P-042 POSTTRAUMATIC HERNIAS: AN UNKNOWN PATHOLOGY

Abstract

Abstract Introduction Posttraumatic hernias are a rare pathology. The mechanism is due to increased abdominal pressure during trauma causing disruption muscle planes. Case description We report three cases of this patology: One of them is a women who suffered a sigmoid perforation due to a traffic accident. After sigmoidectomy and primary abdominal wall closure the patient presented bilateral abdominal. hernias. The second case is about an elderly woman who fell down a subway staircase. The patient presented with a fracture of the left clavicle, fractures of four ribs and left lumbar haematoma. Two months after the trauma she had a left lumbar hernia. The latest case is about a young man who was involved in an accident while riding a motorbike, pinning the handlebars. Physical examination revealed an oedema of the abdominal wall. He had an abdominal hernia with omentum inside. Bilateral hernioplasty was performed on the first one. Biosynthetic mesh on the second one. Laparoscopic correction of the defect with polypropylene mesh fixed with tackers in the third case. Discussion Traumatic abdominal hernias have a estimated incidence of 0.07 to 0.2% of all abdominal trauma. We use two diagnostic criteria: suffering a trauma and the absence of a previous hernia in the same location. In this context, it is important to confirm the presence or absence of a hernia by CT scan. Conclusion The treatment of choice in these cases is the use of mesh because it decreases the rate of recurrence.
