Lower Digestive Tract Bleeding in a Patient with Behçet's Disease: A Case Report

Behçet's disease is a chronic, multisystemic, and relapsing inflammatory pathology that frequently manifests with oral and genital ulcers and ocular and skin lesions. It rarely exhibits gastrointestinal involvement, which varies depending on the affected gastrointestinal segment; these have in common the predominance of ulcerated lesions and, consequently, a greater risk of bleeding from the digestive tract. A clinical case of a 28-year-old female patient who consulted for a clinical picture of melenic stools and oral ulcers is described. As a crucial clinical history, she had been diagnosed with Behçet's disease since adolescence, associated with severe gastrointestinal complications. An esophagogastroduodenoscopy was performed with findings of antral erythematous gastropathy and a colonoscopy with a report of ulcerated ileitis. Treatment with azathioprine and corticosteroids was indicated, significantly improving the clinical picture.

La enfermedad de Behçet es una patología inflamatoria crónica, multisistémica y recidivante que se manifiesta frecuentemente con úlceras orales y genitales, y lesiones oculares y cutáneas. En raras ocasiones presenta compromiso gastrointestinal y este varía dependiendo del segmento gastrointestinal afectado; estas enfermedades tienen en común el predominio de lesiones ulceradas y, consecuentemente, un mayor riesgo de sangrado de las vías digestivas. Se describe un caso clínico de una paciente femenina de 28 años que consultó por un cuadro clínico de deposiciones melénicas y úlceras orales. Como antecedente clínico de importancia presentó diagnóstico de enfermedad de Behçet desde la adolescencia asociado a complicaciones gastrointestinales graves. Se realizó una esofagogastroduodenoscopia con hallazgos de gastropatía eritematosa antral y una colonoscopia con reporte de ileítis ulcerada. Se indicó el tratamiento con azatioprina y corticoides con una mejoría significativa del cuadro clínico.

Cuando la ileítis de Crohn no es solo ileítis / When Crohn's ileitis is not just ileitis

RESUMEN En una minoría de pacientes con ileítis de Crohn (EC) de larga evolución, la recrudescencia de los síntomas puede representar una neoplasia ileal, con una clínica indistinguible de la enfermedad basal y por ende poco sospechada. Frecuentemente la patología tumoral se diagnostica en la pieza quirúrgica, tras una intervención por hemorragia u obstrucción intestinal. El objetivo de este trabajo es destacar la importancia de un diagnóstico diferencial ante una ileítis terminal en un paciente con EC con mala respuesta a tratamiento médico.

ABSTRACT In a minority of patients with long-standing Crohn's ileitis, the recrudescence of symptoms may represent a neoplasm involving the ileum that is clinically indistinguishable from the baseline disease and therefore poorly suspected. Tumors are often diagnosed in the surgical specimen, after an intervention due to bleeding or bowel obstruction. The aim of this study is to emphasize the importance of the differential diagnoses of terminal ileitis in a patient with CD with poor response to medical treatment.

Ileites - endoscopistas e patologistas falam a mesma língua? / Ileitis - do endoscopist and pathologist speak the same language?

ABSTRACT BACKGROUND: Ileitis is defined as an inflammation of the ileum, which is evaluated during colonoscopy. Biopsies should be performed on altered ileus, aiding to the diagnosis. OBJECTIVE: Evaluate the correlation of anatomopathological findings on ileitis between pathologists and endoscopists. METHODS: A retrospective, cross-sectional study, between 2013 and 2017. Examination report, indications for colonoscopy, and medical records were evaluated to identify whether the colonoscopic findings were clinically significant. Anatomopathological samples were reviewed by a pathologist expert in gastrointestinal tract. Patients over 18 years of age who had undergone ileoscopy were included, whereas patients below 18 years of age and those with previous intestinal resections were excluded. The correlation was assessed using the kappa coefficient index. RESULTS: A total of 5833 colonoscopies were conducted in the study period and 3880 cases were included. Ileal alterations were observed in 206 cases, with 2.94% being clinically significant. A hundred and sixty three biopsies were evaluated using the kappa index, resulting in agreement among pathologists of 0.067 and among pathologist and endoscopist of 0.141. CONCLUSION: It was observed that despite the low concordance between pathologists and endoscopists, there was no change in patient outcomes. This study confirms the importance of knowledge of the main anatomopathological changes related to ileitis by pathologists and endoscopists, making the best diagnosis and follow-up.

