682 Section III / Subspecialty Surgery

What is the differential diagnosis of increased creatinine?

What are the signs/ symptoms?

What is the workup for the following tests:

U/S with Doppler?

Radionuclide scan?

Biopsy?

What is the time course for return of normal renal function after transplant?

LIVER TRANSPLANT

(Remember: “-TION”) obstrucTION, dehydraTION, infecTION, intoxicaTION (CSA); plus lymphocele, ATN

Fever, malaise, HTN, ipsilateral leg edema, pain at transplant site, oliguria

Look for fluid collection around the kidney, hydronephrosis, flow in vessels

Look at flow and function

Distinguish between rejection and cyclosporine toxicity

LRD—3 to 5 days

Deceased donor—7 to 15 days

Who performed the first

Thomas Starzl (1963)

liver transplant?

 

 

What are the indications?

Liver failure from:

 

1.

Cirrhosis (leading indication in

 

 

adults)

 

2.

Budd-Chiari

 

3.

Biliary atresia (leading indication

 

 

in children)

 

4.

Neonatal hepatitis

 

5.

Chronic active hepatitis

 

6.

Fulminant hepatitis with drug

 

 

toxicity—acetaminophen

 

7.

Sclerosing cholangitis

 

8.

Caroli’s disease

 

9.

Subacute hepatic necrosis

 

10.

Congenital hepatic fibrosis

 

11.

Inborn errors of metabolism

 

12.

Fibrolamellar hepatocellular

 

 

carcinoma

What is the MELD score?

Chapter 73 / Transplant Surgery 683

Model for End Stage Liver Disease” is the formula currently used to assign points for prioritizing position on the waiting list for deceased donor liver transplant; based on INR, bilirubin, and creatinine with extra points given for the presence of liver cancer

What is the test for

ABO typing

compatibility?

 

What is the placement?

Orthotopic

What are the options for

1. Donor common bile to recipient

biliary drainage?

common bile duct end to end

 

2. Roux-en-Y choledochojejunostomy

What is the “piggyback

Recipient vena cava is left in place; the

technique”?

donor infrahepatic IVC is oversewn; the

 

donor superior IVC is anastomosed onto

 

a cuff made from the recipient hepatic

 

veins (allows for greater hemodynamic

 

stability of the recipient during OLT)

How does Living Donor

Adult donates a left lateral segment to a

Liver Transplantation

child or an adult donates a right lobe to

(LDLT) work?

another adult

What is a split liver

Deceased donor liver is harvested

transplant?

and divided into two “halves” for two

 

recipients

What is chronic liver

“Vanishing bile duct syndrome”

rejection called?

 

REJECTION

 

 

 

What are the red flags

Decreased bile drainage, increased

indicating rejection?

serum bilirubin, increased LFTs

What is the site of rejection?

Rejection involves the biliary epithelium

 

first, and later, the vascular endothelium

684 Section III / Subspecialty Surgery

What is the workup with the following tests:

U/S with Doppler?

Look at flow in portal vein, hepatic artery; rule out thrombosis, leaky anastomosis, infection (abscess)

Cholangiogram?

Look at bile ducts (easy to do; patients

 

usually have a T-tube if they have

 

primary biliary anastomosis)

Biopsy?

Especially important 3 to 6 weeks

 

postoperatively, when CMV is of

 

greatest concern

Does hepatorenal syndrome

Yes

renal function improve after

 

liver transplant?

 

SURVIVAL STATISTICS

 

 

 

What is the 1-year survival

80% to 85%

rate?

 

What percentage of patients

20%

requires retransplant?

 

Why?

Usually primary graft dysfunction,

 

rejection, infection, vascular thrombosis,

 

or recurrence of primary disease

PANCREAS TRANSPLANT

 

 

 

Who performed the first

Richard C. Lillehei and William D. Kelly

pancreas transplant?

(1966)

What are the indications?

Type I (juvenile) diabetes mellitus

 

associated with severe complications

 

(renal failure, blindness, neuropathy) or

 

very poor glucose control

What are the tests for compatibility?

ABO, DR matching (class II)

What is the placement? Heterotopic, in iliac fossa or paratopic

Why?

Measures the amount of amylase in

 

urine, gives an indication of pancreatic

function (i.e., high urine amylase indicates good pancreatic function)

What is the associated electrolyte complication?

Where is anastomosis of the exocrine duct in paratopic placement?

Why?

What is the advantage of paratopic placement?

What are the red flags indicating rejection?

Why should the kidney and pancreas be transplanted together?

Why is hyperglycemia not a good indicator for rejection surveillance?

Loss of bicarbonate

To the jejunum

It is close by and physiologic

Endocrine function drains to the portal vein directly to the liver, and pancreatic contents stay within the GI tract (no need to replace bicarbonate)

Hyperamylasemia, hyperglycemia, hypoamylasuria, graft tenderness

Kidney function is a better indicator of rejection; also better survival of graft is associated with kidney-pancreas transplant than pancreas alone

Hyperglycemia appears relatively late with pancreatic rejection
