辅助检查在小肠平滑肌肉瘤诊断中的应用

Application of adjunct examination in the diagnosis of small intestine leiomyosarcoma

小肠平滑肌肉瘤临床相当少见，因发病率低，临床表现又缺乏特异性，故诊断较困难。作者分析和讨论辅助检查对小肠平滑肌肉瘤的诊断意义，回顾了本院１９８４～１９９６年收治的２１例小肠平滑肌肉瘤临床病例，分析了辅助检查在本病诊断中的作用。结果是２１例小肠平滑肌肉瘤查Ｂ超检查１２例，阳性１１例。ＣＴ查７例，阳性７例。钡餐查１４例，阳性１０例。ＤＳＡ查６例，阳性６例。放射性核素显像３例，阳性３例。所以Ｂ超或ＣＴ检查能确定有无占位性病变。Ｘ线钡餐造影明确病变部位及病变与肠管关系。经上述检查仍无阳性发现者，而又高度怀疑本病，可行ＤＳＡ或核素检查。认为每种检查有其不同检查意义，应选择应用有助诊断。

Small intestine leiomyosarcoma is a rare disease and difficult to diagnose because of itsrare incidence and non-specific clinical feature. We reviewed 21 cases which were treated in our hospitalfrom 1984 to 1996. B-mode ultrasonography was performed on 12 out of 21 cases with positive result in11,CT made on 7 was all positive. Barium series on 14 found 10 with positive lesion. DSA performed on6 cases was all positive and all 3 cases undergoing nuclear imaging were found positive. The importanceof adjunct examination in the diagnosis of this disease was discussed.