RESUMO CONTEXTO: Ileíte é definida como uma inflamação ileal, que pode ser avaliada durante a colonoscopia. Biópsias devem ser realizadas em íleos alterados, acrescentando na definição diagnóstica. OBJETIVO: Avaliar a correlação de achados anatomopatológicos das ileítes entre patologistas e endoscopistas. MÉTODOS: Estudo retrospectivo, transversal, entre os anos de 2013 e 2017. Foram avaliados laudos de exames, indicações e prontuários para identificar quando os achados colonoscópicos foram significativos. As amostras de anatomopatologia foram revisadas por um patologista especialista em trato gastrointestinal. Foram incluídos pacientes acima de 18 anos, com ileoscopia, e excluídos pacientes menores de 18 anos e os com ressecções intestinais prévias. A correlação foi avaliada utilizando-se o coeficiente kappa. RESULTADOS: Durante o período do estudo foram realizadas 5833 colonoscopias, das quais 3880 foram incluídas. Alterações ileais foram observadas em 206 casos, com 2,94% sendo clinicamente significativo. Cento e sessenta e três biópsias foram avaliadas, resultando em coeficiente kappa entre patologistas de 0,067 e entre patologista e endoscopista de 0,141. CONCLUSÃO: Foi observado que a despeito da baixa concordância entre patologistas e endoscopistas, não houve mudança no desfecho clínico do paciente. Esse estudo confirma a importância do conhecimento dos achados anatomopatológicos principais das ileítes entre patologistas e endoscopias, fazendo o melhor diagnóstico e seguimento.

Ileoscopia: quando a avaliação ileal não é mandatória durante a colonoscopia / Ileoscopy: when ileal evaluation is not mandatory during colonoscopy

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.

Ileítis terminal por Yersinia enterocolitica: diagnóstico diferencial con la enfermedad de Crohn en un varón de 12 años / Terminal ileitis due to Yersinia enterocolitica: differential diagnosis with Crohn ́s disease in a 12-year-old male

Yersinia enterocolitica es un bacilo Gram-negativo causante de infección intestinal en los humanos. Se presenta con diferentes cuadros clínicos que obligan a descartar una variedad de etiologías, lo cual, a veces, hace difícil alcanzar un diagnóstico correcto en forma oportuna.Se expone el caso de un varón adolescente con dolor en la fosa ilíaca derecha a partir de una ileítis terminal con hallazgos similares a la enfermedad de Crohn, que se diagnosticó, finalmente, como infección por Yersinia enterocolitica. Se destaca la utilidad de los diferentes métodos auxiliares empleados.

Yersinia enterocolitica is a gram-negative rod causing intestinal infection in humans. It shows different clinical pictures with many different etiologies to be ruled-out, which sometimes makes it difficult to reach a timely and correct diagnosis. We report the case of an adolescent boy presenting with right lower quadrant pain from terminal ileitis with endoscopic findings akin to Crohn ́s disease finally diagnosed as Yersinia enterocolitica, highlighting the usefulness of the different ancillary methods employed.

Ileítis como presentación de linfoma en síndrome de Wiskott-Aldrich / Ileitis as presentation of lymphoma in Wiskott-Aldrich syndrome

El síndrome de Wiskott-Aldrich (SWA) es un raro síndrome de inmunodeficiencia primaria ligado al cromosoma X que se asocia con aumento de incidencia de infecciones, trastornos autoinmunes y neoplasias. Se presenta el caso de un varón de 41 años con diagnóstico de síndrome de Wiskott-Aldrich y cuadro de ileítis como forma de presentación de un síndrome linfoproliferativo. La ileítis, en el contexto del paciente, representa un problema clínico dado el gran número de diagnósticos diferenciales (enfermedad inflamatoria intestinal, infecciones, neoplasias y enfermedades linfoproliferativas) por lo que suele requerir diagnóstico anatomopatológico y consideraciones particulares respecto al posterior tratamiento específico.

Wiskott-Aldrich syndrome is a rare X chromosome-linked primary immunodeficiency syndrome associated with an increased incidence of infections, autoimmune disorders and neoplasms. We present the case of a 41-year-old man with a diagnosis of Wiskott-Aldrich syndrome with ileitis as a form of presentation of a lymphoproliferative syndrome. The ileitis, in the context of the patient, represents a clinical challenge given the large number of differential diagnoses (inflammatory bowel disease, infections, neoplasms and lymphoproliferative diseases), so it usually requires anatomopathological diagnosis and particular considerations regarding the subsequent specific treatment.

