肛瘘造影方法的改进

Improvement of Radiography of Anal Fistula

【目的】探索通过使用Ⅱ型血管造影用鞘组，提高肛瘘造影的成功率。【方法】本课题收集24例择期肛瘘手术病人行肛瘘造影，病例从2005年1月至2008年10月，病人均为初次手术，造影前局麻、扩肛，探针适度扩张瘘管，设置齿线标记，使用Ⅱ型血管造影用鞘组造影。【结果】17例造影成功者手术均获成功，术后无复发，造影失败7例手术后复发1例，复发率4．17％。造影成功率达70．8％。【结论】使用II型血管造影用鞘组，造影前局麻、扩肛，探针适度扩张瘘管，设置齿线标记，能提高造影成功率，降低术后复发率。

[Objective] To explore the use of radifocus introducer II so as to raise the achievement ratio of radiography of anal fistula. [Methods]Twenty four cases of anal fistula selected from Jan. 2005 to Oct. 2008 were all first operation. All patients were locally anesthetized, and underwent anus dilation and moderate fistula dilation with probe before radiography. The symbol of tooth trace was installed. Then radifocus introducer II was used for radiography. [ResultslSeventeen cases with successful radiography were operated successfully, and there was no recurrence after operation, while one of 7 cases with abortive radiography was recurred after operation （4.175）. The achievement ratio of radiography of anal fistula in experimental group was 70.80%（17/27）. [Conclusion]When local anesthesia, anus dilation and moderate fistula dilation with probe are done before radiography and the symbol of tooth trace is installed, radifocus introducer II can raise the achievement ratio of radiography of anal fistula and decrease the recurrence rate of post-operation.
