Overview
Traumatic Abdominal Wall Hernia (TAWH) represents an infrequent form of hernia and constitutes 1% of hernia cases.[1]
Historical Perspective
The first case was reported by Selby in 1906.
Epidemiology and Demographics
There have been 100 cases reported worldwide. The frequency of cases has increased in the last two decades.[2]
Classification
Traumatic abdominal wall hernia is generally classified into three types [3]
- A small abdominal wall defect caused by low-energy trauma with small instruments (e.g. bicycle handlebar)
- A larger abdominal wall defect caused by high-energy transfer such as motor vehicle accident or a fall from a height
- Iintra-abdominal herniation of bowel with deceleration injures (rare)
Pathophysiology
TAWH is defined as herniation of viscera occurring after a force is applied on the abdomen in a patient without preexisting abdominal hernia, resulting in disruption of muscles and fascia while maintaining skin continuity. [4]
Diagnosis
The criteria for diagnosing TAWH were suggested by McWhorten in 1939, and they are:
- Immediate occurrence following blunt trauma
- Severe pain at the site of the injury
- Patient presents within the first 24 hours
- No previous hernia.
Later, these criteria have been modified to include: Intact Skin over the hernia and no evidence of hernial sac during surgery.[5]