Evaluation of terminal ileitis with energy spectrum CT / 中国医学影像技术

Objective: To observe the manifestations of terminal ileitis on gemstone energy spectrum CT imaging (GSI) and its diagnostic efficacy compared conventional CT enterography (CTE), so as to evaluate the diagnosis value of GSI for terminal ileitis. Methods: Data of 120 patients with suspected terminal ileum diseases were retrospectively analyzed, including 115 cases of pathologically proved diseases (72 cases of terminal ileum enteritis, 6 cases of ileum polyps or tumorlike lesions, 30 cases of ileum Crohn's disease and 7 cases of ileum tuberculosis) and 5 cases without obvious abnormality. Among them 70 patients received conventional CTE (CTE group) and 50 received GSI (GSI group). Imaging characteristics of terminal ileitis were observed and compared between 2 groups. The consistency of the results of 2 methods for detecting terminal ileitis with pathological results were analyzed, and their sensitivities and specificities were compared. ROC curves of 2 methods for detecting terminal ileitis were drawn, and their relative diagnostic efficacy were analyzed. Results: Compared with conventional CTE, the lesions were clearer on low keV single energy imaging. The energy spectrum curve and iodide maps clearly identified the lesion's wall, normal wall, the fluid in intestinal cavity and the adjacent fat tissue. The iodine concentration of terminal ileitis at the arterial and venous phase was (10.90±0.55)μg/cm3 and (14.33±0.75)μg/cm3, respectively. Conventional CTE showed poor, while GSI showed high consistency with the pathological results for detecting terminal ileitis (Kappa=0.35, 0.72, P=0.16, <0.01). The sensitivity and specificity of GSI (86.21%, 85.71%) were bith higher than those of conventional CTE (65.12%, 51.85%, χ2=3.97, 6.10, both P<0.05). The AUC of GSI (0.86) was higher than that of conventional CTE (0.57, Z=2.42, P=0.02). Conclusion: GSI could clearly show lesions of terminal ileitis, therefore having high diagnostic efficacy for detecting terminal ileitis.

Diffusion-weighted imaging and apparent diffusion coefficient values for evaluating terminal ileitis in patients with Crohn's disease / Imagem ponderada na sequência de difusão e coeficiente aparente de difusão na avaliação de inflamação ileal distal em pacientes com doença de Crohn

Abstract Objective: To determine the accuracy of diffusion-weighted imaging (DWI) in identifying terminal ileitis in patients with Crohn's disease. Materials and Methods: This was a retrospective study of 38 consecutive patients with Crohn's disease who underwent magnetic resonance enterography with DWI in a 3.0 T scanner. The patients were divided into two groups, on the basis of colonoscopy and biopsy findings: active inflammation; and inactive disease. Apparent diffusion coefficient (ADC) values were determined, as were the magnetic resonance index of activity (MaRIA) and the Clermont score. Results: Of the 38 patients evaluated, 18 (47%) had active inflammation. The patients with active inflammation showed greater restricted diffusion, more pronounced mucosal edema, greater wall thickening, a higher MaRIA, and a higher Clermont score than did those with inactive disease. The level of interobserver agreement (intraclass correlation coefficient) was excellent for the MaRIA and the Clermont score, whereas it was substantial for the ADC values. For identifying colonoscopy-proven inflammation, the best ADC cut-off point was 2.1 × 10−3 mm2/s, which had a sensitivity of 88.8% and a specificity of 95.0%, whereas DWI presented an overall accuracy of 89.4%, with a sensitivity of 88.9% and a specificity of 90.0%. Conclusion: Visual analysis of the DWI sequence has good accuracy in detecting terminal ileitis in patients with Crohn's disease. In addition, low ADC values have good sensitivity for detecting colonoscopy-proven inflammation.

