本文报告30例早期食管癌,均经手术病理证实,对其低张双对比造影的表现及病理基础进行了讨论.认为将早期食管癌分为浅表型(11例)、凹陷型(3例)和隆起型(16例)。较为简单实用.本组 X 线诊断早期食管癌与病理组织学检查的符合率为90%.文中并对食管低张双对比造影检查的技术要求进行了讨论. This article reports 30 cases of early esophageal cancer, were confirmed by pathology, the performance and pathological basis of its low-tensor double contrast angiography were discussed. The early esophageal cancer was considered to be superficial (11 cases), depression type (3 cases) ) and uplift type (16 cases). It is simple and practical. The coincidence rate of X-ray diagnosis of early esophageal cancer and histopathological examination in this group is 90%. The technical requirements for double-contrast angiography of esophageal hypotonia are discussed.
