目的：探讨超声内镜（EUS）联合多层螺旋CT扫描（MSCT）检查对结直肠癌（CRC）术前TNM分期判断的准确性。方法连续选取在我院外科手术治疗并符合入组条件的CRC患者共39例，以术后病理TNM分期作为金标准，评价EUS、MSCT及两者联合对CRC患者术前TNM分期的准确性。结果本组患者EUS对CRC的T分期判断准确率分别为75.0%～83.3%，N分期为50.0%～80.0%；MSCT对CRCR的N分期判断准确率为60.0%～83.3%，EUS、MSCT对于N0、N1的判断的准确率接近，而对于N2的判断，两者联合较EUS优势明显（91.7%vs 50.0%，P<0.05）。结论 EUS对CRC术前T分期及N0、N1分期具有较高的临床应用价值；而MSCT对N2、M分期的准确性较高，两者联合检查，可获得更精准的术前TNM分期。

Objective To investigate the colorectal cancer (CRC) preoperative TNM staging accuracy by endoscopic ultrasonography (EUS) combined with multi-slice helical CT scan (MSCT) examination. Methods Thirty nine consecutive CRC patients who underwent surgical treatment in our hospital and met the inclusion criteria were selected. Pathological TNM staging served as the gold standard to evaluate the preop-erative TNM staging accuracy of EUS, MSCT and their combination. Results The accuracy of EUS for T staging was 75.0%~83.3%, N staging 50.0%~80.0%; the accuracy of MSCT for N staging was 60.0%~83.3%. The diagnostic accuracy of EUS, MSCT for N0, N1 staging was very close;and for N2, EUS combined with MSCT was superior to EUS only (91.7%vs 50.0%, P<0.05). Conclusion In preoperative CRC, EUS for T, N0, N1 staging has higher clinical value, while MSCT for N2, M staging has higher accuracy, and the com-bined inspections can get a more accurate preoperative TNM staging.