Resumo Objetivo: Determinar a acurácia da ressonância magnética com difusão na identificação de sinais de inflamação ileal distal em pacientes com doença de Crohn. Materiais e Métodos: Estudo retrospectivo com 38 pacientes consecutivos com doença de Crohn que foram submetidos a enterografia por ressonância magnética. Os pacientes foram alocados em duas categorias, utilizando a positividade na endoscopia e na biópsia como referência: doença ativa ou não ativa. Foram determinados os valores do coeficiente de difusão aparente (ADC), assim como o magnetic resonance index of activity (MaRIA) e o escore Clermont. Resultados: Dezoito pacientes (47%) apresentaram doença inflamatória ativa. Os pacientes com inflamação ativa tiveram maior restrição na difusão, edema de mucosa, espessamento de parede, MaRIA e escore Clermont quando comparados aos pacientes sem inflamação. A correlação de concordância interobservador foi excelente para o MaRIA e para o escore Clermont e considerável para o ADC. Os melhores pontos de corte no estudo para identificação de inflamação pela colonoscopia para o ADC foi 2,1 × 10-3 mm2/s, com sensibilidade de 88,8% e especificidade de 95,0%. A imagem ponderada em difusão apresentou acurácia de 89,4%, sensibilidade de 88,9% e especificidade de 90,0% em relação à identificação de inflamação na colonoscopia. Conclusão: A análise visual das sequências de difusão possui boa acurácia na detecção de inflamação ileal distal em pacientes com doença de Crohn. Valores baixos de ADC possuem boa sensibilidade na detecção de inflamação na colonoscopia.

Tylosin injectable for the treatment of porcine proliferative enteropathy in experimentally inoculated pigs / Tilosina injetável no tratamento da enteropatia proliferativa suína em leitões experimentalmente inoculados

Porcine proliferative enteropathy (PPE) is one of the most common enteric diseases in growing and finishing pigs. PPE is characterized by reduced growth performance, accompanied or not by diarrhea. PPE is highly prevalent in several countries of the Americas, Europe and Asia, causing high economic losses in swine herds. The most common form of PPE control in pigs is antibiotic therapy. The objective of this study was to evaluate a new product based on tylosin injectable (Eurofarma Laboratórios S.A.) to control PPE in experimentally inoculated animals. Sixty 5-week-old pigs with mean weight of 9.5kg were divided into two experimental groups of 30 animals: medication and control. All pigs were challenged with Lawsonia intracellularis, the etiologic agent of PPE, on day zero. Fecal score, body condition score, and behavior were daily evaluated. Pigs were weighted on days -2, 13 and 21 of the experiment. Pigs in the Medication Group received tylosin injectable 13 days after inoculation, in three doses with a 12-hour interval between them. Pigs in the Control Group received injectable saline solution following the same protocol. In the Control Group, 23pigs presented with diarrhea before day 13. After day 13, the number of diarrheic animals in this group was reduced to 17. In the Medication Group, 26 pigs presented with diarrhea in the initial period, and in the period after medication, only 11 animals had diarrhea. The score of gross intestinal PPE lesions in the Medication Group was lower than that in the Control Group (p=0.031). The Medication Group also showed lower score for Lawsonia intracellularis antigen-labeling by immunohistochemistry compared with that of the Control Group (p=0.032), showing lower level of infection. These results demonstrate that tylosin injectable (Eurofarma Laboratórios S.A.), administrated in three doses (1mL/20kg) every 12 hours, was effective for the control of PPE in experimentally inoculated pigs.(AU)

Enteropatia proliferativa suína (EPS), causada pela bactéria Lawsonia intracellularis, é uma das doenças entéricas mais comuns em suínos de recria e terminação. A EPS caracteriza-se por redução no desempenho dos animais, acompanhada ou não por diarreia. É uma doença altamente prevalente em diversos países da América, Europa e Ásia, provocando elevados prejuízos econômicos nos rebanhos suínos. A forma de controle da EPS mais adotada em rebanhos suínos é a antibioticoterapia. O objetivo deste estudo foi avaliar um novo produto à base de tilosina (Eurofarma Laboratórios S.A.) na forma injetável para controlar a EPS em animais experimentalmente inoculados. Foram utilizados 60 leitões, de cinco semanas de idade, com peso médio de 9,5kg, divididos em dois grupos experimentais (n=30), medicados e não medicados. Todos os leitões foram desafiados com Lawsonia intracellularis no dia zero. Avaliações clínicas de escore fecal, escore corporal e comportamento foram realizadas diariamente além da pesagem individual dos animais realizada nos dias -2, 13 e 21 do experimento. Os leitões do grupo medicado receberam tilosina injetável 13 dias após a inoculação em três doses com intervalo de 12 horas cada. Já os leitões do grupo não medicado receberam solução salina injetável com o mesmo protocolo. O grupo não medicado apresentou 23 animais com diarreia antes do dia 13 e 17 após este período. No grupo medicado, 26 animais apresentaram diarreia previamente à medicação e apenas 11 após a medicação a partir do dia 13. Os leitões medicados apresentaram extensão de lesão macroscópica, caracterizada por espessamento de mucosa intestinal, menor em comparação com o grupo não medicado (p=0,031). A imunomarcação para Lawsonia intracellularis foi menor no grupo medicado (p<0,032), mostrando redução no grau de infecção por L. intracellularis nos animais medicados. Estes resultados demonstram que a tilosina injetável (Eurofarma Laboratórios S.A.) (1mL/20kg) em três doses, a cada 12 horas, foi eficaz no tratamento da enteropatia proliferativa suína em animais experimentalmente inoculados.(AU)

