Recidiva hemorrágica de intestino delgado por lesión de Dieulafoy tras tratamiento endoscópico combinado / No disponible

INTRODUCCIÓN: la lesión de Dieulafoy en intestino delgado es una causa infrecuente de hemorragia digestiva que recidiva frecuentemente tras su tratamiento endoscópico. MATERIAL Y MÉTODOS: se presenta un estudio observacional, descriptivo, retrospectivo y unicéntrico de 15 pacientes con hemorragia de intestino delgado, diagnosticados de lesión de Dieulafoy con cápsula endoscópica o enteroscopia doble balón, en los que se realizó tratamiento endoscópico combinado. Resultados y conclusiones: durante una mediana de seguimiento de 33,5 meses (rango 2-145), recidivaron tres de los 12 casos que se pudieron seguir (25 %) y todos ocurrieron precozmente en las primeras 48 horas tras la terapéutica. Se retrataron con éxito dos de ellos con una nueva enteroscopia

Recurrent small-bowel bleeding from a Dieulafoy's lesion after combined endoscopic treatment.

INTRODUCTION: Dieulafoy's lesion of the small bowel is an uncommon cause of gastrointestinal (GI) bleeding that often recurs after endoscopic treatment. MATERIAL AND METHODS: we report an observational, descriptive, retrospective, single-center study in 15 patients with small bowel bleeding who were diagnosed with a Dieulafoy's lesion by capsule endoscopy or double-balloon enteroscopy. RESULTS AND CONCLUSIONS: all patients underwent combined endoscopic treatment. During a median follow-up of 33.5 months (range, 2-145), three of the 12 cases that stayed in follow-up (25 %) recurred, all within 48 hours after treatment. Two were successfully re-treated with a repeat endoscopic procedure.

Intermediate-risk patients with three to four small adenomas should be considered low risk for colorectal cancer screening.

BACKGROUND AND AIM: Intermediate-risk patients following a colorectal cancer screening program may have differential risk of advanced lesions depending on the findings of an index colonoscopy. The aim of the present study was to comparatively assess advanced colorectal neoplasia risk at the first follow-up colonoscopy among the different intermediate-risk subgroups with a focus on patients with three to four adenomas. METHODS: All patients recruited for a baseline screening colonoscopy between 2006 and 2011 were included. Number, size and histopathological characteristics of adenomas were collected. Main outcome was an advanced colorectal neoplasia detection rate (invasive carcinoma or advanced adenoma) at the first follow-up colonoscopy. Low- and high-risk patients were excluded. RESULTS: Five hundred and sixty-one intermediate-risk patients (63.3% men, mean age: 59.01 ± 6.16 years) underwent indexing and follow-up colonoscopy. By multivariate analysis, three to four adenomas (OR: 3.613 [95% CI: 1.661-7.859], P = 0.001) and adenoma size ≥10 <20 mm (OR: 3.374 [95% CI: 1.618-7.034], P = 0.001) were independent factors associated with advanced colorectal neoplasia. Advanced lesions were detected in 7.66% of cases. Of patients with advanced colorectal neoplasia, 51.16% belonged to the three-to-four-adenoma group and ≥1 of ≥10 <20-mm subgroups (n = 132, 23.53%). These patients demonstrated a higher rate of advanced lesions [OR: 3.886 (95% CI: 2.061-7.325), P < 0.001] than patients with three to four small adenomas of <10 mm (16.67% vs 5.07%, P < 0.001). The association between patients with small adenomas (n = 217, 38.68%) and advanced lesions was not significant (OR: 0.521 [95% CI: 0257-1.056], P = 0.066). CONCLUSION: Intermediate-risk patients with three to four small adenomas achieved a very low advanced lesion rate at follow up. Surveillance interval should be lengthened because these patients should be considered low risk.

