Laparoscopic placement of "self-locating catheter": Our experience and a review of literature

Among the available devices for peritoneal dialysis, the Di Paolo self-locating catheter (SLC) represents a milestone using to its ability to ensure a permanent reliable means of access to the peritoneum. Our experience included 20 laparoscopic peritoneal catheter placements from 2008 to 2011. We performed the laparoscopic surgical technique using 3 trocars: 2 10 mm and 1 5 mm. The technique allows catheter introduction into the pouch of Douglas under direct vision. Among 20 treated patients, 1 died due to causes unrelated to peritoneal dialysis; 1 underwent transplantation, and 1 was switched to hemodialysis because of ultrafiltration failure. The complications included 2 catheter displacements, only 1 of them needing repositioning by open laparotomy, and 1 case of peritonitis. No infection in the subcutaneous tunnel or obstruction and malfunction occurred among our patients. The Di Paolo SLC is similar to Tenckhoff catheter but includes a small tungsten cylinder at the tip that engenders continuous gravity in the peritoneal cavity, producing a reduced risk of dislocation. In a large series of cases, Di Paolo et al. reported a 0.8% dislocation rate after SLC placement compared with 12% using Tenckhoff catheters. They also demonstrated a reduced risk of other complications, such as peritonitis, infection, obstruction, and failure. These data have been confirmed by other authors with smaller case series. Thus, introduction of the SLC and improved surgical techniques result in better efficiency of peritoneal dialysis. © 2012 Elsevier Inc. All rights reserved.
