Summary
Brief summary (as posted)
The present study aims at comprehensively assessing the diagnostic performance and safety profile of EUS-FNB as a primary diagnostic tool for suspected malignancies in anatomically complex or deeply situated regions, including the duodeno-jejunal, and hepatic hilar areas. By focusing on lesions that are challenging to reach due to their intricate anatomy or profound depth, investigators seek to provide valuable insights into the potential role of EUS-FNB in enhancing diagnostic accuracy and safety in these complex clinical scenarios.

- measure
- Diagnostic accuracy of eus fnb
- timeFrame
- At 6 months after EUS-FNB, or at the time of surgical histopathologic diagnosis if surgery occurred earlier
- description
- Diagnostic accuracy, calculated according to the formula = (true positives + true negatives) / (true positives + false positives + true negatives + false negatives), of EUS-FNB for all the difficult-to-detect abdominal lesions.
