RESUMO
Objective:The safety and effectiveness of the enhanced recovery after surgery (ERAS) in the treatment of distal pancreatectomy (DP) were evaluated by meta-analysis.Methods:Pancreatic body and tail resection, distal pancreatic resection, ERAS, rapid recovery after surgery, pancreatectomy, DP and ERAS were used as key words, and the network database such as Chinese journal full-text database, Wanfang data knowledge service platform, Weipu database, Chinese biomedical literature database, Pubmed, Embase, Cochrane library, Web of science, Sciencedirect and so on were searched. The retrospective literatures published from the database establishment to May 2022 were retrieved from the network database, and the papers were screened and the quality was evaluated according to the pre-set inclusion and exclusion criteria; and important data were extracted. The software Review Manager 5.4 was used for meta-analysis.Results:9 papers were finally included, and a total of 650 patients with DP were enrolled (311 in the ERAS group and 339 in the NO-ERAS group). Meta-anaysis showed that compared with NO-ERAS group, ERAS group could reduce intraoperative bleeding ( MD=-73.88, 95% CI -121.21--26.55, P=0.002), decrease the incidence of postoperative complications ( OR=0.48, 95% CI 0.32-0.72, P<0.001) and pulmonary complications ( OR=0.47, 95% CI 0.24-0.93, P=0.030), shorten the postoperative exhaust time (MD=-8.76, 95% CI -11.23--6.29, P<0.001), postoperative length of hospital stay ( MD=-2.65, 95% CI -3.06--2.07, P<0.001) and abdominal drainage tube removal time ( MD=-1.45, 95% CI -1.81--1.09, P<0.001). However, ERAS could not shorten the operative time ( MD=6.25, 95% CI -4.56-17.07, P=0.260), reduce the incidence of postoperative pancreatic fistula ( OR=0.92, 95% CI 0.53--1.60, P=0.780) and the re-admission rate within 30 days after surgery ( OR=1.00, 95% CI 0.47-2.11, P=0.990). Conclusions:ERAS is safe and effective for patients undergoing DP, because it can reduce intraoperative bleeding and postoperative complications, shorten postoperative hospital stay and postoperative abdominal drainage tube removal time.
