目的研究一种新的、简便易行的小肠双对比造影法——无管法快速小肠气钡双对比造影法。方法将产气粉装入小肠溶胶囊,口服并在小肠内崩解,释放二氧化碳气体,配合口服钡剂及西沙必利,形成小肠双对比像。选取130例拟行小肠造影检查者,随机分为研究组和对照组,研究组67例采用本法,对照组63例采用口服钡剂法加肌注胃复安。结果研究组53例效果满意,12例基本满意,2例未观察到明显双对比效果,其中1例因吞咽困难无法检查,总有效率97.02%,平均检查时间(34.63±16.66)m in;对照组均为单钡造影效果,平均检查耗时(77.12±32.98)m in;2种检查方法耗用时间及2种药物的效果在统计学上具有显著性差异(P<0.01)。结论无管法快速小肠气钡双对比造影法确能形成良好的气钡双对比像,小肠观察效果较口服钡剂法有明显提高。
Objective To study a new, simple and easy method of small bowel double contrast angiography - tubeless rapid small intestine barium double contrast angiography. Methods Producing gas powder into small intestine capsule, orally and disintegrating in the small intestine, releasing carbon dioxide gas, with oral barium and cisapride to form double contrast image of small intestine. Selected 130 cases of intestine small bowel examination, were randomly divided into study group and control group, 67 cases in the study group using this method, the control group of 63 patients with oral barium method plus intramuscular injection of metoclopramine. Results The study group was satisfied with the results of 53 cases, 12 cases were basically satisfied, 2 cases did not observe significant double contrast effect, 1 case was unable to check due to dysphagia, the total effective rate was 97.02%, the average examination time (34.63 ± 16.66) The results of single barium radiography were the same as those of the control group (average 77.12 ± 32.98) mins. The time spent on the two methods and the effect of the two drugs were statistically significant (P <0.01). Conclusions Tubeless double-contrast barium-fast contrast gas contrast can indeed form a good contrast between barium and barium, and the effect of small intestine is obviously improved compared with that of oral barium.
