1 资料 我院自1988年1月以来,应用B型超声诊断胃癌41例,男28例、女13例,平均年龄58.7岁,其中60岁以上20例。胃癌超声特征:(1)肿块呈“假肾征”样声象图,饮水后证实与胃相关。(2)胃壁层次破坏及非均匀性增厚,厚度>5mm。(3)贲门范围扩大,直径>20mm,靶心偏移。(4)胃液潴留。肿瘤部位与超声定位符合情况(见附表)。发现癌灶转移13例占31.7％。其中转移性肝癌4例,肝及脾静脉内转移1例,肝及腹腔淋巴结转移1例,肝及腹腔、主动脉周围淋巴结及门静脉主干转移1例、胰头癌1例、腹腔淋巴结转移3例,主动脉周围淋巴结转移2例,另合并腹水2例。
1 data from January 1988 in our hospital, the use of B-mode ultrasound diagnosis of 41 cases of gastric cancer, 28 males and 13 females, the average age of 58.7 years, of which more than 60 years of age in 20 cases. Ultrasonic Features of Gastric Cancer: (1) The tumor showed a “pseudo-renal sign” like sound image. After drinking water, it was confirmed to be related to the stomach. (2) Destruction of the stomach wall and thickening of inhomogeneity, thickness> 5mm. (3) Enlargement of cardia range, diameter >20mm, bull’s eye shift. (4) gastric fluid retention. The location of the tumor was consistent with ultrasound positioning (see attached table). 13 cases of cancer metastasis were found in 31 cases. There were 4 cases of metastatic liver cancer, 1 case of liver and splenic vein metastasis, 1 case of liver and abdominal lymph node metastasis, 1 case of liver and abdominal cavity, aortic lymph node and portal vein trunk, 1 case of pancreatic head cancer, and 3 cases of abdominal lymph node metastasis. There were 2 cases of aortic lymph node metastasis and 2 cases of ascites.
