HIGH PERFORMANCE OF A NEW FRANSEEN NEEDLE FOR ENDOSCOPIC ULTRASOUND-GUIDED FINE-NEEDLE BIOPSY IN SOLID LESIONS: A RETROSPECTIVE MULTICENTER STUDY

Endoscopic ultrasound-guided fine needle aspiration (FNA) is the standard choice to sample gastrointestinal/pancreatic lesions. EUS-FNA is accurate when rapid on-site evaluation (ROSE) is performed, but ROSE is not always available. EUS-guided fine needle biopsy (EUS-FNB) can give a a better chance to reach a diagnosis providing more tissue. It is not simple to use 19-gauge needles especially in transduodenal settings for risk of complications.A new needle for EUS-FNB, the AcquireTM needle is available from 2016. Data for pancreatic and non pancreatic solid lesions are available but these are based only on small sample size studies. The aim of our study is to perform a retrospective evaluation of all sampling procedures performed using the 22/25 gauge AcquireTM needle in patients with solid lesions.
