2. Jaundice
⢠Itâs a French word meaning Yellow.
⢠Jaundice is a term used for yellow pigmentation of sclera skin or
mucus membrane due to deposition of Bilirubin.
⢠Normal Bilirubin is 0.2-1.0mg/dL.
⢠Jaundice clinically detected in sclera when S.Billirubin is >2.5mg/dl.
⢠Jaundice is clinically detected in Skin/Mucus Membrane when S.
Billirubin is >6.0mg/dl.
3. Billirubin Metabolism
⢠Bile contains
1. Bile salt.
2. Lecithin
3. Cholesterol
4. Bile Pigment
⢠Biles Salt are
1. Primary(Cholate & Chenodeoxycholate)
2. Secondary(Deoxycholate & Lithocholate)
4. Entero hepatic Circulation
Bile salt in Bile
Jejunum & Ileum it
help in fat Digestion
Reabsorption in
terminal Ileum
Portal Vein Blood
Liver
⢠Entire Bile Salt Pool of 2.5-4.0gm
circulates twice through the
enterohepatic circulation during
each Meal.

7. Causes of Obstructive Jaundice
⢠Most Common is
1. Common Bile Duct Stone
2. Periampullary Carcinoma( Ca
Head Pancreas most Common)
Periampullary Malignancy
includes Malignancy of Head
Pancreas Ampulla of Vater
Malignancy Lower End CBD
Malignancy & Duodenal
Malignancy
8. Causes
⢠Hepatic Duct
1. Cholangiocarcinoma e.g KLATSKIN TUMOR( TUMOR involving
Hepatic Duct Bifurcation).
2. Extrinsic Pressure by Portal Lymphnodes due to Metastasis or
Lymphoma.
9. ⢠Common Bile Duct
1. Common Bile Duct Stone.
2. Common Bile Duct Stricture.
3. Gall Bladder Carcinoma.(Extrinsic Compression)
4. Choledochal Cyst
5. Obstruction by Ascaris Lumbricoides & Clonorchis Sinensis.
6. Mirriziâs Syndrome Stone in Cystic Duct or Hartmannâs Pouch
causing pressure obstruction of Common Bile Duct.
10. ⢠Pancreas
⢠Periampullary Carcinoma
1. Carcinoma of Head of Pancreas.
2. Pseudocyst of Pancreas.(Extrinsic Compression)
11. PATHOPHYSIOLOGY OF OBSTRUCTIVE JAUNDICE
Obstructive jaundice is a condition in which there is blockage of the flow of
bile out of the liver. This results in an overflow of bile and its by-products
into the blood, and bile excretion from the body is incomplete.
Hepatic functions
Protein synthesis,
Reticulo-endothelial function
Hepatic metabolism
Coagulation defect..increased prothrombin time(Decreased absroption of fat solube vitamins A,D,E,K(decreased factor XI ,XII
,platelets)
Renal functions
Renal vasoconstriction
Activation of complement system causing peritubular and glomerular fibrin deposition leading to
tubular and cortical necrosis
Cardiovascular effects
Decreased peripheral vascular resistance
Bradycardia due to direct effect of bile salts on SA node
Decreased cardiac contractability
Delayed wound healing due to defective synthesis of collagen
13. CLINICAL FEATURES
⢠Icterus: Usually dark yellow may have a greenish tinge if bilirubin is
reduced to billiverdin.
⢠Jaundice
1. Fluctuant in case of CBD Stones & Ampullary Growth.
2. Progressive in case of malignant obstruction by Carcinoma of Head
of Pancrease
⢠Hepatomegaly
15. COURVOISIERâS LAW
⢠PALPABLE GALL BLADDER
ď A nontender palpable gall bladder in a patient of jaundice is normally not due to
stone obstructing the bile duct whereas other causes are common by comparison.