Concordancia diagnóstica entre la cápsula endoscópica y enteroscopia de doble balón en la hemorragia digestiva media en un centro de referencia / Diagnosis agreement between capsule endoscopy and double-balloon enteroscopy in obscure gastrointestinal bleeding at a referral center

INTRODUCCIÓN Y OBJETIVO: la capsula endoscópica y la enteroscopia de doble balón son técnicas de reconocido valor en el estudio de la hemorragia digestiva media, habiendo numerosos factores que pueden afectar a su rendimiento diagnóstico. El objetivo del presente estudio es el de caracterizar y definir los niveles de concordancia entre ambas focalizando en el tipo de lesión, en una gran cohorte de pacientes de un centro de referencia. MATERIAL Y MÉTODO: entre los años 2004-2014 se administraron 1.209 cápsulas en 1.078 pacientes y se realizaron 381 enteroscopias en 361 pacientes con hemorragia digestiva media. RESULTADOS: en 332 pacientes (edad media: 65,22 ± 15,41, 183 hombres) se realizaron ambos procedimientos. Ambas técnicas tuvieron un rendimiento diagnóstico similar (70,5% vs. 69,6%, p = 0,9). El rendimiento diagnóstico global de la enteroscopia fue superior en pacientes con una cápsula previa positiva (79,3% vs. 27,9%, p < 0,001). La concordancia diagnóstica entre los resultados por cápsula y enteroscopia para cada lesión fue muy buena para pólipos (0,89 [95% IC: 0,78-0,99]), buena en las lesiones vasculares (0,66 [95% IC: 0,55-0,77]), tumores (0,66 [95% IC: 0,55-0,76]) y moderada para úlceras (0.56 [95% IC: 0,46-0,67]). Los divertículos (0,39 [95% IC: 0,29-0,5] tuvieron una concordancia razonable. Los resultados entre ambos procedimientos difirieron en 73 pacientes (22%). CONCLUSIONES: el presente estudio evidencia que aunque el rendimiento de la cápsula endoscópica y la enteroscopia de doble balón de forma global sean similares, hay numerosos factores que pueden modificar estos valores, siendo el principal el tipo de lesión

BACKGROUND AND AIM: Capsule endoscopy and doubleballoon enteroscopy are well-recognized procedures in obscure gastrointestinal bleeding, with many factors that may influence their diagnosis yield. The aim of the present study was to characterize the degree of agreement between both techniques with focus on the type of lesion in a large cohort of patients at a referral center. MATERIAL AND METHOD: One thousand two hundred and nine capsules were administered in 1,078 patients and 381 enteroscopies were performed in 361 patients with obscure-gastrointestinal bleeding from 2004 to 2014. RESULTS: Both procedures were carried out in 332 patients (mean age: 65.22 ± 15.41, 183 men) and they have a similar diagnosis yield (70.5% vs. 69.6%, p = 0.9). Overall enteroscopy diagnosis yield was higher within patients with a previous positive capsule endoscopy (79.3% vs. 27.9%, p < 0.001). The degree of agreement was very good for polyps (0.89 [95% CI: 0.78-0.99]), good for vascular lesions (0.66 [95% CI: 0.55-0.77]) and tumors (0.66 [95% CI: 0.55-0.76]) and moderate for ulcers (0.56 [95% CI: 0.46-0.67]). Diverticula (0.39 [95% CI: 0.29-0.5]) achieved a fair agreement. The results of CE and DBE differed in 73 patients (22%). CONCLUSIONS: The present study confirms that although overall diagnostic yield by capsule endoscopy and double-balloon enteroscopy is similar, there are many factors which can modify these values, mainly the type of lesion

Enfermedad de Ménétrier / Ménétrier’s disease

La enfermedad de Ménétrier es una gastropatía muy infrecuente de etiología desconocida. Esta enfermedad produce engrosamiento de los pliegues gástricos. Es una condición preneoplásica, ya que se asocia a cáncer gástrico en un 15 por ciento de los casos. Presentamos a un paciente de 56 años que ingresa por dolor en la parte media de hemiabdomen superior, pérdida de apetito y vómitos. Se diagnostica la enfermedad por endoscopia y biopsia. Se realiza una puesta al día del tratamiento, que hasta la fecha no ha sido definido de forma clara.

Disfagia de larga evolución en paciente con esofagitis eosinofílica / Dysphagia of long evolution in a patient with eosinophilic esophagitis

La esofagitis eosinofílica (EE) es una enfermedad producida por la presencia de un infiltrado de eosinófilos en el esófago en ausencia de enfermedad por reflujo gastroesofágico (ERGE). Cursa con disfagia, impactación de alimentos en el esófago, pirosis y en niños son frecuentes los vómitos y regurgitaciones. Presentamos el caso de una mujer que consulta por disfagia de larga evolución, se realiza estudio endoscópico con toma de biopsias esofágicas, diagnosticando una EE. Tras realizar tratamiento con corticoides tópicos mejora de la disfagia.
