RESUMO
Objective To assess whether a follow-up endoscopy after endoscopic submucosal dissec-tion(ESD)for gastric lesions is effective for prevention of delayed bleeding. Methods Papers published in Medline,Embase,Cochrane library,Elsevier,Wanfang,VIP and CNKI were searched for the studies eval-uating the efficacy of follow-up endoscopy for reducing delayed postoperative bleeding after ESD for gastric le-sions. Statistic analyses were performed using RevMan 5. 1 software. Results A total of 10 studies including 4 randomized control trials and 6 cohort studies were enrolled. Analysis of these studies showed that the inci-dence of delayed bleeding was not significantly different between the patients receiving a follow-up endoscopy and those not(OR= 1. 38,95% CI:0. 89-2. 13,P= 0. 15). Also,there was no difference in the incidence of delayed bleeding between the prophylactic hemostasis and nonprophylactic hemostasis groups( OR = 1. 45, 95% CI:0. 65-3. 22,P= 0. 36). Conclusion A follow-up endoscopy after gastric ESD may contribute little to the prevention of delayed bleeding,but may be useful for the high-risk patients,which can control the bleeding rate at a low level.
