  • Title: Traumatic abdominal wall herniation.
    Author: Tan EY, Kaushal S, Siow WY, Chia KH.

    Abstract:
    Most reported cases of traumatic abdominal wall herniation result from seatbelt or handlebar injuries. The diagnosis is often made on physical examination or abdominal computed tomography (CT). We report a 59-year-old man with traumatic herniation through the rectus muscle following low-velocity blunt abdominal trauma. This patient was initially thought to have a rectus sheath haematoma and initial CT showed a soft tissue haematoma over the left lower anterior abdominal wall but no herniation. The traumatic herniation was diagnosed four days later, and confirmed on CT. Intraoperatively, a segment of the sigmoid colon was found to have herniated through the rectus defect and was gangrenous with impending perforation. A left hemicolectomy followed by primary repair of the defect was done. This case highlights the need for a high index of suspicion for traumatic herniation in patients who sustain low-velocity blunt abdominal wall trauma even when initial CT scans are negative.
