He performed a surgery,

他为阿什利做了手术
and I think medical scientists are still puzzled

我认为医学家现在依然困惑
whether this was some path-breaking surgery

这是一个具有里程碑意义的手术呢
or whether he just had good luck--that he'd helped Ashley.

还是运气使然让他救了阿什利一命
Ashley had a surplus production of his liver

阿什利患有肝囊肿
and he implanted a tube into his abdomen area

于是他在阿什利的腹部植入一根管子
to let this surplus flow out,

使过剩物质可以及时排出
and certainly Ashley felt much better after the surgery.

阿什利在手术之后感觉好多了
Well we know that occasionally

the doctors say the surgery was successful and the patient died.

Now this was a case when the patient was cured,

但这次我们的病人康复了
but we don't know whether the surgery had anything to do with it. Right?

可是我们不知道这是否和那次手术有关
