RESUMO

Las várices gástricas (VG) son un complejo de colaterales vasculares entre la circulación portal y sistémica, condición que se desarrolla como resultado de la presión elevada en el sistema venoso portal. Se encuentran en el 20 % de los pacientes con cirrosis, y son menos frecuentes que las várices esofágicas. Según la clasificación de Sarin, las VG se dividen en cuatro tipos según su ubicación en el estómago y su relación con las várices esofágicas (GOV1, GOV2, IGV1 e IGV2). Entender su hemodinámica con respecto a las rutas de drenaje de las VG es importante para guiar su tratamiento.

Gastric varices (GV) are a complex of vascular collaterals between portal and systemic circulation, a condition that develops as a result of elevated pressure in the portal venous system. They are found in 20% of patients with cirrhosis, and are less common than esophageal varices. According to the Sarin classification, GV are divided into four types based on their location in the stomach and their relationship with esophageal varices (GOV1, GOV2, IGV1, and IGV2). Understanding their hemodynamics with respect to GV drainage routes is important to guide their treatment.

RESUMO

ABSTRACT Objective: To evaluate the efficacy of scheduled second-look endoscopy in patients with acute peptic ulcer bleeding (PUB). Materials and methods: We systematically search in four databases for randomized controlled trials (RCTs) that evaluated the usefulness of scheduled second-look endoscopy vs. single endoscopy in patients with PUB. Our primary outcome was rebleeding. Secondary outcomes were surgery, mortality, and the number of units of blood transfused (NUBT). All meta-analyses were performed using a randomeffects model. Pooled risk ratio (RR) and mean difference (MD), with their 95% confidence intervals (CIs) were calculated for categorical and continuous outcomes, respectively. The risk of bias was assessed using the Cochrane RoB 2.0 tool, and the quality of evidence (QoE) was rated with the GRADE approach. Results: Eight full-text RCTs and two RCT abstracts were included (n=1513). We did not find differences in rebleeding (RR, 0.78; 95% CI, 0.531.14, moderate QoE), surgery (RR, 0.58; 95% CI, 0.29-1.15, moderate QoE), mortality (RR, 0.89; 95% CI, 0.46-1.71, moderate QoE) or NUBT (MD, -0.01 units; 95% CI, -0.3 to 0.28, low QoE) between second-look and single endoscopy. Sensitivity analyses had similar results to the main analyses. Conclusions: Routine second-look endoscopy was not more efficacious than single endoscopy in patients with PUB.

RESUMEN Objetivo: Evaluar la eficacia de la endoscopia de revisión programada en pacientes con hemorragia por úlcera péptica aguda (UPA). Materiales y métodos: Buscamos de forma sistemática en cuatro bases de datos ensayos controlados aleatorios (ECA) que evaluaran la utilidad de la endoscopia de control programada versus la endoscopia única en pacientes con UPA. Nuestro outcome primario fue el resangrado. Los outcomes secundarios fueron la necesidad de cirugía, la mortalidad y el número de unidades de sangre transfundidas (NUST). Todos los meta-análisis se realizaron mediante un modelo de efectos aleatorios. Se calcularon el riesgo relativo (RR) combinado y la diferencia de medias (DM), con sus intervalos de confianza (IC) del 95% para los resultados categóricos y continuos, respectivamente. El riesgo de sesgo se evaluó mediante la herramienta Cochrane RoB 2.0 y la calidad de la evidencia (QoE) se calificó con el enfoque GRADE. Resultados: Se incluyeron ocho ECA de texto completo y dos resúmenes de ECA (n = 1513). No encontramos diferencias en resangrado (RR, 0,78; IC 95%, 0,53-1,14, QoE moderada), cirugía (RR, 0,58; IC 95%, 0,291,15, QoE moderada), mortalidad (RR, 0,89; 95% IC, 0,46-1,71, QoE moderada) o NUST (DM, -0,01 unidades; IC del 95%, -0,3 a 0,28, QoE baja) entre la segunda revisión y la endoscopia única. Los análisis de sensibilidad tuvieron resultados similares a los análisis principales. Conclusiones: La endoscopia de control de rutina no fue más eficaz que la endoscopia única en pacientes con UPA.

RESUMO

RESUMEN La enfermedad celiaca (EC) es un síndrome malabsortivo autoinmune que se presenta con intolerancia al gluten (gliadina). Los síntomas más frecuentes son diarrea, esteatorrea, pérdida de peso, debilidad, deficiencia de vitaminas y minerales. La probabilidad de desarrollar una EC complicada es relativamente baja, entre las principales manifestaciones de la misma tenemos esprue refractario, el linfoma de células T y la yeyunoileitis ulcerativa (YU) de los cuales pocos casos debutan con hemorragia digestiva. A continuación, presentamos el caso de un paciente de 51 años de edad que debutó con hemorragia digestiva debido a EC complicada, en donde se realizó video endoscopía digestiva alta (VEDA), videocolonoscopia (VCC), cápsula endoscópica (CE), enteroscopia y biopsia de yeyuno e íleon confirmando el diagnóstico de EC y yeyunoileitis ulcerativa.

