Background/aims: Intravenous lipid emulsions may contribute to the development of total parenteral nutrition (TPN)--induced hepatobiliary complications.
Methods: In a prospective, randomised setting the authors compared the short-term hepatic effects of medium-chain triglycerides/short-chain triglycerides (MCT/LCT) physical mixture with a four-component intravenous (i.v.) lipid emulsion (LCT, MCT, Olive-oil and Fish-oil) in patients undergoing elective gastrointestial surgery during the early postoperative period.
Results: The authors demonstrated that total and conjugated bilirubin, alkaline phosphatase, alanine aminotransferase, aspartate amino transferase and cholinesterase did not change significantly during the 5-days observation period. In contrast to this, gamma-glutamyl transferase (GGT) activity increased by 2,4 times during 5-days therapy with the lipid emulsions mentioned above (SMOF lipid: 21,9 to 52,9 U/L, Lipofundin: from 32,5 to 79,6 U/L).
Conclusion: during a 4-days administration hepatic effect of the intravenous lipid emulsions did not differ significantly. The changes in enzyme levels confirm the cholestatic type of hepatobiliary deviations without clinical impact on short-term TPN therapy.
