I have read with interest the article by Briceño and coworkers1 published in the May 2010 issue of Archives. It is a well-designed study about the usefulness of a carrier-bound fibrin sealant to treat the raw surface of the liver after resection.
One of the secondary outcome measures was postoperative drainage output volume. In their Figure 1, Briceño et al1 present a flowchart in which it can be seen that 25 patients received a major hepatectomy with application of a carrier-bound collagen sponge on the raw surface of the liver. They also wrote that, in the collagen sponge group, 1 or 2 sponges were applied relative to the cut surface.
