Diaphragmatic Hernia and Eventration Diagnosis and Management

Diagnostic Approach

The World Journal of Emergency Surgery recommends starting with chest X-ray (anteroposterior and lateral views) as the first-line diagnostic study for both diaphragmatic hernia and eventration, as hernias may demonstrate bowel gas patterns, air-fluid levels, or visible bowel loops in the thorax, with sensitivity limited to 2-60% for left-sided and 17-33% for right-sided hernias 1, 2
The World Journal of Emergency Surgery suggests that CT scan with contrast enhancement of chest and abdomen is the gold standard for diagnosing diaphragmatic hernia, with sensitivity of 14-82% and specificity of 87%, and key CT findings include diaphragmatic discontinuity, "collar sign", "dangling diaphragm" sign, and herniated organs abutting chest wall 2, 4

Diaphragmatic hernias carry a higher risk of life-threatening complications, including bowel obstruction, strangulation, volvulus, and visceral ischemia, according to the World Journal of Emergency Surgery 1, 4
The Praxis Medical Insights guideline recommends that all diaphragmatic hernias require surgical repair due to the risk of complications, and for stable patients without peritonitis, a laparoscopic approach is acceptable, while for patients with peritonitis or hemodynamic instability, an open abdominal approach is mandatory 3
