Comparative Study of Suture Catheter Insertion Techniques in Dialysis

A recent study has examined the effectiveness of single- and double-purse-string suture catheter insertion methods used in peritoneal dialysis, revealing no significant differences in complication rates or technical survival between the two approaches. This research, published in the journal Renal Failure, provides important insights into catheterization techniques that could influence clinical practices.

The study involved a retrospective analysis of 142 patients who underwent catheterization for peritoneal dialysis using either the single-purse-string method or the double-purse-string technique. The results indicated that complications related to infections and other non-infectious issues were similarly low across both groups in the month following catheter insertion.

Technical survival rates, which measure the longevity of the catheter without requiring replacement, were also comparable. For the single-purse-string group, the survival rates at one, two, and three years were reported as 96.3%, 90.4%, and 85.9%, respectively. In contrast, the double-purse-string group showed survival rates of 89.9%, 86.7%, and 84.8% over the same periods. Notably, patient survival rates remained consistent between both methods throughout the three-year follow-up.

The study concluded that both catheter insertion methods yield similar outcomes in terms of post-insertion complications and technical longevity. The findings suggest that the single-purse-string suture method, which simplifies the surgical process, may be a favorable option for widespread clinical application. This could potentially lead to improved efficiencies in surgical procedures without compromising patient safety or outcomes.

Overall, this research adds to the body of knowledge regarding peritoneal dialysis practices and supports the continued exploration of techniques that enhance patient care while minimizing procedural complexity.
