ABSTRACT

La hemorragia del tracto digestivo superior (HTDS) es el sangrado originado por encima del ángulo de Treitz. A pesar del aumento en las estrategias de prevención, del incremento en los tratamientos con Inhibidor de bomba de protones (IBP) y de la intervención endoscópica temprana, esta patología sigue siendo una causa frecuente de consulta a urgencias, con una morbimortalidad no despreciable y alta carga para el sistema de salud. Esta revisión se enfoca en la HTDS de causa diferente a las varices. La principal causante de esta entidad es la enfermedad ácido-péptica, que es consecuencia del gran consumo de antiinflamatorios no esteroideos (AINES) y de la infección por Helicobacter Pylori. Otras causas son el síndrome de Mallory Weiss, la esofagitis erosiva, las malformaciones arteriovenosas y la malignidad.


Upper gastrointestinal bleeding (UGIB) refers to any bleeding originating above the angle of Treitz. Despite an increase in prevention strategies, proton pump inhibitor (PPI) therapy and early endoscopic intervention, this pathology continues to be an important cause of admission to the emergency department for gastrointestinal causes, having a pretty high morbidity and mortality in addition to a high burden on the health system. This review focuses on non-variceal UGIB. The main cause of this entity being peptic acid disease, due to great consumption of NSAIDs and Helicobacter Pylori infection. Other causes are Mallory Weiss syndrome, erosive esophagitis, arteriovenous malformations, and malignancy.


A hemorragia do trato digestivo superior (HTDS) é o sangrado originado acima do ângulo de Treitz. Apesar do aumento nas estratégias de prevenção, do incremento nos tratamentos com Inibidor da bomba de prótons (IBP) e da intervenção endoscópica precoce, esta patologia segue sendo uma causa frequente de consulta a urgências, com uma morbimortalidade não depreciável e alta carga para o sistema de saúde. Esta revisão se enfoca na HTDS de causa diferente às varizes. A principal causante desta entidade é a doença ácido-péptica, que é consequência do grande consumo de anti-inflamatórios não esteróideos (AINES) e da infecção por HelicobacterPylori. Outras causas são a síndrome de Mallory Weiss, a esofagites erosiva, as malformações arteriovenosas e a malignidade. Palavras-chave: hemorragia gastrointestinal; úlcera péptica; endoscopia gastrointestinal; inibidores da bomba de prótons; medicina geral.

ABSTRACT

ABSTRACT BACKGROUND: The COVID-19 pandemic has changed digestive endoscopy services around the world. OBJECTIVE: This study aimed to measure the number of urgent/emergency endoscopic procedures performed in a Brazilian hospital, comparing it to the same period in the previous year, and to identify risk factors in COVID-19 patients undergoing endoscopic procedures for upper gastrointestinal bleeding (UGIB). METHODS: This was a retrospective, cross-sectional, observational, single-center study. The study evaluated urgent/emergency endoscopic procedures performed on adult patients from March to August in 2019 and 2020. The COVID-19 patients included were diagnosed using RT-PCR, aged over 18 years with complete medical record information. The variables evaluated were age, sex, comorbidities, length of stay, D-dimer, need for intensive care unit (ICU) and mechanical ventilation. Student's t-test for independent samples or the non-parametric Mann-Whitney test was used to compare quantitative variables. Categorical variables were analyzed using Fisher's exact test. A P-value <0.05 indicated statistical significance. RESULTS: A total of 130 urgent/emergency endoscopic procedures were performed in 2020 and 97 in 2019. During the study period, 631 patients were hospitalized due to COVID-19, of whom 16 underwent urgent/emergency endoscopic procedures, 10 (1.6%) due to UGIB. Of the variables analyzed, the need for ICU and/or mechanical ventilation during hospitalization was statistically significant as a risk factor for UGIB. CONCLUSION: This study showed increased urgent/emergency endoscopic procedures during the pandemic at the study site. Among the patients hospitalized with the novel coronavirus, there is a higher risk for UGIB in those needing ICU and/or mechanical ventilation.


