Final answer:
Obstruction of the common bile duct by stones, neoplasms, and spasms or strictures leads to obstructive or post-hepatic jaundice. This type of jaundice occurs when the flow of bile in the bile ducts is blocked, resulting in an increase in conjugated bilirubin in the blood.
Step-by-step explanation:
Obstruction of the common bile duct by stones, neoplasms, and spasms or strictures results in a classification of jaundice known as obstructive or post-hepatic jaundice. This type of jaundice occurs when the flow of bile in the bile ducts is blocked, leading to an increase in conjugated bilirubin in the blood.
For example, gallstones can block the bile duct and cause pain and jaundice. When a gallstone obstructs the bile duct, bilirubin cannot be excreted and backs up into the liver, leading to the characteristic yellow coloration of the skin and eyes.
Other conditions that can cause this type of obstruction include neoplasms (abnormal growths), spasms, and strictures (narrowing) of the common bile duct.
