内镜超声与仿真CT检查在胃癌分期诊断中的对比研究

The comparison study between endoscopic ultrasonography and Virtual CT in the diagnosis and staging of gastric cancer

目的评价内镜超声和仿真CT检查对胃癌患者术前分期的准确性。方法24例胃癌患者，术前行内镜超声及仿真CT检查，并与术后病理对照，以评价内镜超声与仿真CT检查在胃癌分期中的诊断价值。结果内镜超声对胃癌T、N、M分期的敏感性是：87．5％（21／24）；79.2％（19／24）；57．1％（4／7）。仿真CT对T、N、M分期的敏感性是：79．2％（19／24）；70．8％（17／24）；100.0％（7／7）。结论内镜超声检查对胃癌侵犯的深度和局部淋巴结转移的诊断有更为显著的诊断价值，仿真CT对于远处转移的判断是有利的补充手段。

Objective To assess the clinical significance of endoscopic uhrasonography（EUS） and CT virtual in the diagnosis and preoperative staging of gastric cancer. Methods Twenty-four gastric cancer patients were scanned on CT-Virtual and endoscopic uhrasonogrphy, operative findings and pathological diagnosis were correlated with that of spiral CT and endoscopic uhrasongrphy findings. Results The sensitivity of EUS in T,N and M stage were 87. 5% （21/24） ;79. 2% （19/24） and 57. 1% （4/7） , The sensitivity of CT-virtual in T,N and M stage were 79. 2% （ 19/24）, 70. 8% （17/24） and 100.0% （7/7）. Conclusion EUS shows the prominent advantage in preoperative evaluation of the staging of gastric cancer especially in the diagnosis of the depth of tumor invasion and local lymph node metastasis, CT-virtual is an efficient complement in diagnosis of gastric cancer.