RESUMO CONTEXTO: A pandemia da COVID-19 tem alterado o funcionamento de serviços de endoscopia digestiva pelo mundo. OBJETIVO: O presente estudo tem por objetivo medir o número de exames endoscópicos de urgência/emergência realizados em um hospital público brasileiro, comparando-o ao mesmo período do ano anterior, além de avaliar os fatores de risco dos pacientes com COVID-19 que realizaram exame endoscópico por hemorragia digestiva alta (HDA). MÉTODOS: Estudo retrospectivo, transversal, observacional e unicêntrico. Foram avaliados todos os exames endoscópicos de urgência/emergência realizados em pacientes acima de 18 anos, nos períodos de março a agosto dos anos de 2019 e 2020. Os pacientes com COVID-19 incluídos foram diagnosticados por RT-PCR, acima de 18 anos, com informações completas em prontuário. As variáveis avaliadas foram: tipo de exame endoscópico, idade, sexo, comorbidades, tempo de internação, d-dímero, necessidade de UTI e ventilação mecânica durante a internação. A comparação dos grupos em relação a variáveis quantitativas foi feita através do teste t de Student para amostras independentes ou o teste não-paramétrico de Mann-Whitney. As variáveis categóricas foram avaliadas pelo teste exato de Fisher. Valores de P<0,05 indicaram significância estatística. RESULTADOS: Observaram-se 130 exames endoscópicos de urgência/emergência no período avaliado em 2020, e 97 em 2019. No período do estudo foram internados 631 pacientes por COVID-19, dos quais 16 realizaram exame endoscópico de urgência/emergência, sendo 1,6% por HDA. Dentre as variáveis analisadas, necessidade de UTI e/ou ventilação mecânica durante o internamento foram estatisticamente significativos como risco para desenvolvimento de HDA. CONCLUSÃO: O presente estudo mostra que para a realidade local houve incremento de exames endoscópicos de urgência/emergência durante a pandemia. Dentre os pacientes internados com o novo coronavírus, há maior risco de HDA naqueles que necessitam de UTI e/ou ventilação mecânica.

ABSTRACT

ABSTRACT BACKGROUND: Ileitis is defined as ileal inflammation, with several etiologies, including inflammatory bowel disease (IBD), and can be evaluated during the colonoscopy exam, but its mandatory evaluation is discussed, because of few diagnosis and procedure time. OBJECTIVE: This study aims to evaluate the correlation of colonoscopic ileitis with the clinical presentation, in order to identify the cases where ileal examination is mandatory. METHODS: A retrospective, cross-sectional study was conducted between 2013 and 2017. The examination report, indications for colonoscopy, and medical records were evaluated in order to identify whether the colonoscopic findings were clinically significant. Patients over 18 years of age who had undergone ileoscopy were included, whereas patients below 18 years of age, those with previous intestinal resections, and repeated examinations of the same patient in the study period were excluded. The estimated association measure was the odds ratio with 95% confidence intervals. P-values <0.05 indicated statistical significance. RESULTS: A total of 3382 cases were included. Among these participants, 64.5% were females and the average age was 56.9±13.1 years (18-89 years). Ileal alterations were observed in 5.3% of the patients, with 2.69% being clinically significant between all patients, and 0.96% excluding those with IBD. There was a positive correlation between the ileitis findings and IBD control examinations and a negative correlation in screening and change in bowel habit indications. Among the indications with ileitis clinically significant, IBD control still had a positive correlation, 'diarrhea' and 'others' did not show a statistical significance, and all other indications presented a negative correlation for ileal assessment. CONCLUSION: Ileal evaluation in only mandatory in IBD control. When the main colonoscopy objective is detecting colonic neoplasms, ileoscopy is unnecessary.


RESUMO CONTEXTO: Ileíte é definida como inflamação ileal, com diversas etiologias, incluindo doença inflamatória intestinal (DII), e pode ser avaliada durante o exame de colonoscopia, mas sua avaliação obrigatória é discutida, devido aos poucos diagnósticos e tempo de procedimento. OBJETIVO: O objetivo deste estudo é avaliar a correlação da ileíte colonoscópica com a apresentação clínica, a fim de identificar os casos em que o exame ileal é obrigatório. MÉTODOS: Foi realizado um estudo transversal retrospectivo entre 2013 e 2017. O laudo do exame, as indicações para colonoscopia e os prontuários médicos foram avaliados para identificar se os achados colonoscópicos eram clinicamente significativos. Pacientes maiores de 18 anos submetidos à ileoscopia foram incluídos, enquanto pacientes menores de 18 anos, aqueles com ressecções intestinais prévias e exames repetidos do mesmo paciente no período de estudo foram excluídos. A medida de associação estimada foi o odds ratio com intervalos de confiança de 95%. Valores de P <0,05 indicaram significância estatística. RESULTADOS: Foram incluídos 3382 casos. Desses, 64,5% eram mulheres e a média de idade foi de 56,9±13,1 anos (18-89 anos). Alterações ileais foram observadas em 5,3% dos pacientes, sendo 2,69% clinicamente significativos entre todos os pacientes e 0,96% excluindo aqueles com DII. Houve uma correlação positiva entre os achados de ileíte e exames de controle de DII e uma correlação negativa no rastreamento e alteração de hábito intestinal. Entre as indicações com ileíte clinicamente significativa, o controle de DII ainda teve uma correlação positiva, 'diarreia' e 'outros' não apresentaram significância estatística, e todas as outras indicações apresentaram correlação negativa para avaliação ileal. CONCLUSÃO: A avaliação ileal é obrigatória apenas no controle de DII. Quando o objetivo principal da colonoscopia é detectar neoplasias colônicas, a ileoscopia é desnecessária.

