The Revista Espanola de Enfermedades Digestivas (REED), the flagship journal for gastroenterology in the Spanish language, is now docking at a new port where this editor-in-chief (EiC), who began his trek in 2015, will now go ashore.

A 40-year-old male presented to the Emergency Department after a driving accident with blunt abdominal trauma. An abdominal computed tomography (CT) scan revealed a mesenteric injury in the right lower quadrant. He was admitted two months later due to a one-day history of abdominal pain and diarrhea, without fever or blood. The CT angiography showed a pseudoaneurysm located in the proximal ileum and several rigid small bowel (SB) loops with segmental wall thickening of mucosa.

Introduccion: la lesion de Dieulafoy en intestino delgado es una causa infrecuente de hemorragia digestiva que recidiva frecuentemente tras su tratamiento endoscopico. Material y metodos: se presenta un estudio observacional, descriptivo, retrospectivo y unicentrico de 15 pacientes con hemorragia de intestino delgado, diagnosticados de lesion de Dieulafoy con capsula endoscopica o enteroscopia doble balon, en los que se realizo tratamiento endoscopico 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 terapeutica. Se retrataron con exito dos de ellos con una nueva enteroscopia.

The purpose of this rapid review is to provide an update on the impact of SARS-CoV-2 infection on Gastroenterology and Hepatology departments, our patients, and our new way of working. The gastrointestinal tract and the liver are affected by SARS-CoV-2, especially in patients with immunosuppressive therapies. Patients with liver transplantation should be followed closely. Digestive endoscopy is a high-risk procedure for the transmission of SARS-CoV-2. While the pandemic lasts, we must adapt its indications and promote protective measures for patients and healthcare professionals alike. The COVID-19 pandemic has changed our priorities and the way we work, although we do not know what the repercussions will be after normality is reinstated.

The small bowell (SB) is a very long organ hardly accessible to conventional endoscopy. The revolution entailed by its complete diagnostic exploration with capsule endoscopy (CE) has led to a change in traditional surgical management and its related gold standard - intraoperative enteroscopy. CE is currently the first-line diagnostic strategy for the SB. An emergent technique in its wake has played a key role in the management of patients with SB conditions: to wit, device-assisted enteroscopy (DAE). Thus were developed first double-balloon enteroscopy (DBE), then single-balloon enteroscopy, and most recently motorized spiral enteroscopy.

Standard therapy using device-assisted enteroscopy includes different hemostatic therapies, polypectomy, dilation and other possibilities. The most frequent indication is small bowel bleeding. However, other specific settings could require dedicated therapies such as desinvagination, percutaneous enteroscopic jejunostomy, stent placement, endoscopic mucosal resection in polypoid vascular lesions and foreign body extraction. The present review aimed to investigate and describe device-assisted advanced therapies in the small bowel, excluding conventional hemostatic therapies of vascular lesions.

At the beginning of 2020 it is our pleasure to inform our readers about the changes in structure and future projects this journal will undertake. First of all, we wish to thank The National and International Editorial Committee, as well as the journal reviewers, for their enthusiasm, dedication, and scientific rigor in their silent and behind-the-scenes task of improving the quality of the published materials.

Introduction And Aims The growing elderly population and wide use of capsule endoscopy have led to a higher number of procedures in those patients. The aim of the present study was to assess the usefulness of capsule endoscopy in older patients. Materials And Methods All consecutive patients undergoing capsule endoscopy at our center within the time frame of 2004-2016 were classified as older (≥75 years of age) and younger. Findings and diagnostic yield were comparatively assessed. Results Of 2311 patients (mean age: 59.5 ± 19.23 years, 44.48% male), 648 were in the older group and 1663 in the younger group. Gastric transit time was shorter in the older patients ( p=0.001 ), whereas small bowel transit time was shorter in the younger patients ( p ). Overall diagnostic yield in the elderly was higher (50.66% vs . 41.19%, p ). Obscure gastrointestinal bleeding was the most frequent indication for capsule endoscopy in the elderly (90.4% vs. 53.77%, p ), achieving a higher diagnostic yield than in the younger population (51.47% vs. 42.76%, p=0.002 ), whereas Crohn's disease, suspected or known neoplasms/polyps, malabsorption syndrome, and abdominal pain were the indications in the younger patient group. Such indications were rare in the older group. Vascular lesions and active bleeding were more frequently diagnosed in the older patients, whereas ulcers/erosions and mucosal atrophy were more common in the younger patients ( p ). Conclusions Capsule endoscopy achieved a higher overall diagnostic yield in the elderly patients. Obscure gastrointestinal bleeding indication for capsule endoscopy was much more frequent in the advanced-age group and had a higher diagnostic yield.

