Abstract:
Objective To evaluate endoscopic ultrasonography (EUS) for diagnosis of gastric stromal tumors (GST) by analyzing EUS features of tumors with different invasive capacities.Methods Clinical data of 34 patients with GST were analyzed retrospectively.The tumors were classified according to Fletcher′s GIST biological behavior ranking system and the corresponding EUS features were analyzed.Results The mean maximal diameter of GST in this cohort was 6.7cm.The echo heterogeneity, big tumors size, irregular shape and ulceration were more common in tumors of high risk (P<0.05).Conclusion Tumor size, shape, echo quality and ulceration detected by EUS are useful features for pretreatment evaluation of GST, and can guide the choice of following managements.
