128层螺旋CT对十二指肠乳头旁憩室诊断价值研究

Clinical Application of Periampullary Diverticula in 128-slice spiral CT

目的探讨MSCT后重组技术对十二指肠乳头旁憩室(PAD)的诊断价值和临床意义。资料与方法 60例经MSCT检查确诊的十二指肠乳头旁憩室的MSCT表现和临床资料进行回顾性分析。结果 60例患者共发现十二指肠乳头旁憩室64个,表现为十二指肠腔外的囊状突出,可呈液性囊状影、液-气囊状影及气体囊状影等,位于十二指肠降段与胰头之间。MPR重组技术从不同方位显示十二指肠乳头旁憩室形态、位置及与胆总管、胰腺之间的关系。结论 MSCT及其后重组技术有助于PAD的诊断,明确PAD与周围组织的关系,在PAD的诊断中具有较好的临床应用价值。

Objective To study the value and the clinical signification of MSCT in the diagnosis of Periampullary diverticula（PAD）, Materials and Methods Clinical materials and imaging findings of 60 patients with Periampullary diverticula provided by MSCT were retrospectively analysed. Results In 60 patients, 64 periampullary diverticula were detected.PAD were extraluminal cystic outpouching of duodenum,and it might manifest as the cystic shadow of liquid, liquid -air and air density,and were located between the drop segment of duodenum and pancreatic head. MSCT with reconstruction techniques could display the shape and location of periampullary diverticula and the relationship of com- mon bile duct and pancreas. Conclusion MSCT and the reconstruction technique was valueable in the evaluation of periampullary diverticula and its complication, and should be widely applied in the evaluation of periampullary diverticula.