ABSTRACT Celiac disease (CD) is an autoimmune malabsorption syndrome that presents with intolerance to gluten (gliadin), a protein found in wheat. The most common symptoms are diarrhea, steatorrhea, weight loss, weakness, vitamin and mineral deficiency. The probability of developing complicated CD is relatively low, among its main manifestations we have refractory sprue, T-cell lymphoma and ulcerative jejunitis (UY) of which a few cases develop gastrointestinal bleeding. Furthermore, we present the case of a 51-year-old patient who developed intestinal hemorrhage due to complicated CD, where upper digestive video endoscopy (VEDA), video colonoscopy (VCC), capsule endoscopy (CE) and biopsy of the jejunum and ileum were performed confirming the diagnosis of CD along with ulcerative jejunoileitis.

RESUMO

ABSTRACT Introduction: In 2020, the world suffered a major impact from the COVID-19 pandemic, especially due to the high transmissibility of the virus. It is a disease that predominates with respiratory manifestations, but there is involvement of the gastrointestinal tract, causing symptoms ranging from mild to more severe. Highlighting gastrointestinal bleeding, it is a symptom resulting from the involvement of the SARS-CoV-2 virus described by several reports and case series. Methods: through an integrative literature review, of a qualitative nature, works that corresponded to the eligibility criteria were selected, totaling 16 articles included in this review. Results: of the patients who manifested gastrointestinal symptoms associated with the disease, common comorbidities and clinical manifestations were identified, in addition to therapies used to treat the infection, which were predisposing factors for the development of gastrointestinal bleeding. Conclusion: The presence of gastrointestinal bleeding in patients with COVID-19 is established in the literature, since the pathophysiological mechanisms of the disease directly affect the GIT. Early recognition of symptoms and suspicion of gastrointestinal involvement allows better management of patients and complications.

Destacando o sangramento gastrointestinal, é um sintoma decorrente do acometimento do vírus SARS-CoV-2 descrito por diversos relatos e séries de casos. Métodos: por meio de uma revisão integrativa da literatura, de caráter qualitativo, foram selecionados trabalhos que correspondessem aos critérios de elegibilidade, totalizando 16 artigos incluídos nesta revisão. Resultados: dos pacientes que manifestaram sintomas gastrointestinais associados a doença, foram identificadas comorbidades e manifestações clínicas em comum, além de terapias utilizadas como tratamento da infecção, que foram fatores predisponentes para o desenvolvimento de sangramentos gastrointestinais. Conclusão: a presença de sangramento gastrointestinal em pacientes com COVID-19 é um dado firmado na literatura, uma vez que os mecanismos fisiopatológicos da doença afetam diretamente o TGI. O reconhecimento precoce dos sintomas e a suspeita do acometimento gastrointestinal permite um melhor manejo dos pacientes e das complicações.

RESUMO

La amiloidosis intestinal es una enfermedad sistémica rara y subdiagnosticada, la cual se caracteriza por el depósito extracelular de proteínas que se agrupan en fibras amiloides. Esta entidad es infrecuente y suele ser una forma de presentación en el contexto de una amiloidosis sistémica, cuyo diagnóstico se basa en la presencia a amiloide en la histología. La clínica suele ser inespecífica; diarrea crónica, pérdida de peso, dolor y distensión abdominal; siendo la hemorragia digestiva una manifestación muy poco frecuente. Se presenta el caso de una mujer de 61 años con clínica de baja de peso, distención abdominal, náuseas, vómitos y melena. En la tomografía se evidenció un engrosamiento mural de asas yeyunales con captación de contraste, hallazgo que se corroboró con enteroscopia anterógrada a doble balón en el cual se evidenciaron múltiples úlceras en yeyuno, signos de atrofia, friabilidad y dilatación de luz yeyunal. En la anatomía patológica se aprecia arquitectura vellositaria distorsionada y ulcerada con histoquímica positiva a Rojo Congo e inmunohistoquímica lambda (+++). Además, se realizó aspirado de médula ósea y biopsia de hueso compatible con infiltración de mieloma múltiple monoclonal a cadena Lambda. Durante la estancia hospitalaria la paciente cursó con complicaciones como la desnutrición crónica, infección recurrente y varios episodios de suboclusión intestinal; caracterizada por neumatosis intestinal; debido a múltiples episodios de estas complicaciones la paciente fallece. Dentro de la práctica clínica en gastroenterología la amiloidosis intestinal como parte del diagnóstico diferencial de la hemorragia digestiva alta es infrecuente, por lo que los antecedentes de diagnóstico de mieloma múltiple u otras gammapatías monoclonales asociadas a cadenas ligeras es crucial para un diagnóstico precoz y tratamiento adecuado.

