Cholestatic Jaundice Secondary to Portal Hypertensive Biliopathy Regarding a Case of Cavernous Transformation of the Portal Vein

Portal hypertensive biliopathy comprises the anatomical and functional abnormalities of the intra- and extrahepatic biliary tract, cystic duct, and gallbladder in patients with portal hypertension. The compromise of the bile duct usually occurs in portal obstruction due to the cavernous transformation of the portal vein (CTPV). We present a case of a young patient with a recent history of portal hypertension and CTPV who presented with an episode of cholestatic hepatitis. Studies documented an image of nodular appearance with extrinsic compression of the distal bile duct compatible with a tumor-like cavernoma. Effective endoscopic treatment was performed using endoscopic retrograde cholangiopancreatography (ERCP), sphincterotomy, and biliary stenting.

La biliopatía hipertensiva portal comprende las anomalías anatómicas y funcionales del tracto biliar intra- y extrahepático, el conducto cístico y la vesícula biliar en pacientes con hipertensión portal. El compromiso de la vía biliar suele presentarse en obstrucción portal debido a transformación cavernomatosa de la porta. Presentamos un caso de un paciente joven, con historia reciente de hipertensión portal y cavernomatosis de la porta, que presentó un episodio de hepatitis colestásica y en estudios se le documentó una imagen de apariencia nodular con compresión extrínseca de la vía biliar distal compatible con tumor-like cavernoma. En este caso se realizó un tratamiento endoscópico efectivo mediante colangiopancreatografía retrógrada endoscópica (CPRE), esfinterotomía y stent biliar.

Características clínicas y tratamiento de la enfermedad de Crohn perianal fistulizante en Colombia: resultados de un registro multicéntrico / Clinical characteristics and treatment of perianal fistulising Crohn's disease in Colombia: Results of a multicentric registry

Introducción: La enfermedad de Crohn (EC) perianal fistulizante es un fenotipo de mal pronóstico. No existen estudios en nuestro medio. Nuestro objetivo es determinar las características clínicas, sociodemográficas y el tratamiento de la EC perianal fistulizante en un registro multicéntrico colombiano. Materiales y métodos: Se realizó un estudio observacional multicéntrico, retrospectivo, con recolección prospectiva de la información, en los principales centros de referencia de enfermedad inflamatoria intestinal (EII) del país. Las variables continuas se expresaron como medianas y rangos intercuartílicos. Las variables de resultado categóricas fueron comparados por la prueba de Chi-cuadrado. Resultados: Se documentaron 65 pacientes con EC perianal fistulizante, con una mediana de edad de aparición de fistula perianal de 31,0 años (rango: 24-42), predominando en hombres (61,5%; razón H:M: 1,4:1). Las fístulas perianales complejas fueron más frecuentes que las simples (75,35 vs. 24,6%). En cuanto al tratamiento médico, el 66,2% de los pacientes recibieron antibióticos, el 64,6% esteroides, el 78,5% terapia biológica, el 47,7% setones no cortantes y el 46,2% requirieron manejo quirúrgico, diferente a la colocación de setones. En solo el 29,2% se logró remisión completa de la fístula, y el 9,2% de los pacientes terminaron en colostomía definitiva. Los pacientes con EC con fístulas complejas recibieron más terapia biológica comparado con pacientes con EC y fístulas simples (84,8 vs. 56,3%; p: 0,038). Conclusiones: La EC perianal fistulizante es de mal pronóstico en nuestro medio, solo 3 de cada 10 pacientes logran la remisión completa a pesar del tratamiento. Un manejo multidisciplinario es fundamental para el manejo integral de esta difícil enfermedad.(AU)

Introduction: Perianal fistulizing Crohn's disease (CD) is a phenotype with a poor prognosis. There are no studies in our country. Our objective is to determine the clinical, sociodemographic and treatment characteristics of perianal fistulizing CD in a Colombian multicenter registry. Materials and methods: A retrospective, multicenter observational study was carried out, with prospective data collection, in the main reference centers for inflammatory Bowel disease (IBD) in the country. Continuous variables were expressed as medians and interquartile ranges. The categorical outcome variables were compared by the Chi-square test. Results: Sixty-five patients with perianal fistulizing CD were documented, with a median age of appearance of perianal fistula of 31.0 years (range: 24-42), predominantly in men (61.5%; H:M ratio: 1.4:1). Complex perianal fistulas were more frequent than simple ones (75.35 vs. 24.6%). Regarding medical treatment, 66.2% of the patients received antibiotics, 64.6% steroids, 78.5% biological therapy, 47.7% non-cutting setons, and 46.2% required surgical management, other than seton placement. Only 29.2% achieved complete remission of the fistula, and 9.2% of the patients ended up in a definitive colostomy. CD patients with complex fistulas received more biological therapy, compared to CD patients with simple fistulas (84.8 vs. 56.3%; P: 0.038). Conclusions: Perianal fistulizing CD has a poor prognosis in our setting, only 3 out of 10 patients achieve complete remission despite treatment. A multidisciplinary management is essential for the comprehensive management of this difficult pathology.(AU)

Endoscopic Ultrasound-Guided Transgastric Puncture and Drainage of an Adrenal Abscess in an Immunosuppressed Patient.

