Effect of early enteral immunonutrition intervention on gastrointestinal hormones , stress hormones and immune response after pancreatic cancer surgery

Pancreatic cancer is a type of malignant tumor in the digestive tract with extremely high malignant degree, and patients with pancreatic cancer who are eligible for surgical indications need to undergo radical resection in time. The radical operation for pancreatic cancer is with wide range of resection and causes great surgical trauma, which will not only affect the postoperative gastrointestinal peristalsis and the body’s nutritional status, but will also cause stress reaction activation and immune response inhibition. Perioperative related research in recent years has shown that early enteral nutrition intervention after gastrointestinal surgery can not only improve the nutritional status of the body, but can also promote gastrointestinal peristalsis function recovery and protect the intestinal mucosal barrier function[1]. Enteral immunonutrition preparation is a newly developed enteral nutrition preparation, which contains the arginine and ω-3 polyunsaturated fatty acids with immunoregulation activity and anti-oxidative stress activity[2]. In the following studies, we specifically analyzed the effect of early enteral immunonutrition intervention on gastrointestinal hormones, stress hormones and immune response after pancreatic cancer surgery.
