Prevalence of Umbilical Hernias by Computed Tomography

Area of Science:

• Radiology
• Medical Imaging
• Abdominal Surgery

Background:

• Umbilical hernias (UHs) are frequently underdiagnosed due to asymptomatic presentation.
• Accurate diagnosis is crucial for appropriate management and patient outcomes.

Purpose of the Study:

• To determine the prevalence of umbilical hernias (UHs) using computed tomography (CT) in a trauma center.
• To assess the extent of underdiagnosis of UHs in radiologic reports.

Main Methods:

• A cross-sectional study analyzed CT scans of adult patients (≥18 years) over a 4-month period.
• Abdominal wall integrity was evaluated, comparing CT findings with radiology reports.
• Registered data included UH dimensions and content, sociodemographic features, and CT scan type.

Main Results:

• A high prevalence of UH was found in 67.6% of 472 CT scans.
• Over 63% of identified UHs were not reported by radiologists.
• UH dimensions varied, with peritoneal fat being the most common content.

Conclusions:

• Computed tomography (CT) is an effective tool for diagnosing umbilical hernias (UHs).
• There is a significant prevalence of UHs in the adult population.
• Radiologic underreporting of UHs is a substantial issue.
