【摘要】 目的：探讨诊断原发性十二指肠恶性肿瘤的方法。方法：回顾分析１９９５～２０００年２８例十二指肠恶性肿瘤患者的临床资料，分析辅助检查对十二指肠恶性肿瘤的诊断价值。结果：胃十二指肠镜检查１６例，阳性率９３．７５％（１５／１６），均为十二指肠上部和乳头周围部肿瘤。十二指肠低张造影 １３例，阳性率 ７６．９２％（１０／１３），包括十二指肠上部、乳头周围部和乳头下部肿瘤。腹部Ｂ超检查２８例，阳性率５３．５７％（１５／２８），均表现为胆管扩张。结论：胃十二指肠乳头下部肿瘤依赖于十二指肠低张造影。更多还原

【Abstract】 Objective: To evaluate the diagnostic methods of primary malignant tumors of duodenum. Methods: A retrospective analysis was conducted based on the clinical data of 28 patients with primary malignant tumors of duodenum. Results: Sixteen patients underwent endoscopic examination, 15 of them were positive (93.75%) with the tumors located at upper duodenum and around the papillae. Thirteen patients underwent hypotonic duodenogram and 10 of them were positive (76.92% ), with the tumors located both at upper and lower duodenum. 28 patients underwent ultrasonography, with the positive rate of 53.57% (15/28),all of them being cholangiectasis. Conclusions: Endoscopy was the main method for the diagnosis of tumors located at upper part and around the papillae of the duodenum,and hypotonic duodenogram was effective in the diagnosis of tumors located at lower duodenum.更多还原
