ABSTRACT
BACKGROUND: Traumatic abdominal wall hernia (TAWH) is a rare type of hernia occurring secondary to blunt trauma to the abdomen. Its management remains controversial within the surgical community, mainly due to complexities in diagnosis, appropriate surgical approach and timing of closure. METHOD: Cases were identified retrospectively, via interviews with trauma surgeons at a Tertiary Trauma Centre, the Royal Brisbane & Women's Hospital, in Brisbane, Australia. In addition, data were collected via in-house trauma and operative databases. RESULTS: Five cases of TAWH were identified over a 3-year period. All cases involved injuries sustained from motor vehicle or motor bike accidents. Diagnosis was purely clinical in one case and clinically suspected, then confirmed by computed tomography in the remainder. Herniation was managed by immediate closure in one instance, delayed/staged closure in three cases and conservative management in the remainder. In addition, three of the five patients were obese. At minimal 3-month follow-up, no evidence of recurrence of herniation was present in four of the five cases. One case was lost to follow-up. CONCLUSIONS: TAWH is a complex injury to manage and no one approach is all encompassing. Correct diagnosis is essential as this allows proper planning for the method and timing of repair. This series highlighted that incorrect seatbelt placement, especially in the obese population, may be a risk factor for increased incidence of TAWH.
