This systematic review and meta-analysis compared robotic-assisted with standard laparoscopic surgery for colorectal cancer in obese patients. Six studies involving 4215 patients were included. Robotic-assisted surgery was associated with a statistically significant but modest reduction in hospital stay (p = 0.02). Drainage tube removal time, first ventilation time, complication rates, readmissions and reoperations did not differ significantly between approaches. The authors concluded that the shorter stay was not accompanied by evidence of compromised safety, while advising caution and calling for randomised trials to confirm the findings.
Key findings
- Robotic-assisted surgery was associated with a modestly shorter hospital stay than laparoscopic surgery (p = 0.02).
- Complication rates did not differ significantly (OR = 0.92, 95% CI: 0.74 to 1.13, p = 0.41).
- Readmission rates (OR = 0.81, 95% CI: 0.31 to 2.13, p = 0.67) and reoperation rates (OR = 1.20, 95% CI: 0.77 to 1.86, p = 0.41) showed no significant differences.
Why it matters
For obese patients undergoing colorectal cancer surgery, the pooled evidence suggests robotic assistance may be associated with a modestly shorter hospital stay, without significant differences in the reported safety outcomes. The findings help frame the comparative evidence but do not establish that robotic surgery is superior, particularly because the review calls for confirmation in randomised trials.
What to keep in mind
The meta-analysis included six studies, and the authors advise caution; randomised controlled trials are needed to confirm the findings.
