Circulating Cell-free DNA in Patients With Acute Biliary Pancreatitis: Association With Disease Markers and Prolonged Hospitalization Time-A Prospective Cohort Study.

cfDNA, measured by a rapid simple assay, proved a valuable early marker of severity in ABP with clear advantages for prediction of LOS over Ranson and APACHE II. Measurement of cfDNA has the potential to be an effective practical approach to predict the course of ABP and should be further evaluated in larger trials.
