Endoscopic ultrasound (EUS) advancements enable precise biopsies and interventions for various conditions. EUS-guided procedures offer high accuracy and reduced pain, improving patient outcomes.
Area of Science:
- Gastroenterology
- Interventional Endoscopy
- Medical Imaging
Background:
- Sectorial linear endoscopic ultrasound (EUS) has undergone a decade of development.
- Interventional EUS has emerged, facilitated by echoendoscopes with large working channels.
Purpose of the Study:
- To review the advancements and applications of EUS-guided interventions.
- To highlight the efficacy of EUS-guided biopsy and therapeutic procedures.
Main Methods:
- Review of EUS-guided biopsy for lymph nodes, mediastinal masses, and pancreatic tumors.
- Description of EUS-guided celiac plexus block and cystoenterostomy.
- Mention of the new EG 38X echoendoscope with a 3.8 mm working channel.
Main Results:
- EUS-guided biopsy demonstrates high sensitivity (76-91%), specificity (84-100%), and accuracy (78-94%).
- EUS-guided celiac plexus block significantly reduces pain (85-90% of cases).
- EUS-guided cystoenterostomy allows accurate drainage with reduced risks.
Conclusions:
- EUS-guided interventions are effective for diagnosis and treatment of various gastrointestinal and pancreatic conditions.
- Newer echoendoscopes enhance the capabilities for complex interventional procedures.
- EUS offers a minimally invasive approach with significant clinical benefits.
