Primary gastric melanoma is an exceptional tumour with less than 20 cases described in the literature, as its origin is not entirely clear as the presence of melanocytes in the stomach has not been demonstrated. Symptomatology is non-specific, which prevents its early detection, and it is diagnosed in late stages. We present the case of a patient who was admitted to our hospital for vomiting in coffee grounds with analytical and haemodynamic repercussions. Urgent gastroscopy revealed a gastric lesion suspicious for malignancy, which was histologically confirmed as gastric melanoma. The therapeutic approach to these tumours is complex and they have a very poor prognosis.

INTRODUCTION The primary goal of this study was to compare gastrointestinal symptom reduction in patients on bismuth-containing quadruple eradication therapy supplemented with Lactobacillus reuteri strains (DSM 17938 and ATCC PTA 6475) or placebo. MATERIALS AND METHODS This was randomized, double-blind, parallel-arm, placebo-controlled clinical trial. Patients received first-line an eradication regimen based on bismuth subcitrate potassium, metronidazole, tetracycline hydrochloride (three-in-one capsules), and omeprazole 40 mg twice a day for ten days, plus a probiotic or placebo tablet for 30 days. During follow-up gastrointestinal symptoms were assessed using an evaluation scale (GSRS), and adverse events were collected at 0, 14, 28, and 56 days. RESULTS A total of 80 patients were included from February 2018 to May 2019 at a single site. Eradication therapy was effective for 85% of patients, with no differences between treatment arms. In the group receiving the probiotic, abdominal pain decreased in 42% of patients, compared with 19% in the control group (OR: 0.27; CI, 0.13-0.58; p < 0.001), and abdominal distension decreased in 25% versus 17% in the control group (OR: 0.24; IC, 0.19-0.84; p < 0.001); Conclusions: Treatment with L. reuteri only reduced abdominal pain and distension. Further studies are needed to establish the role of probiotics as adjuvant therapy in H. pylori eradication.

[Introduction] patients with advanced chronic liver disease (CLD) may be at an increased risk of a severe course due to cirrhosis-associated immune dysfunction. The aim of this study was to determine the prevalence of CLD in COVID-19 patients and to analyze the course of the infection, compared with patients with non-liver disease., [Materials and methods] this was a retrospective single center study of all patients with a positive SARS-CoV-2 polymerase chain reaction (PCR) test from March 23rd to April 30th, 2020. Clinical and biochemical data of patients with and without CLD and COVID-19 were collected from the medical records., [Result] four hundred and forty-seven patients with a SARS-CoV-2 positive PCR were included, 6.3 % had CLD; 69.7 % of patients with CLD were male, with a median age of 65.5 years and active alcohol consumption and smoking; 75 % had non-advanced liver fibrosis and most had non-alcoholic fatty liver disease (NAFLD). The hospital admission rate (92.9 % vs 47.7 %, p < 0.001), concomitant comorbidities (diabetes 38.5 vs 16.5 %, p = 0.011; obesity 30.8 vs 8.5 %, p = 0.033; cancer 23.1 vs 5 %, p = 0.027; and chronic obstructive pulmonary disease (COPD) 19.2 vs 9 %, p = 0.009) and concomitant antibiotics treatment (19.3 vs 5 %, p = 0.018) were higher in patients with CLD than in those without CLD. In-patient hospital mortality rates were similar in both groups (30.8 vs 19.6 %, p = 0.289). The presence of CLD was not associated with mortality (OR = 1.06; 95 % CI = 0.35-3.18; p = 0.924). However, patients with CLD and COVID-19 who were male, obese or under concomitant antibiotic treatment had the highest risk of mortality according to the univariate analysis., [Conclusion] patients with CLD had a higher risk of hospital admission, with worse outcomes during the COVID-19 infection associated to other concomitant comorbidities and a suspicion of bacterial co-infection., Financial support statement: this study was partly supported by Plan Nacional de I+D+i 2013-2016 and Instituto de Salud Carlos III, Subdirección General de Redes y Centros de Investigación Cooperativa, Spanish Ministry of Science and Innovation, Spanish Network for Research in Infectious Diseases (REIPI RD16/0016/0001), co-financed by the European Development Regional Fund “A way to achieve Europe”, Operative Program Intelligence Growth 2014-2020.

Primary follicular lymphomas (FL) of the gastrointestinal (GI) tract are very rare and constitute < 4 % of all non-Hodgkin's lymphomas at this location. We report our experience with primary FL of the GI tract.

A new subcutaneous formulation of the infliximab biosimilar CT-P13 has recently been developed for the treatment of inflammatory bowel disease (IBD), providing response rates similar to intravenous treatment. In an effort to limit patient attendance at intravenous infusion centers and to maintain biological treatment during the COVID-19 pandemic, the use of this new formulation was requested. The objective of this observational, retrospective, and descriptive study was to assess CT-P13 efficacy and safety after switching from intravenous to subcutaneous formulation in patients with IBD receiving maintenance therapy. This article shows preliminary results after six months of follow-up.

