Abstract

INTRODUCTION:

Long-term use of peritoneal dialysis catheter is associated with complications such as infection and malfunction, necessitating removal of catheter with subsequent reinsertion or permanent transfer to haemodialysis. This study aims to investigate the outcome in patients who underwent reinsertion.

METHODS AND MATERIALS:

A single-centre retrospective study was performed in Singapore General Hospital for all adult incident peritoneal dialysis patients between January 2011 and January 2016. Study data were retrieved from patient electronic medical records up till 1 January 2017.

RESULTS:

A total of 470 patients had peritoneal dialysis catheter insertion with median follow-up period of 29.2 (interquartile range = 16.7-49.7) months. A total of 92 patients required catheter removal. Thirty-six (39%) patients underwent catheter reinsertion. The overall technique survival at 3 and 12 months were 83% and 67%. Median time to technique failure of the second catheter was 6.74 (interquartile range = 0-50.2) months. The mean survival for patients who converted to haemodialysis and re-attempted peritoneal dialysis was comparable (54.9 ± 5.5 vs 57.3 ± 3.6 months; p = 0.75). Twelve (13%) patients had contraindication for peritoneal dialysis and were excluded from analysis. Of 11 patients who required catheter removal due to malfunction, 7 (64%) underwent catheter reinsertion and 6 (86%) patients ultimately converted to haemodialysis during study period. Of the 69 patients who had catheter removal due to infection, 29 (42%) underwent catheter reinsertion and 8 (28%) patients eventually converted to haemodialysis during the study period.

CONCLUSION:

Patient survival was comparable between patients who re-attempted peritoneal dialysis and patients who transferred to haemodialysis. Patients who had previous catheter removal due to infections had favourable technique survival than those due to catheter malfunction.
