目的 :探讨胃癌分期中超声检查的诊断价值。方法 :对 42例胃癌患者进行术前超声诊断 ,并与术后病理检查进行对比分析。结果 :B超胃癌分期诊断与术后病理符合率为81 % ,其中 T1N0 M0 ～ T3- 4N1M0 各期判断符合率分别为 5 0 % ,80 % ,85 % ,1 0 0 %。早期癌与进展期癌的胃壁厚度差异均有极显著性 ,T1N0 M0 与 T2 N0 M0 之间差异无显著性 ,T3N0 M0 与T3- 4N1M0 差异有显著性。结论 :超声对胃癌术前分期提供了重要依据 ,对临床选择治疗方案和手术切除范围有重要价值
Objective: To investigate the diagnostic value of ultrasonography in gastric cancer staging. Methods: Forty-two patients with gastric cancer underwent preoperative ultrasonography and compared with postoperative pathological examination. Results: The coincidence rate of diagnosis and postoperative pathologic diagnosis of B-type gastric cancer was 81%. The coincidence rates of T1N0 M0-T3-4N1M0 were 50%, 80%, 85% and 100% respectively. There were significant differences in the thickness of gastric wall between early and advanced cancers. There was no significant difference between T1N0 M0 and T2 N0 M0. There was significant difference between T3N0 M0 and T3-4N1M0. Conclusion: Ultrasonography provides an important basis for the preoperative staging of gastric cancer, and has important value for clinical treatment options and surgical resection scope
