Necrosis esofágica aguda (esófago negro) asociado a neoplasias digestivas / Acute esophageal necrosis (black esophagus) associated with digestive neoplasms

INTRODUCCIÓN. La necrosis esofágica aguda es un síndrome raro que se caracteriza endoscópicamente por una apariencia negra circunferencial irregular o difusa de la mucosa esofágica intratorácica, la afectación es generalmente del esófago distal y la transición abrupta de mucosa normal en la unión gastroesofágica, con extensión proximal variable. CASOS. Se presentan dos casos con diferentes comorbiliades, presentación de signos y síntomas, antecedentes y tratamiento, teniendo en común el diagnóstico a través de endoscopía digestiva alta. RESULTADOS. Caso clínico 1: tratamiento clínico basado en hidratación, suspensión de vía oral, omeprazol intravenoso y sucralfato; mala evolución clínica caracterizada por: disfagia, intolerancia oral y recurrencia del sangrado digestivo alto, se realiza colocación de gastrostomía endoscópica. Caso clínico 2: esófago con mucosa con fibrina y parches de necrosis extensa, se realiza compensación tanto de foco infeccioso pulmonar como hidratación y nutrición, en estudios complementarios se observa masa colónica, con estudio histopatológico confirmatorio de adenocarcinoma de colon en estado avanzado. DISCUSIÓN. La esofagitis necrotizante aguda es una entidad inusual, de baja prevalencia e incidencia, asociada con estados de hipoperfusión sistémica y múltiples comorbilidades que favorezcan un sustrato isquémico. Al revisar los reportes de casos que hay en la literatura médica, los casos que reportamos se correlaciona con las características clínicas, epidemiológicas, endoscópicas y factores de riesgo causales de la enfermedad. La presentación clínica más frecuente es el sangrado digestivo alto, que se debe correlacionar con el hallazgo endoscópico clásico. Nuestro primer caso reportado termina con la colocación de una gastrostomía para poder alimentarse. CONCLUSIÓN. El pronóstico de la necrosis esofágica aguda es malo y se requiere un alto índice de sospecha clínica y conocimiento de esta infrecuente patología para un diagnóstico temprano y un manejo oportuno. Se requiere una evaluación por endoscopia digestiva alta. Es una causa de sangrado gastrointestinal que conlleva tasas altas de mortalidad, principalmente en adultos mayores frágiles. El reconocimiento temprano y la reanimación agresiva son los principios fundamentales para un mejor resultado de la enfermedad.

INTRODUCTION. Acute esophageal necrosis is a rare syndrome that is characterized endoscopically by an irregular or diffuse circumferential black appearance of the intrathoracic esophageal mucosa, the involvement is generally of the distal esophagus and the abrupt transition of normal mucosa at the gastroesophageal junction, with variable proximal extension. CASES. Two cases are presented with different comorbidities, presentation of signs and symptoms, history and treatment, having in common the diagnosis through upper gastrointestinal endoscopy. RESULTS. Clinical case 1: clinical treatment based on hydration, oral suspension, intravenous omeprazole and sucralfate; poor clinical evolution characterized by: dysphagia, oral intolerance and recurrence of upper digestive bleeding, endoscopic gastrostomy placement was performed. Clinical case 2: esophagus with mucosa with fibrin and patches of extensive necrosis, compensation of both the pulmonary infectious focus and hydration and nutrition is performed, in complementary studies a colonic mass is observed, with a confirmatory histopathological study of colon adenocarcinoma in an advanced state. DISCUSSION. Acute necrotizing esophagitis is an unusual entity, with low prevalence and incidence, associated with states of systemic hypoperfusion and multiple comorbidities that favor an ischemic substrate. When reviewing the case reports in the medical literature, the cases we report correlate with the clinical, epidemiological, endoscopic characteristics and causal risk factors of the disease. The most common clinical presentation is upper gastrointestinal bleeding, which must be correlated with the classic endoscopic finding. Our first reported case ends with the placement of a gastrostomy to be able to feed. CONCLUSION. The prognosis of acute esophageal necrosis is poor and a high index of clinical suspicion and knowledge of this rare pathology is required for early diagnosis and timely management. Evaluation by upper gastrointestinal endoscopy is required. It is a cause of gastrointestinal bleeding that carries high mortality rates, mainly in frail older adults. Early recognition and aggressive resuscitation are the fundamental principles for a better outcome of the disease.

