Keywords: NPWTi - Negative pressure wound therapy with instillation, NPWT - negative pressure wound therapy, gentamicin-collagen sponge, Crohn’s colitis


Negative pressure wound therapy (NPWT) is extremely important in the treatment of difficult wounds in patients with proctological diseases, including patients with Crohn's colitis. Despite the many advantages of this therapy, it has some limitations, including the lack of bactericidal activity. Hence, NPWT is combined with antibacterial products. One of them is the gentamicin-collagen sponge, presented in the three cases described below. The combination of the gentamicin-collagen sponge with NPWT may be beneficial in difficult wounds with a high risk of infection, and also in patients with impaired wound healing.

[27] Timmers et al. in 2009 (21) demonstrated the usefulness of NPWTi in patients with
osteomyelitis of the pelvis or lower extremities in a retrospective case–control cohort study.
In addition to systemic antibiotic therapy, patients received either NPWTi using
polyhexanide or were additionally treated with gentamicin-polymethacrylate beads. The
rate of infections was significantly reduced in the NPWTi group compared with the usual
control group [3/30 (10%) versus 55/93 (58·5%), P < 0·0001].
