EVALUATION OF ENDOSCOPIC ULTRASOUND-GUIDED FINE-NEEDLE ASPIRATION AND FINE NEEDLE BIOPSY IN SOLID PANCREATIC NEOPLASM IN LOW VOLUME HOSPITAL

Aims In recent years new technology has been introduced in needles to improve tissue acquisition and thus ameliorate the diagnostic yield in pancreatic neoplasms. This improvement may be more important in less experienced endosonographer. We performed a retrospective study to determine the difference in diagnostic yield between 22 G Fine-Needle Aspiration (FNA) and 22 G Fine-Needle biopsies (with the Franseen tip needle) (FNB) in the study of solid tumours of the pancreas.

Methods From august 2014 to September 2019, 434 endoscopics ultrasounds (EUS) studies were performed by the same endosonographer. The endosonographer does less than 150 EUS per year.

56 successive patients with solids tumours of the pancreas>10 mm were studied by FNA or FNB.

Results The diagnostic yield in the FNA group was 78.5% and 92.8% in the FNB group. Histologic diagnostic was obtained in 26 of the 28 FNB performed. In the FNA group, two diagnosis were obtained only in the cytologic evaluation. In the other arm all diagnosis were done by histology.

Conclusions There has been an improvement in the diagnostic yield in our series with the use of FNB needle. We also have seen that all the diagnosis where obtained by histology on this group. FNB allows us to obtain more tissue therefore to have a better diagnostic yield. This might be important for less experienced endosonographer and maybe also for pathologist that are less familiar with the cytology.
