No differences in short-term morbidity and mortality after robot-assisted laparoscopic versus laparoscopic resection for colonic cancer: A case-control study of 263 patients

Background: Robot-assisted laparoscopy has been reported to be a safe and feasible alternative to traditional laparoscopy. The aim of this study was to compare short-term results in patients with colonic cancer who underwent robot-assisted laparoscopic colonic resection (RC) or laparoscopic colonic resection (LC). Methods: The study was a retrospective case control study of all patients with colonic cancer who underwent RC from March 2010 to March 2012 or LC from January 2009 to December 2011 at a tertiary-care university hospital. Data were retrieved from the national chart database and patient journals. Biochemical markers [C-reactive protein (CRP), hemoglobin, white blood cell count, and thrombocyte count] were recorded before surgery and for the first 3 days after surgery. Results: A total of 101 patients underwent RC and 162 patients underwent LC. There were no significant differences in the rate of conversion to open surgery, number of permanent enterostomies, number of intraoperative complications, level of postoperative cellular stress response, number of postoperative complications, length of postoperative hospital stay, or 30-day mortality between the two groups. There was a significantly longer setup time for RC (77.1 vs. 69.7 min, P = 0.000), but surgical time was significantly shorter for RC (165.8 vs. 183.4 min, P = 0.006) and there was no difference in the overall procedure time (254.0 vs. 243.6 min, P = 0.086). Conclusion: We found RC to be a safe and feasible alternative to LC for colonic cancer. We found that for RC surgical time was shorter and overall procedure time was comparable to that for LC; however, these results should be confirmed in future randomized clinical trials.
