    Abstract:
    Robotic surgery became more popularly in the colorectal surgical field. The aim of the study was to evaluate of the oncological outcomes which patients who underwent the robotic total mesorectal excision for rectal cancer. A series of 140 consecutive patients who underwent robotic rectal surgery between January 2012 and June 2019 was analyzed retrospectively in terms of demographics, pathological data, and surgical and oncological outcomes. There were 104 (74.28%) male and 36 (25.71%) female patients. The tumor was located in the lower rectum in 84 (60%) cases, in the mid rectum in 38 (27.14%) cases, and in the upper rectum in 18 (12.85%) cases. Ninety-eight (70%) of the patients has received neoadjuvant chemoradiotherapy. All the patients underwent robotic sphincter-preserving surgery, 101 (72.14%) patients low-anterior resection, and 39 (27.85%) patients underwent intersphincteric resection with colo-anal anastomosis. There were no conversions. The circumferential resection margin was positive in five (3.57%) patients. The median distal resection margin of the operative specimen was 3.2 (0.2-7) cm. The median number of retrieved lymph nodes was 22 (16-42). TME quality in the in our study was rated as complete in 88.57% (n124) of patients, nearly complete in 7.14% (n10) of patients; and 4.28% (n6) of incomplete. The median hospital stay was 3.5 (3-12) days. In-hospital and 1-month mortality was zero. The median length of follow-up was 40 (2-80) months. The 5-year overall survival rate was 92.78%. The 5-year disease-free survival rate was 90%. Locally recurrence and distance recurrence rate was 3.57% (n5/140) and 2.85% (n4/140), respectively. Robotic rectal cancer surgery has a good oncological outcomes and feasible tool in the field of the rectal surgery, but required a steep learning curve.
