Objective To compare the clinical efficacy between total enteral nutrition and enteral nutrition combined with parenteral nutrition after pancreaticoduodenectomy. Methods A total of 70 patients who underwent pancreaticoduodenectomy in our hospital from July 2012 to July 2015 were collected prospectively, and all patients were divided into 2 groups randomly: enteral nutrition group and combined nutrition group. Patients in enteral nutrition group received total enteral nutrition, and patients in combined nutrition group received enteral nutrition combined with parenteral nutrition. Compared the nutritional indicators, other related indexes, and morbidity between the 2 groups. Results ① The nutritional indexes. Compared with before treatment, the body mass index (BMI), white blood cell count, serum albumin level, serum albumin level, and total lymphocyte count at 1 week and 2 weeks after treatment improved (P<0.05). At the same time point (before treatment, 1 week after treatment, and 2 weeks after treatment), there was no significant in the BMI, white blood cell count, serum albumin level, serum albumin level, and total lymphocyte count between the 2 groups (P>0.05). ② Other related indexes. The anal exhaust time, defecation time, and hospital stay of the patients in the combined nutrition group were shorter than those of enteral nutrition group, and the cost of treatment in combined nutrition group was less than that of the enteral nutrition group (P<0.05). ③ Morbidity. There was no significant difference in the total morbidity between the combined nutrition group〔11.4% (4/35)〕 and enteral nutrition group 〔20.0% (7/35)〕,P>0.05. Conclusion Total enteral nutrition and enteral nutrition combined with parenteral nutrition after pancreaticoduodenectomy both can obtain well curative effect, but enteral nutrition combined with parenteral nutrition can make the patients recover faster with lower cost, which is suitable for promotion.
