Capsule Endoscopy and Small Bowel Enteroscopy: Have They Rendered the Radiologist Obsolete?

Abstract:
Capsule endoscopy (CE) provides visualization of small bowel mucosa for evidence of inflammation. Given its ability to detect subtle mucosal changes, CE is recommended in the diagnostic work-up of small bowel Crohn disease (CD) and also in monitoring mucosal response to therapy in nonstricturing CD. Patency capsule and cross-sectional imaging can reduce risk of capsule retention in patients with suspected stenotic disease. CE is complementary to magnetic resonance enterography, which can provide extraintestinal information. Device-assisted enteroscopy has limited role in CD.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
