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...

INTRODUCTION: Objective assessment of Crohn's disease (CD) activity in patients treated with anti-tumour necrosis factor (anti-TNF) antibodies is crucial for the prediction of its long-term results. Mucosal healing estimated endoscopically has a strong predictive value; however, only combined assessment together with transmural healing in magnetic resonance enterography (MRE) gives full information about the whole spectrum of inflammatory lesions in CD. AIM: To assess the usefulness of intestinal healing phenomenon in CD, defined as improvement both in endoscopy and MRE, after anti-TNF induction therapy, in predicting long-term results of 1-year treatment...

BACKGROUND: Mesenteric panniculitis (MP) is mostly an associated sign of an intra-abdominal or systemic inflammatory primary disease. Nevertheless, etiological and differential diagnosis of idiopathic MP can be challenging when an associate primary cause is not in the foreground. METHODS: We report here the case of an isolated small bowel Crohn's disease, long time considered as idiopathic MP. RESULTS: This patient presented to our department with a 10-year history of acute abdominal symptoms evolving with flare-up and remission...

BACKGROUND: Magnetic resonance enterography (MRE) is an accurate examination for assessing activity in Crohn's disease (CD). Various MRE indices have been developed for that purpose, but have not been directly compared. The aim of the study was to compare the diagnostic accuracy of three MRE indices for detecting and grading disease activity in CD, using endoscopy as gold standard. METHODS: MRE and ileocolonoscopies performed within 1 month in 43 patients with CD were analyzed...

BACKGROUND: Video capsule endoscopy (VCE) and magnetic resonance enterography (MRE) are the prime modalities for the evaluation of small bowel (SB) Crohn's disease (CD). Mucosal inflammation on VCE is quantified using the Lewis score (LS). Diffusion-weighted (DW) magnetic resonance imaging (MRI) allows for accurate assessment of SB inflammation without administration of intravenous contrast material. The Magnetic Resonance Index of Activity (MaRiA) and the Clermont index are quantitative activity indices validated for contrast-enhanced MRE and DW-MRE, respectively...

Crohn's disease affects more than 500000 individuals in the United States, and about 25% of cases are diagnosed during the pediatric period. Imaging of the bowel has undergone dramatic changes in the past two decades. The endoscopy with biopsy is generally considered the diagnostic reference standard, this combination can evaluates only the mucosa, not inflammation or fibrosis in the mucosa. Actually, the only modalities that can visualize submucosal tissues throughout the small bowel are the computed tomography (CT) enterography (CTE) with the magnetic resonance enterography (MRE)...

BACKGROUND: MR enterography (MRE) is useful for evaluating transmural lesions and extra-intestinal complications of Crohn's disease (CD). The aim of this study was to prospectively evaluate whether MRE could detect severe strictures and inflammatory lesions in patients who lost the responsiveness to anti-TNF treatment and whether MRE could predict prognosis of CD patients with clinical remission. PATIENTS AND METHODS: MRE were conducted in 50 patients who were treated with infliximab or adalimumab...

Early recognition of Crohn's disease with initiation of disease-modifying therapy has emerged as a prominent inflammatory bowel disease management strategy. Clinical practice and trials have often focused on patient symptoms, and more recently, serologic tests, stool inflammatory markers, and/or endoscopic inflammatory features for study entry criteria, treatment targets, disease activity monitoring, and to assess therapeutic response. Unfortunately, patient symptoms do not correlate well with biological disease activity, and endoscopy potentially misses or underestimates disease extent and severity in small bowel Crohn's disease...

Mild Crohn's disease (CD) is classified as those patients who are ambulatory, with <10 % weight loss, are eating and drinking without abdominal mass, tenderness, obstructive symptoms, or fever, and endoscopically they have non-progressive mild findings. Initial evaluation of mild CD should focus on assessment for high-risk features requiring more aggressive therapy. In contrast to moderate-to-severe disease, where therapy is focused on mucosal healing, the management of mild CD is focused on symptom management, while exposing the individual to minimal therapeutic risks...