Abdominal ultrasonography with color Doppler analysis in the assessment of ileal Crohn's disease: comparison with magnetic resonance enterography

BACKGROUND/AIMS: Consistently defining disease activity remains a critical challenge in the follow-up of patients with Crohn's disease (CD). We investigated the potential applicability of abdominal ultrasonography with color Doppler (USCD) analysis for the detection of morphological alterations and inflammatory activity in CD. METHODS: Forty-three patients with CD ileitis/ileocolitis were evaluated using USCD analysis with measurements obtained on the terminal ileum and right colon. Sonographic parameters included wall thickening, stricture, hyperemia, presence of intra-abdominal mass, and fistulas. Patients were evaluated for the clinical activity (Harvey-Bradshaw Index [HBI]), fecal calprotectin (FC) and C-reactive protein (CRP). The USCD performance was assessed using magnetic resonance enterography (MRE) as a criterion standard. RESULTS: Most measurements obtained with USCD matched the data generated with MRE; however, the agreement improved in clinically active patients where sensitivity, positive predictive value, and accuracy were >80%, considering wall thickening and hyperemia. Complications such as intestinal wall thickening, stricture formation, and hyperemia, were detected in the USCD analysis with moderate agreement with MRE. The best agreement with the USCD analysis was obtained in regard to FC, where the sensitivity, positive predictive value, and accuracy were >70%. The overall performance of USCD was superior to that of HBI, FC and CRP levels, particularly when considering thickening, stricture, and hyperemia parameters. CONCLUSIONS: USCD represents a practical noninvasive and low-cost tool for evaluating patients with ileal or ileocolonic disease, particularly in clinically active CD. Therefore, USCD might become a useful asset in the follow-up of patients with CD.

Typhoid Ileitis with Periappendicitis: A case report

Introduction@#Typhoid fever usually presents with prolong fever associated with constitutional symptoms of headache and abdominal pain. Patients living in far flung areas often downplayed this condition with a viral infection causing delay in diagnosis. We present a case of a 30-year-old male diagnosed with typhoid fever who developed upper gastrointesitinal bleeding with intraoperative finding of periappendicitis.@*Case presentation@#This is a case of a 30-year-old male patient presented in the emergency room with abdominal pain and high fever for three weeks. Physical examination showed he was fairly dehydrated with dry lips and tongue and abdominal examination revealed epigastric pain on deep palpation. Initially, his laboratory tests were unrevealing. Over the course of his confinement he was given multiple transfusion due to profused hematochezia and with sudden reduction in hematocrit count thus was referred to surgical service for emergency laparotomy. Intraoperative findings showed bleeding ulcers in the ileum accompanied by histologic findings of periappendicitis which originally thought of as acute suppurative appendicitis.@*Conclusion@#It is important to consider in patients with three or more weeks with typhoid fever its complications of intestinal bleeding. However, the finding of periappendicits contributes a rare and not easily diagnosed pathology which is not within the context of an enteric infection.

Crohn's disease versus Yersinia enterocolitica infection - case report - a difficult differential diagnosis / Doença de Crohn's × Yersinia enterocolitica - um difícil diagnóstico diferencial - relato de caso

ABSTRACT The aim of this report is to present an unusual case of Crohn's disease affecting the terminal ileum; whose principal differential diagnosis was Yersinia enterolocolitica infection, as the histological features of the resected ileum was common to both diseases. We also describe how the infectious etiology was discarded and the implications for the patient follow-up.

RESUMO O objetivo desse relato é analisar um caso incomum de doença de Crohn, cujo diagnóstico diferencial, com possível infecção por Yersinia enterocilítica, foi dificultado pela presença de alterações histológicas das duas doenças. Descrevemos como foi realizada a exclusão de causas infecciosas e as implicações no acompanhamento do paciente.

