7例原发十二指肠恶性肿瘤X线诊断

X-ray Diagnosis of Primary Malignant Tumor of Duodenum

目的探讨十二指肠原发恶性肿瘤的X线诊断价值,旨在提高对本病的早期诊断水平。方法本组7例均行上消化道X线造影检查(其中3例行低张造影),同时均行内窥镜检查,6例同时行CT检查。结果5例手术切除,2例内窥镜活检证实,将X线所见与病理结果对照,腺癌4例,平滑肌肉瘤2例,类癌1例。本组病例X线造影检查全部发现病变,其中5例定性诊断正确,正确率达77.8%。结论X线检查是发现和诊断十二指肠病变的首选方法,当X线征象不典型尤其是早期病变,应结合内窥镜进行组织学诊断,CT是两者的补充。

Objective To discuss the diagnostic value of X- ray for primary malignant tumor of duodenum to improve the diagnostic level in early stage. Methods 7 cases were detected with X- ray opacification of upper digestive tract meanwhile the endoscope was taken. There were 6 cases detected with CT scan. Results 5 cases had underwent operation and 2 cases had obtained diagnosis with biopsy of endoscope. There were 4 cases of adenocareinoma, 2 cases of leiomyoma and 1 case careinoid. The diagnostic rate was 77.8 % that obtained from X - ray detection. Conclusion Tne X- ray might be the first choice to diagnose the primary duodenum tumor. Tne combination with endoscope and CT detection might be taken to supplementary early diagnosis.
