The Clinical Value Of Intubation MSCT Of Small Bowel With0.9%Saline

Objective:To assess the feasibility of multislice spiral CT enterography (MSCTE) with intubation perfusion of the large dose0.9%saline solution and to explore the clinical value of the small intestine imaging of intubation in the gastro-intestinal diseases.Methods:To our hospital in December2009to April2012,29cases of suspected small bowel disease patients were examined. After all patients were assigned to Intubation infusion of0.9%saline solution1500-2000ml in30minutes,1500ml in generally, individual tolerated by patients and patient weight appropriate to increase500ml, in order to achieve full expansion of the small intestine. When perfusion contrast agent20minutes (before10minutes of the scan) intramuscular hypotonic drugs654-210mg. Abdominal CT scan and enhanced scan was performed after saline perfusion.28patients with intestinal dilatation degree statistics were performed.Results:(1) Intubation multislice CT small bowel imaging in29patients were successfully completed MSCTE check, in addition to find a little bloating, no obvious discomfort.(2) Intubation of0.9%saline multislice CT imaging of the small intestine to moderate expansion of the intestine. The small intestine in29patients with an average filling score was2.82points, the jejunum average filling score of2.5points, ileum average filling score of2.75points.23cases of dilation was3Level, four cases of expansion was2Level, two cases of expansion was1Level. The29patients of luminal distention of jejunum was20.5±3.6mm, ileum was19.0±3.2mm. Jejunum and ileum intestinal distension was no significant difference (P>0.05).(3)Five cases of intubation multislice spiral CT enterography were treated according to the diagnosis of small bowel tumors, active Corhn's disease7cases,2cases of intestinal tuberculosis, one cases of other diseases,14cases of abnormal findings (including two case of false negative).(4) For the intubation multislice spiral CT enterography in the diagnosis of intestinal diseases, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were88.2%,100%,93.1%,100%and85.7%, respectively.Conclusions:(1) As0.9%saline and the normal plasma, tissue fluid with the same osmotic pressure values,0.9%saline can be used as the small intestine negative CT contrast agent.0.9%saline can be a good expansion of the small intestine and showed wall, can be used as a reasonable choice of contrast agent with lesions of the small intestine, without increasing the patient's condition.(2) The intubation MSCT of small bowel with0.9%saline can make the bowel luminal adequate distention, may be feasible to find and display the intestinal lesions, with high sensitivity, specificity and accuracy.
