¹Cirrhosis: (+) referrs to macroscopic cirrhosis, which was diagnosed during surgery, (-) referrs to that we could not diagnose cirrhosis during surgery by naked eyes, however, it was diagnosed mild cirrhosis and hepatitis by microscopic pathology. The etiology of cirrhosis was hepatitis B virus infection in our series.
