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 (p = 0.307). The incidence of postoperative catheter migration was lower using the modified technique (4.3%) than the conventional technique (18.3%) (p = 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 (p = 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.
