Effect of parenteral fish oil lipid emulsion in parenteral nutrition supplementation combined with enteral nutrition support in patients undergoing pancreaticoduodenectomy.

BACKGROUND: The effect of parenteral fish oil lipid emulsion in parenteral nutrition (PN) supplementation combined with enteral nutrition (EN) support on pancreaticoduodenectomy (PD) was investigated with a randomized controlled clinical trial at the Affiliated Drum Tower Hospital.

MATERIALS AND METHODS: Seventy-six patients who underwent PD in the Department of Hepatobiliary Surgery were randomly divided into 2 groups: the polyunsaturated fatty acid (PUFA) group (n = 38) and control group (n = 38). Patients in the PUFA group received parenteral fish oil lipid emulsion supplementation combined with early EN support for 5 days after PD. Venous blood samples were obtained for assay on the day before surgery and on day 6 after surgery.

RESULTS: Compared with the results of the control group, a significant difference was seen in the extent of the decrease in total protein and prealbumin in the PUFA group (P < .05). Alanine aminotransferase (ALT), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) were significantly decreased on day 6 in the PUFA group (P < .01), and a significant difference was seen in the extent of decrease in ALT, AST, and LDH in the PUFA group (P < .05). The ratio of infectious complications in the PUFA group was significantly decreased, as well as the postoperative hospital stay (P < .05), and there was no hospital mortality in this study.

CONCLUSION: Parenteral fish oil lipid emulsion in PN supplementation combined with EN support can greatly improve the nutrition state and liver function of patients, decrease the incidence of infectious morbidities, and shorten the postoperative hospital stay.
