[A new case of a rare anomaly of the biliary tract]. / Un nuevo caso de una rara anomalía de las vías biliares.

We present a 36 year-old female with jaundice, who underwent surgical exploration with the diagnosis of probable biliary fasciolosis vs. Mirizzi´s syndrome. At surgery we found a short common duct leading to the body of gallbladder followed by a long cystic duct draining into the duodenum. Patient underwent hepaticojejunostomy with a Roux Y. The suspicious images of fasciola corresponded to inflammatory nodes in the hepatic hilium. A literature review was conducted and we found very few cases with this rare anomaly, some of them were managed with preservation of a portion of the gallbladder. We discuss the possible implications of this treatment and present an alternative management.
