Original Communication Clinical Relevancy Statement

The immunomodulation of nutrition support supplemented with ω-3 fatty acids has been more widely used in elective gastrointestinal surgery, and the clinical trials on ω-3 fatty acids in patients receiving pancreaticoduodenectomy (PD) are scarce. The results of this study have shown that parenteral fish oil lipid emulsion in parenteral nutrition supplementation combined with enteral nutrition support can greatly improve the nutrition state and liver function of patients, decrease the incidence of infectious morbidities, and shorten the postopera-tive hospital stay. These findings are clinically relevant for guiding surgeons in perioperative medications in PD
