EUS is the most accurate tool for local staging of rectal carcinoma. In addition to providing accurate T- and N-stages, EUS allows assessment of the internal and external anal sphincters. Accurate endosonographic staging directs the optimal method of management of rectal carcinoma, type of resection, and candidacy for neoadjuvant therapy. EMR may be applied to large rectal adenomas as an alternative to surgical resection in selected patients. EUS is important in discriminating lesions suitable for EMR.
超声内镜是直肠癌局部分期最准确的工具。除了提供准确的T分期和N分期外，超声内镜还可用于评估肛门内、外括约肌。准确的内镜超声分期可指导直肠癌的最佳治疗方法、切除类型以及新辅助治疗的适应证。对于部分患者，内镜下黏膜切除术（EMR）可作为手术切除的替代方法应用于较大的直肠腺瘤。超声内镜在鉴别适合EMR的病变方面很重要。
