Both benign (adenomas) and malignant (ampullary carcinoma) tumors of the ampulla of Vater can cause biliary obstruction.
Carcinoma of the pancreas’ head can manifest with painless jaundice resulting from obstruction of the bile duct as it passes through the pancreas head. Benign pancreatic disorders such as chronic pancreatitis and pancreatic pseudocyst can also cause Cholestasis.

Cholestasis can be seen in AIDS as a result of biliary ductal changes viewed on a cholangiogram that look like primary sclerosing cholangitis.
Various parasitic infections, such as Ascaris spp and Strongyloides and liver flukes, such as Fasciola hepatica and Opisthorchis Sinensis, can cause extrahepatic biliary obstruction.
