Caso clínico-radiológico: divertículo de Zenker / Clinical-radiological case: Zenker's diverticulum

Zenker's diverticulum develops in the hypopharynx, usually between the cricopharyngeus muscle and the inferior pharyngeal constrictor muscle, at the level of the C5 and C6 vertebrae. It often manifests clinically with dysphagia, persistent reflux, and halitosis. Its reference diagnosis is through barium video swallowing observed by fluoroscopy. Management is surgical with a cervical or transoral approach, the latter having a better safety profile

Lesão transfixante de carótida por espinha de peixe - relato de caso / Carotid artery perforation by fish bone - a case report

Abstract Accidental fish bone ingestion is a common complaint at emergency departments. The majority of cases have a benign course. However, serious complications such as esophagus perforation, cervical vessel injury and cervical abscess can occur in 7.4% of cases. Mortality rates can be as high as 50% when mediastinitis occurs. We report a case of an esophageal perforation caused by a fish bone with a lesion to the right common carotid artery after 20 days of evolution. Surgical exploration occurred with corrections of the lesion in the right common carotid and esophagus. Early identification of this kind of injury is paramount to prevent potentially fatal complications.

Esophageal manometry in systemic sclerosis: findings and association with clinical manifestations

SUMMARY INTRODUCTION Systemic sclerosis (SSC) is an autoimmune disorder that affects several organs of unknown etiology, characterized by vascular damage and fibrosis of the skin and organs. Among the organs involved are the esophagus and the lung. OBJECTIVES To relate the profile of changes in esophageal electromanometry (EM), the profile of skin involvement, interstitial pneumopathy (ILD), and esophageal symptoms in SSC patients. METHODS This is an observational, cross-sectional study carried out at the SSC outpatient clinic of the Hospital de Clínicas of the Federal University of Uberlândia. After approval by the Ethics Committee and signed the terms of consent, 50 patients were initially enrolled, from 04/12/2014 to 06/25/2015. They were submitted to the usual investigations according to the clinical picture. The statistical analysis was descriptive in percentage, means, and standard deviation. The Chi-square test was used to evaluate the relationship between EM, high-resolution tomography, and esophageal symptoms. RESULTS 91.9% of the patients had some manometric alterations. 37.8% had involvement of the esophageal body and lower esophageal sphincter. 37.8% had ILD. 24.3% presented the diffuse form of SSC. No association was found between manometric changes and clinical manifestations (cutaneous, pulmonary, and gastrointestinal symptoms). CONCLUSION The present study confirms that esophageal motility alterations detected by EM are frequent in SSC patients, but may not be related to cutaneous extension involvement, the presence of ILD, or the gastrointestinal complaints of patients.

RESUMO INTRODUÇÃO A esclerose sistêmica (ES) é uma doença autoimune que afeta vários órgãos de etiologia desconhecida, caracterizada por dano vascular e fibrose da pele e órgãos. Entre os órgãos envolvidos estão o esôfago e o pulmão. OBJETIVOS Relacionar o perfil das alterações na eletromanometria (ME), o perfil de acometimento da pele, a pneumopatia intersticial (PI) e os sintomas esofágicos em pacientes com ES. MÉTODO Trata-se de um estudo observacional, transversal, realizado no ambulatório de SSC do Hospital das Clínicas da Universidade Federal de Uberlândia. Após aprovação pelo Comitê de Ética e assinatura dos termos de consentimento, 50 pacientes foram inicialmente convidados, de 04/12/2014 a 25/06/2015. Eles foram submetidos às investigações usuais de acordo com o quadro clínico. A análise estatística foi descritiva em porcentagem, média e desvio padrão. O teste Qui-quadrado foi utilizado para avaliar a relação entre ME, tomografia de alta resolução e sintomas esofágicos. RESULTADOS 91,9% dos pacientes apresentaram alterações manométricas. 37,8% tinham envolvimento do corpo esofágico e do esfíncter esofágico inferior. 37,8% tinham IP. 24,3% apresentaram a forma difusa da ES. Não há associação entre alterações manométricas e manifestações clínicas (sintomas cutâneos, pulmonares e gastrointestinais). CONCLUSÃO O presente estudo confirma que as alterações da motilidade esofágica detectadas pela EM são frequentes em pacientes com SSC, mas podem não estar relacionadas ao envolvimento cutâneo, à de DPI ou às queixas gastrointestinais dos pacientes.