Intestinal amyloidosis is a rare and underdiagnosed systemic disease, which is characterized by the extracellular deposition of proteins that are grouped into amyloid fibers. This entity is rare and is usually a form of presentation in the context of systemic amyloidosis, the diagnosis of which is based on the presence of amyloid in histology. The clinic is usually non-specific; chronic diarrhea, weight loss, abdominal pain and bloating; Gastrointestinal bleeding is a very rare manifestation. The case of a 61-year-old woman with symptoms of weight loss, abdominal distension, nausea, vomiting and long hair is presented. Tomographically, a wall thickening of jejunal loops with contrast uptake was evidenced, a finding that was corroborated by a double-balloon anterograde stereoscopy in which multiple were evidenced. The pathology shows distorted and ulcerated villous architecture with positive histochemistry for Congo Red and LAMBDA (+++) immunohistochemistry. In addition, bone marrow aspirate and bone biopsy compatible with infiltration of Lambda chain monoclonal multiple myeloma were performed. During the hospital stay, the patient developed complications such as chronic malnutrition, recurrent infection and several episodes of intestinal subocclusion; characterized by intestinal pneumatosis; due to multiple episodes of these complications, the patient died. Within clinical practice in gastroenterology, intestinal amyloidosis as part of the differential diagnosis of upper gastrointestinal bleeding is infrequent, so a history of diagnosis of multiple myeloma or other monoclonal gammopathy associated with light chains is crucial for early diagnosis and adequate treatment.

RESUMO

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.

RESUMO

Nuestro objetivo fue desarrollar un test diagnóstico para predecir la etiología de la Hemorragia Digestiva Alta Variceal (HDAV). Realizamos un estudio de cohorte retrospectivo. Se revisaron historias clínicas de pacientes mayores de 18 años con Hemorragia Digestiva Alta (HDA) que acudieron al servicio de emergencia del Hospital Cayetano Heredia (HCH) de Lima-Perú entre el 2019 a 2022, se recolectaron datos demográficos, de laboratorio y clínicos; posteriormente, se identificaron variables predictivas de HDAV mediante una regresión logística múltiple. A cada variable con capacidad predictiva se les asignó un puntaje con un punto de corte y sirvió para construir una escala predictiva de HDAV. Se incluyeron 197 historias clínicas de pacientes con HDA, de los cuales 127 (64%) tuvieron sangrado de causa no variceal, y, 70 (36%), variceal. Se identificaron 4 factores predictivos independientes: hematemesis (vómito rojo) (OR: 4,192, IC 95%: 1,586-11,082), recuento de plaquetas (OR: 3,786, IC 95%: 1,324-10,826), antecedente de HDA (OR: 2,634, IC 95%: 1,017-6,820), signos de enfermedad hepática crónica (OR: 11,244, IC 95%: 3,067-35,047), con los que se construyó una escala predictiva, con un punto de corte >7 y ≤7; que mostró una sensibilidad, especificidad, valor predictivo positivo, valor predictivo negativo, cociente de probabilidad positivo, y, negativo de 58,6%, 90,6%, 77,4%, 79,9%, 6,20, y 0,46 respectivamente. En conclusión, la escala predictiva con un punto de corte >7 es útil para predecir la presencia de la HDAV en pacientes que acuden a la emergencia por HDA.

Our objective was to develop a diagnostic test to predict the etiology of Variceal Upper Gastrointestinal Bleeding (VUGIB). We conducted a retrospective cohort study. Medical records of patients over 18 years of age with Upper Gastrointestinal Bleeding (UGIB) who attended the emergency service of Hospital Cayetano Heredia (HCH) in Lima-Peru between 2019 and 2022 were reviewed; demographic, laboratory and clinical data were collected. Subsequently, predictive variables of variceal upper gastrointestinal bleeding (VUGIB) were identified using multiple logistic regression. Each variable with predictive capacity was assigned a score with a cut-off point and served to build a predictive scale for VUGIB. 197 medical records of patients with UGIB were included, of which 127 (64%) had non-variceal bleeding, and 70 (36%), variceal. Four independent predictors were identified: hematemesis (red vomit) (OR: 4,192, 95% CI: 1.586-11.082), platelet count (OR: 3.786, 95% CI: 1.324-10.826), history of UGIB (OR: 2.634, 95% CI: 1.017-6.820), signs of chronic liver disease (OR: 11.244, 95% CI: 3.067-35.047), with which a predictive scale was constructed, with a cut-off point >7 and ≤7; which showed a sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative of 58.6%, 90.6%, 77.4%, 79.9%, 6.20, and 0.46 respectively. In conclusion, the predictive scale with a cut-off point >7 is useful for predicting the presence of VUGIB in patients who attend the emergency room for UGIB.

