Robotic versus laparoscopic surgery for colorectal cancer in older patients: a systematic review and meta-analysis

摘要

OBJECTIVE: Robotic surgery is being increasingly used for colorectal cancer surgery. However, its utility versus laparoscopic surgery in older patients is unclear. We systematically examined evidence to assess the differences in short-term outcomes of robotic versus laparoscopic surgery for colorectal cancer in older patients. MATERIAL AND METHODS: Comparative studies published on PubMed, Web of Science, Embase, and CENTRAL databases were searched up to August 30th, 2023. RESULTS: Seven studies totaling 14,043 patients were included. Meta-analysis showed no difference in the operation time between the robotic and laparoscopic groups. Meta-analysis of ClavienDindo complications showed no difference between the robotic and laparoscopic groups for grades I and II or grades III and IV complications. Similarly, conversion to open surgery, reoperation rates and length of hospital stay were not significantly different between the two groups. Readmission rates and mortality rates were significantly lower with robotic surgery. CONCLUSION: This first meta-analysis comparing outcomes of robotic and laparoscopic surgery in older colorectal cancer patients shows that both approaches result in no difference in operating time, complication rates, conversion to open surgery, reoperation rates, and LOS. Scarce data shows that mortality and readmission rates may be lower with robotic surgery.
