    Study Notes

    Hepatobiliary System

    • The liver is the largest organ in the body, located in the right upper quadrant of the abdomen, protected by the ribs and anchored by peritoneal ligaments.
    • Abdominal pressure helps hold the liver in place.
    • Liver functions include metabolism of substances from the portal circulation, synthesis of clotting factors and vitamins, and detoxification.
    • The liver receives blood from two sources: the hepatic artery (oxygenated blood) and the portal vein (venous blood from the abdominal viscera).

    Biliary Tree

    • The biliary tree comprises ducts that transport bile from the liver to the duodenum.
    • The right and left hepatic ducts merge to form the common hepatic duct.
    • The cystic duct from the gallbladder joins the common hepatic duct to form the common bile duct.
    • The common bile duct may join with the pancreatic duct before entering the duodenum at the hepatopancreatic ampulla (ampulla of Vater).
    • The sphincter of Oddi controls the flow of bile and pancreatic juice into the duodenum, and bile release is triggered by cholecystokinin in response to fatty foods.

    Gallbladder

    • The gallbladder is a pear-shaped sac located under the liver's right lobe.
    • It stores and concentrates bile produced by the liver, releasing it into the duodenum to aid fat digestion.

    Pancreas

    • The pancreas is an elongated organ behind the stomach, spanning the left abdomen.
    • Pancreatic exocrine functions include producing digestive enzymes (trypsin, amylase, lipase) for protein, starch, and lipid digestion, discharging them into the duodenum.
    • Pancreatic endocrine functions involve islets of Langerhans (α- and β-cells) that produce insulin and glucagon, regulating carbohydrate metabolism.

    Imaging Considerations

    • Radiography: Abdominal radiographs are helpful for identifying calcium deposits (calcifications) in the hepatobiliary system and detecting radiopaque gallstones. Visualization of gas in the gallbladder and common bile duct may indicate infection or complications like gallstone ileus or postoperative issues.
    • Dynamic Imaging: CT and MRI provide excellent contrast resolution and can be enhanced with Intravenous contrast media for the assessment of masses and conditions like cholecystitis.
    • Ultrasound (US): A preferred noninvasive method for evaluating the gallbladder and biliary tree; highly accurate in detecting gallstones and assessing liver conditions.
    • Percutaneous Transhepatic Cholangiography (PTC): Involves inserting a needle into the biliary tree to inject contrast medium to differentiate medical from surgical jaundice and detect obstructions or tumors.
    • Endoscopic Retrograde Cholangiopancreatography (ERCP): A gastroenterologist utilizes an endoscope to visualize the biliary system and pancreatic duct. It assesses obstructions, bleeding disorders, and pancreatic issues.
    • Operative Cholangiography: Performed during surgical procedures like cholecystectomy to detect biliary calculi.
    • T-Tube Cholangiography: Post-cholecystectomy procedure to confirm the common bile duct is clear or free of calculi.

    Inflammatory Diseases

    • Various inflammatory liver diseases exist, such as alcoholic induced liver disease.
    • Common types include fatty liver, alcoholic hepatitis, and cirrhosis.

    Nonalcoholic Fatty Liver Disease (NAFLD)

    • NAFLD is a liver condition characterized by fat accumulation in liver cells (hepatocytes).
    • The buildup of fat may not be a result of alcohol consumption but various other factors.
    • Early stages often exhibit no symptoms, making diagnosis challenging.
    • Weight loss and exercise can help address insulin resistance and metabolic issues.

    Cirrhosis

    • Cirrhosis is a chronic liver condition where healthy liver tissue is replaced by fibrous tissue.
    • Causes range from chronic alcohol abuse to diseases.
    • Symptoms include jaundice, portal hypertension, and complications like esophageal varices and ascites.

    Viral Hepatitis

    • Viral hepatitis is a common condition that interferes with the liver's ability to excrete bilirubin.
    • This condition is caused by various viruses, resulting in acute liver inflammation.
    • Different types of viral hepatitis exist (hepatitis A, B, C, D, E, G), each with varying modes of transmission and courses.

    Jaundice

    • Jaundice is a sign, not a disease, presenting as yellowish skin and eye discoloration due to bilirubin accumulation.
    • Causes of jaundice include hemolytic disease, liver damage, and biliary system obstruction.
    • Imaging methods like sonography help differentiate between obstructive and nonobstructive jaundice.
    • Common bile duct dilation typically indicates an obstruction.

    Neoplastic Diseases

    • Neoplastic diseases of the liver include hepatocellular adenoma, hepatocellular carcinoma, hemangiomas, and metastatic liver disease.
    • Diagnostic methods may involve sonography, CT, MRI, and liver biopsy.
    • Treatments can include surgical resection, chemotherapy, and liver transplantation, depending on the specific type and extent of the neoplasm.

    Carcinoma of the Gallbladder

    • Gallbladder carcinoma, frequently a malignant adenocarcinomas.
    • Symptoms generally include nonspecific abdominal complaints (pain, jaundice) and weight loss.
    • Diagnosis often involves CT scan and sonography.
    • Prognosis is usually poor due to early metastasis.

    Carcinoma of the Pancreas

    • Pancreatic carcinoma often presents late with nonspecific symptoms.
    • Risk factors include smoking, alcoholism, chronic pancreatitis, diabetes, and family history.
    • Diagnosis involves CT scans, sonography, MRI, and barium studies.
    • Treatment options involve radical surgery, radiation therapy, and chemotherapy.
    • Prognosis is generally poor with a limited 5-year survival rate.

    Key Takeaways of Neoplastic Diseases

    • Advanced imaging techniques like CT and MRI and sonography are crucial for diagnosis.
    • Treatment options are limited and outcomes in some cases, particularly for carcinoma types, often poor.
    • Early detection is essential, particularly for conditions like hepatocellular carcinoma and pancreatic cancer.
