pathology was detected during a physical examination. In consequence of the brain and chest CT angiography, incidental anomalies of the aortic arch branches were found and asymptomatic aberrant right subclavian artery and bicarotid trunk was diagnosed. The presence of this anomaly is becoming increasingly important in avoiding vascular injuries and cerebral complications in patients undergoing endovascular intervention on the aorta aortic arch surgery, thyroidectomy, or cervicothoracic surgery. So, detailed knowledge of variations of the subclavian artery and bicarotid trunk is paramount for radiologists and surgeons operating on the region of the anterior neck.

Una arteria subclavia derecha aberrante descrita por David Bayford, es rara y es una de las anomalías del arco aórtico. Además, suele ser hallazgos accidentales. Presentamos el caso de una mujer de 57 años que ingresó a una consulta de neurología por dolor de cabeza, sin embargo, no se le detectó patología evidente al examen físico. En el angio-TC de cerebro y tórax, se encontraron anomalías incidentales de las ramas del arco aórtico y se diagnosticó arteria subclavia derecha aberrante asintomática y tronco bicarotídeo. Determinar la presencia de esta anomalía es cada vez más importante, para así evitar lesiones vasculares y complicaciones cerebrales en pacientes sometidos a intervención endovascular de la aorta, cirugía del arco aórtico, tiroidectomía o cirugía cervicotorácica. Por lo tanto, el conocimiento detallado de las variaciones de la arteria subclavia y el tronco bicarotídeo es primordial para los radiólogos y cirujanos que operan en la región anterior del cuello.

Linfangioma hipofaríngeo en adulto: presentación de un caso clínico

Los linfangiomas son malformaciones linfáticas benignas infrecuentes; se manifiestan principalmente en la infancia. Pueden desarrollarse en cualquier zona del cuerpo, más frecuentemente cabeza y cuello, siendo su compromiso faríngeo extremadamente poco común. Dada su clínica inespecífica se requiere un análisis anatomopatológico preciso para concretar un correcto diagnóstico. Presentamos el caso de una mujer de 40 años con historia de disfagia y odinofagia de un año de evolución cuyo estudio imagenológico y con nasofibroscopía evidenció un tumor redondeado alojado en seno piriforme derecho, la biopsia excisional confirmó el diagnóstico de linfangioma. Se debe considerar el diagnóstico de linfangioma dentro de los diagnósticos diferenciales de tumores en faringe y concientizar su presencia en pacientes adulto, para ofrecer el manejo óptimo basado, ya sea en escisión quirúrgica completa, para evitar la recurrencia asociado, o al uso de sustancias esclerosantes.

Lymphangiomas are infrequent benign lymphatic malformations, with clinical manifestations mainly at birth or in childhood. They can develop in any area of the body, most frequently the head and neck, and their pharyngeal involvement is extremely rare. Given its nonspecific symptoms, it requires a precise pathological analysis to make a correct diagnosis. We present the case of a 40-year-old woman with a 1-year history of dysphagia and odynophagia whose imaging study and nasofibroscopy revealed a rounded tumor lodged in the right pyriform sinus. The excisional biopsy confirmed the diagnosis of lymphangioma. The diagnosis of lymphangioma should be considered within the differentials of tumors in the pharynx and awareness of its presence in adults to offer optimal management based on complete surgical excision to avoid recurrence or management with use of sclerosing substances.

Abstract Objective To evaluate swallowing-related quality of life in hospitalized elderly patients. Methods Cross-sectional analytical and observational approach was used in our study. Fifty-two elderly patients in a medical clinic of a public hospital in Distrito Federal [Federal District] participated. In addition to collecting sociodemographic and health condition data, the Eating Assessment Tool and the swallowing-related quality of life Questionnaire were applied. Results Of the elderly participants, 30.8% had a self-reported risk of dysphagia. The elderly at risk for dysphagia had lower scores in the "eating duration" domain and higher scores in the "mental health" domain. The only domain in which there was no statistical difference in the response pattern of the participants who were, or were not at risk for dysphagia was the "sleep domain." Among the variables of the 11 domains of the Swallowing Quality of Life Questionnaire, mostly positive correlations were found, with different degrees. Conclusion The swallowing-related quality of life of hospitalized elderly patients is directly manifested as decreased social interaction, increased eating time, fear to eat, and swallowing as a burden.

