摘　　要：目的探讨螺旋CT对消化道梗阻的诊断价值。方法回顾性分析了12例临床怀疑为消化道梗阻病例的螺旋CT检查结果并将其中螺旋CT确诊为消化道梗阻病例与临床结果对照,图像重建方法主要为多平面重建法(MPR)和最大密度投影法(MIP)。结果44例患者,无肠梗阻2例,有肠梗阻42例,其中33例经手术病理证实,4例经临床确诊。33例手术病例CT诊断梗阻部位与手术对照符合率为100%(33/33),病因诊断符合率为100%(33/33)。结论螺旋CT扫描及重建对消化道梗阻具有重要诊断价值。Objective To discuss the diagnostic value of spiral computed tomography （CT） in digestive tract obstruction. Methods 44 cases suspected with digestive tract obstruction underwent MDCT. 33 cases of them in the diagnostic results of MDCT were compared with the surgical and pathological findings. The main reconstracfion method included multi-planar reconstruction （MPR） and maximum /ntensity projection （MIP）. Results Among 44 cases, 33 cases were confirmed by postoperative pathology. To comparing with the results of surgery, the localization diagnosis was correct in 33 patients（100%） and the pathogenic diagnosis was correct in 33 patients（100%）. Conclusion Spiral CT has an important value in the diagnosis of digestive tract obstruction.
