# Comparative outcomes of image-guided percutaneous catheterization versus direct visualization catheterization for peritoneal dialysis: A meta-analysis

## TL;DR

A meta-analysis compares two catheterization methods for peritoneal dialysis, finding that image-guided percutaneous catheterization reduces complications but not catheter survival.

## Contribution

This study provides a comprehensive meta-analysis comparing infection and mechanical outcomes of two PD catheterization techniques.

## Key findings

- Image-guided percutaneous catheterization reduces infection complications compared to direct visualization catheterization.
- IGPC also lowers mechanical complications and catheter removal rates compared to DVC.
- No significant difference in one-year PD catheter survival was observed between the two methods.

## Abstract

Debate persists on the optimal catheterization method for peritoneal dialysis (PD). This meta-analysis aimed to compare the outcomes of image-guided percutaneous catheterization (IGPC) versus direct visualization catheterization (DVC) for peritoneal dialysis.

From the inception of the database until July 16, 2024, four databases (Medline, Embase, Web of Science, and the central database) were searched for literature comparing IGPC versus DVC for peritoneal dialysis. Meta-analyses were conducted on infectious complications, mechanical complications, one-year PD catheter survival, and catheter removal rates.

Totally 11 studies were included in this meta-analysis, comprising a total of 8,981 patients, of which 2,518 patients received IGPC and 6,463 patients received DVC. IGPC exhibited lower rates of infection complications (OR = 0.73, 95% CI: 0.54-0.99, P = 0.04) mechanical complications (OR = 0.64, 95% CI: 0.42-0.99, P = 0.04) and catheter removal compared to DVC (OR = 0.63, 95% CI: 0.50-0.78, P < 0.0001). However, there was no significant difference in one-year PD catheter survival between the two groups (OR = 1.33, 95% CI: 0.78-2.27, P = 0.30).

This meta-analysis concluded that IGPC was a safe and effective catheterization method for PD. The results demonstrated that IGPC significantly reduced the incidence of infection complications, mechanical complications, and catheter removal compared to DVC. No notable disparity in one-year PD survival was detected between the two groups.
