原发性小肠肿瘤45例临床诊断分析

原发性小肠肿瘤少见,约占消化道肿瘤的1.5％～2％。术前明确诊断困难。本文对我科1960年1月～1984月12月收治的45例的临床诊断进行了分析。文献报道误诊率为30.8～88％,本组为68.8％。误诊原因:(1)小肠肿瘤缺乏特征性的临床表现;(2)缺乏特有的诊断方法;(3)缺乏对小肠肿瘤的警惕性。本文强调了重视临床表现及提高对小肠肿瘤警惕的重要性。

A Clinical Analysis of 45 Cases of primary Small Bowel Tumors

Primary tumors of small intestine are rarely eucountered clinically and account about for 1.5-2% of all the gastrointestinal tumors. It is quite difficult to establish the diagnosis preoperatively. In a 25-year-period from January I960 to December 1984, 45 patients with primary small bowel tumors were admitted to this institute, and their clinical data were analyzed. The rate of wrong diagnosis was 68.8% in this series as compared with 65% to 100% reported in the literature. The causes of misdiagnosis were as follows:1. There is usually no characteristic clinical sign.2. No specific diagnostic procedures are available.3. The clinicians do not have enough vigilance with this disease because of their rarity.It is emphasized that clinicians should be familar with the clinical signs and alert on the possibility of the disease.
