EFSUMB Guidelines on Interventional Ultrasound (INVUS), Part IV - EUS-guided interventions: General Aspects and...

Area of Science:

• Gastroenterology
• Medical Imaging
• Interventional Endoscopy

Background:

• Endoscopic ultrasound (EUS) integrates advanced imaging with tissue acquisition for gastrointestinal lesions.
• EUS-guided sampling offers a minimally invasive approach for diagnosing lesions within and near the gastrointestinal tract.

Purpose of the Study:

• To provide comprehensive guidelines on endoscopic ultrasound-guided diagnostic and therapeutic interventions.
• To assess the evidence supporting endoscopic ultrasound-guided sampling.
• To offer clinical practice recommendations for EUS-guided sampling procedures.

Main Methods:

• Review of current evidence on EUS-guided sampling.
• Assessment of indications, contraindications, techniques, and adverse events.
• Comparison of EUS-guided biopsy with image-guided percutaneous biopsy.
• Evaluation of training requirements and clinical impact.
• Analysis of principles and reliability of cytopathological reporting.

Main Results:

• EUS-guided sampling is a safe and effective method for tissue acquisition.
• The guideline provides crucial recommendations for preconditions, procedural steps, and safe performance.
• Evidence supports the use of EUS-guided sampling for various gastrointestinal lesions.
• Comparison highlights advantages and drawbacks relative to percutaneous biopsy.

Conclusions:

• Endoscopic ultrasound-guided sampling is a valuable tool for gastrointestinal lesion diagnosis.
• The guideline establishes best practices for EUS-guided sampling and cytopathological reporting.
• Adherence to these guidelines ensures safe and effective patient care.
