Single- and double-purse-string suture catheter insertion methods for dialysis have similar complication and survival rates: Study
Outcomes with the single-purse-string technique for peritoneal dialysis catheter placement have been proven to be similar to the double-purse-string method. A recent study was conducted by Xiaoling and colleagues which was published in the journal Renal Failure.
Peritoneal dialysis depends on safe and efficient catheter placement, and reducing complications is important for the outcome of a patient. Although there has been variability in surgical technique, the evidence to clearly support an advantage of one technique over another has been sparse. This study closes that gap by providing strong comparative data at three years' follow-up.
This retrospective study analyzed data on 142 patients who were catheterized for peritoneal dialysis using the single-purse-string suture technique (Group S) or the double-purse-string suture technique (Group D). Patients in both groups were matched for their baseline clinical characteristics to allow for comparison. Both infection-related and non-infection-related complications following insertion of the catheter were assessed, along with technical and patient survival at three years. Kaplan–Meier survival analysis was used to estimate technical and patient survival, and the log-rank test was used to compare outcomes between the two groups.
