高频彩色多普勒超声诊断肛周脓肿的体会

Experience of high frequency color Doppler ultrasound in the diagnosis of perianal abscess

目的:探讨高频超声对肛周脓肿的诊断价值及超声诊断规律。方法:对56例肛周脓肿患者的临床资料和声像图表现进行回顾性分析。结果:超声能显示脓肿的范围、位置、液化情况、脓肿分期以及是否合并肛瘘;超声诊断肛周脓肿符合率98.2%(55/56),误诊率1.8%(1/56),肛瘘诊断符合率80%(4/5);对造成漏、误诊的原因进行了分析。结论:高频超声对肛周脓肿诊断有较高的临床应用价值,是肛周脓肿的首选检查方法,可以为临床诊断和治疗提供重要依据。

Objective:To explore the diagnostic value and ultrasonic diagnosis regularity of high frequency ultrasound for perianalabscess.Methods:The clinical data and ultrasonographic manifestations of 56 patients with perianal abscess were retrospectivelyanalyzed.Results:Ultrasonography showed the range,location,liquefaction of abscess,abscess stage and whether with anal fistula.The coincidence rate of ultrasound diagnosis of perianal abscess was 98.2% (55/56),the misdiagnosis rate was 1.8% (1/56).Thecoincidence rate of perianal abscess diagnosis was 80% (4/5).The causes of misdiagnosis and missed diagnosis were analyzed.Conclusion:High frequency ultrasound has a high clinical application value in the diagnosis of perianal abscess.It is the firstchoice examination method of perianal abscess,and can provide an important basis for the clinical diagnosis and treatment.
