Enteroscopy-guided Contrast Radiography of Small Bowel Lesions

the gastrointestinal tract to evaluate because of its long length, complex looped configuration, and also because of its distant location. Only the proximal portion of the jejunum and the terminal ileum can be examined with the use of upper gastrointestinal endoscopy and colonoscopy. Thus, other examination tools such as small bowel follow-through, enteroclysis, capsule endoscopy and double-balloon enteroscopy are used to evaluate entire small bowel loops. Recently, double-balloon enteroscopy (DBE), a new method that allows visualization of entire small bowel, is being frequently used in clinical settings. It also enables to take biopsy specimens, therapeutic interventions and contrast radiography. In our department, we introduced enteroscopy-guided contrast radiography (ECR) of small bowel lesions by injecting water-soluble contrast medium via a side hole of the enteroscope. The aim of this prospective study was to evaluate the usefulness of ECR and to demonstrate the ECR finding of various small bowel lesions. J Korean Radiol Soc 2007;56:261-266
