Selective conservatism in abdominal stab wounds: the efficacy of serial physical examination.

An analysis of 186 consecutive patients with anterior abdominal stab wounds in a 2-year period was carried out to assess the efficacy of serial physical examination as the determining factor for the need for laparotomy. Of 106 patients managed by clinical evaluation, the incidence of negative laparotomy was 0.9% and three patients (2.7%) had an "unnecessary" celiotomy. There were no missed injuries or delayed detection of intraperitoneal visceral trauma. The incidence of negative laparotomy among patients subjected to wound exploration +/- peritoneal lavage (n = 41) was 2.4%, and 39 patients had mandatory laparotomy for evisceration, with a negative celiotomy rate of 20.5%. Our experience supports serial physical examination as a highly effective method of "selective conservatism" of anterior abdominal stab wounds. Mandatory laparotomy for evisceration needs further clarification.
