Surgical aspects of continuous ambulatory peritoneal dialysis in infants, children and adolescents
Insights
Surgical techniques improve pediatric peritoneal dialysis. Specialized catheter placement and peritoneography prevent complications, leading to 101 catheter-months without failure in young patients.
Area of Science:
- Pediatric Nephrology
- Surgical Innovation
- Dialysis Technology
Background:
- Continuous ambulatory peritoneal dialysis (CAPD) is a vital renal replacement therapy for pediatric patients.
- Catheter-related complications can significantly impact the efficacy and longevity of CAPD in children.
- Optimizing surgical techniques for peritoneal catheter placement is crucial for successful long-term outcomes.
Purpose of the Study:
- To review the surgical contributions to successful pediatric CAPD.
- To highlight specific surgical procedures for pediatric peritoneal catheter placement.
- To evaluate the impact of surgical interventions on catheter survival and complication rates.
Main Methods:
- Review of experience with 9 pediatric patients undergoing CAPD.
- Development and application of specific surgical techniques for peritoneal catheter placement.
- Utilizing intraoperative peritoneography for assessing catheter function and predicting hernia development.
- Prophylactic repair of subclinical inguinal and umbilical defects identified by peritoneography.
- Inclusion of partial omentectomy in select cases.
Main Results:
- Developed surgical procedures ensure proper catheter position, a watertight seal, and intraoperative functional demonstration.
- Peritoneography accurately predicted clinical hernia development and allowed for prophylactic repair of subclinical defects.
- Partial omentectomy proved beneficial in certain cases.
- Accumulated 101 patient-months of CAPD across 9 pediatric patients without a single catheter failure post-implementation of described techniques.
Conclusions:
- Surgical expertise is paramount for successful pediatric CAPD.
- Specific surgical techniques and intraoperative peritoneography significantly enhance peritoneal catheter function and longevity.
- The described surgical approach has eliminated catheter failures in this pediatric cohort, extending functional catheter lifespan.
Abstract:
The importance of surgical contributions to successful pediatric continuous ambulatory peritoneal dialysis demonstrated in this review of our experience with 9 pediatric patients maintained on such dialysis for 2 to 21 months (mean 11.3 months). Specific surgical procedures for pediatric peritoneal catheter placement have been developed that ensure proper catheter position, establish a watertight seal at the peritoneum and provide for intraoperative demonstration of good catheter function. Peritoneography at the time of catheter placement had predicted accurately later clinical hernia development and may be used to repair prophylactically subclinical inguinal and umbilical defects that are only demonstrable by intraoperative peritoneography. Partial omentectomy also has been helpful in certain instances. Since institution of the techniques described in this report, our 9 young patients have accumulated 101 patient-months on continuous ambulatory peritoneal dialysis without a single catheter failure. The benefits of this as yet unrestricted extension of peritoneal catheter functional life span may be attributed to the catheter-protective features of the continuous ambulatory peritoneal dialysis method itself and the involvement of interested surgeons as active members of the pediatric continuous ambulatory peritoneal dialysis program.
