Videolaparoscopy as rescue therapy and placement of peritoneal dialysis catheters: a thirty-two case single centre experience.
BACKGROUND
Malfunction of the peritoneal catheter is a frequent complication in peritoneal dialysis (PD). Videolaparoscopy is a minimal invasive technique that allows rescue therapy of malfunctioning catheters and consecutive immediate resumption of PD. Furthermore, Tenckhoff catheters can be safely positioned in patients with previous abdominal surgery. We analysed the clinical diagnosis, videolaparoscopic treatment and the outcome of PD patients on whom videolaparoscopic interventions had been performed at our centre.


METHODS
Thirty-two cases of videolaparoscopic interventions were performed for salvage of malfunctioning peritoneal catheters, implantation and abdominal surgical interventions in 25 PD patients. The videolaparoscope was inserted through a mini-laparotomy site of 15 mm diameter which was closed with purse-string sutures at the end of the intervention.


RESULTS
Videolaparoscopy was used in 21 cases of catheter malfunction mostly due to omental wrapping (12 cases) and dislocation (five cases). In eight patients with previous surgical abdominal interventions, laparoscopic placement of the PD catheter was performed. In two cases the gall bladder was removed. One case of intestinal occlusion was evaluated laparoscopically in an attempt to minimize invasive surgery. Leakage of the peritoneal fluid presented the only complication caused by insufficient closure of one mini-laparotomy site. Minimal follow-up time of rescued catheters was 5 months. Videolaparoscopy prolonged PD catheter function by a median of 163 days (range 5-1469 days).


CONCLUSIONS
Videolaparoscopy prolongs peritoneal catheter survival by treating directly the causes of malfunction. In patients with preceding abdominal interventions, the PD catheter can be placed safely even in cases necessitating surgical preparation like adhesiolysis.
