目的评价原发性胃肠间质瘤(GIST)各种常见诊断方法的优缺点。方法回顾性分析2004-12-01-2009-05-30复旦大学附属中山医院收治的70例GIST病人CT、内镜、超声内镜及超声检查资料。结果CT:腔外生长44例,腔内24例,跨壁2例;哑铃形或圆形44例,不规则26例;边界清43例,不清27例;动脉期连续性增强,静脉期不均匀增强26例,均匀44例。CT征象与恶性分级相关。GIST在内镜表现为光滑的黏膜隆起,在超声表现为低回声实性肿块。结论CT应首选用于GIST诊断、分级和制定治疗方案;内镜和超声内镜有助于诊断黏膜下肿瘤;其他方法可用于特定情况。
Objective To evaluate the advantages and disadvantages of various common diagnostic methods for primary gastrointestinal stromal tumors (GIST). Methods Retrospective analysis of CT, endoscopy, endoscopic ultrasonography and ultrasonography in 70 GIST patients admitted to Zhongshan Hospital of Fudan University from December 2004 to December 29, 2004. Results CT: There were 44 cases of extracavitary growth, 24 cases of intracavitary and 2 cases of transmural; 44 cases of dumbbell-shaped or round, irregular 26 cases; 43 cases of clear clearance, 27 cases of unclear; continuity of arterial phase, venous phase Unevenly enhanced in 26 cases, uniform 44 cases. CT signs and malignant grade related. GIST appears as a smooth mucosal bulge on the endoscope, presenting as a hypoechoic lump in ultrasound. Conclusion CT should be the first choice for the diagnosis, classification and treatment of GIST. Endoscopy and endoscopic ultrasonography are helpful to diagnose submucosal tumors. Other methods can be used in specific cases.
