Biliary Obstruction Caused by Liver Fluke: A Comprehensive Guide

Health Insurance Plans Starts at Rs.44/day*

Biliary obstruction refers to a blockage in the tubes that carry bile from the liver to the gallbladder and small intestine. Liver fluke, specifically Fasciola hepatica, is a parasitic infection that can cause biliary obstruction.

Liver flukes are flatworm parasites that primarily infect the liver and bile ducts of various mammals, including humans. A blockage in the tubes that convey bile from the liver to the gallbladder and small intestine is referred to as biliary obstruction.

In some cases, this obstruction can be caused by a parasitic infection known as liver fluke. Flatworm parasites called liver flukes primarily affect the liver and bile ducts of different mammals, including humans.

Symptoms

When a person is infected with liver fluke, they may experience a range of symptoms related to biliary obstruction. These symptoms can include:

  • Right upper quadrant pain
  • Vomiting
  • Nausea
  • Jaundice (yellowing of the skin and eyes)
  • Fever
  • Abdominal distension

Diagnosis

The following diagnostic methods may be used:

Blood tests: These tests can detect elevated levels of bilirubin, liver enzymes and eosinophils, which are indicative of liver fluke infection.

Imaging studies: The bile ducts may be viewed using ultrasound, computed tomography (CT), or magnetic resonance imaging (MRI) scans to look for any obstructions or abnormalities.

Treatment

The treatment of biliary obstruction caused by liver fluke typically involves a combination of medications and procedures. The goals of treatment are to eliminate the parasite, relieve the obstruction and manage any complications.

The following treatment options may be considered:

Medications: Anthelmintic drugs, such as triclabendazole, are commonly used to kill the liver fluke and eliminate the infection.

Endoscopic procedures: In some cases, endoscopic retrograde cholangiopancreatography (ERCP) may be performed to remove the fluke or relieve the obstruction using specialized instruments.

Surgical intervention: Surgery may be required to remove the fluke and restore the normal flow of bile.

Prevention

Preventing biliary obstruction caused by liver fluke primarily involves avoiding exposure to contaminated water and raw or undercooked freshwater plants or animals. This can be achieved by:

  • Avoiding the consumption of raw or undercooked freshwater fish, crabs, or other aquatic animals.
  • Ensuring proper hygiene and sanitation practices, especially when handling or preparing food.
  • Drinking safe and clean water from reliable sources.

Complications and Prognosis

If left untreated, biliary obstruction caused by liver fluke can lead to various complications, including:

Cholangitis: Inflammation of the bile ducts.

Pancreatitis: Inflammation of the pancreas.

Liver abscess: Collection of pus within the liver.

The prognosis for individuals with biliary obstruction caused by liver fluke is generally favorable with appropriate treatment.

Conclusion

Biliary obstruction caused by liver fluke is a condition characterized by the blockage of the bile ducts due to an infection with Fasciola hepatica. By practicing good hygiene and avoiding consumption of contaminated food and water, the risk of liver fluke infection can be significantly reduced.
