Urgent-start peritoneal dialysis after laparoscopic dialysis catheter implantation: a single-center experience

Background Appropriate timing of peritoneal dialysis (PD) catheter implantation and PD initiation is important. Several guidelines suggest starting PD at least 2 weeks after PD catheter implantation. Recently, urgent-start PD is widespread throughout the world. However, the ideal time to start PD after laparoscopic catheter implantation is not known. We investigated the safety and feasibility of early initiation (within 7 days) PD following laparoscopic peritoneal catheter implantation. Methods We retrospectively analyzed patients who underwent laparoscopic PD catheter implantation at the Kyoto University Hospital from January 1, 2006, to December 31, 2016. Based on when PD was initiated, the patients were divided into two groups, namely, early group, ≤ 7 days and late group, > 7 days after catheter implantation. Catheter-related complications and catheter survival were analyzed. Results We analyzed 29 and 26 patients in early and late groups, respectively. The age, sex, the incidence of diabetes and APD, and the follow-up period were not significantly different between the two groups. The interval from catheter implantation to the start of PD was 4.28 ± 1.83 and 162 ± 157.8 days in the early and late groups, respectively ( P < 0.01). In a late group, 17 patients (65.4%) underwent catheter implantation using the Moncrief–Popovich technique. The use of bridge hemodialysis was higher in the early group ( P < 0.01). No patients developed dialysate leakage in both groups, and no significant differences were observed for catheter malfunction (24.1% vs. 19.2%, P = 0.66), exit-site infection (ESI, 24.1% vs. 28%, P = 0.87), and peritonitis (7.14% vs. 8.0%, P = 0.91) within 6 months. Furthermore, early initiation of PD did not increase the risk of ESI, peritonitis, and PD withdrawal at 1, 2, and 5 years compared to that in the late group. Conclusions Urgent-start of PD with laparoscopic catheter implantation did not increase infection-related complications and PD withdrawal. Laparoscopic PD catheter implantation may allow the initiation of PD earlier than 7 days after implantation.
