Abstract
One hundred and twenty-eight fowls of various breeds were dissected topresent diagrammatically the distribution of the pancreatic ducts in relation to the lobulaLion and the variation of the sites at which the ducts penetrate the serous surface of theduodenum.Some kinds of colored radiopaque fluids for radiography and color photography wereinjected into the three pancreatic ducts respectively to elucidate the pattern of distributionof the ducts (Figs. 26, 27).The pancreas of the fowl consists of three main lobes, Lobus dorsalis (Ld), Lobusventralis (Lv) and Lobus lienalis pancreatis (Lip). Each of the dorsal and ventral lobes issubdivided into two parts, Pars dorsalis (Pd) and Pars ventralis (Pv), by an incision towhich the Ligamentum pancreaticoduodenale terminates (Figs. 1 -4).The three pancreatic ducts, Ductus pancreaticus dorsalis (Dpd), Ductus pancreaticusventralis (Dpv) and Ductus pancreaticus accessorius (Dpa), were demonstrated constantly inall the cases, except one (Figs. 5, 6).Considerable variations were observed on the distribution of ducts in the parenchyma(Figs. 7-18) and on the terminations of ducts on the serous surface of the duodenum(Figs. 19 -25). They were grouped into three types. The correlations between the typesand the breeds used are shown in Tables 1 and 2..Three pancreatic ducts entered the duodenum at a site close by two bite ducts. Theyopened into a common papilla, Papilla duodeni communis (Fig. 28).The nomenclature Of the lobes and dUCtS glV(611 111 lmterature and that pTOpOsed by theauthors are summarized in Tables 3 and 4.
