摘　　要：目的探讨肠道超声诊断新生儿坏死性小肠结肠炎(NEC)后肠狭窄的价值。方法对50例新生儿行肠道超声检查,将其分为NEC后肠狭窄组(27例)和正常组(23例),记录两组肠管形态、血供,测量肠壁厚度及肠系膜上动脉(SMA)血流动力学参数,比较两组肠壁厚度及血流动力学参数差异。结果NEC后肠狭窄超声表现为狭窄段肠管形态僵硬,管腔细小,肠壁增厚,回声减低,血流丰富;狭窄近端肠管扩张,远端空虚。NEC后肠狭窄组SMA收缩期峰值流速与正常组差异无统计学意义(P>0.05);舒张末期流速、阻力指数差异有统计学意义(P<0.05)。结论超声可明确诊断NEC后肠狭窄,显示肠壁血供情况,为临床诊疗提供参考。Objective To evaluate the diagnostic value of bowel ultrasound for intestinal stricture post-necrotizing enterocolitis(NEC).Methods Fifty newborns were divided into group with intestinal stricture post-NEC(27 cases)and the control group(23 cases).Intestinal morphology,blood perfusion,intestinal wall thickness and hemodynamic parameters of superior mesenteric artery(SMA)were recorded.The intestinal wall thickness and hemodynamic parameters of SMA was compared.Results The main characteristics of intestinal stricture post-NEC were stiff shape,narrow lumen,thicken of bowel wall,hypoechoic and rich blood flow in bottleneck.The EDV-SMA was lower,the RI and intestinal wall thickness was higher in group with intestinal stricture post-NEC(P<0.05).Conclusions Bowel ultrasound could provide useful information for the diagnosis of intestinal stricture post-NEC.
