Endoscopic ultrasound guided biliary drainage

Area of Science:

• Gastroenterology
• Interventional Endoscopy

Background:

• Endoscopic retrograde cholangiopancreatography (ERCP) is standard for biliary and pancreatic duct stenosis.
• ERCP stent placement can fail due to anatomical challenges and impacted stones.
• Alternative drainage methods like PTBD and surgery have significant risks.

Purpose of the Study:

• To review the efficacy and safety of endoscopic ultrasonography-guided biliary drainage.
• To evaluate EUS-guided biliary drainage as an alternative to ERCP failure.

Main Methods:

• Literature review of published data on EUS-guided biliary drainage.
• Analysis of techniques including direct access and rendezvous procedures.
• Assessment of technical success rates and complication profiles.

Main Results:

• EUS-guided biliary drainage demonstrates technical success rates between 75%-100%.
• The procedure is associated with a low rate of complications.
• It serves as a viable alternative to percutaneous trans-hepatic biliary drainage (PTBD).

Conclusions:

• Endoscopic ultrasonography-guided biliary drainage is an effective and safe alternative for patients with failed ERCP.
• This technique offers a less invasive option compared to PTBD or surgery.
• EUS-guided drainage expands treatment options for complex biliary and pancreatic duct stenosis.
