Rachelsmom, welcome to the forum! I am so sorry that your dad is so sick. I also have hep C, diagnosed in '93, and am a liver cancer survivor. I have been to Jackson Memorial, myself, when I lived in Miami years ago. Your dad may be a candidate for a liver transplant. Due to his condition, they may fast-track him through the evaluation process.
I suggest you read through some of the other threads here, as well as the information in the folder, Hepatitis Resources, at the top of the forum page. You will get a lot of information that way.
We are not doctors, and even doctors have a hard time giving an estimate as to how long a person with liver disease will live, as it's such an individualistic disease. Ascites is not life-threatening. Most liver disease patients have it and it is managed with diuretics and draining of the fluid, and sometimes a TIPS procedure to shunt the fluid. The blocked bile duct is more serious. They will have to determine if he is stable enough to undergo surgery to remove his gall bladder, or if they should try to get him on a liver transplant list and remove it at the time of transplant. The gall bladder is attached to the underside of the rt. lobe of the liver. I had mine removed when the rt. lobe of my liver was removed due to cancer, and I can't tell the difference.
Your father certainly has our prayers.
