Diagnosis of Small Bowel Tumors
Enteroclysis Sometimes push endoscopy or capsule video endoscopy Enteroclysis (sometimes CT enteroclysis) is probably the most common study for mass lesions of the small bowel. Enteroclysis involves administration of contrast into the stomach followed by fluoroscopic imaging via a series of x-rays to visualize intestinal motility and wall abnormalities. CT enteroclysis combines enteroclysis with standard abdominal CT. Push endoscopy of the small bowel with an enteroscope may be used to visualize and biopsy tumors. Video Capsule Endoscopy can help identify small-bowel lesions, particularly bleeding sites; a swallowed capsule transmits 2 images/second to an external recorder. The original capsule is not useful in the stomach or colon because it tumbles in these larger organs; a colon capsule camera with better optics and illumination is under development for use in these larger-diameter organs.