Vomiting in newborns as a result of a duodenal membrane: two case reports / Episódios de vômitos em recém-nascidos como consequência de membrana duodenal: relatos de dois casos

ABSTRACT Vomiting episodes in newborns are extremely common and often attributed to gastroesophageal reflux. The symptoms of vomiting, however, may be caused by other complications. In this report, we present two cases of a 1-month-old male and a 2-month-old female, both presenting vomiting episodes that led to malnutrition. Some pediatricians often attribute the diagnosis of gastroesophageal reflux to newborns that are vomiting; however, there is a portion of the population that has other causes that lead to similar symptoms. The pediatrician should be alert to the clinical signs of weight loss, dehydration and malnutrition to investigate other causes of vomiting.

RESUMO Episódios de vômito em recém-nascidos são extremamente comuns e frequentemente atribuídos a refluxo gastresofágico. Os sintomas de vômito, no entanto, podem ser causados por outras complicações. Neste relato, apresentamos dois casos: um lactente masculino, com 1 mês de idade, e um feminino, com 2 meses, ambos apresentando episódios de vômitos que levaram à desnutrição. Alguns pediatras costumam atribuir o diagnóstico de refluxo gastresofágico a recém-nascidos que estão vomitando; mas parcela da população tem outras causas que levam a sintomas semelhantes. O pediatra deve estar atento aos sinais clínicos de perda de peso, desidratação e desnutrição, para investigar outras causas de vômitos.

Enfrentamiento de la ingesta de cuerpo extraño en un Hospital Regional del sur de Chile / Management of foreign body ingestion at a Regional Hospital in southern Chile

Introducción: La ingesta de cuerpos extraños (ICE) es frecuente en pediatría y puede llevar a complicaciones. Nuestro objetivo es revisar la experiencia de nuestro centro en el manejo de estos pacientes y proponer un protocolo de tratamiento. Material y Método: Estudio transversal retrospectivo, observacional y descriptivo, en el cual se revisaron los informes endoscópicos y fichas de pacientes con diagnóstico de ICE manejados por la Unidad de Endoscopia Pediátrica del Hospital Clínico Regional de Concepción entre enero de 2013 y junio de 2017 (53 meses), totalizando 40 casos. El registro y análisis de los datos se realizó con Microsoft® Excel 2016® para MacOS®. Resultados: El promedio de edad fue de 3,96 ± 3,24 años. La moda estadística fue de 2 años. A todos los pacientes se les realizó una endoscopia digestiva alta. El CE más frecuente fue la moneda (61,9%). En 6 casos (14,2%) fue una pila de botón. La retención de CE fue en tercio proximal del esófago (30,9%), el cuerpo gástrico (26,2%) y el tercio distal del esófago (14,2%), extrayéndose principalmente con pinza de cuerpo extraño (90,4%). El 57,5% evidenció alguna lesión relacionada a la ubicación del CE, siendo la más grave la producida por pila de botón. Conclusión: La ICE en niños es una entidad potencialmente peligrosa, por lo que se hace necesario disponer de una unidad de endoscopia pediátrica y protocolos de manejo para evitar complicaciones, sobre todo con objetos de alto riesgo.

