Imaging techniques

Ultrasound this is most useful

  • Most important to show intrahepatic bile ducts dilatation
  • Measure the diameter of CBD (normal up to 7 mm)
  • Comment on the status of the GB and its stones
  • Visualize CBD diameter, stones or areas of narrowing
  • Tumors in the region of the pancreas is seen

CT (conventional or helical) competes with the U/S especially as regards the pancreatic tumors.

cholangiogram
cholangiogram
  • Preoperative cholangiogram
    • IV cholangiogram
    • PTC
    • ERCP
  • Intra operative
  • T tube ( post operative )

Investigations for a case of obstructive jaundice

ERCP

  • ERCP is an outpatient procedure that combines endoscopic and radiologic modalities to visualize both the biliary and pancreatic duct systems.
    • Endoscopically, the ampulla of Vater is identified and cannulated.
    • A contrast agent is injected into these ducts, and
    • x-ray images are taken to evaluate their caliber, length, and course.
  • ERCP is used to
    • get a final diagnosis and
    • do biopsy of ampullary tumors, or brush cytology.
investigations for a case of obstructive jaundice19
Investigations for a case of obstructive jaundice

ERCP

  • It can be also therapeutic for
    • stone extraction by Dormia basket or
    • insertion of a stent, both are preceded by sphincterotomy.
  • It has its risks
    • ascending infections,
    • perforations,
    • pancreatitis, an
    • bleeding due to sphincterotomy done routinely before CBD cannulation
congenital caroli s syndrome
Congenitalcaroli’s syndrome

investigations for a case of obstructive jaundice31
Investigations for a case of obstructive jaundice

MRCP

  • a sensitive noninvasive method of detecting biliary and pancreatic duct stones, strictures, or dilatations within the biliary system.
  • It is also sensitive for helping detect cancer.

Investigations for a case of obstructive jaundice

MRCP (contraindications)

Absolute include

  • the presence of a cardiac pacemaker,
  • cerebral aneurysm clips,
  • ocular or cochlear implants
  • ocular foreign bodies.

Relative contraindications include

  • the presence of cardiac prosthetic valves,
  • neurostimulators,
  • metal prostheses,
  • penile implants
investigations for a case of obstructive jaundice33
Investigations for a case of obstructive jaundice

PTC

  • performed by a radiologist using fluoroscopic guidance.
  • The liver is punctured to enter the peripheral intrahepatic bile duct system.
  • An iodine-based contrast medium is injected into the biliary system and flows through the ducts.
  • Obstruction can be identified on the fluoroscopic monitor.
investigations for a case of obstructive jaundice34
Investigations for a case of obstructive jaundice

PTC

  • It is especially useful for lesions proximal to the common hepatic duct.
  • Still, ERCP is generally preferred.
  • PTC is reserved for use if ERCP fails or when altered anatomy precludes accessing the ampulla.

PTC

Complications of this procedure include

  • the possibility of allergic reaction to the contrast medium.
  • peritonitis.
  • intraperitoneal hemorrhage, sepsis
  • cholangitis.
  • subphrenic abscess.
  • lung collapse.
  • Severe complications occur in 3% of cases
investigations for a case of obstructive jaundice41
Investigations for a case of obstructive jaundice
  • Endoscopic ultrasound (EUS) combines endoscopy and US to provide remarkably detailed images of the pancreas and biliary tree.
  • It uses higher-frequency ultrasonic waves compared to traditional US (3.5 MHz vs 20 MHz)
  • allows diagnostic tissue sampling via EUS-guided fine-needle aspiration (EUS-FNA).

clinical picture50
Clinical picture
  • The attack of biliary colic is the start with visceral type of pain (diffuse, colicky, radiating, and associated with vomiting)
  • Later on after 6 to 8 hours, the pain localizes to the right hypochondrium, and become associated with tenderness, rebound T, and rigidity and mild fever (somatic pain)
  • The presence of distended gall bladder is the hallmark of the disease, either discovered clinically or by U/S
  • In 25% of cases the bilirubin rises, due to compression of the CBD (Mirrizi syndrome) or less commonly due to an associated stone CBD
  • Serum amylase should be a routine as well as plain X ray abdomen (pancreatitis, and perforation or gas in biliary system
acute calculous cholecystitis
Acute calculous cholecystitis
  • Obstruction of GB outlet leads to chemical inflammation, which persists for 72 h then a fate of the following, will occur
    • Resolution (most common), with relief of obstruction ~>scarring and non-function of GB
    • Resolution of the inflammatory process with persistence of the obstruction (mucocele of the GB)

treatment
Treatment :
  • Cholecystectomy either conventional or laparoscopic is the ideal treatment for symptomatic patients.