Adrenal gland infection is a clinical entity of great importance, but it is a largely unrecognized pathology. Immunosuppressed individuals are at a higher risk of presentation. Herein, we describe a young female patient, recently diagnosed with HIV, who presented with severe sepsis due to methicillin-resistant Staphylococcus aureus, associated with a left adrenal abscess. She was initially treated with antibiotics; however, due to the persistence of the systemic inflammatory response and bacteremia, endoscopic ultrasound-guided drainage was performed. This procedure was successful in resolving the clinical situation. Endoscopic ultrasound-guided adrenal gland drainage can be a safe, efficacious, and minimally invasive option for managing antibiotic-refractory adrenal abscesses in immunosuppressed patients.

Resumen Introducción: la anemia es la complicación más frecuente en enfermedad inflamatoria intestinal (EII). El objetivo de este estudio fue determinar la prevalencia, asociaciones y tratamiento de la anemia en EII en nuestro medio. Materiales y métodos: se analizaron de forma retrospectiva datos de pacientes adultos con EII del Hospital Pablo Tobón Uribe en Medellín, Colombia, que consultaron desde 2001 hasta febrero de 2019. Se emplearon frecuencias absolutas y relativas. Para comparar dos proporciones se utilizó la prueba de chi cuadrado de independencia y se estimó el Odds ratio (OR). Resultados: se documentaron 759 pacientes con EII, de los cuales 544 (71,6 %) presentaron colitis ulcerativa (CU); 200 (26,3 %), enfermedad de Crohn (EC), y 15, EII no clasificable (1,9 %). En total, 185 (24,4 %) pacientes con EII presentaron anemia, que es menos frecuente en CU que en EC (22,2 % frente a 32,5 %, respectivamente; OR: 0,684; IC: 0,456-0,96; p = 0,03). Los pacientes con CU extensa (54,1 %) tenían más anemia que aquellos con CU no extensa (46,3 %) (OR: 4,4; IC: 2,6-7,4; p = 0,001); lo mismo se observó al comparar la CU grave (66,1 %) con la no grave (32,3 %) (OR: 4,95; IC: 2,87-8,51; p = 0,000). En la EC, los pacientes con comportamiento no inflamatorio (B2, B3: 73,9 %) presentaron más anemia en comparación con aquellos con comportamiento inflamatorio (B1: 26,2 %) (OR: 0,35; IC: 0,18-0,67; p = 0,000). 44,3 % de los pacientes no recibió tratamiento, 19,5 % recibió hierro oral, 20,0 % recibió hierro intravenoso y 16,2 % fue transfundido. Conclusiones: la anemia es una complicación frecuente de la EII en nuestro medio (24,4 %). A pesar de las guías internacionales, el tratamiento es subóptimo en nuestro medio.

Abstract Introduction: Anemia is the most frequent complication of inflammatory bowel disease (IBD). This study aims to determine the prevalence, connection, and treatment of anemia in IBD in a local context. Materials and Methods: This retrospective study was conducted at The Pablo Tobon Uribe Hospital, in Medellín (Colombia) with adult patients who (were admitted) came for consultation from 2001, until February 2019. Absolut and relative frequencies were calculated. The Chi square test of independence was applied for comparing two proportions and the odds ratio (OR) was estimated. Results: A total of 759 IBD patients were enrolled, 544 (71.6%) with ulcerative colitis (UC); 200 (26.3%) Crohn's disease (CD), and 15 (1.9%) with non-classifiable IBD. In total, 185 (24,4 %) IBD patients had a diagnosis of anemia, that is less frequent in UC patients that in CD patients (22,2 % versus 32,5 %, respectively; OR: 0,684; CI: 0,456-0,96; p = 0,03). Extensive UC patients (54,1 %) had a more recurrent level of anemia than non-extensive UC (46,3 %) (OR: 4,4; CI: 2,6-7,4; p = 0,001); the same result was observed when severe UC (66,1 %) was compared with UC non-severe (32,3 %) (OR: 4,95; CI: 2,87-8,51; p = 0,000). In the analysis of CD, patients with a non-inflammatory response (B2, B3: 73,9 %) had a more recurrent level of anemia than patients with an inflammatory response (B1: 26,2 %) (OR: 0,35; CI: 0,18-0,67; p = 0,000). 44,3 % of the total number of patients received treatment, 19,5 % received oral iron, 20,0 % received intravenous iron, and 16,2 % received a blood transfusion. Conclusions: In our context, Anemia is a common complication in IBD cases (24,4 %). Despite the existence of international guidelines, the treatment in our context is not optimal.

