Purpose
Scarce research has reported the comparison between robotic and laparoscopic surgery in mid–low rectal cancer. Therefore, this meta-analysis is aimed to compare the safety and efficacy of the two surgical approaches.
Methods
A comprehensive search of the databases (PubMed, EMBASE, Cochrane, and Web of Science) was performed for studies comparing robotic and laparoscopic surgery. The outcomes of interest acquired from eight articles included three aspects: intraoperative conditions, postoperative status of patients, and complications. All data (robotic = 1350 patients, laparoscopic = 1330 patients) enrolled were analyzed using Rev Man 5.4.
Results
Compared to the laparoscopic group, the robotic group indicated a noticeable superiority in estimated blood loss (P < 0.0001), number of lymph nodes dissected (P = 0.004), time to first flatus (P = 0.001), time to first fluid diet (P = 0.001), hospital stay (P < 0.0001), conversion (P = 0.009), and urinary retention (P = 0.0006), but devoted much more operation time (P = 0.0004).
Conclusion
Robotic surgery was associated with superiority over laparoscopic surgery in increasing surgical safety, accelerating postoperative recovery, and reducing complications, which suggested that robotic surgery could be a safe and effective method for treating mid–low rectal cancer.
