Laparoscopic management of malfunctioning peritoneal dialysis catheters.

OBJECTIVES

Continuous ambulatory peritoneal dialysis (CAPD) is an established alternative method to hemodialysis for treating end-stage renal disease patients. Malfunction of the peritoneal catheter is a frequent complication in peritoneal dialysis (PD). Laparoscopy is a minimal invasive technique that allows rescue therapy of malfunctioning catheters and consecutive immediate resumption of PD. The purpose of this study is to present our experiences with laparoscopic repair of peritoneal catheter dysfunction

METHODS

Between April 2006 and March 2010, 21 cases of laparoscopic interventions were performed for the salvage of malfunctioning CAPD catheter. Two trocars (5 mm) were used. Recorded data included patient demographics, catheter implantation method, date of malfunction, cause of dysfunction, procedure performed and complications.

RESULTS

The primary etiology of dysfunction was omentum and/or small bowel wrapping with adhesions in fifteen cases, malpositioning in four cases, and tunnel infection in the remaining two cases. Adhesiolysis was performed in cases with adhesions. In the cases with malpositioning but no adhesions, the catheters were repositioned in the pelvic cavity. Two catheters had to be withdrawn and exchanged because of infection. There were no mechanical or infection problems. The overall success rate of catheter function (>30 days after laparoscopy) was 100%, except for two cases in which the catheters had to be removed.

CONCLUSION

Laparoscopy is a safe, highly effective and successful method for the evaluation and management of peritoneal dialysis catheter dysfunction.
