Input: We included seven RCTs with a total of 1202 participants. Overall, we judged the risk of bias as low in four studies and high in three studies. We are uncertain whether Daikenchuto reduced time to first flatus (mean difference (MD) -11.32 hours, 95% confidence interval (CI) -17.45 to -5.19; two RCTs, 83 participants; very low-quality evidence), or time to first bowel movement (MD -9.44 hours, 95% CI -22.22 to 3.35; four RCTs, 500 participants; very low-quality evidence) following surgery. There was little or no difference in time to resumption of regular solid food following surgery (MD 3.64 hours, 95% CI -24.45 to 31.74; two RCTs, 258 participants; low-quality evidence). There were no adverse events in either arm of the five RCTs that reported on drug-related adverse events (risk difference (RD) 0.00, 95% CI -0.02 to 0.02, 568 participants, low-quality evidence). We are uncertain of the effect of Daikenchuto on patient satisfaction (MD 0.09, 95% CI -0.19 to 0.37; one RCT, 81 participants; very low-quality of evidence). There was little or no difference in the incidence of any re-interventions for postoperative ileus before leaving hospital (risk ratio (RR) 0.99, 95% CI 0.06 to 15.62; one RCT, 207 participants; moderate-quality evidence), or length of hospital stay (MD -0.49 days, 95% CI -1.21 to 0.22; three RCTs, 292 participants; low-quality evidence). Evidence from current literature was unclear whether Daikenchuto reduced postoperative ileus in patients undergoing elective abdominal surgery, due to the small number of participants in the meta-analyses. Very low-quality evidence means we are uncertain whether Daikenchuto improved postoperative flatus or bowel movement. Further well-designed and adequately powered studies are needed to assess the efficacy of Daikenchuto.
Output:

We included seven studies (1202 participants), in which the participants were allocated at random (by chance alone) to receive one of several clinical interventions, where Daikenchuto was compared with any other medicine, placebo, or no treatment. The searches were performed 3 July 2017. We evaluated: time from completion of abdominal surgery to first flatus, time to first bowel movement, time to resumption of regular solid food intake, adverse events related to Daikenchuto, patient satisfaction, re-interventions for postoperative ileus before leaving hospital, and length of hospital stay. Overall, there were a small number of participants included in each analysis. We could not fully investigate time from surgery to first flatus, to first bowel movement, or to resumption of regular solid food intake, any medicine-related adverse events, patient satisfaction, any re-interventions for postoperative ileus before leaving hospital, or length of hospital stay. We considered the quality of evidence for all presented outcomes as moderate to very low. Based upon our findings, it was uncertain whether Daikenchuto accelerated post-surgical bowel motility in persons undergoing abdominal surgery, and thus, unclear whether Daikenchuto reduced postoperative ileus.
