| 目的 探讨多向剪草机式超声扫描在小儿急诊肠套叠诊断中的临床价值。方法 临床疑为急性肠套叠的小儿患者1000人随机分为两组，常规组500人采用常规扫查方法扫查，即沿肠管走行和分布从右上腹连续扫查至左右下腹及盆腔，改良组500人采用多向剪草机式超声扫查方式扫描，即从四个不同方向别作一次类似剪草机工作路径的连续扫查，分别记录两组病例超声检查结果，并跟踪随访所有病例空气灌肠、手术或超声随访结果。比较两种超声扫查方式诊断小儿急性肠套叠的灵敏性、特异性和准确性。结果 两组比较特异性无明显统计学差异（P>0.05），但灵敏性和准确性改良组高于常规组，差异有统计学意义（P<0.05）。结论 多向剪草机式超声扫查比常规扫查方式更易于检出肠套叠，可减少漏诊，提高灵敏性，具有重要临床意义,建议在小儿急性肠套叠的临床诊断中推广应用。 |

| Abstract: |
| Objective To discuss the clinical value of the multi-directional lawn mower scanning(MDLMS) method with ultrasound on the diagnosis of pediatric acute intussusceptions. Method Cases of 1000 clinically suspected of intussusceptions were randomly divided into two groups: the routine group consisting of 500 cases examined by the routine scanning method, which is to scan continuously along the intestinal canal anatomical regions from right upper quadrant of abdomen to lower abdomen and pelvic cavity. and the improved group of 500 cases examined by the multi-directional lawn mower ultrasonic scanning method, which is to scan the abdomen continuously as the lawnmower work path each time respectively from four different directions. The ultrasonic examination results of the two groups were recorded respectively, and the air enema,surgery or ultrasonic follow-up results of all the cases were followed up, so as to compare the diagnostic sensitivity，specificity and accuracy of these two ultrasound scanning methods. Result These two groups showed no significant statistical difference in terms of specificity, but the difference in sensitivity and accuracy had statistical significance as the sensitivity and accuracy of the improved group was higher than that of the routine group. Conclusion The multi-directional lawn mower ultrasonic scanning can more easily detect intussusceptions than the conventional scanning method, so that it can reduce missed diagnosis and improve the sensitivity, featuring an important clinical significance, recommended in the clinical diagnosis of infantile acute intussusceptions. |
