Fistulogram through the umbilical fistula showing communication with the common bile duct (CBD), ventro-dorsal view, in a 1-year-old male French Bulldog. It is possible to observe the aberrant bile duct (ABD) meeting the CBD, after the left and right hepatic duct (LHD and RHD, respectively) gathering. The spread of contrast to the gastro-intestinal tract (stomach, duodenum, and jejunum) can also be observed.
