What condition is characterized by common hepatic duct obstruction due to a gallstone impacted in the cystic duct?

The condition characterized by common hepatic duct obstruction due to a gallstone impacted in the cystic duct is known as Mirizzi's syndrome. This syndrome occurs when a gallstone becomes lodged in the cystic duct, leading to compression of the common hepatic duct and resulting in obstructive jaundice. The obstruction can cause inflammation and necessitates careful management to prevent complications.

In Mirizzi’s syndrome, the obstruction primarily arises from gallstones that are associated with the gallbladder, causing symptoms such as jaundice and biliary colic. This implies a distinct pathophysiology connected to the presence and location of the gallstone. This condition highlights the complex relationship between gallstones and hepatobiliary function, as well as the implications for surgical intervention.

Understanding Mirizzi's syndrome is crucial for accurate diagnosis and treatment, differentiating it from other gallbladder and biliary conditions. Patients exhibiting signs of biliary obstruction with a history of gallstones require thorough evaluation for this specific scenario.
