Silent Danger: Uncovering Greater Omental Internal Herniation

Abstract

Background: Internal hernias, though infrequent, are significant causes of intestinal obstruction, contributing to 0.2 to 4% of cases. Greater omental hernias, even rarer at 8%, predominantly affect older individuals, where senile atrophy often leads to omental defects.

Objective: This study aims to highlight the importance of considering internal hernias in the differential diagnosis for intestinal obstruction, particularly in patients without prior abdominal interventions or trauma.

Methods: We review a case of a 75-year-old female presenting with symptoms indicative of internal herniation, including the absence of significant historical abdominal insults. Diagnostic strategies involved physical examinations, imaging via X-ray and CT scans, and eventual surgical intervention.

Results: The patient's initial presentation involved subacute obstruction symptoms, progressing to complete obstruction on the second day of admission. Imaging failed to reveal a definitive transition point, but suggested small bowel obstruction. Surgical findings confirmed an intact herniated bowel loop, successfully treated without complications.

Conclusion: Internal hernias should be suspected in patients with intestinal obstruction symptoms, even in the absence of typical predisposing factors. Prompt recognition and treatment are crucial to prevent severe outcomes such as strangulation and necrosis.
