Real-time endoscopic ultrasound-guided aspiration biopsy offers a safe and effective method for diagnosing malignant lesions. This technique achieved high specificity in identifying cancer, aiding in pathological diagnosis with simplicity.

Area of Science:

  • Gastroenterology
  • Oncology
  • Medical Imaging

Background:

  • Endoscopic ultrasound (EUS) is crucial for diagnosing gastrointestinal lesions.
  • Accurate pathological diagnosis is essential for guiding cancer treatment.

Purpose of the Study:

  • To evaluate the efficacy of real-time aspiration biopsy (AP) using linear echoendoscopy for diagnosing malignant lesions.
  • To determine the diagnostic accuracy and safety of this minimally invasive procedure.

Main Methods:

  • Aspiration biopsy (AP) was performed in 6 patients using a Pentax-Hitachi FG 32UA linear echoendoscope.
  • Lesions included pancreatic neoplasms, plastic linitis, and celiac trunk adenopathy.

Main Results:

  • Malignancy was confirmed in all cases through clinical follow-up or surgery.

  • The diagnostic sensitivity was 67%, specificity 100%, and diagnostic certainty 87%.
  • No complications were reported during the procedures.

    • Conclusions:

    • Real-time aspiration biopsy with linear echoendoscopy is a safe and effective tool for pathological diagnosis of suspected malignant lesions.
    • The procedure is relatively simple to perform, offering high specificity in cancer detection.
