胃窗超声造影与常规超声检查在胃癌术前T分期中的应用比较

摘要

Objective To study effectiveness of application of the gastric window CEUS (Contrast-Enhanced Ultrasound) and conventional ultrasonography in preoperative T-staging of gastric carcinomas. Methods Gastric window CEUS images and conventional ultrasonographies of 70 gastric carcinoma patients who were treated from January to December 2013 in the hospital were retrospectively analyzed and compared with the postoperative pathological results. Results The detection rate of gastric window CEUS was 100%(70/70) versus conventional ultrasonography’s 58.6%(41/70), which was of statistically signiifcant difference (P<0.05). The accurate rate of gastric window CEUS in stage T1, T2, T3, T4 gastric carcinomas was 88.9%, 85.7%, 83.3%, 90.2% respectively in contrast with the conventional ultrasonography’s 0, 0, 66.7%, 75.6%. Statistical significance existed between the accuracy rate of two examination methods (P<0.05) in diagnosis of stage T1, T2, T3, T4 gastric carcinomas. Conclusion Gastric window CEUS demonstrated its advantages over the conventional ultrasonography in detection of gastric lesions and preoperative T-staging of gastric carcinomas.%目的：探讨胃窗超声造影与常规超声检查在胃癌术前T分期中的应用价值。方法回顾性分析2013年1月～12月我院收治的70例胃癌患者的胃窗超声造影与常规超声检查资料，并与术后病理结果进行对比。结果胃窗超声造影对胃癌病灶的检出率为100%（70/70），常规超声检查对胃癌病灶的检出率为58.6%（41/70），两者检出率比较差异有统计学意义（P＜0.05）。胃窗超声造影对胃癌T1、T2、T3、T4期的分期准确率分别为88.9%、85.7%、83.3%、90.2%，常规超声检查对胃癌T1、T2、T3、T4期的分期准确率分别为0、0、66.7%、75.6%。两种检查方法对T1、T2、T3、T4各期的分期准确率比较，差异均有统计学意义（P＜0.05）。结论与常规超声检查比较，胃窗超声造影对胃癌病灶的检出率更高，对胃癌的术前T分期具有较高的应用价值。
