Paramedian Versus Midline Incision for the Insertion of Permanent Peritoneal Dialysis Catheters

Abstract

A randomized trial was conducted to examine the influence of the site of catheter insertion on the mechanical complications associated with the use of peritoneal dialysis catheters (pericatheter leakage/herniation and tip migration). 37 patients requiring a dialysis catheter for future CAPD were randomized to insertion by either a midline (prior standard approach) or a lateral incision (new approach). Thirteen catheters (6 midline, 7 lateral) failed for mechanical reasons-mainly irreversible tip migration. The one year estimated catheter survival without mechanical failure was found to be similar in the two groups: midline (59%) and lateral (51 %), (0.4<p<0.5).
