Abstract
Robotic-assisted laparoscopic surgery attempts to facilitate rectal surgery in the narrow space of the pelvis. The aim of this study is to compare the outcomes of robotic versus laparoscopic surgery for rectal cancer. Monocentric retrospective study including 300 patients who underwent robotic (n = 178) or laparoscopic (n = 122) resection between Jan 2009 and Dec 2017 for high, mid and low rectal cancer. The robotic and laparoscopic groups were comparable with regard to pretreatment characteristics, except for sex and ASA status. There were no statistical differences between groups in the conversion rate to open surgery. Surgical morbidity and oncological quality did not differ in either group, except for the anastomosis leakage rate and the affected distal resection margin. There were no differences in overall survival rate between the laparoscopic and robotic group. Robotic surgery could provide some advantages over conventional laparoscopic surgery, such as three-dimensional views, articulated instruments, lower fatigue, lower conversion rate to open surgery, shorter hospital stays and lower urinary and sexual dysfunctions. On the other hand, robotic surgery usually implies longer operation times and higher costs. As shown in the ROLARR trial, no statistical differences in conversion rate were found between the groups in our study. When performed by experienced surgeons, robotic surgery for rectal cancer could be a safe and feasible option with no significant differences in terms of oncological outcomes in comparison to laparoscopic surgery.
