Comparative Study Clinical Trial
Evaluation of diagnostic peritoneal lavage in stable patients with gunshot wounds to the abdomen.
Diagnostic peritoneal lavage (DPL) is used to diagnose intra-abdominal injury in patients with stab wounds and blunt trauma. Because exploratory celiotomy is routinely performed on patients with gunshot wounds to the abdomen, DPL is rarely employed. However, several studies have questioned routine exploration and have drawn attention to the associated morbidity of negative celiotomy. Diagnostic peritoneal lavage is an easily performed and inexpensive test that may be useful in this situation. ⋯ Clinical judgment is highly accurate in separating patients with tangential gunshot wounds to the abdomen from those with intra-abdominal injury but may miss patients with intra-abdominal hemorrhage. Diagnostic peritoneal lavage is highly predictive of the presence of intra-abdominal injury. The return of gross blood on aspiration or a lavage red blood cell count greater than 10 x 10(9)/L should prompt an urgent celiotomy. Missed injuries are rare and most likely to be bowel perforations. Diagnostic peritoneal lavage is an objective test that may augment clinical judgment in selecting hemodynamically stable patients with potential tangential gunshot wounds for observation and is especially useful in identifying intra-abdominal hemorrhage.
