Peritoneal Dialysis Access: The Surgeon’s Perspective

Abstract

Chronic kidney disease (CKD) is prevalent throughout the world, and peritoneal dialysis (PD) has been a growing mode of renal replacement therapy (RRT) for over four decades. Peritoneal dialysis has several advantages in cost, patient satisfaction, and quality of life, despite accounting for only one in ten patients on dialysis in the United States. In spite of some contraindications and barriers to effective PD, the vast majority of renal failure patients are candidates, especially when in a high-volume program with surgical expertise readily available. Reliable access via an intraabdominal PD catheter is paramount for managing end-stage renal disease patients. Surgical approaches for PD catheter insertion have evolved substantially alongside innovations in catheter design. Recent data suggests that the advanced laparoscopic catheter placement offers the best results and long-term survival. However, image-guided fluoroscopic insertion can be performed without general anesthesia, is highly effective, and is growing in usage. Being able to start PD urgently is vital in avoiding hemodialysis (HD) and its complications, and this is a growing theme worldwide, despite slightly higher morbidity. Infectious and mechanical complications are relatively common and are frustrating to PD patients and the physicians who care for them. Peritonitis and exit site infections require antibiotic coverage and sometimes, surgical intervention. Catheter dysfunction is a frequent mechanical issue requiring a multidisciplinary approach: medical treatment, nurse-administered flushing and clot dissolvers, interventional radiology evaluation and wire manipulation, and surgical laparoscopy for catheter salvage.
