Area of Science:

  • Gastroenterology and Oncology
  • Diagnostic Imaging and Interventional Procedures

Background:

  • Pancreatic masses present diagnostic challenges due to complexities in tissue acquisition.
  • Endoscopic ultrasound (EUS)-guided tissue acquisition has become a key method for accessing pancreatic lesions.

Purpose of the Study:

  • To review tissue acquisition techniques for pancreatic tumors.
  • To explore factors influencing diagnostic accuracy and specimen adequacy.

Main Methods:

  • Narrative review of EUS-guided tissue acquisition methods.
  • Assessment of needle designs, maneuvers, and tissue preparation techniques.
  • Consideration of percutaneous ultrasound-guided biopsy and on-site evaluation.

Main Results:

  • Diagnostic accuracy varies with tumor characteristics and procedural factors.
  • Tailored approaches to tissue preparation are crucial.
  • On-site evaluation aids specimen adequacy.
  • Percutaneous biopsy is an alternative when EUS is not feasible.

Conclusions:

  • Optimizing tissue acquisition is vital for accurate pancreatic tumor diagnosis.
  • Emerging trends include using tissue for genetic and molecular analysis.
  • Future directions focus on integrating advanced techniques into clinical practice.
