Abstract

Introduction: The triglyceride (TG) threshold for diagnosis of chylous ascites in patients with portal hypertension remains uncertain.

Methods: Retrospective analysis of lipoprotein electrophoresis was conducted in 286 consecutive ascites samples.

Results: Ascitic TG ≥ 81 mg/dL is 95.4% sensitive and 94.6% specific for chylous ascites diagnosed by the presence of significant chylomicron population.

Discussion: The cutoff for chylous ascites diagnosis should be TG ≥ 81 mg/dL.