Reemplazo esofágico mínimamente invasivo con tubo de Akiyama en un paciente pediátrico con quemadura esofágica / Minimally invasive esophageal replacement with Akiyama tube in a pediatric patient with esophageal burn

Introducción. La ingesta de cáusticos continúa siendo un problema de salud pública en los países en vía de desarrollo, por lo que a veces es necesario realizar un reemplazo esofágico en estos pacientes. Aún no existe una técnica estandarizada para este procedimiento. Caso clínico. Masculino de 10 años con estenosis esofágica por ingesta de cáusticos, quien no mejoró con las dilataciones endoscópicas. Se realizó un ascenso gástrico transhiatal por vía ortotópica mediante cirugía mínimamente invasiva como manejo quirúrgico definitivo .Discusión. Actualmente existen varios tipos de injertos usados en el reemplazo esofágico. La interposición colónica y gástrica son las que cuentan con mayores estudios, mostrando resultados similares. Conclusiones. La elección del tipo y posición del injerto debe ser individualizada, tomando en cuenta las características de las lesiones y la anatomía de cada paciente para aumentar la tasa de éxito.

Introduction. The ingestion of caustics continues to be a public health problem in developing countries, which is why sometimes is necessary to perform an esophageal replacement in these patients. There is still no standardized technique for this procedure. Clinical case. A 10-year-old male with esophageal stricture due to caustic ingestion, who did not improve with endoscopic dilations. A laparoscopic transhiatal gastric lift was performed orthotopically as definitive surgical management using minimally invasive surgery. Discussion. Currently there are several types of grafts used in esophageal replacement. Colonic and gastric interposition are the ones that have the most studies, showing similar results. Conclusions. Choice of type and position of the graft must be individualized, taking into account the characteristics of the lesions and anatomy of each patient, in order to increase the success rate.

Síndrome de Boerhaave: manejo diagnóstico y terapéutico en el Hospital Regional de Talca / Boerhaave Syndrome: diagnostic and therapeutic management at the Hospital Regional de Talca

Introduction: Boerhaave syndrome is a spontaneous rupture of the esophageal wall caused by a sudden increase in intraesophageal pressure. It represents an incidence of approximately 15% of all esophageal perforations, which do not exceed 3.1 per 1 million inhabitants per year. Objectives: To communicate the clinical presentation and management of patients with this syndrome, as well as to reveal the different options available in our service for its treatment. Methods: Search in the statistical data of the regional Hospital of Talca for patients with a diagnosis of Boerhaave syndrome. Five patients were found. Information was obtained from their clinical records and is presented as a clinical case report with a descriptive analysis of their management. Results: Of the 5 clinical cases presented, a classic clinical presentation can be observed, most of the patients presented with vomiting that later evolved with thoracic and/or epigastric pain, associated with imaging studies suggesting esophageal perforation. Management was surgical in 100% of the cases, applying different techniques described in the literature. Discussion and Conclusion: Boerhaave syndrome is a medical-surgical emergency that requires timely management. In spite of the variety of management and the consequences of each one of them, all the patients had an evolution that allowed them to preserve their lives until nowadays. Keeping a high index of suspicion and choosing the best management will have an impact on morbidity and mortality.

Ulceración esofágica por ingestión de doxiciclina / Doxycycline induced esophageal ulceration

La ulceración esofágica por ingestión de doxiciclina es una de las causas más frecuentes de lesión esofágica. Ha sido subdiagnosticada y escasamente reconocida en dermatología. El dolor retroesternal, la odinofagia de aparición brusca y el antecedente de ingesta de doxiciclina u otros fármacos son características que facilitan su diagnóstico. Puede presentar complicaciones serias, como hemorragias, estenosis y mediastinitis.

Esophageal ulceration due to ingestion of doxycycline is one of the most frequent causes of esophageal injury. It has been underdiagnosed and scarcely recognized in dermatology. Retrosternal pain, sudden odynophagia and a history of doxycycline or other drugs intake are some of the characteristics that lead to diagnosis. It may cause severe complications such as bleeding, stenosis and mediastinitis.

