Inflammatory disease of the X-ray diagnosis of gastrointestinal X ray examination Yao on the mild, moderate, not high and the UC diagnosis and imaging techniques and conditions related to Crohn"s disease but do have a higher value. Are summarized as follows:
First, the UC X-ray
UC mainly involving the rectum, sigmoid colon, part of the descending colon can be affected, transverse colon, and even the entire colon. Therefore, X-ray double contrast barium examination method, clearly shows that as the colon mucosa outline form, ulcers and inflammatory polyps, and to understand the scope of disease, and complications such as degree of involvement. However, cases of severe or fulminant UC, in order to avoid complications, should wait until after the condition improved. Fasting before the test meal, taking mannitol, Nursing and slowly drink laxative, do not drink cause acute vomiting or abdominal distension induced by intestinal perforation expansion.上海第一人民医院消化科吴坚炯

UC X-ray findings are:
1, the intestinal mucosal folds contour and acute changes in bowel mucosa of the lesion is diffuse edema, intestinal blurry edges, loss of normal mucosal folds form thick mucous membrane disorder. Most of the small shallow ulcers and secretions can thin or thick contour lines appear jagged burrs or changed. If the formation of inflammatory polyps, can be seen by the numerous round or oval filling defect. Mucosal lesions may be due to chronic fibrosis and showed granular changes in bowel rough or rugged. Mucosa after row of barium mucosal disturbance as shown, the more easily see the sizes of inflammatory polyps of the image.
2, changes in colonic bag Run acute diffuse inflammation caused by bowel wall edema and ulceration, can cause colon bags disappear. When the lesions improved, intestinal bags can be re-appears. Development of chronic or recurrent fibrosis has occurred due to the intestinal wall, colonic continuity disappears bags. 3, intestinal morphological changes (1) intestinal stenosis, acute intestinal inflammation due to infiltration, allows the expansion of intestinal spasm of the limitations caused by restricted or narrow the intestine, but after the narrow if remission can disappear. Development of advanced or recurrent intestinal fibrosis by multiple inflammatory polyps of varying sizes, can cause permanent intestinal stenosis. (2) intestinal
Shortening, rigidity, diastolic and systolic function disappeared, the so-called "lead pipe "-like or" sausage ", inflation will not make the lumen expansion. Bowel disease after barium filling may be due to dysfunction of the row of barium weakened, intestine caused by left large amounts of barium. such as acute exacerbation of patients was extremely lumen expansion is acute in the characteristics of toxic megacolon (diameter 8cm). must be noted that UC X-ray findings and clinical performance is not necessarily proportional. In particular, cases of early or light, X-ray abnormalities may be no, X-ray section of diseases of the rectum a few worthless.
4, "paving stone"-like changes can also occur with severe UC, "paving stone"-like change, "paving stone" kind of change is the collapse of the remnants of the mucosal ulcers and the formation of the convex surface of the island, while barium attached to the uneven generated images.
X-ray findings of Crohn"s disease Crohn"s disease occurred in the ileum better and adjacent colon, a few can occur in the stomach, duodenum, jejunum and other parts. X-ray examination is an important means of diagnosis of Crohn"s disease. There are reports that experienced radiologists can reach the correct diagnosis rate of 90%. Especially the use of double contrast barium, supplemented by improved techniques can increase the positive rate. Suspected ileocecal, colonic lesions, it is desirable for the barium enema examination when necessary, and barium enema have used two methods.

X-ray findings of Crohn"s disease are:
1, Crohn"s disease lesions were typical of the segmental distribution, inflatable segment stenosis limits of expansion and a clear, normal bowel disease intestine are separated between the lesion can be single or multiple, but the more common multiple.
2, early lesions due to inflammatory edema of submucosa, mucosal fold thickening and disorders. Bowel disease compared with a fixed shape, but no significant stenosis performance, close to the normal bowel disease can have a normal section, relaxation and creep functions.
3, the lesion extended to the submucosa, a lot of granulation tissue, in addition to disturbance of mucosal folds, thickening, but may be a "paving stones (pebbles)"-like filling defect in the bags disappear colon, bowel irregularity.
4, erosion of the intestinal wall lesions can be seen when full-thickness round or longitudinal fissure Kanying ulcers, when the barium filling the intestine, its jagged contours or spikes-like prominence, which is the Kanying.
5, advanced cases, the ulcer healing process of scar contraction of granulation tissue and submucosa, leading to reduced intestinal luminal irregular stenosis, usually manifested in the expansion of the proximal stenosis. Small bowel Crohn"s disease may be due to the emergence of segmental distribution of lesions were more narrow, that is, lesions were "jumping" phenomenon, a narrow section of each of varying lengths, often above the range of 2cm. Irregular bowel showed a narrow thin strip shadow, called the line-like symptoms. Bowel disease of the bowel wall stiffness, creep completely disappear.
6, gall tube formation, the Yin Kelong disease often full-thickness erosion of the colon wall, easy to produce mass and intra-abdominal abscess, adhesions of intestinal loops, showing the vicinity of the barium bowel disease with another directly connected to the communication occurred between the intestinal curve, called fistula. Many have intestinal adhesions between music phenomena, such as barium filling of the road leading to atrophy of abdominal wall, you are prompted for the fistula. Barium and endoscopy with the application if, it will undoubtedly be able to catch the high rate of correct diagnosis of inflammatory bowel disease