The incidence of biliary stent migration is low, and most cases are asymptomatic, with elimination of the piece by the feces. We report the case of a patient with an ileal perforation secondary to a plastic biliary stent migration. Intestinal perforation due to stent migration is an extremely rare complication, being mostly located at duodenum. Patients with previous surgeries, diverticulosis or abdominal wall hernias have a higher risk of complications in case of prosthetic migration, that is the reason why they require special attention and follow-up.

We report the case of a 67-year-old male who was referred to our hospital due to severe abdominal pain and fever. His past medical history included a total gastrectomy surgery for stomach cancer. Abdominal examination showed intense pain on deep palpation in the epigastric region. Laboratory test revealed elevated C-reactive protein (235 mg/l) and amylase (1,789 U/l). Computerized tomography reported a pancreatic collection with the presence of air bubbles inside and areas of necrotic pancreatic parenchyma.

Introduccion: la endoscopia tiene un papel fundamental en el manejo de los pacientes con colitis ulcerosa (CU), ya que permite la visualizacion y evaluacion de la gravedad de la enfermedad. No obstante, dicha evaluacion no es siempre algo objetivo, por lo que se han desarrollado diferentes escalas que pretenden homogeneizar los hallazgos. Objetico: el objetivo del estudio fue evaluar la variabilidad interobservador entre el Indice de Mayo Endoscopico (IME) y el Indice de Severidad Endoscopica de la Colitis Ulcerosa (UCEIS), al analizar la gravedad de las lesiones endoscopicas en pacientes con CU. El objetivo secundario fue analizar si la preparacion catartica afectaba al grado de concordancia entre los endoscopistas. Material y metodos: se trata de un estudio observacional comparativo de una unica cohorte a la cual se realiza una colonoscopia bajo guia de practica clinica habitual a pacientes con CU y se estadifica segun el IME y el UCEIS por tres endoscopistas expertos. Para valorar el grado de correlacion interobservador se utilizaron el indice de Kappa para el IME y el coeficiente de correlacion intraclase para el UCEIS. Se incluyeron 67 pacientes, con edad media de 51 anos (DE ± 16,7) e indice de Mayo clinico medio de 3,07 (DE ± 2,54). Resultados: el indice de Kappa ponderado entre los endoscopistas A y B para el IME fue de 0,8; entre el A y el C, de 0,52; y entre el B y el C, de 0,49. Para el UCEIS, el coeficiente de correlacion intraclase fue del 0,922 entre los tres endoscopistas (IC 95 %: 0,832-0,959). Se encontro una mejor correlacion interobservador cuando la preparacion catartica era ≥ 8 segun la escala de Boston. Conclusion: existe, por tanto, una superior correlacion entre los diferentes endoscopistas para el UCEIS que para el IME, por lo que deberia ser considerado como el mejor indice a utilizar en la practica clinica. Una buena preparacion catartica es importante para mejorar la correlacion interobservador.

Introduction between 30 % and 40 % of patients treated with infliximab lose response during maintenance. Therapeutic drug monitoring could be used to optimize management in these situations. However, infliximab serum levels are not well defined. The aim of this study was to determine the cut-off range of infliximab serum levels in Crohn's disease patients in remission in the clinical practice. Methods an observational retrospective study was performed from 2016 to 2017. Patients were included with established Crohn's disease, who had been on a maintenance dose schedule of infliximab. Infliximab levels and antibodies to infliximab were measured at least twice in all patients, after induction and after six months of treatment. Clinical remission was defined as ≤ 4 using the Harvey-Bradshaw index. Cluster analysis was used to analyze the results. Results one hundred and five Crohn's disease patients were included in the study; 57.1 % were male with a mean age of 39 years (SD ± 12.9). The median (range) time of the disease was eleven years (7-15) and the median (range) time of follow-up was 32 months (22-38). Patients who achieved remission had infliximab serum levels between 4.26-8.26 ug/ml versus 0.06-1.43 ug/ml in patients who did not achieve remission after induction. Infliximab serum levels were 2.84-7.75 ug/ml and 0.05-2.69 ug/ml in patients who achieved remission versus those who did not achieve remission after six months of treatment. Overall, 4.26-8.26 ug/ml was found to be the best cut-off range for remission. Conclusions in our clinical practice, serum levels of infliximab in Crohn's disease patients should be higher than 4 ug/ml to achieve clinical remission.

several barriers remain in the hepatitis C care cascade, which need to be removed in order to eliminate chronic hepatitis C. These barriers include deficiencies in screening and confirmatory diagnosis as well as difficulties in accessing treatment.to identify factors associated with the non-referral of patients with positive hepatitis C virus (HCV) antibodies and to identify factors associated with loss of follow-up or non-attendance of these patients to specialist consultation after referral.observational and retrospective single-center-study, including all positive HCV serology tests performed between January 2013 and May 2018, in the Virgen Macarena health area (Seville, Spain) before implementing the one-step diagnosis. Non-referred patients and patients who were lost to follow-up after being referred were identified.a total of 54 (77.4 %) patients diagnosed in Primary Care (PC) and 54 (22.2 %) from hospital specialists were not referred (p0.001). Predictors for non-referral were: stay in prison/institutionalization (p = 0.04), suffering chronic obstructive pulmonary disease (COPD) (p = 0.07), a normal AST value (p = 0.034) or test requested by Primary Care physician (PCP) (p = 0.004). Patients referred from PC were more likely to be lost to follow-up than those referred from hospital specialists (p0.001). Predictors of follow-up loss included: opioid replacement therapy (p = 0.034), absence of high blood pressure (p = 0.039) and test requested by PCP (p = 0.049).a high percentage of patients with positive HCV serology were not referred or were lost to follow-up, mainly those belonging to high risk social groups or those with associated comorbidities. Patients with average values of transaminases or those diagnosed in PC were also less frequently referred.

