DDW 2016:EMR后粘膜缺损切缘热消融可显著减少腺瘤复发

2016-06-14 佚名 中国医学论坛报

本届美国消化疾病周上,一项即将公布的研究表明,内镜下粘膜切除术(EMR)后粘膜缺损切缘行热消融可显著降低首次结肠镜监测(SC1)时腺瘤复发率,常规应用此种简单安全的技术有可能增强EMR有效性并减少监测需求。  此项前瞻性多中心研究对EMR缺损切缘行辅助热消融能否降低腺瘤复发率进行了评估。主要终点为SC1时内镜和组织学复发。将标准注射和切除EMR技术应用于所有病变。排除标准包括既往尝试治疗病变、圈套

本届美国消化疾病周上,一项即将公布的研究表明,内镜下粘膜切除术(EMR)后粘膜缺损切缘行热消融可显著降低首次结肠镜监测(SC1)时腺瘤复发率,常规应用此种简单安全的技术有可能增强EMR有效性并减少监测需求。
  

此项前瞻性多中心研究对EMR缺损切缘行辅助热消融能否降低腺瘤复发率进行了评估。主要终点为SC1时内镜和组织学复发。将标准注射和切除EMR技术应用于所有病变。排除标准包括既往尝试治疗病变、圈套切除不完全和回盲瓣受累。EMR成功完整切除巨大无蒂和侧向发育结肠病变(LSL)并详细检查缺损以确保无残留腺瘤之后,以1:1比例将粘膜缺损随机给予缺损边缘热消融或不行附加治疗。在5至6个月时实施SC1,并实施标准化影像记录和瘢痕活检。
  
结果显示,共有768个≥20 mm病变接受EMR治疗,其中359个接受随机化,热消融和对照组分别为178和181个。两组的患者、操作和病变特征均相似。267例(74.3%)患者完成了SC1。SC1时,热消融组的内镜和组织学复发率均显著低于对照组(5.8%对20.2%,P<0.001,相对危险度[RR] 0.29;5.8%对20.6%,P=0.002,RR 0.28)。与组织学结果比较时,EMR后瘢痕内镜评估准确确定复发的敏感性、特异性和阴性预测值分别为100%、98%和100%。热消融和对照组在延迟出血和延迟穿孔发生率方面均无显著差异。
