Mirizzi Syndrome An Uncommon Gallstone Complication
Dr. Ma Ka Wing

Common gallstone complications
What is Mirizzi syndrome ?
the gallstone impacted at the gallbladder neck/Hartmann’s pouch
Causing chronic inflammation and fibrosis
Result in obstruction or erosion of the common duct
How uncommon is it?
Variable, from 0.3% to 3% of patients having cholecystectomy
More common in South America
Who is Mirizzi?
Mirizzi is an Argentine Surgeon
He carried out the first operative cholangiogram in 1931, also known as the “mirizzigraphia”
Pablo Luis Mirizzi (25- 01-1893 to 28-08-1964)

Is there a classification for the disease?
Yes, many Acute vs chronic Cystic duct variant vs no variant Obstruction due to stone vs obstruction
due to inflammationMorelli A, Narducci F, Ciccone R. Can Mirizzi syndrome beclassified into acute and chronic form? An endoscopic retrogradecholangiography (ERC) study.

How is it classified? McSherry and Csendes classifications
are most commonly used
McSherry Classification
Mirizzi syndrome classified into two types based on the ERCP features Type I: CHD compression without fistula Type II: presence of
cholecystocholedochal fistula
McSherry CK, Ferstenberg H, Virship M. The Mirizzi syndrome:suggested classification and surgical therapy. Surg. Gastroenterol.1982; 1: 219–25.
Csendes Classification Mirizzi syndrome classified into four types
type I: extrinsic compression of common duct due to an impacted stone at gallbladder neck or cystic duct
Type II: cholecystobiliary (either cholecystohepatic or cholecystocholedochal) fistula with the defect less than 1/3 of the duct circumference
Type III: fistula formation, wall defect up to 2/3 Type IV: fistula formation, complete destruction
of the duct wall

How to diagnose
Diagnosis of Mirizzi syndrome is difficult
biochemical profile not specific elevated bilirubin Elevated white cell count Deranged liver function
Further investigations are needed
Imaging
USG As an baseline for jaundice patient Should see
A large gallstone contracted or indiscernible gallbladder Dilated upper CBD +/- IHDs
These findings are not specific for Mirizzi syndrome
Imagings (2)… CT scan
Should be performed to rule out malignant causes of biliary obstruction
Distinguish features include A large gallstone Contracted GB Dilated CHD and IHD Soft tissue mass at upper
CBD, reported as Ca GB/cholangioCa usually
ERCP
Remains the most important investigation
serves both diagnostic and therapeutic purposes..
Diagnostic purposes Radiological assessment
Typical features: Curvilinear extrinsic
compression of CHD from lateral
Dilated CHD and IHD “relatively” normal
CBD Return of pus after
CBD cannulation Microbiological
assessment Bile x c/st
Cytological assessment Brush cytology
Therapeutic purpose
Insertion of biliary stent to relieve biliary obstruction
Bring down bilirubin before operation Remove the stone with special
instruments
Despite of these… Pre-operative diagnostic rate remains low The quoted rate in the literatures were 8-
62.5% actually not very important not recognizing
it before OT but it is disastrous if not recognized intra-op
Fail to recognize this condition may lead to significant morbidity and mortality

Management options Surgical
Open surgery Laparoscopic surgery
Non-surgical Endoscopic Interventional radiology
Percutaneous transhepatic stone removal Extracorporeal shock-wave lithotripsy Oral dissolution therapy
Open surgery Remains the gold standard of treatment
with good short term and long term result.

How do we do it? Kocher’s incision Frozen section should be sent if malignancy is suspected Mobilize the gallbladder using the fundus first approach Transect gallbladder at around Hartmann’s pouch region
(partial cholecystectomy) Remove the stone, if there is a gush of bile, this suggest
presence of cholecystobiliary fistula Then you have to decide whether to..
Repair or reconstruct according to extent of destruction
ECBD or not depends on suspicion of residual stone in common duct
T-tube or not depends on likelihood of biliary stricture and bile leaks from repair site
Methods of reconstruction
Controversies in management
Treatment approach Which repair method is the best? Direct
repair or HJ for all the case
Placement of t-tube When and where to insert t-tube? Proximal, distal or right into the fistula?
No randomized control trial to answer these questions
Laparoscopic surgery
Technically feasible but more risky Most series involved small case
number and the successful cases were limited to mild disease (type I or II)
Higher complication rate, re-operation rate and conversion rate (near 100% conversion for type II disease)

Endoscopic treatment Method
Use of mother-and-baby scope
Fragment the stone with EHL
Extract the stone with basket
Drawbacks Stone not easily
accessible, especially for type I
May need multiple sessions and time consuming
Reserve for poor surgical candidate

Other treatment options
Percutaneous transhepatic stone removal Reserved for patient with high operative
risk
Oral dissolution therapy May not work for large stone and
obstructed cystic duct Cholesterol stones are not as common as
compared to the western patients
To conclude
Mirizzi syndrome is uncommon but important
ERCP and CT are the two important investigations
treatment should be individualized open surgery with adequate
treatment often provide satisfactory outcome
Thank you
0.3% to 3%, why so variable?
depends on accessibility of medical services, i.e. USG, lap chole…
