目的研究胃镜结合MSCT对胃癌术前分期诊断的准确性。方法收集200例胃癌患者术前行胃镜和MSCT的检查及200例胃癌患者术前行7mm层厚的螺旋CT的检查资料,进行术前分期,并与术后病理结果对照,比较两者对胃癌术前分期的准确性。结果胃镜结合MSCT与7mm层厚CT的T分期的结果符合率分别为87%和52%,N分期的结果符合率分别为85%和36%,两者均差异显著,具有统计学意义,胃镜结合MSCT的诊断率符合率相对较高。结论胃镜结合MSCT能够更好地指导临床选择恰当的手术切除范围、手术方式和制订综合治疗方案,为患者赢得更高的生活质量和更长的生存时间。
Objective To study the accuracy of gastroscopy combined with MSCT for the preoperative staging of gastric cancer. Methods Preoperative gastroscopy and MSCT examination of 200 cases of gastric cancer and 200 cases of gastric cancer were performed preoperative 7mm layer thickness spiral CT examination data, preoperative staging, and postoperative pathological results were compared, the two of gastric cancer Preoperative staging accuracy. Results The coincidence rates of T staging by gastroscopy with MSCT and 7 mm thick CT were 87% and 52%, respectively. The coincidence rates of N staging were 85% and 36% respectively, which were significantly different between the two groups The combined rate of MSCT diagnosis is relatively high. Conclusion Gastroscope combined with MSCT can better guide the clinical choice of appropriate surgical resection, surgical approach and the development of comprehensive treatment programs for patients to win higher quality of life and longer survival time.
