Summary: | A study in 38 liver of adults ducks from Jundiaí, state of São Paulo, was developed. After injection of Neoprene latex 650 colored by green and fixation in aqueous 10% formalin, the material was dissected under dental loupe, photographed and sketched. The intra hepatic bile ducts of the left lobe showed up in 76.3% the samples consisting of three collecting ducts bile; and 23.7% of the cases, there was the presence of one collector originated from caudal segment, draining to the hepatic duodenal duct. In the right lobe, in 100% of samples, were four collecting duct segments: cranium medial superficial, cranium medial deep, lateral and caudal (ventral caudal). With regard to biliary extra hepatic in 36 samples(94.7%) it was composed of three ducts visible in hepatic hilum: hepatic duodenal, hepatic cystic and cystic duodenal. In two samples (5.3%) was not observed hepatic cystic duct. The hepatic duodenal ductand cystic duodenal duct in 100% of the samples, they reached the duodenum. In six samples (15.8 %), besides the hepatic cystic duct, the gallbladder was achieved directly by bile collecting ducts of the right lobe. The gallbladder was not achieved by hepatic cystic duct in two samples (5.3 %). As vias biliares intra e extra-hepáticas de 38 marrecos-de-pequim adultos, provenientes de Jundiaí,estado de São Paulo, após injeção de Neoprene Látex 650 corado de verde e fixação em solução aquosa de formol a 10%, foram dissecados sob lupa odontológica, fotografados e desenhados esquematicamente. A via biliar intra-hepática no lobo esquerdo mostrou-se constituída por três ductos coletores biliares em 76,3% das amostras e, em 23,7% dos casos, está presente um quarto coletor, originado no segmentocaudal, drenando para o ducto hepatoduodenal. No lobo direito, em 100% das amostras ocorreram quatro ductos coletores dos segmentos craniomedial superficial, craniomedial profundo, lateral e caudal (ventrocaudal). No que se refere à via biliar extra-hepática, ela esteve constituída por três ductos visíveis no hilo hepático em 36 amostras (94,7%): hepatoduodenal, hepatocístico e císticoduodenal.Em duas amostras (5,3%) não foi observado o ducto hepatocístico. Em 100% das peças, os ductos hepatoduodenal e císticoduodenal, alcançaram o duodeno. Em seis amostras (15,8%), além do ductohepatocístico, a vesícula biliar foi alcançada diretamente por ductos coletores biliares do lobo direito. A vesícula biliar não foi alcançada pelo ducto hepatocístico em duas peças (5,3%). |
