Abstract
Objective: To evaluate the effect of chewing sugar-free gum on gastrointestinal function recovery after cesarean section. Methods: Randomized controlled trials comparing the use of chewing gum in postoperative recovery with a control group were retrieved from the databases including Pubmed, Cochrane Library, Science Direct, Web of Science, CBM, CNKI, Wanfang and VIP, et al. After screening literatures, evaluating the quality of studies, extracting data, the RevMan5.3 software was used for data analysis. Results: A total of 13 RCTs including 2233 patients were analyzed in the study. The results showed that chewing gum after cesarean delivery can effectively shorten the recovery time of bowel sounds, passage of flatus and first defecation (all P < 0.05). Conclusion: Chewing sugar-free gum after cesarean section can promote the early recovery of gastrointestinal function, but the side effects of chewing gum are still unclear, which needs more clinical, large sample and high-quality studies to further verify.
Highlights
In recent years, with the development of medical technology and related support policies, the cesarean section rate in the world has tended to rise [1]

Summary
With the development of medical technology and related support policies, the cesarean section rate in the world has tended to rise [1]. A large number of studies have shown that early feeding can effectively promote the recovery of gastrointestinal function after cesarean section, but some patients performed high intolerance [4] [5], and delayed feeding is related to increase cell break-down, delay the time of wound healing and increase the risk of infection, thereby increasing medical costs [6] [7]. More studies have shown that chewing gum after abdominal surgery, including cesarean section, can effectively promote early recovery of gastrointestinal function and reduce postoperative complications [9]-[23]. The aim of this study was to evaluate the effect of chewing gum on the early recovery of gastrointestinal function after cesarean section by the method of evidence-based medicine, and provide a basis for further clinical exploration of the early recovery of gastrointestinal function in patients after cesarean section