Introduccion y objetivos: la pandemia por el SARS-COV2 ha obligado a un cambio sustancial en la atencion a los pacientes con patologias digestivas, en especial a los pacientes con enfermedad inflamatoria intestinal (EII), por estar tratados con farmacos inmunomoduladores. En este sentido, algunas guias nacionales e internacionales han indicado las normas a tener en cuenta. No obstante, pocos trabajos han evaluado como han afrontado los pacientes esta infeccion. Por ello, hemos realizado este estudio con el objetivo de conocer como ha afectado la pandemia por SARS-COV2 a nuestros pacientes con EII. Material y metodos: se realizo una encuesta on-line entre los 295 miembros de la Asociacion de Enfermos de Crohn y Colitis Ulcerosa (ACCU) que constaba de 19 preguntas. Resultados: participaron 168 pacientes de la ACCU, de los cuales un 58 % eran mujeres, el 63,7 % tenia una EC y el 53 % recibia tratamiento biologico. Un 5 % fueron infectados por el SARS-CoV2, todos ellos varones. La principal preocupacion de los pacientes era el miedo a adquirir la infeccion (80,9 %). Mas del 90 % continuo con su tratamiento inmunosupresor y biologico. La mitad de los pacientes teletrabajaron durante el periodo de pandemia. Conclusiones: la perspectiva de los pacientes es fundamental para conseguir un adecuado manejo y evolucion de la enfermedad. Son necesarios mas trabajos que evaluen el impacto que situaciones excepcionales como la pandemia COVID-19 puede ocasionar sobre los pacientes con EII para mejorar la adherencia y el control de la enfermedad.

Splenosis is an uncommon pathology whose diagnosis requires a high index of suspicion. In most cases they are incidental findings, so their suspicion is essential to carry out a non-invasive diagnosis. We present a case of intraabadominal splenosis and perform a brief review of the literature.

Background: vedolizumab is an α4β7 integrin antagonist. The aim of this study was to evaluate the clinical response and remission rates with vedolizumab. Methods: this was a retrospective study of inflammatory bowel disease (IBD) patients who received vedolizumab between 2016 and 2019. Response and remission rates were analyzed at three, six, 12, 18 and 24 months after induction. Results: fifty-five patients were included. Clinical remission rates in CD and UC at three, six, 12, 18 and 24 months were 19.35 %, 26.67 %, 30.43 %, 30 %, 38.89 % and 29.17 %, 26.09 %, 19.05 %, 26.67 % and 20 %, respectively. Conclusions: vedolizumab is effective for induction and maintenance of clinical remission, both in Crohn’s disease and ulcerative colitis.

We present a case of arcuate ligament syndrome diagnosed in a 23-year-old patient with epigastric pain, vomiting and weight loss, using Doppler ultrasound and CT-angiography, treated by surgical resection of the ligament with complete resolution of symptoms. In addition, incidentally the patient was diagnosed with a nutcracker syndrome, without clinical repercussions.

BACKGROUND Infliximab original has changed the natural history of inflammatory bowel diseases (IBD) over the past two decades. However, the recent expiration of its patent has allowed the entry of the first Infliximab biosimilar into the European and Spanish markets. Currently switching drugs data in IBD are limited. AIM To compare the efficacy of infliximab biosimilar, CT-P13, against infliximab original, analyzing the loss of response of both at the 12 mo follow-up in patients with IBD. METHODS An observational study of two cohorts has been conducted. One retrospective cohort that included patients with IBD treated with Infliximab original, and a prospective cohort of patients who were switching from infliximab original to infliximab biosimilar (CT-P13). We had analyzed the overall efficacy and loss of efficacy in patients in remission at the end of one year after treatment with the original drug compared to the results of the year of treatment with the biosimilar. RESULTS 98 patients (CD 67, CU 31) were included in both cohorts. The overall efficacy for infliximab original per year of treatment was 71% vs 68.2% for infliximab biosimilar (P = 0.80). The loss of overall efficacy at 12 mo for infliximab original was 6.6% vs 14.5% for infliximab biosimilar (P = 0.806). The loss of efficacy in patients who were in basal remission was 16.3% for infliximab original vs 27.1% for infliximab biosimilar. Adverse events were 9.2% for infliximab original vs 11.2% for infliximab biosimilar. CONCLUSION The overall efficacy and loss of treatment response with infliximab biosimilar (CT-P13) is similar to that observed with infliximab original in patients who were switching at the 12 mo follow-up. There is no difference in the rate of adverse events.

