다국어 초록 (Multilingual Abstract)

A lymphangionma is a rare benign tumor occuring in the gastrointestinal tract, which is composed of lymphatic vessels of various size. A sharply demarcated smooth, soft, cystic submucosal tumor which is easily compressible and covered with normal mucosa is a characteristic ally an endoscopic feature. This lesion is considered to be a benign lesion, which does not need to be treated, but in cases that involve risk of any complications or symptoms, the lesion needs to be removed. Servral endoscopic treatment methods for a symptomatic lymphangioma have been introduced, but accompanying risk of complications, such as bleeding or perforation were reported. As complete removal of a lymphangioma is impossible due to its broad base, a newly developed unroofing method is presented to be effective and safe for resection of a large lymphan-gioma. Recently, 2 cases were experienced involving a lymphangioma in the large intestine, which was removed successfully by colonscopic unroofing therapy.