During the 2014 Digestive Disease Week in Chicago, many high-quality studies on small-bowel endoscopy were presented. The most relevant abstracts from around the world of two complementary procedures – capsule endoscopy and deep enteroscopy – which have seen rapid changes in recent years, have been selected for this review.

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

Background: Angioectasias represents the most frequently found lesion in the small bowel by device-assisted enteroscopy for obscure gastrointestinal bleeding in Western countries. Recurrence of gastrointestinal bleeding after angioectasias therapy remains unclear and data regarding the efficacy of additional endoscopic therapeutic sessions to reduce the rebleeding rate is limited. Aim: To evaluate the rebleeding rate in small bowel angioectasias after a second endoscopic treatment with balloon-assisted enteroscopy after an initial bleed during the first endoscopic treatment. Methods: A retrospective double-center study of patients with small-bowel angioectasias undergoing a second enteroscopy treatment due to a first rebleeding episode. The endpoint was rebleeding, defined as the need for a blood transfusion, the presence of overt bleeding or a decrease in hemoglobin ≥ 2 g/dL. Results: Fifteen of 37 (40.5%) patients with small-bowel angioectasias that underwent a second endoscopic therapy after a first rebleeding episode (n = 15) experienced a second rebleeding episode. Kaplan-Meier curve analysis showed that most rebleeding episodes occurred within the first 12 months of follow-up, resulting in a rebleeding rate of 33.1% at 6 months, 39.1% at 12 months and 52.6% at 24 months. Conclusions: Despite the high absolute short-term rebleeding rate, further endoscopic treatments may be beneficial due to the effective reduction of rebleeding in a subset of patients.

Background and Aim There are few data concerning emergency double-balloon enteroscopy (DBE) and its usefulness in the management of severe acute obscure gastrointestinal bleeding (OGIB). The aim of this retrospective study was to evaluate emergency DBE and capsule endoscopy (CE) in patients with overt OGIB, analyzing the feasibility of this combined approach. Methods Emergency DBE in patients with overt OGIB was defined as performance within 24 h of symptom onset. We reported 27 patients (16 men, mean age: 64.6 ± 17.9 years) with overt severe bleeding who underwent 29 emergency DBE (22 anterograde, 7 retrograde). Of 27 patients, 16 (59.3%) underwent CE with real time (RT) viewing. Results Patients were diagnosed with the following: Dieulafoy's lesion (DL; n = 11, 40.7%), angioectasia (n = 7, 25.9%), tumors (n = 4, 14.8%), diverticulum (n = 3, 11.1%), ulcers (n = 2, 7.4%). We diagnosed 23 lesions amenable to endoscopic hemostasis and successfully treated 21 of them (77.8%). DL detection rate was statistically higher in the emergency DBE group than in OGIB patients with DBE done 24 h after symptom onset (40.7% vs 0.9%, respectively, P

