Gastrointestinal endoscopy·2025

Endoscopic ultrasound (EUS) is the leading imaging tool for gastrointestinal cancer staging. Its fine-needle aspiration (FNA) offers high accuracy for nodal staging and is expanding into new diagnostic and therapeutic applications.

Area of Science:

  • Gastroenterology and Oncology
  • Medical Imaging
  • Interventional Endoscopy

Background:

  • Endoscopic ultrasound (EUS) is the most accurate imaging modality for locoregional staging of gastrointestinal (GI) cancers.
  • Fine-needle aspiration (FNA) enhances nodal staging accuracy, particularly for luminal and pancreaticobiliary diseases.

Purpose of the Study:

  • To review the current clinical applications of EUS in GI oncology.
  • To explore novel diagnostic and interventional uses of EUS-FNA technology.

Main Methods:

  • Review of current literature on EUS applications in GI oncology.
  • Evaluation of emerging non-GI indications and interventional procedures using EUS-FNA.

Main Results:

  • EUS-FNA achieves high accuracy (90% range) in nodal staging for GI cancers.
  • EUS-FNA is being investigated for non-small cell lung carcinoma and posterior mediastinum evaluation.
  • Interventional applications include EUS-guided celiac plexus neurolysis and fine-needle injection.

    • Conclusions:

    • EUS is a cornerstone in GI cancer staging and diagnosis.
    • EUS-FNA presents expanding roles in both diagnostic accuracy and therapeutic interventions.
    • Future directions involve broader applications in oncology and interventional procedures.
