Abstract：Objective To evaluate the value of endoscopic ultrasonography (EUS) in diagnosing gastric heterotopic pancreas.Methods Imaging data of 51 patients with gastric heterotopic pancreas diagnosed by EUS from January 2012 to June 2015 were retrospectively analyzed.The electrogastroscope manifestation (including size, location, mucosal bridge plica, pitpattern or umbilication), the EUS features (including origin, border and echo) and the pathological findings were recorded.Results The lesion was single in all 51 patients;the mucosal surface was smooth;the mucous bridge was not found;the long diameter was (15 ± 10) mm (6-42 mm).The lesion located at gastric antrum in 42 cases (82.4％) showing as disc bulge, at gastric body in 9 cases (17.6％) showing as hemispheric sticks;there was pitpattern or umbilication in 29 cases (56.9％).EUS showed that the heterotopic pancreas originated from mucosa lamina propria in 1 cases (2.0％), from submucosa in 44 cases (86.3％), from muscularis propria in 4 cases (7.8％) , from subserosa in 1 cases (2.0％) and from submucosamuscularis propria in 1 cases (2.0％);the boundary was clear in 49 lesions (96.1％);28 lesions (54.9％)manifested as mixed echo, 23 lesions (45.1％) manifestaed as medium-high inhomogenous echo;tubularstructure was found in 22 lesions (43.1％), cysts cavity structure was found in 2 lesions (3.9％).Totally 21 cases (41.2％) were pathologically confirmed.Conclusion EUS can accurately reveal the origin and internal echo pattern of gastric heterotopic pancreas and is valuable in diagnosing gastric heterotopic pancreas.
