  Omega-3 group

  All patients received TPN for 5 days postoperatively, according to a standard protocol: 3 g/kg BW glucose (5% Dextrose in Ringer's Lactate, Biosel, Istanbul), 1.2 g/kg BW amino acids (Aminosteril 10%, Fresenius-Kabi) and 0.8 g/kg BW omega-6 fatty acids (Lipovenoes® 10%, Fresenius-Kabi) were provided to both groups through an indwelling central venous catheter. In the omega-3 group, the lipid content of TPN was replaced partially by omega-3 fatty acids (Omegaven®, Fresenius-Kabi) up to 0.2 g/kg BW per day.

  Drug: Lipovenoes® 10% and Omegaven®,
