原发性小肠肿瘤发病隐袭,症状不著,早期诊断不易,常被误诊。许多患者常延至出现并发症才急诊手术。我们于1988年以来收治20例,均经手术和病理活检证实,特报告如下。1 临床资料1.1 一般资料:20例中男11例,女9例;年龄19～57岁,平均39.6岁。良性肿瘤平均年龄46岁;恶性36.7岁。患者自觉症状至出现并发症时间为68天～3.5年。13例在1年内,恶性10例,良性3例。肿瘤类别和发病部位见附表。 Involvement of primary small bowel tumors with insidious symptoms, early diagnosis is not easy, and often misdiagnosed.

The special report is as follows. 1 clinical data 1.1 General Information: 20 cases of 11 males and 9 females; aged 19 to 57 years, mean 39.6 years.
