    Abstract:
    STUDY OBJECTIVE: To study exit-site/tunnel infections and catheter outcomes in peritoneal dialysis patients. DESIGN: The study was designed to investigate exit-site (ESI)/tunnel infections (TI) and catheter losses in all chronic PD catheters inserted in ESRD patients from 9/88 to 9/91. SETTING: Tertiary-referral university hospital. PATIENTS AND METHODS: Seventy-three patients (40 males, 33 females) underwent 78 double-cuff coiled swan-neck catheter implantations surgically. The curettage of exit site was performed weekly for tunnel infection refractory to medical management. The subcutaneous cuff was excised in persistent ESI/TI. RESULTS: Fifty-nine episodes of ESI/TI in 34 patients were observed over 946 patient-months. Thirty-nine patients experienced no ESI/TI, 27 patients had one and seven had two or more episodes of ESI/TI. Four patients had five episodes of peritonitis associated with ESI/TI. Eight recurrent episodes of ESI/TI with S. aureus in 8 patients were treated successfully with Rifampin. Seven subcutaneous cuffs were excised successfully in 7 patients with tunnel infection, five with S. aureus and two with Pseudomonas aeruginosa. No catheter was removed due to ESI/TI or ESI/TI associated peritonitis. CONCLUSIONS: Aggressive exit site care including repeated curettage, excision of the subcutaneous cuff and appropriate antibiotics reduced significantly catheter losses related to ESI/TI.
