In brief
Retrospective analysis of 11 pediatric traumatic abdominal wall hernia cases over 10 years reveals 64% had concurrent intraabdominal injuries requiring operative management, despite CT imaging showing only 20% sensitivity for detecting associated injuries. Authors advocate for early surgical exploration given the high rate of occult intraabdominal injury in this rare but serious consequence of blunt abdominal trauma.

Abstract
Purpose
Traumatic abdominal wall hernia (TAWH) is a rare consequence of blunt abdominal trauma (BAT). We examined a series of patients suffering TAWH to evaluate its frequency, rate of associated concurrent intraabdominal injuries (CAI) and correlation with CT, management and outcomes.
Methods
A Level 1 pediatric trauma center trauma registry was queried for children less than 18 years old suffering TAWH from BAT between 2009 and 2019.
Results
9370 patients were admitted after BAT. TAWH was observed in 11 children, at incidence 0.1%. Eight children (73%) were male, at mean age 10 years, and mean ISS of 16. Six cases (55%) were because of MVC, three (27%) impaled by a handlebar or pole, and two (18%) dragged under large machinery. Seven (64%) had a CAI requiring operative or interventional management. Patients with CAI were similar to those without other injury, with 20% and 50% CT scan sensitivity and specificity for detection of associated injury, respectively. Five patients had immediate hernia repair with laparotomy for repair of intraabdominal injury, three had delayed repair, two have asymptomatic unrepaired TAWH, and one resolved spontaneously.
Conclusions
Children with TAWH have high rates of CAI requiring operative repair. CT scans have low sensitivity and specificity for detecting associated injuries. A high suspicion of injury and low threshold for exploration must be maintained in TAWH cases.
