直肠腔内高频环形超声对肛周脓肿的诊断价值分析

Value Estimation of High-frequency Ring-like Ultrasound in Rectal Cavity for Diagnosing Perianal Abscess

为探讨直肠腔内高频环形超声诊断肛周脓肿的价值,选取2017年1月至2018年1月于我院接受治疗的60例肛周脓肿患者进行研究,患者均采用直肠腔内高频环形超声和线阵高频超声探头对患者进行诊断,随后进行手术治疗。将2种超声诊断结果与手术确诊结果进行对比。结果显示,手术确诊低位肛周脓肿34例,高位肛周脓肿26例。线阵高频超声诊断低位肛周脓肿39例,高位肛周脓肿21例。高频环形超声诊断低位肛周脓肿34例,高位肛周脓肿26例。高频环形超声诊断高位肛周脓肿诊断的敏感度、特异度均高达100%,明显高于线阵高频超声的敏感度80.77%,差异有统计学意义,P <0.05。经一致性分析显示,高频环形超声检查κ值为0.813±0.147,高于线阵高频超声0.599±0.129,差异有统计学意义,P <0.05。结果表明,与线阵高频超声相比,直肠腔内应用高频环形超声能够更准确地诊断各型肛周脓肿,对于高位肛周脓肿、复杂性肛周脓肿的显示更清晰,定位更准确,优势明显。

This study was to explore the diagnosis value of high-frequency ring-like ultrasound in rectal cavity for perianal abscess（PA）,enrolled 60 cases of PA who were to he subject to treatment in author＇s hospital（2017-01--2018-01） in the study, they all received high-frequency ring like ultrasound inspection and linear array high-frequency probe to diagnose PA,followed by surgery; then compared the two ultra- sound diagnostic results and the confirmed diagnosis by operation. As results, the confirmed diagnosis by operation,linear array high-frequency probe diagnosed results, and high frequency ring-like ultrasound di- agnosed results were respectively as：low PA 34 cases, high PA 26 cases;low PA 39 cases, high PA 21 ca- ses;low PA 34 cases,high PA 26 cases,so there was statistical difference between high-frequency ring-like ultrasound and linear array high frequency probe（100%,100% vs 80.77%, P 〈0.05） in diagnostic sensi- tivity and specificity; Also, identity analysis showed the former was significantly higher than the latter [（0.813±0.147） vs （0.599±0.129）, P 〈0.05] in k value.Results show that high-frequency ring-like ultra- sound in rectal cavity can more accurately diagnose all types of PA,more clearly display and more accurate- ly locate the high and complex PA,which has obvious advantages.
