To Explore the Experience of Clinical Application of Multislice CT Enterography With Oral Isotonic Mannitol

目的浅谈口服等渗甘露醇多层螺旋CT小肠造影(MSCTE)的临床应用体会。方法 150例疑似小肠病变的患者口服2.5%甘露醇约2 000 ml,肌注山莨胆碱10 mg后行多层螺旋CT三期扫描,结合多平面重建(MPR)、最大密度投影(MIP)和容积重建技术(VRT)观察肠腔、肠壁、肠系膜血管及肠周情况。结果阳性43例(小肠淋巴瘤3例,间质瘤6例,小肠腺癌6例,克罗恩病6例,肠结核2例,肠扭转2例,小肠憩室1例,空肠出血1例,粘连性肠梗阻6例,小肠息肉并肠套叠1例,小肠淋巴管扩张1例,肠梗阻8例),余为正常组。结论口服等渗甘露醇多层CT小肠造影可以明显提高小肠疾病的诊断能力,在定位、定性方面有较高的临床价值。

Objective To discuss the clinical value of multislice CT enterography（MSCTE） with oral isotonic mannitol. Methods Selected 150 patients suspected of small intestinal disease were examined, which were oral 2.5% isotonic mannitol about 2 000 ml and then 10 mg of anisodamine was injected intramuscular. Helical CT scanning was performed 10 minutes later, observes the enteric cavity, intestinal wall, bowel mesenteric vessels and intestinal peripheral with MPR, MIP and VRT. Results Small intestinal lymphoma in 3 cases, 6 cases of stromal tumor, 6 cases of small intestinal carcinoma, 6cases of crohn＇s disease, intestinal tuberculosis in 2 cases, volvulus in 2 cases, small intestine diverticulum in 1case, 1 case of jejunal bleeding, adhesion ileus 6 cases, small intestine polypus and intussusception in 1case, small intestinal lymphangiectasia in 1 case, 8 cases intestinal obstruction, the rest negative. Conclusion MSCTE was valuable for intestinal disease in terms of positioning and qualitative.
