本文报告应用水充盈低张胃CT动态扫描对胃癌病人进行术前疾病分期。以50例正常人测定数据为标准,结果发现75例胃癌病人均测得肿块。CT测得肿块的直径最小2cm,最大15cm,平均6.78±2.63cm。65例进行手术治疗的病人,术中发现淋巴结肿大45例,共取得121枚淋巴结,其中CT测得84枚。直径<0.6cm的淋巴结CT检出率为23.81%,而直径>1.0cm者CT检出率达到91.67%,其中病理诊断为癌转移者59枚。CT对邻近器官侵犯的检出率较高,各器官受累的判断准确率为97.33%。CT分期与病理分期的吻合率为85.33%。
This article reports the use of water filling and low stomach CT dynamic scan for preoperative disease staging of gastric cancer patients. Based on the data of 50 normal persons, the results showed that 75 cases of gastric cancer patients were measured in the mass. The diameter of the tumor measured by CT was the smallest 2cm, the largest 15cm, and the average 6.78±2.63cm. In 65 patients who underwent surgical treatment, 45 lymph nodes were found during the operation. A total of 121 lymph nodes were obtained, of which 84 were detected by CT. The detection rate of lymph nodes with a diameter of less than 0.6 cm was 23.81%, while the detection rate of CT with a diameter of 1.0 cm was 91.67%. Among them, 59 were pathologically diagnosed as cancer metastases. The detection rate of CT involvement in adjacent organs was high, and the accuracy of judgment of involvement of organs was 97.33%. The coincidence rate of CT staging and pathological staging was 85.33%.
