经腹超声对胃癌的诊断价值及术前分期

THE DIAGNOSTIC VALUE OF TRANS-ABDOMINAL VLTR ASONOGRAPHY AND PREOPERATIVE STAGING IN GASTRIC CANCER

目的:探讨经腹超声显像对胃癌的诊断价值及对胃癌术前分期的诊断价值。方法:42例胃癌患者口服"胃窗-85"声学对比剂500-600m l进行经腹超声检查,并依照国际TNM分期法对胃癌进行术前分期,所得结果与术后与病理结果对照。结果:经腹超声检查对胃癌T分期的诊断符合率为71.4%(30/42),其中T1:50%(2/4),T2:62.5%(5/8),T3:75%(15/20),T4:80%(8/10);对胃癌N分期的诊断符合率为80%(16/20),其中N1:77%(7/9),N2:81.8%(9/11);对胃癌M分期的诊断符合率为60%(6/10)。结论:经腹超声能较好地显示胃壁层次及受浸润的情况,对胃癌的术前分期提供重要的客观依据。

Objective：The article was made to explore and discuss the diagnostic value of trans - abdominal ultrasonography and preoperative staging in gastric cancer. Methods：42 cases of gastric cancer, who had taken 500 - 600mal oral ultrasonic contrast agent, were examined by using trans - abdominal ultrasonography ; preoperative staging in gastric cancer was made based on international TNM staging; the comparison was made between pathological results and postoperative ones. Results： In terms of T stage, the accuracy rate of gastric cancer diagnosis by using trans -abdominal ultrasonography was 71.4% （30/42）, of which T1 accounted for 50% （2/4）, T2 62.5% （5/8）, T3 75% （15/20）, T4 80% （8/10） respectively. In terms of N stage, the accuracy rate was 80% （ 16/20）, of which N1 made up 77% （7/9）, N2 81.8% （9/11 ）. In terms of M stage, the accuracy rate was 60% （6/10）. Conclusion：The information of the layers of the gastric wall and its infiltration is displayed fairly well by trans - abdominal ultrasonography, and important objective evidences is provided in terms of preoperative staging in gastric cancer.
