How to do pancreatic mass FNA

Area of Science:

• Gastroenterology
• Oncology
• Diagnostic Imaging

Background:

• Fine-needle aspiration (FNA) is crucial for diagnosing and managing pancreatic masses.
• Endoscopic ultrasound-guided FNA (EUS-guided FNA) accuracy for pancreatic masses typically ranges from 71% to 90%.

Purpose of the Study:

• To review the diagnostic utility and technical considerations of EUS-guided FNA for pancreatic masses.
• To highlight factors influencing the diagnostic yield of EUS-guided FNA.

Main Methods:

• Review of clinical data, including cross-sectional imaging, prior to endoscopy.
• EUS-guided FNA performed under direct visualization, with attention to needle selection based on lesion characteristics.
• Sampling techniques such as multi-planar acquisition and targeting specific mass regions.
• Consideration of Rapid On-Site Evaluation (ROSE).

Main Results:

• EUS-guided FNA accuracy for pancreatic masses is between 71% and 90%.
• Pre-procedure review of clinical data and imaging is essential.
• Needle choice depends on lesion location and size.
• Optimizing sampling strategy and utilizing ROSE can enhance diagnostic success.

Conclusions:

• EUS-guided FNA is a key tool in the evaluation of pancreatic masses.
• Careful technique, including pre-procedure assessment and optimized sampling, is vital for maximizing diagnostic accuracy.
• ROSE can further improve the yield of EUS-guided FNA for pancreatic lesions.
