摘要
目的 提高食管胃结合部早期癌的X线检出率。资料与方法 应用数字 10 0 0mA胃肠机检查食管胃结合部早期癌 5 8例 ,强调检查体位 ,并按病理分型、局部分区、侵犯粘膜的深浅分别探索检出率。结果 5 8例食管胃结合部早期癌 ,检出 5 1例 ,检出率为 88% ,其中Ⅰ、Ⅲ型检出率为 10 0 % ,Ⅱa和Ⅱc型分别为 89.4%和 81.3%。贲门处检出率为 80 % ,胃小弯近贲处为 94% ,胃底近贲门处为 5 0 %。病变浸润粘膜层检出率为 75 % ,粘膜下层为94%。最小能检出 0 .3cm× 0 .5cm大小病变。结论 数字胃肠机及认真应用体位检查食管胃结合部早期癌显示率很高。
Objective To improve X ray detecting rate of the early cancer at the esophagogastric junction.Materials and Methods GI series examination was performed in 58 patients with early cancer of esophagogastric junction on a 1000mA digital gastrointestinal unit. During the examination, great attention was paid to the patient's position so that the lesion could be best displayed. The lesions were divided according to the pathology, site and the infiltrated depth of the mucosa, from which the detecting rate was calculated respectively.Results Of 58 cases, the lesion was detected by radiography in 51 (88%), of which the detecting rate was 100% for Ⅰ and Ⅲ type, 89.5% for Ⅱa type and 81.3% for Ⅱc type. The detecting rate for lesions located at cardiac region, at lesser curve nearby cardiac region and at gastric fundus was 80%, 94% and 50%, respectively. The detection of mucosal and submucosal invasion was 75% and 75%, respectively. The smallest detectable lesion was 0.3 cm×0.5 cm.Conclusion The detection of early cancer at esophagogastric junction can be greatly improved when digital GI unit is used and suitable patient's position is adopted.