Manometría de alta resolución en pacientes con trastornos motores esofágicos / High resolution manometry in patients with esophageal motor disorders

Introducción: La manometría de alta resolución es la prueba de referencia para el estudio de los trastornos motores esofágicos. Objetivo: Determinar la factibilidad de la manometría de alta resolución para el estudio de las características de los trastornos motores esofágicos. Métodos: Se realizó una investigación descriptiva, transversal, en el Centro Nacional de Cirugía de Mínimo Acceso, entre septiembre de 2018 y diciembre de 2019, en 56 pacientes cubanos con diagnóstico de trastorno motor esofágico por manometría de alta resolución, con edades entre 18 y 80 años, que dieron su consentimiento para participar en el estudio. Se excluyeron pacientes con acalasia esofágica y los trastornos menores de la peristalsis. Las variables incluidas fueron: edad, sexo, diagnósticos manométricos y sus características, síntomas, tipos de unión esofagogástrica, diagnósticos imagenológicos o endoscópicos. Para el análisis de los resultados se empleó el porcentaje, medidas de tendencia central y ji cuadrado de Pearson de homogeneidad, con un nivel de significación p 8804; 0,05 y 95 por ciento de confiabilidad. Resultados: Predominó la contractilidad ausente (39,28 por ciento), el sexo femenino (58,9 por ciento) y la disfagia (66,07 por ciento). A la obstrucción al flujo de la unión esofagogástrica correspondió la media de presión de reposo del esfínter esofágico inferior más alta (43,28 mmHg) y la media de la presión de relación integrada por encima de 15 mmHg (38,88 mmHg). El esófago hipercontráctil presentó media de contractilidad distal integrada elevada (5564,25 mmHg/s/cm). Se comprobó la existencia de contracciones rápidas en el espasmo esofágico distal (media de 21,4 cm/ s). Conclusiones: La manometría de alta resolución es factible de ser empleada para el diagnóstico de los trastornos motores esofágicos(AU)

Introduction: High-resolution manometry is the gold standard for the study of esophageal motor disorders. Objective: A descriptive, cross-sectional research was carried out in el Centro Nacional de Cirugía de Mínimo Acceso, between September 2018 and December 2019, in 56 patients, diagnosed with esophageal motor disorder by high-resolution manometry, aged between 18 and 20 years, who gave their consent to participate in the study. Esophageal achalasia and minor peristalsis disorders were excluded. The variables included were: age, sex, manometric diagnoses and their characteristics, symptoms, types of esophagogastric junction, imaging or endoscopic diagnoses. For the analysis of the results, the percentage, measures of central tendency and Pearson's chi square of homogeneity were used, with a level of statistical significance 8804; 0.05 and 95 percent reliability. Development: Absent contractility (39,28 percent), female sex (58,9 percent) and dysphagia (66,07 percent) predominated. The obstruction to the flow of the esophagogastric junction corresponded to the highest mean resting pressure of the lower esophageal sphincter (43,28 mmHg) and the mean integrated pressure ratio above 15 mmHg (38,88 mmHg). The hypercontractile esophagus presented mean high integrated distal contractility (5564,25 mmHg/s/cm). Rapid contractions were found in distal esophageal spasm (mean 21,4 cm/s). Conclusions: High resolution manometry was feasible to be used for the diagnosis of major esophageal motor disorders(AU)

Esofagite eosinofílica: uma revisão narrativa / Eosinophilic esophagitis: a narrative review

A esofagite eosinofílica (EoE) é uma doença inflamatória, crônica e recidivante do esôfago, caracterizada por inflamação com predomínio de eosinófilos e sintomas de disfunção esofágica. A doença, que representa a principal causa de disfagia crônica em crianças, jovens e adultos, compartilha intrínseca correlação com alergias, tanto em sua fisiopatologia, quanto em dados epidemiológicos e, recentemente, foi considerada uma manifestação tardia da marcha atópica em alguns indivíduos. O presente trabalho objetiva ampliar o conhecimento acerca da doença, visto que a EoE é uma patologia relativamente nova na história da medicina, e seu diagnóstico depende de elevada suspeição clínica. Além disso, por ser uma entidade com elevado potencial de causar impacto na qualidade de vida e repercussões fisiológicas, psicológicas e sociais para os pacientes, a suspeição e reconhecimento precoce da doença é essencial para que se institua a terapêutica adequada e obtenha-se controle sobre a progressão da doença.

