Jaundice

Definition

Accumulation of yellow pigment in the

skin and other tissues (Bilirubin)

Jaundice definitionJaundice definition

�� It arises from the abnormal accumulation It arises from the abnormal accumulation of of bilirubinbilirubin in body tissues, which occurs in body tissues, which occurs when the serum when the serum bilirubinbilirubin level exceeds level exceeds 3 mg/3 mg/dLdL or 50 or 50 uumol/L.mol/L. 11 Excess Excess bilirubinbilirubincauses a yellow tinting to the skin, sclera, causes a yellow tinting to the skin, sclera, and mucous membranes. and mucous membranes.

� The presence of jaundice can indicate a The presence of jaundice can indicate a transient hepatitis, transient hepatitis, biliarybiliary obstruction, or obstruction, or progressive deterioration in a patient progressive deterioration in a patient awaiting liver transplantation. Thus, the awaiting liver transplantation. Thus, the appropriate management of the patient with appropriate management of the patient with jaundice depends on localizing the site and jaundice depends on localizing the site and nature of the problem. nature of the problem.

Evaluation to the patient with jaundiceEvaluation to the patient with jaundice

�� The investigation of a patient with jaundice The investigation of a patient with jaundice begins with a thorough review of the history begins with a thorough review of the history of presentation, medication use, past of presentation, medication use, past medical history, physical examination, and medical history, physical examination, and evaluation of liver function tests. evaluation of liver function tests.


� Several questions must be answered initially: � 1. Is the elevated bilirubin conjugated or unconjugated? In

general, most jaundiced patients will not have an isolated unconjugated hyperbilirubinemia.

� 2. If the hyperbilirubinemia is unconjugated, is it caused by increased production, decreased uptake, or impaired conjugation?

� 3. If the hyperbilirubinemia is conjugated, is the problem intrahepatic or extrahepatic?

� 4. Is the process acute or chronic?

generally not helpful. � The presence of a friction rub or bruit suggests

malignancy.

PTCPTC

� PTC visualizes the biliary tree in 90% to 100% of patients with dilated ducts and localizes the site of obstruction in 90% of cases. It locates the obstruction in 50% to 90% of patients without dilated ducts, as determined by ultrasound. PTC is less expensive than ERCP and often is easier to perform. The patient must have a prothrombintime of less than 16 seconds,a platelet count greater than 50,000, and no ascites. Minor complications occur in 30% of patients. Major complications, including sepsis, bleeding, biliary leak, pneumothorax, arteriovenousfistula, hematoma, abscess, and peritonitis, occur in 1% to 10% of patients who undergo PTC.