ABSTRACT

La enfermedad de injerto contra huésped es una complicación grave que se presenta después del trasplante de médula ósea, con morbilidad y mortalidad elevadas. El patrón de oro para evaluar su compromiso gastrointestinal es la endoscopia digestiva alta y baja con toma de biopsia. El desarrollo de hematoma duodenal intramural es una complicación poco frecuente asociada con este procedimiento .Se presentan dos casos de hematoma duodenal intramural posendoscopia en pacientes con trasplante y sospecha de enfermedad injerto contra huésped que presentaron un cuadro agudo de dolor abdominal y sangrado intestinal. El diagnóstico se realizó por tomografía y recibieron tratamiento conservador, con un resultado favorable. En ambos casos, el diagnóstico de enfermedad injerto contra huésped gastrointestinal se hizo a través de las biopsias colónicas con histología duodenal normal, lo que sugiere evitar la toma de muestras duodenales para prevenir esta grave complicación en pacientes de alto riesgo y, de este modo, disminuir la morbilidad.


Graft versus host disease is a serious complication that occurs following bone marrow transplant with significant morbidity and mortality. The gold standard to diagnose gastrointestinal graft versus host disease is upper and lower gastrointestinal endoscopy with histological validation. The development of intramural duodenal hematoma is a rare complication associated with this procedure. We present two cases of intramural duodenal haematoma after duodenal biopsies in bone marrow transplant patients that presented clinically with severe abdominal pain and intestinal bleeding. In both cases, CT scans confirmed the diagnosis and they were treated conservatively with favorable outcomes.Final diagnosis of gastrointestinal graft versus host disease was based on the colonic samples with normal duodenal histoarchitecture, which could lead to avoiding duodenal samples in future patients in order to prevent this serious complication and thus diminish morbidity.

ABSTRACT

La litiasis vesicular sintomática puede presentarse asociada a litiasis de la vía biliar principal, siendo necesaria la utilización de medios diagnósticos adecuados para su posterior tratamiento. En este trabajo, se sugiere la evaluación mediante las guías de la Sociedad Americana para Endoscopia Gastrointestinal (American Society for Gastrointestinal Endoscopy ASGE), usando factores como la edad, pruebas hepáticas y hallazgos ecográficos, categorizando a los pacientes en baja, intermedia y alta probabilidad de coledocolitiasis. Estudio de diseño retrospectivo, observacional, descriptivo, de corte transversal, con un muestreo no probabilístico de casos consecutivos, sobre pacientes con diagnóstico de litiasis vesicular sintomática y sospecha de litiasis de la via biliar principal internados en la II Cátedra de Clínica Quirúrgica, del Hospital de Clínicas de San Lorenzo, entre los años 2017 a 2019. Con los siguientes resultados, de un total de 339 pacientes con diagnóstico de litiasis vesicular sintomática, el 6,64% tuvo el diagnóstico de coledocolitiasis asociada. En cuanto a los predictores muy fuertes de coledocolitiasis el más frecuentemente (68,6%,) encontrado fue el nivel de la bilirrubina total ≥ 4mg/dl; de los predictores fuertes el 70,6% presentaba la vía biliar principal dilatada; de los predictores moderados, el 84,3% presentó las enzimas hepáticas alteradas. En conclusión, se pudo identificar que la mayoría de los pacientes presentó alta probabilidad de coledocolitiasis y la conducta tomada fue realizar en primer lugar una colangiografía retrógrada endoscópica, con fines terapéuticos y luego colecistectomía, correspondiente al manejo correcto establecido por las guías actuales internacionales.


Symptomatic gallstones can occur associated with lithiasis of the main bile duct, requiring the use of adequate diagnostic tools for subsequent treatment. In this paper, we suggest using the guidelines of the American Society for Gastrointestinal Endoscopy (ASGE), that uses factors such as age, liver tests, and ultrasound findings, categorizing patients as those with low, intermediate, and high probability. of choledocholithiasis. A Retrospective, observational, descriptive, cross-sectional design study, with a non-probabilistic sampling of consecutive cases, on patients with a diagnosis of symptomatic gallstones and suspected stones of the main bile duct admitted to the the 2nd Surgical Department and Service of Clinica´s Hospital of San Lorenzo, between the years 2017 to 2019. With the following results; of a total of 339 patients with the diagnosis of symptomatic gallstones, 6.64% had associated choledocholithiasis. Regarding the very strong predictors of choledocholithiasis, the most frequent (68.6%) was the total bilirubin level ≥ 4mg / dl; 70.6% had a dilated main bile duct as a strong predictor; as a moderate predictor, 84.3% had altered liver enzymes. In conclusion, it was possible to identify that most of the patients presented a high probability of choledocholithiasis and the action taken was to first perform an endoscopic retrograde cholangiography, for therapeutic purposes, and then cholecystectomy, corresponding to the correct management established by current international guidelines.

