摘要
<正>炎症性肠病(inflammatory bowel disease,IBD)分为溃疡性结肠炎(ulcerative colitis,UC)和 Crohn’s病(Crohn’s dis-ease,CD),是小肠和大肠由炎症和溃疡引起的一组慢性疾病,并可在一生中反复发作[1-3]。UC溃疡可影响结肠和直肠内壁的内层内部,以慢性复发性的肠部炎症为特征,炎症是连续的并且主要局限于直肠和结肠的粘膜层,没有瘘管和肉芽肿。CD则可延伸到肠内壁的深层[4],可以影响胃肠道的任一部分,但是经常局限于回肠末端和结肠,肠部炎症是透壁和不连续的,它可能包括肉芽肿或联合肠瘘和肛瘘[5]。CD和UC在美国的流行率为2‰~3‰[6]。UC有近10%的局限在直肠和结肠的患者不能确定是CD还是UC,只能定义为“不确定性大肠炎”[7,8]。UC和CD都有皮肤、眼睛或关节等部位的肠外炎症,以CD多见。