La experiencia en un hospital de alta complejidad / The "Weekend Effect" in patients admitted to the Emergency Unit with non-variceal upper gastrointestinal bleeding. A high-complexity hospital experience

Resumen Introducción y objetivos: el "efecto fin de semana" se define como un incremento en la mortalidad en pacientes que ingresan a centros asistenciales durante el fin de semana o días festivos. Este estudio se realizó para evaluar el posible "efecto fin de semana" en pacientes con hemorragia digestiva superior (HDS) con base en una experiencia de 3 años en un hospital de alta complejidad en Latinoamérica. Materiales y métodos: estudio observacional descriptivo realizado entre 2016 y 2018. Se describieron las características demográficas, factores de riesgo, síntomas de ingreso, hallazgos endoscópicos y diferentes intervenciones médicas. Además, se compararon los tiempos de realización de endoscopia, estancia hospitalaria y mortalidad entre los pacientes admitidos durante el fin de semana frente a días entre semana. Resultados: el análisis incluyó 274 pacientes en fines de semana y festivos (39,1 %) frente a pacientes en días entre semana (60,9 %). La mediana de edad fue de 68,5 años (rango intercuartílico [RIC]: 53-79), el 56,6 % fueron hombres. Las manifestaciones más comunes fueron melenas y hematemesis. La úlcera péptica fue el diagnóstico endoscópico más común (48,7 %). Los tiempos de estancia hospitalaria (7,38 ± 8,7 frente a 7,38 ± 7,1; p = 0,234) y mortalidad (1,9 % frente a 4,2 %; p = 0,274) fueron similares en ambos grupos. Se realizó una mayor cantidad de endoscopias después de las 24 horas en pacientes ingresados el fin de semana (19,6 % frente a 9,6 %; p = 0,041). Conclusiones: en esta cohorte no se presentó el "efecto fin de semana", no se observan diferencias en relación con la estancia hospitalaria, ni con la mortalidad en pacientes ingresados por HDS.

Abstract Introduction and Objectives: The "Weekend Effect" refers to an increase in mortality of patients admitted to health care centers on weekends or holidays. This study was performed to assess the impact of weekend admissions in patients with upper gastrointestinal bleeding (UGIB) based on a three year-experience in a high-complexity hospital in Latin America. Materials and Methods: A descriptive observational study was performed between 2016 and 2018. Data on demographic characteristics, risk factors, symptoms, endoscopic findings, and medical treatment was described. Moreover, the time to perform an endoscopy, the length of hospital stay, and the mortality level among patients admitted on weekends were compared with the same factors during the week. Results: The analysis included 274 patients admitted during the weekend and holidays (39.1%) versus patients admitted during the week (60.9%). The median age was 68.5 years old (interquartile range [IQR]: 53-79), and 56.6% were men. The most common conditions were tarry stools and hematemesis. Peptic ulcer was the most common endoscopic diagnosis (48.7%). Similar results were found in the length of hospital stay (7,38 ± 8,7 versus 7,38 ± 7,1; p = 0,234) and mortality groups (1,9 % versus 4,2 %; p = 0,274). A higher number of endoscopies 24 hours after the patient was admitted was performed (19,6 % versus 9,6 %; p = 0,041). Conclusions: The "Weekend Effect" was not present in the analyzed group, and there are no significant differences related to the length of hospital stay or the mortality of patients diagnosed with UGIB.

