肠重复畸形(intestinal duplication,ID)是一种少见的先天性肠道畸形,常发生于婴儿和儿童,可发生于从口腔至肛门的任何部位,小肠多见,尤以回肠和回盲部最常见[1]。由于发病位置不同,临床表现各异,可仅表现为呕吐和胀气,也可并发肠扭转和肠套叠[2]。因其临床和影像学表现缺乏特异性,术前确诊率较低。
核素显像诊断小肠重复畸形一例

摘要: 肠重复畸形是少见的先天性疾病,临床表现无特异性,术前诊断困难,以往辅助检查多采用消化道造影、超声、CT等。笔者通过一例99TcmO4-异位胃黏膜显像诊断小肠重复畸形的病例并文献复习,旨在强调核素显像具有简单易行、灵敏度高的优点,可供临床作为诊断肠重复畸形的选择,对小儿下消化道出血病因的寻查有重大意义。Abstract: Intestinal duplication is a rare congenital disease. Its clinical manifestations are nonspecific, and preoperative diagnosis is difficult. Gastrointestinal angiography, ultrasound, and CT are often used to detect this disease. A case of small intestinal duplication can be diagnosed through 99TcmO4− imaging. The advantages of this radionuclide imaging have been emphasized in literature. It can be used to diagnose intestinal duplication and help identify causes of lower gastrointestinal bleeding in children.
