消化内镜手术术中出血分级法

New classifications of muscularis propria defect and mucosal injury during digestive endoscopic tunnel technique

近年来,随着消化内镜技术的发展,内镜下电凝电切术、内镜下黏膜切除术(endoscopic mucosal resection,EMR)、内镜下分片黏膜切除术(endoscopic piecemeal mucosal resection,EPMR)、内镜黏膜下剥离术(endoscopic submucosal dissection,ESD)、多环套扎切除术(multiband mucosectomy,MBM)、内镜黏膜下挖除术(endoscopic submucosal excavation,ESE)、内镜下全层切除术(endoscopic full-thickness resection,EFR)、消化内镜隧道技术(digestive endoscopic tunnel technique,DETT)[1]等内镜下手术被广泛应用。相比于外科手术,内镜手术具有安全、微创、术后恢复快等优点[2-3],评估内镜手术安全性的主要指标为观察其术中、术后并发症发生情况。