RESUMO

BACKGROUND: Acute esophageal variceal hemorrhage (AEVH) is a common complication of cirrhosis and might precipitate multi-organ failure, causing acute-on-chronic liver failure (ACLF). AIM: To analyze if the presence and grading of ACLF as defined by European Society for the Study of the Liver-Chronic Liver Failure (EASL-CLIF) is able to predict mortality in cirrhotic patients presenting AEVH. METHODS: Retrospective cohort study executed in Hospital Geral de Caxias do Sul. Data from medical records from 2010 to 2016 were obtained by searching the hospital electronic database for patients who received terlipressin. Medical records were reviewed in order to determine the diagnosis of cirrhosis and AEVH, including 97 patients. Kaplan-Meier survival analysis was used for univariate analysis and a stepwise approach to the Cox regression for multivariate analysis. RESULTS: All- cause mortality for AEVH patients was 36%, 40.2% and 49.4% for 30-, 90- and 365-day, respectively. The prevalence of ACLF was 41.3%. Of these, 35% grade 1, 50% grade 2 and 15% grade 3. In multivariate analysis, the non-use of non-selective beta-blockers, presence and higher grading of ACLF and higher Model for End-Stage Liver Disease scores were independently associated with higher mortality for 30-day with the addition of higher Child-Pugh scores for 90-day period. CONCLUSION: Presence and grading of ACLF according to the EASL-CLIF criteria was independently associated with higher 30- and 90-day mortality in cirrhotic patients admitted due to AEVH.

RESUMO

PURPOSE: To investigate the association between the use of antidepressants and the risk of upper gastrointestinal tract bleeding (UGIB). METHODS: A Case-control study was conducted in a Brazilian hospital complex. Cases were defined as patients with a diagnosis of UGIB and controls as patients admitted for reasons unrelated to gastrointestinal bleeding, gastric concerns, or complications associated with low-dose aspirin (LDA) or nonsteroidal anti-inflammatory drugs (NSAIDs) use. Sociodemographic and clinical data, comorbidities, drug therapy in use (long-term use and self-medication), and lifestyle habits were recorded through face-to-face interviews. Two groups were defined: use of antidepressants in general and use of antidepressants according to their affinity for serotonin transporters. The presence of synergism between the concomitant use of antidepressants and LDA or NSAIDs on the risk of UGIB was also explored. FINDINGS: A total of 906 participants were recruited (200 in the case group and 706 in the control group). The use of antidepressants was not associated with the risk of UGIB (odds ratio [OR] = 1.503; 95% CI, 0.78-2.88) or the use of antidepressants with high affinity for serotonin receptors (OR = 1.983; 95% CI, 0.81-4.85). An increased risk of UGIB was observed in concomitant users of antidepressants and LDA (OR = 5.489; 95% CI, 1.60-18.81) or NSAIDs (OR = 18.286; 95% CI, 3.18-105.29). Despite the lack of significance, the use of antidepressants appears to be a positive modifier of UGIB risk in LDA and NSAID users. IMPLICATIONS: These findings indicate an increased risk of UGIB in concomitant users of antidepressants and LDA or NSAIDs, suggesting the need to monitor antidepressant users, especially those most likely to develop UGIB. In addition, further studies with larger sample sizes are needed to confirm these findings.

RESUMO

Presentamos el caso de un paciente masculino de 32 años con antecedente de Neurofibromatosis tipo 1, que se presenta por hemorragia de intestino delgado activo, diagnosticada inicialmente al observar sangrado en ileoscopía, al cursar con inestabilidad hemodinámica se realiza angiotomografía abdominal identificando a nivel de yeyuno medio una masa con captación de contraste y sangrado activo por lo cual se realiza una angiografía con embolización arterial de la rama que irriga dicha zona. Con el paciente estable, se realizó una enteroscopía anterógrada de doble balón, observando una lesión subepitelial, ulcerada, se realiza tatuaje endoscópico y finalmente se envía a cirugía para resección mediante laparoscopia. El estudio anatomopatológico fue compatible con un tumor estromal gastrointestinal (GIST) yeyunal.

We present the case of a 32-year-old male patient with a history of Neurofibromatosis type 1, who presented with active small bowel bleeding, initially diagnosed by observing bleeding in ileoscopy, presenting with hemodynamic instability, abdominal angiotomography was performed, identifying a mass with contrast enhancement and active bleeding at the middle jejunum level, for which an angiography with arterial embolization of the branch that supplies said area is performed. With the patient stable, a double-balloon antegrade enteroscopy was performed, observing a subepithelial, ulcerated lesion, endoscopic tattooing was performed and finally surgery was sent for resection by laparoscopy. The pathology study was compatible with a jejunal gastrointestinal stromal tumor (GIST).

