彩色多普勒超声对小儿肠套叠的诊断价值(附76例报告)

The Diagnostic Value of Ultrasound in Pediatric Intussusception

目的探讨彩色多普勒超声在小儿肠套叠诊断中的应用价值。方法 76例肠套叠患儿经彩色多普勒超声检查,探讨其超声影像学特征。结果 76例患儿均查见边缘清晰、界限清楚、回声不均的腹部包块,横切面呈"同心圆征"或"靶环征",纵切面呈"套管征"或"假肾征";同时8例包块上方见肠管扩张,且肠蠕动减弱或亢进,合并肠壁水肿;68例患儿测得肠壁血流信号,空气灌肠复位成功,8例未测得血流信号,空气灌肠复位成功4例,另4例转手术治疗;16例肠系膜淋巴结肿大,淋巴结边缘清晰、分界清楚、形态规则、皮髓质清晰。结论彩色多普勒超声在小儿肠套叠诊断中,准确率高,可重复性好,同时为非侵入性检查,对患儿无创伤,无辐射,操作简便,值得推广应用。

Objective To discuss the diagnositic value of ultrasound in pediatric intussusception.Methods 76 children with intussusception were detecited with color doppler ultrasound,and the ultrasound imaging features were discussed.Results All the children with intussusception were found with clear edge,clear boundaries,uneven echo abdominal mass,with cross section ＂concentric circle sign＂ or ＂target sign＂,longitudinal section ＂casing syndrome＂ or ＂false renal syndrome＂;there were dilatation of intestine with bowel wall edema above the mass in 8 cases,and intestinal peristalsis weaken or hyperthyroidism;bowel wall flow signal were measured in 68 cases,then treated successfully with air enema reduction,blood flow signal were not measured in 8 cases,treated successfully with air enema reduction in 4 cases,the other 4 cases transitted surgical treatment;16 cases with mesenteric lymph nodes,lymph node with clear edge,clear boundary,regular shape,skin marrow clear.Conclusion Color Doppler ultrasound has high accuracy,good repeatability,and is non-invasive,no trauma,without radiation in diagnosis of pediatric intussusception,it＇s easy operation,worthy of promotion.
