Eight treatments effectively reduce postoperative ileus.

An umbrella review of 24 meta-analyses revealed eight treatments that significantly alleviate postoperative ileus. Chewing gum, coffee, enhanced recovery after surgery (ERAS) protocols, acupuncture, opioid receptor antagonists, da-cheng-qi-tang, early enteral nutrition, and zusanli point injection therapy improved outcomes. Additionally, opioid receptor antagonists, early enteral nutrition, ERAS, and chewing gum notably shortened postoperative hospital stays. However, the safety and effectiveness of other treatment methods require further high-quality investigation.
