Abstract

Background. Malposition of the tip of a continuous ambulatory peritoneal dialysis (CAPD) catheter may impede a dialysis, and an invasive method, such as open or laparoscopic surgery, is necessary to correct its position. The alpha-replacement method is a nonsurgical procedure; however, the reported clinical experience has been limited. We thus reviewed our 19 cases to clarify the efficacy of this method. Method. The alpha-replacement method was used in 19 patients [mean age, 50 ± 14 years old; male/female ratio, 13/ 6; duration of catheter insertion, 23.7 ± 23.9 months; total, 29 times in 19 patients (once in 13 patients, twice in 3, three times in 2, four times in 1 patient)]. All patients received a swan-neck J-type catheter. The procedure was carried out by using a special guidewire within 1-2 weeks after dislocation of the tips. Results. The procedure was successfully performed 22 times in 14 patients (success rate, 78% in each performance). Required time was only 5-10 min in most successful cases. No evident complications were encountered in any case. Conclusions. The alpha-replacement method for a displaced CAPD catheter proved to be effective and safe.
