目的探讨经直肠360°腔内超声诊断肛周脓肿的应用价值。方法对57例可疑肛周脓肿患者进行经直肠360°腔内超声检查,根据病灶的部位及声像特征分为4种类型,并与手术及病理结果对照。结果经直肠360°腔内超声对肛周脓肿分型诊断结果与手术结果一致性检验的Kappa值为0.873(P<0.01),对内口的诊断准确率为91%(31/34)。脓肿的声像表现为不均匀低回声,内口的声像表现为黏膜局部连续性中断或局部膨隆改变。结论经直肠360°腔内超声能准确诊断肛周脓肿及分型,可为临床治疗方案的制定提供有益的帮助。
Objective To investigate the value of 360 ° transrectal ultrasound in the diagnosis of perianal abscess. Methods Totally 57 cases of suspected perianal abscess were subjected to 360 ° transrectal ultrasonography, which were classified into 4 types according to the location of the lesion and the features of the acoustic image. The results were compared with the results of surgery and pathology. Results The Kappa value was 0.873 (P <0.01) and 91% (31/34), respectively, for the diagnosis of perianal abscess by intrarectal 360 ° EUS. Abscess showed hypoechoic hypoechoic, intraoral mucosal performance of the local continuity of the interruption of disruption or local bulging changes. Conclusion The transrectal 360 ° intra-uterine ultrasound can accurately diagnose perianal abscess and classification, which can provide useful help for the development of clinical treatment plan.
