Antenatal Diagnosis of Choledochal Cyst: A Case Report

膽管囊腫為罕見之先天性病灶。它主要造成新生兒間歇性的阻塞性黃疸。但部分患者在一開始並沒有症狀，直到十幾或二十多歲時才以典型的合併腹痛、右上腹部腫塊、及黃疸三種症狀表現出來。產科超音波檢查的進步已經使得包括膽管囊腫在內的許多先天異常能夠在患者胎兒時期即得到診斷。我們在此報告一例妊娠二十週診斷先天性膽管囊腫的病例，此病例於產後七個月大時接受手術治療。由本病例可以得知：儘早診斷並在新生兒時期就手術切除被公認為是膽管囊腫最好也最安全的處理方式，仔細的產前超音波檢查將有助於膽管囊腫的提早得到注意並對患者的預後有正面的幫助。

Choledochal cyst is a rare congenital lesion that can cause intermittent obstructive jaundice in the newborn. However, some patients with choledochal cyst remain asymptomatic until they present in the second or third decade of life with the classic triad of abdominal pain, right upper quadrant mass, and jaundice. Advances in obstetric ultrasonography have led to the incidental antenatal identification of a number of fetal disorders, including choledochal cysts. Here, we presented a case of choledochal cyst that was detected prenatally at 20 weeks of gestation. The patient underwent surgery at 7 months of age. In conclusion, early diagnosis and excision of the cyst in the newborn is considered to be the optimal treatment of choledochal cyst, and may pose less risk to the patient than delayed surgical intervention. Greater appreciation of the prenatal sonographic features of choledochal cysts may allow for earlier intervention in newborns and may favorably impact the prognosis.
