目的：探讨十二指肠恶性肿瘤的临床特点及 Ｘ 线征象与诊断在外科手术中的价值。方法： 采用胃肠气、钡双重造影和低张双重造影方法，分析了１ ２ 例经病理证实的十二指肠恶性肿瘤的临床及 Ｘ 线资料。结果：１２ 例中， 腺癌９ 例、恶性淋巴瘤２ 例及平滑肌肉瘤１ 例；病变位于十二指肠球部１ 例、乳头部５ 例、乳头上区４ 例、乳头下区２ 例； Ｘ 线表现为不规则狭窄及充盈缺损，亦见不规则腔内钡斑。结论：十二指肠恶性肿瘤 Ｘ 线表现有一定的特点，若能结合临床并仔细观察 Ｘ 线征象， 可减少误、漏诊。某些 Ｘ线征象对于决定能否外科手术切除具有重要临床价值。
Objective: To investigate the clinical features and the value of X-ray signs and diagnosis of duodenal malignancy in surgery. Methods: The clinical and X-ray data of 12 patients with pathologically confirmed duodenal malignancies were analyzed by gastroenterography and phlegm double contrast and low-intensity double contrast imaging. Results: In 12 cases, there were 9 cases of adenocarcinoma, 2 cases of malignant lymphoma, and 1 case of leiomyosarcoma. The lesions were located in 1 case of duodenal bulb, 5 cases of papillary head, 4 cases of supraspinal area, and 2 cases of submandibular area. X-ray showed irregular narrow and filling defects, also see irregular cavity freckle. Conclusion: The X-ray findings of duodenal malignant tumors have certain characteristics. If we can combine clinical and carefully observe the X-ray signs, we can reduce errors and missed diagnosis. Some X-ray signs have important clinical value in deciding whether surgical resection can be performed.
