摘　　要：经肛全直肠系膜切除(taTME)手术尚处于发展阶段,在术适应证的选择、规范的手术流程建立、手术质量控制以及手术平台器械的改进等方面,均有提高的空间。taTME的关键技术包括:(1)肿瘤远端肠腔缝合关闭技术。(2)如何进入正确的层面间隙。(3)自下而上的直肠系膜分离技术。(4)吻合口安全性判断及加固缝合技术。鉴于taTME手术操作要求高,学习曲线长,故需要制定结构化培训方案,以快速度过学习曲线,逐步提高手术质量,同时开展高质量的临床研究,回答taTME实施过程中出现的相关问题,通过临床研究与临床实践的互相推动,提高中低位直肠癌的诊疗水平。Transanal total mesorectal excision(taTME)surgery is still in the developmental stage,and there is room for improvement regarding the selection of surgical indications,establishment of standardized surgical procedures,surgical quality control,and surgical platform instruments.taTME's key techniques include:(1)the technique of closing the rectal lumen with sutures distal to the tumor.(2)How to access the correct level gap.(3)Bottom-up rectal mesenteric separation technique.(4)Anastomosis safety judgment and reinforcement suture technique.Regarding the high requirements of taTME surgical operation and the long learning curve,it is necessary to develop a structured training program to quickly pass the learning curve and gradually improve the quality of taTME surgery.It is important to carry out high-quality clinical research to answer the relevant questions that arise during the implementation of taTME.The taTME technique can be gradually improved through the mutual promotion of clinical research and clinical practice.Finally,the level of treatment and care for low and middle rectal cancers can be improved.
