We reviewed the cases of twenty patients who had a fracture or
disruption of the disc space of a lower thoracic or lumbar vertebra that
was associated with a low-velocity-missile wound to the abdomen. All of the
patients underwent an exploratory laparotomy at the time of admission and
all received broad-spectrum antibiotics for a minimum of two days. None of
the patients had an immediate laminectomy or an immediate debridement of
the paraspinal area. In eight patients the gastrointestinal tract was not
perforated, and none of them had evidence of infection. In four patients
the stomach and small bowel were perforated by the bullet before it struck
the vertebral column, and none of them had meningitis, paraspinal
infection, or osteomyelitis. In contrast, meningitis, paraspinal infection,
or osteomyelitis did develop in seven of eight patients in whom the bullet
perforated the colon before it hit the vertebra. Perforation of the colon
by a low-velocity missile before the missile fractured the thoracic or
lumbar vertebra was associated with a high incidence of infection. The
appropriate management may require early operative intervention. This is in
contrast to the non-operative approach that has been advocated for
low-velocity gunshot wounds to the spine. We agree that a non-operative
approach is indicated for gunshot wounds of the abdomen that do not involve
the colon.
