Timing of operation in children with a prenatal diagnosis of choledochal cyst: A single-center retrospective study.

We maintain that it is advantageous to receive surgical treatment in the asymptomatic period for patients with a prenatally diagnosed CDC. A cyst size of length >5.2 cm and width >4.1 cm suggested that clinical symptoms might appear, and that surgery should be carried out as soon as possible, even in the neonatal period.
