Five Cases of Polypectomy using Endoscopic " O " -ring Ligation / 대한소화기내시경학회지

ABSTRACT

Endoscopic polypectomy was firstly introduced by Tsuneoka in 1969, and till now this method has been widely used for the treatment of benign and malignant polyps with the advent of technical improvement. This method is a very important modality as secondary prevention of malignancy because polyps in gastraintestinal tract are now being considered as precancerous lesion. Polypectomy with snare and electrocautery is mainly used for pedunclated polyps (eg. Yamada Class III, IV), but sessile polyps pose technical difficulty and occasionally cause serious gastrointestinal hemorrhage when resection margin adjacent polyp base. We performed polypectomy with "O"-ring used in endocopic variceal ligation (EVL) to make sessile polyp as semipedunclated form, and also to control bleeding, and then successfully remove it with conventional snare polypectomy. We report these 5 cases with the review of the literature.
