摘　　要：目的探讨不拔除保留灌肠管时,磁共振成像(MRI)检查对肛瘘内口识别的重要性。方法收集54例临床诊断为肛瘘且经手术治疗的患者,行MRI平扫、动态增强扫描(未拔除保留灌肠管)及延迟增强扫描(拔除保留灌肠管),分别计算拔除保留灌肠管前后MRI对肛瘘内口诊断的准确率。结果与术中所见比较,拔除保留灌肠管前后增强MRI扫描对内口诊断的准确率分别为91%、79%,差异有统计学意义。结论结合不拔除保留灌肠管,MRI检查对肛瘘内口有较高的诊断准确率,可以为临床提供更准确、更全面信息。Objective To investigate the importance of retention enema tube kept in place for identifying the internal opening of anal fistula during MRI examination.Methods Included in this study were 54 patients with clinically diagnosed anal fistula to be treated with surgery.The patients underwent MRI plain scan,dynamic enhanced scan(with retention enema tube unremoved),and delayed enhanced scan(removed of the retention enema tube).The accuracy of MRI in identifying the internal opening of anal fistula before and after removal of retention enema tube was calculated.Results According to the findings prior to surgery,the accuracy of the two enhanced MRI scans before and after removal of the retention enema tube was 91%and 79%,respectively,with statistically significant difference.Conclusion MRI examination with the retention enema tube kept in place yields higher accuracy in identifying the internal opening of anal fistula,thereby providing more accurate and comprehensive information for the clinical practice.
