Abstract:
Background/Aims:Distinguishing gastric ectopic pancreas (GEP) from malignant tumors is relatively difficult. This study evaluated the endosonography findings of pathologically proven GEP.
Methods:Thirty-one patients diagnosed with GEP based on a histopathological analysis from January 2004 to July 2018 were enrolled in this study. All patients underwent EUS and an endoscopic resection.
Results:Seventeen patients were female, and the median age was 41.1 years (range, 14-74). The lesions were localized most commonly in the antrum. The mean size of the GEP was 10.6 mm (range, 7-15). Superficial type lesions, lesions with heterogeneous echogenicity, mixed pattern lesions, and lesions with indistinct borders were commonly observed on EUS. Calcification, anechoic duct-like structures, and thickening of the muscularis propria were observed in some patients. Endoscopic mucosal resection (41.9%) and endoscopic submucosal dissection (58.1%) were performed. The mean procedure time was 22.5 minutes. Complete resection was achieved for 71% of patients. No statistically significant results between the endosonography findings and complete resection rates were obtained. The mean follow-up esophagogastroduodenoscopy duration was 4.5 months. None of the patients presented with residual lesions on subsequent endoscopy.
Conclusions:EUS can help identify the features of GEP. Careful observations of the EUS findings can avoid unnecessary removal of GEP.
