To compare the efficiency of nutritional risk screening 2002 (NRS2002) and patient-generated subjective global assessment (PG-SGA) in hepatectomy for hepatocellular carcinoma (HCC) under the model of enhanced recovery after surgery (ERAS).

Clinical data of 90 patients undergoing hepatectomy in Nanjing Drum Tower Hospital from January 2014 to July 2018 were retrospectively analyzed. Among them, 75 patients were male and 15 female, aged 35-74 years old with a median age of 60 years old. The informed consents of all patients were obtained and the local ethical committee approval was received. Prior to surgery, all patients were divided into the malnutrition risk and normal nutrition groups according to the NRS2002 and PG-SGA scores. The nutritional indexes between two groups were statistically compared by t test. The incidence of postoperative complications was compared by Chi-square test or Fisher's exact probability test.

The preoperative average grip strength in NRS2002 malnutrition risk group was (29±8) kg, significantly less than (34±7) kg in normal nutrition group (t=-2.364, P<0.05). The incidence of postoperative complications in NRS2002 malnutrition risk group was 73%(11/15) and the incidence of pulmonary infection was 27%(4/15), significantly higher compared with 43%(32/75) and 4%(3/75) in normal nutrition group (χ2=4.712, 8.954; P<0.05). The incidence of postoperative pulmonary infection in malnutrition risk group by PG-SGA was 15%(3/20), significantly higher than 6%(4/70) in the normal nutrition group (χ2=0.041, P<0.05).

Compared with PG-SGA score, preoperative NRS2002 score can more accurately reflect the preoperative nutritional status of patients and more effectively predict the risk of postoperative complications under the model of ERAS of hepatectomy.