Enfermedad de Crohn ileal. Reporte de un caso / Ileal Crohn's Disease. A case report

El término Enfermedad Inflamatoria Intestinal (EII) incluye a un grupo de entidades clínicas que se caracterizan por ser procesos inflamatorios crónicos de etiología desconocida, y afectar primordialmente, aunque no de forma exclusiva, al intestino. Actualmente se reconocen varias entidades que se engloban en este concepto: Colitis Ulcerosa (CU), Enfermedad de Crohn (EC), Colitis Inclasificada (CI), Colitis Microscópica (CM) y Reservoritis (Pouchitis). La Enfermedad de Crohn puede afectar a cualquier tramo del intestino, siendo la localización más frecuente la Ileal y Colónica en forma simultánea. El proceso inflamatorio en la EC es transmural y sus síntomas fundamentales son la diarrea generalmente crónica y/o el dolor abdominal. Presentamos el caso de una mujer joven con una EC que compromete exclusivamente al ileon terminal, en la que se realizó el diagnóstico de EC ileal por la clínica, la endoscopía y la anatomía patológica, que respondió satisfactoriamente a la terapéutica instaurada, y se revisa el concepto de la EC con énfasis en su diagnóstico.

The term Inflammatory Bowel Disease (IBD) includes a group of clinical entities that are characterized by chronic inflammatory processes of unknown etiology, and primarily, but not exclusively, affecting the intestine. Currently, several entities are included in this concept: Ulcerative Colitis (UC), Crohn's Disease (CD), Unclassified Colitis (UC), Microscopic Colitis (CM) and Reservoritis (Pouchitis). Crohn's Disease can affect any part of the intestine, with the most frequent location being ileal and colonic simultaneously. The inflammatory process in CD is transmural and its fundamental symptoms are usually chronic diarrhea and/or abdominal pain. We present the case of a young woman with a CD that exclusively compromises the terminal Ileon, in whom the diagnosis of ileal CD was performed with the clinical data, the endoscopic procedure and the pathological study, who responded satisfactorily to the established therapy, and the concept of CD with an emphasis on its diagnosis is reviewed.

Trombosis venosa profunda en un paciente con enfermedad de Crohn ilealestenosante

Las enfermedades inflamatorias intestinales se asocian a manifestaciones extraintestinales. Dentro de estas manifestaciones, el tromboembolismo venoso, se presenta con un riesgo aproximadamente 3 veces mayor que en la población general. Reportamos el caso de un varón de 61 años con historia de dolor abdominal, diarrea crónica y fiebre, con leucocitosis, reacción inflamatoria en heces positiva, estenosis ileal parcial con múltiples úlceras en la enteroscopía y hallazgos histopatológicos compatibles con enfermedad de Crohn. El paciente evoluciona favorablemente con prednisona y azatioprina de mantenimiento, presentando en el quinto mes trombosis venosa profunda de ambos miembros inferiores, la cual mejora con anticoagulación plena

Inflammatory bowel disease is associated with extraintestinal manifestations. Among these manifestations is the venous tromboembolism which presents a risk three times more than that presented in general population. We report the case of a 61-year-old male with a history of abdominal pain, chronic diarrhea and fever, with leukocytosis, and fecal samples containing leukocytes, partial ileal stenosis with multiple ulcers in the enteroscopy, with histologic findings compatible with Crohn's disease. The patient has a good outcome with prednisone and maintenence azathioprine, presenting at the fifth month deep venous thrombosis of both lower extremities that resolvewith anticoagulation treatment

Interpretation of ileal biopsies.

The ileum is one of the most common sites of intestine to undergo endoscopic biopsy. However, even with the experienced histopathologists, a defi nite diagnosis can be achieved only in 18% cases. Lack of knowledge about proper tissue handling, tissue orientation, overlapping histological fi ndings, and lack of a standard algorithm based approach results in this low diagnostic yield. In this review article, we have tried to discuss these aspects and give a clear picture how to approach the ileal lesions. It would help the surgical pathologists in effectively interpreting the lesions and to identify the common pitfalls.

