Obstructive jaundice occurs when the bile ducts are obstructed for any reason: (1) bile duct stones or gallbladder stones (Mirrizzi’s syndrome) obstruct the bile ducts and prevent bile from draining into the duodenum (3) Stenosis of the bile ducts due to inflammation or surgery; (4) Other conditions such as rare biliary hemobilia, where blood clots obstruct the bile ducts and cause jaundice; (5) Roundworms accidentally entering the bile ducts; (6) Medically induced bile duct injuries. Another malignant cause is: (1) malignant tumor of the bile duct itself or the gallbladder (cholangiocarcinoma); (2) cancer of the head of the pancreas; (3) cancer of the jugular abdomen, i.e., duodenal papilla; (4) blockage of the bile duct by a tumorthrombus of liver cancer; (5) obstruction of the bile duct by the enlarged lymph nodes adjacent to the bile duct in cancer patients.
