Mirizzi syndrome
Pronunciation: mi-RIT-see
Hepatic duct obstruction caused by impacted gallstone in the cystic duct or Hartmann's pouch.
Full Definition
A rare complication of gallstone disease where a large stone impacted in the cystic duct or Hartmann's pouch causes external compression of the common hepatic duct, leading to obstructive jaundice. Named after Pablo Mirizzi, the syndrome is classified into types I-IV based on the degree of cholecystoenteric fistula formation. Type I involves external compression only, while types II-IV involve progressively larger fistulous communications between the gallbladder and bile duct. This condition significantly complicates cholecystectomy and may require hepaticojejunostomy.
Usage
Usage note: Capitalize as it is an eponym; apostrophe in Mirizzi's is optional but maintain consistency.
