Pathologies colangiopancreatography.

 

1. Methods of Colangiopancreatography:

• Endoscopic Retrograde Cholangiopancreatography (ERCP):

  • Description: An endoscopic procedure where a contrast dye is injected into the bile and pancreatic ducts through a catheter inserted via the duodenum.
  • Uses: Diagnosis and treatment of bile duct stones, strictures, infections (e.g., cholangitis), and pancreatic duct abnormalities.

• Magnetic Resonance Cholangiopancreatography (MRCP):

• Description: A non-invasive imaging technique using magnetic resonance imaging (MRI) to obtain detailed images of the bile and pancreatic ducts.
• Uses: Visualization of ductal anatomy, detection of stones, and assessment of ductal strictures or tumors.

2. Common Pathologies Diagnosed by Colangiopancreatography:

• Biliary Tract Stones (Choledocholithiasis):

  • Description: Presence of stones in the bile ducts.

• Cholangiocarcinoma:

  • Description: Malignant tumor of the bile duct.

• Pancreatic Duct Obstruction:

  • Description: Blockage of the pancreatic duct, which can be caused by stones, tumors, or strictures.

• Acute Cholangitis:

  • Description: Infection of the bile duct system, often due to obstruction.

• Primary Sclerosing Cholangitis (PSC):

  • Description: Chronic liver disease characterized by inflammation and scarring of the bile ducts.

• Pancreatic Cancer:

  • Description: Malignancy of the pancreas that can invade or obstruct the pancreatic duct.

• Cystic Lesions of the Pancreas:

• Description: Fluid-filled sacs within the pancreas, such as pseudocysts or cystadenomas.
