克罗恩病肛瘘(肛周脓肿)MRI影像分析

目的分析总结克罗恩病(CD)肛瘘(肛周脓肿)患者肛周MRI影像学分布特点及Van Assche MRI评分的相关指标.方法回顾性分析2012年12月至2019年9月27例行肛周MRI检查的CD肛瘘(肛周脓肿)患者的临床资料.将Van Assche MRI核磁瘘管评分与CRP及PCDAI进行相关性分析.结果27例瘘管中,86.8%的瘘管位于肛门内外括约肌间隙.Van Assche MRI评分与CRP及PCDAI无相关性.结论CD肛瘘位置可能更易发生在肛门括约肌间隙,通过肛门括约肌间隙向上或肛门向外延伸,为临床手术医师提供一定的参考.核磁影像学中瘘管炎症指标与CRP及PCDAI无相关性.

Objective To analyze and summarize the perianal MRI distribution characteristics and relevant indicators of Van Assche MRI score in anal fistula(perianal abscess)in patients with Crohn's disease.Methods Retrospectively analyzing December 2012 to September 2019,27 Crohn's disease patients with MRI scans were included.The correlarion between Van Assche MRI and CRP and PCDAI were analyzed.Results 86.8% fistula were located in intersphincteric space in perianal CD fistulas(abscess).The correlation between nuclear magnetic fistula score and CRP and PCDAI showed no significant correlation.Conclusion Perianal CD fistulas(abscess)are tended to occurs in intersphincteric space,extending upward or outward through the intersphincteric space.It provides certain reference value for the clinical surgery doctors.There is no correlation between CRP or PCDAI with Van Assche MRI.
