食管癌在恶性肿瘤中是常见的多发病,早期食管癌X线低张双对比造影检出率最高达到88.2%。糜烂型和乳头型早期癌易检出,斑块型次之,平坦型X线难显示。癌组织浸润黏膜X线全部检出,浸润黏膜层检出90.9%。原位癌只有33.3%的检出率,而且不能肯定诊断。
Esophageal cancer is a common and frequently occurring disease in malignant tumors. The detection rate of X-ray low contrast double contrast radiography of early esophageal cancer is up to 88.2%. Erosive and papillary early detection of cancer is easy, followed by plaque, flat X-ray difficult to show. The infiltrating mucosal layer of X-ray was detected in 90% of the cancerous tissues. In situ cancer only 33.3% of the detection rate, but not sure diagnosis.
