This terminology acknowledges that the embyronic development of the hepatic diverticulum (which becomes the liver, gall bladder, and pancreas) had formed properly in the past. It may be that at some point in its maturation into the major duodenal papilla the diverticulum closes. "The initial site of origin of the hepatic diverticulum is from the ventral side of the foregut. As the duodenum differentiates, unequal growth in the wall adjacent to where the hepatic diverticulum was located brings the origin of the diverticulum, now the entrance of the bile duct (thhe major duodenal papilla), to the dorsal surface of the duodenum..."
