A 63-year-old male was refered to our hospital to examine and to treat a tumor of the stomach. An upper gastrointestinal series showed an elevated lesion more than 4cm in size at greater curvature side of gastric body. Endoscopic findings of the lesion revealed a polyp more than 4cm with a stalk of 1cm. Histological examinations of biopsy specimens of the lesion highly suggested a hyperplastic polyp. Since we considered it would be possible to treat the polyp endoscopically in spite of its huge size, endoscopic resection was performed.
In detail, two detachable snares were placed at the stalk of the polyp, an absolute ethanol of 0.2ml was injected into the stalk at a polyp side of the detachable snares and the polyp was resected using bipolar snare. Two clips were placed at the site to close the wound. Microscopic findings of a polypectomized specimen revealed hyperplastic foveolar polyp (group 2) as well as biopsy specimens.
As it has been rarely reported that such a huge hyperplastic polyp of the stomach was resected endoscopically, we think a methodology of our case such as using detachable snare and bipolar snare is unique and is worth reporting.