RESUMO

Pancreatic cancer is a malignant neoplasm with a poor prognosis. When it manifests clinically with cold jaundice, general repercussion or dyspepsia, it usually corresponds to a locally advanced tumor. Enterorrhagia as a form of presentation of pancreatic cancer is extremely infrequent; it corresponds to a severe form with an ominous prognosis. We present the case of a 61-year-old man who attended emergency service for enterorrhagia associated with organic abdominal pain and general repercussions, to whom a diagnosis of pancreatic tail cancer was diagnosed. Colonoscopy revealed mucosal infiltration with intense edema, erythema, necrosis, and spontaneous bleeding at the level of the splenic exure of the colon. Histology conrmed colonic infiltration by pancreatic neoplasm. Computed tomography allowed staging in stage IV. Palliative surgical treatment was performed, with a survival of 3 months.

El cáncer de páncreas corresponde a una neoplasia maligna con pobre pronóstico. Cuando se manifiesta clínicamente con ictericia fría, repercusión general o dispepsia, habitualmente corresponde a un tumor localmente avanzado. La enterorragia como forma de presentación del cáncer de páncreas es extremadamente infrecuente, corresponde a una forma grave y de pronóstico ominoso. Se presenta el caso de un hombre de 61 años que consultó por enterorragia asociada a dolor abdominal de características orgánicas y repercusión general, en el que se realizó diagnóstico de cáncer de cola de páncreas. La colonoscopía evidenció a nivel del ángulo esplénico del colon, infiltración mucosa con intenso edema, eritema, necrosis y sangrado espontáneo. La histología confirmó la infiltración colónica por neoplasma de páncreas. La tomografía computarizada permitió su estadificación en estadio IV. Se realizó tratamiento quirúrgico paliativo, con una sobrevida de 3 meses.

RESUMO

Introducción. El angiosarcoma es una neoplasia vascular originada a nivel del endotelio, de baja frecuencia, conocido por su agresividad y crecimiento acelerado. Alcanza solo el 1 al 2 % del total de los sarcomas. La presentación gastrointestinal es infrecuente y su incidencia es poco conocida debido al escaso reporte de casos en la literatura. Suele identificarse en etapas avanzadas debido a la dificultad del diagnóstico histopatológico por sus características morfológicas, siendo necesario aplicar tinciones especiales o estudio inmunohistoquímico. Caso clínico. Por su interés y singularidad, presentamos el caso de un paciente masculino de 54 años, quien consultó con hemorragia digestiva profusa, anemización y requerimiento de terapia transfusional. Resultados. Durante el proceso diagnóstico, en la endoscopia encontraron diversas lesiones multifocales que se extendían por gran parte del tracto gastrointestinal. El estudio histopatológico mostró angiosarcoma gastrointestinal. Discusión. El angiosarcoma del tracto gastrointestinal es extremadamente infrecuente, de difícil diagnóstico y bajas posibilidades de manejo curativo, con opciones terapéuticas limitadas, lo que configura un mal pronóstico a corto plazo

Introduction. Angiosarcoma is a vascular neoplasm originating from endothelial cells, known for its aggressiveness, accelerated growth and reduced frequency. Reach only 1 to 2% of total sarcomas. Gastrointestinal presentation is extremely rare, the true incidence is poorly known, due to the limited reports of this entity in the literature. It is usually identified in advanced stages in view of the difficulty of the histopathological diagnosis, attributable to its morphological characteristics, being necessary to apply special stains or immunohistochemical study. Case report. Due to their interest and uniqueness, we present the case of a 54-year-old male patient, who presented with a profuse gastrointestinal bleeding, anemia, and requirement for transfusion therapy. Results. The endoscopy detected several multifocal lesions that extended most of the gastrointestinal tract. The histopathological study showed gastrointestinal angiosarcoma. Discussion. Angiosarcoma of the gastrointestinal tract is extremely uncommon, difficult to diagnose and has low possibilities of curative management, with limited therapeutic options, which configures a poor prognosis in the short term

RESUMO

ABSTRACT Background: We evaluated the association between polymorphisms in the tumor necrosis factor alpha (TNF-α) (-G308A) gene and upper gastrointestinal bleeding (UGIB) in schistosomiasis. Methods: This was a transverse study involving 294 Brazilian patients infected with Schistosoma mansoni. Results: The homozygous A/A genotype in TNF-α (-G308A) showed a risk association (prevalence ratio = 1.90, p = 0.008) with UGIB. There was no statistically significant difference in serum TNF-α levels between the clinical groups. Conclusions: The polymorphic TNF-α (-G308A) can be a risk factor for UGIB, in addition to being a potentially predictive factor for the severity of UGIB in schistosomiasis.

