Hi adn welcome to HCM.
shouldnt be related to your LFT execpt in some autoimmune disorders
or after using specific drugs.. It is much more possible that Hepatitis
cause causes it. Hepatitis usually has phases in which your symptoms and liver enzymes from time to time show aggravations and improvement. Focus on your planned surgical procedures and after that you can manage your liver problem(u should do ultrasounds and viral markers in blood) and maybe start with interferon
Wish you good health.
