目的：探讨使用多层螺旋 CT 瘘道造影三维重建技术对复杂性肛瘘进行诊断的临床应用价值。资料与方法：收集经手术证实的24例复杂性肛瘘患者，经皮下瘘口注入30%泛影葡胺水溶液后，行多层螺旋 CT 横断面扫描及计算机 SSD、VRT、 MPR 后处理，测量病灶长度与宽度，并明确其数目及走行方向。结果：以多层螺旋 CT 瘘道造影横断面图像信息为基础并结合 MPR 冠矢状位、SSD 、VRT 图像观察，能显示宽窄不一、走行方向不同、形态各异的瘘管及分支，并明确内口位置及其与周围组织的解剖关系。结论：利用多层螺旋 CT 的优良性能并结合瘘道造影，可直观展示复杂性肛瘘，从而为手术方案制定及术后观察提供科学依据。

Objective : To study the applied value of MSCT three dimensional reconstruction image combined with MSCT fistulography in complex anal fistula. Methods : To review 24 cases of complex anal fistula confirmed by operation. Al the patients were scanned after injected contrast medium through the fistula canales.then performed restruction by MPR (multi planar reformation) , SSD (shaded surface display) and VRT(volume rendering technology),measured length and width of lesions, identified sum and site of lesions.Result: On routine sectional view of MSCT fistulography combined with image of restruction, the shape and the branch of fistula can be displayed wel , the correlation between anal fistula and surrounding tissue can be revealed, the site of inner orificium can be showed accurately.Conclusion:MSCT combined with fistulography can display complex anal fistula directly , thus it is a reliable method for operative guidance.
