Objective The aims were to describe the management of umbilical hernias, to define postoperative complications, and to identify the characteristics of patients that were more likely to have spontaneous resolution of their hernia. Methods All patients referred for umbilical hernia at the Children’s Hospital of Eastern Ontario from January 1990 to April 2017 were examined via retrospective chart review. Spontaneous resolution of umbilical hernia was examined using binary logistic regression. Results We included 2621 patients presenting with an umbilical hernia. A total of 1587 (60.5%) patients underwent surgical repair at a median age of 3.6 years (IQR 2.3–5.4). Surgical complications consisted of infection (n=3), bleeding (n=3), hematoma (n=3), and anesthesia-related complications (n=3). For every one-unit increase in defect size, the odds of a spontaneous resolution of the hernia were 5% lower while controlling for prematurity and the presence of comorbidities [adjusted odds ratio (aOR)=0.95; 95% confidence intervel (CI) 0.93 to 0.97]. Premature babies were 80% less likely to experience hernia resolution compared with non-premature babies (aOR=0.20; 95% CI 0.03 to 0.74). Conclusion The odds of spontaneous resolution were lower for premature babies and were negatively correlated with defect size. Data are available on reasonable request.

儿童脐疝自发消退的预测因素

目的 目的是描述脐疝的处理，定义术后并发症，并确定更可能自行解决疝气的患者的特征。方法 对 1990 年 1 月至 2017 年 4 月期间在安大略省东部儿童医院转诊的所有脐疝患者进行回顾性检查。使用二元逻辑回归检查脐疝的自发消退。结果 我们纳入了 2621 名出现脐疝的患者。共有 1587 名 (60.5%) 患者接受了手术修复，中位年龄为 3.6 岁 (IQR 2.3–5.4)。手术并发症包括感染（n=3）、出血（n=3）、血肿（n=3）和麻醉相关并发症（n=3）。缺陷尺寸每增加一个单位，在控制早产和合并症的情况下，疝气自发消退的几率降低 5% [调整后的几率比 (aOR)=0.95；95% 置信区间 (CI) 0.93 至 0.97]。与非早产儿相比，早产儿疝气消退的可能性低 80%（aOR=0.20；95% CI 0.03 至 0.74）。结论 早产儿自行消退的几率较低，并且与缺损大小呈负相关。可应合理要求提供数据。结论 早产儿自行消退的几率较低，并且与缺损大小呈负相关。可应合理要求提供数据。结论 早产儿自行消退的几率较低，并且与缺损大小呈负相关。可应合理要求提供数据。
