Current status of endosonography-guided biliary drainage

Area of Science:

• Gastroenterology
• Interventional Radiology

Background:

• Obstructed biliary systems typically require drainage via endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous transhepatic biliary drainage (PTBD).
• ERCP and PTBD are invasive procedures with associated risks and limitations.

Purpose of the Study:

• To review the current status of endosonography-guided biliary drainage (EGBD) as an alternative therapeutic option.
• To highlight the evolving role of endosonography in interventional procedures.

Main Methods:

• Review of current literature on EGBD.
• Analysis of EGBD as an alternative to PTBD.

Main Results:

• Endosonography, once diagnostic, now offers therapeutic capabilities.
• EGBD is emerging as a viable alternative to PTBD for biliary drainage.
• This technique is still evolving and requires further development for routine clinical use.

Conclusions:

• EGBD represents a significant advancement in minimally invasive biliary interventions.
• Further research and standardization are needed to establish EGBD as a routine clinical practice.