espanolObjetivo: evaluar la eficacia y seguridad de la terapia cuadruple con omeprazol mas “una capsula tres-en-uno” que contiene subcitrato de bismuto, metronidazol y tetraciclina (BMTO) en pacientes, naive y fracasos previos, diagnosticados de infeccion con Helicobacter pylori, en el area de Sevilla, en condiciones de practica clinica habitual. Metodos: estudio prospectivo realizado en pacientes consecutivos con infeccion confirmada por Helicobacter pylori y sintomas gastrointestinales del tracto superior. Los pacientes fueron tratados, tras firmar el consentimiento, con Pylera® (capsula tres-en-uno que contiene 140 mg de subcitrato de bismuto, 125 mg de metronidazol y 125 mg de tetraciclina) cuatro veces al dia, mas omeprazol (20 o 40 mg) dos veces al dia, durante diez dias. La erradicacion fue establecida mediante un test de urea en aliento negativo realizado, al menos, 28 dias despues de finalizar el tratamiento. Resultados: un total de 58 pacientes fueron incluidos consecutivamente, dos de ellos fueron retirados del estudio por vomitos al tercer y quinto dia, respectivamente. Diecisiete (29,3%) pacientes tenian historia previa de tratamiento de su infeccion por Helicobacter pylori. En la poblacion por intencion de tratar las tasas de erradicacion fueron del 97,6% (40/41) y del 82,4% (14/17) en los pacientes tratados con Pylera® como primera linea o como terapia de rescate, respectivamente. Veintiocho pacientes (48%) presentaron, al menos, un acontecimiento adverso, la mayoria (86%) leves. Conclusion: diez dias de tratamiento con BMTO es una estrategia eficaz y segura en pacientes con infeccion confirmada por Helicobacter pylori. EnglishObjective: To evaluate the efficacy and safety of a quadruple regimen (BMTO) of the “3-in-1 capsule” (containing bismuth subcitrate potassium, metronidazole and tetracycline) plus omeprazole in naive and previously treated patients diagnosed with Helicobacter pylori (H. pylori) infection in the clinical setting in Seville (Spain). Methods: This is a prospective study carried out on consecutive patients with a confirmed H. pylori infection and upper gastrointestinal symptoms. After providing their informed consent, the patients were treated for ten days with a 3-in-1 capsule containing bismuth subcitrate potassium (140 mg), metronidazole (125 mg) and tetracycline (125 mg: Pylera®), three capsules four times daily, plus omeprazole (20 or 40 mg) twice daily. Eradication of infection was determined by a negative urea breath test at least 28 days after the end of treatment. Results: A total of 58 consecutive patients were enrolled into this study, two of whom withdrew early due to vomiting on days three and five, respectively. In this cohort, 17 patients (29.3%) had a prior history of medication to treat H. pylori. In the intent-to-treat population, eradication was achieved in 97.6% (40/41) and 82.4% (14/17) of cases in patients treated with BMTO as a first-line or rescue therapy, respectively. At least one adverse event was reported by 28 (48%) patients, mostly mild effects (86%). Conclusion: A ten day treatment with BMTO is an effective and safe strategy to combat confirmed H. pylori infection in patients

Background: The incidence of inflammatory bowel disease is increasing in Europe and in Spain. However, there is no recent data from Southern Spain. Objectives: To determine the evolution of the hospital incidence of inflammatory bowel disease in Southern Spain. Material and methods: A retrospective study was performed in two hospitals in Southern Spain. Data was collected from inflammatory bowel disease patients, divided into two periods (1995-2000 and 2001-2014) and compared. The reference population from both areas was 1,011,555 inhabitants. Results: A total of 430 patients were registered during the first period (1995-2000); 50% (215) had Crohn’s disease that resulted in a cumulative incidence rate of 7.08 cases/100,000 inhabitants per year. The overall inflammatory bowel disease incidence was 3.54 cases/100,000 inhabitants per year. During the second period (2001-2014), 2,089 patients were collected; 51.7% had ulcerative colitis (1,081). The rate of cumulative incidence of inflammatory bowel disease was 14.7 cases/100,000 inhabitants per year (7.6 cases of ulcerative colitis/100,000 inhabitants/year and 7.1 cases of Crohn´s disease/100,000 inhabitants/year). Conclusions: The incidence of inflammatory bowel disease in Southern Spain has doubled in the last decade and is similar to that of the rest of the country and Europe.

