The aim of this study was to assess the depth of invasion of early esophageal carcinoma (EEC) by means of double-contrast esophagography.
The radiological findings of 46 EECs were retrospectively analyzed for the following factors that might be related to the depth of invasion: in depressed lesions (n = 30): maximum size, surface appearance, sharpness of contour, and wall rigidity; and in elevated lesions (n = 16): maximum size, height, shape, and wall rigidity. All lesions were surgically or endoscopically resected and the radiological findings were compared with the histological appearance.
In depressed lesions, the size of the surface granules correlated very strongly with the depth of invasion (rs = 0.8147). In both depressed and elevated lesions, wall rigidity correlated strongly with the depth of invasion (rs = 0.7540 and rs = 0.6702 respectively). In depressed lesions, sharpness of contour also correlated strongly with the depth of invasion (rs = 0.6731). The other factors did not correlate with the depth of invasion.
Double-contrast esophagography could provide useful information for assessing the depth of invasion of EECs.
本研究旨在通过双重对比食管造影术评估早期食管癌（EEC）的浸润深度。
回顾性分析46例EEC的放射学表现，以寻找可能与浸润深度相关的以下因素：凹陷性病变（n = 30）：最大尺寸、表面外观、轮廓清晰度和壁僵硬程度；隆起性病变（n = 16）：最大尺寸、高度、形状和壁僵硬程度。所有病变均经手术或内镜切除，并将放射学表现与组织学表现进行比较。
在凹陷性病变中，表面颗粒大小与浸润深度的相关性非常强（rs = 0.8147）。在凹陷性和隆起性病变中，壁僵硬程度均与浸润深度密切相关（分别为rs = 0.7540和rs = 0.6702）。在凹陷性病变中，轮廓清晰度也与浸润深度密切相关（rs = 0.6731）。其他因素与浸润深度无关。
双重对比食管造影术可为评估EEC的浸润深度提供有用信息。
