Liver Flashcards
Ductus venous connects
Portal vein and inferior vena cava
Aka hilum of liver
Porta hepatis
The hepatoduodenal ligament contains?
Portal triad
Occlusion of hepatoduodenal ligament (technique)
Pringle maneuver
Only clotting factor not found in the liver
Factor VIII
Caudate lobe is drained by te
IVC
Assessment of hepatic reserve
Child Turcotte Pugh Score
Parameters in child pugh score
Nutrional status, ascites, enceph, bilirubin, albumin, PT
Normal portal pressure
5-10 mmHg
pressure necessary for varices to form and bleed
> 12
Medical prevention of varices
Beta blockers
Preferred agent for pharmacologic therapy of varices
Octreotide
When is TIPS ised
Esophageal varices- child B and C (A- surgical shunt)
Congestive hepatopathy characterized by obstruction to hepatic venous flow
Budd chiari syndrome
Aka ecks fistula
End to side portacaval anastamosis
Aka warren shunt
Distal splenorenal shunt
Dx and TX for budd chiari
Hepatic venography; systemic anti coagulation
Most common symptom and indication for resection
Hemangioma
Mgmt for hemangioma
Enucleation or resection
Clearest risk factors for adenoma
Oral contraceptive use
Mgmt for adenoma
Resectiont
Mgmt for nodular hyperplasia mgmt
Symptomatic:resect; asynp: observe
Most common malignant liver tumor
Metastatic
Aka klatskin tumor
Extrahepatic proximal(hilar) cholangiocarcinoma
Mgmt for cholangiocarcinoma
Resection- gold standard’
Roux en y hepaticojejunostomy is usually for
Cholangiocarcinoma
Cystic artery is a branch of
Right hepatic artery
Gallbladder lacks what layers
Mucosa and submucosa
direct communication between liver and GB
Duct of Luschka
Stone size that may carry a risk for GB CA
> 3cm
Brown pigment stones are usually due to
Cholangitis
Most common choledochal cyst
Fusiform
Abdominal pain, jaundice, mass
Choledochal culust
Caroli’s disease
Type 5 choledochal cyst
Management for sclerosing cholangtis
Liver transplant
Size of gallbladder polyp with malignant potential
> 1cm
Most common gallbladder carcinoma
Adenocarcinoma
Klatskin tumor
Perihilar cholangiocarxcinoma
Most important factor determining resectability of bile duct carcinoma
Proximal extent (klatskin tumor)
Main pancreatic duct
Witsung
Accessory duct
Santorini
Most common congenital anomaly of the pancreas
Pancreas divisum
Tx for pancreas divisun
Sphincterotomy(enlarge duct of santorini)
Tx for annular pancreas
Duodenoduoenostomy - bypass(proximal small intestinal obstruction)
Most important and largest blood supply of pancreas
Splenic artery
Most common cause of death of acute pancreatitis
Sepsis
Cut off sign and reverse 3 or inverted 3 sign
Acute pancreatitis
Diagnostic gold standard for acute pancreatitis
Abdominal Ct scan
50% mortality with ranson score of
> 7
Puestow Gillesby procedure
Chronic pancreatitis (roun en y pancreaticojejunostomy)
Generally a helpful imaging technique for the pancreas
CT scan
Resectability of liver
Liver end playe
Pancreas is inresectable if what is involved
SMA
Rule of 6
Pseudocyst of pancreas: >6cm >6 weeks: drain!
Pancreatic tumors etiology
Smoking
Most common pancreatic tumor
Adenocarcinoma
Only definitive and potentially curative tx of periampullary carcinoma
Whipple’a surgery
Whippled triad
Symptomatic fastinf hypoglycemia, serum glucose <50, relief of symptoms with glucose administration
Mgmt for insulinoma
Simple enucleation
Tx for VIPoma
Debulking as palliative tx
Mgmt for glucagonoma
Debulking
Whipples triad is performed on insulinoma only if
It is close to the main pancreatic duct
The quadrate and caudate lobes are functionally part of wc side of the liver
