摘要
目的探讨小儿肠套叠超声声像图特征及其临床意义。方法回顾性分析了75例小儿肠套叠的二维及彩色多普勒（CDFI）超声声像图特征，并与空气灌肠复位及手术治疗结局相对比。结果（1）75例小儿肠套叠超声分型：回结型58例（58／75，77．3％），小肠型8例（8／75，10.7％），结肠型9例（9/75，12．0％）。回结型、结肠型患儿的脂肪内核厚度与鞘壁厚度比值〉1，小肠型脂肪内核厚度与鞘壁厚度的比值〈1。（2）透视下空气灌肠复位73例（73／75，97.3％），直接手术治疗2例（2／75，2．7％），73例空气灌肠复位成功63例，复位成功率86．3％，复位失败后手术治疗10例（10／73，13．7％）。套叠部长度〉50mm、套叠部伴有肠管积液及CDFI血流未探及的患儿，与套叠部长度〈50mm、套叠部不伴有伴有肠管积液及探及CDFI斑流患儿比较，空气灌肠复位成功率低，且差异均有统计学意义（P〈0．01）。套叠部有淋巴结与无淋巴结比较，空气灌肠复位成功率有差异，但差异无统计学意义（P〉0．05）。结论超声不仅能对肠套叠作出早期诊断，还能通过了解分型、套入部长度、肠管积液及血运状况等超声特征，对空气灌肠复位的风险做出评估，为临床选择合适的复位方式及评估预后提供重要信息。
Objective To explore the ultrasonic features of intussusception and their clinical significance. Methods A retrospective analysis of ultrasonic features was conducted on 75 cases of intussusception by B-fl0w and color Doppler flowing imaging（CDFI） ,comparing with the results of air enema and surgical operation. Results （1）The type of ultrasonography for intussuseeption：type ileo-colonic in 58（58/75,77. 3%）, type amall bowel in 8（8/75, 10. 7. %） ,type colonic in 9（9/75,12. 0%）. The ratio of fat kernel thickness to sheath cuticle thickness was less than 1 in the type of small bowel, but greater than 1 in the type of ileo-colonic and colonic. （2）Except for 2 cases with surgical operation,other 73 cases was treated by air enema reduction, There were 63（ 63/72,86, 3 %） eases treated by air enema reduction successfully and 10 cases with surgery after the failure of air enema reuction. Compared with the lead point＇s depth leas than 50mm or more than 50mm,with or without intestinal fluid and the blood flow signal detected or not, both results showed statistically difference（P〈0.01）. And there were no significance between the lead point＇s with lymph node and the lead point＇s without lymph node（P〉0.05）. Conclusion Ultrasound could diagnosed intussusception early and provided information of the type,intestinal fluid and circulation. Furthermore,by measuring lead point＇s depth of intussusception the Ask of air enema could be evaluated. Ultrasonographie characteristics of intussusception play an important role in treatment and prognosis assessment.
