Laparoscopic versus robotic-assisted, left-sided colectomies: intra- and postoperative outcomes of 683 patients
2022
Overview
BackgroundRobotic-assisted colorectal surgery has gained more and more popularity over the last years. It seems to be advantageous to laparoscopic surgery in selected situations, especially in confined regions like a narrow male pelvis in rectal surgery. Whether robotic-assisted, left-sided colectomies can serve as safe training operations for less frequent, low anterior resections for rectal cancer is still under debate. Therefore, the aim of this study was to evaluate intra- and postoperative results of robotic-assisted laparoscopy (RAL) compared to laparoscopic (LSC) surgery in left-sided colectomies.MethodsBetween June 2015 and December 2019, 683 patients undergoing minimally invasive left-sided colectomies in two Swiss, high-volume colorectal centers were included. Intra- and postoperative outcome parameters were collected and analyzed. ResultsA total of 179 patients undergoing RAL and 504 patients undergoing LSC were analyzed. Baseline characteristics showed similar results. Intraoperative complications occurred in 0.6% of RAL and 2.0% of LSC patients (p = 0.193). Differences in postoperative complications graded Dindo ≥ 3 were not statistically significant (RAL 3.9% vs. LSC 6.3%, p = 0.227). Occurrence of anastomotic leakages showed no statistically significant difference [RAL n = 2 (1.1%), LSC n = 8 (1.6%), p = 0.653]. Length of hospital stay was similar in both groups. Conversions to open surgery were significantly higher in the LSC group (6.2% vs.1.7%, p = 0.018), while stoma formation was similar in both groups [RAL n = 1 (0.6%), LSC n = 5 (1.0%), p = 0.594]. Operative time was longer in the RAL group (300 vs. 210.0 min, p < 0.001).ConclusionRobotic-assisted, left-sided colectomies are safe and feasible compared to laparoscopic resections. Intra- and postoperative complications are similar in both groups. Most notably, the rate of anastomotic leakages is similar. Compared to laparoscopic resections, the analyzed robotic-assisted resections have longer operative times but less conversion rates. Further prospective studies are needed to confirm the safety of robotic-assisted, left-sided colectomies as training procedures for low anterior resections.
