摘　　要：目的探讨多层螺旋 CT(MSCT)瘘管造影在肛瘘中的临床应用价值。方法回顾性分析经手术证实的28例肛旁脓肿及肛瘘患者,通过 MSCT 进行瘘管造影检查,并进行影像学评价。结果28例患者中8例为肛旁脓肿,20例患有肛瘘。20例肛瘘中,复杂性肛瘘16例,单纯性肛瘘4例;多平面重组(MPR)技术准确显示18例瘘管内口。结论 MSCT 瘘管造影检查在肛瘘检查中有较高的应用价值,MPR 对内口的显示对临床治疗方案的制定有重要价值。Objective To evaluate the clinical application of the fistulography of multi-slice spiral CT（MSCT） in the diagnosis of anal fistula. Methods A total of 28 patients who were verified operatively of fistula in ano underwent preoperative fistulography of MSCT. The multi-planar reformation （MPR） and surface shadow display （SSD） images were generated and analyzed retrorespectively. Results There were 8 cases with perianal abscess and 20 cases with anal fistula in 28 patients. Complex fistula was diagnosed in 16 cases, and simple inter-sphincteric fistula was found in 4 cases ; the inner orificiums of anal fistulas were revealed accurately with MPR images in 18 cases. Conclusion The fistulography of MSCT is valuable for preoperative assessment of anal fistula, in particular for investigation of the inner orificiums of anal fistulas with MPR.
