【摘要】：目的探讨实时三维超声在肛瘘内口定位、术前评估和指导手术中的应用价值。资料与方法回顾性分析经手术确诊为肛瘘的142例患者的超声资料,术前均行二维超声和三维超声检查,分析三维超声图像特征及诊断肛瘘的分型与准确率,比较二维超声与三维超声诊断肛瘘内口位置、瘘管主管及支管走行的准确率。结果142例患者中,低位单纯性肛瘘25例,低位复杂性肛瘘15例,高位单纯性肛瘘20例,高位复杂性肛瘘82例。三维超声对肛瘘不同分型诊断准确率均为100.0%。三维超声诊断肛瘘内口、主管、支管准确率分别为95.0%(135/142)、100.0%(97/97)、90.7%(88/97),与二维超声的82.3%(117/142)、93.8%(91/97)、69.0%(67/97)比较,差异均有统计学意义(P0.05、P0.01)。结论三维超声能准确定位肛瘘内口,清晰显示瘘管整体的空间形态,提供比较直观的瘘管的空间结构,是诊断肛瘘的有效辅助检查方法,具有较高的临床实用价值。
[Abstract]:Objective to evaluate the value of real-time three-dimensional ultrasound in the localization of internal orifice of anal fistula, and to evaluate and guide the operation before operation. Materials and methods the ultrasonographic data of 142 patients with anal fistula confirmed by operation were retrospectively analyzed. Two-dimensional ultrasound and three-dimensional ultrasound were performed before operation. The characteristics of three-dimensional ultrasound images and the classification and accuracy of diagnosis of anal fistula were analyzed, and the location of internal anal fistula was compared between two-dimensional ultrasound and three-dimensional ultrasound. Results among 142 patients, there were 25 cases of low simple anal fistula, 15 cases of low complex anal fistula and 20 cases of high simple anal fistula. There were 82 cases of high complex anal fistula. The accuracy of three dimensional ultrasound in the diagnosis of different types of anal fistula was 100.00.The accuracy of three dimensional ultrasound in the diagnosis of anal fistula internal cavity, supervisor and branch canal was 95.00.05 / 142, 100.097 / 97 / 90.788 / 97 / 97 respectively, compared with 82.33.3 / 93. 891 / 97 / 93. 891 / 97 / 99.97 / 97 of two-dimensional ultrasound. Conclusion Three-dimensional ultrasound can accurately locate the internal orifice of anal fistula, clearly display the spatial form of fistula, provide a more intuitive spatial structure of fistula, and is an effective auxiliary examination method for the diagnosis of anal fistula. It has high clinical practical value.
