AIM: to evaluate transanal total mesorectal excision (TA TME) learning curve.PATIENTS AND METHODS: sixty-five patients with mid- and low сT2-T4aN0-2bM0-1 rectal cancer were included.RESULTS: mean total operating time was 272.4±50.8 (190-400) minutes and after 17 th case it has decreased. Mean operating time of transanal phase was 84.9±43.2 (40-200) minutes and after 20 th case it has also decreased. The rate of intraoperative complications was 8 (12.3%), postoperative morbidity – 25 (38.4%) cases. These indicators have decreased after 18 th and 20 th cases respectively. Conversion rate was 2 (3.0%) cases and have decreased after 6 th case. Grade 1 specimens were revealed in 9 (13.8%) cases and have decreased after 16 th case.CONCLUSION: TA TME learning curve in high-volume colorectal unit is 16-20 cases.
