Abstract
INTRODUCTION: Internal intestinal hernia has been defined as a bulging of the intestines through a normal or an abnormal peritoneal or mesenteric opening. 1 Internal hernias are a rare cause of small-bowel obstruction, with a reported incidence of 0.2-0.9%. 2
PRESENTATION OF CASE: In this report, the patient presented with multiple episodes of intestinal obstruction. High index of suspicion aided the appropriate management of this case. An abdominal CT revealed signs of small bowel obstruction. With negative signs and symptoms indicating adhesions, malignancy or inflammatory causes, mesenteric defect was suspected. When the patient underwent laparotomy, multiple mesenteric defects were found.
DISCUSSION: In the adult population, acquired mesenteric defects are more common than congenital defects. They can be caused by bowel surgery or abdominal trauma. 11 Patients with a history of blunt abdominal trauma may present with late complication caused by a missed diagnosis of an associated injury, such as bowel mesenteric injuries. In this case, the author describes a patient who developed multiple attacks of small bowel obstruction. He had no previous history of similar symptoms but did give a history of recent abdominal trauma managed conservatively. An abdominal CT was performed, and it showed signs of a mesenteric defect. In such a case, early operative intervention is essential to decrease morbidity and increase survival. 16
CONCLUSION: The diagnosis of post traumatic mesenteric injuries can be missed in conservatively managed trauma cases. For this reason, the decision of non-operative approach should be made following the exclusion of associated injuries. (C) 2013 Surgical Associates Ltd. Published by Elsevier Ltd.
