Abstract
Aim: To evaluate the feasibility, safety, and short-term oncological outcomes of robotic-assisted total mesorectal
excision (TME) in patients with low-lying rectal cancer (≤ 5 cm from anal verge).

Methods: We enrolled 60 patients with stages I-III low-lying rectal cancer who underwent robotic-assisted TME at a
single institution between July 2013 and April 2017.

Results: Of the 60 patients enrolled, 49 (81.6%) underwent preoperative concurrent chemoradiotherapy. Furthermore,
among these 49 patients, 18 (36.7%) achieved a pathologic complete response. R0 resection was performed in 57
