title: A critical evaluation of laparoscopy in penetrating abdominal trauma.
abstract: One hundred hemodynamically stable patients with penetrating abdominal trauma (65, stab wounds, 35, gunshot wounds) were evaluated with laparoscopy. Sixty percent of the patients had wounds in the thoracoabdominal area or the upper abdominal quadrants and 25% had injuries located in the lower abdomen and flanks. Fifteen percent had epigastric wounds. Twenty-two stabs and 21 gunshots had not penetrated the peritoneum (negative laparoscopic results). Fifty-seven patients had peritoneal penetration and were noted to have hemoperitoneum only (n = 14), hemoperitoneum and solid organ injuries (n = 23), diaphragmatic lacerations (n = 17), and hollow viscus injuries (n = 2) on laparoscopic examination. Three of the 57 patients, one with omental herniation only and two with low grade nonbleeding lacerations of the liver, were managed uneventfully without laparotomy. The remaining 54 patients underwent laparotomy with confirmation of the laparoscopic findings. Seven patients (three with stab wounds and four with gunshots) had additional GI tract injuries seen at laparotomy. The diagnostic accuracy of laparoscopy was excellent for hemoperitoneum, solid organ injuries, diaphragmatic lacerations, and retroperitoneal hematomas. For GI injuries, laparoscopy was found to have a 100% specificity but only a 18% sensitivity. The majority of these discordant findings occurred in epigastric SWs and flank and lower quadrant GSWs, all in patients with undetected hollow viscus injuries. The major role of laparoscopy in penetrating abdominal trauma is in avoiding unnecessary laparotomy in tangential SWs and GSWs. It is excellent for evaluating the diaphragm in thoracoabdominal wounds. Caution is urged in excluding hollow viscus injuries based on laparoscopy.
