Ligation-assisted endoscopic mucosal resection of gastric heterotopic pancreas

Figure 1 Endoscopic view of heterotopic pancreas of the stomach showing a medium-sized subepithelial nodule with central umbilication and normal overlying mucosa. The pylorus is visible distally.

Figure 2 Radial EUS images. A pancreatic rest showing an 8 mm × 6 mm hypoechoic subepithelial mass appearing to involve the mucosa (A) and submucosa (B). The tumor was confirmed as submucosal in origin after resection without involvement of the mucosa.

Figure 3 Ligation-assisted EMR of pancreatic rest. The banding device was positioned over the target lesion (A), suction was applied and a band was deployed. The lesion was then resected using electrocautery snare. Residual ulcer is shown (B).

Figure 5 Endoscopic view of heterotopic pancreas of the stomach showing a medium-sized subepithelial nodule with central umbilication and normal overlying mucosa. The pylorus is visible distally.

Figure 6 Radial EUS images of a pancreatic rest showing a 9 mm × 7 mm hypoechoic subepithelial mass appearing to involve the deep mucosa and submucosa. The tumor was confirmed as submucosal in origin after resection without involvement of the mucosa.
