Emergency laparoscopy for abdominal stab wounds.
BACKGROUND
Management strategies for abdominal stab wounds (ASW) in initially asymptomatic patients range from mandatory explorative laparotomy (EL) to conservative approaches with observation alone. Emergency diagnostic laparoscopy (DL) may play a potential role between these two extremes-hence lowering the rate of unnecessary laparotomies and keeping the rate of missed injuries to a minimum.


METHODS
At our institution mandatory EL was carried out in every patient with ASW until 1992. In a retrospective study the charts of 43 patients with ASW were reviewed in terms of initial diagnostic procedures, intraabdominal injuries, and course and length of hospital stay. Between 5/1993 and 4/1995 DL was performed in a prospective study in 15 patients with suspected peritoneal penetration (PP) after ASW according to a standardized diagnostic and therapeutic algorithm.


RESULTS
In 17 patients (40%) EL showed no PP; 15 (35%) had significant intraabdominal injuries, while 11 patients with PP didn't have lacerations of intraabdominal organs, resulting in an overall rate of nontherapeutic laparotomy of 65%. Mortality was 6% (n = 3), average hospital stay 8 days. Primary DL could exclude PP in 10 out of 15 patients (66%). The remaining five patients (33%) showed PP: In two patients with ASW to the right upper quadrant, intraabdominal injuries could be excluded by DL, and in one patient a low-grade liver injury was treated laparoscopically, thus avoiding laparotomy in a total of 87% (n = 13). In two patients with PP laparoscopy was converted to laparotomy: no pathological finding in one case, splenectomy for spleen laceration in the second patient, resulting in a rate of nontherapeutic laparotomies of 7%. All patients in this series had an uneventful course; average hospital stay was 2.4 days.


CONCLUSIONS
DL offers an important diagnostic tool in excluding peritoneal penetration in ASW, hence lowering the rate of unnecessary laparotomies. Given experience and skills, laparoscopy may be used therapeutically in selected cases of ASW.
