摘  要:目的 探讨多层螺旋CT在胆石性肠梗阻诊断中的价值.方法 回顾分析15例经手术证实的胆石性肠梗阻病例的临床及影像资料.15例均行全腹部CT平扫、X线腹部平片和腹部超声检查.结果 多层螺旋CT显示肠梗阻共15例,不完全性小肠梗阻12例,完全性肠梗阻3例;异位结石15例,其中9例位于回肠,4例位于空肠, 1例于胆囊内及回肠内均可见结石,1例于胆囊-十二指肠瘘口及回肠内各见一结石;胆囊积气15例,胆道积气13例;胆囊窝结构紊乱15例,其中6例MPR图像清晰显示胆囊-十二指肠瘘.多层螺旋CT的诊断准确率可达100%.结论 多层螺旋CT在胆石性肠梗阻的定位和定性诊断中具有重要价值,为手术方案的制订提供影像学信息.Objective To evaluate the vaue of multi--slice spiral CT(MSCT) in the diagnosis of gallstone ileus. Methods The clinical and radiological data of fifteen patients with gallstone ileus proved by surgery were reviewed. MSCT,abdominal radiography and US were performed in all patients. Results MSCT showed intestinal obstruction in all cases,including incomplete small--bowel obstruction in 12 cases and complete obstruction 3 cases. Other findings included ectopic stone in 15 cases, of which 9 cases in the ile- um, 4 cases in the jejunum, 2 patients with stones both in the gallbladder (or gallbladder-- duodenal fistula) and the ileum,pneumo --gallbladder in 15 cases, pneurnobilia in 13 cases and gallbladder fossa structural disorder in 15 cases, of them, gallbladder -- duo- denal fistulas were clearly showed in 6 cases by MPR images. The diagnostic accurate rate was 100% by MSCT. Conclusion MSCT is valuable for diagnosing gallstone ileus, which can provide more information for the surgical plan.