Introduction: Foreign body ingestion (FBI) is common in pediatrics and can lead to complications. The aim of the present study is to review the experience of our center in the management of these patients and to propose a treatment protocol. Material and Method: Retrospective, observational and descriptive cross-sectional study, in which the endoscopic reports and records of patients diagnosed with IFB managed by the Pediatric Endoscopy Unit of the Regional Clinical Hospital of Concepción between January 2013 and June 2017 (53 months) were reviewed, with a total of 40 cases. Data recording and analysis was performed with Microsoft® Excel 2016® for MacOS®. Results: The average age was 3,96 ± 3,24 years. The statistical fashion was 2 years. All patients underwent a upper gastrointestinal endoscopy. The most frequent FB was the coin (61,9%). In 6 opportunities (14,2%) was a button batery. FB retention was in the proximal third of the esophagus (30,9%), the gastric body (26,2%) and the distal third of the esophagus (14,2%), being extracted mainly with foreign body clamp (90,4%). The 57,5% showed some injury related to the location of the FB, being the most serious the produced by button batery. Conclusion: FBI in children is a potentially dangerous entity, so it becomes necessary to have a pediatric endoscopy unit and treatment protocols to avoid complications, especially with high-risk objects.

Caustic ingestion in children in south of Iran: Retrospective study from Shiraz - Iran / Ingestión de cáusticos en niños del sur de Irán: Estudio retrospectivo de Shiraz - Irán

Caustic ingestion is a major health concern in both developed and developing countries, that may lead to serious esophageal injury. The clinical presentation of caustic ingestion in children vary from asymptomatic to serious and fatal sequelae, such as perforation and stricture formation. Objective: Due to the lack of a comprehensive study in our area, this study has evaluated clinical and endoscopic manifestations and complications of caustic ingestion in children in south of Iran. Materials and methods: In this retrospective study, we reviewed 75 children with caustic ingestion who admitted in Nemazee Hospital of Shiraz University of Medical Science during 6 years (2006-2011). Sign and symptoms were recorded for each case. Results: The most common symptoms were dysphagia, oral lesions, vomiting, and drooling. Esophageal injuries were detected in both acid and alkali ingestion, but gastric injuries was significantly more in acid ingestion. During follow up period, 20% of all cases developed esophageal stricture. Conclusion: Dysphagia, oral lesions, vomiting, and drooling were the most common findings. Esophageal stricture was found in 20% of cases during 3 months of follow up.

La ingestión de cáusticos es una gran preocupación de salud tanto en países desarrollados como en vías de desarrollo, que puede llevar a lesiones esofágicas graves. La presentación clínica de la ingestión de cáusticos en niños varía desde asintomática hasta tener secuelas fatales, como perforación y/o estenosis. Objetivo: Debido a la ausencia de estudios en nuestra área, este estudio ha evaluado las manifestaciones clínicas, endoscópicas y las complicaciones de la ingesta de cáusticos en niños en el sur de Irán. Materiales y métodos: En estudio retrospectivo, revisamos 75 niños con ingesta de cáusticos que ingresaron al Nemazee Hospital of Shiraz University of Medical Science durante 6 años (2006-2011). Los signos y síntomas fueron recolectados para cada caso. Resultados: Los síntomas más frecuentes fueron disfagia, lesiones orales, vómitos y salivación. Las lesiones esofágicas se detectaron tanto en ingestión de ácido como de álcali, pero las lesiones gástricas fueron definitivamente más frecuentes con la ingestión de ácidos. Durante el periodo de seguimiento el 20% de los casos desarrolló estrechez esofágica. Conclusión: La disfagia, lesiones orales, vómitos y salivación fueron los hallazgos más comunes. La estrechez esofágica se encontró en el 20% de los casos durante los tres meses de seguimiento de los pacientes.

