ObjectiveTo determine the accuracy and sensitivity of diagnostic peritoneal lavage in the assessment of intra-abdominal injury using the dipstick method.DesignProspective study, involving the performance of diagnostic peritoneal lavage in the out patient department and surgical wards prior to surgical intervention.SettingKenyatta National Hospital-General Surgical and Orthopaedic wards and outpatient department. The study was conducted over a duration of six months, starting from January 1995 to July 1995.ResultsNinety six patients with penetrating (68) and blunt (28) abdominal trauma underwent diagnostic peritoneal lavage as evaluation of the severity of abdominal trauma. Dipstick (combur 9 strips) was used to evaluate lavage effluent for red blood cells, white blood cells, protein and bilirubin. Forty three patients had positive diagnostic peritoneal lavage (DPL) results, of which 40 (93%) had positive findings at laparatomy and three (7%) had negative findings at laparatomy. The remaining 53 patients had negative DPL results and were managed conservatively. One patient with a negative DPL result became symptomatic and had a positive laparatomy. Conservatively managed patients were discharged after 24 hours observations without any complications. DPL had an accuracy and sensitivity of 93% and specificity of 98%.ConclusionDiagnostic peritoneal lavage is a cheap, safe and reliable method for assessment of abdominal trauma. The method is easy to perform by trained junior doctors in the OPD, or as a bedside procedure. Use of this method reduced negative laparotomy rate from 50% to 6.9% and average duration of stay from 6.5 days to 1.9 days. This method is recommended as a basic tool in the assessment of abdominal trauma patients.
