Laparoscopy in penetrating abdominal trauma

Abstract

BACKGROUND: Penetrating abdominal trauma (PAT) poses a significant challenge to trauma surgeons. There is no doubt that persistent hemodynamic instability or signs of peritoneal irritation warrant immediate laparotomy. If the patient is hemodynamically stable and has equivocal abdominal examination findings, diagnosis may be obtained by laparoscopy. METHODS: The goal of this article is to evaluate the role of laparoscopy in the management of PAT. RESULTS: Patients with penetrating trauma to the thoracoabdominal and anterior abdominal wall are good candidates for laparoscopic evaluation. The peritoneal cavity and its contents, including the retroperitoneal space, can be thoroughly examined easily and safely. The main benefits of laparoscopy include the reduction of nontherapeutic laparotomies, identification of mostly intra-abdominal injury, and provision of potential therapy for some cases. Diagnostic laparoscopy has a high overall diagnostic accuracy, reduced morbidity, and shortened hospital stay and is also cost-effective. While laparoscopy has some limitations in the diagnosis of hollow viscus injury, it can detect and repair diaphragmatic injuries accurately and exclude the risk of nontherapeutic laparotomy due to a nonbleeding injury of the solid organs. CONCLUSIONS: The use of laparoscopy as a diagnostic or therapeutic method in patients with PAT is reserved only for hemodynamically stable patients and uncertain findings of peritonitis. Laparoscopy is an efficient and effective diagnostic tool when used by a well-trained surgeon. With experience, an increasing number of surgeons are using laparoscopy as an additional diagnostic tool for PAT in stable patients. With more experience and skills, laparoscopy may be used more therapeutically in selected patients. Minimally invasive surgery has already established itself as a useful tool in the management of PAT. The future seems to be promising for this field of surgery by innovative developments in computer technology and robotic systems.