RESUMO

SUMMARY OBJECTIVE: Gastrointestinal bleeding is an important part of gastrointestinal emergencies. This study aimed to examine the association between ABO blood groups and mortality in patients who were admitted to the emergency department and diagnosed with upper gastrointestinal bleeding. METHODS: The patients with upper gastrointestinal bleeding in the emergency department of a tertiary hospital in Turkey and the data of healthy blood donors were studied. The data of these patients were analyzed, and it was determined that the primary outcome was in-hospital mortality. RESULTS: The study was completed with 274 patients and 274 control group. The mean age of these patients was 65.1±18.2 years, and 64.2% of patients were males. It was found that the in-hospital mortality rate of patients with O blood group (16.2%) was statistically significantly higher than non-O blood group (7.5%) (p:0.032). CONCLUSION: The study concluded that the mortality rate of gastrointestinal bleeding patients with O blood group was higher compared to patients with other blood groups. Physicians can use ABO blood groups to predict mortality risk in gastrointestinal bleeding.

RESUMO

SUMMARY OBJECTIVE: The aim of the present study was to evaluate the outcomes of cirrhotic patients undergoing transjugular intrahepatic portosystemic shunt. METHODS: A retrospective longitudinal observational study was carried out evaluating 38 cirrhotic patients undergoing transjugular intrahepatic portosystemic shunt. The outcomes were evaluated in an outpatient follow-up period of 3 months. The assumed significance level was 5%. RESULTS: The indications for transjugular intrahepatic portosystemic shunt were refractory ascites in 21 (55.3%), variceal hemorrhage in 13 (34.2%), and hydrothorax in 4 (10.5%) patients. There was development of hepatic encephalopathy in 10 (35.7%) patients after transjugular intrahepatic portosystemic shunt. From the 21 patients with refractory ascites, resolution was observed in 1 (3.1%) patient, and in 16 (50.0%) patients, there was ascites control. Regarding transjugular intrahepatic portosystemic shunt after variceal bleeding, 10 (76.9%) patients remained without new bleeding or hospitalizations in the follow-up period. The global survival in the follow-up period in patients with and without hepatic encephalopathy was 60 vs. 82%, respectively (p=0.032). CONCLUSION: Transjugular intrahepatic portosystemic shunt can be considered in decompensated cirrhotic patients; however, the development of hepatic encephalopathy which can shorten survival should be focused.

RESUMO

SUMMARY OBJECTIVE: The aim of this study was to evaluate the performance of the Charlson Comorbidity Index ≥2, in-hospital onset, albumin <2.5 g/dL, altered mental status, Eastern Cooperative Oncology Group performance status ≥2, steroid use score in predicting mortality in patients with nonvariceal upper gastrointestinal bleeding and compare it with the Glasgow-Blatchford score; the albumin, international normalized ratio; alteration in mental status, systolic blood pressure, and age 65 score; the age, blood tests, and comorbidities score; and Complete Rockall score. METHODS: The data of patients with acute upper gastrointestinal bleeding who visited the emergency department during the study period were obtained from the hospital automation system by using the classification of disease codes and analyzed in this retrospective study. Adult patients with endoscopically confirmed nonvariceal upper gastrointestinal bleeding were included in the study. Patients with bleeding from the tumor, bleeding after endoscopic resection, or missing data were excluded. The prediction accuracy of the Charlson Comorbidity Index ≥ 2, in-hospital onset, albumin < 2.5 g/dL, altered mental status, Eastern Cooperative Oncology Group performance status ≥ 2, steroid use score was calculated using the area under the receiver operating characteristic curve and compared with that of Glasgow-Blatchford score, the albumin, international normalized ratio; alteration in mental status, systolic blood pressure, and age 65 score, the age, blood tests, and comorbidities score, and Complete Rockall score. RESULTS: A total of 805 patients were included in the study, and the in-hospital mortality rate was 6.6%. The performance of the Charlson Comorbidity Index ≥ 2, in-hospital onset, albumin < 2.5 g/dL, altered mental status, Eastern Cooperative Oncology Group performance status ≥ 2, steroid use score (area under the receiver operating characteristic curve 0.812, 95%CI 0.783-0.839) was better than Glasgow-Blatchford score (area under the receiver operating characteristic curve 0.683, 95%CI 0.650-0.713, p=0.008), and similar to the the age, blood tests, and comorbidities score (area under the receiver operating characteristic curve 0.829, 95%CI 0.801-0.854, p=0.563), the albumin, international normalized ratio; alteration in mental status, systolic blood pressure, and age 65 score (area under the receiver operating characteristic curve 0.794, 95%CI 0.764-0.821, p=0.672), and Complete Rockall score (area under the receiver operating characteristic curve 0.761, 95%CI 0.730-0.790, p=0.106). CONCLUSION: The performance of the Charlson Comorbidity Index ≥ 2, in-hospital onset, albumin < 2.5 g/dL, altered mental status, Eastern Cooperative Oncology Group performance status ≥ 2, steroid use score in predicting in-hospital mortality for our study population is better than Glasgow-Blatchford score and similar to the the age, blood tests, and comorbidities score, the albumin, international normalized ratio; alteration in mental status, systolic blood pressure, and age 65 score, and Complete Rockall score.

