摘　　要：目的探讨儿童肠重复畸形的超声、CT、空气灌肠的影像学表现特征,提高术前诊断率。方法回顾性分析经手术病理证实的22例肠重复畸形患者的影像学资料。结果15例行超声检查,12例检出囊性灶,囊肿壁呈典型“双环征”及“Y征”;12例行CT增强检查,11例检出囊性灶,囊肿壁与肠壁强化方式相似;8例行CT平扫检查,仅3例检出囊性灶,且未显示特征性征象;3例继发肠套叠患者行空气灌肠,1例反复肠套叠未整复成功,2例整复成功后在回盲部仍见包块影。结论CT平扫检查对儿童肠重复畸形诊断价值较低,联合运用超声及CT增强检查可提高其术前诊断率。对于反复肠套叠及空气灌肠整复成功后回盲部仍见包块影者,需考虑肠重复畸形的可能。Objective To investigate the imaging features of ultrasound,CT and air enema in children with intestinal duplications,and to improve the preoperative diagnosis rate.Methods The imaging data of 22 cases with intestinal duplications confirmed by operation and pathology were analyzed retrospectively.Results Fifteen cases underwent ultrasound,in which 12 cases showed cystic lesions,and the cyst wall showed typical“double ring sign”and“Y sign”.12 cases underwent enhanced CT examination,in which 11 cases showed cystic lesions,and the enhancement pattern of the cyst wall was similar to that of intestinal wall.8 cases underwent CT plain scan examination,but only 3 cases showed cystic lesions and no characteristic signs were found.3 patients of secondary intussusceptions underwent air enema,in which 1 case of recurrent intussusceptions was unsuccessful,and 2 cases still showed masses in the ileocecal region after successful reduction.Conclusion CT plain scan has low diagnostic value for intestinal duplications in children,and the combination of ultrasound and CT enhanced examination can improve the preoperative diagnosis rate.For patients with recurrent intussusceptions and successful air enema reductions,if masses are still seen in the ileocecal region,the possibility of intestinal duplications should be considered.