ď Explanation of Courvoisier's Law:: If in a jaundice patient GB is enlarged it is not
a case of stone impacted in the CBD as previous inflammation leads to Gall Bladder
Fibrotic and non distensible.
ď Causes are Carcinoma of Head of Pancreas & Periampullary Carcinoma.
ď Exceptions of Curvoisierâs Law
1. Double Impaction of Stone( CBD & Cystic Duct)
2. Stone at Ampulla Of Vater
3. Oriental Cholangiohepatitits
4. Mirriziâs Syndrome
16.
17. Bio Chemical Test 1
⢠S Billirubin: In Surgical Jaundice there will be(Direct)
hyperbilirubinemia.
⢠Normal 0.2 -1.0mg/dl
⢠Usually in CBD Stones S Bil(Total) is <10mg/dl.
⢠Usually in Neoplastic Obstruction S Bil(Total) is >10mg/dl.
⢠Total Billirubin rise upto a plateau level of 25-30mgdl at this lever
patient has loss in urine=daily Production.
⢠Liver Function Test Interpretation is (Total B/Direct B/AST/ALT/Alk
Pho)
18. Bio Chemical Test 2
⢠SGOT/SGPT(AST/ALT) : Normal level is 5-35IU/L
⢠Modest rise in Surgical Jaundice.
⢠AST if more than 1000IU/L s/o Medical Jaundice due to Hepatitis.
⢠ALT (SGPT) more specific for Liver Injury due to any cause.
19. Biochemical Test 3
⢠Serum Alkaline Phosphatase
⢠Normal level 3-13 KA Units/L or 60-300 IU/L.
⢠S ALK Phosphatase is usually raised in obstructive jaundice but not so
in hepatocellular Jaundice.
⢠If the level is more than >30 KA Units S/O Significant Obstructive
Jaundice.
⢠Increased value are because of increase production so it may be
elevated before the S Billirubin value raises.
⢠Serum Alk Phosphatase also increased in disease of intestine and
bone.
20. Bio Chemical Test 4
⢠Serum 5â Nucleotidase.
⢠Leucine Aminopeptidase
⢠Gamma Glautamyl Transpeptidase
ď All of the above enzymes are more specific for Biliary Obstruction.
21. Bio Chemical Test 5
⢠Serum Albumin : Noraml level is 3.0 to 5.5 gm/Dl
⢠Usually normal in Obstructive Jaundice but low value suggest
parenchymal dysfunction as in hepatocellular Jaundice.
⢠It may decrease when liver is affected by metastatic Nodules.
22. Bio Chemical Test 6
⢠Prothrombin Time
⢠It is usually expressed as INR
⢠Normal: Control is 15 Seconds & Normal INR is <1.5
⢠PT is elevated because of decrease in synthesis of VIT K depedent
clotting factors( which is a fat soluble vitamins which is not absorbed
in obstructive jaundice)
23. Bio Chemical Test 7
⢠Urine Examination :
Frothâs Test to detect Conjugated Billirubin.
Hayâs Test to detect presence of Bile Salt in Urine.
Fouchetâs Test to detect Bile Pigment in Urine.
ABSENT UROBILLINOGEN IN URINE
⢠Stool:: Clay Color
⢠Stool for Occult blood in case of Ampullary Malignancy
24. Radiological Investigation: USG
⢠Findings will be
1. Presence of Dilated IHBR is s/o of Obstructive Jaundice.
2. CBD Diameter (Normal is 7-8 mm) if it is more than 8 mm
suggestive of dilatation.
3. Gall Stone and CBD Stone Can be identified.
4. Mass in CBD can be detected if it is >2 cm.
5. Pancreatic Head Malignancy detected if >2 cm.
6. Presence of Liver Metastasis and Ascites.
26. Radiological Investigation CECT Abdomen
⢠Higher Sensitivity and Specificity than USG for detection of bile
duct/pancreatic masses of 1-2 cm diameter.