Resumen Introducción: en pacientes con obstrucción biliar distal maligna en quienes la derivación biliar mediante colangiopancreatografía retrógrada endoscópica (CPRE) no sea factible o sea fallida, el drenaje biliar guiado por ultrasonido endoscópico mediante coledocoduodenostomía es una opción terapéutica viable, de la que se describen altas tasas de éxito técnico y clínico con una baja morbimortalidad. Adicionalmente, este método podría ser superior en la mejora de la calidad de vida en comparación con el manejo percutáneo o quirúrgico. Objetivo: describir la experiencia inicial con el drenaje biliar guiado por ultrasonido endoscópico en pacientes con obstrucción biliar maligna en un centro de referencia. Métodos: es una serie de casos retrospectiva de 6 pacientes con obstrucción biliar maligna a quienes se les realizó inicialmente una CPRE que fue fallida, por lo cual se procedió a realizar coledocoduodenostomía guiada por ultrasonografía endoscópica. Se describieron las tasas de éxito técnico, éxito clínico, eventos adversos, tasas de disfunción y tiempo de supervivencia de los pacientes. Resultados: se analizaron 6 casos, predominó el sexo femenino, con un promedio de edad de 71,8 ± 19,8 años; las indicaciones fueron adenocarcinoma de páncreas, tumor periampular y colangiocarcinoma distal. Se observó un éxito técnico en el 100 % de los casos y éxito clínico en 83,3 % de los casos. No se registraron eventos adversos graves. En el seguimiento de los casos se observó una supervivencia del 66,7 % a los 30 días. Conclusión: la coledocoduodenostomía es una alternativa terapéutica viable, segura y efectiva en pacientes con obstrucción biliar maligna en quienes la CPRE fue fallida, con una alta tasa de éxito técnico y clínico.

Abstract Introduction: Patients with malignant biliary distal obstruction who cannot be treated with endoscopic retrograde cholangiopancreatography (ERCP) or who had a failed ERCP, can find alternative treatment in endoscopic ultrasound-guided biliary drainage via choledochoduodenostomy. EUS-CDS performs with high rates of technical and clinical success and with low rates of morbimortality. Moreover, this method could have the potential to improve the patient's quality of life, compared with percutaneous or surgical means. Objective: This study aims to describe the initial experience with endoscopic ultrasound-guided biliary drainage in patients with malignant biliary distal obstruction in a reference center. Methods: Retrospective case review of six patients with malignant biliary obstruction and prior ERCP-placed and failed. Endoscopic ultrasound-guided biliary drainage via choledochoduodenostomy was performed as an alternative method. Technical and clinical success rates, adverse event rates, dysfunction rates, and patient survival time were described. Results: 6 cases were analyzed with a higher proportion of female patients, with a mean age of 71,8 ± 19,8 years. The symptoms were related to pancreas adenocarcinoma, periampullary tumor, and distal cholangiocarcinoma. The procedure was technically successful in 100% of cases and clinically successful in 83% of cases. Serious adverse events were nor reported. After 30 days, a survival rate of 66,7 % was observed. Conclusion: Choledochoduodenostomy is a viable, safe, and effective method in patients with malignant biliary obstruction who had a failed ERCP, and it has high rates of technical and clinical success.

[Ingestion of multiple magnets in pediatrics: endoscopic or surgical emergency?] / Ingestión de múltiples imanes en pediatría: ¿emergencia endoscópica o quirúrgica?

Ingestion of foreign bodies is common in the pediatric population. Most foreign bodies have a benign behavior and are usually eliminated without generating greater morbidity and mortality. In relation to the intake of magnets, its frequency has increased to the point that it currently represents a public health problem in the pediatric population. The ingestion of a single magnet does not generate any risk, but the ingestion of 2 or more of these, or even of magnets and metals in succession is considered an emergency since they can attract each other and can cause serious symptoms of intestinal obstruction, bleeding, fistulas, perforation and even intestinal necrosis. We present 2 pediatric patients, who ingested multiple magnets, in these cases we highlight the variety in the clinical presentation, as well as the complications presented in relation to a late diagnosis.

Caracterización y prevalencia de manifestaciones extraintestinales en una cohorte de pacientes con enfermedad inflamatoria intestinal en Medellín (Colombia) / Characterization and prevalence of extraintestinal manifestations in a cohort of patients with inflammatory intestinal disease in Medellin, Colombia

Introducción: Las manifestaciones extraintestinales (MEI) son frecuentes en pacientes con enfermedad inflamatoria intestinal (EII). Nuestro objetivo es caracterizar y determinar la prevalencia de MEI en nuestra cohorte de pacientes con EII. Pacientes y métodos: Se realizó un estudio retrospectivo en pacientes adultos con EII del Hospital Pablo Tobón Uribe en Medellín (Colombia). Se consideraron MEI articulares, colangitis esclerosante primaria (CEP), oftalmológicas y dermatológicas. Se emplearon frecuencias absolutas y relativas. Para comparar 2proporciones se utilizó la prueba χ2 de independencia y se estimó el odds ratio (OR). Resultados: Nuestro registro cuenta con 759 pacientes con EII, 544 presentaban CU (71,6%), 200 EC (26,3%) y 15 EII no clasificable (1,9%). Del total, 177 pacientes con EII (23,3%) presentaron MEI, 123 de 544 (22,6%) con CU y 53 de 200 (26,5%) con EC (OR: 0,81; IC 95%: 0,55-1,17; p=0,31). En cuanto al tipo de MEI, las articulares fueron las más frecuentes (13,5%), más en EC que en CU (20,0 vs. 11,3%; OR 1,94; IC 95%: 1,25-3,00; p=0,0037). Los pacientes con EII y MEI utilizaron más anticuerpos contra el factor de necrosis tumoral (anti-TNF) que aquellos sin MEI (43,5 vs. 18,5%; OR 3,38; IC 95%: 2,31-4,90; p=0,0001). Conclusiones: La prevalencia de MEI en nuestra cohorte es alta (23,3%) y el tipo más frecuente es la articular. Los anti-TNF son más utilizados cuando coexisten EII y MEI. Nuestro estudio aporta información valiosa sobre la asociación de MEI y EII en Latinoamérica.(AU)