Efficacy of a commercial live attenuated Lawsonia intracellularis vaccine in a large scale field trial in Korea

PURPOSE: Porcine proliferative enteropathy (PPE) is known as one of the most important risk factors causing economic losses in swine industry worldwide. This study was conducted to evaluate the efficacy of a commercial oral attenuated Lawsonia intracellularis vaccine (Enterisol Ileitis) against PPE under a commercial pig farm condition in Korea. MATERIALS AND METHODS: Thirty two-day-old 672 piglets were randomly allocated into vaccinated and control groups. All piglets in the vaccinated group were inoculated with a commercial attenuated L. intracellularis vaccine as following the manufacturer's instruction. Body weights of all pigs in both groups were measured on the vaccination day and 6, 14, and 20 weeks post vaccination and an average daily weight gain (ADWG) was calculated. Health status was observed biweekly during the whole trial. RESULTS: The vaccinated group showed significantly higher body weight (p<0.05) and ADWG (p<0.05) than those of the control group. The vaccinated group had significantly reduced impairments in activity, growth, defecation frequency, and stool hardness (p<0.05). Additional health benefits and improved weight gain by the vaccination produced a 4.2:1 return of investment, and the higher gross margin was $4.80 per pig. CONCLUSION: Our finding suggests that the L. intracellularis vaccine program has effects on the substantial health and economic benefits in the Korean swine industry.

Ileitis tras ileostomía / Bleeding ileitis following ileostomy

Background: The incidence of ileitis following ileostomy is 5 percent. Material and Method: We report a 79 years old male with a sigmoid cancer presenting with an intestinal obstruction. Results: Patient required a subtotal colectomy, leaving a terminal ileostomy in the right lower flank. Three days after the intervention, the patient had a profuse bleeding through the ileostomy. An emergency endoscopy showed multiple bleeding ulcers in the ileostomy. The patient did not respond to medical treatment and required a new intervention, excising 20 cm of distal ileum and performing a new ileostomy. The pathological study of the excised segment showed multiple superficial ulcers with abundant inflammatory cells.

Introducción: La ileitis tras ileostomía es una entidad poco frecuente, pero que conlleva una importante morbilidad. Objetivo: Describir un caso de ileitis postileostomía sin respuesta al tratamiento médico y revisar la literatura sobre el tema. Material y Método: Presentamos el caso de un varón de 79 años con sangrado agudo por ileostoma tras colectomía subtotal. Resultados: Tras fracaso de la terapia médica fue necesario realizar resección de segmento de íleon terminal afecto. Conclusiones: Se debe pensar en ileitis postileostomía en caso de ileostomías muy productivas o ileorragias y comenzar tratamiento esteroideo temprano y realizar ileoscopia precoz. La cirugía se reserva para aquellos casos en los que no es eficaz el tratamiento médico.

Chronic Non-granulomatous Ulcerative Jejunoileitis Assessed by Wireless Capsule Endoscopy / 대한소화기학회지

Chronic non-granulomatous jejunoileitis is a rare disease characterized by malabsorption, abdominal pain, and diarrhea that causes shallow ulcers in the small bowel. The etiology of chronic non-granulomatous jejunolieitis remains unknown. A 69-year-old man complained of abdominal pain and lower extremity edema. A 99m-Tc albumin scan showed increased radioactivity at the left upper quadrant, suggesting protein-losing enteropathy. A small bowel follow-through did not disclose any lesions. Wireless capsule endoscopy revealed several small bowel ulcers and strictures. A jejunoileal segmentectomy with end-to-end anastomosis was performed, and the histologic examination revealed non-granulomatous ulcers with focal villous atrophy. Ruling out all other possible diagnoses, we diagnosed our patient with chronic non-granulomatous ulcerative jejunoileitis. Postoperatively, the patient's abdominal pain and lower extremity edema improved, and the serum albumin normalized. This is the first case of chronic non-granulomatous ulcerative jejunoileitis localized by wireless capsule endoscopy and treated successfully with segment resection.

A Case of Terminal Ileitis Caused by Ascaris lumbricoides / 대한소화기내시경학회지

The major causes of terminal ileitis are inflammatory bowel disease and NSAIDs but parasites such as Anisakis rarely induce ileitis. Ascaris lumbricoides, the most common intestinal helminth in Korea, may enter the pancreaticobiliary ducts and cause pancreatitis or cholangitis. However, no case of A. lumbricoides-associated terminal ileitis has been previously reported in Korea. We report a case of a 58-year-old woman who presented with epigastric discomfort and bloating, and was diagnosed with terminal ileitis due to A. lumbricoides detected during colonoscopy.
