小肠原发性恶性肿瘤54例临床分析

（目的）总结小肠原发性恶性肿瘤的诊断及治疗。（方法）回顾分析54例经手术病理证实原发性小肠恶性肿瘤的临床资料。（结果）平均发病年龄41．3岁，30岁～60岁占70．4％。腺癌中位发病年龄49岁，十二指肠为其好发部位，占52．2％（12／23）。平滑肌肉瘤为51岁，空肠占54．5％（6／11）。淋巴肉瘤40岁，回肠占73．7％（14／19）。常见症状为腹痛51．9％（28／54）和腹块46．2％（25／54）。术前确诊率13．0％。术后5年生存率25．3％。（结论）小肠原发性恶性肿瘤以腹痛腹块为主要表现。全小肠X线钡餐检查、胃镜、ERCP等检查诊断意义较大。治疗以手术为首选。