Introduction: Extraintestinal manifestations (EIMs) are frequent in patients with inflammatory bowel disease (IBD). Our objective is to characterize and determine the prevalence of MEIs in our cohort of patients with IBD. Patients and methods: A retrospective study was carried out in adult patients with IBD at the Pablo Tobón Uribe Hospital in Medellín. Colombia. Articular MEIs, primary sclerosing cholangitis (PSC), both ophthalmological and dermatological, were considered. Absolute and relative frequencies were used. The Chi square test of independence was used to compare 2proportions and the odds ratio (OR) was estimated. Results: Our registry has 759 patients with IBD, 544 present UC (71.6%), 200 CD (26.3%) and 15 unclassifiable IBD (1.9%); 177 patients with IBD (23.3%) presented EIMs, 123 of 544 (22.6%) with UC and 53 of 200 (26.5%) with CD (OR: 0.81, 95% CI: 0.55-1.17, P=0.31). Regarding the type of EIMs, the articular ones were the most frequent (13.5%), more in CD than in UC (20.0 vs. 11.3%, OR 1.94, 95% CI: 1.25-3.00, P=0.0037). Patients with IBD and EIMs used more antibodies against tumor necrosis factor (anti-TNFs), compared to those without EIMs (43.5 vs. 18.5%, OR 3.38, 95% CI: 2.31-4.90, P=0.0001). Conclusions: The prevalence of EIMs in our cohort is high (23.3%) and the most frequent type is joint. Anti-TNFs are most used when IBD and EIMs coexist. Our study provides valuable information on the association of EIMs and IBD in Latin America.(AU)

Rendimiento diagnóstico de las punciones de lesiones biliopancreáticas guiadas por ultrasonido endoscópico con patólogo en sala / Diagnostic performance of endoscopic ultrasound-guided fine needle aspiration of pancreatobiliary lesions with rapid on-site evaluation

Resumen Introducción y objetivos: El ultrasonido endoscópico con punción-aspiración con aguja fina (USE-PAAF) en lesiones neoplásicas biliopancreáticas suele tener un rendimiento alto, que depende de características de la lesión; aspectos técnicos de la USE-PAAF y la experiencia del endoscopista. De los factores menos estudiados es la presencia de patólogo en sala. Se plantea la realización de USE-PAAF con patólogo en sala para disminuir el número de pases, la tasa de muestras inadecuadas y la necesidad de repetir el procedimiento. Material y métodos: Estudio observacional, retrospectivo, con recolección prospectiva de enero de 2018 a junio de 2019, en pacientes adultos sometidos a USE-PAAF. Las muestras obtenidas fueron extendidas y evaluadas en salas de endoscopia por médico patólogo con coloración Diff-Quick y cuando se obtenía una muestra suficiente se enviaba en frasco con formol para bloque celular o biopsias. Resultados: Se realizaron 48 USE-PAAF biliopancreáticas en individuos con una edad mediana de 64 años. Las indicaciones más frecuentes fueron punciones por masa o pseudomasa pancreática (71 % de casos); Se diagnosticaron 35 malignidades (77 % correspondientes a adenocarcinoma, y 14 % a tumores neuroendocrinos). La mediana de tamaño de lesiones fue de 28 mm; el número de pases promedio fue de 3. Se obtuvieron resultados diagnósticos en 89 % frente a 11 % de falsos negativos. Se presentó 1 complicación menor (2,1 %), que fue dolor abdominal. Conclusiones: La USE-PAAF con patólogo en sala tiene alto rendimiento diagnóstico, con escasos resultados falsos negativos. Se requiere una mediana de pases menor, que podría minimizar los riesgos del procedimiento y la necesidad de repetir la prueba.

