Abstract: ransanal total mesorectal excision is a hot topic in the field of colorectal surgery. After nearly ten years of development, it has entered a period of rapid deve-lopment. Due to the difference between the traditional surgical approach and the previous one, more sufficient preconditions are needed to carry out TaTME cautiously. Therefore, systematic and stan-dardized training is indispensable. Compared with the mature foreign cadaver training courses, the domestic cadaver training is limited, while the traditional laparoscopic animal training model has limited effects on the training of transanal endoscopic surgery. Therefore, how to use the existing domestic conditions to build a training system suitable for Chinese national conditions, so as to standardize the implementation of transanal total mesorectal excision, improve the safety of new technologies, has become an urgent problem to be solved. This article has reviewed deve-lopment-history of TaTME training and investigated establishment of TaTME training system, intending to provide refe-rences for standardization of TaTME.
