原发性胆囊癌超声诊断评价及漏误诊原因分析

目的：评价超声对原发性胆囊癌的诊断价值及漏误诊原因分析。方法选择胆囊占位病变98例，对其术前超声声像图表现进行分析，并与病理结果对照，重点分析超声诊断胆囊癌漏、误诊原因。结果经手术病理证实胆囊癌70例，超声诊断胆囊癌与病理结果对照符合率为75．7％（53/70）；漏诊15例，漏诊率为21．4％（15/70），其中结节型5例（33．3％），厚壁型9例（60．0％），混合型1例（6．7％）；误诊2例，误诊率为2．9％（2/70），皆为实块型。结论超声诊断胆囊癌有较高的准确率，超声诊断胆囊癌的主要易漏诊类型为结节型和厚壁型，易误诊类型为实块型。

Evaluation on ultrasonic diagnosis of the primary gallbladder carcinoma and analysis on the causes of missed diagnosis and misdiagnosis

Objective To evaluate the value of ultrasonic diagnosis of the primary gallbladder carcinoma and analyze the causes of missed diagnosis and misdiagnosis.Methods 98 cases with gallbladder occupying le-sions were collected to carry out a retrospective study and make a contrast of pathology results on the pre-operative sonogram and the causes of missed diagnosis and misdiagnosis were mainly analyzed.Results 70 cases of gallbladder carcinoma was confirmed by operation and pathology,accuracy：75.7%（53/70）;15 cases of missed diagnosis：21.4% （15/70）,and among them,5 cases of nodular type （33.3%）,9 cases of thick-wall type （60.0%）,1 cases of mixed type（6.7%）;2 cases of misdiagnosis：2.9%（2/70）,both solid biock.Conclusion The ultrasound diagnosis of gallbladder carcinoma had a higher accuracy.The main types of easily-missed diagnosis in ultrasound diagnosis gallbladder carcinoma were nodular type and thick-wall type,and the easily-misdiagnosed type is solid biock.
