Peritoneal Vicenza “Short” Catheter Outcomes and Comparison with International Society for Peritoneal Dialysis Guidelines

Abstract

Introduction: A well-functioning peritoneal catheter is key to success of peritoneal dialysis (PD). The Vicenza “short” catheter is a modified Tenckhoff catheter with a shorter intraperitoneal segment. The aim of this study was to evaluate the incidence of catheter-related complications and catheter survival rate using the Vicenza “short” catheter, according to the goals suggested by the International Society for Peritoneal Dialysis (ISPD) guidelines. Second, we compared insertion techniques used in our center. Methods: This is a retrospective cohort, single-center study analyzing incident PD patients undergoing Vicenza “short” peritoneal catheter placement between January 1, 2015, and December 31, 2019. As clinical outcomes, we evaluated catheter patency at 12 months, exit-site/tunnel infection and peritonitis within 30 days of catheter insertion, visceral injury, or significant hemorrhage during the procedure, in accordance with ISPD guidelines. Results: The percentage of patency at 12 months for all catheter insertion methods was 88.91%, and the percentage for laparoscopic placement was 93.75%. The exit-site/tunnel infection and peritonitis occurring within 30 days of catheter insertion were, respectively, 0.75% and 2.2%; the visceral injury leading to intervention was 0.75%. We did not have any case of significant hemorrhage. All results were in line with ISPD guidelines. Conclusion: We conclude that the Vicenza “short” catheter is a suitable device for peritoneal access. The implantation procedure is safe and easy to perform, and both nephrologists and surgeons can do it. A confident use and a proper implantation of the Vicenza “short” catheter help achieve the clinical ISPD goals for the PD access procedure in terms of catheter survival and complication rates.
