Crohn's disease is one of the major subtypes of idiopathic inflammatory bowel disease and is characterized by chronic transmural intestinal inflammation of the gastrointestinal tract anywhere from mouth to the anus, with a predilection for the small bowel. Cross-sectional imaging with computed tomography and magnetic resonance enterography plays a key role in confirming diagnosis, identifying and managing complications, assessing disease severity, and identifying response to medical therapy. This review will focus on the role of radiologists in the diagnosis and assessment of Crohn's disease...

Background and study aims Clinical impact of single-balloon enteroscopy (SBE) is fairly known, as well as its diagnostic yield comparing with other small bowel gastrointestinal investigations. This study represents a contribution to better understand it and is designed to evaluate SBE efficacy and degree of concordance with previous evaluation of small bowel. Patients and methods This is a single-center retrospective study of patients that underwent SBE with suspected small bowel disease based on non-invasive imaging...

PURPOSE: To assess small bowel abnormalities on magnetic resonance enterography (MRE) in adult patients with nonresponsive celiac disease (CD) and investigate their associations with endoscopic, histopathologic, serologic, and genetic features. MATERIALS AND METHODS: This prospective study was carried out between September 2012 and August 2013. After approval by the Ethics Committee of our institution, informed consent was acquired from all participants. Forty consecutive patients with nonresponsive CD, aged 17-76 years, underwent MRE using a 1...

OBJECTIVE: To assess if magnetic resonance enterography is capable of showing evidence/extent of disease in pediatric patients with biopsy-proven celiac disease by comparing with a control group, and to correlate the magnetic resonance enterography findings with anti-endomysial antibody level, which is an indicator of gluten-free dietary compliance. METHODS: Thirty-one pediatric patients (mean age 11.7±3.1 years) with biopsy-proven celiac disease and 40 pediatric patients as a control group were recruited in the study...

BACKGROUND/AIM: Although international guidelines in inflammatory bowel disease (IBD) management are currently available, variations in IBD care still exist. The aim of this study was to determine the extent of the variation in IBD care among Saudi pediatric gastroenterologists. MATERIALS AND METHODS: A cross-sectional survey was conducted among all pediatric gastroenterologists who were members of the Saudi Society of Pediatric Gastroenterology, Hepatology, and Nutrition (SASPGHAN) from August 2015 to December 2015...

OBJECTIVE: The efficacy of anti-tumour necrosis factors (anti-TNFs) in patients with Crohn's disease (CD) and symptomatic small bowel stricture (SSBS) is controversial. The aim of this study was to estimate the efficacy of adalimumab in these patients and to identify the factors predicting success. DESIGN: We performed a multicentre, prospective, observational cohort study in patients with CD and SSBS. The included patients underwent magnetic resonance enterography at baseline and subsequently received adalimumab...

BACKGROUND: Diffusion-weighted imaging (DWI) is a novel technique to evaluate bowel inflammation in Crohn's disease (CD). It remains unclear whether DWI could differentiate grades of inflammation activity and add to the accuracy of conventional magnetic resonance enterography (MRE) in defining disease activity. We aimed to assess the accuracy of DWI for evaluating ileocolonic CD inflammation compared with conventional MRE, using ileocolonoscopy as reference standard. METHODS: This was an observational study of CD patients who underwent both ileocolonoscopy and MRE with DWI...

BACKGROUND Magnetic resonance enterography (MRE) has become the modality of choice in assessment of patients with Crohn's disease (CD). We aimed to present our experience on 300 patients with CD who underwent MRE during the first 30 months after setting up MRE for the first time in a referral center in Iran. METHODS Patients with a definite diagnosis of CD based on either ileocolonoscopy or histopathological studies were included in the final report and categorized into four phenotypes of inactive, active, stricturing, and penetrating disease...

BACKGROUND: The Lémann index (LI), calculated by magnetic resonance (MR) or computed tomography enterography in association with endoscopy, was developed to assess bowel damage (BD) in Crohn's disease (CD). Our aim was to investigate the concordance between ultrasonography-based Lèmann index (US-LI) and magnetic resonance-based Lèmann index (MR-LI). METHODS: We prospectively evaluated all consecutive patients with CD referred to our IBD Unit. All patients had undergone endoscopy, US and MR within 1 month...

The most common small bowel inflammatory disorders include Crohn disease, nonsteroidal antiinflammatory drug (NSAID) enteropathy, and celiac disease. Capsule endoscopy, computed tomography enterography, and magnetic resonance enterography have a complementary role in the diagnosis of Crohn disease and evaluation of patients with established Crohn disease. The higher risk of capsule retention with known Crohn disease and NSAID enteropathy can be minimized by cross-sectional imaging or the patency capsule. The main role of deep enteroscopy is tissue diagnosis, endoscopic management of small bowel lesions and strictures, and retrieval of retained capsules...

Patients previously classified with "obscure gastrointestinal hemorrhage" should now be classified as "suspected small bowel bleeding" according to the 2015 American College of Gastroenterology guidelines. This article provides algorithms for how to manage patients with suspected small bowel bleeding, including utilization of second-look endoscopy and/or colonoscopy, video capsule endoscopy, computed tomographic enterography, magnetic resonance enterography, angiography, and deep enteroscopy.

Radiology examinations play a major role in the diagnosis, management, and surveillance of small bowel diseases and are complementary to endoscopic techniques. Computed tomography enterography and magnetic resonance enterography are the cross-sectional imaging studies of choice for many small bowel diseases. Angiography still plays an important role for catheter-directed therapies. With the emergence of hybrid imaging techniques, radionuclide imaging has shown promise for the evaluation of small bowel bleeding and Crohn disease and may play a larger role in the future...

Crohn disease (CD) and ulcerative colitis (UC) are the two main forms of idiopathic inflammatory bowel disease (IBD). CD is a transmural chronic inflammatory disorder that can affect any part of the gastrointestinal tract in a discontinuous distribution. UC is a mucosal and submucosal chronic inflammatory disease that typically originates in the rectum and may extend proximally in a continuous manner. In treating patients with CD and UC, clinicians rely heavily on accurate diagnoses and disease staging. Magnetic resonance (MR) enterography used in conjunction with endoscopy and histopathologic analysis can help accurately diagnose and manage disease in the majority of patients...

Meckel's diverticulum (MD) is estimated to affect 1%-2% of the general population, and it represents a clinically silent finding of a congenital anomaly in up to 85% of the cases. In adults, MD may cause symptoms, such as overt occult lower gastrointestinal bleeding. The diagnostic imaging workup includes computed tomography scan, magnetic resonance imaging enterography, technetium 99m scintigraphy (99mTc) using either labeled red blood cells or pertechnetate (known as the Meckel's scan) and angiography. The preoperative detection rate of MD in adults is low, and many patients ultimately undergo exploratory laparoscopy...
