Study summary

The aim of this study is to compare the diagnostic accuracy of two EUS-guided tissue acquisition devices; the 19G Echotip Ultra Fine Needle Aspiration (FNA) device and the 20G Echotip ProCore Fine Needle Biopsy (FNB) device for the diagnosis of autoimmune pancreatitis.

Read the detailed description

Endoscopic ultrasound (EUS)-guided tissue acquisition has emerged as a valuable method to diagnose autoimmune pancreatitis (AIP) and exclude malignancy. During Endoscopic Ultrasound (EUS), tissue samples can be obtained for pathological evaluation with different devices. Previous studies suggest 19-gauge fine needle aspiration (FNA) needle provides a reliable specimen for diagnosis of AIP. However tissue architecture and cell morphology are essential for accurate pathological assessment. Therefore, pathologists generally prefer a histological specimen. Fine needle biopsy (FNB) has the advantage of obtaining a histological specimen, which may lead to better diagnostic performance. However, the superiority of histology over cytology in EUS-guided tissue sampling for diagnosis of AIP has not been proven yet. In this study, we aim to compare the diagnostic accuracy of two EUS-guided tissue acquisition devices; the 19G Echotip Ultra Fine Needle Aspiration (FNA) device and the 20G Echotip ProCore Fine Needle Biopsy (FNB) device for the diagnosis of autoimmune pancreatitis.

What researchers measure

Primary outcomes

  1. Diagnostic accuracy (compared to the gold standard diagnosis)

    Gold standard diagnosis is defined as: based on the conclusions of the diagnostic work-up (combined outcomes of tissue sampling and imaging studies), and confirmed by a compatible clinical disease course of at least 12 months

    Time frame: 24 months

Secondary outcomes

  1. Technical success

    tissue acquisition

    Time frame: 24 months

  2. Quality of the tissue sample

    Quality, defined as; presence of core tissue

    Time frame: within 2 weeks after the EUS procedure and after 24 months

  3. Quantity of the tissue sample

    Quantity, defined as; presence of remnant material after diagnosis was obtained and sufficiency for advanced diagnostic processing

    Time frame: within 2 weeks after the EUS procedure and after 24 months

  4. Diagnostic yield of the first needle pass

    Time frame: within 2 weeks after the EUS procedure and after 24 months

  5. Adverse events

    Safety

    Time frame: first 24 hours until - 24 months after procedure
