胶囊内镜对小肠克罗恩病诊断及疾病活动评估的价值

Value of capsule endoscopy for diagnosis and assessment of disease activity in small bowel Crohn′s disease

克罗恩病(CD)是一种累及全消化道的慢性透壁性炎性疾病,以回结肠受累常见。目前胶囊内镜(CE)因其安全性和便捷性,在小肠CD的诊断与评估中得到越来越多的应用,尤其是对早发型小肠CD及不典型小肠CD的诊断具有独特价值。CE对于完善和修正CD的病变范围和程度、准确评估疾病活动度也具有重要意义,但CE也有其局限性。本文就CE在早期小肠CD的诊断、疾病累及范围及活动度评估,如何正确看待其滞留的风险进行综述,为临床实践提供参考。

Crohn′s disease(CD)is a chronic transmural inflammation disease which may affect the whole gastrointestinal tract.It is known that ileal and colonic involvement of CD is common.Capsule endoscopy(CE)is widely used for CD because of its noninvasiveness and convenience,especially for diagnosis of early-onset and atypical small bowel CD.CE also plays an important role in improving and modifying disease extent and assessment of disease activity.However,CE has its limitations.We mainly summarize the efficacy of CE for early-onset diagnosis and evaluation of extent and activity in small bowel CD.The retention risks are also reviewed to give some references for clinical practice.
