Background/objective: The reduced-port approach can overcome the limitations of single-incision laparoscopic surgery while maintaining its advantages. Here, we compared the effects of robotic reduced-port surgery and conventional laparoscopic approaches for left-sided colorectal cancer.
Methods: Between January 2015 and December 2016, the clinicopathological characteristics and treatment outcomes of 17 patients undergoing robotic reduced-port surgery and 49 patients undergoing laparoscopic surgery for left-sided colorectal cancer were compared.
Results: The two groups were comparable in almost all outcome measures except for the distal resection margin, which was significantly longer in the laparoscopic group (P < 0.001). The between-group differences in reoperation, incisional hernia development, and overall and progression-free survival were nonsignificant; however, the total hospital cost was significantly higher in the robotic group than in the laparoscopic group (US$13779.6 ± US$3114.8 vs. US$8556.3 ± US$2056.7, P < 0.001).
Conclusion: Robotic reduced-port surgery for left-sided colorectal cancer is safe and effective but more expensive with no additional benefit compared with the conventional laparoscopic approach. This observation warrants further evaluation.
