摘要 目的 研究食管動態雙對比造影在早期食管癌診斷中的應用價值。方法 採用數字胃腸機對疑診為早期食管癌患者進行常規雙對比造影和動態雙對比造影檢查, 隨機抽取經內鏡或手術病理證實且兩種造影資料均具有的40例早期食管癌, 採用雙盲法分析, 評價其診斷的可靠性。結果 病變主要表現為區域性黏膜粗細不均、扭曲以及不規則的小龕影和充盈缺損，病變區食管壁柔軟度及舒張度減低，甚至消失。動態雙對比造影對早期食管癌區域性功能的顯示明顯優於常規雙對比造影，兩者有統計學意義的差異（χ²=4.50 Р < 0.05）。結論 動態雙對比造影在早期食管癌的診斷中具有較高價值，是一種較理想的檢查方法。 河南省人民醫院放射科雷志丹

Abstract: Objective To study the role of esophageal dynamic double
contrast radiography (DDCR ) in diagnosing early esophageal carcinoma(EEC ).
Methods The patients with clinical suspected EEC underwent conventional
double contrast radiography (CDCR ) and DDCR using digital fluoroscopic
imaging unit. The radiographic materials including CDCR and DDCR in 40 cases
with EEC proved by endoscopy or pathologic histology were analyzed by a blind
study ,and the reliability of CDCR and DDCR evaluated. Results The major
findings of EEC included the mucosa irregularity and tortuous, small
niches and filling defect, the soft and expansive extent of esophageal
wall reduced or disappeared. In showing the esophageal function, DDCR was
significantly superior to CDCR(χ²=4.50, Р
