CT在胃癌诊治中的作用

探讨ＣＴ在胃癌诊断和治疗中的价值。对２５例术后作ＣＴ随访及５６例术前经ＣＴ检查的胃癌患者资料分别进行手术近，远期疗效和手术切除率分析。另对４７例胃癌ＣＴ所见进行术前手术切除可能性预测。分析同期１３例胃肠造影和／或内镜未能确诊的ＣＴ检验结果，对照手术以探讨ＣＴ对胃癌的诊断价值。

Application of CT in Diagnosis and Treatment of Gastric Carcinoma

To explore the role of CT in diagnosis and treatment of gastric carcinoma. Materials andMethods: Analysed 56 cases (compared the preoperative CT findings with surgery in retrospectivegroup) and 25 cases (postoperative CT scan) of gastric carcinoma evaluating the surgical resectable rateand the curative effect. According to CT findings, the tumor resectability of other 47 cases (prorpectivegroup) were predicted before operation. The CT scans of another 13 cases, with gastric lesions detected,but the differential diagnosis couldn' t be Inade by GI series and/ or endoscopy, were also discussed.Results: The surgical resectale rate of retrospective group) in operated patients at random prerperative, was 53. 57%. The five - years survival rate of patients with gastric carinoma, without the CT scanwasn't preoperatively done, was 28. 0%. In cases of prospective group, the surgical resectable rate waspromoted to 90. 91%. 11/13 cases (3 gastric carcinoma, 1 ulcer, 2 leiomyomas, 1 leiomyosarcoma, 2varices and 2 extra-mural benign tumors) were arcurately diagnosed by CT, and proved by surgery.Conclusion: Preoperative CT scan is beneficial to the diagnosis. differential diagnosis, and valuation oftumor resecboility in gastric carcinoma, therefore should be used routinely.
