They may be "indicative of end-stage cirrhosis" but to my knowledge (and I'm not a medical professional but I did have to deal with this stuff), those indicators are not definitive.
As I said, my ex-husband's doctors were certain he would need a transplant, until the biopsy was performed several months later (my recollection was that they needed the ascites to resolve before they did the biopsy).
I emotionally prepared for the worst, and hoped for the best. The news we finally got was as hopeful as you can get.
If their prediction is accurate, the problem will be getting a transplant. Traditionally, alcoholic cirrhotics are not given the same priority for transplant as non-alcohlic sufferers of liver disease. I haven't looked at the current policies for transplants, so I don't know what the current sobriety requirments are.