Medidas de prevenção da progressão da disfagia em pacientes com câncer de cabeça e pescoço submetidos a radioterapia: uma revisão sistemática com meta-análise / Preventive measures for the progression of dysphagia in patients with cancer of head and neck subjected to radiotherapy: a systematic review with meta-analysis

RESUMO Objetivo Identificar os efeitos de medidas profiláticas, não farmacológicas, sobre a progressão da disfagia em pacientes com câncer de cabeça e pescoço submetidos a radioterapia. Estratégia de pesquisa A busca foi realizada nas bases de dados Medline (via PubMed), Scopus e Embase, assim como na literatura cinzenta. Critérios de seleção Foram incluídos ensaios clínicos randomizados, com pacientes adultos (≥ 18 anos) e diagnóstico de câncer de cabeça e pescoço, tratados com radioterapia (associada ou não à cirurgia e quimioterapia) submetidos a protocolos não farmacológicos de prevenção da disfagia. Análise dos dados O risco de viés foi avaliado por meio da escala PEDRO e a qualidade global da evidência foi avaliada de acordo com o instrumento GRADE. Resultados Foram considerados elegíveis 4 estudos, e desses, dois foram incluídos na metanálise. O resultado favoreceu o grupo intervenção, com diferença média de 1,27 [IC 95%: 0,74 à 1,80]. Houve baixa heterogeneidade e a pontuação média para risco de viés foi de 7,5 de um total de 11 pontos. A falta de detalhamento nos cuidados com os vieses de seleção, performance, detecção, atrito e de relato contribuíram para o julgamento da qualidade da evidência, considerada baixa. Conclusão Medidas profiláticas de contenção da disfagia podem promover importantes benefícios sobre a ingesta oral dos pacientes com câncer de cabeça e pescoço, quando comparados aqueles que não realizaram tal medida terapêutica ao longo da radioterapia.

ABSTRACT Purpose To identify the effects of prophylactic, non-pharmacological measures on the progression of dysphagia in patients with head and neck cancer undergoing radiotherapy. Research strategies The search was performed in Medline (via PubMed), Scopus, and Embase databases, as well as in the gray literature. Selection criteria Randomized clinical trials were included, with adult patients (≥ 18 years old) and diagnosed with head and neck cancer, treated with radiotherapy (with or without surgery and chemotherapy), and submitted to non-pharmacological protocols for the prevention of dysphagia. Data analysis The risk of bias was assessed using the PEDRO scale and the overall quality of evidence was assessed using the GRADE instrument. Results Four studies were considered eligible, and of these, two were included in the meta-analysis. The result favored the intervention group, with a mean difference of 1.27 [95% CI: 0.74 to 1.80]. There was low heterogeneity and the mean score for risk of bias was 7.5 out of 11 points. The lack of detail in the care with selection, performance, detection, attrition, and reporting biases contributed to the judgment of the quality of the evidence, considered low. Conclusion Prophylactic measures to contain dysphagia can promote important benefits on the oral intake of patients with head and neck cancer when compared to those who did not undergo such a therapeutic measure during radiotherapy.

Laparoscopic antireflux surgery: were old questions answered? partial or total fundoplication? / Cirurgia laparoscópica antirrefluxo: perguntas antigas foram respondidas? fundoplicatura parcial ou total?

ABSTRACT Laparoscopic total fundoplication is currently considered the gold standard for the surgical treatment of gastroesophageal reflux disease. Short-term outcomes after laparoscopic total fundoplication are excellent, with fast recovery and minimal perioperative morbidity. The symptom relief and reflux control are achieved in about 80 to 90% of patients 10 years after surgery. However, a small but clinically relevant incidence of postoperative dysphagia and gas-related symptoms is reported. Debate still exists about the best antireflux operation; during the last three decades, the surgical outcome of laparoscopic partial fundoplication (anterior or posterior) were compared to those achieved after a laparoscopic total fundoplication. The laparoscopic partial fundoplication, either anterior (180°) or posterior, should be performed only in patients with gastroesophageal reflux disease secondary to scleroderma and impaired esophageal motility, since the laparoscopic total fundoplication would impair esophageal emptying and cause dysphagia.

