The authors report 3 observations of late stenosis of the intermediate extrahepatic hile duct, following operations in which the continuity of the bile duct was not interrupted. The clínica] signs occurred late and they suggested completely different pictures to trose found in the surgical act. All of them were fibro-sclerotic strictures of the hepato-cystic-choledochus confluence, non-neoplasic, and without any apparent etiological cause. They were solved by biliary-digestive derivation or end-to-end reconstruction of the bile duct when both ductal ends were of a similar caliber. Atube was always placed through the anastomosis, to act as a stent of it 

Se presentan 3 observaciones de estenosis tardía de la via biliar extrahepática intermedia, consecutivas a operaciones en las cuales la continuidad de la vía biliar no fue interrumpida. Las manifestaciones clínicas aparecidas tardíamente, sugirieron cuadros completamente diferentes a los hallados en el acto operatorio; Todas se trataronde estenosis fibro-escleróticas del confluente hepatocisticocoledociane, no neoplásicas y sin ningunacausa etiológica demostrable. Se solucionaron mediante derivación biliodigestiva o reconstrucción terminoterminal de la vía biliar cuando los cabos fueron de calibre similar, montadas sobre tubos calibradores en todos los casos.
