Study Notes
Infections of the Liver
Ascariasis
- Caused by Ascaris lumbricoides.
- Ova can migrate from the gastrointestinal tract to bile ducts, leading to retrograde locomotion.
- Clinical symptoms include:
- CBD obstruction and intrahepatic stones
- Biliary colic
- Acute cholecystitis
- Acute pancreatitis
- Hepatic abscess
- Diagnosis via ultrasound and ERCP, which may reveal linear filling defects in bile ducts.
- Management options:
- Endoscopic extraction of worms
- Anti-parasitics such as Piperazine citrate, Mebendazole, or Albendazole.
- Surgical extraction if ERCP fails.
Schistosomiasis
- Hepatic schistosomiasis occurs via mesenteric venous system emboli.
- Clinical symptoms develop in three stages:
- Itching post cercariae entry
- Fever, urticaria, and eosinophilia
- Advanced symptoms (not specified).
- Diagnostic methods include fecalysis, serologic tests, and blood tests showing elevated alkaline phosphatase and decreased serum albumin.
- Treatment of choice is Praziquantel at 40 to 75 mg/kg in a single dose.
Evaluation of Incidental Liver Mass
-
Benign Liver Lesions:
- Hepatic Cysts
- Biliary Cystadenoma
- Hemangioma
- Adenoma
- Focal Nodular Hyperplasia
-
Malignant Liver Lesions:
- Hepatocellular Carcinoma
- Cholangiocarcinoma
- Metastatic Colorectal Cancer
Acute Liver Failure
- Etiologies include:
- Viral hepatitis (types B, A, E)
- Drug-induced liver damage, particularly from Acetaminophen.
- Clinical presentation features:
- Jaundice
- Encephalopathy
- Hepatic coma
- Elevated creatinine (>2 mg/dL)
- Abnormal arterial pH.
- Management involves:
- ICU admission and monitoring
- Liver biopsy if indicated
- Specific actions for acetaminophen overdose:
- Discontinue acetaminophen
- Administer activated charcoal
- Use N-acetylcysteine as an antidote.
Malignant Neoplasms of the Liver - Hepatocellular Carcinoma (HCC)
- Typically asymptomatic in early stages, often diagnosed at advanced stages.
- Symptoms may include jaundice, weight loss, malaise, and upper abdominal pain.
- Recommended screening populations:
- Individuals with liver cirrhosis
- Patients with Hepatitis B and C infections.