RESUMO

Rapunzel syndrome is an unusual and rare disease that occurs in young people, caused by intragastric accumulation of ingested hair (gastric trichobezoar) that keeps stuck in the gastric lumen and extends to the small intestine, associated with trichophagia. We report the case of a 25-year-old female patient with a history of trichophagia who is admitted in our institution with abdominal pain, distention, nausea, weight loss and concomitant upper gastrointestinal bleeding. Preoperative diagnosis was made by prior abdominal computed tomography scan with duodenal extension. Success surgical laparotomy and multimodal psychiatric follow up was made. This entity must be considered as a differential diagnosis with Acute Abdomen with Bowel obstruction and upper gastrointestinal bleeding.

El síndrome de Rapunzel es una enfermedad inusual y rara que se presenta en personas jóvenes, caracterizada por un acúmulo de cabello ingerido (tricobezoar gástrico) y confinado generalmente a la cámara gástrica que se extiende al intestino delgado, asociada a tricofagia. Reportamos el caso de una paciente de 25 años con antecedente de tricofagia que ingresa a un centro de salud en curso de dolor, distensión abdominal y datos de obstrucción intestinal asociado a hemorragia digestiva alta. Con documentación preoperatoria por tomografía computada abdominal de un tricobezoar con extensión duodenal, el cual se extrae por laparotomía. La paciente se remite para manejo multimodal por servicio de psiquiatría. Es una afección para tener en cuenta como diagnóstico diferencial en los cuadros de abdomen agudo quirúrgico, de la mano con obstrucción intestinal y sangrado gastrointestinal.

RESUMO

Introducción: Los medicamentos antiulcerosos son utilizados frecuentemente en pacientes hospitalizados, sin embargo, a menudo este uso no está indicado. Objetivo: Describir la frecuencia de prescripción e indicación de medicamentos para prevenir el sangrado gastrointestinal en pacientes hospitalizados. Materiales y métodos: Estudio de corte trasversal, descriptivo, prospectivo del servicio de Medicina Interna de la Sociedad de Cirugía de Bogotá- Hospital de San José de Bogotá, Colombia. Se excluyeron pacientes con diagnóstico de sangrado gastrointestinal o antecedente de alergia a los medicamentos antiulcerosos. Se recolectaron datos demográficos, así como fármacos prescritos. Se determinó si la indicación del fármaco era adecuada y se identificó el tipo de error de prescripción. Resultados: Se incluyeron 179 pacientes, 102 (57%) mujeres. Promedio de edad de 61,3 años (±20,2). El principal diagnóstico de ingreso fue enfermedad infecciosa 76 (42,4%). Del total de pacientes, 165 (92,17%) recibieron medicamento para prevención del sangrado gastrointestinal. La indicación fue adecuada en 75 pacientes (41,89%). El error más frecuente fue el uso en pacientes de bajo riesgo de sangrado, 101 (97,1%). Conclusión: Un alto porcentaje de los pacientes recibió medicación para la prevención del sangrado gastrointestinal. En aproximadamente la mitad de estos no estaba indicada.

Introduction: Anti-ulcer medications are frequently used in hospitalized patients, yet their use is not usually indicated. Objective: To describe the frequency of prescription and indication of medications to prevent gastrointestinal bleeding in hospitalized patients. Materials and methods: A cross-sectional, descriptive, prospective study was carried out in the Internal Medicine service of the Surgery Society of Bogota-San Jose Hospital of Bogota (Colombia). Excluded patients were those with either a gastrointestinal bleeding diagnosis or a history of allergy to anti-ulcer medications. Demographic data and information regarding prescribed medications were collected. It was determined whether the medicine indication was adequate and the type of prescription error was identified. Results: 179 patients were included in the study, 57% (102) of which were women. The average age was 61.3 (±20.2) years old. Infectious disease was the main admission diagnosis (76; 42.4%). A 92.17% (165) of the total number of patients received medications to prevent gastrointestinal bleeding. This indication was adequate for 75 (41.89%) patients. The most frequent error was their use in bleeding low-risk patients (101; 97.1%). Conclusion: A high percentage of patients received medication to prevent gastrointestinal bleeding. However, in about half of these patients it was not indicated.

