A hernia after open abdomen or trauma refers to a type of abdominal wall hernia that develops when the abdominal wall has been intentionally or unintentionally left open, weakened, or disrupted due to severe injury or emergency surgery.
What it means
In normal anatomy, the abdominal wall (muscles and fascia) holds the internal organs in place. After a major event like:
- Severe trauma (e.g., gunshot, stabbing, motor vehicle accident)
- Damage control surgery (where surgeons intentionally leave the abdomen open due to swelling, infection, or bleeding)
- Multiple emergency abdominal operations
…the abdominal wall may not fully close or heal with normal strength. Over time, a defect forms, and abdominal contents (fat, intestine, or other organs) can bulge through this weak area. That bulge is the hernia.
Why it happens after “open abdomen”
In an “open abdomen” situation, surgeons may temporarily leave the abdominal cavity open or covered with a temporary dressing. Even when it is later closed, the tissues often:
- lose structural integrity
- scar unevenly
- remain under tension or infection risk
- fail to fully re-establish strong fascial closure
This can lead to what’s called a ventral hernia or post-traumatic/incisional hernia.
Key features
- Visible or palpable bulge in the abdominal wall
- Often enlarges with coughing, standing, or straining
- May cause discomfort, pressure, or pain
- In severe cases, risk of bowel obstruction or strangulation
Why it matters
These hernias can be complex because:
- The abdominal wall is already scarred or damaged
- There may be loss of domain (organs have shifted and the abdominal cavity has “shrunk”)
- Prior infection or multiple surgeries make repair more difficult
Treatment
Management is usually surgical and may include:
- Delayed abdominal wall reconstruction
- Mesh repair (synthetic or biologic)
- Component separation techniques
- Sometimes staged reconstruction if the defect is large or complicated
These cases are typically managed by general surgeons with advanced abdominal wall reconstruction experience, sometimes in trauma or hernia specialty programs.
