RESUMO
The aim of this review was to systematically compare the outcomes of enhanced recovery after surgery (ERAS) with standard care (SC) after radical cystectomy. We performed a systematic search of PubMed, Ovid, Web of Science, and the Cochrane Library to identify studies published until September 2017 which involved a comparison of ERAS and SC. A meta-analysis was performed to assess the outcomes of ERAS versus SC. Sixteen studies including 8 prospective and 8 retrospective trials met the eligibility criteria. A total of 2100 participants were assigned to ERAS (1258 cases) or SC (842 cases). The time to first flatus passage {WMD=-0.95 days, 95% CI (-1.50,-0.41), P=0.0006}, time until return to a regular diet {WMD=-2.15 days, 95% CI (-2.86,-1.45), P<0.00001} and the length of hospital stay {WMD=-3.75 days, 95% CI (-5.13,-2.36), P<0.00001} were significantly shorter, and the incidence of postoperative complications {OR=0.60, 95% CI (0.44, 0.83), P=0.002}, especially postoperative paralytic ileus {OR=0.43, 95% CI (0.30, 0.62), P<0.00001} and cardiovascular complications {OR=0.28, 95% CI (0.09, 0.90), P=0.03} was significantly lower in the ERAS group than those in the SC group. This meta-analysis demonstrated that ERAS was associated with a shorter time to first flatus passage, return of bowel function, and the length of hospital stay than SC in patients undergoing radical cystectomy, as well as a lower rate of postoperative complications, especially paralytic ileus and cardiovascular complications.
