Assessment of complications and short-term outcomes of percutaneous peritoneal dialysis catheter insertion by conventional or modified Seldinger technique.

OBJECTIVE

To explore the efficacy and short-term complications of a modified technique to percutaneously insert a peritoneal dialysis catheter.

METHODS

We reviewed the outcomes of 94 patients who underwent peritoneal dialysis catheterization between October 2017 and April 2020. Of these, 47 cases were placed by a conventional Seldinger technique, whereas 47 cases were placed by a modified technique based on the Seldinger method. The success rates of the catheter insertion and three-month postoperative complications were compared between these two groups.

RESULTS

The catheter insertion success rates were comparable between the two groups: 93.6% in the conventional technique group and 97.9% in the modified technique group ( = 0.307). The incidence of postoperative catheter migration was lower using the modified technique (4.3%) than the conventional technique (18.3%) ( = 0.037). None of the patients in the modified technique group had postoperative dialysate leakage, whereas this occurred in 9.0% of patients in the conventional technique group ( = 0.036). There were no statistically significant differences in the incidence of postoperative bleeding, infection, or visceral damage between the two groups.

CONCLUSIONS

The modified Seldinger technique for percutaneous peritoneal dialysis catheter insertion reduced the short-term postoperative complications of catheter migration and dialysate leakage, with a comparable successful catheter insertion rate compared with the conventional Seldinger technique.
