经阴道或会阴超声端扫式凸阵探头定位女性肛瘘内口

Transvaginal or perineal ultrasound end-scan convex array probe in localization of internal orifice of female anal fistula

目的探讨经阴道或会阴超声端扫式凸阵腔内探头定位女性肛瘘内口的价值.方法对17例肛瘘患者(病例组)和15名对照组女性于术前采用频率3~10MHz端扫式凸阵腔内探头检查肛瘘内口,术后与手术结果相对照.结果所有患者均能耐受检查.病例组17例共18个肛瘘内口,术前超声发现16个,超声诊断符合率为88.89%(16/18);对照组均能清楚显示肛管三层结构.结论经阴道或会阴超声端扫式腔内探头定位女性肛瘘内口临床价值较高.

Objective To explore the value of transvaginal or perineal ultrasonography end-scan convex array probe in localization of internal orifice of female anal fistula.Methods Seventeen patients with anal fistulas (case group) and 15 women in control group were examined with 3-10 MHz end-scan convex array ultrasound probe before operation,and the findings were compared with surgical results.Results All subjects could tolerate ultrasonic examinations.There were totally 18 anal fistula internal orifices among 17 patients in case group,among which 16 were found with ultrasound before operation,and the coincidence rate of ultrasonic diagnosis with surgical operation was 88.89%(16/18).In control group,three-layer structure of anal canal could be clearly displayed.Conclusion Transvaginal or perineal ultrasonography end-scan convex array probe has high clinical value in localization of internal orifice of female anal fistula.
