Nutritional interventions to improve recovery from postoperative ileus

Area of Science:

• Gastroenterology
• Surgical Nutrition
• Clinical Outcomes

Background:

• Postoperative ileus (POI) significantly impacts patient morbidity after surgery.
• Enhanced Recovery After Surgery (ERAS) programs have improved postoperative outcomes.
• Enteral nutrition is a key component of ERAS, with potential therapeutic effects on POI.

Purpose of the Study:

• To review the role of enteral nutrition in managing postoperative ileus (POI).
• To examine the impact of enteral nutrition timing and composition on POI.
• To assess the effectiveness of ERAS programs incorporating enteral nutrition for POI reduction.

Main Methods:

• Review of existing literature on enteral nutrition and POI.
• Analysis of experimental studies on enteral feed composition and timing.
• Evaluation of clinical studies in colorectal and rectal cancer surgery patients.

Main Results:

• Early enteral nutrition can reduce complications, including POI, but study results are heterogeneous.
• Experimental data suggest lipid-enriched nutrition before, during, and after surgery is most effective for POI.
• Clinical studies show mixed results: direct tube feeding reduced POI in rectal cancer surgery, but perioperative lipid-enriched nutrition did not in colorectal surgery within ERAS.

Conclusions:

• Postoperative ileus (POI) remains a significant factor in colorectal surgery recovery.
• Enteral nutrition is a promising therapeutic strategy for POI.
• While timing and composition are crucial, perioperative lipid-enriched enteral nutrition did not reduce POI in colorectal surgery patients within an ERAS protocol.
