Unlabelled: The aim of the present study has been to systematize the clinical presentation of the entity named choledochal cyst, in relation with its probable etiopathology and the intraoperative findings as well as its evolution after surgery, based on the revision of the literature and of our experience in 29 cases., Material and Methods: 29 cases of cystic dilatation of the biliar duct extra and/or intrahepatic are analyzed. In 4 cases the diagnosis was prenatal and two were excluded of the study after it has been confirmed they suffered biliary atresia type I. In the left 27 cases, 19 variables are analyzed retrospectively, like age, sex, weight, symptoms, ultrasonographic images, etc. Subsequently, intra-operative cholangiographic findings were correlated with the clinic presentation and the evolution of the patients after surgery., Results: Of the 27 cases analyzed 16 (59,25%) were cystic dilatations from which 14 had a neonatal or early clinic presentation (before 2 years), however the fusiform dilatations were presented later on. From the analyzed symptoms, in relation with the age only the pain and the jaundice showed significant differences, being the pain most frequent in later presentation ande the jaundice in the early form. The two cases of type 3 of Todani or choledochocele were of later presentation. An anomaly in the bilionpacreatric junction was detected in 15 patients; the majority had a later presentation, associated to pancreatitis in 4 cases. Primary cyst excision and biliary Roux-en-Y reconstruction was the treatment of election in the majority of cases. In 3 cases we used the appendix to replace the choledocus, but all three cases were reconverted two years later because of permanent elevation of ALT and GGT., Conclusions: In favour of the literature and of our experience nowadays it would be possible to systematize this malformation and make a division in two groups, depending on the cholangiographic findings and clinical presentation: 1. Cystic dilatations with a clinical neonatal presentation or beneath 2 years. 2. Fusiform dilatations with a later clinical predominance and associated frequently to pancreatitis and anomalous pancreatobiliary junction. Choledochocele is an entity that must be considered not only for its etiology but for its clinical presentation and treatment. Primary cyst excision and biliary Roux-en-Y reconstruction is the treatment of election. Regular long-term review of these patients is mandatory in the surveillance of sub-clinic cholangitis and the risk of possible long-term malignance of this entity.
