Same Session Validation of a Custom-Built 22G With the Commercial 25G System for EUS-Guided Portal Pressure Gradient Measurement.

Key Result

The custom-built 22G EUS-PPG system matches the commercial 25G system in portal pressure gradient measurement accuracy and offers better quality control and cost-efficiency.

Key Points

• The study aims to validate a custom-built 22G EUS-PPG system against a commercial 25G system.
• Conducted EUS-PPG measurements with both 25G and custom-built 22G systems
• Compared the accuracy and efficiency of both systems in real-time measurements
• The custom-built 22G system showed superior quality control via pressure tracing
• Demonstrated cost-efficiency compared to the commercial 25G system
