CTICasesDiaphragmatic Herniation and Bowel Obstruction post Liver Resection
Imaging findings
Chest and abdominal radiographs show dilated loops of bowel consistent with obstruction. CT chest and abdomen demonstrate herniation of small bowel loops through a diaphragmatic defect resulting from a previous liver resection, causing mechanical obstruction.
Key takeaways
Iatrogenic diaphragmatic injuries (such as during liver resection or C-section) can lead to delayed diaphragmatic hernia. Because of the pressure gradient between the abdomen and thorax, abdominal contents (typically bowel or omentum) can herniate, potentially causing incarceration, strangulation, or bowel obstruction.
