Original Article


Robotic-assisted surgery is increasingly being utilized for colorectal surgery. Data are scarce and contradictory when outcomes are compared between robotic and laparoscopic surgery. All patients undergoing minimally invasive colorectal surgery were compared from 2011 to 2016. Outcomes between the two groups were statistically analyzed. p < 0.05 was considered statistically significant. 185 patients underwent laparoscopic resection and 70 underwent robotic resection. Demographics, ASA score, and BMI were similar between the two groups (p > 0.05). There was no statistical difference in median length of stay between laparoscopic and robotic colon (both 4 days; p = 0.5) and rectal (6 vs 4.5 days; p = 0.2) resections. Median operative times were also similar between the two approaches for colon (150.5 vs 169.5 min, p = 0.2) and rectal (197.0 vs 231.5 min, p = 0.9) resections. There was also no difference in operative time between the two approaches for right (median = 137 vs 130.5 min; p = 0.9) and left (median = 162.0 vs 170.5 min; p = 0.6) colectomies. Robotic surgery results in similar operative times and length of stay as laparoscopic surgery for patients undergoing colon and rectal resections.
