Laparoscopy was performed on 33 patients with penetrating abdominal in
juries to identify those with peritoneal penetration. Diagnostic or th
erapeutic manoeuvres were not attempted; evidence of peritoneal penetr
ation mandated exploratory laparotomy. Twenty-two patients had gunshot
wounds and 11 stab wounds. Ten patients had multiple penetrating inju
ries. Intraperitoneal injury was not evident by clinical assessment in
any patient and all were haemodynamically stable. Twenty-three patien
ts underwent negative laparoscopy and no intraperitoneal injury was su
bsequently detected. Laparoscopy demonstrated peritoneal penetration i
n ten patients and subsequent laparotomy detected intraperitoneal inju
ries in nine. No complications of laparoscopy occurred. In stable pati
ents with penetrating trauma and no clinical evidence of intraperitone
al injury, laparoscopy effectively and safely detects those with perit
oneal penetration.
