摘要
舡瘘是克罗恩病最常见的肛周病变．且多为复杂性肛瘘，治疗困难．复发率高．严重影响患者的生活质量。为了获得最佳的临床疗效．治疗前及治疗过程中精确地进行疾病评估十分重要。影像学检查是评估克罗恩病肛瘘的重要手段，可以明确诊断、准确分型、辅助制定最合适的治疗方案和进行疗效监测。磁共振成像（MRI）和直肠超声内镜（EUS）[或直肠腔内超声（AES）]被认为是评估原发克罗恩病肛瘘的最佳选择，具有较高的特异性和敏感性，而MRI对于监测克罗恩病肛瘘的治疗效果更有优势。瘘管造影由于软组织分辨力较差和有辐射损伤等原因，临床上已经较少应用。本文通过分析各种影像学检查方法及其各自的优势与不足．旨在帮助临床医生为患者选择个体化的最优检查手段。
Anal fistula is the most common perianal lesion in Crohn disease （CD）, which usually is complicated and difficult to treat, and has a high recurrence rate and serious influence on the quality of life of patients. Inaccurate or incomplete intervention may result in irreversible damage. In order to achieve the best outcome, an optimal disease assessment is crucial. Many imaging modalities are useful for the evaluation of perianal fistulas in CD, which may help confirm the diagnosis, accurately classify the disease, plan the most suitable treatment, and monitor the efficacy. Magnetic resonance imaging （MRI）, endoscopic uhrasonography （EUS） and anal endosonography （AES） are considered to be the suitable options for evaluation of the initial perianal fistula, both in terms of sensitivity and specificity, while MR1 is more suitable for monitoring the curative efficacy. Fistulography （by X ray or CT） is generally less applied due to inferior soft tissue performance, radiation exposure, etc. This paper reviews the various imaging modalities, analyzes their advantages and disadvantages in order to assist clinicians in selecting the most appropriate examination individually.
