摘要
目的探讨经静脉超声造影联合经瘘管超声造影在肛瘘诊断中的应用价值。方法回顾性选取2018年1月至2019年6月中国科学院大学宁波华美医院肛肠外科收治的79例肛瘘患者,在常规二维超声检查的基础上分别行经静脉和经瘘管双重超声造影检查,记录外口的数目、位置、距肛缘的水平距离,瘘管的走行、与括约肌和肛提肌的关系(Parks分类),内口的数目、位置、距肛缘的垂直距离,分支瘘管的数目、走行,与手术诊断结果作对照分析。结果双重超声造影诊断肛瘘Parks分类的准确性高于常规二维超声检查(92.41%vs 79.75%),差异有统计学意义(χ2=5.247,P=0.022)。双重超声造影诊断肛瘘内口和分支瘘管数目的准确性分别为92.79%、85.71%,常规二维超声诊断内口和分支瘘管数目的准确性分别为76.58%、62.86%,差异均有统计学意义(χ2=11.202、4.718,P=0.001、0.030)。结论双重超声造影检查可充分发挥超声造影技术的优势,对肛瘘的Parks分类、内口及分支瘘管的判断具有较高的准确性,可弥补常规二维超声的不足,为临床治疗决策提供依据。
Objective To assess the clinical value of dual contrast-enhanced ultrasound(DCEUS)in diagnosing anal fistula.Methods Seventy-nine patients with anal fistula who received ultrasonography and DCEUS examination at the Department of Anorectal Surgery,Hwa Mei Hospital,University of Chinese Academy of Sciences from January 2018 to June 2019 were retrospectively selected.We recorded below parameters:the number and position of fistulous external openings and the distance between fistulous external opening and anal edge;fistulous track and its positional relation with levator ani muscle and sphincter(Parks classification);the number and position of fistulous internal openings and the distance between fistulous internal opening and anal edge;and the track and number of fistulous branches.Then we compared these parameters with surgical diagnosis.Results The accuracy rates of DCEUS and ultrasonography in diagnosing the Parks classification(92.41%vs 79.75%,χ2=5.247,P=0.022),internal openings(92.79%vs 76.58%,χ2=11.202,P=0.001),and branches(85.71%vs 62.86%,χ2=4.718,P=0.030)differed signficantly.Conclusion DCEUS examination is increasingly playing a significant role in ultrasound diagnosis.It has high accuracy in the diagnosis of the Parks classification,the internal openings,and the branches of anal fistulas.
