Marked elevation of serum transaminase activity associated with extrahepatic biliary tract disease.

Nine patients with choledocholithiasis or cholelithiasis developed transient elevations of serum glutamic oxalacetic transaminase (SGOT) levels of greater than 600 units. Awareness of such transient biliary disease will prevent an unnecessary evaluation of a primary hepatocellular disorder. In our study, we concluded that 1) The SGOT level rose and fell rapidly within a 24- to 72-hour period. 2) Higher SGOT levels were seen in patients with choledocholithiasis in whom the gallbladder had been removed. 3) In patients with choledocholithiasis a fall in SGOT level did not necessarily mean the stone had passed.
