原发性小肠肿瘤101例临床分析

本文对病理证实的１０１例原发性小肠肿瘤进行回顾性分析，结合文献对原发性小肠肿瘤的性质、临床表现、诊断方法进行讨论。本病好发于十二指肠（５２／１０１）、空肠（３０／１０１），回肠仅占１８．８１％（１９／１０１），由于缺乏特异性的临床表现，术前诊断率仅３５．６％，因此强调综合分析各种检查结果以提高术前诊断率。

Clinical analysis of 101 cases of primary small intestinal tumor

During theperiod 1980 1992, 101 cases of primary small intestinal tumor were treated surgicaly and proven phathologicaly. Among them, 74 cases were malignant (adenocarcinoma 51, lymphosarcoma 6, leiomysarcoma 6 and others 11) and 27 benign (leiomyoma 18. lipoma 4 and others 5). The tumors were located in ileum in 19, jejunum in 30,duodenum in 52. Because of their rarity and lack of characteritic feature, the preoperative diagnostic accuracy was only 35. 6% in this series.It is mandatory to perform hypotonic double contrast and endoscopy on individuals of suspicion as early as possible, but should be combined with other methods in order to improve diagnostic aceuracy.
