Double purse-string craft around the inner cuff: a new technique for an immediate start of CAPD

Abstract

Background: In order to minimize the risk of leakage and displacement, international guidelines recommend that catheter insertion should be performed at least 2 weeks before beginning CAPD. However, the optimal duration of the break-in period is not defined yet. 

Methods: From January 2011 to December 2018, 135 PD catheter insertions in 125 patients (90 men and 35 women, mean age 62,02 ± 16,7) were performed in our centre with the double purse-string technique. Seventy-seven straight double-cuffed Tenckhoff catheter were implanted semi-surgically on midline under umbilicus by a trocar and 58 were surgically implanted through rectus muscle. In all patients CAPD was started within 24 hours from catheter placement, without a break-in procedure. We recorded all mechanical and infective catheter-related complications during the 3 first months after initiation of CAPD and the catheter survival rates.

Results: During the first 3 months the overall incidence of peri-catheter leakages, catheter dislocations, peritonitis and exit-site infections was 2,96% (4/135), 1,48% (2/135), 10.3% (14/135) and 2.96% (4/135), respectively. No bleeding events, bowel perforations or hernia formations were reported. The catheter survival censored for deaths, kidney transplant, loss of ultrafiltration and inability was 74,7% at 48 months. There was no difference in the incidence of any mechanical or infectious complications and catheter survival between the semi-surgical and the surgical groups. 

Conclusions: Double purse-string technique allows an immediate start of CAPD both with semi-surgical and surgical catheter implantation. This technique is a safe and feasible approach in all patients who refer to peritoneal dialysis.

Introduzione

Sebbene la dialisi peritoneale ambulatoriale continua (CAPD) possieda diversi benefici rispetto all’emodialisi (HD), quali una maggiore adattabilità agli stili di vita individuali, una più lunga conservazione della diuresi residua [1,2], una maggiore sopravvivenza nei primi anni di terapia [3,4] e un minore costo economico [5,6], in Italia solo il 13% circa dei pazienti incidenti sono trattati mediante dialisi peritoneale (PD), mentre la prevalenza si attesta intorno al 9.5% [7]. I più recenti dati USA riportano un’incidenza e una prevalenza perfino minori, 9.7% e 7%, rispettivamente [8]. Le ragioni di questo sottoutilizzo sono molteplici: la poca dimestichezza ed esperienza con la metodica da parte dei professionisti, l’errata credenza di inferiorità della CAPD in termini di morbilità e mortalità (elevato timore delle complicanze infettive e convinzione della ridotta sopravvivenza del paziente), la percezione dell’inadeguatezza depurativa delle piccole molecole e infine, in termini economici, un minor rimborso per le strutture sanitarie se confrontato con l’emodialisi.