ABSTRACT

Resumen Los parámetros de calidad para endoscopia digestiva alta han introducido indicadores intraprocedimiento, dentro de los cuales la adecuada visibilidad de la mucosa, libre de saliva, moco o burbujas, puede aumentar la posibilidad de detección de lesiones en fase temprana. Sin embargo, el uso de mucolíticos y antiburbujas ha mostrado gran variabilidad de eficiencia según las soluciones, concentraciones, tiempos de exposición y escala de visibilidad aplicados. Objetivos: determinar la efectividad de diferentes soluciones de premedicación para la limpieza de la mucosa digestiva; validar, mediante una prueba de concordancia interobservador, una nueva escala de adecuada visualización de la mucosa (TVMS) para el esófago, estómago y duodeno; y reportar eventos adversos o complicaciones relacionadas con las soluciones utilizadas y los procedimientos realizados. Material y métodos: estudio de cohortes prospectivas comparativas. Se incluyeron 412 pacientes adultos, ASA I y ASA II, para endoscopia diagnóstica bajo sedación consciente, distribuidos en 6 cohortes similares, divididas en dos grupos: no premedicación, 2 cohortes C1 (ayuno de 6 a 8 horas)y C2 (agua 100 mL); premedicación, 4 cohortes C3 a C6 (C3: agua 100 m L + simeticona 1000 mg; C4: agua 100 mL + simeticona 200 mg + N-acetilcisteína 600 mg; C5: agua 100 mL + simeticona 200 mg + N-acetilcisteína 1000 mg; C6: agua 100 mL + simeticona 200 mg + Hedera helix 70 mg). Se ingirió la solución 15 a 30 minutos antes del paso por cricofaríngeo. Se realizó la prueba de Kappa para medir la concordancia interobservador de la escala TVMS. Resultados: De 412 pacientes, 58% fueron de sexo femenino; 23% (136) fue de cohortes C1 y C2 y 67% (276) fue de cohortes C3 a C6. El tiempo medio de exposición a cada solución fue de 24,4 minutos. El volumen de lavado para lograr una adecuada visualización fue significativamente diferente entre ambos grupos: en los pacientes con premedicación se utilizaron 75,6 mL, mientras que en los pacientes sin premedicación se utilizaron 124 mL (p = 0,000), con una calidad de TVMS excelente de 88,7% frente al 41,4%, respectivamente. La cohorte C4 (agua 100 mL + simeticona 200 mg + N-acetilcisteína 600 mg) mostró ser la más efectiva con una diferencia significativa (p = 0,001) frente a C1 (ayuno) y C2 (placebo con agua 100 mL), y también tuvo una eficiencia superior frente a C3, C5 y C6 en su orden. No se presentaron eventos adversos o complicaciones en relación con la endoscopia, la sedación y los productos usados en la premedicación. Conclusiones: la solución más efectiva como premedicación para lograr una excelente visibilidad de la mucosa digestiva correspondió a la cohorte C4 (SIM 200 + NAC 600 + H2O 100 mL). La escala TVMS propuesta es una herramienta muy completa y fácil de aplicar por más de un observador. La premedicación ingerida, con antiburbuja, mucolítico y agua hasta 100 mL, entre 15 y 30 minutos previos a endoscopia, es segura en las condiciones descritas en este estudio.


Abstract Quality parameters for upper gastrointestinal endoscopy have introduced intraprocedural indicators, including adequate mucosal visualization free of saliva, mucus, or bubbles, which may increase the possibility of early-stage injury detection. The use of mucolytics and anti-foaming agents has shown great efficiency variability depending on the type of solution, concentrations, exposure times and visibility scale applied. Objectives: To determine the effectiveness of different premedication solutions for cleaning the digestive mucosa; to validate, by means of an interobserver concordance test, a new scale for the adequate visualization of the mucosa (TVMS) for the esophagus, stomach, and duodenum; and to report adverse events or complications associated with the solutions used and the procedures performed. Material and methods: Prospective, comparative cohort study. 412 adult patients, ASA I and ASA II, were included for diagnostic endoscopy under conscious sedation. They were distributed in 6 similar cohorts and divided into two groups: non-premedication, 2 in C1 (fasting 6 to 8 hours) and C2 (water 100 mL) cohorts; premedication, 4 C3 to C6 cohorts (C3: water 100 mL + simethicone 1000 mg; C4: water 100 ml + simethicone 200 mg + N-acetylcysteine 600 mg; C5: water 100 ml + simethicone 200 mg + N-acetylcysteine 1000 mg; C6: water 100 ml + simethicone 200 mg + Hedera helix 70 mg). The solution was swallowed 15 to 30 minutes passing through the cricopharyngeus muscle. The Kappa test was performed to measure interobserver concordance of the TVMS scale. Results: Of 412 patients, 58% were female; 23% (136) were included in the C1 and C2 cohorts; and 67% (276) were in the C3 to C6 cohorts. The average exposure time to each solution was 24.4 minutes. The wash volume for proper visualization was significantly different between the two groups. In premedicated patients, 75.6 mL of solution were used, while in patients without premedication, 124 mL were used (p = 0.000), with an excellent quality of TVMS of 88.7% versus 41.4%, respectively. The C4 cohort (water 100 mL + simethicone 200 mg + N-acetylcysteine 600 mg) was the most effective with a significant difference (p= 0.001) compared with the C1 (fasting) and C2 (placebo with water 100 mL) cohorts. It also had better efficiency compared to the C3, C5 and C6 cohorts in that order. There were no adverse events or complications associated with endoscopy, sedation, or premedication products. Conclusions: The most effective solution as a premedication to achieve excellent visibility of the digestive mucosa was that used in the C4 cohort (SIM 200 + NAC 600 + H2OR 100 mL). The proposed TVMS scale is a very complete and easy tool to apply by more than one observer. Premedication ingested, with anti-foam, mucolytic and water up to 100 mL, between 15 and 30 minutes before endoscopy, is safe under the conditions described in this study.

