摘要

目的：探讨胃窗超声造影（OCU）、多层螺旋CT（MSCT）及两者联合诊断胃癌的价值。方法：60例经胃镜活检和术后证实的胃癌患者术前均行OCU、MSCT检查，将TNM分期情况与术后病理进行对照分析。结果：T分期总准确率OCU为80.00%（48/60）、MSCT为71.67%（43/60）、两者联合为88.33%（53/60），3者对胃癌T分期的诊断差异无统计学意义（P>0.05），但对于胃癌的T1、T2分期OCU（62.5%、77.8%）较MSCT（37.5%、55.6%）准确率高。N分期总准确率OCU为61.67%（37/60）、MSCT为73.33%（44/60）、两者联合为85.00%（51/60），3者对胃癌N分期的诊断差异有统计学意义（P<0.05），其中N3分期准确率OCU为35.00%（7/20）、MSCT为75.00%（15/20），两者诊断差异有统计学意义（P<0.05）。M分期单用两种检查及联合检查无显著差异。结论：OCU与MSCT联合诊断，可提高胃癌术前TNM分期，对拟定手术方式或治疗方案具有重要的参考价值。

Abstract

Objective: To study the value of using oral contrast ultrasonography(OCU), multislice computed tomography(MSCT), and the combination of the two methods in diagnosing gastric cancer. Methods: Sixty cases of gastric cancer confirmed by endoscopic biopsies and surgeries were examined by OCU and MSCT before surgery. Imaging TNM staging and postoperative pathology were compared. Results: For the total accuracy of T staging, OCU was 80.00%(48/60), MSCT was 71.67%(43/60), and their combination was 88.33%(53/60). The difference of these three methods for T staging was not statistically significant(P>0.05). However, for T1 and T2 staging, OCU(62.50%, 77.78%) was more accurate than MSCT(37.50%, 55.56%). For the total accuracy of N staging, OCU was 61.67%(37/60), MSCT was 73.33%(44/60), and their combination was 85.00%(51/60). The difference of these three methods for N staging was statistically significant(P<0.05). For the accuracy of N3 staging, OCU was 35.00%(7/20), MSCT was 75.00%(15/20), and their difference was statistically significant(P<0.05). There was no significant difference among OCU, MSCT and their combination for M staging. Conclusions: The combination of OCU and MSCT can improve the accuracy of TNM staging for gastric cancer, and have important reference value for designing surgery or treatment programs.
