Description
Background Although pancreatic rests have characteristic endoscopic features, confirming a histological diagnosis may be desirable to exclude other significant pathology. Aims The aim of this study was to assess the efficacy and safety of endoscopic band ligation snare polypectomy (EBLSP) for removal of suspected pancreatic rests and to compare the diagnostic yield to other endoscopic tissue sampling methods. Methods An electronic endoscopic report database was searched for patients referred for evaluation of incidentally found gastric antral subepithelial lesions. Tissue sampling technique, pathology, and complications were recorded. Results Removal of suspected pancreatic rests with EBLSP was successful in all 21 cases without complications. Nineteen of 21 (90%) who underwent EBLSP had a histological diagnosis of heterotopic pancreas compared with 5 of 14 (36%) who underwent tissue sampling with biopsy and/or snare (P = 0.001). The endoscopic characteristics of the histology proven pancreatic rests were an antral subepithelial mass with central umbilication measuring 6–10 mm in diameter and located 2–6 cm from the pylorus in the 3–7 o’clock position. Conclusions Endoscopic band ligation snare polypectomy resection of gastric antral lesions suspected to be pancreatic rests had a diagnostic yield superior to standard biopsy forceps and snare polypectomy techniques. However, because all pathologically confirmed pancreatic rests had typical endoscopic appearances of pancreatic rests, it may not be necessary to obtain histologic diagnosis for every suspected gastric antral heterotopic pancreas.
