贲门癌的X线表现

X-Ray Manifestation of Cardia Cancer

目的：总结胃底贲门癌的x线特征性表现。材料与方法：20例由手术病理证实的胃底贲门癌患者（男性12例，女性8例，年龄45～72岁）均经x线钡餐造影检查，包括气钡双重造影和气腹胃壁造影，回顾性分析了所有患者的影像表现。结果：病变部位黏膜增粗、紊乱、中断消失占100％，胃泡内软组织肿块占60％，胃底僵硬变形占80％，恶性龛影占70％，食管下端变窄及钡流喷射现象占60％。结论：胃底贲门癌患者采用X线上消化道钡餐造影检查安全可靠，准确率高，同时可以弥补胃镜对容易遗漏的死角及功能性变化观察的不足。

Purpose： To summarize the radiographic features of gastric fundus and cardia cancers. Materials and Methods： Twenty patients （12men, 8 women, aged 45-72 years） with surgically and pathologically proved gastric fundus and cardia cancers underwent upper gastrointestinal barium meal tests which comprised double air-barium contrast GI study and air- abdomen gastric parietography. Imaging findings of all patients were analyzed retrospectively. Results ： The thickening, disor- der, interruption and disappearance of mucous membrane in the involved locations were found in all patients （100%） , the soft tissue masses in gastric bubbles were found in 12 cases （60%） , the rigidity and deformation of gastric fundi were found in 16 cases （ 80% ） , malignant niche shadows were found in 14 cases （ 70% ）, and lower segment narrowing of esophagus and ejec- tire phenomena of barium flow were found in 12 cases （60%）. Conclusion： Upper gastrointestinal barium meal examination for diagnosing gastric fundus and cardia cancers is a safe, reliable and high-accurate modality which may well compensate the defect of gastroscope for observing easily missing dead angles and functional changes.
