Strategies to Reduce Ileus After Colorectal Surgery: Key Findings on Effective Interventions

Researchers conducted an umbrella review of 26 systematic reviews to determine strategies for reducing postoperative ileus after colorectal surgery. The most effective interventions included early oral feeding, chewing gum, and alvimopan. Early oral feeding accelerated bowel function return, while gum chewing reduced postoperative ileus by 45% and shortened time to first flatus and defecation. Coffee intake had inconsistent results. Medications such as alvimopan, intravenous lidocaine, dexamethasone, probiotics, and oral antibiotics helped hasten bowel function return. Acupuncture positively impacted recovery of bowel function.
