Simultaneous removal and reinsertion of Tenckhoff catheters for the treatment of refractory exit-site infection.
Exit-site infection (ESI) refractory to medical therapy is an important complication of continuous ambulatory peritoneal dialysis (CAPD). Between July 1994 and June 1998, 28 patients in our hospital underwent simultaneous removal and reinsertion of Tenckhoff catheters for the treatment of refractory ESI. The ESI was caused by Pseudomonas aeruginosa in 22 patients (78%), methicillin-resistant Staphylococcus aureus in 5 patients (18%), and diphtheroid bacilli in 1 patient (4%). The patients had received antibiotic treatment for a mean duration of 11.6 +/- 5.8 weeks (range: 3-28 weeks) before their operations. During each operation, the old Tenckhoff catheter was removed and a new catheter was inserted in the opposite side of the abdomen. CAPD was resumed after two weeks of intermittent peritoneal dialysis. All patients received intravenous antibiotic cover for seven days after the operation. Early post-operative complications were uncommon. At one year after the operation, 22 patients (78%) were free of ESI. Six patients (22%) had a recurrence of ESI 21.3 +/- 6 weeks (range: 16-32 weeks) after their operation. All new infections were treated successfully with antibiotics. Seven patients (25%) had one episode of peritonitis each, all of which resolved with intraperitoneal antibiotic treatment. We conclude that simultaneous removal and reinsertion of Tenckhoff catheters is a safe and effective method for the treatment of refractory ESI. The procedure alleviates the need for temporary hemodialysis and allows an early return to CAPD.