ABSTRACT

Resumen La ingesta de cuerpos extraños es una entidad clínica común en el servicio de gastroenterología; la mayoría de veces estos pasan a través del tracto digestivo de manera espontánea y, en algunos casos, pueden presentar complicaciones como obstrucción o perforación. Es importante realizar un diagnóstico temprano con el fin de definir una terapia conservadora o quirúrgica inmediata. Se presenta el caso de una paciente de 67 años de edad que ingresó al servicio de urgencias por dolor abdominal de 16 días de evolución; como había sospecha de tumor gástrico sobreinfectado, se solicitó una endoscopia digestiva alta para la toma de biopsias, pero de forma sorpresiva se extrajo una espina de pescado de 3,5 cm sin complicaciones; posteriormente, se realizó el manejo del absceso gástrico con antibióticos por 14 días, con un buen desenlace clínico.


Abstract Foreign body ingestion is a common reason for consultation to the Gastroenterology Service. Most of these bodies pass through the digestive tract spontaneously and, in some cases, may cause complications such as obstruction or perforation. Early diagnosis is crucial to establish immediate conservative or surgical therapy. The following is the case of a 67-year-old patient admitted to the Emergency Department due to abdominal pain of 16 days of evolution. Since an over-infected gastric tumor was suspected, an upper gastrointestinal endoscopy was requested for biopsy. Strikingly, a 3.5cm fish bone was removed without complications. Gastric abscess was treated subsequently with antibiotics for 14 days, obtaining a good clinical outcome.

ABSTRACT

Resumen Introducción: en el estudio de la baja talla de origen digestivo en niños no hay un patrón de paraclínicos preestablecido; sin embargo, la endoscopia de vías digestivas puede ser una herramienta útil para tal fin. Objetivo: reportar una serie de casos de niños con diagnóstico de baja talla a quienes se les indicó una endoscopia de vías digestivas altas como parte de su estudio. Reporte de casos: se incluyeron 15 niños entre los 2 y 16 años de edad, 53,3% niñas, 26,7% desnutridos según el índice de masa corporal y la talla para la edad, 66,7% con baja talla grave y 33,3% con baja talla moderada. El 53,3% presentó dolor abdominal, el 46,7% no tuvo ganancia de peso, el 26,7% tuvo inapetencia y el 13,3% tuvo vómito, entre otros. Entre el 40,0% y el 93,4% presentaron macro- o microscópicamente esofagitis, gastritis y duodenitis. Los hallazgos microscópicos más importantes fueron duodenitis crónica con giardiasis, úlceras duodenales, hiperplasia nodular linfoide duodenal, Helicobacter pylori y duodenitis crónica eosinofílica. Conclusiones: a pesar de que la endoscopia de vías digestivas es un método poco utilizado y no bien descrito en el estudio de niños con baja talla, este reporte de casos describe organicidad en un 80,0% de los niños analizados.


Abstract Introduction: The study of short stature of digestive origin in children shows no pre-established laboratory patterns. However, endoscopy of the digestive tract may be a useful tool for this purpose. Objective: To report a series of cases of children with a diagnosis of short stature who underwent upper digestive tract endoscopy as part of their study. Case report: 15 children between the ages of 2 and 16 years were included; 53.3% were girls. 26.7% presented with malnutrition according to their body mass index and height-for-age, 66.7% had short stature, and 33.3% moderate short stature. Abdominal pain was reported in 53.3% of the cases, and no weight gain in 46.7%. Other symptoms were lack of appetite in 26.7%, vomiting in 13.3%, among others. Between 40% and 93.4% of the children presented macro and/or microscopic esophagitis, gastritis, and duodenitis. The most important microscopic findings were chronic duodenitis with giardiasis, duodenal ulcers, duodenal nodular lymphoid hyperplasia, Helicobacter pylori, and chronic eosinophilic duodenitis. Conclusions: Although endoscopy of the digestive tract is a method barely used and not well described in the study of children with short stature, this case report describes organicity in 80% of the children analyzed.

