[Abstract]:Aim: to evaluate the feasibility of instillation of 0.9% saline multi-slice spiral CT enterography (multislice CT enterography, MSCTE) by catheterization and to evaluate the clinical application value of CT enterography in intestinal diseases. Methods: from December 2009 to April 2012, 29 patients with suspected small bowel disease were enrolled in this study. The 0.9% saline solution was infused with 0.9% saline solution with a continuous and uniform rate of 1500ml, usually 1500ml, within 30 minutes before the scan. According to the patient's tolerance and the patient's body weight, an appropriate increase of 500ml was achieved individually in order to achieve the full dilation of the small intestine segments in order to achieve the full expansion of each segment of the small intestine. The hypotension drug 654mg / 210mg was injected intramuscularly at 20 minutes after perfusion of contrast agent (i.e. 10 minutes before scanning). The whole abdomen CT plain scan and contrast enhanced scan were performed immediately after the perfusion of normal saline. The data of the degree of intestinal dilatation in 29 patients were statistically analyzed. Results: (1). Multi-slice spiral CT enterography was successfully performed in 29 patients with abdominal distension except for slight abdominal distension. (2). 0.9% 0.9% saline multi-slice spiral CT enterography can appropriately dilate the intestinal cavity. The average intestinal filling score of 29 patients was 2.82 points, and the average filling degree of jejunum was 2.5points. The average filling score of ileum was 2.75. 23 cases were expanded to 3 grade, 4 cases to 2 grade, and 2 cases to 1 grade. The average dilation degree of jejunum and ileum were 20.5 鹵3.6mm and 19.0 鹵3.2mm, respectively. There was no significant difference between empty and ileal dilation (P0.05). (- 3). There were 5 cases of small intestinal tumors, 7 cases of active Crohn's 's disease, 2 cases of intestinal tuberculosis, 1 case of other diseases and 14 cases without abnormal findings (2 of which were false negative). (4) by multi-slice spiral CT enterography. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 88.2%, 100%, 93.1%, 100%, 85.7%, respectively. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 88.2%, 100%, 93.1%, 100%, 85.7%, respectively. Conclusion: (1) 0.9% saline has the same osmotic pressure as the normal human plasma and tissue fluid, which is in accordance with physiological conditions. As a negative contrast agent of CT in small intestine, it can dilate the small intestine very well. It can be used as a reasonable contrast medium for the diseased small intestine without aggravating the patient's condition. (2). Multi-slice spiral CT enterography with catheterization can dilate the intestinal tract easily find and display intestinal lesions and have high sensitivity specificity and accuracy.