RESUMO A fundoplicatura total laparoscópica é considerada, atualmente, o padrão ouro para o tratamento cirúrgico da doença do refluxo gastroesofágico. Os resultados de curto prazo após a fundoplicatura total laparoscópica são excelentes, com recuperação rápida e morbidade perioperatória mínima. O alívio dos sintomas e o controle do refluxo são alcançados em cerca de 80 a 90% dos pacientes, 10 anos após a cirurgia. No entanto, é relatada uma incidência pequena, mas clinicamente relevante, de disfagia pós-operatória e sintomas relacionados a gases. Ainda existe debate sobre a melhor operação antirrefluxo e, nas últimas três décadas, os resultados cirúrgicos da fundoplicatura parcial laparoscópica (anterior ou posterior) foram comparados aos obtidos após uma fundoplicatura total laparoscópica. A fundoplicatura parcial laparoscópica, seja anterior (180°) ou posterior, deve ser realizada apenas em pacientes com doença do refluxo gastroesofágico secundária a esclerodermia e motilidade esofágica ineficiente, pois uma fundoplicatura total laparoscópica prejudicaria o esvaziamento esofágico e causaria disfagia.

Estudio de prevalencia de lesiones laríngeas y disfagia en pacientes críticos traqueostomizados por COVID-19 / A Study on the Prevalence of Laryngeal Injuries and Dysphagia in Critically Ill Tracheostomized Patients due to COVID-19

Introducción: Los pacientes con neumonía grave por COVID-19 pueden requerir intubación orotraqueal, ventilación mecánica prolongada y traqueostomía. La presencia de la vía aérea artificial puede generar lesiones laríngeas y estar asociada a disfunción deglutoria con aumento del riesgo de aspiración. Objetivo: Describir la prevalencia de lesiones laríngeas y disfagia orofaríngea en los pacientes críticos traqueostomizados por COVID-19. Como objetivo secundario, evaluar la asociación entre la presencia de lesión laríngea y disfagia y de cada una de ellas con antecedentes del paciente, duración de la vía aérea artificial y maniobra de decúbito prono. Material y métodos: Estudio observacional, longitudinal y retrospectivo, realizado en el hospital Juan A. Fernández, CABA, Argentina. Se incluyeron de manera consecutiva pacientes con diagnóstico de COVID-19 traqueostomizados. La presencia de lesiones laríngeas y disfagia se valoró mediante estudio endoscópico de la deglución al momento de la decanulación. Resultados: Se analizaron 32 pacientes, de los cuales, 28 (87,5%) evidenciaron al menos una lesión laríngea, principalmente en la región glótica. La prevalencia de disfagia fue de 65,6% (21/32). No se encontró asociación significativa entre lesiones laríngeas y disfagia (p = 0,70). Conclusión: En esta cohorte de pacientes, las lesiones laríngeas y la disfagia fueron altamente prevalentes. La evaluación precoz mediante endoscopia de la deglución nos ha facilitado un diagnóstico oportuno para guiar el tratamiento de manera individual hasta la decanulación y resolución de la disfagia encontrada.

