Safety and efficacy of gastrointestinal motility agents following elective colorectal surgery: a systematic review and meta-analysis of randomised controlled trials.

BACKGROUND

Postoperative ileus (POI) is a frequent complication after elective colorectal surgery, delaying gastrointestinal (GI) recovery and discharge. While pharmacologic agents such as laxatives and prokinetics are often included in enhanced recovery after surgery (ERAS) protocols, their efficacy and safety remain uncertain.

METHODS

A systematic review and meta-analysis of randomised controlled trials (RCTs) was conducted to evaluate the effect of Gastrointestinal (GI) motility agents on postoperative recovery in elective colorectal surgery. Primary outcomes included GI-2 recovery (tolerance of solid diet and stool passage), time to first defaecation, and safety endpoints. Data was pooled using random-effects models.

RESULTS

Seven RCTs involving 849 patients were included. GI motility agents significantly accelerated GI-2 recovery (mean difference -1.01 days; 95% CI -1.29 to -0.73; p < 0.001) and reduced time to first defaecation (mean difference -1.07 days; 95% CI -1.40 to -0.73; p < 0.001). No significant differences were observed in safety outcomes, including anastomotic leak (OR 0.97; 95% CI 0.53 to 1.77), nasogastric tube reinsertion (OR 0.86; 95% CI 0.49 to 1.51), or readmission rates (OR 1.03; 95% CI 0.62 to 1.72).

CONCLUSION

Motility agents enhance postoperative GI recovery without compromising safety in patients undergoing elective colorectal surgery. Given their low cost, wide availability, and favourable safety profile, gastrointestinal motility agents may be considered for integration into ERAS protocols. However, further high-quality, standardised trials are needed to confirm their benefits across diverse surgical populations.
