低张服水螺旋CT扫描对胃癌的TNM分期诊断价值

Spiral CT Scanning Using Hypotonic Agent and Taking Water as Contrast Media: Its Value in TNM Staging of Gastric Carcinoma

目的 探讨胃癌螺旋CT的TNM分期诊断价值。资料与方法 5 0例经胃镜证实的胃癌患者进行低张服水螺旋CT扫描。根据胃癌的部位、大小、范围、浸润程度、周围淋巴结及脏器转移情况进行TNM分期 ,并与术后病理分期对照。结果 低张服水螺旋CT对胃癌TNM分期准确性为 76 %,其中T分期准确性为 78%,N分期准确性为 6 2 %,M分期准确性为 96 %。结论 低张服水螺旋CT检查的TNM分期对评估胃癌的手术方案及临床治疗有较大的价值。

Objective To evaluate spiral CT scanning in TNM staging of gastric carcinoma.Materials and Methods With the use of hypotonic agent and orally taking water as contrast media, spiral CT scanning was performed in 50 patients with pathologically proved gastric cancer. TNM staging of the lesion was made based on the site, size and extent of the lesion, the local infiltration, the neighboring lymph nodes situation and the visceral metastasis. The results were compared with postoperative pathological TNM staging.Results Spiral CT scanning with hypotonic and water drinking technique showed an accuracy of 76% in making TNM staging for gastric cancer. The staging accuracy for T, N and M was 78%, 62% and 96%, respectively.Conclusion Spiral CT scanning, with the use of hypotonic agent and orally taking water as contrast media, is very helpful in TNM staging of the gastric cancer, which is of great value in planning surgical management and guiding the clinical therapy.