ABSTRACT

Antecedentes: La hemorragia gastrointestinal oculta representa aproximadamente del 5%-10% del total de las hemorragias digestivas. Descripción del caso clínico: Paciente femenina de 62 años, procedente de Santa Cruz de Yojoa, Cortés, sin comorbilidades, con episodios intermitentes de melena de un año de evolución; evaluada y manejada con hierro parenteral y transfusiones sanguíneas. Se le realizó protocolo diagnóstico, sin encontrar origen del sangrado. Fue sometida a laparoscopía diagnóstica en junio del 2019, realizándole apendicectomía, resección yeyunal, colecistectomía y ooforectomía; cursando asintomática luego de la cirugía. En diciembre, reinicia con melena, 3-4 episodios diarios, abundante cantidad (aproximadamente 300 ml). Evaluada nuevamente sin lograr identificar el origen del sangrado, por lo cual se realizó vídeo capsula endoscópica que reportó, restos hemáticos sin observar sitio de sangrado. Se llevó a cabo enteroscopía de empuje y duodenoscopía observando sitio de sangrado cercano a la papila duodenal. Se decide realizar angiotomografía, la cual fue compatible con sangrado digestivo a nivel de la II y III porción del duodeno. Luego se efectúa arteriografía selectiva de vasos abdominales, evidenciando fuga de medio de contraste originada en la rama de la arteria hepática derecha de origen en la mesentérica superior. Finalmente se procedió a la aplicación de 2 hemoclip vía endoscópica obteniendo un resultado satisfactorio.Conclusiones: El tipo de lesión responsable de la hemorragia del intestino delgado depende de la edad del paciente. Los factores de riesgo de hemorragia recurrente por angioectasia incluyen el número de lesiones, la edad avanzada, comorbilidades y la terapia anticoagulante...(AU)

ABSTRACT

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.

ABSTRACT

OBJECTIVES@#At present, there are many studies on Crohn's disease of terminal ileum and colon, but few studies on Crohn's disease of small intestine alone. This study aims to analyze the clinical features and therapeutic effect of small bowel in adult patients with Crohn's disease so as to strengthen the diagnosis and treatment for this disease.@*METHODS@#From July 1, 2015 to October 31, 2018, patients with small bowel Crohn's disease at Department of Gastroenterology, Third Xiangya Hospital of Central South University, were enrolled. At the same time, patients' demographics and clinical data were collected.@*RESULTS@#A total of 44 patients were small bowel Crohn's disease. Among them, 40 patients were male. The age at diagnosis was (35.8±10.3) years old and disease duration was (35.2±59.5) months. The subtypes included 29(65.9%) of ileum, 7(15.9%) of jejunum, 8(18.2%) of ileum with jejunum. There were 27(61.4%) of stricture behavior, 4(9.1%) of penetrating behavior, and 13(29.5%) of non-stricture and non-penetrating behavior. Endoscopic visible stricture (29/85, 34.1%) was common, followed by longitudinal ulcers (27/85, 31.8%). Non-caseate granulomatous were found in 2 cases (4.5%). The score of Crohn's disease activity index was correlated to hemoglobin, hematocrit, and erythrocyte sedimentation rate (all @*CONCLUSIONS@#Patients with ileum account for a large proportion in patients with small bowel Crohn's disease. Stricture is more common in small bowel Crohn's disease. Stricture and longitudinal ulcer are more common under enteroscopy. Crohn's disease activity index is correlated to hemoglobin, red blood cell specific volume, and erythrocyte sedimentation rate. The most common complication is intestinal obstruction. Mesalazine is less effective on small bowel Crohn's disease.

ABSTRACT

Based on the principle of magnetic anastomosis technique, the design of magnetic anastomosis system for endoscopic tissue clamping is proposed. The system includes a semi-ring magnet, a special structure transparent cap and a detachable push rod. With the help of the existing digestive endoscopy and endoscopic tissue gripper, the endoscopic close clamping and anastomosis of the bleeding or perforated tissue can be completed. After the anastomosis, the magnet falls off and is discharged through the digestive tract. Animal experiments showed that the system was easy to use, the fistula was clamped firmly, the magnet was discharged for 7~21 days, and there was no magnet retention and digestive tract obstruction. Further safety verification, optimization of endoscopic operation, the system can be used in clinical trial.

ABSTRACT

OBJECTIVES@#To study the risk factors for complications after endoscopic therapy for upper gastrointestinal subepithelial lesions (SELs).@*METHODS@#Retrospective analysis was performed on 184 patients in the Department of Gastroenterology in the Third Xiangya Hospital, Central South University after therapeutic endoscopy [endoscopic submucosal dissection (ESD), endoscopic full-thickness resection (EFR), endoscopic submucosal excavation (ESE), and submucosal tunneling endoscopic resection (STER)] for the upper gastrointestinal SELs from 2014-09-01 to 2019-09-30. The clinic data were collected and risk factors for postoperative complications were analyzed.@*RESULTS@#Among the 184 patients, 22 patients were in the complication group (including 3 cases of delayed bleeding, 2 cases of delayed perforation, and 17 cases of electrocoagulation syndrome) and 162 patients were in the non-complication group. There was no significant difference between the complication group and the non-complication group in gender, age over 70 year, basic diseases, lesion location, lesion invasion layers, pathological results, endoscopic therapy, and preventive closure of wounds (all @*CONCLUSIONS@#For the patients with upper gastrointestinal SELs after endoscopic minimally invasive therapy with the lesion diameter over 40 mm and the operative time over 120 minutes, it needs to highly alert to the occurrence of postoperative complications.

