Abstract

◆ Background: Transluminal replacement of a displaced peritoneal catheter (TRC) using a metal guidewire is a noninvasive treatment of catheter displacement with acute malfunction. The "alpha-replacer" is a special guidewire developed specifically for TRC. This wire is usually flexible but becomes harder if coiled in the hand. Application of this unique guidewire might improve the effectiveness of TRC. ◆ Methods: TRC using an alpha-replacer was performed in 10 cases for urgent correction of peritoneal catheter displacement. All patients had received a double cuffed, straight-end swan-neck catheter. ◆ Results: The primary success rate of TRC using the alpha-replacer was 90% (9 of 10 cases). No patients developed complications such as injury of the peritoneum or abdominal organs. Relapse of catheter displacement was observed in 2 cases (20%) within 1 week, requiring surgical intervention to prevent relapse. ◆ Conclusion: TRC using the alpha-replacer as described herein offers effective and safe treatment of peritoneal catheter displacement.
