ABSTRACT

Objective To evaluate the value of endoscopic ultrasound (EUS) in differentiatied diagnosis for stromal tumour and lipoma in duodenal tract.MethodsThe EUS images of 44 cases of stromal tumour(30 cases) and lipoma( 14 cases) which were confirmed by pathological results were analyzed retrospectively.The location,size,layer of origin,margin,internal echo pattern and homogeniety of the lesion were recorded and compared.Results Compared with lipoma,stromal tumour showed a significant difference in the layer of origin,margin,internal echo and homogeniety ( P ＜ 0.05 ),but there was no statistical difference in the lesion location and size( P ＞0.05).ConclusionsEUS is greatly helpful to the differential diagnosis of stromal tumour and lipoma in duodenal tract.
