Purpose
A robotic system was mainly designed to allow precise dissection in deep and narrow spaces. We report the clinical and oncologic outcomes of totally robotic total mesorectal excision for rectal cancer.
Methods
Between July 2009 and January 2012, 60 consecutive patients undergoing robotic surgery for rectal cancer at the Eulji University Hospital were included.
Results
The mean total operation time, docking time, and surgeon console time were 466.8 ± 115.6, 7.5 ± 6.7, and 261 ± 87.5 min, respectively. Oral intake of diet was started at 3.3 ± 0.9 days and the mean hospital stay was 8.6 ± 2.4 days. All 60 procedures were technically successful without the need for conversion to open or laparoscopic surgery. Complications included anastomotic leakage, anastomotic stricture, postoperative bleeding, ileus, and perineal wound infection in 3 (5 %), 1 (1.7 %), 2 (3.3 %), 2 (3.3 %), and 1 (1.7 %) patient, respectively. The mean distal resection margin and total number of lymph nodes harvested was 3.1 ± 1.7 cm and 20.1 ± 11.5, respectively. During the mean follow-up period of 48.5 months (range, 7–75), the 4-year overall and disease-free survival rates were 87.7 and 72.8 %, respectively.
Conclusions
A totally robotic approach for rectal cancer operations was a time-consuming procedure, although we already had a lot experience in laparoscopic colorectal surgery. However, the dexterity of the robotic surgery could enable the surgeon to expand the choice of surgical methods according to the condition of the rectal cancer without the need for conversion.
