초록
국내에서는 최근 국가암검진 프로그램으로 인하여 위내시경 검사가 보편화되어 무증상의 위용종이 발견되는 경우가 많아지고 있다. 넓은 의미의 용종이란 위장관의 내강 쪽으로 돌출된 병변을 의미하나 엄격하게는 위의 점막층에서 발생된과증식성 또는 종양성 병변으로 정의할 수 있다[1]. 위용종은상피성 용종과 비점막성 벽내용종으로 크게 분류되며(Table 1) [2] 상피성 용종에는 위저선용종(fundic gland polyp), 과증식성 용종(hyperplastic polyp), 위선종(Gastric adenoma) 등이 대표적이다. 이외에도 다양한 종류의 용종이 있지만 임상양상이나 악성화 비율 등이 각각 다르기 때문에 일률적인 치료방법을 선택하기 어렵다. 본고에서는 위용종 중에서 내시경검사 중 흔히 관찰할 수 있는 상피성 용종을 중심으로 진단및 치료에 대해 기술하고자 한다.
Abstract
A gastric polyp is defined as a proliferative or neoplastic lesion from the mucosal membrane. Rates of gastric polyp detection are increasing due to widespread use of gastrointestinal endoscopy in Korea. There are many types of gastric polyps; the most common are fundic gland, hyperplastic, and adenomatous polyps. This article reviews the clinical and histologic features of these polyps and provides recommendations for management.
