Improved perioperative and short-term outcomes of robotic versus conventional laparoscopic colorectal operations.

Abstract Background Robotic assistance may offer unique advantages over conventional laparoscopy in colorectal operations. Methods This prospective observational study compared operative measures and postoperative outcomes between laparoscopic and robotic abdominal and pelvic resections for benign and malignant disease. Results From 2005 through 2012, 200 (58%) laparoscopic and 144 (42%) robotic operations were performed by a single surgeon. After adjustment for differences in demographics and disease processes using propensity score matching, all laparoscopic operations had a significantly shorter operative time ( P P = .01); and laparoscopic right colectomies had a higher risk for overall complications ( P = .03) and postoperative ileus ( P = .04). There were no significant differences in the outcomes of pelvic operations ( P = .15). Conclusions Compared with conventional laparoscopy, some types of robotic-assisted colorectal operations may offer advantages regarding postoperative length of stay and perioperative complications.
