目的探讨三维直肠腔内超声诊断肛周脓肿病理时期、分型,显示内口的应用价值。方法选取我科收治的肛周脓肿患者110例作为研究对象,收集患者应用三维直肠腔内超声检查数据,在三维立体模块中根据声像图特征进行区分肛周脓肿病理时期、分型、定位内口,显示内口、脓腔的上下缘距肛缘的距离。结果三维直肠腔内超声确诊肛周脓肿110例,与手术对比,病理分期准确率98%(108/110),分型100%;定位内口82例,准确率74%(82/110)。结论应用三维直肠腔内超声检查肛周脓肿,能够准确显示脓肿病理时期,判断脓腔类型,定位内口,为临床治疗方法的选择提供有力的影像学依据。
Objective To investigate the application of three-dimensional intra-rectal ultrasound in the diagnosis of perianal abscess pathological stage and sub-type, and to show the value of the inner mouth. Methods A total of 110 patients with perianal abscess admitted to our department were enrolled in this study. The patients were enrolled in this study. The data of three-dimensional intra-rectal ultrasound were collected. The three-dimensional model was used to distinguish perianal abscess, Mouth, showing the mouth, the upper and lower edge of the abscess from the verge of anal margin distance. Results One hundred and three cases of perianal abscess were diagnosed by three dimensional rectal ultrasonography. Compared with the operation, the accuracy of pathological staging was 98% (108/110). The classification was 100%. 82 cases were located in the inner mouth and the accuracy was 74% (82/110). Conclusion The three-dimensional rectal ultrasound examination of perianal abscess can accurately show the pathological stage of abscess, determine the type of abscess, locate the inner mouth, provide a powerful imaging basis for clinical treatment options.
