Small studies suggest differences in efficacy and safety exist between olive oil-based and soybean oil-based parenteral nutrition regimens in hospitalized adult patients. A study in China suggested that olive oil-based parenteral nutrition provided effective nutrition, was well tolerated, was associated with fewer infections and conferred greater ease-of-use than soybean oil-based parenteral nutrition. The objectives of this study were to assess safety and efficacy of an ClinOleic-based lipid parenteral nutrition regimen compared with Structolipid-based lipid parenteral nutrition regimen in Chinese adults after pancreatectomy for whom oral or enteral nutrition was not possible, insufficient or contraindicated.