Inusual hallazgo de dos monedas juntas en esófago de pacientes pediátricos: Reporte de dos casos / An unusual finding of two coins together in the esophagus of pediatric patients: Report of two cases

La ingestión de cuerpos extraños (CE) es un motivo de consulta frecuente en los Servicios de Urgencia Pediátricos. Los estudios reportan que en la edad pediátrica se presenta el 80% de los CE, siendo más frecuente entre los 6 meses y los 3 años de edad, constituyendo la segunda causa de endoscopía digestiva urgente en pediatría. En 80 a 90% de los casos el CE pasa espontáneamente a través del tracto gastrointestinal superior; sin embargo, en ocasiones se aloja en el esófago y debe ser extraído para evitar complicaciones peligrosas como obstrucción o perforación del tracto digestivo superior, sangrado, úlceras, o fístulas. La ingesta e impactación de cuerpos extraños múltiples en el esófago, es un evento muy pocas veces reportado en población infantil. La mayoría de reportes, corresponde a la ingesta de magnetos, que aunque siendo aún de presentación infrecuente, pueden causar serias complicaciones gastrointestinales debido a que la atracción entre ellos puede atrapar las paredes de múltiples asas intestinales provocando perforación, formación de fistulas, vólvulos, hemorragia intraperitoneal e incluso la muerte. Aunque las monedas son los cuerpos extraños más comúnmente encontrados en esófago en niños, el hallazgo de múltiples monedas es en evento muy pocas veces reportado. Se presentan dos casos de pacientes pediátricos atendidos en el servicio de emergencia, con el hallazgo de dos monedas juntas y alineadas a nivel esofágico.

The ingestion of foreign bodies (EB) is a frequent complaint in the Pediatric Emergency Services. Studies report that in children occurs 80% of the EC, most frequently between 6 months and 3 years old and the second held because of urgent endoscopy in pediatrics. In 80-90% of cases the CE spontaneously passes through the upper gastrointestinal tract, however occasionally staying in the esophagus and should be removed to avoid dangerous complications such as obstruction or perforation of the upper digestive tract bleeding, ulcers, or fistulas. Intake and impaction of multiple foreign bodies in the esophagus, is a few event times reported in children. Most reports, corresponds to the ingestion of magnets, although still rare even presentation, can cause serious gastrointestinal complications, because the attraction between them can trap walls causing multiple small bowel perforation, fistula formation, volvulus, intraperitoneal hemorrhage and even death. Although the coins are the most commonly found foreign bodies in esophagus in children, the discovery of multiple currencies is very few times reported event. Two cases of pediatric patients treated in the emergency, with the discovery of two coins together and aligned with esophageal level is presented.

Esophageal Hemangioma Treated by Endoscopic Mucosal Resection: A Case Report and Review of the Literature / 대한소화기학회지

Hemangioma of the esophagus is a rare form of benign esophageal tumor. It usually presents as a single lesion located in the lower third of the esophagus and is mostly asymptomatic. However, it may occasionally cause hematemesis and/or obstruction. Surgical resection is the conventional treatment modality for managing esophageal hemangioma, but less invasive approaches such as endoscopic therapy are recently becoming more widely employed. Herein, we report a case of a 54-year-old man who presented with an esophageal hemangioma that was successfully treated by endoscopic mucosal resection without any complications.

Critérios morfológicos no esôfago de Barrett / Morphological criteria in Barrett's esophagus

Define-se esôfago de Barrett (EB) quando há a substituição do epitélio escamoso estratificado na porção distal do esôfago por epitélio do tipo colunar metaplásico com predisposição ao desenvolvimento de câncer. O desenvolvimento de metaplasia no EB parece ser uma adaptação da mucosa à inflamação crônica do tecido causada pelo pH ácido no refluxo gastresofágico crônico, visto que o novo epitélio apresenta uma maior resistência ao refluxo. O esôfago de Barrett nos países ocidentais é identificado a partir de análise endoscópica e posterior confirmação histológica. Além disso, deve-se também avaliar a presença de células displásicas ou neoplásicas. Nesse trabalho realizou-se uma revisão e análise da literatura publicada entre os anos de 2003 a 2012 e alguns artigos denominados clássicos sobre o assunto. Este estudo teve como objetivo uma revisão atualizada sobre o tema com foco nos critérios morfológicos do esôfago de Barrett, metaplasia, displasia e adenocarcinoma esofágico (ACE), além de uma breve discussão sobre sua patogenia. Há controvérsia na literatura acerca da adoção das células caliciformes como tipo celular característico no EB e da relação entre metaplasia intestinal e desenvolvimento de ACE. Como não há um consenso sobre esse assunto, parece apropriado não estender o conceito de EB enquanto não se obtém dados que comprovem um risco aumentado de ACE nesses tipos celulares.

