“…The biliary ductal system and its endings in the duodenum have been described in detail by Lassau and Hureau (1967), Boyden et al (1967), andO'Rahilly andMuller (1987). The gallbladder led directly to the intestine through the cystic and the future ductus choledocus (Fig.…”

“…However, the cavity between the orifices of the dorsal pancreas and common bile duct is completely obliterated for the active epithelial proliferation of the developing common bile duct. Between the end of the 7th and beginning of the 8th week, the bile duct develops two channels, and the ventral one continues into the lower segment [3,7,8]. Still in the 8th week, in the distal segment of the duodenum, two parallel channels and vacuoles are still present [6].…”

“…From the end of the 7th week to the 8th week, the duodenum increases in diameter and the vacuoles coalesce and begin to restore the patency of the lumen by epithelial proliferation and vacuolation [7,8]. The coalescence of vacuoles initially produces two parallel channels in the duodenum while, at the same time, two channels appear in the developing biliary system, each of which joins up separately with the two duodenal channels [6,8]. From the early 8th week to the 12th week, hepatopancreatic ducts have both superior and inferior orifices.…”

A hepatic diverticulum appears in the ventral wall of the primitive midgut early in the 4th week of intrauterine life in the development of the human embryo. This small diverticulum is the anlage for the development of the liver, extrahepatic biliary ducts, gallbladder, and ventral pancreas. By the 5th week, all elements of the biliary tree are recognizable. Marked elongation of the common duct occurs with plugging of the lumen by epithelial cells. Recanalization of the lumen of the common duct starts at the end of the 5th week and moves slowly distally. By the 6th week, the common duct and ventral pancreatic bud rotate 180° clockwise around the duodenum. Early in the 7th week, the bile and pancreatic ducts end in closed cavities of the duodenum. Between the early 8th and 12th week, hepatopancreatic ducts have both superior and inferior orifices. Of these two orifices, the inferior one is usually suppressed. The muscle of the sphincter of Oddi develops from a concentric ring of mesenchyme surrounding the preampullary portion of the bile and pancreatic ducts. At about the 10th week, the muscle of the sphincter of Oddi undergoes differentiation. In the 16th week, the muscularis propria extends from just outside the fenestra to the upper end of the ampulla. By the 28th week, the musculus proprius is differentiated almost to the distal end of the ampulla.

“…Separate openings of the biliary and pancreatic ducts have been described in cases of duodenal atresia in 1906 by Kapa and in 1930 by Katz [14], Embryologic studies have since shown that the hepatopancreatic duct acquires two separate openings in the coalescing duodenal vacuoles during its formation. A similar bifid orifice occurs at the end of the accessory pancreatic duct [15], These stages in development are temporary, but normal, and might provide a basis in explaining findings such as double papilla. The clinical significance of such a malformation was related in our cases more to the associated biliary reflux than to the separate openings of the biliary and pancreatic ducts.…”

Variation in the normal duodenal papilla is common. The gross endoscopic appearances are usually not related to the frequent variations in the manner of confluence of the biliary and pancreatic ducts in the sphincter of Oddi. Malformation of the papilla of Vater is however rare. We describe 2 cases of duplication with separated biliary and pancreatic orifices. Incompetence of the biliary orifice and duodenobiliary reflux was associated in one case with recurring cholangitis. Embryology provides an explanation for this rare malformation, as the hepatopancreatic duct acquires temporarily two separate openings in the coalescing vacuoles of the duodenum during its formation. This malformation must be distinguished from acquired choledochoduodenal fistula. Its clinical significance is related to the presence or absence of duodenobiliary reflux.
