Peritoneal dialysis (PD) catheter exit-site care is critically important for the prevention of catheter-related infections (CRIs) and subsequent peritonitis. The postoperative management of the site is particularly essential due to its susceptibility to slow healing and infection. Despite the recent use of negative-pressure wound therapy (NPWT) for a wide variety of wounds, few studies have investigated the effectiveness of NPWT for PD catheter exit sites. In this study, 30 patients with

... ge renal disease who underwent simultaneous PD catheter insertion and exit-site formation were randomly assigned to receive NPWT (NPWT group) or conventional dressing (non-NPWT group) for the first seven postoperative days. The exit-site scores on the seventh postoperative day and over 180 days were lower in the NPWT group than in the non-NPWT group (p = 0.0049 and p = 0.007, respectively). There were no statistically significant differences between the time to first CRI and PD-related peritonitis between the two groups. There was one case of CRI with relapsing peritonitis and catheter loss in the non-NPWT group. These findings demonstrate the association between NPWT and low exit-site score. NPWT can be recommended for the management of PD catheter exit sites in the early postoperative period.
