Mandatory surgical exploration for gunshot wounds to the abdomen has been a surgical dictum for the greater part of this past century. Although nonoperative management of blunt solid organ injuries and low-energy penetrating injuries such as stab wounds is well established, the same is not true for gunshot wounds. The vast majority of patients who sustain a gunshot injury to the abdomen require immediate laparotomy to control bleeding and contain contamination. Nonoperative treatment of patients with a gunshot injury is gaining acceptance in only a highly selected subset of hemodynamically stable adult patients without peritonitis. Although the physical examination remains the cornerstone in the evaluation of patients with gunshot injury, other techniques such as computed tomography, diagnostic peritoneal lavage, and laparoscopy allow accurate determination of intra-abdominal injury. The ability to exclude internal organ injury nonoperatively avoids the potential complications of unnecessary laparotomy. Clinical data to support selective nonoperative management of certain gunshot injuries to the abdomen are accumulating, but the approach has risks and requires careful collaborative management by emergency physicians and surgeons experienced in the care of penetrating injury.
