摘　　要：目的探讨胃肠道间质瘤(GIST)肝转移的超声特点及术后超声复查的意义。方法收集经超声检查及病理证实的GIST患者49例,其中6例发生同时性或异时性肝转移,分析该6例患者的超声特点。结果 6例伴肝转移GIST患者中,超声示原发瘤为巨大混合性回声团块,形态不规则、有分叶,瘤体表面黏膜面中断或见溃疡,毗邻区胃(肠)壁增厚;同时性肝转移瘤呈单个或多个,囊实性回声多见,形态、内部回声与原发瘤基本一致;异时性肝转移瘤多为实性不均匀中-低回声,可见腹膜和(或)躯干肌肉转移,未见淋巴结转移;甲磺酸伊马替尼治疗后进行超声复查,部分转移瘤缩小,回声减低。结论超声检查对晚期GIST及其同时性或异时性肝转移瘤具有重要临床诊断价值。Objective To analyze the ultrasonic manifestations of gastrointestinal stromal tumors（GIST） with liver metastases,and to explore the value of ultrasonography reexamination in postoperative follow-up.Methods Among 49 cases of GIST confirmed with ultrasonography and pathology,homochronic or heterochronic liver metastases were found in 6 cases,and ultrasonic features of which were observed and analyzed.Results The primary tumuors were huge,and the shapes were irregular and lobulated with mixed echoes in patients with heterchronic liver metastases.The mucosa on the tumor surface was interrupted sometimes with ulcers,and the neighbouring muruls were thickened.Homochronic metastases were solitary or multiple with cystic echoes,the shapes and internal echoes of which were almost the same as primary tumors.Heterchronic liver metastases mostly showed uneven medium-low echoes,complicated with abnominal and/or body muscle metastases,but without lumphaogenous metastases.It was found that some mestastic tumors lessened and the echoes reduced after treatment with imatinib mesylate capsules.Conclusion Ultrasound has important value on terminal GIST and GIST with homochronic or heterochronic liver metastases.
