Abstract
With global expansion of robotic surgery, there is increasing interest in its application in colonic surgery. This study aimed to report the feasibility of robotic assisted colonic resection as a post hoc analysis of a randomised controlled trial (RCT) by comparing outcomes following laparoscopic and robotic colectomy. The PAROS trial was a phase III RCT that compared outcomes in low pressure (LP, 7 mmHg) and standard pressure (SP, 12 mmHg) pneumoperitoneum in elective colectomy. A post hoc analysis was performed to compare clinical and operative outcomes in laparoscopic and robotic colonic resection in a high volume colorectal surgery practice. A health economic comparison was also performed. Data were analysed using IBM SPSS StatisticsTM, version 20. 127 patients were compared [34% (n = 43) robotic, 66% (n = 84) laparoscopic]. LP pneumoperitoneum was practiced in 47% (n = 20) robotic and 50% (n = 42) laparoscopic cases. Cancer procedures were more commonly performed in the robotic group (p = 0.009). Clinical outcomes were comparable including post-operative surgical complications (p = 0.493). Operative times were longer (p = 0.005) but length of hospital stay (LOS) was one day shorter in the robotic group (p = 0.05). Conversion to SP pneumoperitoneum was required in 9.5% (n = 8) of the LP laparoscopic group compared to 2.3% (n = 1) of the LP robotic group. Surgeons reported good operative visibility in all robotic cases and 94% (n = 80) laparoscopic cases. Considering, capital investment and maintenance, instrumentation and LOS, robotic cases were €651 more expensive per case. Robotic-assisted surgery is feasible in colonic resection and may facilitate shorter LOS and the possibility to complete MIS using low pressure pneumoperitoneum.
