Objective:
Single- and double-purse-string suture methods are both widely used in open surgical catheterization for peritoneal dialysis. This study aimed to compare the post-insertion complications and technical survival of the two methods.
Methods:
This retrospective study matched 142 patients who underwent peritoneal catheterization using the single- (Group S) or double- (Group D) purse-string suture method. Baseline clinical data and complications were recorded, and technical and patient survival rates were evaluated over 3 years.
Results:
There were no significant intergroup differences in terms of infection complication rates (S, 2.8% vs. D, 5.6%, p = 0.377) or non-infection complication rates (2.1% vs. 2.8%, p = 1.000) within the first month post-insertion. The Kaplan-Meier estimates of technical survival at 1, 2, and 3 years were 96.3%, 90.4%, and 85.9% in group S and 89.9%, 86.7%, and 84.8% in group D, respectively (log-rank test, p = 0.439). Additionally, patient survival rates were comparable between groups over the 3-year follow-up (log-rank test, p = 0.647).
Conclusions:
This study revealed that the single- and double-purse-string suture catheter insertion methods have similar post-insertion complication and technical survival rates. These data suggest that the single-purse-string suture method can be adopted as standard practice for peritoneal dialysis catheter placement.
