Resumo
It was studied, the biliary ducts in 30 livers from swines Landrace breed removed adults (15 males and 15 females), by means of the use of radiography, dissection anda partial corrosion. The results discriminated down were obtained. The ductus choledocus, always free of the tributaries, resulted of the fusion: of the ductus hepaticus and ductus cysticus (66.7%); ramus principalis dexter and ramus principalis sinister (16.7%); ductus hepaticus and the more ordinary trunk formed by ductus cysticus and ramus lobi dextri medialis (1 0 .0 %); ramus principalis dexter, ramus principalis sinister and ductus cysticus (3.3%); of the first two branches plus the ductus cysticus and ramus lobi dextri medialis (33%) in one covergence triple. The ductus hepaticus was identified in 23 of the 30 preparations (76.7%); 17 of them (56.7%) appeared free of afluents while in other more 6 (2 0 .0 %) joined it the ramus lobi dextri medialis (133%) this branch plus a contingent of the lobus dexter medialis, in the piece remaining (33%). The ductus cysticus, free in 29 out of 30 cases (96.7%), receiveing in the other, an efferent of the lobus dexter medialis (33%); participated of ductus choledocus formation in 25 of them (83.3%) and, compose the system of ramus principalis dexter in the remaining (16.7%). The system of the ramus principalis dexter is composed by the ramus dorsomedialis lobi dextri latEstudou-se o sistema bilífero de 30 suínos da raça Landrace, (15 machos e 15 fêmeas), adultos, mediante o uso de radiografias, dissecção e corrosão parcial. Chegamos aos resultados abaixo discriminados. O ductus eholedocus, sempre livre de tributários, resulta da fusão:do ductus hepaticus e ductus cysticus (66,7%);ramus principalis dexter e ramus principalis sinister (16,7%); ductus hepaticus mais tronco comum formado pelo ductus cysticus e ramus lobi dextri medialis (1 0 ,0 %); ramus prindpalis dexter, ramus principalis sinister e ductus cysticus (3,3%); dos dois primeiros ramos mais a via configurada pelo ductus cysticus e ramus lobi dextri medialis (3,3%), em tríplice convergência. O ductus hepaticus acha-se identificado em 23 das 30 preparações (76,7%); 7 delas (56,7%) exibem-no livre de afluentes, enquanto nas mais 6 (20%) a ele se juntam o ramus lobi dextri medialis (13,3%Jjeste ramo mais um contingente do lobus dexter medialis, (3,3%). O ductus cysticus, livre em 29 dos 30 casos (96,7%), recebe no outro, um eferente do lobus dexter medialis (3,3%); participa da formação do ductus choledocus, em 25 deles (83,3%) e compõem o sistema do ramus principalis dexter, nos demais (16,7%). Compõem o sistema do ramus prindpalis dexter, o ramus dorsomedialis lobi dextri lateralis (1 0 0 ,0 %), o ramus ventromedialis lobi dextri lateralis (1 0 0 ,0 %), o ramus ventralis lobi dextri la
