Abstract

Background: Exit-site infection (ESI) and tunnel infection (TI) of the peritoneal dialysis (PD) catheter are significant causes of catheter or even method loss as well as patient morbidity. Among the methods that have been in use thus far, the removal and replacement of the catheter often needs to be followed by switching temporarily to hemodialysis, whereas catheter splicing or unroofing of the tunnel tract and shaving/removal of the superficial catheter cuff have not gained universal acceptance thus far. Methods: We treat chronic ESI with exit-site relocation under local anesthetic with removal of the external cuff. For the purposes of this study, we conducted a retrospective cohort analysis of all exit-site relocations performed using that technique over a 5-year period. Results: Twenty-seven patients (16 male, mean age 58 years, range 23 – 81 years) with chronic ESI underwent exit-site relocation under local anesthetic as a day-case procedure. Follow-up was 47.5 ± 22.4 months (range 10.8 – 79.4 months). No dialysate leaks occurred following the procedure. Peritoneal dialysis was resumed immediately. The procedure resulted in long-term resolution of the infection in 20 of the 27 patients (74%). In 7 patients (26%), the catheter had to be removed eventually, either because of ESI recurrence (5 patients) or TI (2 patients), which in 2 cases was subsequently complicated by PD peritonitis, and the patients were switched to hemodialysis. Conclusion: The technique described herein is a safe, straightforward, and effective method for the treatment of chronic ESI while the patient remains on PD and avoids switching to hemodialysis.
