摘要
【目的】评价口服大剂量5%等渗甘露醇螺旋CT小肠造影（spiral CT enterography,SCTE）在小肠肿瘤诊断中的价值。【方法】36例小肠肿瘤患者每人口服约1000-1500 mL 5%等渗甘露醇后,肌注20 mg山莨菪碱注射液,10-15 min后行螺旋CT三维扫描,分析不同小肠肿瘤的SCTE表现,并比较42例传统CT扫描与SCTE的诊断结果。【结果】36例SCTE患者除2例回盲部充盈欠佳外,余病例十二指肠、空肠及回肠肠腔充盈良好,对肿瘤的显示、衬托满意。SCTE检查与临床诊断符合率为94.4%（34/36）,高于传统CT扫描78.57%（33/42）（χ^2=4.03,P〈0.05）。【结论】SCTE是一种简便、安全、非侵袭性、有效评价小肠肿瘤的方法,能明显提高肿瘤的检出率。
[Objective] To study the value of spiral CT enterography （SCTE） with orally administering large dosage of 5% isosmotic mannitol as negative contrast in the diagnosis of small intestine tumor. [Methods]Thirty six cases of small intestinal tumor were examined. About 1000- 1500 mL 5% isosmotic mannitol as oral negative contrast agent was administered and then 20mg Raceanisodamine hydrochloride was injected intramuscularly. Spiral CT scanning in three phases was performed 10 to 15 minutes later. Demonstration features of various kinds of small bowel tumors were analyzed by comparing with the results of conventional CT scan in 42 patients, and the diagnostic efficacy of SCTE was evaluated. [Results]Except two cases had unsatisfactory results in filling ileocecal junction, all the other cases had satisfactory results in filling the duodenum,jejunum,ileum and in demonstrating the bowel tumors by SCTE. The clinical diagnostic coincidence of SCTE was 94.4%（34/36） ,which was higher than that by conventional CT（78.57%, 33 /42）. The difference between two modalities was significant（χ^2=4.03, P〈0.05）. [Conclusion] SCTE with isosmotic mannitol as negative contrast for distending the small bowel is a simple, rapid, safe, noninvasive and effective method for evaluating small bowel tumor. It can obviously increase the detectability of small intestine tumors.
