Research background

Gastrointestinal tract surgery is a complex process, with a wide range of operations and large trauma. It is easy to have various infectious complications in postoperative recovery, which affects the efficacy of surgical treatment.

Research motivation

Early postoperative nutritional support can provide necessary nutrition, restore intestinal barrier, and reduce complications.

Research objectives

This study aimed to assess whether early postoperative nutritional support can improve the nutritional status of patients based on literature search and meta-analysis.

Research methods

This study used literature retrieval and meta-analysis to conduct quantitative analysis.

Research results

It was found that early enteral nutrition (EN) support could shorten the defecation time after gastrointestinal surgery, the overall hospital stay, reduce the incidence of complications, and speed up the rehabilitation process.

Research conclusions

Early enteral nutritional support can slightly shorten the defecation time and overall hospital stay, reduce complication incidence, and accelerate the rehabilitation process of patients undergoing gastrointestinal surgery.

Research perspectives

More clinical multicenter, large-sample, high-quality studies are needed to further evaluate the effect of early EN support on patient's nutritional status.
