探讨超声助显剂造影在胃癌临床分期中的诊断价值

Investigate the diagnostic value of ultrasound contrast agents significantly aid in the clinical stage of gastric cancer

目的：探讨胃癌采用超声助显剂造影在临床分期上的诊断价值。方法选取郑州市第九人民医院2012年6月至2014年6月收治的胃癌患者40例，采用超声助显剂造影行分期诊断，并与病理检查结果对照。结果本研究40例胃癌患者中超声检出38例，占95％。 T1诊断符合率为40％， T2为50％， T3为80％， T4为83.3％，总符合率为70％。12.5％过深判断率，17.5％过浅判断率， N0符合率为88.2％， N1为56.2％， N2为28.6％，总符合率为65％，无N3期淋巴结。腹膜转移2例，肝脏转移1例。结论胃癌采用超声助显剂造影诊断有较高的病灶检出率，对N分期、T分期判断符合率较高。虽有一定的局限性，如胃大弯癌肿、胃底部癌符合率偏低，但因其具有可重复、高分辨率、实时动态、病灶清晰显示等优点，可对实质脏器及胃腔外淋巴结的转移状况准确检出，在胃癌及分期诊断中，作用重大。

Objective To investigate the diagnostic value of gastric cancer using ultrasound contrast agents signifi -cantly aid in the clinical staging .Methods Forty patients with gastric cancer from June 2012 to June 2014 were treated with ultrasound contrast agents significantly help line staging and compared with pathological findings .Results Among the 40 ca-ses of gastric cancer patients , ultrasound detected in 38 cases, accounting for 95%.T1 diagnosis rate was 40%, T2 was 50%, T3 of 80%, T4 was 83.3%, in line with the total rate of 70%.Determine the rate of 12.5%is too deep, too shallow to judge the rate of 17.5%, N0 the rate was 88.2%, N1 was 56.2%, N2 was 28.6, the total coincidence rate was 65%, and no lymph node N3 period.More than two cases of peritoneal turn , one case of liver metastases .Conclusions Diagnosis of gastric cancer using ultrasound contrast agents help significantly with higher lesion detection rate , N stage, T stage to deermine compliance with the higher rate .Inspite of some limitations , such as the greater curvature of the stomach cancer , stomach cancer, consistent with the low rate of the bottom.However, because of a reusable, high-resolution, real-time dynamic, gastrointestinal agents can significantly help the stomach cavity lesions clearly show the advantages of parenchymal organs and the outside can accurately detect lymph node metastasis and play an important role in gastric cancer staging diagnosis .
