较大直肠腺瘤中经肛门内镜显微手术与内镜下黏膜切除术的随机对照试验(TREND研究)

Randomised controlled trial of transanal endoscopic microsurgery versus endoscopic mueosal resection for large rectal adenomas (TREND Study)

摘要 目的 非随机研究表明内镜下黏膜切除术(endoscopic mucosal resection,EMR)在切除直肠较大腺瘤时与经肛门内镜显微手术(transanal endoscopic microsurgery,TEM)同样有效,但EMR可能更具成本效益且相对安全。本试验旨在对比摘除较大直肠腺瘤时EMR与TEM的临床结局与成本效益。
