Endoscopic ultrasonography (EUS) is a highly accurate diagnostic tool for various conditions. Its integration with fine-needle aspiration enhances tissue diagnosis and patient outcomes.

Area of Science:

  • Gastroenterology and Endoscopy
  • Medical Imaging
  • Oncology

Background:

  • Endoscopic ultrasonography (EUS) has been clinically utilized for nearly two decades.
  • It is now a standard technique in hospital practice, supported by over 2000 publications.
  • EUS instrumentation involves a modified endoscope with a high-frequency ultrasound transducer.

Purpose of the Study:

  • To review the diagnostic and staging capabilities of EUS.
  • To highlight its clinical applications and impact on patient outcomes.
  • To emphasize the role of fine-needle aspiration (FNA) as an adjunct to EUS.

Main Methods:

  • Review of scientific literature on EUS applications.
  • Description of EUS instrumentation and capabilities.

  • Discussion of EUS in diagnostic and staging algorithms.

    • Main Results:

    • EUS demonstrates high accuracy in diagnosing and staging benign and malignant conditions.
    • Its ability to visualize multi-layer gut wall structure and surrounding lesions (pancreatobiliary area, masses, lymph nodes) is key.
    • Fine-needle aspiration (FNA) since 1993 has enabled feasible and safe tissue diagnosis for EUS-accessible lesions.

    Conclusions:

    • EUS is a validated, cost-effective tool significantly impacting patient outcomes.
    • Its integration into diagnostic and staging algorithms is well-established.
    • EUS, particularly with FNA, is indispensable for evaluating gastrointestinal and related pathologies.
