Is it interesting to note that comparing patients with choledocholithiasis and without choledocholithiasis, the median AST and ALT values which are traditionally markers for hepatocellular injury were deranged to a much larger extent (7.2x-7.8x) than ALP and GGT (1.2x-5.6x), which usually demonstrates biliary epithelial damage. Here, GPT is linked to choledocholithiasis.
