Simultaneous catheter replacement-removal during infectious complications in peritoneal dialysis

The aim of this study was to verify whether the replacement of the peritoneal catheter in a single operation and during infectious complications of peritoneal dialysis is effective and safe. Sixty-eight infectious complications refractory to appropriate antibiotic therapy were treated by this technique: 26 tunnel infections, 22 peritonitis-complicating tunnel infections, 12 refractory peritonitis, and 8 recurrent peritonitis. Operations were successful in all cases of tunnel infection and recurring peritonitis, and in all cases but one of peritonitis-complicating tunnel infection. Ten failures occurred among the 12 catheters removed for refractory peritonitis. Microorganisms cultured in these 10 failures were: Fungi (3 cases), Mycobacterium (2 cases), Pseudomonas (2 cases), Acinetobacter (1 case), Acinetobacter+Pseudomonas (1 case), and Enterococcus (1 case). Complications were 3 one-way obstructions and 2 external dialysate leaks. This study supports the simultaneous catheter replacement-removal procedure during infectious complications of peritoneal dialysis (PD) with the exception of refractory peritonitis; this technique spares the patient the temporary vascular access, the shift to hemodialysis, and a second operation to insert a new catheter. There are few complications.
