摘　　要：目的探讨经腔道超声造影(IC-CEUS)用于诊断瘘的价值。方法回顾性分析2009年6月至2012年7月在中山大学附属第三医院超声科先后接受常规超声检查(CUS)、IC-CEUS,经X线瘘管造影或手术证实的20例瘘患者临床资料。所有患者均签署知情同意书,符合医学伦理学规定。其中男14例,女6例;年龄17～77岁,中位年龄56岁。分别计算CUS和IC-CEUS对瘘的诊断符合率。两种方法的诊断符合率比较采用χ2检验。结果 20例患者中,CUS确诊瘘5例,但未能明确定位瘘管,诊断符合率为25%(5/20)。IC-CEUS确诊瘘18例,均能明确定位瘘管,诊断符合率为90%(18/20)。IC-CEUS对瘘的诊断符合率明显高于CUS,差异有统计学意义(χ2=17.289,P<0.05)。结论相对于CUS检查,IC-CEUS对瘘有较高的检出能力,有可能成为诊断瘘的重要影像学手段之一。Objective To investigate the value of intracavitary contrast-enhanced ultrasound （IC-CEUS） in the diagnosis of fistulas. Methods Clinical data of 20 patients in Department of Medical Ultrasonics, the Third Affiliated Hospital of Sun Yat-sen University from June 2009 to July 2012 were enrolled in the study for retrospective analysis. The patients underwent examinations of conventional ultrasound （CUS） and IC-CEUS, and were confirmed with fistulas by X-ray fistulogram or operation. The informed consents of all patients were obtained and the ethical committee approval was received. There were 14 males and 6 females with age ranging from 17 to 77 years old and median age of 56 years old. The diagnostic coincidence rates of fistulas by CUS and IC-CEUS were calculated respectively. And the difference between two methods was compared by Chi-square test. Results Five fistulas were detected by CUS with the diagnostic coincidence rates of 25% （5/20）, while the fistulas could not be located exactly. Eighteen fistulas were detected by IC-CEUS with the diagnostic coincidence rate of 90% （18/20） and all the fistulas could be located exactly. The diagnostic coincidence rate of IC-CEUS was evidently higher than that of CUS. There was significant difference between two methods（χ2=17.289,P〈0.05）. Conclusions IC-CEUS has higher detective ability for fistulas than CUS and it could be one of the important imaging means in the diagnosis of fistulas.
