Endoscopic ultrasonography (EUS) helps determine malignancy risk in submucosal lesions. This review covers EUS features, biopsy techniques, and management strategies for these gastrointestinal findings.

Area of Science:

  • Gastroenterology
  • Medical Imaging
  • Oncology

Background:

  • Submucosal lesions found during endoscopy are often benign, but the potential for malignancy necessitates careful evaluation.
  • Accurate diagnosis is crucial for guiding patient management and treatment strategies.

Purpose of the Study:

  • To review the current role of endosonography in managing gastrointestinal submucosal lesions.
  • To focus on assessing the risk of malignancy using endoscopic ultrasonography (EUS).

Main Methods:

  • Review of current literature on endosonography for submucosal lesions.
  • Discussion of diagnostic features and predictive value of endoscopic ultrasonography (EUS).
  • Evaluation of EUS-guided fine needle biopsy (FNB) capabilities and limitations.

Main Results:

  • EUS features and their combinations offer predictive value for malignancy risk.
  • EUS-guided FNB has specific capabilities and limitations in diagnosing submucosal lesions.
  • Distinguishing extraluminal compressions from true submucosal lesions is addressed.
  • EUS-assisted endoscopic removal and catheter-based endosonography roles are discussed.
  • Pathologic classification changes for gastrointestinal mesenchymal tumors impact EUS management.

Conclusions:

  • Endoscopic ultrasonography (EUS) is a key tool in evaluating submucosal lesions and determining malignancy risk.
  • EUS aids in differentiating benign from malignant lesions, guiding treatment decisions, and managing patients not suitable for surgery.
  • Understanding EUS capabilities and limitations is essential for optimal patient care.
