Mirizzi syndrome Type II (Csendes classification) is characterised by:
- A Extrinsic compression of the CHD by an impacted cystic duct stone without fistula
- B Cholecystocholedochal fistula involving more than two-thirds of the CHD circumference
- C Cholecystocholedochal fistula involving less than one-third of the CHD circumference ✓
- D Complete obliteration of the CHD with cholecystoduodenal fistula
Correct answer: C. Cholecystocholedochal fistula involving less than one-third of the CHD circumference
Explanation
The Csendes classification of Mirizzi syndrome: Type I — extrinsic compression by impacted cystic duct/Hartmann's pouch stone; Type II — cholecystocholedochal fistula <1/3 CHD circumference; Type III — fistula 1/3 to 2/3; Type IV — fistula >2/3 or complete CHD destruction; Type V — any type with cholecystoenteric fistula. Surgical complexity and reconstruction need increase with type. Type II can be managed with partial cholecystectomy and primary repair.
