Depends upon type of injury', 'role': 'user'}, {'content': 'Answer: B \nExplanation: Laparotomy by midline incision is the "gold standard" therapy for intra-abdominal injuries. It is definitive, rarely misses an injury, and allows for complete evaluation of the abdomen and retroperitoneum. All patients with hypotension, abdominal wall disruption, or peritonitis need surgical exploration. In addition, the presence of extraluminal, intra-abdominal, or retroperitoneal air on plain radiograph or CT should prompt surgical exploration. Ref: Scalea T.M., Boswell S.A., Baron B.J., Ma O.J.
