多层螺旋CT对十二指肠憩室的诊断价值

THE DIAGNOSTIC VALUE OF MULTISLICE SPIRAL CT IN THE DIAGNOSIS OF DUODENAL DIVERTICULUM

目的:分析十二指肠憩室的多层螺旋CT(MSCT)表现,探讨MSCT对该病的诊断价值。方法:分析21例共27个十二指憩室的MSCT表现,所有病例均经胃十二指肠造影、胃十二指肠内窥镜检查或ERCP检查证实。结果:发生于十二指肠降段内侧壁16个,水平段6个,胆总管开口附近5个。憩室表现为紧贴于十二指肠壁外的圆形或类圆形囊袋状影,16个囊内表现为气液平,3个仅为气体密度,8个囊内为混杂密度。结论:MSCT是发现十二指肠憩室的有用检查手段,可提供更多的诊断信息。

Objective： To analyze the features of duodenal diverticulum under muhislice spiral CT and to evaluate its value in the diagnosis of the diease. Methods： The features of total 27 duodenal diverticulums in 21 patients were analyzed retrospectively. All the cases were confirmed by esophago-gastro duodenoscopy or ERCP. Results： 16 lesions loeated at the medial wall of descent section of duodenum, 6 lesions located at the transversal section of duodenum and 5 lesions located near the opening of common bile duet. The diverticula were eiueular or semicircular in shape, containing air bubble, air-fluid level or mixed air, fluid and food debris.Conclusioa：Multisliee spiral CT is a useful technique to detect duodenum diverticulum and could provide more imformation for diagnosis.
