Mirizzi’s syndrome is a rare cause of acquired jaundice. It is caused by chronic cholecystitis and large gallstones resulting in compression of the common hepatic duct.
Pathophysiology
Multiple and large gallstones can reside chronically in the Hartmann’s pouch of the gallbladder, causing inflammation, necrosis, scarring and ultimately fistula formation into the adjacent common hepatic duct (CHD). As a result, the CHD becomes obstructed by either scar or stone, resulting in jaundice. It can be divided into four types.
Type I – No fistula present
Type IA – Presence of the cystic duct
Type IB – Obliteration of the cystic duct
Types II-IV – Fistula present
Type II – Defect smaller than 33% of the CBD diameter
Type III – Defect 33-66% of the CBD diameter
Type IV – Defect larger than 66% of the CBD diameter
