【摘要】 目的探讨MSCT对小儿消化道重复畸形的诊断价值。方法回顾性分析经手术及病理证实的30例消化道重复畸形患儿的临床及MSCT资料。结果 30例患儿中,囊肿型ATD 25例(83.3%),其中肠外型ATD 23例,肠内型ATD 2例;管状型ATD 5例(16.7%)。MSCT表现为单房囊肿型或管状型肿块,肿块内为液性密度,肿块壁与邻近主肠管壁厚相近或增厚;增强扫描示肿块壁均匀明显强化,肿块内无强化。手术及病理结果示,食道重复畸形4例,胃重复畸形1例,小肠重复畸形22例(十二指肠重复畸形1例、空肠重复畸形6例和回肠重复畸形15例),结肠重复畸形3例。结论小儿消化道重复畸形MSCT表现具有一定的特征性,临床表现多样,两者结合对术前诊断具有重要的意义。更多还原

【Abstract】 Objective To investigate the value of multislice spiral CT( MSCT) in the diagnosis of alimentary tract duplications( ATD) in children. Methods Clinical and MSCT data of 30 children with surgery and pathology confirmed ATD were retrospectively analyzed. Results Among the 30 children,cystic ATD was found in 25( 83. 3%),23 cases of parenteral ATD and 2 cases of intestinal ATD,and tubular ATD in 5( 16. 7%). MSCT showed unilocular cystic or tubular mass with fluid density and similar or increased thickness of mass wall and adjacent bowel wall. The enhanced scan showed uniform enhancement of mass wall without enhancement in mass. Surgical and pathological results showed esophageal duplication in 4 cases,stomach duplication in 1 intestinal duplication in 22( 1 case of duodenal duplication,6 cases of jejunal duplication and 15 cases of ileal duplication),and colonic duplication in 3. Conclusion ADT has specific MSCT findings and multiple clinical manifestations in children. The combination of them has decisive significance for preoperative diagnosis of ATD.更多还原
