Objective  To summarize the research progress of transanal total mesorectal excision (TaTME) for rectal cancer. Methods  The literatures about current status, limitations, and prospects of TaTME in China and abroad were collected to make an reviewe. Results  TaTME is conformed to the principle of total mesorectal excision (TME), by using the ‘bottom-up’ approach and assisting in the laparoscopic technique platform, to ensure an adequate oncological distal margin, and it could improve the quality of the mesorectum specimens, reduce the circumferential margin involvement rate, afford more precise autonomic nerve preservation rate, and increase sphincter preservation rate. But it is also facing new complications, oncological and functional outcomes problems. Conclusions  Although the experience with TaTME remains limited, the safety, feasibility, and short-term outcomes are acceptable. Nevertheless, there is a need for multicenter, large sample size, and long-term follow-up clinical studies focusing on the long-term outcomes to further improve the oncological safety of TaTME, before widespread application can be recommended.
