Endoscopic ultrasound (EUS) is a useful diagnostic tool for evaluation of esophagogastric varices and guidance of endoscopic therapy. EUS can visualize not only collateral veins around the esophagus but also perforating veins that connect esophageal varices with collateral veins. They are associated with high risk of bleeding and early recurrence after initial variceal eradication. Isolated gastric varices can be easily diagnosed using EUS that mimic thickened gastric folds or subepithelial tumors. EUS-guided endoscopic therapy is a challenging field of variceal bleeding. It has a potential role for assistance of interventions and evaluation of treatment outcome.
内镜超声(EUS)是评估食管胃静脉曲张及指导内镜治疗的一种有用的诊断工具。EUS不仅可以观察食管周围的侧支静脉,还能观察连接食管静脉曲张与侧支静脉的穿支静脉。它们与初次静脉曲张根除术后的高出血风险及早期复发有关。孤立性胃静脉曲张使用EUS很容易诊断,其表现类似增厚的胃皱襞或上皮下肿瘤。EUS引导下的内镜治疗是静脉曲张出血治疗中一个具有挑战性的领域。它在辅助干预措施及评估治疗效果方面具有潜在作用。
