Abstract: Objective: By improving method in the percutaneous puncture Seldinger technique for peritoneal dialysis catheterization, the success rate of catheterization is improved, and the surgical complications during the puncture process are avoided. Materials and Methods: 24 patients with end-stage renal disease dialysis who underwent Seldinger puncture peritoneal dialysis catheterization were enrolled, 10 patients with conventional puncture group,14 patients with modified percutaneous group. The modified method includes the assistance of preoperative and intraoperative ultrasound techniques, and the interventional vascular sheath puncture set is used instead of the conventionally used puncture needle or Veress needle. The success rate of the conventional group and the modified group is compared. RESULTS: There was no significant difference in age, sex ratio, and primary disease between the modified puncture group and the conventional puncture group (P>0.05). The success rate of routine puncture was 70%, and it was 100% after improvement, which was significantly improved (70% vs. 100%, P<0.05). Catheterization-related complications occurred in 2 patients in the routine group, 1 patient developed catheter dysfunction, and 1 patient in the modified group developed bleeding. There was no difference in catheter-related complications between the two groups (30% vs. 7.1%, P >0.05), there was no major bleeding requiring intervention, leakage of peritoneal fluid, infection, abdominal organ injury. Conclusion: The improved percutaneous peritoneal dialysis catheterization technique and procedure can improve the success rate of puncture and avoid complications such as catheter related bleeding and abdominal organ injury.