espanolIntroduccion: el esofago de Barrett (EB) es una enfermedad adquirida definida por la presencia de metaplasia intestinal en el esofago distal. Su prevalencia se ha incrementado de forma alarmante en los ultimos anos. Objetivos: los objetivos primarios del presente trabajo fueron analizar el comportamiento del EB y del adenocarcinoma esofagico (ACE) en un area sanitaria espanola durante el seguimiento del periodo del estudio. Metodos: se analizaron caracteristicas sociodemograficas y el consumo de alcohol y tabaco. Tambien se valoro el comportamiento histologico asi como las causas de defuncion en cada uno de los grupos. Resultados: se incluyeron 430 pacientes, 338 con EB y 92 con ACE. La tasa de incidencia paso de 2,25 y 1,25 por 100.000 habitantes en 1996 a 6,5 y 4,75 en 2011, en EB y ACE, respectivamente. Hubo mas varones, mayor edad e ingesta etilica en el grupo adenocarcinoma respecto al grupo de Barrett. La supervivencia del ACE fue de 23 meses. Las principales causas de muerte en los pacientes con Barrett fueron el cancer no esofagico y la enfermedad cardiovascular. Conclusiones: existe una mayor incidencia y prevalencia tanto del EB como del ACE en los ultimos anos. Como factores de riesgo encontramos el sexo masculino, mayor edad y consumo de alcohol. El EB largo (> 3 cm) esta implicado en la progresion de la displasia. El diagnostico de ACE se hace, la mayor parte de las veces, con el debut de la enfermedad neoplasica y, en el menor de los casos, sobre un EB previo. La enfermedad cardiovascular y neoplasica no esofagica han sido las principales causas de mortalidad en los pacientes con EB. EnglishBackground: Barrett’s esophagus (BE) is an acquired disease defined by the presence of intestinal metaplasia with goblet cells in the distal esophagus. The prevalence of BE has increased dramatically over the last years. Aims: The primary aims of the study were to analyze the characteristics of BE and esophageal adenocarcinoma (EAC) in a Spanish health district during a follow-up period. Methodology: Sociodemographic factors, alcohol consumption and cigarette smoking were analyzed. We also studied the histological behavior and cause of death in each group. Results: In the present study 430 patients were included, 338 with BE and 92 with EAC. Incidence rates have risen from 2.25 and 1.25 per 100,000 inhabitants in 1996 to 6.5 and 4.75 per 100,000 in 2011, respectively. In the EAC group, male gender, age and alcohol consumption were higher in comparison to the BE group, and the overall survival was 23 months. In the BE group, the main causes of death were non-esophageal cancer and cardiovascular disease. Conclusions: The incidence and prevalence rates of AEC and BE have risen over the past years. Risk factors for these conditions were male gender, age and alcohol consumption. Long BE (> 3 cm) is involved in dysplasia progression. AEC diagnosis mainly occurs after neoplasia is detected and, in a few cases, due to a previous BE. Cardiovascular diseases and non-esophageal cancers have been found to be the main cause of death in BE patients.

Introducción: El objetivo de la presente investigación ha sido comparar mediante un ensayo clínico la efectividad de una Psicoterapia Breve con el tratamiento habitual de los Trastornos Mentales Comunes en los Centros de Salud Mental (CSM) de Asturias. La introducción general a este estudio se ha descrito por Fernández-Méndez y cols. (2010) y se remite a los lectores a ese artículo para más detalles respecto al fundamento, diseño, tratamientos y procedimientos de la investigación. Sujetos y método: Se seleccionaron al azar 216 personas mayores de 14 años que consultaban por primera vez en seis CSM y que fueron diagnosticadas de trastornos depresivos, de ansiedad y/o de adaptación. Ciento cuarenta y una cumplían los criterios de inclusión y aceptaron participar en la investigación, siendo asignadas al azar a dos grupos: Psicoterapia breve integradora-ecléctica (n = 76) o Tratamiento habitual en los CSM (n = 65). Se han comparado sus resultados a los 6, 12, 24 y 36 meses en diversos índices de mejoría clínica, funcionamiento psicosocial e indicadores sanitarios indirectos. Los datos se han obtenido del Registro de Casos Psiquiátricos, de la Historia Clínica y del propio paciente. Se han usado los siguientes instrumentos: Impresión Clínica Global (ICG, Guy, 1976), Inventario de Discapacidad de Sheehan (SDI, Sheehan, 1996) y Cuestionario de Satisfacción (Moré y Muñoz, 2000). Resultados: El programa de Psicoterapia breve ha sido más efectivo que el tratamiento habitual: Obtiene una mayor tasa de altas y los sujetos muestranmayores mejorías en estado clínico y discapacidad y mayor satisfacción. Estas diferencias se dan tanto a los seis meses como al año y a los dos años de iniciarse los tratamientos. Además, aunque el número medio de sesiones es igual en ambos grupos (en torno a seis), el tratamiento experimental duró mucho menos tiempo. Conclusiones: La Psicoterapia ha resultado ser un tratamiento viable y efectivo para la mayoría de los casos que consultan en los CSM.

El desarrollo reciente de la capsula endoscopica permite el estudio endoscopico de todo el intestino delgado de forma segura y no invasiva. La hemorragia digestiva de origen desconocido supone la principal indicacion de la tecnica (sensibilidad del 89%; especificidad del 95%), obteniendose un rendimiento diagnostico muy elevado en pacientes con hemorragia activa (92,3%), que desciende claramente en los casos de hemorragia previa no activa (12,9%). La capsuloendoscopia ha sido tambien propuesta en pacientes con sospecha clinica y analitica de enfermedad de Crohn de intestino delgado no confirmada mediante tecnicas convencionales, respecto a la cual se han publicado algunos estudios con resultados prometedores. Finalmente, el papel que la capsula puede desempenar en el diagnostico de pacientes con enfermedad celiaca, tumores intestinales, sindromes de poliposis gastrointestinal, dolor abdominal no filiado, pacientes pediatricos o en la afeccion intestinal de enfermedades sistemicas debera ser establecido por estudios amplios bien disenados.

