EUS has become a substantial diagnostic and therapeutic modality for digestive tract conditions. The extent of endosonographic assessment is wide, and, among others, it allows for the evaluation of liver anatomy and related pathologies. Moreover, EUS assessment has proved more accurate in detecting small focal liver lesions missed by standard imaging examinations such as computed tomography or magnetic resonance. Endosonographically, various liver segments can be visualized by transgastric and transduodenal scanning following anatomical landmarks, thus providing arranged systematic examination. In addition, knowledge considering the correct position during examination is crucial for EUS-guided procedures such as hepaticogastrostomy, ablation of tumors, and measurement of portal pressure gradient. The evolution of EUS-guided intervention has contributed to the increasing importance of understanding the hepatic segmental anatomy during the EUS examination.
超声内镜已成为诊断和治疗消化道疾病的重要手段。超声内镜检查的范围广泛，其中包括对肝脏解剖结构及相关病变的评估。此外，在检测计算机断层扫描或磁共振成像等标准影像学检查遗漏的小局灶性肝脏病变方面，超声内镜评估已被证明更为准确。在超声内镜下，通过经胃和经十二指肠扫描，沿解剖标志可显示肝脏各段，从而进行有序的系统检查。此外，对于超声内镜引导下的操作，如肝胃吻合术、肿瘤消融和门静脉压力梯度测量，了解检查过程中的正确位置至关重要。超声内镜引导下干预技术的发展，使得在超声内镜检查过程中理解肝段解剖结构的重要性日益增加。
