Abstract:To evaluate the clinical value of endoscopic retrograde appendicitis therapy in the treatment of uncomplicated acute appendicitis. Methods The literature on endoscopic retrograde appendicitis therapy in treating patients with uncomplicated acute appendicitis was retrieved combined with manual retrieval from PUBMED, China national knowledge infrastructure (CNKI), Web of Knowledge, the Cochrane controlled trials register library repository, Wanfang Database published between inception and June 2018 in China. RevMan 5.0 software from Cochrane cooperation network was used for data analysis. Pooled odds ratio (OR) or Mean difference (MD) and 95% confidence intervals (95%CI) were calculated and the heterogeneity was also assessed. Results According to the selection criteria, 8 clinical trials with five hundred and thirty seven patients were selected finally. The combined results of meta-analysis showed that compared with traditional method, endoscopic retrograde appendicitis therapy had shorter hospital stay (MD = -2.11, 95%CI: -3.10 ~ -1.11, P < 0.05), low complication rate (OR = 0.27, 95%CI: 0.13 ~ 0.56, P < 0.05), shorter operative time (MD = -23.46, 95%CI: -29.97 ~ -16.96, P < 0.05). Conclusion Our study indicates that endoscopic retrograde appendicitis therapy in treating patients with uncomplicated acute appendicitis is safety and efficacy. It has the advantages of shorter hospital stay, low complication rate, shorter operative time, and which is worthy of clinical promotion and application.
