摘　　要：The gallbladder(GB)is a susceptible organ,prone to various pathologies that can be identified using different imaging techniques.Transabdominal ultrasound(TUS)is typically the initial diagnostic method due to its numerous well-established advantages.However,in cases of uncertainty or when a definitive diagnosis cannot be established,computed tomography(CT)or magnetic resonance imaging may be employed to provide more detailed information.Nevertheless,CT scans may sometimes offer inadequate spatial resolution,which can limit the differentiation of GB lesions,particularly when smaller yet clinically relevant abnormalities are involved.Conversely,endoscopic ultrasound(EUS)provides higher frequency compared to TUS,superior spatial resolution,and the option for contrast-enhanced harmonic imaging,enabling a more comprehensive examination.Thus,EUS can serve as a supplementary tool when conventional imaging methods are insufficient.This review will describe the standard EUS examination of the GB,focusing on its endosonographic characteristics in various GB path-ologies.
