Background : Subepithelial lesions (SEL) on upper gastrointesti- nal endoscopy are frequently encountered and referred to endo- scopic ultrasound (EUS). Management of small gastric hypoechoic SELs of muscularis propria (MP) is controversial since EUS-assist- ed fine needle aspiration may be inconclusive, and surgical excision may be too invasive. We aimed to analyze our gastric MP-SELs in terms of survival and confounding factors. Methods : Data from gastric hypoechoic MP-SELs suggestive of gastrointestinal stromal tumor (GIST) by EUS were retrospective- ly reviewed. Surgically resected GISTs were stratified according to the current pathological risk criteria. Results : Sixty-one patients were identified. The mean age was 55.5 ± 13.2 years and 45.6% were male. Mean follow-up duration was 53.4 ± 26.7 (12-110) months. Twenty-eight (45.9%) patients were managed conservatively (diameter 15.3 ± 10.1 mm). There were no metastasis- or tumor-related deaths and no significant size changes (= 5 mm) in this group during follow-up. Thirty-three (54.1%) patients underwent complete resection (diameter 34.2 ± 14.1 mm) among which 25 (75.8%) had the final diagnosis of GIST ; 2 (8.0%), 14 (56%) and 6 (24%) patients were classified in no-risk, very-low-risk, low-risk categories respectively, while 2 (8.0%) were in moderate-risk and only 1 (4.0%) was in high-risk category. |
