摘　　要：目的：探讨多层螺旋CT（MSCT）对十二指肠乳头旁憩室的诊断价值。方法：对经MSCT和上消化道钡餐（GI）检查确诊的60例十二指肠憩室患者的临床和影像资料进行回顾性分析。结果：60例患者共发现十二指肠憩室73个,其中乳头旁憩室58个。73个憩室中,直径小于10 mm者11个,10-20 mm者38个,大于20 mm者24个。十二指肠乳头旁憩室表现为十二指肠腔外的囊状突出,可呈液性囊状影、液-气囊状影及气囊状影等,大部分位于十二指肠与胰头之间。MSCT能发现小于10 mm的憩室。结论：MSCT能同时发现十二指肠乳头旁憩室及其伴发的胆胰疾病,对判断两者的关系具有较重要的临床价值。影像科医师应重视对十二指肠乳头旁憩室的诊断。Objective. To evaluate the findings and the diagnostic value of multi-slice helical CT（MSCT） scanning in juxta-papillary duodenal diverticula （JPD）. Methods： Clinical materials and imaging findings of 60 patients with duodenal diverticulum provided by MSCT and GI were retrospectively analysed. Results： In 60 patients, 73 duodenal diverticula were detected, 58 of whom were JPD. Of 73 diverticula, 11 cases were less than 10mm in diameter,38 cases were 10-20mm in diameter and 24 cases were larger than 20mm in diameter. JPD were extraluminal cystic outpouching of duodenum, and it might manifest as fluid, fluid-air and air density,most of them were located between duodenum and pancreatic head. MSCT could detect duodenal diverticula which sizes were less than 10mm in diameter. Conclusion. MSCT can simultaneously detect duodenal diverticula and biliary-pancreatic diseases. It is of value in evaluating the relationship between duodenal diverticula and biliary-pancreatic diseases. The diagnosis of duodenal diverticulum should be considered.