Background and aim The role of capsule endoscopy (CE) in established celiac disease (CD) remains unclear. Our objective was to analyze the usefulness of CE in the suspicion of complicated CD. Methods This was a retrospective multicenter study. One hundred and eighty-nine celiac patients (mean age: 46.6 ± 16.6, 30.2% males) who underwent CE for alarm symptoms (n = 86, 45.5%) or non-responsive CD (n = 103, 54.5%) were included. Diagnostic yield (DY), therapeutic impact and safety were analyzed. Results Capsule endoscopy was completed in 95.2% of patients (small bowel transit time: 270.5 ± 100.2 min). Global DY was 67.2%, detecting atrophic mucosa (n = 92, 48.7%), ulcerative jejunoileitis (n = 21, 11.1%), intestinal lymphoma (n = 7, 3.7%) and other enteropathies (n = 7, 3.7%, six Crohn's disease cases and one neuroendocrine tumor). The DY of CE was significantly higher in patients presenting with non-responsive disease compared to patients with alarm symptoms (73.8% vs 59.3%, P = 0.035). The new findings of the CE modified management in 59.3% of the cases. There were no major complications. Conclusion Capsule endoscopy may be a moderately helpful and safe diagnostic tool in the suspicion of complicated CD, modifying the clinical course of these patients.

The gold standard in the diagnosis of gastrointestinal graft-versus-host disease (GVHD) after allogenic hematopoietic stem cell transplantation is conventional endoscopy with histopathological assessment. The role of capsule endoscopy (CE) is uncertain. The aim of the present study was to investigate the accuracy of CE in this setting, comparing the clinical, endoscopic and histological data.This was a retrospective single-centre study that included 57 (mean age: 47.18±15.05 years, 57.89% men) patients presenting with GVHD who underwent a valid CE and histopathological analysis by conventional endoscopy between January 2004 and July 2016. The endoscopic scored findings, clinical data and histopathological diagnosis were compared using duodenal histology as the gold standard.CE detected mild (n=4, 7.02%), moderate (n=6, 10.53%) and severe (n=21, 36.84%) grades, with a higher diagnostic yield than conventional endoscopy (54.39 vs. 28.07%, P0.001). A positive CE predicted positive histology (80.64 vs. 15.38%, P0.001) with a sensitivity, specificity, negative predictive value and accuracy of 86.21, 78.57, 84.62 and 82.46%. This procedure detected more mild-to-moderate histological lesions than conventional endoscopy (8.77 vs. 3.51%, P=0.25). In addition, 16% of patients with a previous normal endoscopy with biopsies had a pathological CE and there were eight (25.81%) patients with positive CE images unreachable by conventional endoscopy.CE is a useful device in GVHD, achieving high accuracy values and diagnostic yield. However, its results may be interpreted in conjunction with clinical and histological features, particularly in mild-to-moderate stages.

espanolIntroduccion y objetivo: la capsula endoscopica y la enteroscopia de doble balon son tecnicas de reconocido valor en el estudio de la hemorragia digestiva media, habiendo numerosos factores que pueden afectar a su rendimiento diagnostico. El objetivo del presente estudio es el de caracterizar y definir los niveles de concordancia entre ambas focalizando en el tipo de lesion, en una gran cohorte de pacientes de un centro de referencia. Material y metodo: entre los anos 2004-2014 se administraron 1.209 capsulas 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 tecnicas tuvieron un rendimiento diagnostico similar (70,5% vs. 69,6%, p = 0,9). El rendimiento diagnostico global de la enteroscopia fue superior en pacientes con una capsula previa positiva (79,3% vs. 27,9%, p 0,55-0,77]), tumores (0,66 [95% IC: 0,55-0,76]) y moderada para ulceras (0.56 [95% IC: 0,46-0,67]). Los diverticulos (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 capsula endoscopica y la enteroscopia de doble balon de forma global sean similares, hay numerosos factores que pueden modificar estos valores, siendo el principal el tipo de lesion. EnglishBackground 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 0.46-0.67]). 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.

