胆道闭锁(BA)是一种病因不明的进展性炎性疾病,可导致肝硬化,最终肝衰竭。Kasai手术是BA患儿的首选外科治疗方法,当胆汁引流不能恢复或出现肝硬化的并发症时才行肝移植。Kasai手术的应用极大地改善了BA的预后。许多因素可影响Kasai手术的预后,这些因素相辅相成,但很少是绝对的影响因素,大多是相对的影响因素。 Biliary atresia (BA) is a progressive, inflammatory disease of unknown etiology that leads to cirrhosis and eventually liver failure. Kasai surgery is the surgical treatment of choice for children with BA and undergoes liver transplantation only when biliary drainage is not recoverable or complications of cirrhosis develop. The use of Kasai surgery has greatly improved the prognosis of BA. Many factors can affect the prognosis of Kasai surgery, these factors complement each other, but rarely absolute factors, mostly relative factors.
