What this trial studies

This clinical trial aims to evaluate the diagnostic performance of contrast-enhanced endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) compared to conventional EUS-FNB for solid pancreatic lesions. The study will involve patients referred for tissue acquisition of pancreatic lesions larger than 1 cm, utilizing advanced techniques such as macroscopic on-site evaluation to assess specimen adequacy. The goal is to determine which method provides better diagnostic accuracy and specimen quality for further histological analysis.

Who should consider this trial

Good fit: Ideal candidates are individuals referred for EUS-guided tissue acquisition of solid pancreatic lesions greater than 1 cm.

Not a fit: Patients with coagulopathy, altered anatomy, contraindications for conscious sedation, or those unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic accuracy for pancreatic lesions, enabling better treatment decisions for patients.

How similar studies have performed: Previous studies have shown promising results with similar techniques, although this specific comparison is novel.
