Fig. 1A. 79-year-old woman with rare combination of biliary anomalies.
Photograph taken during pancreaticoduodenectomy shows biliary anomalies.
Gallbladder was removed, and cystic duct was ligated and divided proximal to
its junction with aberrant hepatic duct (white arrowhead). Common
hepatic duct (black arrow) and aberrant hepatic duct (white
arrow) were transected separately. Probe is inserted through stump of
aberrant hepatic duct. Pinhole bile leakage in gallbladder bed was sutured
(black arrowhead). CHA = common hepatic artery, RHA = replaced right
hepatic artery, P = body of pancreas, SMV = superior mesenteric vein.

Fig. 1B. 79-year-old woman with rare combination of biliary anomalies.
Operative cholangiogram obtained through stump of aberrant hepatic duct shows
that aberrant duct is cystohepatic duct. Thereafter, bile duct of Luschka
(asterisk) is visualized, followed by hepatic duct of right
paramedian sector and left hepatic duct. Sutured bile duct in gallbladder
fossa is branch of bile duct of Luschka (arrowhead). Arrows indicate
order of opacification. LHD = left hepatic duct, Para = hepatic duct of right
paramedian sector.

Fig. 1C. 79-year-old woman with rare combination of biliary anomalies.
Operative cholangiogram obtained through common hepatic duct shows hepatic
duct of right lateral sector, hepatic duct of right paramedian sector, and
left hepatic duct, in that order. Bile duct of Luschka is not visualized. Para
= hepatic duct of right paramedian sector, LHD = left hepatic duct, Lat =
hepatic duct of right lateral sector.

Fig. 1D. 79-year-old woman with rare combination of biliary anomalies.
Schema of biliary system shows bile duct of Luschka (asterisk) acting
as intrahepatic communicating branch between cystohepatic duct and hepatic
duct of right paramedian sector. Para = hepatic duct of right paramedian
sector, Lat = hepatic duct of right lateral sector, LHD = left hepatic duct,
CHD = common hepatic duct, GB = gallbladder.
