Background The aim of this study was to investigate factors associated with the development of parenteral nutrition‐associated liver disease (PNALD) and to examine the clinicopathological relationship of PNALD in extremely low‐birthweight infants (ELBWI). Methods The subjects were 13 ELBWI who had received PN because of intestinal perforation or functional ileus between 2000 and 2013. We measured the serum levels of biochemical parameters, including aspartate aminotransferase, alanine aminotransferase, and direct bilirubin. Liver histopathology was examined in relation to outcome. The subjects were categorized into two groups on liver histopathology: F(+), development of hepatic fibrosis and necrosis with/without cholestasis; and F(−), no hepatic fibrosis. Results Of 13 ELBWI, five died of hepatic failure, five died of sepsis, and the other three were alive at the time of the study. Of the five infants who died of hepatic failure, two developed fulminant hepatitis without cholestasis, and the other three developed chronic cholestasis and finally hepatic failure. Postmortem histopathology in F(+) indicated not only massive hepatic necrosis, but also massive hepatic fibrosis. These histopathological findings explained the clinical presentation of portal hypertension. There were significant differences in the fasting period after intestinal disease onset between the two groups. Conclusion The prolonged fasting with PN is responsible for severe hepatocellular necrosis with fibrosis and consequent lethal portal hypertension.
