We recently experienced a high frequency of biliary complications after orthotopic liver transplantation in rats (22 of 25 cases (88%): biloma, 20 cases; biliary peritonitis, 2 cases). These complications seemed to be rare in general, but some researchers reported such cases and addressed them mainly through rearterialization. The biliary complications we encountered were found to be associated with necrosis of the donor bile duct and an opportunistic infection of Enterobacteriaceae. After administering appropriate antibiotics, the complications significantly diminished (2 of 25 cases (8%), P = 0.0001). The nonarterialized bile duct, which becomes ischemic soon after liver transplantation, appears to be susceptible to infections. Such opportunistic infections may prevent the development of arterial collaterals, causing bile duct necrosis and the subsequent leakage of bile juice. When biliary complications frequently occur after nonarterialized liver transplantation in rats, the possibility of an opportunistic infection should thus be considered.

UI	MeSH Term	Description	Entries
D009336	Necrosis	The death of cells in an organ or tissue due to disease, injury or failure of the blood supply.
D009894	Opportunistic Infections	An infection caused by an organism which becomes pathogenic under certain conditions, e.g., during immunosuppression.	Infection, Opportunistic,Infections, Opportunistic,Opportunistic Infection
D010406	Penicillins	A group of antibiotics that contain 6-aminopenicillanic acid with a side chain attached to the 6-amino group. The penicillin nucleus is the chief structural requirement for biological activity. The side-chain structure determines many of the antibacterial and pharmacological characteristics.

D010878	Piperacillin	Semisynthetic, broad-spectrum, AMPICILLIN derived ureidopenicillin antibiotic proposed for PSEUDOMONAS infections. It is also used in combination with other antibiotics.

D002511	Cephalosporins	A group of broad-spectrum antibiotics first isolated from the Mediterranean fungus ACREMONIUM. They contain the beta-lactam moiety thia-azabicyclo-octenecarboxylic acid also called 7-aminocephalosporanic acid.
