Therapeutic EUS: New tools, new devices, new applications

Area of Science:

• Gastroenterology
• Interventional Endoscopy
• Medical Devices

Background:

• Linear echoendoscopes facilitate endoscopic ultrasound (EUS)-guided interventions near the gastrointestinal tract.
• Advancements in EUS tools and devices expand procedural applications, improving safety and efficacy.

Purpose of the Study:

• To review the latest developments in therapeutic EUS over the past four years.
• To highlight novel devices and techniques enhancing EUS-guided interventions.

Main Methods:

• Review of recent literature on therapeutic EUS.
• Focus on new devices including biopsy needles, stents, and stent insertion systems.
• Analysis of applications such as biliary drainage, pancreatic fluid collection management, and anastomosis creation.

Main Results:

• New biopsy needles increase histology yield and reduce passes.
• Specialized stents enable effective bile duct and gallbladder drainage.
• EUS-guided biliary drainage is a safe alternative when ERCP fails.
• Transmural stenting is preferred for peripancreatic fluid collections.
• Lumen-apposing stents facilitate gastrojejunostomy and gastrogastrostomy.
• EUS shows expanding roles in tumor ablation and angiotherapy.

Conclusions:

• Therapeutic EUS has significantly advanced with new technologies.
• These innovations enhance the safety and efficacy of minimally invasive gastrointestinal procedures.
• EUS-guided interventions are becoming increasingly crucial in managing complex gastrointestinal conditions.
