[Nutritional screening before surgery for esophageal cancer - current status and evaluation results]

The incidence of postoperative complications and mortality are usually higher in patients with preoperative malnutrition. Malnutrition often preexists, particularly in patients undergoing surgery for esophageal cancer, which is substantially invasive. It is therefore important to understand the nutritional condition of patients and actively control perioperative nutrition.Our hospital has been providing nutritional status screening for patients before resection of esophageal cancer, and we report the current status and evaluation results in this article.This screening included 158 patients requiring radical resection of esophageal cancer.Age, comorbidity with diabetes, body mass index(BMI), serum albumin(Alb), Onodera's prognostic nutritional index(PNI), and Glasgow prognostic score(GPS)were used as nutritional indicators to stratify patients for analysis.Evaluation parameters included the incidence of postoperative complications(any complication, pulmonary complications, psychiatric disorder, and anastomotic leakage)and rates of long-term postoperative hospitalization.The analysis indicated that age, BMI, serum Alb, PNI, and GPS are useful for predicting the onset of postoperative complications and prolonged postoperative hospitalization.For such patients, more active nutritional control should be provided.