ABSTRACT

Resumen Introducción: Con la escala de Glasgow-Blatchford (EG-B) se califica mediante datos clínicos, el riesgo de resangrado después de hemorragia del tubo digestivo alto (HTDA); y con las escalas de Forrest y Dagradi, mediante endoscopia. Objetivo: Evaluar la capacidad de la EG-B para identificar riesgo de resangrado a 30 días después de una HTDA; el estándar de oro de comparación fue la endoscopia. Método: Se analizaron 129 expedientes de pacientes con HTDA y endoscopia. Se cuantificaron las escalas de Glasgow-Blatchford, Forrest y Dagradi; se calculó sensibilidad, especificidad y área bajo la curva ROC (ABC-ROC) del riesgo de resangrado reportado por EG-B. Resultados: La EG-B identificó a 53 pacientes con riesgo bajo de resangrado (41.09 %) y 76 con riesgo alto (58.91 %). Con la endoscopia se identificó a 107 pacientes con hemorragia no variceal (82.94 %), 98 con riesgo bajo (89.9 %) y 11 con riesgo alto (10.09 %); además, 22 pacientes con hemorragia variceal (17.05 %), 12 con riesgo bajo (54.54 %) y 10 con riesgo alto (45.45 %). La EG-B mostró sensibilidad de 0.857, especificidad de 0.462 y ABC-ROC de 0.660. Conclusiones: La EG-B es sencilla, objetiva y útil para identificar riesgo de resangrado después de HTDA; se sugiere como herramienta de triaje en urgencias.


Abstract Introduction: The Glasgow-Blatchford scale (GBS) classifies the risk of re-bleeding after upper gastrointestinal bleeding (UGIB) using clinical data, whereas the Forrest and Dagradi scales do it by endoscopy. Objective: To assess GBS’s ability to identify re-bleeding risk within 30 days of an UGIB, using endoscopy as the gold standard for comparison. Method: 129 medical records of patients with UGIB and endoscopy were analyzed. The Glasgow-Blatchford, Forrest and Dagradi scales were quantified; sensitivity, specificity and area under the ROC curve (AUC-ROC) of GBS-reported re-bleeding risk were calculated. Results: GBS identified 53 patients with low re-bleeding risk (41.09 %) and 76 with high risk (58.91 %). Endoscopy identified 107 patients with non-variceal bleeding (82.94 %): 98 with low risk (89.9 %) and 11 with high risk (10.09 %); in addition, it identified 22 patients with variceal hemorrhage (17.05 %): 12 with low risk (54.54 %) and 10 with high risk (45.45 %). GBS showed a sensitivity of 0.857, specificity of 0.462 and an AUC-ROC of 0.660. Conclusions: GBS is simple, objective and useful to identify the risk of re-bleeding after UGIB; it is suggested as a triage tool in the emergency department.

ABSTRACT

Abstract Background and objectives Day-case pediatric sedation is challenging. Dexmedetomidine is a sedative analgesic that does not induce respiratory depression. We compared dexmedetomidine to propofol when it was added to ketamine for sedation during pediatric endoscopy, regarding recovery time and hemodynamic changes. Methods We enrolled 120 patients (2−7 years in age) and randomly assigned them into two groups. Each patient received intravenous (IV) ketamine at a dose of 1 mg.kg-1 in addition to either propofol (1 mg.kg-1) or dexmedetomidine (0.5 µg.kg-1). The recovery time was compared. Hemodynamics, oxygen saturation, need for additional doses, postoperative complications and endoscopist satisfaction were monitored. Results There was no significant difference in hemodynamics between the groups. The Propofol-Ketamine (P-K) group showed significantly shorter recovery times than the Dexmedetomidine-Ketamine (D-K) group (21.25 and 29.75 minutes, respectively, p < 0.001). The P-K group showed more oxygen desaturation. Eleven and 6 patients experienced SpO2 < 92% in groups P-K and D-K, respectively. A significant difference was noted regarding the need for additional doses; 10% of patients in the D-K group needed one extra dose, and 5% needed two extra doses, compared to 25% and 20% in the P-K group, respectively (p = 0.001). The P-K group showed less post-procedure nausea and vomiting. No statistically significant difference between both groups regarding endoscopist satisfaction. Conclusions The P-K combination was associated with a shorter recovery time in pediatric upper gastrointestinal endoscopy, while the D-K combination showed less need for additional doses.

