Diagnostic peritoneal lavage
Diagnostic peritoneal lavage (DPL) or diagnostic peritoneal aspiration (DPA) is a surgical diagnostic procedure to determine if there is free floating fluid (most often blood) in the abdominal cavity.〔Rosen 2009, p. 22〕
==Indications==
This procedure is performed when intra-abdominal bleeding (hemoperitoneum), usually secondary to trauma, is suspected.〔Rosen 2009, p. 422-4〕 In a hemodynamically unstable patient with high-risk mechanism of injury, peritoneal lavage is a means of rapidly diagnosing intra-abdominal injury requiring laparotomy, but has largely been replaced in trauma care by the use of a focused assessment with sonography for trauma (FAST scan) due to its repeatability, non-invasiveness and non-interference with subsequent computed tomography (CT scan). Abdominal CT and contrast duodenography may complement lavage in stable patients, but in an unstable or uncooperative persons, these studies are too time-consuming or require ill-advised sedation. Magnetic resonance imaging is extremely accurate for the anatomic definition of structural injury, but logistics limit its practical application in acute abdominal trauma.
The procedure was first described in 1965 by Hauser Root.
