The association between choledochal cysts and pregnancy is unlikely to be etiological, but may rather be an aggravation or precipitation o a preexisting condition. Although choledochal cysts rarely occur in pregnancy, the aim of this study is to
elucidate the condition associated with pregnancy because delayed or inappropriate therapy may be catastrophic for both mother and child.