Eosinophilic esophagitis (EoE) is an inflammatory, chronic, and recurrent esophageal disease characterized by inflammation with predominance of eosinophils and symptoms of esophageal dysfunction. The disease, which is the main cause of chronic dysphagia in children, young people, and adults, shares an intrinsic correlation with allergies, both in pathophysiology and in epidemiological data, and it was recently considered a late manifestation of the atopic march in some people. The present study aims to expand the knowledge about the disease, as EoE is a relatively new condition in the history of medicine and its diagnosis depends on high clinical suspicion. In addition, because EoE is an entity with a high potential to impact quality of life and cause physiological, psychological, and social repercussions for patients, suspicion and early recognition of the disease are essential for implementing an appropriate therapy and obtaining control over disease progression.

Introducción: Los tumores de esófago constituyen lesiones benignas o malignas, que afectan las diferentes capas del órgano. Objetivo: Caracterizar a pacientes con lesiones premalignas de esófago halladas en endoscopia bucal, según variables seleccionadas. Métodos: Se efectuó un estudio observacional, descriptivo y transversal en el Servicio de Gastroenterología del Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, durante el 2015. El universo estuvo constituido por 57 pacientes de 20 años y más, con diagnóstico endoscópico e histológico de lesión premaligna de esófago. Las variables analizadas fueron: edad, sexo, lesiones premalignas de esófago, grado de esofagitis y diagnóstico histológico. Resultados: La endoscopia mostró un predominio de la esofagitis por reflujo en los pacientes de 62 años y más (61,7 %), así como del grado A de la clasificación de los Ángeles en ambos sexos (39,7 y 30,1 % de mujeres y hombres, respectivamente). Según el diagnóstico histológico primaron la esofagitis crónica (48,4 %) y la esofagitis crónica con displasia (17,1 %). Conclusiones: La identificación de pacientes con lesiones premalignas de esófago constituye el punto de partida para futuras acciones preventivas e intervencionistas, con vistas a disminuir la incidencia del cáncer de esófago.

Introduction: The esophagus malignancies constitute benign or malignant lesions that affect the different layers of the organ. Objective: To characterize patients with esophagus premalignant lesions found in oral endoscopy, according to selected variables. Methods: An observational, descriptive and cross-sectional study was carried out in the Gastroenterology Service of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, during 2015. The universe was constituted by 57 patients aged 20 and over, with endoscopic and histologic diagnosis of esophagus premalignant lesion. The analyzed variables were: age, sex, esophagus premalignant lesions, degree of esophagitis and histologic diagnosis. Results: The endoscopy showed a prevalence of the esophagitis by reflux in patients aged 62 and over (61.7 %), as well as of the grade A of Los Angeles classification in both sexes (39.7 and 30.1% of women and men, respectively). According to the histologic diagnosis there was a prevalence of chronic esophagitis (48.4 %) and chronic esophagitis with dysplasia (17.1 %). Conclusions: The identification of patients with esophagus premalignant lesions constitutes the starting point for future preventive and interventionists actions, aimed at diminishing the incidence of esophagus cancer.

The dark side of the esophagus

Acute esophageal necrosis (AEN), also known as "black esophagus," is an entity characterized by the circumferential black appearance of esophageal mucosa, usually associated with hypoperfusion and gastric outlet obstruction. This entity has a reported prevalence of up to 0.2%, affecting predominantly elderly men with multiple comorbidities. Most cases resolve with conservative treatment with no need of surgical intervention. However, the overall prognosis is poor, with mortality reaching one-third of cases due to the patient's underlying illness. In this article we present three cases of patients with AEN.

