- Abstract
Background and Aim: Ectopic pancreas is a common submucosal lesion in the stomach, but its histological diagnosis is usually difficult when tissue samples are obtained with a conventional biopsy forceps. The aim of this study was to describe the endosonographic features of gastric ectopic pancreas. Methods: We retrospectively analyzed a database of all patients who underwent endoscopic ultrasonography (EUS) at Pusan National University Hospital from July 2006 to August 2010. A total of 26 patients with histologically confirmed ectopic pancreas were included in the study. The EUS features of their lesions were analyzed. Results: Ten lesions were located in the antrum, and 16 lesions were located in the body. Nine lesions (34.6%) showed an umbilication or central dimpling on the surface, and a mural growth pattern was most commonly observed (61.5%). Twenty-four lesions (92.3%) showed hypoechoic echogenicity, and 13 lesions (50.0%) were heterogeneous. The borders were indistinct in 16 lesions (61.5%) and lobulated margins were observed in 16 lesions (61.5%). Anechoic cystic or tubular structures appeared in 17 lesions (65.4%), and 20 lesions (76.9%) involved two or more sonographic layers. Conclusions: The characteristic EUS features of ectopic pancreas are indistinct borders, lobulated margins, presence of anechoic duct-like structures, a mural growth pattern, and localization within two or more layers. These EUS features are potentially useful for differentiating ectopic pancreas from other mesenchymal tumors in the stomach.
