Background
To evaluate the efficacy and safety of ultrasound‐guided percutaneous peritoneal dialysis catheter insertion using multifunctional bladder paracentesis trocar.
Methods
A retrospective review of 103 ESRD patients receiving percutaneous PD catheter insertion using a multifunctional bladder paracentesis trocar under ultrasound guidance at a single center between May 2016 and May 2018. Mechanical complications and catheter survival were evaluated over a 12‐month follow‐up.
Result
Catheterization using this technique required only 10‐30 minutes from the beginning of local anesthesia to the end of skin suture at the puncture site (mean 18 ± 7 minutes) and an incision length of 2‐4 cm. Moreover, only four of 103 cases required catheter removal due to poor drainage within one month after surgery, with a success rate of 96.19%. Among failures, omentum wrapping was cause in two cases, catheter displacement in one case, and protein clot blockage in one case, while there were no instances of organ injury, severe hemorrhage, peritubular leakage, hernia, peritonitis, or exit infection within one month of PD catheter insertion. Catheter survival at 1 year was 92.2%.
Conclusion
Percutaneous PD catheter insertion using a multifunctional bladder paracentesis trocar and ultrasound guidance is a feasible technique for ESRD patients.
Background: We modified the blind Seldinger technique by incorporating ultrasound guidance and the use of a multifunctional bladder paracentesis trocar for PD catheter (PDC) placement, which can be easily performed by a nephrologist and is a feasible technique. To compare success rates and safety of our modified percutaneous PD catheter placement technique to open surgery.Methods: Two hundred and twelve stage-5 chronic kidney disease(CKD) patients receiving PD therapy from June 2016 to June 2019 were included, 105 patients treated by ultrasound-guided percutaneous placement of peritoneal dialysis catheters using a multifunctional bladder paracentesis trocar (Group A) and 107 patients receiving open surgical placement (Group B). Outcomes of patients via either catheter placement technique were retrospectively compared. The clinical success rate as defined by proper catheter drainage within 4 weeks after placement, complication rates (both technical complications and infections), and 1-year catheter survival were compared.Results: There was no significant difference in sex ratio, age, or previous abdominal surgery history between groups (P > .05). Both surgical time and incision length were significantly shorter in Group A than in Group B (P < .05). Clinical success rate was also higher inGroup A (P < .05). Moreover, Group A demonstrated lower overall complication rates (P < .05) and lower incidence rates of early peritonitis, initial drainage disorder, and peritubular leakage (all P < .05). One-year catheter survival was also higher in Group A (P < .05).Conclusion: Percutaneous placement of PD catheters using our modified technique demonstrates superior success rates and safety compared to open surgery. In addition, our modified technique can be a better alternative to traditional Seldinger percutaneous catheterization for its higher success rate and safety, more accurate positioning.Abbreviations: CKD = chronic kidney disease, PD = peritoneal dialysis, PDC = PD catheter, VAS = visual analogue score.
