Your father has an umbilical hernia which is fairly common in people that have cirrhosis along with a lot of fluid retention in the abdomen. There is not a whole lot they can do for your father at this time other than treat his symptoms of cirrhosis since there is no cure other than a transplant. Surgery can be done on the hernia if it gets too bad.
From what you have said, it sounds like your father is in the more advanced stage of cirrhosis, but his doctor should be the one to tell you how much damage has already been done to his liver. Once the damage gets severe, there is nothing that will stop the disease from progressing, but it can be slowed down by avoiding alcohol if that is what caused his cirrhosis.
Cirrhosis is usually a slow disease that eventually leads to total failure, but a crisis can happen at any time which can be life threatening and emergency treatment is needed. An example would be that those with cirrhosis develop unwanted veins called varices due to poor liver function. These veins are not like the ones we are born with. They are weak and can leak or burst which causes internal bleeding. If the varice was very large, a person can actually bleed to death if not caught in time. Also, the fluid that accumulates in the abdomen can become infected which can also be life threatening. All the symptoms of cirrhosis just keeps getting worse and worse as time goes on until the end. A procedure called banding can be done to those veins to help lower the risk of any bleeding. They do an endoscopy and locate the vein, tie it off with what looks like a fat rubber band. The vein will die in a few days which means it cannot bleed. I used to get mine checked every 3-6 months when I had cirrhosis.
Your father should talk to his doctor about a possible transplant for himself if he is committed to getting well again and possibly saving his life. Transplant centers requires 6 months of proven sobriety and he must do everything they tell him to do. Then he will have to go through a transplant evaluation to see if he would be a good candidate. A board of doctors and medical professionals will get together and go over his case from the evaluation and decide whether or not he can get listed for a transplant. My friends husband who is an alcoholic for over 20 years just recently got his transplant and is doing good today.
Your father is young yet and should really try and check into this for himself. Without it, I don't think he is going to have much of a future with his cirrhosis other than a lot of misery till the end. His symptoms will just continue to get worse as I mentioned before and he will become increasingly sick. I hate being so blunt, but that is the reality of this disease. Your father really doesn't need anyone to sugar coat it at this late stage because he needs to get on the ball and try to get himself some help before it is too late. Good luck to you and your father in doing just that, getting help.
I had cirrhosis (autoimmune disease) and a liver transplant plus I'm a nurse.
