title: Endosonogragphic features of lesions suggesting gastricectopic pancreas: experience of a single tertiary center.
abstract: We aimed to present the endoscopic ultrasound (EUS) features of gastric lesions suggesting gastric ectopic pancreas during upper gastrointestinal endoscopy that were diagnosed in our gastroenterology unit, which is a tertiary center for endoscopic procedures in Turkey.
  
  
  
  The data of patients who underwent upper gastrointestinal EUS in our center between April 2012 and July 2014 were retrospectively analyzed.
  
  
  
  All of the lesions suggesting gastric ectopic pancreas were localized in the gastric antrum. Thirty-six of 44 lesions (81.1%) showed central dimpling. Lesion borders were shown to be definite in 10 (22.7%) lesions, whereas the borders of 34 lesions (77.3%) were indefinite. Thirty-nine lesions (88.6%) had heterogeneous and 5 lesions (11.4%) had homogeneous echo patterns; whereas 29 lesions (65.9%) were hypoechoic, 9 lesions (20.5%) were hyperechoic and 6 lesions (13.6%) had mixed echogenicity. Forty-two lesions (95.5%) were shown to affect only a single sonographic layer of the gastric wall.
  
  
  
  EUS features of lesions that strongly suggest gastric ectopic pancreas endoscopically, without any histopathological evidence and without either endoscopic or surgical resection, are as follows: indefinite border appearance, minimal heterogeneous hypoisoechoic echo pattern, existence of anechoic duct-like structures inside the lesion, common localization in the submucosal layer, and existence of umbilication.
