Endoscopic polypectomy was successfully performed to 6 cases of esophageal tumor, using loop snear with high frequency electric current. Results of histologic examination of these tumors were esophageal polyps (2), inflammatory granuloma (I), epitherial hyperplasia (I) and esophageal leiomyomas (2). There was no complication. No patients complaimed of pain or discomfort. They discharged on third day after endoscopic polypectomy and followed at out-patient clinic. Esophageal ulcers after polypectomy were covered by regenerated esophageal epitherial cells untill 10 days and completely healed on 30 days after polypectomy. We usually apply endoscopic polypectomy for intra-luminal benign esophageal tumors. Leiomyomas of the esophgus are mostly intramural tumors but some of them are orignated from muscularis mucosa and protrude into the lumen forming intraluminal tumors. These superfiscial leiomyomas can be removed by endoscopic polypectomy. These 6 polypectomy cases were performed among 5000 esophagoscopy in 5 years in our institute.
