Recent advances in peritoneal dialysis catheter placement: the association between method of insertion, operator, and prior abdominal surgery and outcomes.

Purpose of review: Peritoneal dialysis (PD) is associated with comparable outcomes to hemodialysis and is much less expensive to provide in most parts of the world. A well functioning PD catheter is required, but complications are frequent, and while there are guidelines for the placement and care of a PD access, they are based on low-quality evidence.

Recent findings: Data reporting the outcomes of percutaneous, as compared to surgical pathways for placement of catheters and the role of operator type in determining outcomes are examined. The impact of prior abdominal procedures on patient selection and the prognostic importance of the presence of adhesions at the time of catheter insertion are reviewed.

Summary: There are conflicting data about the relative merits of percutaneous as compared to surgical placement of catheters that may relate to differences in patient selection, operator experience, or operator volume. Prior abdominal procedures are not associated with worse PD catheter outcomes and likely should not influence patient selection, except in exceptional circumstances. Finally, the presence of adhesions is associated with a higher risk of complications. However, even in the presence of adhesions, the termination of PD therapy and need for re-intervention occurs in <20% of patients.