Abstract Introduction: Endoscopic ultrasound with fine-needle aspiration (EUS-FNA) of pancreatobiliary neoplastic lesions usually has a high performance that depends on the characteristics of the lesion, technical aspects, and expertise of the endoscopist. One of the least studied factors is rapid on-site evaluation with a pathologist in the room. Objective: To perform EUS-FNA with a pathologist in the endoscopy room to reduce the number of passes, the rate of inadequate samples and the need to repeat the procedure. Material and methods: Observational retrospective study with a prospective data collection approach from January 2018 to June 2019 of adult patients undergoing EUS-FNA. The samples obtained were spread and evaluated in endoscopy rooms by a pathologist with Diff-Quick stain, and when a sufficient sample was obtained, it was sent in a vial with formalin for cell block and/or biopsy. Results: 48 pancreatobiliary EUS-FNA were performed in individuals with a median age of 64 years. The most frequent indication was aspiration due to pancreatic mass (71%); 35 malignancies were diagnosed (77% were adenocarcinomas and 14% were neuroendocrine tumors). The median size of the lesions was 28mm, and the average number of passes was 3. Diagnostic results were obtained in 89% vs. 11% of false negatives. There was 1 minor complication (2.1%), which was abdominal pain. Conclusions: EUS-FNA with an in-room pathologist has a high diagnostic performance, with few false negative results. Also, a lower median number of passes is required, minimizing the risks of the procedure and the need for repeating it.

Introduction: The small bowel capsule endoscopy (SBCE) has revolutionised the study of small bowel diseases. The objective of this study is to determine the indications, findings and diagnostic yield of SBCE in a national registry. Patients and methods: An observational, analytical cross-sectional study was carried out, analysing the SBCE records at seven centres in the country, where different variables were collected. Results: 1,883 SBCEs were evaluated. The average age was 55.4 years (5.6-94.2). The most frequent indications were suspicion of small bowel bleeding (SBB) (64.4%), study of Crohn's disease (15.2%) and chronic diarrhoea (11.2%). 54.3% were prepared with laxatives. The most frequent lesions found were erosions/ulcers (31.6%), angioectasias (25.7%) and parasitosis (2.7%). The diagnostic yield (P1+P2, Saurin classification) of SBCE in SBB was 60.6%, being higher in overt SBB (66.0%) compared to occult SBB (56.0%) (P=.003). The studies with better preparation showed higher detection of lesions (93.8% vs. 89.4%) (OR=1.8, CI: 95%: 1.2-2.6; P=.004). The SBCE complication rate was 3.1%, with complete SB visualisation at 96.6% and SB retention rate of 0.7%. 81.5% of SBCEs were performed on an outpatient basis, and presented a greater complete SB visualisation than hospital ones (97.1% vs. 94.3%) (OR=2.1, CI: 95%, 1.2-3.5; P=.008). Conclusions: The indications, findings and diagnostic performance of SBCEs in Colombia are similar to those reported in the literature, with a high percentage of complete studies and a low rate of complications.(AU)

Enfermedad de Crohn con compromiso extenso y manifestaciones extradigestivas inusuales: a propósito de un caso / Crohn's disease with extensive involvement and rare extraintestinal manifestations: A case report

Resumen La enfermedad de Crohn (EC) es considerada una entidad inmunológicamente mediada que compromete el tracto digestivo. Su compromiso suele ser transmural y puede afectar cualquier parte del tubo digestivo, desde la cavidad oral hasta el ano. Aunque se sabe que su extensión es variable, es poco habitual ver un compromiso extenso y multiorgánico. Se presenta el caso de un paciente joven, quien debutó con síntomas pulmonares asociados con la EC y años más tarde se presentaron los síntomas digestivos y de la vía biliar. El tratamiento se basó en la terapia con anticuerpos contra el factor de necrosis tumoral alfa (TNF-α), con lo cual se obtuvo una respuesta clínica satisfactoria. La relevancia clínica de este caso es la forma de presentación clínica tan florida, tanto por el compromiso gastrointestinal extenso como por las manifestaciones extradigestivas tan infrecuentes.

Abstract Crohn's disease (CD) is considered an immunologically mediated entity that involves the digestive tract. It is characterized by transmural inflammation and can affect any part of the digestive tract, from the oral cavity to the anus. Although it is recognized that its severity varies, extensive and multiple organ failure is unusual. We present the case of a young patient, who initially presented with pulmonary symptoms associated with CD. Years later, digestive and bile duct symptoms appeared. Treatment was based on anti-tumor necrosis factor-alpha antibody therapy, resulting in a satisfactory clinical response. The clinical relevance of this case is its full-blown presentation, which includes extensive gastrointestinal involvement and rare extraintestinal manifestations.

Ingestión de múltiples imanes en pediatría: ¿emergencia endoscópica o quirúrgica?

