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.

Esophageal intramural pseudodiverticulosis in a patient with food bolus impaction / Pseudodiverticulosis intramural esofágica en un paciente con impactación de bolo alimentario

Esophageal intramural pseudodiverticulosis is an uncommon esophageal benign disease. The typical finding during endoscopy is the presence of numerous pinhead-sized outpouchings along the esophageal wall. We reported a case of food bolus impaction secondary to esophageal intramural pseudodiverticulosis. A 67-year-old man presented with sudden-onset dysphagia. Multiple tiny orifices were revealed during upper endoscopy. In addition, there were an impacted food bolus and an esophageal web. The patient was treated with balloon dilatation and proton pump inhibitors. As a result the symptoms disappeared completely. Esophageal intramural pseudodiverticulosis is a rare cause of food bolus impaction and its treatment is directed towards the underlying associated conditions as well as the resolution of complications.

La pseudodiverticulosis intramural esofágica es una enfermedad benigna del esófago poco común. El hallazgo típico durante la endoscopia es la presencia de numerosos sáculos del tamaño de una cabeza de alfiler a lo largo de la pared esofágica. Reportamos un caso de impactación de bolo alimentario secundario a pseudodiverticulosis esofágica intramural. Un hombre de 67 años presentó disfagia de aparición repentina. Se encontraron múltiples orificios pequeños en la endoscopia superior. Además, hubo un bolo alimentario impactado y una red esofágica. El paciente fue tratado con dilatación con balón e inhibidores de la bomba de protones. Como resultado, los síntomas desaparecieron por completo. La pseudodiverticulosis intramural esofágica es una causa rara de impactación del bolo alimentario y su tratamiento se dirige a las condiciones asociadas subyacentes, así como a la resolución de complicaciones.

Imágenes en divertículos del tubo digestivo: localizaciones infrecuentes. serie de casos / Imaging in infrequent digestive diverticula: case series

Los divertículos se pueden localizar en todo el tubo digestivo (TD): esófago, estómago, duodeno, yeyuno, íleon, apéndice, colon. Son infrecuentes, salvo en colon. Sus manifestaciones clínicas son inespecíficas, con difícil diagnóstico y mayor riesgo de complicaciones. Se presenta una serie de divertículos digestivos atípicos, mostrando las características imagenológicas multimodalidad y describir los hallazgos claves. Es una revisión retrospectiva en el archivo computacional de nuestra institución. Selección de casos de divertículos de presentación inhabitual por sus características, localización u origen. En esófago los divertículos de Zenker y Killian-Jamieson. En estómago los divertículos gástricos infrecuentes. Los divertículos en intestino delgado tienen baja prevalencia, el más frecuente en duodeno. Los divertículos colónicos pueden tener una localización o presentación atípica. Los divertículos apendiculares y Meckel presentan baja prevalencia. Los divertículos digestivos son infrecuentes, excepto los colónicos. El radiólogo debe estar familiarizado con las diferentes ubicaciones de ellos, para reconocerlos y poder diagnosticarlos.

Diverticula may occur in any segment of the digestive tract: esophagus, stomach, duodenum, jejunum, ileum, appendix, and colon. Its clinical manifestations are nonspecifi which may turn diffiult an early diagnosis, leading to a higher risk of complications. We present a cases serie of atypical digestive diverticula and to describe the fidings on the different imaging techniques. We performed a retrospective review on the imaging computer archives of our institution. The atypical diverticula were selected. Zenker and Killian-Jamieson's diverticulums in esophagus. In stomach ocasionally gastric diverticula. Diverticula in small intestine have a low prevalence, the most common location is duodenum. Colonic diverticula may present a atypical location or presentation. The appendicular and Meckel diverticuli are uncommon. The digestive diverticula are uncommon, except the colonic ones. The radiologist must be familiar with it's different locations in order to be able to recognize it and diagnose it properly.

