Galbadder disease _ نوري حنون Flashcards
The gall bladder Anatomy
Pear shape (7.5 – 12 cm in length )
Capacity > 50 ml
gall bladder consist of
Fundus , body , neck & infundibulum
duct are …
-cystic duct ( 2.5 cm , 0,5 cm )
join common hepatic duct ( 2.5 cm )
to form CBD 7.5 cm
Blood supply of the gallbadder …
cystic artery from Rt. Hepatic artery
what the congental anomalies of the galbadder artery ?
Caterpillar turn
means Tortuous Rt. Hepatic artery in front of origin of cystic duct with short cystic Ar.
Lymphatics …
two ways ;
1- To cystic L.node of lund →coeliac L. N.
2- Directly to liver
Bile consist of …
97% water
→2% bile salt
→1% bile acid and cholesterol.
Bile production from the liver
40 ml / hour = 1000 ml /day .
Gall bladder function
1- Reservoir & storage.
2- Concentration of bile 5-10 times .
3- secretion of mucin ; 20 ml / day .
Investigations of biliary tract by …
-Plain Xray : Radio opaque stone 10 – 20 %. Porcelain gall bladder . Limey bile . Gas in biliary tree.
2) Oral cholecystography & iv. Cholangiography.
Out of use .
Historical interest.
(both x ray and chlecystography both not used )
*3) Ultrasonography :
Prime test .
Standard test .
Quick , non-invassive test .
4) *ERCP. & endoscopic ultrasonography .
5) *PTC .
Percutaneous transhepatic cholangiography(not used really)
6)* MRCP (standard, no contrast).
so the most important is the US MRCP ERCP and CT scan for tumor and LN
7) Radio isotope scanning
-99mTC
-labelled HIDA (hepatobiliary iminodiacetic acid (HIDA)) ,
-IODIDA .
Iv. given , excreted in bile, gall bladder visualised
30 minute if delayed to 1 hour suggest acute cholangitis or contracted gall bladder ( chronic ) .
8) CT. Scan :
To detect liver and pancreatic lesion .
Cancer extent and staging .
L. Node enlargement .
9) Per operative cholangiography .كلللش رفيع
10) Per operative choledochoscopy :
Flexible fibreoptic endoscope to localize and extract stone
what’s the Radio isotope scanning ?
-99mTC
-labelled HIDA (hepatobiliary iminodiacetic acid (HIDA)) ,
-IODIDA .
Iv. given , excreted in bile, gall bladder visualised
30 minute if delayed to 1 hour suggest acute cholangitis or contracted gall bladder ( chronic ) .
CT. Scan benefet in the gallblader?
To detect liver and pancreatic lesion .
Cancer extent and staging .
L. Node enlargement .
Ultrasonography benefet in the gallblader?
it’s the standard test
Congenital abnormalities of GB ?
1- Abscence of G.B.
2- Phryngian cap 2 – 6 % , phrygian cap like hats of people of phrygia (asia Minor). Suptum in G. bladder either complete or incomplete .
يعني بدل ما تكون كيس واحد راح نشوفها كانما مقسومه الى نصفين
3- Intra hepatic G.B.
4- Floating G.B. → torsion .
5- Double G.B
Congenital abnormalities of the bile duct ?
Cystic duct anomalies : Intra hepatic ;
Accessory duct
They are small ducts that distinctly enter the gallbladder bed
Low insertion .
Low medial insertion of the cystic duct occurs when it joins the extrahepatic bile duct from the medial aspect at or near the ampulla of Vater
Short or absent.
Extra hepatic biliary Atresia means
Define as partial or total absence of bile duct between porta hepatis and the duodenum
Extra hepatic biliary Atresia incidence ..
1/ 14,000 live births
Extra hepatic biliary Atresia complication andout cme if not fixed
Occlusion will lead to inflamation of the duct → destruction of the duct → fibrosis → obliteration طمس
so as result of olibaration newborn will having :
- Jaundice
-Biliary cirrhosis
is a disease caused by damage to bile ducts in the liver. These small channels carry the digestive fluid, or bile, from the liver to the small intestine. … It can lead to permanent scarring and cirrhosis
- Portal hypertension .
- Liver failure
Extra hepatic biliary Atresia types
1 occlusion of common bile duct
2 occlusion of common bile duct and hepatic
3 occlusion of common bile duct, hepatic
and Rt and Lt heparic duct
Clinical features of Extra hepatic biliary Atresia
1- Jaundice at birth – progressive – 2- Pale muconium. 3- Dark urine . 4- Steatorrhoea leading to Osteomalacia( biliary rickets ). --------------------- 5- Clubbing of fingers . 6- Portal hypertension . 7- Another anomalies in 20% .
DDx of the Extra hepatic biliary Atresia?
1- Neonatal jaundice .
2-Neonatal hepatitis.
2- Choledochal cyst .
3- Inspissated bile syndrome .