La ingesta de cuerpos extraños es común en población pediátrica. La mayoría de cuerpos extraños tienen un comportamiento benigno y suelen ser eliminados sin generar mayor morbimortalidad. En relación a la ingesta de imanes, se ha incrementado su frecuencia, a tal punto que en la actualidad representa un problema de salud pública en población pediátrica. La ingesta de un solo imán no genera ningún riesgo, pero la ingestión de 2 o más de estos, o incluso de imanes y metales de forma sucesiva se considera una emergencia ya que estos pueden atraerse entre sí pudiendo provocar cuadros graves de obstrucción intestinal, sangrado, fístulas, perforación e incluso necrosis intestinal. Presentamos 2 pacientes en edad pediátrica, que ingirieron múltiples imanes, en estos casos resaltamos la variedad en la presentación clínica, así como las complicaciones presentadas en relación a un diagnóstico tardío.

Ingestion of foreign bodies is common in the pediatric population. Most foreign bodies have a benign behavior and are usually eliminated without generating greater morbidity and mortality. In relation to the intake of magnets, its frequency has increased to the point that it currently represents a public health problem in the pediatric population. The ingestion of a single magnet does not generate any risk, but the ingestion of 2 or more of these, or even of magnets and metals in succession is considered an emergency since they can attract each other and can cause serious symptoms of intestinal obstruction, bleeding, fistulas, perforation and even intestinal necrosis. We present 2 pediatric patients, who ingested multiple magnets, in these cases we highlight the variety in the clinical presentation, as well as the complications presented in relation to a late diagnosis.

Insulinoma pancreático sintomático: tratamiento ablativo mediante etanolización guiado por ultrasonido endoscópico / No disponible

INTRODUCCIÓN: el insulinoma pancreático esporádico es un tumor con frecuencia benigno, generalmente solitario y menor de 20 mm. Cuando es funcionante, los pacientes experimentan síntomas relacionados con la producción excesiva de insulina. El diagnóstico es clínico, con confirmación bioquímica y radiológica. El tratamiento suele ser quirúrgico, pero en la actualidad se está desarrollando la ablación guiada por ultrasonido endoscópico. MATERIAL Y MÉTODOS: realizamos una serie de casos prospectiva de pacientes con insulinoma pancreático con síntomas de hipoglicemia severa, a quienes se les ofreció el tratamiento ablativo con etanol al 96 % guiado por ultrasonido endoscópico como tratamiento alternativo a la cirugía. RESULTADOS: el éxito técnico y clínico se consiguió en el 100 % de los casos. No se presentaron complicaciones asociados al procedimiento. CONCLUSIÓN: el tratamiento del insulinoma sintomático mediante ablación por etanolización guiada por ultrasonido endoscópico podría ser una alternativa segura y eficaz a la cirugía en pacientes no candidatos o que rechacen la intervención quirúrgica

Characterization and prevalence of extraintestinal manifestations in a cohort of patients with inflammatory intestinal disease in Medellin, Colombia. / Caracterización y prevalencia de manifestaciones extraintestinales en una cohorte de pacientes con enfermedad inflamatoria intestinal en Medellín (Colombia).

INTRODUCTION: Extraintestinal manifestations (EIMs) are frequent in patients with inflammatory bowel disease (IBD). Our objective is to characterize and determine the prevalence of MEIs in our cohort of patients with IBD. PATIENTS AND METHODS: A retrospective study was carried out in adult patients with IBD at the Pablo Tobón Uribe Hospital in Medellín. Colombia. Articular MEIs, primary sclerosing cholangitis (PSC), both ophthalmological and dermatological, were considered. Absolute and relative frequencies were used. The Chi square test of independence was used to compare 2proportions and the odds ratio (OR) was estimated. RESULTS: Our registry has 759 patients with IBD, 544 present UC (71.6%), 200 CD (26.3%) and 15 unclassifiable IBD (1.9%); 177 patients with IBD (23.3%) presented EIMs, 123 of 544 (22.6%) with UC and 53 of 200 (26.5%) with CD (OR: 0.81, 95% CI: 0.55-1.17, P=0.31). Regarding the type of EIMs, the articular ones were the most frequent (13.5%), more in CD than in UC (20.0 vs. 11.3%, OR 1.94, 95% CI: 1.25-3.00, P=0.0037). Patients with IBD and EIMs used more antibodies against tumor necrosis factor (anti-TNFs), compared to those without EIMs (43.5 vs. 18.5%, OR 3.38, 95% CI: 2.31-4.90, P=0.0001). CONCLUSIONS: The prevalence of EIMs in our cohort is high (23.3%) and the most frequent type is joint. Anti-TNFs are most used when IBD and EIMs coexist. Our study provides valuable information on the association of EIMs and IBD in Latin America.