AIM To analyze the diagnostic yield (DY), therapeutic impact (TI) and safety of capsule endoscopy (CE). METHODS This is a multi-centre, observational, analytical, retrospective study. A total of 163 patients with suspicion of celiac disease (CD) (mean age = 46.4 ± 17.3 years, 68.1% women) who underwent CE from 2003 to 2015 were included. Patients were divided into four groups: seronegative CD with atrophy (Group- ?, n = 19), seropositive CD without atrophy (Group- ?, n = 39), contraindication to gastroscopy (Group-?, n = 6), seronegative CD without atrophy, but with a compatible context (Group-?, n = 99). DY, TI and the safety of CE were analysed. RESULTS The overall DY was 54% and the final diagnosis was villous atrophy (n = 65, 39.9%), complicated CD (n = 12, 7.4%) and other enteropathies (n = 11, 6.8%; 8 Crohn's). DY for groups ? to ? was 73.7%, 69.2%, 50% and 44.4%, respectively. Atrophy was located in duodenum in 24 cases (36.9%), diffuse in 19 (29.2%), jejunal in 11 (16.9%), and patchy in 10 cases (15.4%). Factors associated with a greater DY were positive serology (68.3% vs 49.2%, P = 0.034) and older age (P = 0.008). On the other hand, neither sex nor clinical presentation, family background, positive histology or HLA status were associated with DY. CE results changed the therapeutic approach in 71.8% of the cases. Atrophy was associated with a greater TI (92.3% vs 45.3%, P < 0.001) and 81.9% of the patients responded to diet. There was one case of capsule retention (0.6%). Agreement between CE findings and subsequent histology was 100% for diagnosing normal/other conditions, 70% for suspected CD and 50% for complicated CD. CONCLUSION CE has a high DY in cases of suspicion of CD and it leads to changes in the clinical course of the disease. CE is safe procedure with a high degree of concordance with histology and it helps in the differential diagnosis of CD. © The Author(s) 2017. Published by Baishideng Publishing Group Inc.

Double balloon enteroscopy (DBE) is an endoscopic technique broadly used to diagnose and treat small bowel diseases. Among the associated complications of the oral DBE, post-procedure pancreatitis has taken the most attention due to its gravity and the thought that it might be associated to the technique itself and anatomical features of the pancreas. However, as the etiology has not been clarified yet, this paper aims to review the published literature and adds new results from a porcine animal model. Biochemical markers, histological sections and the vascular perfusion of the pancreas were monitored in the pig during DBE practice. A reduced perfusion of the pancreas and bowel, the presence of defined hypoxic areas and disseminated necrotic zones were found in the pancreatic tissue of pigs. All these evidences contribute to support a vascular distress as the most likely etiology of the post-DBE pancreatitis.

To analyse the diagnostic efficacy of oral push-type enteroscopy (PE) according to indications. To assess evolution in patients with occult gastrointestinal bleeding (OGIB) according to findings and endoscopic therapy.204 PE performed in 167 patients: OGIB: 117, Crohn's disease: 34, radiological abnormalities: 21; chronic diarrhoea: 12; intestinal sub-occlusion: 11; polyposis: 7; other: 2. We followed clinical outcome in 72 patients after PE for OGIB. They were separated according to findings and endoscopic therapy: no findings: 32; no treated angiodysplasia: 10; treated angiodysplasia: 20; other lesions: 10. We evaluated the number of admissions and transfusional requirements before and after PE, re-bleeding and surgical treatment. Statistics were performed using Student's t test and Chi-square test (statistical significance p0.05).We diagnosed lesions in 65.8% PE for OGIB, angiodysplasia being the more frequent finding (33.3%). We found lesions before Treitz in 15.4% A higher diagnostic efficacy was seen in active bleeding (83.4%) versus anaemia (52.2%), p0.05. After PE both admissions and transfusional requirements decreased in all subgroups specially in treated angiodysplasias and other lesions, nearly reaching statistical significance (p = 0.07). Re-bleeding occurred in 50% of non-treated lesions versus 20-25% in treated lesions. We found lesions in 47% of PE for Crohn's disease, in 52.4% for radiological abnormalities, in 41.6% for chronic diarrhoea and in 0% for intestinal sub-occlusion.PE is efficient in the diagnosis and therapy of patients with OGIB, Crohn's disease and radiological abnormalities. Its usefulness is controversial in the study of chronic diarrhoea and intestinal sub-occlusion.
