Endoscopic ultrasound-guided biliary interventions: an update on recent developments.

Area of Science:

• Gastroenterology
• Interventional Endoscopy
• Biliary Interventions

Background:

• Endoscopic ultrasound (EUS)-guided biliary drainage offers solutions for complex biliary obstruction cases.
• Indications include prior failed interventions, inaccessible ampulla, and surgically altered anatomy.
• Advancements in techniques and accessories are improving procedural efficiency.

Purpose of the Study:

• To review recent literature on EUS-guided biliary drainage.
• To highlight key findings and evolving strategies in the field.
• To clarify optimal techniques and indications for EUS-guided biliary interventions.

Main Methods:

• Literature review of recent studies on EUS-guided biliary drainage.
• Analysis of effectiveness and safety data for various EUS-guided drainage techniques.
• Synthesis of current evidence on gallbladder and bile duct drainage.

Main Results:

• EUS-guided gallbladder drainage is effective as a primary or secondary intervention for cholecystitis.
• EUS-guided bile duct drainage can be achieved through multiple techniques.
• The safety and efficacy of these procedures are supported by recent literature.

Conclusions:

• The application of EUS-guided biliary drainage is expanding.
• Recent literature focuses on defining optimal strategies and indications.
• Further research is needed to refine technique selection based on clinical scenarios.
