小肠平滑肌肉瘤临床较少见,由于症状和体征不典型,故早期不易被诊断。自1985年以来我们共收治6例,均经手术和病理证实,现结合文献学习和病例分析,将其临床特点和手术诊治体会进行报告。 Intestinal leiomyosarcoma is rare in clinical practice. Because symptoms and signs are not typical, it is not easy to be diagnosed early. Since 1985, we have treated a total of 6 cases. All of them have been confirmed by surgery and pathology. Now we combine the literature learning and case analysis, and report on their clinical features and experience in surgical diagnosis and treatment.
