Hello and hope you are doing well.
Cirrhosis, with a biopsy done and if the biopsy is positive for evidence of carcinoma, then surgical therapy is needed. Was he diagnosed with a tumor? Recovery will then be based on the extent of spread of the tumor and his general health and co morbid conditions like diabetes.
Hope this helped and do keep us posted.
Sorry to hear of the diagnosis... Unusual to do surgery for cirrhosis unless it is a biopsy.
If the surgery can be done through by laparoscopy (a scope), he should be up and around in a day or so. Same for a needle biopsy.
If it is an open procedure, he'll be hurting for a week, but getting around OK in 10 days or so. Probably no work for 3-4 weeks though.
Hope he does well. Best of luck to you both!
