超声内镜医师诊断胰腺囊性病变的一致性分析

Interobserver agreement of endoscopic ultrasonography for pancreatic cystic lesions

目的探讨胰腺囊性病变超声内镜(EUS)形态学特点在不同EUS医师之间的一致性。方法回顾性分析安徽医科大学第一附属医院2011年11月至2014年12月诊治的24例胰腺囊性病变患者EUS图像,2位EUS医师分析图像中是否存在间隔、固体成分和淋巴结肿大等特点。结果 2位EUS医师分析是否有固体成分的一致性较好(Kappa=0.647)。分析间隔、壁结节、边缘钙化、主胰管扩张、淋巴结肿大以及囊性病变数量方面一致性中等。结论不同EUS医师分析胰腺囊性病变EUS图像,存在主观差异。

Objective To evaluate the degree of inter-observer agreement between endosonographers for distinguishing EUS morphologic features of pancreatic cystic lesions.Methods From Nov 2011to Dec 2014, 24 cases of pancreatic cystic lesions were evaluated by EUS.The original endosonographic images were reviewed by two endosonographers.The EUS images were assessed for the presence or absence of the following morphologic characteristics： septae, solid component, lymphadenopathy, etc.Results There was substantial agreement between the two reviewers in interpreting the presence or absence of solid component （Kappa=0.647）.The presence or absence of a septae, mural nodule, peripheral calcification, main pancreatic duct dilation, lymphadenopathy and number of cysts showed moderate reliability between the two readers.Conclusion A great deal of subjectivity is foundin describing EUS features .
