超声内镜与螺旋CT检查对胃淋巴瘤诊断价值的比较

摘要

目的 为胃淋巴瘤临床诊断方法提供内镜与影像学的选择依据,提高该病的临床诊断水平.方法 回顾分析22例原发性胃淋巴瘤患者超声内镜(EUS)与多层螺旋电子计算机断层扫描(MSCT)的检查结果,比较胃淋巴瘤患者在两种检查方法中的特征性表现,以评价两种方法对该病的诊断价值.结果 MSCT与EUS比较,两者对于胃淋巴瘤的多部位累及、累及范围、胃壁厚度、胃腔僵硬度、淋巴结累及、浆膜层累及和胃外其他器官的侵犯等比较差异均无统计学意义(P＞0.05),而对病灶处胃壁层次结构的辨认比较,EUS比MSCT优势明显,两者比较差异有统计学意义(P＜0.05).结论 EUS与MSCT检查对胃淋巴瘤均有相当的诊断价值,对于胃壁病灶层次结构的显示,EUS较MSCT有较明显的优势,两者结合能提高胃淋巴瘤的诊断率.%Objective To investigate the value of endoscopic ultrasonography(EUS) and multi-slice computed tomography( MSCT) in the diagnosis of gastric lymphoma. Methods 22 patients with surgically and pathologically proved gastric lymphoma were collected and retrospectively analyzed, MSCT scanning and EUS were performed in all 22 cases. Compared the two methods of the ability to find the characteristic performance of gastric lymphoma,and then evaluating the value of the two checks in diagnosis of this disease. Results Some important indicators were observed, such as muti-site involvement, range of the lesions,gastric wall thickening,stiffness of gastric cavity .intumescent lymphnodes,invasion of serosa and other organs, in these indicators there were no significant difference between the EUS and MSCT, but the ability of EUS in identifing the gastric wall structure in the lesion zone was better than MSCT( P < 0.05 ). Conclusion Both EUS and MSCT have considerable value in diagnosis of the gastric lymphoma. The EUS have more advantage in identifing the structure of the lesion in gastric wall. We can improve the accuracy in diagnosis of gastric lymphoma by combination.