Diverticulo de esofago médio: relato de caso / Middle esophageal diverticulum: a case report

Introdução:Divertículos esofagianos são alterações esofá-gicas raras e podem ser classificados em proximais, médios ou distais, de acordo com a localização. Podem ser de pulsão ou tração e verdadeiro ou falso. Na dependência do tamanho do divertículo e da concomitância de doença associada, po-dem causar disfagia, regurgitação, mau hálito, rouquidão ou pneumopatias, podendo ter indicação de ressecção cirúrgica. O diagnóstico é suspeitado pela história clínica e confirmado pelo exame radiológico contrastado e pela endoscopia diges-tiva alta. Objetivo: Relatar o caso raro de uma paciente com divertículo de esôfago médio. Materiais e Métodos: Revisão do prontuário, registro fotográfico dos métodos diagnósticos e revisão da literatura. Resultados: Paciente feminina, 61 anos, encaminhada ao ambulatório do hospital de base de São José do Rio Preto, com queixa de disfagia progressiva para alimentos sólidos aproximadamente há cinco anos, associado à odinofagia, eructação intensa e perda ponderal nesse período de 10 quilos. A endoscopia digestiva alta, mostrou divertículo no terço médio do esôfago, 25 cm da arcada dentária supe-rior, com óstio de 3-4 cm de diâmetro e 3 cm de profundidade. A tomografia computadorizada de tórax confirmou a presen-ça do divertículo de esôfago em terço médio do esôfago, sem outros achados que justificassem sua presença. A paciente foi submetida à videotoracoscopia com ressecção do divertículo sem intercorrências. Atualmente, a paciente apresenta-se as-sintomática no acompanhamento clínico. Conclusão: Embora seja considerada uma alteração esofágica rara, os divertículos esofagianos, devem sempre ser considerados como diagnósti-co diferencial. Especialmente em casos de disfagia, halitose e enfermidades respiratórias por broncoaspiração. Em casos de pacientes sintomáticos e com dificuldade no tratamento clinico, a melhor opção terapêutica é a cirurgia com a excisão local do divertículo via toracotomia ou toracoscopia.

Introduction:Esophageal diverticula are rare conditions of the esophagus and can be classified according to their location in proximal, middle, or distal. Further categorization relates to presumed etiology, namely traction vs pulsion, true or false. Depending on the size of the diverticulum and the concomitance of associated disease, it can cause dysphagia, regurgitation, bad breath, hoarseness or pneumopathies. Thus, symptomatic patients are eligible surgical resection. The diagnosis is suspected by clinical history and confirmed by contrast radiological examination and upper digestive endoscopy. Objective: Present the case of a patient with middle esophageal diverticulum. Materials and Methods: We carried out a review of medical records, photographic record of diagnostic methods, and review from the literature. Results: A 61-year-old female patient was referred to the outpatient clinic at a teaching hospital (Hospital de Base), located in the city the São José do Rio Preto, inland of São Paulo State due to progressive complaints of dysphagia for solid foods for about 5 years, associated with odynophagia and severe eructation. She had a 10 kg weight loss in this period. Upper digestive endoscopy showed a diverticulum in the middle third of the esophagus, 25 cm from the dental arcade, with an ostium diameter of 3-4 cm and depth of 3 cm. A chest computed tomography confirmed the presence of an esophageal diverticulum in the middle third of the esophagus, in addition to other findings that justify its presence. She underwent video-assisted thoracoscopy with diverticulum resection without further complications. Currently, she is asymptomatic in clinical follow-up. Conclusion: Although it is considered a rare outgrowth, esophageal diverticula should always be considered as a differential diagnosis, especially in cases of dysphagia, halitosis, and respiratory diseases due to bronchoaspiration. In cases of symptomatic patients with difficulty to undergo clinical treatment, the best therapeutic option is a surgery with local excision of the diverticulum via thoracotomy or thoracoscopy.

[Concomitant pleural tuberculosis and aspiration pneumonia due to epiphrenic diverticula: a case report]

Aspiration pneumonia is a critical disease and can result from a various causes. Epiphrenic diverticula is a rare disorder, which can cause aspiration of food material contained in it. Mediastinal tuberculosis can also cause traction diverticula at mid-esophagus, which usually are asymptomatic and induce no complication. In this article we describe a case, suffering of all these three disorders and after seven years of surgery and medical treatment any symptom was not found in the patient