Introduction: Capsule endoscopy (CE) has become a first-line tool for small bowel (SB) examination. However, adverse events (AEs), such as CE retention or aspiration, may occur. The aims of this study were to evaluate incidence, clinical outcomes and therapeutic approaches of CE-related AEs in the largest series published to date. Methods: Data from 5428 procedures performed at 12 institutions between August 2001 and January 2012 were retrospectively analyzed. Baseline patient characteristics; procedure; type, localization and symptoms before/after AEs; previous patency tests performed; therapeutic management and patient´s outcome were recorded. Results: The overall incidence of CE-related AEs was 1.9%: 2.0% for SB, 0.9% for esophageal and 0.5% for colon CE. The incidence of capsule retention was significantly higher than capsule aspiration (1.87% vs. 0.003%; p < 0.05), in patients suffering from inflammatory bowel disease (IBD) than in obscure GI bleeding (OGIB) (3.3% vs. 1.5%; p < 0.05) and in patients with the combination of nausea/vomiting, abdominal pain and distension. The SB was the most frequent localization of retention (88.2%). The use of patency tests -except for Patency© capsule- before CE was not a good predictor for AEs. Most of the patients with AEs developed no or mild symptoms (97%) and were managed by non-surgical methods (64.4%). Conclusions: CE-related AEs are uncommon and difficult to predict by imagiological examinations. SB retention, that is usually asymptomatic, is the most frequent AE. In absence of symptoms, non-surgical management of CE-related AEs is recommended.

Capsule endoscopy is nowadays the diagnostic technique of choice in the study of small bowel pathologies, allowing the non-invasive study of the entire mucosa. This has led, together with new technical advances, to the creation of two new models (PillCam ESO and PillCam Colon) for the study of esophageal and colonic diseases. These two new capsules offer an interesting alternative to conventional endoscopy in the study of the upper and lower digestive tracts, because traditional endoscopy is often unpleasant and uncomfortable for the patient, can be painful, often requires moderate or deep sedation and is not without complications (hemorrhage, perforation, etc.). PillCam Colon is particularly important for its usefulness in the diagnosis of colonic polyps, and is a potentially useful tool in cases of incomplete colonoscopy or in colorectal cancer screening, even more when most patients are reluctant to undergo screening programs due to the said disadvantages of conventional colonoscopy. This article discusses the advantages of capsule endoscopy over conventional endoscopy, its current application possibilities and indications in routine clinical practice. In the various sections of the work, we assess the application of endoscopic capsule in different sections of the digestive tract (esophagus, stomach, and colon) and finally the potential role of panendoscopy with PillCam Colon.

Summary. Measuring von Willebrand factor (VWF)activity is essential for the diagnosis of von Willebranddisease (VWD). The VWF activity is usually assessedbased on measurement of the ristocetin cofactor (VWF:RCo). However, that test is technically challenging andhas high intra- and inter-assay variabilities. A newautomated chemiluminescent immunoassay VWFactivity has recently become commercially available(HemosIL AcuStar von Willebrand Factor RistocetinCofactor Activity). The main objective of this study wasto evaluate this new method and to compare it with theVWF:RCo assay as the reference method. We studied91 samples, 18 healthy volunteers samples and 73samples from patients (VWF:RCo level

Head-on comparative studies of factor IX (FIX) concentrates performed under standardized conditions are rarely conducted regardless of being a valuable instrument guiding health care providers towards better informed and cost-effective decisions. This study is an extension of a multicentre study that assessed the efficacy, safety and pharmacokinetics (PK) of AlphaNine(®) in 25 previously treated patients with severe haemophilia B (FIX:C ≤ 2%). After a washout period ≥ 7 days following the last PK performed with AlphaNine(®) after a dose of 65-75 IU kg(-1) , an identical PK study was performed with BeneFIX(®) on 22 of the same patients. Venous blood samples for analysis were taken at baseline and at 0.25, 0.5, 1, 3, 6, 9, 24, 48, 72 and 74 h post infusion. The outcomes of the comparison of the PK parameters were as follows: Mean (± SD) in vivo recovery (IVR) was 1.3 ± 0.4 IU dL(-1) per IU kg(-1) for AlphaNine(®) and 1.0 ± 0.3 IU dL(-1) per IU kg(-1) for BeneFIX(®) (P < 0.01). Mean terminal half-life, mean residence time, area under the curve, clearance and volume of distribution of BeneFIX(®) were 36.0 ± 12.8 h, 39.3 ± 13.9 h, 1631 ± 467 IU h dL(-1) , 0.046 ± 0.01 dL kg(-1) min(-1) and 1.75 ± 0.52 mL kg(-1) respectively. These values were not significantly different to those observed in AlphaNine(®), although BeneFIX(®) displayed higher than expected IVR values and lower than expected clearance values. In conclusion, AlphaNine(®) showed a comparable half-life, but an IVR significantly higher than that of BeneFIX(®). This dissimilarity may have implications on dosing requirements for on-demand treatment regimes affecting optimal resource allocation.

