摘　　要：目的:探讨MSCT对肠石性肠梗阻的诊断价值。方法:回顾性分析17例经手术证实的肠石性肠梗阻的CT表现。结果:17例患者中共有结石23枚。肠梗阻17例(17/17),肠石形态为类圆形6枚,长条状10枚,不规则型7枚,均表现为小肠粪球征。9枚位于上消化道,14枚位于下消化道。1例伴有肠系膜旋转。3例伴有肠系膜密度增高。6例肠壁增厚,3例增强肠壁强化减弱。3例伴有腹水。结论:MSCT具有较高的密度分辨率及空间分辨率,结合多平面重组(MPR)及临床资料,可以对肠石性肠梗阻作定性、定位诊断。Objection：To evaluate the value of multi-slice CT （MSCT）in the diagnosis of intestinal obstruction due to enterolith.Methods：The MSCT manifestations of 17 cases with surgery proven intestinal obstruction due to enterolith were retrospectively analyzed.Results：Totally,there were 23 enteroliths in these 17 intestinal obstruction patients.All patients had ileus （17/17 cases）.The shape of enterolith was oval （n=6）,long （n=10）,irregular （n=7）,showing honeycomb pat-tern with air bubbles inside （n=23）.The location of enterolith included upper GI tract （n=9）and lower GI tract （n=14）. Mesenteric volvulus was seen in 1 case.3 patients showed hyper-attenuation of mesentery,6 patients had intestine wall thickening,3 patients showed reduced enhancement of bowel wall after contrast administration.Ascitis could be seen in 3 ca-ses.Conclusion：MSCT has high spatial and contrast resolution,when accompanied with multi-planar reformation （MPR） technique and correlated with clinical materials,qualitative diagnosis and accurate localization of intestinal obstruction caused by enterolith could be made.
