BACKGROUND AND STUDY AIMS The study aimed to investigate whether the 25G needle is superior to the 22G needle when used in endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of solid lesions. PATIENTS AND METHODS The study was a single-center randomized clinical trial. The setting was a tertiary referral hospital, where EUS-FNA of solid lesions was assisted by an on-site cytopathologist, who was blinded to the needle size. The main end point was the number of passes performed to… CONTINUE READING
