[Congenital dilatation of the choledocus. Diagnostic considerations and therapeutic indications]

From 1964 to 1979, 7 children affected by congenital choledocal cyst were operated on. A cysto-duodenostomy was performed in all cases but one, in whom an excision of the cyst was directly carried on. In the light of the this experience Authors conclude that direct excision is preferable rather than a cysto-duodenostomy and furthermore possible to be arrived at basically by means of ultrasound. This latter one is considered so far the best way to reach a pre-operative conceptualization of the pathology.