Acute esophageal necrosis masquerading acute coronary syndrome

Acute esophageal necrosis (AEN) also known as "black esophagus" or "acute necrotizing esophagus" is a rare entity characterized by striking endoscopic findings of circumferential black coloring of the esophagus. AEN most frequently seen in the distal esophagus and can extend proximally along the entire esophagus. Characteristically, the circumferential black mucosa stops abruptly at the EGJ. AEN tends to present as acute upper gastrointestinal bleeding, though other symptoms including dysphagia and epigastric pain have been described. The etiology of AEN is multifactorial including a combination of ischemic insult, mucosal barrier defect, and a backflow injury of gastric secretions. Described is a case of AEN in a patient with history of uncontrolled diabetes who presented with an atypical chest pain mimicking acute coronary syndrome with negative subsequent cardiovascular workup.

Fish Bone Foreign Body: The Role of Imaging

Abstract Introduction Fish bone foreign body (FFB) impaction in the upper aerodigestive tract is a common cause for emergency department referral. Its management varies in both diagnosis and treatment paradigms. Fish bone foreign bodies are more commonly found in the oropharynx in cases of patients < 40 years old, and in the esophagus in cases of patients > 40 years old. Symptoms are typically non-indicative for the location of the FFB, with the exception of foreign body sensation at/superior to the cervical esophagus. A lack of findings during the physical examination is routinely followed by imaging, with computed tomography (CT) being the preferred modality. In practice, many patients undergo unnecessary imaging studies, including CT scans. Objectives To identify patients with suspected fish bone impaction who do not require CT imaging and can be safely discharged. Data Synthesis We have searched the PubMed database for the following medical subject headings (MeSH) terms: fish bone, fish foreign body AND oropharynx, hypopharynx, esophagus, flexible esophagoscopy, and rigid esophagoscopy. Our search in the English language yielded 32 papers. Case reports were included, since they highlighted rare and serious complications. Conclusion In patients > 40 years old suspected of fish bone impaction, noncontrast CT is recommended and should be urgently performed, even in the presence of ambiguous symptoms. However, in patients < 40 years old presenting within 24 hours from ingestion, imaging has little diagnostic value due to the low probability of esophageal fish bones. For this specific subgroup, in the absence of clinical findings, discharge without imaging studies may be considered safe. (AU)

Esófago negro: necrosis esofágica aguda. Serie de casos / Black esophagus: acute esophageal necrosis. Number of cases

La necrosis esofágica aguda, también conocida como esófago negro, es una patología poco común que se diagnostica mediante endoscopia que muestra una mucosa esofágica de aspecto negro. Presentamos 3 casos de necrosis esofágica aguda cuya patogénesis multifactorial correspondió a nuestros pacientes, especialmente la hipoperfusión; que es probablemente el factor clave de las lesiones esofágicas. Los pacientes presentaron las mismas características endoscópicas, y las biopsias esofágicas de 2 pacientes tenían un patrón histológico de inflamación severa y necrosis, uno de ellos asociado con infección micótica. Aunque la evolución fue favorable en todos, uno se complicó con estenosis esofágica

Acute esophageal necrosis also known as black esophagus is a rare disease diagnosed by endoscopy esophageal mucosa showing a black appearance. We present three cases of acute esophageal necrosis, the multifactorial pathogenesis was in our patients, especially hypoperfusion being probably the key factor for esophageal lesions. Patients had the same characteristics and samples endoscopic esophageal biopsies from two patients had a histological pattern of severe inflammation and necrosis, one associated with fungal infection. All had a favorable outcome, and presented as a complication esophageal stenosis in one of the cases presented.

Hematoma esofágico espontáneo: a propósito de un caso / Spontaneous esophagic hematoma: about a case

El dolor torácico es un motivo frecuente de consulta en los servicios de urgencias, sin embargo, el hematoma esofágico es una causa muy poco frecuente. Se manifiesta más frecuentemente en mujeres de edad media y avanzada, con una triada de dolor torácico súbito, disfagia u odinofagia y hematemesis. Presentamos un caso de una mujer de 89 años con antecedentes de hipertensión arterial en tratamiento, usuaria de antihipertensivos y aspirina, con una historia de dos días de evolución de dolor retroesternal, sensación febril, disnea y tos productiva secundario a un hematoma esofágico.

