【摘要】 目的探讨超声内镜(EUS)对鉴别十二指肠囊肿和脂肪瘤的诊断价值。方法回顾性分析我院2006年4月至2010年10月间经病理证实的20例十二指肠囊肿和14例脂肪瘤患者的内镜及EUS影像特征,记录病变的部位、大小、起源层次、表面形态、回声特征及治疗情况,比较两者影像特征。结果十二指肠囊肿和脂肪瘤的病变大小具有明显区别[(8.2±3.4)mm vs(12.6±5.0)mm,P<0.05),EUS下的回声也有统计学差异(囊肿呈无或极低回声vs脂肪瘤呈高回声,P<0.05),而病变发生部位、起源层次、病变表面形态上的差异无统计学意义(P>0.05)。结论 EUS对十二指肠囊肿和脂肪瘤具有重要的鉴别诊断价值,因而为制定安全和经济的治疗方案提供了重要指导。更多还原

【Abstract】 Objective To investigate the usefulness of endoscopic ultrasonography(EUS) in differentially diagnosing cysts and lipomas in the duodenal tract.Methods EUS images of pathologically confirmed,14 cases of cyst and 20 cases of lipoma were collected between April 2006 and October 2010.These lesions were compared in location,size,origin,margin and internal echo pattern.Results The cysts and lipomas were significantly different in size[(8.2±3.4)mm vs(12.6±5.0)mm,P<0.05].They were also different in the internal echo pattern(cysts echoless or low-level echo vs lipomas high-level echo(P<0.05).By contrast,there were no statistical differences(P>0.05) in the lesion location,origin and margin.Conclusion EUS is a valuable tool to differentiate cysts and lipomas in the duodenal tract,thus providing guidance for making safe and cost-effective treatment plans.更多还原