Introduction: Patients with severe pneumonia due to COVID-19 may require orotracheal intubation, prolonged mechanical ventilation and tracheostomy. The presence of an artificial airway can generate laryngeal lesions and it is associated with swallowing dysfunction and increased risk of aspiration. Objective: The main objective of this study is to describe the prevalence of laryngeal lesions and oropharyngeal dysphagia in critically ill tracheostomized patients due to COVID-19. As a secondary objective, is to evaluate the association between the presence of laryngeal injury and dysphagia and each of them with other variables related to the patient's history, duration of the artificial airway and the prone position maneuver. Methods: This is an observational, longitudinal and retrospective study, conducted at the Juan A Fernández Hospital, CABA, Argentina. Tracheostomized patients diagnosed with COVID-19 were consecutively included. The presence of laryngeal lesions and dysphagia was recorded by fibroscopic evaluation of swallowing at the time of decannulation. Results: 32 patients were analyzed, of which 28 (87.5%) showed at least one laryngeal lesion, mainly in the glottic region. The prevalence of dysphagia was 65.6% (21/32). No significant association was found between laryngeal injuries and dysphagia (p = 0.70). Conclusion: laryngeal injuries and dysphagia were highly prevalent in this cohort of patients. The early evaluation through fibroscopic evaluation of swallowing for the protocolized follow-up of these patients, has provided us a timely diagnosis to guide treatment individually until decannulation and resolution of the dysphagia found.

Comprometimento da qualidade de vida em pacientes com acalásia chagásica e fatores clínicos associados / Impaired quality of life in chagas acalasia patients and associated clinical factors

ABSTRACT Background: No study has focused on Health-Related Quality of Life (HRQoL) for Chagas Achalasia patients. Objective: To compare HRQoL between Chagas Achalasia patients and the general population; and to correlate HRQoL with clinical factors that can affect it. Methods: Sixty Chagas Achalasia patients and 50 controls were evaluated. All patients underwent esophageal manometry for the diagnosis of achalasia and esophagogram to determine the grade of megaesophagus. Three questionnaires were used: 1) clinical: the following data were collected: demographic, medical history, body mass index, occurrence of six esophageal symptoms (Esophageal Symptom Score: number of symptoms reported by patients), duration of dysphagia; 2) socio-economic-cultural status evaluation: patients and controls answered seven questions about their socio-economic-cultural conditions; 3) HRQoL: the validated Brazilian-Portuguese version of the Short-form Health Survey (SF-36) questionnaire (license QM020039) was used. It measures health in eight domains: 3a) four physical: physical functioning, role limitations relating to physical health, bodily pain, and general health perception; 3b) four mental: vitality, social functioning, role limitations relating to emotional health, and mental health. These domains can be summarized into Physical and Mental Summary scores. We analyzed correlations between SF-36 Physical/Mental Summary Component scores and the following clinical factors: Esophageal Symptom Score, duration of dysphagia, body mass index, grades of megaesophagus (defined by the esophagogram) and presence/absence of megacolon (defined by opaque enema). Results: Patients and controls had similar age, gender, medical history, and socio-economic-cultural lifestyles (P>0.05). All patients had dysphagia and megaesophagus. SF-36 scores were significantly lower in Chagas Achalasia patients than controls for all eight domains (physicals: P<0.002; mentals: P<0.0027). The Physical and Mental Summary Component scores were also lower in Chagas Achalasia patients than controls (P<0.0062). For patients, the Physical Summary score was negatively correlated to Esophageal Symptom Score (P=0.0011) and positively correlated to body mass index (P=0.02). No other correlations were found. Conclusion: Chagas Achalasia patients have an impaired HRQoL in all physical and mental domains. Patients reporting more symptoms had worse physical domains. Patients with higher body mass index had better physical domains.

