目的：分析超声引导下小儿肠套叠水压灌肠复套的危险因素。
方法：回顾性分析50例我院收治的原发性小儿肠套叠患者的临床资料和声像图。分别收集临床资料（性别、年龄、有无呕吐或血便）及超声特征（肠套位置、肠套叠“同心圆”最大径、有无血流信号、有无腹腔积液、有无肿大淋巴结）。通过单因素分析筛选出超声引导下水压灌肠成功后发生复套的危险因素，通过受试者工作特征曲线（ROC）获得肠套叠“同心圆”直径发生复套的截断值。用二分类Logistic回归方程对上述各复套发生的各危险因素进行分析。
结果：性别、年龄、有无呕吐、肠套位置及有无肿大淋巴结对复套的发生无明显影响。而肠套叠“同心圆”最大径超过35mm、出现血便、腹腔积液以及肠套叠套入肠壁无血流信号会使发生复套的机率明显增高（P < 0.05）。二分类Logistic回归分析的优势比（OR）：肠套叠“同心圆”最大径OR：5.886，血便OR：4.207，腹腔积液OR：4.123，肠套叠套入肠壁无血流信号OR：3.556。
结论：肠套叠“同心圆”最大径超过35mm、出现血便、腹腔积液以及套入肠壁无血流信号是超声引导下小儿肠套叠水压灌肠复套发生的重要危险因素。 |

| Abstract: |
| Objective: The purpose of this study was to investigate the risk factors of children re-intussusception of hydrostatic reduction guided by ultrasonography.
Methods: The clinical data and sonograms of 50 cases of primary intussusception in children were retrospectively analyzed. Clinical data (gender, age, presence of vomiting or bloody stool) and ultrasonic characteristics (intussusception location,
diameter of intussusception “concentric circle”, presence of blood flow signal, presence of free peritoneal fluid, presence of enlarged lymph nodes) were analyzed. The risk factors affecting the re-intussusception were screened out by univariate analysis, the cutoff value of the “concentric circle” diameter of intussusception was obtained by the receiver operating characteristic curve (ROC). Binary Logistic regression equation was used to analyze the risk factors for the occurrence of the above mentioned duplicates.
Results: Gender, age, vomiting, intussusception location and enlarged lymph nodes had no significant effect on the occurrence of re-intussusception. However, the diameter of intussusception “concentric circle” is more than 35mm, the occurrence of blood stool, the presence of peritoneal effusion and the no blood flow signal in the concentric wall of intussusception will significantly increase the probability of re-intussusception (P < 0.05). The dominant ratio (OR) of the bivariate Logistic regression analysis was: the diameter of the “concentric circle” of intussusception OR: 5.886, blood stool OR: 4.207, abdominal effusion OR: 4.123, no blood flow signal of the concentric circle of intussusception OR: 3.556.
Conclusion: The diameter of intussusception “concentric circle” is more than 35mm, the occurrence of blood stool, the presence of peritoneal effusion and the no blood flow signal in the concentric wall of intussusception are the important risk factors for children re-intussusception of hydrostatic reduction guided by ultrasonography. |
