内镜黏膜下剥离术可治疗T1aN0期直肠神经内分泌(良性)肿瘤。Moon SH等研究者为了评估内镜黏膜下剥离术治疗T1aN0期直肠神经内分泌(良性)肿瘤的安全性和疗效,选择了2007年3月至2009年12月期间的35例连续病例的组织完整切除率、手术时间、并发症及短期肿瘤治疗效果。该研究患者平均年龄49.0岁(32～74岁),平均手术时间35.6 min(7～82 min),组织完整切除率达74.3%,未见内镜黏膜下剥离手术出血。1例发生非腹膜炎症状引起的穿孔,术后3 d出院。1例 Endoscopic submucosal dissection can treat T1aN0 rectal neuroendocrine (benign) tumors. To evaluate the safety and efficacy of endoscopic submucosal dissection in the treatment of T1aN0 rectal neuroendocrine (benign) tumors, Moon SH et al. Selected 35 consecutive cases of complete tissue resection between March 2007 and December 2009 Rate, operation time, complications and short-term effect of tumor treatment. The average age of the patients was 49.0 years old (32-74 years). The average operation time was 35.6 minutes (7-82 minutes). The complete resection rate was 74.3%. There was no endoscopic submucosal dissection bleeding. Perforation caused by non-peritonitis symptoms occurred in 1 case and was discharged after 3 days. 1 case
