| 目的 探讨超声在诊断肠息肉引起的小儿继发性肠套叠中的价值,并总结其声像图的特点,为临床治疗方式的选择提供依据。 方法 本文回顾性分析我院2010年1月至2017年5月肠息肉致肠套叠患儿36例,均进行使用彩色多普勒超声低频和高频探头进行腹部扫查,分析其临床表现、超声图像、治疗及预后。结果 36例患儿年龄1月至11岁,临床症状主要包括阵发性哭吵、腹痛、血便及呕吐。36例患儿均具有肠套叠的典型超声声像图表现,即短轴呈“同心圆”征,长轴呈“假肾”征,超声诊断结果与临床诊断一致；其中10例(27.8％)超声诊断出息肉病变,声像图表现为在套头内或套头边缘发现实质性病变,为中等回声,CDFI可见丰富的放射状血流信号,明确诊断后,临床采用空气灌肠后行电子肠镜息肉切除术,顺利恢复出院；仍有26例患儿超声仅发现肠套叠征象,行空气灌肠后又复发肠套叠,23例(63.9％)患儿行剖腹探查及肠息肉切除术,3例(8.3％)患儿行剖腹探查及肠切除肠吻合术。结论 彩色多普勒超声检查诊断小儿肠套叠的敏感性和特异性极高,在对于肠息肉引起的小儿继发性肠套叠的诊断中,能发现息肉明确病因,指导治疗方式的选择。 |

| Abstract: |
| Objective To assess the ability of the color doppler ultrasound to detect intussusception owing to colonic polyp in children.Method Review of the records and imaging studies of 36 children with intussusception due to polyp diagnosed between 2010 to 2017.Results The intussusception were depicted on sonography in 36(100％)of 36 patients. 10 cases (27.8%) by ultrasound in the diagnosis of polypoid lesions, which showed that lesions are medium echo and with abundant radial blood flow signals. Intestinal polyps were not found in 26 cases.According the results,the appropriate surgical treatment is given to the patient.conclusion The sensitivity and specificity of color Doppler ultrasonography in diagnosis of intussusception in children are very high. The color Doppler ultrasound can find polyps ,which help find the cause of intussusception. |