Acalasia en paciente pediátrico: reporte de caso clínico y revisión de la literatura / Achalasia in a pediatric patient: case report and literature review

Achalasia is a rare disease in children. It is an idiopathic disease characterized by loss of normal peristalsis in the distal esophagus and the inability of the lower esophageal sphincter (LES) to relax properly. It presents with dysphagia and weight loss. The imaging study, particularly the study of the esophagus, stomach, duodenum with barium contrast medium, is the diagnostic test of choice, which in 95% of cases enables a diagnosis. There are various therapeutic options including pneumatic dilation (PD), botulinum toxin injection (BT) and surgery, with the latter giving the best long-term results, the access path is mainly laparoscopic. We report the case of a pediatric patient, evaluated in our department, diagnosed with achalasia.

La acalasia es una enfermedad infrecuente en población pediátrica. Es una enfermedad de causa desconocida que se caracteriza por la pérdida de la peristalsis normal del esófago distal y de la incapacidad del esfínter esofágico inferior de relajarse adecuadamente. El estudio con imágenes, particularmente el estudio del esófago, estómago, duodeno con medio de contraste baritado, es el test de elección, el cual en un 95% de los casos nos otorga un diagnóstico de certeza. Existen diversas opciones terapéuticas, entre ellas la dilatación neumática, la toxina botulínica y la cirugía, siendo esta última la con mejores resultados a largo plazo, la vía de acceso es principalmente laparoscópica. Presentamos el caso de un paciente pediátrico, evaluado en nuestro departamento, diagnosticado de acalasia.

Esophageal Sinus Formation due to Cyanoacrylate Injection for Esophageal Variceal Ligation-induced Ulcer Bleeding in a Cirrhotic Patient / 대한소화기학회지

Intravariceal injection of N-butyl-2-cyanoacrylate is widely used for the hemostasis of bleeding gastric varices, but not routinely for esophageal variceal hemorrhage because of various complications such as pyrexia, bacteremia, deep ulceration, and pulmonary embolization. We report a rare case of esophageal sinus formation after cyanoacrylate obliteration therapy for uncontrolled bleeding from post-endoscopic variceal ligation (EVL) ulcer. A 50-year-old man with alcoholic liver cirrhosis presented with hematemesis. Emergent esophagogastroscopy revealed bleeding from large esophageal varices with ruptured erosion, and bleeding was initially controlled by EVL, but rebleeding from the post-EVL ulcer occurred at 17th day later. Although we tried again EVL and the injections of 5% ethanolamine oleate at paraesophageal varices, bleeding was not controlled. Therefore, we administered 1 mL cyanoacrylate diluted with lipiodol and bleeding was controlled. Three months after the endoscopic therapy, follow-up endoscopy showed medium to large-sized esophageal varices and sinus at lower esophagus. Barium esophagography revealed an outpouching in esophageal wall and endoscopic ultrasonography demonstrated an ostium with sinus. It is noteworthy that esophageal sinus can be developed as a rare late complication of endoscopic cyanoacrylate obliteration therapy.

