The Role of Endoscopic Ultrasonography in the Differential Diagnosis of Polypoid Lesions of the Gallbladder: an Update

Although most gallbladder (GB) polyps are benign, some early carcinomas of the GB share same appearance as benign polyps. Currently, larger than 1 cm should be surgically removed because increased risk malignancy. Distinguishing between nonneoplastic and neoplastic lesions is a major diagnostic dilemma, therapeutic options for these remain controversial. Endoscopic ultrasonography (EUS) considered to superior conventional US imaging since EUS can provide high-resolution images small with higher ultrasound frequencies. However, differential diagnosis remains difficult, especially Thus, various methods using have been introduced overcome difficulty non-neoplastic Contrast-enhanced harmonic useful observing microvascular patterns additional enhancement This requires post-recording analysis due short time. Real-time color Doppler-EUS provides Doppler flow vessels without time limit. Keywords: Gallbladder, polyp; 중심 단어: ë‹´ë‚­ìš©ì¢ ; 내시경 초음파
