摘要
目的:综合评价CT在胃癌诊断中的作用。材料与方法:1989年1月~1994年4月,共269例胃异常病变患者接受了CT检查,肿瘤性病变者238例,其中胃癌198例,均属中晚期,78例为回顾性分析,120例为前瞻性研究,162例经手术和病理证实。CT机为GECT/9800Quick,检查前10分钟肌注654-220mg,口服水1000ml作为对比剂,患者体位根据病灶部位而定。结果:采用新的CT检查技术,病变检出率100%,定性准确率90%,采用Borrmann分型法CT分型准确性94.3%,对75例胃癌进行了前瞻性术前分期研究,采用统一的TNM分期,并与手术病理严格对照,胃癌CT分期总的准确性85.33%,术前切除可能性估价的准确性为92%。结论:采用新的CT检查技术,利用CT独特的显示胃腔内面,及胃壁本身腔外改变的优势,可进行胃癌的CT诊断,分型,分期和术前估价。
Objective: To evaluation the role of CT in the diagnosis of gastric carcinoma.Materials and Methods:Two hundred and sixty nine patients with gastric lesions did CT examination, including gastric tumors of 238 cases of which 198 patients with advanced gastric carcinoma. 78 and 120 cases with gastric carcinoma were retrospectively and prospectively studied. All cases were confirmed either by surgiopathology (n=162) or by only endoscopic biopsy (n=36). The scans were obtained with a GE CT/9800 qiuck scanner. Intramuscular injection of hypotonic agent (654-2 20mg) was done ten minutes before the examination and the patients were all asked to drink 1000ml water as oral contrast medium.Results:CT accuracy of determining the nature of the lesion reached to 90%, CT morphologic classfication of gastric carcinoma (Borrmann system) corresponded with pathologic finding in 94.3% of cases. CT versus surgical staging of gastric carcinoma and preoperative assessment of surgical resectability, CT correctly staged 64 of 75 cases with gastric carcinoma (85.33%). The accuracy of CT preoperative evaluation for surgical resectability was 92%.Conclusion: Using new CT technique, CT is a reliable methods for diagnosing, staging and classificating of gastric carcinoma.
