Background:
The aim of this meta-analysis was to evaluate whether adoption of DaVinci Xi® had any impact upon intra- and postoperative metrics in colorectal surgery.
Methods:
The Pubmed, CINAHL, Cochrane Library and MEDLINE (Ovid) databases were systematically searched. Operating time as well as docking and surgeon console times were the primary endpoints. Conversion and postoperative complication rates were the secondary endpoints.
Results:
Six studies totaling 610 patients (320 Si and 290 Xi) were included. Total operating time [MD (95% CI) = 30.553 (15.071, 46.035); p < 0.001], docking time [MD (95% CI) = 4.178 (2.120, 6.235); p < 0.001] and surgeon console time [MD (95% CI) = 17.246 (-0.479, 34.971); p = 0.056] were longer in DaVinci Si® as compared to DaVinci Xi® . No significant difference was found in conversion (p = 0.816) and postoperative complication rates (p = 0.405).
Conclusion:
This meta-analysis found that the adoption of DaVinci Xi® was associated with significantly decreased total operating time as well as docking and surgeon console times. Conversion and complication rates were similar.
