The authors review the role of endoscopic ultrasound (EUS) in the staging of cancers throughout the gastrointestinal tract. EUS offers an advantage over cross-sectional imaging in locoregional tumor staging but is less sensitive in identifying distant metastasis. The addition of FNA increases diagnostic accuracy and provides a tissue diagnosis. EUS combined with cross-sectional imaging is important in accurately staging GI tumors and thereby reducing unnecessary procedures and health care costs.
作者回顾了内镜超声（EUS）在胃肠道癌症分期中的作用。EUS 在局部肿瘤分期方面优于横断面成像，但在识别远处转移方面的敏感性较低。FNA 的加入提高了诊断准确性，并提供了组织诊断。EUS 结合横断面成像对于准确分期胃肠道肿瘤非常重要，从而减少了不必要的检查和医疗费用。
