IBD :结肠切除术边缘炎症对术后克罗恩病复发的预测价值:一项队列研究

尽管药物治疗取得了进步,但大多数克罗恩病(CD)的晚期患者仍需要手术切除。一部分患者在疾病过程中会发生术后复发。

        尽管药物治疗取得了进步,但大多数克罗恩病(CD)的晚期患者仍需要手术切除。一部分患者在疾病过程中会发生术后复发。抽烟,既往外科手术,手术中的穿透性疾病和肛周疾病是回盲肠切除术后临床和手术复发的危险因素。然而,最近的队列研究已将切除边缘的炎症确定为复发的新的独立危险因素。这项研究的目的是评估在回盲肠切除边缘的微小炎症(包括活动性炎症,肌间神经丛炎和肉芽肿)对CD患者的临床和手术复发的预测价值。

 

 

        研究人员回顾性收集了连续106例因克罗恩病而进行回盲肠切除术的患者的切除切缘标本,并对活动性炎症,肌间神经丛炎和肉芽肿进行评分。病理结果与复发相关的定义为使用多变量分析通过内镜检查(改良的Rutgeerts评分≥i2)需要扩大药物治疗范 围的复发性疾病活动。

 

 

        结果显示:在近端和远端切除术边缘分别发现活动性炎症的比例分别为27%和15%,肌间神经丛炎分别为37%和32%,肉芽肿分别为4%和6%。106例患者中有47例复发。仅结肠远端切除边缘的活动性炎症是复发的独立显着预测因子(远端,近端和无累及的边缘分别为88%vs 43%vs 51%;P <0.01)。

 

 

        研究最后作者说道:回盲肠切除后结肠远端切除边缘的活动性炎症可确定吻合部位和结肠术后复发的高风险患者组,因为它可识别出未确诊的L3疾病。这些患者具有不同且更具侵略性的自然病史,需要更深入的治疗。因此,应在日常实践中对远端切除切缘进行病理学评估。