Thoracic pain is a frequent reason for consultation in the emergency department, however, esophageal hematoma is a very rare cause. It manifests more commonly in women of middle and advanced age, with a triad of sudden chest pain, dysphagia or odynophagia and hematemesis. We present a case of a 89 years old female patient, with a history of arterial hypertension in treatment, user of antihypertensive drugs and aspirin with a two day history of retrosternal pain, febrile sensation, dyspnea and productive cough due to a esophageal hematoma.

Correção cirúrgica de perfuração esofágica traumática por vídeo-toracoscopia utilizando patch de pleura parietal e músculo intercostal / Surgical correction of traumatic perforation by video-toracoscopy using patch of parietal pleura and intercostal muscle

Introdução: As lesões de esôfago são consideradas graves. Avanços técnicos permitiram aplicar técnicas de cirurgia minimamente invasiva nesse tipo de lesão. Relato de caso: mulher, 22 anos, vítima de perfuração por projétil de arma de fogo transfixante. Após avaliação inicial, foi submetida à toracostomia à direita por hemopneumotórax. No segundo dia de internamento, após o início da dieta por via oral, foi flagrada uma saída de secreção mucoide pelo dreno. A paciente foi submetida à videotoracoscopia à direita, sendo realizada sutura da lesão esofágica associada a patch de pleura parietal e músculo intercostal. Conclusão: a abordagem por videotoracoscopia mostra-se segura e eficaz.(AU)

Case report: Woman, 22 years old, victim of transfixing gunfire wound. After initial evaluation, patient was submitted to right thoracostomy due to hemopneumothorax. On the second day of hospitalization, after starting oral diet, the elimination of mucoid secretion from the chest drain was detected. Pacient underwent right-sided videothoracoscopy, in which suturing of an esophageal lesion was performed in association with a parietal pleura and intercostal muscle patch placement. Conclusion: Thoracoscopy approach is safe and effective.(AU)

Upper gastrointestinal alterations in kidney transplant candidates / Alterações digestivas altas em candidatos a transplante renal

ABSTRACT Introduction: The incidence of gastrointestinal disorders among patients with chronic kidney disease (CKD) is high, despite the lack of a good correlation between endoscopic findings and symptoms. Many services thus perform upper gastrointestinal (UGI) endoscopy on kidney transplant candidates. Objectives: This study aims to describe the alterations seen on the upper endoscopies of 96 kidney-transplant candidates seen from 2014 to 2015. Methods: Ninety-six CKD patients underwent upper endoscopic examination as part of the preparation to receive kidney grafts. The data collected from the patients' medical records were charted on Microsoft Office Excel 2016 and presented descriptively. Mean values, medians, interquartile ranges and 95% confidence intervals of the clinic and epidemiological variables were calculated. Possible associations between endoscopic findings and infection by H. pylori were studied. Results: Males accounted for 54.17% of the 96 patients included in the study. Median age and time on dialysis were 50 years and 50 months, respectively. The most frequent upper endoscopy finding was enanthematous pangastritis (57.30%), followed by erosive esophagitis (30.20%). Gastric intestinal metaplasia and peptic ulcer were found in 8.33% and 7.30% of the patients, respectively. H. pylori tests were positive in 49 patients, and H. pylori infection was correlated only with non-erosive esophagitis (P = 0.046). Conclusion: Abnormal upper endoscopy findings were detected in all studied patients. This study suggested that upper endoscopy is a valid procedure for kidney transplant candidates. However, prospective studies are needed to shed more light on this matter.

