Presentation
Complains of yellowish discolouration of eyes.
Patient Data
GB wall is mildly thickened with calculus at the cystic duct causing compression of the common bile duct with consequent mild intrahepatic biliary dilatation (Type-I).
Descent of pelvic floor with inferior displacement of the urinary bladder base and vesicoureteric junctions (cystocele) with mild bilateral hydroureteronephrosis.
Case Discussion
Mirizzi syndrome refers to compression of CBD or CHD from one or more calculi at the cystic duct or neck of gall bladder resulting in obstruction and jaundice. It is a functional hepatic syndrome but can often present with biliary duct dilatation and can mimic other hepatobiliary pathology such as cholangiocarcinoma.
Types of Mirizzi syndrome:
Type-I: external compression of common bile duct.
Type-II: cholecysto-biliary fistula is present with erosion of less than one third of the circumference of the bile duct.
Type-III:cholecysto-biliary fistula involving upto two third of the duct circumference.
Type-IV: cholecysto-biliary fistula causing complete destruction of bile duct.
