摘要
目的 探讨B型超声显像对胃良、恶性溃疡鉴别诊断的声像图标准。方法 采用高频B型超声显像观察并测量282例胃良、恶性溃疡的大小,溃疡周围胃壁厚度、规则程度、胃壁内侧第2层厚度、蠕动情况及增厚胃壁与正常胃壁分界情况。并进行统计学处理,与病理结果对照。结果 117例良性溃疡和165例恶性溃疡直径分别为14.86±10.42mm和18.25±11.32mm,周围胃壁厚度分别为13.25±5.79mm和17.92±8.37mm,胃壁内侧第2层厚度分别为1.95±0.65mm和4.36±1.28mm。经t检验,P值分别为P(0.05,P<0.05,P<0.01。以溃疡周围胃壁层次显示清楚、规则,内侧第2层厚度<3mm作为良性溃疡鉴别诊断标准,其敏感性达98.29%,特异性达96.97%。结论 高频超声显像在胃良恶性溃疡鉴别诊断中具有较大的实用价值。
Objective To evaluae the different features of ultrasonography of benign and malignant gastric ulcers. Methods High frequency ultasound had been measured 282 cases of bening and malignant gastric ulcers sizes, ulcers surrounding walls thickness, regularity , the second layers thickness of inner gastric wall, states of peristalsis and the thickened boundaries and normal gastric walls. Those datura were treatded with statistical process and all the findings were compared with pathologies. Results The diameters of 117 cases benings and 165 cases gastric surrounding gastric walls were 14.86 ±16.42mm and 18.25 ± 11.32mm separately, the thickness of second layers of inner gastric walls were 13.25 ± 5.97mm and 17. 92 ± 8.37mm, the thickness of second layers of inner gastric walls were 1.95 ± 0.65mm and 4.36 ± 1.28mm. the p values are P < 0/05, p < 0.05, and P< 0.01 separately. Conclusion The layers of benign gastric wall are revealed clearly and regularly. the second layer of inner gastric wall is < 3mm,which the sensitivity is 98.29% and the specificity is 96.97% .Use the high frequency of ultrasonograph can distingish the benign and malignant gastric ulcer,and has great diagnosis value.
