摘　　要：目的 探讨超声造影术前诊断肛瘘的临床价值.方法 45例初步诊断为直肠肛门瘘患者,术前常规超声检查后经肛瘘外口注入SonoVue,观察瘘管走向和内口开口位置,将超声造影检查结果与手术所见对照.结果 45例患者中单纯性肛瘘19例.常规超声检查17例诊断与手术结果相同,诊断符合率89.5%;造影检查18例诊断与手术结果相同,诊断符合率94.7%,二者比较差异无统计学意义（P＞0.05）.复杂性肛瘘26例,常规超声检查16例诊断与手术结果相同,诊断符合率61.5%,造影检查24例诊断与手术结果相同,诊断符合率92.3%,二者比较差异有统计学意义（P＜0.05）.结论 SonoVue超声造影用于肛瘘术前检查有较高的可视性和准确率,对手术有重要的指导意义.Objective To evaluate the clinical value of contrast-enhanced ultrasound （CEUS） in preoperative diagnosis of anal fistula. Methods Forty-five patients with fistula in ano were evaluated by physical examination, then CEUS were peformed by injecting SonoVue through the external opening to enhance the detection of the fistulous track and the internal opening. The results of CEUS were matched with surgical features to establish their accuracy in preoperative assessment of anal fistula. Results Simple typing fistula was found in 19 of 45 patients and 26 patients had complex fistulas. The accurate diagnostic rates by conventional ultrasound of simple typing fistula and complex fistulas were 89. 5% and 61.5%,respectively,the accurate diagnostic rates by CEUS of simple typing fistula and complex fistulas were 94. 7% and 92.3%, respectively, there was no significant difference between conventional ultrasound and CEUS about simple typing fistula（ P ＞0.05）, and there was significant difference about complex fistulas （ P ＜0. 05）. Conclusions CEUS has a good visibility and accurate rate for diagnosis of anal fistula,It plays an important role for operation.
