Effects of enhanced recovery after surgery on robotic radical prostatectomy: a systematic review and meta-analysis

Enhanced recovery after surgery (ERAS) has been shown to be an effective, reliable and practical clinical nursing method to support operations on a range of physiological systems, but its effects on robotic radical prostatectomy (RRP) are still unclear. This study assesses the clinical effects of ERAS in RRP.

Various databases including PubMed, EMBASE, Web of Science and China National Knowledge were searched for relevant studies, in particular full-text articles comparing ERAS groups and conventional groups for RRP. All included articles were subject to a quality assessment, and the data analysis was conducted with Review Manager (5.3). Forest plots, sensitivity analyses, and bias analyses were also prepared based on the included articles.

In total, 8 studies were identified that met the inclusion criteria. The results showed that ERAS groups exhibited significantly reduced time of flatus [mean difference (MD) =-0.58; 95% confidence interval (CI): -0.88, -0.29; P=0.0001], time of catheter removal (MD =-1.65; 95% CI: -2.15, -1.16; P<0.00001), and length of stay (LOS) (MD =-1.49; 95% CI: -2.65, -0.34; P=0.01), and there was no significant difference in terms of postoperative complications between ERAS groups and conventional groups (P=0.07).

This study provides further evidence that ERAS improves postoperative recovery in patients undergoing RRP through reduced time of first flatus, time of catheter removal and LOS. Given the limited quality and quantity of the articles included in this study, further work is needed to validate these findings.