RESUMO Introdução: A incidência de doenças gastrointestinais altas em pacientes com doença renal crônica é elevada, porém não há boa correlação entre achados endoscópicos e sintomas. Assim, muitos serviços preconizam a realização de Endoscopia Digestiva Alta (EDA) nos candidatos a transplante renal. Objetivos: Descrever alterações endoscópicas presentes em 96 candidatos a transplante renal no período de 2014 a 2015. Métodos: Noventa e seis pacientes renais crônicos submetidos à EDA como preparo para transplante renal. Prontuários médicos dos pacientes foram revisados, os dados tabulados no programa Microsoft Office Excel 2016 e apresentados de maneira descritiva. Calculou-se média, mediana, intervalo interquartílico e intervalo de confiança de 95% das variáveis utilizadas. Alterações endoscópicas foram apresentadas quanto ao número, intervalo de confiança e valor de P, e correlacionadas com a presença ou ausência de infecção por Helicobacter pylori. Resultados: Dos 96 pacientes, 54,17% eram homens e 45,83% mulheres. As medianas de idade e tempo em diálise foram 50 anos e 50 meses, respectivamente. O achado mais comum na EDA foi pangastrite enantematosa (57,30%), seguida de esofagite erosiva (30,20%). Metaplasia intestinal gástrica e úlcera péptica foram encontradas em 8,33% e 7,30% dos pacientes, respectivamente. Pesquisa para H. pylori foi positiva em 49 pacientes, e somente houve correlação entre infecção por H. pylori e esofagite não erosiva (P = 0,046). Conclusão: Afecções gastrointestinais foram detectadas em todos os pacientes estudados. Os achados deste estudo sugerem que a realização de EDA em candidatos a receber transplante renal é desejável. Entretanto, estudos prospectivos são necessários para responder a esta questão.

Hemorragia masiva: una complicación tardía del reemplazo de la gastrostomía endoscópica percutánea. A propósito de un caso / Massive hemorrhage: a late complication of replacement percutaneous endoscopic gastrostomy: case report

La gastrostomía endoscópica percutánea (GEP) se utiliza como alternativa de la alimentación enteral/nasoenteral en situaciones en las que la alimentación por vía oral a largo plazo no es eficaz o no se tolera. Se prefiere principalmente en pacientes con afecciones neurológicas y, además, como apoyo de la nutrición en pacientes con enfermedades cardíacas congénitas, fibrosis quística, enfermedad intestinal inflamatoria y diversas enfermedades orofaríngeas. Si bien la colocación es sencilla en comparación con muchos procedimientos invasivos, presenta complicaciones, que incluyen desde la infección de la herida hasta la muerte. La GEP exige personal médico experimentado, antibióticos profilácticos adecuados e información exhaustiva para los pacientes o sus familias sobre el procedimiento y los cuidados posteriores. Presentamos una complicación rara, aunque importante, que surgió durante el reemplazo de la sonda de gastrostomía después del método de "corte y empuje". El tope, que debe llegar hasta el extremo distal del estómago, se desplazó hacia arriba, hasta el esófago proximal, y causó una úlcera profunda en la mucosa esofágica y una hemorragia masiva.

Percutaneous endoscopic gastrostomy (PEG) is used as an alternative to enteral/nasoenteral feeding in situations where long-term oral feeding is ineffective or not tolerated. It is mostly preferred in patients with neurological conditions and also to support nutrition in patients with congenital heart diseases, cystic fibrosis, inflammatory bowel disease, and various oropharyngeal diseases. Although it is easily applicable compared to many invasive procedures, it has complications ranging from wound infection to death. PEG requires experienced medical personnel, appropriate prophylactic antibiotics and exhaustive information to the patients or their families about the procedure and subsequent care. We present a rare but important complication during the replacement of the gastrostomy tube subsequent to the "cut and push" method. The bumper portions, which should move to the distal end of the stomach, moved upwards to the proximal esophagus, caused a deep ulcer in the esophageal mucosa and a massive hemorrhage.

Esophageal lichen planus: An unusual cause of dysphagia in the elderly / Líquen plano esofágico: uma causa incomum de disfagia em idosos

Summary An 82-year-old man sought our service with dysphagia and was referred for upper endoscopy with biopsies, which evidenced multiple ulcers of the esophagus and oropharinx. Histopathology confirmed the unusual diagnosis of esophageal lichen planus. The correct clinical suspicion of this disease can facilitate the diagnosis and guide specific treatment, which can drastically change the natural course of the disease.

Resumo Paciente do sexo masculino, de 82 anos, com disfagia, foi encaminhado para realização de endoscopia digestiva alta com biópsias, na qual foram evidenciadas múltiplas úlceras de esôfago e orofaringe. O estudo histopatológico confirmou o diagnóstico raro de líquen plano esofágico. A correta suspeita clínica dessa doença pode facilitar o diagnóstico e direcionar para um tratamento específico, o que pode drasticamente alterar o curso natural dessa comorbidade.
