Abstract
ABSTRACT
Background
Gastric subepithelial lesions (SELs) measuring
Methods
We retrospectively analyzed patients who underwent EUS‐TA for SELs at Tonan Hospital between June 2012 and March 2025. Variables including needle type, number of passes, histological diagnosis, and diagnostic accuracy were compared between SELs
Results
A total of 163 patients were included: 50 with SELs p
= 0.03). GIST was the most common diagnosis in both groups, with no significant difference (56% vs. 61.9%). Fine needle biopsy did not significantly improve sample adequacy or diagnostic accuracy. Diagnostic accuracy for SELs
Conclusions
EUS‐TA with ROSE for gastric SELs <20 mm yields diagnostic accuracy comparable to that for SELs ≥20 mm. Given the high GIST prevalence in small SELs, EUS‐TA may be a valuable diagnostic strategy.
