婴幼儿急性肠套叠的临床与影像学分析(附58例报告)

目的　探讨婴幼儿急性肠套叠的影像学表现及临床意义。方法　总结经手术证实的 58例婴幼儿急性肠套叠,分析腹部立位片和空气灌肠的X线改变及CT、超声的影像学表现。结果　(1)手术 58例肠套叠中回结型,回盲型 33例,回回结型,回盲结型,回结结型 25例。病理及手术证实肠套叠合并肠坏死 23例。(2)主要影像学表现:小肠结肠气体减少 12例,肠胀气和不全性肠梗阻 18例,小肠梗阻 17例,腹部立位无明显异常 8例。空气灌肠显示套头呈杯口状,分叶状包块影 28例。超声显示靶环征 3例,CT显示分层状同心圆形肿块 1例。结论　婴幼儿急性肠套叠影像学表现典型,对于诊断十分重要。

Clinical and Imaging Analysis of Acute Intussusception in Infant

Objective To discuss the imaging representations and its clinical significance of acute indigitation in infants.Methods The imaging representations including CT,ultrasonography stand abdominal plain film and gas clysters of indigitation comfirmed by operation in 58 infants were analysed.Results (1)Of 58 cases,33 were ileum-colon and ileum-caecal type,25 were ileum-ileum-colon,ilem-cecal-colon and ileum-colon-colon type;(2)The main imaging representations were as following:gas decreased in colon of small intestine (12 cases),inflation in intestine and incomplete ileus (18 cases),ileus of small intestine(17 cases),no abnormity on stand abdominal plain film (8 cases).Gas clyster showed the "goblet sign" and masses (28 cases).The sign of targed rings was seen on ultrasonography(3 cases).The layered homocentric round tumors showed by CT (1 case).Conclusion The imaging representations of acute indigitation in infants are typical,which are significant for the diagnosis.
