HYPERPLASTIC POLYP DEVELOPING AFTER ENDOSCOPIC MUCOSAL RESECTION OF EARLY GASTRIC CANCER WAS REDUSED IN SIZE BY ERADICATION OF HELICOBACTER PYLORI

Abstract

A 59-year-old man, who was found by endoscopy to have a polypoid mass, 1.0cm in diameter at the anterior wall of the gastric angle, was admitted to our hospital for the purpose of resection. The exiced specimen obtained form endoscopic mucosal resection (EMR) revealed well differentiated adenocarcinoma. No tumorous component was detected around the cut end, suggesting a curative resection. Endoscopic examination at 3 months after EMR revealed a polyp, 0.7cm in diameter, on the scar of the first resection, which grew to 1.5cm in diameter during the next 2 years. We performed biopsy, showing hyperplastic polyp, then we tried eradication of Helicobacter Pylori. The polyp remarkably reduced in size by the eradication.