Resumo Justificativa e objetivos A sedação ambulatorial pediátrica é um desafio. A dexmedetomidina é um analgésico sedativo que não induz à depressão respiratória. Comparamos a dexmedetomidina ao propofol quando associados à cetamina para sedação durante endoscopia pediátrica, quanto ao tempo de recuperação e às alterações hemodinâmicas. Métodos Foram recrutados 120 pacientes (2−7 anos de idade) que foram aleatoriamente alocados em dois grupos. Cada paciente recebeu cetamina IV na dose de 1 mg.kg‐1, além de propofol (1 mg.kg‐1) ou dexmedetomidina (0,5 µg.kg‐1). Comparamos o tempo de recuperação. A hemodinâmica, saturação de oxigênio, necessidade de doses adicionais, complicações pós‐operatórias e satisfação do endoscopista foram monitoradas. Resultados Não houve diferença significante entre os grupos no que diz respeito à hemodinâmica. O grupo Propofol‐Cetamina (P‐C) apresentou tempos de recuperação significantemente mais curtos do que o grupo Dexmedetomidina‐Cetamina (D‐C) (21,25 e 29,75 minutos respectivamente, p < 0,001). Observou‐se frequência maior de dessaturação de oxigênio no grupo P‐C. Onze e 6 pacientes apresentaram SpO2 < 92% nos grupos P‐C e D‐C, respectivamente. Uma diferença significante foi observada em relação à necessidade de doses adicionais; 10% dos pacientes no grupo D‐C precisaram de uma dose extra e 5% precisaram de duas doses extras, em comparação com 25% e 20% no grupo P‐C, respectivamente (p = 0,001). O grupo P‐C apresentou menos náuseas e vômitos após o procedimento. Não houve diferença estatisticamente significante entre os dois grupos em relação à satisfação do endoscopista. Conclusões A combinação P‐C foi associada a tempo mais curto de recuperação na endoscopia digestiva alta pediátrica, enquanto a combinação D‐C mostrou menor necessidade de doses adicionais.

ABSTRACT

Introducción:Existen estudios que asocian a los grupos sanguíneos con el desarrollo de cáncer gástrico, estableciendo una relación entre los individuos con grupo sanguíneo A y la predisposición a esta neoplasia, sin embargo estos reportes podrían estar sesgados por la prevalencia poblacional del tipo sanguíneo de la región. El objetivo de este estudio es establecer la relación predicha en una zona de alta prevalencia de tipo sanguíneo O. Métodos: Este estudio observacional, analítico fue llevado a cabo en pacientes que se realizaron biopsia de estómago vía endoscópica atendidos en el Instituto de Cáncer SOLCA Cuenca en el período 2013 ­2018; el muestreo es no probabilístico de todos los casos posibles. Para el análisis se conforma el grupo 1 (G1) con pacientes con Biopsia Positiva para Cáncer Gástrico, el grupo 2 con pacientes con Biopsia negativa para Cáncer Gástrico. Se realiza análisis de asociación con Razón de Prevalencia (RP). Resultados: Fueron 433 casos de cáncer gástrico en G1y 2606 casos negativos para Cáncer Gástrico en G2. La prevalencia del tipo de sangre "O" en G1fue 328/433 casos (75.75%) Vs. 1946/2606 casos (74.67%); la prevalencia del tipo de sangre "A" en G1 fue 71/433 casos (16.4%) Vs 485/2606 casos (18.61%) en G2; RP=0.875 (IC95% 0.69 -1.11), P=0.27. Conclusiones: No se demostró asociación entre el tipo de sangre y la presencia de Cáncer Gástrico en el presente reporte.


Introduction:There are studies that associate blood groups with the development of gastric cancer, establishing a relationship between individuals with blood group A and a predisposition to this neoplasia, however these reports could be biased by the population prevalence of the blood type of the region. The objective of this study is to establish the predicted relationship in an area with a high prevalence of blood type O. Methods: This observational, analytical study was carried out in patients who underwent endoscopic stomach biopsy treated at the SOLCA Cuenca Cancer Institute in the period 2013 -2018; the sampling is non-probability of all possible cases. For the analysis, group 1 (G1) is made up of patients with a Positive Biopsy for Gastric Cancer, group 2 with patients with a negative Biopsy for Gastric Cancer. Association analysis with Prevalence Ratio (PR) is performed. Results: There were 433 cases of gastric cancer in G1 and 2606 negative cases for Gastric Cancer in G2. The prevalence of blood type "O" in G1 was 328/433 cases (75.75%) Vs. 1946/2606 cases (74.67%); the prevalence of blood type "A" in G1 was 71/433 cases (16.4%)Vs 485/2606 cases (18.61%) in G2; PR = 0.875 (95% CI 0.69 -1.11), P = 0.27. Conclusions: No association between blood type and the presence of Gastric Cancer was demonstrated in this repor
