Shorter break-in period is a viable option with tighter PD catheter securing during the insertion

Recent single-arm studies reported good catheter outcome despite shorter break-in periods after peritoneal dialysis (PD) catheter insertions. These results were attributed to tight catheter securing during the insertions.


To compare catheter-related outcomes after different break-in periods in the tightly secured PD catheters.

Patients and Methods

The study cohort comprised 48 patients, who underwent catheter insertions with the modified insertion technique. Based on the duration of break-in period, the patients were grouped into a shorter break-in period arm, with break-in period of 7 days or less and a standard break-in period arm, with break-in period of about 2 weeks. Mean patient follow up was 9.68 ± 4.35 months, with a similar follow-up duration between the two break-in period arms (P = 0.94).


In the study cohort, the incidence of pericatheter leaks, pericatheter haemorrhage, catheter malfunction and peritonitis was 2/48 (4%), 1/48 (2%), 1/48 (2%) and 3/48 (6%), respectively. There was no other-site leak, bowel perforation, hernia formation or wound dehiscence. Of these complications, two pericatheter leaks, one catheter malfunction and three peritonitis episodes followed standard break-in periods, whereas, one pericatheter haemorrhage occurred in the shorter break-in period arm.


After a tight catheter securing during the insertions, overall pericatheter leak incidence remained low in the whole study cohort, and it did not worsen despite a shorter break-in period. Future studies with larger patient numbers are needed to validate the role of shorter break-in period in PD practice.
