  • Fig. 1 Endoscopic treatment of gastric adenoma. (A) A 2.5 cm sized slightly depressed lesion with marginal elevation (type 0-IIc+IIa) was observed at the posterior wall of the antrum. (B) An endoscopic mucosal dissection was performed for the lesion. The final pathologic diagnosis was a 2.2×1.3 cm-sized tubular adenoma, low-grade dysplasia. The resection margin was negative for the tumor.

  • Fig. 2 Long-term follow-up of the hyperplastic polyp. Endoscopic surveillance was performed annually or biennially after the endoscopic treatment. Two years after the endoscopic treatment, a 2 cm sized hyperplastic polyp was noted on the endoscopic resection scar (A). There was no change in size 4, 6, and 8 years (B-D, respectively) after the endoscopic treatment. Nine years after the endoscopic treatment, nodularity was observed at the neck of the polyp. Thus, a biopsy was done to rule out malignancy (E). The pathologic diagnosis was Helicobacter pylori (H. pylori)-associated chronic active gastritis. (F) One year after the H. pylori eradication. The hyperemic polyp disappeared, and only its neck portion remained.
