Biological Meshes in Infected Fields: a Randomized Controlled Trial

patients will undergo the implantation of a biological mesh (after debridement and treatment of the infection) at the same time as the primary operation, or within one month of randomization.

patients undergo traditional wound care (debridement and treatment of infection), without placement of a biological mesh. For arm B, the common wound care used follows the normal practice of the treating surgeon, except the placement of the biological mesh, which must not be performed within 6 months of randomization In cases of treatment failure at 6 months, patients of arm B are allowed to undergo any treatment which the treating surgeon views suitable, including a surgical procedure with implantation of a biological mesh
