Summary
Endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) now offers core tissue acquisition for gastrointestinal tumors. New needles improve maneuverability and sample quality for molecular diagnostics.
Area of Science:
- Gastroenterology and Endoscopy
- Oncology
- Pathology
Background:
- Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is standard for gastrointestinal tumor diagnosis.
- There is a growing trend towards EUS-guided fine needle biopsy (EUS-FNB) for core tissue acquisition, driven by molecular marker-based chemotherapy and the need for reliable diagnoses without onsite cytopathologists.
Purpose of the Study:
- To review advancements in EUS-guided tissue acquisition techniques.
- To highlight the development and utility of new needles for EUS-FNB.
Main Methods:
- Discussion of the evolution from rigid Trucut needles to newer ProCore needles with reverse bevel technology.
- Mention of flexible 19-gauge needles designed for improved maneuverability in the transduodenal route.
Main Results:
- New needle technologies, like the ProCore needle, aim to overcome limitations of traditional biopsy needles.
- Flexible 19-gauge needles demonstrate capability for core tissue procurement and ease of navigation.
Conclusions:
- Optimal clinical outcomes in EUS-FNB depend on evidence-based techniques.
- Procuring adequate sample size for ancillary studies and appropriate specimen processing are crucial for successful diagnosis and treatment planning.
