Surgical causes of neonatal jaundiceSurgical causes of neonatal jaundice


Neonatal jaundice

Usu accumulation of unconjugated bilirubinConjugated through glucuronyl transferaseConjugated water soluble then excreted into the biliary system Gi tract. biliary system Gi tract. Newborns

high Hgb, Rh, ABO and rare blood group abnormalities leading to hemolysisto hemolysisimmature conjugating systeminfections

S h t i t l ti f bili bi i th ti So can have transient accumulation of bilirubin in the tissues – physiologic jaundice of the neonatal periodEvident day 5-7 Usually goes away by week 2


Persistent neonatal jaundicej

Biliary atresia (60%)Biliary atresia (60%)Neonatal Hepatitis (35%)

hepatic inflammation that can be secondary to several p ydifferent causes

Choledochal cyst (5%)Al ill d t i h ti d l i Alagille syndrome – arteriohepatic dysplasia –congenital syndrome associated with abnormal facies.

Spontaneous perforation of extrahepatic bile ductsp p pAscites, mild jaundice, failure to thriveUsu occurs at the junction between the cystic and common bile ducts

Inspissated bile syndrome – bile plug syndromeE h i b i f h bil d b biliExtrrahepatic obstruction of the bile ducts by biliarysludgeAssociated with massive hemolysis, hemorrhage, TPN, y , g , N,cystic fibrosis and other intestinal diseases such as Hirchsprungs


Choledochal cysty

Congenital biliary tract disorderCongenital biliary tract disorder1: 2 million – 1: 13,000Idiopathic dilation of the common bile ductIdiopathic dilation of the common bile duct


Etiology:

Can be associated with an anomalous jcn of the jpancreatic and common bile ductsPossibly an abnormal pancreatic and biliary duct j i i h h f i f h l b junction with the formation of a common channel by which the pancreatic enzymes are secreted. Reflux of pancreatic enzymes into the bile duct Reflux of pancreatic enzymes into the bile duct

This weakens the bile duct wall by enzymatic wall destruction dilation inflammation cyst formation Infectious agentsBiliary autonomic dysfunction

Bile flow into the intestinesRoux en y limb of the jejunumLiver biopsy to evaluate the degree of fibrosisSurgical success is increased if its done before 8 weeks

Intussucepted antireflux valve using appendix and jejunal limb –minimize postoperative cholangitis

Outcome

Usu successful if done before 2 months Two thirds of the require liver transplant secondary to progressive liver failure

1/3 of pts remain asymptomatic 1/3 never have bile flow and require early transplant/1/3 initially have good bile flow but subsequently
