title: Peritoneal lavage: a useful diagnostic adjunct for peritonitis.
abstract: Diagnostic peritoneal lavage (DPL) was used to aid in the rapid diagnosis of peritonitis in 138 patients for whom standard diagnostic criteria were not applicable because the patients had altered sensorium, were elderly, or had multiple medical problems. There were abnormal results in 77 patients, and all but one patient had peritonitis. Sixty-five patients had lesions that could be cured only by operative means; 54% of this group of extremely ill patients survived. Of 61 patients with negative results of DPL, only one had intraperitoneal inflammation (acute cholecystitis), which occurred 4 days after DPL. We believe DPL is a useful procedure for the detection of peritonitis in a critically ill subset of patients for whom the standard diagnostic criteria were not available.
