Chest wall peritoneal dialysis catheter placement in infants with a colostomy.

The presence of a colostomy in infants with end-stage renal disease (ESRD) receiving peritoneal dialysis (PD) is associated with an inherent risk for contamination and the development of a PD catheter-associated infection. A two-piece presternal catheter designed to reduce the incidence of such infections has been used in a small number of children, but the implantation of the catheter is technically difficult, and there is a risk of disconnection of the two parts secondary to rapid patient growth in the first year of life. Alternatively, a conventional Swan neck catheter, larger than typically required, can be placed with its exit site located on the chest wall. Over the past three years, we adopted this novel approach in two patients with ESRD and a colostomy in whom PD catheters were placed at ages 4 days and 12 days, respectively. During a combined follow-up of 50 months, only one episode of peritonitis and no episodes of exit-site or tunnel infection have been observed. This experience supports the use of this unique approach to PD catheter placement in infants with ESRD and a colostomy.
