Interventional Endoscopic Ultrasound: Current Status and Future Directions

Area of Science:

• Gastroenterology
• Interventional Endoscopy
• Medical Technology

Background:

• Endoscopic ultrasound (EUS) has evolved from diagnostic to therapeutic applications.
• New techniques and devices are expanding EUS capabilities for disease management, reducing the need for surgical or percutaneous procedures.
• Challenges include lack of formal training, data, and clinical implementation guidelines.

Purpose of the Study:

• To discuss the published literature on interventional EUS.
• To outline a framework for implementing interventional EUS techniques into clinical practice.
• To address key areas: EUS-guided access, tumor ablation, and endohepatology.

Main Methods:

• A White Paper generated from the American Gastroenterological Association's 2019 Tech Summit.
• Discussion of published literature on interventional EUS.
• Identification of key components and challenges in the field.

Main Results:

• Interventional EUS offers a paradigm shift in disease management.
• Key areas include EUS-guided access, tumor ablation, and endohepatology.
• Need for improved tools, safety/outcomes data, and endoscopist training identified.

Conclusions:

• Widespread adoption of interventional EUS requires support from GI societies, stakeholders, and payers.
• Development of training programs, equipment, and supportive policies is essential.
• Continued collaboration among societies and manufacturers will drive the growth of interventional EUS.
