This study aimed to compare the diagnostic yield of mucosal incision-assisted biopsy (MIAB) and endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) with a rapid on-site evaluation (ROSE) for gastric subepithelial lesions (SEL) suspected being gastrointestinal stromal tumors (GIST) an intraluminal growth pattern.This was prospective randomized, cross-over multicenter study. The primary outcome EUS-FNA MIAB. secondary outcomes were technical success rate, complication procedure time frequency.A total 47 patients randomized MIAB group (n = 23) 24). There no significant difference in (91.3% vs 70.8%, P 0.0746). rates did not differ statistically extent. mean significantly longer than that (34 26 min, 0.0011).The satisfactorily as high ROSE SEL pattern.
