胃平滑肌肿瘤（附21例报告）

本文对２１例经手术及病理证实的胃平滑肌肿瘤患者进行分析，其中良性肿瘤８例，恶性肉瘤１３例。临床观察表明：胃平滑肌肿瘤的症状及体征均无特异性，术前确诊较困难，ＣＴ、Ｂ超检查可有阳性发现，但不能作出病原学诊断。而Ｘ线造影及胃镜检查可以为诊断提供重要线索，但无助于良恶性肿瘤的鉴别。然而，有转移，体积偏大，多发于胃近端，体重下降明显及合并急性上消化道大出血等特点有利于肉瘤诊断，意外发现者多支持良性病变。手术切除是胃平滑肌肿瘤的主要治疗手段，凡良性肿瘤及病理提示低度恶性的肉瘤，根治术后随诊，其预后均较乐观。

Leiomyoma of stomach:report 21 cases

patients with gastric leiomyoma diagnosed by pathology and operation were reported.8 of 21 patients were benign leiomyoma and other 13 patients were malignant leiomysarcoma.The clinical observation showed that there are no specificity in the symptoms and physical examinations of the patients.CT and ultrasonography have some positive findings,but don't have any etiological meanings.Examination of x-ray and endoscopy may proved some important clues for diagnosis,but not for differential diagnosis between the benign tumor and the malignant one.However,the patient having serious weight loss,metastasis,and tumor large in size and location in the upper part of stomach suggest malignancy.Surgical treatment was primary choice.In the case of benign leiomyoma and leiomyosarcoma with high differentiation,prognosis was better.
