摘要
目的探讨实时三维超声在肛瘘内口立体定位、显示瘘管走形中的应用价值。方法采用常规二维超声和实时三维超声检查118例肛瘘患者，对肛瘘进行内口立体定位，对瘘管走形进行跟踪观察，并与手术及病理相对照。结果术前肛瘘内口的二维超声诊断准确率为85％（100／118），三维超声诊断准确率为95％（112／118），三维超声诊断肛瘘内口准确率显著高于二维超声（x2=6．679，P〈0．05）。三维超声诊断复杂性肛瘘主管准确率100％（82／82）高于二维超声95％（78／82），差别有统计学意义（x2=4．100，PdO．05）；二维超声诊断复杂性肛瘘支管准确率为70％（57／82），三维超声为89％（73／82），差别有统计学意义（x2=9．499，PdO．05）。结论三维超声能更清晰地显示肛瘘内口的位置，准确定位内口及判断瘘管的走向，为临床提供更直观的资料，具有较高的实用价值。
Objective To evaluate the clinical value of the real-time three-dimensional ultrasound in the diagnosis of the fistula-in-ano. Methods One hundred and eighteen fistula-in-ano patients were examined using conventional and three-dimensional ultrasound, the stereotaxis of interal opening and the shape of the fistula-in-ano were analyzed. Then the diagnosis results of ultrasound were compared with the surgery and pathology. Results In 118 patients,the accuracy of preoperative identifying internal opening by two-dimensional ultrasound was 85%, and 95% for three-dimensional ultrasound with statistically significant difference （X2 = 6.679, P 〈0.05）. For complex anal fistula, the diagnostic accuracy rates of main fistula tract by three-dimensional ultrasound （100%, 82/82） was higher than that by two-dimensional ultrasound（95% ,78/82）,the difference was statistically significant （X2 = 4.100, P 〈0.05）. In 82 cases of complex anal fistula, the diagnostic accuracy of branch fistula tract by two-dimensional ultrasound was 70% （57/82）, the accuracy using three-dimensional ultrasound was 89% （73/82）, there was statistically significance （X2 = 9.499, P 〈0.05）. Conclusions Three-dimensional ultrasound can accurately locate the interal opening of fistula-in-ano and determine the shape of fistula-in-ano,which provided the most intuitive information for clinical treatment and had high practical value.
