目的探讨胃肠道间质瘤(GIST)的临床诊断方法。方法回顾性分析88例GIST患者的临床表现、影像学资料、胃肠镜、超声内镜(EUS)的结果,并进行分析、总结。结果 GIST缺乏特异性症状或体征;88例行腹部彩超发现16例病变,腹部彩超仅能发现腔外、转移病灶和少部分腔内病灶,价值不大;46例行腹部CT发现32例病变,腹部螺旋CT检查可发现较大病灶并且有助于判断胃肠间质瘤的危险性,对有无转移也有明确的诊断价值,但对于微小病灶的检出有一定困难;53例胃或结直肠病变的患者胃肠镜检查发现率为100%,但难以对病变进行定性;53例胃或结直肠病变的患者EUS误诊为其他疾病的有6例,对GIST的定性和定位有较好的辅助价值,但与病理结果之间仍有一定的出入。结论结合多种检查手段对明确GIST的诊断有重要价值,但确诊仍需病理检查。
Objective To investigate the clinical diagnosis of gastrointestinal stromal tumors (GIST). Methods A retrospective analysis of 88 cases of GIST patients with clinical manifestations, imaging data, gastrointestinal endoscopy, endoscopic ultrasonography (EUS) results, and analyzed and summarized. Results There were no specific symptoms or signs of GIST. Eighty-six cases were diagnosed by abdominal color Doppler imaging. Abdominal ultrasonography showed only extraluminal and metastatic lesions and a few intracavitary lesions, which were of little value. Forty-six cases were examined by abdominal CT, Abdominal helical CT can detect larger lesions and help determine the risk of gastrointestinal stromal tumors, with or without metastasis also has a clear diagnostic value, but for the detection of minimal lesions have some difficulties; 53 cases of stomach or colorectal Lesions were found in patients with gastrointestinal endoscopy was 100%, but difficult to characterize the disease; 53 cases of gastric or colorectal lesions misdiagnosed as other diseases EUS in 6 cases, the qualitative and localization of GIST has a good auxiliary Value, but still some discrepancies with the pathological results. Conclusion Combined with a variety of inspection methods for the diagnosis of clear GIST has important value, but the diagnosis still need pathological examination.
