LAPAROSCOPY IN TRAUMA

Abstract

Laparoscopy is a nearly century-old technique that has experienced a resurgence of interest from surgeons since the development of technology that has broadened its applications. Although laparoscopy has been used to evaluate patients with possible abdominal trauma, its use for this purpose is limited by the availability of other diagnostic procedures that may be more suitable for particular circumstances and are more accurate for certain injuries. Laparoscopy is contraindicated in patients who are hypovolemic or hemodynamically unstable and should not be performed in patients with clear indications for celiotomy. It may not be appropriate for patients with cardiac dysfunction, nor for those with significant head injuries who are at risk for intracranial hypertension. Its best applications may be in stable patients with stab wounds or those with tangential gunshot wounds of the abdomen. The likelihood of missing hollow visceral injuries depends upon the indications for conversion to celiotomy. If peritoneal violation or the presence of a small amount of blood in the peritoneal cavity is used as an indication for celiotomy, then the missed injury rate will be low but the unnecessary celiotomy rate will be diminished only slightly compared with a policy of mandatory celiotomy. Excessive enthusiasm for laparoscopy in trauma might result in its use when other diagnostic measures or simple observation are more appropriate. The desire to perform a procedure can be compelling, especially in circumstances in which the general surgeon would not operate upon a patient but simply provide postoperative care after other surgeons have operated. The use of laparoscopy for these purposes can only be condemned, as it increases the costs and risks of care without improving the outcome. The role of laparoscopy in trauma is evolving, and further research into its diagnostic role and therapeutic applications is clearly needed.