Obliteration of gastric varices guided by eco-endoscopy with coils insertion coated with expandable hydrogel polymers.

INTRODUCTION: gastric varices hemorrhage is a severe complication of portal hypertension, with high mortality rates and few management alternatives, especially when there is a contraindication to transjugular intrahepatic portosystemic shunts (TIPS). The usual therapeutic options are the injection of cyanoacrylate, the insertion of coils or both. Hydrocoils are special coils coated with different types of expandable hydrogel polymers conventionally used in neurovascular interventionism. They allow rapid occlusion of vessel, forming a mesh that favors the local formation of thrombus and the development of a neointima on the gel cover. We consider the use of endoscopic ultrasound (EUS) guided hydrocoil insertion in gastric varices, without using cyanoacrylate. OBJECTIVE: this study aimed to evaluate the safety and effectivity of the application of EUS-guided hydrocoils in patients with gastric varices hemorrhage with TIPS contraindication. MATERIAL AND METHODS: this was a retrospective case series of four patients with TIPS contraindication after interventional radiologist evaluation. Linear echoendoscopes, fluoroscopy, 19G needles and hydrocoils (Azur®, Terumo) and Progreat® 3 Fr microcatheters were used. An interventional radiologist expert advised the procedures and endoscopic ultrasound confirmed the varix obliteration. RESULTS: technical and clinical success occurred in all patients involved in this study. There were no adverse effects related to the procedure or endoscopic equipment damage. CONCLUSIONS: the application of EUS-guided hydrocoils can be a safe and effective method in the short term for gastric varices bleeding in patients who are not candidates for TIPS. Besides, a complete obliteration of the vascular lumen could occur and thus, dispense with the use of cyanoacrylate. Further studies are needed to corroborate these preliminary results.

Clinical utility of the small bowel capsule endoscopy in the study of small bowel diseases in Colombia: Results of a national registry. / Utilidad clínica de la videocápsula endoscópica en el estudio de patologías de intestino delgado en Colombia: resultados de un registro nacional.

INTRODUCTION: The small bowel capsule endoscopy (SBCE) has revolutionised the study of small bowel diseases. The objective of this study is to determine the indications, findings and diagnostic yield of SBCE in a national registry. PATIENTS AND METHODS: An observational, analytical cross-sectional study was carried out, analysing the SBCE records at seven centres in the country, where different variables were collected. RESULTS: 1,883 SBCEs were evaluated. The average age was 55.4 years (5.6-94.2). The most frequent indications were suspicion of small bowel bleeding (SBB) (64.4%), study of Crohn's disease (15.2%) and chronic diarrhoea (11.2%). 54.3% were prepared with laxatives. The most frequent lesions found were erosions/ulcers (31.6%), angioectasias (25.7%) and parasitosis (2.7%). The diagnostic yield (P1+P2, Saurin classification) of SBCE in SBB was 60.6%, being higher in overt SBB (66.0%) compared to occult SBB (56.0%) (P=.003). The studies with better preparation showed higher detection of lesions (93.8% vs. 89.4%) (OR=1.8, CI: 95%: 1.2-2.6; P=.004). The SBCE complication rate was 3.1%, with complete SB visualisation at 96.6% and SB retention rate of 0.7%. 81.5% of SBCEs were performed on an outpatient basis, and presented a greater complete SB visualisation than hospital ones (97.1% vs. 94.3%) (OR=2.1, CI: 95%, 1.2-3.5; P=.008). CONCLUSIONS: The indications, findings and diagnostic performance of SBCEs in Colombia are similar to those reported in the literature, with a high percentage of complete studies and a low rate of complications.

Endoscopic ultrasound-guided ethanol ablation for the management of a symptomatic pancreatic insulinoma.

INTRODUCTION: pancreatic insulinoma is a sporadic, usually benign, frequently solitary tumor that is smaller than 20 mm. When it is functioning, patients present with symptoms of hypoglycemia secondary to insulin hypersecretion. The diagnosis is clinical, with biochemical and radiological confirmation. Surgery is the management of choice, although endoscopic ultrasound-guided ablation is currently being developed. MATERIAL AND METHODS: we present a prospective case series of pancreatic insulinoma patients with symptoms of severe hypoglycemia, who were treated with endoscopic ultrasound-guided ethanol ablation as an alternative to surgical management. RESULTS: technical and clinical success was achieved in all cases and there were no complications associated with the procedure. CONCLUSION: the treatment of symptomatic insulinoma by endoscopic ultrasound-guided ethanol ablation could be a safe and effective alternative to surgical management in non-surgical patients or those who refuse surgery.
