摘　　要：目的　提高消化道平滑肌肿瘤的临床X线诊断水平。方法　回顾分析经手术和病理证实的 40例消化道平滑肌肿瘤的临床和X线检查资料。结果　食管 15例 ,其中平滑肌瘤 14例 ,平滑肌肉瘤 1例。主要X线表现 :管腔内充盈缺损、粘膜皱襞展平、管腔增宽、管旁肿块。胃肠 2 5例 ,平滑肌瘤 6例 ,平滑肌母细胞瘤 7例 ,平滑肌肉瘤 12例。X线表现取决于肿瘤的生长方式。可分为 :腔内型 ,腔外型 ,腔内外型及肌间型。前三者主要表现 :①腔内充盈缺损或软组织块影 ;②肿瘤中央龛影 ;③肿瘤坏死囊变 ;④胃肠本身及邻近器官受压移位 ;⑤偶见肿瘤钙化。肌间型病变较小 ,X线检查不易发现。结论　依照上述X线表现 ,术前可以作出正确诊断。Objective To improve the diagnostic quality of tumors composed of smooth muscles in alimentary tract.Methods The clinical and X-ray date of 40 cases of smooth musles tumors confirmed by surgery and pathological examination.Results Fifteen cases in the esophagus (including leiomyoma 14,leiomyosarcoma 1)showed the following X-ray appearence:filling defect,unfolding of mucous membrane,widening of the canal and pericanal mass 25 cases in the stomach and intestine(including leiomyoma 6,leiomyoplastoma 7,leiomyosarcoma 12)showed the following X-ray changes depending on the way of tumor,grows,cyst formation caused by tumor necrosis,compression of the stomach or intestine and adjacent organs,rarely seen calcification in tumor.The X-ray changes of small intermascular leiomyoma were short of specific X-ray signs.Conclusion X-ray exeamination is a reliable diagnostic method for smooth muscles tumors in alimentary tract.
