Dear sagar, as I understand you are concerned about your sgpt levels. I dont think taht it is asociated with your previous surgery except some kind of liver blood vessels and bile ducts were injured.
SGPT is elevated in hepatitis, diabetes, congestive heart failure
, liver damage
, bile duct problems, infectious mononucleosis
and the best way to rule these disorders out is to do ultrasound
or CT scan of liver. Also liver biopsy
can be done. But mildly elevation of SGPT only isnt something to be concerned about and it is not a threatening for your life . You should check your bilirubin levels and red cells count too.
Wish you good health. DR ivan Romic
