目的探讨腹部X线平片对婴儿肠套叠的临床诊断价值。方法回顾分析210例患者的临床资料。结果腹部平片表现如下:腹部肠腔气影明显减少,出现大片状无肠气区域,出现率为168/210,未见肠腔扩张积液等肠梗阻征象。表现为腹部致密呈极少气状态或腹部大部分区域较致密,而网格状的肠腔气影范围缩小,局限于腹部某一区域,上述征象立卧位腹部平片显示无明显差别,出现率为131/210;也可表现为腹部密实呈少气状态,出现连续性充气的肠管,出现率为32/210;肠腔出现明显扩张及积液,扩张肠腔呈“同心圆”状或“香蕉”状,卧位腹部平片显示较佳,为41/210;肠腔内软组织肿块。在肠腔气影的衬托下显示肠腔内软组织肿块,为51/210。此征可以在腹部密实呈少气状态出现,也可以在出现肠梗阻病例见到。结论婴儿肠套叠发生后较早的X线征象是腹部肠腔气影明显减少,出现大片状无肠气区域。 Objective To investigate the clinical value of abdominal plain radiography in the diagnosis of intussusception in infants. Methods The clinical data of 210 patients were retrospectively analyzed. Results The results of abdominal plain film were as follows: Gastrointestinal abdomen significantly reduced gas shadow, there is no large area of ​​intestinal gas region, the incidence was 168/210, no intestinal fluid such as intestinal obstruction signs. Manifested as dense abdominal gas was very little state or most of the abdomen more dense, and the narrow glenoid gut lumen limits confined to a certain region of the abdomen, the signs of lying supine abdominal plain film showed no significant difference occurred The rate was 131/210; also showed the abdomen was dense state was less gas, continuous inflatable intestinal appeared, the incidence was 32/210; significant expansion of the intestine and effusion, dilatation of the intestine was “concentric ” Shape or “Banana ” shape, abdominal plain radiographs showed better, as 41/210; soft tissue mass in the intestine. Show in the gut of the gut lumen soft tissue mass, 51/210. This sign can be dense in the abdomen showed a state of gas can also be seen in cases of intestinal obstruction. Conclusions The early X-ray signs of infantile intussusception were significantly reduced in the gastrogram of the abdominal intestine and the appearance of large, flat, non-intestinal gas region.