  • Pain is colicky in nature, and typical for biliary colic
  • G.B not palpable except very rarely if its neck is obstructed too (double stone)
malignant obstruction

  • Pain is constant and referred to the back in pancreatic tumor, while it is absent in CBD tumors
  • G.B is palpable except in Klatskin tumors
complications of obstructive jaundice
Complications of obstructive jaundice
  • Ascending cholangitis
    • Charcot's triad is classical clinical picture which is formed of intermittent pain, jaundice and fever
    • Cholangitis can lead to hepatic abscesses
    • Need parenteral antibiotics and biliary decompression
    • Operative mortality in elderly of up to 20%
complications of obstructive jaundice131
Complications of obstructive jaundice
  • Clotting disorders
    • Vitamin K required for gamma-carboxylation of Factors II, VII, IX, XI
    • Vitamin K is fat-soluble. No absorbed. So it needs to be given parenterally
    • Urgent correction will need Fresh Frozen Plasma
    • Also endotoxin activation of complement system
complications of obstructive jaundice132
Complications of obstructive jaundice
  • Hepato-renal syndrome
    • Poorly understood
    • Renal failure post intervention
    • Most probably due to gram negative endotoxinaemia from gut
    • Preoperative lactulose may improve outcome by improving altered systemic and renal haemodynamics
  • Drug Metabolism
    • Half-life of some drugs prolonged. (E.g. morphine)
    • Impaired wound healing.

Treatment for cholangiocarcinoma of CBD

Palliative

  • Bypass surgery
    • Round ligament approach for Klatiskin tumors (on condition that the carina is permitting right to left communication)
    • Hepatico jujenostomy for middle and low tumors
    • Cholecystojujenostomy for low tumors.
    • usually we add gastrojujenostomy and enteroanastomosis (triple anastomosis) for pancreatic head tumors

Treatment for cholangiocarcinoma of CBD

For operable cancers

  • For Klastiskin tumor,
    • segment IV excision provides good access to the confluence
    • allows good proximal clearance and facilitates hepaticojujenostomy
  • For middle tumors excision of the tumor from just below the carina to the duodenum is done with hepaticojujenostomy
  • For distal tumors. Whipple operation is done
biliary stricture etiology
Biliary strictureEtiology
  • Congenital (biliary atresia)
  • Traumatic (most important, and usually follow cholecystectomy)
    • Complete ligation of CBD
    • Narrowing of the duct by partial inclusion in a ligature
    • Ischemia of the duct, or diathermy injury
  • Inflammatory Sclerosing cholangitis (multiple strictures separated by normal or dilated segments).
  • Cholangiocarcinoma
sclerosing cholangitis
Sclerosing cholangitis
  • PSC (primary sclerosing choangitis ) is a chronic cholestatic biliary disease characterized by non suppurative inflammation and fibrosis of the biliary ductal system.
  • The cause is unknown but is associated with autoimmune inflammatory diseases such as chronic ulcerative colitis.
sclerosing cholangitis146
Sclerosing cholangitis
  • Most patients present with fatigue and pruritus and, occasionally, jaundice.
  • The natural history is variable but involves progressive destruction of the bile ducts, leading to cirrhosis and liver failure.
biliary stricture
Biliary stricture
  • Investigations used are similar to those used in any case of obstructive jaundice (U/S then CT, ERCP, MRCP or PTC
  • Treatment is centered on creating a biliary enteric anastomosis with mucosa-to-mucosa sutures without compromising the blood supply of any of the ends.
