Abstract titles should be brief and reflect the content of the abstract.
The Stepwise Moncrief and Popovich technique (SMAP), a method for stepwise initiation of peritoneal dialysis (PD) by embedding PD catheter introduced and popularized by Kubota et al. in 1999, is currently used in approximately 25% of PD cases in Japan. While several studies have suggested that the SMAP method may help reduce complications, including PD-related peritonitis, a definitive conclusion has not yet been reached. Moreover, no studies to date have focused on causative organisms, and differences in microbial etiology depending on the catheter insertion technique remain unclear.
We retrospectively analyzed 72 patients who initiated PD at Juntendo University Nerima Hospital between April 2016 and September 2022. Among them, 19 patients underwent catheter placement using the SMAP method (average embedded period 181 days), while 53 underwent direct catheter introduction using conventional (non-SMAP) methods. We compared the two groups regarding the incidence of peritonitis and exit-site infection, the causative organisms, and catheter-related complications at the time of PD initiation over the observation period.
Peritonitis occurred in 10 patients (52.6%) in the SMAP group and in 21 patients (39.6%) in the non-SMAP group. However, Kaplan–Meier analysis revealed no significant difference in the incidence of peritonitis between these two groups. Within the SMAP group, no significant difference in peritonitis incidence was observed between patients with a catheter embedding period of less than 6 months versus those with 6 months or more. Additionally, no significant differences in the distribution of causative organisms were found between the SMAP and non-SMAP groups.
Exit-site infections occurred in 5 patients (26.3%) in the SMAP group and 25 patients (47.2%) in the non-SMAP group. While the Kaplan–Meier analysis did not demonstrate a statistically significant difference, there was a trend toward lower incidence in the SMAP group (P = 0.08). Similarly, within the SMAP group, the duration of the embedded period was not associated with a significant difference in infection rates. There was also a tendency for a lower proportion of Gram-positive organisms among the causative agents of exit-site infections in the SMAP group.
The potential clinical utility of the SMAP method may be further clarified through investigations focusing on causative organisms, particularly in peritoneal dialysis catheter-related infections.