Balloon Dilatation for Corrosive Esophageal Strictures in Children: Radiologic and Clinical Outcomes

OBJECTIVE: We retrospectively evaluated the effectiveness of the esophageal balloon dilatation (EBD) in children with a corrosive esophageal stricture. MATERIALS AND METHODS: The study subjects included 14 patients (M:F = 8:6, age range: 17-85 months) who underwent an EBD due to a corrosive esophageal stricture. The causative agents for the condition were glacial acetic acid (n = 9) and lye (n = 5). RESULTS: A total of 52 EBD sessions were performed in 14 patients (range 1-8 sessions). During the mean 15-month follow-up period (range 1-79 months), 12 patients (86%) underwent additional EBD due to recurrent esophageal stricture. Dysphagia improved after each EBD session and oral feeding was possible between EBD sessions. Long-term success (defined as dysphagia relief for at least 12 months after the last EBD) was achieved in two patients (14%). Temporary success of EBD (defined as dysphagia relief for at least one month after the EBD session) was achieved in 17 out of 52 sessions (33%). A submucosal tear of the esophagus was observed in two (4%) sessions of EBD. CONCLUSION: Only a limited number of children with corrosive esophageal strictures were considered cured by EBD. However, the outcome of repeated EBD was sufficient to allow the children to eat per os prior to surgical management.

Schatzki's ring. an unusual clinical and radiological presentation

Schatzkis ring is a lower esophageal mucosal ring associated with a small sliding hiatus hernia. Most investigators described it as either an asymptomatic or symptomatic entity with chronic recurrent presentation of dysphagia. Barium swallow study in patients with Schatzkis ring was described as a thin smooth circumferential constriction at the GE junction. This case report describes an unusual clinical and radiological presentation in a patient with Schatzkis ring. Our adult male patient experienced sudden dysphagia, followed by spontaneous relief after an interval of 12 hours without specific treatment. Radiological findings were highly suggestive of lower esophageal malignancy. However, this possibility could be excluded by upper endoscopy and histopathological examination of biopsies taken from the lesion. The condition was diagnosed as Schatzkis ring with unusual clinical and radiological presentation

Clinical Significance of Incidentally Detected Bowel Wall Thickening on Abdominal Computerized Tomography Scan / 대한소화기학회지

BACKGROUND/AIMS: Due to widespread use of computerized tomography (CT) scan to examine patients with variable disease or complaints, detection of incidental or unsuspected gastrointestinal abnormalities are not uncommon. Clinical significance of incidentally detected bowel wall thickening (BWT) on abdominal CT scan is uncertain at present. Despite the necessity for the clinical guidelines describing the evaluation of incidental bowel wall thickening on CT scan, there have been few studies concerning these radiological abnormalities. Our objective was to determine whether endoscopic evaluation is necessary for the evaluation of these abnormal findings. METHODS: This study evaluated one hundred and forty patients with incidentally detected BWT on abdominal CT scan in Inje University Sanggye Paik Hospital from 2001 to 2003. 102 patients of those were proceeded by endoscopic evaluation. Forty-eight patients had received upper endoscopy, 26 patients had colonoscopy, while 28 patients had sigmoidoscopy. RESULTS: Endoscopic work up revealed significant abnormalities in 83% of patients with incidental findings of the distal esophagus, 73% of patients with thickening of the stomach, 35% of patients with thickening of the right colon, and 71% of patients with thickening of the sigmoid colon and rectum. CONCLUSIONS: Although significant pathologic findings are less common in thickening of the right colon than other bowel wall thickening, all of these incidental findings on CT scan warrant further endoscopic evaluation.

Imaging Findings of Giant Liposarcoma of the Esophagus

A giant esophageal liposarcoma showing rapid growth over 7 months is presented in 56-year-old man. It originated from the pharyngo-esophageal junction with a short stalk, and extended downward to the distal esophagus. A barium swallow study showed a large, sausage-like intraluminal mass in the dilated esophagus. CT and MR imaging showed a heterogeneous mass with a fatty component in the esophagus. A total laryngopharyngo-esophagectomy was performed and the histological diagnosis was of a well-differentiated liposarcoma.
