摘　　要：目的:探讨MSCT对肠石性肠梗阻的临床应用价值。方法:对23例经手术或临床诊断证实的肠石性肠梗阻的MSCT及多平面重组(MPR)资料进行回顾性分析,着重于定性与定位诊断、并发症与合并症的显示,并与手术所见对照。结果:15例经手术证实的病例定位诊断均正确;21例(21/23)定性诊断正确,"气泡征"(22/23)与"瓶塞征"(21/23)为肠石性肠梗阻的最典型CT表现,1例对合并症的定性诊断不确定,1例遗漏合并症;2例显示肠穿孔。结论:MSCT结合MPR对肠石性肠梗阻的定位定性诊断、对其并发症及合并症的显示具有重要的临床应用价值。Objective：To evaluate the value of multi-slice CT （MSCT） in the clinical application of intestinal bezoar obstruction. Methods：All of 23 patients with bezoar obstruction of intestine proved by surgery or clinical diagnosis had MSCT examination and multi-planar reformation （MPR）, the imaging materials were reviewed retrospectively,mainly concerned at the efficacy of CT in the diagnosis and localization as well as illustration of complication. The imaging manifestations were correlated with surgical findings. Results：Of the 15 patients underwent surgery proved to have correct localization diagnosis, 21 cases （21/23） had correct characteristic diagnosis showing typical ＂bubble sign＂ （22/23） and ＂stopper sign＂ （21/23） of intestinal benzoar obstruction on CT. 2 cases showed complicated intestinal perforation, yet 1 case didn＇t have definite CT features of complication and another case with complication was missed. Conelusion：MSCT in combination with MPR showed important clinical value for the diagnosis of localization, characterization as well as demonstrating complication of intestinal benzoar obstruction.
