Umbilical hernias (UH) have a higher prevalence than previously considered. With the high workload radiologists must endure, UH can be missed when interpreting a computed tomography scan (CT). The clinical implications of its misdiagnosis are yet to be determined. Unreporting could lead to content lesions in surgical approaches and other potential complications. The aim was to determine the prevalence of UH using CT scans, and the incidence of radiological reporting.
A multicenter, cross-sectional study was performed in four tertiary-level hospitals. CT scans were reviewed for abdominal wall defects at the umbilicus, and radiological reports were examined to compare findings. In the case of UH, transversal, anteroposterior, and craniocaudal lengths were obtained.
A total of 1557 CTs were included, from which 971 (62.4%, 95% CI 0.59-0.64) had UH. Out of those, 629 (64.8%, 95% CI 0.61-0.67) of the defects were not included in the radiological report. Smaller UH (x̄: 7.7 × 6.0 mm) were more frequently missed. Of the reported UH, 187 (54.7%) included at least one axis measurement, 289 (84.5%) content description, and 146 (42.7%) whether or not there were complication signs.
There is a high prevalence of UH, and a high incidence of under-reporting. This raises the question of whether this is a population-based finding or the norm worldwide. The reason of under-reporting and the clinical implications of these must be addressed in further studies.
脐疝（UH）的患病率比先前认为的要高。由于放射科医生的工作量很大，在解读计算机断层扫描（CT）时可能会错过 UH。其误诊的临床意义尚待确定。未报告可能导致手术入路中的内容病变和其他潜在并发症。目的是使用 CT 扫描确定 UH 的患病率，并确定放射报告的发生率。
在四家三级医院进行了一项多中心、横断面研究。对脐部腹壁缺损的 CT 扫描进行了回顾，并对放射学报告进行了检查以比较结果。对于 UH，获得了横径、前后径和颅尾径。
共纳入 1557 例 CT 扫描，其中 971 例（62.4%，95%CI0.59-0.64）有 UH。其中，629 例（64.8%，95%CI0.61-0.67）的缺损未包含在放射学报告中。较小的 UH（x̄：7.7×6.0mm）更容易被忽略。在报告的 UH 中，187 例（54.7%）至少包含一个轴测量值，289 例（84.5%）包含内容描述，146 例（42.7%）是否存在并发症迹象。
UH 的患病率很高，而且漏报率也很高。这引发了一个问题，即这是基于人群的发现还是全球范围内的常态。必须在进一步的研究中探讨漏报的原因和这些漏报的临床意义。