⢠It is useful in determining resectability of cancer of Bile Duct or
Pancreatic Head Masses.
⢠It visualise the course of Bile Duct better than USG and hence more
likely demonstrated the level & Cause of Ductal Obstruction.
⢠Although USG better (more Sensitive )than CT Scan for detecting GB
Stone CECT is better(More Sensitive) for documenting CBD Stone.
31. Clinical Classification of Obstructive Jaundice
⢠Type I Complete
Obstruction(Classical Symptoms
with Biochemical Changes)
1. Malignancy of Head of Pancreas.

Obstruction(Symptoms with
Biochemical Changes But Jaundice
may or may not be Present).
ď1. Choledocholithiasis
ďPeriampullary tumor
ďDuodenal diverticula
ďCholedochal Cyst
ďPapillomas of the bile duct
ďIntra biliary parasites
ďHemobilia
32. Clinical Classification
⢠Type III Chronic Intermittent
Obstruction(With or without classical
symptoms but pathological changes
are present in bile duct and liver )
ď1. Strictures of the CBD
Congenital
Traumatic
Sclerosing cholangitis
Post radiotherapy
ďStenosed biliary enteric anastomosis
ďCystic fibrosis
ďChronic pancreatitis
ďStenosis of the Sphincter of Oddi
⢠Type IV Segmental Obstruction( One
or more segment of IHB Radical)
1. Traumatic
2. Slerosing Cholangitis
3. IntraHepatic Abscess
4. Cholangiocarcinoma
33. Endoscopic Retrograde
Cholangiopancreatography(ERCP)
⢠It is combined Endoscopic & Radiological Approach.
⢠IND:: When USG s/o dilated IHBR with dilated CBD i.e Obstruction is
suspected to be at the lower biliary tract or near
pancreatic head.
37. Biliary stricture due to
cholangiocarcinoma
Bile duct obstruction
from chronic pancreatitis
38. ERCP
⢠Advantages::
⢠Endoscopic Visualization of
duodenum to rule out duodenal
obstruction.
⢠Endoscopic Sphincterotomy with
dormia basket removal of CBD
Stone.
⢠Biopsy & Cytology.

for non surgical palliation.
⢠It is contraindicated in Recurrant
Acute Pancreatitis & Unfavourable
anatomy.
⢠Complication
1. Pancreatitis
2. Cholangitis
3. Hemorrhage
4. Sepsis
39. Radiological Investigation ENDO USG
⢠It is more accurate than
combined ERCP & CT Scan in
defining the nature & extent of
the cause of Biliary Obstruction.
⢠It is also quite sensitive in
determining the resectability in
periampullary malignancy.
⢠EUS 98% Sensitivr in diagnosis of
etiology of Obstructive Jaundice.
⢠It allows us to take tissue
sampling by EUS guided FNAC.
40. EUS
⢠The sensitivity of EUS for the identification of focal mass
lesions in pancreas has been reported to be superior to that
of CT scanning, both traditional and spiral, particularly for
tumors smaller than 3 cm in diameter.
⢠Compared to MRCP for the diagnosis of biliary stricture, EUS
has been reported to be more specific (100% vs 76%).
42. Percutaneous Transhepatic Cholangiography
⢠For Visualization of Biliary Tract by
instillation of contrast material
directly into a bile duct.
⢠IND: PTC indicated when USG
shows dilated IHBR but the CBD is
not dilated i.e Obstruction is
suspected in the upper Biliary
Tract.
⢠CI: Coagulopathy & Ascites
⢠Complication: Bleeding Bile Leak
Hemobilia
Cholangitis
43. PTC & ERCP
⢠PTC & ERCP are not contradictory to each other they are
supplementary investigation to each other.
44. MRCP(Magnetic Resonance
CholangioPancreatography)
⢠MRCP is based on principle of
visualization of ducts containing
bile on T2 Weighted Images.
⢠Advnatages:
1. Non Invasive
