Background
- Refers to a rise in ALP and GGT +/- bilirubin that is much more pronounced than any rise in ALT
Differential Diagnosis
Marked Elevation
- Extrhepatic biliary obstruction
- Choledocholithiasis
- Cancer of the pancreas, gallbladder, ampulla of Vater, biliary duct, or perihilar lymph nodes
- Biliary strictures
- Primary sclerosing cholangitis with extrahepatic bile duct stricture
- Procedural complication of ERCP
- Chronic pancreatitis resulting in stricture of the distal bile duct
- Anastomotic stricture of the bile duct after liver transplantation
- Infection: AIDS cholangiopathy, Ascaris lumbricoides, liver fluke
- Intrahepatic cholestasis
- Drugs and toxins
- Primary biliary cholangitis
- Primary sclerosing cholangitis
- Intrahepatic cholestasis of pregnancy
- Benign postoperative cholestasis
- Total parenteral nutrition
- Infiltrative diseases: amyloidosis, lymphoma, sarcoidosis, tuberculosis, or hepatic abscess
- Liver metastases
- Allograft rejection after liver transplant
- Alcoholic hepatitis