RESUMO Contexto: Não encontramos na literatura estudos sobre a qualidade de vida em pacientes com acalásia chagásica especificamente. Objetivo: Comparar a qualidade de vida de pacientes com acalásia chagásica e a da população em geral. Também, correlacionar a qualidade de vida nestes pacientes com fatores clínicos que possam afetá-la. Métodos: Estudamos 60 pacientes com acalásia chagásica e 50 controles. Todos os pacientes foram submetidos à manometria esofágica para diagnóstico de acalásia e esofagograma técnica padrão para determinar o grau do megaesôfago. Usamos 3 questionários: 1) clínico: foram coletados os seguintes dados: demográficos, história clínica, índice de massa corporal, presença de seis sintomas esofágicos (definimos Escore de Sintomas Esofágicos como o número de sintomas relatados pelos pacientes), duração da disfagia; 2) avaliação sócio-econômico-cultural: sete questões sobre as condições sócio-econômico-culturais foram perguntadas para pacientes e controles; 3) qualidade de vida: foi avaliada pelo questionário SF-36, versão validada para o português-Brasil (licença QM020039). Este é um questionário genérico que mede a qualidade de vida em oito domínios: 3a) quatro físicos: capacidade funcional, aspectos físicos, dor corporal, estado geral de saúde; 3b) quatro mentais: vitalidade, aspectos sociais, aspectos emocionais, saúde mental. Estes oito domínios podem ser compilados em dois escores: Sumário dos Escores Físicos e Sumário dos Escores Mentais. Na análise de fatores clínicos que pudessem afetar a qualidade de vida dos pacientes, avaliamos: escores de sintomas esofágicos, duração da disfagia, índice de massa corporal, graus de megaesôfago e presença/ausência de megacólon. Resultados: Os dois grupos (pacientes e controles) apresentaram semelhantes idade, gênero, história médica e condições socioeconômico-culturais (P>0,05). Todos os pacientes tinham disfagia e megaesôfago. Com relação à qualidade de vida, pacientes com acalásia chagásica apresentaram valores significativamente menores do que os controles em todos os domínios do questionário SF-36 (domínios físicos: P<0,002; domínios mentais: P<0,0027). Os Sumários dos Escores Físicos e Mentais também foram significativamente menores em pacientes do que nos controles (P<0.0062). A análise dos fatores clínicos que poderiam afetar a qualidade de vida nos pacientes mostrou que o Sumário dos Escores Físicos se correlaciona negativamente com o Escores Dos Sintomas Esofágicos (P=0,0011) e positivamente com o índice de massa corporal (P=0,02). Não observamos qualquer outra correlação. Conclusão: Pacientes com Acalásia Chagásica têm pior qualidade de vida que a população em geral, em todos os domínios físicos e mentais. Pacientes que relataram mais sintomas apresentaram pior qualidade de vida nos domínios físicos. Pacientes com valores maiores de índice de massa corporal apresentaram melhor qualidade de vida nos domínios físicos.

Esophageal Intramural Pseudodiverticulosis / Pseudodiverticulosis intramural del esófago

Abstract A report of two cases of esophageal intramural pseudodiverticulosis, a very unusual disease, with other 240 cases reported in the entire world literature since 1960. Its etiology and pathogenesis are still not fully understood. However, it is believed that hypertrophy of the submucosal glands, with chronic inflammation, fibrosis, and consequent esophageal stenosis, causes dysphagia, which is the primary manifestation of esophageal intramural pseudodiverticulosis. The main diagnostic methods include the radiological examination of the esophagus with barium contrast (esophagogram) and esophagogastroduodenoscopy (EGD). Both reported cases were treated with endoscopic dilation, exemplifying the safety and efficacy of this therapeutic option for treating dysphagia in these individuals.

Resumen Reporte de dos casos de pseudodiverticulosis esofágica intramural, una enfermedad muy inusual, con otros 240 casos reportados en toda la literatura mundial desde 1960. Su etiología y patogenia aún no se conocen completamente; sin embargo, se cree que existe una hipertrofia de las glándulas submucosas, con inflamación crónica, fibrosis y consecuente estenosis esofágica, lo que provoca disfagia, que es la principal manifestación de la pseudodiverticulosis esofágica intramural. El examen radiológico del esófago con contraste de bario (esofagograma) y la endoscopia digestiva alta (EDA) son los principales métodos de diagnóstico. Ambos casos reportados se trataron con dilatación endoscópica, lo que ejemplifica la seguridad y eficacia de dicha opción terapéutica para el tratamiento de la disfagia en estos individuos.

