ABSTRACT
Objective To describe the characteristic endoscopic ultrasonography (EUS) features of gastric ectopic pancreas.Methods Totally 23 patients were diagnosed pathologically as having gastric ectopic pancreas.The EUS images of the lesions were retrospectively reviewed regarding layer of origin,size,growth pattern,margin,and internal echo pattern.Results The coincidence of EUS and pathologic diagnosis was 91%(21/23).EUS revealed that the lesions originated from the second,third,and/or fourth layers of the gastric wall.Most lesions were heterogenous,mainly isoechoic.The borders of the lesions were indistinct in 70%(16/23) patients. Anechoic cystic or tubular structures within the lesions appeared in 10 of the 23 lesions(43%).The mean longest/shortest diameter ratio of ectopic pancreas was 1.7.Conclusions Characteristic EUS features of gastric ectopic pancreases includemural lateral growth pattern,third layer (submucosa) origin,indistinct margin,intermediate echogenecity,anechoic areas,and fourth-layer thickening.Careful assessment of the EUS findings may be a useful aid in the diagnosis of gastric ectopic pancreas.
