以經皮穿肝來處置膽道囊腫開刀後之膽管腸道吻合狹窄－－兩病例報告

Percutaneous Management to Choledocho-Enterostomy Stricture Resulted from Complication of Choledochal Cyst Excision

膽道囊腫為一先天性膽道疾病。臨床上並不多見，它好發於兒童及女性，開刀是主要治療方法。但開刀後的晚期併發症，包括膽管腸道吻合處狹窄，並非罕見。再次開刀是一個可接受的方法。但是對於手術高危險群或不願意開刀的病患，短期放置經皮穿肝引流管可成功解決吻合處狹窄，我們在此提出兩個治療成功的病例，以供參考。

Choledochal cysl is defined as a dilatation of some parts of the biliary tract that may include both intra-and extra-hepatic sites. The first, well-documented case was reported by Douglas in 1852. Choledochal cysts are rare, with a prevalence that ranges from I in 10.000 to 1 in 150,000 live births. These cysts are relatively more common in Japan and Asia, and are more often seen in females. Excision is now the treatment of choice, but postoperative complications such as anastomosis strictures, cholangitis, etc are not uncommon. Relieving, treating or bypassing the bilio-enterostorny stricture via surgery or stent implantation pose a challenge to clinicians. We present two cases of choledochal cysts which resulted in choledocho-enterostomy stricture and cholangitis following cyst excision, and which were successfully treated by plastic stent implantation.
