Area of Science:

Hepatobiliary medicine
Diagnostic imaging

Background:

Percutaneous transhepatic cholangiography (PTC) is crucial for diagnosing jaundice and hepatobiliary conditions.
It complements endoscopic retrograde cholangiopancreatography (ERCP) but offers advantages for proximal biliary lesions.

Purpose of the Study:

To evaluate the diagnostic utility and safety of PTC.
To highlight the benefits of ultrasound guidance in PTC procedures.

Main Methods:

The study reviews the application of PTC in diagnosing hepatobiliary and pancreatic diseases.
Emphasis is placed on the technique and safety protocols, including the use of ultrasound guidance.

Main Results:

PTC is highly effective for diagnosing obstructive jaundice and other hepatobiliary diseases.

Ultrasound guidance significantly reduces the number of punctures required and minimizes risks of complications like pneumothorax or vessel injury.

Conclusions:

PTC is a safe and valuable diagnostic tool when performed by experienced practitioners.
Ultrasound-guided PTC improves procedural efficiency and patient safety, making it superior for diagnosing lesions near the liver.
