Abstract: Postoperative ileus (POI), one of the most common postoperative complications, impacts digestive function through neural reflex and intestine inflammation, and severely influences the therapeutic effect as well as the long-term outcome of the patients. As a major component of comprehensive peri-operative therapies, nutrition support treatment provides necessary daily energy and nutrient support for the patients, effectively prevents POI and promotes digestive motility. Therefore, the authors further elaborate on nutrition support treatment for postoperative ileus based on the latest research worldwide.
