Subcutaneous cuff removal in persistent exit-site/tunnel infections in peritoneal dialysis.
The purpose of this study was to analyze catheter outcome of persistent exit-site/tunnel infections (ESI/TIs) in peritoneal dialysis patients who underwent removal of the subcutaneous cuff due to persistent ESI/TI from January 1989 to June 1994. One hundred and sixty-eight patients (98 male, 70 female) from our tertiary university hospital underwent 177 double-cuff coiled Swan neck catheter implantations surgically. Nineteen patients (11%) had persistent ESI/TIs for more than 6 months. Thirteen persistent ESI/TIs responded to subcutaneous cuff removal. One hundred and fifty-four episodes of ESI/TI in 168 patients were observed over 3189 patient-months (0.58 episodes/patient-year). Nineteen patients (11%) had persistent ESI/TI with Staphylococcus aureus in 12 and Pseudomonas aeurginosa in 7 patients without episode of peritonitis except 2 patients with Staphylococcus aureus. Thirteen persistent ESI/TI resolved after subcutaneous catheter removal without catheter loss, 8 with Staphylococcus aureus and 5 with Pseudomonas. Sixteen catheters were lost due to fungal peritonitis and two secondary to recurrent bacterial peritonitis. None of the catheters were removed as a result of ESI/TI and related peritonitis. Subcutaneous cuff removal in persistent ESI/TI in peritoneal dialysis patients can significantly reduce catheter loss related to ESI/TI.
