目的 总结和分析胃肠道平滑肌肿瘤的诊治经验。方法 对２５ 例胃肠道平滑肌肿瘤的临床资料进行了回顾性分析，其中平滑肌瘤１３ 例，平滑肌肉瘤１２ 例。结果 １９ 例（７６％ ）胃肠道平滑肌肿瘤发生于胃和小肠；主要临床症状为消化道出血、贫血和腹痛；良、恶性肿瘤之间存在明显的临床差异；１６ 例（６４％ ）借助 Ｘ 线钡剂造影和内镜检查于术前确诊；全部病例均接受手术治疗，转移复发率１２％ 。结论 Ｘ 线钡剂造影和内镜检查是诊断胃肠道平滑肌肿瘤的有效方法；治疗以手术切除为主，肿瘤局部切除和相应脏器的部分切除术疗效肯定。
Objective To summarize and analyze the experience of diagnosis and treatment of gastrointestinal smooth muscle tumors. Methods The clinical data of 25 cases of gastrointestinal smooth muscle tumors were retrospectively analyzed, including 13 cases of leiomyomas and 12 cases of leiomyosarcoma. Results Twenty-nine (76%) gastrointestinal smooth muscle tumors occurred in the stomach and small intestine; the main clinical symptoms were gastrointestinal bleeding, anemia and abdominal pain; there were obvious clinical differences between benign and malignant tumors; 16 patients (64%) took advantage of X. Line thrombocytomas and endoscopy were confirmed before surgery; all cases were treated with surgery, and the metastatic recurrence rate was 12%. Conclusion X-ray barium angiography and endoscopy are effective methods for diagnosing gastrointestinal smooth muscle tumors. The main treatment is surgical resection. Local resection of the tumor and partial excision of the corresponding organs are effective.
