Endosonography (EUS) is a relative newcomer to the field of gastrointestinal endoscopy. Nevertheless, two prospective studies with similar results have shown that EUS leads to a change in management in roughly two-thirds of patients in whom it is performed, with many of these changes being to less invasive or less expensive management. Preliminary investigations on the use of catheter probes for performing EUS have shown similar effects. Specific investigations on the effect of EUS on the outcomes of patients with submucosal tumors, esophageal cancers, pancreatic cancers, and rectal cancers need to be performed. Selective studies have demonstrated EUS to be cost-effective for the management of submucosal tumors and ampullary tumors. The complication rate of EUS appears to be comparable to that of upper endoscopy. There is little or no information regarding training in EUS, practice variation, or affect of EUS on quality of life.
内镜超声检查（EUS）在胃肠内镜领域是一个相对较新的技术。尽管如此，两项结果相似的前瞻性研究表明，EUS在大约三分之二接受该检查的患者中导致了治疗方案的改变，其中许多改变是采用侵入性较小或费用较低的治疗方法。关于使用导管探头进行EUS的初步研究也显示了类似的效果。需要对EUS对黏膜下肿瘤、食管癌、胰腺癌和直肠癌患者预后的影响进行具体研究。一些选择性研究表明，EUS在管理黏膜下肿瘤和壶腹肿瘤方面具有成本效益。EUS的并发症发生率似乎与上消化道内镜检查相当。关于EUS培训、实践差异或EUS对生活质量影响的信息很少或几乎没有。
