Abstract: | The congenital anomaly in which the gallbladder is found on the left of the round and falciform ligaments (left-sided gallbladder)
is rare. We report two patients with left-sided gallbladder in whom intrahepatic portal venous anomalies were identified.
Computed tomography and intraoperative ultrasonography were used to define the portal venous anomaly. A long straight left
main portal vein was demonstrated, which did not have the typical umbilical portion. The right anterior segmental portal branch
(case 1), or the right main portal vein (case 2) were shown to course in a ventral direction and terminate as a cul de sac.
The round ligament (right round ligament) was attached to this venous termination, forming the right umbilical portion. The
left medial segmental portal venous branches originated from the right umbilical portion, and coursed to the left. In contrast,
cholangiography disclosed that the left medial segmental bile duct coursed to the right after arising from the left hepatic
duct (case 1), or the common hepatic duct (case 2). The essence of this anomalous condition is not a left-sided gallbladder,
but a right round ligament, which is an embryologic abnormality of the umbilical vein. A review of the English language literature
revealed no reports of left-sided gallbladder with intrahepatic portal venous anomalies. |
