Surgical management of refractory exit-site/tunnel infection of Tenckhoff catheter: technical innovations of partial replantation.
OBJECTIVE
Catheter-related infection has been the major cause of catheter removal for peritoneal dialysis (PD) patients. A salvage technique--partial replantation of the infected catheter--was developed in our hospital to rescue catheters with refractory exit-site or tunnel infection.


METHODS
We performed 26 partial replantations of Tenckhoff catheters for 23 patients with refractory exit-site or tunnel infection and 2 patients with near-cuff perforation of the catheter. Their problems were all resolved successfully without interruption of PD.


METHODS
We removed the infected portion of the catheter and preserved the still-functioning internal conduit, connecting it to a divided new catheter. All of the patients resumed PD immediately after the advancement of the new catheter through a new subcutaneous tunnel and exit site on the opposite side.


RESULTS
No technical complications such as disconnection of the catheter or leakage of dialysate were noted. Repeated partial replantation of the catheter was done for 1 patient with a new refractory exit-site infection. Tunnel infection was not an absolute contraindication for this procedure. About one third (34.6%) of our patients had preoperative tunnel infection.


CONCLUSIONS
Partial replantation of a Tenckhoff catheter is a simple and effective procedure for patients with refractory exit-site/tunnel infection and patients with near-cuff perforation of the catheter. Repeated partial replantation is also feasible for repeat exit-site infections.
