USG Guided Liver Biopsy

Overview

usg-over-view-img.webp

Ultrasound (USG) guided liver biopsy is a minimally invasive procedure used to obtain a small sample of liver tissue for diagnostic purposes. It helps in diagnosing liver diseases such as hepatitis, fibrosis, cirrhosis, and liver cancer. The use of ultrasound guidance improves accuracy and reduces complications compared to blind biopsy techniques.

Steps of the Procedure

Preparation:

  • Review patient history and lab reports.
  • Position the patient appropriately.
  • Clean and sterilize the biopsy site.

Ultrasound Guidance:

  • Locate the liver and determine the best biopsy site.

Local Anesthesia Application:

  • Inject lidocaine to numb the area.
  • Needle Insertion and Tissue Extraction
  • Introduce the biopsy needle and retrieve a liver sample.
  • Needle Removal and Dressing
    • Remove the needle carefully and apply pressure to prevent bleeding.
    • Cover with a sterile dressing.
    • Post-Procedure Monitoring
    • Observe the patient for 2-4 hours for complications.
    • Check vitals and manage any discomfort.

How is USG Guided Liver Biopsy Done?

Pre-Procedural Assessment
  • Complete medical history and physical examination.
  • Blood tests to check clotting function (PT, INR, Platelet count).
  • Imaging studies (Ultrasound, CT scan, MRI) to locate the biopsy site.
Patient Instructions:
  • Fasting for at least 6 hours before the procedure.
  • Stopping blood-thinning medications (aspirin, warfarin, etc.) as per doctor’s advice.
  • Arranging for someone to drive the patient home post-procedure.

Patient Positioning:
  • The patient lies on their back (supine) with the right arm raised above the head.
Local Anesthesia:
  • The skin over the biopsy site is cleaned and numbed with a local anesthetic.
Ultrasound Guidance:
  • A high-frequency ultrasound probe is used to visualize the liver and identify the safest approach.
Biopsy Needle Insertion:
  • A specialized needle is inserted through the skin into the liver under ultrasound guidance.
  • A small tissue sample is extracted for analysis.
Post-Biopsy Monitoring:
  • The patient is observed for a few hours to check for complications such as bleeding or pain.
  • Vital signs are monitored, and a follow-up ultrasound may be performed.

While USG-guided liver biopsy is generally safe, potential complications include:
  • Bleeding (Hemorrhage) – Rare but can occur, especially in patients with clotting disorders.
  • Pain – Mild to moderate pain at the biopsy site, which usually resolves within a few hours.
  • Infection – Very rare, but possible if sterility is compromised.
  • Pneumothorax – Accidental injury to the lung, though uncommon.
  • Bile Leak – Rare but can lead to localized infection or pain.

What are the Benefits of USG Guided Liver Biopsy ?
  • High Accuracy – Real-time ultrasound imaging ensures precise needle placement.
  • Minimally Invasive – No need for open surgery, reducing recovery time.
  • Reduced Complications – Lower risk of bleeding and organ injury.
  • Quick Recovery – Most patients can go home the same day.

Infrastructure Facilities

  • Ultrasound Machine with a high-resolution probe.
  • Biopsy Needles – Automated or manual core biopsy needles.
  • Sterile Procedure Kit – Drapes, gloves, antiseptics, local anesthetics.
  • Emergency Resuscitation Equipment – Oxygen supply, IV fluids, medications.
  • Observation Ward – For post-biopsy monitoring of patients.

FAQs

The actual biopsy takes about 10-15 minutes, but the total process, including preparation and monitoring, lasts a few hours.

Local anesthesia is used to minimize discomfort. Some patients may feel mild pressure or pain afterward.

Most patients can return to normal activities within 24-48 hours, avoiding heavy lifting for a few days.

Severe pain, persistent bleeding, fever, or shortness of breath should be reported to a doctor immediately.

Results typically take a few days to a week, depending on the laboratory.