Background: adalimumab, a human anti-TNF, is an effective induction and maintenance therapy for patients with moderate to severe Crohn s disease. It seems to be effective in patients with resistance to infliximab, too, though the experience is more limited. Aim: to evaluate the efficacy of adalimumab, in patients with Crohn s disease (CD) and failure to previous treatment with infliximab. Methods: twenty-five patients with CD and failure to previous treatment with infliximab were enrolled; they were treated with 160/80 (24 patients) and 80/40 (1 patient) induction doses. We analyze clinical response to treatment with adalimumab by the Crohn’s disease Activity Index (CDAI) and plasma concentration of C-reactive protein (CRP), steroid sparing and complete fistula closure at week 48. Results: eighteen out of twenty-five patients (72%) achieved clinical remission (CDAI score < 150) at week 24 and 15/25 (60%) patients at week 48. There was a statistically significant difference (p < 0.01) in CRP serum levels from 21 to 8 mg/dl at week 48. Nine out of fifteen patients (60%) treated with corticosteroids were able to discontinue steroids. Three out of eleven patients (27%) with fistulizing Crohn s disease had complete fistula closure after the treatment. Seventy two percent of the patients (18/25) needed to increase adalimumab to weekly dose, in order to maintain clinical response. Five out of twenty-five patients (20%) had adverse events; two of them (8%) with serious adverse events (tuberculous meningitis and abdominal abscess) that forced the withdrawal of treatment. Conclusions: according to these data, adalimumab provides a clinical and analytical improvement in patients with CD and failure to previous therapy with infliximab.

OBJECTIVE To evaluate the type, frequency, and severity of macroscopic small bowel mucosal injury after chronic NSAID intake as assessed by capsule endoscopy (CE), as well as to correlate the severity of gastroduodenal and intestinal damage in these patients. MATERIAL AND METHODS A prospective, endoscopist-blind, controlled trial. Sixteen patients (14F/2M; age: 57.06 +/- 10.16 yrs) with osteoarthritis (OA) on chronic therapy with NSAIDs underwent CE and upper gastrointestinal endoscopy (UGE). Seventeen patients with OA (9F/2M; age: 57.47 +/- 9.82 yrs) who did not take NSAIDs were included as a control group. A scale ranging from 0 to 2 (0 = no lesions, 1-minor = red spots or petechiae, denuded areas and/or 1-5 mucosal breaks; 2-major = > 5 mucosal breaks and/or strictures, or hemorrhage) was designed to assess the severity of small bowel mucosal injuries. RESULTS CE found intestinal lesions in 75% (12/16) of patients in the study group and in 11.76% (2/17) of controls (p < 0.01). Seven out of 16 NSAID consumers (43.75%) and none in the control group (0%) had a major small bowel mucosal injury (p < 0.01). The percentages of patients with grade 1 and 2 gastroduodenopathy in the study group, as assessed by UGE, were 37.14 and 23.81%, respectively. There was no significant difference in the rate of major enteropathy between patients with none or minor gastroduodenal injury, and those with major gastroduodenopathy (43.75 vs. 40%; p = N.S.). CONCLUSIONS Chronic NSAID intake is associated with a high rate of small bowel mucosal injuries. Our data have failed to demonstrate a relationship between the severity of gastroduodenal and intestinal injury.

Small bowel strictures can be missed by current diagnostic methods. The Patency capsule is a new non-endoscopic dissolvable capsule which has as an objective of checking the patency of digestive tract, in a non-invasive manner. The available clinical trials have demonstrated that the Patency© capsule is a good tool for assessment of the functional patency of the small bowel, and it allows identification of those patients who can safely undergo a capsule endoscopy, despite clinical and radiographic evidence of small-bowel obstruction. Some cases of intestinal occlusion have been reported with the Patency© capsule, four of them needed surgery. So, a new capsule with two timer plugs (Agile© capsule) has been recently developed in order to minimize the risk of occlusion. This new device stars its dissolution process earlier (30 h after ingestion) and its two timer plugs have been designed to begin the disintegration even when the device is blocked in a tight stricture.

Background and objectives: the diagnostic yield of push enteroscopy (PE) varies widely from 13 to 78% of cases, according to the various series. The aim of this retrospective cohort study was to determine the endoscopic and histological yield of PE in our health area. Patients and methods: a total of 355 consecutive patients (190 males/165 females; mean age 45 years, range 15-89) underwent PE over a 6-year period, from 1997 to 2003. PE was performed under sedation and without overtube. Small-bowel mucosa biopsies were taken in 199 explorations (56%). Clinical indications for PE included: chronic diarrhea (35%), occult digestive bleeding (ODB) or iron-deficiency anemia (28%), suspected small-bowel malignancy (16%), chronic abdominal pain (28/355; 8%), follow-up of polyposis or malabsorption syndromes (7%), and abnormal radiographic findings (6%). Results: PE detected lesions in 122 cases (34%); in 6 cases (6%) lesions were within the reach of esophagogastroduodenoscopy. A normal macroscopic appearance of the small intestinal mucosa with an abnormal histological study was seen in 16 patients (6%). Major findings included: malabsorptive diseases (14%), nonspecific enteropathy (5%), angiodysplasia (3,5%), lymphangiectasia (3%); jejunal polyps (2%), Crohn's disease (2%), intestinal tumors (2%), extrinsic jejunal strictures (0.5%), and other (10/355; 3%). Abnormal radiographic findings (62%), chronic diarrhea (37%) and ODB (31%) were the indications with a higher diagnostic yield. No major complications were seen. Conclusions: according to our experience, PE is a safe and useful tool for the evaluation of small-bowel disease, especially in some indications (abnormal radiographic findings, chronic diarrhea, and ODB). Small-bowel biopsy increases PE's diagnostic yield in patients with chronic diarrhea.

