A 56-year-old male presented to the emergency room 4h after a motor car accident during which his right lower quadrant sustained a direct hit by the gear-poke of a car. There was no history of previous abdominal wall hernias. The vital signs were stable. Abdominal examination revealed tender irreducible soft tissue swelling in the right iliac fossa with superficial ecchymosis and positive cough impulse. Muscular guarding, tenderness and rebound tenderness was observed all over the abdomen. Bowel sounds were absent. There were no associated injuries and the rest of the physical examination did not reveal any abnormality. The laboratory investigations were within the normal limits. The radiological examination of the cervical spine, chest and abdomen were normal. Computed tomography (CT) of the abdomen showed a defect in the anterior abdominal wall muscles in the right iliac fossa with bowel loops herniating through the defect [].\nExploratory laparotomy was performed. There was about 200 ml of free blood in the peritoneal cavity and transverse tear of the mid-ileal mesentery causing a gangrene of approximately 20 cm of the bowel. There was also a defect of approximately 8 × 5 cm involving all the layers of the anterior abdominal wall muscles in the right iliac fossa with intact skin. Lacerated muscles were present at the edges of the defect. Active mesenteric bleeding vessels were ligated. The devascularized segment of ileum was resected and end-to-end anastomosis was performed. The mesenteric defect was closed. No other intraabdominal injuries were found. The abdominal wall defect was repaired in layers. The muscular and fascial defects were closed in the anatomic layers. The abdominal incision was closed in a standard manner. Postoperative course was uneventful. Follow up after 2 years showed no evidence of recurrence.
A nearly 7-year-old boy, with no relevant past history, visited our emergency department with abdominal pain and swelling after a fall from his bike. Whilst riding his bike, he had fallen and his abdomen had landed on the handlebar. Immediately after the accident, his mother noticed a swelling where the handlebar had hit his abdomen. They visited the general practitioner on call who subsequently sent him to our emergency department. Apart from pain, he had no other complaints. On physical examination, he seemed to be not ill and he was haemodynamically stable. Examination of the abdomen showed a circular contusion of the skin several centimetres below the umbilicus just on the right of the midline (Fig. ). On palpation, a clear defect of the rectus fascia could be felt. There were no signs of peritonitis suggesting an enteral lesion. He was admitted for observation and discharged the following morning. He was scheduled for surgery 1 week later. During the operation, a skin-line incision was performed over the fascia defect, revealing a rupture of the musculus rectus abdominis, as well as a total rupture of the right rectus fascia (Fig. ). The rectus sheath was closed with a continuous Vicryl suture. The muscle defect was approximated with interrupted Vicryl sutures. The skin was closed intracutaneously. He was discharged the following day and recovered uneventfully.
