Controversy about the appropriate evaluation of penetrating abdominal,
flank, and back injuries prompted this retrospective review of 311 patients
at an urban level 1 trauma center over 5 years. Seventy-five (24%) patients
sustained gunshot wounds to the abdomen. All patients with gunshot wounds
underwent exploratory laparotomy; results of 67 laparotomies (89%) were
positive. Of 236 patients sustaining stab wounds (140 abdominal wounds, 51
flank wounds, 26 back wounds, and 19 wounds to multiple sites), 147 were
treated according to a selective protocol, based on results of physical
examination, wound exploration, peritoneal lavage, and ancillary diagnostic
studies. No injuries were found at celiotomy in three (2%) of these 147
patients. One false-negative result of evaluation of a flank wound
occurred. Significant injuries were found in 13 patients (68%) with stab
wounds to multiple sites, 61 patients (44%) with abdominal stab wounds, 15
patients (29%) with flank stab wounds, and four patients (15%) with back
stab wounds. Mandatory exploration of gunshot wounds is justified. Physical
findings of intra-abdominal injury or positive results of peritoneal lavage
identify stab wound victims likely to benefit from surgical exploration. A
policy of mandatory observation or routine celiotomy for treatment of stab
wounds is not justified.
