Application for modified partial catheter re-implantation for peritoneal dialysis catheter-related infection

Objective  To observe the effectiveness and safety for modified partial catheter re-implantation for peritoneal dialysis catheter-related infection.

Methods  From January 2010 to April 2020, clinical data were reviewed for 33 surgical patients due to peritoneal dialysis catheter-related infection and a failure of conservative measures. According to surgical approaches, they were assigned into two groups of complete replacement peritoneal dialysis catheter （control, n=15） and peritoneal dialysis partial catheter re-implantation （observation, n=18）. Immediate success rate and surgical-related complications were compared between two groups. The survival of catheters and long-term complications were recorded during a follow-up period of 2 years.

Results  Immediate success rate of operation was 100% in both groups and the incidence of intraoperative complications 0. The survival rate of catheterization was 88.89% and 100% in two groups without statistical difference （P=0.489）. During 2-year observation period, total complication in two groups was 5.56% and 13.33% without statistical difference （P=0.579）.

Conclusions  In patients with peritoneal dialysis catheter-relative infection not responding to conservative measures, modified partial catheter re-implantation is both safe and effective. It is worthy of wider clinical promotions.
