摘　　要：目的探讨胃肠道间质瘤(gastrointestinal stromal tumors,GIST)的临床特点及手术方法,提高诊治水平。方法回顾性分析55例胃肠道间质瘤患者的临床资料,对其临床特点、病理及免疫组织化学检测及手术方法进行总结。结果胃肠道间质瘤可发生于消化道的任何部位,以胃多见(56.3%),其次为小肠(38.2%)、结肠和直肠(3.6%)。免疫组织化学检测:CD117阳性53例,占96.4%;CD34阳性41例,占74.5%。手术方法为行胃大部切除27例(49.1%),小肠部分切除21例(38.2%),胃部分切除4例(7.3%)。结论胃肠道间质瘤治疗以手术为主,术中应根据肿瘤大小、部位、有无外侵及淋巴结转移确定手术范围,切除在于完全而不在于大范围清扫。Objective Summarize the clinical characteristics and surgical methods of gastrointestinal stroreal tumor to improve the diagnosis and treatment.