RESUMO

Typhlitis, is also known as neutropenic enterocolitis, affects the cecum and distal ileum. It was frequently encountered in pediatric patients who were undergoing treatment for leukemia. Nonetheless, it can affect adult patients, regardless of the cause of the immunosuppression. We report the case of a 20-year-old patient who was receiving chemotherapy for Osteosarcoma, who had a 6-day history of nausea and vomiting, fever sensation, diarrhea, and diffuse abdominal pain. Physical examination was relevant for hemodynamic instability, a distended and tender abdomen predominantly in the right iliac fossa. The laboratory workup showed severe neutropenia, thrombocytopenia, and electrolyte disturbances. The image studies evidenced edema of the ascending colon and cecum. Treatment was started with vasopressor support, correction of electrolyte alterations, blood cell and platelet transfusion, G-CSF, hydration, broad spectrum antibiotic therapy, initially with adequate clinical and laboratory response. After a few days, he presented lower gastrointestinal bleeding which was treated by conservative management. In conclusion, typhlitis must be suspected in every patient developing neutropenia as a reaction to chemotherapy and who also presents gastrointestinal symptoms, such as nausea, vomiting, diarrhea, and intense abdominal pain.

La tiflitis o también denominada enterocolitis neutropénica afecta el ciego e íleon distal. Fue descrita comúnmente en pacientes pediátricos sometidos a tratamiento para leucemia; sin embargo, puede afectar al paciente adulto independiente de la causa que origine la inmunosupresión. Presentamos el caso de un paciente de 20 años con antecedente de osteosarcoma, quien acude con tiempo de enfermedad de 6 días caracterizado por náuseas y vómitos, sensación de alza térmica, diarrea y dolor abdominal difuso. Al examen físico se encuentra hemodinámicamente inestable, abdomen distendido y se corrobora el dolor abdominal a predominio en fosa iliaca derecha. Los exámenes de laboratorio mostraron neutropenia severa, trombocitopenia y alteraciones hidroelectrolíticas. En los estudios de imágenes la TC evidenció edema de asas delgadas, así como edema de pared del colon ascendente y ciego. Se inició tratamiento con soporte vasopresor, corrección de alteraciones hidroelectrolíticas, transfusión de paquetes globulares y plaquetas, G-CSF, hidratación, terapia antibiótica de amplio espectro, inicialmente con adecuada respuesta clínica y laboratorial. Al cabo de unos días presentó hemorragia digestiva baja como complicación que fue tratada mediante manejo conservador. En conclusión, la tiflitis debe sospecharse en todo paciente que desarrolla neutropenia luego de quimioterapia y que presenta síntomas gastrointestinales como náuseas, vómitos, diarrea y dolor abdominal intenso. El manejo conservador, en pacientes con hemorragia digestiva y tiflitis, que involucra corrección de coagulopatía, transfusión de paquetes globulares e hidratación, puede ser el adecuado en pacientes que no cursan con inestabilidad hemodinámica y logran controlar el sangrado.

RESUMO

BACKGROUND: Bisphosphonates are the mainstay of osteoporosis treatment, but their use for patients with esophageal varices has been avoided due to the risk of esophagitis, which may cause variceal bleeding. Since most clinical trials assessing osteoporosis treatment last 2-3 years, this study aimed to evaluate a 2-year risedronate treatment for patients with esophageal varices and liver cirrhosis. METHODS: The study received Institutional Review Board approval, and the sample was divided into two groups according to bone mineral density (BMD). Cirrhosis severity and endoscopic findings at baseline were similar between the groups. The intervention group had 51 patients with osteoporosis, who received oral risedronate 35 mg weekly plus calcium and vitamin D supplements. The control group had 51 patients with osteopenia, receiving only the supplements. Scheduled esophagogastroduodenoscopies and BMD measurements were carried out. RESULTS: The adjusted esophagitis risk was higher in the intervention group; however, none of the subjects had digestive bleeding. Lumbar spine BMD increased in the intervention group (- 3.06 ± 0.71 to - 2.33 ± 0.90; p < 0.001) and in the control group (- 1.38 ± 0.77 to - 1.10 ± 1.05; p = 0.012). Femoral neck BMD did not change in the intervention group (- 1.64 ± 0.91 to - 1.71 ± 0.95; p = 0.220), but tended to decrease in the control group (- 1.00 ± 0.74 to - 1.09 ± 0.82; p = 0.053). CONCLUSION: Oral risedronate was effective and did not cause gastrointestinal bleeding in cirrhotic patients with esophageal varices under endoscopic surveillance.
