초록
내시경 초음파검사는 식도벽의 조직학적 층구조를 가장 유사하게 반영하는 검사법으로 식도 병변의 진단과 치료전략에 필수검사이다. 표재성 식도암에서 고주파 미세탐촉자를 이용한 EUS는 내시경 절제 같은 국소치료가 가능한 환자들을 선별하는 데 중요한 역할을 한다.
Endoscopic ultrasound in the diagnosis of esophageal carcinoma is an indispensable procedure, not only to discuss the preoperative staging of the lesion, but also to evaluate the therapeutic effect of chemo-radiation therapy. The recent increase in the incidence of superficial esophageal cancer and promising developments in potentially curative endoscopic therapies have placed EUS to a central position in decision making. Recent data have called into question the staging accuracy of EUS to distinguish mucosal from submucosal lesions, particularly in patients with early disease. In those cases, diagnostic endoscopic resection may be useful for staging and curative in superficial lesions. Nonetheless, EUS has been regarded as the most accurate staging tool and should be performed to identify potential candidates for endoscopic resection.
