Rodriguez, 2006 / Pancreatic stump leak (PL) related complications / 22 / US $/NR (2004) / - / - / - / - / The average patient with PL-related problem incurred a total cost that was 2.01 times greater than the average patient in the no-PL group. This yielded a cost differential of $14,179 [17,581], which was largely accounted for by hospital-related costs. A decision analytic model developed to evaluate threshold costs showed thata hypothetical intervention designed to reduce the complication rate of distal pancreatectomy by one third would be financially justifiable up to a cost of $1418 [1758] per patient. Alternatively, an intervention that reduced PLs to 0% could cost up to $4254 [5274] and still be economically justified. Many of the PLs were manifesting as both a fistula and a sterile collection, or a fistula and an abscess.
