THE IMPACT OF THE COVID-19 PANDEMIC ON ENDOSCOPIC ULTRASOUND PROCEDURES IN A HIGH-VOLUME ENDOSCOPY UNIT IN BRAZIL.

•In pancreatic neoplasms the EUS plays a key role in the management. •During the pandemic period, lockdown measures prevented patients with comorbidities from performing EUS. •The D-EUS decreased during COVID-19, while I-EUS increased and EUS-TA was the most commonly I-EUS procedure performed, with no increase in adverse events.

Endoscopic Ultrasound-Guided Tissue Acquisition Versus Fine Needle Aspiration for Diagnosis of Pancreatic Ductal Adenocarcinoma.

Objectives: Compare the 22G needle versus EchoTip ProCore® 20 (Cook Medical, Bloomington, IN, USA) on their handling, specimen suitability, amount of tissue obtained, diagnostic performance, the possibility of immunohistochemistry, and rate of adverse events.

Materials And Methods: This is a retrospective, comparative study of consecutively examined patients with pancreatic masses who underwent endosonography-guided fine needle aspiration (FNA) via the 22G needle, and endosonography-guided tissue acquisition (TA) via ProCore 20 (PC20). The operator evaluated needle insertion and subjectively classified the specimen.
