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 investigate the ultrasonographic features of liver metastasis of gastrointestinal stromal tumors (GIST) and the significance of postoperative ultrasound review. Methods 49 cases of GIST confirmed by ultrasonography and pathology were collected, of which 6 cases had simultaneous or heterotopic liver metastasis. The ultrasound features of these 6 cases were analyzed. Results Among the 6 patients with liver metastasis, ultrasonography showed that the primary tumor was a huge mixed echo mass with irregular shape and lobulation. The mucosal surface of the tumor surface was disrupted or ulcerated, and the adjacent gastric and intestinal wall thickening ; Simultaneous liver metastases were single or multiple, cystic solid echo more common, morphology, internal echo and primary tumor basically the same; heterotransplated liver metastases mostly solid inhomogeneous - hypoechoic, showing peritoneal and (Or) trunk muscle metastasis, no lymph node metastasis; imatinib mesylate treatment after ultrasound review, some metastases shrink, echo reduction. Conclusion Ultrasonography has important clinical diagnostic value for advanced GIST and its simultaneous or heterochromic liver metastases.