Radiation enteritis is a complex clinical entity secondary to the affectation of intestinal epithelial cells as a result of radiation in the management of pelvic malignancies that may occasionally cause intestinal strictures. We present the case of a 60 year-old woman who had been diagnosed ten years before with endometrial adenocarcinoma, and who underwent hysterectomy with double adnexectomy and subsequent radiation therapy. The patient consulted for abdominal pain and ferropenic anemia of several years' standing, and had negative results following radiographic and endoscopic conventional techniques, reason why she was subjected to a capsule endoscopy study that revealed the presence of an ulcerated ileal stricture, which caused the asymptomatic retention of the capsule within the ileum. A laparotomy was subsequently performed - the strictured segment was resected and the capsule retrieved. The histologic examination of the resected segment confirmed the capsule endoscopy-raised suspicion of radiation enteritis. This case shows the role capsule endoscopy may play in the diagnosis of this condition.

Aim: to study the usefulness and safety of capsule endoscopy as a diagnostic tool in various small bowel disorders. Design: a retrospective analysis of a series of cases. Material and methods: between August 2001 and August 2002, 92 capsule endoscopy procedures were performed in 88 patients (53M/39F, age: 43.87 ± 16.78). Indications included: chronic diarrhea (n = 33); unknown abdominal pain (n = 29); occult gastrointestinal bleeding or iron-deficiency anemia (n = 13); abdominal discomfort in NSAID takers (n = 7); staging of gastrointestinal tumors (n = 4), and asymptomatic controls (n = 2). Previously performed gastroscopy, colonoscopy, and small-bowel follow-through were not conclusive in all patients. Results: most frequently relevant findings included: jejuno-ileal apthas and ulcerations (29 patients), vascular malformations (13 patients), and intestinal neoplasm (6 patients). The groups with a higher rate of findings related to this indication were occult gastrointestinal bleeding (76.92%) and chronic diarrhea (67.85%), with the lowest rate in the abdominal pain group (34.48%). Therapeutic strategy was directly changed in 36 of 88 patients (40.90%) because of capsule-endoscopic findings. The only observed complication was the failed excretion of one of the capsules because of an unknown ulcerated intestinal stricture. Conclusions: capsule endoscopy is a safe procedure which can study the entire small bowel, meaning a valuable tool for the management of patients with suggestive signs and symptoms of intestinal disorders.

Introduccion.

Introduction: several studies have pointed out the effectiveness of the PillCam© colon capsule endoscopy (CCE) compared with the colonoscopy in the study of the colonic pathology. Aims and methods: the objective of our study was to assess the agreement in the diagnosis of CCE with conventional colonoscopy as well as its sensitivity and specificity, and to describe the findings of the CCE in our clinical practice. Consecutive patients with abdominal symptoms were included in the study. The CCE was performed as previously reported (with PEG and sodium phosphate as laxative agents). The nature and location of the findings, colonic transit time, complications, cleanliness degree and consistency with diagnostic colonoscopy, when performed, were analyzed. Results: a total of 144 subjects (67 women and 77 men); (52.17±16.71 years) with the following indications were included: screening of Colorectal cancer (88 patients), control after polipectomy (24), incomplete colonoscopy (7), rectal bleeding (10), anemia (8), diarrhea (7). The CCE exploration was complete in 134/144 cases (93%), with no case of retention. The preparation was good-very good in 88/134 (65,6%), fair in 26/134 (19,4%) and poor in 20/134 (15%) of the cases. The average colonic transit was of 140.76 min (9-603). Any adverse effect was notified. In 44 cases a colonoscopy was carried out after CCE (results were hidden from another endoscopist). Compared to colonoscopy, the rate of agreement was 75,6%, the sensitivity was 84% and the specificity 62,5%, PPV was 77,7% and NPV was 71,4 %. The colonic findings in 134 CCE were: in 34 cases CCE it did not show lesions, diverticulosis in 63 explorations, polyps in 43, angiodysplasias in 15, Crohn's Disease in 9 and ulcerative colitis in other 8 cases. Conclusions: the CCE is an effective and reliable technique for the detection of lesions in colon, and because of its high agree-ment with the colonoscopy, it could be useful in clinical practice. Further studies with large seria and cost-effectiveness analysis are needed to confirm these data.
