Effect of Preoperative Nutritional Risk Screening and Enteral Nutrition Support in Accelerated Recovery after Resection for Esophageal Cancer.

Patients with esophageal cancer are often accompanied by malnutrition, especially in patients with obvious swallowing tract. Many studies have shown that preoperative nutritional support can reduce postoperative complications, but there are few studies comparing preoperative enteral nutrition with intravenous nutrition. The aim of the study was to compare the effects of the two nutritional support path in esophageal cancer patients undergoing surgery. We used the nutritional risk screening 2002 (NRS2002) for preoperative nutritional risk screening in patients with esophageal cancer treated at our department between April 2016 and March 2019. A total of 56 patients with an NRS2002 score ≥ 3 and with apparent difficulty swallowing received preoperative parenteral nutrition (PN; n = 29) or enteral nutrition (EN; n = 27). Both groups received 7 day of nutritional support before surgery. Nutritional indicators were measured on preoperative day 7, preoperative day 1, and postoperative day 7. The baseline characteristics, perioperative condition, nutritional status, and postoperative complications of the two groups were compared and analysed. There was no significant difference in baseline characteristics and perioperative nutrition indicators between two groups. Postoperative hospital stay and the costs of nutrition support were significantly reduced in the EN group compared with PN group (P = 0.000). The times of first passing gas and bowel movement were shorter in the EN group compared with PN group (P = 0.001). The incidence of gastrointestinal complications was lower in the EN group compared with PN group (P = 0.039). For esophageal cancer patients with an NRS2002 score ≥ 3 and apparent difficulty swallowing, preoperative EN with a gastric tube is safe and easy to perform. Preoperative EN can shorten the recovery time of gastrointestinal function, reduce the incidence of gastrointestinal complications, finally accelerate postoperative recovery.
