EMR is established as the primary approach for large and complex dysplastic lesions. However, submucosal fibrosis caused by previous attempts at removal, biopsy sampling, inflammation, or tattoo placement can cause a benign “negative lift sign” and create difficulty for EMR. Here, we present the use of distal cap–assisted EMR (EMR-DC) specifically for the use of resecting dysplastic colonic lesions when submucosal fibrosis is present in patients with inflammatory bowel disease (IBD).

远端帽辅助 EMR 允许在炎症性肠病的情况下安全有效地切除依从性发育不良病变：一项多中心回顾性研究（附视频）


EMR 被确定为大而复杂的异型增生病变的主要方法。然而，由先前尝试切除、活检取样、炎症或纹身放置引起的粘膜下纤维化可导致良性的“负提升征”，并给 EMR 带来困难。在这里，我们介绍了远端帽辅助 EMR （EMR-DC） 的使用，专门用于在炎症性肠病 （IBD） 患者存在粘膜下纤维化时切除发育不良结肠病变。