Resumen Introducción: las dificultades en la comprensión de las indicaciones sobre las dietas de textura modificada según la severidad de la disfagia por parte de pacientes y sus cuidadores, influyen negativamente en la adherencia y aumentan la morbimortalidad de los pacientes. La explicación escrita o verbal, no sería suficiente requiriendo recursos adicionales basados en imágenes y/o la realización de demostraciones prácticas. Por lo mencionado, se diseñó el instrumento audiovisual NutriDis®. Objetivos: determinar la validez aparente, de contenido y la factibilidad de un instrumento audiovisual basado en los descriptores de la "International Dysphagia Diet Standardisation Initiative" (IDDSI). Materiales y método: se utilizó la técnica Delphi por juicio de expertos, incluyendo a nutricionistas, kinesiólogos y fonoaudiólogos. En la primera ronda participaron 19 expertos y 9 en la segunda. Se determinó el grado de acuerdo entre éstos, a través del coeficiente V de Aiken para cada nivel de IDDSI y a nivel global. Resultados: el instrumento resultó presentar validez de contenido y el grado de acuerdo global aumentó entre la primera y la segunda ronda desde 90,8 a 94,1%, clasificándose como adecuado. El nivel IDDSI 4 presentó el máximo acuerdo e IDDSI 1 el menor. Conclusiones: según la opinión de expertos en el área, la herramienta audiovisual NutriDis®, presentó una validez de contenido adecuada en promedio y calificado globalmente como excelente por la mayoría. Se destaca que el instrumento es inédito, representando un gran desafío su desarrollo.

Abstract Introduction: patients and caregivers find it difficult to understand the indications of modified texture diets following dysphagia severity, and this negatively influences adherence and increases patient morbidity and mortality. The written or verbal explanation would not be enough, and additional resources based on images and / or the realization of practical demonstrations are required. As a result, the NutriDis® audiovisual tool was designed. Objectives: to determine the apparent and content validity and feasibility of an audiovisual tool based on the descriptors of the "International Dysphagia Diet Standardization Initiative" (IDDSI). Materials and method: the Delphi technique was used following experts judgment, including nutritionists, speech therapists and kinesiologists. 19 experts participated in the first round and 9 in the second. The degree of agreement among them was determined through Aiken's V coefficient for each level of IDDSI and also at global level. Results: the tool turned out to be valid and the degree of global agreement increased between the first and second rounds from 90, 8 % to 94,1%, classifying as adequate. Level IDDSI 4 presented the highest agreement and IDDSI 1 the lowest. Conclusions: according to the opinion of experts in the area, the NutriDis® audiovisual tool presented an adequate content validity on average and was globally rated as excellent by the majority. It is highlighted that the tool is unprecedented and its development represented a great challenge.

A propósito de un caso: divertículo de Kommerell / About a case: Kommerell's diverticulum

La presencia de sibilantes refractarios y localizados en una sola área de auscultación en los adultos, sobre todo si están acompañados de anormalidades espirométricas y radiológicas, son a menudo la expresión clínica de una condición que requiere un proceso diagnóstico más profundo, más allá del facilista diagnóstico de asma. Entre estas anomalías se encuentran los anillos vasculares como el divertículo de Kommerel, que es una variante con una prevalencia muy baja y se caracteriza por la presencia de un arco aórtico derecho con una salida de la arteria subclavia izquierda aberrante y que provoca síntomas por la compresión de las estructuras adyacentes a estas. Aportamos en este caso clínico, el proceso diagnóstico de uno de estos hallazgos incidentales: la presencia de sibilantes localizados en una paciente joven, asintomática con una espirometría alterada que podría hacernos sospechar la presencia de broncomalacia, una aspiración de cuerpo extraño, un proceso infeccioso, tumoral o un anillo vascular que pasó desapercibido hasta la edad adulta.

The presence of refractory and localized wheezing in a single area of auscultation in adults, especially if they are accompanied by spirometric and radiological abnormalities, are often the clinical expression of a condition that requires a deeper diagnostic process, beyond the easy diagnosis of asthma. Among these abnormalities are vascular rings such as Kommerell¨s diverticulum, which is a very low prevalence variant and it is characterized by the presence of a right aortic arch with an aberrant exit from the left subclavian artery and that causes symptoms due to compression of the adjacent structures. In this clinical case, we provide the diagnosis process of one of these incidental findings, such as the presence of localized wheezing in a young asyntomatic patient with altered spirometry that could lead us to suspect the presence of bronchomalacia, foreign body aspiration, an infection, tumor or vascular ring that went unnoticed until adulthood.
