#2189 Percutaneous peritoneal dialysis catheter implantation

Abstract

Abstract Background and Aims There are three main techniques to implant a peritoneal dialysis catheter (PDC): percutaneously, laparoscopically or through open surgery; and current guidelines recommend individualising according to previous abdominal surgeries and anaesthetic risk. Recent metanalysis show the percutaneous technique to be safe, non-inferior in catheter survival, and with an equal incidence in mechanic complications (within <3 months after implantation) and infectious complications (within <1 month after implantation) to laparoscopic technique. On the other side, as the percutaneous PDC implantation is a minimal intervention that requires neither surgery room nor over 24h hospitalisation, it allows for a lower waiting time to PDC implantation, a shorter period until usage, and it's economically efficient. Considering these benefits and its non-inferiority described in the literature, our centre started using this technique since 2018. In this study we analyse our results. Method This is an observational retrospective unicentric study, which included the first PDC implantation in adult patients between January 2019 and August 2023, were we analysed the mechanical and infectious complications associated with the implantation technique. All PDC were double-cuff straight Tenckhoff, placed using Seldinger technique with radioscopy. A single dose of prophylactic antibiotic was used. We considered as mechanic complication all those non-infectious incidences that required repositioning or replacement of the PDC within 3 months of implantation (excluding those patients whose catheter was removed because of kidney transplantation, death by other reasons non related to the procedure, or trespass to haemodialysis); and we considered as infectious complications all those peritonitis diagnosed the first month after implantation. Results We analysed a total of 147 patients, 71.4% were male, mean age was 61 years old, and mean kidney function at implantation time was 11.5 ml/min/1.73 m2. We found a total of 8.1% of mechanical complications (33% required repositioning and 66% required replacement) and 5.4% infectious complications. There were no deaths related to percutaneous PDC technique. Conclusion In this study we observe that mechanic or infectious complications associated with percutaneous PDC technique are similar to those published in the literature: ISPD guidelines recommend the incidence of peritonitis associated to catheter implantation to be less than 5%. And though there is no clear percentage of mechanical complications that are considered acceptable or unavoidable, many studies report a survival of 76-86% PDC at 90 days of implantation in percutaneous and laparoscopic procedures, without significant differences between them.
