Abstract
Background:
Catheter implantation techniques for peritoneal dialysis (PD) have advanced significantly in recent years. We aimed to analyze the survival and associated complications of catheters inserted using a new technique that is guided by ultrasound and fluoroscopy and requires minimal tissue dissection. The procedure was performed by nephrologists in the outpatient basis, we compared these results of the minimally invasive insertion with traditional implantation using trocars.
Methods:
A total of 152 PD catheters were placed in 152 patients with stage 5 chronic kidney disease; 62.5% of the patients were men, with a mean age of 56.6 ± 18.5 years. The following two methods were used: minimally invasive insertion (MI group, n = 73) and trocar insertion (T group, n = 79). Patients in both the groups were followed prospectively for 26 months from the date of the first implantation.
Results:
Gender, age, and prevalence of diabetes mellitus were not significantly different between the groups, while the body mass index, presence of obesity, and abdominal scars from previous surgeries were higher in the MI group (p = 0.021). The incidence of catheter dysfunction was lower in the MI group compared to group T (6.8% vs 20.3%; p = 0.019). Exit site infection was also lower with the new technique (4.1% vs. 18.9%; p = 0.005). Further, the cumulative incidence of peritonitis also reduced with MI (p = 0.034). Finally, the overall catheter survival at 1 year was 89%, which has been shown as higher in group MI (95% vs 82% in group T; p = 0.025).
Conclusion:
The MI technique for catheter insertion showed low complication rates and excellent catheter survival as compared to traditional implantation methods; thus, it may be an alternative method for PD catheter placement.
