This case report describes an accessory hepatic duct (AHD) identified
by intraoperative cholangiography during excisional surgery of a chole
dochal cyst (CC). The accessory duct was divided and reconstructed suc
cessfully to the Roux-en-Y jejunal loop. The postoperative course was
uneventful, and follow-up abdominal sonography revealed neither eviden
ce of biliary tract obstruction nor atrophic changes of the liver. It
is advocated that an AHD should be meticulously reconstructed if it is
divided during excisional surgery of a CC.
