[X-ray examination of small intestine--conventional enteroclysis and CT enterography].

We gave an outline while showing the image about conventional enteroclysis and CT enterography as X-ray examination of small intestine. Recently a double balloon enteroscopy and wireless capsule endoscopy have been used as new procedure for small intestinal examination. The former is high invasive examination for a patient and has a risk of perforation for the patients with intestinal adhesion and consequently it is unsuitable as screening examination. And for the latter, the stoppage to stenosis locus of a capsule becomes a problem for a patient having intestinal stenosis. Therefore, a conventional enteroclysis is still necessary at present. On the other hand, CT enterography which is new small intestinal examination procedure is attracting attention as the examination of low invasiveness except the exposure to radiation and equally taking very short time during examination. CT enterography will be it with more and more useful examination for the small intestine in a diagnosis of intestinal neoplasia, ileus and inflammatory bowel disease such as Crohn's disease in future.
