目的:探讨食管多原发癌的X线诊断价值。方法:7例食管多原发癌,全部采用低张气钡造影得以确诊,并由病理活检证实,最后与内镜检查对比研究。结果:7例食管多原发癌共发现14个病灶,每例均为2个,每个病灶均有进展期食管癌的一般X线特征。其中增生型5个,髓质型4个,浸润型3个,溃疡型2个。每例两处病灶间距均大于5cm,最长为12.5cm,平均7.4cm。增生型病变范围局限,平均长度2.6cm,髓质型病变范围较广,平均长度7.1cm。结论:食管多原发癌临床少见,易漏诊,X线低张气钡双重造影是诊查食管多原发癌的主要手段,病灶检出率较内镜更可靠。
Objective: To explore the value of X-ray diagnosis of multiple primary esophageal cancer. Methods: Seven cases of multiple primary esophageal cancer were confirmed by low-contrast barium angiography and confirmed by pathological biopsy. Finally, they were compared with endoscopy. Results: A total of 14 lesions were found in 7 cases of multiple primary esophageal cancer, with 2 cases in each case. Each lesion had the general X-ray features of advanced esophageal cancer. Among them, 5 were proliferative, 4 medullary, 3 infiltrative and 2 ulcer. Each case of two lesions were greater than 5cm spacing, the longest 12.5cm, an average of 7.4cm. Proliferative lesions limited range, the average length of 2.6cm, medullary lesions a wide range of average length of 7.1cm. Conclusions: Multiple esophageal primary cancers are rare and easily misdiagnosed. X-ray low contrast barium double contrast imaging is the main method to diagnose multiple primary esophageal cancer. The detection rate of lesions is more reliable than that of endoscopy.
