Assessing the nutritional status of patients with gastric cancer by patient-generated subjective global assessment and its relationship with postoperative results / 国际外科学杂志

ABSTRACT

Objective To evaluate the preoperative nutritional status of patients with gastric cancer by using patient-generated subjective global assessment (PG-SGA) its relationship with postoperative results.Methods Make a preoperative nutrition assessment by using PG-SGA for 87 patients with gastric carcinoma who can be treated with operation.Analyze the effects of the postoperative complication,survival rate and the hospitalization time on patients.Results The number of patients of this group who can process the preoperative nutrition assessment by using PG-SGA accounts for 100％ of the total.There are 37 patients with moderate or severe malnutrition before operation (account for 39.1％).The complication incidence of patients with moderate or severe malnutrition before operation and the patients with no or mild malnutrition are 52.9％ and 5.7％ separately (P ＜ 0.01).The sensitivity and specificity of PG-SGA score for predicting complications are 85.7％ and 75.8％ respectively.And we should implement the analysis of regression to verify that the PG-SGA grade is the independent risk factor of postoperative complication by applying multiple Logistic(P ＜ 0.01).The average hospital stays of patients with moderate or severe malnutrition before operation and the patients with no or mild malnutrition are (21 ± 6) d and (16 ± 4) d separately (P ＜ 0.01).Conclusion According to the PC-SCA results,patients with moderate or severe malnutrition before operation have increased susceptibility to complication and the extension of hospital stays after the operatiou.Therefore,it is important to supply the proper nutrition support to these patients.
