    Abstract:
    PURPOSE: Peritoneal dialysis (PD) catheter tip migration accounts for the majority of cases of PD catheter malfunction. In this case series, we described our experiences of using a modified PD catheter implantation approach through a site that is lower than the site that is conventionally used, to reduce catheter malfunction. METHODS: We retrospectively identified 76 patients who received PD catheter implantation at the Affiliated Wujin Hospital of Jiangsu University, among whom 39 received the traditional approach of low-site insertion and 37 received a modified approach of very-low-site insertion. All participants were followed up for at least 2 years after PD catheter implantation, and the development of catheter dysfunction or death during this period was monitored. RESULTS: We found that the survival rate of the initially inserted catheter was 75.68% among the very-low-site group. This survival rate was significantly better than that observed among the low-site group (48.72%; p = 0.029). Kaplan-Meier curves of the initial catheter survival also showed that the catheter survival was significantly higher in the patients in the very-low-site group than those in the low-site group (log rank p = 0.012). Complications, such as catheter tip migration, were not observed in the very-low-site group, while tip migration occurred in 15.38% of the patients in the low-site group (very-low-site group vs low-site group: p = 0.039). CONCLUSIONS: A safe and simple PD catheter implantation can be performed either through the low-site approach or the very-low-site approach.
