Outcomes of peritoneal dialysis catheter configurations and pelvic fixation

Abstract

Background: Laparoscopic peritoneal dialysis catheter placement has expanded indications, although a relative paucity of data exists about the best configuration for improving outcomes. The purpose of this study is to investigate the role of different catheter configurations and pelvic fixation on catheter and patient outcomes. Methods: Retrospective chart review of patients undergoing peritoneal dialysis catheter implantation between January 1, 2013, and December 31, 2016. All procedures were conducted laparoscopically at a single center. Statistical analyses were conducted using Stata/SE 14.2. Results: Buried catheter configuration was a statistically significant predictor of peritonitis compared to unburied configuration (P = 0.008). Buried catheter was exteriorized at 100 days (SD 107.8). A longer length of time to exteriorization significantly correlated with peritonitis, need for revision, and need for revision pelvic fixation (P < 0.05). Additionally, initial pelvic fixation was a significant predictor of revision (HR 3.94). Conclusions: Peritoneal dialysis catheter placement via a laparoscopic approach can be successfully performed in a diverse patient mix with positive results. However, buried catheter configuration and prophylactic pelvic fixation should be carefully employed in select patients.
