Experience with over 2500 diagnostic peritoneal lavages.

Trauma centers rely on diagnostic tools to assess internal injuries quickly. Prior research has shown that imaging and clinical exams have limitations in detecting intra-abdominal bleeding. This gap motivated researchers to evaluate diagnostic peritoneal lavage (DPL) as an alternative. DPL has been used for decades but its current role remains uncertain. No prior work had resolved whether newer imaging methods have made DPL obsolete. The study aimed to clarify DPL's accuracy and safety in modern trauma care. Researchers wanted to determine if DPL is still a reliable diagnostic option. They also sought to compare open and closed DPL techniques. The goal was to provide evidence-based guidance for trauma teams.

The researchers aimed to evaluate the diagnostic accuracy and safety of DPL in trauma patients. They wanted to confirm if DPL remains a useful tool in trauma centers. The study focused on both blunt and penetrating injuries. They examined whether DPL results align with laparotomy findings. The team also compared open and closed DPL methods. They sought to quantify complication rates across techniques. The goal was to determine if DPL is still a valid diagnostic test. The study aimed to inform trauma protocols and surgical decisions.

The team analyzed a prospectively collected database of DPL procedures. They included 2501 cases over 75 months at a level I trauma center. They used red blood cell counts to define positive results. For blunt trauma, they considered 100,000/mm³ as positive. For penetrating trauma, they used 10,000/mm³ as the threshold. They compared DPL results with laparotomy outcomes. They categorized procedures as open or closed techniques. They recorded complication rates for each method. The analysis focused on sensitivity, specificity, and accuracy metrics.

DPL showed 95% sensitivity for blunt trauma and 100% for penetrating injuries. The specificity was 99% across both trauma types. Overall accuracy reached 98% in the study population. Most procedures (2409) used the closed Seldinger technique. Open DPL was used in 92 cases due to anatomical challenges. Open DPL had slightly lower sensitivity for blunt trauma (90 vs 95%). It showed higher sensitivity for penetration detection (100 vs 96%). Complication rates were 0.8% overall, with no difference between techniques.

The authors found DPL to be highly accurate and safe in trauma evaluation. They confirmed its sensitivity and specificity for both trauma types. The low complication rate supports its continued use. Both open and closed techniques showed comparable safety. The results suggest DPL remains a valid diagnostic option. The authors propose its use in trauma centers where appropriate. They emphasize the need for proper technique and interpretation. The findings support maintaining DPL as part of trauma protocols.
