The evolution of abdominal stab wound management

The results of the selective management of 300 abdominal stab wound victims have been reviewed for a 5-year period. Initially the need for laparotomy was evaluated by sinography, later physical examination, and most recently by local wound exploration combined with peritoneal lavage. The use of sinography resulted in an unnecessary laparotomy rate of 38%. Exploration based upon physical findings eventuated in 36% unnecessary laparotomies, of which 79% were negative, 17% morbidity, and no mortality. Local wound exploration followed by peritoneal lavage when peritoneal violation was suspected resulted in 8% unnecessary laparotomies of which half were negative, 9% morbidity, and no mortality. Based on this experience we have adopted the following approach to abdominal stab wounds. Patients with unexplained blood loss or overt signs of visceral injury undergo prompt exploration. In all other cass with intact peritoneum are discharged from the Emergency Department. If peritoneal violation is evident peri toneal lavage is performed. If the lavage is positive laparotomy is undertaken, and if negative the patient is hospitalized for an additional 24 hours of observation.
