What Causes Jaundice Plus Raise In Bilirubin And ALT Levels Post Appendectomy?

Can appendectomy be linked to liver disease? I had one last year and now am undergoing liver investigations. I have jaundice and elevated bilirubin and ALT. They can t seem to find out what is wrong. They have ruled out hep a b c and a number of other possibilities. I am currently wearing biopsy results. I am a healthy 31 year old female, no drugs alcohol or smoking, healthy eating and regular exercise.
