【摘要】：目的研究高频彩色多普勒超声对肛周脓肿的诊断评价,为临床治疗提供参考依据。方法选取医院于2014年12月-2015年12月收治的98例肛周脓肿患者,所有患者均行超声检查及直肠指诊,将结果与手术结果及病理结果相比较,同时对肛周感染部位做脓液培养,观察致病菌种类。结果对98例肛周脓肿的脓液培养,共检出病原菌127株,以革兰阴性菌为主,共110株占86.61%;超声在肛周脓肿早期诊断中出现4例漏诊,肛周脓肿形成期出现3例漏诊,超声对肛周脓肿早期的检出率明显低于术后病理检出率(P0.05);超声在单纯型肛周脓肿诊断中出现5例漏诊,复合型肛周脓肿出现2例漏诊,对单纯型肛周脓肿的检出率明显低于手术中发现的肛周脓肿(P0.05);在对98例肛周脓肿的诊断中,超声检查共漏诊7例,直肠指诊漏诊16例,超声检查对肛周脓肿的准确率为92.86%,明显高于直肠指诊法(P0.05)。结论高频彩色多普勒超声对肛周脓肿有较高的诊断准确率,不仅可以对肛周脓肿分型,还可以了解肛周脓肿的大小、分期。
[Abstract]:Objective to study the diagnosis and evaluation of perianal abscess by high frequency color Doppler ultrasound. Methods 98 patients with perianal abscess from December 2014 to December 2015 were selected. The results were compared with the results of operation and pathology. At the same time, the bacterial species were observed by the culture of pus on the site of perianal infection. Results 127 strains of pathogenic bacteria were detected in 98 cases of perianal abscess. Gram-negative bacteria accounted for 110 strains (86.61%). In the early diagnosis of perianal abscess, 4 cases missed diagnosis and 3 cases missed diagnosis during the formation of perianal abscess. The detection rate of ultrasound in the early stage of perianal abscess was significantly lower than that in postoperative pathological diagnosis (P 0.05). In the diagnosis of simple perianal abscess, there were 5 cases of missed diagnosis and 2 cases of compound type of perianal abscess. The detection rate of pure perianal abscess was significantly lower than that of perianal abscess found in operation (P 0.05). Among 98 cases of perianal abscess, 7 cases were missed by ultrasound and 16 cases by rectal finger. The accuracy of ultrasonic examination on perianal abscess was 92.86%. Conclusion High frequency color Doppler ultrasound has a higher diagnostic accuracy for perianal abscess, not only for the classification of perianal abscess, but also for the size of perianal abscess. In stages.

【正文快照】： 直肠肛管周围脓肿(即肛周脓肿),指发生于直肠肛管组织或者周围间隙内受到感染而引起的脓肿,是肛肠外科常见疾病之一[1]。研究发现[2],肛周脓肿多由肛周腺体受到感染,而累及肛周组织,不同的致病菌,引起感染的程度不同,因此对肛周脓肿行病原菌学检查,可以为临床早期治疗提供依据
