    Summary

    Fine needle aspiration biopsy (FNAB) of the pancreas aids intraoperative diagnosis for surgical patients. This minimally invasive technique offers high accuracy and a low risk factor for differentiating benign and malignant pancreatic conditions.

    Area of Science:

    • Gastroenterology
    • Surgical Pathology
    • Cytopathology

    Context:

    • 10-15% of surgical patients with pancreatic disorders require intraoperative diagnosis.
    • Preoperative diagnoses are often inconclusive for pancreatic conditions.
    • Accurate intraoperative assessment is crucial for guiding surgical decisions.

    Purpose:

    • To evaluate the efficacy and safety of intraoperative fine needle aspiration biopsy (FNAB) of the pancreas.
    • To determine the diagnostic accuracy of FNAB in differentiating malignant and benign pancreatic processes.
    • To compare FNAB with traditional histological methods for pancreatic lesion diagnosis.

    Summary:

    • 244 pancreatic FNABs were performed on 100 patients, achieving a diagnostic statement in 99% of cases.

  • Cytological diagnosis was correct in 83% of cases, with a 7% false-negative rate and no false-positive cancer diagnoses.
  • FNAB demonstrated a low risk factor, with no major postoperative complications and transient hyperamylasemia in 25% of patients.

    • Impact:

    • FNAB is recommended over histological tissue removal due to its lower risk profile.
    • This technique provides a reliable basis for intraoperative differentiation of pancreatic pathologies.
    • Effective for diagnosing challenging pancreatic cases, improving patient management and surgical outcomes.
